[SyncEvolution] SyncEvolution 1.5.1 released
by Patrick Ohly
About SyncEvolution
===================
SyncEvolution synchronizes personal information management (PIM) data
via various protocols (SyncML, CalDAV/CardDAV, ActiveSync). It syncs
contacts, appointments, tasks and memos. It syncs to web services or to
SyncML-capable phones via Bluetooth.
Binaries are available for Linux desktops (using GNOME Evolution, or
KDE's Akonadi), for Maemo (Nokia N900, N9) and Sailfish OS (Jolla
phone).
About 1.5.1
===========
Maintenance release. Binaries now also get compiled for Debian 8.0
"Jessie".
Details:
* avoid time zone issue with Funambol server
The Funambol iCalendar 2.0 parser fails to handle time zones
with quotation marks around the TZID value, which is something
that SyncEvolution started to add in 1.4.99.3. While it is valid
to quote like that, it is not necessary, so avoid quoting in
this case to restore interoperability.
* syncevo-http-server: stop using deprecated twisted.web.error (FDO #90419)
This has become a real problem for example on Fedora 22 where the
old name is no longer available.
* syncevo-http-server: use TLS instead of SSLv3
This fixes a potential security risk and connection problems with clients
that don't support SSLv3 anymore.
* syncing: avoid segfault for invalid text inside items (FDO #90118)
As reported by Canonical, syncing fails if data items contain
text which is not correct UTF-8 in one of the fields that
SyncEvolution logs in the command line output (like SUMMARY of
a calendar event).
That is because the byte string coming from the item is passed
unchecked to the D-Bus implementation for transmission via D-Bus. But
D-Bus strings must be correct UTF-8, so depending on the D-Bus library
in use, one gets a segfault (GIO D-Bus, due to an unchecked NULL
pointer access) or an "out of memory" error (libdbus, which checks for
NULL).
SyncEvolution now replaces invalid bytes with a question mark in its
output while preserving the rest of the text.
* file backend: log item manipulation
Extracting a meaningful description of each item from the Synthesis
engine when updating and adding items is easy to do for items of
certain known types (contacts and calendar items).
* command line: preserve log prefix of target side of local sync
In some cases, the prefix which was supposed to be embedded
in the log messages from the target side of a local sync got
lost on the way to the command line tool.
Primarily this affected the added/updated/deleted messages, as in:
[INFO remote@client] @client/addressbook: started
[INFO remote@client] updating "Joan Doe"
[INFO remote@client] @client/addressbook: received 1/1
* compile fix: use ${PKG_CONFIG} instead of pkg-config.
This fixes the build on Exherbo that only has prefixed versions of
pkg-config.
* WebDAV: handle 403 during Google OAuth authentication
When sending an access token with insufficient scope (for example,
because the Ubuntu Online Accounts service definition was incomplete,
as documented in FDO #86824), Google responds with a 403 "service
denied" error.
This is now dealt with by retrying, just as for a transient 401 error.
* CalDAV: more efficient "is empty" check (FDO #86335)
Since 1.4.99.4, syncing WebDAV collections always checks first
whether there are items in the collections. This was partly done for
slow sync prevention (which is not necessary for empty collections),
partly for the "is the datastore usable" check.
However, this did not take into account that for CalDAV collections,
the entire content gets downloaded for this check. That is because
filtering by item type (VEVENT vs. VJOURNAL) is not implemented
correctly by all servers. So now all CalDAV syncs, whether incremental
or slow, always transfered all items, which is not the
intention (incremental syncs should be fast and efficient).
This release adds a more efficient isEmpty() check: for simple CardDAV
collections, only luid and etag get transferred, as in
listAllItems(). This is the behavior from 1.5.
For CalDAV, a report with a filter for the content type is used and
the transfer gets aborted after the first item, without actually
double-checking the content of the item. This is different from
listAllItems(), which really transfers the content. This extra content
check would only be needed for some old servers (Radical 0.7) and is
not essential, because reporting "not empty" even when empty is safe.
* WebDAV: send Basic Auth via http in some cases (FDO #57248)
It turned out that finding databases on an Apple Calendar server accessed via
http depends on sending Basic Auth even when the server does not ask for it:
without authentication, there is no information about the current principal,
which is necessary for finding the user's databases.
To make this work again, sending the authentication header is now forced for
plain http if (and only if) the request which should have returned the
principal URL fails to include it. This implies sending the same request
twice, but as this scenario should be rare in practise (was only done for
testing), this is acceptable.
* Ubuntu Online Accounts: support plain text credentials
The backend for UOA was rewritten by Alberto Mardegan and now also
can use plain username/password credentials stored in UOA.
* various compiler error and warning fixes

