QA Fixups#2726
Conversation
Exact wording and even the number of detected errors varies across platforms, so filter away the differences.
More recent versions of man(1) are reporting:
warning: table wider than line length minus indentation
... just need a bit more T{ ... }T wrapping for some longer fields
in the table.
Let the shell find the executable.
When using -m and nothing is missing.
The default install on openSUSE Tumbleweed leaves the nobody account really locked down, and in particular expired. This means $ sudo -u nobody ... fails. Claude helped diagnose this and suggest a way to fix it, so I've included the test and fix in qa/944 ... it seems to be the only QA test exposed to the issue.
Tweak a couple to reduce table width.
man/man1/pmcpp.1
man/man1/pmlogcompress.1
Don't let table width warnings in man pages kill the build ...
scripts/man-lint
Seems to have been overlooked ... cloned from libpcp_archive pc.in file and makefile rules.
Mostly so I can use -D ...
Still not working on vm01, but this is helping the triage.

- Line 115: In the diagnostic handling around the non-filtered `$tmp/err` path,

and error counting behavior.
- Line 152: Update the unsuccessful connection path in the nonblocking
connection logic to assign the current socket error to real_sts immediately
before __pmCloseSocket(s), covering timeout, select failure, and
__pmConnectCheckError() failure paths so the verbose pmErrStr(-real_sts) report
reflects the failed attempt.

Restore the original nobody account expiration.
When shadow field 8 is nonempty and sudo usermod -e '' nobody succeeds, the command clears the expiration. _cleanup does not restore it, so the test can leave the host account policy changed. Restore the value immediately after sudo -u nobody id; the exit trap is installed only later.
Suggested fix

Export the private static link dependencies.
libpcp_web.a is installed for development consumers, but libpcp_web.pc.in omits the private dependencies used by the build. These include the installed libvalkey.a archive, math and regex libraries, and configured SASL, OpenSSL, libuv, SQLite, inih, and PCP MMV dependencies.
Add a generated Libs.private entry. Use -lvalkey for the installed Valkey archive instead of the build-tree archive path. Requires.private is suitable only for dependencies that provide matching pkg-config packages.

@coderabbitai our pkgconfig files in PCP are pretty lame ... it is a much larger piece of work outside the scope of this PR and I'm not even sure it is technically feasible across all the platforms we build and package PCP for. This one is similar to all the other ones we're using for second-level PCP libraries (libpcp_pmda. libpcp_archive, etc) and so I think it will suffice for the time being.

@kmcdonell, thanks for the context. I checked the existing templates: libpcp_archive and libpcp_pmda also omit Libs.private. I agree that a consistent, cross-platform fix is outside this PR. The missing static-link dependencies remain a limitation, but I will not press for a change here.
Would you like me to open a follow-up issue for the second-level PCP pkg-config files?

Learning: In Performance Co-Pilot, the second-level pkg-config templates `src/libpcp_archive/src/libpcp_archive.pc.in` and `src/libpcp_pmda/src/libpcp_pmda.pc.in` omit `Libs.private`. The maintainer considers a consistent, cross-platform treatment of their static-link dependencies a separate task, outside the scope of PR `#2726`.

Report a failed account-expiration restore.
If $sudo usermod fails during cleanup, the script still reports that the expiration was reset and clears nobody_expiration. A transient account-file lock or permission failure can therefore leave nobody unexpired while the test reports success. Check the restore status, retain the saved value on failure, and fail the test rather than reporting a reset. (github.com)
