[dev] Make component unloading possible again on *NIX
Hi,
with the 3.0 Linux baseline being glibc-2.2.3, maybe it's time to
enable dlclose() again in osl_unloadModule()?
From the atexit manpage:
Since glibc 2.2.3, atexit() (and on_exit(3)) can be used within
a shared library to establish functions that are called when
the shared library is unloaded.
Cheers,
-- Thorsten

[dev] moving psprint into vcl
Hi all, for various reasons we (hdu and me in this case) would like to move the code now residing in psprint into vcl. reasons to do so: - font subsetting code is in psprint and on many platforms linked statically into vcl anyway. - future CUPS versions will migrate from PostScript to PDF as their primary spool file format. moving psprint to vcl will make it easier to do this migration in OOo, too. - vcl is psprint's only customer anyway. - there is code duplication between psprint and vcl currently that can be removed after this changed. However this will mean there will be a CWS that will make this migration and changes to psprint in other CWS will be moot (see the discussion about svn not warning about committing to moved files). So consider yourself warned that we will announce a time at which no changes to psprint should be made until a certain CWS is integrated (not that there are that many people doing that anyway :-) ) At the same time we could do a little cleanup and first thing coming to mind is the MACOSX specific code which could be removed. That would however mean that the old MacOSX X11 port would not really work anymore (at least WRT to printing). So I want to ask: do we really continue to have the X11 Mac port in the 3.0 line ? Are there any compelling arguments for this ?

And to be honest, I think 2.4.3 (I still continue to believe maxleofix4x11 will be integrated a day) is the very last version to have X11 working, and I agree to no longer support it in 3.x line.

We are going to split off a separate OOo 3.1 code line soon. Only 3.1 tasks will be accepted there. Having psprint code inside vcl on TRUNK and in a separate module on 3.1 branch for several months sounds like a maintenance nightmare.

Please see issue 97829 (http://www.openoffice.org/issues/show_bug.cgi?id=97829) to track this. The idea to support the different APIs is simple: - on OSX 10.4 to 10.x use ATSUI - from OSX 10.(x+1) use CoreText There is just the problem that this is time-consuming SMOP (simple matter of programming), which needs to be coded and tested thoroughly. Layout incompatibilities with documents done with an ATSUI code base should be avoided. And there is the minor problem that we currently build for a 10.4 baseline. I just created the issue to track it. That task has currently a relatively low priority. -- Herbert - To unsubscribe, e-mail: dev-unsubscr...@openoffice.org For additional commands, e-mail: dev-h...@openoffice.org

[dev] @Eric: Software Engineering Students Open Source development
Hi Eric Happy to meet you and interesting stuff you are doing as I see from the information and links you provided!!! This seems actually very close to the work I am currently engaged at with Aristotle University. I suggest that the two of us have a short IRC chat / phone conversation to check for synergies -- just tell me at which time I can find you at the channels you mentioned. Just to have it mentioned and avoid confusion, I am not actually giving this software engineering course, but have worked with Prof. Ioannis Stamelos (who gives the course) for the past 3 years in another project and now volunteered to help at this pilot course. I am supporting the course more from the virtual and organizational side. Volunteered also means we do this without funding, like you, so with equally limited resources. It would be great to explore some common actions, such as the live events we now consider running. I have been running several IRC sessions with some of the students last year, and it was good to get further the current work they are doing and to provide assistance. The sessions at UStream I thought of would be more of an informative / introductory nature. UStream allows the host to videocast meanwhile the audience is participating by chat. This should be moderate in terms of required bandwith and equipment to participate at such an event. One advantage is that the session will be recorded (including the chat log), so it is preserved for others / future students. The service is also free, like almost all of the things one needs today -- which is a great advancement educational wise. Chats certainly are always a plan B. Playing at the web on a daily base as part of my research I think that you can do a lot of funky things, with very limited sources -- though certainly the HR aspect is the crucial one nowadays. I heard already about Seneca from various sources, so apparently they also do some interesting things. Btw: Glad you forwarded my mail to the educational list -- I now subscribed to it too! Hope hearing from you again!

We are currently piloting an open approach for the course Introduction to Software Engineering (ISE) at Aristotle University in Greece, That's a great idea. And I'm sincerily glad to read such news : you have all my encouragements ! aimed at bringing together Aristotle students, students from fellow universities, open source practitioners and anyone else interested in SE. As professor myself, in a french engineer school, I try to do the same with my students, and I perfectly understand what your need is. To facilitate the students entrance to open source projects we are now trying to organize some live events for Jan / Feb 2008 (chats, video sessions or pod casts at ustream) that would introduce the students to some aspects relevant to working in open source environments. If you are interested, I propose to discuss directly about that on IRC (see below for the channel/server). Therefore I wondered if anyone here might be interested in chairing one of those live events and to talk (A) about OpenOffice in general, some experiences and challenges, ways to contribute to it, etc and (B) about a more generic topic relevant for newbies (e.g. understanding the code, etc). In my free time, as myself developer for OOo since several years (mostly Mac OS X port), and involved in mentoring students since several years two (twice Google SoC mentor, and some other), and I sincerily think OpenOffice.org Education Project can answer such request and organize such event successfully. In fact, we are used to do IRC meeting as ClassRooms. Please notice we use IRC, because people attending are from all around the world, and not everybody has a good connectivity.
