Some of the functions in our test library check that they were invoked
properly with conditions like this:
test "$#" = 2 ||
error "bug in the test script: not 2 parameters to test-expect-success"
If this particular condition is triggered, then 'error' will abort the
whole test script with a bold red error message [1] right away.
However, under certain circumstances the test script will be aborted
completely silently, namely if:
- a similar condition in a test helper function like
'test_line_count' is triggered,
- which is invoked from the test script's "main" shell [2],
- and the test script is run manually (i.e. './t1234-foo.sh' as
opposed to 'make t1234-foo.sh' or 'make test') [3]
- and without the '--verbose' option,
because the error message is printed from within 'test_eval_', where
standard output is redirected either to /dev/null or to a log file.
The only indication that something is wrong is that not all tests in
the script are executed and at the end of the test script's output
there is no "# passed all N tests" message, which are subtle and can
easily go unnoticed, as I had to experience myself.
Send these "bug in the test script" error messages directly to the
test scripts standard error and thus to the terminal, so those bugs
will be much harder to overlook. Instead of updating all ~20 such
'error' calls with a redirection, let's add a BUG() function to
'test-lib.sh', wrapping an 'error' call with the proper redirection
and also including the common prefix of those error messages, and
convert all those call sites [4] to use this new BUG() function
instead.
[1] That particular error message from 'test_expect_success' is
printed in color only when running with or without '--verbose';
with '--tee' or '--verbose-log' the error is printed without
color, but it is printed to the terminal nonetheless.
[2] If such a condition is triggered in a subshell of a test, then
'error' won't be able to abort the whole test script, but only the
subshell, which in turn causes the test to fail in the usual way,
indicating loudly and clearly that something is wrong.
[3] Well, 'error' aborts the test script the same way when run
manually or by 'make' or 'prove', but both 'make' and 'prove' pay
attention to the test script's exit status, and even a silently
aborted test script would then trigger those tools' usual
noticable error messages.
[4] Strictly speaking, not all those 'error' calls need that
redirection to send their output to the terminal, see e.g.
'test_expect_success' in the opening example, but I think it's
better to be consistent.

The receive.denyCurrentBranch=updateInstead codepath kicked in even
when the push should have been rejected due to other reasons, such
as it does not fast-forward or the update-hook rejects it, which
has been corrected.
* jc/receive-deny-current-branch-fix:
receive: denyCurrentBranch=updateinstead should not blindly update
|
|
The handling of receive.denyCurrentBranch=updateInstead was added to
a switch statement that handles other values of the variable, but
all the other case arms only checked a condition to reject the
attempted push, or let later logic in the same function to still
intervene, so that a push that does not fast-forward (which is
checked after the switch statement in question) is still rejected.
But the handling of updateInstead incorrectly took immediate effect,
without giving other checks a chance to intervene.
Instead of calling update_worktree() that causes the side effect
immediately, just note the fact that we will need to call the
function later, and first give other checks a chance to reject the
request. After the update-hook gets a chance to reject the push
(which happens as the last step in a series of checks), call
update_worktree() when we earlier detected the need to.

The rules used by "git push" and "git fetch" to determine if a ref
can or cannot be updated were inconsistent; specifically, fetching
to update existing tags were allowed even though tags are supposed
to be unmoving anchoring points. "git fetch" was taught to forbid
updates to existing tags without the "--force" option.
* ab/fetch-tags-noclobber:
fetch: stop clobbering existing tags without --force
fetch: document local ref updates with/without --force
push doc: correct lies about how push refspecs work
push doc: move mention of "tag <tag>" later in the prose
push doc: remove confusing mention of remote merger
fetch tests: add a test for clobbering tag behavior
push tests: use spaces in interpolated string
push tests: make use of unused $1 in test description
fetch: change "branch" to "reference" in --force -h output
|
|
Change "fetch" to treat "+" in refspecs (aka --force) to mean we
should clobber a local tag of the same name.
This changes the long-standing behavior of "fetch" added in
853a3697dc ("[PATCH] Multi-head fetch.", 2005-08-20). Before this
change, all tag fetches effectively had --force enabled. See the
git-fetch-script code in fast_forward_local() with the comment:
> Tags need not be pointing at commits so there is no way to
> guarantee "fast-forward" anyway.
That commit and the rest of the history of "fetch" shows that the
"+" (--force) part of refpecs was only conceived for branch updates,
while tags have accepted any changes from upstream unconditionally and
clobbered the local tag object. Changing this behavior has been
discussed as early as 2011[1].
The current behavior doesn't make sense to me, it easily results in
local tags accidentally being clobbered. We could namespace our tags
per-remote and not locally populate refs/tags/*, but as with my
97716d217c ("fetch: add a --prune-tags option and fetch.pruneTags
config", 2018-02-09) it's easier to work around the current
implementation than to fix the root cause.
So this change implements suggestion #1 from Jeff's 2011 E-Mail[1],
"fetch" now only clobbers the tag if either "+" is provided as part of
the refspec, or if "--force" is provided on the command-line.
This also makes it nicely symmetrical with how "tag" itself works when
creating tags. I.e. we refuse to clobber any existing tags unless
"--force" is supplied. Now we can refuse all such clobbering, whether
it would happen by clobbering a local tag with "tag", or by fetching
it from the remote with "fetch".
Ref updates outside refs/{tags,heads/* are still still not symmetrical
with how "git push" works, as discussed in the recently changed
pull-fetch-param.txt documentation. This change brings the two
divergent behaviors more into line with one another. I don't think
there's any reason "fetch" couldn't fully converge with the behavior
used by "push", but that's a topic for another change.
One of the tests added in 31b808a032 ("clone --single: limit the fetch
refspec to fetched branch", 2012-09-20) is being changed to use
--force where a clone would clobber a tag. This changes nothing about
the existing behavior of the test.

