bitbake: parse: Improve/fix cache invalidation via mtime

2024-05-29T14:50:00+00:00

We have been seeing obscure failures in devtool, particularly on newer autobuilder workers where it appears the cache is assumed to be valid when it shouldn't be. We're using the 'seconds' granulation mtime field which is not really a good way of telling if a file has changed. We can switch to the "ns" version which is better however also add in inode number and size as precautions. We already have all this data and tuples are fast so there isn't really any cost to do so. This hopefully fixes [YOCTO #15318].

bitbake: lib: Drop inotify support and replace with mtime checks

2023-09-18T10:35:05+00:00

With the flush in serverlog() removed and a memory resident bitbake with a 60s timeout, the following could fail in strange ways: rm bitbake-cookerdaemon.log bitbake-layers add-layer ../meta-virtualization/ bitbake-layers add-layer ../meta-openembedded/meta-oe/ bitbake -m specifically that it might error adding meta-oe with an error related to meta-virt. This clearly shows that whilst bblayers.conf was modified, bitbake was not recognising that. This would fit with the random autobuilder issues seen when the serverlog flush() call was removed. The issue appears to be that you have no way to "sync()" the inotify events with the command stream coming over the socket. There is no way to know if there are changes in the IO queue which bitbake needs to wait for before proceeding with the next command. I did experiment with os.sync() and fsync on the inotify fd, however nothing addressed the issue. Since it is extremely important we have accurate cache data, the only realistic thing to do is to switch to stat() calls and check mtime. For bitbake commands, this is straightforward since we can revalidate the cache upon new connections/commands. For tinfoil this is problematic and we need to introduce and explict command "revalidateCaches" that the code can use to force bitbake to re-check it's cache validity. I've exposed this through tinfoil with a new "modified_files" function. So, this patch: a) drops inotify support within bitbake's cooker/server and switch to using mtime b) requires a new function call in tinfoil when metadata has been modified (Bitbake rev: da3ec3801bdb80180b3f1ac24edb27a698415ff7) Signed-off-by: Richard Purdie

bitbake: parse: Add support for addpylib conf file directive and BB_GLOBAL_PYMODULES

2022-12-08T11:15:47+00:00

For many years OE-Core has injected it's own python modules into the python namespace using an immediate expansion of a variable in base.bbclass. It also added all entries from BBPATH to sys.path. We really need this to become a first class citizen of the langauge, this new addpylib directive allows that. Usage is of the form: addpylib The namespace is imported and if there is an attribute BBIMPORT, that list of names is iterated and imported too. This mirrors what OE-Core has done for a long time with one difference in implmentation, sys.path is only appended to. This means later imported namespaces can't overwrite an earlier one and can't overwrite the main python module space. In practice we've never done that and it isn't something we should encourage or support. The new directive is only applied for .conf files and not other filetypes as it only makes sense in that context. It is also only allowed in the "base configuration" context of cookerdata since adding it at the recipe level wouldn't work properly due to the way it changes the global namespace. At the same time, move the list of modules to place in the global namespace into a BB_GLOBAL_PYMODULES variable. It is intended that only the core layer should touch this and it is meant to be a very small list, usually os and sys. BB_GLOBAL_PYMODULES is expected to be set before the first addpylib directive. Layers adding a lib directory will now need to use this directive as BBPATH is not going to be added automatically by OE-Core in future. The directives are immediate operations so it does make modules available sooner than the current OE-Core approach. The new code appends to sys.path rather than prepends as core did, as overwriting python standard library modules would be a bad idea and naturally encouraging people to collaborate around our own core modules is desireable.

bitbake: parse: Ensure any existing siggen is closed down first

We're still seeing issues with unclosed asyncio event loops. At the init site, make sure any existing one is closed first to try and avoid this. (Bitbake rev: 78dee3c03c75a27531fcff26f9298fce2519bdde) Signed-off-by: Richard Purdie

bitbake: logging: Make bitbake logger compatible with python logger

2021-02-10T23:48:16+00:00

The bitbake logger overrode the definition of the debug() logging call to include a debug level, but this causes problems with code that may be using standard python logging, since the extra argument is interpreted differently. Instead, change the bitbake loggers debug() call to match the python logger call and add a debug2() and debug3() API to replace calls that were logging to a different debug level.

bitbake: bitbake: Drop duplicate license boilerplace text

2019-05-04T09:44:10+00:00

With the introduction of SPDX-License-Identifier headers, we don't need a ton of header boilerplate in every file. Simplify the files and rely on the top level for the full licence text. (Bitbake rev: 695d84397b68cc003186e22f395caa378b06bc75) Signed-off-by: Richard Purdie

bitbake: bitbake: Add initial pass of SPDX license headers to source code

2019-05-04T09:44:04+00:00

This adds the SPDX-License-Identifier license headers to the majority of our source files to make it clearer exactly which license files are under. The bulk of the files are under GPL v2.0 with one found to be under V2.0 or later, some under MIT and some have dual license. There are some files which are potentially harder to classify where we've imported upstream code and those can be handled specifically in later commits. The COPYING file is replaced with LICENSE.X files which contain the full license texts. (Bitbake rev: ff237c33337f4da2ca06c3a2c49699bc26608a6b) Signed-off-by: Richard Purdie
