Highlights since 5.4.x ---------------------- • MC implements features from telepathy-spec 0.20, including: · channels can be dispatched before a connection is CONNECTED, which is required for telepathy-gabble ≥ 0.9.17 · the Account.ConnectionError property indicating the last error · the Account.ChangingPresence property indicating that presence changes are in progress · the Account.Service property indicating where an account is stored · ChannelDispatchOperation.HandleWithTime to set focus-stealing-prevention timestamps • libmission-control-plugins provides a more stable plugin API for MC. Plugins written with this library can: · observe, delay and influence channel dispatching, much like Observers · observe, delay and/or reject channel requests · store accounts elsewhere • Bugfixes include: · tries harder to invoke the same handler for an already-handled channel · calls ended locally with reason No_Answer are treated as missed · fewer writes to gnome-keyring when committing changes · in-band XMPP account creation works better Fixes since 5.5.4 ----------------- • Fix various build warnings in the tests (Vincent Untz, smcv) • Fix a build warning when keyring support is disabled (fledermaus) • Install a missing header file (fledermaus) telepathy-mission-control 5.5.4 (2010-09-14) ============================================ The "salamander king" release. Enhancements: • fd.o #26699: add support for plugins that delay requests while deciding whether to allow them or not (smcv) • Restructure channel-requesting code (smcv) • Delete the old examples, which are no longer exemplary; use telepathy-glib or telepathy-qt4 instead of libmcclient (smcv) • fd.o #29812: add a trial implementation of the MinimumPresence (draft 2) API (ptlo) • fd.o #30000: add a trial implementation of SucceededWithChannel and {Create,Ensure}ChannelWithHints (cassidy, smcv) Fixes: • fd.o #28915: fix a regression in which parameters that are unset aren't necessarily saved to the configuration file (fledermaus) • Signal remote avatar deletion, for instance by another XMPP resource, in the same way as a remote avatar change (fledermaus) • Cancel the "probation" timer when the connection is released, avoiding a possible crash (fledermaus) • Ignore any partial pre-existing accounts that have no manager or protocol listed, and if a storage plugin creates a totally unusable account, ignore it (fledermaus) • Don't crash if Proceed() is called twice (smcv) • Various fixes for the Maemo SSO plugin (fledermaus, eeejay) • Fix linking with recent ld versions (smcv) telepathy-mission-control 5.5.3 (2010-07-22) ============================================ Dependencies: * telepathy-glib 0.11.9 is now required Enhancements: * Added support for the new Account.Service property in the MC core code and the SSO plugin (fledermaus) * Added support for the Service property to mc-tool (wjt) * Made account storage plugins able to notify MC that a single account has changed externally (fledermaus) * Added support for plugins that check D-Bus calls' callers against an ACL (fledermaus) Fixes: * Treat calls ended locally with No_Answer as missed (wjt) * fd.o #24645: when an existing channel is returned by EnsureChannel and its handler has more than one Handler bus name/object path sharing a unique name, MC now tries harder to invoke the same one as before (smcv) * Disable accounts when they're deleted by an account storage plugin (fledermaus) * Attempt re-connection of failed connections less rapidly (wjt) telepathy-mission-control 5.5.2 (2010-06-16) ============================================ The "513M accounts.cfg, which seems terribly wrong" release. Dependencies: * telepathy-glib 0.11.7 is now required Enhancements: * fd.o #28428: implement the new ConnectionError property from telepathy-spec 0.19.7, and if an Account's Connection-related property changes, put all the related properties in the change notification signal to make it easier to interpret (smcv) Fixes: * fd.o #28557: write account parameters to accounts.cfg correctly, rather than repeatedly escaping backslash, newline, tab etc., which resulted in doubling the number of backslashes with every write. If this has made your accounts.cfg so large that deleting accounts via Empathy is difficult, see https://bugs.freedesktop.org/show_bug.cgi?id=28557 for a workaround. (smcv) * fd.o #28390: drastically reduce writes to gnome-keyring when committing changes to accounts (wjt, smcv) * fd.o #28118: clear the 'register' parameter when an account connects successfully, fixing in-band XMPP account creation (smcv) This version includes the stable-branch bug fixes from 5.4.3. telepathy-mission-control 5.5.1 (2010-06-03) ============================================ The "red head headache" release.

