imap: Add client_command_context.event and use it as global event while running

global: Use PRI* macros and %zu instead of casting

lib-storage: Add reason to mailbox_transaction_begin() Remove mailbox_transaction_set_reason().

imap: Add debug logging for [un]hibernation The logs should now clearly say when a client was hibernated and when/why it was was unhibernated.

global: Add mailbox_transaction_set_reason() calls Added to the most important places.

global: Add mailbox_set_reason() calls Added to the most important places.

global: Log internal storage error on failure

imap: If unhibernation fails due to a mailbox error, log the mailbox name.

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

imap: Fix recent flags importing when un-hibernating The initial RECENT counter that was sent didn't include pre-hibernation \Recent flags. \Recent flags were also added for mails that were already expunged, which could have caused recent counter to be wrong later on, and possibly assert-crash with: Panic: file index-status.c: line 130 (index_storage_get_open_status): assertion failed: (status_r->recent <= status_r->messages)

imap: Use correct format specifier for highestmodseq

imap: Add details why unhibernation failed This can help understanding why client failed to unhibernate.

imap: Free box on error Otherwise the box wil leak as it is not assigned anywhere and can cause crash on imap exit due to stats plugin timeout leak.

imap-hibernate: Properly fix hibernation The previous fix did not properly fix hibernation as the clients still dropped out of hibernate. Also the tag used was no longer following. This change will track tag changes and keeps the hibernation process going on until the user enters something else than DONE\r\ntag IDLE\r\n in same packet.

imap: Fixed expunge handling when un-hiberanting Fixes these errors: Failed to import client state: Message count mismatch after handling expunges Message UIDs CRC32 mismatch

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/'

imap: Don't assert-crash if hibernation resumes IDLE, which sends a lot of data to client.

imap: Fix typo in error message.

imap: Fail silently if selected mailbox format doesn't support GUIDs.

imap: Compiler warning fix to imap-hibernate commit

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.
