v0.3.0

A few bug fixes and a few new features.

Bug fixes:

• staticfs now compliant with 9P2000.L Linux kernel client (and tested to be).
• ede3efe contains fix for servers in use with Linux kernels built after 9/2020 walking open FIDs, which are spec-non-compliant.
• 218df7a allows server p9.File implementations to omit returning a QID on clones, as is spec-compliant.

Performance:

• 7d660a9 nudges clients to use msize-sized iounits for opened files for localfs.
• 78606c4 improved throughput by 13MB/s to 92MB/s (Linux kernel client over QEMU TCP) (d40d140 fixes the client bug introduced by this, also in this release).

Features:

• Locks & extended attributes are now supported, with new methods in p9.File to implement for servers (some help for xattr on local file systems in fsimpl/xattr)
  • Extended attributes are only supported by the server-side implementation. The client-side implementation is missing so far.
• composefs: a file system to compose disjoint files and file systems (i.e. p9.Files and p9.Attachers) into one 9P file server
