215b565126 for-each-ref: introduce new structures for better organisation
Introduce 'ref_filter_cbdata' which will hold 'ref_filter'
(conditions to filter the refs on) and 'ref_array' (the array
of ref_array_items). Modify the code to use these new structures.

This is a preparatory patch to eventually move code from 'for-each-ref'
to 'ref-filter' and make it publicly available.

5879232090 for-each-ref: rename 'refinfo' to 'ref_array_item'
Rename 'refinfo' to 'ref_array_item' as a preparatory step for
introduction of new structures in the forthcoming patch.

Re-order the fields in 'ref_array_item' so that refname can be
eventually converted to a FLEX_ARRAY.

ed01e206ba for-each-ref: extract helper functions out of grab_single_ref()
Extract two helper functions out of grab_single_ref(). Firstly,
new_refinfo() which is used to allocate memory for a new refinfo
structure and copy the objectname, refname and flag to it.
Secondly, match_name_as_path() which when given an array of patterns
and the refname checks if the refname matches any of the patterns
given while the pattern is a pathname, also supports wildcard
characters.

This is a preperatory patch for restructuring 'for-each-ref' and
eventually moving most of it to 'ref-filter' to provide the
functionality to similar commands via public API's.

58d121b22b Allow to control where the replace refs are looked for
It can be useful to have grafts or replace refs for specific use-cases while
keeping the default "view" of the repository pristine (or with a different
set of grafts/replace refs).

It is possible to use a different graft file with GIT_GRAFT_FILE, but while
replace refs are more powerful, they don't have an equivalent override.

Add a GIT_REPLACE_REF_BASE environment variable to control where git is
going to look for replace refs.

0eeb077be7 index-pack: avoid excessive re-reading of pack directory
Since 45e8a74 (has_sha1_file: re-check pack directory before
giving up, 2013-08-30), we spend extra effort for
has_sha1_file to give the right answer when somebody else is
repacking. Usually this effort does not matter, because
after finding that the object does not exist, the next step
is usually to die().

However, some code paths make a large number of
has_sha1_file checks which are _not_ expected to return 1.
The collision test in index-pack.c is such a case. On a
local system, this can cause a performance slowdown of
around 5%. But on a system with high-latency system calls
(like NFS), it can be much worse.

This patch introduces a "quick" flag to has_sha1_file which
callers can use when they would prefer high performance at
the cost of false negatives during repacks. There may be
other code paths that can use this, but the index-pack one
is the most obviously critical, so we'll start with
switching that one.

f0e7f11d05 index-pack: fix truncation of off_t in comparison
Commit c6458e6 (index-pack: kill union delta_base to save
memory, 2015-04-18) refactored the comparison functions used
in sorting and binary searching our delta list. The
resulting code does something like:

  int cmp_offsets(off_t a, off_t b)
  {
	  return a - b;
  }

This works most of the time, but produces nonsensical
results when the difference between the two offsets is
larger than what can be stored in an "int". This can lead to
unresolved deltas if the packsize is larger than 2G (even on
64-bit systems, an int is still typically 32 bits):

  $ git clone git://github.com/mozilla/gecko-dev
  Cloning into 'gecko-dev'...
  remote: Counting objects: 4800161, done.
  remote: Compressing objects: 100% (178/178), done.
  remote: Total 4800161 (delta 88), reused 0 (delta 0), pack-reused 4799978
  Receiving objects: 100% (4800161/4800161), 2.21 GiB | 3.26 MiB/s, done.
  Resolving deltas:  99% (3808820/3811944), completed with 0 local objects.
  fatal: pack has 3124 unresolved deltas
  fatal: index-pack failed

We can fix it by doing direct comparisons between the
offsets and returning constants; the callers only care about
the sign of the comparison, not the magnitude.

