configure: Add spectre variant 2 mitigations --enable-hardening adds -mfunction-return=thunk and -mindirect-branch=thunk compiler options if supported.

charset-alias-plugin

imap: support for FETCH SNIPPET

configure: Switched version number to 2.4.devel

stats: Add new stats service

global: Renamed stats plugin and service to old-stats

Implemented SMTP submission proxy service.

configure: --with-sodium doesn't add support for scrypt (for now, at least)

configure: Detect --whole-archive in linker

configure: Fix Lua conditionals

configure: Drop LuaJIT support Does not work with our custom allocator

lib-lua: Add lua helper library Provides a base lua library for lua extensibility

configure: Detect lua

configure: Fix writing LIBDOVECOT[_DEPS] in dovecot-config It needs to be in a single line or DC_DOVECOT's greping doesn't work correctly.

configure: Add support for EXTRA_LDFLAGS

m4: Use AC_C_BIGENDIAN instead of custom m4

configure: Detect libsodium presence

m4: Add PRIdTIME_T and PRIxTIME_T format specifiers

dict-ldap: Move from plugins/dict-ldap to lib-dict-backend

lib-dict: Move libdict_backend to lib-dict-backend

lda/lmtp: Parse SMTP submit settings.

configure.ac: Wrapped long LIBDOVECOT_LA_LIBS definition line to make modifications easier.

configure: Fix link order: libsmtp depends on libprogram-client

configure: Check for getrandom

apparmor: Add apparmor plugin It lets dovecot temporarily switch to a new apparmor context for a user.

lib: remove support for Boehm GC There were several issues with our usage of Boehm GC: - it didn't help with memory fragmentation - it is not very efficient - it was rarely enabled & used Proper use of a GC would involve radical changes to how we write code and cause portability issues. We can get most of the benefits of a GC with data stacks and alloc-only memory pools.

notify-status: Add notify-status plugin This enables updating a dictionary with mailbox status information when the mailbox changes. It requires notify_status_dict setting for specifying the dict where the data is stored. One can optionally use notify_status_mailbox patterns for specifying which box(es) the status update is done. Subsequent patterns are notify_status_mailbox2 and so forth. One can also specify data format using notify_status_value plugin setting.

lib: include inttypes.h to get PRIu64 & friends Including it in lib.h allows all of the Dovecot code (as well as any external plugins) to just use these macros without worrying about what system headers to include.

configure: Remove --with-storages parameter Just compile all the storages, since the only benefit in limiting them is to save a tiny bit of disk space. The recently added imapc quota code fails to link if imapc storage isn't compiled in. This is the simplest way to fix that.

var-expand-crypt: Encryption/decryption support for var-expand Registers new encrypt and decrypt processors for var-expand.

lib-oauth2: Add support library for OAUTH2

configure: Link libsmtp before libdns Fixes linking LIBDOVECOT when using .a libraries

lib-lda: Moved LMTP client to lib-smtp. This makes the LMTP client available without dependency on lib-storage. For Dovecot v2.3, the newly created lib-smtp will evolve into a full client/server SMTP implementation. That will then remove the remaining SMTP code from lib-lda.

configure: Define __STDC_LIMIT_MACROS for CXXFLAGS Fixes SIZE_MAX being undefined when building fts-lucene.

configure: Moved pandoc check to m4/dovecot.m4

mail-crypt: Add mail-crypt plugin

configure: Fix link ordering libprogram_client.la needs to be before libdns.la

configure: Detect pandoc for building documentation

lib-program-client: Add program-client from pigeonhole

configure: hardening logic is backwards Before this change, the argument parsing was busted. The --help string only compounded the incorrect behavior by suggesting that --disable-hardening could take a yes/no argument. | before | after ------------------------------+----------+-------- <no option> | enable | enable --enable-hardening | disable | enable --enable-hardening=yes | disable | enable --enable-hardening=no | enable | disable --disable-hardening | enable | disable --disable-hardening=yes | error | error --disable-hardening=no | error | error

configure: Added --enable-static-checker parameter

configure.ac: Forgot to invoke DOVECOT_WANT_VPOPMAIL. It was thereby impossible to enable Vpopmail support.

Moved cc-wrapper.sh handling to dovecot.m4 When configuring Dovecot --without-shared-libs and pointing external plugins to uninstalled sources --with-dovecot, any binaries complied for plugins weren't using cc-wrapper.sh, which could have caused runtime failures when they attempted to load plugins dynamically. Now it's possible to add DC_CC_WRAPPER to plugins' configure.ac to build with the cc-wrapper.sh.

dovecot: Remove ssl-params

configure: Check for hardening flags

configure: Check if C99 "static" keyword is supported for array sizes.

