[gentoo-dev] Unification of variables used within SCM eclasses
As suggested by ssuominen on bug #311101, I am posting the issue
to the mailing list.
Currently, various SCM eclasses differ very much in the subset
of features and control variables implemented. The idea is to establish
a single subset of such variables and rules for all SCM eclasses
to follow, and maybe even develop a common scm.eclass which would be
sourced by other SCM eclasses.
Variables suggested by me:
a) Common variables - the variables which would have to be used by
various SCM eclasses as default/fallback values.
1. ESCM_DISTDIR (defaulting to PORTAGE_ACTUAL_DISTDIR/PORTDIR)
- an alternate parent dir to all SCM stores. It would be useful
if user would like to use an small file-inefficient filesystem
for main DISTDIR or rsync it with other machine (where SCM
files are not as important as the tarballs are).
2. ESCM_OFFLINE (most eclasses use it already)
- a common switch to easily switch off all network interaction.
3. ESCM_LIVE_FAIL_IF_REPO_NOT_UPDATED (similar to the one in git.eclass)
- a common switch to force unpack() phase to fail if no updates
were found during the pull/update.
b) Common eclass-specific variables - these ones should allow user to
override above variables for single SCM.
1. E*_STORE_DIR (defaulting to ${ESCM_DISTDIR}/*-src)
- already used by few eclasses, allowing user to change
the location where SCM-specific clones are stored.
2. E*_OFFLINE (defaulting to ${ESCM_OFFLINE})
- allowing user to override global 'offline switch'. Thus, it
should also support setting 'false' value to enable network
interaction for single SCM.
3. E*_LIVE_FAIL_...
- another override for the global one.
4. E*_REPO_URI
- the URI to the main repository. It might be extended to support
multiple URIs.
5. E*_REVISION
- explicit expected-revision/tag specification, preferably along
with implicit one (e.g. in ESVN_REPO_URI) deprecation.
This would allow applications to easily distinguish
between 'real' live ebuilds and snapshot ones fetching directly
from the repo.
c) Common export variables - these ones should be exported by SCM eclass
and stored in environment.bz2 after successful emerge.
1. E*_VERSION (or _REVISION, or ...)
- the version/revision to which the package was updated. This would
be useful to determine whether the current repo is newer
than one used when merging package.
2. E*_WC_PATH
- the absolute path to the last-used clone dir (i.e.
${E*_STORE_DIR}/sth) and thus the most probable location
to perform further updates in.
d) Other:
1. ESCM_CUSTOM_FETCH
- this one is not directly related to eclasses but for use of ebuild
authors. Setting this in an ebuild should notice applications
that the ebuild does use custom fetching procedures
(i.e. fetches from multiple repositories in a manner
unsupported directly by the eclass) and thus external
applications should not try to update the repository themselves.

Many external modules have not been ported yet to Python 3, so Python 2 still needs to be installed. You can benefit from having Python 3 installed without setting Python 3.1 as main active version of Python. Currently you should not set Python 3.1 as main active version of Python. When setting it becomes recommended, a separate news item will be created to notify users. Although Python 3.1 should not be set as main active version of Python, you should run python-updater after installation of Python 3.1. By default, modules that support both Python 2 and Python 3 are installed for both the active version of Python 2 and the active version of Python 3 when both Python 2 and Python 3 are installed. It is recommended to use a UTF-8 locale to avoid potential problems. Especially C and POSIX locales are discouraged. If locale has not been explicitly set, then POSIX locale is used, so you should ensure that locale has been set. Problems occurring only with non-UTF-8 locales should be reported directly to upstream developers of given packages.

That is why python is slotted; it is possible to have both versions installed at the same time.

[gentoo-dev] when to use a function and an implementation use flag.
I took a look at qemu-kvm and found something I percieve as funny: It had a gnutls use-flag, but no ssl useflag. As I see it is I want ssl/tls support it should be sufficient to enable USE=ssl and let the maintainer of said ebuild decide which implementation (if more then one) I am better off with and only care about the USE=gnutls openssl nss if i really think the maintainer is wrong. For qemu-kvm the problem is that there is only one implementation (i.e. gnutls), and if I want to have ssl support I have to enable gnutls for this package. When I wrote a bug about this I got a rather short reply from maintainer about pointing me to the policy about this. Now I know there was a disscussion a while back about this on the mailinglist, but google fails me to find it, looking into the Gentoo Development Guide [1] it fails me too. There is not a _single_ word about how to handle if there is only one implementation, but two use flags for this (one for the function provided - ssl - and one for the actual implementation - gnutls). So I have a question: Is there no policy about this? If there is could someone please point me towards it and also it in that case may be time to update the gentoo development guide.

