* DONTMERGE compat/regex: make it compile with -Werror=int-to-pointer-castab/compat-regex-updateJunio C Hamano2017-05-121-4/+2
| | | | | | | | | | The change by 56a1a3ab ("Silence GCC's "cast of pointer to integer of a different size" warning", 2015-10-26) may need resurrecting; I do not think an unprotected #include <stdint.h> is the best way to do this, but for the purpose of places that needs further work, thishsould do.

* compat/regex: update the gawk regex engine from upstreamÆvar Arnfjörð Bjarmason2017-05-109-422/+1158
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the gawk regex engine from the upstream gawk.git as detailed in the README added in a previous change. This is from gawk.git's gawk-4.1.0-2558-gb2651a80 which is the same code as in the stable gawk-4.1.4 release, but with one trivial change on top added in commit 725d2f78 ("Add small regex fix. Add support directory.", 2016-12-22)[1] The two patches applied on top of the upstream engine are to, respectively: * Add a notice at the top of each file saying that this copy is maintained by the Git project. * Remove the dependency on gawk's verify.h. The library compiles as-is when this header file is present, but unfortunately it's under GPL v3, unlike the rest of the files which is under LGPL 2.1 or later. The changes made in commit a997bf423d ("compat/regex: get the gawk regex engine to compile within git", 2010-08-17) turned out to be redundant to achieving the same with defining a few flags to make the code itself do similar things. In addition the -DNO_MBSUPPORT flag is not needed, upstream removed the code that relied on that. It's possible that either -DHAVE_BTOWC or -D_GNU_SOURCE could cause some problems on non-GNU systems. The -DHAVE_BTOWC flag indicates that wchar.h has a btowc(3). This function is defined in POSIX.1-2001 & C99 and later. The -D_GNU_SOURCE flag is needed because the library itself does: #ifndef _LIBC #define __USE_GNU 1 #endif Which is subsequently picked up by GNU C library headers: In file included from compat/regex/regex_internal.h:32:0, from compat/regex/regex.c:76: /usr/include/stdio.h:316:6: error: unknown type name ‘_IO_cookie_io_functions_t’; did you mean ‘__fortify_function’? _IO_cookie_io_functions_t __io_funcs) __THROW __wur; ^~~~~~~~~~~~~~~~~~~~~~~~~ 1. http://git.savannah.gnu.org/cgit/gawk.git/commit/?id=725d2f78 Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* compat/regex: add a README with a maintenance guideÆvar Arnfjörð Bjarmason2017-05-081-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a README file to compat/regex describing how the copy of the gawk engine should be maintained. Since gawk's regex engine was originally imported in git.git in commit d18f76dccf ("compat/regex: use the regex engine from gawk for compat", 2010-08-17) the Git project has forked the upstream code. Most of the changes that have been made in that time have been made redundant by similar changes made upstream. Out of all the modifications made to it since then, which can be found via: $ git log --oneline d18f76dccf..v2.13.0-rc2 -- compat/regex/ These are the only real code changes that aren't made fully redundant by upstream patches: ce518bbd6c ("Fix compat/regex ANSIfication on MinGW", 2010-08-26) 5b62e6374a ("compat/regex/regexec.c: Fix some sparse warnings", 2013-04-27) d099b7173d ("Fix some sparse warnings", 2013-07-18) These look to me like they might be a non-issue due to subsequent changes, or perhaps aren't needed anymore due to compiler updates. In addition a few style & typo changes have been made in that time: ce9171cd63 ("compat/regex: fix spelling and grammar in comments", 2013-04-12) 749f763dbb ("typofix: in-code comments", 2013-07-22) c01499ef69 ("C: have space around && and || operators", 2013-10-16) Some of these could still be applied, but I don't see any point in doing so. These are typo & style nits, if anyone really cares that much they should send updates to gawk.git instead of making the re-merging of code into git.git harder over such trivial issues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When removing the hack for isatty(), we actually removed more than just an isatty() hack: we removed the hack where internal data structures of the MSVC runtime are modified in order to redirect stdout/stderr. Instead of using that hack (that does not work with newer versions of the runtime, anyway), we replaced it by reopening the respective file descriptors. What we forgot was to mark stderr as unbuffered again. Reported by Hannes Sixt. Fixed with Jeff Hostetler's assistance.

Add an implementation based on compat/qsort.c for platforms that lack a native standards-compliant qsort_s() (i.e. basically everyone). It doesn't perform the full range of possible checks: It uses size_t instead of rsize_t and doesn't check nmemb and size against RSIZE_MAX because we probably don't have the restricted size type defined. For the same reason it returns int instead of errno_t. Signed-off-by: Rene Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

MSYS2 and Cygwin emulate pseudo terminals via named pipes, meaning that isatty() returns 0. f7f90e0f4f (mingw: make isatty() recognize MSYS2's pseudo terminals (/dev/pty*), 2016-04-27) fixed this for MSYS2 terminals, but not for Cygwin. The named pipes that Cygwin and MSYS2 use are very similar. MSYS2 PTY pipes are called 'msys-*-pty*' and Cygwin uses 'cygwin-*-pty*'. This commit modifies the existing check to allow both MSYS2 and Cygwin PTY pipes to be identified as TTYs. Note that pagination is still broken when running Git for Windows from within Cygwin, as MSYS2's less.exe is spawned (and does not like to interact with Cygwin's PTY).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When determining whether a handle corresponds to a *real* Win32 Console (as opposed to, say, a character device such as /dev/null), we use the GetConsoleOutputBufferInfo() function as a tell-tale. However, that does not work for *input* handles associated with a console. Let's just use the GetConsoleMode() function for input handles, and since it does not work on output handles fall back to the previous method for those. This patch prepares for using is_console() instead of my previous misguided attempt in cbb3f3c9b1 (mingw: intercept isatty() to handle /dev/null as Git expects it, 2016-12-11) that broke everything on Windows.

