https://git.lua4.win/busybox-w32/atom?h=long_paths2026-02-27T14:27:40+00:00win32: add (some) long path support2026-02-27T14:27:40+00:00Ron Yorstonrmy@pobox.com2026-02-27T13:57:40+00:00urn:sha1:ed525e2db10081f095d2fccc1b02830654470401
Use the longPathAware manifest entry to handle path lengths above
260. This requires the LongPathsEnabled registry key to be set
at run-time.
Modify (some) WIN32 API calls to use the wide-character variant.
These features are controlled by the build-time configuration
option FEATURE_LONG_PATHS, which is not enabled by default.
win32: fake directories in readdir(2)2025-03-17T08:59:56+00:00Ron Yorstonrmy@pobox.com2025-03-17T08:59:56+00:00urn:sha1:3de63bc1739354df946c0b6dddd96058d8952bb7
The emulation of readdir(2) didn't include the '.' and '..'
directories in the root of a logical drive. This resulted in
the 'ls' applet (and others) not matching the expected Unix
behaviour.
Alter the emulation of readdir(2) to include fake '.' and '..'
directories if necessary.
Adds 88-112 bytes.

win32: missing support for "app exec link" reparse points2023-09-18T10:35:11+00:00Ron Yorstonrmy@pobox.com2023-09-18T10:35:11+00:00urn:sha1:1fcd57ab583a39f42b55f44d42472ea64e228c84
Commit 603af9bb9 (win32: support "app exec link" reparse points)
added support for IO_REPARSE_TAG_APPEXECLINK reparse points by
pretending they're symbolic links.
One change was missed, in the implementation of dirent.
Costs 16 bytes.
win32: always allow d_type member of struct dirent2022-12-22T11:38:39+00:00Ron Yorstonrmy@pobox.com2022-12-22T11:38:39+00:00urn:sha1:67aec6403c80b8956b8b0f78f58e2b9664bd4f62
The d_type member of struct dirent is required by the implementation
of glob(3). As a result it isn't possible to build the make applet
unless FEATURE_EXTRA_FILE_DATA is configured.
Allow d_type unconditionally.
win32: try to get link count for directories2022-05-15T07:52:26+00:00Ron Yorstonrmy@pobox.com2022-05-15T07:52:26+00:00urn:sha1:7fb95a2a569ca6d68dad4cef5b7b299e9fe68e2b
On Unix the link count of a directory reflects the number of
subdirectories it contains. Enhance readdir(3) to return file
types and use this to count subdirectories when stat(2) is called
for a directory.
As with other features that might slow down stat(2) this is
controlled by the build-time setting FEATURE_EXTRA_FILE_DATA.
(Commit d82db8e9a 'win32: make stat(2) fetch additional metadata').

win32: add local dirent implementation2021-06-13T07:13:25+00:00Ron Yorstonrmy@pobox.com2021-06-13T07:13:25+00:00urn:sha1:f7e4fe39a69b82bcef1aaa68111ccfa68b209ada
Add a cut down version of the dirent implementation from git.
The git developers said:
The mingw-runtime implemenation of opendir, readdir and closedir
sets errno to 0 on success, something that POSIX explicitly
forbids.
This also avoids having to link against libssp.a (commit 13eb34205)
and reduces the size of the binary by 2KB.
