Re: [ros-dev] Autogenerating compiler specific .def files

by Aleksey Bragin

Theoretically extending this logic to infinity will lead to creation of a new high level language, stored in xml documents, parsing which rbuild generates source code in C or other language needed. :-). The thing is, .def is rather simple, .spec is a bit more advanced to include more stuff ("stub", what else does reactos use from it?). There is absolutely no need to invent yet another format for storing export functions. It was invented once by MSVC, it was invented by GCC/MinGW, both are incompatible, it was invented by Wine to have ability of easy functions stubbing. Should there be another invention of the same wheel by ReactOS now? If GCC/MinGW wouldn't be that *strange*, it could stdcall-fixup, and then properly link, this way .def could be created in the lowest common denominator format. With the best regards, Aleksey Bragin.

Autogenerating compiler specific .def files

by Marc Piulachs

Hi All, I have lately seen a big effort to make more modules compilable under Visual C , one of our current problems when building dlls is that our .def files are mingw/gcc specific not directly compatible with msvc or any other future compiler we may support. Currently we are using not very elegant solutions to archive compatibility with msvc like stripping some information from mingw def files. As Alex suggested I think it's a good idea to move that information to rbuild files and let rbuild generate full compatible compiler def files in the intermediate folder. The advantages are obvious. As I have little experience with mingw def files I would like to request some help from other developers to evaluate/validate my proposal. >From my research on the ros codebase I have found that possible variations: - CcRosInitializeFileCache@8 - FsRtlGetFileSize - @HalExamineMBR@16 - PsChargeProcessNonPagedPoolQuota@4=PsDereferenceImpersonationToken@4 - ConvertSecurityDescriptorToAccessNamedA=ConvertSecurityDescriptorToAccessA@2 8 - GetSecurityDescriptorLength(a)4=NTDLL.RtlLengthSecurityDescriptor - ??1type_info@@UAE@XZ=__thiscall_MSVCRT_type_info_dtor @15 - ChkdskEx=VfatChkdsk@24 My proposed syntax is as following and it should support all of the above cases: <exportfunction name="CcRosInitializeFileCache" ordinal="8" /> (required) (optional) <exportfunction name="CcRosInitializeFileCache" ordinal="8" mappedname="PsDereferenceImpersonationToken" mappedordinal="4"/> (required) (optional) (optional) (optional) <exportfunction name="GetSecurityDescriptorLength" ordinal="4" mappedname="RtlLengthSecurityDescriptor" mappedordinal="4" module="ntdll"/> (required) (optional) (optional) (optional) (optional) With this information rbuild will generate a modulename_gcc.def when you type "make" and modulename_msvc.def on the intermediate folder when you type "make msvc". Opinions, comments? Regards, Marc

Hi, why can't .spec be used for this purpose (extended to support msvc files generation)? They are going to stay anyway for wine-shared modules. With the best regards, Aleksey Bragin.

Re: [ros-dev] [ros-diffs] [cwittich] 30460: sync CryptAcquireContext to wine (this fixes some Unicode issues)

by Alex Ionescu

"HCRYPTHASH hPrivate; /*CSP's handle - Should not be given to application under any circumstances!*/" Are Wine people aware that DLLs load in the same address space as applications? There is no way to protect this handle from the application unless you store it in kernel-mode.

[ros-diffs] [weiden] 29670: Tweak the ScrollDC implementation a bit so that it produces a better output. The implementation still is completely incorrect as it should call the driver for this operation instead of doing a BitBlt operation...

NtGdiBitBlt calls IntEngBitBlt, wich calls DrvBitBlt if available. There's no DrvScroll function.

Re: [ros-dev] About UNICODE<->ASCII support.

by carlo.bramix

Hello, honestly, your enthusiasm seems a bit to exagerated to me! In the specific case, it looks like that all TCHARs in Taskmgr have been converted to WCHAR because the programme receives from the API some informations that are UNICODE only. I can understand and I agree to that, afterall it can be made working with unicows layer, if someone wants (and infact, I did it). Athough you should also admit that two WideCharToMultiByte() calls are not exactly something we can call "drammatic" code, which is automatically excluded by the presence of the magic UNICODE macro. I also agree with the fact that there could be the source code which interacts with UNICODE-only variables and the direct usage of WCHAR instead of TCHAR is very helpful and clean. But how many functions have this behavior (WCHAR-only)? It is not too difficult to count them and in my opinion this does not justify a refresh of sources for making TCHAR>WCHAR, or MessageBox>MessageBoxW... Last but not last... human beings can do errors, their changes may always introduce new errors, so more time for testing, etc... If I can do a suggestion, I would avoid unnecesary changes for this reason too. Afterall the binary code of the executable won't change by a single bit when TCHARs are converted to WCHARs at compile time, if there are not drawbacks like tons of conversions which will make the source code unreadable (it's also important that people understand the code for contribuiting). But if there are just TCHARs/_tcscpy/... I don't understand the reason.

Hi, welcome. The best is to join #reactos on freenode and have a live talk with devs. The language used throughout ReactOS is mostly C, with very few exceptions to C++. And if you have WinAPI knowledge, it would be appreciated. WBR, Aleksey Bragin. On Nov 14, 2007, at 12:16 AM, James Holland wrote: > My name is James Holland.

Introduction

by James Holland

My name is James Holland. I am interested in helping with the development of ReactOS. I am fairly adept with C++. I also have used APL (not very well) and MS Visual Basic at past times. I am currently using Java in my Computer Science class. For background, I am a Student at New Mexico Tech. My major is Electrical Engineering. I am open for any suggestions as to what I should do.
