bitbake: cache: Fix performance problem with large numbers of source files

2020-04-26T12:41:29+00:00

Some companies are using large numbers of patch files in SRC_URI. Rightly or wrongly that exposes a performance problem where the code does not handle the large string manipulations in a way which works efficienty in python. This is a modified version of a patch from z00539568

bitbake: lib: remove unused imports

2020-01-19T13:31:05+00:00

removed unused imports which made the code harder to read, and slightly but less efficient (Bitbake rev: 4367692a932ac135c5aa4f9f2a4e4f0150f76697) Signed-off-by: Frazer Clews Signed-off-by: Richard Purdie

bitbake: cache: Lower debug level for wold build messages

2020-01-02T16:43:01+00:00

These messages spam the logs for no good reason, they were useful for debugging a particular problem long ago but are distracting noise now. Disable them. (Bitbake rev: 1a9247c468cf09da60e5d396ccb81e950841c99e) Signed-off-by: Richard Purdie

bitbake: siggen: Clean up task reference formats

2019-08-06T10:21:32+00:00

Currently siggen uses the format "." for referencing tasks whilst runqueue uses ":". This converts to use ":" as the separator everywhere. This is an API breaking change since the cache is affected, as are siginfo files and any custom signature handlers such as those in OE-Core. Ultimately this will let us clean up and the accessor functions from runqueue, removing all the ".rsplit(".", 1)[0]" type code currently all over the place. Once a standard is used everwhere we can update the code over time to be more optimal. (Bitbake rev: 07e539e1c566ca3434901e1a00335cb76c69d496) Signed-off-by: Richard Purdie

bitbake: cache: Add SimpleCache class

2019-08-06T10:21:31+00:00

This adds a simple version of the MultiProcessCache which can be used to save and load cache data, useful for a new usecase we have in sigdata/runqueue. (Bitbake rev: 19a6e35600ae6d2d1bcecca6e68ab8c37674774e) Signed-off-by: Richard Purdie

bitbake: cache: Create a symlink for current cachefile

2019-07-19T07:45:08+00:00

So that people or other tools can easily know which one is being used, just like what we did for run.do_task and log.do_task, otherwise, we have no way to know it. I usually use "ls -t", but it isn't reliable since the one which is being used may not the latest one.

bitbake: cache: Set packages for skipped recipes

2019-07-15T08:31:48+00:00

The provides and rprovides had been set for skipped recipes, packages are similar to them (all of them provide something), so also set it. This makes it easier to figure out the RDEPENDS issues, for example, lmsensors (lmsensors_3.5.0.bb) RRECOMMENDS lmsensors-config-fancontrol (lmsensors-config_1.0.bb), but lmsensors-config is skipped for some reasons, then if we run: $ bitbake lmsensors ERROR: Nothing RPROVIDES 'lmsensors-config-fancontrol' (but /path/to/lmsensors_3.5.0.bb RDEPENDS on or otherwise requires it) NOTE: Runtime target 'lmsensors-config-fancontrol' is unbuildable, removing... Missing or unbuildable dependency chain was: ['lmsensors-config-fancontrol'] ERROR: Required build target 'lmsensors' has no buildable providers. Missing or unbuildable dependency chain was: ['lmsensors', 'lmsensors-config-fancontrol'] We had no way to know who rprovides lmsensors-config-fancontrol, we can figure it out by bitbake/contrib/dump_cache.py after this patch.

bitbake: cache: Remove duplicated lines for provides and rprovides

2019-07-15T08:31:48+00:00

Whether skip or not, they are always set, so move the lines ahead to avoid duplicated lines. (Bitbake rev: c1a8ebb8f83e5108b667f291c924fc2fbd2ac769) Signed-off-by: Robert Yang Signed-off-by: Richard Purdie

bitbake: multiconfig: Switch from 'multiconfig' -> 'mc'

2019-06-10T13:46:38+00:00

After real world use its clear the "multiconfig:" prefix to multiconfig tasks, whilst clear, is also clumbersome. Switch to use the short version instead. mcdepends will continue to work with "multiconfig:" for now as well. The commandline will only accept mc: going forward.

bitbake: bitbake: Strip old editor directives from file headers

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

There are much better ways to handle this and most editors shouldn't need this in modern times, drop the noise from the files. Its not consitently applied anyway. (Bitbake rev: 5e43070e3087d09aea2f459b033d035c5ef747d0) Signed-off-by: Richard Purdie
