2020-11-30refspec: make @ a synonym of HEADLibravatar Felipe Contreras1-51/+56
Since commit 9ba89f484e git learned how to push to a remote branch using the source @, for example: git push origin @:master However, if the right-hand side is missing, the push fails: git push origin @ It is obvious what is the desired behavior, and allowing the push makes things more consistent. Additionally, @:master now has the same semantics as HEAD:master. Signed-off-by: Felipe Contreras <felipe.contreras@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-04-17send-pack: fix inconsistent porcelain outputLibravatar Jiang Xin1-0/+1
The porcelain output of a failed `git-push` command is inconsistent for different protocols. For example, the following `git-push` command may fail due to the failure of the `pre-receive` hook. git push --porcelain origin HEAD:refs/heads/master For SSH protocol, the porcelain output does not end with a "Done" message: To <URL/of/upstream.git> ! HEAD:refs/heads/master [remote rejected] (pre-receive hook declined) While for HTTP protocol, the porcelain output does end with a "Done" message: To <URL/of/upstream.git> ! HEAD:refs/heads/master [remote rejected] (pre-receive hook declined) Done The following code at the end of function `send_pack()` indicates that `send_pack()` should not return an error if some references are rejected in porcelain mode. int send_pack(...) ... ... if (args->porcelain) return 0; for (ref = remote_refs; ref; ref = ref->next) { switch (ref->status) { case REF_STATUS_NONE: case REF_STATUS_UPTODATE: case REF_STATUS_OK: break; default: return -1; } } return 0; } So if atomic push failed, must check the porcelain mode before return an error. And `receive_status()` should not return an error for a failed updated reference, because `send_pack()` will check them instead.

2020-03-05Merge branch 'hv/receive-denycurrent-everywhere'Libravatar Junio C Hamano1-0/+11
"git push" should stop from updating a branch that is checked out when receive.denyCurrentBranch configuration is set, but it failed to pay attention to checkouts in secondary worktrees. This has been corrected. * hv/receive-denycurrent-everywhere: t2402: test worktree path when called in .git directory receive.denyCurrentBranch: respect all worktrees t5509: use a bare repository for test push target get_main_worktree(): allow it to be called in the Git directory
2020-02-24receive.denyCurrentBranch: respect all worktreesLibravatar Hariom Verma1-0/+11
The receive.denyCurrentBranch config option controls what happens if you push to a branch that is checked out into a non-bare repository. By default, it rejects it. It can be disabled via `ignore` or `warn`. Another yet trickier option is `updateInstead`. However, this setting was forgotten when the git worktree command was introduced: only the main worktree's current branch is respected. With this change, all worktrees are respected. That change also leads to revealing another bug, i.e. `receive.denyCurrentBranch = true` was ignored when pushing into a non-bare repository's unborn current branch using ref namespaces. As `is_ref_checked_out()` returns 0 which means `receive-pack` does not get into conditional statement to switch `deny_current_branch` accordingly (ignore, warn, refuse, unconfigured, updateInstead). receive.denyCurrentBranch uses the function `refs_resolve_ref_unsafe()` (called via `resolve_refdup()`) to resolve the symbolic ref HEAD, but that function fails when HEAD does not point at a valid commit. As we replace the call to `refs_resolve_ref_unsafe()` with `find_shared_symref()`, which has no problem finding the worktree for a given branch even if it is unborn yet, this bug is fixed at the same time: receive.denyCurrentBranch now also handles worktrees with unborn branches as intended even while using ref namespaces.

2020-01-15test: request GIT_TEST_PROTOCOL_VERSION=0 when appropriateLibravatar Jonathan Nieder1-6/+6
Since 8cbeba0632 (tests: define GIT_TEST_PROTOCOL_VERSION, 2019-02-25), it has been possible to run tests with a newer protocol version by setting the GIT_TEST_PROTOCOL_VERSION envvar to a version number. Tests that assume protocol v0 handle this by explicitly setting GIT_TEST_PROTOCOL_VERSION= or similar constructs like 'test -z "$GIT_TEST_PROTOCOL_VERSION" || return 0' to declare that they only handle the default (v0) protocol. The emphasis there is a bit off: it would be clearer to specify GIT_TEST_PROTOCOL_VERSION=0 to inform the reader that these tests are specifically testing and relying on details of protocol v0. Do so. This way, a reader does not need to know what the default protocol version is, and the tests can continue to work when the default protocol version used by Git advances past v0.

