lib-storage: Add mail_user.event and give parent event in mail_user_alloc*()

lib-storage: mail-user: Added more information about the client connection. Submission service will need it to pass to the backend MTA in XCLIENT and for creating the "Received:" header.

lib-storage: mail-user: Changed mail_user_set_vars() to accept struct mail_user_connection_data, rather than individual fields.

lib-storage: Moved connection information in struct mail_user into separate struct mail_user_connection_data.

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

lib-storage: add a mail user pre-deinit vfunc This allows plugins to perform checks right before the deinit call.

lib-storage: Replace MAIL_STORAGE_SERVICE_FLAG_AUTOEXPUNGE with explicit mail_user_autoexpunge() This allows better control of which users are being autoexpunged. This patch changes behavior at least in two ways now: 1) After shared folder access, the owner user isn't autoexpunged at deinit. Although this is a bit questionable of whether it should be or not. 2) LMTP's quota check at RCPT TO stage doesn't trigger autoexpunging.

lib-storage: Added mail_user_init_ssl_client_settings().

lib-storage: Don't duplicate service user's settings into mail_user The mail_storage_service_user.user_set isn't used afterwards, so it can be directly used to avoid wasting memory.

lib-storage: Add struct mail_user.namespaces_created This makes it easier to determine in mail_namespaces_added hook if the namespaces being added are the initial ones or later ones.

lib-storage: Added mail_user.session_create_time and .session_restored

lib-storage: Added mail_user_set_plugin_getenv_bool()

global: unsigned int:1 -> bool:1 perl -i -pe 's/unsigned int ([^,:;]+):1;/bool $1:1;/' **/*.[ch]

lib-storage: add mail_user_plugin_getenv_bool New API will check boolean-like env setting OR its exsitence. Function returns FALSE when: * Read out a null string, "Or" * String starts with any letter in set {'N', 'n', 'F','f','0'} To keep downward compatibility, For other cases including an empty string, function returns TRUE.

lib-storage: Enable autoexpunge only when MAIL_STORAGE_SERVICE_FLAG_AUTOEXPUNGE is set.

lib-storage: If stats plugin is enabled, set fs_settings.enable_timings=TRUE.

lib-storage: mail_user_init() wasn't always expanding %h correctly to settings. This mainly affected users autocreated for accessing shared mailboxes.

lib-storage: Store pointer to mail_storage_service_user to mail_user if it exists.

lib-storage: Added %{userdb:*} expansion to mail settings.

Removed mountpoint checking and updating code. After a few years it seems like it has just caused more problems than it has actually fixed. The only thing it's been used for is to make sure that Dovecot can't create empty user directories when the user's mail filesystem isn't mounted. But that's supposed to be normally prevented already if the mount root directory permissions are only writable by root. For now the mountpoint listing code and doveadm mount code still exists just in case people have some scripts using those. Those could be removed in v2.3. If we somehow figured out which mountpoints existed (not so easy because they could be only visible in userdb lookups for different users), we could maybe create some kind of a script that checks the permissions at startup. This would work with Linux at least: mkdir test mount / -o bind test ls -ld test/var/mail # assuming /var/mail mountpoint umount test

stats process/plugin redesign to be more modular. The visible functionality doesn't actually change with this patch yet, but it allows other plugins/services to add their own fields to stats process. For example auth process could send auth success/failures or auth cache hits/misses.

lib-storage: Added mail_user_init_fs_settings() Also changed mailbox_list_init_fs() to use it internally.

lib-storage: Added "creator" for mail_user. This allows fixing stats plugin to update stats also for shared mailboxes. That's a bit complicated change though, so I'm not sure how soon it'll happen. But at least this change makes it possible more easily later on. Might have other uses too.

lib-storage: Added mail_user_dup()

lib-storage: Added struct mail_user.session_id

auth, login, mail: Added %{auth_user}, %{auth_username} and %{auth_domain} They expand to the SASL authentication ID. So if master user login is done, it expands to the master user. If username changes during authentication, it expands to the original username. Otherwise %{user} and %{auth_user} are equal.

lib-storage: Added mail_user->admin flag. The previous admin-flag used to mix up "admin user" and "admin tool", while this new purpose only means "admin user".

imapc: Don't log unnecessary errors at deinit about aborted hiearchy separator lookup. The lookup is done asynchronously at startup. It doesn't matter if we never get around to finishing it.

