"git push --force-with-lease" already had enough logic to allow ensuring that such a push results in creation of a ref (i.e. the receiving end did not have another push from sideways that would be discarded by our force-pushing), but didn't expose this possibility to the users.

There are certain house-keeping tasks that need to be performed at the very beginning of any Git program, and programs that are not built-in commands had to do them exactly the same way as "git" potty does. It was easy to make mistakes in one-off standalone programs (like test helpers).

2016-08-16t/Makefile: ensure that paths are valid on platforms we careLibravatar Johannes Schindelin1-1/+10
Some pathnames that are okay on ext4 and on HFS+ cannot be checked out on Windows. Tests that want to see operations on such paths on filesystems that support them must do so behind appropriate test prerequisites, and must not include them in the source tree (instead they should create them when they run). Otherwise, the source tree cannot even be checked out. Make sure that double-quotes, asterisk, colon, greater/less-than, question-mark, backslash, tab, vertical-bar, as well as any non-ASCII characters never appear in the pathnames with a new test-lint-* target as part of a `make test`. To that end, we call `git ls-files` (ensuring that the paths are quoted properly), relying on the fact that paths containing non-ASCII characters are quoted within double-quotes. In case that the source code does not actually live in a Git repository (e.g. when extracted from a .zip file), or that the `git` executable cannot be executed, we simply ignore the error for now; In that case, our trusty Continuous Integration will be the last line of defense and catch any problematic file name. Noticed when a topic wanted to add a pathname with '>' in it. A check like this will prevent a similar problems from happening in the future.

2016-08-13merge-recursive: fix verbose output for multiple base treesLibravatar René Scharfe1-0/+18
One of the indirect callers of make_virtual_commit() passes the result of oid_to_hex() as the name, i.e. a pointer to a static buffer. Since the function uses that string pointer directly in building a struct merge_remote_desc, multiple entries can end up sharing the same name inadvertently. Fix that by calling set_merge_remote_desc(), which creates a copy of the string, instead of building the struct by hand.

There is an optimization used in "git diff $treeA $treeB" to borrow an already checked-out copy in the working tree when it is known to be the same as the blob being compared, expecting that open/mmap of such a file is faster than reading it from the object store, which involves inflating and applying delta.

2016-08-04t5533: make it pass on case-sensitive filesystemsLibravatar Johannes Schindelin1-1/+1
The newly-added test case wants to commit a file "c.t" (note the lower case) when a previous test case already committed a file "C.t". This confuses Git to the point that it thinks "c.t" was not staged when "git add c.t" was called. Simply make the naming of the test commits consistent with the previous test cases: use upper-case, and advance in the alphabet. This came up in local work to rebase the Windows-specific patches to the current `next` branch. An identical fix was suggested by John Keeping.

2016-08-04t7063: work around FreeBSD's lazy mtime update featureLibravatar Nguyễn Thái Ngọc Duy1-1/+16
Let's start with the commit message of [1] from freebsd.git [2] Sync timestamp changes for inodes of special files to disk as late as possible (when the inode is reclaimed). Temporarily only do this if option UFS_LAZYMOD configured and softupdates aren't enabled. UFS_LAZYMOD is intentionally left out of /sys/conf/options. This is mainly to avoid almost useless disk i/o on battery powered machines. It's silly to write to disk (on the next sync or when the inode becomes inactive) just because someone hit a key or something wrote to the screen or /dev/null. PR: 5577 [3] The short version of that, in the context of t7063, is that when a directory is updated, its mtime may be updated later, not immediately. This can be shown with a simple command sequence date; sleep 1; touch abc; rm abc; sleep 10; ls -lTd . One would expect that the date shown in `ls` would be one second from `date`, but it's 10 seconds later. If we put another `ls -lTd .` in front of `sleep 10`, then the date of the last `ls` comes as expected. The first `ls` somehow forces mtime to be updated. t7063 is really sensitive to directory mtime. When mtime is too "new", git code suspects racy timestamps and will not trigger the shortcut in untracked cache, in t7063.24 and eventually be detected in t7063.27 We have two options thanks to this special FreeBSD feature: 1) Stop supporting untracked cache on FreeBSD. Skip t7063 entirely when running on FreeBSD 2) Work around this problem (using the same 'ls' trick) and continue to support untracked cache on FreeBSD I initially wanted to go with 1) because I didn't know the exact nature of this feature and feared that it would make untracked cache work unreliably, using the cached version when it should not. Since the behavior of this thing is clearer now. The picture is not that bad. If this indeed happens often, untracked cache would assume racy condition more often and _fall back_ to non-untracked cache code paths. Which means it may be less effective, but it will not show wrong things. This patch goes with option 2. PS. For those who want to look further in FreeBSD source code, this flag is now called IN_LAZYMOD. I can see it's effective in ext2 and ufs. zfs is not affected.

2016-08-03t4130: work around Windows limitationLibravatar Johannes Sixt1-3/+7
On Windows, it is already pretty expensive to try to recreate the stat() data that Git assumes is cheap to obtain. To make things halfway decent in performance, we even have to skip emulating the inode and to determine the number of hard links. This is not a huge problem, usually, as either the size or the mtime or the ctime are tell-tale enough to say when a file has changed, and even if not, those changes are typically made after the index file was written, triggering a rehashing of the files' contents. The t4130-apply-criss-cross-rename test case, however, requires the inode to determine that files of equal size were swapped, as renaming files does not update their mtime. Every once in a while, t4130 fails on Windows because of this missing piece. Equal file sizes are not crucial for the test cases, however. Hence, generate files with different sizes so that there is some property that the swapped files can be discovered reliably even on Windows.

