meta/lib/oe/utils.py: properly implement both_contain()

2015-03-09T16:00:14+00:00

oe.utils.both_contain() just does a find() on the value
rather than splitting the value and then looking in the
list of split items. The result is that if you add a
feature to MACHINE_FEATURES that itself has a substring
that matches one of the values looked for when building
COMBINED_FEATURES, you end up with an incomprehensible
error (here with "ext2i" in MACHINE_FEATURES):

ERROR: Nothing RPROVIDES 'packagegroup-base-ext2'
(but /home/balister/src/oe-core/oe-core/meta/recipes-core/
/packagegroups/packagegroup-base.bb RDEPENDS on or otherwise requires it)

Fix [YOCTO #6888].

image-buildinfo.bbclass: new class, writes build information to image

2014-11-09T10:17:04+00:00

Writes build information to target filesystem on /etc/build such as enabled
layers, their current status and commit.

squashspaces was moved to oe/utils.py to make it available to different classes
and avoid code duplication.

lib/oe/utils: Make multiprocess_exec() return anything

2014-08-29T22:42:57+00:00

The variable "results" was accidentally used for multiple different
things at the same time, which unintentionally discarded anything that
was supposed to be returned from the function...

lib/oe/utils: Add utils function for multiprocess execution

2014-08-23T08:29:49+00:00

Our usage of multitprocessing is problematic. In particular, there is a bug
in python 2.7 multiprocessing where signals are not handled until command
completion instead of immediately.

This factors the multiprocess code into a function which is enhanced with
a workaround to ensure immediate signal handling and also better SIGINT
handling which should happen in the parent, not the children to ensure
clean exits. The workaround for the signals is being added to the core
bb.utils function so it can benefit all users.

package_manager is then converted to use the new code.

Globally replace oe.utils.contains to bb.utils.contains

2014-04-25T16:10:58+00:00

BitBake has the exact same code as oe.utils.contains so there's no
reason to duplicate it. We now rely on the bb.utils.contains code for
metadata.

utils: Add a cpu_count wrapper function

2014-01-27T22:08:58+00:00

Add a cpu_count wrapper function (useful from annonymous python where
the import would be trickier).

utils: add trim_version() function

2013-05-30T19:51:27+00:00

Add a helper function that returns just the first  of ,
split by periods.  For example, trim_version("1.2.3", 2) will return "1.2".

This should help reduce the spread of numerous copies of this idea across
classes and recipes.

class/lib: Fix up various file access methods

2013-05-09T21:25:31+00:00

There are various bits of cruft that have built up around our file accesses. This patch
cleans some of them up, specifically:

 * Remove pointless "from __builtin__ import file"
 * Use open(), not file()
 * Wrap file usage in a with container to ensure files are closed
 * Add missing .close() calls in some cases

classes/lib: Fix getcmdstatus breakage

2013-05-09T15:05:02+00:00

I mistakenly thought subprocess had getcmdstatus in python 2. It doesn't so lets
add a wrapper and have this work in both worlds.
