meta/lib+scripts: Convert to SPDX license headers

2019-05-09T15:31:55+00:00

This adds SPDX license headers in place of the wide assortment of things currently in our script headers. We default to GPL-2.0-only except for the oeqa code where it was clearly submitted and marked as MIT on the most part or some scripts which had the "or later" GPL versioning. The patch also drops other obsolete bits of file headers where they were encoountered such as editor modelines, obsolete maintainer information or the phrase "All rights reserved" which is now obsolete and not required in copyright headers (in this case its actually confusing for licensing as all rights were not reserved). More work is needed for OE-Core but this takes care of the bulk of the scripts and meta/lib directories. The top level LICENSE files are tweaked to match the new structure and the SPDX naming.

classes/sstate: Update output hash

2019-01-22T14:35:58+00:00

Updates the output hash calculation for determining if tasks are equivalent. The new algorithm does the following based on feedback: 1) The output hash function was moved to the OE library. 2) All files are printed in a single line tabular format 3) Prints the file type and mode in a user-friendly ls-like format 4) Includes the file owner and group (by name, not ID). These are only included if the task is run under pseudo since that is the only time they can be consistently determined. 5) File size is included for regular files (From OE-Core rev: 4bd297dfe92851f3b44f6b5560bac9d8f9ccf9f2) Signed-off-by: Joshua Watt Signed-off-by: Richard Purdie

lib/sstatesig: Update to longer sha256 hash length

Update the code to match the recent switch to sha256 hashes (From OE-Core rev: 910a8f3e8e350ff5d316faf5e07fb40c6c51f45e) Signed-off-by: Richard Purdie

sstate: Implement hash equivalence sstate

2019-01-08T11:16:44+00:00

Converts sstate so that it can use a hash equivalence server to determine if a task really needs to be rebuilt, or if it can be restored from a different (equivalent) sstate object. The unique hashes are cached persistently using persist_data. This has a number of advantages: 1) Unique hashes can be cached between invocations of bitbake to prevent needing to contact the server every time (which is slow) 2) The value of each tasks unique hash can easily be synchronized between different threads, which will be useful if bitbake is updated to do on the fly task re-hashing.

multiconfig: Enable multiconfig dependencies on oe-core

2018-08-01T09:07:22+00:00

This patch enables multiconfig dependencies (mcdepends) to be used on recipes using the following format: task[mcdepends] = "multiconfig:FROM-MC:TO-MC:PN:task-to-depend-on" For the sake of simplicity consider the following example: Assuming we have set up multiconfig builds, one for qemux86 and one for qemuarm, named x86 and arm respectively. Adding the following line to an image recipe (core-image-sato): do_image[mcdepends] = "multiconfig:x86:arm:core-image-minimal:do_rootfs" Would state that core-image-sato:do_image from x86 will depend on core-image-minimal:do_rootfs from arm so it can be executed. This patch makes modifications to bitbake.conf to enable mcdepends, and to sstatesig and staging.bbclass to avoid conflicts between packages from different multiconfigs.

lib/oe/sstatesig: Fix task mappings from multilib<->non-multilib contexts

2018-07-02T20:37:47+00:00

If we're in a multilib context already and want a non-multilib context this function returned incorrect values. Try and retain optimisations for the common case not needing to request a datastore but allow the different multilib/non-multilib combinations to work too. This fixes bugs where rootfs generation of a multilib image would write into incorrect locations, or be unable to find sstate manifest files due to incorrect data stores being used to expand data.

The special string "*" on the left hand side of the dependency specification matches all recipes except the one on the right hand side. (From OE-Core rev: 526855f6573317ced913f39e878beac1d5d294de) Signed-off-by: Joshua Watt Signed-off-by: Richard Purdie
