addon+version uniqueness won't be compatible with MV3 (new version format)

[willdurand]

The addon+version uniqueness implemented in #135 will not be compatible with MV3 because we encourage a new simpler version string format in the manifest. In practice, it means:

• letters are no longer allowed
• the string should have between 1 and 4 numbers separated with dots
• each number should have up to 9 digits
• for non-zero numbers, leading zeros are not allowed

We'll need to update the build step to account for that when MV3 extensions will start to be signed. At the moment, MV3 extensions won't be accepted by the linter, though (the linter task is blocking for privileged add-ons since #169).

This bug is semi-related to this issue, although the XPI is an MV2 extension: https://bugzilla.mozilla.org/show_bug.cgi?id=1795750

We'll need to update this code when we decide what the version should look like.

We could do major.minor.dot.YYmmddHHM, which would allow a unique build every 10 minutes. Or specify that addons pipeline web extensions can only specify major.minor, and do major.minor.YYmmdd.HHMMSS to keep the current unique-to-the-second versioning.

It seems there's a warning about this in Firefox now mozilla-extensions/aboutsync#110

I'm thinking of going with major.minor.YYmmdd.HHMMSS

We probably need to document the fact that extensions will only be able to use major.minor in their manifest. Ideally this limitation would be enforced in CI (in the https://github.com/mozilla-extensions/xpi-template repo?) so that everyone knows about the limitation.

[willdurand]

One more thing: HH might produce leading zeros, which are not accepted by the new version format.

Can you please reconsider this new format?

[willdurand]

Sorry, I don't think that's an option.

FYI, I landed a patch to update the version string in langpacks: https://bugzilla.mozilla.org/show_bug.cgi?id=1796531

@gabrielBusta hey, any progress on this? (I am just curious, this is the last identified bug I have for the rollout of this new version format) Thanks!

Yay, thank you!