AFAIK, this is the issue. If python-3 is installed, it will cause extra files to be installed, not justin python-3, but any packages that support both python-2 and python-3 will potentially get files installed for both versions of python. If having python-3 will cause stable users problems, then we probably shouldn't be stabilizing it anyway. AFAIK, the only problem we are debating about is the extra files being installed.

Fortunately or unfortunately, despite the stated Gentoo policy of documentation but not hand holding, stable Gentoo users are in fact used to having a bit of extra hand-holding and have come to expect it. While the generally given reason for said hand-holding is that we're simply avoiding the flood of bugs we'd otherwise get, and arguably that doesn't apply in this case (arguably, because there are still and will be new python dependency bugs that this will trigger), it's an expectation stable users have come to have, and failing to specifically mention the package.mask option violates this expectation. -- Duncan - List replies preferred.

On the other hand, I can see his point as well. The news item makes it very clear that python-3 cannot be the default python and that python-2 needs to be installed. It could be argued that he is just assuming that users are intelligent enough to figure out that they need to mask python-3 if they do not want it on their systems.

Not so cheerful, -- Ben de Groot Gentoo Linux Qt project lead developer Another user here. Couldn't this issue with the news item be resolved by wording it differently? The way I've understood the python maintainers is that they don't want the news item to recommend masking it. So couldn't a compromise be phrasing along the lines of ... it is safe to mask python-3* at the moment... and perhaps also ... a news item will be released when python-3* will become necessary. To be honest I don't think the last bit is quite as relevant if people do pay heed to the fact that python-3* can be masked without any consequence.

The news item makes it very clear that python-3 cannot be the default python and that python-2 needs to be installed. Again, if it *cannot* be the default python, then it *should not* be installed by default, which is what will happen if it's marked stable and users aren't told to p.mask it. Even then, it'll likely get installed first, as users will probably learn about p.masking it only *after* they install it. signature.asc Description: PGP signature
[gentoo-portage-dev] portage sources have moved from SVN to GIT
Hi, As the subject says, the portage sources have been moved from SVN to GIT [1]. The new repo is located on git.overlays.gentoo.org [2]. I've just updated the documentation to reflect this move [3] and it will be a few minutes before the html regenerates. If you have push access then you can commit something to the master branch like this: git clone git+ssh://g...@git.overlays.gentoo.org/proj/portage.git cd portage # edit files git commit -a git push origin master [1] https://bugs.gentoo.org/show_bug.cgi?id=196025 [2] http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=summary [3] http://www.gentoo.org/proj/en/portage/doc/testing.xml -- Thanks, Zac

In this mail - First thing to do - On origin - Not like Subversion: Commits in Git - Committing versus pushing - Non-linear history - Commits and the staging area - You in the future - Resources (lots of recommendable ones) - Questions? First thing to do = After cloning you need to set up your commit identity: git config --global user.name 'Dr. First Middle Last' git config --global user.email 'n...@gentoo.org' Missing that up front is more work later. On origin === The origin Zac mentioned is the name of a remote - a URI Git can pull from and (sometimes even) push to. Soon you will work with more than one remote: From personal experience I recommend to rename that remote to something more meaningful, something reflecting the involved host at best, e.g. git remote rename origin overlays-gentoo-org ^old^new Not like Subversion: Commits in Git Committing versus pushing - In Git you commit locally, even without network connectivity. You do a few local commits and push them to the server in an extra step: git commit git commit .. git push overlays-gentoo-org master In the beginning this separation may feel like a burden. You'll soon appreciate to have it. Commits and the staging area When you do git commit the content of the staging area (called index sometimes) is written into a new commit object. So modifying the staging area you change what goes into the next commit. Commands like git add file3.txt git add -u git add -p git reset do changes in the index for you. The index is one of the core features and differences to other systems including Subversion. Understanding the index is essential to working with Git. Please study online material on that topic. Non-linear history -- Due to its distributed nature - history is a directed acyclic graph (DAG) in Git, not a list - revision IDs are SHA1s, not plain numbers I can recommend emerging dev-vcs/gitg for a visual history browser. Present is on top, moving down is moving into the past You in the future = Now that we're on Git you'll soon be able (and expected) to re-order merge split clean-up past commits, i.e. re-write history.
