Wine Time Line
by Thomas Wickline Nov. 15, 2002

Nov. 15, 2002

Hi, I have been looking over the FAQ and we have a question in the FAQ " What is the History of Wine" And after talking with Dimi Paun I would like to expand this to a " Wine Time Line" page that could be updated a couple times a year. This would give users info about wine's progression & events that took place over the years. Here is a draft of the first year 1993/1994..... Done by _Robert Amstadt_ -- A discussion began on USENET about the feasibility of running Windows apps on Linux. There were some people that said that it is impossible. This didn't sit well with Robert Amstadt so he began work to prove them wrong. He started out by writing a program loader for Win3.1 apps. Alexandre Julliard merged windowing functions written by Peter MacDonald in Tcl/Tk to the program loader written by Robert. Alexandre soon after rewrote everything to eliminate the Tcl/Tk in favor of direct calls to Xlib. Eric Youngdale also contributed early in many areas including improvements to the program loader. The very first Wine mailing list was operated by Robert to allow discussions between developers. After a year with many successes and growing interest in the project we asked for the creation of the newsgroup comp.emulators.ms-windows.wine. The vote was overwhelmingly in favor of its creation. Around the same time, Robert was asked to give a presentation about Wine at the first Linux Congress in Heidelberg, Germany. The room was packed. Interest in Wine was very high. During the first year of development, most of the code was written by Alexandre Julliard and Robert Amstadt. However, we have always received contributions of code from many people. Life got busy for Robert and he stepped down as head of the project and let Alexandre take control. It was probably sometime during the second year. -- Thoughts, Volinteers, Flames are most welcome..

First of all it was just an example what it could be used for. It is the only thing that winapi_test (tests/generated.c) currently tests for. However, there will be more tests in the future testing for other things that might or might not be C++ dependent. Secondly the test makes certain that you don't have a #ifdef __cplusplus affecting some structure by mistake. And yes, there are structure like that MONITORINFO that does. And no, don't look in the Wine source, it doesn't implement it yet. Then we could have #ifdef __cplusplus that have an "missing" #endif that matches some other #endif in the wrong place or something. We also have the COM interfaces that are different in C++... Then of course we want normal C++ tests as well. Many (most?) applications likely to be ported by Winelib are C++ application so we really should have tests for possible C++ problems. But it you don't like the .c.cxx hack I could generate C++ tests to a generated_cxx.cxx or whatever then we don't need that part of the patch. It is a little ugly I admit. :-)

dsl file for sgml faq
by Vincent Béron Nov. 14, 2002

Nov. 14, 2002

Finally, it's done. In the attached archive you'll find the following files: wine-faq.sgml -> Main sgml file faq-0.sgml \ faq-1.sgml |-> Content sgml files faq-2.sgml / faq.css -> CSS file for the FAQ index.html -> The output of docbook2html -d faq.dsl wine-faq.sgml authors.ent -> same as in documentation/, wasn't needed actually. faq.dsl -> Definition file for docbook. This is where the work went. I modify a few docbook definitions to match Dimitrie's layout. Not obvious without knowing LISP beforehand :) Of course, if somebody chooses another layout, some of this will need adjustment. Or if we prefer something closer to "vanilla" docbook. Dimitrie, the actual HTML code is rather ugly in it's source presentation, so don't hand-edit it :P Anyway, it's not meant to be hand-edited, that's what sgml and docbook are for. The layout is exactly what you already have, although with some small modifications to the layout the dsl file can be alot simpler. Tony, you can begin the transition if Dimitrie likes it (and when you have the time to). That's all for tonight. Vincent

The security community regard the introduction of fam > a serious backward step on RH's part. Sounds like someone is misinformed, because we don't have it listening on external ports. That's only required to make it work over NFS or something.

GNUCash has something like 40 dependencies including a lot of very unstable/unfinished APIs. FAM is 1 dependency and while it sucks, it doesn't change very often (or at all that I know of). Alex Larsson wanted to work on a nicer FAM-type thing based on a per-user daemon or something, but hasn't had time. Certainly there's room to write such a thing, but I don't think it's harmful to use FAM if FAM is present. It's not like a FAM dependency would be pervasive, it would be small and well-isolated and easy to change to some other dependency if you found something better. Havoc

It all depends which platforms you want to support in this patch, as far as it goes. FAM has support for a lot of different systems, but there's no need to really add it as a dependency IMHO. Adding support for the platforms we wish to support would be simpler. I think the best reference would be to use F_NOTIFY under Linux. This makes writing FindFirstChangeNotification a maybe 20 minute job. The simplest example I can think of is from Samba: http://cvs.samba.org/cgi-bin/cvsweb/~checkout~/samba/source/smbd/notify_ker… It's GPLed, so only use it as an example, don't copy code from it :) Other platforms have other methods (eg, FreeBSD you can use kqueue/kevent).. so yes, it all depends how much compatability you want. On other platforms you can always resort to polling, but this is quite horrible. I think NetBSD has a kqueue/kevent method, but IIRC it's broken. :) - Ender

Filesystem change notifications
by Ian Pilcher Nov. 14, 2002

Nov. 14, 2002

Is anyone working on implementing FindFirstChangeNotification and friends? If not, this looks like something that may be both within my capabilities and non-trivial enough to be useful (a rare combination!). My thought is to use SGI FAM (http://oss.sgi.com/projects/fam/) which is shipped with Red Hat and (according to bug #588) Mandrake. I'm not sure about any other distributions, but the FAQ on the web page states that Enlightenment, GNOME, and KDE all use it, so it should be pretty widespread. If no one is working on this, start preparing for an endless series of questions about the wineserver's internal workings. -- ======================================================================== Ian Pilcher pilchman(a)attbi.com ========================================================================
