These tests were temporarily missing when the big Makefile

Greg Clayton 4f68c226a5 Fix ELF core file memory reading for PT_LOAD program headers with no p_filesz
Prior to this fix, ELF files might contain PT_LOAD program headers that had a valid p_vaddr, and a valid file p_offset, but the p_filesz would be zero. For example in llvm-project/lldb/test/testcases/functionalities/postmortem/elf-core/thread_crash/linux-i386.core we see:

Program Headers:
Index   p_type           p_flags    p_offset           p_vaddr            p_paddr            p_filesz           p_memsz            p_align

Prior to this fix if users tried to read memory from one of these addresses like 0x8048000, they would end up incorrectly reading from the next memory region that actually had a p_filesz which would be 0x00000000f778c000 in this case. This fix correctly doesn't include program headers with zero p_filesz in the ProcessELFCore::m_core_aranges that is used to read memory. I found two cores files that have this same issue and added tests.

Jonas Devlieghere f5687d7c12 Remove `bugreport` command
The bugreport command exists to create domain-specific bug reports.
Currently it has one implementation for filing bugs on the unwinder. As
far as we can tell, it has never been of use. Although not exactly the
same as the reproducers, it's a bit confusing to have two parallel
command trees for (kind of) the same thing.

Raphael Isemann e5814d78ce [lldb] Limit the amount of zeroes we use for padding when printing small floats
Summary:
We got a radar that printing small floats is not very user-friendly in LLDB as we print them with up to
100 leading zeroes before starting to use scientific notation. This patch changes this by already using
scientific notation when we hit 6 padding zeroes by default and moves this value into a target setting
so that users can just set this number back to 100 if they for some reason preferred the old behaviour.

This new setting is influencing how we format data, so that's why we have to reset the data visualisation
cache when it is changed.

Note that we have always been using scientific notation for large numbers because it seems that
the LLVM implementation doesn't support printing out the padding zeroes for them. I would have fixed
that if it was trivial, but looking at the LLVM implementation for this it seems that this is not as trivial
as it sounds. I would say we look into this if we ever get a bug report about someone wanting to have
a large amount of trailing zeroes in their numbers instead of using scientific notation.

Pavel Labath 418a272f4a [dotest] Avoid the need for LEVEL= makefile boilerplate
Summary:
Instead of each test case knowing its depth relative to the test root,
we can just have dotest add the folder containing Makefile.rules to the
include path.

This was motivated by r370616, though I have been wanting to do this
ever since we moved to building tests out-of-tree.

The only manually modified files in this patch are lldbinline.py and
plugins/builder_base.py. The rest of the patch has been produced by this
shell command:

Raphael Isemann 6897a814e6 [lldb] Add description to option completions.
Summary:
Right now our argument completions are rather cryptic for command options as they only list the letters:

```
(lldb) breakpoint set -
Available completions:
	-G
	-C
	-c
	-d
	-i
	-o
	-q
	-t
	-x
[...]
```

With the new completion API we can easily extend this with the flag description so that it looks like this now:

```
(lldb) breakpoint set -
Available completions:
	-G -- The breakpoint will auto-continue after running its commands.
	-C -- A command to run when the breakpoint is hit, can be provided more than once, the commands will get run in order left to right.
	-c -- The breakpoint stops only if this condition expression evaluates to true.
	-d -- Disable the breakpoint.
	-i -- Set the number of times this breakpoint is skipped before stopping.
	-o -- The breakpoint is deleted the first time it stop causes a stop.
	-q -- The breakpoint stops only for threads in the queue whose name is given by this argument.
	-t -- The breakpoint stops only for the thread whose TID matches this argument.
	-x -- The breakpoint stops only for the thread whose index matches this argument.
```

The same happens with --long-options now.

Pavel Labath 12a7e6c09c dotest: improvements to the pexpect tests
Summary:
While working on r370054, i've found it frustrating that the test output
was compeletely unhelpful in case of failures. Therefore I've decided to
improve that. In this I reuse the PExpectTest class, which was one of
our mechanisms for running pexpect tests, but which has gotten orhpaned
in the mean time.

I've replaced the existing send methods with a "expect" method, which
I've tried to design so that it has a similar interface to the expect
method in regular non-pexpect dotest tests (as it essentially does
something very similar). I've kept the ability to dump the transcript of
the pexpect communication to stdout in the "trace" mode, as that is a
very handy way to figure out what the test is doing. I've also removed
the "expect_string" method used in the existing tests -- I've found this
to be unhelpful because it hides the message that would be normally
displayed by the EOF exception. Although vebose, this message includes
some important information, like what strings we were searching for,
what were the last bits of lldb output, etc. I've also beefed up the
class to automatically disable the debug info test duplication, and
auto-skip tests when the host platform does not support pexpect.

