2019-11-20sequencer: handle rebase-merges for "onto" messageLibravatar Doan Tran Cong Danh1-0/+21
In order to work correctly, git-rebase --rebase-merges needs to make initial todo list with unique labels. Those unique labels is being handled by employing a hashmap and appending an unique number if any duplicate is found. But, we forget that beside those labels for side branches, we also have a special label `onto' for our so-called new-base. In a special case that any of those labels for side branches named `onto', git will run into trouble. Correct it.

2019-11-18rebase -r: let `label` generate safer labelsLibravatar Matthew Rogers1-0/+6
The `label` todo command in interactive rebases creates temporary refs in the `refs/rewritten/` namespace. These refs are stored as loose refs, i.e. as files in `.git/refs/rewritten/`, therefore they have to conform with file name limitations on the current filesystem in addition to the accepted ref format. This poses a problem in particular on NTFS/FAT, where e.g. the colon, double-quote and pipe characters are disallowed as part of a file name. Let's safeguard against this by replacing not only white-space characters by dashes, but all non-alpha-numeric ones. However, we exempt non-ASCII UTF-8 characters from that, as it should be quite possible to reflect branch names such as `↯↯↯` in refs/file names.

2019-11-18gitweb: escape URLs generated by href()Libravatar Jeff King1-1/+2
There's a cross-site scripting problem in gitweb, where it will print URLs generated by its href() helper without further quoting. This allows an attacker to point a victim to a specially crafted gitweb URL and inject arbitrary HTML into the resulting page (which the victim sees as coming from gitweb). The base of the URL comes from evaluate_uri(), which pulls the value of $REQUEST_URI via the CGI module. It tries to strip off $PATH_INFO, but fails to do so in some cases (including ones that contain special characters, like "+"). Most of the uses of the URL end up being passed to "$cgi->a(-href = href())", which will get quoted properly by the CGI module. But in a few places, we output them ourselves as part of manually-generated HTML, and whatever was in the original URL will appear unquoted in the output. Given that all of the nearby variables placed into this manual HTML _are_ quoted, it seems like the authors assumed that these URLs would not need quoting. So it's possible that the bug is actually in evaluate_uri(), which should be doing a more careful job of stripping $PATH_INFO. There's some discussion in a comment in that function, as well as the commit message in 81d3fe9f48 (gitweb: fix wrong base URL when non-root DirectoryIndex, 2009-02-15). But I'm not sure I understand it. Regardless, it's a good idea to quote these values at the point of insertion into the HTML output: 1. Even if there is a bug in evaluate_uri(), this would give us belt-and-suspenders protection. 2. evaluate_uri() is only handling the base. Some generated URLs will also mention arbitrary refs or filenames in the repositories, and these should be quoted anyway. 3. It should never _hurt_ to quote (and that's what all of the $cgi->a() calls are doing already). So there may be further work here, but this patch at least prevents the XSS vulnerability, and shouldn't make anything worse. The test here covers the calls in print_feed_meta(), but I manually audited every call to href() to see how its output was used, and quoted appropriately. Most of them are esc_attr(), as they're used in tag attributes, but I used esc_html() when the URLs were printed bare. The distinction is largely academic, as one is implemented as a wrapper for the other.

In a real webserver's CGI call, gitweb.cgi would typically see $REQUEST_URI set. This variable does impact how we display our URL in the resulting page, so let's try to make our test as realistic as possible (we can just use the $PATH_INFO our caller passed in, if any).

2019-11-14t7004: check existence of correct tagLibravatar Martin Ågren1-3/+3
We try to delete the non-existing tag "anothertag", but for the verifications, we check that the tag "myhead" doesn't exist. "myhead" isn't used in this test except for this checking. Comparing to the test two tests earlier, it looks like a copy-paste mistake. Perhaps it's overkill to check that `git tag -d` didn't decide to *create* a tag. But since we're trying to be this careful, let's actually check the correct tag. While we're doing this, let's use a more descriptive tag name instead -- "nonexistingtag" should be obvious.

