Changes in release 0.22.0: * Remove the const qualifier from the reason_phrase field in ne_status. - ne_parse_statusline() now strdup's the reason_phrase * Remove the status_line argument from ne_207_end_propstat and _end_response * Change ne_session_create, ne_session_proxy, ne_sock_connect, and the 'port' field of the ne_uri structure to use an unsigned int for port numbers * ne_uri_defaultport returns unsigned and '0' on an unknown port (not -1). * Changes to hooks interface: - pass an ne_request pointer to per-request hooks - replace "accessor" hooks with ne_{get,set}_{request,session}_private * Authentication changes: - the hooks changes fix a segfault if auth is enabled for an SSL session through a proxy server - fix ne_forget_auth segfault if either proxy or server auth are not used * Improvements to persistent connection retry logic and error handling in request code; fixing some cases where some errors where incorrectly treated as a persistent connection timeout - a TCP RST at the appropriate time is now treated as a persistent connection timeout. - handle persistent connection timeouts on SSL connections * Changes to SSL support: - improved error handling - OpenSSL 0.9.6f or later is required for security fixes and functional correctness; 0.9.6 or later required for functional correctness - use --with-force-ssl to override OpenSSL version check - fix for proxy CONNECT tunnelling with some proxies (e.g. Traffic-Server) - fix potential segfault if client cert. provider callback is used - fix to use supplied password callback for PEM-encoded client certificates (Daniel Berlin <dberlin@dberlin.org>) * strerror_r is used if available for thread-safe error handling. * Remove ne_read_file(). * ne_version_match replaces ne_version_minimum (semantics changed slightly). * XML request bodies use a content-type of "application/xml" now; applications can use NE_XML_MEDIA_TYPE from ne_xml.h * Fix decompress code on big-endian or 64-bit platforms. * Fix to build on Darwin 6 (aka Mac OS X 10.2) (Wilfredo Sánchez, <wsanchez@mit.edu>) * Win32 changes: - remove conflict between OpenSSL's X509_NAME and recent versions of the Platform SDK (Branko Čibej) - fix inverted debug/non-debug build logic (Branko Čibej) - add NODAV and OPENSSL_STATIC flags to neon.mak (Gerald Richter) Changes in release 0.21.3: * Fix segfault if using proxy server with SSL session and server certificate verification fails. * Fix leak of proxy hostname once per session (if a proxy is used). * Add --with-libs configure argument; e.g. --with-libs=/usr/local picks up any support libraries in /usr/local/{lib,include} Changes in release 0.21.2: * Fix 'make install' for VPATH builds. * Use $(mandir) for installing man pages (Rodney Dawes). * Follow some simple (yet illegal) relativeURI redirects. * Always build ne_compress.obj in Win32 build (Branko Čibej). * Fix decompression logic bug (Justin Erenkrantz <jerenkrantz@apache.org>) (could give a decompress failure for particular responses) * Fix ne_proppatch() to submit lock tokens for available locks. * More optimisation of ne_sock_readline. Changes in release 0.21.1: * Don't include default SSL port in Host request header, which can help interoperability with misbehaving servers (thanks to Rodney Dawes <dobey@ximian.com>). * Don't give a "truncated response" error from ne_decompress_destroy if the acceptance function returns non-zero. * Fix for Win32 build (Sander Striker <striker@apache.org>). * Fix for cookie name/value being free()d (thanks to Dan Mullen). * Optimisation of ne_sock_readline. Changes in release 0.21.0: * Socket layer implements read buffering; efficiency and performance improvement.

To use SOCKS or SSL libraries/headers in non-system locations, use ./configure CPPFLAGS=-I/... LDFLAGS=-L/... * Reference documentation included for most of ne_alloc.h and ne_string.h, and parts of ne_session.h and ne_request.h. - see installed man pages, HTML documentation. Changes in release 0.20.0: * Major changes to DAV lock handling interface (ne_locks.h): - struct ne_lock uses a full URI structure to identify locked resource - ne_lock() requires that owner/token fields are malloc-allocated (or NULL) on entry - introduce a "lock store" type, ne_lock_store, to replace the lock session; accessor functions all renamed to ne_lockstore_*. - ne_lock_iterate replaced