8afc493d11 for-each-ref: report broken references correctly
If there is a loose reference file with invalid contents, "git
for-each-ref" incorrectly reports the problem as being a missing
object with name NULL_SHA1:

    $ echo '12345678' >.git/refs/heads/nonsense
    $ git for-each-ref
    fatal: missing object 0000000000000000000000000000000000000000 for refs/heads/nonsense

With an explicit "--format" string, it can even report that the
reference validly points at NULL_SHA1:

    $ git for-each-ref --format='%(objectname) %(refname)'
    0000000000000000000000000000000000000000 refs/heads/nonsense
    $ echo $?
    0

This has been broken since

    b7dd2d2 for-each-ref: Do not lookup objects when they will not be used (2009-05-27)

, which changed for-each-ref from using for_each_ref() to using
git_for_each_rawref() in order to avoid looking up the referred-to
objects unnecessarily. (When "git for-each-ref" is given a "--format"
string that doesn't include information about the pointed-to object,
it does not look up the object at all, which makes it considerably
faster. Iterating with DO_FOR_EACH_INCLUDE_BROKEN is essential to this
optimization because otherwise for_each_ref() would itself need to
check whether the object exists as part of its brokenness test.)

But for_each_rawref() includes broken references in the iteration, and
"git for-each-ref" doesn't itself reject references with REF_ISBROKEN.
The result is that broken references are processed *as if* they had
the value NULL_SHA1, which is the value stored in entries for broken
references.

Change "git for-each-ref" to emit warnings for references that are
REF_ISBROKEN but to otherwise skip them.

9b7a61d7da format-patch: do not feed tags to clear_commit_marks()
"git format-patch --ignore-if-in-upstream A..B", when either A or B
is a tag, failed miserably.

This is because the code passes the tips it used for traversal to
clear_commit_marks(), after running a temporary revision traversal
to enumerate the commits on both branches to find if they have
commits that make equivalent changes.  The revision traversal
machinery knows how to enumerate commits reachable starting from a
tag, but clear_commit_marks() wants to take nothing but a commit.

In the longer term, it might be a more correct fix to teach
clear_commit_marks() to do the same "committish to commit"
dereferencing that is done in the revision traversal machinery,
but for now this fix should suffice.

2b2a5be394 each_ref_fn: change to take an object_id parameter
Change typedef each_ref_fn to take a "const struct object_id *oid"
parameter instead of "const unsigned char *sha1".

To aid this transition, implement an adapter that can be used to wrap
old-style functions matching the old typedef, which is now called
"each_ref_sha1_fn"), and make such functions callable via the new
interface. This requires the old function and its cb_data to be
wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be
used as the cb_data for an adapter function, each_ref_fn_adapter().

This is an enormous diff, but most of it consists of simple,
mechanical changes to the sites that call any of the "for_each_ref"
family of functions. Subsequent to this change, the call sites can be
rewritten one by one to use the new interface.

979cb245e2 remote.c: return upstream name from stat_tracking_info
After calling stat_tracking_info, callers often want to
print the name of the upstream branch (in addition to the
tracking count). To do this, they have to access
branch->merge->dst[0] themselves. This is not wrong, as the
return value from stat_tracking_info tells us whether we
have an upstream branch or not. But it is a bit leaky, as we
make an assumption about how it calculated the upstream
name.

Instead, let's add an out-parameter that lets the caller
know the upstream name we found.

As a bonus, we can get rid of the unusual tri-state return
from the function. We no longer need to use it to
differentiate between "no tracking config" and "tracking ref
does not exist" (since you can check the upstream_name for
that), so we can just use the usual 0/-1 convention for
success/error.

3a429d0af3 remote.c: report specific errors from branch_get_upstream
When the previous commit introduced the branch_get_upstream
helper, there was one call-site that could not be converted:
the one in sha1_name.c, which gives detailed error messages
for each possible failure.

Let's teach the helper to optionally report these specific
errors. This lets us convert another callsite, and means we
can use the helper in other locations that want to give the
same error messages.

The logic and error messages come straight from sha1_name.c,
with the exception that we start each error with a lowercase
letter, as is our usual style (note that a few tests need
updated as a result).

9e3751d443 remote.c: drop "remote" pointer from "struct branch"
When we create each branch struct, we fill in the
"remote_name" field from the config, and then fill in the
actual "remote" field (with a "struct remote") based on that
name. However, it turns out that nobody really cares about
the latter field. The only two sites that access it at all
are:

  1. git-merge, which uses it to notice when the branch does
     not have a remote defined. But we can easily replace this
     with looking at remote_name instead.

