* git-blame: no rev means start from the working tree file.Junio C Hamano2007-02-05
| | | | | | | | | | | | | | | | | 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 <file> 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 <junkio@cox.net>
* diff-index --cached --raw: show tree entry on the LHS for unmerged entries.Junio C Hamano2007-01-06
| | | | | | | | | | | | | 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 <tree> -- <path>" to restore absense of the path in the index from the tree. Signed-off-by: Junio C Hamano <junkio@cox.net>
* make commit message a little more consistent and confortingNicolas Pitre2006-12-15
| | | | | | | | | | | | 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.

* | Make git-cherry handle root treesRene Scharfe2006-10-26
|/ | | | | | | | | | | | | | | | | | | This patch on top of 'next' makes built-in git-cherry handle root commits. It moves the static function log-tree.c::diff_root_tree() to tree-diff.c and makes it more similar to diff_tree_sha1() by shuffling around arguments and factoring out the call to log_tree_diff_flush(). Consequently the name is changed to diff_root_tree_sha1(). It is a version of diff_tree_sha1() that compares the empty tree (= root tree) against a single 'real' tree. This function is then used in get_patch_id() to compute patch IDs for initial commits instead of SEGFAULTing, as the current code does if confronted with parentless commits.

* Colorize 'commit' lines in log uiJeff King2006-07-24
| | | | | | | | | | | | | | When paging through the output of git-whatchanged, the color cues help to visually navigate within a diff.

This patch colorizes the 'commit' line, customizable through diff.colors.commit and defaulting to yellow.

* diff: do not use configuration magic at the core-levelJunio C Hamano2006-07-08
| | | | | | | | | | | | | | | | | | | | The Porcelainish has become so much usable as the UI that there is not much reason people should be using the core programs by hand anymore. At this point we are better off making the behaviour of the core programs predictable by keeping them unaffected by the configuration variables. Otherwise they will become very hard to use as reliable building blocks. For example, "git-commit -a" internally uses git-diff-files to figure out the set of paths that need to be updated in the index, and we should never allow diff.renames that happens to be in the configuration to interfere (or slow down the process). The UI level configuration such as showing renamed diff and coloring are still honored by the Porcelainish ("git log" family and "git diff"), but not by the core anymore.

This adds parsing of -U and --unified, both with an optional numeric argument. So now you can just say git diff --unified=5 to get a unified diff with a five-line context, instead of having to do something silly like GIT_DIFF_OPTS="--unified=5" git diff -u (that silly format does continue to still work, of course).

Currently there are two mechanisms defined: "literal" and "delta". The former records the deflated postimage and the latter records the deflated delta from the preimage to postimage. For purely implementation convenience, I added the deflated length after these "literal/delta" tokens (otherwise the decoding side needs to guess and reallocate the buffer while inflating).

Ok, this was nastier than expected, just because the dependencies between the different log-printing stuff were absolutely _everywhere_, but here's a patch that does exactly that. The patch is not very easy to read, and the "--patch-with-stat" thing is still broken (it does not call the "show_log()" thing properly for merges). That's not a new bug. In the new world order it _should_ do something like if (rev->logopt) show_log(rev, rev->logopt, "---\n"); but it doesn't. I haven't looked at the --with-stat logic, so I left it alone. That said, this patch removes more lines than it adds, and in particular, the "cmd_log_wc()" loop is now a very clean: while ((commit = get_revision(rev)) != NULL) { log_tree_commit(rev, commit); free(commit->buffer); commit->buffer = NULL; } so it doesn't get much prettier than this. All the complexity is entirely hidden in log-tree.c, and any code that needs to flush the log literally just needs to do the "if (rev->logopt) show_log(...)" incantation. I had to make the combined_diff() logic take a "struct rev_info" instead of just a "struct diff_options", but that part is pretty clean. This does change "git whatchanged" from using "diff-tree" as the commit descriptor to "commit", and I changed one of the tests to reflect that new reality. Otherwise everything still passes, and my other tests look fine too. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NOTE! This makes "-c" be the default, which effectively means that merges are never ignored any more, and "-m" is a no-op. So it changes semantics. I would also like to make "--cc" the default if you do patches, but didn't actually do that. The raw output format is not wonderfully pretty, but it's distinguishable from a "normal patch" in that a normal patch with just one parent has just one colon at the beginning, while a multi-parent raw diff has <n> colons for <n> parents. So now, in the kernel, when you do git-diff-tree cce0cac125623f9b68f25dd1350f6d616220a8dd (to see the manual ARM merge that had a conflict in arch/arm/Kconfig), you get cce0cac125623f9b68f25dd1350f6d616220a8dd ::100644 100644 100644 4a63a8e2e45247a11c068c6ed66c6e7aba29ddd9 77eee38762d69d3de95ae45dd9278df9b8225e2c 2f61726d2f4b636f6e66696700dbf71a59dad287 arch/arm/Kconfig ie you see two colons (two parents), then three modes (parent modes followed by result mode), then three sha1s (parent sha1s followed by result sha1). Which is pretty close to the normal raw diff output. Cool/stupid exercise: $ git-whatchanged | grep '^::' | cut -f2- | sort | uniq -c | sort -n | less -S will show which files have needed the most file-level merge conflict resolution. Useful? Probably not. But kind of interesting.
