We `cat` files, but don't inspect or grab the contents in any way.
Unlike in an earlier commit, there is no reason to suspect that these
files could be missing, so `cat`-ing them is just wasted effort.

To prevent long blocking time during a 'git fetch' call, a user
may want to set up a schedule for background 'git fetch' processes.
However, these runs will update the refs/remotes branches due to
the default refspec set in the config when Git adds a remote.
Hence the user will not notice when remote refs are updated during
their foreground fetches. In fact, they may _want_ those refs to
stay put so they can work with the refs from their last foreground
fetch call.
This can be accomplished by overriding the configured refspec using
'--refmap=' along with a custom refspec:
git fetch --refmap='' <remote> +refs/heads/*:refs/hidden/<remote>/*
to populate a custom ref space and download a pack of the new
reachable objects. This kind of call allows a few things to happen:
1. We download a new pack if refs have updated.
2. Since the refs/hidden branches exist, GC will not remove the
newly-downloaded data.
3. With fetch.writeCommitGraph enabled, the refs/hidden refs are
used to update the commit-graph file.
To avoid the refs/hidden directory from filling without bound, the
--prune option can be included. When providing a refspec like this,
the --prune option does not delete remote refs and instead only
deletes refs in the target refspace.
Update the documentation to clarify how '--refmap=""' works and
create tests to guarantee this behavior remains in the future.

Regression fix.
* ds/commit-graph-on-fetch:
commit-graph: fix writing first commit-graph during fetch
t5510-fetch.sh: demonstrate fetch.writeCommitGraph bug
|
|
The previous commit includes a failing test for an issue around
fetch.writeCommitGraph and fetching in a repo with a submodule. Here, we
fix that bug and set the test to "test_expect_success".
The problem arises with this set of commands when the remote repo at
<url> has a submodule. Note that --recurse-submodules is not needed to
demonstrate the bug.
$ git clone <url> test
$ cd test
$ git -c fetch.writeCommitGraph=true fetch origin
Computing commit graph generation numbers: 100% (12/12), done.
BUG: commit-graph.c:886: missing parent <hash1> for commit <hash2>
Aborted (core dumped)
As an initial fix, I converted the code in builtin/fetch.c that calls
write_commit_graph_reachable() to instead launch a "git commit-graph
write --reachable --split" process. That code worked, but is not how we
want the feature to work long-term.
That test did demonstrate that the issue must be something to do with
internal state of the 'git fetch' process.
The write_commit_graph() method in commit-graph.c ensures the commits we
plan to write are "closed under reachability" using close_reachable().
This method walks from the input commits, and uses the UNINTERESTING
flag to mark which commits have already been visited. This allows the
walk to take O(N) time, where N is the number of commits, instead of
O(P) time, where P is the number of paths. (The number of paths can be
exponential in the number of commits.)
However, the UNINTERESTING flag is used in lots of places in the
codebase. This flag usually means some barrier to stop a commit walk,
such as in revision-walking to compare histories. It is not often
cleared after the walk completes because the starting points of those
walks do not have the UNINTERESTING flag, and clear_commit_marks() would
stop immediately.
This is happening during a 'git fetch' call with a remote. The fetch
negotiation is comparing the remote refs with the local refs and marking
some commits as UNINTERESTING.
I tested running clear_commit_marks_many() to clear the UNINTERESTING
flag inside close_reachable(), but the tips did not have the flag, so
that did nothing.
It turns out that the calculate_changed_submodule_paths() method is at
fault. Thanks, Peff, for pointing out this detail! More specifically,
for each submodule, the collect_changed_submodules() runs a revision
walk to essentially do file-history on the list of submodules. That
revision walk marks commits UNININTERESTING if they are simplified away
by not changing the submodule.
Instead, I finally arrived on the conclusion that I should use a flag
that is not used in any other part of the code. In commit-reach.c, a
number of flags were defined for commit walk algorithms. The REACHABLE
flag seemed like it made the most sense, and it seems it was not
actually used in the file. The REACHABLE flag was used in early versions
of commit-reach.c, but was removed by 4fbcca4 (commit-reach: make
can_all_from_reach... linear, 2018-07-20).
Add the REACHABLE flag to commit-graph.c and use it instead of
UNINTERESTING in close_reachable(). This fixes the bug in manual
testing.

