QA Farm rebuild - #2701
Conversation
Specifically ... - symlinks are still symlinks - directories are present and don't contain files not in the tarball - files are present with correct size and modes And then exceptions for all the ones we expect to be different after some QA churn. Most useful for finding old files that used to be in the tarball but are no longer packaged ... these should be included in the ./postinstall cleanup script.
Extend the "cull" list of files and directories from old versions of the tarball packaging to better match the current reality ... driven by the (new) verify-install script on vm06 (FreeBSD 14.4).
Previous regime was packaging .out files for :retired scripts but no the test scripts themselves. With this change neither are packaged for :retired or :reserved tests. Get rid of all references to qa_outfiles and replace the makefile one-liner with a (new) ./list-outfiles script. Explicitly add some "other" files that are needed but are not .out files (these were being packaged by accident in the past).
The mmv PMDA should be present always, but if it is not running these tests die in horrible ways rather than _notrun ... add guards.
For Fedora+44+x86_64 and Ubuntu+26.04+x86_64.
Once the kvm stuff is done and the base system installed and running and ssh keys setup, this script will do all of the heavy lifting - checking sudo is working - getting awk and git installed - setting up networking - enable getty for the virsh console - cloning the pcp git tree - check packing-list exists for platform and install missing packages needed for pcp build and qa - running configure in the pcp tree (qa/admin/myconfigure -q) - running a stripped down version of qa/admin/check-vm Only tested for Debian so far ... I'll add more package managers as I rebuild the QA Farm.
From the QA Farm rebuild - openSUSE updates for Leap and Tumbleweed (i686) - Debian 13 updates - fix configure.ac to correctly identify SUSE (Leap) and SUSE Tumbleweed distros - next round of surgery for post-setup
From the QA Farm rebuild - pcp.spec needs Provides...user() and Provides...group() for SUSE at Leap 16 *or later* (Tumbleweed is later) - add perl-Archive-Zip to manifest for rpm platforms and add it to the package-lists for Tumbleweed
Don't build or package the postfix PMDA if Perl is not available ... in practice this most likely means a 32-bit platform where Perl is not Y2038-safe, like, er, SUSE Tumbleweed i586.
From the QA Farm rebuild for CentOS 7, 8, 9 and 10.
In the QA Farm vm36 runs a dedicated, isolated and unrestricted Xorg server on seat :1 ... just for remote systems running QA.
These two need to share the same logic for the way they run configure across all platforms. [probably needs a refactor to make this stuff exist in only one place]
From the QA Farm rebuild for Arch Linux and Ubuntu 18.04, 20.04 22.04, 24.04 and 26.04.
From the QA Farm rebuild for RHEL 9 and 10, and OpenBSD 7.7.
Another fallout from rebuilding the QA Farm ... ld(1) on vm27 (64-bit OpenBSD 7.8) emits a phantom _mode.rel symbol which breaks check-statics for both libpcp.so.4 and libpcp.so.3.
From the QA Farm rebuild for NetBSD 7.7.
- qa/admin/list-packages
+ make fmt(1) use platform-neutral
+ skip "base .* install" "packages" from manifest (with -c) as
these are not real package names
+ add missing pkgin parts of the recipes
+ fix some logic errors on error paths
- qa/admin/other-packages/manifest
+ add/repair lots of pkgin lines
+ bulk whitespace changes to make the file easier to read, edit
and grep for
- qa/admin/other-packages/require
+ updates for NetBSD
+ qa/admin/post-setup
+ refactor to clean things up
+ add NetBSD bits-n-pieces
From the QA Farm rebuild for NetBSD 10.1, NetBSD 11.0 and OpenBSD 7.9. Also fixes for qa/admin/old-list-packages so "new" works better in qa/admin/package-lists.
From the QA Farm rebuild for Fedora Rawhide (currently F46).
Various of our "postinst" scripts were blindly assuming that if systemd helpers like systemd-tmpfiles or systemd-sysusers were installed than systemd was running ... on MX Linux, out of the box, these helpers are present but systemd is not active. Add a [ "`ps -p 1 -o comm=`" = systemd ] guard to check if systemd is really doing init's job.
From the QA Farm rebuild for AmazonLinux 2023, Fedora 44, LinuxMint 25.2 and MX Linux 25.2 - new or updated packing-list files - tweaks for qa/admin/other-packages/manifest - effectively retire qa/admin/other-packages/require as this is no longer adding any value - qa/admin/post-setup needed more bells and whistles - qa/README.vm updates - fix qa/admin/old-list-packages so that qa/admin/packing-lists/new works better - qa/admin/list-packages - add a -u flag to run -c _and_ update the packing list for the things that can be unilaterally added or dropped - qa/admin/pcp-daily needs to know about some more special VMs and hosts - new qa/008.out.bozo for the born again bozo - qa/qa_hosts.primary update QA Farm "special" hosts - qa/check.callback.sample update QA Farm "special" hosts - qa/common.check fix a typo in _all_ipaddrs() for network interface names vibr should have been virbr and ditto for _all_hostnames()
…and double values After bozo was rebuilt, the new faster CPU (AMD this time, not Intel as well) mean that the lmsensors PMDA was exporting values for PM_TYPE_FLOAT metrics like lmsensors.amdgpu_pci_7600.sclk in the 600000000 range, but t.his is big enough to flip libc so that %x.8g produces a value of 6e+8 (scientific notation, ot fixed format) which blows up qa/1480 when it asks awk to do arithmetic on this value which is no longer numeric in awkland. This is really symptomatic of an arbitrary decision in libpcp (8) that the user cannot change. pmPrintValue() is sufficently low-level that the problem is visible in pminfo, pmprobe, pmrep, ... So I've introduced another environment variable, $PCP_FLOAT_PRECISION that can be used to set the precision for float value printing to be something other than 8. And the same problem exists and is fixed the same way for PM_TYPE_DOUBLE where the (new) $PCP_DOUBLE_PRECISION allows something different to the hard-coded 16 digits of precision.

