When calling `git rebase -i -v`, the user wants to see some statistics
after the commits were rebased. Let's show some.
The strbuf we use to perform that task will be used for other things
in subsequent commits, hence it is declared and initialized in a wider
scope than strictly needed here.

* [PATCH v3 07/38] sequencer (rebase -i): implement the 'exec' command
From: Johannes Schindelin @ 2017-01-02 15:26 UTC (permalink / raw)
To: git
Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker, Stephan Beyer,

In-Reply-To: <cover.1483370556.git.johannes.schindelin@gmx.de>
The 'exec' command is a little special among rebase -i's commands, as it
does *not* have a SHA-1 as first parameter. Instead, everything after the
`exec` command is treated as command-line to execute.
Let's reuse the arg/arg_len fields of the todo_item structure (which hold
the oneline for pick/edit commands) to point to the command-line.

* [PATCH v3 06/38] sequencer (rebase -i): implement the 'edit' command
From: Johannes Schindelin @ 2017-01-02 15:26 UTC (permalink / raw)
To: git
Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker, Stephan Beyer,
Jeff King
In-Reply-To: <cover.1483370556.git.johannes.schindelin@gmx.de>
This patch is a straight-forward reimplementation of the `edit`
operation of the interactive rebase command.
Well, not *quite* straight-forward: when stopping, the `edit`
command wants to write the `patch` file (which is not only the
patch, but includes the commit message and author information). To
that end, this patch requires the earlier work that taught the
log-tree machinery to respect the `file` setting of
rev_info->diffopt to write to a file stream different than stdout.

* [PATCH v3 05/38] sequencer (rebase -i): implement the 'noop' command
From: Johannes Schindelin @ 2017-01-02 15:26 UTC (permalink / raw)

In-Reply-To: <cover.1483370556.git.johannes.schindelin@gmx.de>
The 'noop' command is probably the most boring of all rebase -i commands
to support in the sequencer.
Which makes it an excellent candidate for this first stab to add support
for rebase -i's commands to the sequencer.
For the moment, let's also treat empty lines and commented-out lines as
'noop'; We will refine that handling later in this patch series.
To make it easier to identify "classes" of todo_commands (such as:
determine whether a command is pick-like, i.e. handles a single commit),
let's enforce a certain order of said commands.

In-Reply-To: <cover.1483370556.git.johannes.schindelin@gmx.de>
This patch introduces a new action for the sequencer. It really does not
do a whole lot of its own right now, but lays the ground work for
patches to come. The intention, of course, is to finally make the
sequencer the work horse of the interactive rebase (the original idea
behind the "sequencer" concept).

In-Reply-To: <cover.1483370556.git.johannes.schindelin@gmx.de>
It is actually not safe to look for a commit message by looking for the
first empty line and skipping it.
The find_commit_subject() function looks more carefully, so let's use
it. Since we are interested in the entire commit message, we re-compute
the string length after verifying that the commit subject is not empty
(in which case the entire commit message would be empty, something that
should not happen but that we want to handle gracefully).

This was noticed while addressing Junio Hamano's concern that some
"else" operators were on separate lines than the preceding closing
brace.

It is the current coding style of the Git project to write
if (...) {
...
} else {
...
}
instead of putting the closing brace and the "else" keyword on separate
lines.

