2018-10-25repack -ad: prune the list of shallow commitsLibravatar Johannes Schindelin1-1/+1
`git repack` can drop unreachable commits without further warning, making the corresponding entries in `.git/shallow` invalid, which causes serious problems when deepening the branches. One scenario where unreachable commits are dropped by `git repack` is when a `git fetch --prune` (or even a `git fetch` when a ref was force-pushed in the meantime) can make a commit unreachable that was reachable before. Therefore it is not safe to assume that a `git repack -adlf` will keep unreachable commits alone (under the assumption that they had not been packed in the first place, which is an assumption at least some of Git's code seems to make). This is particularly important to keep in mind when looking at the `.git/shallow` file: if any commits listed in that file become unreachable, it is not a problem, but if they go missing, it *is* a problem. One symptom of this problem is that a deepening fetch may now fail with fatal: error in object: unshallow <commit-hash> To avoid this problem, let's prune the shallow list in `git repack` when the `-d` option is passed, unless `-A` is passed, too (which would force the now-unreachable objects to be turned into loose objects instead of being deleted). Additionally, we also need to take `--keep-reachable` and `--unpack-unreachable=<date>` into account. Note: an alternative solution discussed during the review of this patch was to teach `git fetch` to simply ignore entries in .git/shallow if the corresponding commits do not exist locally. A quick test, however, revealed that the .git/shallow file is written during a shallow *clone*, in which case the commits do not exist, either, but the "shallow" line *does* need to be sent. Therefore, this approach would be a lot more finicky than the approach presented by the this patch.

2018-10-25repack: point out a bug handling stale shallow infoLibravatar Johannes Schindelin1-0/+27
A `git fetch --prune` can turn previously-reachable objects unreachable, even commits that are in the `shallow` list. A subsequent `git repack -ad` will then unceremoniously drop those unreachable commits, and the `shallow` list will become stale. This means that when we try to fetch with a larger `--depth` the next time, we may end up with: fatal: error in object: unshallow <commit-hash> Reported by Alejandro Pauly.

2018-09-27fsck: detect submodule paths starting with dashLibravatar Jeff King1-0/+8
As with urls, submodule paths with dashes are ignored by git, but may end up confusing older versions. Detecting them via fsck lets us prevent modern versions of git from being a vector to spread broken .gitmodules to older versions. Compared to blocking leading-dash urls, though, this detection may be less of a good idea: 1. While such paths provide confusing and broken results, they don't seem to actually work as option injections against anything except "cd". In particular, the submodule code seems to canonicalize to an absolute path before running "git clone" (so it passes /your/clone/-sub). 2. It's more likely that we may one day make such names actually work correctly. Even after we revert this fsck check, it will continue to be a hassle until hosting servers are all updated. On the other hand, it's not entirely clear that the behavior in older versions is safe. And if we do want to eventually allow this, we may end up doing so with a special syntax anyway (e.g., writing "./-sub" in the .gitmodules file, and teaching the submodule code to canonicalize it when comparing). So on balance, this is probably a good protection. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-09-27submodule-config: ban submodule paths that start with a dashLibravatar Jeff King1-0/+20
We recently banned submodule urls that look like command-line options. This is the matching change to ban leading-dash paths. As with the urls, this should not break any use cases that currently work. Even with our "--" separator passed to git-clone, git-submodule.sh gets confused. Without the code portion of this patch, the clone of "-sub" added in t7417 would yield results like: /path/to/git-submodule: 410: cd: Illegal option -s /path/to/git-submodule: 417: cd: Illegal option -s /path/to/git-submodule: 410: cd: Illegal option -s /path/to/git-submodule: 417: cd: Illegal option -s Fetched in submodule path '-sub', but it did not contain b56243f8f4eb91b2f1f8109452e659f14dd3fbe4. Direct fetching of that commit failed. Moreover, naively adding such a submodule doesn't work: $ git submodule add $url -sub The following path is ignored by one of your .gitignore files: -sub even though there is no such ignore pattern (the test script hacks around this with a well-placed "git mv"). Unlike leading-dash urls, though, it's possible that such a path _could_ be useful if we eventually made it work. So this commit should be seen not as recommending a particular policy, but rather temporarily closing off a broken and possibly dangerous code-path. We may revisit this decision later. There are two minor differences to the tests in t7416 (that covered urls): 1. We don't have a "./-sub" escape hatch to make this work, since the submodule code expects to be able to match canonical index names to the path field (so you are free to add submodule config with that path, but we would never actually use it, since an index entry would never start with "./"). 2. After this patch, cloning actually succeeds. Since we ignore the submodule.*.path value, we fail to find a config stanza for our submodule at all, and simply treat it as inactive. We still check for the "ignoring" message. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-09-27submodule-config: ban submodule urls that start with dashLibravatar Jeff King1-0/+34
The previous commit taught the submodule code to invoke our "git clone $url $path" with a "--" separator so that we aren't confused by urls or paths that start with dashes. However, that's just one code path. It's not clear if there are others, and it would be an easy mistake to add one in the future. Moreover, even with the fix in the previous commit, it's quite hard to actually do anything useful with such an entry. Any url starting with a dash must fall into one of three categories: - it's meant as a file url, like "-path". But then any clone is not going to have the matching path, since it's by definition relative inside the newly created clone. If you spell it as "./-path", the submodule code sees the "/" and translates this to an absolute path, so it at least works (assuming the receiver has the same filesystem layout as you). But that trick does not apply for a bare "-path". - it's meant as an ssh url, like "-host:path". But this already doesn't work, as we explicitly disallow ssh hostnames that begin with a dash (to avoid option injection against ssh). - it's a remote-helper scheme, like "-scheme::data". This _could_ work if the receiver bends over backwards and creates a funny-named helper like "git-remote--scheme". But normally there would not be any helper that matches. Since such a url does not work today and is not likely to do anything useful in the future, let's simply disallow them entirely. That protects the existing "git clone" path (in a belt-and-suspenders way), along with any others that might exist. Our tests cover two cases: 1. A file url with "./" continues to work, showing that there's an escape hatch for people with truly silly repo names. 2. A url starting with "-" is rejected. Note that we expect case (2) to fail, but it would have done so even without this commit, for the reasons given above. So instead of just expecting failure, let's also check for the magic word "ignoring" on stderr. That lets us know that we failed for the right reason.