http://syncevolution.org/blogs/pohly/2015/syncevolution-151-released
Source code bundles for users are available in
https://download.01.org/syncevolution/syncevolution/sources
and the original source is in the git repositories
http://cgit.freedesktop.org/SyncEvolution/
i386, lpia and amd64 binaries for Debian-based distributions are
available via the "stable" syncevolution.org repository. Add the
following entry to your /etc/apt/source.list:
deb https://download.01.org/syncevolution/apt stable main
The GPG key for the repository needs to be imported as root with:
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys B2EC3981
Then install "syncevolution-evolution", "syncevolution-kde" and/or
"syncevolution-activesync".
These binaries include the "sync-ui" GTK GUI and were compiled for
Ubuntu 10.04 LTS (Lucid), except for ActiveSync binaries which were
compiled for Debian Wheezy, Ubuntu Saucy, Ubuntu Trusty an Debian
Jessie. The packages mentioned above are meta-packages which pull in
suitable packages matching the distro during installation.
Older distributions like Debian 4.0 (Etch) can no longer be supported
with precompiled binaries because of missing libraries, but the source
still compiles when not enabling the GUI (the default).
The same binaries are also available as .tar.gz and .rpm archives in
https://download.01.org/syncevolution/syncevolution/. In contrast
to 0.8.x archives, the 1.x .tar.gz archives have to be unpacked and the
content must be moved to /usr, because several files would not be found
otherwise.
After installation, follow the
http://syncevolution.org/documentation/getting-started steps.

[SyncEvolution] KDE5 support
by Tino Mettler
Hi Patrick,
the Debian project plans to remove QT4 from the next stable release
(Buster). This means that the Akonadi backend needs to be ported to
KDE5 so it can be shipped with Buster. Do you have any plans for this?

[SyncEvolution] SSL related regression in 1.5.3
by Tino Mettler
Hi Patrick,
while testing the 1.5.3 Debian package, I discovered a regression
regarding the SSL settings.
With the following setttings I only get soup a related error:
SSLVerifyServer = 0
SSLVerifyHost = 0
The error message is:
[INFO] SoupTransport Failure: https://<my host>/sync via libsoup: Unacceptable TLS certificate
When I set both settings to 1, it works as intended.
It also works when I set only one of both settings to 0, or set both to
1.
>From my point of view, people using HTTPS this way (both set to 0)
should just fix their setup, but I don't know if someone really is
required to use such SSL settings. The description in the sample
config reads as if "SSLVerifyHost" is disabled when setting
"SSLVerifyServer" to 0.

