be8a84c526 dir.c: make 'git-status --ignored' work within leading directories
'git-status --ignored path/' doesn't list ignored files and directories
within 'path' if some component of 'path' is classified as untracked.

Disable the DIR_SHOW_OTHER_DIRECTORIES flag while traversing leading
directories. This prevents treat_leading_path() with DIR_SHOW_IGNORED flag
from aborting at the top level untracked directory.

As a side effect, this also eliminates a recursive directory scan per
leading directory level, as treat_directory() can no longer call
read_directory_recursive() when called from treat_leading_path().

c94ab01026 dir.c: git-status --ignored: don't list empty directories as ignored
'git-status --ignored' lists empty untracked directories as ignored, even
though they don't have any ignored files.

When checking if a directory is already listed as untracked (i.e. shouldn't
be listed as ignored as well), don't assume that the directory has only
ignored files if it doesn't have untracked files, as the directory may be
empty.

4698c8feb1 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.

9a6728d4d1 rm: do not complain about d/f conflicts during deletion
If we used to have an index entry "d/f", but "d" has been
replaced by a non-directory entry, the user may still want
to run "git rm" to delete the stale index entry. They could
use "git rm --cached" to just touch the index, but "git rm"
should also work: we explicitly try to handle the case that
the file has already been removed from the working tree.

However, because unlinking "d/f" in this case will not yield
ENOENT, but rather ENOTDIR, we do not notice that the file
is already gone. Instead, we report it as an error.

The simple solution is to treat ENOTDIR in this case exactly
like ENOENT; all we want to know is whether the file is
already gone, and if a leading path is no longer a
directory, then by definition the sub-path is gone.

ab3aebc15c dir.c::match_pathname(): pay attention to the length of string parameters
This function takes two counted strings: a <pattern, patternlen> pair
and a <pathname, pathlen> pair. But we end up feeding the result to
fnmatch, which expects NUL-terminated strings.

We can fix this by calling the fnmatch_icase_mem function, which
handles re-allocating into a NUL-terminated string if necessary.

While we're at it, we can avoid even calling fnmatch in some cases. In
addition to patternlen, we get "prefix", the size of the pattern that
contains no wildcard characters. We do a straight match of the prefix
part first, and then use fnmatch to cover the rest. But if there are
no wildcards in the pattern at all, we do not even need to call
fnmatch; we would simply be comparing two empty strings.

982ac87316 dir.c::match_pathname(): adjust patternlen when shifting pattern
If we receive a pattern that starts with "/", we shift it
forward to avoid looking at the "/" part. Since the prefix
and patternlen parameters are counts of what is in the
pattern, we must decrement them as we increment the pointer.

We remembered to handle prefix, but not patternlen. This
didn't cause any bugs, though, because the patternlen
parameter is not actually used. Since it will be used in
future patches, let's correct this oversight.

0b6e56dfe6 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.

a45fb697f1 status: always report ignored tracked directories
When enumerating paths that are ignored, paths the index knows
about are not included in the result.  The "index knows about"
check is done by consulting the name hash, not the actual
contents of the index:

 - When core.ignorecase is false, directory names are not in the
   name hash, and ignored ones are shown as ignored (directories
   can never be tracked anyway).

 - When core.ignorecase is true, however, the name hash keeps
   track of the names of directories, in order to detect
   additions of the paths under different cases.  This causes
   ignored directories to be mistakenly excluded when
   enumerating ignored paths.

Stop excluding directories that are in the name hash when
looking for ignored files in dir_add_name(); the names that are
actually in the index are excluded much earlier in the callchain
in treat_file(), so this fix will not make them mistakenly
identified as ignored.

c04318e46a dir.c: keep track of where patterns came from
For exclude patterns read in from files, the filename is stored in the
exclude list, and the originating line number is stored in the
individual exclude (counting starting at 1).

For exclude patterns provided on the command line, a string describing
the source of the patterns is stored in the exclude list, and the
sequence number assigned to each exclude pattern is negative, with
counting starting at -1.  So for example the 2nd pattern provided via
--exclude would be numbered -2.  This allows any future consumers of
that data to easily distinguish between exclude patterns from files
vs. from the CLI.

c082df2453 dir.c: use a single struct exclude_list per source of excludes
Previously each exclude_list could potentially contain patterns
from multiple sources.  For example dir->exclude_list[EXC_FILE]
would typically contain patterns from .git/info/exclude and
core.excludesfile, and dir->exclude_list[EXC_DIRS] could contain
patterns from multiple per-directory .gitignore files during
directory traversal (i.e. when dir->exclude_stack was more than
one item deep).

