Jim Ingham 05f10ae0d8 On Windows, the function name contains the return parameter, so
the test has to be "function name contains the name we used to specify
the breakpoint" not IS the name...

Dave Lee 779bbbf27f [lldb] Replace asserts on .Success() with assertSuccess()
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

Jim Ingham 1ff367dbb0 Fix Linux error in TestBreakInLoadedDylib.py.
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.

Jim Ingham 9a2e9c5db6 Add tests for the other variants of BreakpointCreateBySourceRegex.
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.

Walter Erquinigo 0a68443bd0 [source map] fix relative path breakpoints
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.

Jim Ingham 0018c7123b Fix "break delete --disabled" with no arguments.
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.

Jim Ingham 658f6ed152 Make ignore counts work as "after stop" modifiers so they play nicely with conditions
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...)

Raphael Isemann 54c2687292 [lldb] Introduce createTestTarget for creating a valid target in API tests
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.

Med Ismail Bennani 35ecfda01c [lldb/Symbol] Fix column breakpoint `move_to_nearest_code` match
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.