  2. remote.c itself, when setting up the @{upstream} merge
     config. But we don't need to save the "remote" in the
     "struct branch" for that; we can just look it up for
     the duration of the operation.

So there is no need to have both fields; they are redundant
with each other (the struct remote contains the name, or you
can look up the struct from the name). It would be nice to
simplify this, especially as we are going to add matching
pushremote config in a future patch (and it would be nice to
keep them consistent).

So which one do we keep and which one do we get rid of?

If we had a lot of callers accessing the struct, it would be
more efficient to keep it (since you have to do a lookup to
go from the name to the struct, but not vice versa). But we
don't have a lot of callers; we have exactly one, so
efficiency doesn't matter. We can decide this based on
simplicity and readability.

And the meaning of the struct value is somewhat unclear. Is
it always the remote matching remote_name? If remote_name is
NULL (i.e., no per-branch config), does the struct fall back
to the "origin" remote, or is it also NULL? These questions
will get even more tricky with pushremotes, whose fallback
behavior is more complicated. So let's just store the name,
which pretty clearly represents the branch.*.remote config.
Any lookup or fallback behavior can then be implemented in
helper functions.

822f0c4ff7 clone: call transport_set_verbosity before anything else on the newly created transport
Commit 2879bc3 made the progress and verbosity options sent to remote helper
earlier than they previously were. But nothing else after that would send
updates if the value is changed later on with transport_set_verbosity.

While for fetch and push, transport_set_verbosity is the first thing that
is done after creating the transport, it was not the case for clone. So
commit 2879bc3 broke changing progress and verbosity for clone, for urls
requiring a remote helper only (so, not git:// urls, for instance).

Moving transport_set_verbosity to just after the transport is created
works around the issue.

7886cfa080 bundle: verify arguments more strictly
The `verify` and `create` subcommands of the bundle builtin do
not properly verify the command line arguments that have been
passed in. While the `verify` subcommand accepts an arbitrary
amount of ignored arguments the `create` subcommand does not
complain about being passed too few arguments, resulting in a
bogus call to `git rev-list`. Fix these errors by verifying that
the correct amount of arguments has been passed in.

"hash-object" learned in 5ba9a93 (hash-object: add --literally
option, 2014-09-11) to allow crafting a corrupt/broken object of

When the user-provided type is particularly long, however, it can
overflow the relatively small stack-based character array handed to
write_sha1_file_prepare() by hash_sha1_file() and write_sha1_file(),
leading to stack corruption (and crash).  Introduce a custom helper
to allow arbitrarily long typenames just for "hash-object --literally".

I rewrote it to avoid penalizing the non-literally code. Bugs are mine]

95d621217a config: use error() instead of fprintf(stderr, ...)
The die() / error() / warning() helpers put a fatal: / error: /
warning: prefix in front of the error message they print describing
the message's severity, which users are likely to be accustomed to
seeing these days.

This change will also be useful when marking the message for
translation: the argument to error() includes no newline at the end,
so it is less fussy for translators to translate without lines running
together in the translated output.

While we're here, start the error messages with a lowercase letter to
match the usual typography of error messages.

A quick web search and a code search at codesearch.debian.net finds no
scripts trying to parse these error messages, so this change should be
safe.

4bf256d67a blame: CRLF in the working tree and LF in the repo
A typical setup under Windows is to set core.eol to CRLF, and text
files are marked as "text" in .gitattributes, or core.autocrlf is
set to true.

After 4d4813a5 "git blame" no longer works as expected for such a
set-up.  Every line is annotated as "Not Committed Yet", even though
the working directory is clean.  This is because the commit removed
the conversion in blame.c for all files, with or without CRLF in the
repo.

Having files with CRLF in the repo and core.autocrlf=input is a
temporary situation, and the files, if committed as is, will be
normalized in the repo, which _will_ be a notable change.  Blaming
them with "Not Committed Yet" is the right result.  Revert commit
4d4813a5 which was a misguided attempt to "solve" a non-problem.