While dogfooding, Johannes found a bug in the fetch.writeCommitGraph
config behavior. His example initially happened during a clone with
--recurse-submodules, we found that this happens with the first fetch
after cloning a repository that contains a submodule:
$ git clone <url> test
$ cd test
$ git -c fetch.writeCommitGraph=true fetch origin
Computing commit graph generation numbers: 100% (12/12), done.
BUG: commit-graph.c:886: missing parent <hash1> for commit <hash2>
Aborted (core dumped)
In the repo I had cloned, there were really 60 commits to scan, but
only 12 were in the list to write when calling
compute_generation_numbers(). A commit in the list expects to see a
parent, but that parent is not in the list.
A follow-up will fix the bug, but first we create a test that
demonstrates the problem. This test must be careful about an existing
commit-graph file, since GIT_TEST_COMMIT_GRAPH=1 will cause the repo we
are cloning to already have one. This then prevents the incremtnal
commit-graph write during the first 'git fetch'.

A configuration variable tells "git fetch" to write the commit
graph after finishing.
* ds/commit-graph-on-fetch:
fetch: add fetch.writeCommitGraph config setting
|
|
The commit-graph feature is now on by default, and is being
written during 'git gc' by default. Typically, Git only writes
a commit-graph when a 'git gc --auto' command passes the gc.auto
setting to actualy do work. This means that a commit-graph will
typically fall behind the commits that are being used every day.
To stay updated with the latest commits, add a step to 'git
fetch' to write a commit-graph after fetching new objects. The
fetch.writeCommitGraph config setting enables writing a split
commit-graph, so on average the cost of writing this file is
very small. Occasionally, the commit-graph chain will collapse
to a single level, and this could be slow for very large repos.
For additional use, adjust the default to be true when
feature.experimental is enabled.

't5510-fetch.sh' sources 'lib-httpd.sh' near the end to run a
httpd-specific test, but 'lib-httpd.sh' skips all the rest of the test
script if the dependencies for running httpd tests are not fulfilled.
Alas, recently cdbd70c437 (fetch: add --[no-]show-forced-updates
argument, 2019-06-18) appended a non-httpd-specific test at the end,
and this test is then skipped as well when httpd tests can't be run.
Move this new test earlier in the test script, before 'lib-httpd.sh'
is sourced, so it will be run even when httpd tests aren't.
Also add a comment at the end of this test script to warn against
adding non-httpd-specific tests at the end, in the hope that it will
help prevent similar issues in the future.

The test '--no-show-forced-updates' in 't5510-fetch.sh' added in
cdbd70c437 (fetch: add --[no-]show-forced-updates argument,
2019-06-18) runs '! test_i18ngrep ...'. This is wrong, because when
running the test with GIT_TEST_GETTEXT_POISON=true, then
'test_i18ngrep' is basically a noop and always returns with success,
the leading ! turns that into a failure, which then fails the test.
Use 'test_i18ngrep ! ...' instead.
This went unnoticed by our GETTEXT_POISON CI builds, because those
builds don't run this test case: in those builds we don't install
Apache, and this test comes after 't5510' sources 'lib-httpd.sh',
which, consequently, skips all the remaining tests, including this
one.

After updating a set of remove refs during a 'git fetch', we walk the
commits in the new ref value and not in the old ref value to discover
if the update was a forced update. This results in two things happening
during the command:
1. The line including the ref update has an additional "(forced-update)"
marker at the end.
2. The ref log for that remote branch includes a bit saying that update
is a forced update.
For many situations, this forced-update message happens infrequently, or
is a small bit of information among many ref updates. Many users ignore
these messages, but the calculation required here slows down their fetches
significantly. Keep in mind that they do not have the opportunity to
calculate a commit-graph file containing the newly-fetched commits, so
these comparisons can be very slow.
Add a '--[no-]show-forced-updates' option that allows a user to skip this
calculation. The only permanent result is dropping the forced-update bit
in the reflog.
Include a new fetch.showForcedUpdates config setting that allows this
behavior without including the argument in every command. The config
setting is overridden by the command-line arguments.

