2010-10-06do not depend on signed integer overflowLibravatar Erik Faye-Lund4-3/+15
Signed integer overflow is not defined in C, so do not depend on it. This fixes a problem with GCC 4.4.0 and -O3 where the optimizer would consider "consumed_bytes > consumed_bytes + bytes" as a constant expression, and never execute the die()-call.

2010-10-06work around buggy S_ISxxx(m) implementationsLibravatar René Scharfe1-3/+10
There are buggy implementations of S_ISxxx(m) macros on some platforms (e.g. NetBSD). The issue is that NetBSD doesn't take care to wrap its macro arguments in parentheses, so on Linux and sane systems we have S_ISREG(m) defined as something like: (((m) & S_IFMT) == S_IFREG) But on NetBSD: ((m & _S_IFMT) == _S_IFREG) Since a caller in builtin/diff.c called our macro as `S_IFREG | 0644' this bug introduced a logic error on NetBSD, since the precedence of bit-wise & is higher than | in C.

2010-10-06xdiff: cast arguments for ctype functions to unsigned charLibravatar Jonathan Nieder3-10/+11
The ctype functions isspace(), isalnum(), et al take an integer argument representing an unsigned character, or -1 for EOF. On platforms with a signed char, it is unsafe to pass a char to them without casting it to unsigned char first. Most of git is already shielded against this by the ctype implementation in git-compat-util.h, but xdiff, which uses libc ctype.h, ought to be fixed.

The buffer used to construct paths like ".git/objects/info" and ".git/objects/pack" is allocated on the heap and never freed. So free it. While at it, factor out the relevant code into its own function and rename the sha1_dir variable to object_directory (to match the change in everyday usage after the renaming of SHA1_FILE_DIRECTORY in v0.99~603^2~7, 2005).

2010-10-03setup: make sure git dir path is in a permanent bufferLibravatar Jonathan Nieder1-1/+3
If setup_git_env() is run before the usual repository discovery sequence and .git is a file with the text gitdir: <path> (with <path> any string) then the in-core git_dir variable is set to the result of converting <path> to an absolute path using make_absolute_path(). Unfortunately make_absolute_path() returns its result in a static buffer that is overwritten by later calls. Such a call could cause later accesses to git_dir (from git_pathdup(), for example) to read the wrong path, leaving git very confused. It is not obvious whether any existing code in git will trigger the problem, but in any case, it is worth a few dozen bytes to copy the return value from make_absolute_path() for some added peace of mind.

2010-10-03Add MinGW-specific execv() override.Libravatar Eric Sunshine2-0/+7
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 *).

2010-10-03Fix 'clone' failure at DOS root directory.Libravatar Eric Sunshine1-1/+5
Cloning via relative path fails for a project residing immediately under the root directory of a DOS drive. For instance, for project c:/foo, issuing "cd c:/" followed by "git clone foo bar" fails with error "Unable to find remote helper for 'c'". The problem is caused by make_nonrelative_path() incorrectly returning c://foo rather than c:/foo for input "foo". The bogus path c://foo is misinterpreted by transport_get() as a URL with unrecognized protocol "c", hence the missing remote helper error. Fix make_nonrelative_path() to return c:/foo rather than c://foo (and /foo rather than //foo on Unix).

2010-10-03Side-step MSYS-specific path "corruption" leading to t5560 failure.Libravatar Eric Sunshine1-2/+1
Upon program invocation, MSYS converts environment variables containing path-like values from Unix-style to DOS-style under the assumption that the program being invoked understands only DOS-style pathnames. For instance, the Unix-style path /msysgit is translated to c:/msysgit. For test t5560, the path being requested from git-http-backend is specified via environment variable PATH_INFO as a URL path of the form /repo.git/foobar, which git-http-backend combines with GIT_PROJECT_ROOT to determine the actual physical path within the repository. This is a case where MSYS's conversion of the path-like value of PATH_INFO causes harm, for two reasons. First, the resulting converted path, when joined with GIT_PROJECT_ROOT is bogus (for instance, "C:/msysgit/git/t/trash-zzz/C:/msysgit/repo.git/HEAD"). Second, the converted PATH_INFO path is rejected by git-http-backend as an 'alias' due to validation failure on the part of daemon_avoid_alias(). Unfortunately, the standard work-around of doubling the leading slash (i.e. //repo.git/foobar) to suppress MSYS path conversion works only for command-line arguments, but not for environment variables. Consequently, side step the problem by instead passing git-http-backend an already-constructed full path rather than components GIT_PROJECT_ROOT and PATH_INFO.

2010-10-03Side-step sed line-ending "corruption" leading to t6038 failure.Libravatar Eric Sunshine1-1/+3
By default, MSYS sed throws away CR from CRLF line-endings. Tests t6038.5 and t6038.6 employ sed to normalize conflict output of git-merge for validation purposes. These tests expect CRLF line-endings to be present in the normalized output of git-merge, and thus fail when sed undesirably removes CR. Fix by employing sed's -b/--binary switch to suppress its default behavior of dropping CR characters.

2010-10-01Skip t1300.70 and 71 on msysGit.Libravatar Pat Thoyts3-10/+6
These two tests fail on msysGit because /dev/null is an alias for nul on Windows and when reading the value back from git config the alias does not match the real filename. Also the HOME environment variable has a unix-style path but git returns a native equivalent path for '~'. As these are platform-dependent equivalent results it seems simplest to skip the test entirely. Moves the NOT_MINGW prereq from t5503 into the test library.

2010-10-01MinGW: fix stat() and lstat() implementations for handling symlinksLibravatar Pat Thoyts2-5/+37
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.
