Released 14 July 2020 and shipped with Puppet Platform 5.5.21.
facter -pcommand returns NUL character on stdout when called from nested Ruby on Windows. This release fixes an issue where Facter executed a system command using back ticks when called from Ruby. FACT-2682
Released 30 April 2020 and shipped with Puppet Platform 5.5.20.
This release moves
cached-custom-factsto a new section in the
This release allows you to cache custom facts based on the
facter.conffile. Depending on the
Facts.ttls, custom facts defined in
Facts.cached-custom-factswill be cached. FACT-1575
Previously, when the
oslevel -scommand was executed on AIX, redirects
/dev/nullwere shown on
kernelfact broke. This is now fixed. FACT-2545
Previously, when os-specific facts were not resolved, Puppet logged a warning. This release lowers the severity of the logged messages to debug. FACT-2489
Released 10 March 2020 and shipped with Puppet Platform 5.5.19
Released 14 January 2020
This release adds support for the
fips_enabledfact on Windows. The check examines the contents of
HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/Lsa/FipsAlgorithmPolicy/Enabled. If the returned value is 1, it means that FIPS mode is enabled. FACT-2065
Facter can now return the new
scope6fact to display IPv6 address scope. FACT-2016
Facter command execution now accepts a Boolean parameter,
expand. By default, Facter searches the command and expands it to absolute path. When
expandis set to false, Facter verifies whether the command is a shell command and, if so, passes the command as is.FACT-1824
Facter incorrectly reported disabled CPU cores as physical CPU cores. Now, Facter correctly reports physical and logical CPUs and ignores disabled CPUs. FACT-1824
In previous releases, Facter did not report the
cloudfact on Azure. This issue is now fixed. FACT-2004
In previous versions, Facter could not always determine the primary network interface on Solaris, so it sometimes failed to return any valid interface. This is now fixed. FACT-2146
-In systems using Windows Remote Desktop Services (RDS), Facter returned an incorrect operating system fact. This was due to a Windows API deprecation that caused issues in mixed 32- and 64-bit application environments, such as RDS. FACT-2096
Released 15 October 2019 with Puppet 5.5.17.
Google Compute Engine's internal metadata service is deprecating the v1beta1 endpoint sometime before the end of 2019. To prepare for this, Facter now uses the v1 endpoint instead. FACT-2018
When Facter starts a mountpoint to get the size and available space, it automatically mounts type
autofsmountpoints, which is not the intended behavior. Automounts are now skipped by Facter when resolving mountpoints. FACT-1992
Released 16 July 2019 with Puppet 5.5.16.
This release adds new facts for Windows 10/2016+ :
ReleaseID: The 4 digit Windows build Version in the form
InstallationType: Differentiates Server, Server Core, Client (Desktop):
EditionID: Server or Desktop Edition variant:
ProductName: Textual Product Name.
Exception: on Windows 10 1511-x86_64,
ReleaseID is not displayed, as is not
present in Windows registry.
This release fixes an issue with Facter gem installation errors, which occurred because Facter was pinned to Ruby 2.1.7. The pinned version is now 2.1. FACT-1918
Prior to this release, Facter returned warnings if
ip route showoutput was not in a key-value format. However, this format does not apply to all configurations, and Facter no longer returns warnings about this. FACT-1916
mountpointfact showed only temporary file systems and physical mounts. Now Facter returns mount points for all mounts on the systems. FACT-1910
This release adds support for Virtuzzo Linux facts. FACT-1888
Released 16 April 2019
Previously, Facter incorrectly reported operating system facts (such as
os.release) on Ubuntu systems that did not have the
lsb_releaseexecutable. Operating system facts are now resolved without relying on
Released 15 January 2019
This is a bug-fix release that shipped with Puppet Platform 5.5.10
Facter now correctly returns the path to system32 on 64-bit systems when a user has manually created the "sysnative" folder. FACT-1900
Released 1 November 2018
This is a bug-fix release that shipped with Puppet Platform 5.5.8
Previously, if you had multiple custom versions of a built-in fact, and only those with a weight of 0 could resolve, Facter used those zero-weighted values. Now, if only zero-weighted custom facts resolve, Facter uses built-in fact values instead. (FACT-1873)
Released 23 October 2018
This is a bug-fix release that shipped with Puppet Platform 5.5.7.
Facter now correctly distinguishes between Windows Server 2016 and Windows Server 2019. (FACT-1889)
Released 21 August 2018
This is a bug-fix release that shipped with Puppet Platform 5.5.6.
Facter now indicates if SELinux is enabled on the system by also checking for the existence of the
/etc/selinux/configfile in addition to checking for the presence of the SELinux file system. (FACT-1477)
Facter returned the wrong IPv6 information when IPV6 stack was disabled. Now,Facter correctly validates the IP command's output for the IPv6 family. If the IP command's output is invalid (for example, if it contains IPv4 info), then Facter ignores it. (FACT-1475)
Facter failed on Solaris 11.3 patch 126.96.36.199 native zone. Now, Facter does not try to read kstat entries that it does not need to process. This avoids potential permissions issues when run in a zone or as non-root on Solaris. (FACT-1832)
Facter has been updated to correctly read the format of
/etc/system-releaseunder Amazon Linux 2. This corrects the operating system release fact, which previously fell back to the kernel version. (FACT-1865)
os.architecturefact is now determined from the
processors.modelsfact. This addresses a problem where Puppet agent wasn't working with dynamic CPU allocations on AIX. (FACT-1550)
memoryfact was occasionally failing on AIX. This has been fixed. (FACT-1821)
Released July 17, 2018.
This is a bug-fix release that shipped with Puppet Platform 5.5.4.
Facter 3.11.3 correctly reads the format of
/etc/system-releaseand reports the
os releasefact on Amazon Linux 2. Previous versions of Facter instead fell back to the kernel version. (FACT-1865)
Facter 3.11.3 no longer tries to read
kstatentries that it does not need to process. This avoids potential permissions issues when run in a zone or as non-root on Solaris. (FACT-1832)
Released June 7, 2018.
This is a bug-fix release that shipped with Puppet Platform 5.5.2 and 5.5.3.
When using the
systemd-networkdDHCP client, previous versions of the Linux networking resolver didn't know how to collect DHCP lease information, since it expected
dhclientto be installed. Systems relying entirely on
systemd-networkdfor DHCP management do not use
Facter 3.11.2 checks
systemd-networkd's DHCP leases directory (
/run/systemd/netif/leases) in addition to
dhclient's lease files when attempting to identify DHCP servers.
Released April 17, 2018.
This is a bug-fix and feature release that shipped with Puppet Platform 5.5.1.
Released March 20, 2018.
This is a bug-fix and feature release that shipped with Puppet Platform 5.5.0.
uptimefact for Windows now uses
GetTickCount64, which is more reliable, minimizes clock skews, and offers better resolution than the previous method of computing using WMI BootUptime.
For each SSH key, Facter 3.11.0 includes the key type as part of its
