--- 5.0.2 2013/10/16 yaz-ztest returns schema for MARCXML test records. SRU require that recordSchema for records. GFS: make surrogate diagnostic when yaz_record_conv_record fails - instead of non-surrogate diagnostic. This is a per-record failure. GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration may refer to multiple listeners now. Attribute listenref is a comma separated list of listen IDs. GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f option is given for GFS, the dirname of filename (for -f) is used as prefix for options such as cql2rpn, ccl2rpn, etc. Content-Type charset fixes YAZ-701 . Do not inspect charset in Content-Type header for SOAP when decoding SRU. The payload (XML) itself tells what encoding it is. In response, never supply encoding in Content-Type. The response payload (XML) tells what it is (with no encoding in XML it's UTF-8). HTTP decoding: allow blanks in URL paths YAZ-700 --- 5.0.1 2013/10/04 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics and facets. Ensure recordData and recordSchema are always present in record element, because they are required. Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used outside YAZ. Simplify in a lot of places using odr_strdupn. odr_create_Odr_oct: null terminate the buffer. Some applications rely on it. --- 5.0.0 2013/10/01 Increase various buffers in GFS's statserv_options_block Change many 'unsigned char *' to 'char *' for ODR-related utilties. This change makes many type-casts redundant, and, thus simplifies code. Remove last bits of WAIS support. Remove member 'size' from Odr_oct. Slim down the public part of 'struct odr'. Most elements are not part of struct Odr_private. Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier versions of SRU, yaz-client and zoom C are using SRU 1.2 by default. In particular facets are supported in both client - and server side. Facets are also supported for Z39.50 and is carried in additionalSearchInfo of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA "Facet-1" in oid.csv. The info is defined in facet.asn (which covers both request/response). This is what a search handler in the GFS will see (regardless of whether operating in SRU mode or Z39.50). Changes to the srw.h (SRU/Solr) definitions include: - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query (char*), which replace union query and query_type (int). This is because SRU 2.0 supports a queryType parameter. This also means that, to carry PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than x-pquery=PQFstring (extention parameter). The extension parameter is still supported. - New element, packing, that has information about SRU 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping). New element in Z_SRW_searchRetrieveResponse, resultCountPrecision. New element, packing, in Z_SRW_explainRequest. New elements in Z_SRW_scanRequest, queryType and scanClause. These replace query_type and scanClase untion. This is similar to what happend to search. --- 4.2.69 2013/10/01 GFS: log when closing down - at least SIGTERM YAZ-684 Also change formatting WRT PID logging a bit. Improve display of MARC records with multi-byte subfield IDs YAZ-695 In some rare cases subfield identifiers are multi-byte characters. This will try to deterime length of those and split accordingly. This affects display in line mode as MARCXML/MarcXchange. The encoding of ISO2709 is the same. Change inp argument to const for yaz_read_UTF8_char. yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693 Better check of marc leader info YAZ-691 Problem is that some systems generate MARCXML/MarcXchange with funny headers. These will not work if encoded as ISO2709. Some tests produce new output, due to updated warning messages cql2pqf: allow PQF queries from stdin (because CQL is also allowed) yaz-client: display MAB records YAZ-689. Thanks for Heiko Jansen for this patch. New utility z_get_HTTP_Response_server which allows both HTTP server name and HTTP server URL to be given in response. Debian: do not depend on obs tcl8.3. Debian: do not depend on obs libicu36-dev. --- 4.2.68 2013/09/23 GFS: pass additionalSearchInfo to search memeber search_input if given. Otherwise pass otherInfo. Request for facets and other search related things will be passed there in future versions of YAZ. New ZOOM setting, authenticationMode, which allows authentication paramters to be encoded in the URL rather than via HTTP Basic auth. YAZ-686 rpn2solr: fix nested AND/OR handling. YAZ-685 Add comparison routines for some Z-types, such as NamePlusRecord, RPNQuery, Query, RecordComposition and OtherInformation. --- 4.2.67 2013/09/19 Don't decode MAB as MARC. Just like we don't attempt to decode HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64. CCL: allow quoted terms for date ranges. YAZ-681 Introduce ccl_parser_qual_search. This function makes old function ccl_qual_search, from YAZ 2, available again. Add yaz_facet_list_to_wrbuf. YAZ-683 --- 4.2.66 2013/09/11 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if schema was given for search. YAZ-675 Add Solr date range searches. YAZ-621 --- 4.2.65 2013/08/22 ZOOM: another fix for record caching (introduced in YAZ 4.2.64). --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use) ISO2709/MARC parse most octet aligned records; not just those that are known to be ISO2709/MARC. This makes ZOOM and yaz-client MARC parse more records instead of just dumping as is. YAZ-670 ZOOM: proper caching for variations of record schema. YAZ-671 Solr: Check for enging / and perhaps commands (select/term) YAZ-651 --- 4.2.63 2013/07/17 Add yaz_strcmp_null --- 4.2.62 2013/07/11 New utility z_get_HTTP_Response_details - an extended version of z_get_HTTP_Response. New utility yaz_url_get_error which returns error message of last failed yaz_url_exec call. yaz-url and url functions: allow max HTTP redirects to be controlled. New functions yaz_file_glob2, yaz_xml_include_glob. These functions takes a flags parameter, which, for now only controls whether to fail inclusion of a non-existing file (without glob pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST. --- 4.2.61 2013/06/20 For MARC XML parsing, allow record without leader. A fake/default leader is inserted and a warning is tagged with the record. ICU: fix leak in in icu_iter_get_org_info. --- 4.2.60 2013/06/14 ICU: fix bug in icu_iter_get_org_info (un-init variable). --- 4.2.59 2013/06/11 Implement z_HTTP_header_remove. --- 4.2.58 2013/06/11 ICU: Disallow 0 ptrs for some ICU string utilities. ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info: returns original tokens (before normalization). CCL: avoid z39.58/regex truncation when not needed. Apply only the conversion of those masks, when absolutely necessary. CCL: configurable masking character - @mask. Default masking character is # for CCL. HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and full response anyway, so a Transfer-Encoding header will obstruct the response. --- 4.2.57 2013/05/15 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when picking a socket. Problem is that some systems has IPV6 support, but we can't create sockets for them, so we pick AF_UNSPEC first. HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response use content_len to determine resulting Content-Length in HTTP response and NOT Content-Length supplied in headers by user. z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than z_HTTP_header_add, to avoid having two Authorization headers by mistake. Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no content-length. Fix yaz_base64decode to use proper signed. Problem occurred on platforms with big endian and unsigned char (by default). --- 4.2.56 2013/04/26 Fix yaz-client connect (crash in 4.2.55). --- 4.2.55 2013/04/26 Fix proxy/host problem for ZOOM that could occur if unix sockets was in use. New Debian package libyaz4-dbg. Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye differently in tcpip_close. --- 4.2.54 2013/04/17 Windows installer of YAZ includes YAZ4J as a component. CQL: allow "extra terms" again, by default. Thus, the CQL parser accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51 and earlier. CQL parser may operate in strict mode where queries not conforming to the standard BNF are rejected (syntax error). Whether the CQL parser operates in strict mode is controlled with cql_parser_strict . Strict mode enabled with option -S for utilities cql2pqf and cql2xcql . yaz-ztest: returns OPACXML records for syntax=XML and element set=OP. --- 4.2.53 2013/04/10 New charset, MARC-8c, which is like MARC-8 but allows control characters 0x01 through 0x1F, except ESC to be passed through verbatim. Fix a problem with duplicate sub field character in MARC output. Problem happened only when output was MARC-8 encoded. --- 4.2.52 2013/04/03 yaz-ztest: Use hash for fake hit count. Before, random number was used. This is problematic for unit tests using yaz-ztest. This patch also makes a hash for CQL queries. For RPN, any term with a leading digit will be treated as pseudu hit count (to force any particular hit count by a client). yaz-ztest: return unique MARC dummy records. Beyond record offset 24, the author surname is patched with offset to make all records unique. COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending on system wide default (/proc/sys/net/ipv6/bindv6only). @4 binds to IPV4 only. @6 binds to IPV6 only. Update CQL API documentation a bit CQL: don't accept extra terms for queries. Makes the CQL parser stricly conformant to the standard. --- 4.2.51 2013/02/12 GFS: scan handler gets extra_args from request and may return extra response data . That's for SRU only. Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob. --- 4.2.50 2013/01/30 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC. OPACXML: sync spelling of availabilityDate in XML to that of Schema opaxxml.xsd. The schema had the correct spelling of this member always. The ASN.1 was mis-spelled and still is (API change) - we are not changing this. However, the OPAC to XML conversion had yet *another* typo. GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval element. New function, z_ext_record_oid_nmem, which is similar to z_ext_record_oid but takes NMEM rather than ODR --- 4.2.49 2013/01/18 ICU: New conversion element 'join' which joins tokens into one with a custom character given by rule attribute. --- 4.2.48 2013/01/10 New GFS search member: present_number. This is a hint to the search handler how many records are going to be fetched immediately following search. There's no guarantee that it's going to be the case, since it depends on hit count (for Z39.50 piggyback) and whether errors turn up. Make a few functions static (private). The functions getbyte_stream, ungetbyte_stream and yaz_gets are now private. They were never declared in a header file. yaz-marcdump: exit(5) for serious decoding errors ISO2709 decoding: be more picky WRT header GFS: bail out of fetch if last_in_set is set. Until now, last_in_set, was only used as to indicate that next-result-set-position should be set to zero. http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position Based on patch from Ashley Sanders. Make some functions static/private in PQF parsing. Those functions were never declared in a public header and so should not be in use by applications based on YAZ. --- 4.2.47 2012/11/23 ZOOM: special options to control APDU logging. Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable logging of APDUs until "saveAPDU" option is set again. If logging is already enabled the effect is that current APDU buffer is cleared. Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables logging (default behavior on new connection). The APDUs sent/received can be obtained by using Using ZOOM_connection_option_get(c, "APDU") or ZOOM_connection_option_getl(c, "APDU", &l). GFS: relay implementation_version from backend From 3.0.40 and later, implementation_version from backend was not used in init response at all. --- 4.2.46 2012/11/15 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking mode at all. Probably never did. Make a new version of ztest.pem that, at least, is not expired. --- 4.2.45 2012/11/13 Fix description of CCL directive 'case'. More tight checking of form arguments (yaz_uri_to_array). Makes YAZ better at rejecting big and/or bad POSTs. SRU decoding does not report more than up to 10 invalid arguments. rpn2cql: less quotes in generated terms. Semantics unchanged, but it's prettier this way. --- 4.2.44 2012/10/25 New utility yaz_decode_init_diag. Defined in proto.h. Allow HTTP protocol on unix local socket. Also Z39.50 database may be given for unix local socket. The COMSTACK string for doing so is: unix:: Examples: unix:/myfile:tcp:localhost:9999/mybase unix:/myfile:localhost:9999/mybase unix:/myfile:http://fakehost/mybase debian: Use dpkg-buildflags in build process. --- 4.2.43 2012/10/19 ZOOM C: don't trust recordPosition always. Some servers, such as IGI global's SRU service uses a recordPosition scheme starting from zero. First record's position should be one according to the standard. --- 4.2.42 2012/10/18 Allow more namespaces for SRU. This is to allow, for example, an incorrect namespace returned from server http://services.igi-global.com/sru . Minor fixes for compilation on Windows. --- 4.2.41 2012/10/11 daemon: log total number of bad signals from child on stop so that it is more easy to spot problems with child worker processes. retrieval: empty backend name attribute omits element set from being used in retrieval. --- 4.2.40 2012/10/04 Implement Solr sort strategy "solr", similar to sru11 sorting. This will implement the correct parameters on Solr requst to do native sorting. --- 4.2.39 2012/09/28 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic string returned. MARC: Extra/missing indicator handled for MARCXML. The indicator length is given in header and is the same for the whole record. If attributes ind1, ind2 are missing, then content character defaults to blank. Extra indicator attributes (beyond) indicator length are treated as an error. Reformat: delete trailing whitespace --- 4.2.38 2012/09/17 MARC: fix non-ASCII characters for leader. This is to ensure we can generate XML in UTF-8. CCL: new special attribute s=ag . Almost s=pw,al but preserves words in one node with structure word. --- 4.2.37 2012/09/04 yaz-json-parse: JSON output may be pretty printed by using option -p twice. Increase default value of max message for Z39.50 Init for GFS, ZOOM and yaz-client. Old value was 1 MB. New value is 64 MB. --- 4.2.36 2012/08/22 yaz-client: don't display bogus records from SRU servers. Some SRU servers return more records than given by *maximumRecords*. Skipping those in display! record_render: simplify buffer return handling and fix at least one bad memory reference, that broke the test_embed_record sometimes. Allow http://user:pass@host notation for yaz_url_exec. zoomsh: allow shell command to be executed. Via the system(3) call. yaz_poll: Allow num_fds == 0 yaz-client: fix bad encoding of "itemorder item". The itemorder item - command forgot to use length of encoded Item Request package. Error present since YAZ 3. yaz-ztest: fix bad usage of session handle. Bug was introduced when result sets were saved (271a9c83). SRU recordPacking: guess record packing in response rather than looking at the recordPacking element which, OF COURSE, changed semantics in SRU 2.0. Decode SRU 2.0 responses. The official namespace for responses, according to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse . nature.com's server, however, usee namespace http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason we are now using a glob-expr to match up the namespace. ZOOM C and yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know. I can not find a single real example showing the "real" namespace in the documentation from OASIS. The namespace for requests is different from responses, but this is not added to YAZ yet, when we don't encode them yet. --- 4.2.35 2012/06/26 zoom/record_render: add support for Base64 decoding fo MARC records within XML element. For example: "xml; charset=marc-8; base64=/my/text()" which will decode base64 + ISO2709 marc-8 encoded material from text node under /my . --- 4.2.34 2012/06/07 Add missing definitions ZOOM_resultset_get_facet_field_by_index and ZOOM_resultset_facets_names. zoom: fix bad free for ZOOM_connect - happened when ZOOM connection options was in use. Change APDU dump printing to avoid long leading blanks. For levels 16 or larger the level is shown and the indentation is truncated but recursed with modula 8. This makes it still reasonable easy to read - even for nested BER dumps. Fix bug completeBER_n WRT too nested BER. Function completeBER_n could return 0 (incomplete package) in case where the BER package was considered too nested (return value of -2). dumpber: lines of level 15 are not indented further. Two spaces per indentation; indentation 15 or more is indented to a fixed indentation and augmented with a level= indication. zoomsh: increase max size of command+args GFS: No limit in RPN buf size in CQL to RPN conversion. --- 4.2.33 2012/05/09 New function for daemon utility, yaz_daemon_stop . Makes yaz_srw_sortkeys_to_sort_spec public on Windows. --- 4.2.32 2012/04/25 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure --- 4.2.31 2012/04/23 YAZ daemon utility relays SIGUSR1 to child process. ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/ would result in en empty database list - which in turn would result in encoding failure for search. Fix reading beyond string in yaz_sort_spec. --- 4.2.30 2012/04/11 Add two new SRU diagnostics: 236: Access to specified database denied 1015: Init/AC: Maximum number of simultaneous sessions for Userid Document the very useful ZOOM-C option "apdulog". CQL to RPN: term may be passed through verbatim. This is enabled with truncation.cql . The assumption being that the term is already CQL. --- 4.2.29 2012/03/20 record_conv: leader spec may be given for marc element. The leader spec is given as attribute leaderspec for element marc. For example to convert a MARC21 record from MARC-8 to UTF-8: record_conv: allow user-XSLT params. For example: record_conv: fix error handling for missing marc charsets. CQL: fix extra terms in wrong order. --- 4.2.28 2012/03/06 record_conv: modify new API for conversion types. The conversion types may be passed in new functions yaz_record_conv_configure_t and yaz_retrieval_configure_t. Removing yaz_record_conv_add_type . Avoid mixed statement/variable declare; fixes compilation with Visual Studio. --- 4.2.27 2012/02/28 Add non-standard SRU diagnostic: 235: "Database does not exist". Couldn't live without it. HTTP 404: "Not found" is just so anonymous. Update SRU to Bib-1 diagnostic maps accordingly. CCL: add two new diagnostics for unsupported masking. The new diagnostics are: "Embedded truncation not supported" and "Single charcacter mask not supported". --- 4.2.26 2012/02/23 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25. --- 4.2.25 2012/01/11 Build YAZ for Ubuntu Oneiric. CCL: allow parantheses for proximity operands. For example CCL query (a) % (b) is now allowed. GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is marked dead, rather then being destroyed. If not, the session memory is being free'd before the search/scan handler is finished. Also destroy 'request' memory in request_release rather than in various places, which resulted in leaks from time to time. --- 4.2.24 2011/12/21 cql_sortby_to_sortkeys: honor sort prefix. RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's SRU server returns 0 hits on ISSN searches unless a CQL term is quoted. The rpn2cql family of functions now always returns quoted CQL terms. Fix CQL to CCL conversion for multiple terms. Add two test cases as well. --- 4.2.23 2011/12/15 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in sequence is treated as one. For example, &&a=b&&&c& is identical to a=b&c= . --- 4.2.22 2011/12/05 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save APDUs for a connection to a WRBUF. --- 4.2.21 2011/11/23 Fix cql_sortby_to_sortkeys. Completely broken before. Make CCL's @truncation work again. --- 4.2.20 2011/11/09 New ZOOM connection setting: tproxy. It's like proxy, but does not set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used to set resolved address + port for a connection outside ZOOM itself. Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it. --- 4.2.19 2011/11/07 Fix uninitialized variable in Solr spell support (could cause SEGV for SRU response decoding). Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass back-end's addinfo through into the ZOOM response addinfo. When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo, they are separated by a colon and a space rather than simply concatenated. --- 4.2.18 2011/10/28 Add support for Solr spell-checking/suggestions through ZOOM. If a Solr target has been configured correctly for spelling-checking and suggestions, these will now be returned on the ResultSet option "suggestions". zoomsh has been extended to show this with the cmd suggestions. --- 4.2.17 2011/09/28 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape with a flag whether to substitute escape sequences or not. --- 4.2.16 2011/09/22 Fix nmem_strsplit_escape to substitute escape char properly. New option for zoomsh -e , which makes it abort on first error and return process exit code to indicate success/failure. YAZ options utility supports special option -- which makes all it treat all following arguments as non-options. --- 4.2.15 2011/09/16 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not searched if absolute filename is given. Fix conv_xslt() error-reporting when stylesheet is not found. (The value of fullpath is meaningless in this situation.) --- 4.2.14 2011/09/07 Fix problem in CQL sort node creation: un-initialized memory. New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby depending on whether Type-1 or CQL is actually sent to the target. New sortspec utilities: yaz_srw_sortkeys_to_sort_spec, yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql. rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z will make it possible to use both single-character mask (#) and wildcard (?) in CCL . Throw diagnostic for left truncation because that is not supported by Solr. --- 4.2.13 2011/09/01 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special cases using escapes (\-sequences) and masking. PQF parse fix: A trailing backslash followed by end-of-string (\0) would result in a read one byte beyond string. rpn2ccl may use Z39.50 masking for terms (t=z). ICU check fix. Don't include library -lCrun on Solaris, unless present. ICU check fix: Use --cppflags-searchpath to determine ICU include files; not --cppflags (which seeems like an error in icu-config). --- 4.2.12 2011/08/27 RPM package only cql2ccl: fix conversion of terms: operator characters were not quoted/escaped. --- 4.2.11 2011/08/25 RPM package only ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the CCL parser will map both # and ? to their regular expression quivalents (. and .*). rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting of reserved CQL characters. cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as is, so that they are passed through. --- 4.2.10 2011/08/24 ZOOM SRU mode: more aggressive re-connect. Private function prox_unit_name() renamed to yaz_prox_unit_name() and made available as a utility function, declared in rpn2cql_structure() supports proximity nodes (except that the Type-1 proximity node's "exclusion" binary is ignored, as there is no way to express that in CQL). Fixes bug #4564. --- 4.2.9 2011/08/18 Fix SEGV that could occur if set command of zoomsh was given without value (2nd argument). Fix SEGV that could occur if unsupported transport was given for COMSTACK - say https (when SSL was unavailable). Build yaz-url on Windows too. --- 4.2.8 2011/08/11 New utility to get web content. Header is url.h. A command line tool yaz-url is part of the distribution and packages. Fixes for SSL COMSTACK (when gnutls is in use). New functions yaz_base64{encode,decode}. Header is base64.h. --- 4.2.7 2011/08/03 ZOOM C includes HTTP response buffer as additional info if it fails to decode the SRU response. Make wrbuf_json_puts available. --- 4.2.6 2011/07/28 zoom: throw diagnostic for invalid value for option "sru". Before a bad SRU request was sent. Adding new utility wrbuf_vp_puts. Add cclxmlconfig.obj to win/makefile. It was missing completely. --- 4.2.5 2011/07/21 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP). Fix a bug in handling of cookies. Fix a bug that would occur if proxy + redirect was used at the same time. MARC line mode decoding: be less picky about length given - first 5 digits of header that is. CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function). Changes to decoding of SRU records: a record with recordPacking=xml is modified with a new root element if the recordData contains multiple children elements. This is to make the record XML parseable afterwards. RPN to Solr conversion: encode special characters. Generic Frontend Server: fix uinitialized member, stepSize. --- 4.2.4 2011/06/21 Fix a bug in SRU decoding of records.. The database records stored had un-initialized memory, but it would only be seen with yaz_record_render and type_spec="ext" . Fix a bug in ccl_qual_dup introduced in 4.2.3. --- 4.2.3 2011/06/17 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset. --- 4.2.2 2011/06/10 Add new utilities to convert from CQL to CCL . These utilities have prefix cql_to_ccl defined in cql.h. Defensive coding for an off-by-one bug in ucol_getSortKey. This could lead to memory heap corruptions when ICU utilities were in use. --- 4.2.1 2011/06/07 Make compilation work without Libxml2. yaz-client: remove redundant blanks in display of searchResult-1 term hit counts. --- 4.2.0 2011/05/18 CQL: parse CQL sortby spec. The resulting sort spec is stored in the resulting CQL node (tree) in a new node CQL_NODE_SORT. CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend server to only consider srw_sortkeys and support both SRU 1.1 and 1.2. Note that the CQL sortby spec is only converted when the GFS is already converting from CQL to RPN (cql2rpn element). New function nmem_strsplitx. This is like nmem_strsplit but allows us to specify whether to collapse delimitors or not. The existing nmem_strsplit do collapse (collapse parameter = 1). Windows installer: For NSIS, set InstallDir depending on x86/x64. Rename internal func yaz_use_attribute_create. While non-static, this function is not declared in a public header. --- 4.1.7 2011/03/15 Add -lCrun when linking with ICU on Solaris. More quicks character set conversions for OPAC records. --- 4.1.6 2011/03/10 fix problem with record_render: records were converted (character set wise) even if no charset was given. Problem introduced in YAZ 4.1.5. --- 4.1.5 2011/03/08 SRU: add methods for handling DADS SRU-proxy facets. Separate OPAC record character set for ZOOM_record. yaz_record_render allows a character set given as charset=from/opacfrom,to where 'from' is the character set of a bibliographic record, 'opacfrom' is character set of OPAC record and 'to' is the target character set. --- 4.1.4 2011/02/21 yaz-client: show may XML format records. Command show followed by 'format' will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory function. src/stemmer.c: Avoid using unnamed union. It is not supported by some older C compilers. For PHPYAZ: set YAZVERSION, not YAZ_VERSION. --- 4.1.3 2011/01/27 Update yaz.spec to operate on both SLES11 / Centos 5.5. RPM: Release includes 'indexdata' name. Use indexdata in release name so this package can be distinguished from other vendors. yaz-config: Use exec_prefix, libdir, includedir . Use these variables as determined by configure yaz-config: set YAZ_VERSION env. php_yaz relies on it. GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler returns no error and no record, the present request is considered partial (only a subset of the records could be returned by backend), and so it is appropriate to set Present Status to partial-4. --- 4.1.2 2010/11/02 Move yaz-config man pages to section 1. More documentation about Solr. tcp comstack: change behavior for @-specs (anyaddr). @ listens on AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers. Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6 peers on some Linux systems. However, in general that does not work so YAZ can not rely on that to work. Debian changed behavior in this respect from Debian lenny to Debian squeeze (still testing as of Oct 2010). Refer to: http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html zoomsh: remove "debugging" output. Was added by mistake in 4.1.0. --- 4.1.1 2010/10/05 Fix yaz-config output: echo_source not set correctly by configure. --- 4.1.0 2010/10/05 Solr Web Service support for yaz-client and ZOOM. Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 . --- 4.0.12 2010/08/17 Z39.50 facet support. Facet specifications are passed for search in other-information with ASN.1 as defined in facet.asn and OID .10.1000.81.5 . Facets are expressed as an Attribute list as known from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type 3 is limit (number of entries to get in response). yaz-ztest returns dummy facets if a client asks for them. --- 4.0.11 2010/07/09 CCL fixes: bug 2895 and bug 3539. GR1-display: add comma in display - was removed by mistake in version 4.0.0. Windows installer: bundle MSVCP90.dll - used by icuuc42.dll. SRU: Merge cookies on HTTP redirects (Giannis Kosmas ). --- 4.0.10 2010/06/18 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a result set from a connection. The result set will be on its own thereafter; no operations on it will perform retrievals from a target. Only cached copies are returned. ZOOM C:fix case for HTTP servers responding with Connection:close. Ensure that if there is a current task it is resumed (like fetching more records in a result set) . Bug #3484. PQF parser: use odr_atoi for Odr_int (not atoi) Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute values that contain any non-digits are treated as string attributes (previously decoding only checked for leading character ([0-9]). PQF encoding: attribute string values are not surrounded by double-quotes. --- 4.0.9 2010/05/21 New utility for managing threads - thread_create.h. Add socket pipe utility - spipe.h. The socket pipe has same purpose as Unix pipe . Unfortunately Windows pipes do not work on select/poll - but YAZ' implementation do. Fixes for yaz_cond-functions on Windows 7. DLL export more symbols. zoomsh: show record do NOT render opac. Remove *.la files from Debian and RPM packages. --- 4.0.8 2010/05/11 Debian package libyaz-dev depends on libgnutls-dev again (was removed in YAZ 4.0.6, but due to Libtool it is still needed even though yaz-config do not list libgnutls libs). ZOOM: Use only one WRBUF for returning string results for ZOOM_resultset. Reduces memory usage for ZOOM in general. ZOOM: ZOOM_connection do not use a shared pointer to ZOOM_resultset after ZOOM_resultset is destructed by user. Reverts to YAZ 4.0.4 behavior. --- 4.0.7 2010/05/04 record-conv: fix problem with at least one XSL conversion - due to probably incorrect usage of XML XSL documents. --- 4.0.6 2010/04/29 Fix yaz-config for static mode and the use of SSL (gnutls). --- 4.0.5 2010/04/29 Forward decl timeval struct in mutex.h and gettimeofday.h. yaz-config: fix 'static' mode linking. --- 4.0.4 2010/04/28 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These are wrappers for pthreads or Windows. For Windows these are put in a separate DLL: yaz_cond4. libyaz.la (whole source) is compiled with thread. If thread support is enabled enabled, all source of YAZ is compiled with treading support. This allows core utilities such as yaz_log to use thread facilities. Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using thread utilities. This commit moves mutex utilities (mutex.c) from libyaz_server.la to libyaz.la. yaz-json-parse displays leading text until error. --- 4.0.3 2010/04/09 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on patch from Giannis Kosmas. SRU: no longer URL encode SRU database. The URL for an SRU server is a URL and such is alreeady encoded - at least when given with leading http:// or https://. This reverts behavior to YAZ 3.0.50. Support for new MARC XML notation TurboMARC which like MARCXML is a complete representation of MARC/ISO2709.. This one, however, is more compact and allows for faster processing with XSLT. TurboMARC can be used in the marcdisp.h API, from the yaz-marcdump utility and from the API of ZOOM C. yaz-ztest can be configured - via the database - to perform certain delays when it performs operations search, present and single record fetch. This allows testers to make yaz-ztest act as a real or even slow Z39.50 server. Refer to the yaz-ztest man pages for details. --- 4.0.2 2010/03/09 wrbuf_destroy allows NULL WRBUF passed to it. Fix CCL qualifier aliases (did not work since YAZ 2.1.56). Add ZOOM_connection_close. No fixed size buffers for ZOOM shell - bug #3257. tstodr: make it work on s390 platform. New icu iterator-functions. The new icu_iter-functions makes it possible to use ICU chains from many threads. yaz-client: better syntax check for show command. --- 4.0.1 2010/01/26 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to yaz/file_glob.h. New simple local-file XML include facility which allows file glob-patterns. Refer to yaz/xml_include.h. Utility yaz-json-parse which parses JSON and demonstrates the JSON parser API. ZOOM_record_get supports new parameter "format" which makes it format XML record content. Fix JSON parser WRT start symbol. The start grammar symbol (referred to as JSONText in ECMA-262) is JSONValue, not JSONObject. --- 4.0.0 2010/01/20 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9). Older versions of YAZ was compiled with Visual Studio 6.0 (1998). Update so/DLL to version 4. Windows version builds YAZ4.DLL. POSIX/Unix builds .so with major version 4. Remove old LOG_-defines from log.h. They have been obsolete and undefined by default for the last 5 years. Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series. GFS: Remove socket (int *fd) from search_rr handler. The socket descriptor ptr is a facility that allowed a search handler to supply a socket which would serve as a callback - when search was complete. This facility has now been in use for years. COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now returns 'const char *' rather than 'char *. The returned string is read-only and should not be modified by applications. COMSTACK cs_close is now a void function - it no longer returns int. No applications check for the value and the implementations has always returned 0. ZOOM: use size_t for scan hit counts and str size. Functions ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that occ (hit count) and len (string length) are now of type size_t pointer rather than int pointer. This is to be able to represent large hit counts and to also just to use the proper type for string length (strlen result). New JSON parser. Refer to include/yaz/json.h . WRBUF API changes.. For size parameters for WRBUF size_t is now used .. Used to be int in some cases. Many wrbuf_-functions used to return an int indicating some length.. These return values were never used. And so they are now void. ODR: odr_malloc, odr_total now takes size_t for size. clone_z_type: fix leak; occurred for encoding failures. --- 3.0.52 2009/12/03 tcpip comstack: fix use of uinitialized variable in cs_straddr. This bug was introduced in 3.0.51. --- 3.0.51 2009/12/02 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris. tcpip comstack: fix leak for getaddrinfo. Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API. Decoding of SRU "path" database is performed by private function yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy. yaz-client: honor base command for SRU. Change when database setting is applied for SRU and ensure it is kept when a connection is reset. Change also the way errors are displayed or SRU (decoding of packages). --- 3.0.50 2009/11/02 Add support for extra request / response data for SRU codecs and GFS. The Z_SRW_PDU structure has two new members extraResponseData_{buf,len} for extra data response buffer and length. For the GFS, both request and response data (XML) is carried in extra_args and extra_response_data for the search handler. Patch by Ko van der Sloot. ZOOM: For queries that cannot be converted to the specified rpnCharset, ZOOM now returns a diagnostic on the client-side ('invalid query' / 10010). This fixes bug #2113. yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that cmdfile included a 'quit' command that would result in a memory violation. --- 3.0.49 2009/10/01 Make a number of functions defined in xmlquery.c static. These have never been declared in a public header file (yaz/xmlquery.h) and was made public by mistake. Improve speed of character conversions (iconv utilities). This makes conversions from MARC-8 faster. ZOOM_record_get returns 0 pointer if a MARC record can not be decoded - unless type desired is "raw". This will prevent type "xml" from returning ISO2709 .. Which obviously can not be XML parsed. Fix memory leak in ZOOM that would occur if option apdulog was used on a re-used connection. Frontend server logs HTTP requests. Frontend server now sends Z39.50 close when it times out (sesssion has been idle for too long). Versions 2.0.30 and earlier also sent close. But due to a mistake this was disabled in all versions after that, i.e. the server would just close the socket immediately. yaz-client emits a better message when receiving an unrecognised userInformationField. Skip zero-length subfields when decoding ISO2709. This rare case happens if a record has two FS characters in a sequence. Without this patch there would be a reference beyond char array in using_code_len fragments in marcdisp.c. Fix yaz-marcdump error that would occur if option -n was used (bug #3028). --- 3.0.48 2009/08/28 The show command offered by the zoomsh command now takes a 3d optional parameter type which is what is passed to ZOOM_record. If the type argument is omitted, "render" is used. RPN to CQL conv may use USE string attributes (bug #2978). MarcXchange NS is now info:lc/xmlns/marcxchange-v1 . --- 3.0.47 2009/07/08 Function yaz_xml2query allows a diagnostic element in the PQF XML representation .. diagnostic@code and diagnostic@addinfo is diagnostic code and additional info respectively. The BER BOOLEAN is now the integral type Odr_bool which still happens to be an 'int'. The BER INTEGER which used to be a plain 'int' is now typedef'd to Odr_int. This is still an integral 'int', but it may be changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation, ASN-1 compiler as well as programs has been updated to use the new types. --- 3.0.46 2009/06/08 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously only the bibliographic record was rendered. For type=opac, an OPAC record is only returned if it is present. iconv: small fix for encoding of advancegreek. yaz-client: avoid double display of SRU/SRW records (bug #2798). yaz-client: option auto_reconnect=on really reconnects. yaz-client: fix bug #2770 - avoid length limit for auth parameters. server: avoid null ptr ref for for yaz_poll errors. build: fix RPM build for RHEL 5.3. comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350 --- 3.0.45 2009/03/31 Fixed bug #2709: TCP connect returns Invalid argument. Fixed compilation for mingw. Honor charset for raw records (ZOOM_record_get). Fixed use of errno for threaded mode that was seen on Solaris 10. Fixed argument passing with blanks in value for Windows Service. Disable YAZ' own log rotate by default (no 1 GB limit). The variable l_max_size which specifies the log file limit is set to 0 (DISABLED): This is due to the fact that YAZ is most often deployed using logrotate. Also YAZ can not perform log rotate because of unsufficient permissions (setuid). --- 3.0.44 2009/02/17 List supported encodings in man page for yaz-iconv. Fixed missing SSL libs for --libs output Re-established OID record syntax application-xml. Nobody should use it but we don't want to change soname because of this symbol being absent. --- 3.0.42 2009/02/02 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora. Added member named_result_sets for init handler struct for the GFS. This allows a server to disable named result sets. Removed OID record syntax application-xml. Added support for rule-based transliterator for ICU wrapper of YAZ. Fixed bug #1902: yaz-icu XML output. Make YAZ checks Emacs friendly. BITSTRING value shows value. Bug #2346. ISO2709 decoding: skip control characters from indicator data. Omit sort key by default in yaz-icu's output. Allow combined single char options (again) for YAZ' options function. Utility yaz-marcdump got option to display YAZ version (-V). Allow YAZ to use ICU 3.4. Added new ICU test case which illustrates removal of diacritics. --- 3.0.41 2008/12/29 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too. --- 3.0.40 2008/12/29 For configure, using option --without-xml2 also disables Libxslt/Libexslt support. Fixed bug #2352: yaz-marcdump crashes for certain record. Added man page 'bib1-attr' which includes list of common Bib-1 attributes. Added support for Danmarc2 to UTF-8 conversion. Added support for ISO5426 to UTF-8 conversion. zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of implementation version. Function yaz_version returns GIT SHA1 hash for parameter sha1_str. --- 3.0.38 2008/11/10 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously, ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received. ZOOM C now interprets databaseName option for ZOOM connection as path (SRU "database"). Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0. Fixed CCL to RPN/PQF conversion which could result in invalid PQF. Dummy Libxml2 types no longer defined in headers of YAZ'. Fixed memory violation for ZOOM C - could occur when SRU diagnostics was received. --- 3.0.36 2008/09/26 Various ODR chapter fixes. Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0. Added missing source for Windows compilation, mutex.c. Fixed compilation of YAZ for Visual Studio 2008. Bug #2256. For SRU connections in ZOOM all records up to "count" are now fetched. Fixed crash in generic frontend server (and yaz-ztest) which occurred in Windows due to bad error handling for Libxml2. Added facility for sending arbitrary records (ASN.1 any) using ZOOM C's Extended service update. Patch by Sam Reynolds. New options for ZOOM C's connection, logapdu which makes ZOOM log APDUs. --- 3.0.34 2008/06/18 YAZ uses GNU TLS without the OpenSSL compatibility wrapper. --- 3.0.32 2008/06/12 Fixed memory violation that could occur when decoding UTF-8. This bug was only present in 3.0.30 of YAZ. --- 3.0.30 2008/06/06 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but GNU TLS is used by default (if found). yaz-ztest returns OPAC records if a client asks for OPAC. Improved speed of MARC-8 encoding. Added support for lossy and loss-less MARC-8 encoding. Changed yaz_record_conv_record to be reentrant for XSLT conversions. Added new Windows Service wrapper (sc). yaz-client's itemorder command may now send a file. Fixed yaz-marcdump to allow the use of NS prefix for record element. Added new function yaz_log_xml_errors. Allow (but warn) unknown XML attributes in MARCXML parsing. Handle G1 sequneces in MARC-8 decoding. Bug #2115. The UTF-8 to MARC-8 conversion now uses a different set of characters for Greek symbols. Bug #2120. --- 3.0.26 2008/02/21 Added yaz_daemon (daemon.h). Fixed bug #2068: pkg-config trouble Fixed bug #395: ZOOM_record / OPAC record encoding problems. --- 3.0.24 2008/01/28 Document --with-xml2 option. Added OPAC XML XSD (etc/opacxml.xsd). Allow glob mask for name attribute in retrieval element for the generic frontend server's retrieval facility. Changed yaz_poll_poll to return yaz_poll_except for all returned events except POLLIN/POLLOUT. Fixed error handling in cs_listen. Bug #2037. --- 3.0.22 2008/01/20 Fixed version in yaz/yaz-version.h. Fixed bug #2027: Crash when closing connection. Changed configure so that ICU support is only enabled if only ICU and Libxml2 is available (because the ICU chain is XML based). --- 3.0.20 2008/01/15 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll, is built. Only this DLL depends on the ICU runtime. yaz-ziffy is no longer part of YAZ. It is distributed separately by Index Data because ziffy's license is GPL2 rather then 'Revised BSD'. Changed license of CCL module to 'Revised BSD'. After consultation with remaining members of the original EUROPAGATE consortium, we are re-issuing the CCL module without a separate license. The software was developed by Index Data as part of a research project. The special license was included to help feed usage information back to the project consortium to support project evaluation. At this time, the project consortium has long-since disbanded, and the majority of the original principals have retired. At the same time, we have significantly modified the software during the following years, to the point where very practically no original code remains. To simplify re-use of the software, we have contacted those members of the consortium who could be reached, and agreed to re-issue the module as a proper part of the YAZ package. Tcl scripts uses /usr/bin/tclsh as preferred shell. CQL closer to being version 1.2 compliant. CQL also allows free-form terms, such as 'title=a b', and thus, make the CQL parser more CCL-like and user-frendly. Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This bug could make Extended services handling crash in the ZOOM layer. This bug was only present in YAZ 3.0.18. --- 3.0.18 2007/12/19 ziffy uses YAZ' options rather than getopt; getopt is unavailable on some systems. yaz-marcdump reads and writes collection wrapped records. Handle OPAC for record conversion module. Fixes for ICU wrapper. Allow ICU libs to be controlled with --with-icu . --- 3.0.16 2007/11/12 Added yaz_poll which is a wrapper for select/poll. When poll is available and non-buggy, it is used, by yaz_poll . This allows more than 1024 sockets to be in use. Added ICU wrapper library which exposes ICU http://www.icu-project.org/ functionality through an XML based configuration (ICU chain). This system is useful for search facilities such as Pazpar2 and Zebra that needs to perform tokenization of indexed material. The ICU code in a separate library libyaz3_icu.a. Added HTTP tunnel facility for COMSTACK, bug #1752. This is a facility that allows a Web proxy, such as squid, to tunnel Z39.50 traffic. This facility is "transparent" to must applications using YAZ. It's enabled by using pseudo transport connect: followed by the proxy address, followed by command, then follwed by he regular "virtual" addresss. For example, connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager . More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778. --- 3.0.14 2007/09/21 Fixed bad memory reference in ZOOM_record - cuased by member not being initialized. This was a problem only in YAZ 3.0.12. Fixed bug in conversion from MARC to XML: Non-XML characters in control fields were not removed. Changed the way C code is generated from codetables.xml. Made a MARC-8 conversion trie for each characterSet section rather than codeTable. This is ensure the code can deal with G0/G1 sequences. Use of a newer version of codetables.xml from Larry Dixson, LOC. Bug #1464. --- 3.0.12 2007/09/12 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned from ZOOM_record_error). ZOOM C function ZOOM_record_get returns record schema for type="schema". Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests. Added new ZOOM C connection option 'sru_option' which specifies SRU version. Better SRW-to-Bib-1 diagnostic mapping. ZOOM C and yaz-client announces SRU version 1.2 by default. yaz-client 'sru' command may specifiy both SRU version and transport (SOAP, GET or POST). Fixed in yaz_sru_decode to allow other version than 1.1. --- 3.0.10 2007/08/22 Added support for SRU scan for ZOOM. Added support for the use of the older versions or Extended Service Update in ZOOM. To faciliate this, an option "updateVersion" may be set to the version , 1=first, 2=second, 3=third. The third version is what ZOOM C has used so far. And that, obviously, is the default. Added support for CCL queries in Z39.50 queries sent to the GFS (and therefore in Zebra and in SimpleServer-based applications). The new element in a GFS configuration file, if present, names a CCL qualifier file used to transform incoming CCL queries into Type-1 RPN, which is passed into the back-end search callback function. Added support for HTTP Basic authentication in clients: the SRU/W codec encodes the username/password elements of the PDU structure appropriately, and these may be set using the "user" and "password" options in ZOOM-C applications (the same options that are used for Z39.50 authentication). --- 3.0.8 2007/06/25 Fixed bug #1208: SSL appears to be broken in ZOOM. Fixed bug #1206: Libxml2 include path weirdness. Added oid_name_to_dotstring. Allow elementSetName to be specified for ZOOM C record update. Allow waitAction to be specified for ZOOM C based for Extended Services. Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record syntax OID. Bug introduced in YAZ 3 series. Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19. --- 3.0.6 2007/06/06 Fixed bug #1157: yaz-client does not read .yazclientrc from current directory. yaz-client now reads commands from file given by option -f if specified; then tries to read .yazclientrc in current directory. Failing that, it reads .yazclientrc from user's home directory. Added support for correlationInfo Note and ID for Record Update via ZOOM C. Added yaz-client command querycharset which specifies character set for query terms for Z39.50 RPN queries and Z39.50 Scan Requests (termListAndStartPoint). Charset ISO5428:1984 is an alias for ISO5428-1984. Implemented a way to perform scan in a result set using Z39.50. This is achieved by attaching the result set name in the characterInfo (type InternationalString) of OtherInformation in the Scan Request PDU. The result set is identified in the otherinformation by the new OID: USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set This allows for scan in result set and faceted search . Zebra did some of this in the APT term using attribute type 8 and value being result set. Using the OtherInformation approach for this is cleaner and easier to work with in proxies and the like. This facility can be used in yaz-client using new command setscan which takes a result set as first argument, start position (APT) as second. Changed decoding of SRU XML packed records to deal with servers that have recordData with XML data with multiple root nodes. Also make comparison for recordPacking case insensitive. Again, one server returns "XML" where others return "xml". For SRU responses allow Content-Type application/xml as well as text/xml. --- 3.0.4 2007/05/21 Fixed bug in character set conversion of BER strings. Bug introduced in 3.0.0. --- 3.0.2 2007/05/08 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int. For OID class, use oid_class consistently. Fixed external handling for SUTRS and Explain records (bug appeared in 3.0 series). Added partial support for ISO5428-1984, which is the "Greek alphabet coded character set for bibliographic information interchange". By Giannis Kosmas. Added documentation on new OID API. --- 3.0.0 2007/05/02 Changes to generic frontend server interface: added new member 'query_charset' for bend_initrequest structure. A backend init handler should set this member to its native character set for query terms. When defined, the frontend server logic will announce this character set to a client if the negotiationModel bit is set by the client. All server implementors are encouraged to specify this. If a backend server does not specify this a warning is issued using yaz_log(YLOG_WARN,..). Added CCL utility to remove terms (stop words) from resulting RPN tree. This is handled by functions with prefix ccl_stop_words_ . New ZOOM C option, "rpnCharset", which allows client-side conversion of terms in RPN queries. Clean-up the CCL API. Moved some internal structures from ccl.h to private header cclp.h. Changed ccl_parser_create so that a Bibset must be supplied. Removed tokenize API from ccl.h - including ccl_parser_find. This is replaced by ccl_parser_find_str which takes a string instead. Split YAZ library into two libs : libyaz.la and libyaz_server.la. libyaz.la is the core of YAZ except the generic frontend server and does not depend on POSIX threads anymore. libyaz_server.la is the generic frontend server facilities and uses POSIX thread functionality if available. The libyaz.la no longer depends on POSIX threads because the number of global structures is limited. NMEM no longer re-uses blocks between threads ; it simply free's memory immediately but allocates in "large" chunks as usual. We don't expect any performance penalties because of this. The yaz_log system is still using a global log_level so caution must be taken when modifying it with yaz_log_init_.. + yaz_log_mask_str. This, however, should not cause any trouble because these functions are called during initialization of application code anyway. `yaz-config --libs server` returns libs for server applications; `yaz-config --libs` returns libs for non-server applications. New OID database - with public definitions in oid_db.h. Removed old OID database including the head oid.h and definitions such as enum oid_value and struct oident. The new OID database uses the same string names as before but the 'protocol' is gone. There are now only two representations raw OID (int *) and string. Functions with prefix yaz_string_to_oid converts from string to OID; functions with prefix yaz_oid_to_string converts the other way. Change to emit_term() in CQL-to-PQF query translation: when a term has the /regexp relation modifier, do not process it for leading and trailing "^" and "*", which have quite different meanings in regular expressions. Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function write handlers no longer carries a 'last' parameter. This will make yaz_iconv flush "less" characters. A flush is performed by call to yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) . Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery removed, because function yaz_query_to_wrbuf does the same. API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out. Deprecated MARC utility functions removed. Changed prototype of yaz_marc_decode_buf: const char for result and size_t for rsize. Branch split: YAZ_2_1_55_branch --- 2.1.54 2007/03/16 Fix to ZOOM-C so that transparent reconnection is properly handled on connections that are in asynchronous mode. Fixed compilation on OpenBSD 4.0. Large strings in GRS-1 records are now properly displayed in yaz-client. Added character conversion support for "advancegreek"; based on patch from Giannis Kosmas. Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo sequence is met. Before the error was not set so it would be unknown. Adjust yaz-marcdump MARC reader so that it skips until record separator is read --- 2.1.52 2007/03/07 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll(). Note that ZOOM_event_sys_select() still has the limit due to the fixed-size fd_set structure used as a bitmask for the FDs to be selected on. Using ACX_PTHREAD macro to check for POSIX threads. Fixed have-vsnprintf check. --- 2.1.50 2007/02/23 Fixes for configure on BSD. Bug #900. Added snprintf/vsnprintf wrappers for systems that don't have limits (heavens forbid). Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was created before all previous tasks were completed and removed from the task queue, the new task could be removed by a mistake. Fixed bug #615: Document retrievalInfo facilities for Frontend Server. Implemented pass-through CQL-to-PQF conversions. Bug #861. Fixed bug #832: Problem with MARC/charset in yaz-client. Fixed bug #668: save command line history for yaz-client. Fixed bug #830: pkg-config support. --- 2.1.48 2007/01/23 Extended ZOOM result set options with two options that may be read by a client: resultSetStatus and presentStatus with values as specified for the ASN.1. See: http://www.loc.gov/z3950/agency/markup/04.html#Search-status Fixed bug #827: Using SSL fails on Debian etch. Fixed bug #826: Weird looking chars for set of MARC records. Implemented alternative Item Order package for ZOOM. If option "doc" is set, that is treated as an ItemOrder with itemRequest being an XML document external. The value of "doc" is the content. Extended the GFS search facility. New member of bend_search_rr 'estimated_hit_count' signals that hits is known to be an estmate (higher or lower than real hit count). New member 'partial_resultset' signals that the search was partial (hit count is lower or equal than real hit count). For Z39.50, the information is stored in resultSetStatus member of SearchResponse APDU. For SRU, the information is signalled via SRU diagnostic 59: "Result set created with valid partial results available". Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF. --- 2.1.46 2007/01/13 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers. Added ZOOM_connection_peek_event. Implemented Generic select hook for ZOOM (bug #803). This is achieved with the following new functions: ZOOM_event_nonblock, ZOOM_connection_process, ZOOM_connection_get_{socket,mask,timeout}, ZOOM_connection_fire_event_{timeout,socket}. The existing blocking event handler, ZOOM_event, is a wrapper for the + blocking ZOOM_event_sys_{poll,select}. Implemented function ccl_xml_config which parses XML version of CCL configuration (bug #798). Fixed bug #797: yaz_marc_write_xml does not honor character conversion. Added timings utility (yaz/timing.h) --- 2.1.44 2007/01/03 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as Libxml2 tree. Fixed bug #779: Rotation of apdu.log fails. Fixed for character set conversions: Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences. Honor G1 set in MARC-8 decoding. --- 2.1.42 2006/12/17 Fixed bug #775: char conversion does not handle Alternative UTF-8 sequences. Implemented function yaz_marc_read_line which parses MARC line format records. There is a wealth of formats out there. So far, this function reads line records produced by yaz_marc_write_line. yaz-marcdump's options -x, -X, -I, -e have been replaced with the more generic and easier to remember(!) options: -i format and -o format which specifies input format and output format respectively - where format is one of "marc", "marcxml", "line", "marcxchange". Added 'check only' option for MARC utilities. Option -n for yaz-marcdump does not print anything except warnings for records. For yaz-marcdump, added support for MARC split into files (-s) with a given chunk size (-C). Changed the SRU update structures and codecs to reflect the SRU pre 1.0 spec, at http://www.loc.gov/standards/sru/record-update/ This has changed the binary layout of the following structs: Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and bend_update_rr . Patch by Ko van der Sloot. Added GFS utility function bend_assoc_is_alive which returns 1 if association is still alive (client is connected); 0 otherwise (client closed connection). This allows busy servers to stop working for impatient clients. Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has been a separate piece of software. This version of ziffy has been modified to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2. Fixed bug #740: Handle SRU records referring to xmlns's outside recordData. Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved. Client code may now interrogate options such as "init_opt_sort" to find out whether the server claims to support various options. --- 2.1.40 2006/11/27 Added utilities yaz_{set,get}_esn to set/get element set name from record composition. Removed the build of libyazthread.la. The libyaz.so is the threaded version of YAZ and has been so since YAZ 2.1.10. Implemented ZOOM_record_error which returns error information for record (surrogate diagnostic). --- 2.1.38 2006/10/31 Updates for SRU Update by Ko van der Sloot: 1. Changed name from "operation" to "action" 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old versions in the code, marked as 'backward compatible'. 3. Added diagnostics for SRU Update. Fixed bug #709: Records are fetched in wrong format when tasks are queued. Fixed bug #707: CQL->RPN ignores lines with leading spaces. Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255. For GFS, fixed problem with SRU diagnostic 'First record position out of range' being issued for 0 hits. zoomtst10 part of Windows Build. --- 2.1.36 2006/10/13 Implemented yaz_filepath_comp which splits a path into file path components (required by Zebra 2.0.3+). Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a BSD inspired license until now so this should not have any real impact on anybody. See http://www.opensource.org/licenses/bsd-license.php Fixed bug #687: Missing log lines. Fixed bug #678: CQL to PQF translation does not preserve double-quote escaping. Fixed bug #689: SRU diagnostics to be added. Implemented new ZOOM function, ZOOM_connection_is_idle, which checks whether a connection is idle (no more work do do). --- 2.1.34 2006/10/04 Change type of optval from long to int for invocation of setsockopt with the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis. Added support for specifying the max log file size for the Generic Frontend Server. The size is given with option -r. --- 2.1.32 2006/09/21 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code. --- 2.1.30 2006/09/17 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced in YAZ 2.1.28. Fixed bug in Generic Frontend Server that could cause a server to stop accepting new connections. Bug only seen on dual CPU Windows 2003 server. For the generic frontend server, the maximum record size is used as maximum size of incoming packages (SRU + Z39.50). The value until was previously only used in Z39.50 Init negotiation and, later, in a session controlled sizes of records returned. This is controlled using -k option. It can be specified, per server, with element maximumrecordsize in YAZ' GFS XML config. --- 2.1.28 2006/09/04 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6 friendly now. Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV. New option for yaz-marcdump -lpos=value which allows setting a portion of MARC header to a certain value. Fixes for MARC generation when encoded as MARC-8 (bug 642, 643). ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 . --- 2.1.26 2006/08/15 Fixed problem with SRU mode type (soap, get, post) for yaz-client and ZOOM-C. Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626. --- 2.1.24 2006/08/08 Fixed MARC ISO2709 encoding routines to deal with character set conversion. Minor changes to GFS logging. Database included in search request log line. Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for cached/multiple records. Shared libraries are built by default on Unix+configure. Changed cql2pqf transformation to use a different evaluation order. The new order is: always, relation, structure, position, truncation, index and relationModifier. Old order was: always, relation, relationModifier, structure, index, position, truncation. Note that the the latter ones override former ones for identical attributes.. The new scheme means that it is possible to override any existing attribute with a relationModifier. And also that it is possible to override everything for the index rule (except the ones listed in relationModifier). No order is perfect but this one, we believe, covers more real cases.. The "always" should have been called "default", since the attributes there can be overridden with all the rest. For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the compilation phase, but also for yaz-config --cflags output. This allows us to have public headers with Libxml2 stuff in them . It should also, eventually, make Libxml2 checks redundant in packages using YAZ, such as yazproxy. --- 2.1.22 2006/06/15 Changed SRU update structure bend_update_rr so that SRU diagnostics are stored in uri, message and details.. Previously diagnostics were stored in errcode, errstring. Patch by Ko van der Sloot. Breaks binary compatibility.. but he's probably the only one affected, so. Added support for CCL, compiled on the client side, in ZOOM-C. This is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as input; the resulting query objects can be used for for searching with ZOOM_connection_search() and scanning with ZOOM_connection_scan1(). YAZ' configure searches for OpenSSL by default. SSL comstack uses SL_CTX_use_certificate_chain_file rather than SL_CTX_use_certificate_file. See http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html for more info. Thanks to Ko van der Sloot. --- 2.1.20 2006/06/02 Bug #600: SRU GET, POST support for yaz-client. Introduced command 'sru' which selects method SOAP/GET/POST. Allow missingValueAction to be specified for the sortspec string - function yaz_sort_spec. By default, the missing value action is null. Use ! to specify "abort". Use = followed by stringvalue to specify default value. Ensured that Present-handler (if defined) is called in GFS before any call to fetch-hhndler. This now includes piggy-backed presents as well as SRW/U searchRetrieve requests. Documentation for YAZ is now based on the Docbook XML/XSLT using xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ is no longer depending on jade/openjade or docbook-to-man scripts. PDF is no longer part of the distribution - but can optionally be made using DSSSL/jadetex or FOP. Added retrieval handling support in Generic Frontend Server to support conversion between MARC/XML as well as XSLTtransforms. See etc/yazgfs.xml for an example. Added Authentication support to Generic Frontend Server in SRU mode. Authentication using HTTP Basic is supported, as is the use of 'x-username' and 'x-password' parameters in the request itself. Added support for a new character set MARC8s identical to MARC8 except that it converts combined characters to single Unicode characters in the Latin-1 range (when possible). --- 2.1.18 2006/04/24 ASN.1 compiler 0.4: generates brief Doxygen file header for generated .h/.c files. Utility yaz_iconv now supports conversion to MARC-8. New facilities for the MARC module. The reading - and writing of content are separate methods for the yaz_marc_t handle. The following read functions are available: yaz_marc_read_iso2709 (Reads MARC in ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange format). Write functions have prefix yaz_marc_write_.. The existing utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still available. Removed support for OAI-MARC and simplexml (not the simplexml from PHP5). Added a new ZOOM event type ZOOM_EVENT_END which signals no more events to be returned for this connection. --- 2.1.16 2006/03/31 Allow multiple languages and charsets to be specified with yaz-client. Each item must be separated by comma (NO BLANKS). E.g. negcharset iso-8859-1,utf-8 Translation of proximity nodes from CQL into PQF now works. Moved to automake 1.8, 1.9. Added function yaz_log_set_handler which allows a log handler to be installed. This handler will be called for all log messages. Output to file is also produced; but that can be disabled by passing NULL fname to yaz_log_init_file. Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537. For SRW (including GFS), accept application/soap+xml as content-type for SOAP msg. For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&) produces NO stylesheet reference even if a default stylesheet is specified in GFS XML config. --- 2.1.14 2006/03/14 Updated Windows package to include yazd.dll + yazd.lib for the Development component. If the environment variable YAZ_LOG is set, then it is used as a string indicating the default level of logging to use if not overridden by calls to yaz_log_init() or yaz_log_init_level(). If it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is used as before. So, for example, to omit warnings from YAZ logging, export YAZ_LOG=-warn cql_transform() now map structure and other attributes before indexes, so that index-specific structures and other attributes can override defaults. So now a combination of mapping specifications such as: structure.* = 4=1 index.dc.date = 1=date-modified 4=5 does the right thing. cql_transform() now also respects the "always" mapping specification, which establishes an initial set of attributes to be used for all terms except where overridden by more specific attributes associated with the index, relation or modifier. Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies which mode to use; one of "post", "get" or "soap" (SRW, default). Fixes for yaz_iconv routines: changed trie-based character set conversions to use only non-negative values for bit fields due to Sun's C compiler not supporting negative values. Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8 sequences where not read correctly. Fix by Rustam Usmanov. Updated win/makefile to use options, settings which makes things compile with VS C 2005. --- 2.1.12 2006/02/01 Fixed bug in yaz_oi_update which used incorrect value for categoryValue. In ZOOM socket code, use select instead of poll on MacOSX. ZOOM-C now support client-side compilation of CQL into RPN that is sent to the server, enabling CQL to be used against all Z39.50 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a ZOOM_query object, and submit it using ZOOM_connection_search(). The CQL-to-RPN translation uses a configuration file, the name of which must be specified in the Connection's "cqlfile" option. ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1() function, which takes as its start-term parameter a ZOOM_query object (which may have had either CQL or RPN set into it). --- 2.1.10 2005/11/29 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the GFS to support this as well. Backend handler, bend_srw_update, does the update work. Code contributed by Ko van der Sloot. Allow retrieval of Search Result-1 information in ZOOM by the use of options that are attached to a result set. ZOOM documentation updated accordingly. Fixed bug #416: First/second comb characters not handled in the MARC-8 to UTF-8 conversion. Patch by Raj Patel. Added option -m to GFS to control formatting of timestamps in log file. Added 'exit' as synonym for 'quit' in yaz-client Added support for specifying SRW resultSetId + resultSetIdleTime in a Generic Frontend Server's search handler. Refer to include/yaz/backend.h for the new members. Patch by Ko van der Sloot. Added support for SRU POST. It is supported for content-type application/x-www-form-urlencoded only. Patch by Ko van der Sloot. Do not build the separate Multi-threaded (MT) library libyazthread.la. Instead make the library libyaz.la multi-threaded. Threading as a whole can still be disabled by configure option --disable-threads. Previosly, with older GLIBCs there were problems with MT libs under Apache. This has now been fixed a long time ago. Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded applications. CQL module modified to be case insensitive for relations/indexes/operations. Fixed bug in CQL transform code: incorrect value relationModifieder was used. Added 'show all' command for yaz-client which retrieves all results for last search. Added new yaz-client, xmles, which takes a (private) OID and a document to be sent as an extended service request. Describe new yaz-client commands wait_response and set_auto_wait. Increase TCP/IP listener backlog from 3 (which I am guessing was copied from the SunOS manual entry way back when) so SOMAXCONN, so that the socket will queue as many incoming connections as it's able to handle ongoing connections. In other words, it will never now refuse a connection that it would be able to handle merely because it's not got around to accepting() enough of the pending connections yet. This is the behaviour anyway under Linux, where the listen() argument is ignored; but not under BSD and on systems such as MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of YAZ-based servers should now be uniform across operating systems in this respect. yaz-marcdump uses 64-bit file access on some systems. This is enabled on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported. This allows yaz-marcdump to read large MARC batches (>2 GB). Modified all YAZ source files - except the source which is auto-generated by tools - to use spaces rather than TABS. Emacs/VIM trailer added to all source files. Add ZOOM_connection_option_getl() and ZOOM_options_getl(), corresponding to the existing *_setl() function. These allow option values containing arbitrary valuues. Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of ZOOM_resultset_sort() in new applications. Its behaviour is identical except that it returns an indicator of whether or not the sort criterion was accepted (0 for OK, -1 for invalid). --- 2.1.8 2005/06/07 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended MARC output rather than returning "new" buffer. yaz-client warns about unknown init options. Fixed bug #371: "options concurrentOperations ignores concurrentOperations" --- 2.1.6 2005/05/24 Added support for SRW sort in Generic Frontend Server. Patch by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds sortKeys - or NULL if none is provided. Fixed bug #307: It was impossible to specify indefinite/no timeout for ZOOM_event. Special timeout value -1 now means indefinite timeout (i.e. no timeout). Added support for multiple languages and charsets to be specified in ZOOM. Each charset/language is separated by a blank. If negotiation is in effect in init-response, Option "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false). Code based on patch by Vasiliy Osadchuk. Fixed bug #306: infinite recursion that occurred when calling yaz_log_level_init as the first call (before other log level or nmem_init calls) Fixed bug in scan handling in front end server: if preferred-Position-In- Response was non-present, a NULL pointer referece was performed. --- 2.1.4 2005/04/26 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are now defined for all those error codes. So instead of putting 109 in your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages are generated from a .csv - file. See src/bib1.csv and srw/srw.csv. Modified the yaz-marcdump utility to skip garbage bytes between MARC records in a file. Fixed bug - uninitialized memory - due to bad code for fix of bug #272. Program yaz-client now exits and produces an error message if multiple Z39.50 servers are specified on the command line (none or one allowed only). Program yaz-marcdump skips garbage bytes between ISO2709 records rather than abort. --- 2.1.2 2005/03/16 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes. Fixed bug #272: Preserve spacing for CCL terms. --- 2.1.0 2005/03/14 Added support for virtual hosts and multiple backend servers for the YAZ frontend server. The configution is XML based and support specificition of CQL to RPN mappings and explain information. See section "Virtual Hosts" in the YAZ manual. Extended OPAC display utility. OPAC display utility renders bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf to supplement yaz_marc_decode_wrbuf. Fixed a bug in MARC decoder that could caused it to crash for some invalid MARC records. More diagnostics and warnings where added in XML output (warnings, etc are stored in comments). --- 2.0.34 2005/02/08 Fixes for UNIX domain sockets. Bug #261. Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260. Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields. Added yaz_marc_subfield_str which defines subfield lead string which is used in YAZ_MARC_LINE format. Default string is blank+$. Added yaz_marc_endline_str which defines end of fields string used in YAZ_MARC_LINE format. Default string is newline. Experimental support for MarcXChange. This format can be produced by yaz-marcdump and is implemented in yaz_marc_decode - functions. http://www.bs.dk/standards/MarcXchange.xsd Added yaz-client commands scansize that sets maximum number of entries to be returned by scan. --- 2.0.32 2005/01/11 Added support for SRW scan in yaz-client and Generic Frontend Server. * Added whereInList member to SRW Scan Term. * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF. Fixed NMEM system to return aligned blocks on the smallest boundaries that are suitably aligned for all possible types on the particular architecture YAZ is being built for. --- 2.0.30 2005/01/04 Fixed numerious warnings that was issued with newer versions of GCC. Fixed NMEM system to return aligned blocks on 8 byte boundaries rather than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3 on Solaris. Make YAZ Generic Frontend Server slightly faster. Enhance (and reduce) logging for Generic Frontend Server. Revert YAZ log system so that it flushes every write operation by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240. Modified the YAZ logging system. The LOG level defines use YLOG_ prefix instead of LOG_, due to name clash with syslog(3). LOG_ are still present. New applications should define YAZ_USE_NEW_LOG=1 - this will effectively disable old definitions. --- 2.0.28 2004/11/09 Added yaz_log_time_format which specifies log format using strftime(3). Added yaz_log_module_level which returns mask for a module. Value is non-zero mask a if module is enabled; zero if disabled. * Fixed bug #148: CQL parser may leak. A few prototypes were changed in include/yaz/cql.h. Fixed bug #176: Dont throw diagnostics on empty SRU args. Fixed bug #175: surrogate diagnostics in SRW lacking NS. Fixed bug #172: RPM builds does not enable SSL. Doxyfile.in part of dist. Doxyfile generated by configure. Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd are given and the corresponding component does not exist. Extend CCL documentation in YAZ reference. Describe r=r. --- 2.0.26 2004/10/01 Fixed MARC->MARCXML conversion to properly deal with fields, subfields, indicators having non-ASCII characters. Fixed MARC->MARCXML conversion so that ASCII control characters except TAB,CR,LF are removed from resulting XML (XML 1.0 does not support these). Added YAZ GFS support for conversion from Z39.50 surrogate diagnostics to SRW surrogate diagnostics. Bug fix: YAZ GFS did not return schema in explainResponse. --- 2.0.25 2004/09/30 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures now converts recordSchema to elementSetName as well as schema URI. Fixed bug in COMSTACK that prevented HTTP request packages from being decoded properly. --- 2.0.24 2004/09/29 Added CCL facility r=r "range" which is similar to r=o "ordered" but does not require white-space before and after the dash in a range, e.g. x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980 iff r=o. Fixed a few AC_TRY_LINK configure tests that did not operate properly due to new GCC removing "redundant" code. Added yaz-client commands scanpos and scanstep that sets preferred position and step-size for scan. Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz. Added CCL utility ccl_qual_buf which parses one or more CCL spec lines in a buffer. Added CCL utility ccl_qual_line which adds CCL qualifier line consisting of name and value - ignoring empty lines and comments. On Windows, the debug DLL/import lib is now named yazd.{dll,lib}. Added odr_get_element_path which returns current element path for an ODR handle. This utility is useful in error handling or user-defined ODR_PRINT stream. Added ODR_PRINT utility odr_set_stream which is is a more generic alternative to odr_setprint. odr_set_stream takes a stream handle, pointer to a write function and pointer to close function. The close function - if non-NULL - will be called during odr_destroy. Fixed bug in CCL parser where truncation char was not removed from right side when truncation=both was in effect. Fixed CQL parser to use unsigned chars for isxxx from ctype.h due to VS.NET. --- 2.0.23 2004/08/11 Fix buffer overrun in CQL parser when dealing with proximity (%). Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8 to UTF-8/UCS conversion is now only based on codetables.xml. yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output. --- 2.0.22 2004/08/06 Add support for more "commit changes" in ZOOM (uses Extended Services). For yaz-client, command set_marcdump / -m dumps SUTRS/XML/.. records as well. Yet another small fix for configure of SSL. --- 2.0.21 2004/05/14 Fix SSL libs for configure when --with-openssl=DIR is given. --- 2.0.20 2004/05/10 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook). SSL comstack now uses yaz.pem certificate file on server side by default. Certificate filename can be configured by calling comstack function cs_set_ssl_certificate_file before cs_bind is used. Fix bug regarding multiple calls to ZOOM_connection_connect. Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack. Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind, tcpip_rcvconnect instead. This allows user to set custom SSL_CTX. ZOOM now allows inspection of X509 peer certificate for verification. The X509 buffer is retrived by reading ZOOM option "sslPeerCert". Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and all programs have too (yaz-ztest, yaz-client, zoom..). May not be as "modular" but it simplifies things. Added cs_get_peer_certificate to that returns peer X509 PEM. Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns NULL if SSL is unavailable. Documentation about MARC decoding tools. Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson. --- 2.0.19 2004/03/30 Rename CHANGELOG to NEWS to follow GNU style packing. Fix bug with missing initialization of member in init_diagnostics. This bug affects threaded version of GFS server. --- 2.0.18 2004/03/20 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with Zebra symbol. Ensure zlib.dll is packed with Windows install. --- 2.0.17 2004/03/17 Fix encoding of xsd:string to use text instead of CDATA. Fix endless loop in CQL parser with unbalanced ". Use a more compact way to store MARC-8 conversion tables. --- 2.0.16 2004/03/16 Debian only Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to UCS4 / UCS4LE. Update CQL parser to use new CQL 1.1 modifiers for booleans and relations. Add CQL test cases. --- 2.0.15 2004/03/01 Another fix for decoding of XML packed records. --- 2.0.14 2004/02/25 Fixes for Chunked encoding. White space not ignored after length spec. Update NS and use default NS for SRW diagnostic elements. --- 2.0.13 2004/02/23 Implement ZOOM_resultset_cache_reset which resets record cache. Implement ZOOM_resultset_sort which sorts a result set. Implement chunked HTTP transfer. For SSL, use -lssl -lcrypto on systems that don't have pkg-config. --- 2.0.12 2004/02/16 Added member 'schema' to bend_explain_rr structure so that backend can specify explain record identifier. Defaults to Zeerex 2.0. Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11. --- 2.0.11 2004/02/16 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead of code. Added init command for yaz-client which sends "extra" init request. Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39. Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail. Make ZOOM error code for "invalid query". Fixed compilation for SSL which wasn't properly enabled for all platforms. --- 2.0.10 2004/02/05 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of YAZ required. * SRW/SRU 1.1 updates. Diagnostic code now a URI. Added option -p to make Generic Frontend Server to write PID file. Added option -D to put Generic Frontend Server in background on its own. Make ZOOM C recognize option "password". If unset, "pass" is used (for backwards compatibility). Fixed a bug in Generic Frontend Server that could make it crash if a client sets characterSetNegotation bit, but didn't pass negotiation stuff in InitRequest. New YAZ client command, zversion, that sets Z39.50 version (1,2,3..). Must be issued before open, in order to be in effect. --- 2.0.9-6 2004/01/12 Debian/Windows Make the SRU server more picky WRT unknown params, etc. Bug fix: ZOOM scan response didn't return displayTerm - when present. New YAZ client command, options, that sets Z39.50 options. New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50 options from a string of tokens (one token for each option bit). Update SRW diagnostic code messages. --- 2.0.9-5 2004/01/07 Debian/Windows Handle user defined stylesheet for SRW/SRU. --- 2.0.9-4 2004/01/06 Debian/Windows Fix bug in decoding of Content-Length. --- 2.0.9-3 2004/01/06 Debian/Windows Fix a bug with decoding of XML packed records. --- 2.0.9-2 2004/01/05 Debian only Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr. Fix bug in SRW/SRU diagnostics decoding. --- 2.0.9 2004/01/05 Fixed bug in Generic Frontend Server which could drop records exceeding preferred message size. Reported and fixed by Irina Dijour. Fixed calculation of package size for structured records in Generic Frontend Server. Reported and fixed by Irina Dijour. Fixed namespace for SRW/SRU diagnostics. Fixed SEGV in yaz-client that occured for HTTP connection errors. --- 2.0.8 2003/12/22 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that this version is incompatible with version 1.0 and older YAZ SRW/SRU implementations. CQL changes to reflect recent changes to the specification: * Documentation talks about context sets instead of index sets. * Documentation talks about indexes instead of qualifiers. * The CQL-to-PQF transformer's configuration file now uses "index.set.name = " instead of the old form "qualifier.set.name = ". (Both forms are still understood but the latter is deprecated.) * CQL terms with no explicit index specified are now interpreted as cql.serverChoice instead of srw.serverChoice (which of course behaves exactly the same.) --- 2.0.7 2003/12/16 MARC conversion can now generate ISO2709 output in another character set. yaz-marcdump uses this facility if you invoke it with option -O. Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that functions from there can be used from C++. --- 2.0.6 2003/12/04 Frontend server now transfers memory from decoded packages to stream ODR for search. NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory references to show up. ZOOM-C now supports standard ZOOM option names as described in v1.4 of the ZOOM Abstract API. The older names for the same options are still also supported for the benefit of old applications. ZOOM-C supports "implementationId" and "implementationVersion" options to go along with "implementationName". These allow the user code to specify identification strings to be sent to servers. Add OID for the new ExtLite attribute set. Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes, as requested/supplid by Ere Maijala For generic frontend server, reverse the order of "toolkit-supplied / application-supplied" strings sent as implementationId, Name and Version. Also, remove the spaces around the slash. This brings the GFS in line with the behaviour of ZOOM-C on the client side. Add function ZOOM_scanset_display_term. yaz-client shows scan displayTerm if present. Utility yaz-iconv is now installed by default along with the man page yaz-iconv.1. Extend configure check for OpenSSL to use pkg-config where available (such as RedHat 9). Incorporate patch by Morten Bogeskov which allows a Unix file socket server to specify uid/gid/mask for socket using the format unix:[user=uid,][group=gid,][umask=mask,]file=path If file= is omitted the existing format is assumed, e.g. unix:path in which case the mask is 0666 (rw for everybody). Major restructure of YAZ source. All source in libyaz is in src directory. Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs), util (utility programs such as ASN.1 compiler, yaz-marcdump). Added man page for utility yaz-marcdump (used to be called marcdump). yaz-marcdump is installed by 'make install'. Fixed a memory leak in Generic Frontend Server that occurred when decoding of incoming package failed. Fixed a potential DOS attack vulnerability in COMSTACK/ODR. Change prototype of odr_perror: add const to message string. New function yaz_log_reopen which reopens log file (for log rotate, etc.) * Blocking parameter for COMSTACK cs_create is now a bit mask rather than a blocking flag. Bit 0 is set for blocking, reset for non-blocking. Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full DNS lookup. There should not be any compatibility problems with this assuming that blocking=1 or 0 is used. Fix bad reference in UNIX comstack in function cs_addrstr. Fix for compilation on AIX. The generic front-end server (server/seshigh.c) now supports returning Init diagnostics to the client in User-information-field, in accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics in an InitResponse) --- 2.0.4 2003/09/04 Allow any CQL relation (not just all,any,exact,scr). Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets that features the same UI. Implemented command update0 in YAZ client which is equivalent to update but uses old of Ext Update ASN.1. Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets in charset negotiation. Added VAL_ID_CHARSET in oid.h. Previously no OID was used for this info. ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches. It apparantely upsets EBSCO Publishing IR Z39.50 Server which returns 'malformed search term' otherwise. SortResponse member resultCount now set to NULL in sort handler of frontend server. OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if type is "opac". Add three new utility functions for translating OIDs between various formats -- symbolic name such as "Usmarc", minus-1-terminated int arrays and dotted strings such as "1.2.840.10003.9.5.1": int *oid_name_to_oid(oid_class oclass, const char *name, int *oid); char *oid_to_dotstring(const int *oid, char *oidbuf); char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf); Reverted modifications for ES Update definition for z_IU0Update (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition is back to YAZ 2.0.2. String value attributes for CCL parser. Support for OCLC's locally registered "OCLC-UserInformation" PDU, which their FirstSearch server returns in Init responses, sometimes carrying useful diagnostic information when Init fails. This has the OID 1.2.840.10003.10.1000.17.1 and is defined in the file "z39.50/oclcui.asn", where its definition is somewhat different from what OCLC document on their web-site, as required to interoperate with their servers. Support for anonymous authentication in yaz-client. Use the command "auth -". * Fix the OID of the Index Data-local "admin" Extended Service from 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of the 1000, which indicates a locally-defined OID, was a mistake. --- 2.0.3 2003/06/20 Fix CCL directive @case handling so that it affects string match for both CCL keywords and qualifiers. * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update . Decoder has been updated with ASN.1 changes as listed in http://lcweb.loc.gov/z3950/agency/defns/updateES.html Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler z_IUUpdate, remains unchanged. ZOOM_record_get may now return a record in a specific character set. For type use "form; charset=from[,to]" where form (render, xml, ..) , "from" is the character set of record as returned by target. "to" is the character set to be returned. If omitted, "to" is UTF-8. YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp New ODR utility, odr_getelement, which returns name of element for which encoding/decoding failed. Fixed ODR so that it returns error code OREQUIRED rather than ONONE in cases where a required element was omitted. Bug fix: some MARC8 sequences were not converted. New ZOOM option "step" which specifies number of records to be retrieved in one chunk. Used in conjunction with "start" and "count". SRW support for yaz-client. Use scheme http: to use it, e.g. http://host:port/db yaz-client no longer does (un)intelligent character set conversions by default. Can be enabled with charset and marc_charset commands. xmalloc trace fix for 64-bit systems such as DEC alpha. Solaris 2.6 compile fix. New function, cql_strerror() translates SRW error codes, as returned by cql_transform_error(), into human-readable English strings. Used in yaz-client diagnostics when appropriate. New CQL2RPN query-type for the command-line yaz-client, parses CQL and converts it into a type-1 query which is sent to the server. This makes CQL available for use with all Z-servers, as opposed to the tiny minority that can handle CQL queries themselves. --- 2.0.2 2003/04/28 New Debian package layout similar to the Redhat Package layout. New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record and search result respectively. --- 2.0.1 2003/04/25 Redhat package is now several packages: libyaz (runtime libraries), libyaz-devel (development and documentation, and yaz (utility programs). Package spec file by Morten Bogeskov. New member 'schema' in struct bend_fetch_rr which the name of requested schema (SRW/SRU) for record (or NULL if none was given). The fetch handler MAY set this to reflect the schema of the returned record. New member 'display_term' in struct scan_entry. GFS now sets member entries and allocates scan entries to be filled by user scan handler. In previous version, entries member was allocated by the scan handler. That still works, but the GFS will ignore member display_term - assuming it was NOT set by the handler. The fact that the GFS now allocates the entries both allows for new members and makes a scan handler easier to write. Fix CQL lex buffer overflow. SRW/SRU recordPacking. For SRW default recordPacking is string. For SRU default recordPacking is string. SRU protocol support for frontend server. Fix compile bug for systems that have nl_langinfo but CODESET undefined. Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics. Added scan for the ZOOM shell (zoomsh). --- 2.0 2003/02/23 * String Identifers for Schemas (Amendment 5). http://lcweb.loc.gov/z3950/agency/amend/am5.html Old definition for schema Odr_oid *schema; /* OPT */ New: int which; union { Odr_oid *oid; Z_InternationalString *uri; #define Z_Schema_oid 1 #define Z_Schema_uri 2 } schema; /* OPT */ * resultCount parameter to Sort Response (Amendment 1). http://lcweb.loc.gov/z3950/agency/amend/am1.html Support for SRW 1.0 over HTTP. This is an optional feature and requires libxml2 to operate. Enable SOAP by specifying --with-xml2 for configure. Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER on the same port. SRW SearchRetrieveRequests are mapped to bend_init,bend_search,bend_fetch,bend_close. Z39.50 Query Type-104 added - to facilitate CQL within Z39.50. CQL support. Source is directory 'cql'. CQL is supported in ZOOM (both SRW and Z39.50) and the YAZ client (Z39.50 only). ZOOM connections are SRW based if schem http is used for hostname in connect, e.g. z = ZOOM_connection_new("http://myserver"); ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x"); CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false, distance=n, order=true/false, relation=le, prox unit=word. If n is omitted, distance 1 is used. Fixed problem with C compiler include path in wrong order. For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value on Solaris. Patch from Ko van der Sloot. New MARC decode API. All new functions operate on a yaz_marc_t handle. The most important new functions are: yaz_marc_create, yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler, decode and destroy respectively. Decoder can produce formats MARC line, simple XML, OAI MARC and MARC XML (LoC). See include/yaz/marcdisp.h. YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts to UTF-8, UCS-32, wchar_t or Latin-1. * Prototypes for yaz_iconv_-functions moved to separate header include/yaz/yaz-iconv.h. Make a few private functions 'static' in unix.c. This prevents duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977. For ZOOM connection, the options targetImplementation{Id,Name,Version} are set when Init Response is received. New function ZOOM_connection_error_x similar to ZOOM_connection_error but returns diagnostic set as well. New function yaz_strerror which is a portable wrapper for strerror/strerror_r/GetLastMessage. * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC) is returned for MARC. If type is "oai", then OAI MARC is returned. Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch from Kang-Jin Lee. --- 1.9.2 2002/11/26 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records. Fix bad race conditions on SIGTERM and terminate gracefully in frontend server. Move retrieval (data1) module to Zebra since nobody seems to be using it. Add GRS-1 render for ZOOM using same format as yaz-client. --- 1.9.1 2002/10/05 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1). Fix broken ESpec handling in data1 module. SGML reader parses comments and makes them part of the data1 tree. Added several type casts so that YAZ compiles as C++ code. ZOOM didn't handle PDU encoding failures properly. Added more Bib-1 diagnostics (approved extensions). GNU configure: better check for iconv. More portable use of accept, getpeername. Check for socklen_t. Use int/size_t if socklen_t is not defined. --- 1.9 2002/09/06 PQF parser rejects bad queries - including those with extra characters in them. PQF parser used to silently ignore that. Cleaner API for PQF added, which allows you to get detailed error information for bad queries (see yaz/pquery.h). Fixed bug in ZOOM_record_get for type "database". Implemented mini iconv library supporting conversions between UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c. * Removed XML reader (d1_expat.c). It's part of Zebra instead. --- 1.8.9 2002/08/20 Fixed ZOOM C record cache so that preferredRecordSyntax and elementSetName is used to check for already fetched records. --- 1.8.8 2002/08/02 Added three members in bend_initrequest structure to facilitate character set negotiation. Fixed a bug in frontend server that could cause indefinite loops under rare conditions. Revised character set utilities (charneg.h) so that encoding UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately. For PQF, directive @term sets term type for Scan/Search. Here is general, string, numeric, null. The term type is inherited - just like @attr. New call odr_set_charset that sets character set conversion for international-strings on a ODR stream. Prototype is: int odr_set_charset(ODR o, const char *to, const char *from); The InternationalString is still represented as C string in YAZ so native strings of type UTF-8, ASCII, etc. will work (UTF-16 won't). On the protocol level, you can use any encoding. Support for UNIX sockets in ZOOM. Solaris recv sometimes returns errno == ENOENT. It is treated as EINPROGRESS. COMSTACK patch by Ko van der Sloot. New COMSTACK of type UNIX Socket. Use "unix:/path" as address for both client and server. Code by Morten Bogeskov. --- 1.8.7 2002/05/22 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so that they can be used directly from Visual Basic. You must recompile your windows APP if you're using ZOOM. Character Set and Language Negotiation(3) for ZOOM API and YAZ client. Commands "lang" and "charset" sets language and character set respectively. Options "lang" and "charset" is interpreted by the ZOOM API. Note, these are not part of the official ZOOM spec) All is due to Oleg Kolobov. Attributes from multiple CCL fields may be OR'ed rather than merged using directive "@field or". Fields are still merged by default - equivalent to "@field merge". Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch by Oleg Kolobov. Fixed bug in zget for parameter ExtendedServicesResponse. Fix OID for ILL. --- 1.8.6 2002/03/25 Added PQF feature: '@attr type=value' may be written as '@type=value'. Client displays USR.1:SearchResult-1 (hits per term). Additional Search Info for search in Generic Frontend Server. Fixed CCL parsing of "field=s". WIN32 installer - using the excellent NSIS software from nullsoft. Fixed CCL parsing of "field = - ". Added function yaz_marc_decode that decodes MARC for line mode display or XML (similar to that used by JZKit). Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the Z39.50. But ISO/ILL was, however. Added patch by Rustam T. Usmanov that implements Z39.50 duplicate detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3). See: http://lcweb.loc.gov/z3950/agency/amend/am2.html http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html --- 1.8.5 2002/02/03 New YAZ client features: Command completion and new commands: push_command, set_apdufile, set_marcdump, set_cclfields, register_oid. Code provided by Jacob Poulsen. New call oid_trav, that visits all registered OIDs via callback. Function ZOOM_record_get now returns const char pointer rather than void pointer. It saves a lot of type casts. For YAZ client, command "auth" now allows you to set authentication in IdPass style. It is enabled when three tokens are given - order is user, group and password. Fix memory leaks in MARC record handling for ZOOM. New option for YAZ client, -k that sets maximum record size. Similar to -k option for generic frontend server and yaz-ztest. More fixes for scan. Non-zero stepSize handled. OID's fixes. Prefix query parser reports "fail" when bad attribute set is given. Fix in MARC decoder. Proximity logging. Fix for attribute set in scan handler for server. Patches by Shigeru Ishida. SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM works with SSL. Configure option --with-openssl= now works when a directory is specified. Patch provided by Morten Bogeskov. New option for YAZ client, -u , that sets authentication. ZOOM fix: error information was sometimes "missing", since error was cleared/reset too when it shouldn't. ZOOM_record_get returns ISO2709 buffer when "raw" is given. --- 1.8.4 2002/01/04 Scan for ZOOM API. New object ZOOM_scanset. New functions ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and ZOOM_scanset_destroy. New ZOOM function, ZOOM_connection_last_event, that returns type of last event (such as "receive data", "send data", "apdu received", etc. New ZOOM option, schema, that specifies schema for retrieval. New CCL feature. Qualifiers can be aliases for one or more other qualifiers (if more than one is given, OR is used). ZOOM uses named result sets if target supports it. Two new YAZ client commands: . (dot, which sources a script of YAZ client commands), and ! (to execute shell command.). Implemented by Jacob Poulsen. Working on Debian packages. --- 1.8.3 2001/11/19 YAZ client enables named result sets only if target supports it. *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_. * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get with key="host" to get same result. * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get. Function Z3950_resultset_record(s) returns references to records "owned" by resultset. To become owner use Z3950_record_clone. Function z_ext_record handles Extended Services. Thanks to Irina Dijour. --- 1.8.2 2001/11/12 CCL Parser fix: ignore token comma when dealing with and-lists. Documentation updates for COMSTACK. * ZOOM changes. Query object renamed from Z3950_search to Z3950_query. Changed prototype Z3950_records. For some functions, int parameters were changed to size_t. TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak on some Unices. New MARC decode/display function, marc_display_exl, which properly rejects non-ISO2709 records. YAZ client uses it. --- 1.8.1 2001/10/29 Fix bug: local attribute set wasn't set correctly in PQF strings. --- 1.8 2001/10/25 * Old Z39.50 codecs no longer supported. Added ZOOM C binding. See http://zoom.z3950.org/ Renamed states for COMSTACKs to avoid confusion with events. Implemented cs_look and proper cs_rcvconnect. Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas. Configure detects POSIX threads on OpenBSD. When sort flag 'i' was specified in yaz-client the caseSensitivy flag was set to a wrong value. Thanks to Robert Sanderson for reporting this. When error is returned from present handler, non-surrogate diagnostic is returned in present response (and fetch handler is no longer called). * Minor adjustments to pquery parser (PQF). Token characters may be escaped by using backslash (C-style). PQF parser allows string attribute values to be specified. For @attr, non-numeric characters after the equal-sign are treated as strings (e.g. @attr 9=title). CCL trunction character may be defined (@truncation in file) * function zget_ExtendedServicesRequest sets waitAction to waitIfPossible (was wait). Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks to Matthew Carey. CCL operator names may be set in field definition files (CCL_bibset). See ccl/bib1 for an example. Fixes in ASN.1 compiler for C++ compatibility. * Renamed members "and" and "or" in struct Z_Operator to "op_and" and "op_or" to avoid conflict with C++. Fixed problem with GNU readline detection on Redhat 7.0. Added step-size for Scan backend handler. Fixed bug that made the frontend server crash when no attribute set was specified for scan. Front-end server automatically switches to original working directory when installed as an NT service. Previously -w had to be specified to make it work. Added extended attributes for retrieval module (data1), so that data1 records carry d1_readXML/SGML attributes. d1_read also supports null-data rules ( ) On UNIX when POSIX threads are available, a separate library libyazthread is created. Programmers should link with that library and the yaz library when using threads. The reason for the split was that some applications on Linux, such as Apache, doesn't work well when using shared objects that relies on threads. Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest (or any frontend server) in SSL mode by specifying ssl: followed by address. Only tested on UNIX. Added feature for CCL module. Virtual structure s=al or s=ol generates and-list and or-list respectively instead of phrase search. Added some OID's. * Added prefix "yaz_" for the functions log_init.., log_file.. and log_mask_str. This was done to avoid name conflicts with other libraries (such as other PHP extensions). Added raw OID member for preferred record syntax (request_format_raw) and returned record syntax (output_format_raw) for backend fetch method. Config file yaz-config now accepts options so that it returns specific compile settings, etc. Thanks to Morten Bogeskov Shared library support for UNIX using GNU libtool. * Modified backend interface. Request/Response struct's replaced by one read/write C struct. For example bend_fetchrequest and bend_fetchresult have been replaced by single bend_fetch_rr struct. Every handler - even search has to be registered in bend_init handler. This means that the YAZ library no longer refers to external functions and it makes it possible to make the whole thing a single DLL/SO. Added Segment handler for backend server. Added Zmbol/Zebra administrative functions to YAZ client. Threaded frontend server on UNIX (when POSIX Threads are available). Starting the server with option -T enables multi-threading. --- 1.6 2000/03/03 Added configure option --enable-comp/disable-comp to control use of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders located in sub directory asn. YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed in ${exec_prefix}/bin along with the other programs yaz-client and yaz-ztest. GNU automake used to maintain makefiles. Added several OID's. Changed retrieval module so that we can load records with no abstract syntax defined. Tagpaths in these records are fully composed of string tags. Implemented ISO ILL protocol. Refer to stuff in sub directory ill. --- 1.5 1999/12/10 On UNIX, the generated makefile now supports a proper 'make install'. The prefix can be set via GNU configure to set the install location (default is /usr/local). * YAZ programs client and ztest were renamed to yaz-client and yaz-ztest to avoid conflicts when users install YAZ in "standard" locations, such as /usr/bin,/usr/local/bin,etc. * YAZ Header files were moved from include to include/yaz. YAZ Header files are referred to as include rather than . The YAZ include path (-I ..) is therefore the same as before. Programmers should update their #include statements or use -Ipath/include/yaz instead. The main motivation for doing this change is that YAZ header files can be installed in "standard" locations /usr/include,/usr/local/include without introducing conflicts, since ALL YAZ header files are stored in subdirectory yaz (under /usr/include for example). Compilation of YAZ for WIN32 is now handled by an nmake-style makefile rather than project/workspace files. We switched because project files are incompatible between Visual C++ 5 and 6. Refer to windows.txt for details. Changed name of logging function, logf, to yaz_log, to prevent name clash with some math-log functions. The YAZ header log.h defines logf to yaz_log (#define) so there should be no incompatibilities by this modification. Added bend_start/bend_stop handlers for server. These handler are called on start/stop of server. For windows they are called whenever a service is started/stopped. * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using a fairly small ASN.1 compiler written in Tcl. The compiler is located in util/yc.tcl. The auto-generated C code structures are, in a few cases, incompatible with the old decoders. There are differences in the following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse, Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat. The preprocessor variable ASN_COMPILED is defined when the compiled ASN.1 is being used. Encoder/decoder routines as well as the Z39.50 protocol ASN.1 is located sub directory z39.50. If you wish to use the old encoders/decoders you can specify --disable-yc for configure. Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled version so that it supports both new - and old version of DB Update * Added 'name' parameter to ODR encoder/decoder routines to facilitate pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the change. The name parameter can be set to 0 in which no name is specified for the construction. The macros odr_implicit and odr_explicit sets name parameter to zero for the construction involved. New macros odr_implicit_tag and odr_explicit_tag are similar to the others, except that a name parameter is added. For programmers' that don't use ODR they probably only need to change the call to z_APDU and z_External. Added access control facility by interfacing the TCP wrapper library. YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and tcpd.h on Unix systems. For the server, option -d specifies the name of the daemon and enables the access control as specified in hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5). Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van den Dool . Added reference ID parameter to most functions in server API - refer to backend.h. Thanks to Hans van den Dool . Changed name of ccl library to libccl.a (was ccl.a). Fixed bug in decoder for Explain (Category TargetInfo). Added support for GNU readline in client. Thanks to Jacob Poulsen . GNU configure attempts to detect if readline is available. * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE IMPLEMENTATION! This change was made to the development version before the ZIG decided to retract the amendment. If any users MUST be compatible with the original Update definition, PLEASE CONTACT US, and we will include a separate definition corresponding to the old Update ES. Note that because of the change to the ASN.1 of the TaskPackageRecordStructure we cannot define a single structure that will support both versions. * Added const modifier to buffer parameter for some ODR/BER encoding routines: ber_dectag, ber_declen, odp_more_chunks, completeBER, completeWAIS, odr_dumpBER. Fixed bug in client.c which caused a crash when a scanResponse didn't contain positionOfTerm. * Fixed inconsistency in the ScanResponse/ListEntries protocol. This * will cause an error in a client if a non-YAZ target sends both a * list of Scan entries and non-surrogate diagnostics. Retrieval module enhancements. Tag sets may be typed in the reference to it. From the .abs-file the "tagset" directive takes a third optional integer type for the tag set referenced. From a .tag-file the "include" directive takes a third optional type as well. The old "type" directive in the tag set itself is still recognized but acts as the default type for the tag set. Backend interface change. Individual Scan terms returned from bend_scan may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry in include/backend.h. Retrieval module enhancements. Multiple tag sets and attribute sets may be specified in abstract syntax specs. Revised the error/warning for logging messages reported by the retrieval module when reading the various spec files. Object Identifier system (oid_..) changed. The API is backwards compatible but the oid-routines now allocates new OID's when needed. Raw OID's may be specified in oid_getvalbyname. YAZ now uses GNU configure to generate Makefile(s). * Minor changes in some of the member names of DeleteResultSetRequest and DeleteResultSetResponse. See include/proto.h. * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h) and added member 'languages' in TargetInfo (which was missing). Changed the way attribute sets are handled in the retrieval module. These are now cached, just like the abstract syntaxes (schemas). Changed YAZ so that it links with compiled ASN.1. Added Explain-schema definitions and mapping routines. The following Explain categories have been implemented: AttributeDetails, AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo. Fixed minor bug in Windows version of Server Library. --- 1.4pl2+ 1998/4/17 (Released with Zebra) Added Extended Services to server (backend.h). Thanks to Charles Woodfield. Added EXTERNAL: UNIverse Resource Report (non-standard). Implemened odr_enum and odr_set_of functions to handle ASN.1 types ENUMERATED and SET OF. * Added 'const' to some of the char pointer arguments for the functions, data1_read_node, data1_getelementbytagname, data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname, data1_get_absyn. Fixed bug in data1_insert_taggeddata - the last_child member of parent wasn't initialised. * Changed data1_read_record and data1_read_node so that the supplied "SGML"-buffer is read-only. In particular the resulting data1 - tree doesn't refer to any parts of the "SGML"-buffer. Fixed bug in server library (Windows version of statserv_remove). * Changed code so that it compiles as C++. The type definition of Odr_fun which is a member of Odr_arm was changed. The result is, that an explicit typecast is needed for the fun pointer when using Odr_arm - as in: {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass}, Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag). Implemented the new structured date and time definition as approved by the ZIG. Added schemaId element to the specificTag in Espec-1 (also approved at the last ZIG). Thanks to RVDM. Added some Object identifiers (RVDM). Changed the Update Extended Service (RVDM). Added command "refid" to client which specifies referenceId for the following requests. Implemented extended service handling for server. See ztest.c for an example as well as backend.h. New handlers are registerd in the Init handler. * Changed interface for sort in server. Added new members to statserv_options_block. It allows a server to read options from another source than just the command line. Thanks to Charles Woodfield. * Changed definition of Z_Triple in file prt-grs.h - member boolean renamed to zboolean. Some C++ compilers complained about the name. Minor changes to gils.abs. Added index 's' (sort) on title and date/time-last-modified. --- 1.4pl2 1998/1/30 Fixed bug in server library regarding inetd mode (-i). This bug was introduced by release 1.4. --- 1.4pl1 1998/1/29 Added sort facility in client and backend server interface. Fixed problem with dependencies in Makefile(s). Fixed bugs for encoders/decoders of extended services and SearchInfoReport. Implemented sub-tree feature for schemas. Sub-trees are referenced in *.abs-files. See explain.abs for an example of the use of this feature. Modified bib1.att; local attributes for ANY didn't include ANY itself (only affects use of the retrieval module). Fixed bug in plain SGML reader in function data1_read_node: tags with prefix "var" was incorrectly interpreted as variants. Added feature "sub-schemas" to enable references to - and definitions of - group of elements. * Removed member parent from type data1_element (in data1.h). Implemented function odr_nullval() that returns the value of ODR_NULLVAL. * Removed member num_children from data1_node (in data1.h). Made NT service interface part of the server library. The function statserv_main uses the NT service when required and calls the statserv_start / statserv_close routines. Routine zget_SearchRequest and zget_PresentRequest fills resultSetName/Id member with "default" instead of "Default". Fixed memory leak in server. Request queue member wasn't freed. Fixed nmem_exit so that memory is freed. --- 1.4 1997/10/2 Revised the CCL parser utility to be thread safe. Added function, oid_ent_to_oid, to replace the function oid_getoidbyent, which is not thread safe. * Added nmem_init and nmem_exit to initialize and release NMEM resources. Function nmem_init should be called once in the initial thread before NMEM/ODR is used. statserv.c and client.c have been changed accordingly. The change was necessary to make NMEM thread safe. The NMEM memory pool is shared amongst threads in a process. Unix-based applications will still work fine without calling this. Added NT Services interface for the the Z39.50 (statserv) Server. Refer to the ztest.c source on the usage. Windows 95/NT port using MSVC5.0. Project files are included in the distribution. * Defined new 'global' handle for the retrieval (data1) system. The new handled, data1_handle, describes the state of the data1 system. This handle is passed as first argument to virtually all data1 related routines. The functions data1_create and data1_destroy creates and destroys a data1 handle respectively. Added ODR encode stream member to all backend request structures init, search, scan etc. This stream should be used to allocate all memory used for the response when thread safe operation is needed. Changed the comstack utility, cs_addstr, to be thread safe. The returned hostname string returned by the function is now part the COMSTACK instance. Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr function. The cs_straddr takes a COMSTACK handle as argument, so this function must be used after cs_create and before bind/connect. This function is thread safe. Moved test server to 'ztest' directory - generic server code still in 'server' directory. Made prefix query (pquery.c) utility thread safe. Added new function modifier YAZ_EXPORT to 'export' public DLL functions when using windows (see include/yconfig.h). Added definitions to the OID database (util/oid.c) (RVDM). Added new BIB-1 diagnostic messages to the handler diagbib1_str. Added call to ccl_rpn_delete in client program. Added ODR argument to ccl_rpn_query and ccl_scan_query to provide release of RPN structure. Added support for C++, headers uses extern "C" for public definitions. With input from RVDM. In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent. Thanks to Ronald van der Meer (RVDM). Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM. Added support for private extensions to the OID database (oid_setprivateoids()). Thanks to RVDM. Added optional, physical ANY (key replication) Fixed null-reference problem in GRS-1 output filter. Proximity operator added to Prefix Query Format (PQF). In test client command "base" accepts multiple databases. Fixed bug in cs_close stack that caused trouble with WINSOCK. --- 1.3 1996/10/11 Fixed tagging bug in ResourceReportResponse PDU encoder/decode. Smallish bug-fixes in the new encoders/decoders (explain). Bug fixed in DeleteRequest. Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder. Fixed tagging bug in ResourceReportResponse PDU encoder/decode. Added SOIF syntax (using private OID for now) to retrieval module and client. Added Update extended service. Added SearchResult-1 additional info structure. Added optional CCL (ISO8777) interpreter as separate module. Available in linemode client. --- 1.2 1996/6/10 (1st anniversary release) Added Summary record syntax. Lightly tested. Added OPAC record syntax. Untested. Added ResourceReport service encoders/decoders. Untested. Fixed bug in z_Unit - wrong tagging on unitSystem. Fixed bug in the DiagRecs decoder. Added options for max PDU size and session timeout to frontend-server. Added documentation of query-language parsers and other supporting utilities. [frontend-server] Added Attribute set to the bend_scanrequest API. [frontend-server] NextResultSetPosition was sometimes set incorrectly when surrogate diagnostics were generated. [retrieval] Allow multiple local values for attribute. [retrieval] Allow multiple attributes per element in .abs files. index type. [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter. --- 1.1pl2 1996/4/10 Minor changes, mostly specific to Zebra's requirements (retrieval) --- 1.1 1996/2/20 Repaired bug in frontend server when running multiple listening endpoints in dynamic mode. z_External() now won't break if a known, ASN.1 value comes encapsulated in an octet-string. The value will pass through unmodified in an Odr_oct. Added a bit of code to the demo client to decode & display ASN.1-structured records represented in the octet-aligned branch of the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this. Added z_ext_getentbyref() to the ASN module. Doc updated. * Completed the SCAN definition in the ASN module. This may break SCAN code based on older YAZ-versions at compile-time. The fix is easy - look in proto.h. * Added 'displayTerm' and OtherInformation to the TermInfo structure under the SCAN definition. Remember to initialize this, server-people. Comstack should now support the WAIS protocol in TCP/IP mode. Note that this does not extend to ODR and ASN. Comstack allows insertion of established socket (primarily for inetd-operation of servers). Doc updated. Front-end server can now start from the inetd in TCP mode. Doc updated. --- 1.0pl4 1996/1/24 Added Sort PDU. Fixed small problem in SUTRS-filter. A newline was sometimes inserted before the rank and record number. Adjustments to the frontend server. Fixed diagnostic BER dumper. It ignored the file argument. --- 1.0pl3 1996/1/2 Various changes to retrieval module. Changed the union discriminators of the protocol files from enums to ints paired with #defines. *Changed oident.class to oident.oclass to avoid a reserved word in C++ compilers. *Changed operator in the RPN structure to 'roperator', again to avoid a conflict with C++. Fixed problems in Explain decoders/encoders. --- 1.0pl2 1995/12/6 Memory bug in log module fixed. --- 1.0pl1 1995/12/5 Occasional malloc() of 0 bytes fixed in d1_espec.c. Bug in Explain DatabaseInfo module fixed. Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows. --- 1.0 1995/11/28 The shift to v1.0 signals that we now consider the *core* functionality of YAZ reasonably stable (the core being more or less equivalent to Z39.50-1992). Some of the really nifty v3 stuff is still not heavily tested (Explain not at all - though that will happen soonish). Minor changes to code to support Windows port. Various minor changes after we're getting to use GRS-1 & co. more. Added Espec-1 format. Added VisibleString field body type to GRS-1. It is illegal acc. to my copy of the protocol and it cannot be selected when encoding (maps into 'string' when decoding). Needed to talk to some servers. Demo client can request simple element set names. Added Diagnostic Format encoders/decoders. Added simple Close handling to frontend server (no hooks for resource reporting yet), and demonstration client. Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address. --- 1.0b3 1995/08/24 Fixed bug in the frontend-server. The numberOfRecordsReturned field was handled incorrectly when records were requested in the searchResponse. This will only affect you if you use the frontend-server. Added GRS-1 encoders/decoders to the service-level API. Lightly tested. Test-client will ask for and print GRS1. Ztest will return dummy records on request. Added Explain encoders/decoders to the service-level API. Untested. Added Extended Services: Item Order encoders and decoders to the Service- level API. Untested. We could use a recent copy of the pertinent bits of the ILL protocol to add those bits. Added diagnostic format 1 encoders/decoders to the service-level API. Untested. Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to odr_cons.c, which causes a more correct output. Fixed handling of searchRequest in frontend server. NextResultSetPosition was always set to 0 when no records were requested in the searchRequest. * Added better external-handling. This shouldn't harm old code that *encodes* externals. It can break code that looks for a 'single-ASN1-type' representation, since those types that are known are now decoded immediately. Look at the SUTRS sample code in seshigh.c and client.c. Documentation updated. Handling of structured records in bend_fetchresponse. Length -1 marks structured record, type is deduced from format field. --- 1.0b2 1995/06/27 Fairly quick maintenance release to add SUTRS support. Fixed handling of SUTRS records in the demonstration client. * Added format field to the bend_fetchrequest and bend_fetchresponce structures of the backend API (frontend server). When the record is returned, the value of the format field is mapped to an OID. The value VAL_SUTRS will also cause a slightly different ASN.1 packaging of the record. The special value VAL_NONE in the bend_request means that no specific format was requested by the client. Documentation updated accordingly. Test server (ztest) will return a fixed dummy SUTRS record if your client requests SUTRS. Documentation updated accordingly. You can now set external libraries and RANLIB support in the top-level Makefile. --- 1.0b 1995/06/19 First public release.
