reproducible: Merge code into base.bbclass

2021-10-16T16:41:59+00:00

Reproducibility is here to stay and needs to be part of our default workflow. Move the remaining code to base.bbclass so it is always a first class citizen and it is clear people need to be mindful of it. (From OE-Core rev: abb0671d2cebfd7e8df94796404bbe9c7f961058) Signed-off-by: Richard Purdie

reproducible: Move variable definitions to bitbake.conf

2021-10-16T16:41:59+00:00

The reproducibility code was originally developed as separate standalone class but development is no longer experimental and the code is widely tested and used by default for poky. Reproducible builds are the direction we need to take as a project. Transition the core variable definitions to bitbake.conf as part of a move to make these part of the default workflow. This also helps reduce test matrix complexity as there is now one code path. (From OE-Core rev: f38a8de19550ae216575b5b39163666f74b07e2d) Signed-off-by: Richard Purdie

reproducible: Move class function code into library

2021-10-16T16:41:59+00:00

To try and avoid parse/memory overhead of functions within bitbake, move the bulk of the reproducibility functions to the function library. (From OE-Core rev: f2fd1c9d75e774c8a5271cdc1ec6f65c4492f941) Signed-off-by: Richard Purdie

reproducible_build: Drop now unneeded compiler warning

2021-10-16T16:41:59+00:00

We now pass compiler options that mean the compiler will adjust these values to SOURCE_DATE_EPOCH, the compiler warnings are now unneeded. (From OE-Core rev: 80afddd3ae862b125f674702aff6330e87d55338) Signed-off-by: Richard Purdie

reproducible_build: Drop obsolete sstate workaround

2021-10-14T21:32:50+00:00

sstate has been sufficiently invalidated since this change was made, drop the workaround now. (From OE-Core rev: 7a497d8f30f21bafc78d0f22f3442a9cc99544cb) Signed-off-by: Richard Purdie

reproducible_build: Work around caching issues

2021-10-04T14:03:54+00:00

SOURCE_DATE_EPOCH can be expanded early in the parsing process before the class extensions are applied. This can mean the directory pointed to for the SDE can be incorrect until later in parsing. Cache the file name in the cached value and allow it to dynamically update. This isn't ideal but avoding expansion of the variable likely isn't possible and I'm not sure how else to handle this. This works around the issue until a better solution can be found. (From OE-Core rev: 44dc97cd1223e4d2b635669627ec5f796838d42d) Signed-off-by: Richard Purdie

reproducible_build/package_XXX: Ensure SDE task is in dependency chain

reproducible_build: Remove BUILD_REPRODUCIBLE_BINARIES checking

2021-09-11T21:39:19+00:00

Previously if BUILD_REPRODUCIBLE_BINARIES was set to 0, the system would fall back and select the default epoch (April 2011), but still perform the reproducible build actions. This resulted in binaries that had an unusually old date. Simplify the functions and remove the anonymous python as no longer necessary. Also improve the documentation to better explain what the class is doing and how a recipe can override the behavior if necessary.

Convert to new override syntax

2021-08-02T14:44:10+00:00

This is the result of automated script conversion: scripts/contrib/convert-overrides.py converting the metadata to use ":" as the override character instead of "_". (From OE-Core rev: 42344347be29f0997cc2f7636d9603b1fe1875ae) Signed-off-by: Richard Purdie

classes/reproducible_build: Use atomic rename for SDE file

2021-06-03T22:09:42+00:00

If an existing source date epoch file was found during do_unpack, it was deleted and a new one would be written in its place. This causes a race with check-before-use code in get_source_date_epoch_value. Resolve the problem by making do_unpack write the new source date epoch to a temporary file, then do an atomic rename to ensure it's always present, and change the check-before-use code to use a EAFP exception instead of checking for file existence.
