The new release is ready,
Coda version 6.9.1
RPC2 version 2.4
RVM version 1.14
Sources, Debian i386 packages and FedoraCore 5 i386 rpms can be found at
ftp.coda.cs.cmu.edu:/pub/coda
Coda now works on 64-bit systems. The client and server were
successfully built and used on a machine with em64t extensions with a
64-bit Linux kernel. The new RVM-1.14 and RPC2-2.5 releases also
incorporate some essential 64-bit fixes.
Another welcome change is that venus now tries to keep cached access
rights available for users even across system reboot or client restart
which should improve life for people that frequently shut down or dual
boot their machines.
No changes for RVM data structures, it should be a matter of installing
the new versions and restarting your clients and servers.
Coda-6.9.1 changes::
* A lot of 64-bit related fixes.
* Allow access to cached files during disconnection if the user
currently has no valid tokens, but did have access before the
token expired.
* Add venus.conf options for the default reintegration time and age
parameters. Also increased default reintegration time to 5
seconds.
* New venus.conf option to allow backfetches (defaults to
'disallow'). The default reintegration behaviour for store
operations has been changed so that we always push new data to one
server and then trigger resolution to bring the other replicas in
sync. This push+resolve method uses less bandwidth, but is slower
on a fast network compared to the old behaviour where all replicas
connect back to the client and each would 'backfetch' a copy of
the new file data. Aside from the reduced bandwidth usage, pushing
the data from the client to the server makes file contents always
traverse over authenticated (and more secure) connections.
* cfs forcereintegrate failed to push the complete CML back to the
server when we are weakly connected. This was because
partialreintegrate (trickling a file back to one server and then
resolving) returned as soon as one chunk was pushed back.
* partialreintegration didn't fail when it encounted a server-server
conflict but instead restarted reintegration from the beginning of
the file.
* au command would segfault if no realm is specified.
* Reintegration for the local root user was extremely slow because
of a bad test.
* Changed naming of volume states, WriteDisconnected? is now
'Reachable', Disconnected is now 'Unreachable'.
* New venus.conf option 'isr'. This is a special feature when
running in a virtual machine. Before deleting a container file,
venus will first overwrite it with zeros. This should improve
compression of the VM disk-image. As this isn't very useful for
normal usage this option is disabled by default.
RPC2-2.5 changes::
* Incorporated several contributed fixes for the build process. On
systems with rpmbuild it should now be possible to enable the Lua
hooks by running rpmbuild --with lua. However I'm getting rpmbuild
failures when enabling that, so the prebuilt rpc2-2.5_1.i386.rpm
is built without Lua support.
* Default security setting has been changed to not allow the old
(XOR-based) handshake for new connections. If your server still
needs to allow clients that are still using a version or RPC2 that
is older than release 2.0 it is possible to re-enable the old
handshake by setting the RPC2SEC_ONLY environment variable to 'no'
(or 0, or false).
* Seed the PRNG by grabbing random data from /dev/urandom instead of
the blocking /dev/random device. This fixes issues with random
failures and timeouts especially while backups are running or
stuck Coda processes shortly after a reboot.
* And of course several 64-bit related fixes.
RVM-1.14 changes::
* Fix an overflow when freeing RVM allocated memory on 64-bit.
