2014-01-21t/perf: time rev-list with UNINTERESTING commitsLibravatar Jeff King1-0/+12
We time a straight "rev-list --all" and its "--object" counterpart, both going all the way to the root. However, we do not time a partial history walk. This patch adds an extreme case: a walk over a very small slice of history, but with a very large set of UNINTERESTING tips. This is similar to the connectivity check run by git on a small fetch, or the walk done by any pre-receive hooks that want to check incoming commits. This test reveals a performance regression in git v1.8.4.2, caused by fbd4a70 (list-objects: mark more commits as edges in mark_edges_uninteresting, 2013-08-16): Test fbd4a703^ fbd4a703 ------------------------------------------------------------------------------------------ 0001.1: rev-list --all 0.69(0.67+0.02) 0.69(0.68+0.01) +0.0% 0001.2: rev-list --all --objects 3.47(3.44+0.02) 3.48(3.44+0.03) +0.3% 0001.4: rev-list $commit --not --all 0.04(0.04+0.00) 0.04(0.04+0.00) +0.0% 0001.5: rev-list --objects $commit --not --all 0.04(0.03+0.00) 0.27(0.24+0.02) +575.0% Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-01-15revision: propagate flag bits from tags to pointeesLibravatar Junio C Hamano1-0/+11
With the previous fix 895c5ba3 (revision: do not peel tags used in range notation, 2013-09-19), handle_revision_arg() that processes command line arguments for the "git log" family of commands no longer directly places the object pointed by the tag in the pending object array when it sees a tag object. We used to place pointee there after copying the flag bits like UNINTERESTING and SYMMETRIC_LEFT. This change meant that any flag that is relevant to later history traversal must now be propagated to the pointed objects (most often these are commits) while starting the traversal, which is partly done by handle_commit() that is called from prepare_revision_walk(). We did propagate UNINTERESTING, but did not do so for others, most notably SYMMETRIC_LEFT. This caused "git log --left-right v1.0..." (where "v1.0" is a tag) to start losing the "leftness" from the commit the tag points at. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-01-15revision: mark contents of an uninteresting tree uninterestingLibravatar Junio C Hamano1-0/+6
"git rev-list --objects ^A^{tree} B^{tree}" ought to mean "I want a list of objects inside B's tree, but please exclude the objects that appear inside A's tree". we see the top-level tree marked as uninteresting (i.e. ^A^{tree} in the above example) and call mark_tree_uninteresting() on it; this unfortunately prevents us from recursing into the tree and marking the objects in the tree as uninteresting. The reason why "git log ^A A" yields an empty set of commits, i.e. we do not have a similar issue for commits, is because we call mark_parents_uninteresting() after seeing an uninteresting commit. The uninteresting-ness of the commit itself does not prevent its parents from being marked as uninteresting. Introduce mark_tree_contents_uninteresting() and structure the code in handle_commit() in such a way that it makes it the responsibility of the callchain leading to this function to mark commits, trees and blobs as uninteresting, and also make it the responsibility of the helpers called from this function to mark objects that are reachable from them. Note that this is a very old bug that probably dates back to the day when "rev-list --objects" was introduced. The line to clear tree->object.parsed at the end of mark_tree_contents_uninteresting() can be removed when this fix is merged to the codebase after 6e454b9a (clear parsed flag when we free tree buffers, 2013-06-05).