with a first/next "cursor"-style interface - If: headers use an absoluteURI (RFC2518 compliance fix). - fix for handling shared locks on DAV servers which return many active locks in the LOCK response (thanks to Keith Wannamaker) * Moved URI/path manipulation functions under ne_* namespace (ne_uri.h): - path handling functions renamed to ne_path_* - URI structure handling to ne_uri_*; struct uri becomes ne_uri. - ne_uri_parse doesn't take a 'defaults' parameter any more - if URI port is unspecified, ne_uri_parse sets port to 0 not -1. - added ne_uri_unparse and ne_uri_defaultport functions. * New 'ne_fill_server_uri' function to initialize a URI structure with the server details for a given session (useful with locks interface). * ne_decompress_{reader,destroy} are defined as passthrough-functions if zlib support is not enabled. * API change: ne_ssl_provide_fn returns void not int. * Added NE_SSL_FAILMASK for verify failure sanity check. * Removed return codes NE_SERVERAUTH and and NE_AUTHPROXY; correct documentation, NE_PROXYAUTH is given for proxy auth failure. * Require zlib >= 1.1.4 to avoid possible vulnerability in earlier versions. See http://www.gzip.org/zlib/advisory-2002-03-11.txt for more details. (version check can be skipped by passing --with-force-zlib to configure) * New 'ne_ssl_readable_dname' function to create a human-readable string from an X509 distinguished name. * Fix support for newer versions of libxml2 (thanks to Jon Trowbridge <trow@gnu.org>). * Fix corruption of reason_phrase in status object returned by ne_propset_status. * More lenient handling of whitespace in response headers. * ne_content_type_handler will give a charset of "ISO-8859-1" if no charset parameter is specified for a text/* media type (as per RFC2616). * Miscellaneous cleanups and fixes (Jeff Johnson <jbj@redhat.com>).

Changes in release 0.19.0: * Major API change: ne_session_create now takes (scheme, hostname, port) arguments: a session is clarified to be "a group of requests to a certain server". - removal of ne_session_server, ne_set_secure, and ne_set_proxy_decider - ne_session_proxy returns void. - DNS lookups are delayed until request dispatch time. * Significant improvements to TLS/SSL support: - SSL is enabled if scheme passed to ne_session_create is "https" - new interfaces to load CA certs and to load SSL library's bundled CA certs - add server cert verification callback. An SSL connection to a server with an unknown CA will now fail unless a verification callback is used. - enable SSL session caching (performance improvement) - support for wildcard server certs where commonName is "*.example.com". - thanks to Tommi Komulainen for the contribution of code from mutt's IMAP/SSL implementation under the LGPL, from which bits of this were derived. * Improved SSL client certificate support: - far simpler interface, all done at ne_session.h level. - supports PKCS#12 and PEM-encoded certificates. - optional callback for only providing client when demanded by server. * Support for TLS upgrade is removed, since it isn't useful. * If NEON_SSL is defined, API extensions are available to: - allow access to the SSL_CTX * to adjust session SSL options - retrieve the server certificate (X509 *) * Decompress fixes: - fix potential segfault in ne_decompress_destroy - check the CRC of the deflated output (and fail if it doesn't match) - fail appropriately on truncated responses, and trailing bytes in response. * Added ne_set_read_timeout to use configurable timeout on socket reads. * Malformed response headers will be ignored rather than failing the request. * ne_set_error takes printf-style vararg. * Fixes for ne_get_range and improve error handling. * Functions which append to an ne_buffer do not return a success value, but they do use ne_realloc/ne_malloc under the hood now, so an OOM callback will be used (with the usual caveats). * XML interface does not strip leading whitespace from cdata by default, the NE_XML_STRIPWS flag is available to restore this feature if required. * Upgraded to libtool 1.4.2: - should fix --enable-shared on Mac OS X 10.1 * Test suite now contains over one hundred tests. Changes in release 0.18.5: * Removed old neon.dsp, neon.dsw. * Update Win32 build to add OpenSSL and zlib support (Branko Čibej). * Fix ne_compress.c to compile on Win32 (Branko