Add two test cases in t8003 to verify the correct CRLF conversion.

d45366e8aa merge: deprecate 'git merge <message> HEAD <commit>' syntax
We had this in "git merge" manual for eternity:

    'git merge' <msg> HEAD <commit>...

    [This] syntax (<msg> `HEAD` <commit>...) is supported for
    historical reasons.  Do not use it from the command line or in
    new scripts.  It is the same as `git merge -m <msg> <commit>...`.

With the update to "git merge" to make it understand what is
recorded in FETCH_HEAD directly, including Octopus merge cases, we
now can rewrite the use of this syntax in "git pull" with a simple
"git merge FETCH_HEAD".

Also there are quite a few fallouts in the test scripts, and it
turns out that "git cvsimport" also uses this old syntax to record
a merge.

Judging from this result, I would not be surprised if dropping the
support of the old syntax broke scripts people have written and been
relying on for the past ten years.  But at least we can start the
deprecation process by throwing a warning message when the syntax is
used.

With luck, we might be able to drop the support in a few years.

74e8bc59cb merge: handle FETCH_HEAD internally
The collect_parents() function now is responsible for

 1. parsing the commits given on the command line into a list of
    commits to be merged;

 2. filtering these parents into independent ones; and

 3. optionally calling fmt_merge_msg() via prepare_merge_message()
    to prepare an auto-generated merge log message, using fake
    contents that FETCH_HEAD would have had if these commits were
    fetched from the current repository with "git pull . $args..."

Make "git merge FETCH_HEAD" to be the same as the traditional

    git merge "$(git fmt-merge-msg <.git/FETCH_HEAD)" $commits

invocation of the command in "git pull", where $commits are the ones
that appear in FETCH_HEAD that are not marked as not-for-merge, by
making it do a bit more, specifically:

 - noticing "FETCH_HEAD" is the only "commit" on the command line
   and picking the commits that are not marked as not-for-merge as
   the list of commits to be merged (substitute for step #1 above);

 - letting the resulting list fed to step #2 above;

 - doing the step #3 above, using the contents of the FETCH_HEAD
   instead of fake contents crafted from the list of commits parsed
   in the step #1 above.

Note that this changes the semantics.  "git merge FETCH_HEAD" has
always behaved as if the first commit in the FETCH_HEAD file were
directly specified on the command line, creating a two-way merge
whose auto-generated merge log said "merge commit xyz".  With this
change, if the previous fetch was to grab multiple branches (e.g.
"git fetch $there topic-a topic-b"), the new world order is to
create an octopus, behaving as if "git pull $there topic-a topic-b"
were run.  This is a deliberate change to make that happen, and
can be seen in the changes to t3033 tests.

0b10b8a3d5 merge: clarify collect_parents() logic
Clarify this small function in three ways.

 - The function initially collects all commits to be merged into a
   commit_list "remoteheads"; the "remotes" pointer always points at
   the tail of this list (either the remoteheads variable itself, or
   the ->next slot of the element at the end of the list) to help
   elongate the list by repeated calls to commit_list_insert().
   Because the new element appended by commit_list_insert() will
   always have its ->next slot NULLed out, there is no need for us
   to assign NULL to *remotes to terminate the list at the end.

 - The variable "head_subsumed" always confused me every time I read
   this code.  What is happening here is that we inspect what the
   caller told us to merge (including the current HEAD) and come up
   with the list of parents to be recorded for the resulting merge
   commit, omitting commits that are ancestor of other commits.
   This filtering may remove the current HEAD from the resulting
   parent list---and we signal that fact with this variable, so that
   we can later record it as the first parent when "--no-ff" is in
   effect.

 - The "parents" list is created for this function by reduce_heads()
   and was not deallocated after its use, even though the loop
   control was written in such a way to allow us to do so by taking
   the "next" element in a separate variable so that it can be used
   in the next-step part of the loop control.

c6458e60ed index-pack: kill union delta_base to save memory
Once we know the number of objects in the input pack, we allocate an
array of nr_objects of struct delta_entry. On x86-64, this struct is
32 bytes long. The union delta_base, which is part of struct
delta_entry, provides enough space to store either ofs-delta (8 bytes)
or ref-delta (20 bytes).