* | mingw: intercept isatty() to handle /dev/null as Git expects itJohannes Schindelin2016-12-112-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When Git's source code calls isatty(), it really asks whether the respective file descriptor is connected to an interactive terminal. Windows' _isatty() function, however, determines whether the file descriptor is associated with a character device. And NUL, Windows' equivalent of /dev/null, is a character device. Which means that for years, Git mistakenly detected an associated interactive terminal when being run through the test suite, which almost always redirects stdin, stdout and stderr to /dev/null. This bug only became obvious, and painfully so, when the new bisect--helper entered the `pu` branch and made the automatic build & test time out because t6030 was waiting for an answer.

When the process spawns a subprocess after obtaining the file descriptor, and if the subprocess has not exited when the attempt to remove or rename is made, the last step fails on Windows, because the subprocess has the file descriptor still open. Open tempfile with O_CLOEXEC flag to avoid this (on Windows, this is mapped to O_NOINHERIT). * bw/mingw-avoid-inheriting-fd-to-lockfile: mingw: ensure temporary file handles are not inherited by child processes t6026-merge-attr: child processes must not inherit index.lock handles

The symptom: Rename from 'xxx/.git/index.lock' to 'xxx/.git/index' failed. Should I try again? (y/n) Spawning child processes with bInheritHandles==FALSE would not work because no file handles would be inherited, not even the hStdXxx handles in STARTUPINFO (stdin/stdout/stderr). Opening every file with O_NOINHERIT does not work, either, as e.g. git-upload-pack expects inherited file handles. This leaves us with the only way out: creating temp files with the O_NOINHERIT flag. This flag is Windows-specific, however. For our purposes, it is equivalent to O_CLOEXEC (which does not exist on Windows), so let's just open temporary files with the O_CLOEXEC flag and map that flag to O_NOINHERIT on Windows. As Eric Wong pointed out, we need to be careful to handle the case where the Linux headers used to compile Git support O_CLOEXEC but the Linux kernel used to run Git does not: it returns an EINVAL. This fixes the test that we just introduced to demonstrate the problem.

However, gcc did not issue any such warning. After commit 56a1a3ab, in terms of the order of #includes and #defines, the code looked something like: $ cat -n junk.c 1 #include <stddef.h> 2 3 #define SIZE_MAX ((size_t) -1) 4 5 #include <stdint.h> 6 7 int main(int argc, char *argv[]) 8 { 9 return 0; 10 } $ $ gcc junk.c $ However, if you compile that file with -Wsystem-headers, then it will also issue a warning. Having set -Wsystem-headers in CFLAGS, using the config.mak file, then (on cygwin): $ make compat/regex/regex.o CC compat/regex/regex.o In file included from /usr/lib/gcc/x86_64-pc-cygwin/4.9.3/include/stdint.h:9:0, from compat/regex/regcomp.c:21, from compat/regex/regex.c:77: /usr/include/stdint.h:362:0: warning: "SIZE_MAX" redefined #define SIZE_MAX (__SIZE_MAX__) ^ In file included from compat/regex/regex.c:69:0: compat/regex/regex_internal.h:108:0: note: this is the location of the previous definition # define SIZE_MAX ((size_t) -1) ^ $ The compilation of the compat/regex code is somewhat unusual in that the regex.c file directly #includes the other c files (regcomp.c, regexec.c and regex_internal.c). Commit 56a1a3ab added an #include of <stdint.h> to the regcomp.c file, which results in the redefinition, since this is included after the regex_internal.h header. This header file contains a 'fallback' definition for SIZE_MAX, in order to support systems which do not have the <stdint.h> header (the HAVE_STDINT_H macro is not defined). In order to suppress the warning, we move the #include of <stdint.h> from regcomp.c to the start of the compilation unit, close to the top of regex.c, prior to the #include of the regex_internal.h header.

Therefore, some interactive functionality (such as launching a pager, asking if a failed unlink should be repeated etc.) doesn't work when run in a terminal emulator that uses MSYS2's ptys (such as mintty). However, MSYS2 uses special names for its pty pipes ('msys-*-pty*'), which allows us to distinguish them from normal piped input / output. On startup, check if stdin / stdout / stderr are connected to such pipes using the NtQueryObject API from NTDll.dll. If the names match, adjust the flags in MSVCRT's ioinfo structure accordingly.

However, this breaks building Git in Git for Windows' SDK because pthread_sigmask() is already a no-op there, #define'd in the pthread_signal.h header in /mingw64/x86_64-w64-mingw32/include/. Let's wrap the definition of pthread_sigmask() in a guard that skips it when compiling with MinGW-w64' headers.

Since there are no signal facilities on Windows that are similar to POSIX signals, just ignore the request to block the signal. In the particular case, the effect of blocking SIGPIPE on POSIX is that write() calls return EPIPE when the reader closes the pipe. This is how write() behaves on Windows.
