This commit unifies three separate places where whitespace checking was
performed:
- the whitespace checking previously done in builtin-apply.c is
extracted into a function in ws.c
- the equivalent logic in "git diff" is removed
- the emit_line_with_ws() function is also removed because that also
rechecks the whitespace, and its functionality is rolled into ws.c
The new function is called check_and_emit_line() and it does two things:
checks a line for whitespace errors and optionally emits it. The checking
is based on lines of content rather than patch lines (in other words, the
caller must strip the leading "+" or "-"); this was suggested by Junio on
the mailing list to allow for a future extension to "git show" to display
whitespace errors in blobs.
At the same time we teach it to report all classes of whitespace errors
found for a given line rather than reporting only the first found error.

When deciding whether or not to turn on automatic color
support, git_config_colorbool checks whether stdout is a
tty. However, because we run a pager, if stdout is not a
tty, we must check whether it is because we started the
pager. This used to be done by checking the pager_in_use
variable.
This variable was set only when the git program being run
started the pager; there was no way for an external program
running git indicate that it had already started a pager.
This patch allows a program to set GIT_PAGER_IN_USE to a
true value to indicate that even though stdout is not a tty,
it is because a pager is being used.

An earlier fix to the said commit was incomplete; it mixed up the
meaning of the flag parameter passed to the internal fmt_ident()
function, so this corrects it.
git_author_info() and git_committer_info() can be told to issue a
warning when no usable user information is found, and optionally can be
told to error out. Operations that actually use the information to
record a new commit or a tag will still error out, but the caller to
leave reflog record will just silently use bogus user information.
Not warning on misconfigured user information while writing a reflog
entry is somewhat debatable, but it is probably nicer to the users to
silently let it pass, because the only information you are losing is who
checked out the branch.
* git_author_info() and git_committer_info() used to take 1 (positive
int) to error out with a warning on misconfiguration; this is now
signalled with a symbolic constant IDENT_ERROR_ON_NO_NAME.
* These functions used to take -1 (negative int) to warn but continue;
this is now signalled with a symbolic constant IDENT_WARN_ON_NO_NAME.
* fmt_ident() function implements the above error reporting behaviour
common to git_author_info() and git_committer_info(). A symbolic
constant IDENT_NO_DATE can be or'ed in to the flag parameter to make
it return only the "Name <email@address.xz>".
* fmt_name() is a thin wrapper around fmt_ident() that always passes
IDENT_ERROR_ON_NO_NAME and IDENT_NO_DATE.

The `core.whitespace` configuration variable allows you to define what
`diff` and `apply` should consider whitespace errors for all paths in
the project (See gitlink:git-config[1]). This attribute gives you finer
control per path.
For example, if you have these in the .gitattributes:
frotz whitespace
nitfol -whitespace
xyzzy whitespace=-trailing
all types of whitespace problems known to git are noticed in path 'frotz'
(i.e. diff shows them in diff.whitespace color, and apply warns about
them), no whitespace problem is noticed in path 'nitfol', and the
default types of whitespace problems except "trailing whitespace" are
noticed for path 'xyzzy'. A project with mixed Python and C might want
to have:
*.c whitespace
*.py whitespace=-indent-with-non-tab
in its toplevel .gitattributes file.

This exports three helper functions from ls-files.
* pathspec_match() checks if a given path matches a set of pathspecs
and optionally records which pathspec was used. This function used
to be called "match()" but renamed to be a bit less vague.
* report_path_error() takes a set of pathspecs and the record
pathspec_match() above leaves, and gives error message. This
was split out of the main function of ls-files.
* overlay_tree_on_cache() takes a tree-ish (typically "HEAD")
and overlays it on the current in-core index. By iterating
over the resulting index, the caller can find out the paths
in either the index or the HEAD. This function used to be
called "overlay_tree()" but renamed to be a bit more
descriptive.

The old rules used by fetch were coded as a series of ifs. The old
rules are:
1) match full refname if it starts with "refs/" or matches "HEAD"
2) verify that full refname starts with "refs/"
3) match abbreviated name in "refs/" if it starts with "heads/",
"tags/", or "remotes/".
4) match abbreviated name in "refs/heads/"
This is replaced by the new rules
a) match full refname
b) match abbreviated name prefixed with "refs/"
c) match abbreviated name prefixed with "refs/heads/"
The details of the new rules are different from the old rules. We no
longer verify that the full refname starts with "refs/". The new rule
(a) matches any full string. The old rules (1) and (2) were stricter.
Now, the caller is responsible for using sensible full refnames. This
should be the case for the current code. The new rule (b) is less
strict than old rule (3). The new rule accepts abbreviated names that
start with a non-standard prefix below "refs/".
Despite this modifications the new rules should handle all cases as
expected. Two tests are added to verify that fetch does not resolve
short tags or HEAD in remotes.
We may even think about loosening the rules a bit more and unify them
with the rev-parse rules. This would be done by replacing
ref_ref_fetch_rules with ref_ref_parse_rules. Note, the two new test
would break.

