Bugzilla Bug 41124

dev-perl/XML-Parser not in dependencies for gnome-vfs-2.4.2-r1

Reproducible: Always

2.emerge gnome-vfs-2.4.2-r1
3.

Actual Results:  
ebuild stops while configure

it deps on >=intltool-0.29 which deps on XML-Parser.

Conclusion:
Something perl needs to be fixed.

perl problem needs explanation.

The problem is that the warning, issued at the end of all installs of the
perl-5.8 series, and discussed to no end on the mailing lists a year or so ago
now, was not heeded. When upgrading from a major point release of perl, modules
and executable code compiled against the 5.6.X version of perl must be
re-installed. The location of XML-Parser, in this case, is in a perl 5.6.1
directory which is not part of the user's @INC anymore. This is not a gentoo
perl issue.

Timo - for what it's worth, there is a script in <PORTAGE>/dev-lang/perl/files/
called libperl_rebuilder which does a decent attempt at helping out. It isn't
perfect, but what it does is to essentially look for any perl related ebuilds
you have installed (modules, etc) and attempt to re-emerge them. Hope this
helps!]

-Mike

Sorry for all the posts, its the work of coffee in my system this morning.

Timo/foser - the problem with XML::Parser is that it is compiled as xs code, i.e. against libperl and the libxml libraries to produce a binary module that is usable by perl. When upgrading from 5.6.X to 5.8 (and if you're playing with the beta releases, within some of the 5.8.x tree as well) the API used by perl to interface between external libraries and the perl intrepeter has changed. The rebuilder script I mentioned rebuilds any perl modules and perl dependant items that you have emerged in the past to overcome this change. It is at best a hack (I can say that as I wrote at least the first incarcation of it) and may be overkill in this case. Re-emerging the XML::Parser and related modules will solve your problem in the short term, but the long term problem is that any module you installed under 5.6.1 that isn't *pure* perl but that instead links to something external will fail until rebuilt. This is actually covered in the perl release notes and easily verified. I hope this helps,

-Mike

due to this amount of bug-reports maybe we should add a XML-Parser dependency
directly?

The packages already dep on xml-parser via intltool. The problem is  xml-parser
_needs_ to be rebuild after a perl update, but there is no way to tell that to
portage. Portage sees the xml-parser package as already being installed and
moves on to the next dep. Adding xml-parser as a direct dep would have no
effect towards that.

Ok, but I've never had perl 5.6 on this system, so I'm not sure why it would
have caused a problem.

I wonder how feasable it would be to incorporate interoperability between
either portage and CPAN or each ebuild working with CPAN. I'm new to gentoo,
but CPAN would seem ideal. Although I do remember cpan being a kinda nasty last
time I used it with slackware 10

Because people still add themselves to this bug, a note (over a year later).
libperl_rebuilder has been replaced with perl-cleaner, which is by most
accounts cleaner, faster, --oneshot, and guaranteed to make your hair grow

in my 2005.0 system, there is no libperl_rebuilder around, but instead, we shall
use:

/usr/portage/dev-lang/perl/files/perl-cleaner all
what may do a bit too much, but which will hopefully fix the bug the Gentoo way.
I write this repport at once, and hope this script will fix my box before tonight.

Note that XML::Parser is the perl module. In any case, NOBODY should ever try
emerge XML::Parser
thats a very strange mistake.

:: is the module seperator for Perl, not the package descriptor for portage !!!

I dont even think
emerge XML-Parser
should ever be run, since perl-cleaner is alreade THE SCRIPT designed to solve
the actual problem.

BUT: I think that updates of perl should warn and remind to run perl-cleaner to
rebuild everything cleanly.

Perl does and has for over a year now. The problem is that it gets lost in the 
shuffle of mass updates (no solution available to that). Also, perl-cleaner has 
been broken out from that version and is now emergeable as its own application 
(for future inclusion as an option to revdep_rebuild).

Okay. What is an end user (such as me who filed the above bug (and apparently
wasted my time)) supposed to do? It appears this has been a problem for a very
long time. Over a year.

perl-cleaner modules worked for me but I never saw the message to run this as 
my update went by as part of an emerge -uD world. Perhaps there could be a 
portage enhancement to summarise these types of messages at the end of an 
emerge operation?

Oh, god. Why don't we just add an explicit dependency on XML-Parser on the said
Gnome packages' ebuild?

That might not be the solution for people doing emerge syncs (see Comment #78,
for example), but it will at least solve issues with *fresh* GRP 2005.1
installations.

Is it *that* hard to put an extra line on the RDEPEND entry in the ebuild?

reply @ #85

Its not that simple.  all of theese people already have XML-Parser installed.
-all- of them.

