lib: Confine the copy_no_nl memcpy to debug_gpfs_log()

2024-01-04T17:06:19+00:00

gpfswrap_add_trace() seems not to have a format string that could
understand the %.*s notation.

While there this removes >4k of r/w memory from every smbd.

lib/util: add debug_set_forced_log_priority()

2023-11-24T09:30:38+00:00

By default the priority for syslog/systemd is derived from
the log level of the debug message.

But for things like startup messages we want to
change the priority temporary, like this:

debug_set_forced_log_priority(DBGLVL_NOTICE);
D_ERR("Startup...\n");
debug_set_forced_log_priority(-1);

util: Avoid logging to multiple backends for stdout/stderr

2023-08-28T01:21:07+00:00

Commit 83fe7a0316d3e5867a56cfdc51ec17f36ea03889 converted the
stdout/stderr logging  types to DEBUG_FILE to get a header when using
DEBUG_SYSLOG_FORMAT_ALWAYS.  However, this causes all configured
backends to be invoked.  When syslog is one of those backends then
this is almost certainly not what is intended.

Instead, call debug_file_log() directly in that special case and
revert the parts of the above commit that convert to file logging.

Most of the changes to debughdrclass() still seem necessary, since
they handle the change of debug_syslog_format from a bool to an enum.
