2012-05-07clone: fix progress-regressionLibravatar Erik Faye-Lund1-1/+1
In 5bd631b3 ("clone: support multiple levels of verbosity"), the default behavior to show progress of the implicit checkout in the clone-command regressed so that progress was only shown if the verbose-option was specified. Fix this by making option_verbosity == 0 output progress as well. Signed-off-by: Erik Faye-Lund <kusmabite@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-01-12thin-pack: try harder to use preferred base objects as baseLibravatar Jeff King1-2/+7
When creating a pack using objects that reside in existing packs, we try to avoid recomputing futile delta between an object (trg) and a candidate for its base object (src) if they are stored in the same packfile, and trg is not recorded as a delta already. This heuristics makes sense because it is likely that we tried to express trg as a delta based on src but it did not produce a good delta when we created the existing pack. As the pack heuristics prefer producing delta to remove data, and Linus's law dictates that the size of a file grows over time, we tend to record the newest version of the file as inflated, and older ones as delta against it. When creating a thin-pack to transfer recent history, it is likely that we will try to send an object that is recorded in full, as it is newer. But the heuristics to avoid recomputing futile delta effectively forbids us from attempting to express such an object as a delta based on another object. Sending an object in full is often more expensive than sending a suboptimal delta based on other objects, and it is even more so if we could use an object we know the receiving end already has (i.e. preferred base object) as the delta base. Tweak the recomputation avoidance logic, so that we do not punt on computing delta against a preferred base object. The effect of this change can be seen on two simulated upload-pack workloads. The first is based on 44 reflog entries from my git.git origin/master reflog, and represents the packs that kernel.org sent me git updates for the past month or two. The second workload represents much larger fetches, going from git's v1.0.0 tag to v1.1.0, then v1.1.0 to v1.2.0, and so on. The table below shows the average generated pack size and the average CPU time consumed for each dataset, both before and after the patch: dataset | reflog | tags --------------------------------- before | 53358 | 2750977 size after | 32398 | 2668479 change | -39% | -3% --------------------------------- before | 0.18 | 1.12 CPU after | 0.18 | 1.15 change | +0% | +3% This patch makes a much bigger difference for packs with a shorter slice of history (since its effect is seen at the boundaries of the pack) though it has some benefit even for larger packs.

If the remote has no default fetch refspec, as in [remote "origin"] url = git://git.kernel.org/pub/scm/git/git.git fetch = +refs/heads/*:refs/remotes/upstream/* we would not update the fetch refspec and even if there is a ref called "refs/remotes/origin/master", we should not rename it, since it was not created by fetching from the remote.

When renaming a remote called 'o' using 'git remote rename o foo', git should also rename any remote-tracking branches for the remote. This does happen, but any remote-tracking branches starting with 'refs/remotes/o', such as 'refs/remotes/origin/bar', will also be renamed (to 'refs/remotes/foorigin/bar' in this case).

2011-09-11remote: write correct fetch spec when renaming remote 'remote'Libravatar Martin von Zweigbergk1-4/+8
When renaming a remote whose name is contained in a configured fetch refspec for that remote, we currently replace the first occurrence of the remote name in the refspec. This is correct in most cases, but breaks if the remote name occurs in the fetch refspec before the expected place. For example, we currently change [remote "remote"] url = git://git.kernel.org/pub/scm/git/git.git fetch = +refs/heads/*:refs/remotes/remote/* into [remote "origin"] url = git://git.kernel.org/pub/scm/git/git.git fetch = +refs/heads/*:refs/origins/remote/* Reduce the risk of changing incorrect sections of the refspec by matching the entire ":refs/remotes/<name>/" instead of just "<name>".

Leave check_for_new_submodule_commits() early when no name <-> path mappings for submodules are found in the configuration.

When asked if "refs///heads/master" is valid, check-ref-format says "Yes, it is well formed", and when asked to print canonical form, it shows "refs/heads/master". This is so that it can be tucked after "$GIT_DIR/" to form a valid pathname for a loose ref, and we normalize a pathname like "$GIT_DIR/refs///heads/master" to de-dup the slashes in it. Similarly, when asked if "/refs/heads/master" is valid, check-ref-format says "Yes, it is Ok", but the leading slash is not removed when printing, leading to "$GIT_DIR//refs/heads/master". Fix it to make sure such leading slashes are removed. Add tests that such refnames are accepted and normalized correctly.

