Syncevolution 1.1
HARDWARE MODEL (on what HW this bug is uncovered):
PC
BUG DETAILED DESCRIPTIONS
===========================================================
Currently, for starting syncevolution as a http server, 2 commands must be
launched:
1. syncevolution-1.1/src/syncevo-dbus-server
2. syncevo-http-server
Apparently (unless I miss something), the only thing that the
syncevo-http-server frontend does is translate from http to dbus, and the
actual "work" is done by syncevo-dbus-server.
What is the purpose of this? Easy availability of an embeddable http server in
Python (twisted), but not in C++?
I've been googling around a bit, and came across libmicrohttpd:
http://www.gnu.org/software/libmicrohttpd/
This allows to embed a http server in any C or C++ application. Maybe this
would simplify usage of syncevolution in http server mode somewhat?
EXACT STEPS LEADING TO PROBLEM:
(Explain in detail what you do (e.g. tap on OK) and what you see (e.g. message
Connection Failed appears))
===========================================================
Not applicable
EXPECTED OUTCOME:
===================
A single executable for http server
ACTUAL OUTCOME:
===================
Currently, two programs must be launched to set up syncevolution in http server
mode.
USER IMPACT:
===================
Greater complexity.
REPRODUCIBILITY:
(always, less than 1/10, 5/10, 9/10)
=====================================
Always
EXTRA SOFTWARE INSTALLED:

That's one reason. The other is that it was used as a test vehicle for the
D-Bus API. Yet another reason is that the HTTP server might be started/stopped
independently of the syncevo-dbus-server.
I agree that the issue is valid. But I would rather solve it by having
syncevo-http-server do all the work (set up D-Bus session, start
syncevo-dbus-server) when a specific command line option is given.
Of course, patches for integrating an HTTP server into syncevo-dbus-server are
also welcome.

Yes, that would be a good solution too. And as an added bonus, http-server
could kill the dbus-server when the client shuts down its syncml session (if
such a concept exists... else maybe a timeout?)
Of course, patches for integrating an HTTP server into syncevo-dbus-server are
also welcome.
In the near future I'll probably have no time for preparing them, but I might
get around it sometimes next year.
Another alternative would be to have syncevo-http-server behave like a CGI, to
be invoked by Apache. That way the user would not need to bother starting it
up, as Apache would do that for him. And SSL support would be easy to add, as
Apache supports that out of the box.

The problem is the D-Bus session. Evolution Data Server does not work without
it. Starting a new session is okay for a server where the user never runs
Evolution in a separate session, but would be very bad on a desktop system.

I think the following two commits address the problem sufficiently.
alainlux, does this work for you? You can download the new
syncevo-http-server.py from
http://meego.gitorious.org/meego-middleware/syncevolution once it is back
online; currently only git access works.
commit 912f2992e802609d905a7cb99bc065fa3a925fb0
Author: Patrick Ohly <patrick.ohly(a)intel.com>

syncevo-http-server: start syncevo-dbus-server explicitly (BMC #10270)
--start-syncevolution
sets up the right environment for
syncevo-dbus-server
and (re)starts it explicitly, instead of depending
on
D-Bus auto-activation; to be used when
SyncEvolution
is not installed at the location it was compiled
for
--syncevolution-path=PATH
sets the installation path (the directory which
contains 'bin', 'libexec', etc.) to be used
in
--start-syncevolution, default is the location
where
syncevo-http-server itself is installed
Starting syncevo-dbus-server in a synchronous manner similar to the
traditional D-Bus get_object() is tricky. It is currently implemented
as a subprocess spawn, followed by a loop which checks for the
well-known name to appear on the session bus.
Open issues:
- What if syncevo-dbus-server was already running?
- The code is meant to restart syncevo-dbus-server on demand, but that
doesn't work. Once the spawned process terminates, twisted seems to get
stuck handling the SIGCHLD signal for a process it doesn't know anything
about.
commit 4812b391fd6fee4b9692e44426f5a0e1ffae1850
Author: Patrick Ohly <patrick.ohly(a)intel.com>
Date: Tue Dec 28 14:25:17 2010 +0100
syncevo-http-server: added D-Bus session handling (BMC #10270)
--start-dbus-session creates a new D-Bus session for communication with
syncevo-dbus-server and (inside that server) with
other D-Bus services like Evolution Data Server,
removes it when shutting down; should only be used
if
it is guaranteed that the current user will not
have
another session running, because these services can
get confused when started multiple times; without
this
option, syncevo-http-server a) uses the session
specified in the environment or b) looks for a
session
of the current user (depends on ConsoleKit and
might
not always work)

Unfortunately, I can't find any link to syncevo-http-server.py from that page.
Do you maybe have a direct URL? Thanks,
Alain
