| * | Properly git-bisect reset after bisecting from non-master headPetr Baudis2006-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | git-bisect reset without an argument would return to master even if the bisecting started at a non-master branch. This patch makes it save the original branch name to .git/head-name and restore it afterwards. This is also compatible with Cogito and cg-seek, so cg-status will show that we are seeked on the bisect branch and cg-reset will properly restore the original branch. git-bisect start will refuse to work if it is not on a bisect but .git/head-name exists; this is to protect against conflicts with other seeking tools.

* git-commit: show dirtiness including index.Junio C Hamano2006-02-12
| | | | | | | | | | | | | Earlier, when we switched a branch we used diff-files to show paths that are dirty in the working tree. But we allow switching branches with updated index ("read-tree -m -u $old $new" works that way), and only showing paths that have differences in the working tree but not paths that are different in index was confusing. This shows both as modified from the top commit of the branch we just have switched to. Signed-off-by: Junio C Hamano <junkio@cox.net>

* Fix object re-hashingLinus Torvalds2006-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hashed object lookup had a subtle bug in re-hashing: it did for (i = 0; i < count; i++) if (objs[i]) { .. rehash .. where "count" was the old hash couny. Oon the face of it is obvious, since it clearly re-hashes all the old objects. However, it's wrong. If the last old hash entry before re-hashing was in use (or became in use by the re-hashing), then when re-hashing could have inserted an object into the hash entries with idx >= count due to overflow. When we then rehash the last old entry, that old entry might become empty, which means that the overflow entries should be re-hashed again. In other words, the loop has to be fixed to either traverse the whole array, rather than just the old count. (There's room for a slight optimization: instead of counting all the way up, we can break when we see the first empty slot that is above the old "count". At that point we know we don't have any collissions that we might have to fix up any more. This patch only does the trivial fix) [jc: with trivial fix on trivial fix] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

| * Add support for explicit type specifiers when calling git-repo-configPetr Baudis2006-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, git-repo-config will just return the raw value of option as specified in the config file; this makes things difficult for scripts calling it, especially if the value is supposed to be boolean. This patch makes it possible to ask git-repo-config to check if the option is of the given type (int or bool) and write out the value in its canonical form. If you do not pass --int or --bool, the behaviour stays unchanged and the raw value is emitted. This also incidentally fixes the segfault when option with no value is encountered. [jc: tweaked the option parsing a bit to make it easier to see that the patch does not change anything but the type stuff in the diff output. Also changed to avoid "foo ? : bar" construct. ] Signed-off-by: Petr Baudis <pasky@suse.cz> Signed-off-by: Junio C Hamano <junkio@cox.net>

* | Avoid using "git-var -l" until it gets fixed.Junio C Hamano2006-02-12
|/ | | | | | | | | | | | | | | | | | | | | | | | | This is to be nicer to people with unusable GECOS field. "git-var -l" is currently broken in that when used by a user who does not have a usable GECOS field and has not corrected it by exporting GIT_COMMITTER_NAME environment variable it dies when it tries to output GIT_COMMITTER_IDENT (same thing for AUTHOR). "git-pull" used "git-var -l" only because it needed to get a configuration variable before "git-repo-config --get" was introduced. Use the latter tool designed exactly for this purpose. "git-sh-setup" used "git-var GIT_AUTHOR_IDENT" without actually wanting to use its value. The only purpose was to cause the command to check and barf if the repository format version recorded in the $GIT_DIR/config file is too new for us to deal with correctly. Instead, use "repo-config --get" on a random property and see if it die()s, and check if the exit status is 128 (comes from die -- missing variable is reported with exit status 1, so we can tell that case apart).

* Fix fetch-clone in the presense of signalsLinus Torvalds2006-02-11
| | | | | | | | | | | | | | | | | We shouldn't fail a fetch just because a signal might have interrupted the read. Normally, we don't install any signal handlers, so EINTR really shouldn't happen. That said, really old versions of Linux will interrupt an interruptible system call even for signals that turn out to be ignored (SIGWINCH is the classic example - resizing your xterm would cause it). The same might well be true elsewhere too. Also, since receive_keep_pack() doesn't control the caller, it can't know that no signal handlers exist.

