Optimize directory listing with pathspec limiter.
The way things are set up, you can now pass a "pathspec" to the
"read_directory()" function. If you pass NULL, it acts exactly
like it used to do (read everything). If you pass a non-NULL
pointer, it will simplify it into a "these are the prefixes
without any special characters", and stop any readdir() early if
the path in question doesn't match any of the prefixes.
NOTE! This does *not* obviate the need for the caller to do the *exact*
pathspec match later. It's a first-level filter on "read_directory()", but
it does not do the full pathspec thing. Maybe it should. But in the
meantime, builtin-add.c really does need to do first
read_directory(dir, .., pathspec);
if (pathspec)
prune_directory(dir, pathspec, baselen);
ie the "prune_directory()" part will do the *exact* pathspec pruning,
while the "read_directory()" will use the pathspec just to do some quick
high-level pruning of the directories it will recurse into.

dir.c: git-status --ignored: don't scan the work tree three times
'git-status --ignored' recursively scans directories up to three times:
1. To collect untracked files.
2. To collect ignored files.
3. When collecting ignored files, to check that an untracked directory
that potentially contains ignored files doesn't also contain untracked
files (i.e. isn't already listed as untracked).
Let's get rid of case 3 first.
Currently, read_directory_recursive returns a boolean whether a directory
contains the requested files or not (actually, it returns the number of
files, but no caller actually needs that), and DIR_SHOW_IGNORED specifies
what we're looking for.
To be able to test for both untracked and ignored files in a single scan,
we need to return a bit more info, and the result must be independent of
the DIR_SHOW_IGNORED flag.
Reuse the path_treatment enum as return value of read_directory_recursive.
Split path_handled in two separate values path_excluded and path_untracked
that don't change their meaning with the DIR_SHOW_IGNORED flag. We don't
need an extra value path_untracked_and_excluded, as directories with both
untracked and ignored files should be listed as untracked.
Rename path_ignored to path_none for clarity (i.e. "don't treat that path"
in contrast to "the path is ignored and should be treated according to
DIR_SHOW_IGNORED").
Replace enum directory_treatment with path_treatment. That's just another
enum with the same meaning, no need to translate back and forth.
In treat_directory, get rid of the extra read_directory_recursive call and
all the DIR_SHOW_IGNORED-specific code.
In read_directory_recursive, decide whether to dir_add_name path_excluded
or path_untracked paths based on the DIR_SHOW_IGNORED flag.
The return value of read_directory_recursive is the maximum path_treatment
of all files and sub-directories. In the check_only case, abort when we've
reached the most significant value (path_untracked).

dir.c::match_basename(): pay attention to the length of string parameters
The function takes two counted strings (<basename, basenamelen> and
<pattern, patternlen>) as parameters, together with prefix (the
length of the prefix in pattern that is to be matched literally
without globbing against the basename) and EXC_* flags that tells it
how to match the pattern against the basename.
However, it did not pay attention to the length of these counted
strings. Update them to do the following:
* When the entire pattern is to be matched literally, the pattern
matches the basename only when the lengths of them are the same,
and they match up to that length.
* When the pattern is "*" followed by a string to be matched
literally, make sure that the basenamelen is equal or longer than
the "literal" part of the pattern, and the tail of the basename
string matches that literal part.
* Otherwise, use the new fnmatch_icase_mem helper to make
sure we only lookmake sure we use only look at the
counted part of the strings. Because these counted strings are
full strings most of the time, we check for termination
to avoid unnecessary allocation.

|
|
|
|
* it's ok for #2 to match extra files. Those extras will be
|
|
|
|
* trimmed at #3.
|
|
|
|
*
|

