Description Daniel Stone 2012-09-28 08:06:55 UTC 
'WARNING: The recipe is trying to install files into a shared area when those files already exist. Those files are:
   /home/daniels/collabora/yocto/build-i7/tmp/sysroots/x86_64-linux/usr/share/sgml/openjade-1.3.2/catalog'

It'd be really nice if this error message told us exactly which recipe caused the conflicting file to be installed.

This patch does not seem to work correctly:

Python 2.7.3

>>> sstate_search_cmd = "grep -rl /OE/jansa-test/shr-core/tmp-eglibc/pkgdata/armv7a-vfp-neon-oe-linux-gnueabi/runtime-reverse/vim-common /OE/jansa-test/shr-core/tmp-eglibc/sstate-control --exclude=master.list | sed -e 's:^.*/::' -e 's:\.populate-sysroot::'"
>>> cmd_array = sstate_search_cmd.split(' ')
>>> search_output = subprocess.Popen(cmd_array, stdout=subprocess.PIPE).communicate()[0]
grep: |: No such file or directory
grep: sed: No such file or directory

So it never shows any match.

Adding shell=True makes it work
>>> search_output = subprocess.Popen(sstate_search_cmd, shell=True, stdout=subprocess.PIPE).communicate()[0]
>>> print search_output
manifest-armv7a-vfp-neon-gvim.package
manifest-armv7a-vfp-neon-vim-tiny.package
manifest-armv7a-vfp-neon-vim.package

But still isn't 100% reliable, I guess it's caused by some other package being removed from sstate while grep is already running.
>>> search_output = subprocess.Popen(sstate_search_cmd, shell=True, stdout=subprocess.PIPE).communicate()[0]
grep: /OE/jansa-test/shr-core/tmp-eglibc/sstate-control/manifest-armv7a-vfp-neon-systemtap.package: No such file or directory
Comment 3 Saul Wold 2012-12-03 23:08:13 UTC 
There's a patch on the list from Enrico also, but it addresses something a little different.

http://lists.linuxtogo.org/pipermail/openembedded-core/2012-November/031850.html

It's been pending for sometime, I will push RP on this patch

I am testing with your suggestion