Because ofs-delta encoding is more efficient space-wise and more
performant at runtime than ref-delta encoding, Git packers try to use
ofs-delta whenever possible, and it is expected that objects encoded
as ref-delta are minority.

In the best clone case where no ref-delta object is present, we waste
(20-8) * nr_objects bytes because of this union. That's about 38MB out
of 100MB for deltas[] with 3.4M objects, or 38%. deltas[] would be
around 62MB without the waste.

This patch attempts to eliminate that. deltas[] array is split into
two: one for ofs-delta and one for ref-delta. Many functions are also
duplicated because of this split. With this patch, ofs_deltas[] array
takes 51MB. ref_deltas[] should remain unallocated in clone case (0
bytes). This array grows as we see ref-delta. We save about half in
this case, or 25% of total bookkeeping.

The saving is more than the calculation above because some padding in
the old delta_entry struct is removed. ofs_delta_entry is 16 bytes,
including the 4 bytes padding. That's 13MB for padding, but packing
the struct could break platforms that do not support unaligned
access. If someone on 32-bit is really low on memory and only deals
with packs smaller than 2G, using 32-bit off_t would eliminate the
padding and save 27MB on top.

A note about ofs_deltas allocation. We could use ref_deltas memory
allocation strategy for ofs_deltas. But that probably just adds more
overhead on top. ofs-deltas are generally the majority (1/2 to 2/3) in
any pack. Incremental realloc may lead to too many memcpy. And if we
preallocate, say 1/2 or 2/3 of nr_objects initially, the growth rate
of ALLOC_GROW() could make this array larger than nr_objects, wasting
more memory.

3d6bc9a763 Revert "merge: pass verbosity flag down to merge-recursive"
This reverts commit 2bf15a3330, whose
intention was good, but the verbosity levels used in merge-recursive
turns out to be rather uneven.  For example, a merge of two branches
with conflicting submodule updates used to report CONFLICT: output
with --quiet but no longer (which *is* desired), while the final
"Automatic merge failed; fix conflicts and then commit" message is
still shown even with --quiet (which *is* inconsistent).

Originally reported by Bryan Turner; it is too early to declare what
the concensus is, but it seems that we would need to level the
verbosity levels used in merge strategy backends before we can go
forward.  In the meantime, we'd revert to the old behaviour until

about commit(s) that might get lost.  It says "If you want to keep
them ..." even for only one commit.

Use Q_() to allow differentiating singular vs plural.

2bf15a3330 merge: pass verbosity flag down to merge-recursive
This makes "git merge --quiet" really quiet when we call
into merge-recursive.

Note that we can't just pass our flag down as-is; the two
parts of the code use different scales. We center at "0" as
normal for git-merge (with "--quiet" giving a negative
value), but merge-recursive uses "2" as its center.  This
patch passes a negative value to merge-recursive rather than
"1", though, as otherwise the user would have to use "-qqq"
to squelch all messages (but the downside is that the user
cannot distinguish between levels 0-2 if without resorting
to the GIT_MERGE_VERBOSITY variable).

We may want to review and renormalize the message severities
in merge-recursive, but that does not have to happen now.
This is at least in improvement in the sense that we are
respecting "--quiet" at all.

84ccad8dec init: don't set core.worktree when initializing /.git
If you create a git repository in the root directory with
"git init /", we erroneously write a core.worktree entry.
This isn't _wrong_, in the sense that it's OK to set
core.worktree when we don't need to. But it is unnecessarily
surprising if you later move the .git directory to another
path (which usually moves the relative working tree, but is
foiled if there is an explicit worktree set).

The problem is that we check whether core.worktree is
necessary by seeing if we can make the git_dir by
concatenating "/.git" onto the working tree. That would lead
to "//.git" in this instance, but we actually have "/.git"
(without the doubled slash).

We can fix this by special-casing the root directory. I also
split the logic out into its own function to make the
conditional a bit more readable (and used skip_prefix, which
I think makes it a little more obvious what is going on).

No tests, as we would need to be able to write to "/" to do
so. I did manually confirm that:

  sudo git init /
  cd /
  git rev-parse --show-toplevel
  git config core.worktree

still finds the top-level correctly (as "/"), and does not
set any core.worktree variable.