|
* Suppose the pathspec is 'foo' and '../bar' running from
|
|
|
|
* subdir 'xyz'. The common prefix at #1 will be empty, thanks
|
|
|
|
* to "../". We may have xyz/foo _and_ XYZ/foo after #2. The
|
|
|
|
* user does not want XYZ/foo, only the "foo" part should be
|
|
|
|
* case-insensitive. We need to filter out XYZ/foo here. In
|
|
|
|
* other words, we do not trust the caller on comparing the
|
|
|
|
* prefix part when :(icase) is involved. We do exact
|
|
|
|
* comparison ourselves.
|
|
|
|
*
|
|
|
|
* Normally the caller (common_prefix_len() in fact) does
|
|
|
|
* _exact_ matching on name[-prefix+1..-1] and we do not need
|
|
|
|
* to check that part. Be defensive and check it anyway, in
|
|
|
|
* case common_prefix_len is changed, or a new caller is
|
|
|
|
* introduced that does not use common_prefix_len.
|
|
|
|
*
|
|
|
|
* If the penalty turns out too high when prefix is really
|
|
|
|
* long, maybe change it to
|

dir.c: unify is_excluded and is_path_excluded APIs
The is_excluded and is_path_excluded APIs are very similar, except for a
few noteworthy differences:
is_excluded doesn't handle ignored directories, results for paths within
ignored directories are incorrect. This is probably based on the premise
that recursive directory scans should stop at ignored directories, which
is no longer true (in certain cases, read_directory_recursive currently
calls is_excluded *and* is_path_excluded to get correct ignored state).
is_excluded caches parsed .gitignore files of the last directory in struct
dir_struct. If the directory changes, it finds a common parent directory
and is very careful to drop only as much state as necessary. On the other
hand, is_excluded will also read and parse .gitignore files in already
ignored directories, which are completely irrelevant.
is_path_excluded correctly handles ignored directories by checking if any
component in the path is excluded. As it uses is_excluded internally, this
unfortunately forces is_excluded to drop and re-read all .gitignore files,
as there is no common parent directory for the root dir.
is_path_excluded tracks state in a separate struct path_exclude_check,
which is essentially a wrapper of dir_struct with two more fields. However,
as is_path_excluded also modifies dir_struct, it is not possible to e.g.
use multiple path_exclude_check structures with the same dir_struct in
parallel. The additional structure just unnecessarily complicates the API.
Teach is_excluded / prep_exclude about ignored directories: whenever
entering a new directory, first check if the entire directory is excluded.
Remember the excluded state in dir_struct. Don't traverse into already
ignored directories (i.e. don't read irrelevant .gitignore files).
Directories could also be excluded by exclude patterns specified on the
command line or .git/info/exclude, so we cannot simply skip prep_exclude
entirely if there's no .gitignore file name (dir_struct.exclude_per_dir).
Move this check to just before actually reading the file.
is_path_excluded is now equivalent to is_excluded, so we can simply
redirect to it (the public API is cleaned up in the next patch).
The performance impact of the additional ignored check per directory is
hardly noticeable when reading directories recursively (e.g. 'git status').
However, performance of git commands using the is_path_excluded API (e.g.
'git ls-files --cached --ignored --exclude-standard') is greatly improved
as this no longer re-reads .gitignore files on each call.

runs on a Debian Linux on SSD, core.preloadIndex=true):

dir.c: unify is_excluded and is_path_excluded APIs
The is_excluded and is_path_excluded APIs are very similar, except for a
few noteworthy differences:
is_excluded doesn't handle ignored directories, results for paths within
ignored directories are incorrect. This is probably based on the premise
that recursive directory scans should stop at ignored directories, which
is no longer true (in certain cases, read_directory_recursive currently
calls is_excluded *and* is_path_excluded to get correct ignored state).
is_excluded caches parsed .gitignore files of the last directory in struct
dir_struct. If the directory changes, it finds a common parent directory
and is very careful to drop only as much state as necessary. On the other
hand, is_excluded will also read and parse .gitignore files in already
ignored directories, which are completely irrelevant.
is_path_excluded correctly handles ignored directories by checking if any
component in the path is excluded. As it uses is_excluded internally, this
unfortunately forces is_excluded to drop and re-read all .gitignore files,
as there is no common parent directory for the root dir.
is_path_excluded tracks state in a separate struct path_exclude_check,
which is essentially a wrapper of dir_struct with two more fields. However,
as is_path_excluded also modifies dir_struct, it is not possible to e.g.
use multiple path_exclude_check structures with the same dir_struct in
parallel. The additional structure just unnecessarily complicates the API.
Teach is_excluded / prep_exclude about ignored directories: whenever
entering a new directory, first check if the entire directory is excluded.
Remember the excluded state in dir_struct. Don't traverse into already
ignored directories (i.e. don't read irrelevant .gitignore files).
Directories could also be excluded by exclude patterns specified on the
command line or .git/info/exclude, so we cannot simply skip prep_exclude
entirely if there's no .gitignore file name (dir_struct.exclude_per_dir).
Move this check to just before actually reading the file.
is_path_excluded is now equivalent to is_excluded, so we can simply
redirect to it (the public API is cleaned up in the next patch).
The performance impact of the additional ignored check per directory is
hardly noticeable when reading directories recursively (e.g. 'git status').
However, performance of git commands using the is_path_excluded API (e.g.
'git ls-files --cached --ignored --exclude-standard') is greatly improved
as this no longer re-reads .gitignore files on each call.
Here's some performance data from the linux and WebKit repos (best of 10
runs on a Debian Linux on SSD, core.preloadIndex=true):

