Hello,
We are very happy to announce an RC2 testing release of the Spread Toolkit version 4.2.0.
This RC2 release is publicly available from a download from the public SVN repo
as the tagged release svn+ssh://svn.spread.org/spread/tags/RC2_4_2_0
or from the Spread website (http://www.spread.org/download.html) as a tar.gz package
by selecting the "Older Spread Releases" option (we will update the website
soon to make this clearer)
This RC2 release has all planned changes, fixes and updates already included so if no
problems are found we plan to release this as the final release in a week or two.
Therefore, we would encourage everyone to try this release out over the next week or two and
let us know if you find any regressions or problems as it includes a number
of bug fixes and we would like it to be a stable release when finalized.
The Spread 4.2 release is an important bugfix release for the Spread project.
This release has a large number of small changes which include bugfixes,
very specific performance improvements, and general improvements to the code
and build process.
The main new features of this release are:
1) Added Keepalive support to client-server TCP connections. Requires correct
operating system values set for keepalives in order to be useful.
2) Switch internal code to use MONOTONIC clocks when available and appropriate
to remove chance of system clock changes (from the clock being set) from affecting
message processing
3) Break out events, memory, data_link and alarm code into separate
libspread-util package. This package also has a number of improvements in
the functionality of those code files which are listed in the internal
package release notes.
It also includes a number of important bug fixes. The most significant include:
1) Fix bug with structure size on 64 bit platforms causing crash.
2) Fix several deadlock, crashes and race conditions in java Listener code.
3) Fix 100 ms timeout in java socket handling code so it does not corrupt
messages that take a long time to arrive.
4) Fix java disconnect bug that prevented client from reconnecting until restarted.
5) Remove cause of slow message delivery when a client is receiving a lot of
messages and gets into a badger state.
6) Improve help output and error messages in utility programs.
7) Fix token hurry bug that caused messages to have a 2 second latency in
specific circumstances.
8) Fix crash bug when new daemon configuration files are loaded while the
system is running.
Cheers,
Jonathan
