bitbake: bitbake: data_smart.py and friends: Track variable history

2013-01-18T12:35:19+00:00

This patch adds tracking of the history of variable assignments. The changes are predominantly localized to data_smart.py and parse/ast.py. cooker.py and data.py are altered to display the recorded data, and turn tracking on for the bitbake -e case. The data.py update_data() function warns DataSmart.finalize() to report the caller one further back up the tree. In general, d.setVar() does what it used to do. Optionally, arguments describing an operation may be appended; if none are present, the operation is implicitly ignored. If it's not ignored, it will attempt to infer missing information (name of variable, value assigned, file and line) by examining the traceback. This slightly elaborate process eliminates a category of problems in which the 'var' member of the keyword arguments dict is set, and a positional argument corresponding to 'var' is also set. It also makes calling much simpler for the common cases. The resulting output gives you a pretty good picture of what values got set, and how they got set. RP Modifications: a) Split from IncludeHistory to separate VariableHistory b) Add dedicated copy function instead of deepcopy c) Use COW for variables dict d) Remove 'value' loginfo value and just use 'details' e) Desensitise code for calling order (set 'op' before/after infer_caller_details was error prone) f) Fix bug where ?= "" wasn't shown correctly g) Log more set operations as some variables mysteriously acquired values previously h) Standardise infer_caller_details to be triggered from .record() where at all possible to reduce overhead in non-enabled cases i) Rename variable parameter names to match inference code j) Add VariableHistory emit() function to match IncludeHistory k) Fix handling of appendVar, prependVar and matching flag ops l) Use ignored=True to stop logging further events where appropriate (Bitbake rev: f00524a3729000cbcb3317fee933ac448fae5e2d) Signed-off-by: Peter Seebach Signed-off-by: Richard Purdie

bitbake: BBHandler/ast: Simplify/fix EXPORT_FUNCTIONS usage

2012-12-11T15:59:42+00:00

The current usage of EXPORT_FUNCTIONS is rather problematic since a class list (classes) is passed into the ast statement and cached as it was when first parsed. This class list may be different in other cases but is locked once in the cache. Worse, the construction of classes can be broken by exceptions during parsing at the wrong moments since the state of the parser is not always reset correctly. This can lead to leakage of other classes into the classes list. The current EXPORT_FUNCTIONS implementation looks at the last two currently inherited classes and sets up an indirect function call view the second last class inherited, e.g.: do_configure calls gnomebase_do_configure gnomebase_do_configure calls autotools_do_configure This intermediary doesn't seem to serve a useful purpose. This patch therefore makes builds deterministic and fixes various cache problems and indirection by removing the intermediaries and simply performing directly mapping for the cases where its needed.

bitbake: ast: Store anonymous python function contents in the datstore

2012-08-23T08:22:44+00:00

This is useful if we need to disable part of one during a backtrace for debugging purposes. (Bitbake rev: 80a0c1b06a30a6ba9977c29fac0437a208d8cbbc) Signed-off-by: Richard Purdie

bitbake: ast: Extract text variable in PythonMethodNode

bitbake: ast: Rename PythonMethodNode define variable to modulename

2012-08-23T08:22:44+00:00

It was hard for me to understand what the define variable was, modulename is hopefully a bit better. (Bitbake rev: 79f9f46319de85f85613ebe248c327f5852225ba) Signed-off-by: Richard Purdie

bitbake: methodpool: Clean up the parsed module list handling to be slightly less insane

2012-08-23T08:22:44+00:00

This removes some dubious functions and replaces them with a simpler, cleaner API which better describes what the code is doing. Unused code/variables are removed and comments tweaked. (Bitbake rev: f1e943aebfb84e98253f3f21646d6765c4fa1d66) Signed-off-by: Richard Purdie

bitbake: event/ast: Use better_exec instead of simple_exec

2012-08-22T12:59:57+00:00

This improves the stacktraces dumped by bitbake when for example anonymous python functions fail. Also default to passing code strings to better_exec to match the behaviour of simple_exec to aid the transition. (Bitbake rev: 7e8205929ae953731a6854ea80b197847cff5771) Signed-off-by: Richard Purdie

bitbake: bitbake: Warn upon finding tab indentation in python functions

2012-07-19T09:24:50+00:00

Mixed spacing in python functions can cause subtle issues and generally confuses users. We've standardised on 4 space indentation, adding this warning helps ensure consistency and avoid bugs. It also makes _prepend and _append operations on python functions slightly less risky. (Bitbake rev: c51cfaf48d3b12a19b01e824b6ba4230376bcad4) Signed-off-by: Richard Purdie

parse/ast: Expand inherit statements before splitting them

2012-03-15T22:56:16+00:00

This means that statements that expand to more then one entry such as: CLASSES = "a b" inherit ${CLASSES} work correctly instead of trying to inherit a class called "a b". (Bitbake rev: 2568e9ace6e6f483e1bf2a9ef2f4d8318d6c85b7) Signed-off-by: Richard Purdie

bitbake: Added BBINCLUDED variable.

2012-02-28T12:27:21+00:00

Added new variable BBINCLUDED indicating the file dependency information. It exposes the internal variable '__base_depends' and '__depends'. (Bitbake rev: af524a656fce32d01687481b86c31bef00eb9fc3) Signed-off-by: Lianhao Lu Signed-off-by: Richard Purdie
