2aeb91cdb3 bitbake: bitbake-setup: Rename bb-layers-relative to bb-layers-file-relative
The difference between bb-layers and bb-layers-relative is unclear as both
are relative paths. Rename one to "file-relative" which makes it clear it
is relative to the current file, without becomming a long name.

https://lists.openembedded.org/g/bitbake-devel/message/18296

Based on a patch from Alexander Kanavin <alex@linutronix.de> but
with different naming.

516039e609 bitbake: bitbake-setup: replace {THISDIR} token with a keyword: bb-layers-relative
{THISDIR} is a special value token that can be used in the list of enabled
layers to specify the layer location relative to the confguration file:
https://git.openembedded.org/bitbake/commit/?id=b3153be29de8b8570b0c184369bd41f4c646cf92

This replaces the token with an explicit separate keyword for such layers:
so that special processing to determine the final value can be avoided, and
the feature can be formalized in the json schema:

instead of
   "bb-layers": [
        "{THISDIR}/meta-my-project"
    ]

this allows
   "bb-layers-relative": [
        "meta-my-project"

Going forward I think we should strive to avoid any further special value tokens.

9780ec24d0 bitbake: bitbake-setup: capture revisions while checking out layers
When initializing a build setup from a conf.json that only sets 'rev'
to a tag or branch, the actual revision would not be captured or
logged.

To capture the current layer state after an 'init' or 'update', the
checkout_layers function is extended to store the revision the
bb.fetch.Fetch pulled, and write that information into a
sources-fixed-revisions.json file. This file can then be fed back into
bitbake-setup init as: --sources-overrides

This new 'sources-fixed-revisions.json' is written during 'update_build' and
stored alongside the 'config-upstream.json' in the config dir. And put
with the later under version control by calling 'commit_config" after
'update_build'.

The use of 'deepcopy' is necessary to not modify the original input
data - which python passes around as reference.

13b7a749ec bitbake: bitbake-setup: tests: move duplicate code into 'check_setupdir_files'
All places that called into 'check_setupdir_files' did the same
preparation step to load the upstream-config.json and then pass it
into the function.

Since the 'setuppath' is already passed into the function, and the
name and relative location of the upstream-config.json is fixed,
constructing the file path and loading the json could be done in the
function.

De-duplicate code by loading the json inside the function instead.

ec569c235d bitbake: toaster: support bitbake-setup
This adds support for the new bitbake-setup:
      * Maintain backwards compatibility for poky-classic releases
      * Assume bitbake-setup for all releases 'master' and forward
      * When no ".templateconf" assume Poky and not OE
      * Generate and use "init-build-env" script instead of 'oe-init-build-env'
        directly, but "cd" to the clone and not the local installation.
      * Include "bblayers.conf" because "cookerdata.py" now explicitly
        required it, and let it be over-ridden by the usual "toaster-bblayers.conf".
      * Force the value "TOPDIR" in "toaster.conf" to the local project's directory.

    Normally "cookerdata.py" sets TOPDIR from getcwd(), but somehow in bitbake-setup
    mode the CWD at this point has become ".../layers/openembedded-core", so
    "bitbake.conf and all other files cannot be found. This non-obvious problem was
    hard to discover. Until this is understood, the forced value will make things work.

5d7abe740e bitbake: bitbake-setup: rename 'build' -> 'setup'
After a terminology review by Antonin we brainstormed
something less confusing than 'build' and 'build directory'
for the place where bitbake-setup clones layers and
creates a *bitbake* build directory in. People are bound
to get these two confused and mix them up, and 'setup' is
much more distinct and aligns nicely with 'bitbake-setup'.
It's also not claimed by anything else in OE/Yocto.

So before:

top-dir -> build-dir (can be several) -> bitbake build dir, layer dir, config dir

Now:

top-dir -> setup-dir (can be several) -> bitbake build dir, layer dir, config dir

This also updates the respective command line options, I understand it's
a breaking change, but as before the tweaks are simple and we need to get the
terminology right for the users, and now is the time to do it.

7320e59aec bitbake: bitbake-setup: commandline: use subsubparser for settings {list,set,unset}
Previously the sub-command 'settings' would take any number of
arguments and then silently do nothing if the number wasn't three.

The help text was also not clear about this, marking the positionals
separately as optional:

usage: bitbake-setup settings [-h] [--global] [--unset UNSET UNSET] [-l] [section] [key] [value]

The '--unset SECTION SETTING' also did not  integrate too well, as it
had its own positional arguments for section+setting.

For a bit more consistency and a explorable help, a sub-subparser is
added, that provides the commands:
  bitbake-setup settings list
  bitbake-setup settings set foo bar baz
  bitbake-setup settings unset foo bar
with a '--global' that is added from a stand-alone parent parser, so
that it shows up in all sub-command help texts.