There used to be less exhaustive tests for this with the code added in

Improve the tests added in dbfeddb12e ("push: require force for refs
under refs/tags/", 2012-11-29) to assert that the same behavior
applies various other combinations of command-line option and
refspecs.
Supplying either "+" in refspec or "--force" is sufficient to clobber
the reference. With --no-force we still pay attention to "+" in the
refspec, and vice-versa with clobbering kicking in if there's no "+"
in the refspec but "+" is given.
This is consistent with how refspecs work for branches, where either
"+" or "--force" will enable clobbering, with neither taking priority
over the other.

The intent of this test is to force-create a new tag pointing to

to push the previous tag for the unrelated reason of providing a
refspec that doesn't make any sense.

* bw/ref-prefix-for-configured-refspec:
fetch: do not pass ref-prefixes for fetch by exact SHA1
|
|
When v2.18.0-rc0~10^2~1 (refspec: consolidate ref-prefix generation
logic, 2018-05-16) factored out the ref-prefix generation code for
reuse, it left out the 'if (!item->exact_sha1)' test in the original
ref-prefix generation code. As a result, fetches by SHA-1 generate
ref-prefixes as though the SHA-1 being fetched were an abbreviated ref
name:
$ GIT_TRACE_PACKET=1 bin-wrappers/git -c protocol.version=2 \
fetch origin 12039e008f9a4e3394f3f94f8ea897785cb09448
[...]
packet: fetch> ref-prefix 12039e008f9a4e3394f3f94f8ea897785cb09448
packet: fetch> ref-prefix refs/12039e008f9a4e3394f3f94f8ea897785cb09448

packet: fetch> 0000
If there is another ref name on the command line or the object being
fetched is already available locally, then that's mostly harmless.
But otherwise, we error out with
fatal: no matching remote head
since the server did not send any refs we are interested in. Filter
out the exact_sha1 refspecs to avoid this.
This patch adds a test to check this behavior that notices another
behavior difference between protocol v0 and v2 in the process. Add a
NEEDSWORK comment to clear it up.

In a while-at-it cleanup replacing a 'cd dir && <...> && cd ..' with a
subshell, commit 28391a80a9 (receive-pack: allow deletion of corrupt
refs, 2007-11-29) also moved the assignment of the $old_commit
variable to that subshell. This variable, however, is used outside of
that subshell as a parameter of check_push_result(), to check that a
ref still points to the commit where it is supposed to. With the
variable remaining unset outside the subshell check_push_result()
doesn't perform that check at all.
Use 'git -C <dir> cmd...', so we don't need to change directory, and
thus don't need the subshell either when setting $old_commit.
Furthermore, change check_push_result() to require at least three
parameters (the repo, the oid, and at least one ref), so it will catch
similar issues earlier should they ever arise.

t5516 "75 - deny fetch unreachable SHA1, allowtipsha1inwant=true" is
flaky in the following case:
1. remote upload-pack finds out "not our ref"
2. remote sends a response and closes the pipe
3. fetch-pack still tries to write commands to the remote upload-pack
4. write call in wrapper.c dies with SIGPIPE
The test is flaky because the sending fetch-pack may or may
not have finished writing its output by step (3). If it did,
then we see a closed pipe on the next read() call. If it
didn't, then we get the SIGPIPE from step (4) above. Both
are fine, but the latter fools test_must_fail.
t5504 "9 - push with transfer.fsckobjects" is flaky, too, and returns
SIGPIPE once in a while. I had to remove the final "To dst..." output
check because there is no output if the process dies with SIGPIPE.

