-# This bbclass implements device tree compliation for user provided device tree

-# addition to device trees this bbclass also handles compilation of device tree

-# The output of this class behaves similar to how kernel-devicetree.bbclass

+# Handle Go vendor support for offline builds
+#
+# When importing Go modules, Go downloads the imported modules using
+# a network (proxy) connection ahead of the compile stage. This contradicts 
+# the yocto build concept of fetching every source ahead of build-time
+# and supporting offline builds.
+#
+# To support offline builds, we use Go 'vendoring': module dependencies are 
+# downloaded during the fetch-phase and unpacked into the modules 'vendor'
+# folder. Additionally a manifest file is generated for the 'vendor' folder
+#

-#
-# Packaging process
-#
-# Executive summary: This class iterates over the functions listed in PACKAGEFUNCS
-# Taking D and splitting it up into the packages listed in PACKAGES, placing the
-# resulting output in PKGDEST.
-#
-# There are the following default steps but PACKAGEFUNCS can be extended:
-#
-# a) package_convert_pr_autoinc - convert AUTOINC in PKGV to ${PRSERV_PV_AUTOINC}
-#
-# b) perform_packagecopy - Copy D into PKGD
-#
-# c) package_do_split_locales - Split out the locale files, updates FILES and PACKAGES
-#
-# d) split_and_strip_files - split the files into runtime and debug and strip them.
-#    Debug files include debug info split, and associated sources that end up in -dbg packages
-#
-# e) fixup_perms - Fix up permissions in the package before we split it.
-#
-# f) populate_packages - Split the files in PKGD into separate packages in PKGDEST/<pkgname>
-#    Also triggers the binary stripping code to put files in -dbg packages.
-#
-# g) package_do_filedeps - Collect perfile run-time dependency metadata
-#    The data is stores in FILER{PROVIDES,DEPENDS}_file_pkg variables with
-#    a list of affected files in FILER{PROVIDES,DEPENDS}FLIST_pkg
-#
-# h) package_do_shlibs - Look at the shared libraries generated and autotmatically add any
-#    dependencies found. Also stores the package name so anyone else using this library
-#    knows which package to depend on.
-#
-# i) package_do_pkgconfig - Keep track of which packages need and provide which .pc files
-#
-# j) read_shlibdeps - Reads the stored shlibs information into the metadata
-#
-# k) package_depchains - Adds automatic dependencies to -dbg and -dev packages
-#
-# l) emit_pkgdata - saves the packaging data into PKGDATA_DIR for use in later
-#    packaging steps

-#                    running on the same host.
-#                    Note: If more than one interface of type -device virtio-net-device gets added,
-#                          QB_NETWORK_DEVICE_prepend might be used, since Qemu enumerates the eth*
-#                          devices in reverse order to -device arguments.
-#
-# QB_TAP_OPT: network option for 'tap' mode, e.g.,
-#             "-netdev tap,id=net0,ifname=@TAP@,script=no,downscript=no"
-#              Note, runqemu will replace "@TAP@" with the one which is used, such as tap0, tap1 ...
-#
-# QB_SLIRP_OPT: network option for SLIRP mode, e.g., -netdev user,id=net0"
-#
-# QB_CMDLINE_IP_SLIRP: If QB_NETWORK_DEVICE adds more than one network interface to qemu, usually the
-#                      ip= kernel comand line argument needs to be changed accordingly. Details are documented
-#                      in the kernel docuemntation https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt
-#                      Example to configure only the first interface: "ip=eth0:dhcp"
-# QB_CMDLINE_IP_TAP: This parameter is similar to the QB_CMDLINE_IP_SLIRP parameter. Since the tap interface requires
-#                    static IP configuration @CLIENT@ and @GATEWAY@ place holders are replaced by the IP and the gateway
-#                    address of the qemu guest by runqemu.
-#                    Example: "ip=192.168.7.@CLIENT@::192.168.7.@GATEWAY@:255.255.255.0::eth0"
-#
-# QB_ROOTFS_OPT: used as rootfs, e.g.,
-#               "-drive id=disk0,file=@ROOTFS@,if=none,format=raw -device virtio-blk-device,drive=disk0"
-#              Note, runqemu will replace "@ROOTFS@" with the one which is used, such as core-image-minimal-qemuarm64.ext4.
-#
-# QB_SERIAL_OPT: serial port, e.g., "-serial mon:stdio"
-#
-# QB_TCPSERIAL_OPT: tcp serial port option, e.g.,
-#                   " -device virtio-serial-device -chardev socket,id=virtcon,port=@PORT@,host=127.0.0.1 -device virtconsole,chardev=virtcon"
-#                   Note, runqemu will replace "@PORT@" with the port number which is used.
-#
-# QB_ROOTFS_EXTRA_OPT: extra options to be appended to the rootfs device in case there is none specified by QB_ROOTFS_OPT.
-#                      Can be used to automatically determine the image from the other variables
-#                      but define things link 'bootindex' when booting from EFI or 'readonly' when using squashfs
-#                      without the need to specify a dedicated qemu configuration

