Commit22b6945552(support/scripts/cve.py: switch from NVD to FKIE for the JSON files) had to change the decompressor from gz to xz, as the new location is using xz compression. That commit mentioned that it was spawning an external xz process to do the decompression, on the pretence that "there is no xz decompressor in Python stdlib." Before version 3.1, ijson.items() only accepted a file-like object as input (that file-like object could yield bytes() or str(), both were supported). Starting with version 3.1, ijson.items() also accepts that it be directly passed bytes() or str() directly. subprocess.check_output() means we are now passing bytes() to ijson.items(), so it fails on ijson versions before 3.1, with failures such as: [...] File "/usr/lib/python3/dist-packages/ijson/backends/python.py", line 25, in Lexer if type(f.read(0)) == bytetype: AttributeError: 'bytes' object has no attribute 'read' Ubuntu 20.04, on which the pkg-stats run to generate the daily report, only has ijson 2.3. More recent distros have more recent versions of ijson, like Fedora 39 that has 3.2.3, recent enough to support being fed bytes(). Commit22b6945552was tested on Fedora 39, so did not catch the issue. However, the reasoning in22b6945552is wrong: there *is* the lzma module, at least since python 3.3 (that is, aeons ago), which is able to read xz-compressed files; it also has an API similar to the gzip module, and can provide a file-like object that exposes the decompressed data. So, do just that: provide an lzma-wrapped file-like object to ijson, so that we can eventually recover our daily reports that everything is broken! :-] Note that this construct still works on recent versions!

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