"git gc --auto" opens file descriptors for the packfiles before

When matching a non-wildcard LHS of a refspec against a list of
refs, find_ref_by_name_abbrev() returns the first ref that matches
using any DWIM rules used by refname_match() in refs.c, even if a
better match occurs later in the list of refs.
This causes unexpected behavior when (for example) fetching using
the refspec "refs/heads/s:<something>" from a remote with both
"refs/heads/refs/heads/s" and "refs/heads/s"; even if the former was
inadvertently created, one would still expect the latter to be
fetched. Similarly, when both a tag T and a branch T exist,
fetching T should favor the tag, just like how local refname
disambiguation rule works. But because the code walks over
ls-remote output from the remote, which happens to be sorted in
alphabetical order and has refs/heads/T before refs/tags/T, a
request to fetch T is (mis)interpreted as fetching refs/heads/T.
Update refname_match(), all of whose current callers care only if it
returns non-zero (i.e. matches) to see if an abbreviated name can
mean the full name being tested, so that it returns a positive
integer whose magnitude can be used to tell the precedence, and fix
the find_ref_by_name_abbrev() function not to stop at the first
match but find the match with the highest precedence.
This is based on an earlier work, which special cased only the exact
matches, by Jonathan Tan.

During negotiation, fetch-pack eventually reports as "have" lines all
commits reachable from all refs. Allow the user to restrict the commits
sent in this way by providing a whitelist of tips; only the tips
themselves and their ancestors will be sent.
Both globs and single objects are supported.
This feature is only supported for protocols that support connect or
stateless-connect (such as HTTP with protocol v2).
This will speed up negotiation when the repository has multiple
relatively independent branches (for example, when a repository
interacts with multiple repositories, such as with linux-next [1] and
torvalds/linux [2]), and the user knows which local branch is likely to
have commits in common with the upstream branch they are fetching.

Quite a many tests assumed that newly created refs are made as
loose refs using the files backend, which have been updated to use
proper plumbing like rev-parse and update-ref, to avoid breakage
once we start using different ref backends.
* cc/tests-without-assuming-ref-files-backend:

t: make many tests depend less on the refs being files
|

Many tests are very focused on the file system representation of the
loose and packed refs code. As there are plans to implement other
ref storage systems, let's migrate these tests to a form that test
the intent of the refs storage system instead of it internals.
This will make clear to readers that these tests do not depend on
which ref backend is used.
The internals of the loose refs backend are still tested in
t1400-update-ref.sh, whereas the tests changed in this patch focus
on testing other aspects.
This patch just takes care of many low hanging fruits. It does not
try to completely solves the issue.

