Updated copyright notices to include the year 2018.

global: Replace o_stream_nfinish() with o_stream_finish() whenever possible

global: Remove unnecessary o_stream_nflush() calls The following o_stream_nfinish() or o_stream_uncork() calls it anyway.

lib-index: Track .log.2 rotation time in index header This avoids unnecessarily stat()ing the file. Also it's a bit better since it's tracking the actual rotation time, not the mtime of what the .log file happened to have at the time of rotation. The initial rotation timestamp is written only to the dovecot.index header without going through dovecot.index.log. This works, because the dovecot.index is written practically always after a log rotation. For the rare cases when it doesn't happen, the dovecot.index.log.2 just gets deleted later after the next log rotation.

lib-index: Make sure an already-corrupted index/log isn't written

global: freshen copyright git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-5]/$1-2016/g;s/ (201[0-5]) Dovecot/ $1-2016 Dovecot/'

lib-index: Removed some unnecessary fields.

lib-index: When writing new index, rotate the log file first before writing it. This way the index contains the new log's seq+offset instead of having to recreate the index almost immediately afterwards.

lib-index: Replaced some unlink()s with i_unlink*()s where we could. This changes some mail_index_set_error() calls to i_error()s, but because these unlink() failures don't actually fail the operation it doesn't matter. In fact it may be even better that it doesn't overwrite the existing index->error if it exists.

global: freshen copyright Robomatically: git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-4]/$1-2015/g;s/ (201[0-4]) Dovecot/ $1-2015 Dovecot/' Happy 2015 everyone! Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib-index: Added path parameter to mail_index_create_tmp_file() This allows using it for creating any kind of a new index file with proper file permissions. Some of the old code should probably be changed to use this. Maybe even move this function to public mail-index.h

Updated copyright notices to include year 2014.

lib-index: Don't bother tracking if header/records were changed. They aren't really needed. When mail_index_write() is called, we already know we want to update the index.

Oops :) Update copyrights to 2013 without breaking all .c files.

Updated copyright notices to include year 2013.

Make sure we check all the functions' return values. Minor API changes to simplify this. Checked using a patched clang that adds attribute(warn_unused_result) to all functions. This commit fixes several error handling mistakes.

Added o_stream_nsend*() and related functions to make delayed error handling safer. Once o_stream_nsend*() is called, o_stream_nfinish() must be called before stream is destroyed to finish checking if there were any errors. If something failed and the stream is just wanted to be closed, o_stream_ignore_last_errors() can be called. For streams where errors don't really make any difference (network sockets) you can call o_stream_set_no_error_handling() immediately after creating the stream.

lib-index: Updated dovecot.index file only by recreating it, never write to it directly. This is safer, and nowadays there shouldn't be much of a performance loss with it either, since dovecot.index isn't updated very often. This also allows removing all locking from dovecot.index file, although for now we'll keep it in case old Dovecot versions are simultaneously writing to the index.
