3.6.2
Bug fixes:
- don't regenerate software_packages.csv every time (Redmine #6441)
- improve verbose message for package_list_command
- fix missing log output on AIX (Redmine #6434)
- assorted fixes to dirname() esp on Windows (Redmine #4716)
- fix package manager detection
- fix build issues on FreeBSD
- allow copying of dead symbolic links (Redmine #6175)
- preserve order in readstringarrayidx (Redmine #6466)
- fix passing of unexpanded variable references to arrays
(Redmine #5893)
- use entries for new {admin,deny}_{ips,hostnames} constraints in
the relevant legacy lists (Redmine #6542)
- cope with ps's numeric fields overflowing to the right
- interpret failing function calls in ifvarclass as class not set
(Redmine #6327)
- remove unexpanded lists when extending lists (Redmine #6541)
- infer start-time of a process from elapsed when needed
(Redmine #4094)
- fix input range definition for laterthan() function (Redmine #6530)
- don't add trailing delimiter when join()'ing lists ending with a
null-value (Redmine #6552)
- 9999999999 (ten 9s) or higher has been historically used as an upper
bound in CFEngine code and policy but because of overflow on 32-bit
platforms it caused problems with big numbers. Fixed in two ways:
first change all existing policy uses to 999999999 (nine 9s instead
of eleven 9s), second fix the C code to not wrap-around in case of
overflow, but use the LONG_MAX value (Redmine #6531).
- cf-serverd and other daemons no longer reload their configuration
every minute if CFEngine is built with an inputs directory outside
of the work directory (not the default). (Redmine #6551)
3.6.1
New features:
- Introduced Solaris and AIX support into the 3.6 series, with many associated build and
bug fixes.
Changes:
- Short-circuit evaluation of classes promises if class is already set (Redmine #5241)
- fix to assume all non-specified return codes are failed in commands promises (Redmine #5986)
- cf-serverd logs reconfiguration message to NOTICE (was INFO) so that it's always logged in syslog
Bug fixes:
- File monitoring has been completely rewritten (changes attribute in files promise), which
eliminates many bugs, particularly regarding files that are deleted. Upgrading will keep
all monitoring data, but downgrading again will reinitialize the DB, so all files will be
reported as if they were new. (Redmine #2917)
- $(this.promiser) expands in files promises for 'transformer', 'edit_template',
'copy_from.source', 'file_select.exec_program', 'classes' and 'action' bodies
(Redmine #1554, #1496, #3530, #1563)
- 'body changes' notifies about disappeared files in file monitoring (Redmine #2917)
- Set not-kept classes when files or commands promise should be repaired, but is warn-only (Redmine #2359)
- Fixed CFEngine template producing a zero-sized file (Redmine #6088)
- Add 0-9 A-Z _ to allowed context of module protocol (Redmine #6063)
- Extend ps command column width on Solaris and filter on zone
rather than adding it to the ps output.
- Fixed strftime() function on Solaris when called with certain specifiers.
- Fixed users promise bug regarding password hashes in a NIS/NSS setup.
- Fixed $(sys.uptime), $(sys.systime) and $(sys.sysday) in AIX. (Redmine #5148, #5206)
- Fixed processes_select complaining about "Unacceptable model uncertainty examining processes" (Redmine #6337)
- ps command for linux has been changed to cope with big rss values (Redmine #6337)
- Address ps -axo shift on FreeBSD 10 and later (Redmine #5667)
- methods and services promises respect action_policy => "warn" (Redmine #5924)
- LMDB should no longer deadlock if an agent is killed on the hub while holding the DB lock.
Note that the change only affects binary packages shipped by CFEngine, since the upstream
LMDB project has not yet integrated the change. (Redmine #6013)
3.6.0
Changes:
- Changes to logging output
- add process name and pid in syslog message (GitHub #789)
- cf-serverd logging levels are now more standardised:
- INFO logs only failures
- VERBOSE logs successful requests as well
- DEBUG logs actual protocol traffic.
- cf-serverd now logs the relevant client IP address on
each message.
- Logging contexts to local database (cf_classes.tcdb) has been deprecated.
- 'usebundle' promisees are logged for all the bundle promises
- output from 'reports' promises has nothing prefixed except 'R: '
- a log line with stack path is generated when the promise type evaluated changes
- LMDB (symas.com/mdb) is the default database for local data storage : use version 0.9.9 or later
cf-agent --self-diagnostics (-x) is only implemented for TCDB, not for LMDB
- port argument in readtcp() and selectservers() may be a
service name (e.g. "http", "pop3").
- Enable source file in agent copy_from promises to be a relative path.