They also failed to rebuild it when they updated perl, so the module wasn't
found with the current perl install. This is a symptomous bug in the current
setup where an upgrade cannot force rebuilds of all sub-dependancies.    Nothing
will be solved by the added DEPEND.

Does perl have the equivilant of python-updater or revdep-rebuild?  Could it be
run automatically when perl is upgraded?

there is perl-cleaner,  but it cannot be automated.  We don't invoke "emerge"
from inside "emerge" , that would cause a horrid can of worms to come into being.

And really, perl is too big to just PDEPEND on everything ever built and linked
against it...  I'm sure you wouldn't want to open that mess either, right?


you -get- told to run perl-cleaner, but the problem here is once more, that of
people not seeing/Caring about the notes given to them post-emerge.

I can certainly understand not wanting to run emerge from within emerge.

Maybe ebuild needs an "after" function, that schedules some program to be run
after emerge ends?  The, that could run things like revdep-rebuild,
perl-cleaner, python-updater...

Nah, we can just say "run perl-cleaner" and close the bug.

we probably don't want to do that sort of thing from a stability standpoint. 
Ie, since many of the "after" tools could well require human supervision, 
Double installs of python and such items come to mind,  then we don't just want
to be there and force things down their throats.

Anyhow, this is digressing into a portage featurism discussion. 

Solution: run perl-cleaner. dupe bug 41124

bother w/ reading ebuild instructions after perl upgrade and/or searching for

I have a fresh AMD64 install, an intended upgrade.  I copied over my world file
and had ebuild work through it... and guess what I find.

Somehow intltool is built, perl is rebuilt, and XML::Parser is missing.

With the amount of duplicates here, I think forcing a XML::Parser dependency is
a good idea.  The module is specifically searched for in (for example)
gnome-mime-data's ./configure.  As described above, intltool will bring it in,
but if it's already installed but perl's moved around or reinstalled,
XML::Parser dies.

Maybe emerge needs to know more about Perl...

*** Bug 125064 has been marked as a duplicate of this bug. ***

(In reply to comment #103)

Won't help anything at all, it's already installed. You *must* run perl-cleaner
after upgrading perl.

*** Bug 125811 has been marked as a duplicate of this bug. ***

"perl is rebuilt" means recompiled from the same version.

When I was doing the emerges to rebuild my rig for AMD64, Perl would alternate
between 5.8.7 and 5.8.8 many times.  It would downgrade, then upgrade, then
downgrade, then upgrade, and I hadn't touched my /etc/make.conf and
/etc/portage/package.keywords.  Even if I hit perl-cleaner to reinstall
XML::Parser (it was installed before), XML::Parser was missing.

Yes, I know XML::Parser's required for intltool, but we are running into a
situation in which gnome-vfs is *specifically asking* for XML::Parser and not
just intltool.  It's directly asking Perl if it has it, and folks are filing
bugs that are proving that we cannot be 100% sure between the time intltool
gets installed and gnome-vfs is emerged that XML::Parser is going to exist.  We
know we *should* have it, but should and actually have are two different
things.  It's like the hearsay rules in a court of law -- what one person hears
another say has much less weight than what that latter person actually said (we
get it from the horse's mouth, hay breath and all).

Just a 2cents worth - you could always check in unpack with something like:
perl -MXML::Parser -e 'print "$XML::Parser::VERSION"'
to make sure it comes back with a value and stop if not.

What's needed is a way of producing upgrade/update notes at the End of a
mass-update instead of per package.  Very few have the time or forethought to
log an entire emerge, and then check it's output for detailed update notes.

Instead an update log should be produced, and if there is a likelyhood that
something needs to be run, the user should be told...

'!!! IMPORTANT !!! You must read ~/emerge-update.DATESTAMP.txt it contains
vital post-update instructions for keeping your system working.'

Also, why doesn't emerging perl force a 'perl-clean modules' it looks like that
invocation is Supposed to fix exactly this problem, and re-emerging perl IS one
of the steps I tried after manually running cpan and being told it was already
installed...  I'd never have thought to look for an XML-Parser ebuild since
that should upgrade as well.

Unfortunately, that doesn't handle the case in which perl is being recompiled
before gnome-vfs while running an emerge --deep --update --newuse world.

I'm for that, but I'm also for adding dev-perl/XML-Parser in the dependencies
of gnome-vfs for reasons I stated above (gnome-vfs specifically checks for it,
the dependency-of-a-dependency is similar to heresay in legal circles, and it's
Perl -- assume the user is too lazy to run perl-cleaner, too impatient to run
perl-cleaner, and has the hubris to say the above).

"...assume the user is too lazy to run perl-cleaner, too impatient to run
perl-cleaner..."

