I'm in a hurry right now and I haven't read all of the replies to this topic in
the other thread, so I'm sorry if this has already been discussed.
I like the idea of enabling package renaming because I am generally in favor of
breaking a few packages temporarily if it means that we can bring a naming
scheme in line with official policy*. Overall it leads to less
I suggest that name changes be logged (old name, new name, date, maybe user
name, possibly hidden from public view) and that the log be made available via
an RPC interface, a static plaintext page in a simple format, or a dynamic
plaintext page with get variables similar to the query RPC interface. An
accompanying RSS feed of the changes made in the last month would be good too.
When a package complains about unavailable dependencies, users can check the
log and inform the maintainer or update the package if it's theirs. AUR helpers
will be able to scan for name-changes automatically too and handle that
accordingly (e.g. by informing of the user or maybe even by handling it
Log maintenance should require minimal effort as long as the data is stored in
a parsable way. Entries could be purged after 1 year to avoid excessive clutter
(which shouldn't be an issue anyway, because we won't be renaming many
packages). Not effort is required to handle multiple renames either as the log
can be scanned from top to bottom to find multiple changes, e.g.
foo -> bar
bar -> baz
AUR helper: "Aha, foo is now baz."
If the AUR detects that a package depends on a renamed package then it should
send an automatic notification to the maintainer if possible because the AUR
does seem to support some rudimentary dependency parsing, i.e. by naming deps
on the package page.. Anything beyond that would be unnecessary in the presence
of a log as the users will pass along the information.
Parsing all PKGBUILDs would be imperfect and require too much overhead.
Automatically updating packages would be disastrous.
I hope that this is still on-topic.
* That sounds eerily totalitarian. "Dear citizen, your package foo has been
renamed Xte562FS42 according to party policy. Sugar rations have been raised
this week to 15g."
