Attached: * log.0.txt: output log * solution.tar.gz: a proposed starting solution which in our case did solved the issue while doing 'do_dumpdata_create_diff_gz' for 'udev' package. Still the same issue with the 'linux-qoriq-sdk' is still reproduced at the 'do_dumpdata_create_diff_gz'. 35405 1 1410 valentin.cobelea 2013-08-06 09:29:23 +0000 Created attachment 1410 starting solution (fixed udev package issue) 35406 2 valentin.cobelea 2013-08-06 09:37:56 +0000 Additional information: -the build was based on the 'meta-fsl-ppc' layer; -image type: 'core-image-minimal'; Also since the 'diff' has no mechanism to not follow symlinks, we need to have this covered in the 'archiver.bbclass' (this is what the proposed solution does). There are plenty of other packages, with synlinks inside/after build, that might fail while doing the 'do_dumpdata_create_diff_gz'. Also the 'subprocess.call()' is not bullet proof, we should use 'subprocess.Popen()' in order to have more control over the spawned process (http://docs.python.org/2/library/subprocess.html#popen-constructor). We could trigger 'terminate' to it, in case it goes on indefinitely. 35419 3 valentin.cobelea 2013-08-06 11:23:13 +0000 As an alternative solution for getting all the "folder" symlink is: import os for root, dirs, files in os.walk('./',followlinks=True): if (os.path.islink(root)): #add it to the exclude list This could replace the whole 'get_sym_links_list()' method from the attached patch. 35423 4 1414 valentin.cobelea 2013-08-06 13:48:41 +0000 Created attachment 1414 only recursive symlinks are added to the Refined version of the proposed solution is attached here ('recursive-solution.tar.gz'). Now only the recursive symlinks are added to the exclusion file used by DIFF. 35440 5 sgw 2013-08-07 02:17:15 +0000 If you have a solution, please accept this bug and provide a solution to the OE-Core list as a proper patch. 35446 6 valentin.cobelea 2013-08-07 07:15:02 +0000 There are only the proposed solutions (both attached), but these are only starting points for the solution I am hopping to see from anyone in charge of the 'archiver.bbclass'. Even with what I made the problem still replicates but each time for another package, this would be why I consider my solutions only a part of the real deal and a starting point. 36124 7 liezhi.yang 2013-08-31 02:08:28 +0000 (In reply to comment #6) > There are only the proposed solutions (both attached), but these are only > starting points for the solution I am hopping to see from anyone in charge > of the 'archiver.bbclass'. > Even with what I made the problem still replicates but each time for another > package, this would be why I consider my solutions only a part of the real > deal and a starting point.

We consider that there should be several test runs (several full builds with the archiver mode enabled for "patched" and "tar" p- as you already tried) in order to reproduce this issue which makes build not completing. My patches addressed the recursive symlinks (the last one is directly for this, from 2013-08-06 13:48 UTC) which are generating the issue, by removing each of them from the list.

The idea behind the algorithm there is that I am excluding the recursive symlinks by crating a list of folders and another one of symlinks. Those that are recursive are not added to the list, hence the issue will not occur. Also, please run full builds, not for 'udev' only, the issue occurs for any package (usually system related, like udev is) that has recursive symlinks. If you consider that there is a better solution to this issue, please apply it, my attached patches were just proposed solutions.

Hi Valentin, After more investigation, many other problems are found, so I'd like to refactor the 4 classes in 1.6, please see 5113, move it to 1.6. 36526 25 valentin.cobelea 2013-09-11 09:38:02 +0000 (In reply to comment #24) > (In reply to comment #23) > > (In reply to comment #20) > > > > Yes, I can help you with testing the patch(s), let me know when you have a > > "final version" - that address to all things - for it so that I can start > > some builds. > > > > BR, > > Valentin > > > > > (In reply to comment #18) > > > > (In reply to comment #17) > > > > > (In reply to comment #16) > > > > > Thank you very much. > > > > > > > > > > Valentin > > > > > > > > Hi Valentin, I have added your signed-off and sent oe-core mailing list: > > > > > > > > http://lists.openembedded.org/pipermail/openembedded-core/2013-September/ > > > > 083759.html > > > > > > > > Thanks for the contribution:-) > > > > > > Hi Valentin, > > > > > > I've added a new patch, it would be great it you can help me to test it. > > Hi Valentin, > > After more investigation, many other problems are found, so I'd like to > refactor the 4 classes in 1.6, please see 5113, move it to 1.6. Hi, Thank you for all the investigation, it makes clear now why the issue was occurring on a random basis. I am fine with the postpone of the class refactor to v1.6.