Assume the is NOT to lazy to run perl-cleaner, and is NOT to impatient to run
perl-cleaner.  Assume that the user doesn't REALIZE he needs to run
perl-cleaner because the message has scrolled off the screen, or doesn't stand
out in the morass of text that continually spews out of emerge.  Assume that
the message that tells the user to perl-cleaner doesn't tell them what
option(s) they need to run it with.

Assume that's a lot more like the reality of 99.44% of the users who hit this
problem.

At least for my sys-apps/portage-2.1_pre7-r4, the ELOG features described in
/etc/make.conf.example do this quite well. They send me an email for every
warning or error message encountered while running some ebuild. So this feature
is coming, although it might not have reached stable status yet.

I believe that for me a dependency intltools-->XML-Parser would have cured my
"emerge --update world" problem, as it seems as if XML-Parser has not been
installed on my system (at least emerge did not report a previous module and
did not try to remove something after emerging XML-Parser).

True, this dependency does not solve the problem of Perl-Updates, but it may
solve an other problem. 

*** Bug 132233 has been marked as a duplicate of this bug. ***

If you have 5 Packages listed in emerge -pu world, do you bother scrolling up
for each of the compile stuff and look if there *could* be an info?

I once suggested that important messages about ebuilds should be output at the
*end* of *all* ebuilds, along with their package names.

Just to add to the long bug...

XML-Parser was never on my system at all. When I ran "emerge -pv XML-Parser"
(because I saw xkeyboard-config explode when XML::Parser.pm file was missing)
it was going to be a "n" new ebuild.

My system is was a pretty fresh install.

Hi sorry can you provide a summary of steps to solve/workaround the problem?
I've tried to do what I thought was the solution:
1.unmerge dev/perl/XML-Parser
2.emerge gnome-vfs-2.4.2-r1

even run perl-cleaner all
but again when I try to emerge gnome-vfs it fails with same sort of error


checking for XML::Parser... configure: error: XML::Parser perl module is
required for intltool

!!! Please attach the following file when filing a report to bugs.gentoo.org:

Ok, it worked now, I needed to update the intltool, otherwise it wouldn't work.
So my steps where,
1.unmerge dev/perl/XML-Parser
2.perl-cleaner all
3.emerge intltool (a new version was available and XMLParser was emerged)
4.emerge gnome-vfs
5.Restart doing what I was doing upgrade to x11 modular.


Thanks,
Pablo

I tracked the source of the error and I have noticed that the bug actually
reproduced each time dev-libs/expat is changed (upgraded/downgraded).
It gives :
# perl -e 'use XML::Parser'
Can't load
'/usr/lib/perl5/vendor_perl/5.8.8/i686-linux/auto/XML/Parser/Expat/Expat.so'

or something along this line.

The fix I have is to re-emerge dev-perl/XML-Parser after each and every time
dev-libs/expat is changed (upgraded/downgraded) :
# emerge XML-Parser
fixes it.

I believe there should be something put in the dev-libs/expat e-build to do
this.

Kind feedback welcome.

Could someone add "XML-Parser expat" to the summary of this bug so that the

Funny thing is that you only need to add XML-Parser as dependancy and it will
SOLVE every new instance. Again waiting almost two years... and it hit me again
today.

Yay, just hit this again on a fresh install.

What part about 'indirect dependencies are a Bad Thing' do you guys not get?

Come on people. If you consider how much time you are costing yourselves as
well as others, the price of fixing the solution is much smaller than the
problem itself.

It's things like this that give groups bad reps and make people not want to use
an OS / infrastructure.

Either that or are you hanging on to a glimmer of hope that maybe everything
bad will go away in perl6? Good luck.. perl's a good language but I doubt the
capability of its maintainers for coming out with a good product after the 5.x
interpreter series.

Over 2 years, the least you can do is resolve this.

Is perl a required dependency of the install CD? Does gentoo 2006 install an
old version of perl?

If not, then to blame the user for fscking up a perl install is probably unfair
in the extreme.

the following sequence of events will probably cause this error to occur...

Install gentoo
emerge xorg
emerge kde-base
emerge mozilla-firefox

(note that, at the time ie just before 2007 came out, I was installing the
latest (afaik) available gentoo).

imho it's pretty crap for a gentoo newbie (like me) to be left wondering what
the hell is going on, over what should be something nice and simple

I just run into this with gnome-base/gnome-vfs-2.18.1 during regular emerge
-avuDN world ... and nearly filed duplicate, because this did not show when
searching for "gnome-vfs" bugs

how can this be marked RESOLVED-INVALID when people keep running into this
again and again? if system is b0rken on regular update (or even on install? -

Because you didn't read the instructions provided by expat ebuild on upgrade,
as already noted in Comment #183. That's not a bug but a user failure.

Anyway, we are forcing people to recompile this now because of the horrible
flood of duplicate bugs.

