global: Use unix_socket capability in connection.c This is more reliably way to correctly create input stream with unix socket capability for passing fd's around

imap: Add client_create_finish() to finish namespace creation.

Updated copyright notices to include the year 2018.

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.

imap: Flush response to client before starting possibly long operation Fixes Error: Timeout communicating with /var/run/dovecot/imap-master (version received)

imap: Set client created before initializing namespaces Fixes Panic: file master-service.c: line 819 (master_service_client_connection_destroyed): assertion failed: (service->master_status.available_count < service->total_available_count)

imap: Fix unhibernation after earlier change

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: use o_stream_nsend when not checking failure

imap-hibernate: Preserve mail_user.session_create_time through hibernation

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 assert-crash if un-hibernation failed to initialize user. master_service_client_connection_destroyed() was also being called in imap_master_client_destroy() so it was done twice. Fixes: Panic: file master-service.c: line 775 (master_service_client_connection_destroyed): assertion failed: (service->total_available_count > 0)

imap: When un-hibernating, send notification to imap-hibernate process earlier. The initialization shouldn't take a long time, but there's really no need to keep imap-hibernate itself waiting (and maybe timing out) if it does.

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/'

Fixed compiler warnings in some systems. major() and minor() are unsigned ints nowadays, but in Solaris it's major_t. Cast them explicitly to avoid compiler warnings, and use unsigned longs instead of unsigned ints just in case.

imap-hibernate: Use sockets' st_dev and st_ino to verify that the passed fd is correct.

Changed type of internet port values to in_port_t everywhere. Created special SET_IN_PORT setting type for internet port values. Created net_str2port() for parsing internet port values. Removed several atoi() invocations in the process.

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.