- file "changes" reporting now reports with log level "notice", instead of "error".
- process_results default to AND'ing of set attributes if not specified (Redmine #3224)
- interface is now canonified in sys.hardware_mac[interface] to align with
sys.ipv4[interface] (Redmine #3418)
- cf-promises no longer errors on missing bodies when run without --full-check (-c)
- Linux flavor "SUSE" now correctly spelled with all uppercase in variables and class names
(Redmine #3734). The "suse" lowercase version is also provided for convenience (Redmine #5417).
- $(this.promise_filename) and $(..._dirname) variables are now absolute paths. (Redmine #3839)
- including the same file multiple times in 'body control inputs' is not an error
- portnumber in body copy_from now supports service names like
"cfengine", "pop3" etc, check /etc/services for more.
- The failsafe.cf policy, run on bootstrap and in some other
unusual cases, has been extracted from C code into libpromises/failsafe.cf
- masterfiles
- cf_promises_validated is now in JSON format
- timestamp key is timestamp (sec since unix epoch) of last time validated
- the masterfiles now come from https://github.com/cfengine/masterfiles and are
not in the core repository
- cf-serverd calls cf-agent with -Dcfruncommand when executing cf-runagent requests
- Mark as removed: promise_notkept_log_include, promise_notkept_log_exclude, promise_repaired_log_include,
promise_repaired_log_exclude, classes_include, classes_exclude, variables_include,
variables_exclude attributes from report_data_select body (syntax is valid but not functional).
They have been replaced by the following attributes: promise_handle_include,
promise_handle_exclude, metatags_include, metatags_exclude.
New features:
- New promise type "users" for managing local user accounts.
- TLS authentication and fully encrypted network protocol.
Additions specific to the new type of connections:
- New attribute "allowlegacyconnects" in body server control,
which enables serving policy via non-latest cfengine protocol,
to the given list of hosts. If the option is absent, it
defaults to allow all hosts. To refuse non-TLS connections,
specify an empty list.
- New attribute "protocol_version" in body copy_from, and body
common control, which defines the preferred protocol for
outgoing connections.. Allowed values at the moment: "0" or
"undefined", "classic" or "1", "latest" or "2". By leaving the
copy_from option as undefined the common control option is
used, and if both are undefined then classic protocol is used
by default.
- The new networking protocol uses TLS for authentication,
after which all dialog is encrypted within the established
TLS session. cf-serverd is still able to speak the legacy
protocol with old agents.
- The 'skipverify' option in 'body server control' is
deprecated and only left for compatibility; it does
nothing
- cf-serverd does not hang up the connection if some request
fails, so that the client can add more requests.
- For the connections using the new protocol, all of the
paths in bundle server access_rules now differentiate
between a directory and a file using the trailing
slash. If the path exists then this is auto-detected and
trailing slash appended automatically. You have to append
a trailing slash manually to an inexistent or symbolic
path (e.g. "/path/to/$(connection.ip)/") to force
recursive access.
- New in 'access' promises for 'bundle server access_rules'
- Attributes "admit_ips", "admit_hostnames", "admit_keys",
"deny_ips", "deny_hostnames", "deny_keys"
- "admit_keys" and "deny_keys" add the new functionality
of controlling access according to host identity,
regardless of the connecting IP.
- For these new attributes, regular expressions
are not allowed, only CIDR notation for "admit/deny_ips", exact
"SHA=..." strings for "admit/deny_keys", and exact hostnames
(e.g. "cfengine.com") or subdomains (starting with dot,
e.g. ".cfengine.com") for "admit/deny"_hostnames. Same rules
apply to 'deny_*' attributes.
- These new constaints and the paths in access_rules, can contain
special variables "$(connection.ip)", "$(connection.hostname)",
"$(connection.key)", which are expanded dynamically for every
received connection.
- For connections using the new protocol, "admit" and "deny"
constraints in bundle server access_rules are being phased
out, preferred attributes are now "admit_ips", "deny_ips",
"admit_hostnames", "deny_hostnames", "admit_keys",
"deny_keys".
- New "shortcut" attribute in bundle server access_rules used to
dynamically expand non-absolute request paths.
- masterfiles
- standard library split: lib/3.5 (compatibility) and lib/3.6 (mainline)
- many standard library bundles and bodies, especially packages- and file-related,
were revised and fixed

