René Scharfe	679eebe24d	abspath: convert absolute_path() to strbuf Move most of the code of absolute_path() into the new function strbuf_add_absolute_path() and in the process transform it to use struct strbuf and xgetcwd() instead of a PATH_MAX-sized buffer, which can be too small on some file systems.

Antoine Pelisse	fc2b621454	Prevent buffer overflows when path is too long Some buffers created with PATH_MAX length are not checked when being written, and can overflow if PATH_MAX is not big enough to hold the path. Replace those buffers by strbufs so that their size is automatically grown if necessary. They are created as static local variables to avoid reallocating memory on each call. Note that prefix_filename() returns this static buffer so each callers should copy or use the string immediately (this is currently true).

Jonathan Nieder	380395d094	mingw: rename WIN32 cpp macro to GIT_WINDOWS_NATIVE Throughout git, it is assumed that the WIN32 preprocessor symbol is defined on native Windows setups (mingw and msvc) and not on Cygwin. On Cygwin, most of the time git can pretend this is just another Unix machine, and Windows-specific magic is generally counterproductive. Unfortunately Cygwin does define the WIN32 symbol in some headers. Best to rely on a new git-specific symbol GIT_WINDOWS_NATIVE instead, defined as follows: #if defined(WIN32) && !defined(__CYGWIN__) # define GIT_WINDOWS_NATIVE #endif After this change, it should be possible to drop the CYGWIN_V15_WIN32API setting without any negative effect.

Michael Haggerty	f4c21e89d7	real_path(): properly handle nonexistent top-level paths The change has two points: 1. Do not strip off a leading slash, because that erroneously turns an absolute path into a relative path. 2. Do not remove slashes from groups of multiple slashes; instead let chdir() handle them. It could be, for example, that it wants to leave leading double-slashes alone. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>	13 years ago

Dmitry Ivankov	0687628466	Reduce parse-options.o dependencies Currently parse-options.o pulls quite a big bunch of dependencies. his complicates it's usage in contrib/ because it pulls external dependencies and it also increases executables size. Split off less generic and more internal to git part of parse-options.c to parse-options-cb.c. Move prefix_filename function from setup.c to abspath.c. abspath.o and wrapper.o pull each other, so it's unlikely to increase the dependencies. It was a dependency of parse-options.o that pulled many others. Now parse-options.o pulls just abspath.o, ctype.o, strbuf.o, usage.o, wrapper.o, libc directly and strlcpy.o indirectly.

Johannes Schindelin	7d092adc8f	get_pwd_cwd(): Do not trust st_dev/st_ino blindly `10c4c88` (Allow add_path() to add non-existent directories to the path, 2008-07-21) introduced get_pwd_cwd() function in order to favor $PWD when getenv("PWD") and getcwd() refer to the same directory but are different strings (e.g. the former gives a nicer looking name via a symbolic link to an uglier looking automounted path). The function tried to determine if two directories are the same by running stat(2) on both and comparing ino/dev fields. Unfortunately, stat() does not fill any ino or dev fields in msysgit. But there is a telltale: both ino and dev are 0 when they are not filled correctly, so let's be extra cautious. This happens to fix a bug in "get-receive-pack working_directory/" when the GIT_DIR would not be set correctly due to absolute_path(".") returning the wrong value.

Theo Niessink	d1c69255a1	real_path: do not assume '/' is the path seperator real_path currently assumes it's input had '/' as path seperator. This assumption does not hold true for the code-path from prefix_path (on Windows), where real_path can be called before normalize_path_copy. Fix real_path so it doesn't make this assumption. Create a helper function to reverse-search for the last path-seperator in a string.

Carlos Martín Nieto	e2a57aac8a	Name make__path functions more accurately Rename the make__path functions so it's clearer what they do, in particlar make clear what the differnce between make_absolute_path and make_nonrelative_path is by renaming them real_path and absolute_path respectively. make_relative_path has an understandable name and is renamed to relative_path to maintain the name convention. The function calls have been replaced 1-to-1 in their usage. Signed-off-by: Carlos Martín Nieto <cmn@elego.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>	14 years ago
Carlos Martín Nieto	1d679de58e	make_absolute_path: return the input path if it points to our buffer Some codepaths call make_absolute_path with its own return value as input.

Eric Sunshine	b248e95096	Fix 'clone' failure at DOS root directory. 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).

Nguyễn Thái Ngọc Duy	ed0cb46ebb	make_absolute_path(): Do not append redundant slash When concatenating two paths, if the first one already have '/', do not put another '/' in between the two paths. Usually this is not the case as getcwd() won't return '/foo/bar/', except when you are standing at root, then it will return '/'.

Brandon Casey	1630726e84	abspath.c: move declaration of 'len' into inner block and use appropriate type The 'len' variable was declared at the beginning of the make_absolute_path function and also in an inner 'if' block which masked the outer declaration. It is only used in two 'if' blocks, so remove the outer declaration and make a new declaration inside the other 'if' block that uses 'len'.

Johannes Sixt	10c4c881c4	Allow add_path() to add non-existent directories to the path This function had used make_absolute_path(); but this function dies if the directory that contains the entry whose relative path was supplied in the argument does not exist. This is a problem if the argument is, for example, "../libexec/git-core", and that "../libexec" does not exist. Since the resolution of symbolic links is not required for elements in PATH, we can fall back to using make_nonrelative_path(), which simply prepends $PWD to the path. We have to move make_nonrelative_path() alongside make_absolute_path() in abspath.c so that git-shell can be linked. See `5b8e6f85f`.

Dmitry Potapov	5b8e6f85f9	shrink git-shell by avoiding redundant dependencies A lot of modules that have nothing to do with git-shell functionality were linked in, bloating git-shell more than 8 times. This patch cuts off redundant dependencies by: 1. providing stubs for three functions that make no sense for git-shell; 2. moving quote_path_fully from environment.c to quote.c to make the later self sufficient; 3. moving make_absolute_path into a new separate file.
