2018-08-31fetch: stop clobbering existing tags without --forceLibravatar Ævar Arnfjörð Bjarmason2-4/+5
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. 1. https://public-inbox.org/git/20111123221658.GA22313@sigill.intra.peff.net/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-08-31fetch tests: add a test for clobbering tag behaviorLibravatar Ævar Arnfjörð Bjarmason1-0/+24
The test suite only incidentally (and unintentionally) tested for the current behavior of eager tag clobbering on "fetch".

Change the test that asserts that lightweight tags can only be clobbered by a force-push to check do the same tests for annotated tags. There used to be less exhaustive tests for this with the code added in 40eff17999 ("push: require force for annotated tags", 2012-11-29), but Junio removed them in 256b9d70a4 ("push: fix "refs/tags/ hierarchy cannot be updated without --force"", 2013-01-16) while fixing some of the behavior around tag pushing. That change left us without any coverage asserting that pushing and clobbering annotated tags worked as intended.

2018-07-31push tests: add more testing for forced tag pushingLibravatar Ævar Arnfjörð Bjarmason1-2/+20
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.

Fix a logic error that's been here since this test was added in dbfeddb12e ("push: require force for refs under refs/tags/", 2012-11-29). The intent of this test is to force-create a new tag pointing to HEAD~, and then assert that pushing it doesn't work without --force. Instead, the code was not creating a new tag at all, and then failing to push the previous tag for the unrelated reason of providing a refspec that doesn't make any sense.

2018-07-16t/check-non-portable-shell: detect "FOO=bar shell_func"Libravatar Eric Sunshine1-0/+19
One-shot environment variable assignments, such as 'FOO' in "FOO=bar cmd", exist only during the invocation of 'cmd'. However, if 'cmd' happens to be a shell function, then 'FOO' is assigned in the executing shell itself, and that assignment remains until the process exits (unless explicitly unset). Since this side-effect of "FOO=bar shell_func" is unlikely to be intentional, detect and report such usage. To distinguish shell functions from other commands, perform a pre-scan of shell scripts named as input, gleaning a list of function names by recognizing lines of the form (loosely matching whitespace): shell_func () { and later report suspect lines of the form (loosely matching quoted values): FOO=bar [BAR=foo ...] shell_func Also take care to stitch together incomplete lines (those ending with "\") since suspect invocations may be split over multiple lines: FOO=bar BAR=foo \ shell_func Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Unlike "FOO=bar cmd" one-shot environment variable assignments which exist only for the invocation of 'cmd', those assigned by "FOO=bar shell_func" exist within the running shell and continue to do so until the process exits (or are explicitly unset). It is unlikely that this behavior was intended by the test author. In these particular tests, the "FOO=bar shell_func" invocations are already in subshells, so the assignments don't last too long, don't appear to harm subsequent commands in the same subshells, and don't affect other tests in the same scripts, however, the usage is nevertheless misleading and poor practice, so fix the tests to assign and export the environment variables in the usual fashion.

If the user gives us a set that prepare_revision_walk() takes to be empty, like: git cherry-pick base..base then we report an error. It's nonsense, and there's nothing to pick. But if they use revision options that later cull the list, like: git cherry-pick --author=nobody base~2..base then we quietly create an empty todo list and return success. Arguably either behavior is acceptable, but we should definitely be consistent about it. Reporting an error seems to match the original intent, which dates all the way back to 7e2bfd3f99 (revert: allow cherry-picking more than one commit, 2010-06-02).

A filter line in a request to upload-pack filters out objects regardless of whether they are directly referenced by a "want" line or not. This means that cloning with "--filter=blob:none" (or another filter that excludes blobs) from a repository with at least one ref pointing to a blob (for example, the Git repository itself) results in output like the following: error: missing object referenced by 'refs/tags/junio-gpg-pub' and if that particular blob is not referenced by a fetched tree, the resulting clone fails fsck because there is no object from the remote to vouch that the missing object is a promisor object. Update both the protocol and the upload-pack implementation to include all explicitly specified "want" objects in the packfile regardless of the filter specification.