We use at least two rulesets for matching abbreviated refnames with
full refnames (starting with 'refs/'). git-rev-parse and git-fetch
use slightly different rules.
This commit introduces a new function refname_match
(const char *abbrev_name, const char *full_name, const char **rules).
abbrev_name is expanded using the rules and matched against full_name.
If a match is found the function returns true. rules is a NULL-terminate
list of format patterns with "%.*s", for example:
const char *ref_rev_parse_rules[] = {
"%.*s",
"refs/%.*s",
"refs/tags/%.*s",
"refs/heads/%.*s",
"refs/remotes/%.*s",
"refs/remotes/%.*s/HEAD",
NULL
};
Asterisks are included in the format strings because this is the form
required in sha1_name.c. Sharing the list with the functions there is
a good idea to avoid duplicating the rules. Hopefully this
facilitates unified matching rules in the future.
This commit makes the rules used by rev-parse for resolving refs to
sha1s available for string comparison. Before this change, the rules
were buried in get_sha1*() and dwim_ref().
A follow-up commit will refactor the rules used by fetch.
refname_match() will be used for matching refspecs in git-send-pack.
Thanks to Daniel Barkalow <barkalow@iabervon.org> for pointing
out that ref_matches_abbrev in remote.c solves a similar problem

Previously, we set all ref pushes to 'OK', and then marked
them as errors if the remote reported so. This has the
problem that if the remote dies or fails to report a ref, we
just assume it was OK.
Instead, we use a new non-OK state to indicate that we are
expecting status (if the remote doesn't support the
report-status feature, we fall back on the old behavior).
Thus we can flag refs for which we expected a status, but
got none (conversely, we now also print a warning for refs
for which we get a status, but weren't expecting one).
This also allows us to simplify the receive_status exit
code, since each ref is individually marked with failure
until we get a success response. We can just print the usual
status table, so the user still gets a sense of what we were
trying to do when the failure happened.

This lets us show remote errors (e.g., a denied hook) along
with the usual push output.
There is a slightly clever optimization in receive_status
that bears explanation. We need to correlate the returned
status and our ref objects, which naively could be an O(m*n)
operation. However, since the current implementation of
receive-pack returns the errors to us in the same order that
we sent them, we optimistically look for the next ref to be
looked up to come after the last one we have found. So it
should be an O(m+n) merge if the receive-pack behavior
holds, but we fall back to a correct but slower behavior if
it should change.

Instead of keeping the 'ret' variable, we instead have a
status flag for each ref that tracks what happened to it.
We then print the ref status after all of the refs have
been examined.
This paves the way for three improvements:
- updating tracking refs only for non-error refs
- incorporating remote rejection into the printed status
- printing errors in a different order than we processed
(e.g., consolidating non-ff errors near the end with
a special message)

In a subsequent patch the path to the system-wide config file will be
computed. This is a preparation for that change. It turns all accesses
of ETC_GITCONFIG into function calls. There is no change in behavior.
As a consequence, config.c is the only file that needs the definition of
ETC_GITCONFIG. Hence, -DETC_GITCONFIG is removed from the CFLAGS and a
special build rule for config.c is introduced. As a side-effect, changing
the defintion of ETC_GITCONFIG (e.g. in config.mak) does not trigger a

There are inconsistencies in the way commands currently handle
the core.excludesfile configuration variable. The problem is
the variable is too new to be noticed by anything other than
git-add and git-status.
* git-ls-files does not notice any of the "ignore" files by
default, as it predates the standardized set of ignore files.
The calling scripts established the convention to use
.git/info/exclude, .gitignore, and later core.excludesfile.
* git-add and git-status know about it because they call
add_excludes_from_file() directly with their own notion of
which standard set of ignore files to use. This is just a
stupid duplication of code that need to be updated every time
the definition of the standard set of ignore files is
changed.
* git-read-tree takes --exclude-per-directory=<gitignore>,
not because the flexibility was needed. Again, this was
because the option predates the standardization of the ignore
files.
* git-merge-recursive uses hardcoded per-directory .gitignore
and nothing else. git-clean (scripted version) does not
honor core.* because its call to underlying ls-files does not
know about it. git-clean in C (parked in 'pu') doesn't either.
We probably could change git-ls-files to use the standard set
when no excludes are specified on the command line and ignore
processing was asked, or something like that, but that will be a
change in semantics and might break people's scripts in a subtle
way. I am somewhat reluctant to make such a change.
On the other hand, I think it makes perfect sense to fix
git-read-tree, git-merge-recursive and git-clean to follow the
same rule as other commands. I do not think of a valid use case
to give an exclude-per-directory that is nonstandard to
read-tree command, outside a "negative" test in the t1004 test
script.
This patch is the first step to untangle this mess.
The next step would be to teach read-tree, merge-recursive and
clean (in C) to use setup_standard_excludes().

This introduces a new whitespace error type, "indent-with-non-tab".
The error is about starting a line with 8 or more SP, instead of
indenting it with a HT.
This is not enabled by default, as some projects employ an
indenting policy to use only SPs and no HTs.
The kernel folks and git contributors may want to enable this
detection with:
[core]
whitespace = indent-with-non-tab
Signed-off-by: Junio C Hamano <gitster@pobox.com>
This introduces core.whitespace configuration variable that lets
you specify the definition of "whitespace error".
Currently there are two kinds of whitespace errors defined:
* trailing-space: trailing whitespaces at the end of the line.
* space-before-tab: a SP appears immediately before HT in the
indent part of the line.
You can specify the desired types of errors to be detected by
listing their names (unique abbreviations are accepted)
separated by comma. By default, these two errors are always
detected, as that is the traditional behaviour. You can disable
detection of a particular type of error by prefixing a '-' in
front of the name of the error, like this:
[core]
whitespace = -trailing-space
This patch teaches the code to output colored diff with
DIFF_WHITESPACE color to highlight the detected whitespace
errors to honor the new configuration.
