bitbake: codeparser: Allow code visitor expressions to be declared in metadata

2024-08-29T20:58:19+00:00

Allow the metadata to define code visitor expressions which mean that custom dependencies can be handled in function libraries. An example is the qa.handle_error function in OE which can set something like: """ def handle_error_visitorcode(name, args): execs = set() contains = {} warn = None if isinstance(args[0], ast.Constant) and isinstance(args[0].value, str): for i in ["ERROR_QA", "WARN_QA"]: if i not in contains: contains[i] = set() contains[i].add(args[0].value) else: warn = args[0] execs.add(name) return contains, execs, warn handle_error.visitorcode = handle_error_visitorcode """ Meaning that it can have contains optimisations on ERROR and WARN_QA instead of hard dependencies. One drawback to this solution is the parsing order. Functions with visitorcode need to be defined before anything else references them or the visitor code will not function for the earlier references.

bitbake: codeparser: Skip non-local functions for module dependencies

2024-07-01T12:53:23+00:00

If modules do something like "from glob import glob" then we end up checksumming the glob code. That leads to bugs as the code can change between different python versions for example, leading to checksum instability. We should ignore functions not from the current file as implemented by this change. (Bitbake rev: 1e6f862864539d6f6a0bea3e4479e0dd40ff3091) Signed-off-by: Richard Purdie

bitbake: codeparser/data: Ensure module function contents changing is accounted for

2024-07-01T12:53:23+00:00

Currently, if a pylib function changes contents, the taskhash remains unchanged since we assume the functions have stable output. This is probably a poor assumption so take the code of the function into account in the taskhashes. This avoids certain frustrating build failures we've been seeing in automated testing. To make this work we have to add an extra entry to the python code parsing cache so that we can store the hashed function contents for efficiency as in the python module case, that isn't used as the key to the cache. The cache version changes since we're adding data to the cache. (Bitbake rev: b2c3438ebe62793ebabe2c282534893908d520b4) Signed-off-by: Richard Purdie

bitbake: codeparser: support shell substitutions in quotes

2024-05-21T13:14:41+00:00

The current shell substitution mechanism only works without quotes. For example: var1=$(cmd1 ...) Will work and add `cmd1` to the correspondind `run.do_*` file. However, although quite common, this syntax is not supported: var1="$(cmd1 ...)" This commit adds this feature by adding a step to process_words() to check whether we are dealing with quotes first, and by iterating on what's between them to detect new shell substitution candidates. These candidates are tested and parsed like before in the next step. The original `part` being part of the candidates means the syntax var1=$(cmd1 ...) is still valid.

bitbake: cache/codeparser: Switch to a new BB_CACHEDIR variable for cache location

2023-01-26T21:50:31+00:00

Currently the codeparser cache is set from CACHE, which is typically in bitbake.conf which means we can't read/write any cache until it is found/read. We may well have python expressions to parse before that happens. The net result is suboptimal functioning of the codeparser cache since it will often be invalidated by data that is never written. This patch changes the codeparser and filechecksum caches to use BB_CACHE as their setting and defaults it to ${TOPDIR}/cache. The patch doesn't change where the "persistent" data such as prserver and hash-equiavalance resides (PERSISTENT_DIR) or where the metadata parsing cache resists (still currently CACHE). I've left those for a later patch. The patch does ensure data parsed by the core datastore parsing calls is written back since this is now much more useful after this change.
