global: Fix spelling mistakes in comments Original work by @andreasschulze and @jsoref

lib-index: Replace mail_index_set_log_rotation() with mail_index_set_optimization_settings() This allows more easily adding optimization-related settings.

lib-index: Fix wrong mail_index_modseq_header automatically It happens only on the next sync, although that isn't actually guaranteed to happen. Still, it happens almost always so this should be good enough.

lib-index: Don't ignore mail_transaction_log_move_to_memory() failure

lib-index: mail_transaction_log_file_get_highest_modseq_at() - return error string This can help figuring out why some error happened when more context is provided in the caller's error messages.

lib-index: mail_transaction_log_file_map() - return reason/error string This can help figuring out why some error happened when more context is provided in the caller's error messages.

lib-index: Don't increase modseq for backend/dirty flag changes These flags are used only for internal changes and they shouldn't be triggering any modseq changes. To avoid modseqs from unexpectedly shrinking, the new modseq counting behavior is enabled only for newly rotated transaction log files that have a new minor_version.

lib-index: Add mail_index_set_log_rotation()

lib-index: Limit mmap errors in txn log file to 1/s

lib-index: Improve errors - return reason in mail_transaction_log_file_open()

lib-index: Add more information to "Missing middle file" error.

lib-index: Small improvements to logging the reason for long transaction log lock waits

lib-index: Include reason string in warnings about keeping transaction log locked for too long.

lib-index: Moved MAIL_TRANSACTION_LOG_LOCK_WARN_SECS as part of public API.

lib-index: Handle better race condition there dovecot.index.log and .log.2 are the same link.

lib-index: Log a warning if locking transaction log takes longer than 30 secs.

Typofix: s/TRANSCATION/TRANSACTION/

lib-index: Delete dovecot.index.log.2 files after 2 days, not after 30 mins.

lib-index: Avoid unnecessary pread()s at end of transaction log file. If we've already read until EOF while the file has been locked, there's no need to do it again. Previously this worked while index was being synced, but not while committing a transaction.

lib-index: Don't waste time on every mailbox open checking if .log.2 should be deleted.

lib-index: Log a warning if transaction log lock is kept over 3 minutes.

lib-index: Lock timeout setting wasn't actually used in all places.

Renamed fsync_disable to mail_fsync=optimized|always|never. --HG-- branch : HEAD

lib-index: Added support for undeleting a deleted index. --HG-- branch : HEAD

Added support for marking mailbox index deleted. Don't allow any changes after that. This is going to help with race conditions when deleting mailboxes. --HG-- branch : HEAD

index: Code cleanups. --HG-- branch : HEAD

index: Removed duplication of mail_index_open_flags from struct mail_index. --HG-- branch : HEAD

Added ability to specify message's minimum modseq value. --HG-- branch : HEAD

buffer_create_[const_]data() API change: Take buffer_t as parameter instead of allocating it. --HG-- branch : HEAD

Added mail_index_unlink(). --HG-- branch : HEAD

Fixes to handling "out of disk space/quota" write failures. --HG-- branch : HEAD

Don't give bogus "log_file_tail_offset shrank" errors. --HG-- branch : HEAD

Keep modseqs as 1 until the first modseq ext intro record enables them. Performance should be better again when modseqs are disabled. --HG-- branch : HEAD

Modseqs are no longer calculated from transaction log sequence + offset. Now they begin from 1 and each "visible" transaction increases it by one. --HG-- branch : HEAD

Keep better track of when we need to flush NFS attribute caches. --HG-- branch : HEAD

Renamed __attr_*__ to ATTR_*. Renamed __attrs_used__ to ATTRS_DEFINED. --HG-- branch : HEAD

Changed .h ifdef/defines to use <NAME>_H format. --HG-- branch : HEAD

Replaced MAIL_INDEX_LOCK_SECS usage with cache/index/log specific defines which are common with dotlocks. --HG-- branch : HEAD

Delete over 30 minutes old .log.2 files when opening indexes. --HG-- branch : HEAD

Added support for resetting index. --HG-- branch : HEAD

Handle indexid changes better. --HG-- branch : HEAD

Removed debug #defines and changed log rotation size defaults. --HG-- branch : HEAD

int/ext/mailbox sync offset changes: Combined mailbox and int offsets to "tail" offset and renamed ext offset to "head". This makes it clearer how they're supposed to be used. --HG-- branch : HEAD

Fixes to mail_transaction_log_file_map() error handling. --HG-- branch : HEAD

mail_transaction_log_move_to_memory() can't fail anymore. Moved the code to -log-file.c. --HG-- branch : HEAD

Initial commit for major index file code cleanup. - dovecot.index file isn't anymore required to be updated when syncing. - Getting the latest index file mapping is now done always by reading dovecot.index and then reading the latest changes from dovecot.index.log. - mmap()ing dovecot.index file is slower than reading it, so it's not currently done unless the file is at 256kB. This may change though. - Some things are still broken. --HG-- branch : HEAD

Moved mail transaction log file related code to its own file. --HG-- branch : HEAD

If transaction log grows larger than 1MB, rotate it even if it was created less than 5 minutes ago. --HG-- branch : HEAD

Lock handling changes. Everything goes through file-lock API now and there's only a single enum listing the different lock methods. This change exposed some unneeded (or possibly even wrong?) unlock calls in index file handling which were fixed. --HG-- branch : HEAD

Reference counting fixes. Fixes an assert crash when closing the index. --HG-- branch : HEAD

Code cleanup --HG-- branch : HEAD

Don't leak opened .log.2 transaction logs. --HG-- branch : HEAD

Added "bool" type and changed all ints that were used as booleans to bool. --HG-- branch : HEAD

Minor error checking fixes. --HG-- branch : HEAD

index.log file is now rotated to .index.log.2 file. When log file is missing, it's used if the wanted log is in it. --HG-- branch : HEAD

In-memory indexes work again. Just pass dir as NULL to mail_index_alloc(). --HG-- branch : HEAD

Several transaction log cleanups and fixes. --HG-- branch : HEAD

Moved code into mail-transaction-log-append.c --HG-- branch : HEAD

Changed dotlocking API. --HG-- branch : HEAD

Transaction log file is now read-lockless. --HG-- branch : HEAD

Don't rotate transaction log too often --HG-- branch : HEAD

file_dotlock_open/delete/replace now has lock_suffix parameter. NULL defaults to ".lock". Fixed dotlocking transaction log. --HG-- branch : HEAD

fixes for mmap_disable --HG-- branch : HEAD

Added fcntl_lock_disable setting to allow indexes to work with NFS. Some other locking fixes. --HG-- branch : HEAD

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