[ros-diffs] [jimtabor] 22523: GetGlyphOutline, large wine port. Still testing.

by James Tabor

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~

Re: [ros-dev] [ros-diffs] [dgorbachev] 26483: Undo r26482 change, waste more stack space.

by Alex Ionescu

Perhaps you could try convincing the GCC folks to actually properly support declspec_align like MSVC does, instead of claiming to support it, but actually ignoring it. Then you could also convince them to support SEH, PDBs, STDCALL-default calling convention, etc ;) -----Original Message----- From: ros-diffs-bounces(a)reactos.org [mailto:ros-diffs-bounces@reactos.org] On Behalf Of dgorbachev(a)svn.reactos.org Sent: April-24-07 1:06 AM To: ros-diffs(a)reactos.org Subject: [ros-diffs] [dgorbachev] 26483: Undo r26482 change, waste more stack space.

Re: [ros-dev] About translation

by Aleksey

Hi Lucio, I must say, that there were a lot of efforts to get our tools working as easy as possible. Even a global login system was introduced way back so that you don't need to create an account for wiki, for bugzilla, for forum, for wiki, for the main website - you just create one. A lot of time was spent in order to do this (every piece of software needed to be customised - Ge and Klemens put a lot of their personal time into this). I will answer between the lines below so it makes better sense. ----- Original Message ----- From: "Lucio Diaz" <reactos_translate(a)yahoo.es> To: <ros-dev(a)reactos.org> Sent: Tuesday, April 17, 2007 2:08 AM Subject: [ros-dev] About translation -= skip =- > -Many like me can install SVN, and get the source > code, but never have made a patch, or even used > bugzilla(and probably wont have the time). If a contributor has SO small time that he can't even submit his work to a bugzilla or, at least, send a patch to a relevant person (the same language native speaker developer or another translator who has more time), then it's better to wait when he/she has more free time to contribute. -= skip =- > files, but sending them to bugzilla... i dont know how > to send them to bugzilla, i dont have a bugzilla > acount, it was tiring trying to find someone to send > the files, and i dont have the time or will to learn > bugzilla. That shows you really did not even slightly investigated how the website works. And instead you're proposing a whole workflow for developers, so they mandatory spent a few hours per week maintaining all the stuff you. During that 2 years you should have spent just a bit of time, even 20 minutes, to overview our website and systems we have there, and another 20 minutes to read online manuals/help for them. Excuses like "I didn't have time" hardly apply here. WBR, Aleksey Bragin.

RosBE Chatroom

Hi, I set up a Chatroom for RosBE (Windows/Linux) specific questions. Its on Freenode and is called #reactos-rosbe. I dont know if its so useful, but I was bored and thought this could be useful. Bye.

Re: [ros-dev] [ros-diffs] [dgorbachev] 26893: Do not free the string twice.

by Aleksey Bragin

Actually, I removed the hack from IopCreateDriver, and added a loop to prevent creation of drivers with the same name (which actually have no impact on the servicekeynode). What is the real cause of a double free? And which hack are you referring to in IopCreateDriver? WBR, Aleksey Bragin.

Suggestion for making things a bit smaller

by carlo.bramix

When building the release versions of executables, DLLs, etc, I would suggest to add the "-s" switch to the linker flags. It will do stripping automatically and release-mode objects will be a bit smaller. Alternatively, we could "strip -s file.exe" but just adding the flag would be much simpler.

Write a driver, install it and send a packet to it, so to activate the test. Have the driver dump to WinDbg. > Suggestion to make it a little clearer: > #define BIAS 127 > Exp -+= (BIAS - 2); I know about the IEEE bias. I'm just using my old 68k code that I'm comfortable with. I'll change this later with the Dc handle stuff I'm still testing. Thanks, James
