when the pattern ended with one or more literal path components, or when the GLOB_MARK flag was passed to request that glob flag directory results and the type obtained by readdir was unknown or inconclusive (symlink), the stat function was called to evaluate existence and/or determine type. however, stat fails with ENOENT for broken symlinks, and this caused the match to be omitted from the results. instead, use stat only for the unknown/inconclusive cases with GLOB_MARK, and otherwise, or if stat fails, use lstat existence still needs to be determined. this minimizes the number of costly syscalls, performing both only in the case where GLOB_MARK is in use and there is a final literal path component which is a broken symlink. based on/simplified from patch by James Y Knight.
musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
the project website:
