global: start relying on [io]_stream_unref(NULL) being a no-op Cleanup performed with the following semantic patch: @@ expression E; @@ - if (E != NULL) { - i_stream_unref(&E); - } + i_stream_unref(&E); @@ expression E; @@ - if (E != NULL) { - o_stream_unref(&E); - } + o_stream_unref(&E);

dsync: Ignore missing remote mailbox when doing unidirectional sync If there are some folders on remote system that are being ignored by remote brain, do not error out.

Updated copyright notices to include the year 2017.

global: Replaced all instances of memset(p, 0, sizeof(*p)) with the new i_zero() macro. Used the following script: C_FILES=`git ls-files *.c` H_FILES=`git ls-files *.h` for F in "$C_FILES $H_FILES"; do echo "$F" perl -p -i -e 's/safe_memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero_safe(&$1)/g' $F perl -p -i -e 's/safe_memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero_safe($1)/g' $F perl -p -i -e 's/memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero(&$1)/g' $F perl -p -i -e 's/memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero($1)/g' $F done

dsync: When logging "Mailbox changed caused a desync", log also the reason. The reason is usually somewhere in the debug logs, but it's difficult to find from there.

dsync: If state is invalid, exit with code 2 instead of tempfail. We'll have dsync_mailbox_import_*() just return success to everything until _deinit() is called. The _deinit() will return a failure and set "resync needed"-flag, which caller will know how to handle.

dsync: If mailbox importing fails, stop immediately without waiting for exporter to finish.

dsync: Avoid finishing importer successfully on exporter failures. At least dsync_mailbox_import_changes_finish() could have been called when exporter was already failed.

doveadm backup: Detect and handle conflicts earlier. This avoids doing a lot of work, only for the next doveadm backup to just delete the entire mailbox and start from the beginning.

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/'

dsync: Fixed another crash with recent end-of-list changes.

dsync: Earlier end-of-list change broke single-process dsync.

dsync: If mailbox export deinit failed, the failure state may not have reached mailbox importer. The "end of list" was sent to the importer side dsync before export noticed the failure. This could have caused import to complain about missing mails.

dsync: Added assert to make sure end-of-list isn't sent when brain has already failed.

dsync: Use storage's mail_error to choose the doveadm exit code. Instead of always assuming that all errors are EX_TEMPFAIL.

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>

dsync: Removed in/out state from debugging. This was initially added for debugging hangs, but those haven't existed for a long time now. Maybe we should eventually make debug categories configurable, but for now nobody wants to see these messages.

dsync: If we notice that incremental sync won't work, don't continue doing it.

dsync: If incremental dsync finds that its state is stale, retry (later) with full sync. This works only when the master itself notices such changes locally. Remote changes aren't noticed, because the master doesn't send the state to remote dsync and the master is also the one that decides which mailboxes are synced. The fix to this probably means sending the state string to remote dsync and have it check if the state is still valid (= protocol change).

dsync: Include messages_count in the mailbox states. This allows detecting that stateful dsync can't be done when message count is suddenly wrong.

Updated copyright notices to include year 2014.

dsync: Fixed talking to earlier dsync without mailbox attribute support. Most importantly it can now be used as an example how to add more features to dsync.

dsync: -m '' parameter now syncs mailbox list, but no actual mails.

dsync: Avoid a creating a lot of searches for each synced mailbox.

lib-storage: Mailbox attributes can now be accessed via istreams. The idea is to use istreams for larger values.

dsync: Mail requests were lost when attributes were being synced.

dsync: Added support for syncing mailbox attributes.

dsync: If I/O gets stalled, log the state in which it happened.

dsync: Merge last-common-* values from both local and remote when they differ.

dsync: Various importer fixes.

dsync: Don't log a redundant "importing mailbox failed" error.

dsync: Various importer fixes. Handle unexpectedly wrong mailbox state better.

dsync: Automatically figure out which mailboxes can sync with message GUIDs.

dsync: Renamed "guid_requests" to "mail_requests" The mails aren't necessarily requested by their GUID.

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