While of course I agree that any input from 'outside' is welcome and valuable, yet to get things done, in my opinion the final decision should not be blocked by from any alternative package manager and some policies should be enforced. But on topic, what's a counter proposal for my idea then? Quick search in archives gave me some results I don't particularly like, like the idea with /etc/portage/packages.cflags and /etc/portage/package.env, and they have been dropped for similar reasons - as the former needs special parsing instead just sourcing the script (the problem is that someone needs to implement this - this is usually the problem, especially in pure volunteer projects like Gentoo), the latter looks a bit messy to me. /etc/portage/env would be the best approach when made officially supported (recently it looks like /etc/portage/env is sourced multiple times and that should be fixed, for convenience, just in case user wants to put: CFLAGS="-O0 -ggdb" CXXFLAGS="${CFLAGS}" FEATURES="${FEATURES} nostrip" (or even USE="${USE} debug") actually /etc/portage/env could easily replace package.keywords and package.use as well and introduce replacement for meybe-proposed-sometime package.features - I wonder whether it's been discussed already. -- regards MM signature.asc Description: This is a digitally signed message part.

I think that I probably did not express my idea as well as I could have, since most of the responses I have gotten have echoed your thoughts that Gentoo does, indeed, have the facilities to achieve flexibility in logging, etc. I totally agree. Gentoo's capabilities, although not perfect, of course, are superlative and are a complement to its superb online doc. I think that's a big reason why we're all here - we see this and appreciate this. In fact, even when I do not include the word "gentoo" in a Google search, I more often than not end up at a Gentoo doc page - this is impressive. However, what I see as perhaps a missing "piece" is more conceptual: the important connection between the valuable info in the emerge logs (and their somewhat transient default nature) and what a user looks for when he/she has a problem with a package. Yes, users will realize this as they use Gentoo (and will start paying more attention to logs as a result), so I don't think it's a huge problem, but what this particular user said to me made me think that there is, perhaps, an opportunity to improve the situation. There is no Gentoo-specific "readme" facility, which could be the obvious and de facto place to go when trouble is had. I can imagine that a fairly simple and low-effort way of starting such a resource would be to simple echo the log output into a package-specific file in a known place (or put it in the portage db). The logging facilities allow similar things if configured to do it, but it is not on by default. Once users know where to go to see the "instructions" or "notes" on getting a package up and running after installation, this would become a good place to have such info or to expand on how the facility works. Starting with just the plain emerge log output would be an easy way to get benefit of such a concept has merit. And by no means would such a thing be an attempt to replace the excellent on-line docs or wiki, either - I see both as having unique strengths. For example, for detailed info on packages, the wiki/web stuff is the better resource. For a quick check of whether a revdep-rebuild might have been necessary after installing a new package would typically be in the log/notes. The notes also have the key advantage that they would *always* contain what the log output was, whereas whether a wiki or web page exists on a particular package depends on whether someone spent the time to author one. My intention with the RFC was to see if the concept has any worth and to kick it around a bit. I do not really see this as a deficiency in Gentoo's technology (which I have a feeling is how many here have interpreted it), but simply something that, if done correctly, could be useful. -Joe

Summarizing from what I've read in this thread it seems you want to find a way to help user find information s/he doesn't look for. If users aren't curious about their system they will sure have a hard time figuring out how to fix it if needs be. PORTAGE_ELOG_* isn't really that hard to find in the make.conf.example (even though it's new location makes it a bit harder to find). As others have said, there are already proper systems, documentation and linking through other docs. Not finding this is what I'd call lazyness or lack of google foo. Don't misunderstand me, some stuff can get ouf of the radar of everyone, it's ok, real people are still here to point you in the right direction. If you find a better way to convey these information to the users, then please surprise me.

I'm afraid you're mistaken here. The point is to look at this from users' (well, a bit) point of view - USE=debug variable is ambiguous in it's meaning. While it enables only codepaths (asserts, #ifdefs and similar) it suggests (by name and for some packages not only suggests) enabling debug symbols. And policy is to enforce CFLAGS from make.conf and wipe out every package- defined flags as far as I know. > For the most part, USE=debug means "enable debug code paths", which for > lots of projects simply means "enable assertions"; there are packages > that take this as "enable debug symbols too" but I don't think that's > very valid since users might want debug code paths but not symbols and > vice-versa (I indeed have debug symbols bug no debug codepaths enabled). That's correct, the problem is - Gentoo does not provide officially supported mechanism of enabling both or just debug symbols per package basis - it doesn't even provide any supported/documented mechanism for per package CFLAGS, FEATURES and similar. If /etc/portage/env hack/feature could be made official (for CFLAGS,LDFLAGS and bash-domain FEATURES) - it could address this issue good enough, because with proper smart combination of symlinks/files the "ultimate configuration" power would be delivered, not just "cleaning/workaround" I am actually proposing. Per package debug/release/profile/or_any_other configuration is what I would pursue, and in my proposal I used USE=debug as existing and supported way of achieving this. While I don't like hack @pve uses (I prefer portage/env as more convenient way), his idea about emerge --info seems interesting. > - -ggdb *does not have any runtime performance hit*; neither in Yes, I'm well aware of that, though it increases disk space requirements a bit as it's applied to all libs/bins. > - -O0 is not always a good idea; beside bugs in packages concealed by >-O1+ [1] [1] is a pathology and should be fought against, -O1+ may leave frame stack useless for debugging due to inline optimizations in some places (especially debugging inline class implementations is limited, which affects Qt/KDE) - besides - I may not stated it clear - those default values would be defined in the very same make.conf, so it could be: CHOST="x86_64-pc-linux-gnu" CFLAGS="-march=nocona -O2 -pipe -msse3 -ftree-vectorize" CXXFLAGS="${CFLAGS}" CFLAGS_DEBUG="-O2 -ggdb" Yet, I still cannot think of this proposal other way like of dirty workaround for the problem, that doesn't really exist (well, at least for developers, who have meta-distribution and ultimate freedom for user in mind). For the users the problem is real, of course it's usually a consequence of either not being aware of those mechanisms or as a result of ambiguous semantics of USE=debug. And what about pushing some bash-domain FEATURES to USE flags? Like nostrip, splitdebug? I guess being able to set it per package is important. -- regards MM signature.asc Description: This is a digitally signed message part.

Those exceptions are nostrip and splitdebug at least, besides I intend to keep it bash (or ebuild) level only - to preserve simplicity and yet functionality. FEATURES_DEBUG was a clean and convenient approach of me being unaware of FEATURES internals - thanks for clarification. FEATURES little inconsistency problem needs to be addressed.

Yeah I still think that there is no point in requiring using of a specific API when the same data can easily be available in a format that is more or less parsable with ease in any modern (and non) programming language.

(also there is complexity Duncan told you about...) Personally to get build with symbols I use a trivial wrapper around emerge: demerge() { env USE="debug" CFLAGS="-O2 -pipe -g -ggdb" PKGDIR="/vt/binpkg-debug" \ FEATURES="buildpkg splitdebug collision-protect ccache noclean installsources" \ emerge "$@" } and I use demerge whenever I need to debug package. I'm sure this is just a quick hack which could be greatly improved to track which packages are installed with or without symbols.

For the most part, USE=debug means "enable debug code paths", which for lots of projects simply means "enable assertions"; there are packages that take this as "enable debug symbols too" but I don't think that's very valid since users might want debug code paths but not symbols and vice-versa (I indeed have debug symbols bug no debug codepaths enabled).
