Reduce size: CLEANUP_ON_SUCCESSFUL_BUILD

[philip]

My current size is 6.3 GB, which includes all of PHP 5 (5.0.0-5.3.6) and PHP 4.3.9.

We must create options to limit this size. The following code already exists within config.php:

// True will remove source/extract/build files on successful builds
// @todo not yet implemented
define ('CLEANUP_ON_SUCCESSFUL_BUILD', false);

I imagine it'll delete extracted directories, and probably the source files themselves. And a function that "knows which have built with success" could allow skipping the downloading/extracting/building stage for those, unless overridden. Think about it.

Conclusion: Delete stuff.

Sizes, in relation to the quote above:

352M downloads 4.6G extractions 607M bins 814M phpbuilds

Evaluating bins/ (only the cli builds) vs phpbuilds/ (all binaries plus man/lib/etc. as per --prefix) is one task, but extractions/ and downloads/ are the easy targets... especially extractions/.

Evaluation, ideas and thoughts:

• Extraction should happen before a single build. Currently ALL downloads are extracted before any builds take place :)
• Deletion of extracted directory should happen after the build, successful or not
• Deletion of download could take place after a build is known to be successful, not sure
• Performing all downloads before any builds is probably okay and should remain
• Keeping phpbuilds/ and not creating bins/ is probably the right thing to do. Other parts of code will need adjustment