name-hash: stop storing trailing '/' on paths in index_state.dir_hash
When 5102c617 (Add case insensitivity support for directories when using
git status, 2010-10-03) added directories to the name-hash there was
only a single hash table in which both real cache entries and leading
directory prefixes were registered. To distinguish between the two types
of entries, directories were stored with a trailing '/'.
2092678c (name-hash.c: fix endless loop with core.ignorecase=true,
2013-02-28), however, moved directories to a separate hash table
(index_state.dir_hash) but retained the (now) redundant trailing '/',
thus callers continue to bear the burden of ensuring the slash's
presence before searching the index for a directory. Eliminate this
redundancy by storing paths in the dir-hash without the trailing '/'.
An important benefit of this change is that it eliminates undocumented
and dangerous behavior of dir.c:directory_exists_in_index_icase() in
which it assumes not only that it can validly access one character
beyond the end of its incoming directory argument, but also that that
character will unconditionally be a '/'. This perilous behavior was
"tolerated" because the string passed in by its lone caller always had a
'/' in that position, however, things broke [1] when 2eac2a4c (ls-files
-k: a directory only can be killed if the index has a non-directory,
2013-08-15) added a new caller which failed to respect the undocumented
assumption.

Convert "struct cache_entry *" to "const ..." wherever possible
I attempted to make index_state->cache[] a "const struct cache_entry **"
to find out how existing entries in index are modified and where. The
question I have is what do we do if we really need to keep track of on-disk
changes in the index. The result is
- diff-lib.c: setting CE_UPTODATE
- name-hash.c: setting CE_HASHED
- preload-index.c, read-cache.c, unpack-trees.c and
builtin/update-index: obvious
- entry.c: write_entry() may refresh the checked out entry via
fill_stat_cache_info(). This causes "non-const struct cache_entry
*" in builtin/apply.c, builtin/checkout-index.c and
builtin/checkout.c
- builtin/ls-files.c: --with-tree changes stagemask and may set
CE_UPDATE
Of these, write_entry() and its call sites are probably most
interesting because it modifies on-disk info. But this is stat info
and can be retrieved via refresh, at least for porcelain
commands. Other just uses ce_flags for local purposes.
So, keeping track of "dirty" entries is just a matter of setting a
flag in index modification functions exposed by read-cache.c. Except
unpack-trees, the rest of the code base does not do anything funny
behind read-cache's back.
The actual patch is less valueable than the summary above. But if
anyone wants to re-identify the above sites. Applying this patch, then
this:
diff --git a/cache.h b/cache.h

