a930eb03a8 rebase-interactive: rewrite edit_todo_list() to handle the initial edit
edit_todo_list() is changed to work on a todo_list, and to handle the
initial edition of the todo list (ie. making a backup of the todo
list).

It does not check for dropped commits yet, as todo_list_check() does not
take the commits that have already been processed by the rebase (ie. the
todo list is edited in the middle of a rebase session).

af1fc3adc5 rebase-interactive: append_todo_help() changes
This moves the writing of the comment "Rebase $shortrevisions onto
$shortonto ($command_count commands)" from todo_list_write_to_file() to
append_todo_help().

shortrevisions, shortonto, and command_count are passed as parameters to
append_todo_help().

During the initial edit of the todo list, shortrevisions and shortonto
are not NULL.  Therefore, if shortrevisions or shortonto is NULL, then
edit_todo would be true, otherwise it would be false.  Thus, edit_todo
is removed from the parameters of append_todo_help().

ddb81e5072 rebase-interactive: use todo_list_write_to_file() in edit_todo_list()
Just like complete_action(), edit_todo_list() used a
function (transform_todo_file()) that read the todo list from the disk
and wrote it back, resulting in useless disk accesses.

This changes edit_todo_list() to call directly todo_list_write_to_file()
instead.

6bfeb7f1b5 sequencer: refactor skip_unnecessary_picks() to work on a todo_list
This refactors skip_unnecessary_picks() to work on a todo_list.  As this
function is only called by complete_action() (and thus is not used by
rebase -p), the file-handling logic is completely dropped here.

Instead of truncating the todo list’s buffer, the items are moved to
the beginning of the list, eliminating the need to reparse the list.
This also means its buffer cannot be directly written to the disk.

rewrite_file() is then removed, as it is now unused.

94bcad7979 sequencer: change complete_action() to use the refactored functions
complete_action() used functions that read the todo-list file, made some
changes to it, and wrote it back to the disk.

The previous commits were dedicated to separate the part that deals with
the file from the actual logic of these functions.  Now that this is
done, we can call directly the "logic" functions to avoid useless file
access.

The parsing of the list has to be done by the caller.  If the buffer of
the todo list provided by the caller is empty, a `noop' command is
directly added to the todo list, without touching the buffer.

f2a04904be sequencer: refactor rearrange_squash() to work on a todo_list
This refactors rearrange_squash() to work on a todo_list to avoid
redundant reads and writes.  The function is renamed
todo_list_rearrange_squash().

The old version created a new buffer, which was directly written to the
disk.  This new version creates a new item list by just copying items
from the old item list, without creating a new buffer.  This eliminates
the need to reparse the todo list, but this also means its buffer cannot
be directly written to the disk.

As rebase -p still need to check the todo list from the disk, a new
function is introduced, rearrange_squash_in_todo_file().

complete_action() still uses rearrange_squash_in_todo_file() for now.
This will be changed in a future commit.

683153a438 sequencer: refactor sequencer_add_exec_commands() to work on a todo_list
This refactors sequencer_add_exec_commands() to work on a todo_list to
avoid redundant reads and writes to the disk.

Instead of inserting the `exec' commands between the other commands and
re-parsing the buffer at the end, they are appended to the buffer once,
and a new list of items is created.  Items from the old list are copied
across and new `exec' items are appended when necessary.  This
eliminates the need to reparse the buffer, but this also means we have
to use todo_list_write_to_disk() to write the file.

todo_list_add_exec_commands() and sequencer_add_exec_commands() are
modified to take a string list instead of a string -- one item for each
command.  This makes it easier to insert a new command to the todo list
for each command to execute.

sequencer_add_exec_commands() still reads the todo list from the disk,
as it is needed by rebase -p.

complete_action() still uses sequencer_add_exec_commands() for now.
This will be changed in a future commit.

33aa579a55 compat/bswap: add include header guards
Our compat/bswap.h lacks the usual preprocessor guards against multiple
inclusion. This usually isn't an issue since it only gets included from
git-compat-util.h, which has its own guards. But it would produce
redeclaration errors if any file included it separately.

Our hdr-check target would complain about this, except that it currently
skips items in compat/ entirely.

target complains about the missing <gcrypt.h> header file. Add the
'sha256/gcrypt.h' header file to the exception list, if the build
variable is not defined. While here, replace the 'xdiff%' filter
pattern with 'xdiff/%' (and similarly for the compat pattern) since
the original pattern inadvertently excluded the 'xdiff-interface.h'
header.

92b88eba9f Makefile: use git ls-files to list header files, if possible
In d85b0dff72 (Makefile: use `find` to determine static header
dependencies, 2014-08-25), we switched from a static list of header
files to a dynamically-generated one, asking `find` to enumerate them.

Back in those days, we did not use `$(LIB_H)` by default, and many a
`make` implementation seems smart enough not to run that `find` command
in that case, so it was deemed okay to run `find` for special targets
requiring this macro.

However, as of ebb7baf02f (Makefile: add a hdr-check target,
2018-09-19), $(LIB_H) is part of a global rule and therefore must be
expanded. Meaning: this `find` command has to be run upon every
`make` invocation. In the presence of many a worktree, this can tax the
developers' patience quite a bit.

Even in the absence of worktrees or other untracked files and
directories, the cost of I/O to generate that list of header files is
simply a lot larger than a simple `git ls-files` call.

Therefore, just like in 335339758c (Makefile: ask "ls-files" to list
source files if available, 2011-10-18), we now prefer to use `git
ls-files` to enumerate the header files to enumerating them via `find`,
falling back to the latter if the former failed (which would be the case
e.g. in a worktree that was extracted from a source .tar file rather
than from a clone of Git's sources).