Removed ambiguous mail_user.admin flag. dsync shouldn't sync mailboxes without +r ACL.

lib-storage: Added struct mail_user.nonexistent flag, which is filled by userdb lookup.

lib-storage: Added struct mail_user.nonexistent flag, which is filled by userdb lookup.

lib-storage: Fixes to handling separation of private/shared attributes.

lib-storage: Added mail_user_get_storage_class(), which auto-loads storage plugins. The auto-loading is done only if there's already a stub storage registered.

Backported parts of normalizer_func_t changes from v2.2 tree.

Replaced "decomposed titlecase" conversions with more generic normalizer function. Plugins can now change mail_user.default_normalizer. Specific searches can also use different normalizers by changing mail_search_context.normalizer.

Added support to perform token-based service process authentication. Creates hidden SASL method DOVECOT-TOKEN. This method is not available on the normal auth login socket and thus never presented to clients. Creates new auth socket type 'tokenlogin'. This otherwise normal login socket only offers authentication using the DOVECOT-TOKEN mechanism. Creates new token-login directory in base_dir to separate token logins from normal logins. This directory is otherwise completely identical to the normal login dir, i.e. it contains sockets for the service backends, used to chroot login processes to, etc. Makes default login socket configurable. Performs some minor changes to src/login-common to build very sparse protocols, e.g. avoid the need to implement methods that are not needed.

Array API changed: ARRAY_DEFINE(name, type) -> ARRAY(type) name Easy way to update your existing code: perl -i -pe 's:ARRAY_DEFINE\(([^,]+), *([^)]+)\);:ARRAY($2) $1;:' **/*.[ch]

Adds 'anonymous' field to struct mail_user; derived indirectly from userdb extra fields. Depends: none

Initial implementation of dsync-based replication.

Show SEARCH=FUZZY in IMAP capabilities only when FTS backend actually supports it.

lib-storage: Abort index/control/alt root dir creation if mountpoint isn't mounted.

lib-storage: Handle %{uid} and %{gid} expansion without relying on process's euid/egid.

lib-storage: Added separate %{gid} expansion to mail_user. The default %{gid} probably works also, but it's more reliable to do this explicitly.

lib-storage: Set struct mail_users.autocreated for raw/shared users.

lib-storage: If user->error is set during initialization, fail user creation.

Added mail_temp_dir setting, used by deliver and lmtp for creating temp mail files.

lib-storage: Plugin API changed to run plugin functions in correct order. Previously the hooks were run in correct order, but the functions they overrode were run in reverse order. This caused problems when multiple plugins were used. --HG-- branch : HEAD

lib-storage: mail_user.get_temp_prefix() method added. --HG-- branch : HEAD

lib-storage: If INBOX can't be opened/synced, log an error once. --HG-- branch : HEAD

lib-storage: Added mail_user_is_plugin_loaded(). --HG-- branch : HEAD

lib-storage: Plugin hook API changed to support per-user plugins within a process. --HG-- branch : HEAD

lib-storage: Changed APIs to fix reading settings for multiple users. --HG-- branch : HEAD

Merged single and multi mail_storage_service_*() functions. --HG-- branch : HEAD

mail storages can now be shared between namespaces. --HG-- branch : HEAD

Implemented anvil service, which is used to implement mail_max_userip_connections. --HG-- branch : HEAD

Added lib-master and mail-storage-service code that makes it easier to build new Dovecot binaries. Currently only the standalone applications (e.g. deliver) uses this. --HG-- branch : HEAD

Added mail_user_get_temp_prefix() and mail_storage_get_temp_prefix(). --HG-- branch : HEAD

Fixed plugins to work with config rewrite. --HG-- branch : HEAD

Initial commit for config rewrite. --HG-- branch : HEAD

hook_mail_namespaces_created() wasn't always called with all namespaces as parameter. --HG-- branch : HEAD

Quota works now properly with shared mailboxes. --HG-- branch : HEAD

mail_user_*() now handles home directory lookups when necessary. Namespace owner is now a pointer to struct mail_user rather than a string. --HG-- branch : HEAD

Don't drop useless namespaces automatically while creating a new one. It may free namespaces that are still being used elsewhere. Rather do it explicitly at the beginning of each mailbox sync. --HG-- branch : HEAD

Added initial support for shared mailboxes. Listing isn't supported yet. Each user gets their own hidden namespace created automatically when they're accessed the first time. --HG-- branch : HEAD

Created mail_user_[try_]home_expand(). Used them for expanding mail directories. --HG-- branch : HEAD

Forgot to add mail-user.* files in previous struct mail_user commit. --HG-- branch : HEAD
