File::NFSLock - perl module to do NFS (or not) locking
|
||
|
|
|
||
|
|
Program based of concept of hard linking of files being atomic
|
||
|
|
across NFS. This concept was mentioned in Mail::Box::Locker (which
|
||
|
|
was originally presented in Mail::Folder::Maildir). Some routine
|
||
|
|
flow is taken from there -- particularly the idea of creating a
|
||
|
|
random local file, hard linking a common file to the local file,
|
||
|
|
and then checking the nlink status. Some ideologies were not complete
|
||
|
|
(uncache mechanism, shared locking) and some coding was even
|
||
|
|
incorrect (wrong stat index). File::NFSLock was written to be light,
|
||
|
|
generic, and fast.
