2011-06-07siggen: don't choke with traceback when data is NoneChris Larson
Given we use bb.error, not bb.fatal, here, it seems this was intended to be non-fatal, yet we'd end up trying to concatenate None. Fix this by setting an empty task to the empty string, for the purposes of hashing. Also str() the value we get from the datastore, just in case something other than a string was stored there.

2011-05-25build/siggen: Ensure a task signature file is generated for each task that ↵Richard Purdie
is executed Tracing down signature changes and dependencies is hard unless the complete task chain can be evaultated. Since we have the data available at task exeuction time, writing it to disk makes sense. This change is suboptimal internal knowledge stamp_internal() has leaks into make_stamp() and the concepts used by this code need revisiting but the change brings enough usability benefit to warrant its inclusion despite that.

2011-01-21siggen.py: better print for task hash comparisonKevin Tian
current bitbake-diffsigs simply print out the whole 'runtaskdeps' when there's mismatch, which is not very readable. On the other hand, 'runtaskhashes' comparison is broken which assumes same key existing in two sides. This commit provides better output by figuring out differences from addition, removal or hash change. Signed-off-by: Kevin Tian <kevin.tian@intel.com>
2011-01-18bitbake: Introduce stamp-extra-info task flag into stamp filenamesDongxiao Xu
For certain tasks, we need additional information in build stamp file other than the task name and file name. stamp-extra-info is introduced as a task flag which is appended to the stamp file name.

2011-01-12bitbake/siggen.py: Fix whitelisted variable handlingRichard Purdie
Even when a variable was whitelisted, any dependencies of that variable could still creep into the task hash due to the way the whitelisting code worked. This patch changes thing to ensure that when whitelisted, that whitelisting applies to the variable and any dependencies it has. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

2011-01-06bitbake build/siggen/runqueue: Fix stampfile parametersRichard Purdie
The current parameters are not useful to the stampfile generator function as they can't uniquely define a task. This updated things so the parameters can identify unique tasks. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

2010-12-07siggen.py: fix the wrong usage on BB_TASKHASH_WHITELISTKevin Tian
BB_TASKHASH_WHITELIST is expected to filter out native tasks from the dependency list for target recipe's checksum. However current code actually implements the opposite. All native sstate packages end up to have empty task dependency while target sstate packages still have native tasks counted into the checksum. Signed-off-by: Kevin Tian <kevin.tian@intel.com>
2010-12-06siggen.py: set 'runtaskdeps' correctlyKevin Tian
Now 'runtaskdeps' is assigned before taskhash whitelist is filtered out, and thus always contains original task dependencies. This causes problem to diagnose sstate related problem. So fix it by appending filtered dep to 'runtaskdeps' in the fly. Signed-off-by: Kevin Tian <kevin.tian@intel.com>
2010-11-15siggen.py: fix comparison around runtaskdepsKevin Tian
two dep lists should be sorted before the comparison, or else it just causes false-positive confusion. Also fix 'taskdeps' to 'runtaskdeps' when printing out the difference. Signed-off-by: Kevin Tian <kevin.tian@intel.com>
