|\ | | | | | | | | * jk/git-dir-lookup: standardize and improve lookup rules for external local repos
| * standardize and improve lookup rules for external local reposJeff King2012-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you specify a local repository on the command line of clone, ls-remote, upload-pack, receive-pack, or upload-archive, or in a request to git-daemon, we perform a little bit of lookup magic, doing things like looking in working trees for .git directories and appending ".git" for bare repos. For clone, this magic happens in get_repo_path. For everything else, it happens in enter_repo. In both cases, there are some ambiguous or confusing cases that aren't handled well, and there is one case that is not handled the same by both methods. This patch tries to provide (and test!) standard, sensible lookup rules for both code paths. The intended changes are: 1. When looking up "foo", we have always preferred a working tree "foo" (containing "foo/.git" over the bare "foo.git". But we did not prefer a bare "foo" over "foo.git". With this patch, we do so. 2. We would select directories that existed but didn't actually look like git repositories. With this patch, we make sure a selected directory looks like a git repo. Not only is this more sensible in general, but it will help anybody who is negatively affected by change (1) negatively (e.g., if they had "foo.git" next to its separate work tree "foo", and expect to keep finding "foo.git" when they reference "foo"). 3. The enter_repo code path would, given "foo", look for "foo.git/.git" (i.e., do the ".git" append magic even for a repo with working tree). The clone code path did not; with this patch, they now behave the same. In the unlikely case of a working tree overlaying a bare repo (i.e., a ".git" directory _inside_ a bare repo), we continue to treat it as a working tree (prefering the "inner" .git over the bare repo). This is mainly because the combination seems nonsensical, and I'd rather stick with existing behavior on the off chance that somebody is relying on it.

| * | grep: pre-load userdiff drivers when threadedJeff King2012-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The low-level grep_source code will automatically load the userdiff driver to see whether a file is binary. However, when we are threaded, it will load the drivers in a non-deterministic order, handling each one as its assigned thread happens to be scheduled. Meanwhile, the attribute lookup code (which underlies the userdiff driver lookup) is optimized to handle paths in sequential order (because they tend to share the same gitattributes files). Multi-threading the lookups destroys the locality and makes this optimization less effective. We can fix this by pre-loading the userdiff driver in the main thread, before we hand off the file to a worker thread. My best-of-five for "git grep foo" on the linux-2.6 repository went from: real 0m0.391s user 0m1.708s sys 0m0.584s to: real 0m0.360s user 0m1.576s sys 0m0.572s Not a huge speedup, but it's quite easy to do. The only trick is that we shouldn't perform this optimization if "-a" was used, in which case we won't bother checking whether the files are binary at all.

| * | convert git-grep to use grep_source interfaceJeff King2012-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The grep_source interface (as opposed to grep_buffer) will eventually gives us a richer interface for telling the low-level grep code about our buffers. Eventually this will lead to things like better binary-file handling. For now, it lets us drop a lot of now-redundant code. The conversion is mostly straight-forward. One thing to note is that the memory ownership rules for "struct grep_source" are different than the "struct work_item" found here (the former will copy things like the filename, rather than taking ownership). Therefore you will also see some slight tweaking of when filename buffers are released. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * | grep: move sha1-reading mutex into low-level codeJeff King2012-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The multi-threaded git-grep code needs to serialize access to the thread-unsafe read_sha1_file call. It does this with a mutex that is local to builtin/grep.c. Let's instead push this down into grep.c, where it can be used by both builtin/grep.c and grep.c. This will let us safely teach the low-level grep.c code tricks that involve reading from the object db. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * | grep: make locking flag globalJeff King2012-02-02

That changed with 0579f91 (grep: enable threading with -p and -W using lazy attribute lookup, 2011-12-12), which pushed the lookup of funcname attributes (which is not thread-safe) into the low-level grep code. As a result, the low-level code learned about a new global "grep_attr_mutex" to serialize access to the attribute code. A multi-threaded caller (e.g., builtin/grep.c) is expected to initialize the mutex and set "use_threads" in the grep_opt structure. The low-level code only uses the lock if use_threads is set. However, putting the use_threads flag into the grep_opt struct is not the most logical place. Whether threading is in use is not something that matters for each call to grep_buffer, but is instead global to the whole program (i.e., if any thread is doing multi-threaded grep, every other thread, even if it thinks it is doing its own single-threaded grep, would need to use the locking). In practice, this distinction isn't a problem for us, because the only user of multi-threaded grep is "git-grep", which does nothing except call grep. This patch turns the opt->use_threads flag into a global flag. More important than the nit-picking semantic argument above is that this means that the locking functions don't need to actually have access to a grep_opt to know whether to lock. Which in turn can make adding new locks simpler, as we don't need to pass around a grep_opt. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Like other callbacks, it used "-1" to signal error. But it returned "1" to indicate that it found something, and "0" otherwise; other callbacks simply returned "0" to indicate that no error occurred. This distinction was necessary at the time, because the userdiff namespace overlapped slightly with the color configuration namespace. So "diff.color.foo" could mean "the 'foo' slot of diff coloring" or "the 'foo' component of the "color" userdiff driver". Because the color-parsing code would die on an unknown color slot, we needed the userdiff code to indicate that it had matched the variable, letting us bypass the color-parsing code entirely. Later, in 8b8e862 (ignore unknown color configuration, 2009-12-12), the color-parsing code learned to silently ignore unknown slots. This means we no longer need to protect userdiff-matched variables from reaching the color-parsing code. We can therefore change the userdiff_config calling convention to a more normal one. This drops some code from each caller, which is nice. But more importantly, it reduces the cognitive load for readers who may wonder why userdiff_config is unlike every other config callback. There's no need to add a new test confirming that this works; t4020 already contains a test that sets diff.color.external.

