Add a function to make it easier to debug a test failure caused by an
unexpected state.
Currently, tests are using assertEqual which results in a cryptic error
message: "AssertionError: 5 != 10". Even when a test provides a message
to make it clear why a particular state is expected, you still have to
figure out which of the two was the expected state, and what the other
value corresponds to.
We have a function in lldbutil that helps you convert the state number
into a user readable string. This patch adds a wrapper around
assertEqual specifically for comparing states and reporting better error
messages.
The aforementioned error message now looks like this: "AssertionError:
stopped (5) != exited (10)". If the user provided a message, that
continues to get printed as well.

After changing the "fallback" behavior when a user sets a breakpoint
without specifying a module the bad-address-breakpoint test case failed
incorrectly. This patch updates that test case in order to more
thoroughly discover an illegal address and use that as the means for
testing whether a breakpoint set at an illegal address fails to resolve.

symbol name matches. Instead, we extract the incoming path's base
name, look up all the symbols with that base name, and then compare
the rest of the context that the user provided to make sure it
matches. However, we do this comparison using just a strstr. So for
instance:
break set -n foo::bar
will match not only "a::foo::bar" but "notherfoo::bar". The former is
pretty clearly the user's intent, but I don't think the latter is, and
results in breakpoints picking up too many matches.
This change adds a Language::DemangledNameContainsPath API which can
do a language aware match against the path provided. If the language
doesn't provide this we fall back to the strstr (though that's changed
to StringRef::contains in the patch).

Replace forms of `assertTrue(err.Success())` with `assertSuccess(err)` (added in D82759).
* `assertSuccess` prints out the error's message
* `assertSuccess` expresses explicit higher level semantics, both to the reader and for test failure output
* `assertSuccess` seems not to be well known, using it where possible will help spread knowledge
* `assertSuccess` statements are more succinct

Adding the to be loaded dylib to the extra images causes the breakpoint
to be found in the image added to the target on Linux (though not on
Darwin). So adjust the test for this difference.
I added some tests for the case where the breakpoints take immediately
to the extant test case, and made a new test case for when the source
regex breakpoint will be set in a dlopen-ed library.
I also noticed when doing this that "lldbutil.run_to_source_breakpoint
can't handle the case where the breakpoint will be in a dlopen-ed
library, since it requires the breakpoint to have at least 1 location
before run. I fixed that by adding a parameter to say whether a
before run location is expected.

https://reviews.llvm.org/D45592 added a nice feature to be able to specify a breakpoint by a relative path. E.g. passing foo.cpp or bar/foo.cpp or zaz/bar/foo.cpp is fine. However, https://reviews.llvm.org/D68671 by mistake disabled the test that ensured this functionality works. With time, someone made a small mistake and fully broke the functionality.
So, I'm making a very simple fix and the test passes.

The code that figured out which breakpoints to delete was supposed
to set the result status if it found breakpoints, and then the code
that actually deleted them checked that the result's status was set.
The code for "break delete --disabled" failed to set the status if
no "protected" breakpoints were provided. This was a confusing way
to implement this, so I reworked it with early returns so it was less
error prone, and added a test case for the no arguments case.

Previously ignore counts were checked when we stopped to do the sync callback in Breakpoint::ShouldStop. That meant we would do all the ignore count work even when
there is also a condition says the breakpoint should not stop.
That's wrong, lldb treats breakpoint hits that fail the thread or condition checks as "not having hit the breakpoint". So the ignore count check should happen after
the condition and thread checks in StopInfoBreakpoint::PerformAction.
The one side-effect of doing this is that if you have a breakpoint with a synchronous callback, it will run the synchronous callback before checking the ignore count.
That is probably a good thing, since this was already true of the condition and thread checks, so this removes an odd asymmetry. And breakpoints with sync callbacks
are all internal lldb breakpoints and there's not a really good reason why you would want one of these to use an ignore count (but not a condition or thread check...)

At the moment nearly every test calls something similar to
`self.dbg.CreateTarget(self.getBuildArtifact("a.out"))` and them sometimes
checks if the created target is actually valid with something like
`self.assertTrue(target.IsValid(), "some useless text")`.
Beside being really verbose the error messages generated by this pattern are
always just indicating that the target failed to be created but now why.
This patch introduces a helper function `createTestTarget` to our Test class
that creates the target with the much more verbose `CreateTarget` overload that
gives us back an SBError (with a fancy error). If the target couldn't be created
the function prints out the SBError that LLDB returned and asserts for us. It
also defaults to the "a.out" build artifact path that nearly all tests are using
to avoid to hardcode "a.out" in every test.
I converted a bunch of tests to the new function but I'll do the rest of the
test suite as follow ups.

This patch fixes the column symbol resolution when creating a breakpoint
with the `move_to_nearest_code` flag set.
In order to achieve this, the patch adds column information handling in
the `LineTable`'s `LineEntry` finder. After experimenting a little, it
turns out the most natural approach in case of an inaccurate column match,
is to move backward and match the previous `LineEntry` rather than going
forward like we do with simple line breakpoints.
The patch also reflows the function to reduce code duplication.
Finally, it updates the `BreakpointResolver` heuristic to align it with
the `LineTable` method.

Explicitly consider the libraries reported on the initial rendezvous
breakpoint hit added. This is necessary on FreeBSD since the dynamic
loader issues only a single 'consistent' state rendezvous breakpoint hit
for all the libraries present in DT_NEEDED. It is also helpful on Linux
where it ensures that ld-linux is considered loaded as well
as the shared system libraries reported afterwards.

unittest2.expectedFailure in decorators.py.
Most process plugins (if not all) don't set hardware index for breakpoints. They even

It also adds assertions to be sure that a breakpoint site is hardware when this is required.
