Many messages will be marked for translation in the following
commits. This commit updates some of them to be more consistent and
reduce diff noise in those commits. Changes are
- keep the first letter of die(), error() and warning() in lowercase
- no full stop in die(), error() or warning() if it's single sentence
messages
- indentation
- some messages are turned to BUG(), or prefixed with "BUG:" and will
not be marked for i18n
- some messages are improved to give more information
- some messages are broken down by sentence to be i18n friendly
(on the same token, combine multiple warning() into one big string)
- the trailing \n is converted to printf_ln if possible, or deleted
if not redundant
- errno_errno() is used instead of explicit strerror()

The five new tests added to 't9300-fast-import.sh' in 30e215a65c
(fast-import: checkpoint: dump branches/tags/marks even if
object_count==0, 2017-09-28), all with the prefix "V:" in their test
description, run 'git fast-import' in the background and then 'kill'
it as part of a 'test_when_finished' cleanup command. When this test
script is executed with Bash, some or even all of these tests tend to
pollute the test script's stderr, and messages about terminated
processes end up on the terminal:
$ bash ./t9300-fast-import.sh
<... snip ...>
ok 179 - V: checkpoint helper does not get stuck with extra output
/<...>/test-lib-functions.sh: line 388: 28383 Terminated git fast-import $options 0<&8 1>&9
ok 180 - V: checkpoint updates refs after reset
./t9300-fast-import.sh: line 3210: 28401 Terminated git fast-import $options 0<&8 1>&9
ok 181 - V: checkpoint updates refs and marks after commit
ok 182 - V: checkpoint updates refs and marks after commit (no new objects)
./test-lib.sh: line 634: line 3250: 28485 Terminated git fast-import $options 0<&8 1>&9
ok 183 - V: checkpoint updates tags after tag
./t9300-fast-import.sh: line 3264: 28510 Terminated git fast-import $options 0<&8 1>&9
After a background child process terminates, its parent Bash process
always outputs a message like those above to stderr, even when in
non-interactive mode.
But how do some of these messages end up on the test script's stderr,
why don't we get them from all five tests, and why do they come from
different file/line locations? Well, after sending the TERM signal to
the background child process, it takes a little while until that
process receives the signal and terminates, and then it takes another
while until the parent process notices it. During this time the
parent Bash process is continuing execution, and by the time it
notices that its child terminated it might have already left
'test_eval_inner_' and its stderr is not redirected to /dev/null
anymore. That's why such a message can appear on the test script's
stderr, while other times, when the child terminates fast and/or the
parent shell is slow enough, the message ends up in /dev/null, just
like any other output of the test does. Bash always adds the file
name and line number of the code location it was about to execute when
it notices the termination of its child process as a prefix to that
message, hence the varying and sometimes totally unrelated location
prefixes in those messages (e.g. line 388 in 'test-lib-functions.sh'
is 'test_verify_prereq', and I saw such a message pointing to
'say_color' as well).
Prevent these messages from appearing on the test script's stderr by
'wait'-ing on the pid of the background 'git fast-import' process
after sending it the TERM signal. This ensures that the executing
shell's stderr is still redirected when the shell notices the
termination of its child process in the background, and that these
messages get a consistent file/line location prefix.
Note that this is not an issue when the test script is run with Bash
and '-v', because then these messages are supposed to go to the test
script's stderr anyway, and indeed all of them do; though the
sometimes seemingly random file/line prefixes could be confusing
still. Similarly, it's not an issue with Bash and '--verbose-log'
either, because then all messages go to the log file as they should.
Finally, it's not an issue with some other shells (I tried dash, ksh,
ksh93 and mksh) even without any of the verbose options, because they
don't print messages like these in non-interactive mode in the first
place.

Add test cases to cover the new X509/gpgsm support. Most of them
resemble existing ones. They just switch the format to x509 and set the
signingkey when creating signatures. Validation of signatures does not
need any configuration of git, it does need gpgsm to be configured to
trust the key(-chain).
Several of the testcases build on top of existing gpg testcases.
The commit ships a self-signed key for committer@example.com and
configures gpgsm to trust it.

This fixes a memory issue when recursing a lot, which can be reproduced as
seq 1 100000 >one
seq 1 4 100000 >two
git diff --no-index --histogram one two
Before this patch, histogram_diff would call itself recursively before
calling free_index, which would mean a lot of memory is allocated during
the recursion and only freed afterwards. By moving the memory allocation
(and its free call) into find_lcs, the memory is free'd before we recurse,
such that memory is reused in the next step of the recursion instead of
using new memory.
This addresses only the memory pressure, not the run time complexity,
that is also awful for the corner case outlined above.
Helpful in understanding the code (in addition to the sparse history of
this file), was https://stackoverflow.com/a/32367597 which reproduces

The option of --color-moved has proven to be useful as observed on the
mailing list. However when refactoring sometimes the indentation changes,
for example when partitioning a functions into smaller helper functions
the code usually mostly moved around except for a decrease in indentation.
To just review the moved code ignoring the change in indentation, a mode
to ignore spaces in the move detection as implemented in a previous patch
would be enough. However the whole move coloring as motivated in commit
2e2d5ac (diff.c: color moved lines differently, 2017-06-30), brought
up the notion of the reviewer being able to trust the move of a "block".
As there are languages such as python, which depend on proper relative
indentation for the control flow of the program, ignoring any white space
change in a block would not uphold the promises of 2e2d5ac that allows
reviewers to pay less attention to the inside of a block, as inside
the reviewer wants to assume the same program flow.
This new mode of white space ignorance will take this into account and will
only allow the same white space changes per line in each block. This patch
even allows only for the same change at the beginning of the lines.
As this is a white space mode, it is made exclusive to other white space
modes in the move detection.
This patch brings some challenges, related to the detection of blocks.
We need a wide net to catch the possible moved lines, but then need to
narrow down to check if the blocks are still intact. Consider this
example (ignoring block sizes):
- A
- B
- C
+ A
+ B
+ C
At the beginning of a block when checking if there is a counterpart
for A, we have to ignore all space changes. However at the following
lines we have to check if the indent change stayed the same.
Checking if the indentation change did stay the same, is done by computing
the indentation change by the difference in line length, and then assume
the change is only in the beginning of the longer line, the common tail
is the same. That is why the test contains lines like:
- <TAB> A
...
+ A <TAB>
...
As the first line starting a block is caught using a compare function that
ignores white spaces unlike the rest of the block, where the white space
delta is taken into account for the comparison, we also have to think about
the following situation:
- A
- B
- A
- B
+ A
+ B
+ A
+ B
When checking if the first A (both in the + and - lines) is a start of
a block, we have to check all 'A' and record all the white space deltas
such that we can find the example above to be just one block that is
indented.

We can already disable replace refs using a command line
option or environment variable, but those are awkward to
apply universally. Let's add a config option to do the same
thing.
That raises the question of why one might want to do so
universally. The answer is that replace refs violate the
immutability of objects. For instance, if you wanted to
cache the diff between commit XYZ and its parent, then in
theory that never changes; the hash XYZ represents the total
state. But replace refs violate that; pushing up a new ref
may create a completely new diff.
The obvious "if it hurts, don't do it" answer is not to
create replace refs if you're doing this kind of caching.
But for a site hosting arbitrary repositories, they may want
to allow users to share replace refs with each other, but
not actually respect them on the site (because the caching
is more important than the replace feature).
