user/sven/git.git/path.c, branch v1.5.4.4

Add is_absolute_path() and make_absolute_path()

2007-08-01T07:38:30Z

This patch adds convenience functions to work with absolute paths. The function is_absolute_path() should help the efforts to integrate the MinGW fork. Note that make_absolute_path() returns a pointer to a static buffer. Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano

git_mkstemp(): be careful not to overflow the path buffer.

2007-07-26T04:34:53Z

If user's TMPDIR is insanely long, return negative after setting errno to ENAMETOOLONG, pretending that the underlying mkstemp() choked on a temporary file path that is too long. Signed-off-by: Junio C Hamano

getenv/setenv: use constants if available

2007-07-02T08:33:44Z

There were places using "GIT_DIR" instead of GIT_DIR_ENVIRONMENT and "GIT_CONFIG" instead of CONFIG_ENVIRONMENT. This makes it easier to find all places touching an environment variable using git grep or similar tools. Signed-off-by: Matthias Lederhofer Signed-off-by: Junio C Hamano

General const correctness fixes

2007-03-07T18:47:10Z

We shouldn't attempt to assign constant strings into char*, as the string is not writable at runtime. Likewise we should always be treating unsigned values as unsigned values, not as signed values. Most of these are very straightforward. The only exception is the (unnecessary) xstrdup/free in builtin-branch.c for the detached head case. Since this is a user-level interactive type program and that particular code path is executed no more than once, I feel that the extra xstrdup call is well worth the easy elimination of this warning.

Merge branch 'jc/detached-head'

2007-01-12T00:47:34Z

* jc/detached-head: git-checkout: handle local changes sanely when detaching HEAD git-checkout: safety check for detached HEAD checks existing refs git-checkout: fix branch name output from the command git-checkout: safety when coming back from the detached HEAD state. git-checkout: rewording comments regarding detached HEAD. git-checkout: do not warn detaching HEAD when it is already detached. Detached HEAD (experimental) git-branch: show detached HEAD git-status: show detached HEAD

short i/o: fix calls to read to use xread or read_in_full

2007-01-08T23:44:47Z

We have a number of badly checked read() calls. Often we are expecting read() to read exactly the size we requested or fail, this fails to handle interrupts or short reads. Add a read_in_full() providing those semantics. Otherwise we at a minimum need to check for EINTR and EAGAIN, where this is appropriate use xread().

Detached HEAD (experimental)

2007-01-08T11:02:11Z

This allows "git checkout v1.4.3" to dissociate the HEAD of repository from any branch. After this point, "git branch" starts reporting that you are not on any branch. You can go back to an existing branch by saying "git checkout master", for example. This is still experimental. While I think it makes sense to allow commits on top of detached HEAD, it is rather dangerous unless you are careful in the current form. Next "git checkout master" will obviously lose what you have done, so we might want to require "git checkout -f" out of a detached HEAD if we find that the HEAD commit is not an ancestor of any other branches. There is no such safety valve implemented right now. On the other hand, the reason the user did not start the ad-hoc work on a new branch with "git checkout -b" was probably because the work was of a throw-away nature, so the convenience of not having that safety valve might be even better. The user, after accumulating some commits on top of a detached HEAD, can always create a new branch with "git checkout -b" not to lose useful work done while the HEAD was detached. We'll see.

simplify inclusion of system header files.

2006-12-20T17:51:35Z

This is a mechanical clean-up of the way *.c files include system header files. (1) sources under compat/, platform sha-1 implementations, and xdelta code are exempt from the following rules; (2) the first #include must be "git-compat-util.h" or one of our own header file that includes it first (e.g. config.h, builtin.h, pkt-line.h); (3) system headers that are included in "git-compat-util.h" need not be included in individual C source files. (4) "git-compat-util.h" does not have to include subsystem specific header files (e.g. expat.h). Signed-off-by: Junio C Hamano

adjust_shared_perm: chmod() only when needed.

2006-11-06T02:36:36Z

When widening permission for files and directories in a 'shared' repository for a user with inappropriate umask() setting for shared work, make sure we call chmod() only when we actually need to. The primary idea owes credit to Johannes. Signed-off-by: Junio C Hamano

Allow multiple "git_path()" uses

2006-09-16T09:21:11Z

This allows you to maintain a few filesystem pathnames concurrently, by simply replacing the single static "pathname" buffer with a LRU of four buffers. We did exactly the same thing with sha1_to_hex(), for pretty much exactly the same reason. Sometimes you want to use two pathnames, and while it's easy enough to xstrdup() them, why not just do the LU buffer thing. Signed-off-by: Linus Torvalds Signed-off-by: Junio C Hamano