The new help text now reads:
usage: bitbake-setup settings [-h] [--global] {list,set,unset} ...

and the respective sub commands:
usage: bitbake-setup settings list [-h] [--global]
usage: bitbake-setup settings set [-h] [--global] <section> <setting> <value>
usage: bitbake-setup settings unset [-h] [--global] <section> <setting>

cd4fe0aada bitbake: bitbake-setup: further rework the settings handling
After some further feedback, additional changes are made:

1. 'setting' command is renamed to 'settings' to better reflect
that it is an interface to various ways of managing settings.

2. This command now has a -l/--list option to list all settings
with their values (same as 'git config -l').

3. A new level of settings (built-in defaults) is added,
and used as a last resort after command line options, top dir
settings file and global settings file.

4. This means bitbake-setup does not have to write and use a
global settings file, and it no longer does so when initializing
a build, avoiding default 'pollution' of ~/.config/bitbake-setup/
which can be problematic or unwelcome.

A global settings file is still created if a setting is explicitly
requested to be placed into it.

5. 'install-global-settins' is removed as the use case for it
(tweak default settings before using them to initialize a build)
can be achieved by setting the settings individually.

5. Similarly, a top dir settings file is no longer created by default
and only appears if a setting needs to be written into it.

6. Default dl-dir is again created inside a top directory and not
in ~/.cache/ to make default builds fully contained in the top
directory (which was also asked about).

401e7b6a10 bitbake: bitbake-setup: rework the settings handling
This is the outcome of various discussions, suggestions and pull
requests on github.

What has specifically changed?

1. The sources for the settings are no longer separated, but are stacked and given priorities,
from highest to lowest:

    a. '--setting section key value' on the command line

    b. a settings file in the top directory

    c. a global settings file in ~/.config/bitbake-setup/ (or in a file pointed to by --global-settings)

Any setting can be in any of these three locations (other than top dir name and prefix which do not
make sense in the settings file in the top directory).

2. A global settings file must contain all of the needed settings, while a settings file
in the top directory can be empty (and this is how they are written out if they do not exist).

Specifically, both dl-dir and registry settings have been relocated to the global file,
and dl-dir defaults to ~/.cache/bitbake-setup/downloads, rather than somewhere in top dir.

3. The file name for both global and top dir settings is now 'settings.conf'.

4. --top-dir-prefix and --top-dir-name options have been removed and superseded by
a generic, universal --setting option.

5. 'install-settings' command has been removed, as it is no longer does anything useful,
and is superseded by the 'setting' command (see below).

'install-global-settings' has been retained, to be able to have a set of global defaults
that can be changed without initializing a build.

6. 'change-setting', 'change-global-setting' and 'install-settings' have all been replaced
by a single 'setting' command that mimics 'git config' in its parameters:

    a. Changing a setting: bitbake-setup setting [--global] default dl-dir /path/to/downloads

    b. Removing a setting: bitbake-setup setting [--global] --unset default dl-dir

bitbake-setup conf.json can be purely template driven, to setup older
yocto LTS (e.g. scarthgap) based layer-collections - where fragment
support was not yet present in oe-core+bitbake.

Add a configuration for that scenario and add it to the test routine.

60d995ccc4 bitbake: bitbake-setup: support adding environment-passthroughs to the init-build-env
This patch adds support for extending the BB_ENV_PASSTHROUGH_ADDITIONS
environment variable from within the `init-build-env` wrapper script -
generated by either oe-core's oe-setup-build, or by `bitbake-setup` -
based on per-configuration JSON settings.

This enables CI workflows to inject environment-specific data - such
as build number, host, build type, or credentials required to fetch
from certain SRC_URIs - which cannot be captured via configuration
fragments alone. These variables are now handled early in the setup
process and exported directly into the build environment.

Example:

  "bb-env-passthrough-additions": [
      "ACME_DIR",
      "ARTIFACTORY_TOKEN",
      "ARTIFACTORY_USERNAME",
      "GITHUB_TOKEN",
      "GITHUB_PROTOCOL",
      "KEY"
  ]
  <snip>

the resulting 'init-build-env' would then be:
  # environment passthrough added by bitbake-setup
  export BB_ENV_PASSTHROUGH_ADDITIONS=" \
  $BB_ENV_PASSTHROUGH_ADDITIONS \
  ACME_DIR \
  ARTIFACTORY_TOKEN \
  ARTIFACTORY_USERNAME \
  GITHUB_TOKEN \
  GITHUB_PROTOCOL \
  KEY"
  # init-build-env wrapper created by bitbake-setup
  . /tmp/acme_master-acme-distro_acme-machine_bang/layers/openembedded-core/oe-init-build-env /tmp/bitbake-setup/gs/acme_master-acme-distro_acme-machine_bang/build

39af683c76 bitbake: bitbake-setup: add support for skipping a fragment selection
In autobuilder testing a use case arised where
- the available choices in configuration file for choosing a machine are incomplete
- putting every possible machine choice into that configuration is undesirable/not possible
- autobuilder code can write a machine selection into the bitbake config
after the fact.

