Description Seymore 2008-07-28 14:40:41 UTC
When starting a fresh gentoo install, app-text/iso-codes did not compile. This package is needed for gnome-light at least. After installing pyxml, it did compile. If iso-codes requires pyxml, should not this explicit in the ebuild?

dev-java/commons-lang-2.0-r2 also failed with the same error. 

The error was:

I havent tried to reproduce this (other than trying to emerge a dozen times after my attempted fixes). 



Reproducible: Didn't try
Comment 1 Carsten Lohrke (RETIRED) gentoo-dev 2008-07-28 15:10:42 UTC
I doubt dev-java/commons-lang depends on pyxml. May it be that you updated from Python 2.4 to 2.5, but missed to run python-updater, as instructed by the post-install message?
Comment 2 Seymore 2008-07-28 15:24:06 UTC
(In reply to comment #1)
Python updater was actually my first guess, but I did run it. Then downloaded python-eselect (or whatsitsname) and actively selected python-2.5. Then proceded to uninstall python-2.4. I also did several revdep-rebuilds. 
Also, pyxml wasn't outdated, it was simply not there. 

I just installed dev-java/commons-lang and now it did compile. 

That said, the error message got 4 or so hits on google, so chances are this is not a very common problem. 
Comment 3 Carsten Lohrke (RETIRED) gentoo-dev 2008-07-28 17:49:22 UTC
iso-codes-1.5 comes with the following information

ChangeLog:821:  * Allow iso-codes to build without pyxml. Patch thanks to
ChangeLog-822-    James Henstridge. Closes: #331357, #328152.

seems that wasn't all - or do we speak about the iso-codes-0.58 ebuild?


> I just installed dev-java/commons-lang and now it did compile. 

You may be irritated by error message being repeated at the end of the emerge run. This particular piece of software doesn't use python at all.
Comment 4 Gilles Dartiguelongue (RETIRED) gentoo-dev 2008-07-28 21:17:02 UTC
my amd64 box doesn't have pyxml installed but iso-codes compiled well. You message refers to a missing Sax parser but the file in the message belongs to python.
Comment 5 Seymore 2008-07-29 08:59:06 UTC
I might be mistaken about commons-lang. 

But I did "emerge -C pyxml" and "emerge iso-codes" and then iso-codes failed. After installing pyxml, iso-codes compiled. So there is some relationship between the two. 

the ebuild is for app-text/iso-codes-1.5

My guess is that I dont need pyxml *in particular* but that I need some package for taking care of the same thing pyxml does. 


Comment 6 Daniel Gryniewicz (RETIRED) gentoo-dev 2008-09-05 16:16:00 UTC
All that xml stuff is in python 2.5.  It's possible that something that was an external package in 2.4 but included in 2.5 got unmerged (portage was doing that briefly).  Could you re-emerge python 2.5 and see if that fixes your problem?
Comment 7 Carsten Lohrke (RETIRED) gentoo-dev 2008-09-07 15:22:59 UTC
The default xml parser is pyexpat, which comes with python, unless the "build" use flag is used, which is reserved for bootstrapping purposes exclusively and entirely unsupported. Unless there's a bug in the expat detection during the Python build, this likely is a plain invalid PEBKAC issue.

Is this an issue with the Gentoo release media or are you building the stages yourself?
Comment 8 Vlastimil Babka (Caster) (RETIRED) gentoo-dev 2008-09-07 20:56:36 UTC
To clarify about the java packages, python xml code is used in dev-java/javatoolkit used in the java eclasses, more info in bug 236377.
Comment 9 Seymore 2008-09-08 10:31:08 UTC
As far as I'm concerned, the problem is solved. I have had no more problems with iso-codes or pyxml. If you guys can't find anything obviously wrong with ebuilds/dependencies, I'll bet it's just my twisted system who's to blame. 

Therefore, I say we just put this bug as "resolved", until at least one more encounters this "bug". 

(If this is really nagging someone, however, I'll be happy to run tests and such on my box.)
Comment 10 Carsten Lohrke (RETIRED) gentoo-dev 2008-09-08 15:09:24 UTC
Seymore, it would be just nice, if you'd answer my above question and also tell if /usr/lib/python2.5/lib-dynload/pyexpat.so exists on your system.
Comment 11 Juan M. Medina 2008-10-25 01:24:23 UTC
(In reply to comment #10)

> 

Not sure about what Seymore case is, but I did update from 2.4 to 2.5, ran python-updates and eselect-python, and pyexpat.so is NOT in the system.

