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().