1a51b52422 push-to-deploy: allow pushing into an unborn branch and updating it
Setting receive.denycurrentbranch to updateinstead and pushing into
the current branch, when the working tree and the index is truly
clean, is supposed to reset the working tree and the index to match
the tree of the pushed commit.  This did not work when pushing into

The code that drives push-to-checkout hook needs no change, as the
interface is defined so that hook can decide what to do when the

since the beginning.

539d09c3b4 show-branch: show all local heads when only giving one rev along --topics
"git show-branch --topics <rev> <revs>..." displays ancestry graph, only
considering commits that are in all given revs, except the first one.

"git show-branch" displays ancestry graph for all local branches.

Unfortunately, "git show-branch --topics <rev>" only prints out the rev
info for the given rev, and nothing else, e.g.:

  $ git show-branch --topics origin/master
  [origin/master] Sync with 2.3.3

While there is an option to add all remote-tracking branches (-r), and
another to add all local+remote branches (-a), there is no option to add
only local branches. Adding such an option could be considered, but a
user would likely already expect that the above command line considers
the lack of rev other than for --topics as meaning all local branches,
like when there is no argument at all.

Moreover, when using -r and -a along with --topics, the first local or
remote-tracking branch, depending on alphabetic order is used instead of
the one given after --topics (any rev given on the command line is
actually simply ignored when either -r or -a is given). And if no rev is
given at all, the fact that the first alphetical branch is the base of
topics is probably not expected by users (Maybe --topics should always
require one rev on the command line?)

This change makes
  "show-branch --topics $rev"
act as
  "show-branch --topics $rev $(git for-each-ref refs/heads
                               --format='%(refname:short)')"

  "show-branch -r --topics $rev ..."

                                   --format='%(refname:short)')"
instead of

Add test 'not prune proper checkouts', which uses valid but expired

Modify test 'not prune recent checkouts' to remove the worktree before
pruning - link in worktrees still must survive. In older form it is

319b678a7b sha1_file: squelch "packfile cannot be accessed" warnings
When we find an object in a packfile index, we make sure we
can still open the packfile itself (or that it is already
open), as it might have been deleted by a simultaneous
repack. If we can't access the packfile, we print a warning
for the user and tell the caller that we don't have the
object (we can then look in other packfiles, or find a loose
version, before giving up).

The warning we print to the user isn't really accomplishing
anything, and it is potentially confusing to users. In the
normal case, it is complete noise; we find the object
elsewhere, and the user does not have to care that we racily
saw a packfile index that became stale. It didn't affect the
operation at all.

A possibly more interesting case is when we later can't find
the object, and report failure to the user. In this case the
warning could be considered a clue toward that ultimate
failure. But it's not really a useful clue in practice. We
wouldn't even print it consistently (since we are racing
with another process, we might not even see the .idx file,
or we might win the race and open the packfile, completing
the operation).

This patch drops the warning entirely (not only from the
fill_pack_entry site, but also from an identical use in
pack-objects). If we did find the warning interesting in the
error case, we could stuff it away and reveal it to the user
when we later die() due to the broken object. But that
complexity just isn't worth it.

777c55a616 report_path_error(): move to dir.c
The expected call sequence is for the caller to use match_pathspec()
repeatedly on a set of pathspecs, accumulating the "hits" in a
separate array, and then call this function to diagnose a pathspec
that never matched anything, as that can indicate a typo from the
command line, e.g. "git commit Maekfile".

Many builtin commands use this function from builtin/ls-files.c,
which is not a very healthy arrangement.  ls-files might have been
the first command to feel the need for such a helper, but the need
is shared by everybody who uses the "match and then report" pattern.