Seymore kind of answered that on Comment # 2 2008-07-28 15:24:06, mentioning that pyxml just wasn't there.

Of course, as soon as pyxml was installed, the issue got addressed, since this installs pyexpat.so.

Comment 12 Julie Haugh 2008-12-07 17:28:25 UTC
I also saw iso-codes fail to build on a fresh install from media.  The version of dev-libs/expat that was on the system was 1.95.8, but emerge'ing expat updated it to 2.0.1.  So, I'm thinking there is a missing dependency that just so happens to be satisfied before people miss it.  But from a clean install, iso-codes will fail because pyxml hasn't been installed.  Once pyxml has been installed, iso-codes installs successfully.

One observation of mine is that from a fresh stage3 install, "emerge gnome" finds a number of missing dependencies.  Needing to emerge pyxml before emerge'ing gnome is just one of the missing dependencies.
Comment 13 Gilles Dartiguelongue (RETIRED) gentoo-dev 2008-12-09 13:53:33 UTC
Summing up, either one of python-2.5 or pyxml provides the xml parsing modules. I think I'm just going to put a || ( >=dev-lang/python-2.5 dev-python/pyxml ) in DEPEND and be done with it as it has been said that missing pyexpat in python 2.5 is a result of using build USE flag.

@herd what say you ?
Comment 14 Mart Raudsepp gentoo-dev 2008-12-09 14:27:46 UTC
Yes, USE=build in installed packages beyond bootstrap is wrong and unsupported as far as we care
Comment 15 Andrew Gaffney (RETIRED) gentoo-dev 2008-12-09 18:09:46 UTC
It looks like this problem stems from the 'expat' USE that was just recently (~36 hours ago) to the python ebuild. It's disabled by default, so anyone emerging python isn't going to have expat support. Perhaps this should be IUSE="+expat" instead.
Comment 16 Andrew Gaffney (RETIRED) gentoo-dev 2008-12-09 18:14:27 UTC
CCing vapier since he made that change to the python ebuild.
Comment 17 Mart Raudsepp gentoo-dev 2008-12-09 22:07:26 UTC
CCing actual maintainers of python. It sounds like this change wasn't agreed to by them as they'd surely know the affects?
Comment 18 Mart Raudsepp gentoo-dev 2008-12-09 22:16:51 UTC
vapier already default enabled it. Do we need to start built_with_use checking now, because he doesn't like USE=build, when expat support should only be avoided for bootstraps I think?
Comment 19 Seymore 2008-12-09 22:34:23 UTC
I'm not quite sure what the current discussion is about. However, if the comment in #15 says the OP's (ie. my) problem stems from something that happened 36 hours ago, that is not so. This thread goes back to the end of July. 

Apologies to you all for not answering Carsten Lohrke's question:

1. I do not have the "build" flag enabled in make.conf or /etc/portage/package.use 
 I did not know of such a flag, and I cant remember ever removing one. 

2. I was using a release media (medium?), though which I cannot say. Probably the one that was available around july. 
Comment 20 SpanKY gentoo-dev 2008-12-10 00:20:52 UTC
it's always going to be an issue with USE=build and USE=expat.  fix the packages in question to have proper USE checks.

python should have USE=build dropped anyways, but that's a different issue.
Comment 21 SpanKY gentoo-dev 2008-12-10 03:52:59 UTC
leio: and you might want to get your information straight rather than make random conjectures about things you're not knowledgeable about
Comment 22 Mart Raudsepp gentoo-dev 2008-12-10 10:22:29 UTC
I guess we should start with getting portage to check for USE=expat on python for glsa.py to work...
Unlike USE=expat, that sometimes selects between libxml2 and expat, USE=build should never be enabled after bootstrap. USE=-expat is a completely valid global configuration when the user prefers libxml2 or the like. The correct USE flag here to use is either none (always enable) or IUSE=xml in my opinion. Of course when that gets disabled, breakage ensues too, potential breakages we'd like to know before or shortly after the change for all affected packages or teams, instead of having to find out the hard way long afterwards when damage is not minimal anymore. But I guess this isn't a perfect world...

