# 1.12 18-Oct-2016 manu

branches: 1.12.14;
Make FUSE socket buffer tunable

When dealing with high I/O throughput, we could run out of buffer
space if the filesystem was not consuming requests fast enough.
Here we slightly raise the buffer size, and we make it tunable
through the PERFUSE_BUFSIZE environment variable so that we can
cope with higher requirement later.

While there, document PERFUSE_OPTIONS environment variable.

# 1.10 29-Jan-2012 manu

Improve FUSE trace facility


# 1.9 28-Dec-2011 wiz

Improve markup, remove tailing whitespace.


# 1.8 28-Dec-2011 manu

Add a FUSE trace facility, with statistics collection. This should help
tracking bugs and performance issues

# 1.4 27-Aug-2010 wiz

Various fixes and improvements.


# 1.3 27-Aug-2010 manu

- if perfused is not already started (cannot connect to /dev/fuse),
FUSE filesystems will attempt to start it on their own, and will
communicate using a socketpair

- do not advertise NULL file handle as being valid when sending themback to the FUSE filesystem.

- unmount if we cannot talk to the FUSE process anymore

- set calling process gid properly

- debug message cleanup


# 1.2 26-Aug-2010 manu

- open the file before doing fsync: glusterfs wants that.

- Automatically call fsync on close for files. If we just close, fsync
will come later and we will have to reopen

- Add a PND_DIRTY flag to keep track of files that really need a sync.
perfuse_node_fsync only calls the FUSE fsync method if there are data
to push.

- Add a PND_OPEN flag to keep track of open files. Checking non NULL
fh is not enough, as some filesystems will always set fh to 0.

- Add a sync diagnostic flag, to watch fsync and dirty flag activity.
Make the fh diagnostic flag more verbose

- Send the fh in setattr (it was hardcoded to 0)

I am now able to build libperfuse in a glusterfs mounted filesystem. Yeah!


# 1.1 25-Aug-2010 manu

perfused(8) creates a /dev/fuse socket and performs PUFFS to FUSE relaying.
This is still a work in progress.