The API mostly mirrors the Telepathy D-Bus API. (smcv/fledermaus) * accounts now support the ChangingPresence property from telepathy-spec 0.19.6 (andrunko) * channel dispatch operations now support the HandleWithTime method from telepathy-spec 0.19.6 (ptlo) * channels can be dispatched before a connection goes CONNECTED, which is needed for SASL authentication channels (eeejay) * compiler warnings are correctly enabled (smcv) Removals: * libmcclient is no longer installed as a separate library unless the old plugin interface is enabled * fd.o #26634: the obsolete utility mc-account-convert, for migration from Mission Control 4, has been removed Fixes: * don't time out channel requests until many hours have passed (sjoerd) * instead of emitting AccountPropertyChanged signals in time-based batches with a small delay, change signals are now grouped into atomic changes (smcv) * fd.o #24876: no longer reimplements a GLib 2.22 method (smcv) * fd.o #25122, Debian #556488: link mc-wait-for-name to GLib correctly (jonny) * fd.o#26597: use TpDebugSender to send debug messages over D-Bus (eeejay) * don't crash mc-tool when the account name is invalid (wjt) * fd.o #27015: remove a misleading reference to GConf (tomeu) * fd.o #27129: update and simplify test/twisted/README (tomeu/smcv) * fd.o #25684: fix detection of accounts that already exist (Jani Monoses/smcv) * in libmcclient, don't crash on malformed profiles where a group is missing (smcv) Maemo-specific enhancements: * added a libaccounts-glib-based account storage backend (fledermaus) telepathy-mission-control 5.4.2 (2010-05-26) ============================================ The "everyone loves magical re-entrancy" release.

Fixes: * set 0 as UserActionTime when HandleWith is used (cassidy) * make tests pass with more recent telepathy-glib, which can call GetInterfaces twice (cassidy) * don't cache whether we have the Requests interface, which caused one of the tests to regress (smcv) telepathy-mission-control 5.4.0 (2010-04-15) ============================================ The "coffee made without human interaction" release. Enhancements: * fd.o #27309: implement the Observer.Recover flag from the forthcoming telepathy-spec 0.19.4, which lets activatable observers recover (in a best-effort way) after crashing, and lets non-activatable observers catch up on active channels (again in a best-effort way) (ptlo) Fixes: * fd.o #24875: avoid a dependency on GLib >= 2.22 which was accidentally introduced in 5.3.2 (smcv) * Avoid a dependency on dbus-glib 0.80 (Danni) * fd.o #25122, Debian #556488: link mc-wait-for-name to GLib properly (Jonny) * mc-tool: don't crash on invalid account names (wjt) * Only time out channel requests after 5 hours (Sjoerd) * Remove a misleading reference to GConf (Tomeu) * fd.o #27021: fix error propagation when creating accounts with invalid properties/parameters (Tomeu) * Release startup locks even for incomplete accounts, avoiding failure to start (fledermaus) telepathy-mission-control 5.3.2 (2009-11-02) ============================================ The "Flight Of The Living Dead" release. Enhancements: * mc-wait-for-name: give up after 5 minutes and exit EX_TEMPFAIL. Also exit with EX_UNAVAILABLE (instead of 1) if the session bus doesn't work, EX_USAGE (instead of 1) on wrong arguments, and EX_USAGE (instead of g_critical() and never terminating) if the requested bus name is not valid (smcv) * fd.o #23651: strongly prefer the PreferredHandler for a channel request, and try dispatching to it even if its HandlerChannelFilters do not indicate that it could handle the channel, since this is very useful for clients like nautilus-sendto (smcv) * fd.o#24120: refactor McdDispatcher quite extensively: + always have a McdDispatchOperation for each McdDispatcherContext, even if no approval is needed + migrate the dispatching state machine into the dispatch operation + move client logic into McdClientProxy, removing the McdClient struct + migrate Client discovery and the client registry into a new class McdClientRegistry + remove many unused signals + use McdDispatcherContext for the plugin API and nothing else (smcv) * McdHandlerMap: operate in terms of TpChannel, not McdChannel, to make the code less tightly coupled; watch for channels closing and client crashing internally, rather than relying on other modules (smcv) * Run the regression tests with GLib and GObject warnings set to fatal (smcv) Fixes: * fd.o #23687: if all Handlers with BypassApproval fail, notify approvers and wait for approval before trying other Handlers (smcv) * fd.o #24474: notify Observers about channels that were requested without going via MC, e.g. by Empathy 2.28.x (smcv) * fd.o #21003: delay the return from HandleWith until HandleChannels has succeeded or failed, and pass on errors; do not consider HandleWith(H) to be general approval for the channel to be handled with handlers other than H (smcv) * fd.o #24637: don't emit Finished