Čibej). Changes in release 0.18.4: * Fixes for Content-Type parsing using ne_content_type_handler (Greg Stein) - also now parses the charset parameter from header value. * Removed ne_concat() function, which didn't work and wasn't used. Changes in release 0.18.3: * Fix parsing lock timeout from server (Arun Garg). * Send Timeout headers in LOCK and refresh LOCK requests (Arun Garg). * Updated neon.mak and config.hw.in for Win32 build (patch from Branko Čibej <brane@xbc.nu>). * Define XML_BYTE_ORDER for bundled expat build in support macro NEON_XML_PARSER(). Changes in release 0.18.2: * Fix --with-neon=PATH in support macros. * Support DESTDIR in Makefile install targets (patch by Pawel Golaszewski <blues@blysk.ds.pg.gda.pl>). * Portability fixes: - fix configure check for time_t on some platforms (e.g Solaris 2.6). - remove expect100_works bitfield in ne_session structure (thanks to Yan Periard <yperiard@ems.net>). Changes in release 0.18.1: * Minor fix for authentication: "attempt" counter was not reset correctly after authentication failed, so subsequent requests would not authenticate correctly either. * API change: ne_session_destroy returns void (there was no error case). * Portability fixes (non-GCC compilers, 64-bit platforms, UnixWare 7) * Optimisations in string manipulation routines. * config.hw is included in the release tarball again. * Improvements in the autoconf support macros: - check for neon-config in PATH if --with-neon is not given - stop if --with-neon is used, and the check for external neon fails - added NEON_WITHOUT_ACL to prevent build of ne_acl.o Changes in release 0.18.0: * API change: authentication callback is passed fixed-size username/password buffers, and an 'attempt' counter. Authentication is retried *forever* until either it succeeds, or the callback returns non-zero. * API clarifications: - ne_propname may have a NULL nspace field, indicating the property has no namespace. This holds for properties returned by the propfind interfaces. - added NE_ELM_PROPS_UNUSED as the lowest element number which should be used with handlers added to the XML parser returned by ne_propfind_get_parser. * Fixes and cleanups of lock discovery interface. * Fix for short write handling in ne_get() (thanks to rado <dzusto@yahoo.com>). * Fix for XML namespace prefix handling where a prefix could be mapped to an incorrect URI (e.g. in PROPFINDs against mod_dav with >10 namespaces used) * Add '--support <feature>' option to neon-config; the script exits with success if given feature is supported. Known features are ssl, dav, zlib. * Support for SSL, DAV, zlib is exported by neon.m4 as shell variable NEON_SUPPORTS_{SSL,DAV,ZLIB}={yes,no} for bundled and external builds. * `neon-config --cflags` won't include -I/usr/include for SSL build. * Fix to call progress callbacks while sending request bodies again. * Test changes: - portability fixes, auth interface and progress tests. Changes in release 0.17.2: * Accept Status-Lines with no reason phrase (Jeremy Elson). * Fix handling of persistent connection timeout, and better error handling if sending a request fails. * Fix crashes in locking code. * Return parse error on XML namespace prefix declaration with an empty value. Thanks to Julian Reschke. * Allow passing property names with NULL namespace to ne_proppatch. * Fix for cross-compilation (Mo DeJong). * Moved ne_propname definition from ne_207.h to ne_props.h. * Test changes: - updated for Status-Line parsing changes (Jeremy Elson) - better persistent connection tests - fixed for --disable-webdav build Changes in release 0.17.1: * Add support for ACL method (Arun Garg <arung@pspl.co.in>), see ne_acl.h. * Fixes and clean up of libraries exported via `neon-config --libs' * Fix timezone handling when parsing dates (on some platforms). * Upgrade to autoconf 2.52 and libtool 1.4 (thanks to Mo DeJong). * Cleanup/simplification of request dispatching: - better handling of error cases, including fix for a possible infinite loop when the server closes the connection prematurely. * Add '--without-zlib' configure option. * Test changes: - prettify output; imitate Perl test suite output. - add tests for interim 1xx responses, persistent connections, more unbounded operations. Changes in release 0.17.0: * Add support for decoding gzip Content-Encoding: see ne_compress.h. - built