graceful-fs functions as a drop-in replacement for the fs module, making various improvements.
The improvements are meant to normalize behavior across different platforms and environments, and to make filesystem access more resilient to errors.
graceful-fs:
open
and readdir
calls, and retries them once
something closes if there is an EMFILE error from too many file
descriptors.lchmod
for Node versions prior to 0.6.2.fs.lutimes
if possible. Otherwise it becomes a noop.EINVAL
and EPERM
errors in chown
, fchown
or
lchown
if the user isn't root.lchmod
and lchown
become noops, if not available.read
results in EAGAIN error.On Windows, it retries renaming a file for up to one second if EACCESS
or EPERM
error occurs, likely because antivirus software has locked
the directory.
