Switch from gcc-4.8 to gcc-8. Newer compilers come with more warning
checks (usually in -Wextra). Since -Wextra is enabled in developer
mode (which is also enabled in travis), this lets travis report more
warnings before other people do it.

On linux 64-bit architecture, pahole finds that there's a 4 bytes
padding after 'index'. Moving it to the end reduces this struct's size
from 72 to 64 bytes (because of another 4 bytes padding after
graph_pos). On linux 32-bit, the struct size remains 52 bytes like
before.

"git update-ref A B" is supposed to ensure that ref A does not yet
exist when B is a NULL OID, but this check was not done correctly
for pseudo-refs outside refs/ hierarchy, e.g. MERGE_HEAD.
* ma/create-pseudoref-with-null-old-oid:
refs: handle zero oid for pseudorefs
t1400: add tests around adding/deleting pseudorefs
refs.c: refer to "object ID", not "sha1", in error messages

According to the documentation, it is possible to "specify 40 '0' or an
empty string as <oldvalue> to make sure that the ref you are creating
does not exist." But in the code for pseudorefs, we do not implement
this, as demonstrated by the failing tests added in the previous commit.
If we fail to read the old ref, we immediately die. But a failure to
read would actually be a good thing if we have been given the zero oid.
With the zero oid, allow -- and even require -- the ref-reading to fail.
This implements the "make sure that the ref ... does not exist" part of
the documentation and fixes both failing tests from the previous commit.
Since we have a `strbuf err` for collecting errors, let's use it and
signal an error to the caller instead of dying hard.

I have not been able to find any tests around adding pseudorefs using
`git update-ref`. Add some as outlined in this table (original design by
Michael Haggerty; modified and extended by me):
Pre-update value | ref-update old OID | Expected result
-------------------|----------------------|----------------
missing | value | reject
missing | none given | accept
set | none given | accept
set | correct value | accept
set | wrong value | reject
missing | zero | accept *
set | zero | reject *
The tests marked with a * currently fail, despite git-update-ref(1)
claiming that it is possible to "specify 40 '0' or an empty string as
<oldvalue> to make sure that the ref you are creating does not exist."
These failing tests will be fixed in the next commit.
It is only natural to test deletion as well. Test deletion without an
old OID, with a correct one and with an incorrect one.

We have two error messages that complain about the "sha1". Because we
are about to touch one of these sites and add some tests, let's first
modernize the messages to say "object ID" instead.
While at it, make the second one use `error()` instead of `warning()`.
After printing the message, we do not continue, but actually drop the
lock and return -1 without deleting the pseudoref.

Commit 941ba8db57 (Eliminate recursion in setting/clearing
marks in commit list, 2012-01-14) used a clever double-loop
to avoid allocations for single-parent chains of history.
However, it did so only when following parents of parents
(which was an uncommon case), and _always_ incurred at least
one allocation to populate the list of pending parents in
the first place.
We can turn this into zero-allocation in the common case by
iterating directly over the initial parent list, and then
following up on any pending items we might have discovered.

The mark_parents_uninteresting() function uses two loops:
an outer one to process our queue of pending parents, and an
inner one to process first-parent chains. This is a clever
optimization from 941ba8db57 (Eliminate recursion in
setting/clearing marks in commit list, 2012-01-14) to limit
the number of linked-list allocations when following
single-parent chains.
Unfortunately, this makes the result a little hard to read.
Let's replace the list with a stack. Then we don't have to
worry about doing this double-loop optimization, as we'll
just reuse the top element of the stack as we pop/push.

We allow UNINTERESTING objects in a traversal to be
unavailable. As part of this, mark_parents_uninteresting()
checks whether we have a particular uninteresting parent; if
not, we will mark it as "parsed" so that later code skips
it.
This code is redundant and even a little bit harmful, so
let's drop it.
It's redundant because when our parse_object() call in
add_parents_to_list() fails, we already quietly skip
UNINTERESTING parents. This redundancy is a historical
artifact. The mark_parents_uninteresting() protection is
from 454fbbcde3 (git-rev-list: allow missing objects when
the parent is marked UNINTERESTING, 2005-07-10). Much later,
aeeae1b771 (revision traversal: allow UNINTERESTING objects
to be missing, 2009-01-27) covered more cases by making the
actual parse more gentle.
As an aside, even if this weren't redundant, it would be
insufficient. The gentle parsing handles both missing and
corrupted objects, whereas the has_object_file() check
we're getting rid of covers only missing ones.
And the code we're dropping is harmful for two reasons:
1. We spend extra time on the object lookup, even though
we don't actually need the information at this point
(and will just repeat that lookup later when we parse
for the common case that we _do_ have the object).
2. It "lies" about the commit by setting the parsed flag,
even though we didn't load any useful data into the
struct. This shouldn't matter for the UNINTERESTING
case, but we may later clear our flags and do another
traversal in the same process. While pretty unlikely,
it's possible that we could then look at the same
commit without the UNINTERESTING flag, in which case
we'd produce the wrong result (we'd think it's a commit
with no parents, when in fact we should probably die
due to the missing object).

It's generally acceptable for UNINTERESTING objects in a
traversal to be unavailable (e.g., see aeeae1b771). When
marking trees UNINTERESTING, we access the object database
twice: once to check if the object is missing (and return
quietly if it is), and then again to actually parse it.
We can instead just try to parse; if that fails, we can then
return quietly. That halves the effort we spend on locating
the object.
Note that this isn't _exactly_ the same as the original
behavior, as the parse failure could be due to other
problems than a missing object: it could be corrupted, in
which case the original code would have died. But the new
behavior is arguably better, as it covers the object being
unavailable for any reason. We'll also still issue a warning
to stderr in such a case.

"git status" learned to honor a new status.renames configuration to

After performing a merge that has conflicts git status will, by default,
attempt to detect renames which causes many objects to be examined. In a
virtualized repo, those objects do not exist locally so the rename logic
triggers them to be fetched from the server. This results in the status call
taking hours to complete on very large repos vs seconds with this patch.
Add a new config status.renames setting to enable turning off rename
detection during status and commit. This setting will default to the value
of diff.renames.
Add a new config status.renamelimit setting to to enable bounding the time
spent finding out inexact renames during status and commit. This setting
will default to the value of diff.renamelimit.
Add --no-renames command line option to status that enables overriding the
config setting from the command line. Add --find-renames[=<n>] command line
option to status that enables detecting renames and optionally setting the
similarity index.

These were not caught by the previous commit, as they did not match the
regular expression.
While at it, remove the localization from one instance: we never want
BUG() messages to be translated, as they target Git developers, not the
end user (hence it would be quite unhelpful to not only burden the
translators, but then even end up with a bug report in a language that
no core Git contributor understands).

In d8193743e08 (usage.c: add BUG() function, 2017-05-12), a new macro
was introduced to use for reporting bugs instead of die(). It was then
subsequently used to convert one single caller in 588a538ae55
(setup_git_env: convert die("BUG") to BUG(), 2017-05-12).
The cover letter of the patch series containing this patch
(cf 20170513032414.mfrwabt4hovujde2@sigill.intra.peff.net) is not
terribly clear why only one call site was converted, or what the plan
is for other, similar calls to die() to report bugs.
Let's just convert all remaining ones in one fell swoop.
This trick was performed by this invocation:
sed -i 's/die("BUG: /BUG("/g' $(git grep -l 'die("BUG' \*.c)

The slightly misleading name die_bug() of the function intended to
report a bug is actually called always, and only reports a bug if the
passed-in parameter `err` is non-zero.
It uses die_errno() to report the bug, to helpfully include the error
message corresponding to `err`.
However, as these messages indicate bugs, we really should use BUG().
And as BUG() is a macro to be able to report the exact file and line
number, we need to convert die_bug() to a macro instead of only
replacing the die_errno() by a call to BUG().
While at it, use a name more indicative of the purpose: CHECK_BUG().

When we call BUG(), we signal via SIGABRT that something bad happened,
dumping cores if so configured. In some setups these coredumps are
redirected to some central place such as /proc/sys/kernel/core_pattern,
which is a good thing.
However, when we try to verify in our test suite that bugs are caught in
certain code paths, we do *not* want to clutter such a central place
with unnecessary coredumps.
So let's special-case the test helpers (which we use to verify such code
paths) so that the BUG() calls will *not* call abort() but exit with a
special-purpose exit code instead.

The compiler is correct, and the error message speaks for itself. There
is no need for any undefined operation -- just cast mark to void * or
uint32_t after an intermediate cast to uintptr_t. That encodes the
integer value into a pointer and later decodes it as intended.

the_repository is special. One of the special things about it is that
it does not allocate a new index_state object like submodules but
points to the global the_index variable instead. As a global variable,
the_index cannot be free()'d.
Add an exception for this in repo_clear(). In the future perhaps we
would be able to allocate the_repository's index on heap too. Then we
can revert this.
the_repository->index remains pointed to a clean the_index even after
repo_clear() so that it could still be used next time (e.g. in a crazy
use case where a dev switches repo in the same process).

Placing `struct lock_file`s on the stack used to be a bad idea, because
the temp- and lockfile-machinery would keep a pointer into the struct.
But after 076aa2cbd (tempfile: auto-allocate tempfiles on heap,
2017-09-05), we can safely have lockfiles on the stack. (This applies
even if a user returns early, leaving a locked lock behind.)
Each of these `struct lock_file`s is used from within a single function.
Move them into the respective functions to make the scope clearer and
drop the staticness.
For good measure, I have inspected these sites and come to believe that
they always release the lock, with the possible exception of bailing out
using `die()` or `exit()` or by returning from a `cmd_foo()`.
As pointed out by Jeff King, it would be bad if someone held on to a
`struct lock_file *` for some reason. After some grepping, I agree with
his findings: no-one appears to be doing that.
After this commit, the remaining occurrences of "static struct
lock_file" are locks that are used from within different functions. That
is, they need to remain static. (Short of more intrusive changes like
passing around pointers to non-static locks.)

