Reverse engineering
|
|
|
|
|

...................

|
|
|
|
|
|
|
|
|
It’s a lot of Django reverse engineering combined with a strong test suite.
|
|
|
|
|
|
Such a test suite is crucial for a reverse engineering project.
|
|
|
|
|
|
If some important part of Django changes and breaks the expected behaviour,
|
|
|
|
|
|
you can be sure that the test suite will fail.

Monkey patching
|
|
|
|
|
|
...............
|
|
|
|
|
|
|
|
|
|
|
|
django-cachalot modifies Django in place during execution to add a caching tool
|
|
|
|
|
|
just before SQL queries are executed.
|
|
|
|
|
|
We detect which cache keys must be removed when some data
|
|
|
|
|
|
is created/changed/deleted on the database.
