Pre-requisites
|
|
--------------
|
|
|
|
In addition to having notmuch, you need:
|
|
|
|
- gpg
|
|
- gnu tar
|
|
- gnu time
|
|
- xz. Some speedup can be gotten by installing "pixz", but this is
|
|
probably only worthwhile if you are debugging the tests.
|
|
|
|
Getting set up to run tests:
|
|
----------------------------
|
|
|
|
First, you need to get the corpus. If you don't already have the gpg
|
|
key for David Bremner, run
|
|
|
|
% gpg --search 'david@tethera.net'
|
|
|
|
This should get you a key with fingerprint
|
|
|
|
815B 6398 2A79 F8E7 C727 86C4 762B 57BB 7842 06AD
|
|
|
|
(the last 8 digits are printed as the "key id").
|
|
|
|
To fetch the actual corpus it should work to run
|
|
|
|
% make download-corpus
|
|
|
|
In case that fails or is too slow, check
|
|
|

|

|
|
Running tests
|
|
-------------
|
|
|
|
The easiest way to run performance tests is to say "make perf-test", (or
|
|
simply run the notmuch-perf-test script). Either command will run all
|
|
available performance tests.
|
|
|
|
Alternately, you can run a specific subset of tests by simply invoking
|
|
one of the executable scripts in this directory, (such as ./basic).
|
|
Each test script supports the following arguments
|
|
|
|
--small / --medium / --large Choose corpus size.
|
|
--debug Enable debugging. In particular don't delete
|
|
temporary directories.
|
|
|
|
Writing tests
|
|
-------------
|
|
|
|
Have a look at "01-dump-restore" for an example. Sourcing
|
|
"perf-test-lib.sh" is mandatory. Utility functions include
|
|
|
|
- 'add_email_corpus' unpacks a set of messages and adds them to the database.
|
|
- 'cache_database': makes a snapshot of the current database
|
|
- 'uncache_database': forces the next 'add_email_corpus' to rebuild the
|
|
database.
|
|
- 'time_start' unpacks the mail corpus and calls notmuch new if it
|
|
cannot find a cache of the appropriate corpus.
|
|
- 'time_done' does the cleanup; comment it out or pass --debug to the
|
|
script to leave the temporary files around.
|
|
|
|
Scripts are run in the order specified in notmuch-perf-test. In the
|
|
future this order might be chosen automatically so please follow the
|
|
convention of starting the name with two digits to specify the order.
