[RFC/PATCH 00/14] Build git with MSVC

[RFC/PATCH 00/14] Build git with MSVC

[Marius Storm-Olsen]

So, Frank Li started this series, and I took it upon my self to help
out a bit; cleaning, reorganizing, rebasing the series. Hopefully
we're now a bit closer to including the series into mainline..

Here's a summary of what has happend:
1) This series is rebased ontop of git.git 'next', which needed an
   extra patch to avoid a non-constant array creation, which
   mscv doesn't like.
2) I've polished (tied to anyways) the commit messages a bit.
3) I've applied much of the feedback provided to the first round of
   the patches.
4) I've split, merged and reordered some of the patches, so things
   that belong together are in the same commits, and in a order of
   'importance'
5) I've removed the
       #define func _func
   stuff, as it's not needed and Microsoft cannot really kill the
   compatibility functions anyways. So, adding the define
       _CRT_NONSTDC_NO_DEPRECATE
   will kill the warnings seen without the defines above.
6) ..probably much more as well, but I forget..

Note: I did not sign off on the last two commits, which involve the
adding of the vcproj files, since I don't agree on adding them as is.
We need a Makefile way of compiling primarily, and second, a script
to generate the vcproj, as already discussed. But the commits are
included for completeness, at to let others compile and play with it.

I've kept the original author as is, and just signed the patches..
Thanks for watching, now bring on the comments!

[PATCH 01/14] Fix non-constant array creation

[Marius Storm-Olsen]

MSVC doesn't munge the non-constant expression, so use xmalloc instead.

[PATCH 07/14] Fix __stdcall/WINAPI placement and function prototype

[Marius Storm-Olsen]

From: Frank Li <lznuaa@gmail.com>

WINAPI is a macro which translates into the proper calling convention, so
replace __stdcall with that.

MSVC requires WINAPI to be between the functions return value and the
function name, and that the function pointer type is in the form of
    return_type (WINAPI *function_name)(arguments...)

How about using alloca instead? It allocates from the stack (just like
the C99-style variable-length array you're replacing), and you don't
need to free the memory afterwards.

... or is alloca frowned upon? I see it's already used both in
compat/regex/regex.c and in compat/nedmalloc/malloc.c, but not
apparently not in the git core.

MSVC compiles regex.c, so it must handle it. I'm fine with that.

The true reason is MSVC type define errcode as int.

msvc supports alloca, but regex.c doesn't make use of it per default
(you must define HAVE_ALLOCA_H in order to use it). basically _alloca
is fine for that task, but be aware that error handling on windows is
a bit compilicated. when _alloca fails it throws a structured
exception, you must reset the stack and use traditional memory
allocation as fallback. see

These two are not nice. As I said in an earlier mail: The documentation says 
that the thread function pointer that is passed to _beginthreadex must have 
__stdcall calling convention. Therefore, you should not change these to 
WINAPI.

WINAPI is just a define for __stdcall (since _MSC_VER >= 800 anyways; VC 
6.0 being _MSC_VER == 1200), and won't change.

So, IMO the change is not bad, and makes things less convoluted by using 
the same convention all over.

(And _beginthreadex actually accepts both __stdcall and __clrcall 
calling conventions.)

I must admit that I didn't look much at the surrounding code to know how 
large preimage->nr can get. But assuming variable-length array is 
handled the same way by the compiler as alloca(), and this code seems to 
be performing fine, I guess it's safe to say that this code won't be 
triggering any SEH, and thus we won't need to handle it?

So, given my assumptions I think we can just replace that one line with 
alloca(), nuke the free(), and everything is ok.

alloca() throws an exception when out of stack memory. But what would

that those arrays are also created on the stack, which I don't know...) 
Is that realy more complicated?

[PATCH v2 05/14] Change regerror() definition from K&R style to ANSI C (C89)

[Marius Storm-Olsen]

From: Frank Li <lznuaa@gmail.com>

The MSVC headers typedef errcode as int, and thus confused the
compiler in the K&R style definition. ANSI style deconfuses it.

Thanks.

These things are called variable length array, and MSVC is not the only
one that do not glok vla.

	Subject: Avoid use of variable length array

        Some compilers unfortunately do not understand these constructs.
	In codepaths that are not performance critical, use xmalloc()
        and free() instead.

There is another use of vla; I would suggest squashing the following patch

This contradicts the way I read the comment in compat/snprintf.c from
f4626df (Add target architecture MinGW., 2007-12-01).

As far as I can see, the correction is about the meaning of the size
parameter to the function, namely, that a broken implementation may
mistakenly think that it was told the maximum length of the meat of the
string to write, and it is allowed to append a NUL beyond the limit, when
the caller actually is telling it the size of the buffer.