In `@build/tar/verify-install`:
- Line 38: Update the verification script’s EXIT trap to preserve the actual
failure status instead of unconditionally exiting 0, and track detected
installation mismatches so any mismatch exits nonzero while successful
verification remains zero.
- Around line 145-146: Update the metadata parsing pipeline in verify-install so
it does not assume BSD-specific tar field positions; read the archive size from
a stable field or explicitly handle GNU tar and BSD tar formats, while
preserving the permission, size, and file values consumed by the read loop.
In `@qa/1480`:
- Line 100: Remove the fixed /tmp/eek output from the tee invocation in the QA
script, and preserve the pipeline’s intended output without creating a shared
unmanaged temporary file. Use the existing QA working-directory cleanup or an
appropriate unique temporary-output mechanism if tee still requires a file.
In `@qa/admin/list-packages`:
- Around line 737-744: Update the package-list update flow around $tmp.add and
$tmp.new to append each queued addition uniquely into $tmp.new before the diff
and copy operations. Preserve the existing verbose reporting, and ensure both
missing manifest packages and one copy of deduplicated entries are retained.
In `@qa/admin/other-packages/manifest`:
- Line 1454: Correct the swrast_dri.so path in the pkgin QA manifest entry by
replacing the misspelled “modudes” directory with “modules”, preserving the
existing wildcard and package-check behavior.
- Around line 1339-1344: Update the valkeysearch.so entries in the package
manifest to use the applicable absolute installed module path instead of bare
filenames, so qa/admin/check-manifest validates the shared module rather than
searching PATH; preserve each package manager’s existing applicability and
status annotations.
In `@qa/admin/package-lists/MX`+25.2+x86_64:
- Around line 1-2: Synchronize package-list headers with their represented
platforms: in qa/admin/package-lists/MX+25.2+x86_64 lines 1-2, change MX 23.2 to
MX 25.2 and replace the stale 2024 creation date with the current source date;

