  Hello, all.
 
  After a few days of thinking, discovering and working, here it is.
  The first working draft of new git eclass codenamed 'git-r3'.
 
  First of all, the name is not final. I'm open to ideas. I'm open to
  naming it 'git-r1' to put it in line with my other -r1 eclasses :).
  I'd definitely like to avoid 'git-3' though, since that version-like
  naming was a mistake as almost-'python-2' eclass shown.
 
  Secondly, it's not even final that there will be a new eclass. Most
  likely I will commit it as a new eclass since that way is easier for us
  but if you prefer I may try to get it and git-2 more API-friendly
  and work on making it a almost-drop-in replacement. Since, after all,
  internals have actually changed much more than the API.
 
 
 Hi,
 
 I have no capacity to review the eclass right now (although I promise
 I will soon)
 but I was wondering why the whole eclass is inside the  if [[ !
 ${_GIT_R3} ]]  block.
 Is it so you can avoid inheriting the same eclass twice? I haven't
 seen that before
 so I was wondering if that's the only reason. If yes, then maybe this
 needs to be solved in PM scope instead?
 As in, prevent portage from inheriting the same eclass twice instead
 of handling this case in the eclass itself.

Yep, it's exactly that. All my new eclasses use that, and vapier's use
rather some 'spank' serpentines. Plus mine have 'EXPORT_FUNCTIONS' out
of it, so wrapping them does not change export order.

I suggested that into EAPI [1] but it didn't get in so far. The issue
is that some eclasses may actually need to be sourced twice, e.g. due
to environment changing. Though they are nowhere near 'sane' then.

 Do you have any plans to add support for sparse checkout?
 
 Something like this
 
 |cd parentdir
 git clone -n url
 cd repo_dir
 git remote add –f name url
 git config core.sparsecheckout true
 echo /foldername/  .git/info/sparse-checkout
 git checkout tagname

Considering our specific work flow, I think it would be enough to do:

  git checkout branch [dir1 dir2 ...]

Depending on the need for it, I can either add it as optional arguments
to git_checkout or an envvar for it.


 
 What about subtrees?

Looking at their specific design, don't they work out-of-the-box?

  5. Safer default EGIT_DIR choice. EGIT_PROJECT removed.
  
  Since submodules are cloned as separate repositories as well, we can't
  afford having EGIT_PROJECT to change the clone dir. Instead, the eclass
  uses full path from first repo URI (with some preprocessing) to
  determine the clone location. This should ensure non-colliding clones
  with most likeliness that two ebuilds using the same repo will use
  the same clone without any special effort from the maintainer.
  

[snip]

  5. EGIT_PROJECT - should be no longer necessary.
  
 How so?

Point 5. over there :). It is supposed to choose perfect clone location
itself now.

 3. sys-fs/bedup's btrfs-progs submodule says the given commit id is
 'not a valid branch point'. Need to investigate what this means.
 
 4. 'git fetch --depth 1' seems to be refetching stuff even when nothing
 changed. Need to investigate it. It may be enough to do an additional
 'did anything change?' check.

Those are fixed now. The eclass has been adjusted to work properly with
branches, tags and commit ids. It also avoids shallowing repo that was
unshallowed already (since we expect that one of the packages needs it
non-shallow), and properly unshallows shallow repos ;).

Attaching the new version and a diff.

Also it won't harm to make the unpack location configurable, so can we

[gentoo-dev] [PATCH] gnome2-utils.eclass add support for gdk-pixbuf cache update

2013-08-31 Thread Gilles Dartiguelongue
As described here:

https://bugs.gentoo.org/show_bug.cgi?id=483128

This is a very lightweight patch to support the few packages that
provide gdk pixbuf loaders. The ones I know of are: gdk-pixbuf itself,
librsvg and libopenraw and emul-gtklibs but more could be missing simply
because they do not run the command.

Since this patch is quite trivial, I'd like to have it commited by
Sunday. Thanks.

I am attaching the patch here as well for convience.

Well, 'cat' is not atomic at all, so definitely not that :). 'mv' is
the only command that you can expect to at least try to be atomic.

It may had something to do with file metadata or symlinks.

In gdk-pixbuf, something like:

 Dropping some keywords to unstable on minor arches.
 
