doveadm director ring status: Add more fields related to connection status

doveadm director: Parse timestamp parameters with str_to_time()

doveadm director: Improve logging unexpected disconnections from director socket Previously it just logged "failed", which wasn't very understandable.

doveadm director kick: Fix -f parameter to work It already worked as --passdb-field, but now it matches the usage string.

doveadm: Actually use resolved IP address(es) in director flush It left the IP variable unitialized which caused host parameter to be left empty causing flush all. Flushing with IP address was not affected.

doveadm director map: Fix checking if host parameter is required

doveadm direcor add: Fix checking number as hostname. 521c0460fe705f32ea6899c8b1f101043fe0898c was completely broken.

doveadm direcor add: Don't accept number as a valid hostname. This is usually a mistake. For example "doveadm director add -t host 100" shouldn't be adding a new IP 100 (0.0.0.100)

doveadm-director: Show tag field from response Fix off-by-one in doveadm director dump

doveadm-director: Include tag in add line

lib: API change - var_expand*() now returns error string. This allows callers to fail properly if the format string is invalid.

doveadm director: Fix memory leaks if hostname lookup fails.

doveadm director dump: Fixed output to include LFs Otherwise all the output will be mixed up in the same line.

doveadm director flush: Added --max-parallel parameter.

doveadm director: Invalid parameters cause doveadm to fail silently. doveadm_cmd_context.cmd doesn't point directly to doveadm_cmd_director.

global: Replaced t_strsplit_tab() calls with t_strsplit_tabescaped() This is useful especially in auth code to support LFs in extra fields. Other pieces of code were also tab-escaping strings, but never unescaping them. Usually it didn't matter, because nobody would use the escaped characters. Still, the code wasn't exactly behaving correctly. One downside to this change is that it's now possible to pass through TABs, CRs and LFs through the various protocols. In theory this shouldn't cause any problems, but combined with other bugs this could trigger some security problems.

doveadm director kick: Added -f <passdb field> parameter. This works for all the user_* passdb fields.

doveadm director kick: Escape username properly. This only mattered if the username contained \001, TAB or LF characters, which isn't normal.

global: Require comparisons to be strict boolean expressions * No implicit integer -> boolean or pointer -> boolean conversions * !expr can be used only if expr is boolean type These were checked with a patched clang. It found various actual bugs, which were fixed by the previous commits.

global: Use hash_table_update() instead of _insert() where necessary.

doveadm-director: Fix commands so that they compile

doveadm-director: Convert to ver2 infra

global: Use [io]_stream_get_error() insted of %m

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/'

doveadm director update: Tag can't be changed - don't allow -t parameter

Remove now-unnecessary direct stdlib.h #includes.

doveadm director update command added. The difference to "doveadm director add" is that if the IP doesn't already exist, it's not added.

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.

director: Added "up" vs "down" states and doveadm director up/down commands. These commands are intended to be used by automated watchdogs that detect if backends are up or down. This way the vhost count doesn't get forgotten after server goes down. It also means that admin can manually take down a server by setting its vhost count to 0 without the watchdog automatically bringing it back up.

doveadm director flush: Unless -F parameter is used, do the flush by moving users. User moving causes the users to be properly kicked out of the old backends before new connections are made to the new backends. This way the user isn't accessed simultaneously by different backends.

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>

director: Added support for backend cluster "tags". This allows using a single director ring for multiple backend clusters. By default everything has an empty tag. A passdb lookup can return "director_tag" field containing the wanted tag name. If there aren't any backend servers with the wanted tag, it's treated the same as if there aren't any backend servers available (= wait for 30 secs for a backend and then return temporary failure). Tags can be added to configuration by adding @tag suffix to IPs/hosts. For example: director_mail_servers = 10.0.0.100-10.0.0.110@name1 10.0.0.120@name2 "doveadm director add" can also add tags either with @tag suffix or with -t parameter. "doveadm director status user@domain" requires giving the user's correct tag with -t parameter or the results won't be correct (empty tag's results are shown). Tags can't currently be changed for an existing host without removing it first.

doveadm director ring status shows now more information

doveadm ring status: Help text was shown for wrong command.

Use the new [io]_stream_create_fd_*autoclose() functions wherever possible.

doveadm director kick command added. The kick gets sent to all the proxies within the director ring.

doveadm director map -u: Don't connect to director socket, it's not needed.

doveadm director map: Added -h and -u parameters to quickly map between username and hash.

doveadm director map: Show also the username hash.

doveadm director move/map: Use director_username_hash setting for calculating hashes.

Replaced all -1U and (unsigned int)-1 with UINT_MAX. It's somewhat clearer this way. Also clang's -fsanitize=integer gives runtime errors about -1U (but not about explicit casts, so no need to change (type)-1 casts).

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