bitbake: codeparser: Fix var_execs to append to execs, not references

2014-03-02T17:25:29+00:00

When using the "execs" information in new code, it became clear that the returned data was incorrect and there were missing exec'd functions. This corrects the error and changes one of the test results to match the correct behaviour. (Bitbake rev: 8a24f2d3b735bbc59ca4a09670cabbadb1868c1a) Signed-off-by: Richard Purdie

bitbake: codeparser/data_smart: Optimise parsing speed

2013-12-03T17:45:53+00:00

The previous "contains" changes caused a ~3% parsing speed impact. Looking at the cause of those changes was interesting: * Use of defaultdict was slower than just checking for missing entries and setting them when needed. * Even the "import collections" adversely affects parsing speed * There was a missing intern function for the contains cache data * Setting up a log object for each variable has noticeable overhead due to the changes in the code paths uses, we can avoid this. * We can call getVarFlag on "_content" directly within VariableParse for a noticeable speed gain since its a seriously hot code path. This patch therefore tweaks the code based on the above observations to get some of the speed back. (Bitbake rev: fca802187a2a30686a8a07d2b6b16a3e5716e293) Signed-off-by: Richard Purdie

bitbake: data/codeparser: Improve handling of contains functions

2013-11-26T23:01:33+00:00

One of the current frustrations with the sstate checksums is that code like base_contains('X', 'y',...) adds a full dependency on X and varies depend even on whitespace changes in X. This patch adds special handling of the contains functions to expand the first parameter and check for the flag specified by the second parameter (assuming its a string). The result is then appended to the value of the variable with a "Set" or "Unset" status. If the flag is added/removed, the stored variable value changes and hence the checksum changes. No dependency on X is added so it is free to change with regard to other flags or whitespace. This code is far from ideal, ideally we'd have properly typed variables however it fixes a major annoyance of the current checksums and is of enough value its worth adding in a stopgap solution. It shouldn't significantly restrict any propely typed variable implementation in future.

bitbake: codeparser: Drop unneeded variable separation

2013-11-26T23:01:32+00:00

There is no good reason to separately track var_references and references so merge them and remove the unneeded variable. (Bitbake rev: 64d4cbd6360c96574cece70205ea3aecc3f8bae6) Signed-off-by: Richard Purdie

bitbake: codeparser: Track bb.utils.contains usage

2013-02-15T12:12:35+00:00

The bb.utils.contains function usage is getting increasingly used in the metadata but isn't handled automatically by the python dependency tracking code. This patch changes that and also adds the "OE" names for the functions. Whilst there are reasons this is a bad idea, its likely outweighed by the shear number of these references and the current holes in dependency information which we're now relying heavily upon.

bitbake: codeparser: Track appendVar and prependVar calls as we do for getVar

2013-02-15T12:12:35+00:00

We need to track appendVar and prependVar calls just as we do for getVar in order to ensure we're not missing variable dependencies. (Bitbake rev: 767b4751232f4ee3979deb4d3f733fcf9ee2bd44) Signed-off-by: Richard Purdie

bitbake: refactor out codeparser cache into a separate class

2012-05-23T10:33:18+00:00

We want to be able to reuse most this functionality for the file checksum cache. (Bitbake rev: 0fe3cb1438d297f90dd0fc6b26362ecbff75c76d) Signed-off-by: Paul Eggleton Signed-off-by: Richard Purdie

codeparser: Compute extra cache components on the fly rather than later

2012-03-12T15:52:33+00:00

In the initial implementation there was a relcutance on my part to generate incremental cache components on the fly since it would lead to some duplicate code. We are now seeing problems where each thread reading in the saved cache file causes significant overhead and can make the process appear to hang on a many core build, particularly when the cache file is large. This patch changes the code to maintain the delta in a separate dict right from the start. The code duplication isn't too bad and could be mitigated in other ways if it becomes an issue.