- file-related: file_mustache, file_mustache_jsonstring, file_tidy, dir_sync, file_copy,
file_link, file_hardlink, file_empty, file_make
- packages-related: package_absent, package_present, package_latest,
package_specific_present, package_specific_absent, package_specific_latest, package_specific
- XML-related: xml_insert_tree_nopath, xml_insert_tree, xml_set_value, xml_set_attribute
- VCS-related: git_init, git_add, git_checkout, git_checkout_new_branch,

Bug fixes: for a complete list of fixed bugs, see Redmine at https://cfengine.com/dev
- various fixes in evaluation and variable resolution
- Improve performance of list iteration (Redmine #1875)
- Removed limitation of input length to internal buffer sizes
- directories ending with "/" are not ignored
- lsdir() always return a list now, never a scalar

3.5.3
Changes:
- Improved security checks of symlink ownership. A symlink created by a user pointing
to resources owned by a different user will no longer be followed.
- Changed the way package versions are compared in package promises. (Redmine #3314)
In previous versions the comparison was inconsistent. This has been fixed, but may
also lead to behavior changes in certain cases. In CFEngine 3.5.3, the comparison
works as follows:
<package-being-considered> <package_select> <package_version>
For instance:
apache-2.2.31 ">=" "2.2.0"
will result in the package being installed.
Bug fixes:
- fix cf-monitord crash due to incorrect array initialization (Redmine #3180)

3.5.1
Changes:
- file changes are logged with log level Notice, not Error
- the CFEngine Standard Library in masterfiles/libraries is now split into
promise-type specific policy files, and lives in a version-specific directory.
This should have no impact on current code, but allows more granular include of
needed stdlib elements (Redmine #3044)

- every
- none
- some
- nth
- sublist
- uniq
- filter
- classesmatching
- strftime
- filestat
- ifelse
- maparray
- format
- cf-promises flag --parse-tree is replaced by --policy-output-format=, requiring the
user to specify the output format (none, cf, json)
- cf-promises allows partial check of policy (without body common control) without integrity check;
--full-check enforces integrity check
- agent binaries support JSON input format (.json file as generated by cf-promises)
- cf-key: new options --trust-key/-t and --print-digest/-p
- Class "failsafe_fallback" is defined in failsafe.cf when main policy contains errors and
failsafe is run because of this
- add scope attribute for body classes (Redmine #2013)
- Better diagnostics of parsing errors
- Error messages from parser now show the context of error
- new cf-agent option: --self-diagnostics
- new output format, and --legacy-output
- warnings for cf-promises.

- Make parser output in GCC compatible format the only supported format
(remove --gcc-brief-format flag)
- Silence license warnings in Enterprise Free25 installations
- action_policy => "warn" causes not_kept classes to be set on promise needing repair.
- command line option version (-V) now prints a shorter parsable version without graphic
- implicit execution of server and common bundles taking arguments is skipped in cf-serverd.
- WARNING: option --policy-server removed, require option to --bootstrap instead
- process promises don't log if processes are out of range unless you
run in verbose mode
- reports promises are now allowed in any context (Redmine #2005)
- cf-report has been removed
- cf-execd: --once implies --no-fork
- Version info removed from mail subject in the emails sent by cf-execd.
The subject will only contain "[fqname/ipaddress]" instead of "communnity/nova [fqname/ipaddress]"
Please change your email filters accordingly if necessary.
- "outputs" promise type is retired. Their semantics was not clear, and the functionality
is better suited for control body setting, not a promise.
- Tokyo Cabinet databases are now automatically checked for
correctness during opening. It should prevent a number of issues
with corrupted TC databases causing binaries to hang.
- Improved ACL handling on Windows, which led to some syntax changes. We now consistently
use the term "default" to describe ACLs that can be inherited by child objects. These
keywords have received new names:
acl_directory_inherit -> acl_default
specify_inherit_aces -> specify_default_aces
The old keywords are deprecated, but still valid. In addition, a new keyword
"acl_inherit" controls inheritance behavior on Windows. This feature does not exist on
Unix platforms. (Redmine #1832)
- Networking code is moved from libpromises to its own library,
libcfnet. Work has begun on making the API more sane and thread-safe.
Lots of legacy code was removed.
- Add getaddrinfo() replacement in libcompat (borrowed from PostgreSQL).
- Replace old deprecated and non thread-safe resolver calls with
getaddrinfo() and getnameinfo().
- Hostname2IPString(), IPString2Hostname() are now thread-safe, and are
returning error when resolution fails.
- Running cf-execd --once now implies --no-fork, and also does not wait
for splaytime to pass.
- execresult(), returnszero() and commands promises no longer requires the first word
word to be an absolute path when using the shell. (Part of Redmine #2143)
- commands promises useshell attribute now accepts "noshell" and "useshell" values. Boolean
values are accepted but deprecated. (Part of Redmine #2143)
- returnszero() now correctly sets the class name in this scenario (Part of
Redmine #2143):
classes:
"commandfailed" not => returnszero("/bin/nosuchcommand", "noshell");
Bugfixes:

- silence type-pun warning when building on HP-UX (GitHub #287)
3.4.1 (Bugfix and Stability release)
New feature/behavior:
- cf-execd terminates agent processes that are not responsive
for a configurable amount of time (see agent_expireafter in body
executor control), defaulting to 1 week

3.4.0
New features:
- Added rpmvercmp utility to compare versions of RPM packages for
accurate sorting of RPM packages for packages promises.
- Implement network timeout on server side to avoid keeping stale
connections for hours.
- XML editing capabilities. See the documentation for edit_xml
body. Note the new dependency: libxml2.
- Implement inheritance of local classes by bundles called using
"usebundle". By default classes are not inherited. See the
examples/unit_inherit.cf for an example.
- Moved from Nova/Enterprise:
- POSIX ACL support,
- "outputs" promise type,
- remote syslog support.
- packages_default_arch_command hook in packages promises, to
specify default architecture of the packages on the system.
- packages_version_less_command / packages_version_equal_command hooks
in packages promises, to specify external command for native package
manager versions comparison
- agent_expireafter in body executor control allows you to set a
timeout on all cf-agent runs, to enforce a threshold on the
number of concurrent agents
- Running in Solaris zone is now detected and classes "zone" and
"zone_<name>" are created in this case.
- VirtualBox support added to guest_environment promises.
- guest_environment promises are supported under OS X.
- The "depends_on" attribute is now active, for the partal ordering
of promises. If a promise depends on another (referred by handle)
it will only be considered if the depends_on list is either kept
or repaired already.
** WARNING: When upgrading, make sure that any existing use
of depends_on does not make some promises being
unintentionally ignored. This can happen if you are
currently refering to non-existant or never-run handles
in depends_on attributes.
- methods return values, initial implementation
- New format for cf-key -s, includes timestamp of last connection
- cf-promises --parse-tree option to parse policy file and dump it
in JSON format
- Namespaces support for bundles and bodies. See the
examples/unit_namespace*.cf for the usage.
- Default arguments for bundles. See the examples/unit_defaults.cf
- Metadata promise type. See the examples/unit_meta.cf
New semantics:
- Methods promises now return the status of promises
kept within them. If any promise was not kept, the method is not
kept, else if any promise is repaired, the method was repaired
else it was kept.
- Remote variable access in namespaces by $(namespace:bundle.variable)
Changed functionality:
- cf-execd -F switch no longer implies 'run once'. New -O/--once
option is added to achieve this behaviour. This makes cf-execd
easier to run from systemd, launchd and other supervision
systems.
Misc:
- Support for the following outdated platforms and corresponding
classes has been removed. De facto those platforms were
unsupported for a long time, as CFEngine codebase uses C99
language features unavailable on old platforms:
- SunOS 3.x (sun3)
- SunOS 4.x (sun4)
- Ultrix (ultrix)
- DEC OSF/1 AXP (osf)
- Digital UNIX (digital)
- Sony NEWS (newsos)
- 4.3BSD (bsd4_3)
- IRIX (irix, irix4, irix64)
- IBM Academic Operating System (aos)
- BSD/OS / BSDi / BSD/386 (bsdos)
- NeXTSTEP (nextstep)
- GNU Hurd (gnu)
- NEC UX/4800 (ux4800)
- (Old news) Since 3.3.0 the layout of CFEngine Community packages
has changed slightly.
cf-* binaries have been moved to /var/cfengine/bin, due to the
following reasons:
- cf-* binaries are linked to libraries installed to
/var/cfengine/lib, so placing binaries in /usr/local/sbin does not
increase reliability of the CFEngine,
- keeping whole CFEngine under single prefix (/var/cfengine)
makes packaging simpler,
- it matches the layout of CFEngine Enterprise packages.
Please adjust your policies (the recommended ways to deal with
the move are either to adjust $PATH to include /var/cfengine or to
create symlinks in /usr/local/sbin in case you are relying on
binaries to be available in $PATH).
- Workdir location is properly changed if --prefix or --enable-fhs
options are supplied to configure (Mantis #1195).
- Added check for broken libmysqlclient implementations (Mantis #1217).
- Standard library is updated from COPBL repository.
- cf-know is no longer built in Community releases. The only
functionality useful in Community, namely the reference manual
generation, is provided by new compile-time cf-gendoc tool.
- Filename (for storing filechanges) changed
from file_change.log -> file_changes.log (in /var/cfengine/state)
New format for storing file changes introduced:
[timestamp,filename,<N/C/S/R>,Message]
N = New file found
C = Content Changed
S = Stats changed
R = File removed
- Acceptance test suite passes on Mac OS X.
- Changed some port numbers to replace old services with imap(s)
- archlinux hard class on Arch Linux.
- Detect BSD Make and automatically switch to GNU Make during build.
Bugfixes:
- cfruncommand for cf-execd is an arbitrary shell command now (Mantis #1268).
- Fixed broken "daily" splayclasses (Mantis #1307).

