CFEngine Community 3.3.0 is now available for download. New promise types: - Guest environments promises, which allow to manipulate virtual machines using libvirt. - Database promises, which allow to maintain schema of MySQL and PostgreSQL databases. Database promises are in "technical preview" status: this promise type is subject to change in future. - Services promises for Unix, allows abstraction of details on managing any service. New built-in functions: - dirname() to complement lastnode(). - lsdir(). - maplist() to apply functions over lists. New features: - Allow defining arrays from modules. - Allow both `process_stop' and `signals' constraints in `processes' promises at the same time. - cf-promises --gcc-brief-format option to output warnings and errors in gcc-compatible syntax which to ease use "go to next error" feature of text editors. - Iteration over lists is now allowed for qualified (non-local) lists. New built-in variables and classes (Linux): - Number of CPUs: $(sys.cpus), 1_cpu, 2_cpus etc. New built-in variables and classes (Unices): - $(sys.last_policy_update) - timestamp when last policy change was seen by host. - $(sys.hardware_addresses) - list of MAC adresses. - $(sys.ip_addresses) - list of IP addresses. - $(sys.interfaces) - list of network interfaces. - $(sys.hardware_mac[$iface]) - MAC address for network interface. - mac_:: - discovered MAC addresses. Changes: - Major cleanup of database handling code. Should radically decrease amount of database issues experienced under heavy load. *WARNING*: Berkeley DB and SQLite backends are *removed*, use Tokyo Cabinet or QDBM instead. Both Tokyo Cabinet and QDBM are faster than Berkeley DB in typical CFEngine workloads. Tokyo Cabinet requires C99 environment, so it should be available on every contemporary operating system. For the older systems QDBM, which relies only on C89, is a better replacement, and deemed to be as portable, as Berkeley DB. - Change of lastseen database schema. Should radically decrease I/O contention on lasteen database. - Automatic reload of policies by cf-execd. - Documentation is generated during build, PDF and HTML files are retired from repository. - Rarely used feature retired: peer connectivity intermittency calculation. - Memory and CPU usage improvements. - Testsuite now uses 'make check' convention and does not need root privileges anymore. - cf_promises_validated now filled with timestamp, allows digest-copy for policy instead of mtime copy which is safer when clocks are unsynchronised. - The bundled failsafe.cf policy now has trustkey=false to avoid IP spoofing attacks in default policy. - See the full list of bugfixes at Bugfixes Downloads: Source Code Checksums: MD5 d40426fcc447e6f1581a6abd6116ea20 cfengine-3.3.0.tar.gz SHA1 15ac009acaebf8fb402c23f3632470555bc48ecb cfengine-3.3.0.tar.gz _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
