Picking two versions of Git and running tests to make sure the
older one and the newer one interoperate happily has now become
possible.
* jk/interop-test:
t/interop: add test of old clients against modern git-daemon
t: add an interoperability test harness

Git v2.12 was shipped with an embarrassing breakage where various
operations that verify paths given from the user stopped dying when
seeing an issue, and instead later triggering segfault.
... and then to down to 'maint'.
* js/realpath-pathdup-fix:
real_pathdup(): fix callsites that wanted it to die on error
t1501: demonstrate NULL pointer access with invalid GIT_WORK_TREE
Code clean-up and a string truncation fix.
* mm/two-more-xstrfmt:
bisect_next_all: convert xsnprintf to xstrfmt
stop_progress_msg: convert xsnprintf to xstrfmt
The command-line parsing of "git log -L" copied internal data
structures using incorrect size on ILP32 systems.
* vn/line-log-memcpy-size-fix:
line-log: use COPY_ARRAY to fix mis-sized memcpy
The code to parse "git log -L..." command line was buggy when there
are many ranges specified with -L; overrun of the allocated buffer
has been fixed.
* ax/line-log-range-merge-fix:
line-log.c: prevent crash during union of too many ranges
The patch subcommand of "git add -i" was meant to have paths
selection prompt just like other subcommand, unlike "git add -p"
directly jumps to hunk selection. Recently, this was broken and
"add -i" lost the paths selection dialog, but it now has been
fixed.
* jk/add-i-patch-do-prompt:
add--interactive: fix missing file prompt for patch mode with "-i"
When a redirected http transport gets an error during the
redirected request, we ignored the error we got from the server,
and ended up giving a not-so-useful error message.
* jt/http-base-url-update-upon-redirect:
http: attempt updating base URL only if no error
Reduce authentication round-trip over HTTP when the server supports
just a single authentication method.
* jk/http-auth:
http: add an "auto" mode for http.emptyauth
http: restrict auth methods to what the server advertises
"git branch --list" takes the "--abbrev" and "--no-abbrev" options
to control the output of the object name in its "-v"(erbose)
output, but a recent update started ignoring them; this fixes it
before the breakage reaches to any released version.
* kn/ref-filter-branch-list:
branch: honor --abbrev/--no-abbrev in --list mode
"git push" had a handful of codepaths that could lead to a deadlock
when unexpected error happened, which has been fixed.
* jk/push-deadlock-regression-fix:
send-pack: report signal death of pack-objects
send-pack: read "unpack" status even on pack-objects failure
send-pack: improve unpack-status error messages
send-pack: use skip_prefix for parsing unpack status
send-pack: extract parsing of "unpack" response
receive-pack: fix deadlock when we cannot create tmpdir
Recent versions of Git treats http alternates (used in dumb http
transport) just like HTTP redirects and requires the client to
enable following it, due to security concerns. But we forgot to
give a warning when we decide not to honor the alternates.
* ew/http-alternates-as-redirects-warning:
http: release strbuf on disabled alternates
http: inform about alternates-as-redirects behavior
"git filter-branch --prune-empty" drops a single-parent commit that
becomes a no-op, but did not drop a root commit whose tree is empty.
* dp/filter-branch-prune-empty:
p7000: add test for filter-branch with --prune-empty
filter-branch: fix --prune-empty on parentless commits
t7003: ensure --prune-empty removes entire branch when applicable
t7003: ensure --prune-empty can prune root commit
The t/perf performance test suite was not prepared to test not so
old versions of Git, but now it covers versions of Git that are not
so ancient.
* jt/perf-updates:
t/perf: add fallback for pre-bin-wrappers versions of git
t/perf: use $MODERN_GIT for all repo-copying steps
t/perf: export variable used in other blocks
"git fetch" that requests a commit by object name, when the other
side does not allow such an request, failed without much
explanation.
* mm/fetch-show-error-message-on-unadvertised-object:
fetch-pack: add specific error for fetching an unadvertised object
fetch_refs_via_pack: call report_unmatched_refs
fetch-pack: move code to report unmatched refs to a function
"git branch @" created refs/heads/@ as a branch, and in general the
code that handled @{-1} and @{upstream} was a bit too loose in
disambiguating.
* jk/interpret-branch-name:
checkout: restrict @-expansions when finding branch
strbuf_check_ref_format(): expand only local branches
branch: restrict @-expansions when deleting
t3204: test git-branch @-expansion corner cases
interpret_branch_name: allow callers to restrict expansions
strbuf_branchname: add docstring
strbuf_branchname: drop return value
interpret_branch_name: move docstring to header file
interpret_branch_name(): handle auto-namelen for @{-1}
A few tests were run conditionally under (rare) conditions where
they cannot be run (like running cvs tests under 'root' account).
* ab/cond-skip-tests:
gitweb tests: skip tests when we don't have Time::HiRes
gitweb tests: change confusing "skip_all" phrasing
cvs tests: skip tests that call "cvs commit" when running as root
"git diff --quiet" relies on the size field in diff_filespec to be
correctly populated, but diff_populate_filespec() helper function
made an incorrect short-cut when asked only to populate the size
field for paths that need to go through convert_to_git() (e.g. CRLF
conversion).
* jc/diff-populate-filespec-size-only-fix:
diff: do not short-cut CHECK_SIZE_ONLY check in diff_populate_filespec()
The command-line parsing of "git log -L" copied internal data
structures using incorrect size on ILP32 systems.
* vn/line-log-memcpy-size-fix:

are many ranges specified with -L; overrun of the allocated buffer
has been fixed.
* ax/line-log-range-merge-fix:
line-log.c: prevent crash during union of too many ranges
There is no need for Python only to give a few messages to the
standard error stream, but we somehow did.
* ss/remote-bzr-hg-placeholder-wo-python:
contrib: git-remote-{bzr,hg} placeholders don't need Python

All callers of add_blame_entry() allocate and copy the second argument.
Let the function do it for them, reducing code duplication.

This test just checks that old clients can clone and fetch
from a newer git-daemon. The opposite should also be true,
but it's hard to test ancient versions of git-daemon because
they lack basic options like "--listen".
Note that we have to make a slight tweak to the
lib-git-daemon helper from the regular tests, so that it
starts the daemon with our correct git.a version.

The current test suite is good at letting you test a
particular version of Git. But it's not very good at letting
you test _two_ versions and seeing how they interact (e.g.,
one cloning from the other).
This commit adds a test harness that will build two
arbitrary versions of git and make it easy to call them from
inside your tests. See the README and the example script for
details.

"git stash save" takes a pathspec so that the local changes can be
stashed away only partially.
* tg/stash-push:
stash: allow pathspecs in the no verb form
stash: use stash_push for no verb form
stash: teach 'push' (and 'create_stash') to honor pathspec
stash: refactor stash_create
stash: add test for the create command line arguments
stash: introduce push verb
When "git submodule init" decides that the submodule in the working
tree is its upstream, it now gives a warning as it is not a very
common setup.

"Cc:" on the trailer part does not have to conform to RFC strictly,
unlike in the e-mail header. "git send-email" has been updated to
ignore anything after '>' when picking addresses, to allow non-address
cruft like " # stable 4.4" after the address.
* jh/send-email-one-cc:
send-email: only allow one address per body tag
An helper function to make it easier to append the result from
real_path() to a strbuf has been added.
* rs/strbuf-add-real-path:
strbuf: add strbuf_add_real_path()
cocci: use ALLOC_ARRAY
A leak in a codepath to read from a packed object in (rare) cases
has been plugged.
* rs/sha1-file-plug-fallback-base-leak:
sha1_file: release fallback base's memory in unpack_entry()