This avoids regression for people who have been using "tag -n" to show the log messages of commits that are pointed at by lightweight tags. Test script is from Jeff King.

The second case is OK to silently ignore; however, the existing code leaked the buffer returned by read_sha1_file.

Unfortunately, this interacts rather badly for people who use --ff-only to make sure that their branch is free of local developments. It used to be possible to say: $ git checkout -b frotz v1.7.9~30 $ git merge --ff-only v1.7.9 and expect that the resulting tip of frotz branch matches v1.7.9^0 (aka the commit tagged as v1.7.9), but this fails with the updated Git with: fatal: Not possible to fast-forward, aborting. because a merge that merges v1.7.9 tag to v1.7.9~30 cannot be created by fast forwarding. We could teach users that now they have to do $ git merge --ff-only v1.7.9^0 but it is far more pleasant for users if we DWIMmed this ourselves. When an integrator pulls in a topic from a lieutenant via a signed tag, even when the work done by the lieutenant happens to fast-forward, the integrator wants to have a merge record, so the integrator will not be asking for --ff-only when running "git pull" in such a case. Therefore, this change should not regress the support for the use case v1.7.9 wanted to add. Signed-off-by: Junio C Hamano <gitster@pobox.com>

It is not lost (it becomes description of an unborn my-tpoic branch), but is not very useful. So detect such a case and error out to reduce the grief factor from this common mistake. This incidentally also errors out --edit-description when the HEAD points at an unborn branch (immediately after "init", or "checkout --orphan"), because at that point, you do not even have any commit that is part of your history and there is no point in describing how this particular branch is different from the branch it forked off of, which is the useful bit of information the branch description is designed to capture. We may want to special case the unborn case later, but that is outside the scope of this patch to prevent more common mistakes before 1.7.9 series gains too much widespread use.

Thus it seemed unlikely that the user would need extra guidance. After f824628 the _normal_ thing is to start an editor. Give at least an indication of why we are doing it. The sentence about justification is one of the few things about standard git that are not agnostic to the workflow that the user chose. However, f824628 was proposed by Linus specifically to discourage users from merging unrelated upstream progress into topic branches. So we may as well take another step in the same direction.

After 5 years of use in the field, it turns out that people perform too many unjustified merges of the upstream history into their topic branches. These merges are not just useless, but they are often not explained well, and making the end result unreadable when it gets time for merging their history back to their upstream. Earlier we added the "--edit" option to the command, so that people can edit the log message to explain and justify their merge commits. Let's take it one step further and spawn the editor by default when we are in an interactive session (i.e. the standard input and the standard output are pointing at the same tty device). There may be existing scripts that leave the standard input and the standard output of the "git merge" connected to whatever environment the scripts were started, and such invocation might trigger the above "interactive session" heuristics. GIT_MERGE_AUTOEDIT environment variable can be set to "no" at the beginning of such scripts to use the historical behaviour while the script runs. Note that this backward compatibility is meant only for scripts, and we deliberately do *not* support "merge.edit = yes/no/auto" configuration option to allow people to keep the historical behaviour.

But not all transport types support this. Remote helper with "import" capability will not return complete ref information until fetch is performed and therefore the clone cannot be delayed. foreign_vcs field in struct remote was used to detect this kind of transport and save the result. This is a mistake because foreign_vcs is designed to override url-based transport detection. As a result, if the same "struct transport *" object is used on many different urls and one of them attached remote transport, the following urls will be mistakenly attached to the same transport. This fault is worked around by dad0b3d (push: do not let configured foreign-vcs permanently clobbered - 2012-01-23) To fix this, detect incomplete refs from transport_get_remote_refs() by SHA-1. Incomplete ones must have null SHA-1 (*). Then revert changes related to foreign_cvs field in 6f48d39 and dad0b3d. A good thing from this change is that cloning smart http transport can also be delayed. Earlier it falls into the same category "remote transport, no delay". (*) Theoretically if one of the remote refs happens to have null SHA-1, it will trigger false alarm and the clone will not be delayed. But that chance may be too small for us to pay attention to.

This is OK when a remote represents a single remote repository, but fails miserably when pushing to locations with multiple URLs, like this: $ cat .git/config [remote "origin"] url = https://code.google.com/p/git-htmldocs/ url = github.com:gitster/git-htmldocs.git push = refs/heads/master:refs/heads/master $ git push The second url that is supposed to use the git-over-ssh transport mistakenly use https:// and fails with: error: Couldn't resolve host 'github.com:gitster' while accessing github.com:gitster/git-htmldocs.git/info/refs fatal: HTTP request failed The right solution would probably be to dedicate a separate field to store the detected external helper to be used, which is valid only during a single use of transport until it is disconnected, instead of overwriting foreign_vcs field, but in the meantime, this band-aid should suffice.
