Subject: [PATCH v3 0/8] Fixes for early logging/prints and related cleanups
Date: Wed, 19 Jun 2024 21:40:20 +0200	[thread overview]
Message-ID: <20240619194028.2913930-1-sbrivio@redhat.com> (raw)

The most apparent issue fixed by this series is the one from 4/6: with
a log file configured, we wouldn't print to standard error anymore,
during initialisation, which means that users such as libvirt lost
the ability to report meaningful error messages that occurred during
initialisation, in that case.

v3:
- add 2/8: we don't really need --stderr anymore
- in 5/8, save errno at the beginning of the _perror() helper
- in 7/8, avoid assigning errno to whatever return code we have just
  for the sake of using the new helpers: strerror() is actually less
  convoluted than that
- add 8/8: there's no need to call __openlog() with a log file

v2:
- turn flag bitmap into simple, separate boolean flags
- move errno description after message in _perror() functions
- make some of the old perror() messages more descriptive

*** BLURB HERE ***

Stefano Brivio (8):
  conf, passt: Don't try to log to stderr after we close it
  conf, passt: Make --stderr do nothing, and deprecate it
  conf, log: Instead of abusing log levels, add log_conf_parsed flag
  log, passt: Always print to stderr before initialisation is complete
  log: Add _perror() logging function variants
  treewide: Replace perror() calls with calls to logging functions
  treewide: Replace strerror() calls
  conf, passt: Don't call __openlog() if a log file is used
