Some tests need to create a string of commits. Doing this with
test_commit is very heavy-weight, as it needs at least one process per
commit (and in fact, uses several).
For bulk creation, we can do much better by using fast-import, but it's
often a pain to generate the input. Let's provide a helper to do so.
We'll use t5310 as a guinea pig, as it has three 10-commit loops. Here
are hyperfine results before and after:
[before]
Benchmark #1: ./t5310-pack-bitmaps.sh --root=/var/ram/git-tests
Time (mean ± σ): 2.846 s ± 0.305 s [User: 3.042 s, System: 0.919 s]
Range (min … max): 2.250 s … 3.210 s 10 runs
[after]
Benchmark #1: ./t5310-pack-bitmaps.sh --root=/var/ram/git-tests
Time (mean ± σ): 2.210 s ± 0.174 s [User: 2.570 s, System: 0.604 s]
Range (min … max): 1.999 s … 2.590 s 10 runs
So we're over 20% faster, while making the callers slightly shorter. We
added a lot more lines in test-lib-function.sh, of course, and the
helper is way more featureful than we need here. But my hope is that it
will be flexible enough to use in more places.

When fetching into a partial clone, Git first prefetches missing
REF_DELTA bases from the promisor remote. (This feature was introduced
in [1].) But as can be seen in a recent test coverage report [2], the
case in which a REF_DELTA base is already present is not covered by
tests.
Extend the tests slightly to cover this case.

Recent code restructuring of merge-recursive engine introduced a
regression dealing with rename/add conflict.
* en/merge-directory-renames-fix:
merge-recursive: restore accidentally dropped setting of path
|
|
In commit 8daec1df03de ("merge-recursive: switch from (oid,mode) pairs
to a diff_filespec", 2019-04-05), we actually switched from
(oid,mode,path) triplets to a diff_filespec -- but most callsites in the
patch only needed to worry about oid and mode so the commit message
focused on that. The oversight in the commit message apparently spilled
over to the code as well; one of the dozen or so callsites accidentally
dropped the setting of the path in the conversion. Restore the path
setting in that location.
Also, this pointed out that our testsuite was lacking a good rename/add
test, at least one that involved the need for merge content with the
rename. Add such a test, and since rename/add vs. add/rename could
possibly be important, redo the merge the opposite direction to make
sure we don't have issues with the direction of the merge. These
testcases failed before restoring the setting of path, but with the
paths appropriately set the testcases both pass.

If someone wants to use as a filter a sparse file that is in the
repository, something like "--filter=sparse:oid=<ref>:<path>"
already works.
So 'sparse:path' is only interesting if the sparse file is not in
the repository. In this case though the current implementation has
a big security issue, as it makes it possible to ask the server to
read any file, like for example /etc/password, and to explore the
filesystem, as well as individual lines of files.
If someone is interested in using a sparse file that is not in the
repository as a filter, then at the minimum a config option, such
as "uploadpack.sparsePathFilter", should be implemented first to
restrict the directory from which the files specified by
'sparse:path' can be read.
For now though, let's just disable 'sparse:path' filters.

Before d473e2e0e8 (diff.c: convert -U|--unified, 2019-01-27), -U and
--unified are implemented with a custom parser opt_arg() in diff.c. I
didn't check this code carefully and not realize that it's the
equivalent of PARSE_OPT_NONEG | PARSE_OPT_OPTARG.
In other words, if -U is specified without any argument, the option
should be accepted, and the default value should be used. Without
PARSE_OPT_OPTARG, parse_options() will reject this case and cause a
regression.

Fix a regression in my recent 3494dfd3ee ("send-email: do defaults ->
config -> getopt in that order", 2019-05-09). I missed that the
$identity variable needs to be extracted from the command-line before
we do the config reading, as it determines which config variable we
should read first. See [1] for the report.
The sendemail.identity feature was added back in
34cc60ce2b ("send-email: Add support for SSL and SMTP-AUTH",
2007-09-03), there were no tests to assert that it worked properly.
So let's fix both the regression, and add some tests to assert that
this is being parsed properly. While I'm at it I'm adding a
--no-identity option to go with --[to|cc|bcc] variable, since the
semantics are similar. It's like to/cc/bcc except that unlike those we
don't support multiple identities, but we could now easily add it
support for it if anyone cares.
In just fixing the --identity command-line parsing bug I discovered
that a narrow fix to that wouldn't do. In read_config() we had a state
machine that would only set config values if they weren't set already,
and thus by proxy we wouldn't e.g. set "to" based on sendemail.to if
we'd seen sendemail.gmail.to before, with --identity=gmail.
I'd modified some of the relevant code in 3494dfd3ee, but just
reverting to that wouldn't do, since it would bring back the
regression fixed in that commit.
Refactor read_config() do what we actually mean here. We don't want to
set a given sendemail.VAR if a sendemail.$identity.VAR previously set
it. The old code was conflating this desire with the hardcoded
defaults for these variables, and as discussed in 3494dfd3ee that was
never going to work. Instead pass along the state of whether an
identity config set something before, as distinguished from the state
of the default just being false, or the default being a non-bool or
true (e.g. --transferencoding).
I'm still not happy with the test coverage here, e.g. there's nothing
testing sendemail.smtpEncryption, but I only have so much time to fix
this code.