With uploadpack.allowReachableSHA1InWant configuration option set on the
server side, "git fetch" can make a request with a "want" line that names
an object that has not been advertised (likely to have been obtained out
of band or from a submodule pointer). Only objects reachable from the
branch tips, i.e. the union of advertised branches and branches hidden by
transfer.hideRefs, will be processed. Note that there is an associated
cost of having to walk back the history to check the reachability.
This feature can be used when obtaining the content of a certain commit,
for which the sha1 is known, without the need of cloning the whole
repository, especially if a shallow fetch is used. Useful cases are e.g.
repositories containing large files in the history, fetching only the
needed data for a submodule checkout, when sharing a sha1 without telling
which exact branch it belongs to and in Gerrit, if you think in terms of
commits instead of change numbers. (The Gerrit case has already been
solved through allowTipSHA1InWant as every Gerrit change has a ref.)

"git fetch" that fetches a commit using the allow-tip-sha1-in-want
extension could have failed to fetch all the requested refs.
* jk/fetch-pack:
fetch-pack: remove dead assignment to ref->new_sha1
fetch_refs_via_pack: free extra copy of refs
filter_ref: make a copy of extra "sought" entries
filter_ref: avoid overwriting ref->old_sha1 with garbage
|
|
If the server supports allow_tip_sha1_in_want, we add any
unmatched raw-sha1 entries in our "sought" list of refs to
the list of refs we will ask the other side for. We do so by
inserting the original "struct ref" directly into our list,
rather than making a copy. This has several problems.
The most minor problem is that one cannot ever free the
resulting list; it contains structs that are copies of the
remote refs (made earlier by fetch_pack) along with sought
refs that are referenced elsewhere.
But more importantly that we set the ref->next pointer to
NULL, chopping off the remainder of any existing list that
the ref was a part of. We get the set of "sought" refs in
an array rather than a linked list, but that array is often
in turn generated from a list. The test modification in
t5516 demonstrates this. Rather than fetching just an exact
sha1, we fetch that sha1 plus another ref:
- we build a linked list of refs to fetch when do_fetch
calls get_ref_map; the exact sha1 is first, followed by
the named ref ("refs/heads/extra" in this case).
- we pass that linked list to transport_fetch_ref, which
squashes it into an array of pointers
- that array goes to fetch_pack, which calls filter_ref.
There we generate the want list from a mix of what the
remote side has advertised, and the "sought" entry for
the exact sha1. We set the sought entry's "next" pointer
to NULL.
- after we return from transport_fetch_refs, we then try
to update the refs by following the linked list. But our
list is now truncated, and we do not update
refs/heads/extra at all.
We can fix this by making a copy of the ref. There's nothing
that fetch_pack does to it that must be reflected in the
original "sought" list (and indeed, if that were the case we
would have a serious bug, because it is only exact-sha1
entries which are treated this way).

When receive.denyCurrentBranch is set to updateInstead, a push that
tries to update the branch that is currently checked out is accepted
only when the index and the working tree exactly matches the
currently checked out commit, in which case the index and the
working tree are updated to match the pushed commit. Otherwise the
push is refused.
This hook can be used to customize this "push-to-deploy" logic. The
hook receives the commit with which the tip of the current branch is
going to be updated, and can decide what kind of local changes are
acceptable and how to update the index and the working tree to match
the updated tip of the current branch.
For example, the hook can simply run `git read-tree -u -m HEAD "$1"`
in order to emulate 'git fetch' that is run in the reverse direction
with `git push`, as the two-tree form of `read-tree -u -m` is
essentially the same as `git checkout` that switches branches while
keeping the local changes in the working tree that do not interfere
with the difference between the branches.

The previous one tests only the case where a path to be updated by
the push-to-deploy has an incompatible change in the target's
working tree that has already been added to the index, but the
feature itself wants to require the working tree to be a lot cleaner
than what is tested. Add a handful more tests to protect the
feature from future changes that mistakenly (from the viewpoint of
the inventor of the feature) loosens the cleanliness requirement,
namely:
- A change only to the working tree but not to the index is still a
change to be protected;
- An untracked file in the working tree that would be overwritten
by a push-to-deploy needs to be protected;
- A change that happens to make a file identical to what is being
pushed is still a change to be protected (i.e. the feature's
cleanliness requirement is more strict than that of checkout).
Also, test that a stat-only change to the working tree is not a
reason to reject a push-to-deploy.

When synchronizing between working directories, it can be handy to update
the current branch via 'push' rather than 'pull', e.g. when pushing a fix
from inside a VM, or when pushing a fix made on a user's machine (where
the developer is not at liberty to install an ssh daemon let alone know
the user's password).
The common workaround – pushing into a temporary branch and then merging
on the other machine – is no longer necessary with this patch.
The new option is:
'updateInstead':
Update the working tree accordingly, but refuse to do so if there
are any uncommitted changes.

