# graceful-fs
|
|
|
|
|
|
|
|
|
|
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.

## Improvements over fs module
|
|
|
|
|
|
|
|
|
|
graceful-fs:
|
|
|
|
|
|
|
|
|
|
* Queues up `open` and `readdir` calls, and retries them once
|
|
|
|
|
something closes if there is an EMFILE error from too many file
|
|
|
|
|
descriptors.
|
|
|
|
|
* fixes `lchmod` for Node versions prior to 0.6.2.
|
|
|
|
|
* implements `fs.lutimes` if possible. Otherwise it becomes a noop.
|
|
|
|
|
* ignores `EINVAL` and `EPERM` errors in `chown`, `fchown` or
|
|
|
|
|
`lchown` if the user isn't root.
|
|
|
|
|
* makes `lchmod` and `lchown` become noops, if not available.
|
|
|
|
|
* retries reading a file if `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.
