SyncEvolution 1.2.2 -> 188.8.131.52, 22.06.2012
First pre-release of SyncEvolution 1.3. Contains bug fixes that were
not backported to 1.2.x, so upgrading is recommended. For example,
SyncEvolution 1.3 is required for Evolution 3.4, otherwise photos are
not exported properly. Further workarounds for recent changes in
Google CalDAV were added.
Major new features are KDE/Akonadi support in the syncevolution.org
binaries and ActiveSync support (only in the source code). The D-Bus
server and local sync were rewritten considerably, to make the code
cleaner and more robust. The CalDAV backend now also supports tasks
* phone sync: delete<->delete conflict + phone calendar+todo sync (BMC #23744)
When deleting an item on phone and locally, the next sync failed with
ERROR messages about "object not found". This has several reasons:
- libsynthesis super data store attempts to read items
which may or may not exist (triggers ERROR message)
- it checks for 404 but Evolution backends only return a generic
database error (causes sync to fail)
* phone sync: get phone vendor and model from Device ID profile (BMC #736)
In the past we have relied on the user-modifiable device name to be
the fingerprint for matching a phone to a template which is unreliable.
This release changes this in the cases where the phone supports the
Device ID profile (DIP). If support for DIP is detected, then we
extract the vendor and product ids and attempt to associate them
with a product and vendor name by using a newly added lookup table.
This lookup table has to be maintained manually and depends on
contributions by users to cover more devices. See
* vCalendar 1.0: fixed recurring all-day event support
vCalendar 1.0 cannot represent all-day events. The workarounds for
mapping iCalendar 2.0 all-day events into vCalendar 1.0 was
incomplete, leading to effects like shifting EXDATEs and end
* GTK-UI: accept service config with a username again (BMC#23106)
Suppressing configs with empty username had undesired side effects:
modifying configs for direct syncing with a device incorrectly
triggered the same error message, without any means of entering
a username. The faulty check was removed without replacement.
* GTK-UI: added GTK 3 version of UI
When GTK 3 is found during compilation, a GTK 3 version of the
UI is built. The source code of both is different to avoid
excessive use of ifdefs. At the moment, both versions offer
the same features. In the long run, the GTK 3 version will
replace the GTK 2 version.
* command line: added refresh/one-way-from-local/remote (BMC #23537)
The -from-client/server sync modes are confusing because the direction
of the data exchange depends on which side acts as SyncML server or
This release introduces new modes which use -from-local/remote
instead. The statistics and messages also use these variants
now. The old modes are still understood, but are declared as "not
recommended" in the documentation.
* command line: config and source names are optional (BMC #23783)
The need to add "foo" and "bar" pseudo config and source names to
command line even when all parameters for the operation where
explicitly specified on the command line was confusing.
Now it is possible to invoke item operations without the config and
source name. Names which refer to non-existent configs are still
accepted, as in previous releases. Typos are handled better by
producing a detailed error report which includes (as applicable):
- config doesn't exist
- source doesn't exist or not selected
- backend property not set
Because luids used to be positional arguments after <config> and
<source>, a new --luids keyword is necessary to indicate that the
ensuing parameters are luids and not <config> and <source>.
* command line: introduced --print-databases, supported for CalDAV/CardDAV
Listing databases is now a dedicated operation, instead of being done
whenever syncevolution was invoked without parameters.
- can be combined with property assignments for backends
which do not work without that additional information, for example
syncevolution --print-databases \
- can be done for configured sources
* command line: use both stdout and stderr
Traditionally, the "syncevolution" command line tool mixed its
INFO/ERROR/DEBUG messages into the normal stdout. This has the major
drawback that error messages get lost during operations like
syncevolution --export - @default addressbook | grep "John Doe"
Now anything which not the expected result of the operation is
always sent to stderr. Obviously this includes ERROR messages. INFO
and DEBUG are harder to decide. Because they usually convey meta
information about the running operation, they are also sent to
stderr. The output of running a sync goes to both stdout (summary)
and stderr (progress).
* command line: allow setting empty properties
Due to the way how properties were handled internally, it wasn't
possible to explicitly set a property to its default value. Instead
the property was unset. For example, explicitly setting database= was
This is necessary for client-test and ActiveSync, because client-test
needs to know that the testing is expected to run with the default
databases (something which normally is avoided by overwriting empty
Now the "is set" state is tracked explicitly in the config storage and
command line property APIs. Unsetting a property via the command line
could be implemented with an explicit command line option, but is not
supported at the moment.
