05682ee270 Merge branch 'nd/term-columns'
The code did not propagate the terminal width to subprocesses via
COLUMNS environment variable, which it now does.  This caused
trouble to "git column" helper subprocess when "git tag --column=row"
tried to list the existing tags on a display with non-default width.

4362da078e t7005-editor: get rid of the SPACES_IN_FILENAMES prereq
The last two tests 'editor with a space' and 'core.editor with a
space' in 't7005-editor.sh' need the SPACES_IN_FILENAMES prereq to
ensure that they are only run on filesystems that allow, well, spaces
in filenames.  However, we have been putting a space in the name of
the trash directory for just over a decade now, so we wouldn't be able
to run any of our tests on such a filesystem in the first place.

This prereq is therefore unnecessary, remove it.

b5d5a567fb column: fix off-by-one default width
By default we want to fill the whole screen if possible, but we do not
want to use up _all_ terminal columns because the last character is
going hit the border, push the cursor over and wrap. Keep it at
default value zero, which will make print_columns() set the width at
term_columns() - 1.

This affects the test in t7004 because effective column width before
was 40 but now 39 so we need to compensate it by one or the output at
39 columns has a different layout.

cfb482b6c3 t5516-fetch-push: fix 'push with dry-run' test
In a while-at-it cleanup replacing a 'cd dir && <...> && cd ..' with a
subshell, commit 28391a80a9 (receive-pack: allow deletion of corrupt
refs, 2007-11-29) also moved the assignment of the $old_commit
variable to that subshell.  This variable, however, is used outside of
that subshell as a parameter of check_push_result(), to check that a
ref still points to the commit where it is supposed to.  With the
variable remaining unset outside the subshell check_push_result()
doesn't perform that check at all.

Use 'git -C <dir> cmd...', so we don't need to change directory, and
thus don't need the subshell either when setting $old_commit.

Furthermore, change check_push_result() to require at least three
parameters (the repo, the oid, and at least one ref), so it will catch
similar issues earlier should they ever arise.

87a6bb701a t5310-pack-bitmaps: make JGit tests work with GIT_TEST_SPLIT_INDEX
The two JGit tests 'we can read jgit bitmaps' and 'jgit can read our
bitmaps' in 't5310-pack-bitmaps.sh' fail when run with
GIT_TEST_SPLIT_INDEX=YesPlease.  Both tests create a clone of the test
repository to check bitmap interoperability with JGit.  With split
indexes enabled the index in the clone repositories contains the
'link' extension, which JGit doesn't support and, consequently, an
exception aborts it:

  <...>
  org.eclipse.jgit.api.errors.JGitInternalException: DIRC extension 'link' not supported by this version.
          at org.eclipse.jgit.dircache.DirCache.readFrom(DirCache.java:562)
  <...>

Since testing bitmaps doesn't need a worktree in the first place,
let's just create bare clones for the two JGit tests, so the cloned
won't have an index, and these two tests can be executed even with
split index enabled.

2e85a0c8ab http-fetch: make -a standard behaviour
This is a follow-up to a6c786fce8 (Mark http-fetch without -a as
deprecated, 2011-08-23). For more than six years, we have been warning
when `-a` is not provided, and the documentation has been saying that
`-a` will become the default.

It is a bit unclear what "default" means here. There is no such thing as
`http-fetch --no-a`. But according to my searches, no-one has been
asking on the mailing list how they should silence the warning and
prepare for overriding the flipped default. So let's assume that
everybody is happy with `-a`. They should be, since not using it may
break the repo in such a way that Git itself is unable to fix it.

Always behave as if `-a` was given. Since `-a` implies `-c` (get commit
objects) and `-t` (get trees), all three options are now unnecessary.
Document all of these as historical artefacts that have no effect.

Leave no-op code for handling these options in http-fetch.c. The
options-handling is currently rather loose. If someone tightens it, we
will not want these ignored options to accidentally turn into hard
errors.

Since `-a` was the only safe and sane usage and we have been pushing
people towards it for a long time, refrain from warning when it is used
"unnecessarily" now. Similarly, do not add anything scary-looking to the
man-page about how it will be removed in the future. We can always do so
later. (It is not like we are in desperate need of freeing up
one-letter arguments.)

63e2a0f8e9 builtin/config: introduce color type specifier
As of this commit, the canonical way to retreive an ANSI-compatible
color escape sequence from a configuration file is with the
`--get-color` action.

This is to allow Git to "fall back" on a default value for the color
should the given section not exist in the specified configuration(s).

With the addition of `--default`, this is no longer needed since:

  $ git config --default red --type=color core.section

will be have exactly as:

  $ git config --get-color core.section red

For consistency, let's introduce `--type=color` and encourage its use
with `--default` together over `--get-color` alone.

eeaa24b990 builtin/config: introduce --default
For some use cases, callers of the `git-config(1)` builtin would like to
fallback to default values when the variable asked for does not exist.
In addition, users would like to use existing type specifiers to ensure
that values are parsed correctly when they do exist in the
configuration.

For example, to fetch a value without a type specifier and fallback to
`$fallback`, the following is required:

  $ git config core.foo || echo "$fallback"

This is fine for most values, but can be tricky for difficult-to-express
`$fallback`'s, like ANSI color codes.

