2015-07-01rev-list: disable --use-bitmap-index when pruning commitsLibravatar Jeff King1-0/+6
The reachability bitmaps do not have enough information to tell us which commits might have changed path "foo", so the current code produces wrong answers for: git rev-list --use-bitmap-index --count HEAD -- foo (it silently ignores the "foo" limiter). Instead, we should fall back to doing a normal traversal (it is OK to fall back rather than complain, because --use-bitmap-index is a pure optimization, and might not kick in for other reasons, such as there being no bitmaps in the repository).

2015-06-17test-lib.sh: fix color support when tput needs ~/.terminfoLibravatar Richard Hansen1-29/+28
If tput needs ~/.terminfo for the current $TERM, then tput will succeed before HOME is changed to $TRASH_DIRECTORY (causing color to be set to 't') but fail afterward. One possible way to fix this is to treat HOME like TERM: back up the original value and temporarily restore it before say_color() runs tput. Instead, pre-compute and save the color control sequences before changing either TERM or HOME. Use the saved control sequences in say_color() rather than call tput each time. This avoids the need to back up and restore the TERM and HOME variables, and it avoids the overhead of a subshell and two invocations of tput per call to say_color().

2015-06-15Revert "stash: require a clean index to apply"Libravatar Jeff King1-7/+0
This reverts commit ed178ef13a26136d86ff4e33bb7b1afb5033f908. That commit was an attempt to improve the safety of applying a stash, because the application process may create conflicted index entries, after which it is hard to restore the original index state. Unfortunately, this hurts some common workflows around "git stash -k", like: git add -p ;# (1) stage set of proposed changes git stash -k ;# (2) get rid of everything else make test ;# (3) make sure proposal is reasonable git stash apply ;# (4) restore original working tree If you "git commit" between steps (3) and (4), then this just works. However, if these steps are part of a pre-commit hook, you don't have that opportunity (you have to restore the original state regardless of whether the tests passed or failed). It's possible that we could provide better tools for this sort of workflow. In particular, even before ed178ef, it could fail with a conflict if there were conflicting hunks in the working tree and index (since the "stash -k" puts the index version into the working tree, and we then attempt to apply the differences between HEAD and the old working tree on top of that). But the fact remains that people have been using it happily for a while, and the safety provided by ed178ef is simply not that great. Let's revert it for now. In the long run, people can work on improving stash for this sort of workflow, but the safety tradeoff is not worth it in the meantime.

2015-06-01format-patch: do not feed tags to clear_commit_marks()Libravatar Junio C Hamano1-0/+8
"git format-patch --ignore-if-in-upstream A..B", when either A or B is a tag, failed miserably. This is because the code passes the tips it used for traversal to clear_commit_marks(), after running a temporary revision traversal to enumerate the commits on both branches to find if they have commits that make equivalent changes. The revision traversal machinery knows how to enumerate commits reachable starting from a tag, but clear_commit_marks() wants to take nothing but a commit. In the longer term, it might be a more correct fix to teach clear_commit_marks() to do the same "committish to commit" dereferencing that is done in the revision traversal machinery, but for now this fix should suffice.

2015-06-01silence broken link warnings with revs->ignore_missing_linksLibravatar Jeff King1-0/+15
We set revs->ignore_missing_links to instruct the revision-walking machinery that we know the history graph may be incomplete. For example, we use it when walking unreachable but recent objects; we want to add what we can, but it's OK if the history is incomplete. However, we still print error messages for the missing objects, which can be confusing. This is not an error, but just a normal situation when transitioning from a repository last pruned by an older git (which can leave broken segments of history) to a more recent one (where we try to preserve whole reachable segments).