* command line + local sync: fixed erroneous "Comparison impossible" output.
"Comparison impossible" was incorrectly printed after a successful
comparison on the target side of local sync.
* synccompare: shorter data dump of PHOTO
A full comparison of the base64 PHOTO data can be very long.
Now some key characteristics of the PHOTO data (number of
characters in base64 encoding, number of bytes in decoded
data, md5sum of decoded data) are printed instead.
That way, unintended changes of the data (different encoding,
different content) should still be found while testing and
added/removed photos are nicely visible in synccompare diffs.
* synccompare: fixed output for byte-identical duplicates
If database dumps contained byte-identical duplicates, they
were treated as a single item on the left side of a comparison.
This caused erroneous "added" entries on the right side.
* secure password storage: usage of GNOME Keyring vs. KDE KWallet configurable
Automatically detecting KDE users is not possible at the
moment. Instead KDE users have to manually set the new "keyring"
global config property to "KDE" (case insensitive) if the
SyncEvolution installation supports both, because GNOME Keyring is the
default to avoid surprises for traditional users. If only KWallet
support is enabled, then this is not necessary.
"GNOME" and "true/false/1/0/yes/no" can also be set. This has the
advantage that keyring usage can be enabled permanently for the
command line in --daemon=no mode; normally keyrings are not used in
that mode because accessing them can bring up UI dialogs.
It also becomes possible to disable keyring usage in syncevo-dbus-server,
something which couldn't be done before.
The --keyring command line option is still supported, as an alias for
"[--sync-property] keyring=<value>". The default value for --keyring
is true, to match the traditional behavior. In contrast to other sync
properties, setting "keyring" does not require an explicit --run
parameter. Again this is done to mirror traditional usage.
* Evolution: always create databases (PTCOM-113)
Always try to create address book or calendar database, because even
if there is a source there's no guarantee that the actual database
was created already; the original logic for only setting this when
explicitly requesting a new database therefore failed in some cases.
This problem affected users who had never created anything locally
and wanted to use SyncEvolution to migrate their data. Now that
works without having to create dummy entries first.
* Evolution contacts: changed default sync format to vCard 3.0
vCard 3.0 is the better default because it has saner encoding
rules and defines more properties, thus avoiding the need for
non-standard extensions. However, Mobical has problems with
the new default. See upgrade instructions below.
* D-Bus server: made notification verbosity configurable with "notifyLevel"
The new "notifyLevel" per-peer configuration option allows users to
control how many desktop notifications the D-Bus server produces while
executing an automatic sync:
0 - suppress all notifications
1 - show only errors
2 - show information about changes and errors (in practice currently the same as level
3 - show all notifications, including starting a sync (default)
* CalDAV: updated Google workarounds
Google started sending empty items (VCALENDAR with no VEVENT inside)
which cannot be removed. SyncEvolution 1.3 ignores such items.
The workaround for a 404 from Google Calendar for a GET (sending a
REPORT request matching the item's UID) was broken: first, processing
the result ended up calling the unset responseEnd boost function
pointer, which caused the request to fail. Second, getting multiple
items wasn't handled (data from all items concatenated together was
That can happen in the somewhat unlike case that some items have a UID
which is a complete superset of the requested UID - not realistic in
real life, but happens during testing.
* WebDAV: bridge with SyncML
Now a peer accessed via SyncML can read/write data stored in a
CalDAV/CardDAV server directly. This can be used to connect a device
which only supports SyncML to a CalDAV/CardDAV server, or sync data
between a SyncML server and a CalDAV/CardDAV server. See "CalDAV and
CardDAV" in the README for details.
* WebDAV: improved --configure
Added INFO output about checking sources. This helps with WebDAV when
the server cannot be contacted (dead, misconfigured) because otherwise
there would be no indication at all why the --configure operation
seems to hang.
Here is some example output, including aborting:
$ syncevolution --configure --template webdav \
username=foo password=bar retryDuration=2s \
[INFO] creating configuration target-config@webdav-temp
[INFO] addressbook: looking for databases...
[INFO] addressbook: no database to synchronize
[INFO] calendar: looking for databases...
[INFO] calendar: no database to synchronize
[INFO] memo: looking for databases...
[INFO] memo: no database to synchronize
[INFO] todo: looking for databases...
[INFO] todo: no database to synchronize
It timed out fairly quickly here because of the retryDuration=2s. That
also gets placed in the resulting config, which is probably not desired.
Aborting the operation is now supported:
$ syncevolution --configure \
--template webdav \
username=foo password=bar \
[INFO] creating configuration target-config@webdav-temp
[INFO] addressbook: looking for databases...
