* bitbake: lib: Use modern expcetion syntaxRichard Purdie2013-05-091-1/+1

* bitbake: lib: Clean up various file access syntaxRichard Purdie2013-05-091-0/+4
| | | | | | | | | | | | | Python 3 is stricter about how files are accessed. Specficially: * Use open(), not file() * Use binary mode for binary files (when checksumming) * Use with statements to ensure files get closed * Add missing file close statements (Bitbake rev: 9f08b901375ba640f47596f1bcf43f98a931550f) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* bitbake: process: Improve _logged_communicate bufferingRichard Purdie2012-06-251-13/+33
| | | | | | | | | | | | | | | | | | | | | | | | | There are two problems with the _logged_communicate that are both caused as a result of buffering I/O issues: 1) log truncation when python fails 2) While a bitbake task is running it is impossible to see what is going on if it is only writing a small incremental log that is smaller than the buffer, or you get only a partial log, up until the task exists. It is worse in the case that stderr and stdout are separate file handles, because previous code blocks on the read of stdout and then stderr, serially. The right approach is simply to use select() to determine if there is data available and also flush the log before exiting. This is based on a patch from Jason Wessel <jason.wessel@windriver.com> with some changes to flush upon exit, abstract the non blocking file descriptor setup and drop the buffer size parameter.

* Fix PWD issue with new exec_func_shellChris Larson2011-01-041-2/+0
| | | | | | | | | | | | | | | | The previous attempt was incorrect. The issue isn't that subprocess fails to set PWD, it's that PWD is in the metadata, inherited from the environment, and is re-exported, overwriting the actual accurate one in the shell environment with the old one from the metadata. So, ensure that PWD in the metadata is not exported. We can ditch this when the environment handling is reworked (e.g. poky's commit to do so).
