2011-03-17Name make_*_path functions more accuratelyCarlos Martín Nieto
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>
2011-03-16make_absolute_path: return the input path if it points to our bufferCarlos Martín Nieto
Some codepaths call make_absolute_path with its own return value as input. In such a cases, return the path immediately. This fixes a valgrind-discovered error, whereby we tried to copy a string onto itself. Signed-off-by: Carlos Martín Nieto <cmn@elego.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-10-03Fix 'clone' failure at DOS root directory.Eric Sunshine
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).

2010-02-14make_absolute_path(): Do not append redundant slashNguyễn Thái Ngọc Duy
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 '/'.

2009-08-27abspath.c: move declaration of 'len' into inner block and use appropriate typeBrandon Casey
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'.

2009-06-27Use die_errno() instead of die() when checking syscallsThomas Rast
Lots of die() calls did not actually report the kind of error, which can leave the user confused as to the real problem. Use die_errno() where we check a system/library call that sets errno on failure, or one of the following that wrap such calls: Function Passes on error from -------- -------------------- odb_pack_keep open read_ancestry fopen read_in_full xread strbuf_read xread strbuf_read_file open or strbuf_read_file strbuf_readlink readlink write_in_full xwrite Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>

A simple "grep -e stat --and -e S_ISDIR" revealed there are many open-coded implementations of this function. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-07-26Allow add_path() to add non-existent directories to the pathJohannes Sixt
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.

2008-06-28shrink git-shell by avoiding redundant dependenciesDmitry Potapov
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.