2. To collect ignored files.
3. When collecting ignored files, to check that an untracked directory
that potentially contains ignored files doesn't also contain untracked
files (i.e. isn't already listed as untracked).
Let's get rid of case 3 first.
Currently, read_directory_recursive returns a boolean whether a directory
contains the requested files or not (actually, it returns the number of
files, but no caller actually needs that), and DIR_SHOW_IGNORED specifies
what we're looking for.
To be able to test for both untracked and ignored files in a single scan,
we need to return a bit more info, and the result must be independent of
the DIR_SHOW_IGNORED flag.
Reuse the path_treatment enum as return value of read_directory_recursive.
Split path_handled in two separate values path_excluded and path_untracked
that don't change their meaning with the DIR_SHOW_IGNORED flag. We don't
need an extra value path_untracked_and_excluded, as directories with both
untracked and ignored files should be listed as untracked.
Rename path_ignored to path_none for clarity (i.e. "don't treat that path"
in contrast to "the path is ignored and should be treated according to
DIR_SHOW_IGNORED").
Replace enum directory_treatment with path_treatment. That's just another
enum with the same meaning, no need to translate back and forth.
In treat_directory, get rid of the extra read_directory_recursive call and
all the DIR_SHOW_IGNORED-specific code.
In read_directory_recursive, decide whether to dir_add_name path_excluded
or path_untracked paths based on the DIR_SHOW_IGNORED flag.
The return value of read_directory_recursive is the maximum path_treatment
of all files and sub-directories. In the check_only case, abort when we've
reached the most significant value (path_untracked).

Optimize directory listing with pathspec limiter.
The way things are set up, you can now pass a "pathspec" to the
"read_directory()" function. If you pass NULL, it acts exactly
like it used to do (read everything). If you pass a non-NULL
pointer, it will simplify it into a "these are the prefixes
without any special characters", and stop any readdir() early if
the path in question doesn't match any of the prefixes.
NOTE! This does *not* obviate the need for the caller to do the *exact*
pathspec match later. It's a first-level filter on "read_directory()", but
it does not do the full pathspec thing. Maybe it should. But in the
meantime, builtin-add.c really does need to do first
read_directory(dir, .., pathspec);
if (pathspec)
prune_directory(dir, pathspec, baselen);
ie the "prune_directory()" part will do the *exact* pathspec pruning,
while the "read_directory()" will use the pathspec just to do some quick
high-level pruning of the directories it will recurse into.

builtin-add: simplify (and increase accuracy of) exclude handling
Previously, the code would always set up the excludes, and then manually
pick through the pathspec we were given, assuming that non-added but
existing paths were just ignored. This was mostly correct, but would
erroneously mark a totally empty directory as 'ignored'.
Instead, we now use the collect_ignored option of dir_struct, which
unambiguously tells us whether a path was ignored. This simplifies the
code, and means empty directories are now just not mentioned at all.
Furthermore, we now conditionally ask dir_struct to respect excludes,
depending on whether the '-f' flag has been set. This means we don't have
to pick through the result, checking for an 'ignored' flag; ignored entries
were either added or not in the first place.
We can safely get rid of the special 'ignored' flags to dir_entry, which
were not used anywhere else.

Convert "struct cache_entry *" to "const ..." wherever possible
I attempted to make index_state->cache[] a "const struct cache_entry **"
to find out how existing entries in index are modified and where. The
question I have is what do we do if we really need to keep track of on-disk
changes in the index. The result is
- diff-lib.c: setting CE_UPTODATE
- name-hash.c: setting CE_HASHED
- preload-index.c, read-cache.c, unpack-trees.c and
builtin/update-index: obvious
- entry.c: write_entry() may refresh the checked out entry via
fill_stat_cache_info(). This causes "non-const struct cache_entry
*" in builtin/apply.c, builtin/checkout-index.c and
builtin/checkout.c
- builtin/ls-files.c: --with-tree changes stagemask and may set
CE_UPDATE
Of these, write_entry() and its call sites are probably most
interesting because it modifies on-disk info. But this is stat info
and can be retrieved via refresh, at least for porcelain
commands. Other just uses ce_flags for local purposes.
So, keeping track of "dirty" entries is just a matter of setting a
flag in index modification functions exposed by read-cache.c. Except
unpack-trees, the rest of the code base does not do anything funny
behind read-cache's back.
The actual patch is less valueable than the summary above. But if
anyone wants to re-identify the above sites. Applying this patch, then
this:

That happened in the case of a pathname that was ignored, and we did
not ask for "dir->show_ignored". That test used to be *together*
with the "DTYPE(de) != DT_DIR", but splitting the two tests up
means that we can do that (common) test before we even bother to
calculate the real dtype.
Of course, that optimization only matters for systems that don't
have, or don't fill in DTYPE properly.
I also clarified the real relationship between "exclude" and
"dir->show_ignored". It used to do
if (exclude != dir->show_ignored) {
..
which wasn't exactly obvious, because it triggers for two different
cases:
- the path is marked excluded, but we are not interested in ignored
files: ignore it
- the path is *not* excluded, but we *are* interested in ignored
files: ignore it unless it's a directory, in which case we might
have ignored files inside the directory and need to recurse
into it).
so this splits them into those two cases, since the first case
doesn't even care about the type.
I also made a the DT_UNKNOWN case a separate helper function,
and added some commentary to the cases.