^C[INFO] Asking to suspend...
[INFO] Press CTRL-C again quickly (within 2s) to stop immediately (can cause problems in
^C[INFO] Aborting immediately ...
[ERROR] error code from SyncEvolution aborted on behalf of user (local, status 20017):
aborting as requested by u
It would be good to make the CTRL-C handling code aware that it can
abort immediately instead of doing the intermediate "asking to suspend"
step, which only makes sense for sync sessions.
* WebDAV: support tasks and memos (BMC #24893)
The new backend property values "CalDAVTodo" and "CalDAVJournal"
select tasks resp. memos stored in a CalDAV collection. "CalDAV"
continues to select events.
Events, tasks and journals can be mixed in the same resource (=
URL). However, this is less efficient than storing them separately.
A good CalDAV server allows filtering items by type, and SyncEvolution
uses that. However, it was found that Radicale 0.7 ignores this
filtering, which could have led to data loss (SyncEvolution asks for
all VTODOs in preparation for a "delete all items" operation in a
"CalDAVTodo" source, gets also VJOURNALs, then deletes them).
Therefore SyncEvolution plays it safe and downloads the VTODO and
VJOURNAL data to double-check that it is working on the right items.
This causes additional traffic for well-behaving servers; currently
it cannot be turned off.
Tasks are exchanged as vCalendar 1.0 or iCalendar 2.0 VJOURNAL.
Memos are exchanged as VTODO or plain text. The logic for storing
incoming plain text is slightly different compared to the way how
the EDS memo backend did it: instead of copying the first line
from the text into the summary, it is now moved. In other words,
the first line gets stripped. The change is primarily technically
motivated; both approaches have pros and cons.
* WebDAV: improved Radicale support
Radicale > 0.7 will return status 200 for delete requests;
is now treated like 204 by SyncEvolution. 412 'Preconditiona Failed'
when asking to delete an already removed item is treated like
the more common 404 'not found'. Same with 410 'gone' instead
of 404 when trying to read a non-existent item.
* file backend: more flexible sync support for memos
The databaseFormat=text/calendar for memos did not support
synchronizing as plain text. When using the new
databaseFormat=text/calendar+plain, vCalendar/iCalendar/plain text
are all valid sync formats; the storage is iCalendar 2.0
VJOURNAL in all cases.
* WebDAV: avoid potential crash during database detection
When a server responds to a PROPFIND for a path with results for some
other path, then SyncEvolution crashed during the search for the
default calendar or address book because of a bug in the code which
was meant to handle that kind of response. Apparently Yahoo Calendar
did that. Now seen again in combination with Radicale 0.6.4.
In general, the code was made more robust to cope with bugs in
Radicale 0.6.4. Later Radicale versions fixed these issues and also
worked with SyncEvolution 1.2.2 without client-side workarounds.
* WebDAV: better path normalization
"syncURL" and "database" properties had to end in a trailing slash,
otherwise items were not found (404 errors). Now the necessary slash
is added automatically.
* Funambol: avoid slow syncs in refresh from server
libsynthesis has traditionally implemented "refresh-from-server" as
"delete local data" plus "slow" sync. This is more compatible,
some servers (like Google) do not support "refresh-from-server".
But it has the downside that the server cannot know that the client
won't send any data, and Funambol's OneMedia now only allows one slow
sync before blocking the next one for a certain period of time. This is
done to prevent excessive resource usage by badly behaving clients.
To accomodate both kinds of servers, the new "enableRefreshSync"
sync property can be set set to explicitly allow the usage of
the "refresh-from-server" sync mode. It's off by default. The Funambol
template has it turned on, existing configs must be updated manually
(see upgrading comments below).
* Curl transport: support SSLServerCertificates=<path>
When the setting refers to a directory, then CURLOPT_CAINFO doesn't
work (must be a file). Check this and use CURLOPT_CAPATH instead.
Caveat: there are some comments in the API documentation about "NSS
enabled libcurl" which supports a directory in
CURLOPT_CAINFO. Hopefully providing an explicit path in CURLOPT_CAPATH
also works in that configuration.
* code cleanup + rewrite: syncing done in separate process
syncevo-dbus-server now runs syncing in a separate process. Local
sync also uses a second helper process. This makes the D-Bus server
more responsive via D-Bus (no more blocking operations) and
minimizes the effect of bugs in code involved with syncing
(backends, system libraries, etc.).
In the long term this restructuring will also allow more advanced
features, like monitoring local or remote storage for changes.
