* tests: remove some direct access to .git/logsdt/reflog-testsDavid Turner2015-07-2810-33/+37
| | | | | | | | | | | | | | | Alternate refs backends might store reflogs somewhere other than .git/logs. Change most test code that directly accesses .git/logs to instead use git reflog commands. There are still a few tests which need direct access to reflogs: to check reflog permissions, to manually create reflogs from scratch, to save/restore reflogs, to check the format of raw reflog data, and to remove not just reflog contents, but the reflogs themselves. All cases which don't need direct access have been modified. Signed-off-by: David Turner <dturner@twopensource.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

|\ | | | | | | | | | | | | A minor bugfix when pack bitmap is used with "rev-list --count". * jk/rev-list-no-bitmap-while-pruning: rev-list: disable --use-bitmap-index when pruning commits
| * rev-list: disable --use-bitmap-index when pruning commitsjk/rev-list-no-bitmap-while-pruningJeff King2015-07-011-0/+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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

There are two issues with that commit: * It is buggy.

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.

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.

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).

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.

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).

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.

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.

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.

Non-atomic updates ================== The atomicity of the reference transaction depends on all pre-checks being done in the first loop, before any changes have started being committed in the second loop. The problem is that write_ref_to_lockfile() (previously part of write_ref_sha1()), which is called from the second loop, contains two more checks: * It verifies that new_sha1 is a valid object * If the reference being updated is a branch, it verifies that new_sha1 points at a commit object (as opposed to a tag, tree, or blob). If either of these checks fails, the "transaction" is aborted during the second loop. But this might happen after some reference updates have already been permanently committed. In other words, the all-or-nothing promise of "git update-ref --stdin" could be violated. So these checks have to be moved to the first loop. File descriptor exhaustion ========================== The old code locked all of the references in the first loop, leaving all of the lockfiles open until later loops. Since we might be updating a lot of references, this could result in file descriptor exhaustion. The solution ============ After this patch, the code looks like for update in updates: acquire locks and check old_sha if changing value: write_ref_to_lockfile() else: close_ref() for update in updates: if changing value: commit_ref_update() for update in updates: if deleting value: unlink() rewrite packed-refs file for update in updates: if reference still locked: unlock_ref() This fixes both problems: 1. The pre-checks in write_ref_to_lockfile() are now done in the first loop, before any changes have been committed. If any of the checks fails, the whole transaction can now be rolled back correctly. 2. All lockfiles are closed in the first loop immediately after they are created (either by write_ref_to_lockfile() or by close_ref()). This means that there is never more than one open lockfile at a time, preventing file descriptor exhaustion. To simplify the bookkeeping across loops, add a new REF_NEEDS_COMMIT bit to update->flags, which keeps track of whether the corresponding lockfile needs to be committed, as opposed to just unlocked. (Since "struct ref_update" is internal to the refs module, this change is not visible to external callers.) This change fixes two tests in t1400.

Instead, check for such conflicts during the "locking" phase: * Teach is_refname_available() to take an "extras" parameter that can contain extra reference names with which the specified refname must not conflict. * Change lock_ref_sha1_basic() to take an "extras" parameter, which it passes through to is_refname_available(). * Change ref_transaction_commit() to pass "affected_refnames" to lock_ref_sha1_basic() as its "extras" argument. This change fixes a test case in t1404. This code is a bit stricter than it needs to be. We could conceivably allow reference "refs/foo/bar" to be created in the same transaction as "refs/foo" is deleted (or vice versa). But that would be complicated to implement, because it is not possible to lock "refs/foo/bar" while "refs/foo" exists as a loose reference, but on the other hand we don't want to delete some references before adding others (because that could leave a gap during which required objects are unreachable). There is also a complication that reflog files' paths can conflict. Any less-strict implementation would probably require tricks like the packing of all references before the start of the real transaction, or the use of temporary intermediate reference names. So for now let's accept too-strict checks. Some reference update transactions will be rejected unnecessarily, but they will be rejected in their entirety rather than leaving the repository in an intermediate state, as would happen now. Please note that there is still one kind of D/F conflict that is *not* handled correctly. If two processes are running at the same time, and one tries to create "refs/foo" at the same time that the other tries to create "refs/foo/bar", then they can race with each other. Both processes can obtain their respective locks ("refs/foo.lock" and "refs/foo/bar.lock"), proceed to the "commit" phase of ref_transaction_commit(), and then the slower process will discover that it cannot rename its lockfile into place (after possibly having committed changes to other references). There appears to be no way to fix this race without changing the locking policy, which in turn would require a change to *all* Git clients. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu>

The test of creating two conflicting references in the same transaction fails, leaving the transaction half-completed. This will be fixed later in this patch series. Please note that the error messages emitted in the case of conflicts are not very user-friendly. In particular, when the conflicts involve loose references, then the errors are reported as error: there are still refs under 'refs/foo' fatal: Cannot lock the ref 'refs/foo'. or error: unable to resolve reference refs/foo/bar: Not a directory fatal: Cannot lock the ref 'refs/foo/bar'. This is because lock_ref_sha1_basic() fails while trying to lock the new reference, before it even gets to the is_refname_available() check. This situation will also be improved later in this patch series. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu>

The commands in the "log" family prepare commit decorations for all refs upfront, and the actual string used in a decoration depends on how load_ref_decorations() is called very early in the process. By default, "git log --decorate" stores names with common prefixes such as "refs/heads" stripped; "git log --decorate=full" stores the full refnames. When the current_pointed_by_HEAD() function has to decide if "HEAD" points at the branch a decoration describes, however, what was passed to load_ref_decorations() to decide to strip (or keep) such a common prefix is long lost. This makes it impossible to reliably tell if a decoration that stores "refs/heads/master", for example, is the 'master' branch (under "--decorate" with prefix omitted) or 'refs/heads/master' branch (under "--decorate=full"). Keep what was passed to load_ref_decorations() in a global next to the global variable name_decoration, and use that to decide how to match what was read from "HEAD" and what is in a decoration.

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>