So if my reading is correct, it is not about "does not add NUL at the end"
at all; it is "adds NUL beyond the end of given output buffer."

The first sentence sort-of makes sense; compat/msvc.h will be included by
git-compat-util.h and including <windows.h> here will bring conflicting
definitions, so we avoid doing so when on MSC.

The second sentence does not make any sense to me.  It may be correctly
stating a fact (i.e. "defines required WAPI version"), but it is unclear 
what relevance it has to this change to stop including <windows.h>.

Having said that, the first sentence hints me that perhaps you guys should
include (conditionally only on windows but not with MSC) <windows.h> not
from this file, but from git-compat-util.h?

The way things are configured, windows.h is pulling in winsock.h. In
git-compat-util.h, winsock2.h is included which has conflicting
definitions of various functions and data structures.

> Having said that, the first sentence hints me that perhaps you guys should

It would make sense for windows.h to be included in git-compat-util.h.

According to http://social.msdn.microsoft.com/Forums/en-US/windowssdk/thread/4a90b143-1fb8-43e9-a54c-956127e0c579,
the following will work:

#define _WINSOCKAPI_    // stops windows.h including winsock.h
#include <winsock2.h>
#include <windows.h>

Also, if you define WIN32_LEAN_AND_MEAN, windows.h will pull in a
subset of the Windows header files (which also improves compilation
times). Adding this may prevent it from pulling in winsock.h. This
would be a better approach (and would make sense to go into
git-compat-util.h).

I don't have access to a Windows dev box at the moment, so can't
verify that this does indeed work.

As far as I know, the windows implementation does not add a terminating 
NUL when the string to write is greater or equal to the given buffer 
size. Otherwise it does add the NUL.
Same as for strncpy() on windows.
In my experience the windows implementation does never write behind the 
given buffer, not even a terminating zero.

Not quite. The parameter *is* the size of the buffer and vsnprintf does not 
write beyond the buffer. However, it has the awkward behavior that if the 
buffer is too short by exactly one byte, i.e. there is room for the complete 
string, but not for the terminating NUL, then vsnprintf does not report an 
error!

Therefore, we tell vsnprintf that the buffer is shorter by one byte and always 
write NUL in the last position so that we get a correctly terminated string 
even in this case.

You get a run-time error. Or rather, you get a run-time error if
you're out of address space. If you go out of memory, swapping
mechanisms are used. And in turn, if the swapping mechanisms fail,
you'll get a run-time error AFAIK.

IIRC, Visual Studio can be configured to use different keyboard shortcuts.

However, saying "press F7" says nothing of the intent. It would
probably be better to have this say something like "Then build the
solution." or "Open gitbuild\gitbuild.sln with Visual Studio 2008,
then build it." But then you don't need to open Visual Studio 2008 to
build it (you can build it from command line).

So, how about:

The easiest is just do the following on the command line, provided 
that you have the msysgit environment available (so GNU Make etc):
     make common-cmds.h

That will ensure that the file is generated correctly. After that you 
can build with msvc, based on the patch series.

Since the real reason isn't the K&R style defintion, but that
"errcode" has been typedef'ed, perhaps it's better to either do
something like this:

#ifdef _MSC_VER
#define errcode dummy_def
#include <crtdefs.h>
#undef errcode

...before the first crt-inclusion, or simply to rename "errcode" to
something like "error"? The latter can be done with the preprocessor
after the first crt-inclusion.

Is this correct?  All the others entries are configured like this:
[submodule ext/git]
      path = ext/git
      url = git://repo.or.cz/tgit.git

Another question: Is not better to put the README inside gitbuild with
the other files instead of compat/vcbuild/?

Thanks!

Now when I run 'git submodule update' I recieve this error:
'fatal: Needed a single revision
Unable to find the current revision in submodule path 'ext/OpenSSL''

If the output of 'git submodule status' help, this is:
 fdd0f73b9a3e7c1fdf15c2e2a52582c637ec96f1 ext/OpenSSL

Re: [PATCH 08/14] Test for WIN32 instead of __MINGW32_

[Paolo Bonzini]

Since you are doing this, you may as well change patch 3 from

+#if (defined(__MINGW32__) && defined(__GNUC__) && __GNUC__ < 4) || 
defined(_MSC_VER)

to this:

#if defined WIN32 && (!defined (__GNUC__) || __GNUC__ < 4))

I just gave this script a try, but if I simply click the .bat-file, I
get the following crash in sh.exe: "Unhandled exception at 0x77ba8e7c
in sh.exe: 0xC0000005: Access violation writing location 0x00000014."

Here's the output I get on the console:

Since the path is set to only point to the tools, my guess is that
other msys installations (I've got two) shouldn't affect this, no?

I'm running Vista 64bit.