We split these composite exclude_lists up into three groups of
exclude_lists (EXC_CMDL / EXC_DIRS / EXC_FILE as before), so that each
exclude_list now contains patterns from a single source.  This will
allow us to cleanly track the origin of each pattern simply by adding
a src field to struct exclude_list, rather than to struct exclude,
which would make memory management of the source string tricky in the
EXC_DIRS case where its contents are dynamically generated.

Similarly, by moving the filebuf member from struct exclude_stack to
struct exclude_list, it allows us to track and subsequently free
memory buffers allocated during the parsing of all exclude files,
rather than only tracking buffers allocated for files in the EXC_DIRS
group.

721ac4edde dir.c: Make git-status --ignored more consistent
The current behavior of git-status is inconsistent and misleading.
Especially when used with --untracked-files=all option:

 - files ignored in untracked directories will be missing from

 - untracked files in committed yet ignored directories are also
   missing.

 - with --untracked-files=normal, untracked directories that
   contains only ignored files are dropped too.

Make the behavior more consistent across all possible use cases:

 - "--ignored --untracked-files=normal" doesn't show each specific
   files but top directory.  It instead shows untracked directories
   that only contains ignored files, and ignored tracked directories
   with untracked files.

 - "--ignored --untracked-files=all" shows all ignored files, either
   because it's in an ignored directory (tracked or untracked), or

823ab40fd4 add global --literal-pathspecs option
Git takes pathspec arguments in many places to limit the
scope of an operation. These pathspecs are treated not as
literal paths, but as glob patterns that can be fed to
fnmatch. When a user is giving a specific pattern, this is a
nice feature.

However, when programatically providing pathspecs, it can be
a nuisance. For example, to find the latest revision which
modified "$foo", one can use "git rev-list -- $foo". But if
"$foo" contains glob characters (e.g., "f*"), it will
erroneously match more entries than desired. The caller
needs to quote the characters in $foo, and even then, the
results may not be exactly the same as with a literal
pathspec. For instance, the depth checks in
match_pathspec_depth do not kick in if we match via fnmatch.

This patch introduces a global command-line option (i.e.,
one for "git" itself, not for specific commands) to turn
this behavior off. It also has a matching environment
variable, which can make it easier if you are a script or
porcelain interface that is going to issue many such
commands.

This option cannot turn off globbing for particular
pathspecs. That could eventually be done with a ":(noglob)"
magic pathspec prefix. However, that level of granularity is
more cumbersome to use for many cases, and doing ":(noglob)"
right would mean converting the whole codebase to use
"struct pathspec", as the usual "const char **pathspec"
cannot represent extra per-item flags.

8c6abbcd27 pathspec: apply "*.c" optimization from exclude
When a pattern contains only a single asterisk as wildcard,
e.g. "foo*bar", after literally comparing the leading part "foo" with
the string, we can compare the tail of the string and make sure it
matches "bar", instead of running fnmatch() on "*bar" against the
remainder of the string.

-O2 build on linux-2.6, without the patch:

$ time git rev-list --quiet HEAD -- '*.c'

real    0m40.770s
user    0m40.290s
sys     0m0.256s

With the patch

$ time ~/w/git/git rev-list --quiet HEAD -- '*.c'

real    0m34.288s
user    0m33.997s
sys     0m0.205s

The above command is not supposed to be widely popular. It's chosen
because it exercises pathspec matching a lot. The point is it cuts
down matching time for popular patterns like *.c, which could be used
as pathspec in other places.

82dce998c2 attr: more matching optimizations from .gitignore
.gitattributes and .gitignore share the same pattern syntax but has
separate matching implementation. Over the years, ignore's
implementation accumulates more optimizations while attr's stays the
same.

This patch reuses the core matching functions that are also used by
excluded_from_list. excluded_from_list and path_matches can't be
merged due to differences in exclude and attr, for example:

* "!pattern" syntax is forbidden in .gitattributes.  As an attribute
  can be unset (i.e. set to a special value "false") or made back to
  unspecified (i.e. not even set to "false"), "!pattern attr" is unclear
  which one it means.

* we support attaching attributes to directories, but git-core
  internally does not currently make use of attributes on
  directories.

could become tiring to see the warning on the same path over and

responsible for issuing this warning, we could later choose to keep
track of which paths we issued a warning (it would involve a hash
table of paths after running them through real_path() or something)
in order to reduce noise.

Right now we do not know if the noise reduction is necessary, but it

dc79687e0b Let core.excludesfile default to $XDG_CONFIG_HOME/git/ignore
To use the feature of core.excludesfile, the user needs:

 1. to create such a file,

 2. and add configuration variable to point at it.