Added welcome plugin.

ldap: Fix cyclic dependency

print CFLAGS on ./configure

configure: Include lib-dcrypt in core

lib-dcrypt: Initial implementation

imap: Implemented support for the LITERAL- capability. This replaces the LITERAL+ capability when the imap_literal_minus setting is enabled.

lib: Use arc4random if present

lib: Do not use OpenSSL to read random bytes

lib-dovecot: Avoid duplication of listing *.la in both Makefile.am and configure

Split parts of lib-dict into lib-dict-extra. Otherwise there's a circular dependency because lib-dict/dict-fs.c depends on lib-fs, while lib-fs/fs-dict.c depends on lib-dict. This becomes a problem when compiling --without-shared-libs, although for some reason it works for me while linking the Dovecot core, but not when linking external plugins.

configure, Makefile: Tell autoconf/automake about m4 directory To finally get rid of the complaints: libtoolize: Consider adding 'AC_CONFIG_MACRO_DIRS([m4])' to configure.ac, libtoolize: Consider adding '-I m4' to ACLOCAL_AMFLAGS in Makefile.am.

configure: Move checks to separate m4 files

Require IPv6 to build

lib: Implement utc_mktime() with timegm() if it exists. It should be more efficient than repeatedly calling gmtime() many times.

configure: Fixed building lib-ldap / dict-ldap --with-ldap=plugin

configure: Switched version number to 2.3.devel

configure: Add lib-ldap

configure: Changed version number to v2.2.devel. The actual version numbers live only on the release-branches from now on.

configure: Minor cleanup - avoid code duplication.

dovecot-config: Fixed setting LIBDOVECOT_LIBFTS[_DEPS]

Released v2.2.20.

Released v2.2.20.rc1.

dovecot-config: Added LIBFTS.

Released v2.2.19.

Released v2.2.19.rc2.

Released v2.2.19.rc1.

Added push-notification plugin

Removed all invocations of strtoll() and friends.

Added imap-hibernate process for gathering IDLEing imap processes. imap_hibernate_timeout setting controls how quickly the connection is moved from imap process to imap-hibernate process. Some IMAP extensions like NOTIFY, SEARCH=CONTEXT and COMPRESS aren't supported yet. There's also a new X-STATE command, which can be used to export the current IMAP connection state to a string and later on imported to get back to the original state (a quick resync feature for IMAP clients). However, this command is disabled for now due to the current code being unoptimized for untrusted input.

Removed support for dnotify. Everybody should be using inotify by now.

Released v2.2.18.

configure: Use consistent quotation for AC_DEFINEs as per autoconf recommendations. Also fix one minor typo.

Released v2.2.17.

Added quota-clone plugin.

Released v2.2.17.rc2.

lib-sql: Added support for Cassandra CQL as lib-sql backend. Implemented using DataStax's cpp-driver. Many things are still unimplemented. Column name specific functionality isn't even supported by the Cassandra library. So this can currently mainly be used as one of the dict backends for some simple functionality.

Released v2.2.17.rc1.

Moved fs-compress to a separate plugin directory. Mainly because I couldn't figure out how to make automake dependencies work on "make install" stage. It was trying to link fs-compress.so using -ldovecot-storage, but libdovecot-storage.so was also concurrently being installed.

imap: Don't advertise SPECIAL-USE if there are no such mailboxes configured.

configure: When compiling with sqlite3, don't forcibly link with zlib. Looks like -lz was originally added when it was copy&pasted from some other code. Hopefully this isn't actually needed by any (current) system.

configure: s/normalizer/libicu/ since we it could be used for something else as well.

lib-fts requires libexttextcat actually - don't even try to use textcat for it. I'm also not sure yet if some libexttextcats are too old for it.

configure: Fixed building without textcat.

configure: Added Debian Wheezy workaround for finding textcat.h

lib-fts: Fixed default textcat datadir paths.

configure: Fixed linking with libexttextcat when it was found via pkg-config

Initial import for lib-fts. Parts of what this code does was already implemented internally by fts-lucene. lib-fts is intended to be usable for all the FTS backends. The APIs are still going to change a bit, but hopefully not after v2.2.17 release. Mostly written by Teemu Huovila.

configure: Fixed/improved finding and using libexttextcat. libexttextcat wasn't actually being used at all by fts-lucene. Now we'll first prefer finding it via pkg-config, next finding exttextcat and only last look up textcat.

configure: Stemmer and textcat checks are now done even if CLucene isn't used. They'll be useful for other FTS backends as well. This patch doesn't change any actual functionality.

configure: Added --with-textcat parameter

configure: Add missing (auto) to autodetected options.

Released v2.2.16.

dict: cdb support should be available only to dict process. Because otherwise we need to link libcdb into pretty much all Dovecot binaries, which is part of what having the dict proxy tries to avoid. We could implement the direct linking optionally as well, but that would need to be done in a bit more generic way rather than just hardcoding it only to cdb support.