This patch ports TestMultilineCompletion and TestIOHandlerCompletion to
the new class. It also deletes TestFormats as it is not testing anything
(definitely not formats) -- it was committed with the test code
commented out (r228207), and then the testing code was deleted in
r356000.

Raphael Isemann efb8b7b1ec [lldb] Fix and test completion for ambiguous long options
The refactoring patch for the option completion broke the completion
for ambiguous long options. As this feature was also untested (as
testing ambiguous options with the current test methods is impossible),
I just noticed now. This patch restores the old behavior and adds a
test for this feature.

Raphael Isemann 5edee822d2 [lldb] Allow partial completions to fix directory completion.
On the command line we usually insert a space after a completion to indicate that
the completion was successful. After the completion API refactoring, this also
happens with directories which essentially breaks file path completion (as
adding a space terminates the path and starts a new arg). This patch restores the old
behavior by again allowing partial completions. Also extends the iohandler
and SB API tests as the implementation for this is different in Editline
and SB API.

Jonas Devlieghere 27cb29a596 [dotest] Remove long running test "decorator" and re-enable tests.
Today I discovered the skipLongRunningTest decorator and to my surprise
all the tests were passing without the decorator. They don't seem to be
that expensive either, they take a few seconds but we have tests that
take much longer than that. As such I propose to remove the decorator
and enable them by default.

Jim Ingham 7049b0ad4d Stop-hooks weren't getting called on step-out. Fix that.
There was a little bit of logic in the StopInfoBreakpoint::PerformAction
that would null out the StopInfo once we had a completed plan so that the
next call to GetStopInfo would replace it with the StopInfoThreadPlan.

But the stop-hooks check for whether a thread stopped for a reason didn't
trigger this conversion.  So I added an API to do that directly, and then
called it where before we just reset the StopInfo.

Summary: We have been seeing increased reports of performance issue around large project and formatting std::function variables especially in functions signatures in back traces. There are some possible fixes but exploring those fixes may take time and it is better to temporarily disable the formatter due to its impact and re-enable it once we have a fix.

Adrian McCarthy 5f5379d076 Fix TestThreadSpecificBreakpoint on Windows
This test was frequently hanging on Windows, causing a timeout after
10 minutes.  The short delay (100 microsecond) in the sample program
could cause a deadlock in the Windows thread pool, as I've explained
in the test program's comments.

Now that it doesn't hang, it passes reliably, so I've removed the
Windows-specific XFAIL.

I've tried to clarify the comments in TestThreadSpecificGBreakpoint.py
by eliminating some redundancy and typos, and I simplified away a
couple unnecessary assignments.

Jonas Devlieghere 07b1a2b9ae Fix completion for functions in anonymous namespaces
I was going through some of the old bugs and came across PR21069 which I
was able to reproduce. The issue is that we match the regex `^foo`
against the `DW_AT_name` in the DWARF, which for our anonymous function
is indeed `foo`. However, when we get the function name from the symbol
context, the result is `(anonymous namespace)::foo()`. This throws off
completions, which assumes that it's appending to whatever is already
present on the input, resulting in a bogus
`b fooonymous\ namespace)::foo()`.

Jan Kratochvil 2b38951799 [lldb] Increase testsuite packet-timeout 5secs -> 1min
rL357954 did increase `packet-timeout` 1sec -> 5secs. Which is IMO about the
maximum timeout reasonable for regular use. But for testsuite I think the
timeout should be higher as the testsuite runs in parallel and it can be run
even on slow hosts and with other load (moreover if it runs on some slow arch).

I have chosen 60 secs, that should be enough hopefully.  Larger value could
make debugging with hanging `lldb-server` annoying.

This patch was based on this testsuite timeout:

Pavel Labath ee74c9e5fd LLGS: fix tracking execve on linux
Summary:
Due to a logic error, lldb-server ended up asserting/crashing every time
the debugged process attempted an execve(). This fixes the error, and
extends TestExec to work on other platforms too. The "extension"
consists of avoiding non-standard posix_spawn extensions and using the
classic execve() call, which should be available on any platform that
actually supports re-execing. I change the test decorator from
@skipUnlessDarwin to @skipIfWindows.

Skip decrement-and-recompute for trap handlers in

return address to the start of the return trampoline.

Parse the 'S' flag for signal handlers from eh_frame augmentation, and
propagate it to the unwind plan.

Raphael Isemann 2bc8ab6852 [lldb] Make TestDeletedExecutable more reliable
Summary:
It seems that calling Popen can return to the caller before the started process has read all the needed information
from its executable. This means that in case we delete the executable while the process is still starting up,
this test will create a zombie process which in turn leads to a failing test. On my macOS system this happens quite frequently.

This patch fixes this by letting the test synchronize with the inferior after it has started up.
