[Bug 1875708] Autopkgtest regression report (systemd/245.4-4ubuntu3.2)

Thu Jul 16 05:31:45 UTC 2020

All autopkgtests for the newly accepted systemd (245.4-4ubuntu3.2) for focal have finished running.
The following regressions have been reported in tests triggered by the package:

apt/unknown (armhf)
indicator-session/17.3.20+19.10.20190921-0ubuntu1 (arm64)
dovecot/1:2.3.7.2-1ubuntu3.1 (armhf)
postgresql-12/unknown (armhf)
mir/unknown (armhf)
systemd/245.4-4ubuntu3.2 (amd64)
umockdev/unknown (armhf)
policykit-1/unknown (armhf)
asterisk/unknown (armhf)
anbox/unknown (armhf)
php7.4/unknown (armhf)
ksystemlog/unknown (armhf)
polkit-qt-1/unknown (armhf)

Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].

  Truncated messages in journald since systemd v244

Bug description:
  [Impact]

   * since 09d0b46a "journal: refresh cached credentials of stdout streams"
     in ~244 output may be trincated.

   * Upstream has a fix in https://github.com/systemd/systemd/pull/15685

   * Backporting the fix will avoid truncation of log output to journald

  [Test Case]

   * This could happen in any case, but is more likely when a program that 
     has output going to journald is spawning short-lived sub-programs often.
     Therefore the test emphasizes on that:

     - Use a test service like /etc/systemd/system/test.service:
  [Unit]
  Description=Test Truncate
  After=network.target

  [Service]
  ExecStart=/usr/lib/test.sh long-test-for-start
  ExecStop=/usr/lib/test.sh long-test-for-stop
  Type=oneshot
  RemainAfterExit=yes
  StandardOutput=journal+console
  TimeoutStopSec=0

  [Install]
  WantedBy=multi-user.target

     - And a test script like /usr/lib/test.sh:
  #!/bin/sh
  gettext "This will"
  echo
  gettext "usually fail"
  echo
  gettext "and be truncated"
  echo 

  Start/Stopping that service without the fix will look like:
  Apr 30 18:56:40 f systemd[1]: Stopping Test Truncate...
  Apr 30 18:56:40 f test.sh[1165]: T
  Apr 30 18:56:40 f test.sh[1167]: T
  Apr 30 18:56:40 f test.sh[1167]: sually fai
  Apr 30 18:56:40 f test.sh[1165]: s
  Apr 30 18:56:40 f test.sh[1168]: s
  Apr 30 18:56:40 f test.sh[1168]: nd be truncate
  Apr 30 18:56:40 f test.sh[1165]: n
  Apr 30 18:56:40 f systemd[1]: test.service: Succeeded.
  Apr 30 18:56:40 f systemd[1]: Stopped Test Truncate.

  [Regression Potential] 

   * The patches are rather small, but there might be a slightly increased 
     memory consumption of journald for output buffers. 
   * Issues (if any and I couldn't find any so far) should be only to 
     journald output handling. Systemd is huge, this at least narrows
     down the potential places of a regression a lot.

  [Other Info]

   * n/a

  Hi,

  when I shut down my machine I see messages from /usr/lib/libvirt
  /libvirt-guests.sh but there are 2 anomalies:

   - 3 libvirt-guests.sh processes are run
   - messages are truncated
