Jim Ingham 723a1caa37 Fix the crashlog.py script's use of the load_address property.
This property is explicitly for use only in the interactive editor,
and NOT in commands.  It's use worked until we got more careful about
not leaving lldb.target lying around in the script interpreter.

I also added a quick sniff test for the save_crashlog command.

Fred Riss 06ea05a3fb [lldb/test] Fix TestDSYMSourcePathRemapping in the presence of symlnks
My main work directory is on a separate partition, but I usually access
it through a symlink in my home directory. When running the tests,
either Clang or make resolves the symlink, and the real path of the
test directory ends up in the debug information.

This confuses this test as LLDB is trying to remap the real path, but
the remapping description uses the path with the symlink in
it. Calling realpath on the source path when constructing the
remapping description fixes it.

Jason Molenda 836534f997 Add more detailed symbol type categorization, based on a swift patch by
Greg Clayton a few years ago.

My patch to augment the symbol table in Mach-O files with the
dyld trie exports data structure only categorized symbols as code
or data, but Greg Clayton had a patch to do something similar to
swift a few years ago that had a more extensive categorization of
symbols, as well as extracting some objc class/ivar names from the
entries. This patch is basically just Greg's, updated a bit and
with a test case added to it.

Jason Molenda f0a5af906b Merge in symbols from Mach-O dyld trie to the symbol table
In ObjectFileMachO we construct the symbol table from multiple
sources -- primarily the binary's nlist records, but when the nlist
symbols have been stripped, we would augment those with function
start address from the LC_FUNCTION_STARTS or eh_frame.  This patch
adds another source of symbols - the exported symbols that the
dynamic linker, dyld, uses at runtime from its trie structure.  This
provides us names and addresses for these functions/data.

This patch removes the code from ParseSymtab that would reject an
empty symbol table / nlist source.  It adds a new symbols_added
set which tracks the address of every symbol we've added to the
symtab.  We add symbols in most-information-ful order, and before
adding a symbol from less-informational-ful source (e.g.
LC_FUNCTION_STARTS with no function name), we check if that symbol
has already been added.

On targets with thumb code generation, instead of using the 0th bit
in these addresses in FunctionStarts (or now the trie entries), we
use the data field of FunctionStarts (formerly used to track if the
func_start should be added) and a flag for the trie entries to
encode this, and only store the actual addresses in the symbols_seen
and these vectors.

Raphael Isemann 53b135eeb4 [lldb][NFC] Refactor TestSafeFuncCalls.py
Summary:
This patch inlines all the single-line functions that we only use once in the test
and replaces the assertTrue with an assertEquals to improve the error message
when this test fails.

Tatyana Krasnukha a31130f6fc [lldb][testsuite] Create a SBDebugger instance for each test
Some tests set settings and don't clean them up, this leads to side effects in other tests.
The patch removes a global debugger instance with a per-test debugger to avoid such effects.

From what I see, lldb.DBG was needed to determine the platform before a test is run,
lldb.selected_platform is used for this purpose now. Though, this required adding a new function
to the SBPlatform interface.

Jim Ingham 3cd13c4624 Fix a race between lldb's packet timeout and the profile thread's usleep.
The debugserver profile thread used to suspend itself between samples with
a usleep.  When you detach or kill, MachProcess::Clear would delay replying
to the incoming packet until pthread_join of the profile thread returned.
If you are unlucky or the suspend delay is long, it could take longer than
the packet timeout for pthread_join to return.  Then you would get an error
about detach not succeeding from lldb - even though in fact the detach was
successful...

I replaced the usleep with PThreadEvents entity.  Then we just call a timed
WaitForEventBits, and when debugserver wants to stop the profile thread, it
can set the event bit, and the sleep will exit immediately.

Raphael Isemann fdea9a4ec9 [lldb] Remove license headers from all test source files
Summary:
Around a third of our test sources have LLVM license headers. This patch removes those headers from all test
sources and also fixes any tests that depended on the length of the license header.

The reasons for this are:

* A few tests verify line numbers and will start failing if the number of lines in the LLVM license header changes. Once I landed my patch for valid SourceLocations in debug info we will probably have even more tests that verify line numbers.
* No other LLVM project is putting license headers in its test files to my knowledge.
* They make the test sources much more verbose than they have to be. Several tests have longer license headers than the actual test source.

For the record, the following tests had their line numbers changed to pass with the removal of the license header:
    lldb-api :: functionalities/breakpoint/breakpoint_by_line_and_column/TestBreakpointByLineAndColumn.py
    lldb-shell :: Reproducer/TestGDBRemoteRepro.test
    lldb-shell :: Reproducer/TestMultipleTargets.test
    lldb-shell :: Reproducer/TestReuseDirectory.test
    lldb-shell :: ExecControl/StopHook/stop-hook-threads.test
    lldb-shell :: ExecControl/StopHook/stop-hook.test

Jim Ingham 4570f2c7cf Add a test for debugserver handling threads suspended from within a program.
Mach allows you to suspend and resume other threads within a program, so
debugserver has to be careful not to interfere with this when it goes to supend and
resume threads while stepping over breakpoints and calling functions.  Even
trickier, if you call a function on a suspended thread, it has to resume the
thread to get the expression to run, and then suspend it properly when done.

This all works already, but there wasn't a test for it.  Adding that here.

This same test could be written for a unix that supports pthread_{suspend,resume}_np, but
macOS doesn't support these calls, only the mach version.  It doesn't look like
a lot of Linux'es support this (AIX does apparently...)  And IIUC Windows allows
you to suspend and resume other threads, but the code for that would look pretty
different than this main.c.  So for simplicity's sake I wrote this test for Darwin-only.

Raphael Isemann b3a0c4d7dc [lldb] Replace assertTrue(a == b, "msg") with assertEquals(a, b, "msg") in the test suite
Summary:
The error message from the construct `assertTrue(a == b, "msg") ` are nearly always completely useless for actually debugging the issue.
This patch is just replacing this construct (and similar ones like `assertTrue(a != b, ...)` with the proper call to assertEqual or assertNotEquals.

This patch was mostly written by a shell script with some manual verification afterwards:
```
lang=python
import sys

def sanitize_line(line):
  if line.strip().startswith("self.assertTrue(") and " == " in line:
    line = line.replace("self.assertTrue(", "self.assertEquals(")
    line = line.replace(" == ", ", ", 1)
  if line.strip().startswith("self.assertTrue(") and " != " in line:
    line = line.replace("self.assertTrue(", "self.assertNotEqual(")
    line = line.replace(" != ", ", ", 1)
  return line

for a in sys.argv[1:]:
  with open(a, "r") as f:
    lines = f.readlines()
  with open(a, "w") as f:
    for line in lines:
      f.write(sanitize_line(line))
```

Summary: Moves lldbsuite tests to lldb/test/API.

This is a largely mechanical change, moved with the following steps:

```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```

lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.
