The logging APIs need to be able to generate formatted timestamps
using only async signal safe functions. This rules out using
gmtime/localtime/malloc/gettimeday(!) and much more.
Introduce a new internal API which is async signal safe.
virTimeMillisNowRaw replacement for gettimeofday. Uses clock_gettime
where available, otherwise falls back to the unsafe
gettimeofday
virTimeFieldsNowRaw replacements for gmtime(), convert a timestamp
virTimeFieldsThenRaw into a broken out set of fields. No localtime()
replacement is provided, because converting to
local time is not practical with only async signal
safe APIs.
virTimeStringNowRaw replacements for strftime() which print a timestamp
virTimeStringThenRaw into a string, using a pre-determined format, with
a fixed size buffer (VIR_TIME_STRING_BUFLEN)
For each of these there is also a version without the Raw postfix
which raises a full libvirt error. These versions are not async
signal safe
* src/Makefile.am, src/util/virtime.c, src/util/virtime.h: New files
* src/libvirt_private.syms: New APis
* configure.ac: Check for clock_gettime in -lrt
* tests/virtimetest.c, tests/Makefile.am: Test new APIs