Instead, we can make this a one-step process by choosing a default value
which points to a filename in the user's $HOME, that is unlikely to
already exist on the system, and only use the presence of the file as a
cue that the user wants to use that feature.

And we use "${XDG_CONFIG_HOME:-$HOME/.config/git}/ignore" as such a
file, in the same directory as the newly added configuration file
("${XDG_CONFIG_HOME:-$HOME/.config/git}/config).  The use of this
directory is in line with XDG specification as a location to store
such application specific files.

eb41775ecc ls-files -i: pay attention to exclusion of leading paths
"git ls-files --exclude=t/ -i" does not show paths in directory t/
that have been added to the index, but it should.

The excluded() API was designed for callers who walk the tree from
the top, checking each level of the directory hierarchy as it
descends if it is excluded, and not even bothering to recurse into
an excluded directory.  This would allow us optimize for a common
case by not having to check if the exclude pattern "foo/" matches
when looking at "foo/bar", because the caller should have noticed
that "foo" is excluded and did not even bother to read "foo/bar"
out of opendir()/readdir() to call it.

The code for "ls-files -i" however walks the index linearly, feeding
paths without checking if the leading directory is already excluded.

Introduce a helper function path_excluded() to let this caller
properly call excluded() check for higher hierarchies as necessary.

49dc2cc2c9 dir: convert to strbuf
The functions read_directory_recursive() and treat_leading_path() both
use buffers sized to fit PATH_MAX characters.  The latter can be made to
overrun its buffer, e.g. like this:

	$ a=0123456789abcdef
	$ a=$a$a$a$a$a$a$a$a
	$ a=$a$a$a$a$a$a$a$a
	$ a=$a$a$a$a$a$a$a$a
	$ git add $a/a

Instead of trying to add a check and potentionally forgetting to address
similar cases, convert the involved functions and their helpers to use
struct strbuf.  The patch is suprisingly large because the helpers
treat_path() and treat_one_path() modify the buffer as well and thus need
to be converted, too.

ae2f203ef7 clean: preserve nested git worktree in subdirectories
remove_dir_recursively() has a check to avoid removing the directory it
was asked to remove without recursing into it and report success when the
directory is the top level of a working tree of a nested git repository,
to protect such a repository from "clean -f" (without double -f). If a
working tree of a nested git repository is in a subdirectory of a toplevel
project, however, this protection did not apply by mistake; we forgot to
pass the REMOVE_DIR_KEEP_NESTED_GIT down to the recursive removal
codepath.

This requires us to also teach the higher level not to remove the
directory it is asked to remove, when the recursed invocation did not
remove the directory it was asked to remove due to a nested git
repository, as it is not an error to leave the parent directories of such
a nested repository.

33e0f62ba9 pathspec: rename per-item field has_wildcard to use_wildcard
As the point of the last change is to allow use of strings as
literals no matter what characters are in them, "has_wildcard"
does not match what we use this field for anymore.

It is used to decide if the wildcard matching should be used, so
rename it to match the usage better.

match_pathspec_depth() is a clone of match_pathspec() except that it
can take depth limit. Computation is a bit lighter compared to
match_pathspec() because it's usually precomputed and stored in struct

86e4ca69e3 tree_entry_interesting(): fix depth limit with overlapping pathspecs
Suppose we have two pathspecs 'a' and 'a/b' (both are dirs) and depth
limit 1. In current code, pathspecs are checked in input order. When
'a/b' is checked against pathspec 'a', it fails depth limit and
therefore is excluded, although it should match 'a/b' pathspec.

This patch reorders all pathspecs alphabetically, then teaches
tree_entry_interesting() to check against the deepest pathspec first,
so depth limit of a shallower pathspec won't affect a deeper one.

fbbb4e19be get_cwd_relative(): do not misinterpret root path
Commit 490544b (get_cwd_relative(): do not misinterpret suffix as
subdirectory) handles case where:

dir = "/path/work";
cwd = "/path/work-xyz";

When it comes to the end of get_cwd_relative(), dir is at '\0' and cwd
is at '-'. The rest of cwd, "-xyz", clearly cannot be the relative
path from dir to cwd. However there is another case where:

dir = "/";          /* or even "c:/" */
cwd = "/path/to/here";

In this special case, while *cwd == 'p', which is not a path
separator, the rest of cwd, "path/to/here", can be returned as a
relative path from dir to cwd.

Handle this case and make t1509 pass again.