* SyncEvolution <-> SyncEvolution sync: multiple cycles per session
SyncML only allows one send/receive cycle per session. There are cases
(for example, client side merges data that a dumber server failed to
match correctly) where client and server are still out of sync at
the end of a cycle. When SyncEvolution syncs with another SyncEvolution
instance (locally or remotely), both sides detect that the peer
can continue syncing in the same session and start over automatically
when needed. Previously the user had to start another sync session manually.
To the user this is shown as "number of cycles" in a sync session
in the sync report. "Restart" is the process of entering a new cycle.
The cycles are also visible in the command line output as multiple

* SyncEvolution <-> SyncEvolution sync: negotiate UID support via SyncCap (BMC
The semantic of UID/RECURRENCE-ID in calendar data is now tracked
per data store involved in a sync. If full iCalendar 2.0 semantic
(= IDs are globally unique) is guaranteed, then pairs are found
based on these IDs. Otherwise pairs must be found by looking at
Previously a hack was used to detect this kind of support (any kind
of SyncEvolution instance was assumed to support it, although some
backends do not).
packages: fixed D-Bus server autostart in .deb and .rpm packages
syncevo-dbus-server wasn't started automatically as part of a user
session because /etc/xdg/autostart/syncevo-dbus-server.desktop wasn't
included in the packages. This broke auto syncing after a session
restart (required manually starting SyncEvolution).
packages: support KDE
The traditional "syncevolution-evolution" package was
replaced with "syncevolution-bundle". A meta
package depends on it, to support seamless updates for users who have
Binary dependencies of the main .deb are ignored for backends
because loading them is optional. The new "syncevolution-kde"
package has the right dependencies for KDE/Akonadi, while
"syncevolution-evolution" mostly just lists standard libs
if the "EDS compatibility" mode is used, where libebook/libecal
are loaded dynamically.
Platform specific code (GNOME keyring, KDE wallet) was moved into
loadable, optional modules, to allow installation of the SyncEvolution
bundle without forcing the installation of unused system components.
* D-Bus: use GIO D-Bus instead of libdbus if available
When compiling from source, the more modern GIO D-Bus is used instead
of libdbus if available and recent enough (>= 2.30). syncevolution.org
binaries still use libdbus, to stay compatible with older Linux
* several minor bug fixes
syncevo-dbus-server now runs under valgrind in the nightly testing,
plus several more test scenarios were added. This helped to find
and fix various minor memory handling issues.
* developers: backend API changes
beginSync/endSync() (aka m_startDataRead/m_endDataWrite) may now be
called multiple times per SyncSource instance life cycle. SyncSources
derived from TrackingSyncSource should work without changes. Use the
Client::Source::*::testChangesMultiCycles test to check whether your
backend supports this correctly.
Reading and deleting must throw a 404 status exception when an item
is not found. The Client::Source::*::*404 tests cover this.
The special semantic of the former RegisterSyncSource::InactiveSource
(invalid pointer of value 1) caused bugs, like using it in
--print-databases (=> segfault) or not being able to store the result
of a createSource() directly in a smart pointer (=> potential leak in
Obviously a bad idea to start with. Replaced with a
RegisterSyncSource::InactiveSource() method which creates a real,
inactive SyncSource instance which can and must be deleted by the
This is a SyncSource API change for backend developers. Instead of
RegisterSyncSource::InactiveSource(). Comparisons against
RegisterSyncSource::InactiveSource needs to be replaced with a call
to the new SyncSource::isInactive().
Long-running backend calls are encouraged to check for events on the
main glib context (either in a loop or with
g_main_context_iteration(NULL)) and abort when
libgdbussyncevo is now installed as a normal library in /usr/lib,
even though SyncEvolution is the only user.
pcrecpp is now a new hard dependency.
Upgrading from release 1.2.x:
The sync format of existing configurations for Mobical (aka Everdroid)
must be updated manually, because the server has encoding problems when
using vCard 3.0 (now the default for Evolution contacts):
syncevolution --configure \
The Funambol template explicitly enables usage of the
"refresh-from-server" sync mode to avoid getting throttled with 417
'retry later' errors. The same must be added to existing configs
syncevolution --configure \
Upgrading from releases before 1.2:
Old configurations can still be read. But writing, as it happens
during a sync, must migrate the configuration first. Releases >= 1.2
automatically migrates configurations. The old configurations
will still be available (see "syncevolution --print-configs") but must
be renamed manually to use them again under their original names with
older SyncEvolution releases.