until the channel dispatch operation has really finished (smcv) * Fix a possible use-after-free when noting that a client has gone away (smcv) * Avoid re-dispatching a re-requested channel to a different handler (smcv) * When calling HandleChannels, use the most recent user-action time from among all requests that led to this channel, and all HandleWith() calls for this channel dispatch operation (smcv) * Don't call ReloadConfig() on the dbus-daemon (reopening fd.o#23921), to avoid triggering fd.o#24350 in dbus-daemon and causing service-activations to fail (sjoerd) * mc_account_conditions_call_when_ready: explain why it's OK to ignore the result of mc_iface_call_when_ready_int, which was a Coverity false-positive (smcv) * Consider calls to be potentially-missed if they terminate for reason ERROR, even if we're the actor, because that's what happens in Gabble >= 0.8.4 if the streaming implementation (i.e. telepathy-farsight) discovers that none of the candidates work and calls Error() (smcv) * Fix a race condition in the test account-manager/make-valid.py, which would sometimes incorrectly make it fail (smcv) * Add a regression test for dispatching and requests being delayed while waiting for a plugin to make an asynchronous request for permission (smcv) * Don't leak check_parameters_get_param_cb closure on error (smcv) * In libmcclient, invoke callbacks for GetAll() in the right order (mardy) All fixes from stable release 5.2.6 have been incorporated in this release. telepathy-mission-control 5.3.1 (2009-09-18) ============================================ The "only available in Belgium" release. Dependencies: * Python >= 2.5 is now required for compilation * telepathy-glib >= 0.7.37 is now required Enhancements: * Automatically migrate passwords and other secrets from accounts.cfg into the GNOME keyring (if enabled and available) on MC startup (jonnylamb) Fixes: * Deal with the user's alias in a race-free way by calling GetAliases as well as binding to the AliasesChanged signal (smcv/mardy) * Fix some race conditions in the regression tests (smcv) * Fix mcd_dispatcher_get_channel_type_usage sometimes counting aborted channels, by introducing MCD_CHANNEL_STATUS_ABORTED (mardy) * If we see too many transitions from CONNECTED to DISCONNECTED state (i.e. we get kicked off by the server more than 3 times in 2 minutes), stop reconnecting; also, don't reset the exponential backoff until we've been connected for 2 minutes. This avoids reconnecting in a tight loop if the server lets us connect, then immediately drops our connection. (smcv) * Fix some minor memory leaks (smcv) All fixes from stable releases 5.2.4 and 5.2.5 have been incorporated in this release. telepathy-mission-control 5.3.0 (2009-09-14) ============================================ The "displatcher" release, starting a new development branch. Dependencies: * The GNOME Keyring library is a new optional dependency (only if configured with --enable-gnome-keyring=yes or --enable-gnome-keyring=auto). If it is enabled, having the library at runtime is required, but having the daemon itself is optional - the current plain-text storage will be used for passwords if the keyring daemon is not available. Enhancements: * fd.o#20903: support the final version of ContactCapabilities, from telepathy-spec 0.17.28 (smcv) * fd.o#22231: add optional gnome-keyring integration. This is off by default, but distributions should consider configuring MC with --enable-gnome-keyring to get this functionality. (jonnylamb/smcv) * mc-tool: show full Presence information (sjoerd) * Use the "mcd" G_LOG_DOMAIN (smcv) * fd.o#23501: support TpDebugSender (smcv) * Stop #define'ing g_object_ref, g_object_unref (smcv) * fd.o#22705: support MC_DEBUG=all (smcv) Fixes: * Escape "-" in protocol names in Account names, as required by the Telepathy spec (sjoerd) * fd.o #23818: if HandleChannels fails, try all Handlers in sequence before giving up (smcv) * Refactor client locking in McdDispatcher to be more obviously correct (smcv) * Don't define macros used in glibc feature-test internals, possibly fixing failure to build from source on Debian GNU/kFreeBSD (smcv) * Fix a reference leak when shooting down an unwanted Connection (wjt/smcv) * fd.o#23921: force dbus-daemon to re-detect .service files on MC startup, as a partial workaround for D-Bus bug fd.o#23925 (George Goldberg) * fd.o#23935: call AddRequest if appropriate even on clients that match only channels with Requested=true, and use requested channels' complete properties in preference to the properties that were requested (smcv) * Make signed values in .client files work instead of g_critical'ing (smcv) * This release also includes all bugfixes from stable-branch versions up to and including 5.2.3. telepathy-mission-control 5.2.3 (2009-09-10) ============================================ The "Morden, via Bank" release. Fixes: * fd.o #23807: even if someone without gconf headers makes the