Support 'diff=pgm' attribute

2007-04-23T05:16:14Z

This enhances the attributes mechanism so that external programs meant for existing GIT_EXTERNAL_DIFF interface can be specifed per path. To configure such a custom diff driver, first define a custom diff driver in the configuration: [diff "my-c-diff"] command = <> Then mark the paths that you want to use this custom driver using the attribute mechanism. *.c diff=my-c-diff The intent of this separation is that the attribute mechanism is used for specifying the type of the contents, while the configuration mechanism is used to define what needs to be done to that type of the contents, which would be specific to both platform and personal taste.

diff --quiet

2007-03-14T23:21:19Z

This adds the command line option 'quiet' to tell 'git diff-*' that we are not interested in the actual diff contents but only want to know if there is any change. This option automatically turns --exit-code on, and turns off output formatting, as it does not make much sense to show the first hit we happened to have found. The --quiet option is silently turned off (but --exit-code is still in effect, so is silent output) if postprocessing filters such as pickaxe and diff-filter are used. For all practical purposes I do not think of a reason to want to use these filters and not viewing the diff output. The backends have not been taught about the option with this patch. That is a topic for later rounds. Signed-off-by: Junio C Hamano

Remove unused diffcore_std_no_resolve

2007-03-14T23:21:19Z

This was only used by diff-tree-helper program, whose purpose was to translate a raw diff to a patch. Signed-off-by: Junio C Hamano

Allow git-diff exit with codes similar to diff(1)

2007-03-14T23:21:19Z

This introduces a new command-line option: --exit-code. The diff programs will return 1 for differences, return 0 for equality, and something else for errors. Signed-off-by: Alex Riesen Signed-off-by: Junio C Hamano

diff: make more cases implicit --no-index

2007-03-01T00:32:31Z

When specifying an absolute path, or a relative path pointing outside the working tree, do not fail, but roll your own diffopt parsing, and execute a --no-index diff. Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano

diff --no-index: also imitate the exit status of diff(1)

2007-02-26T09:20:55Z

diff sets the exit status to 0 when no changes were found, to 1 when changes were found, and 2 means error. We imitate this to be able to use "git diff" in the test scripts. (Actually, keeping in line with the rest of git, -1 is returned on error, which corresponds to an exit status 255). To find out if the diff is not empty, a member called "found_changes" was introduced in struct diff_options, which is set in builtin_diff() and fn_out_consume().

Teach git-diff-files the new option `--no-index`

2007-02-23T04:59:55Z

With this flag and given two paths, git-diff-files behaves as a GNU diff lookalike (plus the git goodies like --check, colour, etc.). This flag is also available in git-diff. It also works outside of a git repository. In addition, if git-diff{,-files} is called without revision or stage parameter, and with exactly two paths at least one of which is not tracked, the default is --no-index. So, you can now say git diff /etc/inittab /etc/fstab and it actually works! This also unifies the duplicated argument parsing between cmd_diff_files() and builtin_diff_files().

git-blame: no rev means start from the working tree file.

2007-02-05T22:55:11Z

Warning: this changes the semantics. This makes "git blame" without any positive rev to start digging from the working tree copy, which is made into a fake commit whose sole parent is the HEAD. It also adds --contents option to pretend as if the working tree copy has the contents of the named file. You can use '-' to make the command read from the standard input. If you want the command to start annotating from the HEAD commit, you need to explicitly give HEAD parameter. Signed-off-by: Junio C Hamano

diff-index --cached --raw: show tree entry on the LHS for unmerged entries.

2007-01-07T06:57:42Z

This updates the way diffcore represents an unmerged pair somewhat. It used to be that entries with mode=0 on both sides were used to represent an unmerged pair, but now it has an explicit flag. This is to allow diff-index --cached to report the entry from the tree when the path is unmerged in the index. This is used in updating "git reset -- " to restore absense of the path in the index from the tree. Signed-off-by: Junio C Hamano

make commit message a little more consistent and conforting

2006-12-16T06:29:54Z

It is nicer to let the user know when a commit succeeded all the time, not only the first time. Also the commit sha1 is much more useful than the tree sha1 in this case. This patch also introduces a -q switch to supress this message as well as the summary of created/deleted files. Signed-off-by: Nicolas Pitre Signed-off-by: Junio C Hamano
