The test linter has been taught that we do not like "echo -e".
* tb/test-lint-echo-e:
test-lint: echo -e (or -E) is not portable
|

Code clean-up that also plugs memory leaks.
* jk/revision-remove-cmdline-pathspec:
pathspec doc: parse_pathspec does not maintain references to args
revision: replace "struct cmdline_pathspec" with argv_array

The scripts to drive TravisCI has been reorganized and then an
optimization to avoid spending cycles on a branch whose tip is
tagged has been implemented.
* ls/travis-scriptify:
travis-ci: fix "skip_branch_tip_with_tag()" string comparison
travis: dedent a few scripts that are indented overly deeply
travis-ci: skip a branch build if equal tag is present
travis-ci: move Travis CI code into dedicated scripts

"git gc" tries to avoid running two instances at the same time by
reading and writing pid/host from and to a lock file; it used to
use an incorrect fscanf() format when reading, which has been
corrected.
* aw/gc-lockfile-fscanf-fix:
gc: call fscanf() with %<len>s, not %<len>c, when reading hostname

A test to demonstrate "git mv" failing to adjust nested submodules
has been added.
* hv/mv-nested-submodules-test:
add test for bug in git-mv for recursive submodules

"make style" runs git-clang-format to help developers by pointing
out coding style issues.
* bw/git-clang-format:
Makefile: add style build rule
clang-format: outline the git project's coding style

"git imap-send" has our own implementation of the protocol and also
can use more recent libCurl with the imap protocol support. Update
the latter so that it can use the credential subsystem, and then
make it the default option to use, so that we can eventually
deprecate and remove the former.
* nm/imap-send-with-curl:
imap-send: use curl by default when possible
imap_send: setup_curl: retreive credentials if not set in config file
imap-send: add wrapper to get server credentials if needed
imap-send: return with error if curl failed

The explanation of the cut-line in the commit log editor has been
slightly tweaked.
* ks/commit-do-not-touch-cut-line:

API error-proofing which happens to also squelch warnings from GCC.
* tg/refs-allowed-flags:
refs: strip out not allowed flags from ref_transaction_update

"git archive", especially when used with pathspec, stored an empty
directory in its output, even though Git itself never does so.
This has been fixed.
* rs/archive-excluded-directory:
archive: don't add empty directories to archives
|

"git help co" now says "co is aliased to ...", not "git co is".
* ks/help-alias-label:
help: change a message to be more precise

Step #0 of a planned & larger series to make the in-core object
store per in-core repository object.
* jn/per-repo-object-store-fixes:
replace-objects: evaluate replacement refs without using the object store
push, fetch: error out for submodule entries not pointing to commits
pack: make packed_git_mru global a value instead of a pointer
|

Many codepaths did not diagnose write failures correctly when disks
go full, due to their misuse of write_in_full() helper function,
which have been corrected.
* jk/write-in-full-fix:
read_pack_header: handle signed/unsigned comparison in read result
config: flip return value of store_write_*()
notes-merge: use ssize_t for write_in_full() return value
pkt-line: check write_in_full() errors against "< 0"
convert less-trivial versions of "write_in_full() != len"
avoid "write_in_full(fd, buf, len) != len" pattern
get-tar-commit-id: check write_in_full() return against 0
config: avoid "write_in_full(fd, buf, len) < len" pattern

A handful of tests to demonstrates a recursive implementation of
"name-rev" hurts.
* mg/name-rev-tests-with-short-stack:
t6120: test describe and name-rev with deep repos
t6120: clean up state after breaking repo
t6120: test name-rev --all and --stdin
t7004: move limited stack prereq to test-lib

The command line arguments passed to main() are valid for the life of
a program, but the same is not true for all other argv-style arrays
(e.g. when a caller creates an argv_array). Clarify that
parse_pathspec does not rely on the argv passed to it to remain valid.
This makes it easier to tell that callers like "git rev-list --stdin"
are safe and ensures that that is more likely to remain true as the
implementation of parse_pathspec evolves.

Many of our programs consider that it is OK to release dynamic
storage that is used throughout the life of the program by simply
exiting, but this makes it harder to leak detection tools to avoid
reporting false positives. Plug many existing leaks and introduce
a mechanism for developers to mark that the region of memory
pointed by a pointer is not lost/leaking to help these tools.
* jk/leak-checkers:
git-compat-util: make UNLEAK less error-prone

We assemble an array of strings in a custom struct,
NULL-terminate the result, and then pass it to
parse_pathspec().
But then we never free the array or the individual strings
(nor can we do the latter, as they are heap-allocated when
they come from stdin but not when they come from the
passed-in argv).
Let's swap this out for an argv_array. It does the same
thing with fewer lines of code, and it's safe to call
argv_array_clear() at the end to avoid a memory leak.

Some implementations of `echo` support the '-e' option to enable
backslash interpretation of the following string.
As an addition, they support '-E' to turn it off.
However, none of these are portable, POSIX doesn't even mention them,
and many implementations don't support them.
A check for '-n' is already done in check-non-portable-shell.pl,
extend it to cover '-n', '-e' or '-E'.

Commit 0e5bba5 ("add UNLEAK annotation for reducing leak false
positives", 2017-09-08) introduced an UNLEAK macro to be used as
"UNLEAK(var);", but its existing definitions leave semicolons that act
as empty statements, which will lead to syntax errors, e.g.
if (condition)
UNLEAK(var);
else
something_else(var);
would be broken with two statements between if (condition) and else.
Lose the excess semicolon from the end of the macro replacement text.

Earlier in this codepath, we (ab)used "%<len>c" to read the hostname
recorded in the lockfile into locking_host[HOST_NAME_MAX + 1] while
substituting <len> with the actual value of HOST_NAME_MAX.
This turns out to be incorrect, as it is an instruction to read
exactly the specified number of bytes. Because we are trying to
read at most that many bytes, we should be using "%<len>s" instead.

When using git-mv with a submodule it will detect that and update the
paths for its configurations (.gitmodules, worktree and gitfile). This
does not work for recursive submodules where a user renames the root
submodule.
We discovered this fact when working on on-demand fetch for renamed
submodules. Lets add a test to document.