tarball, ship the necessary files so people with gconf headers can compile it (smcv) * Resync what's in git with what's in tarball releases: remove some unused source files from git, add more support files to tarballs, and don't distribute any generated source in tarballs (smcv) telepathy-mission-control 5.2.2 (2009-09-07) ============================================ The "St. Pancreas" release. Enhancements: * Better debug output under various circumstances, including outputting the version number on startup (smcv) * Add the concept of always-on accounts, which can't be disabled or otherwise put offline (smcv) * Try to set initial presence before calling Connect (smcv) Fixes: * fd.o #23778: make sure account details (including passwords) are stored in directories readable only by the user. Distributions wanting this fix without any other changes should cherry-pick git commits 16c55625, 2a42ac03, c16f40ec and 3558c3b2 (smcv) * Replace deprecated g_strcasecmp with g_ascii_strcasecmp (Jonh Wendell) * Don't close old-style Tubes channels if they can't be dispatched, since that closes the new-style StreamTube/DBusTube channels that everyone should be using, as a side-effect (smcv) telepathy-mission-control 5.2.1 (2009-08-26) ============================================ The "secret cake" release. Enhancements: * Add change notification in the Compat interface (mardy) * Make the low-memory check overridable by subclasses (smcv) * Complete online requests with error on DISCONNECTED -> DISCONNECTED transition (i.e. cancellation) (mardy) * Set the initial connection status reason to Requested, since None_Specified usually means "generic error" (mardy) Fixes: * fd.o #23509: wait for observers and approvers to finish initial processing before letting Claim() finish (smcv) * Don't allow transition from one transport to another (smcv) * If a transport plugin stops a connection before RequestConnection has even returned, remember that, and disconnect that Connection later when it does turn up (smcv) telepathy-mission-control 5.2.0 (2009-07-30) ============================================ The "too many timeouts, reducing the advertised EDNS UDP packet size to 512 octets" release. This is the first release of a new 5.2.x stable branch, available in git as the 'telepathy-mission-control-5.2' branch. Feature development will continue in the 5.3.x series. Enhancements: * Update ContactCapabilities draft to the version in telepathy-spec 0.17.26 (smcv) * Add regression tests for Capabilities, and for ContactCapabilities draft 1 (smcv) Fixes: * McdConnection: fix a rare crash if no fallbacks for a presence are supported (smcv) * libmcclient: avoid invoking callback twice if the object is already ready (mardy) telepathy-mission-control 5.1.4 (2009-07-09) ============================================ The "I only came here seeking peas" release. Dependencies: * fd.o #22332: GConf is no longer required (if it is not available, then the MC 4 to MC 5 migration tool, mc-account-convert, will not be built) Enhancements: * fd.o #21378: support connection manager parameters whose value is a single byte (smcv) * Add simple man pages for the daemon and utilities (smcv) Fixes: * fd.o #22670: don't assume a client has crashed just because it has lost a well-known name (smcv) * Don't use the AutomaticPresence status from account configuration unless the presence type is an online presence (mardy) * fd.o #22585: remove symbols from libmissioncontrol-server that collide with symbols in libmcclient, allowing the telepathy-mission-control daemon to be statically linked on platforms that don't want to support plugins (smcv) telepathy-mission-control 5.1.3 (2009-07-01) ============================================ The "wilting" release. Enhancements: * Improve test coverage, including EnsureChannel (smcv) * In tests, add the ability to test an installed MC binary (installcheck) (smcv) Fixes: * Make sure that ChannelDispatchOperations emit Finished before they are unreffed for the last time (smcv) * Stop mcd_mission_abort() from implicitly closing channels, meaning that when Close() has an extra protocol-level meaning (for instance, when using an IRC proxy), we don't respond to connection loss by departing from all channels. Instead, explicitly close channels whenever desired (smcv) * Add API for plugins to destroy channels, close channels with a reason, or "forget" (do not dispatch) channels (smcv) * In situations where channels can't be handled, use Destroy() to terminate them, if available (smcv) * In wait-for-name, initialize error properly if we can't connect to D-Bus (smcv) * In tests, restructure `make check-torture` so it doesn't exceed command-line length limits (smcv) * Use g_file_set_contents to overwrite files (mardy) telepathy-mission-control 5.1.2 (2009-06-26) ============================================ The "don't cross the stream engines" release. Dependencies: * telepathy-glib >= 0.7.32 (or 0.7.33 if