bitbake: bitbake: Add initial pass of SPDX license headers to source code

2019-06-19T17:04:01+00:00

This adds the SPDX-License-Identifier license headers to the majority of our source files to make it clearer exactly which license files are under. The bulk of the files are under GPL v2.0 with one found to be under V2.0 or later, some under MIT and some have dual license. There are some files which are potentially harder to classify where we've imported upstream code and those can be handled specifically in later commits. The COPYING file is replaced with LICENSE.X files which contain the full license texts.

bitbake: bitbake:process: flush stderr/stdout to log

2017-06-14T13:54:24+00:00

When a process terminates, some messages may still remain in stdout or stderr and do not make it into the log file. In addition, the messages that do make it to the log file may end up in the log file in incorrect order. This patch flushes all messages into the log file after the process terminates. Some additional log flushing is also needed to keep the various messages showing up in the log file in proper order.

bitbake: process: stop bb.process.communicate mixing bytes and str return types

2017-03-01T11:16:07+00:00

Python3 regards b"" as False so it is not being converted to a string by d0f904d407f57998419bd9c305ce53e5eaa36b24. This confusingly causes three different potential types for each member of the returned tuple. Let's just assume that everything that's not None is a bytes object and convert it to a string.

bitbake: bitbake: Convert to python 3

2016-06-02T07:24:02+00:00

Various misc changes to convert bitbake to python3 which don't warrant separation into separate commits. (Bitbake rev: d0f904d407f57998419bd9c305ce53e5eaa36b24) Signed-off-by: Richard Purdie

bitbake: Fix default function parameter assignment to a list

2015-08-19T17:05:44+00:00

With python you should not assign a list as the default value of a function parameter - because a list is mutable, the result will be that the first time a value is passed it will actually modify the default.

bitbake: lib/bb/process: check output of select() before reading extrafiles

2015-07-16T14:09:26+00:00

We're calling select() to find the fds that have data available, so we really ought to check the return to see if the extra file is in there before trying to read from it. This is part of the fix for the performance regression that this code introduced (5-10 minutes extra in a reasonable size OE build); the rest is down to an issue in the way that pseudo currently handles FIFOs and will need to be addressed there, see: https://bugzilla.yoctoproject.org/show_bug.cgi?id=7993 Solution suggested by Richard Purdie (Bitbake rev: 3e2db8d7eaa0f14813213d1c95d3ee9efd97dc9d) Signed-off-by: Paul Eggleton Signed-off-by: Richard Purdie

bitbake: lib/bb: set up infrastructure for shell message functions

2015-07-12T21:50:40+00:00

Create a fifo under ${T} for each running task that can be used by the task to send events back to BitBake. The purpose of this is to allow OpenEmbedded's logging.bbclass (which provides shell function equivalents for bb.warn(), bb.note() etc.) to have those functions trigger the appropriate events within BitBake so that messages are shown through the BitBake UI rather than just in the task log; to do that we just call the python functions. Part of the fix for [YOCTO #5275]. (Bitbake rev: bae330a1f8a59a912eca71177b3c6ba7c92a2f38) Signed-off-by: Paul Eggleton Signed-off-by: Richard Purdie

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