So this --skip-selection option is intended for advanced users that know what they're doing
and is generally not recommended as it requires manually tweaking the bitbake config to
make it usable.

28055e0c0d bitbake: bitbake: registry: make a separate configuration for poky with sstate mirror
Using sstate mirror places much higher requirements on both network robustness
and network bandwidth than just fetching source code. When the network doesn't meet
those, the user experience can be very frustrating as errors can be cryptic and
intermittent, or bitbake would just seemingly do nothing for a long time.

Let's make sstate an opt-in, and provide a caution for using it. When it does
work, it works wonderfully and does accelerate builds significantly.

3fe3e0ba1f bitbake: bitbake-setup: clarify that default answer to prompts is no
It is common practice to put the default choice in upper case for
yes/no interactive prompts, so that when people just hit enter, they
know what they are getting.  An example that linux users are probably
familiar with is "sensors-detect" from the "lm-sensors" package.

Unify all the prompts to be the same and indicate that the default
answer from hitting enter is a no with an upper case N.  No functional
changes.

20f58af1b3 bitbake: bitbake-setup: allow using {THISDIR}/my-layer
This implement the ability to use "{THISDIR}/my-layer" in the
"bb-layers" list. "{THISDIR}" is remplaced by the directory containing
the configuration file.

In small projects, we try to keep the setup a simple as possible: a
single git repo containing both the build confguration (e.g.
a bitbake-setup configuration file) and the meta layer with project
recipes/machine/distro.

This change allows this kind of setup:
├── meta-my-project/ # the project layer
└── my-project.conf.json   # the bb-setup configuration file

by writing, in my-project.conf.json:
  "bitbake-setup": {
    "configurations": [{
      "bb-layers": [
        "{THISDIR}/meta-my-project"

Note: in this case meta-my-project is not present as a "source", so, not
handled by bb-setup update/status. It is expected of the user to handle
this on their own (is our case, a simple git workflow).

0c37775349 bitbake: bitbake-setup: dash support for init-build-env script
Being minimalist, dash does not support the (non-POSIX) feature of
passing an argument while sourcing a script. Like in
  . <some path>/oe-init-build-env <build dir>

With dash, one must use:
  set <build dir>       # puts <build dir> in $1
  cd <some path>
  . ./oe-init-build-env # can only be called from its directory in dash

To do this:
* Instead of a symlink to oe-init-build-env, keep a symlink to the
  directory containing it (called "oe-init-build-env-dir")
* Generate a init-build-env script that dash can source using the above
  snippet.

1a55c45617 bitbake: bitbake-setup: add support for specifying branches in repo checkouts
Previously bitbake-setup was checking out 'detached commits' using
fetcher's nobranch feature, as that is the only option when only a revision is in the config.

Branches are optional, but beneficial, as

- checkout directory will be on a branch, making it easier for users
to understand where they are if they need to make changes (also
bitbake will print branch information instead of saying 'HEAD:sha').

- supply chain security! Enforcing a branch means any specified revision
has to be on it, and no one can sneak in (accidentally or deliberately!)
some dangling commit, or something from their private branch in the same repo.

... (output from install-buildtools script)
======

It also detects when buildtools are already installed, and will direct
users what to do:
======

Loading settings from /home/alex/bitbake-builds/bitbake-setup.conf

Buildtools are already installed in /home/alex/bitbake-builds/yocto-master-testing/buildtools.
If you wish to use them, you need to source the the environment setup script e.g.
$ . /home/alex/bitbake-builds/yocto-master-testing/buildtools/environment-setup-x86_64-pokysdk-linux
You can also re-run bitbake-setup install-buildtools with --force option to force a reinstallation

a66c929a6a bitbake: bitbake-setup: add tests to bitbake-selftest
Run like this:

alex@Zen2:/srv/work/alex/bitbake$ bin/bitbake-selftest -v bb.tests.setup
test_setup (bb.tests.setup.BitbakeSetupTest.test_setup) ... ok

----------------------------------------------------------------------
Ran 1 test in 9.223s

OK

The test does a basic run-through of init, then status/update
on an unchanged configuration, then status/update on a
configuration changed via new commits to the test layer,
then status/update on configuration changed via the top
level json config file.

Note that nothing whatsoever is fetched from the network;
the test relies entirely on synthetic data contained inside
itself, including minimal stubs for oe-setup-build and
bitbake-config-build. This data is used to create temporary
git repositories then clone them via local filesystem URIs.