Add a --prune-tags option to git-fetch, along with fetch.pruneTags
config option and a -P shorthand (-p is --prune). This allows for
doing any of:
git fetch -p -P
git fetch --prune --prune-tags
git fetch -p -P origin
git fetch --prune --prune-tags origin
Or simply:
git config fetch.prune true &&
git config fetch.pruneTags true &&
git fetch
Instead of the much more verbose:
git fetch --prune origin 'refs/tags/*:refs/tags/*' '+refs/heads/*:refs/remotes/origin/*'
Before this feature it was painful to support the use-case of pulling
from a repo which is having both its branches *and* tags deleted
regularly, and have our local references to reflect upstream.
At work we create deployment tags in the repo for each rollout, and
there's *lots* of those, so they're archived within weeks for
performance reasons.
Without this change it's hard to centrally configure such repos in
/etc/gitconfig (on servers that are only used for working with
them). You need to set fetch.prune=true globally, and then for each
repo:
git -C {} config --replace-all remote.origin.fetch "refs/tags/*:refs/tags/*" "^\+*refs/tags/\*:refs/tags/\*$"
Now I can simply set fetch.pruneTags=true in /etc/gitconfig as well,
and users running "git pull" will automatically get the pruning
semantics I want.
Even though "git remote" has corresponding "prune" and "update
--prune" subcommands I'm intentionally not adding a corresponding
prune-tags or "update --prune --prune-tags" mode to that command.
It's advertised (as noted in my recent "git remote doc: correct
dangerous lies about what prune does") as only modifying remote
tracking references, whereas any --prune-tags option is always going
to modify what from the user's perspective is a local copy of the tag,
since there's no such thing as a remote tracking tag.
Ideally add_prune_tags_to_fetch_refspec() would be something that
would use ALLOC_GROW() to grow the 'fetch` member of the 'remote'
struct. Instead I'm realloc-ing remote->fetch and adding the
tag_refspec to the end.
The reason is that parse_{fetch,push}_refspec which allocate the
refspec (ultimately remote->fetch) struct are called many places that
don't have access to a 'remote' struct. It would be hard to change all
their callsites to be amenable to carry around the bookkeeping
variables required for dynamic allocation.
All the other callers of the API first incrementally construct the
string version of the refspec in remote->fetch_refspec via
add_fetch_refspec(), before finally calling parse_fetch_refspec() via
some variation of remote_get().
It's less of a pain to deal with the one special case that needs to
modify already constructed refspecs than to chase down and change all
the other callsites. The API I'm adding is intentionally not
generalized because if we add more of these we'd probably want to
re-visit how this is done.

When a remote URL is supplied on the command-line the internals of the
fetch are different, in particular the code in get_ref_map(). An
earlier version of the subsequent fetch.pruneTags patch hid a segfault
because the difference wasn't tested for.
Now all the tests are run as both of the variants of:
git fetch
git -c [...] fetch $(git config remote.origin.url) $(git config remote.origin.fetch)
I'm using -c because while the [fetch] config just set by
set_config_tristate will be picked up, the remote.origin.* config
won't override it as intended.
Work around that and turn this into a purely command-line test by
always setting the variables on the command-line, and translate any
setting of remote.origin.X into fetch.X.
The reason for choosing the names "name" and "link" as opposed to
e.g. "named" and "url" is because they're the same length, which makes
the test output easier to read as it will be aligned.
Due to shellscript quoting madness it's not worthwhile to do all of
this within a test_expect_success, but do the parts that can easily be
done there, including the one-time setting of variables that don't
change between runs to be used by subsequent runs in the 'prune_type
setup' test.

One of the tests in 't5510-fetch.sh' checks the output of 'git fetch'
using 'test_i18ngrep', and while doing so it prefilters the output
with 'grep' before piping the result into 'test_i18ngrep'.
This prefiltering is unnecessary, with the appropriate pattern
'test_i18ngrep' can do it all by itself. Furthermore, piping data

added in a later patch.

Hotfix of a test in a topic that has already been merged to 'master'.
* nd/fetch-ref-summary:
t5510: skip tests under GETTEXT_POISON build
|
|
Skip tests when running under GETTEXT_POISON build and run them with
C_LOCALE_OUTPUT prerequisite.
These tests are irrelevant under GETTEXT_POISON because they test text
output alignment which GETTEXT_POISON turns useless.

Improve the look of the way "git fetch" reports what happened to
each ref that was fetched.
* nd/fetch-ref-summary:
fetch: reduce duplicate in ref update status lines with placeholder
fetch: align all "remote -> local" output
fetch: change flag code for displaying tag update and deleted ref
fetch: refactor ref update status formatting code
git-fetch.txt: document fetch output
|
|
In the "remote -> local" line, if either ref is a substring of the
other, the common part in the other string is replaced with "*". For
example
abc -> origin/abc
refs/pull/123/head -> pull/123
become
abc -> origin/*
refs/*/head -> pull/123
Activated with fetch.output=compact.
For the record, this output is not perfect. A single giant ref can
push all refs very far to the right and likely be wrapped around. We
may have a few options:
- exclude these long lines smarter
- break the line after "->", exclude it from column width calculation
- implement a new format, { -> origin/}foo, which makes the problem
go away at the cost of a bit harder to read
- reverse all the arrows so we have "* <- looong-ref", again still
hard to read.