2014-01-15interpret_branch_name: find all possible @-marksLibravatar Jeff King1-0/+21
When we parse a string like "foo@{upstream}", we look for the first "@"-sign, and check to see if it is an upstream mark. However, since branch names can contain an @, we may also see "@foo@{upstream}". In this case, we check only the first @, and ignore the second. As a result, we do not find the upstream. We can solve this by iterating through all @-marks in the string, and seeing if any is a legitimate upstream or empty-at mark. Another strategy would be to parse from the right-hand side of the string. However, that does not work for the "empty_at" case, which allows "@@{upstream}". We need to find the left-most one in this case (and we then recurse as "HEAD@{upstream}"). Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-01-15interpret_branch_name: avoid @{upstream} past colonLibravatar Jeff King1-0/+16
get_sha1() cannot currently parse a valid object name like "HEAD:@{upstream}" (assuming that such an oddly named file exists in the HEAD commit). It takes two passes to parse the string: 1. It first considers the whole thing as a ref, which results in looking for the upstream of "HEAD:". 2. It finds the colon, parses "HEAD" as a tree-ish, and then finds the path "@{upstream}" in the tree. For a path that looks like a normal reflog (e.g., "HEAD:@{yesterday}"), the first pass is a no-op. We try to dwim_ref("HEAD:"), that returns zero refs, and we proceed with colon-parsing. For "HEAD:@{upstream}", though, the first pass ends up in interpret_upstream_mark, which tries to find the branch "HEAD:". When it sees that the branch does not exist, it actually dies rather than returning an error to the caller. As a result, we never make it to the second pass. One obvious way of fixing this would be to teach interpret_upstream_mark to simply report "no, this isn't an upstream" in such a case. However, that would make the error-reporting for legitimate upstream cases significantly worse. Something like "bogus@{upstream}" would simply report "unknown revision: bogus@{upstream}", while the current code diagnoses a wide variety of possible misconfigurations (no such branch, branch exists but does not have upstream, etc). However, we can take advantage of the fact that a branch name cannot contain a colon. Therefore even if we find an upstream mark, any prefix with a colon must mean that the upstream mark we found is actually a pathname, and should be disregarded completely. This patch implements that logic. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-01-15interpret_branch_name: always respect "namelen" parameterLibravatar Jeff King1-1/+14
interpret_branch_name gets passed a "name" buffer to parse, along with a "namelen" parameter representing its length. If "namelen" is zero, we fallback to the NUL-terminated string-length of "name". However, it does not necessarily follow that if we have gotten a non-zero "namelen", it is the NUL-terminated string-length of "name". E.g., when get_sha1() is parsing "foo:bar", we will be asked to operate only on the first three characters. Yet in interpret_branch_name and its helpers, we use string functions like strchr() to operate on "name", looking past the length we were given. This can result in us mis-parsing object names. We should instead be limiting our search to "namelen" bytes. There are three distinct types of object names this patch addresses: - The intrepret_empty_at helper uses strchr to find the next @-expression after our potential empty-at. In an expression like "@:foo@bar", it erroneously thinks that the second "@" is relevant, even if we were asked only to look at the first character. This case is easy to trigger (and we test it in this patch). - When finding the initial @-mark for @{upstream}, we use strchr. This means we might treat "foo:@{upstream}" as the upstream for "foo:", even though we were asked only to look at "foo". We cannot test this one in practice, because it is masked by another bug (which is fixed in the next patch). - The interpret_nth_prior_checkout helper did not receive the name length at all. This turns out not to be a problem in practice, though, because its parsing is so limited: it always starts from the far-left of the string, and will not tolerate a colon (which is currently the only way to get a smaller-than-strlen "namelen"). However, it's still worth fixing to make the code more obviously correct, and to future-proof us against callers with more exotic buffers.

2014-01-15fetch-pack: do not filter out one-level refsLibravatar Jeff King1-0/+11
Currently fetching a one-level ref like "refs/foo" does not work consistently. The outer "git fetch" program filters the list of refs, checking each against check_refname_format. Then it feeds the result to do_fetch_pack to actually negotiate the haves/wants and get the pack. The fetch-pack code does its own filter, and it behaves differently. The fetch-pack filter looks for refs in "refs/", and then feeds everything _after_ the slash (i.e., just "foo") into check_refname_format. But check_refname_format is not designed to look at a partial refname. It complains that the ref has only one component, thinking it is at the root (i.e., alongside "HEAD"), when in reality we just fed it a partial refname. As a result, we omit a ref like "refs/foo" from the pack request, even though "git fetch" then tries to store the resulting ref. If we happen to get the object anyway (e.g., because the ref is contained in another ref we are fetching), then the fetch succeeds. But if it is a unique object, we fail when trying to update "refs/foo". We can fix this by just passing the whole refname into check_refname_format; we know the part we were omitting is "refs/", which is acceptable in a refname. This at least makes the checks consistent with each other. This problem happens most commonly with "refs/stash", which is the only one-level ref in wide use. However, our test does not use "refs/stash", as we may later want to restrict it specifically (not because it is one-level, but because of the semantics of stashes). We may also want to do away with the multiple levels of filtering (which can cause problems when they are out of sync), or even forbid one-level refs entirely. However, those decisions can come later; this fixes the most immediate problem, which is the mismatch between the two.

Commit 43eb920 switched one of the sub-repository in this test to matching to prepare for a world where the default becomes "simple". However, the main repository needs a similar change. We did not notice any test failure when merged with b2ed944 (push: switch default from "matching" to "simple", 2013-01-04) because t5531.6 is trying to provoke a failure of "git push" due to a submodule check.

There is no guarantee that strbuf_read_file must error out for directories.

2014-01-02t0000: drop "known breakage" testLibravatar Jeff King1-3/+0
Having a simulated "known breakage" test means that the test suite will always tell us there is a bug to be fixed, even though it is only simulated. The right way to test this is in a sub-test, that can also check that we provide the correct exit status and output. Fortunately, we already have such a test (added much later by 5ebf89e). We could arguably get rid of the simulated success test immediately above, as well, as it is also redundant with the tests added in 5ebf89e. However, it does not have the annoying behavior of the "known breakage" test. It may also be easier to debug if the test suite is truly broken, since it is not a test-within-a-test, as the later tests are.