 If we grow (like you said below), then doing less seems like a decision
 that we shouldn't take; it is rather about doing it different to use
 our resources in a better way. Crowd sourcing users is an option here...
 
 And about recruiting, it is the only way we can keep moving with
 getting distro, which makes bigger and bigger all the time.
 
 Yes, but apart from recruiting you can make the resources used better;
 if the current way of using our resources isn't sufficient, we can
 improve that as well. Improving both is going to make the difference.
 
 I would have joined recruiters unless i knew how difficult job they
 are doing.
 
 Yes, I am interested in both mentoring and recruiting and I need to
 contact them again; but I do not really intend to point at recruiters
 here or how hard that is, what I intend to point at with recruiting is
 finding those users that are willing to learn to write better ebuilds
 and are willing to become a Gentoo Developer. They are hard to find;
 and in order for them to be found, a mentor has to find them somewhere.
 
 Came across three types of people already trying to find a mentee:
 
 1. The first one doesn't want to go through the amount of time it takes;
this depends a bit on the queue, but it can take months.
 
 2. The second one's interest to become a Gentoo Developer depends from
time to time; so, tries to start over and over to become one.
 
 3. The third one writes a lot of ebuilds (and has an overlay that
looks like a gold mine), but there is a language barrier that keeps
the user from contributing; so, we take things slowly instead...
 
 4. The fourth one leaves a message on IRC and quits before you return.
 
 5. ...
I know we are a little OT here but the fifth type of recruit is someone
who is very excited, very dedicated, and completely unable to find a
mentor.  That is where I was for a long time, no one seemed to have the
time to mentor me.  Personally I think that is a big issue in the growth
of gentoo, if we all take a little time out to be mentors there will be
more gentoo devs and we will get more done.

- -ZC
 
 So, recruiting in the terms of finding recruits appears to be hard.

   Why not mv or cp? Also you need '|| die' here since 'cat' can fail
   writing.
  
  I'd have to look back at the original bug report to get the exact reason
  but it seems mv/cp was not atomic enough.
 
 Well, 'cat' is not atomic at all, so definitely not that :). 'mv' is
 the only command that you can expect to at least try to be atomic.
 
 It may had something to do with file metadata or symlinks.

I sort of remember there was a bug report but I can find no trace of it.
All I could find was the commit that introduced this logic, by lxnay:

http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/x11-libs/gdk-pixbuf/gdk-pixbuf-2.24.0.ebuild?hideattic=0revision=1.2view=markup

@lxnay, could you please comment on previous question ?

   And please ensure to remove it in pkg_postrm() when last version
   of gdk-pixbuf is unmerged.
  
  I am not clear on this last sentence. Could you reformulate it please ?
 
 In gdk-pixbuf, something like:
 
 pkg_postrm() {
   # TODO: check if i used the correct variable :)
   [[ ${REPLACING_VERSIONS} ]] || rm -f ${EROOT}usr/.../loaders.cache
 }
 

ok, will do.

Your recruitment bug disagrees with you here in that you had a mentor

The netmon@g.o alias never saw mail from you before your recruitment
bug was openend, so how could anyone have known you were trying to
attract a mentor and do netmon stuff?

I don't see any mail on gentoo-dev or gentoo-project either.

There are exactly *nill* bugs that you reported and were (subsequently)

It can indeed be though to find someone with time. But there are
certainly people that do have time and are willing to mentor; it's just
that, you've got to find each other at the right time and place.

Which makes me think we should have some way to list people that are
willing to become Gentoo Developers as well as Gentoo Developers that
are willing to mentor people. Perhaps on the Gentoo Wiki?

That would turn the easy to miss anyone want to mentor me? or random
probing do _you_ want to be my mentor? into an approach where it's a
matter of looking at a list, contacting someone and you are set.

 Personally I think that is a big issue
 in the growth of gentoo, if we all take a little time out to be
 mentors there will be more gentoo devs and we will get more done.

 Your recruitment bug disagrees with you here in that you had a mentor
 right from the start.

The recruitment bug is filed by the mentor; the bug on it own marks the
time at which a mentor is willing to mentor the mentee, but it does
not reflect the time at which he started to look for a mentor.

 I don't see any mail on gentoo-dev or gentoo-project either.