Move it to dir.c where match_pathspec() is defined.

d95d728aba diff-lib.c: adjust position of i-t-a entries in diff
Entries added by "git add -N" are reminder for the user so that they
don't forget to add them before committing. These entries appear in
the index even though they are not real. Their presence in the index
leads to a confusing "git status" like this:

    On branch master
    Changes to be committed:
            new file:   foo

    Changes not staged for commit:
            modified:   foo

If you do a "git commit", "foo" will not be included even though
"status" reports it as "to be committed". This patch changes the
output to become

    On branch master
    Changes not staged for commit:
            new file:   foo

    no changes added to commit

The two hunks in diff-lib.c adjust "diff-index" and "diff-files" so
that i-t-a entries appear as new files in diff-files and nothing in
diff-index.

Due to this change, diff-files may start to report "new files" for the
first time. "add -u" needs to be told about this or it will die in
denial, screaming "new files can't exist! Reality is wrong." Luckily,
it's the only one among run_diff_files() callers that needs fixing.

Now in the new world order, a hierarchy in the index that contain
i-t-a paths is written out as a tree object as if these i-t-a
entries do not exist, and comparing the index with such a tree
object that would result from writing out the hierarchy will result
in no difference.  Update a test in t2203 that expected the i-t-a
entries to appear as "added to the index" in the comparison to
instead expect no output.

An earlier change eec3e7e4 (cache-tree: invalidate i-t-a paths after
generating trees, 2012-12-16) becomes an unnecessary pessimization
in the new world order---a cache-tree in the index that corresponds
to a hierarchy with i-t-a paths can now be marked as valid and
record the object name of the tree that results from writing a tree
object out of that hierarchy, as it will compare equal to that tree.

Reverting the commit is left for the future, though, as it is purely
a performance issue and no longer affects correctness.

ff4056bbc3 prune: turn on ref_paranoia flag
Prune should know about broken objects at the tips of refs,
so that we can feed them to our traversal rather than
ignoring them. It's better for us to abort the operation on
the broken object than it is to start deleting objects with
an incomplete view of the reachability namespace.

Note that for missing objects, aborting is the best we can
do. For a badly-named ref, we technically could use its sha1
as a reachability tip. However, the iteration code just
feeds us a null sha1, so there would be a reasonable amount
of code involved to pass down our wishes. It's not really
worth trying to do better, because this is a case that
should happen extremely rarely, and the message we provide:

  fatal: unable to parse object: refs/heads/bogus:name

is probably enough to point the user in the right direction.

ee0e38727f clone: initialize atexit cleanup handler earlier
If clone fails, we generally try to clean up any directories
we've created. We do this by installing an atexit handler,
so that we don't have to manually trigger cleanup. However,
since we install this after touching the filesystem, any
errors between our initial mkdir() and our atexit() call
will result in us leaving a crufty directory around.

We can fix this by moving our atexit() call earlier. It's OK
to do it before the junk_work_tree variable is set, because
remove_junk makes sure the variable is initialized. This
means we "activate" the handler by assigning to the
junk_work_tree variable, which we now bump down to just
after we call mkdir(). We probably do not want to do it
before, because a plausible reason for mkdir() to fail is
EEXIST (i.e., we are racing with another "git init"), and we
would not want to remove their work.

OTOH, this is probably not that big a deal; we will allow
cloning into an empty directory (and skip the mkdir), which
is already racy (i.e., one clone may see the other's empty
dir and start writing into it). Still, it does not hurt to
err on the side of caution here.

Note that writing into junk_work_tree and junk_git_dir after
installing the handler is also technically racy, as we call
our handler on an async signal.  Depending on the platform,
we could see a sheared write to the variables. Traditionally
we have not worried about this, and indeed we already do
this later in the function. If we want to address that, it
can come as a separate topic.

c2048f0b39 grep: fix "--quiet" overwriting current output
When grep is called with the --quiet option, the pager is initialized
despite not being used.  When the pager is "less", anything output by
previous commands and not ended with a newline is overwritten:

    $ echo -n aaa; echo bbb
    aaabbb
    $ echo -n aaa; git grep -q foo; echo bbb
    bbb

This can be worked around, for example, by making sure STDOUT is not a
TTY or more directly by setting git's pager to "cat":

    $ echo -n aaa; git grep -q foo > /dev/null; echo bbb
    aaabbb
    $ echo -n aaa; PAGER=cat git grep -q foo; echo bbb
    aaabbb

But prevent calling the pager in the first place, which would also
save an unnecessary fork().