if zlib is found; `neon-config --cflags' will define NEON_ZLIB if so. * Rewrite hooks interface to register individual callbacks. - inspired by the Apache 2.0/APR hooks interface * Register cookies hooks using ne_cookie_register(). * Clean up configure scripts to enable use of autoconf 2.5x (Mo DeJong). * Use new endianess configure macro to allow cross-compiling (Mo DeJong). * Fix invalid C code in sock_init() in Win32 build (Mo DeJong). * Fix use of signal() on Win32 (Mo DeJong). * Workaround libxml 1.x string handling not being UTF-8. * Test changes: - add tests for decompression interface. Changes in release 0.16.1: * Also handle write errors in ne_get_range. * Dump request body blocks in debugging mode. * Fix ne_shave() causing memory corruption when the result should have been the empty string. * Refactor auth header parsing code; more efficient now. - fixes digest auth RFC2617-style broken in 0.16.0 Changes in release 0.16.0: * API change: ne_copy takes a depth parameter (thanks to Arun Garg, Medha Atre) * API change: validate callback to ne_xml also takes a userdata arg. * Added 'ne_lock_refresh' for performing lock refresh (Arun Garg). * Add SSL support to Win32 build (Peter Boos <PediB@colorfullife.com>) (see INSTALL.win32 for details). Compile with USE_DAV_LOCKS also. * Remove Server header parser for 100-continue support in ne_options. (and remove broken_expect100 from ne_server_capabilities). * Set SIGPIPE disposition to "ignored" in sock_init(). * On platforms with setvbuf(), turn off buffering for the debug log stream. * Ignore repeated calls to sock_init(). * Fixes to error handling in ne_get_range. * Minor improvements to memory handling in auth code. * Fix for start_propstat callback being called with NULL response argument when given invalid XML, causing a segfault in propfind code. * Test changes: - add regression test for the propfind segfault. - handle segfaults better (reap the child, flush the debug log). Changes in release 0.15.3: * Fix --with-expat=DIR build. Changes in release 0.15.2: * Fix Win32 for XML parser changes (Gerald Richter). * Substitute versions into config.hw at distribution time. * Add date parser for ISO8601-formatted dates as defined by RFC2518, e.g. the creationdate property (Taisuke Yamada <tai@iij.ad.jp>). * Fix Y2K bug in RFC1036 date parsing algorithm. * Test changes: - add tests for date parsing functions. Changes in release 0.15.1: * Win32 update from Gerald Richter <richter@ecos.de> - new files neon.mak, INSTALL.win32 * Fix for ne_socket.h includes (Mo DeJong). * More improvements for XML parser selection logic: - if parser is required, be sure to fail configure if none is found. - added --with-included-expat for bundled expat logic. * Rename --enable-debugging to --enable-debug (Mo DeJong). - added NEON_DEBUG macro to exported autoconf macros. * Call progress callbacks for request bodies. * Test changes: - check that reading response headers is a bounded operation. - use a pipe between child and parent to avoid race condition and tedious sleep(). Changes in release 0.15.0: * Major API renaming to use ne_/NE_ namespace: - http_ to ne_, HTTP_ to NE_, dav_ to ne_, DAV_ to NE_, neon_ to ne_ - hip_xml_ to ne_xml_, HIP_ELM_ to NE_ELM_, HIP_XML_ -> NE_XML_ - sbuffer_ to ne_buffer_ - DEBUG() to NE_DEBUG(), DEBUG_ to NE_DBG_ * Type renames: - http_req to ne_request - sbuffer to 'ne_buffer *' * Note, 'ne_buffer' is not an implicit pointer type, you must specify the '*' now, e.g. 'ne_buffer *buf = ne_buffer_create();'. * ne_buffer is no longer opaque. - ne_buffer_data() removed: use buf->data instead. - ne_buffer_size() is a macro. * Header renames and additions: - http_request.h -> ne_request.h - Session code split into ne_session.h - hip_xml.h -> ne_xml.h, nsocket.h -> ne_socket.h, http_utils.h -> ne_utils.h - neon_md5.h -> ne_md5.h, dav_207.h -> ne_207.h - http_basic.h and dav_basic.h merged into ne_basic.h * New functions: - ne_token and ne_shave, to obsolete split_string, shave_string. * Removed: ne_get_request_headers(). * autoconf changes: - disable building shared neon library by default. - option --enable-libxml is replaced by --with-libxml1 and --with-libxml2 to force use of a particular parser. * Fix auth code to only take MD5 digests of response body blocks when necessary (thanks to Kai Sommerfeld). * Fix alignment