Commit 959b5455 (submodule: implement a config API for lookup of .gitmodules values, 2015-08-18) implemented the initial version of the submodule config cache. During development of that initial version we extracted the function gitmodule_sha1_from_commit(). During that process we missed that the strbuf rev was still used in config_from() and now is left empty. Lets fix this by also returning this string.

The documentation claims that "raw-local" does not work. It does, but the end result is rather subtle. Let's describe it in better detail, and test to make sure it works (namely, the epoch time doesn't change, but the zone does). While we are rewording the documentation in this area, let's not use the phrase "does not work" for the remaining option, "--date=relative". It's vague; do we accept it or not? We do accept it, but it has no effect (which is a reasonable outcome). We should also refer to the option not as "--relative" (which is the historical synonym, and does not take "-local" at all), but as "--date=relative".

2016-07-27t4205: indent here documentsLibravatar Jeff King1-196/+196
Our usual style in the test scripts is to indent here documents with tabs, and use "<<-" to strip the tabs. The result is easier to read. This old test script did not do so in its inception, and further tests added onto it followed the local style. Let's bring it in line with our usual style. Some of the tests actually care quite a bit about whitespace, but none of them do so at the beginning of the line (because they use things like qz_to_tab_space to avoid depending on the literal whitespace), so we can do a fairly mechanical conversion. Most of the here-docs also use interpolation, so they have been left as "<<-EOF". In a few cases, though, where interpolation was not in use, I've converted them to "<<-\EOF" to match our usual "don't interpolate unless you need to" style.

The test currently does something like: do_one() && do_two() && test_expect_success ... We generally avoid performing actions at the top-level of the script (outside of a test_expect block) for two reasons: 1. The test harness is not checking and reporting if they fail. 2. Their output is not handled correctly (not hidden by default, nor shown with "-v"). Using &&-chains seems like it should help with (1), but it doesn't. If either of the commands fails, we simply skip running the follow-on test entirely, and the test harness has no idea. We can fix this by pushing that setup into its own block. It _could_ go into the following test block, but since the result in this case is used by multiple tests, it's more clear to mark it explicitly as a distinct setup step.

When c5c31d33 (grep: move pattern-type bits support to top-level grep.[ch], 2012-10-03) introduced grep_commit_pattern_type() helper function, the intention was to allow the users of grep API to having to fiddle only with .pattern_type_option (which can be set to "fixed", "basic", "extended", and "pcre"), and then immediately before compiling the pattern strings for use, call grep_commit_pattern_type() to have it prepare various bits in the grep_opt structure (like .fixed, .regflags, etc.). However, grep_set_pattern_type_option() helper function the grep API internally uses were left as an external function by mistake. This function shouldn't have been made callable by the users of the API. Later when the grep API was used in revision traversal machinery, the caller then mistakenly started calling the function around 34a4ae55 (log --grep: use the same helper to set -E/-F options as "git grep", 2012-10-03), instead of setting the .pattern_type_option field and letting the grep_commit_pattern_type() to take care of the details. This caused an unnecessary bug that made a configured grep.patternType take precedence over the command line options (e.g. --basic-regexp, --fixed-strings) in "git log" family of commands.

2016-07-22diff: do not reuse worktree files that need "clean" conversionLibravatar Jeff King1-0/+11
When accessing a blob for a diff, we may try to reuse file contents in the working tree, under the theory that it is faster to mmap those file contents than it would be to extract the content from the object database. When we have to filter those contents, though, that assumption does not hold. Even for our internal conversions like CRLF, we have to allocate and fill a new buffer anyway. But much worse, for external clean filters we have to exec an arbitrary script, and we have no idea how expensive it may be to run. So let's skip this optimization when conversion into git's "clean" form is required. This applies whenever the "want_file" flag is false. When it's true, the caller actually wants the smudged worktree contents, which the reused file by definition already has (in fact, this is a key optimization going the other direction, since reusing the worktree file there lets us skip smudge filters).

2016-07-22status: suggest 'git merge --abort' when appropriateLibravatar Matthieu Moy2-0/+5
We already suggest 'git rebase --abort' during a conflicted rebase. Similarly, suggest 'git merge --abort' during conflict resolution on 'git merge'. Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-07-20t5541: fix url scrubbing test when GPG is not setLibravatar Jeff King1-2/+4
When the GPG prereq is not set, we do not run test 34. That test changes the directory of the test script as a side effect (something we usually frown on, but which matches the style of the rest of this script). When test 35 (the url-scrubbing test) runs, it expects to be in the directory from test 34. If it's not, the test fails; we are in a different sub-repo, our test-commit is built on a different history, and the push becomes a non-fast-forward. We can fix this by unconditionally moving to the directory we expect (again, against our usual style but matching how the rest of the script operates). As an additional protection, let's also switch from "make a new commit and push to master" to just "push to a new branch". We don't care about the branch name; we just want _some_ ref update to trigger the status output. Pushing to a new branch is less likely to run into problems with force-updates, changing the checked-out branch, etc. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-07-18t/t8003-blame-corner-cases.sh: Use here documentsLibravatar Mike Hommey1-17/+17
Somehow, this test was using: { echo A echo B } > file block to feed file contents. This changes those to the form most common in git test scripts: cat >file <<-\EOF A B EOF Signed-off-by: Mike Hommey <mh@glandium.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-07-18blame: allow to blame paths freshly added to the indexLibravatar Mike Hommey1-0/+45
When blaming files, changes in the work tree are taken into account and displayed as being "Not Committed Yet". However, when blaming a file that is not known to the current HEAD, git blame fails with `no such path 'foo' in HEAD`, even when the file was git add'ed. Allowing such a blame is useful when the new file added to the index (not yet committed) was created by renaming an existing file. It also is useful when the new file was created from pieces already in HEAD, moved or copied from other files and blaming with copy detection (i.e. "-C").