1e8fef609e untracked cache: guard and disable on system changes
If the user enables untracked cache, then

 - move worktree to an unsupported filesystem
 - or simply upgrade OS
 - or move the whole (portable) disk from one machine to another
 - or access a shared fs from another machine

there's no guarantee that untracked cache can still function properly.
Record the worktree location and OS footprint in the cache. If it
changes, err on the safe side and disable the cache. The user can
'update-index --untracked-cache' again to make sure all conditions are
met.

This adds a new requirement that setup_git_directory* must be called
before read_cache() because we need worktree location by then, or the
cache is dropped.

This change does not cover all bases, you can fool it if you try
hard. The point is to stop accidents.

9e5972413b update-index: manually enable or disable untracked cache
Overall time saving on "git status" is about 40% in the best case
scenario, removing ..collect_untracked() as the most time consuming
function. read and refresh index operations are now at the top (which
should drop when index-helper and/or watchman support is added). More
numbers and analysis below.

webkit.git
==========

169k files. 6k dirs. Lots of test data (i.e. not touched most of the
time)

Base status
-----------

Index version 4 in split index mode and cache-tree populated. No
untracked cache. It shows how time is consumed by "git status". The
same settings are used for other repos below.

Populating status
-----------------

This is after enabling untracked cache and the cache is still empty.
We see a slight increase in .._collect_untracked() and update_index
(because new cache has to be written to $GIT_DIR/index).

----------------

After the cache is populated, wt_status_collect_untracked() drops 82%
from 0.838s to 0.144s. Overall time drops 45%. Top offenders are now
read_index() and read_index_preload().

gentoo-x86.git
==============

This repository is a strange one with a balanced, wide and shallow
worktree (about 100k files and 23k dirs) and no .gitignore in

4b06318664 branch: name detached HEAD analogous to status
"git status" carefully names a detached HEAD "at" resp. "from" a rev or
ref depending on whether the detached HEAD has moved since. "git branch"
always uses "from", which can be confusing, because a status-aware user
would interpret this as moved detached HEAD.

Make "git branch" use the same logic and wording.

fe2a18165c reflog: improve and update documentation
Revamp the "git reflog" usage documentation in the manpage and the
command help to match the current reality and improve its clarity:

* Add documentation for some options that had been left out.

* Group the subcommands and options more logically and move more
  common subcommands/options higher.

* Improve some explanations.

417305764a index-pack: reduce object_entry size to save memory
For each object in the input pack, we need one struct object_entry. On
x86-64, this struct is 64 bytes long. Although:

 - The 8 bytes for delta_depth and base_object_no are only useful when
   show_stat is set. And it's never set unless someone is debugging.

 - The three fields hdr_size, type and real_type take 4 bytes each
   even though they never use more than 4 bits.

By moving delta_depth and base_object_no out of struct object_entry
and make the other 3 fields one byte long instead of 4, we shrink 25%
of this struct.

On a 3.4M object repo (*) that's about 53MB. The saving is less
impressive compared to index-pack memory use for basic bookkeeping (**),
about 16%.

(*) linux-2.6.git already has 4M objects as of v3.19-rc7 so this is
not an unrealistic number of objects that we have to deal with.

(**)  3.4M * (sizeof(object_entry) + sizeof(delta_entry)) = 311MB

1618033401 ref_transaction_verify(): new function to check a reference's value
If NULL is passed to ref_transaction_update()'s new_sha1 parameter,
then just verify old_sha1 (under lock) without trying to change the
new value of the reference.

Use this functionality to add a new function ref_transaction_verify(),
which checks the current value of the reference under lock but doesn't
change it.

Use ref_transaction_verify() in the implementation of "git update-ref
--stdin"'s "verify" command to avoid the awkward need to "update" the
reference to its existing value.

a933c23e66 commit: avoid race when creating orphan commits
If HEAD doesn't point at anything during the initial check, then we
should make sure that it *still* doesn't point at anything when we are
ready to update the reference. Otherwise, another process might commit
while we are working (e.g., while we are waiting for the user to edit
the commit message) and we will silently overwrite it.

This fixes a failing test in t7516.