bug in MD5 code which could cause SIGBUS on Sparc architectures (Kai Sommerfeld). * Rewrite of request body handling: - ne_set_request_body_fd replaces _stream, using an int fd rather than a FILE *. - added ne_set_request_body_provider to give a callback which is called to provide request body blocks. - removal of 'use_body' hook in favour of 'ne_pull_request_body' function to allow hooks to manually read the request body. - ne_{put,get,post,put_if_unmodified} all take an integer fd rather than a FILE * stream. * Test changes: - added framework for testing "over the wire" (fork a server process) - added tests for response message length handling, chunked responses, header folding, sending request bodies. - start at listing RFC2616 requirements and whether they are met or not in test/STATUS. - test for MD5 alignment bug on Sparc (thanks to Kai Sommerfeld). Changes in release 0.14.0: * Add C++ inclusion safety to http_auth.h (Kai Sommerfeld). * Define ssize_t on Win32. (Kai Sommerfeld). * Add C++ inclusion safety to dav_locks.h and ne_alloc.h (thanks to Gregor Bornemann <Gregor.Bornemann@germany.sun.com>). * Significant API change to properties code, to allow use of allprop and complex properties: - dav_propfind_set_complex and _set_flat are removed. - add parameter to dav_propfind_named to take the list of property names to be fetched. - new function dav_propfind_set_private to set private callback. - all properties not handled by caller are stored as flat properties. * Untested: add basic SOCKSv5 support: configure --with-socks. - please report success/failure to neon@webdav.org * Win32/MSVC build files from Magnus Sirwiö <sirwio@hotmail.com>. * Fix for expat detection from Shane Mayer <shanemayer42@yahoo.com>. * Namespace-protect md5 code and more. - md5_* -> ne_md5_* - ascii_to_md5 -> ne_ascii_to_md5 (and moved to neon_md5.h) * Parse authinfo segment in URIs (Johan Lindh <johan@link-Data.com>). - added 'authinfo' field to struct uri. * New API: hip_xml_get_attr to retrieve attributes. * Store language for properties, access with dav_propset_lang. - only if property is defined on the property element itself. * Started a simple test suite (test/*). - includes some simple HTTP server tests. * Remove "Content-Length: 0" header for request with no body, fixing interop with Squid 2.3-STABLE1 (thanks to Kai Sommerfeld). * http_parse_statusline skips leading whitespace. (Johan Lindh). * Partial fix for timezone/date parsing problems. Changes in release 0.13.0: * Fix ne_strndup allocating one byte less than it should (Kai Sommerfeld) - if you use uri_parse, this bug may have caused subtle memory corruption in your application. * Revert API changes in 0.12: property values are not UTF-8 encoded/decoded internally. (thanks to Greg Stein) * Add another optional argument to NEON_BUNDLED macros, actions to be run if bundled build is *not* selected. * API change: added argument to http_add_hooks to register cleanup function for the cookie. * Removed dav_lock_unregister in favour of automatic cleanup when session is destroyed. * Fixed leaks in redirect code (Kai Sommerfeld). * Fixed crashes in hip_xml_destroy (Kai Sommerfeld). * Redirects to a different hostname/port/scheme are never followed: the request will fail with HTTP_REDIRECT instead. Redirect notification callback is only called for *followed* redirects. New API: http_redirect_location() for retrieving location of last redirect. * Authentication is now implemented as a hook, independently of http_request.c: - API change: removed 'hostname' argument from auth callbacks. - API change: you must now include http_auth.h from your application. - Also fixes case of using server and proxy authentication simultaneously * Added 'http_forget_auth' to clear authentication session. * New API: http_session_hook_private for retrieving private per-session cookie for hooks. * API change: http_set_request_body_stream has a return error value. * API change: http_set_request_body_buffer now takes the buffer length too. * New API: caller-pulls interface for reading response body: http_begin_request, http_end_request, http_read_response_block. An alternative to using the (much simpler) http_request_dispatch. * Make --disable-webdav build work. * New API: dav_propnames for retrieving property names. * New API: dav_propfind_get_request to access