Subject: [Libburn-hackers] cheat tests proposal
|
||||||
|
|
||||||
|
Hi,
|
||||||
|
|
||||||
|
Here is a cheat list of performance tests I have in my mind for testing the
|
||||||
|
whole thing, for instance before release. This list does not depreciate the
|
||||||
|
practical use case pattern of a potential user or developer might happen to
|
||||||
|
have. The are put together to second-guess he potential testers, and anyone
|
||||||
|
can perform them at will (even partially) on a best effort fashion. I won't go
|
||||||
|
that deep to assign them artificial weights or priority.
|
||||||
|
|
||||||
|
1) Various compilation tests, like:
|
||||||
|
export CPPFLAGS=-DLibburn_use_sg_dummY; ./configure
|
||||||
|
repeat for the adapters of the all target OSes, there should be other
|
||||||
|
interesting macros, static check logs can easily reveal them:-)
|
||||||
|
This can be scripted of course.
|
||||||
|
|
||||||
|
2) Inspect the static check logs:
|
||||||
|
(revision numbers are well indicated)
|
||||||
|
http://people.debian.org/~danchev/xorriso/sclogs/
|
||||||
|
|
||||||
|
3) Inspect previous versions build daemon logs (various architectures, three
|
||||||
|
kernels: linux, kfreebsd, hurd) for interesting compiler warnings or errors:
|
||||||
|
http://buildd.debian.org
|
||||||
|
I'm sure I've seen FreeBSD public build logs before, but my searching fails so
|
||||||
|
far!
|
||||||
|
|
||||||
|
4) Testing xorriso in dialog mode:
|
||||||
|
perhaps this 'proof of concept' toy could be helpful:
|
||||||
|
http://anonscm.debian.org/gitweb/?p=users/danchev/medistimator.git;a=summary
|
||||||
|
this requires some specific knowledge of how the tool works (there are
|
||||||
|
hopefully very helpful comments in the source), to interpret the results and
|
||||||
|
compare them with the previous runs; my logs could be found at:
|
||||||
|
http://people.debian.org/~danchev/medistimator/log/
|
||||||
|
the aim is to catch speed performace hits, corectness of results, crashes, etc
|
||||||
|
when working on various input data trees, like very large BD-sized ones.
|
||||||
|
|
||||||
|
5) Profiling tests with gprof. We did that once :-)
|
||||||
|
|
||||||
|
Each of these tests has already caught a flaw or another, so they are stolen
|
||||||
|
from the past experience we already had. The list of course if open for adding
|
||||||
|
more interesting checks, like real burning ones for instance. I'm sure I
|
||||||
|
forgot at least one, since I had 6 in mind... Alois....
|
||||||
|
|
||||||
|
6) jigdo production.
|
||||||
|
|
||||||
|
I'll try to simplify a run like that one:
|
||||||
|
|
||||||
|
xorriso -as mkisofs -r
|
||||||
|
-checksum_algorithm_iso md5,sha1,sha256,sha512