In some cases, git request-pull might be invoked with remote and
local objects that differ even though they point to the same commit.
For example, the remote object might be a lightweight tag
vs. an annotated tag on the local side; or the user might have
reworded the tag locally and forgotten to push it.
When this happens git-request-pull will not warn, because it only
checks that "git ls-remote" returns an SHA1 that matches the local
commit (known as $headrev in the script). This patch makes
git-request-pull retrieve the tag object SHA1 while processing
the "git ls-remote" output, so that it can be matched against the
local object.

place, check whether option_commit was enabled by cli when squashing a

Previously, when --squash was supplied, 'option_commit' was silently
dropped. This could have been surprising to a user who tried to override
the no-commit behavior of squash using --commit explicitly.

In --interactive mode, "git am --resolved" will try to generate a patch
based on what is in the index, so that it can prompt "apply this
patch?". To do so it needs the tree of HEAD, which it tries to get with
get_oid_tree(). However, this doesn't yield a tree object; the "tree"
part just means "if you must disambiguate short oids, then prefer trees"
(and we do not need to disambiguate at all, since we are feeding a ref).
Instead, we must parse the oid as a commit (which should always be true
in a non-corrupt repository), and access its tree pointer manually.
This has been broken since the conversion to C in 7ff2683253
(builtin-am: implement -i/--interactive, 2015-08-04), but there was no
test coverage because of interactive-mode's insistence on having a tty.
That was lifted in the previous commit, so we can now add a test for
this case.
Note that before this patch, the test would result in a BUG() which
comes from 3506dc9445 (has_uncommitted_changes(): fall back to empty
tree, 2018-07-11). But before that, we'd have simply segfaulted (and in
fact this is the exact type of case the BUG() added there was trying to
catch!).

For an environment variable that is supposed to be set by users, the
GIT_TR2* env vars are just too unclear, inconsistent, and ugly.
Most of the established GIT_* environment variables don't use
abbreviations, and in case of the few that do (GIT_DIR,
GIT_COMMON_DIR, GIT_DIFF_OPTS) it's quite obvious what the
abbreviations (DIR and OPTS) stand for. But what does TR stand for?
Track, traditional, trailer, transaction, transfer, transformation,
transition, translation, transplant, transport, traversal, tree,
trigger, truncate, trust, or ...?!
The trace2 facility, as the '2' suffix in its name suggests, is
supposed to eventually supercede Git's original trace facility. It's
reasonable to expect that the corresponding environment variables
follow suit, and after the original GIT_TRACE variables they are
called GIT_TRACE2; there is no such thing is 'GIT_TR'.
All trace2-specific config variables are, very sensibly, in the
'trace2' section, not in 'tr2'.
OTOH, we don't gain anything at all by omitting the last three
characters of "trace" from the names of these environment variables.
So let's rename all GIT_TR2* environment variables to GIT_TRACE2*,
before they make their way into a stable release.

Since 7171d8c15f (upload-pack: send symbolic ref information as
capability, 2013-09-17), we've sent cloning and fetching clients special
information about which branch HEAD is pointing to, so that they don't
have to guess based on matching up commit ids.
However, this feature has never worked properly with the GIT_NAMESPACE
feature. Because upload-pack uses head_ref_namespaced(find_symref), we
do find and report on refs/namespaces/foo/HEAD instead of the actual
HEAD of the repo. This makes sense, since the branch pointed to by the
top-level HEAD may not be advertised at all. But we do two things wrong:
1. We report the full name refs/namespaces/foo/HEAD, instead of just
HEAD. Meaning no client is going to bother doing anything with that
symref, since we're not otherwise advertising it.
2. We report the symref destination using its full name (e.g.,
refs/namespaces/foo/refs/heads/master). That's similarly useless to
the client, who only saw "refs/heads/master" in the advertisement.
We should be stripping the namespace prefix off of both places (which
this patch fixes).
Likely nobody noticed because we tend to do the right thing anyway. Bug
(1) means that we said nothing about HEAD (just refs/namespace/foo/HEAD).
And so the client half of the code, from a45b5f0552 (connect: annotate
refs with their symref information in get_remote_head(), 2013-09-17),
does not annotate HEAD, and we use the fallback in guess_remote_head(),
matching refs by object id. Which is usually right. It only falls down
in ambiguous cases, like the one laid out in the included test.
This also means that we don't have to worry about breaking anybody who
was putting pre-stripped names into their namespace symrefs when we fix
bug (2). Because of bug (1), nobody would have been using the symref we
advertised in the first place (not to mention that those symrefs would
have appeared broken for any non-namespaced access).
Note that we have separate fixes here for the v0 and v2 protocols. The
symref advertisement moved in v2 to be a part of the ls-refs command.
This actually gets part (1) right, since the symref annotation
piggy-backs on the existing ref advertisement, which is properly
stripped. But it still needs a fix for part (2). The included tests
cover both protocols.

When using `git clone --recurse-submodules` there was previously no way to
pass a `--remote` switch to the implicit `git submodule update` command for
any use case where you want the submodules to be checked out on their
remote-tracking branch rather than with the SHA-1 recorded in the superproject.
This patch rectifies this situation. It actually passes `--no-fetch` to
`git submodule update` as well on the grounds they the submodule has only just
been cloned, so fetching from the remote again only serves to slow things down.
