Bugzilla Bug 19193

After i rsynced my portage today with a server, i wanted to update libao since
there was an update for it. So i did an "emerge libao" which fetched the update.
Than just after the unpacking finished, the ebuild failed patching the source
somehow. Luckily emerge did manage to throw some output in the temporary compile
directory, which i'll put in as attachment.

Reproducible: Always
Steps to Reproduce:
1. (optional) emerge rsync
2. emerge -p libao
3. emerge libao

Actual Results:  
1. The usual emerge sync data flows over the screen
2. Emerge tells me that it wants to install libao-0.8.3-r1
3. Emerge downloads libao and doesn't download any patches. After unpacking
libao, patching is attempted but fails probably due to a ?missing patch? .

Expected Results:  
Just should have downloaded the data, unpacked libao and patch it afterwards.
After that, compiling & installing should follow.

failed patching for emerge libao-0.8.3-r1

Well, the patch doesn't actually get downloaded, it is kept in the FILESDIR, so
if you don't mind, go ahead and rsync one more time, in case for some reason
the patch got commited too late to get propagated at the same time as the
patch, and then run:

> md5sum /usr/portage/media-libs/libao/files/libao-0.8.3-r1.patch 

I get the following md5sum, and patching goes through without a hitch:

5f642fcbb8941a2f070cce0697f218fd


However, judging from the output, it looks that the patch is there, but perhaps
corrupt, or for some reason S is not being defined properly.

Please try removing the patch if it does exist and rsyncing again.

I get the same as Jochem. MD5SUM matched. Deleted the patch,synced and emerge failed again.

i haw updatedb and locate libao and delited all whit the name libao and emerge rsunc i get the error aneyway

Ah, I'm sorry guys, I see the problem. The ~x86 version of this package works
fine. The problem is that in the 0.8.3 version it tries to find the patch as
${P}-${PR} .. obviously there is no revision for 0.8.3

The second problem is that there is no patch for this version of libao.
I've fixed both problems and cleaned up the ebuild in general. Let me know if
you have any other problems.

*** Bug 19242 has been marked as a duplicate of this bug. ***

there is still a problem with the patch, it tries to apply to an absolute path

/var/tmp/portage/libao-0.8.3-r1/work/libao-0.8.3/src/plugins/alsa09/ao_alsa09.c

but if you have your portage tmp dir somewhere else it fails, so please change the path to

src/plugins/alsa09/ao_alsa09.c