These `struct lock_file`s are local to their respective functions and we
can drop their staticness.
For good measure, I have inspected these sites and come to believe that
they always release the lock, with the possible exception of bailing out
using `die()` or `exit()` or by returning from a `cmd_foo()`.
As pointed out by Jeff King, it would be bad if someone held on to a
`struct lock_file *` for some reason. After some grepping, I agree with
his findings: no-one appears to be doing that.

After taking the lock we check whether we got it and die otherwise. But
since we take the lock using `LOCK_DIE_ON_ERROR`, we would already have
died.
Considering the choice between dropping the dead code and dropping the
flag, let's go for option number three: Drop the flag, write an error
instead of dying, then return -1. This function already returns -1 for
another error, so the caller (or rather, its callers) should be able to
handle this. There is some inconsistency around how we handle errors in
this function and elsewhere in this file, but let's take this small step
towards gentle error-reporting now and leave the rest for another time.
While at it, make the lock non-static and reduce its scope. (Placing
`struct lock_file`s on the stack used to be a bad idea, because the
temp- and lockfile-machinery would keep a pointer into the struct. But
after 076aa2cbd (tempfile: auto-allocate tempfiles on heap, 2017-09-05),
we can safely have lockfiles on the stack.)

If we could not take the lock, we add an error to the `strbuf err` and
return. However, this code is dead. The reason is that we take the lock
using `LOCK_DIE_ON_ERROR`. Drop the flag to allow our more gentle
error-handling to actually kick in.
We could instead just drop the dead code and die here. But everything is
prepared for gently propagating the error, so let's do that instead.
There is similar dead code in `delete_pseudoref()`, but let's save that
for the next patch.
While at it, make the lock non-static. (Placing `struct lock_file`s on

Die in case writing the index fails, so that the caller can notice
(instead of, say, being impressed by how performant the writing is).
While at it, note that after opening a lock with `LOCK_DIE_ON_ERROR`, we
do not need to worry about whether we succeeded. Also, we can move the
`struct lock_file` into the function and drop the staticness. (Placing

The test script 't6050-replace.sh' starts off with redirecting the
whole test script's stdin from /dev/null. This redirection has been
there since the test script was introduced in a3e8267225
(replace_object: add a test case, 2009-01-23), but the commit message
doesn't explain why it was deemed necessary. AFAICT, it has never
been necessary, and t6050 runs just fine and succeeds even without it,
not only the current version but past versions as well.
Besides being unnecessary, this redirection is also harmful, as it
prevents the test helper functions 'test_pause' and 'debug' from
working properly in t6050, because we can't enter any commands to the
shell and the debugger, respectively.
So let's remove that redirection.

In the context of the new --rebase-merges mode, which was designed
specifically to allow for changing the existing branch topology
liberally, a user may want to extract commits into a completely fresh
branch that starts with a newly-created root commit.
This is now possible by inserting the command `reset [new root]` before
`pick`ing the commit that wants to become a root commit. Example:
reset [new root]
pick 012345 a commit that is about to become a root commit
pick 234567 this commit will have the previous one as parent
This does not conflict with other uses of the `reset` command because
`[new root]` is not (part of) a valid ref name: both the opening bracket
as well as the space are illegal in ref names.

In this developer's earlier attempt to accelerate interactive rebases by
converting large parts from Unix shell script into portable, performant
C, the --root handling was specifically excluded (to simplify the task a
little bit; it still took over a year to get that reduced set of patches
into Git proper).
This patch ties up that loose end: now only --preserve-merges uses the
slow Unix shell script implementation to perform the interactive rebase.
As the rebase--helper reports progress to stderr (unlike the scripted
interactive rebase, which reports it to stdout, of all places), we have
to adjust a couple of tests that did not expect that for `git rebase -i
--root`.
This patch fixes -- at long last! -- the really old bug reported in
6a6bc5bdc4d (add tests for rebasing root, 2013-06-06) that rebasing with
--root *always* rewrote the root commit, even if there were no changes.
The bug still persists in --preserve-merges mode, of course, but that
mode will be deprecated as soon as the new --rebase-merges mode
stabilizes, anyway.

When an interactive rebase wants to recreate a root commit, it
- first creates a new, empty root commit,
- checks it out,
- converts the next `pick` command so that it amends the empty root
commit
Introduce support in the sequencer to handle such an empty root commit,
by looking for the file <GIT_DIR>/rebase-merge/squash-onto; if it exists
and contains a commit name, the sequencer will compare the HEAD to said
root commit, and if identical, a new root commit will be created.
While converting scripted code into proper, portable C, we also do away
with the old "amend with an empty commit message, then cherry-pick
without committing, then amend again" dance and replace it with code
that uses the internal API properly to do exactly what we want: create a
new root commit.
To keep the implementation simple, we always spawn `git commit` to create
new root commits.