This has one notable consequence: we no longer include `command-list.h`
in `LIB_H`, as it is a generated file, not a tracked one, but that is
easily worked around. Of the three sites that use `LIB_H`, two
(`LOCALIZED_C` and `CHK_HDRS`) already handle generated headers
separately. In the third, the computed-dependency fallback, we can just
add in a reference to $(GENERATED_H).

Likewise, we no longer include not-yet-tracked header files in `LIB_H`.

Given the speed improvements, these consequences seem a comparably small
price to pay.

a97d00799a remote-curl: use post_rpc() for protocol v2 also
When transmitting and receiving POSTs for protocol v0 and v1,
remote-curl uses post_rpc() (and associated functions), but when doing
the same for protocol v2, it uses a separate set of functions
(proxy_rpc() and others). Besides duplication of code, this has caused
at least one bug: the auth retry mechanism that was implemented in v0/v1
was not implemented in v2.

To fix this issue and avoid it in the future, make remote-curl also use
post_rpc() when handling protocol v2. Because line lengths are written
to the HTTP request in protocol v2 (unlike in protocol v0/v1), this
necessitates changes in post_rpc() and some of the functions it uses;
perform these changes too.

A test has been included to ensure that the code for both the unchunked
and chunked variants of the HTTP request is exercised.

Note: stateless_connect() has been updated to use the lower-level packet
reading functions instead of struct packet_reader. The low-level control
is necessary here because we cannot change the destination buffer of
struct packet_reader while it is being used; struct packet_buffer has a
peeking mechanism which relies on the destination buffer being present
in between a peek and a read.

50b206371d travis: remove the hack to build the Windows job on Azure Pipelines
Since Travis did not support Windows (and now only supports very limited
Windows jobs, too limited for our use, the test suite would time out
*all* the time), we added a hack where a Travis job would trigger an
Azure Pipeline (which back then was still called VSTS Build), wait for
it to finish (or time out), and download the log (if available).

Needless to say that it was a horrible hack, necessitated by a bad
situation.

Nowadays, however, we have Azure Pipelines support, and do not need that
hack anymore. So let's retire it.

287ab28bfa diff: reuse diff setup for --no-index case
When "--no-index" is in effect (or implied by the arguments), git-diff
jumps early to a special code path to perform that diff. This means we
miss out on some settings like enabling --ext-diff and --textconv by
default.

Let's jump to the no-index path _after_ we've done more setup on
rev.diffopt. Since some of the options don't affect us (e.g., items
related to the index), let's re-order the setup into two blocks (see the
in-code comments).

Note that we also need to stop re-initializing the diffopt struct in
diff_no_index(). This should not be necessary, as it will already have
been initialized by cmd_diff() (and there are no other callers). That in
turn lets us drop the "repository" argument from diff_no_index (which
never made much sense, since the whole point is that you don't need a
repository).

39ffebd23b README: adjust for final Azure Pipeline ID
During the six months of development of the Azure Pipelines support, the
patches went through quite a few iterations of changes, and to test
those iterations, a temporary build definition was used.

In the meantime, Azure Pipelines support made it to `master`, and we now
have a regular Azure Pipeline, installed via the common GitHub App
workflow. This new pipeline has a different name (git.git instead of
test-git.git), and a new ID (11 instead of 2).

Let's adjust the badge in our README to reflect that final shape of the
Azure Pipeline.

ae417807b0 trace2:data: pack-objects: add trace2 regions
When studying the performance of 'git push' we would like to know
how much time is spent at various parts of the command. One area
that could cause performance trouble is 'git pack-objects'.

Add trace2 regions around the three main actions taken in this
command:

1. Enumerate objects.
2. Prepare pack.
3. Write pack-file.

942b2740ff trace2:data: add trace2 regions to wt-status
Add trace2_region_enter() and trace2_region_leave() calls around the
various phases of a status scan.  This gives elapsed time for each
phase in the GIT_TR2_PERF and GIT_TR2_EVENT trace target.

Also, these Trace2 calls now use s->repo rather than the_repository.

Add platform-specific interface to log information about the current
process.

On Windows, this interface is used to indicate whether the git process

Information for other platforms is left for a future effort.

ee4512ed48 trace2: create new combined trace facility
Create a new unified tracing facility for git.  The eventual intent is to
replace the current trace_printf* and trace_performance* routines with a
unified set of git_trace2* routines.

In addition to the usual printf-style API, trace2 provides higer-level
event verbs with fixed-fields allowing structured data to be written.
This makes post-processing and analysis easier for external tools.

Trace2 defines 3 output targets.  These are set using the environment
variables "GIT_TR2", "GIT_TR2_PERF", and "GIT_TR2_EVENT".  These may be
set to "1" or to an absolute pathname (just like the current GIT_TRACE).

* GIT_TR2 is intended to be a replacement for GIT_TRACE and logs command
  summary data.

* GIT_TR2_PERF is intended as a replacement for GIT_TRACE_PERFORMANCE.
  It extends the output with columns for the command process, thread,
  repo, absolute and relative elapsed times.  It reports events for
  child process start/stop, thread start/stop, and per-thread function
  nesting.

* GIT_TR2_EVENT is a new structured format. It writes event data as a
  series of JSON records.

Calls to trace2 functions log to any of the 3 output targets enabled
without the need to call different trace_printf* or trace_performance*
routines.

c271dc28fd Delete check-racy.c
This is git-checy-racy command, added a long time ago [1] and was never
part of the default build. Naturally after some makefile changes [2],
git-check-racy was no longer recognized as a build target. Even if it
compiles to day, it will not link after the introduction of
common-main.c [3].

Racy index has not been a problem for a long time [4].  It's time to let
this code go. I briefly consider if check-racy should be part of
test-tool.  But I don't think it's worth the effort.
