Partially implemented IMAP SEARCH=X-MIMEPART capability. This capability is currently Dovecot-specific.

dbox: Optimize POP3 MAIL_FETCH_UIDL_BACKEND. We keep track of the highest UID known to have POP3 UIDL in index's header. If saving adds a newer message, it'll also update the header. When fetching UIDL_BACKEND, we can need to check only mails with lower UIDs. There are some race conditions here, but normally UIDLs are set only once during migration so it shouldn't matter.

lib-storage: Update mailbox vsize header on save/copy/expunge. This allows always efficiently looking up maiboxes' vsizes after they're initially calculated. The expunge handling is unfortunately done currently in quota handling code, so it works only if quota is enabled. Ideally this would be solved in v2.3 with some lib-storage core changes.

lib-storage: Moved index/index-mailbox-check.c code to mailbox-watch.c This changes the API, but adds backwards compatibility macros.

lib-storage: Moved mailbox vsize calculation code to its own file. No functional differences.

lib-storage: Added support to get/set/iterate mailbox attributes. The attributes are stored in a dict specified by mail_attribute_dict setting. The idea is to use this as storage for extensions that require per-mailbox key=value pairs, such as METADATA.

lib-storage: Moved dbox-sync-rebuild API to more generic index-rebuild.

IMAP BINARY extension supports now FETCH BINARY command.

Renamed istream-attachment to istream-sized. The code didn't really assume anything about the input being an attachment, so this allows reusing the stream for other purposes.

shared mailboxes: Per-user flags can now be stored in private index files. This can be enabled by adding e.g.: mail_location = mdbox:/var/shared/mdbox:INDEXPVT=~/mdbox/shared

Makefile: Link with SSL_LIBS whenever linking libssl_iostream.la

lib-storage: Added initial support for pop3c backend.

lib-storage: Verify that cached message size matches actually read size.

lib-storage: Index search context is now more accessible by backends. Moved struct index_search_context to index-search-private.h and added recheck_index_args flag that backends can set.

Added initial implementation of "imapc" storage. It can be used to create a "smart IMAP proxy" where Dovecot uses remote IMAP server as a mail storage. This is a very rough early implementation. Performance isn't good, many required features are missing, error handling is lacking and code needs de-uglification. Still, it should be enough for selecting INBOX and accessing mails in it.

lib-storage: Unvirtualized some methods from struct mailbox. There was never any point in overriding or hooking into them.

lib-storage: Added support for saving mail attachments separately via filesystem API. Currently this works only with sdbox and mdbox backends.

configure: Removed --enable-header-install. It's now always enabled. There didn't seem to be much point in keeping it optional anymore. They're now more useful than before because shared libraries are also installed. --HG-- branch : HEAD

If valgrind exists, run unit tests using it. If valgrind prints any errors, fail the test. --HG-- branch : HEAD

Split dbox (single-dbox) and mdbox (multi-dbox) into separate storage backends. This cleans up the code, makes it faster and also fixes some bugs. Super-fast maildir migration code was also dropped, at least for now. --HG-- branch : HEAD

Makefiles: Changed check-test to depend on all-am to fix build dependency problems. --HG-- branch : HEAD

Added unit test for mailbox_get_expunges(). --HG-- branch : HEAD

Flattened header namespace on install. --HG-- branch : HEAD

struct mail_private now contains all kinds of statistics about file accesses. --HG-- branch : HEAD

Build libdovecot.so and libdovecot-storage.so. Based on patch by Stephan Bosch. --HG-- branch : HEAD

Added initial support for shared mailboxes. Listing isn't supported yet. Each user gets their own hidden namespace created automatically when they're accessed the first time. --HG-- branch : HEAD

Rewrote thread indexing code. It's a lot simpler and takes less disk space. We no longer try to keep a hash table and the entire thread tree stored on disk. Instead we keep a simple Message-ID string (actually just "uid, ref#" pointer) -> unique index number mapping on disk, read it to memory and use it to build the thread tree. After the initial build the thread tree is still updated incrementally. --HG-- branch : HEAD

Thread index fixes and optimizations. --HG-- branch : HEAD

Moved non-syncing related search result updating code to a separate file and did some other cleanups. --HG-- branch : HEAD

Message sort index handling rewrite to fix several race conditions when multiple processes are sorting at the same time. Also fixes sorting to work correctly with 64bit timestamps and file sizes. --HG-- branch : HEAD

Moved threading code to lib-storage. --HG-- branch : HEAD

Implemented CONTEXT=SEARCH extension. --HG-- branch : HEAD

Added raw storage for opening single-mail files/streams as mailboxes. --HG-- branch : HEAD

Added index-sync-changes.[ch] --HG-- branch : HEAD

Added a simple cydir mail storage backend. It trusts index files completely: if the indexes are gone, the mailbox starts completely empty and overwriting the existing mail files. So probably not a good idea to use this in production yet. --HG-- branch : HEAD

Added --with-headers configure option to install .h files. --HG-- branch : HEAD

Changed mail-storage API to do the mail sorting internally. Optimized it internally to keep a 32bit sort_id field in index for each used primary sort condition. Practically this should mean less disk I/O, memory and CPU usage when SORT command is used. --HG-- branch : HEAD

Initial implementation of Dovecot's own high performance file format, named dbox. Currently relies heavily on index files to work, and isn't able to rebuild them if they're lost. This will be fixed soon. Not tested much yet in general. --HG-- branch : HEAD

Upgrades to autoconf 2.5 and automake >1.4. --HG-- branch : HEAD

importing new index code. mbox still broken. --HG-- branch : HEAD

Changed how cached headers are stored. Previously when we added new headers, all the old headers were duplicated as well which wasted space. Also fixed several bugs in caching. --HG-- branch : HEAD

missing index-expunge.h --HG-- branch : HEAD

cleanup: message saving code isn't index-specific --HG-- branch : HEAD

missing index-mail.h --HG-- branch : HEAD

mail-storage.h interface changes, affects pretty much everything. FETCH, SEARCH, SORT and THREAD handling were pretty much moved from lib-storage/ to imap/ so adding non-index storages would be much easier now. Also POP3 server can now be easily implemented with lib-storage. Not too well tested, and at least one major problem: partial fetching is _slow_. --HG-- branch : HEAD

missing index-sort.h --HG-- branch : HEAD

First implementation of SORT extension. String comparing still not up to spec, so we don't advertise it in capability string yet. The code supports getting the data partially pre-sorted to reduce memory usage and make it faster. So, in future we could use this by creating sorted binary trees. Also moved mail-storage-register.c into it's own .a lib to fix circular dependencies. --HG-- branch : HEAD

mailbox_check_interval setting: Dovecot can notify client of new mail in selected mailbox soon after it's received. This setting specifies the minimum interval in seconds between new mail notifications to client - internally they may be checked more or less often. Setting this to 0 disables the checking. --HG-- branch : HEAD

missing header file --HG-- branch : HEAD

Moved lib-index/mail-messageset.* to lib-storage/index/index-messageset.*. --HG-- branch : HEAD

Added support for caching of MessagePart data. This is useful for fetching body[part]s. Also BODY and BODYSTRUCTURE can be generated fast using it. Also fixed index corruption in some situations when more cached data was added to index. --HG-- branch : HEAD

Initial revision --HG-- branch : HEAD
