Release Notes

• [GLOBAL] Important notice: unless critical bugs are found, this will be the final Muster 8 release, development will switch to Muster 9 only
• [RENDERCLIENT] Fixed a bug in Windows that may produce a stall into the renders due to the way we collect the processes output. This is a rare condition but if you experience keep alive disconnections on the clients and/or the Dispatcher for an unknown reasons or you see that the client is stalled until the render is completed, the upgrade is mandatory. The bug is also present in Muster 8.6.19 and is marked as critical, that's why we also released a 8.6.20 version to address just this bug

• [DISPATCHER] Fixed a bug in the 'required by pool' taking into consideration even completed jobs and allocating nodes in the wrong way
• [DISPATCHER] Fixed an issue in the web interface not showing certain templates selectors
• [DISPATCHER] Fixed an issue in SSL connections where the web server was not able to completely parse the entire body request and failing a job submission
• [API] Fixed the behaviour of the chunkGet function in the console API where the database ID of the chunk was expected instead of the sequential chunk ID
• [CONSOLE] The pools filters now show the selected pools
• [RENDERCLIENT] The system events sent to Unix systems (Linux/Mac) are now configurable. In the past, we hardcoded commands like shutdown -rn now that under certain distributions caused a brutal stop of the machine and the offline status was not notified back to the Dispatcher correctly. We now default to init 0 and init 6
• [RENDERCLIENT] Fixed a regression bug with the logged user not being detected correctly

• [DISPATCHER] Fixed an issue when using the web server and/or the http REST APIs to download the chunks details. The previous code may introduce a memory leak and a subsequent process crash
• [DISPATCHER] Fixed an issue when using HTTPS in a multithread context. The previous code may introduce a race condition and a subsequent process crash

• [DISPATCHER] Fixed an issue where a job may be not flagged correctly as in-progress with warnings / errors under random circumstances
• [RENDERCLIENT] Included an option into the shutdown behaviours to include a timeout before detecting a logged user. This is useful to allow switching or logout of users for a certain amount of time before the shutdown begins

• [OSX] Support for the Dispatcher running on High Sierra

• [RENDERCLIENT] Fixed Shutdown/Restart functions on Linux and Mac, stucking the renderclient blocking a correct connection closure communication to the Dispatcher
• [RENDERCLIENT] Linux platform user login detection feature has been improved to skip detection on “dummy” users while on the login screen of certain distributions
• [RENDERCLIENT] Linux and Mac platforms have a new pipe handling function that works better and avoid skipping lines or stalling very fast processes, it also supports bigger chunks of logs and it's faster than the previous one
• [MAX] Fixed an issue with the Max connector not handling the Environmental variable and hanging the startup on recent Max versions
• [MRTOOL] Mrtool has a new flag, -waitdbflush, that waits until all the changes you made through an mrtool command are effectively flushed to the database, in case you need to query the DB after an mrtool command

• [CONSOLE] Templates and jobs exclusions list can now be purged with a multiple selection
• [CONSOLE] Chunk view now corrects open logs of historized chunks

Welcome to the first release of Muster 8. Muster 8 has several new features and a ground breaking new template system entirely based on Python 3.X. Muster 8 also has a brand new client API that let you access the Dispatcher service and the clients using your prefereed scripting language. Bindings are actually available for Python 2.X, Python 3.X, Java, .NET, Perl and PHP (PHP supported only on Unix platforms).

Be aware that there are some core changes between Muster 7.X and Muster 8. The queue database format is no longer compatible and it's not upgradable from a previous version. That means you'll need to rebuild your queue from scratch.Also Muster 8 supports builtin user groups as well as LDAP / Active Directory bindings for a superior authentication control.

The integrated web server is no longer built in inside Muster , but uses a brand new Javascript / JSON API that you can also use to interact with the Dispatcher in a similar way than the client API. The web server also, no longer uses a Java applet for file browsing, but relay on the new Repositories panel. That means you'll need to define a repository location even you're not using the substitution paths for cross platform renderings.

The major changes are on the template side. Instead of using a native scripting language, Muster 8 now uses Python 3.X for its templates. This opens a new way to customize Muster and a better control over the jobs processing.

This is a list of the new features:

• LDAP / Active directory support
• Console job caching for faster login
• Parallel rendering
• Muster API client library available to C++ / Python 3.x / Python 2.X / Java / Perl / PHP
• Python based template system
• Redesigned templates with improved engines support
• Users groups support
• Redesigned interface
• Global optimizations and enhancements in the code speed