request object of handler. * API change: progress and connection status callbacks implemented at http_request.h level. Socket-level status callbacks removed, progress callbacks made per-socket. * Supports new expat (Sam TH <sam@uchicago.edu>) * Supports libxml2 (in preference to libxml1). * API change: added namespace protection to base64 and dates functions: all have ne_ prefix now. * Fixed ranged GETs where a specific range is requested (Johan Lindh <johan@linkdata.se>). * Limit number of response header fields to 100. * Allow requests for the '*' URI even if a proxy server is in use. * libxml: Get useful error messages for parse errors. Changes in release 0.12.0: * Portability fixes to http_request.c and http_auth.c. - fixes digest auth on big-endian architectures. * Fix warnings from stray tokens after #endif's in uri.h and string_utils.h. * Add C++ inclusion safety to http_redirect.h (Kai Sommerfeld <kai.sommerfeld@germany.sun.com>). * Make redirects to a different host work (Kai Sommerfeld). * Fix reading response bodies when non-chunked and no Content-Length (Kai Sommerfeld). * API change: 'http_add_hooks takes a 'const' request object. * Fixed memory leaks in session hooks (thanks to Kai Sommerfeld). * Fix passing NULL props argument to dav_simple_propfind, to support allprop requests. **** MAJOR INTERFACE CHANGE **** - URIs passed to http_request_create() are NOT escaped by neon. You MUST do this yourself to remain HTTP compliant, using e.g. uri_abspath_escape. (Kai Sommerfeld) * Added --disable-webdav flag to configure, to disable DAV support in the library. This allows building neon without an XML parser. * Corresponding NEON_WITHOUT_WEBDAV macro for use in bundled builds. * Fix Makefile dependancies. * A bundled neon directory builds or doesn't build automatically (i.e. you recurse into it unconditionally). * API clarification: - dav_propset_status may return NULL if the server does not return a response for the given property (issue is open for debate). * API change up for debate: - Property values to dav_proppatch are UTF-8 encoded internally. - Property values in dav_propfind_* are UTF-8 decoded internally. * API additions: ne_realloc, ne_utf8_encode. Changes in release 0.11.0: * Added SSL client certificate support with 'sock_set_client_cert'. - Supports certs in PEM-encoded files. - Specify a callback for prompting the user for the password with sock_set_key_prompt. * Added 'ne_oom_callback', to register a callback which is used if malloc() returns NULL. (Mike Rosellini <m@icopyright.com>) * Register appropriate callback with libxml to handle <![CDATA blocks as normal character data (fixes PROPFINDs against sharemation.com). * Added 'NEON_REQUIRE' macro to declare that you require a neon library of a given minimum version, e.g. NEON_REQUIRE(0,10) means "I need neon 0.11 or later". The _BUNDLED macros will fall back on the bundled copy if an external library is found which is not of a new enough version. * Added neon_version_minimum() function call for run-time version detection. * neon_config.h has been removed. * Use closesocket() to close sockets on Win32 (Markus Fleck <fleck@isoc.de>). Changes in release 0.10.1: * Default expect-100 to OFF. Changes in release 0.10.0: * hip_xml API changes: - The search for a handler for a new child element begins at the handler of the parent element, and carries on up the stack. (previously, it always started from the base of the stack) - Documentation written: doc/parsing-xml.txt * Remove memory leaks and tidy debugging output in new properties code. * API changes to DAV locking interface: - New function: dav_lock_copy to copy a lock object. - Re-ordered arguments to callback of dav_lock_discover, and made the lock object passed back const. - Fix leaks and crashes due to vague interface definitions. * API change to dav_propfind_set_complex: use a callback to return the 'private' structure. * NEON_NORMAL_BUILD and NEON_LIBTOOL_BUILD macros defined for setting up neon's Makefile in a bundled build: see macros/neon.m4. * NEON_VPATH_BUNDLED macro added which takes separate srcdir and builddir arguments for supporting VPATH builds (thanks to Peter Moulder <pjm@bofh.asn.au>). * Added optional final argument to NEON_(VPATH_)BUNDLED, which gives a set of actions to be run if the bundled build is chosen. * NEON_SSL checks