| 2 | ======= |
| 3 | |
| 4 | BitBake is a generic task execution engine that allows shell and Python tasks to be run |
| 5 | efficiently and in parallel while working within complex inter-task dependency constraints. |
| 6 | One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software |
| 7 | stacks using a task-oriented approach. |

| Brad Bishop | d7bf8c1 | 2018-02-25 22:55:05 -0500 | [diff] [blame] | 21 | for guidelines on how to submit patches, just note that the latter documentation is intended |
| 22 | for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org) |
| 23 | but in general main guidelines apply. Once the commit(s) have been created, the way to send |
| 24 | the patch is through git-send-email. For example, to send the last commit (HEAD) on current |
| 25 | branch, type: |
| 26 | |
| 27 | git send-email -M -1 --to bitbake-devel@lists.openembedded.org |

| 37 | Testing: |
| 38 | |
| 39 | Bitbake has a testsuite located in lib/bb/tests/ whichs aim to try and prevent regressions. |
| 40 | You can run this with "bitbake-selftest". In particular the fetcher is well covered since |
| 41 | it has so many corner cases. The datastore has many tests too. Testing with the testsuite is |
| 42 | recommended before submitting patches, particularly to the fetcher and datastore. We also |
| 43 | appreciate new test cases and may require them for more obscure issues. |