* [PATCH v3 00/38] Teach the sequencer to act as rebase -i's backend
From: Johannes Schindelin @ 2017-01-02 15:25 UTC (permalink / raw)
To: git
Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker, Stephan Beyer,
Jeff King
In-Reply-To: <cover.1481642927.git.johannes.schindelin@gmx.de>
This marks the count down to '3': two more patch series after this
(really tiny ones) and we have a faster rebase -i.
The idea of this patch series is to teach the sequencer to understand
all of the commands in `git-rebase-todo` scripts, to execute them and to
behave pretty much very the same as `git rebase -i --continue` when
called with the newly-introduced REPLAY_INTERACTIVE_REBASE mode.
Most of these patches should be pretty much straight-forward. When not,
I tried to make a point of describing enough background in the commit
message. Please feel free to point out where my explanations fall short.
Note that even after this patch series is applied, rebase -i is still
unaffected. It will require the next patch series which introduces the
rebase--helper that essentially implements `git rebase -i --continue` by
calling the sequencer with the appropriate options.
The final patch series will move a couple of pre- and post-processing
steps into the rebase--helper/sequencer (such as expanding/shrinking the
SHA-1s, reordering the fixup!/squash! lines, etc). This might sound like
a mere add-on, but it is essential for the speed improvements: those
stupid little processing steps really dominated the execution time in my
tests.
Apart from mostly cosmetic patches (and the occasional odd bug that I
fixed promptly), I used these patches since mid May to perform all of my
interactive rebases. In mid June, I had the idea to teach rebase -i to
run *both* scripted rebase and rebase--helper and to cross-validate the
results. This slowed down all my interactive rebases since, but helped
me catch three rather obscure bugs (e.g. that git commit --fixup unfolds
long onelines and rebase -i still finds the correct original commit).
This is all only to say that I am rather confident that the current code
does the job.
Since sending out v1, I integrated all of these patch series
into Git for Windows v2.10.0, where they have been live ever since, and
used by myself (also in a Linux VM, as Git for Windows' master branch
always builds also on Linux and passes the test suite, too).
Just to reiterate why I do all this: it speeds up the interactive rebase
substantially. Even with a not yet fully builtin rebase -i, but just the
part after the user edited the `git-rebase-todo` script.
The performance test I introduced to demonstrate this (p3404) shows a
speed-up of +380% here (i.e. roughly 5x), from ~8.8 seconds to ~1.8
seconds. This is on Windows, where the performance impact of avoiding
shell scripting is most noticable.
On MacOSX and on Linux, the speed-up is less pronounced, but still
noticable, at least if you trust Travis CI, which I abused to perform
that test for me. Check for yourself (searching for "3404.2") here:
https://travis-ci.org/git/git/builds/156295227. According to those logs,
p3404 is speeded up from ~0.45 seconds to ~0.12 seconds on Linux (read:
about 3.5x) and from ~1.7 seconds to ~0.5 seconds on MacOSX (read:
almost 4x).
Changes since v2:
- fixed a TRANSLATORS: comment
- added a comment to clarify why save_todo() does not write the current
command to git-rebase-todo
- fixed the comment for "stopped-sha" that said that a long commit name
is stored in that file, when it is in fact an abbreviated one
- consistently put the "else" keyword on the same line as the preceding
closing brace, if any (this adds two patches to the already large
patch series, sorry)
- completely revamped the update_squash_messages() function to make it
more obvious why it does not overflow its buffer, and to fix it when
using it with localised messages
- now the sequencer code uses find_commit_subject() consistently to find
the commit message (it does not use the subject's length returned by
the find_commit_subject() function, of course); this adds yet another
patch to this already large patch series, sorry.
- introduced an is_noop() function (as opposed to testing <= TODO_NOOP
manually) to make the code less magic.
- fixed two potential leaks of get_commit_buffer()'s returned buffer
- fixed leaks in the error code paths when trying to update the ref at
the end
- renamed read_author_script() into read_env_script() to reflect that
it would accept any environment setting, and made it much more
readable
- completely reworked the strategy how to suppress the output of
successful cherry-picks: instead of introducing
RUN_HIDE_STDERR_ON_SUCCESS, the code now uses pipe_command() to catch
the output itself, so that it can be shown in case of error
- replaced a spawned `diff-tree` command by code using the diff functions
directly

I thought it would make sense to convert `struct read_ref_at_cb` in
`refs.c` to use `struct object_id` at the same time, but I see that
would require the interface to `read_ref_at()` to change. I guess it's
important to pick your battles in this campaign :-)

Well, it uses the todo_command idea of a "command"... ;-)
The only thing we do with this for now is to look whether the next command
is a fixup/squash (so that the user gets to edit the commit message just
once, for example, and also to record rewritten commits properly).

Actually, no. I introduced a new function is_noop() and that is used now.

Seeing as the original intention was to do away with the
RUN_HIDE_STDERR_ON_SUCCESS flag, and that the sequencer-i branch *must*
include that functionality somehow, it is unfortunately not really
possible to do this on top of the patch series.
I say "unfortunately" because I feel pretty uncomfortable with replacing
something that has been tried and tested by something that still awaits
the test of time.
So the only possible course of action I see is to go the really long
route: incorporate the patches to use pipe_command() instead of
introducing a new RUN_* flag (which means basically munch up your patch
and Peff's and move it somewhere into the middle of the sequencer-i patch
series, which is exactly what I already did locally), cook the patches
beyond recognition in `next`, i.e. cook it really long to give it a really
good testing before moving the patches to `master`.
Ciao,
Johannes

Yeah and I don't think it's a problem in either case.
If we cannot update its timestamp, it's not a problem, as we could be
on a read-only file system, and you said in a previous iteration that
we should not even warn in this case.
If the file does not exist, it could be because it has just been
deleted for a good reason, and anyway, if it is a problem that the
shared index file has been deleted, it is better addressed when we
will actually need the shared index file to read something into from
it, rather than just to update its mtime.