17:07:13 <+CIA-15> drac * gentoo-x86/dev-perl/XML-Parser/ (3 files in 2 dirs):
17:07:13 <+CIA-15> Revision bump XML-Parser to avoid problems with expat
upgrade. No changes made to ebuild itself. 

So, even if you have already recompiled this, you'll be forced to do it again
on next emerge --sync, because people simply don't read whatever messages that
are provided, and don't search for duplicate bugs before filing one. Sorry.

I did emerge --system and couldn't notice the message..
Shouldn't these critical messages be appended to the end of the emerge output
via functions in ebuilds like einfo(), ewarn() and eerror()??

Maybe you should read /etc/make.conf.example and use the ELOG features that
have been available for just over 1 1/2 year now.

Yeah, thanks, I already use it. Apparently it doesn't do its job all that well.

Anyway, this is getting rather off topic. I've filed a feature request.
Jakub, feel free to reply at bug #188623

Yeah, fails to read the messages for you, you have to do it yourself. If you
can't be bothered to do even that, then kindly stop blaming portage for this.

So that we wouldn't generate 200 bugspams everytime someone fails to search for

Hi Jakub,

I notice you and others have repeatedly stressed that people should read the
output of emerge, so that they would notice that they have to run perl-cleaner
in order to prevent these problems.

However, as is posted by Anthony Youngman (#177) and some others, the error can
occur during one emerge run. If both perl and a package depending on
XML::Parser get updated during one "emerge -uDN world" command, then emerge
would fail on this bug, without it being "the users' fault".

I do understand that this is not a simple issue to solve, and I don't have a
simple suggestion for the solution. But I do feel the current perl-cleaner
workaround is not a sufficient solution, so I do think this issue deserves some
more thought.
I don't know if this bug (currently having status CLOSED INVALID) is the right
place for it, but I would like to humbly request that this ticket is taken into
account for a new feature in Portage, so that this can be solved in a decent
manner.

Kind regards,

Erik Logtenberg.

Oh please. don't blame the user to use ELOG if it is not enabled per default.
Those messages SHOULD be summerized at the end of the emerge process... i just
ran into this problem. Startet perl-cleaner, didn't do the job. Ops...
XML-Parser isn't even installed! Merged XML-Parser manually, but got another
error. At the moment i'm trying to run "revdep-rebuild -X".

well if you're not a fan of watching compilation lines all the day, you should
really know about this feature. About summary at the end of the merge, next
stable portage release will have it (I've been told it's in ~arch but I somehow
can't see it's effect), I don't know if it'll solve the breaks in the middle of
an update though.

ok, so you say that Gentoo does not allow non-interactive upgrades? - quite a
new for me ... until today I thought that user attention should be needed  when
changing profile (which may upgrade gcc etc) but not on regular emerge -u
something ...

btw, on _default config_ without redirecting stdout there is no way how to read
it (any other than to sit in front of monitor and really quickly read the
messages printed on screen) - but I see (bug 188623 comments) that it changes,
so you are aware of the problem ... how can you blame user if you know that
this really _is_ a problem?

I think the number of duplicates and interest in this bug speaks for itself. 
When this many people are affected by the same thing it's not right to blame
the user.  I think this bug needs to be reopened, and a better solution (even
that writing all the warnings at the end, because an emerge shouldn't ever fail
if everything is working properly, and it will in certain cases before the user
has a chance to run revdep-rebuild -X if certain combinations of packages are
pulled in at once)  What is it about Perl that makes it special anyway?  As
oppose to Python or Java?

I'm yet another victim of this bug on a big update world.
I don't understand which of these command I must launch : "revdep-rebuild -X"
or the perl cleaner script ? both ?

I guess you would not do anything bad running both; from my understanding, you
need to run the perl-cleaner only on certain setup, while you need to run
revdep-rebuild to repair all the packages broken by the removal of the old
version of libexpat (it is a good idea to run revdep-rebuild ocassionaly
anyway).

Btw, there may be some chain dependencies, e.g. what happended in my case -
I've rebuilt subversion but the svn command was still missing libexpat ... I
wondered what the hell is that, how it can be built depending on the library
which was not in the system while building, then it turned out that the problem
is with apr which is used by svn ...

Same problem here, but "revdep-rebuild" or "perl-cleaner" don't help. 
"emerge XML_parser" give the solution.

Well, I just installed Gentoo from liveCD 2007.7 (networkless, as other methods
failed), then set USE flags, run 
emerge --sync
emerge -DubN world
and the emerge failed.

I know, that Perl is root of (nearly) all evil, but isn't here some way to
manage the beast from destroing emerges for inoncent users?

(In reply to comment #247)

No, there's no way at all unless Bug 192319 is implemented. This bug is closed,
dead and nothing will happen here.