* Make "git clone" less of a deathly quiet experienceLinus Torvalds2006-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It used to be that "git-unpack-objects" would give nice percentages, but now that we don't unpack the initial clone pack any more, it doesn't. And I'd love to do that nice percentage view in the pack objects downloader too, but the thing doesn't even read the pack header, much less know how much it's going to get, so I was lazy and didn't. Instead, it at least prints out how much data it's gotten, and what the packing speed is. Which makes the user realize that it's actually doing something useful instead of sitting there silently (and if the recipient knows how large the final result is, he can at least make a guess about when it migt be done). So with this patch, I get something like this on my DSL line: [torvalds@g5 ~]$ time git clone master.kernel.org:/pub/scm/linux/kernel/git/torvalds/linux-2.6 clone-test Packing 188543 objects 48.398MB (154 kB/s) where even the speed approximation seems to be roughtly correct (even though my algorithm is a truly stupid one, and only really gives "speed in the last half second or so"). Anyway, _something_ like this is definitely needed. It could certainly be better (if it showed the same kind of thing that git-unpack-objects did, that would be much nicer, but would require parsing the object stream as it comes in). But this is big step forward, I think. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This shows "new file mode XXXX" and "deleted file mode XXXX" lines like two-way diff-patch output does, by checking the status from each parent. The diff-raw output for combined diff is made a bit uglier by showing diff status letters with each parent. While most of the case you would see "MM" in the output, an Evil Merge that touches a path that was added by inheriting from one parent is possible and it would be shown like these: $ git-diff-tree --abbrev -c HEAD 2d7ca89675eb8888b0b88a91102f096d4471f09f ::000000 000000 100644 0000000... 0000000... 31dd686...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This way, diff-files can make use of it. Also implement the full suite of what diff_flush_raw() supports just for consistency. With this, 'diff-tree -c -r --name-status' would show what is expected. There is no way to get the historical output (useful for debugging and low-level Plumbing work) anymore, so tentatively it makes '-m' to mean "do not combine and show individual diffs with parents". diff-files matches diff-tree to produce raw output for -c.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This revamps the git-status command to take the same set of parameters as git commit. It gives a preview of what is being committed with that command. With -v flag, it shows the diff output between the HEAD commit and the index that would be committed if these flags were given to git-commit command. git-commit also acquires -v flag (it used to mean "verify" but that is the default anyway and there is --no-verify to turn it off, so not much is lost), which uses the updated git-status -v to seed the commit log buffer. This is handy for writing a log message while reviewing the changes one last time. Now, git-commit and git-status are internally share the same implementation. Unlike previous git-commit change, this uses a temporary index to prepare the index file that would become the real index file after a successful commit, and moves it to the real index file once the commit is actually made. This makes it safer than the previous scheme, which stashed away the original index file and restored it after an aborted commit. Signed-off-by: Junio C Hamano <junkio@cox.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After experimenting with code to add the ability to encode a delta against part of the deltified file, it turns out that resulting packs are _bigger_ than when this ability is not used. The raw delta output might be smaller, but it doesn't compress as well using gzip with a negative net saving on average. Said bit would in fact be more useful to allow for encoding the copying of chunks larger than 64KB providing more savings with large files. This will correspond to packs version 3. While the current code still produces packs version 2, it is made future proof so pack versions 2 and 3 are accepted. Any pack version 2 are compatible with version 3 since the redefined bit was never used before. When enough time has passed, code to use that bit to produce version 3 packs could be added.

There certainly are optimizations possible, but then the code becomes almost the same as that in coreutil's lib/mkdir-p.c. Other uses of EEXIST seem ok. Tested on Solaris 8, AIX 5.2L, and a few Linux versions. AIX has some unrelated (I think) failures right now; I haven't tried many recent gits there. Anyone have an old Ultrix box to break everything? ;) Also remove extraneous #includes. Everything's already in git-compat-util.h, included through cache.h.