It is also customary to mention in the ChangeLog on whose authority a non-maintainer commit is done when it's a non-trivial change (like a change that causes breakages for stuff that didn't need to built_with_use check before but now needs to).

As for the original bugs, perhaps expat-1.9x to expat-2 made xml module not work for a while because the ABI broke and stuff using expat needed rebuilds with revdep-rebuild?
Comment 23 Jesus Rivero (RETIRED) gentoo-dev 2008-12-10 14:06:38 UTC
<crazy thought>
    What if we add a SLOTTED version of Python or just another package for python, like python-embedded-2.5.2, python-livecd-2.5.2 or python-minimal-2.5.2 for this cases?
</crazy thought>

    What I mean is, as python-2.5 integrated a lot of stuff into it from python-2.4 like ElementTree, pySqlite and ctypes (to name some) some new packages may assume that python already provides those elements and we can have tons of missing deps or namespaces changes leading to apps usage errors. This way, people needing a minimal python for whatever reason can use the version freely without ever wondering if a small change on an ebuild may break portage. 

    Another thing, please, read Python Project's documentation to properly make changes to dev-lang/python ebuilds. We found out about the USE flag change cause some users starter to have issues with cElementTree not working after a Python upgrade. 

    Best regards,

Here's another crazy thought; how about USE=minimal? :p
Comment 25 Wim 2009-01-15 09:07:30 UTC
Just reporting I had the same problem. On a seriously outdated system I was/am updating, iso-codes failed in the same way as the original bug. It installed without problem after first installing pyxml.
(so my problem is solved)

Some more info I see might help:
I do not have /usr/lib/python2.5/lib-dynload/pyexpat.so even after installing pyxml.
I've done both python-update and revdep-rebuild.

Comment 27 Gilles Dartiguelongue (RETIRED) gentoo-dev 2009-01-18 21:53:37 UTC
hopefully fixed in 3.5.1. Please reopen if it's not the case.
Comment 28 Sascha Hlusiak 2009-01-29 15:44:30 UTC
I wasn't able to compile app-text/iso-codes-3.5.1 until I emerged dev-lang/python-2.5.4-r2 with USE="xml". You might want to check for that use flag; I don't have pyxml installed. Please reopen.
Comment 29 Gilles Dartiguelongue (RETIRED) gentoo-dev 2009-01-29 15:55:42 UTC
yeah somebody changed it recently and didn't check what it was breaking.

Maybe like this:

2.3 isn't in the tree anymore, and I have no clue what we'd need to require for 2.6.

So if neither python[xml]or pyxml are installed things go pear-shaped.

Comment 33 Gilles Dartiguelongue (RETIRED) gentoo-dev 2009-02-04 00:02:15 UTC
@patrick, why the r1 ? it's a _dep_ fix only.

Plus the change you did is afaik undefined because each version of python in tree as a variation the following use flags build, xml or expat.

A simple egrep "USE" *.ebuild |egrep --color "xml|expat|build" will convince you that there is no uniformity and hence we cannot use USE deps properly, at least not with the scope you set it to.

hence reopening.

@python, can we get this USE story straight please ?
Comment 34 Peter Volkov (RETIRED) gentoo-dev 2009-02-10 13:25:57 UTC
Ok, I've dropped 3.5.1-r1 since it's broken even in simple case of mixing branches. I thought about this solution:

    || (
        dev-lang/python:2.4[-build]
        <dev-lang/python-2.5.4-r2:2.5[-build]
        >=dev-lang/python-2.5.4-r2:2.5[-build,xml]
        dev-lang/python:2.6[expat]
        dev-python/pyxml )"

but it'll break as soon as python herd fix something in :2.5 slot. So probably it's good idea to have a bit more consistent USE flags in :2.5 slot or please designate version after which it's 100% xml USE flag will not change.
Comment 35 Jesus Rivero (RETIRED) gentoo-dev 2009-02-10 16:28:32 UTC
Hello everyone, 

   Ive updated every python ebuild in portage and in python experimental overlay. Now they all have +xml and build use flags. So, you can freely check for [-build,xml] regardless of the version. 

   Sorry for any inconveniences!. 

   Best regards, 
Comment 36 Daniel Gryniewicz (RETIRED) gentoo-dev 2009-02-13 17:00:13 UTC
Thank you very much, Jesus.  This is fixed now.
