Not being around at the time, you may not know some of the history, but feel free to ask Ciaranm if you need a more authoritative source. The thing is, EAPI-0 was not originally completely specified, and to my knowledge, remains that way, because that would have been real-world essentially impossible to do. Instead, a convenient shortcut was taken. EAPI-0 was defined as what portage did at the time, with EAPI-1 for sure and I believe EAPI-2 at least, being defined as the the previous EAPI, with specifically defined changes, but with the base EAPI still only fuzzily defined as, basically, what portage did at the time. And since the beginning, while there have been other unapproved EAPIs not allowed in the main gentoo tree, because portage was and remains the official default PM, no EAPI has been approved for main-tree deployment until portage had a working implementation. So while portage can and certainly does have bugs where it doesn't meet EAPI requirements, particularly for behavior there since EAPI-0 and not specifically defined to be different in a specific EAPI since then, to the extent that PMS applies at all, the interpretation of PMS must still be read in the context of what portage did all those years ago with the original EAPI-0 spec, since EAPI-0 was /defined/ based on portage behavior at the time. Which then begs the question[1] I asked, how old /is/ this dynamic-deps behavior? Does it extend back to EAPI-0? My gut sense from memory as a user back then and now is that it does, but that's simply a gut sense I'm ill equipped to go back and verify. --- [1] Begs the question: Yes, I'm aware of the legal and philosophical "circular logic" usage, now generally legacy in terms of real-world use except in the philosophic and legal areas. I deliberately choose to use the phrase in the newer and now much more common sense, rhetorically personifying the question such that it can "beg to be asked". -- Duncan - List replies preferred.