2014-01-02t0000: simplify HARNESS_ACTIVE hackLibravatar Jeff King2-11/+5
Commit 517cd55 set HARNESS_ACTIVE unconditionally in sub-tests, because that value affects the output of "--verbose". t0000 needs stable output from its sub-tests, and we may or may not be running under a TAP harness. That commit made the decision to always set the variable, since it has another useful side effect, which is suppressing writes to t/test-results by the sub-tests (which would just pollute the real results). Since the last commit, though, the sub-tests have their own test-results directories, so this is no longer an issue. We can now update a few comments that are no longer accurate nor necessary. We can also revisit the choice of HARNESS_ACTIVE. Since we must choose one value for stability, it's probably saner to have it off. This means that future patches could test things like the test-results writing, or the "--quiet" option, which is currently ignored when run under a harness.

2014-01-02t0000: set TEST_OUTPUT_DIRECTORY for sub-testsLibravatar Jeff King1-0/+2
Running t0000 produces more trash directories than expected and does not clean up after itself: $ ./t0000-basic.sh [...] $ ls -d trash\ directory.* trash directory.failing-cleanup trash directory.mixed-results1 trash directory.mixed-results2 trash directory.partial-pass trash directory.test-verbose trash directory.test-verbose-only-2 These scratch areas for sub-tests should be under the t0000 trash directory, but because TEST_OUTPUT_DIRECTORY defaults to TEST_DIRECTORY, which is exported to help sub-tests find test-lib.sh, the sub-test trash directories are created under the toplevel t/ directory instead. Because some of the sub-tests simulate failures, their trash directories are kept around. Fix it by explicitly setting TEST_OUTPUT_DIRECTORY appropriately for sub-tests. An alternative fix would be to pass the --root parameter that only specifies where to put the trash directories, which would also work. However, using TEST_OUTPUT_DIRECTORY is more futureproof in case tests want to write more output in addition to the test-results/ (which are already suppressed in sub-tests using the HARNESS_ACTIVE setting) and trash directories. This fixes a regression introduced by 38b074d (t/test-lib.sh: fix TRASH_DIRECTORY handling, 2013-04-14). Before that commit, the TEST_OUTPUT_DIRECTORY setting was not respected consistently so most tests did their work in a "trash" subdirectory of the current directory instead of the output dir.

2014-01-02use distinct username/password for http auth testsLibravatar Jeff King6-17/+26
The httpd server we set up to test git's http client code knows about a single account, in which both the username and password are "user@host" (the unusual use of the "@" here is to verify that we handle the character correctly when URL escaped). This means that we may miss a certain class of errors in which the username and password are mixed up internally by git. We can make our tests more robust by having distinct values for the username and password. In addition to tweaking the server passwd file and the client URL, we must teach the "askpass" harness to accept multiple values. As a bonus, this makes the setup of some tests more obvious; when we are expecting git to ask only about the password, we can seed the username askpass response with a bogus value.

2013-12-30replace info: rename 'full' to 'long' and clarify in-code symbolsLibravatar Christian Couder1-2/+2
Enum names SHORT/MEDIUM/FULL were too broad to be descriptive. And they clashed with built-in symbols on platforms like Windows. Clarify by giving them REPLACE_FORMAT_ prefix. Rename 'full' format in "git replace --format=<name>" to 'long', to match others (i.e. 'short' and 'medium').

2013-12-30merge-base --octopus: reduce the result from get_octopus_merge_bases()Libravatar Junio C Hamano1-0/+39
Scripts that use "merge-base --octopus" could do the reducing themselves, but most of them are expected to want to get the reduced results without having to do any work themselves. Tests are taken from a message by Василий Макаров <einmalfel@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com> --- We might want to vet the existing callers of the underlying get_octopus_merge_bases() and find out if _all_ of them are doing anything extra (like deduping) because the machinery can return duplicate results. And if that is the case, then we may want to move the dedupling down the callchain instead of having it here.
2013-12-27Remove the line length limit for graft filesLibravatar Johannes Schindelin2-1/+36
Support for grafts predates Git's strbuf, and hence it is understandable that there was a hard-coded line length limit of 1023 characters (which was chosen a bit awkwardly, given that it is *exactly* one byte short of aligning with the 41 bytes occupied by a commit name and the following space or new-line character). While regular commit histories hardly win comprehensibility in general if they merge more than twenty-two branches in one go, it is not Git's business to limit grafts in such a way. In this particular developer's case, the use case that requires substantially longer graft lines to be supported is the visualization of the commits' order implied by their changes: commits are considered to have an implicit relationship iff exchanging them in an interactive rebase would result in merge conflicts. Thusly implied branches tend to be very shallow in general, and the resulting thicket of implied branches is usually very wide; It is actually quite common that *most* of the commits in a topic branch have not even one implied parent, so that a final merge commit has about as many implied parents as there are commits in said branch.
