Re: [Freedce-devel] pthread_clear_exit_np()

christoph, christoph, why are you trying to insult someone who is looking to further the long-term aims and goals of free software, by putting people in touch on perceived unrelated projects and explaining to them the relevance? you have a specific area of expertise (according to your 2005 ukuug bio) - kernel development. i would welcome an opportunity for you to explain why my life, which happens to be quite poignantly sad and unfulfilling in many ways, has any relevance to the discussion at hand - and, also, if you could possibly elaborate on why i am "beeeing an asshole" likewise has any relevance. also: i would strongly advise you to consider objectively what i am trying to do - and forget what you do not know about me [you know nothing about me]. forget that i am involved in this discussion, because it is clearly affecting your (and evidently other people's) objective judgement. freedce is an important and under-recognised project that can save literally man-decades of development time currently being wasted by key free software projects, and lack of recognition for it is also stopping several interoperability projects from even _happening_. you want to know how many incompatible free software implementations there are of MSRPC around? i count FOUR, all written in c. EACH of those projects has had at least two full-time members working on them for AT LEAST three years, and each of those projects will require those full-time members to continue working on those incompatible and fundamentally non-interoperable development environments for another three to five years, to make them useful - as development environments, rather than to "fill one project's needs". [whereas, if one of the fat cat free software "supporting" companies would actually get off their backsides and fund freedce, it would save everybody several decades worth of money] you see - until such time as those non-interoperable MSRPC projects are completed, microsoft still dominates the market. MSRPC is the key infrastructure which binds everything together in the microsoft world: it's what the European Union is trying to get out of microsoft in the anti-trust case: information on how they use MSRPC; how they do their authentication; the IDL files; specifications on the nt domain services; etc. etc. you indicated in an earlier email that (please correct me if my impressions are wrong) that freedce is archaic and therefore irrelevant. nothing could be further from the truth, and your distaste for freedce is very short-sighted. mark, from ibm: you should be advocating to ibm's free software departments to back freedce and to KEEP the employees who worked on DCE 3.0 and move them to freedce and MSRPC interoperability. get some of that multi-hundred-million-dollar free software advertising budget and put a fractional percentage of it behind freedce. you don't have to _like_ freedce. you don't have to like its history. you don't have to like that it is me that is advocating its use. but don't you _dare_ insult me and think it doesn't have any effect. so. i look forward to receiving an apology from you - not for my benefit, but because it will mean that you are willing to demonstrate to the hundreds of people to whom your message has been distributed, and to the thousands of people who will encounter it in the future, that you can be trusted to make objective and important decisions. and that you don't deliberately go out of your way to belittle and bully other people. if you are unable to apologise, then you demonstrate, to me and to others, that you do not deserve any position of responsibility. am i making myself clear? l.

ReactOS Compatibility Database (beta status)
by Klemens Friedl 25 Apr '06

25 Apr '06

The ReactOS Compatibility Database has reached beta status. URL: http://www.reactos.org/support/ The compatibility database has been designed to store application and driver data. Simply click on one of the 5 green start buttons on the frontpage to begin to browse through the database. To submit an application/driver, click on "Submit Application" (menu bar). Please have a look at the help and faq section for more information. The goal of the whole compatibility database is to provide one single unified place where a lot of compatibility data can be found. This has several advantages: For user it is easy to find out which software does already work in ReactOS and how good it work. Everyone (with a myReactOS account) can submit applications/drivers, additional information, vendor data, compatbility test reports, screenshots and post "compatibility forum" entries. In the last few months, several people asked how they could help in the ReactOS project. Now there is a way for people who don't know programming languages, etc., they can now submit their testing results to one place, the compatibility database. Note, in the compatibility database there is a link to the bugzilla related page. >From now on it will be easier for developers to check regression data, etc. There might be some glitches and bugs, if you find some please post a bugzilla bug entry, write a forum entry or write a reply here (mailing list). If someone has suggestions and/or ideas how to improve the compatibility database please write a reply, thx. Klemens Friedl

[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: [Qemu-devel] Reactos SVN + Kqemu fails
by WaxDragon 18 Apr '06

18 Apr '06

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.

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