Versions 3.3.6, 3.3.7 were internal and weren't released.
Bugfixes:
- Propery set sys.domain variable if hostname is fully-qualified.
- Fixed several small memory leaks.
- Make network timeout for network reads configurable. Previously
it was hardcoded to be 30 seconds, which was not enough for

Misc:
- Fix memory leak during re-read of network interfaces'
information in cf-execd/cf-serverd.
3.3.3 (Bugfix and Stability release)
Evaluation of policies:
- Zero-length files are valid for readfile() and similar functions
(Mantis #1136).
- Unchoke agent in case it encounters symlinks in form ./foo
(Similar to Mantis #1117).
Misc:
- Fix generation of reference manual on machines with umask more
relaxed than 022.
- Use statvfs(3) on OpenBSD to obtain filesystem information
(Mantis #1135).
3.3.2 (Bugfix and Stability release)
Evaluation of policies:
- Do not segfault if file copy was interrupted due to network
connectivity or server going away (Mantis #1089).
- Do not segfault if log_failed attribute is present in body, but
log_kept is not (Mantis #1107).
- Do not mangle relative paths in symlinks during file copy
Previously symlink a -> b was mangled to a -> ./b.
(Mantis #1117)
- Properly compare 1.0 and 1.0.1 in packages promises. Previously
only versions with equal amount of "segments" were comparable
(Mantis #890, #1066).
Base policy:
- Properly set permissions on files for /var/cfengine/lib on HP-UX
(Mantis #1114).
- Standard library (cfengine_stdlib.cf) is synced with COPBL
repository.
Misc:
- Do not create huge file in case corrupted TokyoCabinet database
is detected (Mantis #1106).
- Fix file descriptor leak on error paths, may have caused crashes
of cf-execd and cf-serverd (Issue #1096).
- Fix intermittent segfault in cf-execd (Mantis #1116).
- Impose an upper limit on amount of listening sockets reported by
cf-monitord. Huge amounts of listening sockets caused cf-agent to
segfault on next run (Mantis #1098).
- Add missing function prototypes caused errors during compilation
on HP-UX (Mantis #1109).
- Fix compilation on Solaris 11 (Mantis #1091).
3.3.1 (Bugfix and Stability release)
Evaluation of policies:
- Do not cut off name of bundle in variables interpolation (Mantis #975).
- Do not segfault in function evaluation guarded by ifvaclass clause (Mantis #1084, #864).
- Do not segfault if "classes" promise does not declare any value to be evaluated (Mantis #1074).
- Do not segfault in database promises if there is no
database_operation provided (Mantis #1046).
Built-in functions:
- Fix countclassesmatching() function which was misbehaving trying
to match classes starting with alphanumeric symbol (Mantis #1073).
- Fix diskfree() to return kilobytes, as described in documentation (Mantis #980, #955).
- Fix hostsseen() function to avoid treating all hosts as not
being seen since 1970 (Mantis #886).
- Do not output misleading error message if readtcp() is unable to connect (Mantis #1085).
Command-line interface:
- -d option previously reqired an argument, though help message disagreed (Mantis #1053).
- Disable --parse-tree option, not ready for the release (Mantis #1063).
- Acept -h as a --help option.
- Ensure that cf-execd might be started right after being shut down.
Misc:
- Plug file descriptor leak after failed file copy (Mantis #990).
- Fix unsafe admit rules in default promises.cf (Mantis #1040).
- Fix splaytime to match documentation: it is specified in minutes, not seconds (Mantis #1099).
Packaging:
- Fix owner/group of initscript and profile.d snippet in RPM builds (Mantis #1061, #1058).
- Fix location of libvirt socket CFEngine uses to connect to libvirtd (Mantis #1072).
- Install CoreBase to /var/cfengine/masterfiles during installation (Mantis #1075).
- Do not leave old cf-twin around after upgrade (Mantis #1068)
- Do not leave rcS.d symlinks after purging .deb package (Mantis #1092).
3.3.0
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_<mac_address>:: - 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

Help text of cf-report -r corrected - a list of key hashes is
required, not ip addresses.
New Emacs mode for CFEngine policy files (thanks to Ted Zlatanov!)
