2012-08-08Merge branch 'bw/maint-1.7.9-solaris-getpass'Libravatar Junio C Hamano1-0/+1
The recent update to terminal I/O interface to get passwords &c interactively didn't quite work on Solaris. * bw/maint-1.7.9-solaris-getpass: Enable HAVE_DEV_TTY for Solaris terminal: seek when switching between reading and writing
2012-08-06terminal: seek when switching between reading and writingLibravatar Jeff King1-0/+1
When a stdio stream is opened in update mode (e.g., "w+"), the C standard forbids switching between reading or writing without an intervening positioning function. Many implementations are lenient about this, but Solaris libc will flush the recently-read contents to the output buffer. In this instance, that meant writing the non-echoed password that the user just typed to the terminal. Fix it by inserting a no-op fseek between the read and write. The opposite direction (writing followed by reading) is also disallowed, but our intervening fflush is an acceptable positioning function for that alternative.

2012-07-13Merge branch 'tb/sanitize-decomposed-utf-8-pathname'Libravatar Junio C Hamano2-0/+235
Teaches git to normalize pathnames read from readdir(3) and all arguments from the command line into precomposed UTF-8 (assuming that they come as decomposed UTF-8) to work around issues on Mac OS. I think there still are other places that need conversion (e.g. paths that are read from stdin for some commands), but this should be a good first step in the right direction. * tb/sanitize-decomposed-utf-8-pathname: git on Mac OS and precomposed unicode
2012-07-08git on Mac OS and precomposed unicodeLibravatar Torsten Bögershausen2-0/+235
Mac OS X mangles file names containing unicode on file systems HFS+, VFAT or SAMBA. When a file using unicode code points outside ASCII is created on a HFS+ drive, the file name is converted into decomposed unicode and written to disk. No conversion is done if the file name is already decomposed unicode. Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same result as open("\x41\xcc\x88",...) with a decomposed "Ä". As a consequence, readdir() returns the file names in decomposed unicode, even if the user expects precomposed unicode. Unlike on HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in precomposed unicode, but readdir() still returns file names in decomposed unicode. When a git repository is stored on a network share using SAMBA, file names are send over the wire and written to disk on the remote system in precomposed unicode, but Mac OS X readdir() returns decomposed unicode to be compatible with its behaviour on HFS+ and VFAT. The unicode decomposition causes many problems: - The names "git add" and other commands get from the end user may often be precomposed form (the decomposed form is not easily input from the keyboard), but when the commands read from the filesystem to see what it is going to update the index with already is on the filesystem, readdir() will give decomposed form, which is different. - Similarly "git log", "git mv" and all other commands that need to compare pathnames found on the command line (often but not always precomposed form; a command line input resulting from globbing may be in decomposed) with pathnames found in the tree objects (should be precomposed form to be compatible with other systems and for consistency in general). - The same for names stored in the index, which should be precomposed, that may need to be compared with the names read from readdir(). NFS mounted from Linux is fully transparent and does not suffer from the above. As Mac OS X treats precomposed and decomposed file names as equal, we can - wrap readdir() on Mac OS X to return the precomposed form, and - normalize decomposed form given from the command line also to the precomposed form, to ensure that all pathnames used in Git are always in the precomposed form. This behaviour can be requested by setting "core.precomposedunicode" configuration variable to true. The code in compat/precomposed_utf8.c implements basically 4 new functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(), precomposed_utf8_closedir() and precompose_argv(). The first three are to wrap opendir(3), readdir(3), and closedir(3) functions. The argv[] conversion allows to use the TAB filename completion done by the shell on command line. It tolerates other tools which use readdir() to feed decomposed file names into git. When creating a new git repository with "git init" or "git clone", "core.precomposedunicode" will be set "false". The user needs to activate this feature manually. She typically sets core.precomposedunicode to "true" on HFS and VFAT, or file systems mounted via SAMBA.

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 Jones2-4/+6
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.

2011-12-12add generic terminal prompt functionLibravatar Jeff King2-0/+87
When we need to prompt the user for input interactively, we want to access their terminal directly. We can't rely on stdio because it may be connected to pipes or files, rather than the terminal. Instead, we use "getpass()", because it abstracts the idea of prompting and reading from the terminal. However, it has some problems: 1. It never echoes the typed characters, which makes it OK for passwords but annoying for other input (like usernames). 2. Some implementations of getpass() have an extremely small input buffer (e.g., Solaris 8 is reported to support only 8 characters). 3. Some implementations of getpass() will fall back to reading from stdin (e.g., glibc). We explicitly don't want this, because our stdin may be connected to a pipe speaking a particular protocol, and reading will disrupt the protocol flow (e.g., the remote-curl helper). 4. Some implementations of getpass() turn off signals, so that hitting "^C" on the terminal does not break out of the password prompt. This can be a mild annoyance. Instead, let's provide an abstract "git_terminal_prompt" function that addresses these concerns. This patch includes an implementation based on /dev/tty, enabled by setting HAVE_DEV_TTY. The fallback is to use getpass() as before. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-12-12compat/snprintf: don't look at va_list twiceLibravatar Jeff King1-2/+7
If you define SNPRINTF_RETURNS_BOGUS, we use a special git_vsnprintf wrapper assumes that vsnprintf returns "-1" instead of the number of characters that you would need to store the result. To do this, it invokes vsnprintf multiple times, growing a heap buffer until we have enough space to hold the result. However, this means we evaluate the va_list parameter multiple times, which is generally a bad thing (it may be modified by calls to vsnprintf, yielding undefined behavior). Instead, we must va_copy it and hand the copy to vsnprintf, so we always have a pristine va_list. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-06-16t1301-*.sh: Fix the 'forced modes' test on cygwinLibravatar Ramsay Jones1-2/+1
The 'forced modes' test fails on cygwin because the post-update hook loses it's executable bit when copied from the templates directory by git-init. The template loses it's executable bit because the lstat() function resolves to the "native Win32 API" implementation. This call to lstat() happens after git-init has set the "git_dir" (so has_git_dir() returns true), but before the configuration has been fully initialised. At this point git_config() does not find any config files to parse and returns 0. Unfortunately, the code used to determine the cygwin l/stat() function bindings did not check the return from git_config() and assumed that the config was complete and accessible once "git_dir" was set. In order to fix the test, we simply change the binding code to test the return value from git_config(), to ensure that it actually had config values to read, before determining the requested binding.