2019-04-15fetch: do not consider peeled tags as advertised tipsLibravatar Jeff King1-0/+11
Our filter_refs() function accidentally considers the target of a peeled tag to be advertised by the server, even though upload-pack on the server side does not consider it so. This can result in the client making a bogus fetch to the server, which will end with the server complaining "not our ref". Whereas the correct behavior is for the client to notice that the server will not allow the request and error out immediately. So as bugs go, this is not very serious (the outcome is the same either way -- the fetch fails). But it's worth making the logic here correct and consistent with other related cases (e.g., fetching an oid that the server did not mention at all). The crux of the issue comes from fdb69d33c4 (fetch-pack: always allow fetching of literal SHA1s, 2017-05-15). After that, the strategy of filter_refs() is basically: - for each advertised ref, try to match it with a "sought" ref provided by the user. Skip any malformed refs (which includes peeled values like "refs/tags/foo^{}"), and place any unmatched items onto the unmatched list. - if there are unmatched sought refs, then put all of the advertised tips into an oidset, including the unmatched ones. - for each sought ref, see if it's in the oidset, in which case it's legal for us to ask the server for it The problem is in the second step. Our list of unmatched refs includes the peeled refs, even though upload-pack does not allow them to be directly fetched. So the simplest fix would be to exclude them during that step. However, we can observe that the unmatched list isn't used for anything else, and is freed at the end. We can just free those malformed refs immediately. That saves us having to check each ref a second time to see if it's malformed. Note that this code only kicks in when "strict" is in effect. I.e., if we are using the v0 protocol and uploadpack.allowReachableSHA1InWant is not in effect. With v2, all oids are allowed, and we do not bother creating or consulting the oidset at all. To future-proof our test against the upcoming GIT_TEST_PROTOCOL_VERSION flag, we'll manually mark it as a v0-only test.

2019-04-15pkt-line: prepare buffer before handling ERR packetsLibravatar Jeff King1-1/+1
Since 2d103c31c2 (pack-protocol.txt: accept error packets in any context, 2018-12-29), the pktline code will detect an ERR packet and die automatically, saving the caller from dealing with it. But we do so too early in the function, before we have terminated the buffer with a NUL. As a result, passing the ERR message to die() may result in us printing random cruft from a previous packet. This doesn't trigger memory tools like ASan because we reuse the same buffer over and over (so the contents are valid and initialized; they're just stale). We can see demonstrate this by tightening the regex we use to match the error message in t5516; without this patch, git-fetch will accidentally print the capabilities from the (much longer) initial packet we received. By moving the ERR code later in the function we get a few other benefits, too: - we'll now chomp any newline sent by the other side (which is what we want, since die() will add its own newline) - we'll now mention the ERR packet with GIT_TRACE_PACKET Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-04-15upload-pack: send ERR packet for non-tip objectsLibravatar Jeff King1-1/+2
Commit bdb31eada7 (upload-pack: report "not our ref" to client, 2017-02-23) catches the case where a client asks for an object we don't have, and issues a message that the client can show to the user (in addition to dying and writing to stderr). There's a similar case (with the same message) when the client asks for an object which we _do_ have, but which isn't a ref tip (or isn't reachable, when uploadpack.allowReachableSHA1InWant is true). Let's give that one the same treatment, for the same reason (namely that it's more informative to the client than just hanging up, since they won't see our stderr over some protocols). There are two tests here. We cover it most directly in t5530 by invoking upload-pack, which matches the existing "not our ref" test. But a more end-to-end check is that "git fetch" actually shows the message to the client. We're already checking in t5516 that this case fails, so we can just check stderr there, too. Note that even after we started ignoring SIGPIPE in 8bf4becf0c, this could in theory still be racy as described in that commit (because we die() on write failures before pumping the connection for any ERR packets). In practice this should be OK for this case. The server will not actually check reachability until it has received our whole group of "want" lines. And since we have no objects in the repository, we won't send any "have" lines, meaning we're always waiting to read the server response. Note also that this case cannot happen in the v2 protocol, since it allows any available object to be requested. However, we don't have to take any steps to protect against the upcoming GIT_TEST_PROTOCOL_VERSION in our tests: - the tests in t5516 would already need to be skipped under v2, and that is covered by ab0c5f5096 (tests: always test fetch of unreachable with v0, 2019-02-25) - the tests in t5530 invoke upload-pack directly, which will continue to default to v0. Eventually we may have a test setting which uses v2 even for bare upload-pack calls, but we can't override it here until we know what the setting looks like.