Later on this can be supplemented by an oe-selftest that
tests bitbake-setup against real config files in the
official configuration repository and real layers,
templates and fragments.

b05d3c8a31 bitbake: bitbake-setup: add the initial implementation
Preamble
========

The latest iteration of this patchset is available at
https://github.com/kanavin/bitbake
I recommend taking the patches from there to ensure that
you are not trying out outdated code.

For the rationale and design guidelines please see this message:
https://lists.openembedded.org/g/openembedded-architecture/message/1913

Left out for now but will be done later:

- official configuration repository

- documentation

Amble *scratch* HOWTO
=====================

1. If you don't know where to start, run 'bitbake-setup init'.

Bitbake-setup will ask a few questions about available configuration choices and set up a build.

Note: 'init' sub-command can also take a path or a URL with a configuration file directly.
You can see how those files look like here:
https://github.com/kanavin/bitbake-setup-configurations

2. You can then source the bitbake environment and run bitbake to perform builds as usual:

$ . /home/alex/bitbake-builds/yocto-master-options-poky-distro_poky-machine_qemux86-64/build/init-build-env

Also, subsequent status/update commands will not require a separate --build-dir argument telling
bitbake-setup where the build is.

3. To check if the build configuration needs to be updated, run:

===
$ bin/bitbake-setup status
...
Configuration in /home/alex/bitbake-builds/poky-alex/ has not changed.
===

If the configuration has changed, you will see the difference as a diff.
...
  -                "rev": "akanavin/sstate-for-all"
  +                "rev": "akanavin/bitbake-setup-testing"
...

If the configuration has not changed, but layer revisions referred to it have (for example
if the configuration specifies a tip of a branch), you will see that too:

===
...
Layer repository git://git.yoctoproject.org/poky-contrib checked out into /home/alex/builds/poky-alex/layers/poky updated revision akanavin/sstate-for-all from 6b842ba55f996b27c900e3de78ceac8cb3b1c492 to aeb73e29379fe6007a8adc8d94c1ac18a93e68de
===

4. If the configuration has changed, you can bring it in sync with:

$ bin/bitbake-setup update

Note that it will also rename/preserve the existing build/conf directory, and print changes
in bitbake configuration (diff of content of build/conf/) if that has changed. I can't
at the moment think of anything more clever that is also not much more brittle or complex
to implement, but open to suggestions.

Terminology
===========

- 'top directory' means the place under which bitbake-setup reads and
writes everything. bitbake-setup makes a promise to not touch anything outside of
that, unless otherwise directed to by entries in settings (currently
there is one such setting for fetcher downloads for layers and config
registries). Top directory can be selected by an environment variable, a command line option,
or otherwise assumed to be ~/bitbake-builds/. If BBPATH is in environment
(e.g. we are in a bitbake environment), then the top directory is
deduced from that and doesn't need to be specified by hand.

- 'settings' means bitbake-setup operational parameters that are
global to all builds under a top directory. E.g. the location of
configuration registry, or where the bitbake fetcher should place the
downloads (DL_DIR setting). Settings are stored in a .conf file in ini
format just under the top directory.

- 'build' means a tree structure set up by 'bitbake-setup init',
consisting of, at least, a layers checkout, and a bitbake
build. It maps 1:1 to the json data it was constructed from, which is
called 'build configuration'. Build configurations are constructed from
generic configurations that may involve making one or more choices
about available options in them. Generic configurations are files, URLs
or are obtained from git repositories called 'config
registries', in which case they can be listed with 'bitbake-setup
list'. There can be multiple 'builds' under a top directory. Here are
two example generic configurations that showcase this:
https://github.com/kanavin/bitbake-setup-configurations/blob/main/yocto-master-options.conf.json
https://github.com/kanavin/bitbake-setup-configurations/blob/main/yocto-master-nested-configs.conf.json

- 'bitbake-setup status' will tell if a build is in sync with
the generic configuration it was made from. 'bitbake-setup update' will bring a build
in sync with a configuration if needed.

- 'bitbake build' means a particular sub-tree inside a build that
bitbake itself operates on, e.g. what is set in BBPATH/BUILDDIR
by oe-init-build-env. conf/* in that tree is 'bitbake configuration'.
Bitbake configurations are constructed from templates and fragments,
with existing mechanisms provided by oe-core. The configuration file
format is specified such that other mechanisms to set up a
bitbake build can be added; there was a mention of ability to specify
local.conf content and a set of layers directly in a configuration. I
think that scales poorly compared to templates and fragments, but I
made sure alternative ways to configure a bitbake build are possible
to add in the future :)

- 'source override' is a json file that can be used to modify revisions
and origins of layers that need to be checkout into a build (e.g.
when master branches need to be changed to master-next for purposes
of testing). Such a file is specified with a command-line option to 'init'
and an example can be seen here:
https://github.com/kanavin/bitbake-setup-configurations/blob/main/yocto-master-next.override.json
