[Python-Dev] Committing bsddb 4.6.4, and where can I put testsuite temp files? (original) (raw)

Hi Jesus,

Regarding where to place test files, you might want to look at how the current bsddb test suite in Lib/bsddb/test handles the need to create temporary files and such. A bit of work has gone into this particular aspect to improve reliability and robustness on buildbots -- particularily when it comes to Windows. (I believe the current test suite comes up with a unique directory based on process ID..)

    Trent.

I just committed pybsddb 4.6.4 to python svn. My next step (after a successfull buildbot cycle, I hope!) is to commit the new testsuite. First I need to review any changes there since I maintain pybsddb.

The testsuite creates a lot of files/directories while working. Fine, since it cleans later, unless some test crashes hard. My testcode defines a variable to the path I want to use to keep those files/dirs. Currently it is "/tmp/z-BerkeleyDB", or something like that.

Since my code allows for testcases to be run in multiple threads and/or processes, where would be a sensible path choice for temporal files?. Current working directory would be fine, if "somebody" is cleaning after running all tests.

Ramdisk ("/tmp" in some systems, for example Solaris) would be nice, since some test uses transactions, and transactions are write-synchronous.

In my system, runnning all tests serially (you can run all of them in parallel, if you wish) takes about 15-20 seconds. Far faster than current tests in python svn, and that can be improved even more.
