3.6.2

Bug fixes:
- don't regenerate software_packages.csv every time
- improve verbose message for package_list_command
- fix missing log output on AIX
- assorted fixes to dirname() esp on Windows
- fix package manager detection
- fix build issues on FreeBSD
- allow copying of dead symbolic links

  null-value
- 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
- 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).

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
 - fix to assume all non-specified return codes are failed in commands
  promises
- 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.
 - $(this.promiser) expands in files promises for 'transformer',
  'edit_template', 'copy_from.source', 'file_select.exec_program', 'classes'
  and 'action' bodies
- 'body changes' notifies about disappeared files in file monitoring
- Set not-kept classes when files or commands promise should be repaired,
  but is warn-only
- Fixed CFEngine template producing a zero-sized file
- Add 0-9 A-Z _ to allowed context of module protocol
- 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.
  #5148, #5206)
- Fixed processes_select complaining about "Unacceptable model uncertainty
  examining processes"
- ps command for linux has been changed to cope with big rss values
- Address ps -axo shift on FreeBSD 10 and later
- methods and services promises respect action_policy => "warn"
 - 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.

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
 - interface is now canonified in sys.hardware_mac[interface] to align with
  sys.ipv4[interface]
- 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. The "suse" lowercase version is also
  provided for convenience.
- $(this.promise_filename) and $(..._dirname) variables are now absolute
  paths.
- 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/$(connection.ip)/") to force
      recursive access.
- New in 'access' promises for 'bundle server access_rules'
    - Attributes "admit_ips", "admit_hostnames", "admit_keys",
      "deny_ips", "deny_hostnames", "deny_keys"
    - "admit_keys" and "deny_keys" add the new functionality
      of controlling access according to host identity,
      regardless of the connecting IP.
    - For these new attributes, regular expressions
      are not allowed, only CIDR notation for "admit/deny_ips", exact
      "SHA=..." strings for "admit/deny_keys", and exact hostnames
      (e.g. "cfengine.com") or subdomains (starting with dot,
      e.g. ".cfengine.com") for "admit/deny"_hostnames. Same rules
      apply to 'deny_*' attributes.
    - These new constraints and the paths in access_rules, can contain
      special variables "$(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
        - supports both Community and Enterprise
        - new 'inventory/' structure to provide OS, dmidecode, LSB, etc.
          system inventory (configured mainly in def.cf)
        - cf_promises_release_id contains the policy release ID which is
          the GIT HEAD SHA if available or hash of tree
        - a bunch'o'bundles to make starting with CFEngine easier:
        - 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, git_clean, git_stash, git_stash_and_clean,
          git_commit, git
        - process-related: process_kill
        - other: cmerge, url_ping, logrotate, prunedir
- New command line options for agent binaries
    - New options to cf-promises
        - '--show-classes' and '--show-vars'
        - '--eval-functions' controls whether cf-promises should evaluate
          functions
    - Colorized output for agent binaries with command line option '--color'
      (auto-enabled if you set CFENGINE_COLOR=1)

        - pass a data container to a bundle with the @(container) notation
        - the module protocol accepts JSON for data containers with
          the '%' sigil
    - Tagging of classes and variables allows annotating of language
      construct with meta data; supporting functionality:
        - The module protocol in 'commands' promises has been extended
          to allow setting of tags of created variables and classes,
          and the context of created variables

  compliance

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

Bug fixes:

3.5.0

New features:
- classes promises now take an optional scope constraint.
- new built-in functions: every, none, some, nth, sublist, uniq, filter
  - 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
- 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.
- Enable zeroconf-discovery of policy hubs for automatic bootstrapping
  if Avahi is present
- Support for sys.cpus on more platforms than Linux & HPUX

Changes:
- parser no longer allows ',' after promiser or promisee. must be either
  ';' or lval
- 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
- 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.
- 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.
- commands promises useshell attribute now accepts "noshell" and "useshell"
  values. Boolean values are accepted but deprecated.
- returnszero() now correctly sets the class name in this scenario:
      "commandfailed" not => returnszero("/bin/nosuchcommand", "noshell");

Bugfixes:
- bundles are allowed to be empty
- Fixed '.' and '-' not being accepted by a commands module.
- Correct parsing of list variables by a command module.
- Fixed issue with package management and warn.
- Fixed JSON crash.
- Improved error checking when using fgets().
- Fixed error message when deleting nonexistent files.
- Honor warn-only when purging from local directory.
- Make sure "restart" and "reload" are recognized keywords in packages.
- Allocate memory dynamically to avoid out-of-buffer or out-of-hash
  situations
- fix edit_xml update of existing attributes
- use failsafe policy from compile-time specified workdir
- ifvarclass checked from classes promises in common bundles
- do not wait for splaytime when executing only once
- disable xml editing functionality when libxml2 doesn't provide necessary APIs
- Out-of-tree builds should work again, fixed a bunch of related bugs.
- Fixed race condition in file editing.
- Fixed memory leak in cf-serverd and others