2018-07-09send-email: automatically determine transfer-encodingLibravatar brian m. carlson1-0/+21
git send-email, when invoked without a --transfer-encoding option, sends 8bit data without a MIME version or a transfer encoding. This has several downsides. First, unless the transfer encoding is specified, it defaults to 7bit, meaning that non-ASCII data isn't allowed. Second, if lines longer than 998 bytes are used, we will send an message that is invalid according to RFC 5322. The --validate option, which is the default, catches this issue, but it isn't clear to many people how to resolve this. To solve these issues, default the transfer encoding to "auto", so that we explicitly specify 8bit encoding when lines don't exceed 998 bytes and quoted-printable otherwise. This means that we now always emit Content-Transfer-Encoding and MIME-Version headers, so remove the conditionals from this portion of the code. It is unlikely that the unconditional inclusion of these two headers will affect the deliverability of messages in anything but a positive way, since MIME is already widespread and well understood by most email programs.

With --validate (which is the default), we warn about lines exceeding 998 characters due to the limits specified in RFC 5322. However, if we're using a suitable transfer encoding (quoted-printable or base64), we're guaranteed not to have lines exceeding 76 characters, so there's no need to fail in this case. The auto transfer encoding handles this specific case, so accept it as well. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

For most patches, using a transfer encoding of 8bit provides good compatibility with most servers and makes it as easy as possible to view patches. However, there are some patches for which 8bit is not a valid encoding: RFC 5322 specifies that a message must not have lines exceeding 998 octets. Add a transfer encoding value, auto, which indicates that a patch should use 8bit where allowed and quoted-printable otherwise. Choose quoted-printable instead of base64, since base64-encoded plain text is treated as suspicious by some spam filters.

A later patch changes the built-in PHP pattern. These test cases demonstrate aspects of the pattern that we do not want to change. Signed-off-by: Kana Natsuno <dev@whileimautomaton.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-07-06t5500: prettify non-commit tag testsLibravatar Jeff King1-6/+13
We don't need to use backslash continuation, as the "&&" already provides continuation (and happily soaks up empty lines between commands). We can also expand the multi-line printf into a here-document, which lets us use line breaks more naturally (and avoids another continuation that required us to break the natural indentation).

2018-07-03fetch-pack: write shallow, then check connectivityLibravatar Jonathan Tan1-0/+43
When fetching, connectivity is checked after the shallow file is updated. There are 2 issues with this: (1) the connectivity check is only performed up to ancestors of existing refs (which is not thorough enough if we were deepening an existing ref in the first place), and (2) there is no rollback of the shallow file if the connectivity check fails. To solve (1), update the connectivity check to check the ancestry chain completely in the case of a deepening fetch by refraining from passing "--not --all" when invoking rev-list in connected.c. To solve (2), have fetch_pack() perform its own connectivity check before updating the shallow file. To support existing use cases in which "git fetch-pack" is used to download objects without much regard as to the connectivity of the resulting objects with respect to the existing repository, the connectivity check is only done if necessary (that is, the fetch is not a clone, and the fetch involves shallow/deepen functionality). "git fetch" still performs its own connectivity check, preserving correctness but sometimes performing redundant work. This redundancy is mitigated by the fact that fetch_pack() reports if it has performed a connectivity check itself, and if the transport supports connect or stateless-connect, it will bubble up that report so that "git fetch" knows not to perform the connectivity check in such a case. This was noticed when a user tried to deepen an existing repository by fetching with --no-shallow from a server that did not send all necessary objects - the connectivity check as run by "git fetch" succeeded, but a subsequent "git fsck" failed.

2018-07-03ref-filter: avoid backend filtering with --ignore-caseLibravatar Jeff King1-1/+1
When for-each-ref is used with --ignore-case, we expect match_name_as_path() to do a case-insensitive match. But there's an extra layer of filtering that happens before we even get there. Since commit cfe004a5a9 (ref-filter: limit traversal to prefix, 2017-05-22), we feed the prefix to the ref backend so that it can optimize the ref iteration. There's no mechanism for us to tell the backend we're matching case-insensitively. Nor is there likely to be one anytime soon, since the packed backend relies on binary-searching the sorted list of refs. Let's just punt on this case. The extra filtering is an optimization that we simply can't do. We'll still give the correct answer via the filtering in match_name_as_path().