for OpenSSL in /usr too. * API change: when using http_session_decide_proxy, it MUST be called before using http_session_server to prevent the DNS lookup on the origin server being optimised out. The real scheme in use is passed to the callback now. * New function, dav_207_ignore_unknown, to ignore any unknown XML fragments in the 207 response. Used by properties layer. Changes in release 0.9.2: * Fix using both dav_propfind_set_complex and dav_propfind_set_flat with the same propfind_handler. Changes in release 0.9.1: * dav_propfind interface - Guarantee that the 'private' structure will be initialized to zero on creation. - Make it the *callers* responsibility to free() the private structure. * Fix a few arguments/variables which mirrored globally declared symbols. Changes in release 0.9.0: * Removed old dav_propfind_* interface, replaced with a better, more powerful, and easier to use interface: - 'dav_simple_propfind' interface for just fetching "flat" (byte-string) properties. - 'dav_propfind_*' interface for fetching flat and/or "complex" (structured XML) properties. - Lets you retrieve the 'status' information, to see what happened if fetching the property failed (e.g 404 Not Found). * Fixes to doc/using-neon.txt (thanks to Greg Stein). * Allow building when srcdir != builddir (Mo DeJong <mdejong@cygnus.com>) Changes in release 0.8.1: * Fix segfault in PROPFIND code. Changes in release 0.8.0: * Fix for using COPY/MOVE over SSL (thanks to David Sloat). * Fix for using a proxy server and SSL. * Added 'http_get_scheme' API call. * Added 'http_redirect.h' to list of installed headers (thanks to everyone ;). * Changes for building on Windows (Peter Boos <PediB@colorfullife.com>) * Fixes for building on BeOS (Sam TH <sam@uchicago.edu> and David Reid <dreid@jetnet.co.uk>). * Add buffering to socket code for pre-BONE BeOS systems (David Reid). * Interface changes for hip_xml: - Renamed hip_xml_add_(mixed_)handler to hip_xml_push_(mixed_)handler - Documentation updates. - Added HIP_ELM_UNUSED for lowest element id which should be used. *** MAJOR INTERFACE CHANGE *** - Removed 'http_status *' pointer from http_request_dispatch. - Added http_get_status(req) to retrieve the response-status information instead. You don't have to declare an http_status object yourself now. * Similarly, added DAV_ELM_207_UNUSED for lowest element id which should be used by users of dav_207_* code (incl. use of dav_propfind_* code). * New NEON_* autoconf macro interface: - Use NEON_BUNDLED if sources are bundled, otherwise NEON_LIBRARY. - The NEON_XML_PARSER macro is NOT called automatically. You must call this yourself if using NEON_BUNDLED; see doc/using-neon.txt for details. * Fix use of 'socket' in nsocket.h function prototypes (Greg Stein). * Remove extra backslash at line 69 of src/Makefile.incl (Dirk Bergstrom). * Examples directory is now a separate package. Changes in release 0.7.7: * Another fix for linking against a libtool-built expat (Greg Stein). Changes in release 0.7.6: * Better check for closed SSL connection after doing SSL_peek. (thanks to Jeff Costlow <j.costlow@f5.com>). * Attempt at correct sock_block() implementation for SSL. * sock_peek() will return SOCK_CLOSED correctly. Changes in release 0.7.5: * Fixed workaround for linking against a libtool-built expat (Greg Stein). Changes in release 0.7.4: * Fix for fd leak on connect failure (David Sloat <d.sloat@f5.com>). * Fix for Digest auth against IIS5 (David Sloat). * Workaround for linking against a libtool-built libexpat.la (Greg Stein). Changes in release 0.7.3: * Check for -lsocket and -linet in configure. * Workaround for SSL problems. Changes in release 0.7.2: * Define SHELL in Makefile (thanks to Eric Mumpower <nocturne@arepa.com>). * Added 'all' target to Makefile (Greg Stein <gstein@lyra.org>) * Added '--with-expat' argument to configure (Greg Stein) * Added 'dav_propfind_destroy' function. Changes in release 0.7.1: * Don't register response body/header authentication callbacks if no credentials-supplying callback has been registered (speed optimisation). Changes in release 0.7.0: * Deprecated use of 'NULL' to http_add_response_header_handler. New interface, http_add_response_header_catcher, to register a callback which is passed ALL response headers regardless of name. * Speed optimisation (~10%?): storing