Tino

[SyncEvolution] SyncEvolution 1.5.3 released
by Patrick Ohly
About SyncEvolution
===================
SyncEvolution synchronizes personal information management (PIM) data
via various protocols (SyncML, CalDAV/CardDAV, ActiveSync). It syncs
contacts, appointments, tasks and memos. It syncs to web services or to
SyncML-capable phones via Bluetooth.
Binaries are available for Linux desktops (using GNOME Evolution, or
KDE's Akonadi) and the source code also supports the Trinity Desktop
Environment (TDE).
About 1.5.3
===========
Maintenance release. syncevolution.org binaries are now getting
compiled for distros >= Ubuntu Xenial 16.04 LTS. Usage of deprecated
libraries (GNOME keyring) and APIs (SoupAsyncSession) was
replaced. libical v3 is supported.
The code now compiles more cleanly with recent compilers and depends
on C++11 support.
Details:
* EDS: more generic open retry handling
Recent EDS started to exhibit race conditions when opening a database (for
example, https://bugzilla.gnome.org/show_bug.cgi?id=791306). Opening was
already tried again for a certain known error in some old EDS version. Now it
is tried five times with a delay of one second for all errors.
* SoupTransportAgent: require libsoup 2.42, no deprecated methods
This allows us to get rid of deprecated function calls. We no longer
need to set a default proxy either, the newer libsoup does that itself
by default.
* C++: replace auto_ptr with unique_ptr, require C++11
auto_ptr has been deprecated for a while now. unique_ptr can
be taken for granted now, so use that instead.
* testing: work around Google CalDAV RECURRENCE-ID
Stand-alone events with RECURRENCE-ID get mangled by the server:
it converts the RECURRENCE-ID time to UTC. Reported in:
https://stackoverflow.com/questions/47811670/detached-recurrence-without-...
* GNOME: replace gnome-keyring with libsecret (FDO #104219)
The GNOME keyring library has been obsoleted for a long time now,
long enough that the replacement libsecret is available on all
supported distros. Therefore we can switch unconditionally.
* libical: support libical v3 (FDO #104220)
libical v3 removes some deprecated functions (like icaltime_from_timet)
and removes the "is_utc" member from icaltimetype. The replacement
code works with old and new libical and thus needs no ifdefs.
Original author: Milan Crha
* syncevolution.org: fixed packaging (FDO #98014, FDO #100549)
The activesyncd package missing dependencies on libgnome-keyring0 and
libglib2.0-bin and therefore failed to work when installed on a minimal
system without those.
* various build and test fixes/workarounds

Source code bundles for users are available in
https://download.01.org/syncevolution/syncevolution/sources
and the original source is in the git repositories
http://cgit.freedesktop.org/SyncEvolution/
i386 and amd64 binaries for Debian-based distributions are
available via the "stable" syncevolution.org repository. Add the
following entry to your /etc/apt/source.list:
deb https://download.01.org/syncevolution/apt stable main
The GPG key for the repository needs to be imported as root with:
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 43D03AD9
The signing key was renewed for this release. If the key was already
added earlier, refresh it with:
apt-key adv --keyserver keyserver.ubuntu.com --refresh-keys 43D03AD9
Then install "syncevolution-evolution", "syncevolution-kde" and/or
"syncevolution-activesync".
These binaries include the "sync-ui" GTK GUI and were compiled for
Ubuntu 16.04 LTS (Xenial) and should be compatible also with more recent
distros. ActiveSync binaries were compiled for Debian Stretch, the upcoming
Debian Buster (based on current Testing), and Ubuntu Xenial. The packages
mentioned above are meta-packages which pull in suitable packages matching
the distro during installation.
Older distributions can no longer be supported with precompiled binaries
because of missing or incompatible libraries, but the source should still
compile on older distros.
The same binaries are also available as .tar.gz archives in
https://download.01.org/syncevolution/syncevolution/. In contrast
to 0.8.x archives, the 1.x .tar.gz archives have to be unpacked and the
content must be moved to /usr, because several files would not be found
otherwise. When using activesyncd, run "glib-compile-schemas
/usr/share/glib-2.0/schemas" as root after unpacking the archive.
rpm packages are no longer provided due to lack of demand; SyncEvolution
is provided by Fedora as a distro package.
After installation, follow the
http://syncevolution.org/documentation/getting-started steps.

[SyncEvolution] "Sync now" button in sync-ui is disabled
by Tino Mettler
Hi Patrick,
I did some updates to the Debian packages but some final testing
revealed that the "Sync now" button in sync-ui is disabled. Syncing via
command line works fine.
The changes to the old packages are commit 8765654ff355aed3b982bd965e98c00dfd19d1c3
(libical: support libical v3) in libsynthesis and ebf34f9ffe8bf575e1a20beb069ef287366d8ed8
(GNOME: replace gnome-keyring with libsecret) as well as f94ea6df6847d045db7a45fe8b4cfa0b344dfc58
(libical: support libical v3) in syncevolution.
I have to admit that I don't use sync-ui myself but only check if it
works when preparing an update, so I can not tell when it really
stopped working. Due to the libical3 transition I can't really check if
this also happens with the old package. Any hints how I can debug this?
Regards,
Tino
