With attr_timeout all files are empty at first read

[mitrandir77]

Before first read of the file stat always returns all-zero structure which is resulting in all files having size 0 in the first read. After first read of a file everything works just fine for it.

The problems seems to be a problem with att_timeout . When it's off on stat fuse is making two calls to getattr and stat syscall is returning correct numbers. For example:
$ stat -r file
1291845653 7 0100555 0 0 0 0 37344190 0 0 0 0 65536 72944 4294967295 file

When it's on only one call to getattr is done and stat syscall is returning almost all-zero stuct:
$ stat -r file
1325400088 0 0100000 0 0 0 0 0 0 0 0 0 0 0 0 file

The bug appeared in version of 2.7.3 of the kernel module. Version 2.7.2 works just fine.

Which file system are you observing the issue with? Are you by any chance using mount-time option noubcor nolocalcaches?

[mitrandir77]

I'm using proprietary filesystem written in D (it's using dfuse bindings to connect with fuse https://github.com/facebook/dfuse ).

My options are:
allow_other,negative_timeout=99999999,entry_timeout=99999999,attr_timeout=99999999,ac_attr_timeout=99999999,kernel_cache,noappledouble,noapplexattr,nobrowse

Thanks! I have fixed a bug that is most likely responsible for the observed getattr issue in osxfuse 2.7.3 and 2.7.4. It would be great if you could test the following osxfuse build and confirm that the issue is indeed gone: http://sourceforge.net/projects/osxfuse/files/osxfuse-2.7.5/osxfuse-2.7.5.dmg/download

Everything works as expected. Thank you! :)