We do align "remote -> local" output by allocating 10 columns to
"remote". That produces aligned output only for short refs. An extra
pass is performed to find the longest remote ref name (that does not
produce a line longer than terminal width) to produce better aligned
output.

The test functions test_i18ncmp and test_i18ngrep pretend success if run
under GETTEXT_POISON. By using those functions to test output which is
correctly marked as translatable, enables one to detect if the strings
newly marked for translation are from plumbing output. If they are
indeed from plumbing, the test would fail, and the string should be
unmarked, since it is not seen by users.
Thus, it is productive to not have false positives when running the test
under GETTEXT_POISON. This commit replaces normal test functions by
their i18n aware variants in use-cases know to be correctly marked for
translation, suppressing false positives.

* js/close-packs-before-gc:
t5510: run auto-gc in the foreground
|
|
The last test added to 't5510-fetch' in 0898c9628104 (fetch: release
pack files before garbage-collecting, 2016-01-13) may sporadically
trigger following error message from the test harness:
rm: cannot remove 'trash directory.t5510-fetch/auto-gc/.git': Directory not empty
The test in question forces an auto-gc, which, if the system supports
it, runs in the background by default, and occasionally takes long
enough for the test to finish and for 'test_done' to start
housekeeping. This can lead to the test's 'git gc --auto' in the
background and 'test_done's 'rm -rf $trash' in the foreground racing
each other to create and delete files and directories. It might just
happen that 'git gc' re-creates a directory that 'rm -rf' already
visited and removed, which ultimately triggers the above error.
Disable detaching the auto-gc process to ensure that it finishes
before the test can continue, thus avoiding this racy situation.

A small future-proofing of a test added recently.
* js/close-packs-before-gc:
t5510: do not leave changed cwd
|
|
t5510 carefully keeps the cwd at the test root by using either subshells
or explicit cd'ing back to the root. Use a subshell for the last
subtest, too.

It turns out "git clone" over rsync transport has been broken when
the source repository has packed references for a long time, and
nobody noticed nor complained about it.
* jk/drop-rsync-transport:
transport: drop support for git-over-rsync
|
|
The git-over-rsync protocol is inefficient and broken, and
has been for a long time. It transfers way more objects than
it needs (grabbing all of the remote's "objects/",
regardless of which objects we need). It does its own ad-hoc
parsing of loose and packed refs from the remote, but
doesn't properly override packed refs with loose ones,
leading to garbage results (e.g., expecting the other side
to have an object pointed to by a stale packed-refs entry,
or complaining that the other side has two copies of the
refs[1]).
This latter breakage means that nobody could have
successfully pulled from a moderately active repository
since cd547b4 (fetch/push: readd rsync support, 2007-10-01).
We never made an official deprecation notice in the release
notes for git's rsync protocol, but the tutorial has marked
it as such since 914328a (Update tutorial., 2005-08-30).
And on the mailing list as far back as Oct 2005, we can find
Junio mentioning it as having "been deprecated for quite
some time."[2,3,4]. So it was old news then; cogito had
deprecated the transport in July of 2005[5] (though it did
come back briefly when Linus broke git-http-pull!).
Of course some people professed their love of rsync through
2006, but Linus clarified in his usual gentle manner[6]:
> Thanks! This is why I still use rsync, even though
> everybody and their mother tells me "Linus says rsync is
> deprecated."
No. You're using rsync because you're actively doing
something _wrong_.
The deprecation sentiment was reinforced in 2008, with a
mention that cloning via rsync is broken (with no fix)[7].
Even the commit porting rsync over to C from shell (cd547b4)
lists it as deprecated! So between the 10 years of informal
warnings, and the fact that it has been severely broken
since 2007, it's probably safe to simply remove it without
further deprecation warnings.

Many codepaths that run "gc --auto" before exiting kept packfiles
mapped and left the file descriptors to them open, which was not
friendly to systems that cannot remove files that are open. They
now close the packs before doing so.
