Richard Purdie 8b1636763d bitbake: cache: Fix performance problem with large numbers of source files
Some companies are using large numbers of patch files in SRC_URI.
Rightly or wrongly that exposes a performance problem where the code
does not handle the large string manipulations in a way which works
efficienty in python.

This is a modified version of a patch from z00539568
<zhangyifan46@huawei.com153340508@qq.com which addresses the performance
problem. I modified it to use a more advanced regex, retain the "*" check
and cache the regex.

[YOCTO #13824]

Bitbake

BitBake is a generic task execution engine that allows shell and Python tasks to be run efficiently and in parallel while working within complex inter-task dependency constraints. One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software stacks using a task-oriented approach.

For information about Bitbake, see the OpenEmbedded website: http://www.openembedded.org/

Bitbake plain documentation can be found under the doc directory or its integrated html version at the Yocto Project website: http://yoctoproject.org/documentation

Contributing

Please refer to http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded for guidelines on how to submit patches, just note that the latter documentation is intended for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org) but in general main guidelines apply. Once the commit(s) have been created, the way to send the patch is through git-send-email. For example, to send the last commit (HEAD) on current branch, type:

git send-email -M -1 --to bitbake-devel@lists.openembedded.org
