[PATCH 0/1] Fix perl re-execution issues

[Paul Eggleton]

Fix re-execution issues within perl.

Note: I identified that some references to /usr/include are still not
being substituted before or after this patch - you can see these by
doing "grep -rI '/usr/include' *" in WORKDIR after do_configure(). I do
not know enough about how we build perl to know if these are an issue or
not, thus I left them alone.


The following change since commit 4e1a8ed1ab7e7bd950e511c79ddfe072cb280a6e:

  bitbake.conf: Include abi_version.conf in a early stage (2012-04-16 12:51:50 +0100)

is available in the git repository at:

[PATCH 1/1] perl: fix re-execution of patch/configure

[Paul Eggleton]

The perl recipe's do_configure() does some manual sed replacements over
the entire WORKDIR. Fix the following issues with this:

* Skip patches, which fixes re-execution of do_patch after do_configure
  has run once
* Ensure that the replacement operation does nothing if do_configure is
  re-executed
* Avoid unnecessarily modifying /usr/include paths within documentation
  that will end up being packaged
* Fix a quoting issue in the expression used in the grep command that
  ended up causing files that did not contain .*\.h after /usr/include
  to be matched and modified.

The files modified during do_configure have been compared before and
after this patch to ensure there are no unexpected changes. Some
/usr/include paths that are not within documentation are no longer
being substituted however these are all within comments or scripts for
other Unix operating systems that are not applicable.

It would be much better to replace the 'grep -r' by 'find -type f ... |
xargs grep'.  'grep -r' is very bad because:

* '-r' is not standardized

* it can return symlinks which might point to read-only locations
  (e.g. patches/config.sh* are such links).  'sed -i' on such files
  can make the build fail.

er, that should be:

grep -rI "'/usr/include'" *
