2006-02-17git-repack: allow passing a couple of flags to pack-objects.Junio C Hamano

2006-02-17pack-objects: finishing touches.Junio C Hamano
This introduces --no-reuse-delta option to disable reusing of existing delta, which is a large part of the optimization introduced by this series. This may become necessary if repeated repacking makes delta chain too long. With this, the output of the command becomes identical to that of the older implementation. But the performance suffers greatly. It still allows reusing non-deltified representations; there is no point uncompressing and recompressing the whole text. It also adds a couple more statistics output, while squelching it under -q flag, which the last round forgot to do. $ time old-git-pack-objects --stdout >/dev/null <RL Generating pack...

It can create delta chains that are deeper than specified. A<--B<--C<--D E F G Suppose we have a delta chain A to D (A is stored in full either in a pack or as a loose object. B is depth1 delta relative to A, C is depth2 delta relative to B...) with loose objects E, F, G. And we are going to pack all of them. B, C and D are left as delta against A, B and C respectively. So A, E, F, and G are examined for deltification, and let's say we decided to keep E expanded, and store the rest as deltas like this: E<--F<--G<--A Oops. We ended up making D a bit too deep, didn't we? B, C and D form a chain on top of A! This is because we did not know what the final depth of A would be, when we checked objects and decided to keep the existing delta. Unfortunately, deferring the decision until just before the deltification is not an option. To be able to make B, C, and D candidates for deltification with the rest, we need to know the type and final unexpanded size of them, but the major part of the optimization comes from the fact that we do not read the delta data to do so -- getting the final size is quite an expensive operation. To prevent this from happening, we should keep A from being deltified. But how would we tell that, cheaply? To do this most precisely, after check_object() runs, each object that is used as the base object of some existing delta needs to be marked with the maximum depth of the objects we decided to keep deltified (in this case, D is depth 3 relative to A, so if no other delta chain that is longer than 3 based on A exists, mark A with 3). Then when attempting to deltify A, we would take that number into account to see if the final delta chain that leads to D becomes too deep. However, this is a bit cumbersome to compute, so we would cheat and reduce the maximum depth for A arbitrarily to depth/4 in this implementation. Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-02-12Add support for explicit type specifiers when calling git-repo-configPetr Baudis
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>

2006-02-07git-commit: revamp the git-commit semantics.Junio C Hamano
- "git commit" without _any_ parameter keeps the traditional behaviour. It commits the current index. We commit the whole index even when this form is run from a subdirectory. - "git commit --include paths..." (or "git commit -i paths...") is equivalent to: git update-index --remove paths... git commit - "git commit paths..." acquires a new semantics. This is an incompatible change that needs user training, which I am still a bit reluctant to swallow, but enough people seem to have complained that it is confusing to them. It 1. refuses to run if $GIT_DIR/MERGE_HEAD exists, and reminds trained git users that the traditional semantics now needs -i flag. 2. refuses to run if named paths... are different in HEAD and the index (ditto about reminding). Added paths are OK. 3. reads HEAD commit into a temporary index file. 4. updates named paths... from the working tree in this temporary index. 5. does the same updates of the paths... from the working tree to the real index. 6. makes a commit using the temporary index that has the current HEAD as the parent, and updates the HEAD with this new commit. - "git commit --all" can run from a subdirectory, but it updates the index with all the modified files and does a whole tree commit. - In all cases, when the command decides not to create a new commit, the index is left as it was before the command is run. This means that the two "git diff" in the following sequence: $ git diff $ git commit -a $ git diff would show the same diff if you abort the commit process by making the commit log message empty. This commit also introduces much requested --author option. $ git commit --author 'A U Thor <author@example.com>' Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-02-07git-rerere: reuse recorded resolve.Junio C Hamano
In a workflow that employs relatively long lived topic branches, the developer sometimes needs to resolve the same conflict over and over again until the topic branches are done (either merged to the "release" branch, or sent out and accepted upstream). This commit introduces a new command, "git rerere", to help this process by recording the conflicted automerge results and corresponding hand-resolve results on the initial manual merge, and later by noticing the same conflicted automerge and applying the previously recorded hand resolution using three-way merge.

2006-02-07Docs: split up pull-fetch-param.txtJ. Bruce Fields
The push and pull man pages include a bunch of shared text from pull-fetch-param.txt. This simplifies maintenance somewhat, but there's actually quite a bit of text that applies only to one or the other. So, separate out the push- and pull/fetch-specific text into pull-fetch-param.txt and git-push.txt, then include the largest chunk of common stuff (the description of protocols and url's) from urls.txt. That cuts some irrelevant stuff from the man pages without making us duplicate too much. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-02-06daemon: extend user-relative path notation.Junio C Hamano
Earlier, we made --base-path to automatically forbid user-relative paths, which was probably a mistake. This introduces --user-path (or --user-path=path) option to control the use of user-relative paths independently. The latter form of the option can be used to restrict accesses to a part of each user's home directory, similar to "public_html" some webservers supports. If we're invoked with --user-path=FOO option, then a URL of the form git://~USER/PATH/... resolves to the path HOME/FOO/PATH/..., where HOME is USER's home directory. [jc: This is much reworked by me so bugs are mine, but the original patch was done by Mark Wooding.] Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-02-02Documentation: git-diff-tree --cc also omits empty commitsJunio C Hamano

2006-01-31cvs-migration documentation updateJ. Bruce Fields
Here's some changes to the cvs-migration.txt. As usual, in my attempt to make things clearer someone may have found I've made them less so, or I may have just gotten something wrong; so any review is welcomed. I can break up this sort of thing into smaller steps if preferred, the monolothic patch is just a bit simpler for me for this sort of thing. I moved the material describing shared repository management from core-tutorial.txt to cvs-migration.txt, where it seems more appropriate, and combined two sections to eliminate some redundancy. I also revised the earlier sections of cvs-migration.txt, mainly trying to make it more concise. I've left the last section of cvs-migration.txt (on CVS annotate alternatives) alone for now.

Without this, there is no way to specify a remote executable when invoking git-pull/git-fetch as there is for git-clone. [jc: I have a mild suspicion that this is a broken environment (aka sysadmin disservice). It may be legal to configure your sshd to spawn named program without involving shell at all, and if your sysadmin does so and you have your git programs under your home directory, you would need something like this, but then I suspect you would need such workaround everywhere, not just git.
