2011-11-24data/siggen: Add vardepvalue mechanism to allow the variable dependency code ↵Richard Purdie
to be forced to specific values We have a problem if we want to inject specific information into the variable dependency code. There are cases for example where we want a dependency on the value of X but it doesn't matter how X was constructed or what dependencies it might have had, we only care about the absolute value. With the current code, its near enough impossible to do this. This patch adds such a mechanism so the user can trigger this with code like: baselib[vardepvalue] = "${baselib}" It also refactors some of the code so we do variable lookups once instead of doing this in two different functions.

2011-11-23siggen.py: sort task hash depedencies with basepathMatthew McClintock
Without this patch the tash hash dependencies can be in a order that is dependent upon directory/filesystem layout. With this change the data is sorted the same regardless. Without this the dependent hashes could be in different orders on different systems and consequently final md5 hash would differ as well even though nothing else changed.

2011-11-18siggen.py: Include list of variables in hashesRichard Purdie
Ensure that the list of dependencies is included in the hash as well as their contents Prior to this, adding or removing dependencies with values of "None" would not change the hash, despite diffsigs reporting this difference.

2011-11-18siggen.py: Fix diffsigs output for filename comparisionsRichard Purdie
When comparing sig files, if the recipe locations had changed, the dependent tasks list would show as changed even if the actual hash had not changed. This updates the code to only compare the base part of the pathnames. It also tweaks some of the output to add newlines to aid comparing two lists of variables as it makes the location of the difference clearer.

2011-09-05lib/bb/siggen.py: return a string from noop get_taskhashDmitry Eremin-Solenikov
OpenEmbedded is expecting to get a string from get_taskhash, but noop siggen returns just 0 (number), so OE classes/sstate.bbclass barfs badly. Fix that.

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

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
