This was done by assigning the mode = WORKING_DIRECTORY to the files inside a moved directory. submodules however need to update their link to the git directory as well as updates to the .gitmodules file. By removing the condition of `mode != INDEX` (the remaining modes are BOTH and WORKING_DIRECTORY) for the required submodule actions, we perform these for submodules in a moved directory.

In `submodule update` we make a call to `submodule--helper list --prefix "$wt_prefix"` which looks a bit brittle and likely to introduce a bug for the path handling. It is not a bug as the prefix is ignored inside the submodule helper for now. If this test breaks eventually, we want to make sure the `wt_prefix` is passed correctly into recursive submodules. Hint: In recursive submodules we expect `wt_prefix` to be empty. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The new test demonstrates a failure in the code prior to this patch. Instead of getting the expected Submodule 'submodule' (${pwd}/submodule) registered for path '../super/submodule' the `super` directory is omitted and you get Submodule 'submodule' (${pwd}/submodule) registered for path '../submodule' instead.

Because the generated script uses $(command substitution), which is not supported by /bin/sh on some platforms (e.g. Solaris), the resulting pre-commit always fails. Which is not noticeable as the test that uses the hook is about checking the behaviour of the command when the hook fails ;-), but nevertheless it is not testing what we wanted to test. Use write_script so that the resulting script is run under the same shell our scripted Porcelain commands are run, which must support the necessary $(construct).

The output from the latter is compared with an expected output, again prepared with "printf" hence lacking the final LF. There is no reason for this test to be using files with an incomplete line at the end, and these look more like a mistake of not using printf "%s\n" "string to be written" and using printf "string to be written" Depending on what would be in $GIT_PREFIX, using the latter form could be a bug waiting to happen. Correct them. Also, the test uses hardcoded #!/bin/sh to create a small helper script. For a small task like what the generated script does, it does not matter too much in that what appears as /bin/sh would not be _so_ broken, but while we are at it, use write_script instead, which happens to make the result easier to read by reducing need of one level of quoting.

This matches our normal shell style, which is good. But it also breaks the test on Solaris, where /bin/sh does not understand $(). Our normal shell style assumes a modern-ish shell which knows about $(). However, some tests create small helper scripts and just write "#!/bin/sh" into them. These scripts either need to go back to using backticks, or they need to respect $SHELL_PATH. The easiest way to do the latter is to use write_script. While we're at it, let's also stick the script creation inside a test_expect block (our usual style), and split the perl snippet into its own script (to prevent quoting madness).

Later, we noticed one breakage from this change and corrected it with 25206778 (commit: don't start editor if empty message is given with -m, 2013-05-25). However, "we got a message with -m, even though an empty one, so we shouldn't be launching an editor" was not the only breakage. * "git commit --amend -m '' --allow-empty", even though it looks strange, is a valid request to amend the commit to have no message at all. Due to the misdetection of the presence of -m on the command line, we ended up keeping the log messsage from the original commit. * "git commit -m "$msg" -F file" should be rejected whether $msg is an empty string or not, but due to the same bug, was not rejected when $msg is empty. * "git -c template=file -m "$msg"" should ignore the template even when $msg is empty, but it didn't and instead used the contents from the template file. Correct these by checking have_option_m, which the earlier 25206778 introduced to fix the same bug.

It always skips past "refs/remotes/", instead of skipping past the prefix associated with the branch we are showing (so commonly we see "refs/remotes/" for the refs/remotes/origin/HEAD symref, but the previous code would skip "refs/heads/" when showing a symref it found in refs/heads/. 2. If skip_prefix() does not match, it leaves "desc" untouched, and we show whatever happened to be in it (which is the refname from a call to skip_prefix() earlier in the function). 3. If we do match with skip_prefix(), we stomp on the "desc" variable, which is later passed to add_verbose_info(). We probably want to retain the original refname there (though it likely doesn't matter in practice, since after all, one points to the other). The fix to match the original code is fairly easy: record the prefix to strip based on item->kind, and use it here. However, since we already have a local variable named "prefix", let's give the two prefixes verbose names so we don't confuse them.

