Nguyễn Thái Ngọc Duy a73b3680c4 Add and use generic name->id mapping code for color slot parsing
Instead of hard coding the name-to-id mapping in C code, keep it in an
array and use a common function to do the parsing. This reduces code
and also allows us to list all possible color slots later.

This starts using C99 designated initializers more for convenience
(the first designated initializers have been introduced in builtin/clean.c
for some time without complaints)

Junio C Hamano 00bb99c424 Merge branch 'tb/config-default'
"git config --get" learned the "--default" option, to help the
calling script.  Building on top of the tb/config-type topic, the
"git config" learns "--type=color" type.  Taken together, you can
do things like "git config --get foo.color --default blue" and get
the ANSI color sequence for the color given to foo.color variable,
or "blue" if the variable does not exist.

  builtin/config: introduce `color` type specifier
  config.c: introduce 'git_config_color' to parse ANSI colors

Taylor Blau 6d2f9acc0f config.c: introduce 'git_config_color' to parse ANSI colors
In preparation for adding `--type=color` to the `git-config(1)` builtin,
let's introduce a color parsing utility, `git_config_color` in a similar
fashion to `git_config_<type>`.

Johannes Schindelin 8032cc4462 config: introduce an optional event stream while parsing
This extends our config parser so that it can optionally produce an event
stream via callback function, where it reports e.g. when a comment was
parsed, or a section header, etc.

This parser will be used subsequently to handle the scenarios better where
removing config entries would make sections empty, or where a new entry
could be added to an already-existing, empty section.

Haaris Mehmood 5f9674243d config: add --expiry-date
Add --expiry-date as a data-type for config files when
'git config --get' is used. This will return any relative
or fixed dates from config files as timestamps.

This is useful for scripts (e.g. gc.reflogexpire) that work
with timestamps so that '2.weeks' can be converted to a format
acceptable by those scripts/functions.

Following the convention of git_config_pathname(), move
the helper function required for this feature from
builtin/reflog.c to builtin/config.c where other similar
functions exist (e.g. for --bool or --path), and match
the order of parameters with other functions (i.e. output
pointer as first parameter).

Ben Peart 883e248b8a fsmonitor: teach git to optionally utilize a file system monitor to speed up detecting new or changed files.
When the index is read from disk, the fsmonitor index extension is used
to flag the last known potentially dirty index entries. The registered
core.fsmonitor command is called with the time the index was last
updated and returns the list of files changed since that time. This list
is used to flag any additional dirty cache entries and untracked cache

We can then use this valid state to speed up preload_index(),
ie_match_stat(), and refresh_cache_ent() as they do not need to lstat()
files to detect potential changes for those entries marked

In addition, if the untracked cache is turned on valid_cached_dir() can
skip checking directories for new or changed files as fsmonitor will
invalidate the cache only for those directories that have been
identified as having potential changes.

To keep the CE_FSMONITOR_VALID state accurate during git operations;
when git updates a cache entry to match the current state on disk,
it will now set the CE_FSMONITOR_VALID bit.

Inversely, anytime git changes a cache entry, the CE_FSMONITOR_VALID bit
is cleared and the corresponding untracked cache directory is marked

Junio C Hamano 6e96cb5286 rerere: allow approxidate in gc.rerereResolved/gc.rerereUnresolved
These two configuration variables are described in the documentation
to take an expiry period expressed in the number of days:

	    Records of conflicted merge you resolved earlier are
	    kept for this many days when 'git rerere gc' is run.
	    The default is 60 days.

	    Records of conflicted merge you have not resolved are
	    kept for this many days when 'git rerere gc' is run.
	    The default is 15 days.

There is no strong reason not to allow a more general "approxidate"
expiry specification, e.g. "5.days.ago", or "never".

Rename the config_get_expiry() helper introduced in the previous
step to git_config_get_expiry_in_days() and move it to a more
generic place, config.c, and use date.c::parse_expiry_date() to do
so.  Give it an ability to allow the caller to tell among three
cases (i.e. there is no "gc.rerereResolved" config, there is and it
is correctly parsed into the *expiry variable, and there was an
error in parsing the given value).  The current caller can work
correctly without using the return value, though.

In the future, we may find other variables that only allow an
integer that specifies "this many days" or other unit of time, and
when it happens we may need to drop "_days" suffix from the name of
the function and instead pass the "scale" value as another parameter.

But this will do for now.

Brandon Williams 3b256228a6 config: read config from a repository object
Teach the config machinery to read config information from a repository
object.  This involves storing a 'struct config_set' inside the
repository object and adding a number of functions (repo_config*) to be
able to query a repository's config.

The current config API enables lazy-loading of the config.  This means
that when 'git_config_get_int()' is called, if the_config_set hasn't
been populated yet, then it will be populated and properly initialized by
reading the necessary config files (system wide .gitconfig, user's home
.gitconfig, and the repository's config).  To maintain this paradigm,
the new API to read from a repository object's config will also perform
this lazy-initialization.

Since both APIs (git_config_get* and repo_config_get*) have the same
semantics we can migrate the default config to be stored within
'the_repository' and just have the 'git_config_get*' family of functions
redirect to the 'repo_config_get*' functions.

Brandon Williams dc8441fdb4 config: don't implicitly use gitdir or commondir
'git_config_with_options()' takes a 'config_options' struct which
contains feilds for 'git_dir' and 'commondir'.  If those feilds happen
to be NULL the config machinery falls back to querying global repository
state.  Let's change this and instead use these fields in the
'config_options' struct explicilty all the time.  Since the API is
slightly changing to require these two fields to be set if callers want
the config machinery to load the repository's config, let's change the
name to 'config_with_optison()'.  This allows the config machinery to
not implicitly rely on any global repository state.

Brandon Williams a577fb5fdc config: respect commondir
Worktrees present an interesting problem when it comes to the config.
Historically we could assume that the per-repository config lives at
'gitdir/config', but since worktrees were introduced this isn't the case
anymore.  There is currently no way to specify per-worktree
configuration, and as such the repository config is shared with all
worktrees and is located at 'commondir/config'.

Many users of the config machinery correctly set
'config_options.git_dir' with the repository's commondir, allowing the
config to be properly loaded when operating in a worktree.  But other's,
like 'read_early_config()', set 'config_options.git_dir' with the
repository's gitdir which can be incorrect when using worktrees.

To fix this issue, and to make things less ambiguous, lets add a
'commondir' field to the 'config_options' struct and have all callers
properly set both the 'git_dir' and 'commondir' fields so that the
config machinery is able to properly find the repository's config.
