bitbake: siggen: Ensure tainted stamps are accounted for with writing custom stamps

2016-04-03T21:50:17+00:00

sstate.bbclass for example writes siginfo files to a separate location but we need to read taint data from the standard path. (Bitbake rev: da444c9761ee15a59ea8880e3f812a5d3f1a1aaa) Signed-off-by: Richard Purdie

bitbake: siggen: Fix nostamp taint handling

2016-04-03T21:50:17+00:00

The taint values need to be passed from the server to the workers to ensure they see the same stamp values. Also ensure that the "nostamp:" prefix isn't included in the checksum value to match the server calculation. This ensures the checksums are all consistent.

bitbake: siggen: Add checksum recalculation/checking code

2016-04-03T21:50:17+00:00

In theory all the information to recalcuate the task signatures was written into the siginfo/sigdata files. In reality, some of the information was written into the filename. Firstly this patch duplicates that info into the file itself just for easy of use since its small. Secondly, we abstract out the existing "calculate the checksum" code for the taskhash, and add a function to calculate the bashhash based on the informaiton within the file. Finally, we call these functions when we're writing out the data to check that the data we're writing is consistent. I've found a couple of places it wasn't and its good to know about these in advance, rather than having a siginfo/sigdata file which a given hash in its filename but a contents which give a different result. This should all combine to avoid a certain class of checksum bugs making it into world, and identifying problems in advance.

bitbake: siggen: Fix check calculation problem with file_checksums

2016-04-03T14:53:44+00:00

When I enabled debugging of the checksum code, I found the value calculated from siginfo/sigdata files for do_fetch tasks never matched. This was due to an error in the way the data was being stored for these, it wasn't ordered correctly. This patch fixes things so the checksums calculated from siginfo/sigdata files is correct when file checksums are present.

bitbake: siggen: Drop misleading duplicate method

2016-04-03T14:53:44+00:00

The real method is a few lines later, this one is incorrect and just causing confusion. Remove it. (Bitbake rev: a896f263300f069400eae533be0daf5dedf41c95) Signed-off-by: Richard Purdie

bitbake: SignatureGeneratorBasic: make checksum cache file configurable

2016-02-18T07:41:16+00:00

Define a new bitbake configuration variable BB_HASH_CHECKSUM_CACHE_FILE that can be used to define the cache file to use for file checksum cache. (Bitbake rev: a965b390d6240e279c190b92b17c0573e9bd604c) Signed-off-by: Markus Lehtonen Signed-off-by: Richard Purdie

bitbake: SignatureGenerator: add method for saving the file checksum cache

2016-02-18T07:41:15+00:00

Extend the API in order to be able to write out the file checksum cache onto disk. SignatureGeneratorBasic class now implements a method that update the fetcher local files checksum cache with the task file dependency checksums.

bitbake: siggen: Change exception note into a warning

2016-01-06T15:27:34+00:00

This makes no sense as just a note, its at least a warning and useful to get an idea of which codepath is failing. (Bitbake rev: 0194cf0da24dc72dab0612cd54aa5190e6cd92f2) Signed-off-by: Richard Purdie

bitbake: siggen: Make it clear why nostamp tasks signatures don't match

2015-10-01T06:43:38+00:00

If you run bitbake-diffsigs against two differing sigdata files from nostamp tasks it shows no difference despite the differing checksum. Change the code so this shows up as a nostamp 'taint' and at least makes the issue clearer to the end user. (Bitbake rev: 97679d18955dadaa34f9450564e44da99984d140) Signed-off-by: Richard Purdie

bitbake: siggen: Don't crash if number of task dependencies change

2015-05-26T09:33:06+00:00

If the number of task dependencies change you currently get a traceback when using diffsigs. (Bitbake rev: c6798b431571aae18bb8699ac6e3ec75b731d719) Signed-off-by: Richard Purdie