2019-11-14Start to implement a built-in version of `git add --interactive`Libravatar Johannes Schindelin1-0/+4
Unlike previous conversions to C, where we started with a built-in helper, we start this conversion by adding an interception in the `run_add_interactive()` function when the new opt-in `add.interactive.useBuiltin` config knob is turned on (or the corresponding environment variable `GIT_TEST_ADD_I_USE_BUILTIN`), and calling the new internal API function `run_add_i()` that is implemented directly in libgit.a. At this point, the built-in version of `git add -i` only states that it cannot do anything yet. In subsequent patches/patch series, the `run_add_i()` function will gain more and more functionality, until it is feature complete. The whole arc of the conversion can be found in the PRs #170-175 at https://github.com/gitgitgadget/git. The "--helper approach" can unfortunately not be used here: on Windows we face the very specific problem that a `system()` call in Perl seems to close `stdin` in the parent process when the spawned process consumes even one character from `stdin`. Which prevents us from implementing the main loop in C and still trying to hand off to the Perl script. The very real downside of the approach we have to take here is that the test suite won't pass with `GIT_TEST_ADD_I_USE_BUILTIN=true` until the conversion is complete (the `--helper` approach would have let it pass, even at each of the incremental conversion steps).

2019-11-14stash: make sure we have a valid index before writing itLibravatar Thomas Gummerer1-1/+6
In 'do_apply_stash()' we refresh the index in the end. Since 34933d0eff ("stash: make sure to write refreshed cache", 2019-09-11), we also write that refreshed index when --quiet is given to 'git stash apply'. However if '--index' is not given to 'git stash apply', we also discard the index in the else clause just before. We need to do so because we use an external 'git update-index --add --stdin', which leads to an out of date in-core index. Later we call 'refresh_and_write_cache', which now leads to writing the discarded index, which means we essentially write an empty index file. This is obviously not correct, or the behaviour the user wanted. We should not modify the users index without being asked to do so. Make sure to re-read the index after discarding the current in-core index, to avoid dealing with outdated information. Instead we could also drop the 'discard_cache()' + 'read_cache()', however that would make it easy to fall into the same trap as 34933d0eff did, so it's better to avoid that. We can also drop the 'refresh_and_write_cache' completely in the quiet case. Previously in legacy stash we relied on 'git status' to refresh the index after calling 'git read-tree' when '--index' was passed to 'git apply'. However the 'reset_tree()' call that replaced 'git read-tree' always passes options that are equivalent to '-m', making the refresh of the index unnecessary.

With './t1234-foo.sh -r 5,6' we can run only specific test cases in a test script, but our test framwork still evaluates all lazy prereqs that the excluded test cases might depend on. This is unnecessary and produces verbose and trace output that can be distracting. This has been an issue ever since the '-r|--run=' options were introduced in 0445e6f0a1 (test-lib: '--run' to run only specific tests, 2014-04-30), because that commit added the check of the list of test cases specified with '-r' after evaluating the prereqs. Avoid this unnecessary prereq evaluation by checking the list of test cases specified with '-r' before looking at the prereqs. Note that GIT_SKIP_TESTS has always been checked before the prereqs, so prereqs necessary for tests skipped that way were not evaluated.

When git commands are placed in the upstream of a pipe, their return codes are lost. In this particular case, it is especially bad since we are testing the intricacies of `git log --graph` behavior and if we hit an unexpected failure or segfault, we want to know this.