This makes me wonder if that is a good or bad idea; on the one hand, it
would be nice to see a mentee step up and look for a mentor on the MLs
but on the other hand that might result in some noise. After all, the
relation between a mentor and a mentee is from person to person; and
not from person to list. It's not really a discussion; so, I don't
feel like it necessarily belongs on the MLs, unless as announcement.

Even if this were considered a good idea, then how would we get people
to advertise themselves on the mailing lists?

There seem to be two things we need to think about:

1. Where do people find the information on how to find a mentor?

2. Where do we want people to look for a mentor?

But that's one side of the story; the other side has the same
questions, but at least has an answer. Mentors find the a mentee (eg.
nice bug reporter) between a lot of people (eg. all bug reporters); so,
it's like finding signal in a lot of noise. What we need on this other
side, might be better tools to find outstanding users; but that on
their own take some time to implement and might not gain much.

So, I'm rooting for having a central list where mentors and mentees can
find each other; I think that that would give the best of both worlds.

 The netmon@g.o alias never saw mail from you before your recruitment
 bug was openend, so how could anyone have known you were trying to
 attract a mentor and do netmon stuff?

 ...

 There are exactly *nill* bugs that you reported and were
 (subsequently) CC'd or Assigned to netmon@g.o.

Not everyone wants to immediately start out on a herd.

 You have only yourself to blame.

Since when did this become a game of blame with him?

Ah, I like this idea better than the list on Gentoo Wiki I was trying
to approach; the only downside I can imagine if it were a single person
that might not respond in time (busy / devaway / MIA), so I think we
should at least aim to make it a mail alias with multiple persons.

We could then list people on some project page; but, only their
forenames or nicknames and not their actual full name and e-mail such
that their private details can stay private if they wish to.

I'd rather leave it. The diff is more for pretty-printing anyway, it

 Also it won't harm to make the unpack location configurable, so can we
 please have a variable like EGIT_SOURCEDIR or EGIT_UNPACK_DIR (as it
 was called in git.eclass)?

I've added EGIT_CHECKOUT_DIR :).

Re: [gentoo-dev] git-r3: initial draft for review [v3]

2013-08-31 Thread Michał Górny
A few more changes.

1. Added EGIT_CHECKOUT_DIR to control the place where stuff is checked
   out.

2. Moved the defaults from src_fetch() and src_unpack()
   into git-r3_fetch() and git-r3_checkout(). This makes using them
   easier, like:

   git-r3_fetch http://repo1
   git-r3_fetch http://repo2
   git-r3_checkout http://repo1
   git-r3_checkout http://repo2 ${S}/foo

3. Added prototype pkg_isuptodate() function [bug 482666 [1]].

   (I will update it when we decide on how the func should be named :))

As an additional testing tool, I attached the version of git-r3
converted to git-2 compatible API. IOW, a drop-in replacement that you
could use to test the new eclass internals with API almost fully
compatible with the old one.

I remember actively seeking out mentors and recruiters on irc for a

wider audience than just the recruiters is a good idea, why limit

the recruiters, just a note that more people means more bandwidth.

I like the idea of having a wiki page of people willing to be mentors

 start pulling ~arch packages that were never tested against the stable
 tree. It so much better if stage3 was also ~arch.
 
 Do we actually have examples of this happening?  I've never had
 problems with a mix of stable and ~arch keywords.  Granted, I'm not
 running ~arch on most libs.
 
 I've seen lots of talk about stable being less reliable than ~arch,
 and ~arch applications on a stable core being unreliable, but I've
 never actually seen any real evidence that either is true.  Granted,
 I'm not necessarily expecting a scientific study, but I haven't even
 heard anecdotes.  I can't offer much personally - I only really use
 stable to any extent and I find it works just fine other than the
 occasional need to unmask something.
 
I unmask/keyword things as needed for Pentoo and I can't say I've ever
noticed a lack of stability due to it.  I have a (mostly) stable base of
@system packages and key things like DE's most of the time, but I also
randomly mix in an ~arch package or two when I need to.  Almost all of
the security tools I put on Pentoo are ~arch, and many of them pull in
some random ~arch libs, etc.  I can't say I've never had an issue but as
long as we all keep the deps are correct as possible it really isn't an
issue.

Just my $0.02

As a sidenote, that is exactly what --autounmask-write does as well. Meaning 
whoever uses this very nifty portage feature will end up with such a mix of 
stable and testing as well.
