2013-09-11MSVC: fix stat definition hellLibravatar Karsten Blees1-4/+11
In msvc.h, there's a couple of stat related functions defined diffently from mingw.h. When we remove these definitions, the only problem we get is "warning C4005: '_stati64' : macro redefinition" for this line in mingw.h: #define _stati64(x,y) mingw_stat(x,y) The reason is that as of MSVCR80.dll (distributed with MSVC 2005), the original _stati64 family of functions was renamed to _stat32i64, and the former function names became macros (pointing to the appropriate function based on the definition of _USE_32BIT_TIME_T). Defining _stati64 works on MinGW because MinGW by default compiles against the MSVCRT.DLL that is part of Windows (i.e. _stati64 is a function rather than a macro). Note: MinGW *can* compile for newer MSVC runtime versions, and MSVC apparently can also compile for the Windows MSVCRT.DLL via the DDK (see http://www.syndicateofideas.com/posts/fighting-the-msvcrt-dll-hell ). Remove the stat definitions from msvc.h, as they are not compiler related. In mingw.h, determine the runtime version in use from the definitions of _stati64 and _USE_32BIT_TIME_T, and define stat() accordingly. This also fixes that stat() in MSVC builds still resolves to mingw_lstat() instead of mingw_stat().

2013-04-28sparse: Fix mingw_main() argument number/type errorsLibravatar Ramsay Jones1-2/+2
Sparse issues 68 errors (two errors for each main() function) such as the following: SP git.c git.c:510:5: error: too many arguments for function mingw_main git.c:510:5: error: symbol 'mingw_main' redeclared with different type \ (originally declared at git.c:510) - different argument counts The errors are caused by the 'main' macro used by the MinGW build to provide a replacement main() function. The original main function is effectively renamed to 'mingw_main' and is called from the new main function. The replacement main is used to execute certain actions common to all git programs on MinGW (e.g. ensure the standard I/O streams are in binary mode). In order to suppress the errors, we change the macro to include the parameters in the declaration of the mingw_main function. Unfortunately, this change provokes both sparse and gcc to complain about 9 calls to mingw_main(), such as the following: CC git.o git.c: In function 'main': git.c:510: warning: passing argument 2 of 'mingw_main' from \ incompatible pointer type git.c:510: note: expected 'const char **' but argument is of \ type 'char **' In order to suppress these warnings, since both of the main functions need to be declared with the same prototype, we change the declaration of the 9 main functions, thus: int main(int argc, char **argv) Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Sparse issues the following warnings: SP compat/mingw.c compat/mingw.c:795:3: warning: symbol 'pinfo_t' was not declared. \ Should it be static? compat/mingw.c:796:16: warning: symbol 'pinfo' was not declared. \ Should it be static? compat/mingw.c:797:18: warning: symbol 'pinfo_cs' was not declared. \ Should it be static? compat/mingw.c:1207:23: warning: Using plain integer as NULL pointer In 'pinfo_t' variable, defined on line 795, seems to have been a mistake (a missing typedef keyword?), so we simply remove it. The 'pinfo' variable does not require more than file scope, so we simply add the static modifier to the declaration. The 'pinfo_cs' variable, in contrast, requires initialisation in the mingw replacement main() function, so we add an extern declaration to the compat/mingw.h header file. The remaining warning is suppressed by replacing the rhs of the pointer assignment with the NULL pointer literal.

2012-04-18compat/mingw.h: Set S_ISUID to prevent a fast-import test failureLibravatar Ramsay Jones1-3/+4
The current t9300-fast-import.sh test number 62 ("L: nested tree copy does not corrupt deltas") was introduced in commit 9a0edb79 ("fast-import: add a test for tree delta base corruption", 15-08-2011). A fix for the demonstrated problem was introduced by commit 8fb3ad76 ("fast-import: prevent producing bad delta", 15-08-2011). However, this fix didn't work on MinGW and so this test has always failed on MinGW. Part of the solution in commit 8fb3ad76 was to add an NO_DELTA preprocessor constant which was defined as follows: +/* + * We abuse the setuid bit on directories to mean "do not delta". + */ +#define NO_DELTA S_ISUID + Unfortunately, the S_ISUID constant on MinGW is defined as zero. In order to fix the problem, we simply alter the definition of S_ISUID in the mingw header file to a more appropriate value. Also, we take the opportunity to similarly define S_ISGID and S_ISVTX.

2012-04-05compat/mingw.[ch]: Change return type of exec functions to intLibravatar Ramsay Jones1-2/+2
The POSIX standard specifies a return type of int for all six exec functions. In addition, all exec functions return -1 on error, and simply do not return on success. However, the current emulation of the exec functions on mingw are declared with a void return type. This would cause a problem should any code attempt to call the exec function in a non-void context. In particular, if an exec function were used in a conditional it would fail to compile. In order to improve the fidelity of the emulation, we change the return type of the mingw_execv[p] functions to int and return -1 on error.

Even though Windows's socket functions look like their POSIX counter parts, they do not operate on file descriptors, but on "socket objects".

2010-11-23win32: use our own dirent.hLibravatar Erik Faye-Lund1-29/+0
The mingw-runtime implemenation of opendir, readdir and closedir sets errno to 0 on success, something that POSIX explicitly forbids. 3ba7a06 ("A loose object is not corrupt if it cannot be read due to EMFILE") introduce a dependency on this behaviour, leading to a broken "git clone" on Windows. compat/mingw.c contains an implementation of readdir, and compat/msvc.c contains implementations of opendir and closedir. Move these to compat/win32/dirent.[ch], and change to our own DIR structure at the same time. This provides a generic Win32-implementation of opendir, readdir and closedir which works on both MinGW and MSVC and does not reset errno, and as a result git clone is working again on Windows.

The Windows port have so far been using process handles in place of PID. However, this is not work consistent with what getpid returns. PIDs are system-global identifiers, but process handles are local to a process. Using PIDs instead of process handles allows, for instance, a user to kill a hung process with the Task Manager, something that would have been impossible with process handles. Change the code to use the real PID, and use OpenProcess to get a process-handle. Store the PID and the process handle in a linked list protected by a critical section, so we can safely close the process handle later. Linked list code written by Pat Thoyts.

(msysGit issue #445) This patch modifies the implementation so that lstat() will return the link flag but if we are called as stat() we read the size of the target and set the mode to that of a regular file.

Bigger writes to network drives on Windows XP fail. Cap them at 31MB to allow them to succeed. Callers need to be prepared for write() calls that do less work than requested anyway. On local drives, write() calls are translated to WriteFile() calls with a cap of 64KB on Windows XP and 256KB on Vista. Thus a cap of 31MB won't affect the number of WriteFile() calls which do the actual work.
