Junio C Hamano 4d7a5ceacc t5516: more tests for receive.denyCurrentBranch=updateInstead
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.

Johannes Schindelin 1404bcbb6b receive-pack: add another option for receive.denyCurrentBranch
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.

Junio C Hamano a1671dd82b Merge branch 'jk/fetch-reflog-df-conflict'
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
2014-11-06 10:52:32 -08:00
Jeff King 72549dfd5d 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.

Jeff King 458a7e508c t5516: test pushing a tag of an otherwise unreferenced blob
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.

Junio C Hamano d52571d5c1 Merge branch 'jk/remote-pushremote-config-reading'
"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.

2014-03-14 14:26:05 -07:00
Jeff King 98b406f3ad 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.

Junio C Hamano fc9261ca61 push: also use "upstream" mapping when pushing a single ref
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.

Junio C Hamano ca02465b41 push: use remote.$name.push as a refmap
Since f2690487 (fetch: opportunistically update tracking refs,
2013-05-11), we stopped taking a non-storing refspec given on the
command line of "git fetch" literally, and instead started mapping
it via remote.$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".

Nguyễn Thái Ngọc Duy f7c815c3ee push: respect --no-thin
- 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.

Many of the tests in t5516 look like:

  mk_empty &&
  git push testrepo ... &&
  check_push_result $commit heads/master

It's reasonably easy to see what is being tested, with the
exception that "testrepo" is a magic global name (it is
implicitly used in the helpers, but we have to name it
explicitly when calling git directly). Let's make it
explicit when call the helpers, too. This is slightly more
typing, but makes the test snippets read more naturally.

It also makes it easy for future tests to use an alternate
or multiple repositories, without a proliferation of helper
functions.

Junio C Hamano daebaa7813 upload/receive-pack: allow hiding ref hierarchies
A repository may have refs that are only used for its internal
bookkeeping purposes that should not be exposed to the others that
come over the network.

Teach upload-pack to omit some refs from its initial advertisement
by paying attention to the uploadpack.hiderefs multi-valued
configuration variable.  Do the same to receive-pack via the
receive.hiderefs variable.  As a convenient short-hand, allow using
transfer.hiderefs to set the value to both of these variables.

Any ref that is under the hierarchies listed on the value of these
variable is excluded from responses to requests made by "ls-remote",
"fetch", etc. (for upload-pack) and "push" (for receive-pack).

Because these hidden refs do not count as OUR_REF, an attempt to
fetch objects at the tip of them will be rejected, and because these
refs do not get advertised, "git push :" will not see local branches
that have the same name as them as "matching" ones to be sent.

An attempt to update/delete these hidden refs with an explicit
refspec, e.g. "git push origin :refs/hidden/22", is rejected.  This
is not a new restriction.  To the pusher, it would appear that there
is no such ref, so its push request will conclude with "Now that I
sent you all the data, it is time for you to update the refs.  I saw
that the ref did not exist when I started pushing, and I want the
result to point at this commit".  The receiving end will apply the
compare-and-swap rule to this request and rejects the push with
"Well, your update request conflicts with somebody else; I see there
is such a ref.", which is the right thing to do. Otherwise a push to
a hidden ref will always be "the last one wins", which is not a good
default.

Junio C Hamano 256b9d70a4 push: fix "refs/tags/ hierarchy cannot be updated without --force"
When pushing to update a branch with a commit that is not a
descendant of the commit at the tip, a wrong message "already
exists" was given, instead of the correct "non-fast-forward", if we
do not have the object sitting in the destination repository at the
tip of the ref we are updating.

The primary cause of the bug is that the check in a new helper
function is_forwardable() assumed both old and new objects are
available and can be checked, which is not always the case.

The way the caller uses the result of this function is also wrong.
If the helper says "we do not want to let this push go through", the
caller unconditionally translates it into "we blocked it because the
destination already exists", which is not true at all in this case.

Fix this by doing these three things:

 * Remove unnecessary not_forwardable from "struct ref"; it is only
   used inside set_ref_status_for_push();

 * Make "refs/tags/" the only hierarchy that cannot be replaced
   without --force;

 * Remove the misguided attempt to force that everything that
   updates an existing ref has to be a commit outside "refs/tags/"
   hierarchy.

The policy last one tried to implement may later be resurrected and
extended to ensure fast-forwardness (defined as "not losing
objects", extending from the traditional "not losing commits from
the resulting history") when objects that are not commit are
involved (e.g. an annotated tag in hierarchies outside refs/tags),
but such a logic belongs to "is this a fast-forward?" check that is
done by ref_newer(); is_forwardable(), which is now removed, was not
the right place to do so.

