-OpenEmbedded-Core and Yocto Project Maintainer Information
-==========================================================
-
-OpenEmbedded and Yocto Project work jointly together to maintain the metadata,
-layers, tools and sub-projects that make up their ecosystems.
-
-The projects operate through collaborative development. This currently takes
-place on mailing lists for many components as the "pull request on github"
-workflow works well for single or small numbers of maintainers but we have
-a large number, all with different specialisms and benefit from the mailing
-list review process. Changes therefore undergo peer review through mailing
-lists in many cases.
-
-This file aims to acknowledge people with specific skills/knowledge/interest
-both to recognise their contributions but also empower them to help lead and
-curate those components. Where we have people with specialist knowledge in
-particular areas, during review patches/feedback from these people in these
-areas would generally carry weight.
-
-This file is maintained in OE-Core but may refer to components that are separate
-to it if that makes sense in the context of maintainership. The README of specific
-layers and components should ultimately be definitive about the patch process and
-maintainership for the component.

-Testing
--------
-
-Bitbake has a testsuite located in lib/bb/tests/ whichs aim to try and prevent regressions.
-You can run this with "bitbake-selftest". In particular the fetcher is well covered since
-it has so many corner cases. The datastore has many tests too. Testing with the testsuite is
-recommended before submitting patches, particularly to the fetcher and datastore. We also
-appreciate new test cases and may require them for more obscure issues.
-
-To run the tests "zstd" and "git" must be installed.
-
-The assumption is made that this testsuite is run from an initialized OpenEmbedded build
-environment (i.e. `source oe-init-build-env` is used). If this is not the case, run the
-testsuite as follows:
-
-    export PATH=$(pwd)/bin:$PATH
-    bin/bitbake-selftest
-
-The testsuite can alternatively be executed using pytest, e.g. obtained from PyPI (in this
-case, the PATH is configured automatically):

-Note that the default Anonymous permissions are designed to not break existing

-you want to use authentication, it is recommended that you use "--anon-perms
-@read" to only give anonymous users read access, or "--anon-perms @none" to
-give un-authenticated users no access at all.
-
-Setting "--anon-perms @all" or "--anon-perms @user-admin" is not allowed, since
-this would allow anonymous users to manage all users accounts, which is a bad
-idea.
-
-If you are using user authentication, you should run your server in websockets
-mode with an SSL terminating load balancer in front of it (as this server does
-not implement SSL). Otherwise all usernames and passwords will be transmitted
-in the clear. When configured this way, clients can connect using a secure
-websocket, as in "wss://SERVER:PORT"

-The following permissions are supported by the server:
-
-    @none       - No permissions
-    @read       - The ability to read equivalent hashes from the server
-    @report     - The ability to report equivalent hashes to the server
-    @db-admin   - Manage the hash database(s). This includes cleaning the
-                  database, removing hashes, etc.
-    @user-admin - The ability to manage user accounts. This includes, creating

-It uses the `Google Cloud Storage Python Client <https://cloud.google.com/python/docs/reference/storage/latest>`__
-to check the status of objects in the bucket and download them.
-The use of the Python client makes it substantially faster than using command
-line tools such as gsutil.
-
-The fetcher requires the Google Cloud Storage Python Client to be installed, along
-with the gsutil tool.
-
-The fetcher requires that the machine has valid credentials for accessing the
-chosen bucket. Instructions for authentication can be found in the
-`Google Cloud documentation <https://cloud.google.com/docs/authentication/provide-credentials-adc#local-dev>`__.
-
-If it used from the OpenEmbedded build system, the fetcher can be used for
-fetching sstate artifacts from a GCS bucket by specifying the
-``SSTATE_MIRRORS`` variable as shown below::
-
-   SSTATE_MIRRORS ?= "\
-       file://.* gs://<bucket name>/PATH \
-   "
-
-The fetcher can also be used in recipes::
-
-   SRC_URI = "gs://<bucket name>/<foo_container>/<bar_file>"
-
-However, the checksum of the file should be also be provided::

-
--  *"version":* The NPM package version. This is a mandatory parameter.
-
--  *"downloadfilename":* Specifies the filename used when storing the downloaded file.
-
--  *"destsuffix":* Specifies the directory to use to unpack the package (default: ``npm``).
-
-Note that NPM fetcher only fetches the package source itself. The dependencies

