2013-06-02Merge branch 'fc/macos-x-clipped-write'Libravatar Junio C Hamano1-0/+1
Mac OS X does not like to write(2) more than INT_MAX number of bytes. * fc/macos-x-clipped-write: compate/clipped-write.c: large write(2) fails on Mac OS X/XNU
2013-05-17compate/clipped-write.c: large write(2) fails on Mac OS X/XNULibravatar Filipe Cabecinhas1-0/+1
Due to a bug in the Darwin kernel, write(2) calls have a maximum size of INT_MAX bytes. Introduce a new compat function, clipped_write(), that only writes at most INT_MAX bytes and returns the number of bytes written, as a substitute for write(2), and allow platforms that need this to enable it from the build mechanism with NEEDS_CLIPPED_WRITE. Set it for Mac OS X by default. It may be necessary to include this function on Windows, too. Signed-off-by: Filipe Cabecinhas <filcab+git@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-04-16convert: The native line-ending is \r\n on MinGWLibravatar Jonathan Nieder1-0/+1
If you try this: 1. Install Git for Windows (from the msysgit project) 2. Put [core] autocrlf = false eol = native in your .gitconfig. 3. Clone a project with *.txt text in its .gitattributes. Then with current git, any text files checked out have LF line endings, instead of the expected CRLF.

2013-02-26Revert "compat: add strtok_r()"Libravatar Erik Faye-Lund1-2/+0
This reverts commit 78457bc0ccc1af8b9eb776a0b17986ebd50442bc. commit 28c5d9e ("vcs-svn: drop string_pool") previously removed the only call-site for strtok_r. So let's get rid of the compat implementation as well.

2013-02-25msvc: avoid collisions between "tags" and "TAGS"Libravatar Ramsay Jones1-0/+1
Commit 2f769195 ("MinGW: avoid collisions between "tags" and "TAGS", 28-09-2010) enabled MinGW to use an ETAGS file in order to avoid filename collisions on (Windows) case insensitive filesystems. In addition, this prevents 'make' from issuing several warning messages. When using the Makefile to perform an MSVC build, which is usually executed using MinGW tools, we can also benefit from this capability. In order to reap the above benefits, we set the ETAGS_TARGET build variable to ETAGS in the MSVC config block.

2013-02-25msvc: test-svn-fe: Fix linker "unresolved external" errorLibravatar Ramsay Jones1-1/+0
In particular, while linking test-svn-fe.exe, the linker complains that the external symbol _strtoull is unresolved. A call to this function was added in commit ddcc8c5b ("vcs-svn: skeleton of an svn delta parser", 25-12-2010). The NO_STRTOULL build variable attempts to provide support to old systems which can't even declare 'unsigned long long' variables, let alone provide the strtoll() or strtoull() functions. Setting this build variable does not provide an implementation of these functions. Rather, it simply allows the compat implementations of strto{i,u}max() to use strtol() and strtoul() instead. In order to fix the linker error on systems with NO_STRTOULL set, currently MSVC and OSF1, we can substitute a call to strtoumax(). However, we can easily provide support for the strtoull() and strtoll() functions on MSVC, since they are essentially already available as _strtoui64() and _strtoi64(). This allows us to remove NO_STRTOULL for MSVC. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Tested-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-02-25msvc: git-daemon: Fix linker "unresolved external" errorsLibravatar Ramsay Jones1-0/+2
In particular, while linking git-daemon.exe, the linker complains that the external symbols _inet_pton and _inet_ntop are unresolved. Commit a666b472 ("daemon: opt-out on features that require posix", 04-11-2010) addressed this problem for MinGW by configuring the use of the internal 'compat' versions of these function. Although the MSVC header <WS2tcpip.h> contains the prototypes for the inet_pton and inet_ntop functions, they are only visible for Windows API versions from 0x0600 (Windows Vista) or later. (In addition, on Windows XP, ws2_32.dll does not export these symbols). In order to fix the linker errors, we also configure the MSVC build to use the internal compat versions of these functions by setting the NO_INET_{PTON,NTOP} build variables.

2013-02-11Allow building with xmlparse.hLibravatar Matt Kraai1-0/+1
expat 1.1 and 1.2 provide xmlparse.h instead of expat.h. Include the former on systems that define the EXPAT_NEEDS_XMLPARSE_H variable and define that variable on QNX systems, which ship with expat 1.1.

2013-01-03Makefile: hoist uname autodetection to config.mak.unameLibravatar Jeff King1-0/+539
Our Makefile first sets up some sane per-platform defaults by looking at "uname", then modifies that according to the results of autoconf (if any), then modifies that according to the user's wishes in config.mak. For sub-Makefiles like Documentation/Makefile, the latter two are available, but the uname defaults are available only to the main Makefile. This hasn't been a problem so far, because the sub-Makefiles do not rely on any of those automatic settings to do their work. This patch puts the uname magic into its own file so it can be reused in other Makefiles, opening up the possibility of new knobs. Note that we leave one reference to uname in the top-level Makefile: if we are on Darwin, we must check the NO_FINK and NO_DARWIN_PORTS settings. But because we are combining uname settings with user-options, we must do so after all of the config is loaded. This is acceptable, as the resulting conditionals are about setting variables specific to the top-level Makefile (and if that ever changes, we can hoist them into a separate post-config include, too).
