Ted Kremenek 6c7a5eae6d Revert "Revert Ted's r163489 and r163490, due to breakage."
I need to see how this breaks on other platforms when I fix the issue
that Benjamin Kramer pointed out.

This includes r163489 and r163490, plus a two line change.

Ted Kremenek 3d92699d3c Take another crack at stabilizing the emission order of analyzer
diagnostics without using FoldingSetNodeIDs.  This is done
by doing a complete recursive comparison of the PathDiagnostics.

Note that the previous method of comparing FoldingSetNodeIDs did
not end up relying on unstable things such as pointer addresses, so
I suspect this may still have some issues on various buildbots because
I'm not sure if the true source of non-determinism has been eliminated.
The tests pass for me, so the only way to know is to commit this change
and see what happens.

2012-09-07 07:40:40 +00:00
Ted Kremenek 74eb55a23d Rework the retain-release.m test to use FileCheck and the "text" output
of the analyzer, as the RetainReleaseChecker has many fine-grain
path diagnostic events that were not being checked.  This uncovered
an inconsistency between the path diagnostics between Objective-C
and Objective-C++ code in ConditionBRVisitor that was fixed in a recent
patch.

Jordan Rose eaacff4826 [analyzer] More tests for "release and stop tracking".
Under GC, a release message is ignored, so "release and stop tracking" just
becomes "stop tracking". But CFRelease is still honored. This is the main
difference between ns_consumed and cf_consumed.

2012-08-20 22:15:44 +00:00
Jordan Rose bda04301d4 [analyzer] Add a test for "release and stop tracking" behavior.
This is used to handle functions and methods that consume an argument
(annotated with the ns_consumed or cf_consumed attribute), but then the
argument's retain count may be further modified in a callback. We want
to warn about over-releasing, but we can't really track the object afterwards.

Patrick Beard acfbe9e1f2 Added a new attribute, objc_root_class, which informs the compiler when a root class is intentionally declared.
The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger
the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698>

Ted Kremenek e9a5bcf17e Change RetainCountChecker to eagerly "escape" retained objects when they are
assigned to a struct.  This is fallout from inlining results, which expose
far more patterns where people stuff CF objects into structs and pass them
around (and we can reason about it).  The problem is that we don't have
a general way to detect when values have escaped, so as an intermediate step
we need to eagerly prune out such tracking.

Ted Kremenek e9fda1e48a [analyzer] Overhaul how the static analyzer expects CFGs by forcing CFGs to be linearized only when used by the static analyzer. This required a rewrite of LiveVariables, and exposed a ton of subtle bugs.
The motivation of this large change is to drastically simplify the logic in ExprEngine going forward.

Some fallout is that the output of some BugReporterVisitors is not as accurate as before; those will
need to be fixed over time.  There is also some possible performance regression as RemoveDeadBindings
will be called frequently; this can also be improved over time.

John McCall d2930c2100 In Objective-C, pull arbitrary attributes from overridden
methods, including indirectly overridden methods like those
declared in protocols and categories.  There are mismatches
that we would like to diagnose but aren't yet, but this   
is fine for now.

I looked at approaches that avoided doing this lookup 
unless we needed it, but the infer-related-result-type
checks were doing it anyway, so I left it with the same
fast-path check for no previous declartions of that 
selector.