-================
-Variable Context
-================
-
-|
-
-Variables might only have an impact or can be used in certain contexts. Some
-should only be used in global files like ``.conf``, while others are intended only
-for local files like ``.bb``. This chapter aims to describe some important variable
-contexts.
-
-.. _ref-varcontext-configuration:
-
-BitBake's own configuration
-===========================
-
-Variables starting with ``BB_`` usually configure the behaviour of BitBake itself.
-For example, one could configure:
-
-- System resources, like disk space to be used (:term:`BB_DISKMON_DIRS`),
-  or the number of tasks to be run in parallel by BitBake (:term:`BB_NUMBER_THREADS`).
-
-- How the fetchers shall behave, e.g., :term:`BB_FETCH_PREMIRRORONLY` is used
-  by BitBake to determine if BitBake's fetcher shall search only
-  :term:`PREMIRRORS` for files.
-
-Those variables are usually configured globally.
-
-BitBake configuration
-=====================
-
-There are variables:
-
-- Like :term:`B` or :term:`T`, that are used to specify directories used by
-  BitBake during the build of a particular recipe. Those variables are
-  specified in ``bitbake.conf``. Some, like :term:`B`, are quite often
-  overwritten in recipes.
-
-- Starting with ``FAKEROOT``, to configure how the ``fakeroot`` command is
-  handled. Those are usually set by ``bitbake.conf`` and might get adapted in a
-  ``bbclass``.
-
-- Detailing where BitBake will store and fetch information from, for
-  data reuse between build runs like :term:`CACHE`, :term:`DL_DIR` or
-  :term:`PERSISTENT_DIR`. Those are usually global.
-
-
-Layers and files
-================
-
-Variables starting with ``LAYER`` configure how BitBake handles layers.
-Additionally, variables starting with ``BB`` configure how layers and files are
-handled. For example:
-
-- :term:`LAYERDEPENDS` is used to configure on which layers a given layer
-  depends.
-
-- The configured layers are contained in :term:`BBLAYERS` and files in
-  :term:`BBFILES`.
-
-Those variables are often used in the files ``layer.conf`` and ``bblayers.conf``.
-
-Recipes and packages
-====================
-
-Variables handling recipes and packages can be split into:
-
-- :term:`PN`, :term:`PV` or :term:`PF` for example, contain information about
-  the name or revision of a recipe or package. Usually, the default set in
-  ``bitbake.conf`` is used, but those are from time to time overwritten in
-  recipes.
-
-- :term:`SUMMARY`, :term:`DESCRIPTION`, :term:`LICENSE` or :term:`HOMEPAGE`
-  contain the expected information and should be set specifically for every
-  recipe.
-
-- In recipes, variables are also used to control build and runtime
-  dependencies between recipes/packages with other recipes/packages. The
-  most common should be: :term:`PROVIDES`, :term:`RPROVIDES`, :term:`DEPENDS`,
-  and :term:`RDEPENDS`.
-
-- There are further variables starting with ``SRC`` that specify the sources in
-  a recipe like :term:`SRC_URI` or :term:`SRCDATE`. Those are also usually set
-  in recipes.
-
-- Which version or provider of a recipe should be given preference when
-  multiple recipes would provide the same item, is controlled by variables
-  starting with ``PREFERRED_``. Those are normally set in the configuration
-  files of a ``MACHINE`` or ``DISTRO``.

-There are expectations of users of the fetcher code. This file attempts to document
-some of the constraints that are present. Some are obvious, some are less so. It is
-documented in the context of how OE uses it but the API calls are generic.
-
-a) network access for sources is only expected to happen in the do_fetch task.
-   This is not enforced or tested but is required so that we can:
-
-   i) audit the sources used (i.e. for license/manifest reasons) 
-   ii) support offline builds with a suitable cache
-   iii) allow work to continue even with downtime upstream
-   iv) allow for changes upstream in incompatible ways
-   v) allow rebuilding of the software in X years time
-
-b) network access is not expected in do_unpack task.
-
-c) you can take DL_DIR and use it as a mirror for offline builds.
-
-d) access to the network is only made when explicitly configured in recipes
-   (e.g. use of AUTOREV, or use of git tags which change revision).
-
-e) fetcher output is deterministic (i.e. if you fetch configuration XXX now it 
-   will match in future exactly in a clean build with a new DL_DIR).
-   One specific pain point example are git tags. They can be replaced and change
-   so the git fetcher has to resolve them with the network. We use git revisions
-   where possible to avoid this and ensure determinism.
-
-f) network access is expected to work with the standard linux proxy variables
-   so that access behind firewalls works (the fetcher sets these in the 
-   environment but only in the do_fetch tasks).
-
-g) access during parsing has to be minimal, a "git ls-remote" for an AUTOREV 
-   git recipe might be ok but you can't expect to checkout a git tree.
-
-h) we need to provide revision information during parsing such that a version
-   for the recipe can be constructed.
-
-i) versions are expected to be able to increase in a way which sorts allowing 
-   package feeds to operate (see PR server required for git revisions to sort).
-
-j) API to query for possible version upgrades of a url is highly desireable to 
-   allow our automated upgrage code to function (it is implied this does always 
-   have network access).
-
-k) Where fixes or changes to behaviour in the fetcher are made, we ask that 
-   test cases are added (run with "bitbake-selftest bb.tests.fetch"). We do 
-   have fairly extensive test coverage of the fetcher as it is the only way
-   to track all of its corner cases, it still doesn't give entire coverage 
-   though sadly.
-   
-l) If using tools during parse time, they will have to be in ASSUME_PROVIDED
-   in OE's context as we can't build git-native, then parse a recipe and use
-   git ls-remote.
-
-Not all fetchers support all features, autorev is optional and doesn't make
-sense for some. Upgrade detection means different things in different contexts
-too.

-    in the download step, as the unpack step does not have network access.
-    The default is "1", set lfs=0 to skip.
