To achieve reproducible builds we use pip-tools to lock packages to a particular version.
|
||
|
|
Sadly this is complicated by the fact that Python can only tell us which transitive dependencies
|
||
|
|
are required by actually installing packages, and if you run pip-tools on a Mac or Linux machine,
|
||
|
|
it will miss packages that are required on Windows and vice versa.
|
||
|
|
|
||
|
|
So we're stuck manually merging dependencies for now. To update deps:
|
||
|
|
|
||
|
|
- run 'bazel run update' to update requirements.txt for the current
|
||
|
|
platform
|
||
|
|
- consult the git diff, and manually merge the changes, undoing the removal
|
||
|
|
of items pinned on other platforms
|
||
|
|
- repeat the process on the other platform
|
||
|
|
- run the tests to ensure nothing has broken on either platform
|
||
|
|
- commit the changes to requirements.txt
|
||
|
|
|
||
|
|
At the time of writing, Macs and Linux machines have identical output - it is only
|
||
|
|
Windows that differs. But we should not assume that will always be the case.