Released v2.2.16.rc1.

stats process/plugin redesign to be more modular. The visible functionality doesn't actually change with this patch yet, but it allows other plugins/services to add their own fields to stats process. For example auth process could send auth success/failures or auth cache hits/misses.

configure: Removed unnecessary lines left by the previous commit.

Link all libstorage.la dependencies into the library itself instead. Instead of keeping a lot of different libraries in LIBDOVECOT_STORAGE, which have circular dependencies and may cause linking issues.

dovecot.m4: External plugins can now more easily run their tests via Valgrind. DC_DOVECOT macro automatically adds RUN_TEST variable to Makefiles, which can be used to call any test programs. If valgrind exists, the tests are run through it. This is done by writing run-test.sh to the build directory, so the original run-test.sh in hg is no longer needed.

configure: Don't break when using --without-shared-libs and CC with '/' chars.

Released v2.2.15.

Released v2.2.14.

Released v2.2.14.rc1.

Install libdovecot-dsync.so library, which can be used separately.

last-login plugin: Added missing configure and Makefile entries.

configure: Don't actually run the test to see if inotify works. It's definitely no longer needed in modern Linux systems and the test itself can also unintentionally fail sometimes.

lib: Changed hash_table_remove() "key not found" panic to be in a macro itself. This makes it much easier to find out where such crashes are coming from. Since this breaks the ABI in such a many places the ABI version number was increased immediately..

Released v2.2.13.

Released v2.2.13.rc1.

Released v2.2.12.

Released v2.2.11.

lib-compression: Added initial support for LZ4 There's no standard file format for LZ4, so we created our own. The code has had only minimal testing currently, so there may be bugs.

Released v2.2.10.

mysql: Added ssl_verify_server_cert=no|yes parameter. To make sure we don't break existing installations, default to "no". For v2.3 it should default to "yes". Patch by Gareth Palmer

Released v2.2.9.

lib-compression: Added support for liblzma (xz) Annoyingly this is mainly copy&pasted [io]stream-bzlib, but I'm not sure if it's worth the effort to try to create common functions for them.

Added mail-filter plugin.

Released v2.2.8.

Released v2.2.7.

configure: Added mdbox_deleted storage.

Released v2.2.6.

Released v2.2.5.

Released v2.2.4.

Released v2.2.3.

Added initial libsasl for implementing client side SASL library. Initially supports PLAIN and LOGIN mechanisms.

Released v2.2.2.

configure: Fixed checking for struct sockpeercred with OpenBSD <5.3

OpenBSD compile fix: include sys/socket.h when checking for struct sockpeercred.

Released v2.2.1.

Released v2.1.0.

Released v2.2.rc7.

Released v2.2.rc6.

Released v2.2.rc5.

Released v2.2.rc4.

Released v2.2.rc3.

Released v2.2.rc2.

configure: Fixed plugins when compiling --with-shared-libs

Released v2.2.rc1.

Reverted the recent hash.h changes. Instead use -Wno-duplicate-decl-specifier with clang. The modified version required hash table users to know the structs' contents, which isn't otherwise necessary.

MODULE_LIBS is now part of LIBDOVECOT. No need to explicitly link it everywhere.

configure: Fix previous commit & implement AC_C_TYPEOF ourself. RHEL5's autoconf was old enough to not have AC_C_TYPEOF.

configure: Removed accidentally enabled clang -fsanitize options for now.

Replaced all -1U and (unsigned int)-1 with UINT_MAX. It's somewhat clearer this way. Also clang's -fsanitize=integer gives runtime errors about -1U (but not about explicit casts, so no need to change (type)-1 casts).

Use proper HAVE_TYPEOF check instead of checking with gcc versions.

quota-fs: Support NetBSD 6.0 libquota. Patch by Emmanuel Dreyfus.

Released v2.2.beta1.

fts-solr: Use built-in lib-http instead of libcurl. Removed libcurl dependency.

dict: Added support for cdb backend. Based on patch by Hleb Valoshka.

dovecot-config: Removed unnecessary/duplicate ssl library links.

Released v2.2.beta1.

configure: Use pkg-config with clucene if available.

configure: Use -lrt for check_gettime() only if needed.

Added libhttp to libdovecot.so

Reverted 269104a0821b (Build imapc and pop3c always as plugins.) This is no longer needed now that lib-ssl-iostream can be linked without linking openssl.

lib-ssl-iostream now dynamically loads openssl library instead of linking to it. This allowed removing the separate libdovecot-ssl library. In future if GnuTLS/NSS support is added it would also allow switching between them dynamically.

Released v2.2.alpha1.

If prefix="" namespace isn't defined, autocreate it as an unusable namespace. This avoids having to handle mail_namespace_find() errors all over the place. Instead now the mailbox accesses will simply fail.

Renamed configure.in to configure.ac. Apparently automakes in future won't support configure.in anymore.