This makes the check for refspecs not being NULL to always return true, which, in conjunction with the check for --all or --mirror options, is always true as well and returns usage message instead of proceeding.

This behavior is a side effect of commit v2.0.0-rc4~8^2~14 (diffcore-rename.c: simplify finding exact renames, 2013-11-14): the hashmap storing sources returns entries from the same bucket, i.e. sources matching the current destination, in LIFO order. Thus the iteration first examines 'other-dir/A/file' and 'dir/B/file' and, upon finding identical content and basename, reports an exact rename. Other hashmap users are apparently happy with the current iteration order over the entries of a bucket. Changing the iteration order would risk upsetting other hashmap users and would increase the memory footprint of each bucket by a pointer to the tail element. Fill the hashmap with source entries in reverse order to restore the original exact rename detection behavior.

However, because we use fill_directory() to do the recursion, it will skip over any directories which look like sub-repositories. For a normal git operation (like "git grep" in a repository) this makes sense; we do not want to cross the boundary out of our current repository into a submodule. But for "--no-index" without a repository, we should look at all files, including embedded repositories. There is one exception, though: we probably should _not_ descend into ".git" directories. Doing so is inefficient and unlikely to turn up useful hits. This patch drops our use of dir.c's gitlink-detection, but we do still avoid ".git". That makes us more like tools such as "ack" or "ag", which also know to avoid cruft in .git. As a bonus, this also drops our usage of the ref code when we are outside of a repository, making the transition to pluggable ref backends cleaner.

One of the uses of this data is for functions to behave appropriately based on whether we are in a repo. But the startup_info struct is just a pointer to storage provided by the main program, and the only program that sets it up is the git.c wrapper. Thus builtins have access to startup_info, but externally linked programs do not. Worse, library code which is accessible from both has to be careful about accessing startup_info. This can be used to trigger a die("BUG") via get_sha1(): $ git fast-import <<-\EOF tag foo from HEAD:./whatever EOF fatal: BUG: startup_info struct is not initialized. Obviously that's fairly nonsensical input to feed to fast-import, but we should never hit a die("BUG"). And there may be other ways to trigger it if other non-builtins resolve sha1s. So let's point the storage for startup_info to a static variable in setup.c, making it available to all users of the library code. We _could_ turn startup_info into a regular extern struct, but doing so would mean tweaking all of the existing use sites. So let's leave the pointer indirection in place. We can, however, drop any checks for NULL, as they will always be false (and likewise, we can drop the test covering this case, which was a rather artificial situation using one of the test-* programs).

After getdelim() returns -1, we re-initialize the strbuf only if sb->buf is NULL. The thinking was that either: 1. We fed an existing allocated buffer to getdelim(), and at most it would have realloc'd, leaving our NUL in place. 2. We didn't have a buffer to feed, so we gave getdelim() NULL; sb->buf will remain NULL, and we just want to restore the empty slopbuf. But that second case isn't quite right. getdelim() may allocate a buffer, write nothing into it, and then return EOF. The resulting strbuf rightfully has sb->len set to "0", but is missing the NUL terminator in the first byte. Most call-sites are fine with this. They see the EOF and don't bother looking at the strbuf. Or they notice that sb->len is empty, and don't look at the contents. But there's at least one case that does neither, and relies on parsing the resulting (possibly zero-length) string: fast-import. You can see this in action with the new test (though we probably only notice failure there when run with --valgrind or ASAN). We can fix this by unconditionally resetting the strbuf when we have a buffer after getdelim(). That fixes case 2 above. Case 1 is probably already fine in practice, but it does not hurt for us to re-assert our invariants (especially because we are relying on whatever getdelim() happens to do, which may vary from platform to platform). Our fix covers that case, too. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