FreeBSD 14.4; in qa/admin/package-lists/OpenBSD+7.7+amd64 lines 29-42, change
OpenBSD 7.4 to OpenBSD 7.7.
In `@qa/admin/package-lists/NetBSD`+11.0+amd64:
- Around line 1-2: Rename the NetBSD amd64 package manifest from the 11.0
variant to the 11.1 variant, and update its header comment to identify NetBSD
11.1 amd64 so qa/admin/list-packages can select it for that VM release.
In `@qa/admin/post-setup`:
- Around line 33-38: In the post-setup refresh logic, rename the misspelled
refesh setting to refresh and move the use_rsync detection currently assigned
later so it executes before the self-refresh block. Ensure the refresh branch
tests the initialized use_rsync value, and preserve the fallback to scp when
rsync is unavailable without relying on the unset SCP_PORT variable.
- Around line 19-21: Update the post-setup script’s status handling around the
final check-vm call: capture and propagate check-vm’s result, setting sts to 0
when that check succeeds while preserving nonzero failures for the trap’s exit.
- Around line 268-277: Update the error message in the _ttys backup block to
reference the failed /etc/ttys operation, and remove the out-of-scope $iface
reference.
- Line 944: Remove the debug artifact command cp $tmp.tmp /tmp/eek from the
post-setup script, leaving the surrounding temporary-file handling unchanged.
- Around line 663-691: Update the sudo cp operation in the /etc/mygate update
branch to copy the file created at $tmp.gateway, not the nonexistent
$tmp.mygate; preserve the existing success marker and failure handling.
- Around line 799-802: Update the sed expressions in the systemd-resolved
configuration edit so nameserver and domain variables expand before sed runs;
use double-quoted expressions while preserving the existing replacement patterns
and output behavior.
- Around line 702-704: In the BSD network-selection conditional, update the test
from the undefined isnet_bsd variable to the existing is_netbsd variable so only
NetBSD hosts enter this branch, and correct the adjacent comment from
“MetBSD-style” to “NetBSD-style”.
In `@qa/GNUmakefile`:
- Line 50: Ensure failures from list-outfiles stop the build instead of allowing
a partial output list to continue to install. Add a phony validation
prerequisite that explicitly runs and validates list-outfiles, and include it in
the default, default_pcp, install, and install_pcp targets while preserving
their existing prerequisites.
In `@qa/README.vm`:
- Line 29: Update the documentation in README.vm to correct “crediential” to
“credential,” “Tubleweed” to “Tumbleweed,” and add the missing comma in the
FreeBSD release list.
- Line 535: Replace the pkgin update command in the package-update recipe with
sudo pkg_add -u so the documented command upgrades all installed OpenBSD
packages.
In `@src/libpcp/src/util.c`:
- Around line 1026-1029: Update pmPrintValue’s PCP_FLOAT_PRECISION and
PCP_DOUBLE_PRECISION handling to parse values with strtol instead of atoi,
requiring complete integer input and rejecting errno failures, negative, zero,
and out-of-range values; preserve the documented defaults whenever validation
fails. Add tests covering unset, valid, malformed, negative, zero, and oversized
environment values.

GNU tar -tvzf verbose listing output field order size timestamp documentation
💡 Result:
When using the --verbose (-v) option with GNU tar, the command produces a detailed, ls -l-style listing [1][2]. The output consists of exactly six fields for each archive member, appearing in the following order [3][1][4]: 1. File type and permissions: Displayed in symbolic form (e.g., -rw-r--r--), identical to the first column of the output from ls -l [3][1]. 2. Owner/Group: The owner name and group name, separated by a slash (e.g., user/group). If this information is unavailable, such as in older 'v7' format archives, numeric ID values are displayed instead [3][1][4]. 3. Size: The file size in bytes [3][1]. 4. Modification date: The date of last modification, formatted in ISO 8601 (e.g., YYYY-MM-DD) [3][1]. 5. Modification time: The time of last modification (e.g., HH:MM) [3][1]. 6. File name: The name of the file or archive member. Special characters (such as newlines or whitespace) are displayed using quoting styles to remain unambiguous [3][1]. Depending on the file type, additional information may follow the name (e.g., "-> link-name" for symbolic links) [3][1][5]. Note that when creating or updating an archive, the verbose output is sent to standard error, whereas it is sent to standard output when listing an archive [6]. Additionally, the file names displayed during a verbose listing may differ from those seen when creating the archive, as GNU tar may strip leading directory prefixes by default [2][7].

Do not parse tar metadata with BSD-specific field positions.
build/tar/verify-install reads $5 as the archive size. GNU tar places the size in $3 and the modification time in $5, so GNU/Linux checks can report false size mismatches. Use stable metadata fields or support each tar format explicitly.

As a result, -u deletes duplicate entries but does not restore one copy. It also does not add packages that the manifest identifies as missing.
Append unique entries from $tmp.add to $tmp.new before the diff and copy steps.