Corner-case bugfixes for "git fetch" around reflog handling.
* jk/fetch-reflog-df-conflict:
ignore stale directories when checking reflog existence
fetch: load all default config at startup
|
|
When we start the git-fetch program, we call git_config to
load all config, but our callback only processes the
fetch.prune option; we do not chain to git_default_config at
all.
This means that we may not load some core configuration
which will have an effect. For instance, we do not load
core.logAllRefUpdates, which impacts whether or not we
create reflogs in a bare repository.
Note that I said "may" above. It gets even more exciting. If
we have to transfer actual objects as part of the fetch,
then we call fetch_pack as part of the same process. That
function loads its own config, which does chain to
git_default_config, impacting global variables which are
used by the rest of fetch. But if the fetch is a pure ref
update (e.g., a new ref which is a copy of an old one), we
skip fetch_pack entirely. So we get inconsistent results
depending on whether or not we have actual objects to
transfer or not!
Let's just load the core config at the start of fetch, so we
know we have it (we may also load it again as part of
fetch_pack, but that's OK; it's designed to be idempotent).
Our tests check both cases (with and without a pack). We
also check similar behavior for push for good measure, but
it already works as expected.

It's not unreasonable to have a tag that points to a blob
that is not part of the normal history. We do this in
git.git to distribute gpg keys. However, we never explicitly
checked in our test suite that this actually works (i.e.,
that pack-objects actually sends the blob because of the tag
mentioning it).
It does in fact work fine, but a recent patch under
discussion broke this, and the test suite didn't notice.
Let's make the test suite more complete.

"git push" did not pay attention to branch.*.pushremote if it is
defined earlier than remote.pushdefault; the order of these two
variables in the configuration file should not matter, but it did by
mistake.
* jk/remote-pushremote-config-reading:
remote: handle pushremote config in any order
|
|
The remote we push can be defined either by
remote.pushdefault or by branch.*.pushremote for the current
branch. The order in which they appear in the config file
should not matter to precedence (which should be to prefer
the branch-specific config).
The current code parses the config linearly and uses a
single string to store both values, overwriting any
previous value. Thus, config like:
[branch "master"]
pushremote = foo
[remote]
pushdefault = bar
erroneously ends up pushing to "bar" from the master branch.
We can fix this by storing both values and resolving the
correct value after all config is read.

When the user is using the 'upstream' mode, these commands:
$ git push
$ git push origin
would find the 'upstream' branch for the current branch, and then
push the current branch to update it. However, pushing a single
branch explicitly, i.e.
$ git push origin $(git symbolic-ref --short HEAD)
would not go through the same ref mapping process, and ends up
updating the branch at 'origin' of the same name, which may not
necessarily be the upstream of the branch being pushed.
In the spirit similar to the previous one, map a colon-less refspec
using the upstream mapping logic.

Since f2690487 (fetch: opportunistically update tracking refs,
2013-05-11), we stopped taking a non-storing refspec given on the
command line of "git fetch" literally, and instead started mapping
it via remote.$name.fetch refspecs. This allows
$ git fetch origin master
from the 'origin' repository, which is configured with
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
to update refs/remotes/origin/master with the result, as if the
command line were
$ git fetch origin +master:refs/remotes/origin/master
to reduce surprises and improve usability. Before that change, a
refspec on the command line without a colon was only to fetch the
history and leave the result in FETCH_HEAD, without updating the
remote-tracking branches.
When you are simulating a fetch from you by your mothership with a
push by you into your mothership, instead of having:
[remote "satellite"]
fetch = +refs/heads/*:refs/remotes/satellite/*
on the mothership repository and running:
mothership$ git fetch satellite
you would have:
[remote "mothership"]
push = +refs/heads/*:refs/remotes/satellite/*
on your satellite machine, and run:
satellite$ git push mothership
Because we so far did not make the corresponding change to the push
side, this command:
satellite$ git push mothership master
does _not_ allow you on the satellite to only push 'master' out but
still to the usual destination (i.e. refs/remotes/satellite/master).
Implement the logic to map an unqualified refspec given on the
command line via the remote.$name.push refspec. This will bring a
bit more symmetry between "fetch" and "push".

- From the beginning of push.c in 755225d, 2006-04-29, "thin" option
was enabled by default but could be turned off with --no-thin.
- Then Shawn changed the default to 0 in favor of saving server
resources in a4503a1, 2007-09-09. --no-thin worked great.
- One day later, in 9b28851 Daniel extracted some code from push.c to
create transport.c. He (probably accidentally) flipped the default
value from 0 to 1 in transport_get().
From then on --no-thin is effectively no-op because git-push still
expects the default value to be false and only calls
transport_set_option() when "thin" variable in push.c is true (which
is unnecessary). Correct the code to respect --no-thin by calling
transport_set_option() in both cases.
receive-pack learns about --reject-thin-pack-for-testing option,
which only is for testing purposes, hence no document update.