2019-11-12pack-objects: avoid pointless oe_map_new_pack() callsLibravatar Jeff King1-0/+1
This patch fixes an extreme slowdown in pack-objects when you have more than 1023 packs. See below for numbers. Since 43fa44fa3b (pack-objects: move in_pack out of struct object_entry, 2018-04-14), we use a complicated system to save some per-object memory. Each object_entry structs gets a 10-bit field to store the index of the pack it's in. We map those indices into pointers using packing_data->in_pack_by_idx, which we initialize at the start of the program. If we have 2^10 or more packs, then we instead create an array of pack pointers, one per object. This is packing_data->in_pack. So far so good. But there's one other tricky case: if a new pack arrives after we've initialized in_pack_by_idx, it won't have an index yet. We solve that by calling oe_map_new_pack(), which just switches on the fly to the less-optimal in_pack mechanism, allocating the array and back-filling it for already-seen objects. But that logic kicks in even when we've switched to it already (whether because we really did see a new pack, or because we had too many packs in the first place). The result doesn't produce a wrong outcome, but it's very slow. What happens is this: - imagine you have a repo with 500k objects and 2000 packs that you want to repack. - before looking at any objects, we call prepare_in_pack_by_idx(). It starts allocating an index for each pack. On the 1024th pack, it sees there are too many, so it bails, leaving in_pack_by_idx as NULL. - while actually adding objects to the packing list, we call oe_set_in_pack(), which checks whether the pack already has an index. If it's one of the packs after the first 1023, then it doesn't have one, and we'll call oe_map_new_pack(). But there's no useful work for that function to do. We're already using in_pack, so it just uselessly walks over the complete list of objects, trying to backfill in_pack. And we end up doing this for almost 1000 packs (each of which may be triggered by more than one object). And each time it triggers, we may iterate over up to 500k objects. So in the absolute worst case, this is quadratic in the number of objects. The solution is simple: we don't need to bother checking whether the pack has an index if we've already converted to using in_pack, since by definition we're not going to use it. So we can just push the "does the pack have a valid index" check down into that half of the conditional, where we know we're going to use it. The current test in p5303 sadly doesn't notice this problem, since it maxes out at 1000 packs. If we add a new test to it at 2000 packs, it does show the improvement: Test HEAD^ HEAD ---------------------------------------------------------------------- 5303.12: repack (2000) 26.72(39.68+0.67) 15.70(28.70+0.66) -41.2% However, these many-pack test cases are rather expensive to run, so adding larger and larger numbers isn't appealing. Instead, we can show it off more easily by using GIT_TEST_FULL_IN_PACK_ARRAY, which forces us into the absolute worst case: no pack has an index, so we'll trigger oe_map_new_pack() pointlessly for every single object, making it truly quadratic. Here are the numbers (on git.git) with the included change to p5303: Test HEAD^ HEAD ---------------------------------------------------------------------- 5303.3: rev-list (1) 2.05(1.98+0.06) 2.06(1.99+0.06) +0.5% 5303.4: repack (1) 33.45(33.46+0.19) 2.75(2.73+0.22) -91.8% 5303.6: rev-list (50) 2.07(2.01+0.06) 2.06(2.01+0.05) -0.5% 5303.7: repack (50) 34.21(35.18+0.16) 3.49(4.50+0.12) -89.8% 5303.9: rev-list (1000) 2.87(2.78+0.08) 2.88(2.80+0.07) +0.3% 5303.10: repack (1000) 41.26(51.30+0.47) 10.75(20.75+0.44) -73.9% Again, those improvements aren't realistic for the 1-pack case (because in the real world, the full-array solution doesn't kick in), but it's more useful to be testing the more-complicated code path. While we're looking at this issue, we'll tweak one more thing: in oe_map_new_pack(), we call REALLOC_ARRAY(pack->in_pack). But we'd never expect to get here unless we're back-filling it for the first time, in which case it would be NULL. So let's switch that to ALLOC_ARRAY() for clarity, and add a BUG() to document the expectation. Unfortunately this code isn't well-covered in the test suite because it's inherently racy (it only kicks in if somebody else adds a new pack while we're in the middle of repacking).

Comparing glibc and musl's output for this command $ sed q t/t3900/ISO-2022-JP.txt| iconv -f ISO-2022-JP -t utf-8 | iconv -f utf-8 -t ISO-2022-JP | xxd glibc: 00000000: 1b24 4224 4f24 6c24 5224 5b24 551b 2842 .$B$O$l$R$[$U.(B 00000010: 0a . musl: 00000000: 1b24 4224 4f1b 2842 1b24 4224 6c1b 2842 .$B$O.(B.$B$l.(B 00000010: 1b24 4224 521b 2842 1b24 4224 5b1b 2842 .$B$R.(B.$B$[.(B 00000020: 1b24 4224 551b 2842 0a .$B$U.(B. Although musl iconv's output isn't optimal, it's still correct. From commit 7d509878b8, ("pretty.c: format string with truncate respects logOutputEncoding", 2014-05-21), we're encoding the message to utf-8 first, then format it and convert the message to the actual output encoding on git commit --squash. Thus, t3900::test_commit_autosquash_flags is failing on musl libc. Reencode to utf-8 before arranging rebase's todo list. By doing this, we also remove a breakage noticed by a test added in the previous commit. Signed-off-by: Doan Tran Cong Danh <congdanhqx@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-11-11t3900: demonstrate git-rebase problem with multi encodingLibravatar Doan Tran Cong Danh1-0/+29
We're using fixup!/squash! <subject> to mark if current commit will be used to be fixed up or squashed to a previous commit. However, if we're changing i18n.commitencoding after making the original commit but before making the fixing up, we couldn't find the original commit to do the fixup/squash. Add a test to demonstrate that problem. Helped-by: Jeff King <peff@peff.net> Signed-off-by: Doan Tran Cong Danh <congdanhqx@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