2015-05-29setup_git_directory: delay core.bare/core.worktree errorsLibravatar Jeff King1-8/+16
If both core.bare and core.worktree are set, we complain about the bogus config and die. Dying is good, because it avoids commands running and doing damage in a potentially incorrect setup. But dying _there_ is bad, because it means that commands which do not even care about the work tree cannot run. This can make repairing the situation harder: [setup] $ git config core.bare true $ git config core.worktree /some/path [OK, expected.] $ git status fatal: core.bare and core.worktree do not make sense [Hrm...] $ git config --unset core.worktree fatal: core.bare and core.worktree do not make sense [Nope...] $ git config --edit fatal: core.bare and core.worktree do not make sense [Gaaah.] $ git help config fatal: core.bare and core.worktree do not make sense Instead, let's issue a warning about the bogus config when we notice it (i.e., for all commands), but only die when the command tries to use the work tree (by calling setup_work_tree). So we now get: $ git status warning: core.bare and core.worktree do not make sense fatal: unable to set up work tree using invalid config $ git config --unset core.worktree warning: core.bare and core.worktree do not make sense We have to update t1510 to accomodate this; it uses symbolic-ref to check whether the configuration works or not, but of course that command does not use the working tree. Instead, we switch it to use `git status`, as it requires a work-tree, does not need any special setup, and is read-only (so a failure will not adversely affect further tests). In addition, we add a new test that checks the desired behavior (i.e., that running "git config" with the bogus config does in fact work).

2015-05-25http-backend: spool ref negotiation requests to bufferLibravatar Jeff King1-0/+11
When http-backend spawns "upload-pack" to do ref negotiation, it streams the http request body to upload-pack, who then streams the http response back to the client as it reads. In theory, git can go full-duplex; the client can consume our response while it is still sending the request. In practice, however, HTTP is a half-duplex protocol. Even if our client is ready to read and write simultaneously, we may have other HTTP infrastructure in the way, including the webserver that spawns our CGI, or any intermediate proxies. In at least one documented case[1], this leads to deadlock when trying a fetch over http. What happens is basically: 1. Apache proxies the request to the CGI, http-backend. 2. http-backend gzip-inflates the data and sends the result to upload-pack. 3. upload-pack acts on the data and generates output over the pipe back to Apache. Apache isn't reading because it's busy writing (step 1). This works fine most of the time, because the upload-pack output ends up in a system pipe buffer, and Apache reads it as soon as it finishes writing. But if both the request and the response exceed the system pipe buffer size, then we deadlock (Apache blocks writing to http-backend, http-backend blocks writing to upload-pack, and upload-pack blocks writing to Apache). We need to break the deadlock by spooling either the input or the output. In this case, it's ideal to spool the input, because Apache does not start reading either stdout _or_ stderr until we have consumed all of the input. So until we do so, we cannot even get an error message out to the client. The solution is fairly straight-forward: we read the request body into an in-memory buffer in http-backend, freeing up Apache, and then feed the data ourselves to upload-pack. But there are a few important things to note: 1. We limit the in-memory buffer to prevent an obvious denial-of-service attack. This is a new hard limit on requests, but it's unlikely to come into play. The default value is 10MB, which covers even the ridiculous 100,000-ref negotation in the included test (that actually caps out just over 5MB). But it's configurable on the off chance that you don't mind spending some extra memory to make even ridiculous requests work. 2. We must take care only to buffer when we have to. For pushes, the incoming packfile may be of arbitrary size, and we should connect the input directly to receive-pack. There's no deadlock problem here, though, because we do not produce any output until the whole packfile has been read. For upload-pack's initial ref advertisement, we similarly do not need to buffer. Even though we may generate a lot of output, there is no request body at all (i.e., it is a GET, not a POST).

2015-05-22rebase -i: fix post-rewrite hook with failed exec commandLibravatar Matthieu Moy1-1/+1
Usually, when 'git rebase' stops before completing the rebase, it is to give the user an opportunity to edit a commit (e.g. with the 'edit' command). In such cases, 'git rebase' leaves the sha1 of the commit being rewritten in "$state_dir"/stopped-sha, and subsequent 'git rebase --continue' will call the post-rewrite hook with this sha1 as <old-sha1> argument to the post-rewrite hook. The case of 'git rebase' stopping because of a failed 'exec' command is different: it gives the opportunity to the user to examine or fix the failure, but does not stop saying "here's a commit to edit, use --continue when you're done". So, there's no reason to call the post-rewrite hook for 'exec' commands. If the user did rewrite the commit, it would be with 'git commit --amend' which already called the post-rewrite hook. Fix the behavior to leave no stopped-sha file in case of failed exec command, and teach 'git rebase --continue' to skip record_in_rewritten if no stopped-sha file is found.

