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

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

lib-storage: Move autoexpunge lock creation to a generic mail_user_lock_file_create()

lib-storage: mailbox_autoexpunge_lock() - Don't hide ENOENT error It means that the user's home directory doesn't exist, which is pretty unexpected. Home directory is supposed to be created when the storage is initialized.

lib-storage: mailbox_autoexpunge_lock() - small cleanup No functional changes - just reorganizing code and adding comments.

lib-storage: Use file_lock_set_*_on_free() for dovecot.autoexpunge.lock

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.

lib-storage: Indicate mail is being autoexpunged This way plugins, such as mail_log, can detect this.

lib-storage: Fix mail_user_autoexpunge() return value to be initialized properly

lib-storage: Change mail_user_autoexpunge() to return number of autoexpunged mails

global: Log internal storage error on failure

global: Log mailbox_list internal errors

global: Add asserts to make static analyzer happier.

lib-storage: Fix autoexpunge locking to actually work correctly. It wasn't actually skipping the autoexpunging if the lock already existed. It autoexpunged anyway.

lib-storage: Lock autoexpunging so only a single process does it. This hopefully helps to avoid duplicates with lazy_expunge plugin.

autoexpunge: Consider last_rename_stamp on expunge When expunging by saved date, see if last_rename_stamp is more recent than saved date, and use that instead. This prevents mails getting deleted on a folder that was just renamed, the user probably expects autoexpunge to consider these emails as fresh.

Updated copyright notices to include the year 2017.

lib-storage: autoexpunge mailboxes with wildcards didn't work with namespace prefix.

lib-storage: Autoexpunging should ignore nonexistent mailboxes. The check was done too late after recent changes.

lib-storage: Add autoexpunge_max_mails configuration to autoexpunge Mails are expunged until mail count is at autoexpunge_max_mails or below. In below example, autoexpunge will expunge 1 mail when message count > 100 and *then* try to expunge mails that are still older than 2 minutes: namespace { .. mailbox Trash { autoexpunge = 2 mins autoexpunge_max_mails = 100 } }

lib-storage: Support autoexpunging from wildcards mailbox names. For example: mailbox Trash { autoexpunge = 30d } mailbox Trash/* { autoexpunge = 30d }

lib-storage: Ignore ACLs when autoexpunging.

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/'

lib-storage: Fixed autoexpunge=yes to work with namespace's root mailbox. namespace { mailbox "" { autoexpunge = .. } }

lib-storage: Fixed autoexpunge for namespaces with non-empty prefix

Compiler warning fix for 32bit systems

Added mailbox { autoexpunge } setting. This can be used to automatically expunge mails from specified mailboxes after they're old enough. The expunges are done when the user is being deinitialized. mailbox_list_index=yes should be enabled to have the best performance with this setting. Example: namespace inbox { mailbox Spam { auto = create special_use = \Junk autoexpunge = 30d } }