5102c6173c Add case insensitivity support for directories when using git status
When using a case preserving but case insensitive file system, directory
case can differ but still refer to the same physical directory.  git
status reports the directory with the alternate case as an Untracked
file.  (That is, when mydir/filea.txt is added to the repository and
then the directory on disk is renamed from mydir/ to MyDir/, git status
shows MyDir/ as being untracked.)

Support has been added in name-hash.c for hashing directories with a
terminating slash into the name hash. When index_name_exists() is called
with a directory (a name with a terminating slash), the name is not
found via the normal cache_name_compare() call, but it is found in the
slow_same_name() function.

Additionally, in dir.c, directory_exists_in_index_icase() allows newly
added directories deeper in the directory chain to be identified.

Ultimately, it would be better if the file list was read in case
insensitive alphabetical order from disk, but this change seems to
suffice for now.

The end result is the directory is looked up in a case insensitive
manner and does not show in the Untracked files list.

10d4b02b99 Case insensitivity support for .gitignore via core.ignorecase
This is especially beneficial when using Windows and Perforce and the
git-p4 bridge. Internally, Perforce preserves a given file's full path
including its case at the time it was added to the Perforce repository.
When syncing a file down via Perforce, missing directories are created,
if necessary, using the case as stored with the filename. Unfortunately,
two files in the same directory can have differing cases for their
respective paths, such as /diRa/file1.c and /DirA/file2.c. Depending on
sync order, DirA/ may get created instead of diRa/.

It is possible to handle directory names in a case insensitive manner
without this patch, but it is highly inconvenient, requiring each
character to be specified like so: [Bb][Uu][Ii][Ll][Dd]. With this patch, the
gitignore exclusions honor the core.ignorecase=true configuration
setting and make the process less error prone. The above is specified
like so: Build

8cf2a84e9d Add string comparison functions that respect the ignore_case variable.
Multiple locations within this patch series alter a case sensitive
string comparison call such as strcmp() to be a call to a string
comparison call that selects case comparison based on the global
ignore_case variable. Behaviorally, when core.ignorecase=false, the
*_icase() versions are functionally equivalent to their C runtime
counterparts.  When core.ignorecase=true, the *_icase() versions perform
a case insensitive comparison.

Like Linus' earlier ignorecase patch, these may ignore filename
conventions on certain file systems. By isolating filename comparisons
to certain functions, support for those filename conventions may be more
easily met.

42f9852f3c common_prefix: simplify and fix scanning for prefixes
common_prefix() scans backwards from the far end of each 'next'
pathspec, starting from 'len', shortening the 'prefix' using 'path' as
a reference.

However, there is a small opportunity for an out-of-bounds access
because len is unconditionally set to prefix-1 after a "direct match"
test failed.  This means that if 'next' is shorter than prefix+2, we
read past it.

Instead of a minimal fix, simplify the loop: scan *forward* over the
'next' entry, remembering the last '/' where it matched the prefix
known so far.  This is far easier to read and also has the advantage
that we only scan over each entry once.

Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX

enum style is inconsistent already, with some enums declared on one

sometimes with 1 enum value per line... and independently of that the
trailing comma is sometimes present and other times absent, often
mixing with/without trailing comma styles in a single file, and
sometimes in consecutive enum declarations.

Clearly, omitting the comma is the more portable style, and this patch
changes all enum declarations to use the portable omitted dangling
comma style consistently.

29209cbe58 dir: fix COLLECT_IGNORED on excluded prefixes
As we walk the directory tree, if we see an ignored path, we
want to add it to the ignored list only if it matches any
pathspec that we were given. We used to check for the
pathspec to appear explicitly. E.g., if we see "subdir/file"
and it is excluded, we check to see if we have "subdir/file"
in our pathspec.

However, this interacts badly with the optimization to avoid
recursing into ignored subdirectories. If "subdir" as a
whole is ignored, then we never recurse, and consider only
whether "subdir" itself is in our pathspec.  It would not
match a pathspec of "subdir/file" explicitly, even though it
is the reason that subdir/file would be excluded.

This manifests itself to the user as "git add subdir/file"
failing to correctly note that the pathspec was ignored.

This patch extends the in_pathspec logic to include prefix
directory case.

Commit b5041c5 (Avoid writing to buffer in add_excludes_from_file_1())
tried not to append '\n' at the end because the next commit
may return a buffer that does not have extra space for that.

Unfortunately it left this assignment in the loop:

  buf[i - (i && buf[i-1] == '\r')] = 0;

that can corrupt memory if "buf" is not '\n' terminated. But even if
it does not corrupt memory, the last line would not be
NULL-terminated, leading to errors later inside add_exclude().

