global: Replace ssl_iostream_context_init_client() with ssl_iostream_client_context_cache_get()

global: Rename ssl_iostream_context_deinit() to ssl_iostream_context_unref()

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

lib-imap-client: Support sending IMAP ID command including unique x-session-ext-id

lib-imap-client: Fix hang when imapc_client_get_capabilities() is called without connection

lib-imap-client: Change server IP only on connect() failures Also log an warning-level message about it. This is mainly useful to see that a slow connection could be caused by a connect() timeout. Since more IPs are still available, it's not yet an error.

imapc: Fix infinite reconnection when server keeps sending corrupted state When corrupted state was found, imapc_client_mailbox_reconnect() is called to reconnect. This call skipped the normal "is it safe to reconnect?" checks causing potentially infinite reconnections.

lib-imap-client: Fixed NULL check in assertion to be proper boolean. Found using Clang -Wstrict-bool.

quota: Add imapc backend This allows using imapc storage with imapc quota. The quota acts as read-only, so it's used only when the current quota usage is explicitly asked. The quota can be looked up using either a mailbox name or quota root name. By default INBOX's quota is looked up. If there are multiple quota roots returned for the mailbox, only the first quota root returned by the QUOTAROOT reply is used.

lib-imap-client: Fix imapc_client_get_capabilities() when called without connections

imapc: Make sure client is logged in when checking capabilities Especially with imapc_features=delay-login the capability could have been looked at before the client was even connected.

lib-imap-client: Add unit test Initially this tests some connection and reconnection problems.

lib-imap-client: Make command tag counter externally accessible This allows unit tests to reset it.

lib-imap-client: Call the public login callback exactly once. Previously it was also called only once, as long as there were only a single imap connection. (The current imapc code wouldn't create more than one connection.) It was a bit confusing what the expectation was, so now the callback is never called more than once.

lib-imap-client: imapc_client_deinit() didn't set client=NULL

lib-imap-client: Change connect_retry_interval_secs to _msecs This allows caller to provide better precision.

global: Fix imapc_client_login usage

lib-imap-client: Add login_callback setter This way it can be set before actually calling login which might happen some time later.

lib-imap-client: Only LOGOUT from connected connections

lib-imap-client: Make retry count and interval configurable

lib-imap-client: Add imapc_client_try_stop

imapc: Use LOGOUT to cleanly disconnect from server. This makes it clearer in the remote server's logs whether the disconnection was intentional or not. Use a hardcoded 5 second timeout for LOGOUT. It should be enough time for the server to finish sending the tagged reply.

global: Fix ssl_set usage Remove verify_remote_cert, as it's always TRUE now. Set allow_invalid_cert to TRUE if verification is not required.

lib-imap-client: add callback to notify consumers about state changes Add a callback to notify imapc users about failures. Currently, the only failure defined is "authentication failed".

imapc: Fix re-sending retryable commands after reconnect

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

imapc: Added imapc_max_line_length to limit maximum memory usage. The default is still unlimited, but this should be set to something smaller for untrusted servers.

imapc: Prepare for non-mailbox command retrying: Set reconnect_command_count earlier This probably doesn't fix itself anything yet, but is needed for the following changes.

imapc: Code cleanup - imapc_connection_reconnect() is now always called when reconnect is ok.

imapc: If we get disconnected during SELECT/EXAMINE, retry it once. This seems to be happening especially with dsync migrations from IMAP servers with small timeouts. The initial dsync run opens imapc connection early to do a LIST + SELECT the first mailbox, but then dsync may spend a while creating all the local mailboxes before it continues using the imapc connection.

imapc: Added support for PROXYAUTH command by setting imapc_features = proxyauth This can be useful when talking to Sun/Oracle IMAP server, which wants you to use LOGIN+PROXYAUTH to perform master user logins, instead of supporting the standard SASL PLAIN authentication.

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/'

Replaced unlink() calls with i_unlink*() wherever possible.

lib-imap-client: Allow reconnecting to IMAP server even if there had been no idle moments.

imapc: Don't write SEARCH YOUNGER/OLDER queries if server doesn't support WITHIN extension

lib-imap-client: If we get disconnected and reconnect, log it as warning instead of as error.

imapc: Added throttling settings to imapc_features=throttle:a:b:c This change could be reverted once good settings are found.

imapc: Added imapc_features=search support for sending SEARCH commands. Currently requires the remote server to support ESEARCH (but this would be easy to avoid). This is only minimally tested for now, so bugs may exist (especially related to sub-queries).

imapc: Added imapc_sasl_mechanisms setting The first supported SASL mechanism is used, otherwise the login fails entirely.

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>

Added various asserts to try to silence Coverity false positives.

Updated copyright notices to include year 2014.

imapc: Avoid sending unnecessary IDLEs that are immediately aborted.

Use io_loop_set_current() instead of directly setting it.

imapc: Abort pending commands before any deinitialization to avoid crashes.

lib-imap-client: Added support for UNSELECT capability.

lib-imap-client: Connect and command timeouts are now configurable. Also use the same connect timeout for the DNS lookup's timeout.

Added ssl_client_ca_file to specify the CA certs as a file instead of as a dir. This is required for Redhat-based systems where there isn't a CA directory like in Debian/Ubuntu.

lib-ssl-iostream: API changes to return error strings if init() functions fail. This also fixed a couple of broken error handlings.

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