2011-08-23clone: clone from a repository with relative alternatesLibravatar Junio C Hamano1-23/+68
Cloning from a local repository blindly copies or hardlinks all the files under objects/ hierarchy. This results in two issues: - If the repository cloned has an "objects/info/alternates" file, and the command line of clone specifies --reference, the ones specified on the command line get overwritten by the copy from the original repository. - An entry in a "objects/info/alternates" file can specify the object stores it borrows objects from as a path relative to the "objects/" directory. When cloning a repository with such an alternates file, if the new repository is not sitting next to the original repository, such relative paths needs to be adjusted so that they can be used in the new repository. This updates add_to_alternates_file() to take the path to the alternate object store, including the "/objects" part at the end (earlier, it was taking the path to $GIT_DIR and was adding "/objects" itself), as it is technically possible to specify in objects/info/alternates file the path of a directory whose name does not end with "/objects".

2011-08-11ls-files: fix pathspec display on errorLibravatar Clemens Buchacher3-7/+11
The following sequence of commands reveals an issue with error reporting of relative paths: $ mkdir sub $ cd sub $ git ls-files --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. $ git commit --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. This bug is visible only if the normalized path (i.e., the relative path from the repository root) is longer than the prefix. Otherwise, the code skips over the normalized path and reads from an unused memory location which still contains a leftover of the original command line argument. So instead, use the existing facilities to deal with relative paths correctly. Also fix inconsistency between "checkout" and "commit", e.g. $ cd Documentation $ git checkout nosuch.txt error: pathspec 'Documentation/nosuch.txt' did not match... $ git commit nosuch.txt error: pathspec 'nosuch.txt' did not match... by propagating the prefix down the codepath that reports the error.

2011-08-05fast-export: quote paths in outputLibravatar Jeff King1-7/+24
Many pathnames in a fast-import stream need to be quoted. In particular: 1. Pathnames at the end of an "M" or "D" line need quoting if they contain a LF or start with double-quote. 2. Pathnames on a "C" or "R" line need quoting as above, but also if they contain spaces. For (1), we weren't quoting at all. For (2), we put double-quotes around the paths to handle spaces, but ignored the possibility that they would need further quoting. This patch checks whether each pathname needs c-style quoting, and uses it. This is slightly overkill for (1), which doesn't actually need to quote many characters that vanilla c-style quoting does. However, it shouldn't hurt, as any implementation needs to be ready to handle quoted strings anyway. In addition to adding a test, we have to tweak a test which blindly assumed that case (2) would always use double-quotes, whether it needed to or not.

2011-07-22reset: give better reflog messagesLibravatar Jeff King1-33/+16
The reset command creates its reflog entry from argv. However, it does so after having run parse_options, which means the only thing left in argv is any non-option arguments. Thus you would end up with confusing reflog entries like: $ git reset --hard HEAD^ $ git reset --soft HEAD@{1} $ git log -2 -g --oneline 8e46cad HEAD@{0}: HEAD@{1}: updating HEAD 1eb9486 HEAD@{1}: HEAD^: updating HEAD However, we must also consider that some scripts may set GIT_REFLOG_ACTION before calling reset, and we need to show their reflog action (with our text appended). For example: rebase -i (squash): updating HEAD On top of that, we also set the ORIG_HEAD reflog action (even though it doesn't generally exist). In that case, the reset argument is somewhat meaningless, as it has nothing to do with what's in ORIG_HEAD. This patch changes the reset reflog code to show: $GIT_REFLOG_ACTION: updating {HEAD,ORIG_HEAD} as before, but only if GIT_REFLOG_ACTION is set. Otherwise, show: reset: moving to $rev for HEAD, and: reset: updating ORIG_HEAD for ORIG_HEAD (this is still somewhat superfluous, since we are in the ORIG_HEAD reflog, obviously, but at least we now mention which command was used to update it). While we're at it, we can clean up the code a bit: - Use strbufs to make the message. - Use the "rev" parameter instead of showing all options. This makes more sense, since it is the only thing impacting the writing of the ref. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
