[ros-diffs] [jimtabor] 22523: GetGlyphOutline, large wine port. Still testing.
by James Tabor 30 Aug '07

30 Aug '07

Hi, I have it half way done. Run the test program and you can see. Program works in W2k, XP and Wine. mingw32-gcc -mwindows -Os GetGlyphOutline.c -o ggo.exe I stopped messing with it two weeks ago, I needed to work on something else. When testing you can select the alphanumeric character with the keyboard. The original program had "a" but I changed it to "L" something simple to draw at first. You will see the problem. The test program from Dr. Dobb's Journal http://www.ddj.com/184409154?pgno=12 Thanks, James Runs and hides~

Why so small?
by Jason Ward 10 Apr '07

10 Apr '07

The source code for ReactOS is only 30MB. The project has been going for 10 years so why so small? Is there a need for any developers who can program assembler? I use the ReactOS assembler. RosAsm. http://www.rosasm.org Or do you only program in C and C++?

Inability to work on RosDE/TE
by Alex Ionescu 01 Apr '07

01 Apr '07

Hi, I promised a new testing/development environment but unfortunately I cannot pursue my work because nobody has been able to fix rbuild to my requirements. If anyone does want to see the standardized environment I promised, please prod your local ReactOS developer for the following features: 1) *Working* ROS_INTERMEDIATE and ROS_OUTPUT directories. They are broken in many ways: a. Don't work with relative pats. b. Don't work at all for .pch files and/or compilation units. c. Create other sorts of unpredictable errors due to hard-coded strings/directories in makefiles or rbuild. 2) ROS_TOOLS_DIRECTORY. The ability for the tools to be outside the ROS_OUTPUT directory, such as in c:\rosde\tools. Someone committed such a patch but it was reverted without a newer version/fix. a. Also requires making rbuild check if the binaries are present, and if so, NOT to rebuild them. b. Create -forcetools switch to rbuild which would force it to bypass the check in 2a. 3) Tools must be built and work with the -O3 optimization setting. Of course, I won't go into the fact that my request for the other rbuild features such as a graphical dependency map have gone unanswered. Many thanks to those who _have_ worked on some of the MSVC features/bugfixes I brought forward and do the small attempt at a depmap. -- Best regards, Alex Ionescu Project Lead, TinyKRNL Kernel-Mode Software Design Engineer, ReactOS

While I agree in spirit with the revert, we should use DDK #defines for compatibility. Please re-commit that part. -----Original Message----- From: ros-diffs-bounces(a)reactos.org [mailto:ros-diffs-bounces@reactos.org] On Behalf Of fireball(a)svn.reactos.org Sent: March-30-07 11:39 AM To: ros-diffs(a)reactos.org Subject: [ros-diffs] [fireball] 26210: - Revert useless commit: * No need to copy stuff from DDK, it's prohibited (#define _INC_NEWDEV) * #pragma was put there especially, and no reason to remove it was said * pushpack /

Some Questions
by Daniel Nikolić 29 Mar '07

29 Mar '07

I recenly found out about this website. I checked out the sources (great) and tried to run React OS under VMware player (not so great) and even tried some of my sw to run under it (disaster!). I have a few questions: 1. I noted some inconsistencies in handling 8-bit/UTF-16 translation in ..A/..W calls between ...A functions in graphics (TextOut...) and synchronization (CreateSemaphore...). Graphics part always allocates memory (HeapAlloc) - a waste of time, IMHO. 2. I'm, not sure if is there a list of already checked/done, but not verified/not implemented API? 3. How could I help (I know some C) Regards, dn PS Meanwhile, I was reading Doxygen & could not figure out how MultiByteToWideChar() works (=i.e. how you implemented it), but I think it calls RtlMultiByteToUnicodeN(), which implements CP -> UTF-16 mapping for currently selected CP, and RtlCustomCPToUnicodeN() for any other CP. Some my programs use MultiByteToWideChar() with CP_UTF8 which is IMHO NOT implemented!?!? May I work on this (in my spare time)? Is somebody else working on this area?

Is it possible, that one of the official ROS-developer can contact http://scan.coverity.com/index.html to let also searched the ROS-code for bugs?

We'll.... I found out how MultiByteToWideChar (MBTWC) is implemented, and looks OK. But then, there are following issues: 1 some functions (DefWindowProcA) call MBTWC, but with CP_ACP and HeapAlloc ALWAYS (IMHO should be: CP_THREAD_ACP, use some local cache if the 8-bit string is short enough, for performance) 2 some functions (GetMonitorInfoA) call MBTWC using CP_THREAD_ACP 3 yet other functions (RegisterClassExA) call RtlCreateUnicodeStringFromAsciiz and and RtlFreeUnicodeString later (no TEB cache, allocation ALWAYS) 4 and some other functions (CreateEventExA) call RtlAnsiStringToUnicodeString and use cache from TEB 5 other functions use RtlAnsiStringToUnicodeString with allocation, and RtlFreeUnicodeString later. 6 and some other functions (SetWindowTextA) call RtlAnsiStringToUnicodeString and RtlFreeUnicodeString (allocation ALWAYS) Is this inconsistent or what?!

About BUG 2093/2078
by João Jerónimo 27 Mar '07

27 Mar '07

I verified that bug occuring on a Pentium MMX, and then ran the liveCD on bochs with a breakpoint at the faulty instruction... It's a CMOVZ (Conditional MOVe if Zero flag set)... Conditional moves were introduced in Pentium II, but never mind! What *really* matters is that that code looks like resulting from compilation (because of the C calling convention clearly used, and no one uses C calling conventions in handwritten ASM code)... So..... Either this isn't a bug (and recompilation is required for non-default configurations), or there is a -march option when compiling the default LiveCD that shouldn't be there... Personally, I would go for the later... PS: Can I view a symbol map for the freeloader image in the prebuilt liveCD? JJ _______________________________________________________ Yahoo!

SVN upgraded to 1.4.3
by Aleksey Bragin 26 Mar '07

Hello, I just finished upgrading svn.reactos.org to SVN 1.4.3. You should feel noticeable improvements - faster work and less traffic. However, if any problem arise, don't hesitate to email ros-general / ros-dev. For a full list of changes over previous version, please look to http://subversion.tigris.org. With the best regards, Aleksey Bragin.

Re: [ros-dev] Interest in ReactOS and some requets
by Aleksey Bragin 26 Mar '07

26 Mar '07

Hi and welcome, thanks for your offer to help - we were just discussing today in the irc-channel that there are some people in our current team who are willing to guide newbies through the process (get src code, build, run, modify something, try writing something new, send in patches, etc). If you have ability, please join #reactos on freenode irc network. If not, then email is allright (ask questions right here, so other can read and learn too). WBR, Aleksey Bragin.
