Re: [ros-dev] Smaller SVN REL ISO?
by Aleksey Bragin 11 Jun '07

It is possible to compile with this flag, but you need to build it yourself then. Official ISOs are compiled with leanandmean set to no. WBR, Aleksey Bragin.

Smaller SVN REL ISO?
by carlo.bramix 11 Jun '07

11 Jun '07

Is the SVN REL Live CD compiled with "set ROS_LEAN_AND_MEAN = yes"? If not, is it possible to compile it with this flag? For other purposes beside the normal user testing, we have the SVN DEB Live CD image.

Do you even know what you're doing? I've seen many commits where you call something a FIX and then just comment code out and add another FIXME.... dgorbachev(a)svn.reactos.org wrote: > Author: dgorbachev > Date: Sun Jun 10 15:11:05 2007 > New Revision: 27107 > > URL: http://svn.reactos.org/svn/reactos?rev=27107&view=rev > Log: > Fix issue #2151. > > Modified: > trunk/reactos/ntoskrnl/mm/sysldr.c > > Modified: trunk/reactos/ntoskrnl/mm/sysldr.c > URL: http://svn.reactos.org/svn/reactos/trunk/reactos/ntoskrnl/mm/sysldr.c?rev=2… > ============================================================================== > --- trunk/reactos/ntoskrnl/mm/sysldr.c (original) > +++ trunk/reactos/ntoskrnl/mm/sysldr.c Sun Jun 10 15:11:05 2007 > @@ -1767,7 +1767,7 @@ > NtHeader->OptionalHeader.AddressOfEntryPoint); > LdrEntry->SizeOfImage = DriverSize; > LdrEntry->CheckSum = NtHeader->OptionalHeader.CheckSum; > - LdrEntry->SectionPointer = LdrEntry; > + LdrEntry->SectionPointer = NULL; // ? > > /* Now write the DLL name */ > LdrEntry->BaseDllName.Buffer = (PVOID)(LdrEntry + 1); > > >

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

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 06 Jun '07

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.

Re: [ros-dev] [ros-diffs] [dgorbachev] 26893: Do not free the string twice.
by Aleksey Bragin 25 May '07

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 23 May '07

23 May '07

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.
