2010-10-03Add MinGW-specific execv() override.Eric Sunshine
As of 2dbc887e, shell.c employs execv(), so provide a MinGW-specific mingw_execv() override, complementing existing mingw_execvp() and cousins. As a bonus, this also resolves a compilation warning due to an execv() prototype mismatch between Linux and MinGW. Linux expects the second argument to be (char *const *), whereas MinGW expects (const char *const *).

2010-10-03mingw: do not crash on open(NULL, ...)Erik Faye-Lund
fetch_and_setup_pack_index() apparently pass a NULL-pointer to parse_pack_index(), which in turn pass it to check_packed_git_idx(), which again pass it to open(). Since open() already sets errno correctly for the NULL-case, let's just avoid the problematic strcmp.

2010-10-01MinGW: fix stat() and lstat() implementations for handling symlinksPat Thoyts
In msysGit the stat() function has been implemented using mingw_lstat which sets the st_mode member to S_IFLNK when a symbolic links is found. This causes the is_executable function to return when git attempts to build a list of available commands in the help code and we end up missing most git commands. (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. Includes squashed fix st_mode for symlink dirs Signed-off-by: Pat Thoyts <patthoyts@users.sourceforge.net> Signed-off-by: Erik Faye-Lund <kusmabite@gmail.com>

2010-08-26Fix compat/regex ANSIfication on MinGWJohannes Sixt
compat/regexec.c had a weird combination of function declaration in ANSI style and function definition in K&R style, for example: static unsigned re_copy_regs (struct re_registers *regs, regmatch_t *pmatch, int nregs, int regs_allocated) internal_function; static unsigned re_copy_regs (regs, pmatch, nregs, regs_allocated) struct re_registers *regs; regmatch_t *pmatch; int nregs, regs_allocated; { ... } with this #define: #ifndef _LIBC # ifdef __i386__ # define internal_function __attribute ((regparm (3), stdcall)) # else # define internal_function # endif #endif The original version as shown above was fine, but with the ANSIfied function definition and in the case where internal_function is not empty, gcc identifies the declaration and definition as different and bails out. Adding internal_function to the definition doesn't help (it results in a syntax error); hence, remove it from the subset of declarations that gcc flags as erroneous.

2010-05-20Fix checkout of large files to network shares on Windows XPRené Scharfe
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. There's still room for some other version of Windows to use a chunk size of 1MB without increasing the number of system calls.

2010-03-31Don't redefine htonl and ntohl on big-endianHolger Weiß
Since commit 0fcabdeb52b79775173d009ccc179db104dfbb66, compat/bswap.h redefined htonl and ntohl to bswap32 not only if bswap32 has been defined earlier in compat/bswap.h (which is done only on selected platforms), but also if bswap32 has been defined anywhere else. This broke Git at least for NetBSD systems running on big-endian machines (where ntohl and htonl should, of course, be NOOPs), since NetBSD defines a bswap32 macro in the system headers. So, we now undefine any previously defined bswap32 in compat/bswap.h before defining our own. Signed-off-by: Holger Weiß <holger@zedat.fu-berlin.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Having recently added support for building git-imap-send on Windows, we now link against OpenSSL libraries, and the linker issues the following warning: warning LNK4044: unrecognized option '/lssl'; ignored In order to suppress the warning, we change the msvc linker script to translate an '-lssl' parameter to the ssleay32.lib library. Note that the linker script was already including ssleay32.lib (along with libeay32.lib) as part of the translation of the '-lcrypto' library parameter. However, libeay32.dll does not depend on ssleay32.dll and can be used stand-alone, so we remove ssleay32.lib from the '-lcrypto' translation. The dependence of ssleay32.dll on libeay32.dll is represented in the Makefile by the NEEDS_CRYPTO_WITH_SSL build variable. Also, add the corresponding change to the buildsystem generator.