-# Sets SOURCE_DATE_EPOCH in each component's build environment.
-# Upstream components (generally) respect this environment variable,
-# using it in place of the "current" date and time.
-# See https://reproducible-builds.org/specs/source-date-epoch/
-#
-# After sources are unpacked but before they are patched, we set a reproducible value for SOURCE_DATE_EPOCH.
-# This value should be reproducible for anyone who builds the same revision from the same sources.
-#
-# There are 4 ways we determine SOURCE_DATE_EPOCH:
-#
-# 1. Use the value from __source_date_epoch.txt file if this file exists.
-#    This file was most likely created in the previous build by one of the following methods 2,3,4.
-#    Alternatively, it can be provided by a recipe via SRC_URI.
-#
-# If the file does not exist:
-#
-# 2. If there is a git checkout, use the last git commit timestamp.
-#    Git does not preserve file timestamps on checkout.
-#
-# 3. Use the mtime of "known" files such as NEWS, CHANGLELOG, ...
-#    This works for well-kept repositories distributed via tarball.
-#
-# 4. Use the modification time of the youngest file in the source tree, if there is one.
-#    This will be the newest file from the distribution tarball, if any.
-#
-# 5. Fall back to a fixed timestamp.
-#
-# Once the value of SOURCE_DATE_EPOCH is determined, it is stored in the recipe's SDE_FILE.
-# If none of these mechanisms are suitable, replace the do_deploy_source_date_epoch task
-# with recipe-specific functionality to write the appropriate SOURCE_DATE_EPOCH into the SDE_FILE.
-#
-# If this file is found by other tasks, the value is exported in the SOURCE_DATE_EPOCH variable.
-# SOURCE_DATE_EPOCH is set for all tasks that might use it (do_configure, do_compile, do_package, ...)

-# testimage.bbclass enables testing of qemu images using python unittests.
-# Most of the tests are commands run on target image over ssh.
-# To use it add testimage to global inherit and call your target image with -c testimage
-# You can try it out like this:
-# - first add IMAGE_CLASSES += "testimage" in local.conf
-# - build a qemu core-image-sato
-# - then bitbake core-image-sato -c testimage. That will run a standard suite of tests.
-#
-# The tests can be run automatically each time an image is built if you set
-# TESTIMAGE_AUTO = "1"
-
-TESTIMAGE_AUTO ??= "0"
-
-# You can set (or append to) TEST_SUITES in local.conf to select the tests
-# which you want to run for your target.
-# The test names are the module names in meta/lib/oeqa/runtime/cases.
-# Each name in TEST_SUITES represents a required test for the image. (no skipping allowed)
-# Appending "auto" means that it will try to run all tests that are suitable for the image (each test decides that on it's own).
-# Note that order in TEST_SUITES is relevant: tests are run in an order such that
-# tests mentioned in @skipUnlessPassed run before the tests that depend on them,
-# but without such dependencies, tests run in the order in which they are listed
-# in TEST_SUITES.
-#
-# A layer can add its own tests in lib/oeqa/runtime, provided it extends BBPATH as normal in its layer.conf.
-
-# TEST_LOG_DIR contains a command ssh log and may contain infromation about what command is running, output and return codes and for qemu a boot log till login.
-# Booting is handled by this class, and it's not a test in itself.
-# TEST_QEMUBOOT_TIMEOUT can be used to set the maximum time in seconds the launch code will wait for the login prompt.
-# TEST_OVERALL_TIMEOUT can be used to set the maximum time in seconds the tests will be allowed to run (defaults to no limit).
-# TEST_QEMUPARAMS can be used to pass extra parameters to qemu, e.g. "-m 1024" for setting the amount of ram to 1 GB.
-# TEST_RUNQEMUPARAMS can be used to pass extra parameters to runqemu, e.g. "gl" to enable OpenGL acceleration.
-
-# TESTIMAGE_BOOT_PATTERNS can be used to override certain patterns used to communicate with the target when booting,
-# if a pattern is not specifically present on this variable a default will be used when booting the target.
-# TESTIMAGE_BOOT_PATTERNS[<flag>] overrides the pattern used for that specific flag, where flag comes from a list of accepted flags
-# e.g. normally the system boots and waits for a login prompt (login:), after that it sends the command: "root\n" to log as the root user
-# if we wanted to log in as the hypothetical "webserver" user for example we could set the following:
-# TESTIMAGE_BOOT_PATTERNS = "send_login_user search_login_succeeded"
-# TESTIMAGE_BOOT_PATTERNS[send_login_user] = "webserver\n"
-# TESTIMAGE_BOOT_PATTERNS[search_login_succeeded] = "webserver@[a-zA-Z0-9\-]+:~#"
-# The accepted flags are the following: search_reached_prompt, send_login_user, search_login_succeeded, search_cmd_finished.
-# They are prefixed with either search/send, to differentiate if the pattern is meant to be sent or searched to/from the target terminal

-# ALTERNATIVE_LINK_NAME[name] = "target"
-#
-#   This is the name of the binary once it's been installed onto the runtime.

-#   other recipes with the same functionality.
-#   i.e. ALTERNATIVE_LINK_NAME[bracket] = "/usr/bin/["

-#   This is useful when a recipe provides multiple alternatives for the

-# NOTE: If ALTERNATIVE_TARGET is not defined, it will inherit the value
