The virtual/podofo-build package pulls in dev-libs/boost, since packages which build against podofo will fail to build unless the boost headers are installed.

If we install Go source files without the corresponding static libraries, they we create a similar situation to the above.

Re: [gentoo-dev] rfc: Go ebuilds bundling multiple upstream sources
All, we have digressed a bit, so I want to bring the discussion back to what my main concerns are about this issue. 1. Should we bundle Go packages with Go software? If we do, except for the Go standard library which is part of dev-lang/go, do we need to bother with installing Go sources and packages at all? The down side of the whole bundling idea is that every consumer on someone's system could potentially have a different version of the Go package, which doesn't lend itself well to security concerns. This is why bundling is generally discouraged in Gentoo. Also, if we bundle, most of dev-go/* doesn't need to exist because these libraries would be bundled into and statically linked into the software that needs them. 2. How should we bundle? This is where my concern about consul and some other ebuilds comes in. The way the consul ebuild is written (putting the commit hashes of dependencies in SRC_URI) assumes that all of the dependencies will stay on github. This makes the ebuild far less flexable than go itself is. If we are going to bundle, I would rather have one tarball that includes all of the sources for consul and the dependent libraries dropped on the Gentoo mirrors. Such a tarball is very easy to create. Thoughts? William signature.asc Description: Digital signature

Re: [gentoo-dev] NPM / NodeJS project
FWIW, I also bumped into this in my previous job. I even wrote this (https://github.com/neurogeek/g-npm) which is incomplete but saved me a bunch of time creating a crazy amount of npm ebuilds. kinda rant My experience is, this isn't worth it. npm is a mess, is maintainer-unfriendly (although it might be argued that it is developer-friendly) and they basically don't care about about distributions at all. npm packages are not meant to be installed globally. They are content with having duplicate dependencies laying around everywhere. Their semantic versioning sucks. They 1.4.1.2 can break backwards compatibility with 1.4.1.1 and nobody cares. I didn't find a way to download specific versions, and had trouble when they did stuff like depend on 1.4.x, because of the above. Also, although minor point, the other reason I stopped pursuing this was because I think npm packages are needlessly small. So, you might want to install a package that depends on tens of other packages that depend on tens of packages themselves. Most of this packages are 10 lines of code. So, I ended up real fat with an dev-nodejs category with over a hundred packages. /kinda rant Having said all that, this was at least a couple of years ago. They might have come to their senses by now.

I'd like to say that Gentoo needs this kind of packages to stay actual and that our NOGO (yes that's an actual joke) on Go packages is not good for us nowdays. While it would certainly be possible to split out a number of separate ebuilds for Go libraries that are used *exclusively* by consul, what advantages would it have? Even in this limiting case, 1. You avoid pointless rebuilds. You rebuild the library (and probably the binary, for Go packages) when the library is upgraded rather than rebuilding everything whenever anything is updated. From my experience, Go packages don't take very long to build. +1, Go is not C, I have the same feeling 2. Security. If upstream treats the packages as separate, a user might hear that there's a security issue in libfoo but then run eix and see that he doesn't have libfoo installed (because it's bundled). That's a reasonable motivation. However, many of these libraries don't have any tags. So, you'll have to use the commit hashes if you want to test for vulnerabilities. In the case of the consul ebuild, the commit hashes of the libraries are available in the SRC_URI. I suppose that we could standardize a way to expose these. +1, there is no strong tagging on every upstream. Maybe that's another topic but handling git sub modules et al could be made easier while satisfying our QA (or maybe make some exceptions) 3. Chicken and egg problem. If the library only has one consumer and you keep it bundled with that consumer forever, then it will probably only ever have one consumer. If somebody wants to use it in an overlay or something he'd have to pull in the whole program. If a Go developer wants to use the libraries in question, then he'll probably use 'go get' to install them. I doubt the existence of an ebuild will have much relevance in people's decision to adopt a given Go library. 4. Ebuild complexity. Now you have to compile e.g. three packages in src_compile, install three packages in src_install, etc. The result is more complicated than building once, three times. In the case of the consul ebuild, all of the libraries are automatically built when the ebuild calls the emake. Even without a Makefile, Go makes it trivial to build the dependencies. Non live GIT ebuilds already make ebuilds more complex, this should indeed be enough. 5. One maintainer has to commit to maintaining all of the dependencies in addition to the program that he cares about. I guess that's a reasonable argument, depending on how much maintenance the dependencies require. Since there is no real Go support as such, this would be a pain ... Someone actually has to do the work to split out the libraries, so it may not be a clear-cut win in some cases. But it's nicer to have them split out should that happen by magic. Considering that Go binaries are statically linked, you'll end up with a bunch of Go libraries installed that you don't need during run-time. +1, this defeats Go's main advantage imho (not that I think it's smart, but it's the actual fact) Cheers

Should we bundle Go packages with Go software? If we do, except for the Go standard library which is part of dev-lang/go, do we need to bother with installing Go sources and packages at all? The down side of the whole bundling idea is that every consumer on someone's system could potentially have a different version of the Go package, which doesn't lend itself well to security concerns. This is why bundling is generally discouraged in Gentoo. Yes, as a general rule, bundling is sub-optimal. However, there are often exceptions to general rules like these, especially when there are competing concerns to contend with. I don't really see what the competing concerns are in this case. The competing concern is that un-bundling has some possibly undesirable consequences, mainly that it means we'll be installing static libraries that were only intended to be temporary build artifacts. It makes sense to install them if there are multiple consumers, otherwise it doesn't make much sense. Thinking about this, there may be a third option. This would take a slight reworking of the golang-build.eclass, but that is easy to do, and it would possibly remove the subslot from the dependencies. The source code is where the compatibility between versions of Go is, not the static objects, so what if, for third-party go packages, we skip installing the static objects? The only down side of this would be that there might be longer rebuilds if the packages have multiple consumers, but it gets rid of the static objects. What do you think?

I'm moving tomorrow and won't be able to tend to them if so, but I am interested in taking maintainership of it. I'm expecting to have Internet in my new home within a few weeks. There is a version bump bug (547460) and two other bugs. The version bump would be nice to do now (may be I will try to ask somebody to help me with it, as I have no amd64 hardware now). signature.asc Description: OpenPGP digital signature
