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.

This patch broadens the set of commits matched by ":/<pattern>" to include commits reachable from HEAD but not any named ref. This avoids surprising behavior when working with a detached HEAD and trying to refer to a commit that was recently created and only exists within the detached state. If multiple worktrees exist, only the current worktree's HEAD is considered reachable. This is consistent with the existing behavior for other per-worktree refs: e.g., bisect refs are considered reachable, but only within the relevant worktree.

2018-07-12t/lib-httpd: avoid occasional failures when checking access.logLibravatar SZEDER Gábor4-8/+16
The last test of 't5561-http-backend.sh', 'server request log matches test results' may fail occasionally, because the order of entries in Apache's access log doesn't match the order of requests sent in the previous tests, although all the right requests are there. I saw it fail on Travis CI five times in the span of about half a year, when the order of two subsequent requests was flipped, and could trigger the failure with a modified Git. However, I was unable to trigger it with stock Git on my machine. Three tests in 't5541-http-push-smart.sh' and 't5551-http-fetch-smart.sh' check requests in the log the same way, so they might be prone to a similar occasional failure as well. When a test sends a HTTP request, it can continue execution after 'git-http-backend' fulfilled that request, but Apache writes the corresponding access log entry only after 'git-http-backend' exited. Some time inevitably passes between fulfilling the request and writing the log entry, and, under unfavourable circumstances, enough time might pass for the subsequent request to be sent and fulfilled by a different Apache thread or process, and then Apache writes access log entries racily. This effect can be exacerbated by adding a bit of variable delay after the request is fulfilled but before 'git-http-backend' exits, e.g. like this: diff --git a/http-backend.c b/http-backend.c index f3dc218b2..bbf4c125b 100644 --- a/http-backend.c +++ b/http-backend.c @@ -709,5 +709,7 @@ int cmd_main(int argc, const char **argv) max_request_buffer); cmd->imp(&hdr, cmd_arg); + if (getpid() % 2) + sleep(1); return 0; } This delay considerably increases the chances of log entries being written out of order, and in turn makes t5561's last test fail almost every time. Alas, it doesn't seem to be enough to trigger a similar failure in t5541 and t5551. So, since we can't just rely on the order of access log entries always corresponding the order of requests, make checking the access log more deterministic by sorting (simply lexicographically) both the stripped access log entries and the expected entries before the comparison with 'test_cmp'. This way the order of log entries won't matter and occasional out-of-order entries won't trigger a test failure, but the comparison will still notice any unexpected or missing log entries. OTOH, this sorting will make it harder to identify from which test an unexpected log entry came from or which test's request went missing. Therefore, in case of an error include the comparison of the unsorted log enries in the test output as well. And since all this should be performed in four tests in three test scripts, put this into a new helper function 'check_access_log' in 't/lib-httpd.sh'.

2018-07-12t5541: clean up truncating access logLibravatar SZEDER Gábor1-8/+4
In the second test of 't5541-http-push-smart.sh', 'no empty path components' we truncate Apache's access log by running: echo >.../access.log There are two issues with this approach: - This doesn't leave an empty file behind, like a proper truncation would, but a file with a lone newline in it. Consequently, a later test checking the log's contents must consider this improper truncation and include an empty line in the expected content. - This truncation is done in the middle of the test, because, quoting the in-code comment, "we do this [truncation] before the actual comparison to ensure the log is cleared" even when subsequent 'test_cmp' fails. Alas, this is not quite robust enough, as it is conceivable that 'git clone' fails after already having sent a request, in which case the access log would not be truncated and would leave stray log entries behind. Since there is no need for that newline at all, drop the 'echo' from the truncation and adjust the expected content accordingly. Furthermore, make sure that the truncation is performed no matter whether and how 'git clone' fails unexpectedly by specifying it as a 'test_when_finished' command.

2018-07-11has_uncommitted_changes(): fall back to empty treeLibravatar Jeff King1-0/+12
If has_uncommitted_changes() can't resolve HEAD (e.g., because it's unborn or corrupt), then we end up calling run_diff_index() with an empty revs.pending array. This causes a segfault, as run_diff_index() blindly looks at the first pending item. Fixing this raises a question of fault: should run_diff_index() handle this case, or is the caller wrong to pass an empty pending list? Looking at the other callers of run_diff_index(), they handle this in one of three ways: - they resolve the object themselves, and avoid doing the diff if it's not valid - they resolve the object themselves, and fall back to the empty tree - they use setup_revisions(), which will die() if the object isn't valid Since this is the only broken caller, that argues that the fix should go there. Falling back to the empty tree makes sense here, as we'd claim uncommitted changes if and only if the index is non-empty. This may be a little funny in the case of corruption (the corrupt HEAD probably _isn't_ empty), but: - we don't actually know the reason here that HEAD didn't resolve (the much more likely case is that we have an unborn HEAD, in which case the empty tree comparison is the right thing) - this matches how other code, like "git diff", behaves While we're thinking about it, let's add an assertion to run_diff_index(). It should always be passed a single object, and as this bug shows, it's easy to get it wrong (and an assertion is easier to hunt down than a segfault, or a quietly ignored extra tree).

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.

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.

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>
2018-07-06t6036: add lots of detail for directory/file conflicts in recursive caseLibravatar Elijah Newren1-55/+201
There was a discussion of problematic directory/file conflicts with virtual merge bases on the mailing list years ago at https://public-inbox.org/git/AANLkTimwUQafGDrjxWrfU9uY1uKoFLJhxYs=vssOPqdf@mail.gmail.com/ Part of these corresponding tests made it into this testsuite. However, the more problematic one didn't. And there are others that showcase the problems even more. Add a very lengthy explanation, some of it from that email, describing the tradeoffs in picking a recursive merge-base when you're dealing with an add/add directory/file conflict. The solution picked years ago is relatively good, but there is the potential to do even better, assuming we're willing to pay a certain performance cost.

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.