This motivates `--get-color`, which is a one-off exception to the normal
type specifier rules wherein a user specifies both the configuration
variable and an optional fallback. Both are formatted according to their
type specifier, which eases the burden on the user to ensure that values
are correctly formatted.

This commit (and those following it in this series) aim to eventually
replace `--get-color` with a consistent alternative. By introducing
`--default`, we allow the `--get-color` action to be promoted to a
`--type=color` type specifier, retaining the "fallback" behavior via the
`--default` flag introduced in this commit.

For example, we aim to replace:

  $ git config --get-color variable [default] [...]

with:

  $ git config --default default --type=color variable [...]

Values filled by `--default` behave exactly as if they were present in
the affected configuration file; they will be parsed by type specifiers
without the knowledge that they are not themselves present in the
configuration.

Specifically, this means that the following will work:

  $ git config --int --default 1M does.not.exist
  1048576

In subsequent commits, we will offer `--type=color`, which (in
conjunction with `--default`) will be sufficient to replace
`--get-color`.

8ab5aa4bd8 parseopt: handle malformed --expire arguments more nicely
A few commands that parse --expire=<time> command line option behave
sillily when given nonsense input.  For example

    $ git prune --no-expire
    Segmentation falut
    $ git prune --expire=npw; echo $?
    129

Both come from parse_opt_expiry_date_cb().

The former is because the function is not prepared to see arg==NULL
(for "--no-expire", it is a norm; "--expire" at the end of the
command line could be made to pass NULL, if it is told that the
argument is optional, but we don't so we do not have to worry about
that case).

The latter is because it does not check the value returned from the
underlying parse_expiry_date().

This seems to be a recent regression introduced while we attempted
to avoid spewing the entire usage message when given a correct
option but with an invalid value at 3bb0923f ("parse-options: do not
show usage upon invalid option value", 2018-03-22).  Before that, we
didn't fail silently but showed a full usage help (which arguably is
not all that better).

Also catch this error early when "git gc --prune=<expiration>" is
misspelled by doing a dummy parsing before the main body of "gc"
that is time consuming even begins.  Otherwise, we'd spend time to
pack objects and then later have "git prune" first notice the error.
Aborting "gc" in the middle that way is not harmful but is ugly and
can be avoided.

be011bbe00 fast-export: fix regression skipping some merge-commits
7199203937 (object_array: add and use `object_array_pop()`, 2017-09-23)
noted that the pattern `object = array.objects[--array.nr].item` could
be abstracted as `object = object_array_pop(&array)`.

Unfortunately, one of the conversions was horribly wrong. Between
grabbing the last object (i.e., peeking at it) and decreasing the object
count, the original code would sometimes return early. The updated code
on the other hand, will always pop the last element, then maybe do the
early return without doing anything with the object.

The end result is that merge commits where all the parents have still
not been exported will simply be dropped, meaning that they will be
completely missing from the exported data.

Re-add a commit when it is not yet time to handle it. An alternative
that was considered was to peek-then-pop. That carries some risk with it
since the peeking and popping need to act on the same object, in a
concerted fashion.

Add a test that would have caught this.

fb0dc3bac1 builtin/config.c: support --type=<type> as preferred alias for --<type>
`git config` has long allowed the ability for callers to provide a 'type
specifier', which instructs `git config` to (1) ensure that incoming
values can be interpreted as that type, and (2) that outgoing values are
canonicalized under that type.

In another series, we propose to extend this functionality with
`--type=color` and `--default` to replace `--get-color`.

However, we traditionally use `--color` to mean "colorize this output",
instead of "this value should be treated as a color".

Currently, `git config` does not support this kind of colorization, but
we should be careful to avoid squatting on this option too soon, so that
`git config` can support `--color` (in the traditional sense) in the
future, if that is desired.

In this patch, we support `--type=<int|bool|bool-or-int|...>` in
addition to `--int`, `--bool`, and etc. This allows the aforementioned
upcoming patch to support querying a color value with a default via
`--type=color --default=...`, without squandering `--color`.

We retain the historic behavior of complaining when multiple,
legacy-style `--<type>` flags are given, as well as extend this to
conflicting new-style `--type=<type>` flags. `--int --type=int` (and its
commutative pair) does not complain, but `--bool --type=int` (and its
commutative pair) does.

8b44b2be89 gpg-interface: find the last gpg signature line
A signed tag has a detached signature like this:

  object ...
  [...more header...]

  This is the tag body.

  -----BEGIN PGP SIGNATURE-----
  [opaque gpg data]
  -----END PGP SIGNATURE-----

Our parser finds the _first_ line that appears to start a
PGP signature block, meaning we may be confused by a
signature (or a signature-like line) in the actual body.
Let's keep parsing and always find the final block, which
should be the detached signature over all of the preceding
content.

e92d622536 convert: add round trip check based on 'core.checkRoundtripEncoding'
UTF supports lossless conversion round tripping and conversions between
UTF and other encodings are mostly round trip safe as Unicode aims to be
a superset of all other character encodings. However, certain encodings
(e.g. SHIFT-JIS) are known to have round trip issues [1].

Add 'core.checkRoundtripEncoding', which contains a comma separated
list of encodings, to define for what encodings Git should check the
conversion round trip if they are used in the 'working-tree-encoding'
attribute.

Set SHIFT-JIS as default value for 'core.checkRoundtripEncoding'.
