- Subject: testsuite report: individual test time
Hi,
FYI, I've written a script (prefix-time.sh) to prefix lines with the
amount of seconds it took to produce that line.
Using that script, I traced a gdb testsuite run:
...
$ tail -F gdb.sum -n +1 | ./prefix-time.sh 2>&1 | tee LOG
...
Using the trace result, I can get the following histogram (1 test took
60 seconds, 11 tests took 10 seconds, etc):
...
$ sed 's/:.*//' LOG | sort -n -r | uniq -c
1 60
11 10
2 9
3 8
1 7
3 6
8 5
6 4
21 3
103 2
966 1
75846 0
1 _
...
At a more detailed level, these are the ones with time > 5:
...
$ sort -n -r LOG | more