you want to run the regression tests) Enhancements: * Stop generating duplicate bindings in the daemon for interfaces that are now available in telepathy-glib 0.7.32 Fixes: * Fix a subtle use-after-free that can crash MC if more than 4 distinct properties change in a 10ms interval (!) * Make various fixes to putting accounts online: - ConnectAutomatically takes effect immediately - Fix a race between loading accounts and requesting channels - Never consider accounts to be Valid until they've loaded, meaning that we never try to put an account online before we've loaded its parameters (!) - Don't connect (automatically or by request) unless the account is Valid - Don't connect in order to satisfy a channel request unless the account is both Valid and Enabled - Allow setting RequestedPresence on disabled accounts, fixing creation of accounts that already have a RequestedPresence - Improve regression test coverage considerably - If an account's parameters change and it becomes Valid, consider putting it online - If an account becomes enabled after an online presence was requested, try to put it online * Change the default RequestedPresence on startup from UNSET to OFFLINE * Simplify API for low memory indication * Delete some unnecessary code from McdMaster, and simplify some redundant code * Forbid setting AutomaticPresence to a non-online status * Forbid setting RequestedPresence to a status that can't be set on yourself * Fix a memory leak and some races in the regression tests * Turn the daemon into a convenience library so one of the tests can link it statically even if it's eventually going to be a shared library, fixing make check with --enable-plugins telepathy-mission-control 5.1.1 (2009-06-16) ============================================ The "Beautiful And Damned" release. Fixes: * fd.o #22169: allowed PreferredHandler to be empty when requesting a channel (smcv) * Updated code generation from telepathy-glib and followed the recommendations of telepathy-glib 0.7.6's NEWS, fixing some possible assertion failures (smcv) * Ensured that AccountValidityChanged will be emitted if an account is added in an already-valid state (smcv) * fd.o #21377: added support for 64-bit integers, doubles and object paths as CM parameters, did some work towards supporting bytes as CM parameters, and fixed serialization of large 32-bit unsigned integers and deserialization of integers of large magnitude (smcv) * fd.o #21299: prevented automatic reconnection after Name_In_Use error (smcv) * fd.o #22201: avoided rewriting accounts.cfg if nothing changed (smcv) * Ensured that the transport was reset when a Connection disconnected (mardy) telepathy-mission-control 5.1.0 (2009-06-05) ============================================ The "beta 75 would have been silly" release. After months of development, this is the first numbered release of Mission Control 5. We jumped straight to 5.1 in order to use the Linux-style odd/even versioning seen in the other Telepathy components, so the 5.1.x development branch will lead to the 5.2.x stable branch. Changes since Mission Control 4 are too numerous to list here, but here are the major architectural changes. The proprietary MissionControl API no longer exists; the daemon is a telepathy-spec-compliant AccountManager, and also a telepathy-spec-compliant ChannelDispatcher. Consequences of this include: * Clients are no longer expected to implement the ChannelHandler interface. Instead, they may implement the Observer, Approver and/or Handler interfaces specified in telepathy-spec. * The design of channel dispatching copes better with having multiple user interface components installed. * Accounts' presence, avatar and nickname are now independent (stored per-account), allowing for more precise control by UIs. * Accounts no longer have to belong to a "profile", although they still can (albeit only by using a non-standard extension). Accounts are now stored in a flat file, rather than by abusing GConf. The included mc-account-convert tool might be able to convert MC 4 accounts to the MC 5 format, if you're lucky. libmissioncontrol-server has changed its API and ABI considerably, and is not yet considered stable in its new form either. It is no longer installed by default (in a normal configuration it'll just be compiled into the daemon). libmissioncontrol (based on libtelepathy and also known as libmissioncontrol-client) no longer exists, and has been replaced by libmcclient (based on telepathy-glib). Mission Control 5 is not a drop-in replacement for Mission Control 4, and cannot be used by Mission-Control-4-based applications like Empathy 2.26 and the Maemo 4 platform. However, both versions can be installed independently in the same directory prefix, to facilitate porting from one to the other. Known regressions since Mission Control 4: * There is no gnome-keyring integration yet. * The client and server library APIs are not considered to be stable yet.
