* build,json: fix compatibility with Python 3.5Paul Spooren2020-07-131-1/+1
| | | | | | | | The f-string feature was introduced in Python 3.6. As Buildbots may run on Debian 9, which comes per default with Python 3.5, this would cause an issue. Instead of f-strings use the *legacy* `.format()` function. Signed-off-by: Paul Spooren <mail@aparcar.org>
* build: fix compatibility with python 3.6Huangbin Zhan2020-07-071-3/+4
| | | | | | | | On a system python3 is linked to python3.6, fail to perform json_overview_image_info and got `TypeError: __init__() got an unexpected keyword argument 'capture_output'`. This patch emulate the behaviour on python 3.7+. Signed-off-by: Huangbin Zhan <zhanhb88@gmail.com>

* build,json: store arch_packages in profiles.jsonPaul Spooren2020-07-031-2/+5
| | | | | | | | | The `arch_packages` contains the supported package architecture. Previously it was necessary to parse the `Packages` index for the line `Architecture:`, requiring both an additional parser and file download. Signed-off-by: Paul Spooren <mail@aparcar.org>
* build: store default/device packages in JSONPaul Spooren2020-06-301-2/+18
| | | | | | | | | | | | With this commit the `profiles.json` contain both the target specific `default_packages` as well as the device specific `device_packages` as a array of strings. This information is required for downstream projects like the various web-based interactive firmware generators.

* scripts: JSON merge don't crash if no JSON foundPaul Spooren2020-04-141-2/+0
| | | | | | | | | | | | | | | | | | The JSON `WORK_DIR` ($(KDIR)/json_info_files) is only created if the new image generation methods from `image.mk` are used. However some targets like `armvirt` do not use it yet, so the folder is never created. The `json_overview_image_info.py` script used to raise an error if the given `WORK_DIR` isn't a folder, however it should just notify about missing JSON files. This patch removes the Python assert and exists with code 0 even if no JSON files were found, as this is not necessarily an error but simply not yet implemented. Using `glob` on an not existing `Path` results in an empty list, therefore the for loop won't run. Signed-off-by: Paul Spooren <mail@aparcar.org> CC: Petr Štetiar <ynezz@true.cz>
* build: refactor JSON info files to `profiles.json`Paul Spooren2020-04-031-0/+39
JSON info files contain machine readable information of built profiles and resulting images. These files were added in commit 881ed09ee6e2 ("build: create JSON files containing image info"). They are useful for firmware wizards and script checking for reproducibility. Currently all JSON files are stored next to the built images, resulting in up to 168 individual files for the ath79/generic target. This patch refactors the JSON creation to store individual per image (not per profile) files in $(BUILD_DIR)/json_info_files and create an single overview file called `profiles.json` in the target directory. Storing per image files and not per profile solves the problem of parallel file writes. If a profiles sysupgrade and factory image are finished at the same time both processes would write to the same JSON file, resulting in randomly broken outputs. Some target like x86/64 do not use the image code yet, resulting in missing JSON files. If no JSON info files were created, no `profiles.json` files is created as it would be empty anyway. As before, this creation is enabled by default only if `BUILDBOT` is set. Tested via buildroot & ImageBuilder on ath79/generic, imx6 and x86/64.