We annotated our test_must_fail calls in 8bf4becf0c (add "ok=sigpipe" to test_must_fail and use it to fix flaky tests, 2015-11-27) because the abrupt hangup of the server meant that we'd sometimes fail on read() and sometimes get SIGPIPE on write(). But since 143588949c (fetch: ignore SIGPIPE during network operation, 2019-03-03), we make sure that we end up with a real die(), and our tests no longer need to work around the race.

2018-11-20tests: send "bug in the test script" errors to the script's stderrLibravatar SZEDER Gábor1-1/+1
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 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.

2018-08-31fetch: stop clobbering existing tags without --forceLibravatar Ævar Arnfjörð Bjarmason1-2/+3
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.

Changes code initially added in dbfeddb12e ("push: require force for refs under refs/tags/", 2012-11-29).

2018-06-01fetch: do not pass ref-prefixes for fetch by exact SHA1Libravatar Jonathan Nieder1-0/+19
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> ref-prefix refs/tags/12039e008f9a4e3394f3f94f8ea897785cb09448 packet: fetch> ref-prefix refs/heads/12039e008f9a4e3394f3f94f8ea897785cb09448 packet: fetch> ref-prefix refs/remotes/12039e008f9a4e3394f3f94f8ea897785cb09448 packet: fetch> ref-prefix refs/remotes/12039e008f9a4e3394f3f94f8ea897785cb09448/HEAD 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.

Many tests hardcode the raw object names, which would change once we migrate away from SHA-1. While some of them must test against exact object names, most of them do not have to use hardcoded constants in the test. The latter kind of tests have been updated to test the moral equivalent of the original without hardcoding the actual object names. * bc/hash-independent-tests: (28 commits) t5300: abstract away SHA-1-specific constants t4208: abstract away SHA-1-specific constants t4045: abstract away SHA-1-specific constants t4042: abstract away SHA-1-specific constants t4205: sort log output in a hash-independent way t/lib-diff-alternative: abstract away SHA-1-specific constants t4030: abstract away SHA-1-specific constants t4029: abstract away SHA-1-specific constants t4029: fix test indentation t4022: abstract away SHA-1-specific constants t4020: abstract away SHA-1-specific constants t4014: abstract away SHA-1-specific constants t4008: abstract away SHA-1-specific constants t4007: abstract away SHA-1-specific constants t3905: abstract away SHA-1-specific constants t3702: abstract away SHA-1-specific constants t3103: abstract away SHA-1-specific constants t2203: abstract away SHA-1-specific constants t: skip pack tests if not using SHA-1 t4044: skip test if not using SHA-1 ...

2018-05-11t5516-fetch-push: fix 'push with dry-run' testLibravatar SZEDER Gábor1-4/+4
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.

Enhance filter_refs (which decides whether a request for an unadvertised object should be sent to the server) to record a new match status on the "struct ref" when a request is not allowed, and have report_unmatched_refs check for this status and print a special error message, "Server does not allow request for unadvertised object".

2017-03-02fetch_refs_via_pack: call report_unmatched_refsLibravatar Matt McCutchen1-1/+2
"git fetch" currently doesn't bother to check that it got all refs it sought, because the common case of requesting a nonexistent ref triggers a die() in get_fetch_map. However, there's at least one case that slipped through: "git fetch REMOTE SHA1" if the server doesn't allow requests for unadvertised objects. Make fetch_refs_via_pack (which is on the "git fetch" code path) call report_unmatched_refs so that we at least get an error message in that case.

2015-12-28t/t5516-fetch-push.sh: use the $( ... ) construct for command substitutionLibravatar Elia Pinto1-2/+2
The Git CodingGuidelines prefer the $(...) construct for command substitution instead of using the backquotes `...`. The backquoted form is the traditional method for command substitution, and is supported by POSIX. However, all but the simplest uses become complicated quickly. In particular, embedded command substitutions and/or the use of double quotes require careful escaping with the backslash character. The patch was generated by: for _f in $(find . -name "*.sh") do perl -i -pe 'BEGIN{undef $/;} s/`(.+?)`/\$(\1)/smg' "${_f}" done and then carefully proof-read.

2015-11-28add "ok=sigpipe" to test_must_fail and use it to fix flaky testsLibravatar Lars Schneider1-3/+3
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. Accept such a death-with-sigpipe also as OK when we are expecting a failure.

2015-05-22upload-pack: optionally allow fetching reachable sha1Libravatar Fredrik Medley1-0/+55
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.)