So what should we do if freshen_file() returns 0 which means that the

Yeah "total" is better than "whole" here. I will use "total".

This seems better! Since I am at it, I can remove the traces of pipes

* [PATCH] connect: handle putty/plink also in GIT_SSH_COMMAND
From: Johannes Schindelin @ 2017-01-02 12:09 UTC (permalink / raw)
To: git; +Cc: Segev Finer, Junio C Hamano
From: Segev Finer <segev208@gmail.com>
Git for Windows has special support for the popular SSH client PuTTY:
when using PuTTY's non-interactive version ("plink.exe"), we use the -P
option to specify the port rather than OpenSSH's -p option. TortoiseGit
ships with its own, forked version of plink.exe, that adds support for
the -batch option, and for good measure we special-case that, too.
However, this special-casing of PuTTY only covers the case where the
user overrides the SSH command via the environment variable GIT_SSH
(which allows specifying the name of the executable), not
GIT_SSH_COMMAND (which allows specifying a full command, including
additional command-line options).
When users want to pass any additional arguments to (Tortoise-)Plink,
such as setting a private key, they are required to either use a shell
script named plink or tortoiseplink or duplicate the logic that is
already in Git for passing the correct style of command line arguments,
which can be difficult, error prone and annoying to get right.
This patch simply reuses the existing logic and expands it to cover
GIT_SSH_COMMAND, too.
Note: it may look a little heavy-handed to duplicate the entire
command-line and then split it, only to extract the name of the
executable. However, this is not a performance-critical code path, and
the code is much more readable this way.

From a cursory look a "struct cache_entry" takes at least 80 bytes
without counting the "char name[FLEX_ARRAY]" on a 32 bit machine, so I
don't think it would be a good idea to work on a repo with 20 million
paths on a 32 bit machine, but maybe theoretically it could be a
problem.
To be safe I think I will use:
return (int64_t)istate->cache_nr * max_split < (int64_t)not_shared * 100;

Currently, errors, warnings etc. are output with a fixed prefix "error: "
etc. that is not subject to l10n.
Change the call signatures of error_routine() etc. so that they receive
the prefix as first argument.

* [RFC PATCH 0/5] Localise error headers
From: Michael J Gruber @ 2017-01-02 11:14 UTC (permalink / raw)
To: git
Currently, the headers "error: ", "warning: " etc. - generated by die(),
warning() etc. - are not localized, but we feed many localized error messages
into these functions so that we produce error messages with mixed localisation.
This series introduces variants of die() etc. that use localised variants of
the headers, i.e. _("error: ") etc., and are to be fed localized messages. So,
instead of die(_("not workee")), which would produce a mixed localisation (such
as "error: geht ned"), one should use die_(_("not workee")) (resulting in
"Fehler: geht ned").
In this implementation, the gettext call for the header and the body are done
in different places (error function vs. caller) but this call pattern seems to
be the easiest variant for the caller, because the message body has to be marked
for localisation in any case, and N_() requires more letters than _(), an extra
argument to die() etc. even more than the extra "_" in the function name.
1/5 prepares the error machinery
2/5 provides new variants error_() etc.
3/5 has coccinelli rules error(_(E)) -> error_(_(E)) etc.
4/5 applies the coccinelli patches
5/5 is not to be applied to the main tree, but helps you try out the feature:
it has changes to de.po and git.pot so that e.g. "git branch" has fully localised
error messages (see the recipe in the commit message).
Michael J Gruber (5):
error/warn framework: prepare for l10n
error/warn framework: provide localized variants
error/warn framework framework: coccinelli rules
error/warn framework: localize

Is this a 32-bit system? If so, simply try to reinstall Git for Windows,
that should make it work again [*1*].
If that does not solve the problem, you will want to open a ticket at
https://github.com/git-for-windows/git/issues/new
Ciao,
Johannes
