Access to workdir on the build server?

[Rainer Müller]

Hello Janosch,

thank you for contributing these ports for MacPass!

I think this topic would have been better on the macports-dev@ mailing list, as
it reaches more developers that can help with writing Portfiles.

First of all, this port must be updated with a proper versioning scheme. You
cannot use the git commit hash, because the version must have a defined sort
order. Hashes are "arbitrary" values and with just two hashes, there is no way
to tell which one is newer. This is important as with the current versioning
scheme the port might never show up as outdated. The port would only be upgraded
if the next hash happens to be sorted alphabetically after the current one.

Normally tagged releases should be preferred, but apparently there are no recent
tags that are suitable for MacPass and KeePassKit.

For repositories without tags, a common option would be to use the date of the
commit in YYYYMMDD format. Or if this will return to "normal" version numbers at
some point, start from the last tagged release 2.4.7 and add an increment as a
suffix, such as 2.4.7-snapshotYYYYMMDD or similar.

To correct this you will also have to increment the 'epoch' of the port, as that
is the only way to ensure the new version number format will upgrade all
existing installation.

Your suspicion is correct, all buildbots run on case-sensitive filesystems.
Direct access is not possible and it is wiped directly after the build as disk
space is a rare resource for this setup.

You can already see it when inspecting the tarball directly:

$ tar tf 76e6ecda942f9e328efde7883ad75aed7290b632.tar.gz
KeePassKit-76e6ecda942f9e328efde7883ad75aed7290b632/
...

I am not sure if there is a canonical way to solve this with the github port
group, but I think it could work to set the worksrcdir with the right
capitalization:

worksrcdir    KeePassKit-${version}
