SmartPDF (aka SumatraPDF) in rosapps, linking problems
by Klemens Friedl 02 Oct '07

02 Oct '07

SumatraPDF is a lightweight Win32 pdf viewer app http://blog.kowalczyk.info/software/sumatrapdf/ http://code.google.com/p/sumatrapdf/ The name "sumatra" sounds weird (for an app), so I renamed the directory and the output exe file to "SmartPDF" (based on suggestions from #reactos). SumatraPDF comes with VS 2k5 project files. I have fixed various compile issues so that libjpeg, poppler, fitz/mupdf and sumatra app itself compile without errors in mingw (RosBE 0.3.7.2 Win32). All code changes can be found by grep/search for "@note:", I added a comment to each changed code line. The remaining problem is the linking issue. Currently it does NOT link correctly. Timo Kreuzer mentioned on 2007-09-27 in #reactos something that may be related to the issue: "it [sumatrapdf] imports a function from winspool.drv by number, when you add that number to winspool.def, it starts" Please have a look at it, fixes are appreciated :) Klemens

Kernel streaming header mess / GUIDs
by reactos-development＠silverblade.co.uk 30 Sep '07

30 Sep '07

Hi, Alex nudged me in IRC about this, but sadly I've not quite figured this out yet. It appears my definitions for Kernel Streaming GUIDs are not quite right. This results in ugly code like so: -- const GUID foo_audio_category = STATIC_KSCATEGORY_AUDIO; DoSomethingWithTheGuid(&foo_audio_category); -- Which consequently results in a barrage of compiler complaints about brace initialization. It should be possible to just do: DoSomethingWithTheGuid(KSCATEGORY_AUDIO); I'm clearly going wrong somewhere in KS.H or KSMEDIA.H but to be honest am blind to whatever is causing the problem. If anyone can figure out what I'm doing wrong here, I'd appreciate it. Thanks. -Andrew

Re: [ros-dev] [ros-diffs] [fireball] 28351: Dmitry Chapyshev <lentind@yandex.ru>: - Fix so that letters like "p" or "y" are correctly displayed in messageboxes.
by Ged 29 Sep '07

29 Sep '07

IMO, this change is wrong, it's a hack to a problem we have with text placement. Text is cut short on other controls too, not just messageboxes. Check out labels for example.

Note for devs about translations
by Heis Spiter 29 Sep '07

29 Sep '07

Hello, I'd just like to do a remark about ReactOS apps, dlls, which be translated. When a dev change something to the interface, or the core app, it could be great to update EVERY language file (*.rc) and not only some of them (or even worse : only english one). It does not take many times to do (I know because I've already done that), and for a translator that's quite easier to see what has changed without having to compare his language file and the english one. And most of all, it avoids uncomplete, or outdated language files. Finally, for end-user, that's better : that's even better to have English string instead of nothing (I mean blank string). Thanks, Pierre Schweitzer, French Language Maintainer

The word "tainted" is actually quite wrong, and is being misused everywhere. A tea was tainted by polonium in a not-so-recent accident in the UK. ReactOS is not a tea, and we have no "polonium" commiters. There will be a WineConf event in 1 or 2 weeks, and they say they are going to clear up the legal situation around Wine, around SFLC audit and around requirements to the developers, whose code may be commited to the tree. When they do it, I would be very glad to know those requirements, and enforce them on ReactOS developers, so that we are on the common ground. > > Well, if the project is going to wait until more modules stabilize, > won't > this stabilization process obfuscate most of the tainted source > code, and > make them hard to find? Your mind is ahead of you. "Taint obfuscated code", "Obfuscate tainted code", ... Your question is obfuscated and may be tainted, I won't answer it. WBR, Aleksey Bragin.

Please stop rumouring this topic. I clearly said "if there are strong circumstances, in future, only then we will think about doing 3rd party audit, and only from agreement of all devs". That's 3 or 4 years away from now, if such legal problems ever happen. Also noone ever said SFLC is taking up copyrights to themselves. At least it's first time I hear this. I just grepped Wine source code base for word "SFLC" - doesn't appear anywhere. Also, open up any of Wine's source code file, you'll see "Copyright 200x Person's Name". And again, I didn't suggest SFLC or FSF or whoever. Time will show who and if we need, and who and if agrees to. WBR, Aleksey Bragin.

Well-well, please calm down, we had enough flamewars, a new one is not necessary. No decisions are made, and no decisions are going to be made without agreement with all our developers.

Re: [ros-dev] Open Sound System porting
by reactos-development＠silverblade.co.uk 23 Sep '07

23 Sep '07

Thanks for all the replies so far. I find it quite insane that MSDN compares ioctl to DeviceIoControl. Whilst they achieve the same results, the actual parameters used etc. are entirely different. I'm not sure if Steven's suggestion would work (ie, use ws2_32) since, to my knowledge, that particular implementation is specific to sockets. Probably the best way around this then, would be to make an ioctl wrapper that takes the OSS-specific IOCTL codes, and translates them into custom NT IOCTL codes. The wrapper would take things like structures being passed via the ioctl and send them via DeviceIoControl instead. It does seem like a fair amount of work but if an appropriate "wrapper" is created, it could work...

Audit
by Aleksey Bragin 22 Sep '07

22 Sep '07

Hello, I recently asked Klemens to remove audit progress bar from the frontpage. Some wonder: why? The simple answer is obvious: Audit doesn't have anything to do with end-users, testers, or patch- submitters of the project. Audit is an effort run by ReactOS Development Team, and has only one goal: Reduce possible legal problems in future, when, and if, ReactOS starts to have commercial appliances. The process with file locking-unlocking is only the top of the iceberg, there is a huge amount of work to be done in order to maintain solid legal base for all our code. It can't be measured with a single progressbar, nor it needs to. It can't be done only with the help of ReactOS Development Team, a third party code reviewer is a must. We plan that too, but for later time, when there are more stable modules in ReactOS. Legal base consists of a number of factors: authorship and sources of the code and their legality, availability of documentation for certain interfaces and algorithms, development of test cases showing internal behaviour of certain API functions, licensing issues, 3rd party code reviewing process results, etc, etc, etc. I think it's rather clear to see that measuring all the above factors in a single percentage number can't sound serious for a project, nor can it be a real value of cleannes of the project. The respective Audit wikipage needs to be updated too WRT this email. Also please note, our audit process results are fully seen via SVN commits, so there is no hiding involved. With the best regards, Aleksey Bragin.