ls-files -k: a directory only can be killed if the index has a non-directory
"ls-files -o" and "ls-files -k" both traverse the working tree down
to find either all untracked paths or those that will be "killed"
(removed from the working tree to make room) when the paths recorded
in the index are checked out. It is necessary to traverse the
working tree fully when enumerating all the "other" paths, but when
we are only interested in "killed" paths, we can take advantage of
the fact that paths that do not overlap with entries in the index
can never be killed.
The treat_one_path() helper function, which is called during the
recursive traversal, is the ideal place to implement an
optimization.
When we are looking at a directory P in the working tree, there are
three cases:
(1) P exists in the index. Everything inside the directory P in
the working tree needs to go when P is checked out from the
index.
(2) P does not exist in the index, but there is P/Q in the index.
We know P will stay a directory when we check out the contents
of the index, but we do not know yet if there is a directory
P/Q in the working tree to be killed, so we need to recurse.
(3) P does not exist in the index, and there is no P/Q in the index
to require P to be a directory, either. Only in this case, we
know that everything inside P will not be killed without
recursing.
Note that this helper is called by treat_leading_path() that decides
if we need to traverse only subdirectories of a single common
leading directory, which is essential for this optimization to be
correct. This caller checks each level of the leading path
component from shallower directory to deeper ones, and that is what
allows us to only check if the path appears in the index. If the
call to treat_one_path() weren't there, given a path P/Q/R, the real
traversal may start from directory P/Q/R, even when the index
records P as a regular file, and we would end up having to check if
any leading subpath in P/Q/R, e.g. P, appears in the index.

dir.c: git-status --ignored: don't scan the work tree three times
'git-status --ignored' recursively scans directories up to three times:
1. To collect untracked files.
2. To collect ignored files.
3. When collecting ignored files, to check that an untracked directory
that potentially contains ignored files doesn't also contain untracked
files (i.e. isn't already listed as untracked).
Let's get rid of case 3 first.
Currently, read_directory_recursive returns a boolean whether a directory
contains the requested files or not (actually, it returns the number of
files, but no caller actually needs that), and DIR_SHOW_IGNORED specifies
what we're looking for.
To be able to test for both untracked and ignored files in a single scan,
we need to return a bit more info, and the result must be independent of
the DIR_SHOW_IGNORED flag.
Reuse the path_treatment enum as return value of read_directory_recursive.
Split path_handled in two separate values path_excluded and path_untracked
that don't change their meaning with the DIR_SHOW_IGNORED flag. We don't
need an extra value path_untracked_and_excluded, as directories with both
untracked and ignored files should be listed as untracked.
Rename path_ignored to path_none for clarity (i.e. "don't treat that path"
in contrast to "the path is ignored and should be treated according to
DIR_SHOW_IGNORED").
Replace enum directory_treatment with path_treatment. That's just another
enum with the same meaning, no need to translate back and forth.
In treat_directory, get rid of the extra read_directory_recursive call and
all the DIR_SHOW_IGNORED-specific code.
In read_directory_recursive, decide whether to dir_add_name path_excluded
or path_untracked paths based on the DIR_SHOW_IGNORED flag.
The return value of read_directory_recursive is the maximum path_treatment
of all files and sub-directories. In the check_only case, abort when we've
reached the most significant value (path_untracked).

