bitbake: process: Add timeout to select call

2013-12-10T17:55:29+00:00

On some machines, a hang has been noticed where the system sits in the select call despite the task having completed. The exact reasons for this as unknown but adding a timeout unblocked the builds and resolved the hangs in question.

bitbake: lib: Clean up various file access syntax

2013-05-09T21:28:04+00:00

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

bitbake: process: Improve _logged_communicate buffering

2012-06-25T13:57:16+00:00

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 with some changes to flush upon exit, abstract the non blocking file descriptor setup and drop the buffer size parameter.