This patch fixes it by reverting the faulty commit and make
sure "buf" is always \n terminated.

While at it, free unused memory properly.

48ffef966c ls-files: fix overeager pathspec optimization
Given pathspecs that share a common prefix, ls-files optimized its call
into recursive directory reader by starting at the common prefix
directory.

If you have a directory "t" with an untracked file "t/junk" in it, but the
top-level .gitignore file told us to ignore "t/", this resulted in:

    $ git ls-files -o --exclude-standard
    $ git ls-files -o --exclude-standard t/
    t/junk
    $ git ls-files -o --exclude-standard t/junk
    t/junk
    $ cd t && git ls-files -o --exclude-standard
    junk

We could argue that you are overriding the ignore file by giving a
patchspec that matches or being in that directory, but it is somewhat
unexpected.  Worse yet, these behave differently:

    $ git ls-files -o --exclude-standard t/ .
    $ git ls-files -o --exclude-standard t/
    t/junk

This patch changes the optimization so that it notices when the common
prefix directory that it starts reading from is an ignored one.

it would segfault), dtype NULL will be used to say "hey.. you are

c28b3d6e7b Read .gitignore from index if it is skip-worktree
This adds index as a prerequisite for directory listing (with
exclude).  At the moment directory listing is used by "git clean",
"git add", "git ls-files" and "git status"/"git commit" and
unpack_trees()-related commands.  These commands have been
checked/modified to populate index before doing directory listing.

add_excludes_from_file() does not enable this feature, because it
is used to read .git/info/exclude and some explicit files specified
by "git ls-files".

1d8842d921 Add 'fill_directory()' helper function for directory traversal
Most of the users of "read_directory()" actually want a much simpler
interface than the whole complex (but rather powerful) one.

In fact 'git add' had already largely abstracted out the core interface
issues into a private "fill_directory()" function that was largely
applicable almost as-is to a number of callers.  Yes, 'git add' wants to
do some extra work of its own, specific to the add semantics, but we can
easily split that out, and use the core as a generic function.

This function does exactly that, and now that much simplified
'fill_directory()' function can be shared with a number of callers,
while also ensuring that the rather more complex calling conventions of
read_directory() are used by fewer call-sites.

This also makes the 'common_prefix()' helper function private to dir.c,
since all callers are now in that file.

6e4f981ffb git-add: no need for -f when resolving a conflict in already tracked path
When a path F that matches ignore pattern has a conflict, "git add F"
insisted the -f option be given, which did not make sense.  It would have
required -f when the path was originally added, but when resolving a
conflict, it already is tracked.

So this should work (and does):

  $ echo file >.gitignore
  $ echo content >file
  $ git add -f file ;# need -f because we are adding new path
  $ echo more content >>file
  $ git add file ;# don't need -f; it is not actually an "other" file

This is handled under the hood by the COLLECT_IGNORED option to
read_directory. When that code finds an ignored file, it checks the
index to make sure it is not actually a tracked file. However, the test
it uses does not take into account unmerged entries, and considers them
to still be ignored. "git ls-files" uses a more elaborate test and gets
the right answer and the same test should be used here.

da4b3e8c28 dir.c: clean up handling of 'path' parameter in read_directory_recursive()
Right now we pass two different pathnames ('path' and 'base') down to
read_directory_recursive(), and the only real reason for that is that we
want to allow an empty 'base' parameter, but when we do so, we need the
pathname to "opendir()" to be "." rather than the empty string.

And rather than handle that confusion in the caller, we can just fix
read_directory_recursive() to handle the case of an empty path itself,
by just passing opendir() a "." ourselves if the path is empty.

This would allow us to then drop one of the pathnames entirely from the
calling convention, but rather than do that, we'll start separating them
out as a "filesystem pathname" (the one we use for filesystem accesses)
and a "git internal base name" (which is the name that we use for git
internally).

That will eventually allow us to do things like handle different
encodings (eg the filesystem pathnames might be Latin1, while git itself
would use UTF-8 for filename information).

dd482eeac2 Support "\" in non-wildcard exclusion entries
"\" was treated differently in exclude rules depending on whether a
wildcard match was done. For wildcard rules, "\" was de-escaped in
fnmatch, but this was not done for other rules since they used strcmp
instead.  A file named "#foo" would not be excluded by "\#foo", but would
be excluded by "\#foo*".

We now treat all rules with "\" as wildcard rules.

Another solution could be to de-escape all non-wildcard rules as we
read them, but we would have to do the de-escaping exactly as fnmatch
does it to avoid inconsistencies.

The new name contains underscores because they enhance readability
