The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

I finally like it! - Settled on the LGPL for all of my new code. - Replaced the RSA MD5 implementation with a public domain version. - Documentation updated for the new API. libSieve 2.1.6 -------------- - Added a set of error-retrieval functions. libSieve 2.1.5 -------------- (formerly libsieve 2.2.0_pre3) - CFLAGS now includes -Wall and compiles very cleanly. Messages from lex/yacc are benign. - Namespace cleanups: internal global functions prefixed with "libsieve_" for consistency. - Local regex library, borrowed from GNU glibc 2.3.2. Used under LGPL license version 2.1. - Compiles under Win32 with Visual C++, with many thanks to Brandon Knitter. libSieve 2.1.4 -------------- (formerly libsieve 2.2.0_pre1) - Sieve 2 API has begun. More changes should be expected during the 2.1 series. - All later-CMU code removed and/or replaced; original licensing is now entirely old-CMU style and augmented by the GNU GPL as it is placed on all new code and applies to the distribution as a whole from here forward. - "Poor man's parsers" for RFC 2/822 addresses and message headers replaced with lex/yacc. - Extensive Valgrinding performed to identify memory leaks; no known leaks remain. - Many more changes, amounting to perhaps a 70% rewrite of all code. libSieve 2.1.3 -------------- - Accepted patches from Timo Sirainen: - Added function xstrconcat - Changed strdup to strndup - Changed strcpy to xstrcpy - Changed uglies to xstrconcat - Rebuild .y and .l in Makefile.am - Changed int to size_t where applicable - Added explicit casting where applicable - Accepted patches from Oliver Tappe: - Fixed examples for the web site - Removed useless headers - Now builds on BeOS - Cleaned up lots of K&R style function declarations libSieve 2.1.2 -------------- - Changed `timestamp` to $timestamp in configure scripts. - Added missing autoconf and libtool scripts. - Fixed a typo in index.html libSieve 2.1.1 -------------- - First public release of the libSieve distribution. - com_err library removed. - Conversion to GNU autotools for the build process. libSieve 2.1.0 -------------- - Forked from CMU Sieve 2.1. - SourceForge project site and a new web site and CVS tree and prepared. - Dependencies on libCyrus trimmed to a bare minimum. CMU Sieve 2.1 ------------- - Compliant with RFC 3028. As a result, fileinto and redirect only accept a single string and NOT a string-list. - Compliant with draft-martin-sieve-notify-01. As a result, notify actions will need to be updated to the new syntax. CMU Sieve 2.0 ------------- - Compliant with draft-showalter-sieve-11.txt and draft-showalter-sieve-vacation-03.txt. - Added support for the regex, imapflags, notify and subaddress extensions. See README for references. - Verifies email addresses in redirect and vacation actions are syntactically correct (compliant with RFC822). - Run-time error reporting. - Changed callback interface to use callback contexts instead of individual parameters. Also added an error string buffer for run-time error reporting. - Vacation will not reply to any message containing an "auto-submitted" header containing anything other than "no". CMU Sieve 1.4 ------------- Now included with imapd distribution (hell, why not?). Error returning and recovering: added error recovering to the parser (but not much!) added error messages to the parser Working on error returning and error recovering. run-time errors detect some errors in lexer? Working on even better parsing: verify addresses could be addresses verify mailboxes could be mailboxes verify outgoing headers can be headers CMU Sieve 1.3 ------------- Changed for integration with cyrus deliver. CMU Sieve 1.2 ------------- Added additional callbacks (ok, so I want to make my integration with deliver easier) and envelope and vacation support. Made it compile without libcyrus. It should compile without libcyrus, but then it does not implement the "address" test. That's just too much work to do when I have a neato library to do it for me. Todo: - regex matching CMU Sieve 1.1 ------------- - Updated to draft-showalter-sieve-07bis.txt - Simple API (see sieve_interface.h; currently mostly undocumented) - Implements all of the optional features except "envelope" - Maintains "if it parses, it probably runs" behavior. (Goal: minimize run-time errors.) CMU Sieve 1.0 ------------- - prototype implementation libsieve-2.2.6/Makefile0000644000175000017500000000417210702626165013756 0ustar aaronaaron# this is the version number :-) PACKAGE = libsieve VERSION = 2.2.6 SOURCES = src DOCS = www rfc OTHERS = AUTHORS COPYING NEWS README Makefile all: @echo "This is the top level Makefile, which does three things:" @echo @echo "1.

It is based upon code distributed with the Cyrus Mail Server prior to CMU's switch to a more restrictive license. The libSieve API attempts to be easy to use and extensible, and replaces the more rigid API in the Cyrus Sieve implementation. For questions, comments, and bug reports regarding this library, please contact Aaron Stone directly. There are no mailing lists. The documents listed below coincide with those features currently implemented in libSieve. Both as these documents progress through the standardization process and as libSieve itself matures, additional extensions and later revisions of them will be implemented.
