is there a way to read from a locked file?
when a length of -1 is specified for locking, does it mean that the whole
file is locked? even if the size changes?
i tried to read a file that was locked from offset 0 length -1 using the
same file object but failed…

You can memory map the file. Byte range locks are not enforced for memory
mapped files.
Byte range locks are identified by process as well as file object, so you’d
have to do it in the same process context for it to work correctly (and I’m
assuming you are not using a lock “key” which is optional.)
