[long answers first, short one at end] because, despite being an absolutely critical strategic project that could save key strategic free software projects who are _not_ using it about a man-decade of development effort _each_, there is absolutely zero recognition of this and therefore absolutely zero funding of the project. luke howard uses freedce for his XAD project, which is a (proprietary) Active Directory replacement that he released THREE YEARS ago (and the samba team _still_ haven't got an active directory server replacement yet). XAD is capable of running on IBM z390 mainframes, and luke howard has won business awards for his work. because, as it is "old" code, with a very archaic and interesting development history, it needs work to be brought up-to-date. and because it needs work, and _because_ it is so very comprehensive in what it does, people misunderstand and do not appreciate its complexity, and therefore think, "i can do better than this", and fail miserably, and so it gets ignored. the gist is this: the use of cancellation is embedded very deeply into the design of this code. and there isn't anyone with the time, money, resources or immediately-available knowledge to rip a quarter of a million lines of code apart looking for a way to shoe-horn some very complex and subtle interaction _out_ of freedce so that it fits nicely with POSIX. anyone think i should try to put the "emulation" bit back into dcethreads (to re-wrap the cancellation rules of posix draft 4 but to keep the new API) and write redhat off (just like charles advised right at the beginning of this thread), let me know. l.

The above is not true. Some default file icons are controled by the operating system, like .txt, .jpg, or .bmp for example. They can be over-ridden by 3rd party apps. This is a valid bug report.

Re: Race in rpc__cn_network_receiver()?

Re: [Qemu-devel] Reactos SVN + Kqemu fails

by WaxDragon

I just did some digging around, and this issue was introduced somewhere between 20902 and 20911. Alex was working on the kernel heavily at the time, and there are several intertwined commmits IIRC. I just tested 20902 with both kqemu (and -kernel-kqemu) and it installed fine, and ran as well as I remember it did. It was noticably faster.

> From: greatlrd(a)svn.reactos.org > > Log: > fix 16 to 16 soyrce dest why the hell does th 16bitmap surface calls > into this The "16 -> 16 copy" in the DPRINT1 is a copy/paste mistake, it should read "24 -> 24 copy". Your fix is incorrect. What needs to be done in this case is process one pixel at a time, calling XLATEOBJ_iXlate on each one. GvG

gdb question

by Saveliy Tretiakov

Hi. I'm trying to debug ros with gdb (according to GvG's tutorial) and I have a problem. After I attach gdb, reactos boots into desktop and then freezes with endless sigservs. Mouse cursor is not moving. Any ideas?

Maybe somebody forgot to run "svn add inet_ntop.c" before they committed their changes?