response-header handlers in a hash table for faster look. * New SBUFFER_CAST() macro for getting to the 'char *' of an sbuffer as fast as possible. Changes in release 0.6.1: * Fix for retrying request if connection is closed by server. * Make redirect hook work for >1 request per session. Changes in release 0.6.0: * New interface to allow following HTTP redirects (301/302 responses). A callback must be given to get user confirmation if the request method is not GET, HEAD, or PROPFIND. * New interface to determine whether the proxy server should be used for a given request: http_session_decide_proxy. * Fix nget build again. Support automatic redirects in 'nget'. * Add --with-extra-includes and --with-extra-libs configure parameters to point configure at Changes in release 0.5.1: * Prevent segfault if USE_DAV_LOCKS is defined, and a locking session is not registered (thanks to David Sloat). Changes in release 0.5.0: * Rename xmalloc, xstrdup etc to ne_malloc, ne_strdup etc. * Some speed optimisation in response-header reading. * Use 'off_t' rather than 'size_t' in sock_progress callback, sock_readfile_blocked, and sock_transfer. Changes in release 0.4.2: * Fix for sending request bodies after getting 100-continue response. Changes in release 0.4.1: * Fix nget build. Changes in release 0.4.0: * Install library headers into .../include/neon not .../include/libneon * Install all necessary library headers. * Compile support for WebDAV locking throughout the library * Rename md5.h to neon_md5.h (avoids conflict with md5.h in OpenSSL) * Rename socket.h to nsocket.h (avoids possible conflict with C library) * Update licensing notice on macros/neon*.m4: note that these files are NOT under the LGPL, and can be used in other packages regardless of the license the package uses. * Update NEON_LIBRARY m4 function to allow optional specification of names of bundled neon/expat source directories. * Increase socket read timeout to 60 seconds. * Added an POST method: from Sander Alberink <sander.alberink@cmg.nl>. * Added 'http_get_request_headers' to return the sbuffer containing all request headers. * Allow passing NULL as name to http_add_response_header_handler: the handler callback is passed the entire header string, of ALL response headers. Changes in release 0.3.1: * Compile fix for dav_locks.c (thanks to Paul D'Anna) Changes in release 0.3.0: * Rewrite of socket handling layer. All sock_* functions changed. * Added basic SSL support: --with-ssl (requires OpenSSL). NOTE: Certificates are NOT presented for verification. * 'nget' accepts URL's using the 'https' scheme. * New example program, 'nserver', to display the Server: string, e.g. 'nserver https://www.eu.c2.net/' * Fixed request re-send when persistent connection times out. * "Hooks" support: allow external hooks into the HTTP request/ response dispatch loop. * New printf-style interface for adding request headers. * Make symbols used in header files C++-safe (Tom Bednarz). * WebDAV locking support: lock discovery, LOCK (exclusive/shared) UNLOCK. "If:" headers are sent as appropriate. Simple interface for implementors of new methods to indicate which locks are required for the method. * Primitive HTTP cookies support. * Primitive hack at a GNOME-based GUI example program "nbrowse". Enable build with --enable-gnome-examples. It crashes, and not much else. Requires GNOME and POSIX threads. Example usage: 'nbrowse dav.ics.uci.edu /msdav/' Many thanks to Lee Mallabone for Gtk help, and showing how to use Gtk and threads. Changes in release 0.2.0: * Use libtool: new configure options to select whether to build shared and/or static libraries. Should build shared libraries portably now. * Complete rewrite of the hip_xml interface to use opaque pointers. New functions: hip_xml_create, hip_xml_destroy: create parser. hip_xml_{set,get}_error: Access to error string. hip_xml_add_handler: Register callbacks for a set of elements. hip_xml_valid: Returns whether the parse was valid or not. Removed functions: hip_xml_init, hip_xml_finish. * Removed functions made reduntant by above changes in dav_207. * Don't include config.h in header files * Fix PROPFIND allprop request body (Michael Sobolev) * Added C++ safety macros around header files. * Added neon-config script for getting correct CFLAGS and LIBS values for using libneon in applications.