Pang Yan Han 160b81ed81 receive-pack: don't pass non-existent refs to post-{receive,update} hooks
When a push specifies deletion of non-existent refs, the post post-receive and
post-update hooks receive them as input/arguments.

For instance, for the following push, where refs/heads/nonexistent is a ref
which does not exist on the remote side:

	git push origin :refs/heads/nonexistent

the post-receive hook receives from standard input:

	<null-sha1> SP <null-sha1> SP refs/heads/nonexistent

and the post-update hook receives as arguments:

	refs/heads/nonexistent

which does not make sense since it is a no-op.

Teach receive-pack not to pass non-existent refs to the post-receive and
post-update hooks. If the push only attempts to delete non-existent refs,
these hooks are not even called.

The update and pre-receive hooks are still notified about attempted
deletion of non-existent refs to give them a chance to inspect the
situation and act on it.

bert Dvornik fc012c2810 start_command: close cmd->err descriptor when fork/spawn fails
Fix the problem where the cmd->err passed into start_command wasn't
being properly closed when certain types of errors occurr.  (Compare
the affected code with the clean shutdown code later in the function.)

On Windows, this problem would be triggered if mingw_spawnvpe()
failed, which would happen if the command to be executed was malformed
(e.g. a text file that didn't start with a #! line).  If cmd->err was
a pipe, the failure to close it could result in a hang while the other
side was waiting (forever) for either input or pipe close, e.g. while
trying to shove the output into the side band.  On msysGit, this
problem was causing a hang in t5516-fetch-push.

observed on Linux.]

Jay Soffian da3efdb17b receive-pack: detect aliased updates which can occur with symrefs
When pushing to a remote repo the sending side filters out aliased
updates (e.g., foo:baz bar:baz). However, it is not possible for the
sender to know if two refs are aliased on the receiving side via
symrefs. Here is one such scenario:

  $ git init origin
  $ (cd origin && touch file && git add file && git commit -a -m intial)
  $ git clone --bare origin origin.git
  $ rm -rf origin

  $ git clone origin.git client

  $ git clone --mirror client backup.git &&
  $ (cd backup.git && git remote set-head origin --auto)

  $ (cd client &&
	git remote add --mirror backup ../backup.git &&
	echo change1 > file && git commit -a -m change1 &&
	git push origin &&
	git push backup
	)

The push to backup fails with:

  Counting objects: 5, done.
  Writing objects: 100% (3/3), 244 bytes, done.
  Total 3 (delta 0), reused 0 (delta 0)
  Unpacking objects: 100% (3/3), done.
  error: Ref refs/remotes/origin/master is at ef3... but expected 262...
  remote: error: failed to lock refs/remotes/origin/master
  To ../backup.git
     262cd57..ef307ff  master -> master
     262cd57..ef307ff  origin/HEAD -> origin/HEAD
   ! [remote rejected] origin/master -> origin/master (failed to lock)
  error: failed to push some refs to '../backup.git'

The reason is that refs/remotes/origin/HEAD is a symref to
refs/remotes/origin/master, but it is not possible for the sending side
to unambiguously know this.

This commit fixes the issue by having receive-pack ignore any update to
a symref whose target is being identically updated. If a symref and its
target are being updated inconsistently, then the update for both fails
with an error message ("refusing inconsistent update...") to help
diagnose the situation.

Jeff King 986e82396a receive-pack: detect push to current branch of non-bare repo
Pushing into the currently checked out branch of a non-bare
repository can be dangerous; the HEAD then loses sync with
the index and working tree, and it looks in the receiving
repo as if the pushed changes have been reverted in the
index (since they were never there in the first place).

This patch adds a safety valve that checks for this
condition and either generates a warning or denies the
update. We trigger the check only on a non-bare repository,
since a bare repo does not have a working tree (and in fact,
pushing to the HEAD branch is a common workflow for
publishing repositories).

The behavior is configurable via receive.denyCurrentBranch,
defaulting to "warn" so as not to break existing setups
(though it may, after a deprecation period, switch to
"refuse" by default). For users who know what they are doing
and want to silence the warning (e.g., because they have a
post-receive hook that reconciles the HEAD and working
tree), they can turn off the warning by setting it to false
or "ignore".

Jeff King b2dc968e60 t5516: refactor oddball tests
t5516 sets up some utility functions for starting each test
with a clean slate. However, there were a few tests added
that do not use these functions, but instead make their own
repositories.