This reverts commit 7e25437d35a70791b345872af202eabfb3e1a8bc, reversing changes made to 00624d608cc69bd62801c93e74d1ea7a7ddd6598. v2.19.0-rc0~165^2~1 (submodule: ensure core.worktree is set after update, 2018-06-18) assumes an "absorbed" submodule layout, where the submodule's Git directory is in the superproject's .git/modules/ directory and .git in the submodule worktree is a .git file pointing there. In particular, it uses $GIT_DIR/modules/$name to find the submodule to find out whether it already has core.worktree set, and it uses connect_work_tree_and_git_dir if not, resulting in fatal: could not open sub/.git for writing The context behind that patch: v2.19.0-rc0~165^2~2 (submodule: unset core.worktree if no working tree is present, 2018-06-12) unsets core.worktree when running commands like "git checkout --recurse-submodules" to switch to a branch without the submodule. If a user then uses "git checkout --no-recurse-submodules" to switch back to a branch with the submodule and runs "git submodule update", this patch is needed to ensure that commands using the submodule directly are aware of the path to the worktree. It is late in the release cycle, so revert the whole 3-patch series. We can try again later for 2.20.

2018-09-07http-backend: allow empty CONTENT_LENGTHLibravatar Max Kirillov1-0/+11
According to RFC3875, empty environment variable is equivalent to unset, and for CONTENT_LENGTH it should mean zero body to read. However, unset CONTENT_LENGTH is also used for chunked encoding to indicate reading until EOF. At least, the test "large fetch-pack requests can be split across POSTs" from t5551 starts faliing, if unset or empty CONTENT_LENGTH is treated as zero length body. So keep the existing behavior as much as possible. Add a test for the case.

2018-08-30am: avoid directory rename detection when calling recursive merge machineryLibravatar Elijah Newren1-2/+2
Let's say you have the following three trees, where Base is from one commit behind either master or branch: Base : bar_v1, foo/{file1, file2, file3} branch: bar_v2, foo/{file1, file2}, goo/file3 master: bar_v3, foo/{file1, file2, file3} Using git-am (or am-based rebase) to apply the changes from branch onto master results in the following tree: Result: bar_merged, goo/{file1, file2, file3} This is not what users want; they did not rename foo/ -> goo/, they only renamed one file within that directory. The reason this happens is am constructs fake trees (via build_fake_ancestor()) of the following form: Base_bfa : bar_v1, foo/file3 branch_bfa: bar_v2, goo/file3 Combining these two trees with master's tree: master: bar_v3, foo/{file1, file2, file3}, You can see that merge_recursive_generic() would see branch_bfa as renaming foo/ -> goo/, and master as just adding both foo/file1 and foo/file2. As such, it ends up with goo/{file1, file2, file3} The core problem is that am does not have access to the original trees; it can only construct trees using the blobs involved in the patch. As such, it is not safe to perform directory rename detection within am -3. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This behavior can't be relied upon, e.g. with JSON.pm 2.50 and JSON::PP. A JSON::PP::Boolean object will be represented as "true" or "false". To work around this let's check if we have any refs left after we check for hashes and arrays, assume those are JSON objects, and coerce them to a known boolean value. The behavior of this test still looks odd to me. Why implement our own ad-hoc encoder just for some one-off test, as opposed to say Perl's own Data::Dumper with Sortkeys et al?

