Users of multiple repositories seem to appreciate the freedom that is brought with this small-but-effective(TM) feature. So what about doing the same in Portage? Rationale: User should be able to force the installation of atoms from specific overlays without worrying too much if others or the main tree feature a greater release. Feature-testing overlay maintainers can make sure that packages are pulled in from their "sources", which could potentially contain reworked/improved/critically-changed ebuilds. Adding "@overlay" atoms/deps postfix support could really make life easier, especially because forcing specific atoms in *DEPEND hoping that these will be always pulled in from the same overlay is not something reliable, as you already know.

Your @ is still a prefix for the repository name. For usability's sake, please don't do this. I can imagine users getting confused over the different meanings of the @ sign. I do not want to trigger a discussion like the one PHP had when choosing namespace separators, but we got the "::" established in Paludis and Paludis is used by way more Gentoo people than equo.

"::" C++/PHP/whatever separator has nothing to do with the purpose of "@overlay". Paludis is not a Gentoo project and doesn't follow Gentoo features validation rules. So is Entropy. If Paludis has its own syntax it doesn't automatically mean that Gentoo Portage *has to* follow it.

Personally I think the PHP namespace syntax issue is a very good analogy. There's an established syntax, even if it's not a written standard, already used in a very similar situation, and that should be taken into account. > Paludis is not a Gentoo project and doesn't follow Gentoo features > validation rules. > So is Entropy.

As far as I can see, a discussion is happening. You started a discussion here and others mentioned that there is a specific syntax already used for this by a very similar application. You appear to be the only one who's arguing against that syntax. As a user, I have to agree that using @ for multiple purposes, even if it can't be applied to the same purposes in different locations, is potentially confusing, even if not just plain silly. As a side note, I think I've read somewhere that it may in the future be possible to specify sets in package.* (which I assume would be done using the @set-name syntax), but can't remember where off-hand. This may have just been a suggestion, but if it ever is implemented, it would surely add to the confusion.

If it's got an @ at the beginning, it's a set name. If an atom has an @ after the package name (and possibly version etc) it means "from that overlay." Note that I think we can use the syntax elsewhere, without ambiguity. Surely it would be best simply to ask end-users which of a few variants they'd find easiest to work with?

Using it at a location other than the beginning for something else is possible and I'd adapt, but it /is/ confusing. :: lacks that confusion. It does have the additional complication of needing quoted or escaped in the shell, but users are supposed to do a --pretend anyway, and after it doesn't output what's expected, a user of any shell experience at all should conclude with little delay that it /could/ be the escaping even if they aren't sure, and a quick suitably escaped trial will confirm it.

I'm not sure about this particular usage case as I haven't quite wrapped my mind around how to test it without it actually being at least stubbed into portage to test (not that I've spent too long trying, but given your question, a few seconds contemplation lead me to the conclusion that there was more to it than I might have than I thought), but bash completion at lest wants escaped colons in paths (and tab-completes them escaped with \), for instance, and shell scripts often use colons as field separators for filenames or paths as well, due to the relatively low frequency of use. It was the shell path stuff that I was thinking about when I cautioned about escapes. Maybe that doesn't apply in usage such as users would be using with portage? To confirm the above shell (well, shell completion) issues, I just created a dir ~/::test. Trying to tab-complete just a single colon produced unexpected results (either a listing of the entire parent dir, or :\:\:test, an extra colon, which naturally then failed to work as :::test didn't exist, depending on what I was tab-completing), while tab-completing a backslash escaped colon produced the desired results. Similar results if I tried to tab-complete a double-colon. When I tried to remove the ::test dir. rm -ri ::<tab> resulted in a completion of ::::test/, which of course gave me an error saying it couldn't find ::::test, but rm -ri \:<tab> completed correctly, and the rm succeeded. A retest typing in the entire name, ::test (thus NOT using tab- completion), however, worked correctly, so perhaps it's more accurate to say it's a bash-completion bug, while the shell itself works fine. Given that, we'd probably be OK at least until the gentoo-bashcomp update, and perhaps it could be worked around there. -- Duncan - List replies preferred. No HTML msgs.

This is what I would dislike about the '@' character. I'm ok with :: though. If we use repo_name as the overlay identifier, we must rethink how layman-global.txt is currently handled. Many overlays in there have that file missing, and some have different identifiers than what layman displays as their name. Is this specifier stored and considered on future dependency calculations (e.g. updates, dependencies of other ebuilds on the package that was installed via @overlay)?

Unfortunately, that value is not known until the repository is checked out. Doing that on every "list" operation would be too much overhead.

Since the consensus is for using it as part of the UI, you don't need to wait for EAPI=4, you (lxnay) can start writing patches for portage (regardless of which operator is used) to recognize such atoms on the command line. -- ~Nirbheek Chauhan ^ permalink raw reply [flat|nested] 25+ messages in thread

Won't this just lead to dependency hell? With horrible dependencies between different overlays? The current system of "overlays" being restrictive is (IMO) beneficial in the long-term because it forces people to move stuff to the main tree instead of going the lazy way and putting inter-overlay dependencies. If the concept of "overlay" is taken as "feature overlays", then dependencies should not go beyond the main tree + the overlay itself. -- ~Nirbheek Chauhan ^ permalink raw reply [flat|nested] 25+ messages in thread

No. This is a terrible idea. The solution is to *fix the overlays*, not force the user to intervene and fix things himself. Conflicting overlay issues turn up on the Gentoo forums (check Unsupported Software), and in pretty much all cases, once the maintainer(s) of the overlay(s) are contacted about the issue, the overlays are quickly fixed so that the next update sorts out the user's tree. Users should *not *have to take steps to fix overlay blocks and breaks ahead of time; that should be the overlay maintainer's job, not the poor end user. > Comments are welcome, flames are not. On that note, I'd like to offer a friendly word of caution, in the interests of us all talking together and working through the ideas presented in your threads. In your last visit to our mailing list (http://thread.gmane.org/gmane.linux.gentoo.devel/55180), you stated that you'd like to make some sweeping changes to Gentoo, then you started telling the developers why they all sucked ahead of time for not implementing said ideas. And then you kept telling developers that they sucked throughout the rest of the replies. You expressed unwillingness to work with Gentoo developers through our admittedly long recruitment process, instead wanting to push your changes to our tree directly. There wasn't very much accomplished on either side at the end of that debacle, except some hurt feelings. It seems that the discussions you're having in the binary packages and overlay threads are already heading the same direction, and I for one don't want that to happen. Telling people they're not allowed to express disagreement is counterproductive.[1][2] [1] http://thread.gmane.org/gmane.linux.gentoo.devel/61555/focus=61568 [2] http://thread.gmane.org/gmane.linux.gentoo.devel/61530/focus=61560 So, folks, just take it easy. We don't have to accept every suggestion offered to the list, nor do we have to reject it out of hand. Thanks.