(1) P exists in the index. Everything inside the directory P in
the working tree needs to go when P is checked out from the
index.
(2) P does not exist in the index, but there is P/Q in the index.
We know P will stay a directory when we check out the contents
of the index, but we do not know yet if there is a directory
P/Q in the working tree to be killed, so we need to recurse.
(3) P does not exist in the index, and there is no P/Q in the index
to require P to be a directory, either. Only in this case, we
know that everything inside P will not be killed without
recursing.
Note that this helper is called by treat_leading_path() that decides
if we need to traverse only subdirectories of a single common
leading directory, which is essential for this optimization to be
correct. This caller checks each level of the leading path
component from shallower directory to deeper ones, and that is what
allows us to only check if the path appears in the index. If the
call to treat_one_path() weren't there, given a path P/Q/R, the real
traversal may start from directory P/Q/R, even when the index
records P as a regular file, and we would end up having to check if
any leading subpath in P/Q/R, e.g. P, appears in the index.

dir.c: git-status --ignored: don't scan the work tree three times
'git-status --ignored' recursively scans directories up to three times:
1. To collect untracked files.
2. To collect ignored files.
3. When collecting ignored files, to check that an untracked directory
that potentially contains ignored files doesn't also contain untracked
files (i.e. isn't already listed as untracked).
Let's get rid of case 3 first.
Currently, read_directory_recursive returns a boolean whether a directory
contains the requested files or not (actually, it returns the number of
files, but no caller actually needs that), and DIR_SHOW_IGNORED specifies
what we're looking for.
To be able to test for both untracked and ignored files in a single scan,
we need to return a bit more info, and the result must be independent of
the DIR_SHOW_IGNORED flag.
Reuse the path_treatment enum as return value of read_directory_recursive.
Split path_handled in two separate values path_excluded and path_untracked
that don't change their meaning with the DIR_SHOW_IGNORED flag. We don't
need an extra value path_untracked_and_excluded, as directories with both
untracked and ignored files should be listed as untracked.
Rename path_ignored to path_none for clarity (i.e. "don't treat that path"
in contrast to "the path is ignored and should be treated according to
DIR_SHOW_IGNORED").
Replace enum directory_treatment with path_treatment. That's just another
enum with the same meaning, no need to translate back and forth.
In treat_directory, get rid of the extra read_directory_recursive call and

Optimize directory listing with pathspec limiter.
The way things are set up, you can now pass a "pathspec" to the
"read_directory()" function. If you pass NULL, it acts exactly
like it used to do (read everything). If you pass a non-NULL
pointer, it will simplify it into a "these are the prefixes
without any special characters", and stop any readdir() early if
the path in question doesn't match any of the prefixes.
NOTE! This does *not* obviate the need for the caller to do the *exact*
pathspec match later. It's a first-level filter on "read_directory()", but
it does not do the full pathspec thing. Maybe it should. But in the
meantime, builtin-add.c really does need to do first
read_directory(dir, .., pathspec);
if (pathspec)
prune_directory(dir, pathspec, baselen);
ie the "prune_directory()" part will do the *exact* pathspec pruning,
while the "read_directory()" will use the pathspec just to do some quick
high-level pruning of the directories it will recurse into.

Avoid unnecessary "if-before-free" tests.
This change removes all obvious useless if-before-free tests.
E.g., it replaces code like this:
if (some_expression)
free (some_expression);
with the now-equivalent:
free (some_expression);
It is equivalent not just because POSIX has required free(NULL)
to work for a long time, but simply because it has worked for
so long that no reasonable porting target fails the test.
Here's some evidence from nearly 1.5 years ago:
http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html
FYI, the change below was prepared by running the following:
git ls-files -z | xargs -0 \
perl -0x3b -pi -e \
's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s'
Note however, that it doesn't handle brace-enclosed blocks like
"if (x) { free (x); }". But that's ok, since there were none like
that in git sources.
Beware: if you do use the above snippet, note that it can
produce syntactically invalid C code. That happens when the
affected "if"-statement has a matching "else".
E.g., it would transform this
if (x)
free (x);
else
foo ();
into this:
free (x);
else
foo ();
There were none of those here, either.
If you're interested in automating detection of the useless
tests, you might like the useless-if-before-free script in gnulib:
[it *does* detect brace-enclosed free statements, and has a --name=S
option to make it detect free-like functions with different names]
http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free

Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

dir.c: git-status --ignored: don't scan the work tree three times
'git-status --ignored' recursively scans directories up to three times:
1. To collect untracked files.
2. To collect ignored files.
3. When collecting ignored files, to check that an untracked directory
that potentially contains ignored files doesn't also contain untracked
files (i.e. isn't already listed as untracked).
Let's get rid of case 3 first.
Currently, read_directory_recursive returns a boolean whether a directory
contains the requested files or not (actually, it returns the number of
files, but no caller actually needs that), and DIR_SHOW_IGNORED specifies
what we're looking for.
To be able to test for both untracked and ignored files in a single scan,
we need to return a bit more info, and the result must be independent of
the DIR_SHOW_IGNORED flag.
Reuse the path_treatment enum as return value of read_directory_recursive.
Split path_handled in two separate values path_excluded and path_untracked
that don't change their meaning with the DIR_SHOW_IGNORED flag. We don't
need an extra value path_untracked_and_excluded, as directories with both
untracked and ignored files should be listed as untracked.
Rename path_ignored to path_none for clarity (i.e. "don't treat that path"
in contrast to "the path is ignored and should be treated according to
DIR_SHOW_IGNORED").
Replace enum directory_treatment with path_treatment. That's just another
enum with the same meaning, no need to translate back and forth.
In treat_directory, get rid of the extra read_directory_recursive call and
all the DIR_SHOW_IGNORED-specific code.
In read_directory_recursive, decide whether to dir_add_name path_excluded
or path_untracked paths based on the DIR_SHOW_IGNORED flag.
The return value of read_directory_recursive is the maximum path_treatment
of all files and sub-directories. In the check_only case, abort when we've
reached the most significant value (path_untracked).

Optimize directory listing with pathspec limiter.
The way things are set up, you can now pass a "pathspec" to the
"read_directory()" function. If you pass NULL, it acts exactly
like it used to do (read everything). If you pass a non-NULL
pointer, it will simplify it into a "these are the prefixes
without any special characters", and stop any readdir() early if
the path in question doesn't match any of the prefixes.
NOTE! This does *not* obviate the need for the caller to do the *exact*
pathspec match later. It's a first-level filter on "read_directory()", but
it does not do the full pathspec thing. Maybe it should. But in the
meantime, builtin-add.c really does need to do first
read_directory(dir, .., pathspec);
if (pathspec)
prune_directory(dir, pathspec, baselen);
ie the "prune_directory()" part will do the *exact* pathspec pruning,
while the "read_directory()" will use the pathspec just to do some quick
high-level pruning of the directories it will recurse into.

core.excludesfile clean-up
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().

config: allow inaccessible configuration under $HOME
The changes v1.7.12.1~2^2~4 (config: warn on inaccessible files,
2012-08-21) and v1.8.1.1~22^2~2 (config: treat user and xdg config
permission problems as errors, 2012-10-13) were intended to prevent
important configuration (think "[transfer] fsckobjects") from being
ignored when the configuration is unintentionally unreadable (for
example with EIO on a flaky filesystem, or with ENOMEM due to a DoS
attack). Usually ~/.gitconfig and ~/.config/git are readable by the
current user, and if they aren't then it would be easy to fix those
permissions, so the damage from adding this check should have been
minimal.
Unfortunately the access() check often trips when git is being run as
a server. A daemon (such as inetd or git-daemon) starts as "root",
creates a listening socket, and then drops privileges, meaning that
when git commands are invoked they cannot access $HOME and die with
fatal: unable to access '/root/.config/git/config': Permission denied
Any patch to fix this would have one of three problems:
1. We annoy sysadmins who need to take an extra step to handle HOME
when dropping privileges (the current behavior, or any other
proposal that they have to opt into).
2. We annoy sysadmins who want to set HOME when dropping privileges,
either by making what they want to do impossible, or making them
set an extra variable or option to accomplish what used to work
(e.g., a patch to git-daemon to set HOME when --user is passed).
3. We loosen the check, so some cases which might be noteworthy are
not caught.
This patch is of type (3).
Treat user and xdg configuration that are inaccessible due to
permissions (EACCES) as though no user configuration was provided at
all.
An alternative method would be to check if $HOME is readable, but that
would not help in cases where the user who dropped privileges had a
globally readable HOME with only .config or .gitconfig being private.
This does not change the behavior when /etc/gitconfig or .git/config
is unreadable (since those are more serious configuration errors),
nor when ~/.gitconfig or ~/.config/git is unreadable due to problems
other than permissions.
