2018-10-07tests: order arguments to git-rev-list properlyMatthew DeVore3-29/+44
It is a common mistake to put positional arguments before flags when invoking git-rev-list. Order the positional arguments last. This patch skips git-rev-list invocations which include the --not flag, since the ordering of flags and positional arguments affects the behavior. This patch also skips invocations of git-rev-list that occur in command substitution in which the exit code is discarded, since fixing those properly will require a more involved cleanup.

2018-10-07t9109: don't swallow Git errors upstream of pipesMatthew DeVore1-13/+21
'git ... | foo' will mask any errors or crashes in git, so split up such pipes in this file. One testcase uses several separate pipe sequences in a row which are awkward to split up. Wrap the split-up pipe in a function so the awkwardness is not repeated. Also change that testcase's surrounding quotes from double to single to avoid premature string interpolation.

Some pipes in tests lose the exit code of git processes, which can mask unexpected behavior like crashes.

2018-10-07tests: standardize pipe placementMatthew DeVore7-250/+344
Instead of using a line-continuation and pipe on the second line, take advantage of the shell's implicit line continuation after a pipe character. So for example, instead of some long line \ | next line use some long line | next line And add a blank line before and after the pipe where it aids readability (it usually does). This better matches the coding style documented in Documentation/CodingGuidelines and used in shell scripts elsewhere in the tree.

The list of Don'ts for test writing has grown large such that it is hard to see at a glance which section an item is in. In other words, if I ignore a little bit of surrounding context, the "don'ts" look like "do's." To make the list more readable, prefix "Don't" in front of every first sentence in the items. Also, the "Keep in mind" list is out of place and awkward, because it was a very short "list" beneath two very long ones, and it seemed easy to miss under the list of "don'ts," and it only had one item. So move this item to the list of "do's" and phrase as "Remember..." Signed-off-by: Matthew DeVore <matvore@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Instead of running `test "foo" = "$(bar)"`, we prefix the whole thing with `echo`. Comparing to nearby tests makes it clear that this is just debug leftover. This line has actually been modified four times since it was introduced in e52290428b (General ref log reading improvements., 2006-05-19) and the `echo` has always survived. Let's finally drop it.

2018-09-28commit: fix erroneous BUG, 'multiple renames on the same target? how?'Elijah Newren2-0/+24
builtin/commit.c:prepare_to_commit() can call run_status() twice if using the editor, including status, and the user attempts to record a non-merge empty commit without explicit --allow-empty. If there is also a rename involved as well (due to using 'git add -N'), then a BUG in wt-status.c is triggered: BUG: wt-status.c:476: multiple renames on the same target? how? The reason we hit this bug is that both run_status() calls use the same struct wt_status * (named s), and s->change is not freed between runs. Changes are inserted into s with string_list_insert, which usually means that the second run just recomputes all the same results and overwrites what was computed the first time. However, ever since commit 176ea7479309 ("wt-status.c: handle worktree renames", 2017-12-27), wt-status started checking for renames and copies but also added a preventative check that d->rename_status wasn't already set and output a BUG message if it was. The problem isn't that there are multiple rename targets to a single path as the error implies, the problem is that 's' is not freed/cleared between the two run_status() calls. Ever since commit dc6b1d92ca9c ("wt-status: use settings from git_diff_ui_config", 2018-05-04), which stopped hardcoding DIFF_DETECT_RENAME and allowed users to ask for copy detection, this bug has also been triggerable with a copy instead of a rename. Fix the bug by clearing s->change. A better change might be to clean up all of s between the two run_status() calls. A good first step towards such a goal might be writing a function to free the necessary fields in the wt_status * struct; a cursory glance at the code suggests all of its allocated data is probably leaked. However, doing all that cleanup is a bigger task for someone else interested to tackle; just fix the bug for now.

2018-09-27fsck: detect submodule paths starting with dashJeff King2-0/+15
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 dashJeff King2-0/+22
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 dashJeff King2-0/+42
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.

2018-09-27submodule--helper: use "--" to signal end of clone optionsJeff King1-0/+1
When we clone a submodule, we call "git clone $url $path". But there's nothing to say that those components can't begin with a dash themselves, confusing git-clone into thinking they're options. Let's pass "--" to make it clear what we expect. There's no test here, because it's actually quite hard to make these names work, even with "git clone" parsing them correctly. And we're going to restrict these cases even further in future commits. So we'll leave off testing until then; this is just the minimal fix to prevent us from doing something stupid with a badly formed entry.

The previous commit showed that merge_file_one() was prone to be called when merge_file_1() should be, and since it is just a thin wrapper around merge_file_1() anyway and only has one caller left, let's just remove merge_file_one() entirely. (It also turns out that the one remaining caller of merge_file_one() has very broken code that needs to be completely rewritten, but that's the subject of a future patch series; for now, we're just translating it into a merge_file_1() call.)

2018-09-20merge-recursive: avoid wrapper function when unnecessary and wastefulElijah Newren1-4/+1
merge_file_one() is a convenience function taking a bunch of oids and modes, combining each pair into a diff_filespec, and then calling merge_file_1(). When we already start with diff_filespec's, we can just call merge_file_1() directly instead of splitting out the oids and modes for the wrapper to recombine into what we already had.

2018-09-20merge-recursive: set paths correctly when three-way merging contentElijah Newren1-40/+9
merge_3way() has code to mark different sides of the conflict with info about where the content comes from. If the names of the files involved match, it simply uses the branch name. If the names of the files do not match, it uses branchname:filename. Unfortunately, merge_content() previously always called it with one.path = a.path = b.path. Granted, it didn't have other path information available to it for years, but that was corrected by passing rename_conflict_info in commit 3c217c077a86 ("merge-recursive: Provide more info in conflict markers with file renames", 2011-08-11). In that commit, instead of just fixing the bug with the pathnames, it created fake branch names incorporating both the branch name and file name. This "fake branch" workaround was extended further when I pulled that logic out into a special function in commit dac4741554e7 ("merge-recursive: Create function for merging with branchname:file markers", 2011-08-11), and a number of other sites outside of merge_content() have been added which call into that. However, this Rube-Goldberg-esque setup is not merely duplicate code and unnecessary work, it also risked having other callsites invoke it in a way that would result in markers of the form branchname:filename:filename (i.e. with the filename repeated). Fix this whole mess by: - setting one.path, a.path, and b.path appropriately - calling merge_file_1() directly - deleting the merge_file_special_markers() workaround wrapper Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-09-20gc: fix regression in 7b0f229222 impacting --quietÆvar Arnfjörð Bjarmason2-1/+22
Fix a regression in my recent 7b0f229222 ("commit-graph write: add progress output", 2018-09-17). The newly added progress output for "commit-graph write" didn't check the --quiet option. Do so, and add a test asserting that this works as expected. Since the TTY prequisite isn't available everywhere let's add a version of this that both requires and doesn't require that. This test might be overly specific and will break if new progress output is added, but I think it'll serve as a good reminder to test the undertested progress mode(s).

2018-09-20Doc: use `--type=bool` instead of `--bool`Martin Ågren3-4/+4
After fb0dc3bac1 (builtin/config.c: support `--type=<type>` as preferred alias for `--<type>`, 2018-04-18) we have a more modern way of spelling `--bool`. Update all instances except those that explicitly document the "historical options" in git-config.txt. The other old-style type-specifiers already seem to be gone except for in that list of historical options. Tweak the grammar a little in config.txt while we are there.