Given where valgrind runs I don't think this would ever become a portability issue in practice, but it's easier to just use the wrapper than introduce some exception for the "make test-lint" check being added here. 1. http://pubs.opengroup.org/onlinepubs/9699919799/utilities/head.html 2. https://github.com/openbsd/ports/commit/08d5d82eaefe5cf2f125ecc0c6a57df9cf91350c#diff-f7d3c4fabeed1691620d608f1534f5e5 Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-08-23t/lib-rebase.sh: support explicit 'pick' commands in 'fake_editor.sh'Libravatar SZEDER Gábor1-3/+3
The verbose output of the test 'reword without issues functions as intended' in 't3423-rebase-reword.sh', added in a9279c6785 (sequencer: do not squash 'reword' commits when we hit conflicts, 2018-06-19), contains the following error output: sed: -e expression #1, char 2: extra characters after command This error comes from within the 'fake-editor.sh' script created by 'lib-rebase.sh's set_fake_editor() function, and the root cause is the FAKE_LINES="pick 1 reword 2" variable in the test in question, in particular the "pick" word. 'fake-editor.sh' assumes 'pick' to be the default rebase command and doesn't support an explicit 'pick' command in FAKE_LINES. As a result, 'pick' will be used instead of a line number when assembling the following 'sed' script: sed -n picks/^pick/pick/p which triggers the aforementioned error. Luckily, this didn't affect the test's correctness: the erroring 'sed' command doesn't write anything to the todo script, and processing the rest of FAKE_LINES generates the desired todo script, as if that 'pick' command were not there at all. The minimal fix would be to remove the 'pick' word from FAKE_LINES, but that would leave us susceptible to similar issues in the future. Instead, teach the fake-editor script to recognize an explicit 'pick' command, which is still a fairly trivial change. In the future we might want to consider reinforcing this fake editor script with an &&-chain and stricter parsing of the FAKE_LINES variable (e.g. to error out when encountering unknown rebase commands or commands and line numbers in the wrong order).

2018-08-22t3420-rebase-autostash: don't try to grep non-existing filesLibravatar SZEDER Gábor1-4/+4
Several tests in 't3420-rebase-autostash.sh' start various rebase processes that are expected to fail because of merge conflicts. These tests then run '! grep' to ensure that the autostash feature did its job, and the dirty contents of a file is gone. However, due to the test repo's history and the choice of upstream branch that file shouldn't exist in the conflicted state at all. Consequently, this 'grep' doesn't fail as expected, because it can't find the dirty content, but it fails because it can't open the file. Tighten this check by using 'test_path_is_missing' instead, thereby avoiding unexpected errors from 'grep' as well.

2018-08-22t3903-stash: don't try to grep non-existing fileLibravatar SZEDER Gábor1-1/+1
The test 'store updates stash ref and reflog' in 't3903-stash.sh' creates a stash from a new file, runs 'git reset --hard' to throw away any modifications to the work tree, and then runs '! grep' to ensure that the staged contents are gone. Since the file didn't exist before, it shouldn't exist after 'git reset' either. Consequently, this 'grep' doesn't fail as expected, because it can't find the staged content, but it fails because it can't open the file. Tighten this check by using 'test_path_is_missing' instead, thereby avoiding an unexpected error from 'grep' as well.

2018-08-22t6018-rev-list-glob: fix 'empty stdin' testLibravatar SZEDER Gábor1-1/+1
Prior to d3c6751b18 (tests: make use of the test_must_be_empty function, 2018-07-27), in the test 'rev-list should succeed with empty output on empty stdin' in 't6018-rev-list-glob' the empty 'expect' file served dual purpose: besides specifying the expected output, as usual, it also served as empty input for 'git rev-list --stdin'. Then d3c6751b18 came along, and, as part of the conversion to 'test_must_be_empty', removed this empty 'expect' file, not realizing its secondary purpose. Redirecting stdin from the now non-existing file failed the test, but since this test expects failure in the first place, this issue went unnoticed. Redirect 'git rev-list's stdin explicitly from /dev/null to provide empty input. (Strictly speaking we don't need this redirection, because the test script's stdin is already redirected from /dev/null anyway, but I think it's better to be explicit about it.)

2018-08-22t4051-diff-function-context: read the right fileLibravatar SZEDER Gábor1-1/+1
The test ' context does not include preceding empty lines' in the block of tests 'change with long common tail and no context' in 't4051-diff-function-context.sh' tries to read the file 'long_common_tail.diff.diff', but that file doesn't exist as its name contains one more '.diff' suffixes than necessary. Despite this error the test still succeeded without checking what it's supposed to, because this erroneous read is done on the line: test "$(first_context_line <long_common_tail.diff.diff)" != " " which means that: - the command substitution hides the error, so it won't fail the test, and - the result of the command substitution is the empty string, which is, of course, not equal to a single space character, so the condition is fulfilled, and the test succeeds. As a minimal fix, fix the name of the file to be read. In the future we might want to reorganize this test script (1) to use 'test_cmp' instead of 'test's and command substitutions to catch failing commands and to provide helpful error messages, and (2) to specify what the expected result actually _is_ instead of what it isn't.

In the test 'checkout with autocrlf=input' in 't0020-crlf.sh', one of the 'has_cr' checks looks at the non-existing file 'two' instead of 'dir/two'. The test still succeeds, without actually checking what it was supposed to, because this check is expected to fail anyway. As a minimal fix, fix the name of the file to be checked.

Then '!' negates the failed exit status, the test continues, and eventually succeeds. Remove this command substitution and use 'test_must_fail' to ensure that 'git merge' fails.