Let's bring these in line with the rest of the tests. Not
only do we reduce the number of lines, but these tests will
benefit from any further enhancements to the utility
scripts.

The conversion is pretty straightforward. Most of the tests
created a parent/child clone relationship, for which we now
use 'testrepo' as the parent.  One test looked in testrepo,
but relied on previous tests to have set it up; it now sets
up testrepo explicitly, which makes it a bit more robust to
changes in the script, as well.

Bryan Donlan f69e836fab Fix tests breaking when checkout path contains shell metacharacters
This fixes the remainder of the issues where the test script itself is at
fault for failing when the git checkout path contains whitespace or other
shell metacharacters.

The majority of git svn tests used the idiom

  test_expect_success "title" "test script using $svnrepo"

These were changed to have the test script in single-quotes:

  test_expect_success "title" 'test script using "$svnrepo"'

which unfortunately makes the patch appear larger than it really is.

One consequence of this change is that in the verbose test output the
value of $svnrepo (and in some cases other variables, too) is no
longer expanded, i.e. previously we saw

  * expecting success:
	test script using /path/to/git/t/trash/svnrepo

Jeff King f8aae12034 push: allow unqualified dest refspecs to DWIM
Previously, a push like:

  git push remote src:dst

would go through the following steps:

  1. check for an unambiguous 'dst' on the remote; if it
     exists, then push to that ref
  2. otherwise, check if 'dst' begins with 'refs/'; if it
     does, create a new ref
  3. otherwise, complain because we don't know where in the
     refs hierarchy to put 'dst'

However, in some cases, we can guess about the ref type of
'dst' based on the ref type of 'src'. Specifically, before
complaining we now check:

  2.5. if 'src' resolves to a ref starting with refs/heads
       or refs/tags, then prepend that to 'dst'

So now this creates a new branch on the remote, whereas it
previously failed with an error message:

  git push master:newbranch

Note that, by design, we limit this DWIM behavior only to
source refs which resolve exactly (including symrefs which
resolve to existing refs). We still complain on a partial
destination refspec if the source is a raw sha1, or a ref
expression such as 'master~10'.

Johannes Schindelin 28391a80a9 receive-pack: allow deletion of corrupt refs
Occasionally, in some setups (*cough* forks on repo.or.cz *cough*) some
refs go stale, e.g. when the forkee rebased and lost some objects needed
by the fork.  The quick & dirty way to deal with those refs is to delete
them and push them again.

However, git-push first would first fetch the current commit name for the
ref, would receive a null sha1 since the ref does not point to a valid
object, then tell receive-pack that it should delete the ref with this
commit name.  delete_ref() would be subsequently be called, and check that
resolve_ref() (which does _not_ check for validity of the object) returns
the same commit name.  Which would fail.

The proper fix is to avoid corrupting repositories, but in the meantime
this is a good fix in any case.

Incidentally, some instances of "cd .." in the test cases were fixed, so
that subsequent test cases run in t/trash/ irrespective of the outcome of
the previous test cases.

This commit changes the rules for resolving refspecs to match the
rules for resolving refs in rev-parse. git-rev-parse uses clear rules
to resolve a short ref to its full name, which are well documented.
The rules for resolving refspecs documented in git-send-pack were
less strict and harder to understand. This commit replaces them by
the rules of git-rev-parse.

The unified rules are easier to understand and better resolve ambiguous
cases. You can now push from a repository containing several branches
ending on the same short name.

Note, this may break existing setups. For example, "master" will no longer
resolve to "origin/master" even when there is no other "master" elsewhere.

Earlier, when the local repository has a branch "frotz" and the
remote repository has a tag "frotz" (but not branch "frotz"),
"git-push frotz" mistakenly updated the tag at the remote side.
This was because the partial refname matching code was applied
independently on both source and destination side.

With this fix, when a colon-less refspec is given to git-push,
we first match it with the refs in the source repository, and
update the matching ref in the destination repository.

Junio C Hamano 6125796f7d remote.c: fix "git push" weak match disambiguation
When "git push A:B" is given, and A (or B) is not a full refname
that begins with refs/, we require an unambiguous match with an
existing ref.  For this purpose, a match with a local branch or
a tag (i.e. refs/heads/A and refs/tags/A) is called a "strong
match", and any other match is called a "weak match".  A partial
refname is unambiguous when there is only one strong match with
any number of weak matches, or when there is only one weak match
and no other match.

However, as reported by Sparse with Ramsay Jones recently,
count_refspec_match() function had a bug where a variable in an
inner block masked a different variable of the same name, which
caused the weak matches to be ignored.

This fixes it, and adds tests for the fix.
