Use git config file for committer name and email info

2005-10-12T01:47:34Z

This starts using the "user.name" and "user.email" config variables if they exist as the default name and email when committing. This means that you don't have to use the GIT_COMMITTER_EMAIL environment variable to override your email - you can just edit the config file instead. The patch looks bigger than it is because it makes the default name and email information non-static and renames it appropriately. And it moves the common git environment variables into a new library file, so that you can link against libgit.a and get the git environment without having to link in zlib and libcrypt. In short, most of it is renaming and moving, the real change core is just a few new lines in "git_default_config()" that copies the user config values to the new base. It also changes "git-var -l" to list the config variables. Signed-off-by: Linus Torvalds Signed-off-by: Junio C Hamano

Use core.filemode.

2005-10-12T01:45:33Z

With "[core] filemode = false", you can tell git to ignore differences in the working tree file only in executable bit. * "git-update-index --refresh" does not say "needs update" if index entry and working tree file differs only in executable bit. * "git-update-index" on an existing path takes executable bit from the existing index entry, if the path and index entry are both regular files. * "git-diff-files" and "git-diff-index" without --cached flag pretend the path on the filesystem has the same executable bit as the existing index entry, if the path and index entry are both regular files. If you are on a filesystem with unreliable mode bits, you may need to force the executable bit after registering the path in the index. * "git-update-index --chmod=+x foo" flips the executable bit of the index file entry for path "foo" on. Use "--chmod=-x" to flip it off. Note that --chmod only works in index file and does not look at nor update the working tree. So if you are on a filesystem and do not have working executable bit, you would do: 1. set the appropriate .git/config option; 2. "git-update-index --add new-file.c" 3. "git-ls-files --stage new-file.c" to see if it has the desired mode bits. If not, e.g. to drop executable bit picked up from the filesystem, say "git-update-index --chmod=-x new-file.c".

Add ".git/config" file parser

2005-10-10T23:31:08Z

This is a first cut at a very simple parser for a git config file. The format of the file is a simple ini-file like thing, with simple variable/value pairs. You can (and should) make the variables have a simple single-level scope, ie a valid file looks something like this: # # This is the config file, and # a '#' or ';' character indicates # a comment # ; core variables [core] ; Don't trust file modes filemode = false ; Our diff algorithm [diff] external = "/usr/local/bin/gnu-diff -u" renames = true which parses into three variables: "core.filemode" is associated with the string "false", and "diff.external" gets the appropriate quoted value. Right now we only react to one variable: "core.filemode" is a boolean that decides if we should care about the 0100 (user-execute) bit of the stat information. Even that is just a parsing demonstration - this doesn't actually implement that st_mode compare logic itself. Different programs can react to different config options, although they should always fall back to calling "git_default_config()" on any config option name that they don't recognize.

[PATCH] Better error reporting for "git status"

2005-10-02T06:55:47Z

Instead of "git status" ignoring (and hiding) potential errors from the "git-update-index" call, make it exit if it fails, and show the error. In order to do this, use the "-q" flag (to ignore not-up-to-date files) and add a new "--unmerged" flag that allows unmerged entries in the index without any errors. This also avoids marking the index "changed" if an entry isn't actually modified, and makes sure that we exit with an understandable error message if the index is corrupt or unreadable. "read_cache()" no longer returns an error for the caller to check. Finally, make die() and usage() exit with recognizable error codes, if we ever want to check the failure reason in scripts.

Diff clean-up.

2005-09-25T06:50:43Z

This is a long overdue clean-up to the code for parsing and passing diff options. It also tightens some constness issues. Signed-off-by: Junio C Hamano

Show modified files in git-ls-files

2005-09-20T22:07:53Z

Add -m/--modified to show files that have been modified wrt. the index. [jc: The original came from Brian Gerst on Sep 1st but it only checked if the paths were cache dirty without actually checking the files were modified. I also added the usage string and a new test.] Signed-off-by: Junio C Hamano

[PATCH] Fix buffer overflow in ce_flush().

Add a check before appending SHA1 signature to write_buffer, flush it first if necessary. Signed-off-by: Junio C Hamano

[PATCH] Improve handling of "." and ".." in git-diff-*

2005-08-17T04:33:25Z

This fixes up usage of ".." (without an ending slash) and "." (with or without the ending slash) in the git diff family. It also fixes pathspec matching for the case of an empty pathspec, since a "." in the top-level directory (or enough ".." under subdirectories) will result in an empty pathspec. We used to not match it against anything, but it should in fact match everything. Signed-off-by: Linus Torvalds Signed-off-by: Junio C Hamano

[PATCH] mmap error handling

2005-07-30T00:21:48Z

I have reviewed all occurrences of mmap() in git and fixed three types of errors/defects: 1) The result is not checked. 2) The file descriptor is closed if mmap() succeeds, but not when it fails. 3) Various casts applied to -1 are used instead of MAP_FAILED, which is specifically defined to check mmap() return value. [jc: This is a second round of Pavel's patch. He fixed up the problem that close() potentially clobbering the errno from mmap, which the first round had.] Signed-off-by: Pavel Roskin Signed-off-by: Junio C Hamano

Make "ce_match_path()" a generic helper function

2005-07-14T23:55:06Z

... and make git-diff-files use it too. This all _should_ make the diffcore-pathspec.c phase unnecessary, since the diff'ers now all do the path matching early interally.