2015-05-20stash: complain about unknown flagsLibravatar Jeff King1-0/+4
The option parser for git-stash stuffs unknown flags into the $FLAGS variable, where they can be accessed by the individual commands. However, most commands do not even look at these extra flags, leading to unexpected results like this: $ git stash drop --help Dropped refs/stash@{0} (e6cf6d80faf92bb7828f7b60c47fc61c03bd30a1) We should notice the extra flags and bail. Rather than annotate each command to reject a non-empty $FLAGS variable, we can notice that "stash show" is the only command that actually _wants_ arbitrary flags. So we switch the default mode to reject unknown flags, and let stash_show() opt into the feature.

2015-05-18subdirectory tests: code cleanup, uncomment testLibravatar Stefan Beller1-4/+7
Back when these tests were written, we wanted to make sure that Git notices it is in a bare repository and "git show -s HEAD" would refrain from complaining that HEAD might mean a file it sees in its current working directory (because it does not). But the version of Git back then didn't behave well, without (doubly) being told that it is inside a bare repository by exporting "GIT_DIR=.". The form of the test we originally wanted to have was left commented out as a reminder. Nowadays the test as originally intended works, so add it to the test suite. We'll keep the old test that explicitly sets GIT_DIR=. to make sure that use case will not regress. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-05-18pull: make pull.ff=true override merge.ffLibravatar Paul Tan1-0/+8
Since b814da8 (pull: add pull.ff configuration, 2014-01-15), running git-pull with the configuration pull.ff=false or pull.ff=only is equivalent to passing --no-ff and --ff-only to git-merge. However, if pull.ff=true, no switch is passed to git-merge. This leads to the confusing behavior where pull.ff=false or pull.ff=only is able to override merge.ff, while pull.ff=true is unable to. Fix this by adding the --ff switch if pull.ff=true, and add a test to catch future regressions. Furthermore, clarify in the documentation that pull.ff overrides merge.ff.

2015-05-18pull: handle --log=<n>Libravatar Paul Tan1-0/+17
Since efb779f (merge, pull: add '--(no-)log' command line option, 2008-04-06) git-pull supported the (--no-)log switch and would pass it to git-merge. 96e9420 (merge: Make '--log' an integer option for number of shortlog entries, 2010-09-08) implemented support for the --log=<n> switch, which would explicitly set the number of shortlog entries. However, git-pull does not recognize this option, and will instead pass it to git-fetch, leading to "unknown option" errors. Fix this by matching --log=* in addition to --log and --no-log. Implement a test for this use case. Signed-off-by: Paul Tan <pyokagan@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-05-18sha1_file: pass empty buffer to index empty fileLibravatar Jim Hill1-0/+26
`git add` of an empty file with a filter pops complaints from `copy_fd` about a bad file descriptor. This traces back to these lines in sha1_file.c:index_core: if (!size) { ret = index_mem(sha1, NULL, size, type, path, flags); The problem here is that content to be added to the index can be supplied from an fd, or from a memory buffer, or from a pathname. This call is supplying a NULL buffer pointer and a zero size. Downstream logic takes the complete absence of a buffer to mean the data is to be found elsewhere -- for instance, these, from convert.c: if (params->src) { write_err = (write_in_full(child_process.in, params->src, params->size) < 0); } else { write_err = copy_fd(params->fd, child_process.in); } ~If there's a buffer, write from that, otherwise the data must be coming from an open fd.~ Perfectly reasonable logic in a routine that's going to write from either a buffer or an fd. So change `index_core` to supply an empty buffer when indexing an empty file. There's a patch out there that instead changes the logic quoted above to take a `-1` fd to mean "use the buffer", but it seems to me that the distinction between a missing buffer and an empty one carries intrinsic semantics, where the logic change is adapting the code to handle incorrect arguments.
