work better.

Allow "git rebase" to reapply all local commits, even if the may be
already in the upstream, without checking first.
* jt/rebase-allow-duplicate:
rebase --merge: optionally skip upstreamed commits
|
|
"git rebase" (again) learns to honor "--no-keep-empty", which lets
the user to discard commits that are empty from the beginning (as
opposed to the ones that become empty because of rebasing). The
interactive rebase also marks commits that are empty in the todo.
* en/rebase-no-keep-empty:
rebase: fix an incompatible-options error message
rebase: reinstate --no-keep-empty
rebase -i: mark commits that begin empty in todo editor

t: restrict `is_hidden` to be called only on Windows
mingw: make test_path_is_hidden more robust
t: consolidate the `is_hidden` functions
|
|
"git log" learned "--show-pulls" that helps pathspec limited
history views; a merge commit that takes the whole change from a
side branch, which is normally omitted from the output, is shown
in addition to the commits that introduce real changes.
* ds/revision-show-pulls:
revision: --show-pulls adds helpful merges
|

We've left the command line parsing of "git log :/a/b/" broken for
about a full year without anybody noticing, which has been
corrected.

repository: mark the "refs" pointer as private
sha1-name: do not assume that the ref store is initialized
|
|
The output from "git format-patch" uses RFC 2047 encoding for
non-ASCII letters on From: and Subject: headers, so that it can
directly be fed to e-mail programs. A new option has been added
to produce these headers in raw.
* eb/format-patch-no-encode-headers:
format-patch: teach --no-encode-email-headers

When fed a midx that records no objects, some codepaths tried to
loop from 0 through (num_objects-1), which, due to integer
arithmetic wrapping around, made it nonsense operation with out of

Since its introduction in 7249e91 (revision.c: support --notes
command-line option, 2011-03-29), combining '--notes' with any option
that causes us to format notes (e.g., '--pretty', '--format="%N"', etc)
results in a failed assertion at runtime.
$ git rev-list HEAD | git diff-tree --stdin --pretty=medium --notes
commit 8f3d9f354286745c751374f5f1fcafee6b3f3136
git: notes.c:1308: format_display_notes: Assertion `display_notes_trees' failed.
Aborted
This failure is due to diff-tree not calling 'load_display_notes' to
initialize the notes machinery.
Ordinarily, this failure isn't triggered, because it requires passing
both '--notes' and another of the above mentioned options. In the case
of '--pretty', for example, we set 'opt->verbose_header', causing
'show_log()' to eventually call 'format_display_notes()', which expects
a non-NULL 'display_note_trees'.
Without initializing the notes machinery, 'display_note_trees' remains
NULL, and thus triggers an assertion failure.
Fix this by initializing the notes machinery after parsing our options,
and harden this behavior against regression with a test in t4013. (Note
that the added ref in this test requires updating two unrelated tests
which use 'log --all', and thus need to learn about the new refs).

Git's URL parser interprets
https:///example.com/repo.git
to have no host and a path of "example.com/repo.git". Curl, on the
other hand, internally redirects it to https://example.com/repo.git. As
a result, until "credential: parse URL without host as empty host, not
unset", tricking a user into fetching from such a URL would cause Git to
send credentials for another host to example.com.
Teach fsck to block and detect .gitmodules files using such a URL to
prevent sharing them with Git versions that are not yet protected.
A relative URL in a .gitmodules file could also be used to trigger this.
The relative URL resolver used for .gitmodules does not normalize
sequences of slashes and can follow ".." components out of the path part
and to the host part of a URL, meaning that such a relative URL can be
used to traverse from a https://foo.example.com/innocent superproject to
a https:///attacker.example.com/exploit submodule. Fortunately,
redundant extra slashes in .gitmodules are rare, so we can catch this by
detecting one after a leading sequence of "./" and "../" components.

Until "credential: refuse to operate when missing host or protocol",
Git's credential handling code interpreted URLs with empty scheme to
mean "give me credentials matching this host for any protocol".
Luckily libcurl does not recognize such URLs (it tries to look for a
protocol named "" and fails). Just in case that changes, let's reject
them within Git as well. This way, credential_from_url is guaranteed to
always produce a "struct credential" with protocol and host set.

libcurl permits making requests without a URL scheme specified. In
this case, it guesses the URL from the hostname, so I can run
git ls-remote http::ftp.example.com/path/to/repo
and it would make an FTP request.
Any user intentionally using such a URL is likely to have made a typo.
Unfortunately, credential_from_url is not able to determine the host and
protocol in order to determine appropriate credentials to send, and
until "credential: refuse to operate when missing host or protocol",
this resulted in another host's credentials being leaked to the named
host.
Teach credential_from_url_gently to consider such a URL to be invalid
so that fsck can detect and block gitmodules files with such URLs,
allowing server operators to avoid serving them to downstream users
running older versions of Git.
This also means that when such URLs are passed on the command line, Git
will print a clearer error so affected users can switch to the simpler
URL that explicitly specifies the host and protocol they intend.
One subtlety: .gitmodules files can contain relative URLs, representing
a URL relative to the URL they were cloned from. The relative URL
resolver used for .gitmodules can follow ".." components out of the path
part and past the host part of a URL, meaning that such a relative URL
can be used to traverse from a https://foo.example.com/innocent
superproject to a https::attacker.example.com/exploit submodule.
Fortunately a leading ':' in the first path component after a series of
leading './' and '../' components is unlikely to show up in other
contexts, so we can catch this by detecting that pattern.