OpenBSD FAQ update all installed packages pkg_add -u pkgin update
💡 Result:
To update all installed packages on OpenBSD, you should use the native pkg_add utility [1][2]. OpenBSD does not use pkgin, which is primarily associated with NetBSD package management [3]. To update all installed packages, execute the following command as root: # pkg_add -Uu The command flags function as follows: -u: Tells pkg_add to update existing packages [1][2]. -U: When combined with -u, it ensures that installed packages are upgraded [4]. It is recommended to run this command regularly to keep software up-to-date [4]. The system will use the mirror configured in /etc/installurl to fetch the necessary files [2]. You do not need to provide a package name when using -u to perform a system-wide update [5]. If you wish to check which packages might need updating before running the upgrade, you can use the pkg_outdated(1) utility, which compares installed packages against the ports tree [6].

site:openbsd.org/faq/faq15.html "pkg_add -u" OR "pkg_add -Uu"
💡 Result:
In OpenBSD, the pkg_add utility uses the -u and -U flags for different update operations [1][2]. The -u flag is used to update installed packages. When run as pkg_add -u, it updates all installed packages and their dependencies to newer versions by relying on the PKG_PATH environment variable to locate the updated package names [1][3]. If specific package names are provided, only those packages and their dependencies are updated [1][4]. The -U flag is used to install new packages in a hurry by updating their dependencies first before installing the new package [1][2]. This option is primarily intended for use with -current snapshots [1]. While it can be faster than a full update, it carries a risk of leaving the system with an inconsistent set of packages [1]. Official documentation recommends using the standard -u flag to update all packages whenever possible to keep the system in sync [1][2]. There is no native pkg_add -Uu command; rather, these represent distinct flags with different purposes: -u is for general system updates, and -U is for dependency-aware installation of new packages [1][3]. The documentation for the bulk build tool dpb also references these flags, but they retain their distinct behaviors when invoked by the system [5][6].

site:man.openbsd.org/pkg_add "-U" "-u" update installed packages
💡 Result:
The flags -U and -u are specific to the pkg_add utility used in the OpenBSD operating system, where they serve distinct functions for managing software packages [1]. - The -u flag is used to update installed packages. When used without a specific package name, it attempts to update all currently installed packages on the system to their newer versions based on the configured package path [1]. - The -U flag is used to install new packages quickly. It updates the dependencies of the specified new package first to ensure compatibility. While it is generally recommended to use -u to update all packages before installing new ones, -U is a faster alternative, though it carries a slight risk of resulting in an inconsistent package set if not managed carefully [1]. These flags are not standard or universal across all package managers (such as apt, dnf, or pip), so their specific behavior should be verified against the documentation for the particular package management system you are using [1].

C standard atoi behavior result cannot be represented int undefined behavior strtol printf negative precision %g
💡 Result:
Regarding the behaviors specified in the C standard for the requested functions and formatting: atoi Behavior for Unrepresentable Results If the value of the result of an atoi call cannot be represented in an int, the behavior is undefined [1][2][3]. Because atoi is required to be equivalent to (int)strtol(str, (char)NULL, 10) except for error handling [1][4], and because it provides no mechanism to report errors (unlike strtol, which sets errno) [5][3], it is inherently unsafe for parsing strings that may fall outside the representable range of an int [1][5]. strtol Behavior for Unrepresentable Results When the value to be converted by strtol is outside the range of representable values for a long, the function returns LONG_MAX (if the value is positive) or LONG_MIN (if the value is negative) [6][7][8]. Additionally, the function sets the global variable errno to ERANGE to indicate a range error [6][7][9]. printf Negative Precision with %g For the printf family of functions, a negative precision specified in a conversion format is ignored, and the behavior is treated as if the precision were omitted [10]. Specifically for the %g (or %G) specifier, omitting the precision defaults it to 6 [11][12]. Negative precision does not trigger undefined behavior; it simply defaults to the standard behavior for that specifier as if no precision had been provided [10]. Top results: [1][7][10][11]

Validate precision environment variables before calling atoi.
pmPrintValue passes both environment values directly to atoi and uses the result as the %g precision. Malformed values can be partially accepted, and out-of-range values can invoke undefined behavior. Negative and zero values can produce precision behavior that differs from the documented defaults.
Parse each value with strtol, require a complete integer, check errno, and retain the default when validation fails. Add coverage for unset, valid, malformed, negative, zero, and oversized values.
