Jonathan Nieder 40222792fa vcs-svn: remove more unused prototypes and declarations
I forgot to remove these in v1.7.10-rc0~118^2~4^2~5^2~4 (vcs-svn:
eliminate repo_tree structure, 2010-12-10).

This finishes what was started in commit 36f63b50 (vcs-svn: remove
unused prototypes, 2017-08-21).

Jonathan Tan 4a4becfb23 Doc: clarify that pack-objects makes packs, plural
The documentation for pack-objects describes that it creates "a packed
archive of objects", which is confusing because it may create multiple
packs if --max-pack-size is set. Update the documentation to clarify
this, and explaining in which cases such a feature would be useful.

Michael Haggerty 4ff0f01cb7 refs: retry acquiring reference locks for 100ms
The philosophy of reference locking has been, "if another process is
changing a reference, then whatever I'm trying to do to it will
probably fail anyway because my old-SHA-1 value is probably no longer
current". But this argument falls down if the other process has locked
the reference to do something that doesn't actually change the value
of the reference, such as `pack-refs` or `reflog expire`. There
actually *is* a decent chance that a planned reference update will
still be able to go through after the other process has released the
lock.

So when trying to lock an individual reference (e.g., when creating
"refs/heads/master.lock"), if it is already locked, then retry the
lock acquisition for approximately 100 ms before giving up. This
should eliminate some unnecessary lock conflicts without wasting a lot
of time.

Add a configuration setting, `core.filesRefLockTimeout`, to allow this
setting to be tweaked.

Note: the function `get_files_ref_lock_timeout_ms()` cannot be private
to the files backend because it is also used by `write_pseudoref()`
and `delete_pseudoref()`, which are defined in `refs.c` so that they
can be used by other reference backends.

Michael J Gruber 9d89b35526 merge: save merge state earlier
If the `git merge` process is killed while waiting for the editor to
finish, the merge state is lost but the prepared merge msg and tree is kept.
So, a subsequent `git commit` creates a squashed merge even when the
user asked for proper merge commit originally.

Demonstrate the problem with a test crafted after the in t7502. The test
requires EXECKEEPSPID (thus does not run under MINGW).

Save the merge state earlier (in the non-squash case) so that it does
not get lost. This makes the test pass.

Michael J Gruber 8e6a6bb360 merge: split write_merge_state in two
write_merge_state() writes out the merge heads, mode, and msg. But we
may want to write out heads, mode without the msg. So, split out heads
(+mode) into a separate function write_merge_heads() that is called by
write_merge_state().

No funtional change so far, except when these non-atomic writes are
interrupted: we write heads-mode-msg now when we used to write
heads-msg-mode.

Michael J Gruber 62dc42b937 merge: clarify call chain
prepare_to_commit() cannot be reached in the non-squash case:
It is called by merge_trivial() and finish_automerge() only, but the
calls to the latter are somewhat hard to track:

If option_commit is not set, the code in cmd_merge() uses a fake
conflict return code (ret=1) to avoid writing the tree, which also
avoids setting automerge_was_ok (just as in the proper ret==1 case), so
that finish_automerge() is not called.

To ensure that no code change breaks that assumption, safe-guard
prepare_to_commit() by a BUG() statement.

Junio C Hamano 6e96cb5286 rerere: allow approxidate in gc.rerereResolved/gc.rerereUnresolved
These two configuration variables are described in the documentation
to take an expiry period expressed in the number of days:

    gc.rerereResolved::
	    Records of conflicted merge you resolved earlier are
	    kept for this many days when 'git rerere gc' is run.
	    The default is 60 days.

    gc.rerereUnresolved::
	    Records of conflicted merge you have not resolved are
	    kept for this many days when 'git rerere gc' is run.
	    The default is 15 days.

There is no strong reason not to allow a more general "approxidate"
expiry specification, e.g. "5.days.ago", or "never".

Rename the config_get_expiry() helper introduced in the previous
step to git_config_get_expiry_in_days() and move it to a more
generic place, config.c, and use date.c::parse_expiry_date() to do
so.  Give it an ability to allow the caller to tell among three
cases (i.e. there is no "gc.rerereResolved" config, there is and it
is correctly parsed into the *expiry variable, and there was an
error in parsing the given value).  The current caller can work
correctly without using the return value, though.

In the future, we may find other variables that only allow an
integer that specifies "this many days" or other unit of time, and
when it happens we may need to drop "_days" suffix from the name of
the function and instead pass the "scale" value as another parameter.

But this will do for now.

Junio C Hamano 5ea82279c0 rerere: represent time duration in timestamp_t internally
The two configuration variables, gc.rerereResolved and
gc.rerereUnresolved, are measured in days and are passed as such
into the prune_one() helper function, which worked in time_t to see
if an entry in the rerere database is past its expiry.

Instead, have the caller turn the number of days into the expiry
timestamp.  Further, use timestamp_t instead of time_t.  This will
make it possible to extend the way the configuration variable is
spelled by using date.c::parse_expiry_date() that gives the expiry
timestamp in timestamp_t.

Junio C Hamano e579aaa64d t4200: parameterize "rerere gc" custom expiry test
The test creates a rerere database entry that is two days old, and
tries to expire with three different custom expiry configuration
(keep ones less than 5 days old, keep ones used less than 5 days
ago, and expire everything right now).

We'll be introducing a different way to spell the same "5 days" and
"right now" parameter in a later step; parameterize the test to make
it easier to test the new spelling when it happens.

Junio C Hamano c277344182 t4200: make "rerere gc" test more robust
The test blindly trusted that there may be _some_ entries left in
the rerere database, and used them by updating their timestamps to
see if the gc threshold variables are honoured correctly.  This
won't work if there is no entry in the database when the test
begins.

Instead, clear the rerere database, and populate it with a few known
entries (which are bogus, but for the purpose of testing "garbage
collection", it does not matter---we want to make sure we collect
old cruft, even if the files are corrupt rerere database entries),
and use them for the expiry test.

The "multiple identical conflicts" test counts the number of entries
in the rerere database after trying a handful of mergy operations

database to a known state, allowing the state left by previous tests
to trigger a false failure.  Make it robust by cleaning the database
before it starts.

Kevin Willford ce012deb98 read-cache: avoid allocating every ondisk entry when writing
When writing the index for each entry an ondisk struct will be
allocated and freed in ce_write_entry.  We can do better by
using a ondisk struct on the stack for each entry.

This is accomplished by using a stack ondisk_cache_entry_extended
outside looping through the entries in do_write_index.  Only the
fixed fields of this struct are used when writing and depending on
whether it is extended or not the flags2 field will be written.
The name field is not used and instead the cache_entry name field
is used directly when writing out the name.  Because ce_write is
using a buffer and memcpy to fill the buffer before flushing to disk,
we don't have to worry about doing multiple ce_write calls.

Running the p0007-write-cache.sh tests would save anywhere
between 3-7% when the index had over a million entries with no
performance degradation on small repos.
