Walter Erquinigo 881af6eb00 [lldb-vscode] Fix TestVSCode_module
For some reason this works on the original author's machine, but not on my. So I'm using a safer approach of using an unstripped dynamic library to place breakpoints on. The author was placing a breakpoint on the main symbol of a stripped library and for some reason it worked on their machine, but it shouldn't have...

Walter Erquinigo 74ab1da028 Redo of Add terminateCommands to lldb-vscode protocol
Summary:
This redoes https://reviews.llvm.org/D79726 and fixes two things.
- The logic that determines whether to automatically disconnect during the tear down is not very dumb compared to the original implementation. Each test will determine whether to do that or not.
- The terminate commands and terminate event were being sent after the disconnect response was sent to the IDE. That was not good, as VSCode stops the debug session as soon as it receives a disconnect response. Now, the terminate event and terminateEvents are being executed before the disconnect response is sent. This ensures that any connection between the IDE and lldb-vscode is alive while the terminate commands are executed. Besides, it also allows displaying the output of the terminate commands on the debug console, as it's still alive.

Walter Erquinigo 0a9e7d0b6b [vscode] set default values for terminateDebuggee for the disconnect request
Summary:
Recently I've noticed that VSCode sometimes doesn't send the terminateDebuggee flag within the disconnectRequest,
even though lldb-vscode sets the terminateDebuggee capability correctly.
This has been causing that inferiors don't die after the debug session ends, and many users have reported issues because of this.

An easy way to mitigate this is to set better default values for the terminateDebuggee field in the disconnect request.
I'm assuming that for a launch request, the default will be true, and for attach it'll be false.

Walter Erquinigo 83725822c5 [lldb-vscode] Add an option for loading core files
Summary:
Currently loading core files on lldb-vscode is broken because there's a check in the attach workflow that asserts that the PID is valid, which of course fails for this case.
Hence, I'm adding a "coreFile" argument for the attach request, which does the work correctly.

I don't know how to test it effectively so that it runs on the buildbots and the debugger can in fact makes sense of it. Anyway, the change has been relatively simple.

[lldb-vscode] Correctly return source mapped breakpoints for setBreakpoints request

Walter Erquinigo e796c77b26 [lldb-vscode] Correctly return source mapped breakpoints for setBreakpoints request
Summary:
When using source maps for a breakpoint, in order to find the actual source that breakpoint has resolved, we
need to use a query similar to what CommandObjectSource::DumpLinesInSymbolContexts does, which is the logic
used by the CLI to display the source line at a given breakpoint. That's necessary because from a breakpoint
location you only have an address, which points to the original source location, not the source mapped one.

in the setBreakpoints request handler, we haven't been doing such query and we were returning the original
source location, which was breaking the UX of VSCode, as many breakpoints were being set but not displayed
in the source file next to each line. Besides, clicking the source path of a breakpoint in the breakpoints
view in the debug tab was not working for this case, as VSCode was trying to open a non-existent file, thus
showing an error to the user.

Ideally, we should do the query mentioned above to find the actual source location to respond to the IDE,
however, that query is expensive and users can have an arbitrary number of breakpoints set. As a simpler fix,
the request sent by VSCode already contains the full source path, which exists because the user set it from
the IDE itself, so we can simply reuse it instead of querying from the SB API.

I wrote a test for this, and found out that I had to move SetSourceMapFromArguments after RunInitCommands in
lldb-vscode.cpp, because an init command used in all tests is `settings clear -all`, which would clear the
source map unless specified after initCommands. And in any case, I think it makes sense to have initCommands
run before anything the debugger would do.

Greg Clayton 5998aceda9 Have lldb-vscode update the currently selecte thread and frame when it receives a "scopes" request.
Summary: The IDE has no packets that are sent to lldb-vscode that say which thread and frame are selected. The only way we know is we get a request for variables for a stack frame via a "scopes" request. When we receive this packet we make that thread and frame the selected thread and frame in lldb. This way when people execute lldb commands in the debug console by prefixing the expression with the backtick character, we will have the right thread and frame selected. Previously this was not updated as new stack frames were selected.

Walter Erquinigo a515fd01a4 [lldb-vscode] fix breakpoint result ordering
Summary:
The DAP specifies the following for the SetBreakpoints request:

  The breakpoints returned are in the same order as the elements of the 'breakpoints' arguments

This was not followed, as lldb-vscode was returning the breakpoints in a different order, because they were first stored into a map, and then traversed. Of course, maps normally don't preserve ordering.

See this log I captured:

  -->
  {"command":"setBreakpoints",
   "arguments":{
     "source":{
       "name":"main.cpp",
       "path":"/Users/wallace/fbsource/xplat/sand/test-projects/buck-cpp/main.cpp"
     },
     "lines":[6,10,11],
     "breakpoints":[{"line":6},{"line":10},{"line":11}],
     "sourceModified":false
   },
   "type":"request",
   "seq":3
  }

  <--
  {"body":{
     "breakpoints":[
       {"id":1, "line":11,"source":{"name":"main.cpp","path":"xplat/sand/test-projects/buck-cpp/main.cpp"},"verified":true},
       {"id":2,"line":6,"source":{"name":"main.cpp","path":"xplat/sand/test-projects/buck-cpp/main.cpp"},"verified":true},
       {"id":3,"line":10,"source":{"name":"main.cpp","path":"xplat/sand/test-projects/buck-cpp/main.cpp"},"verified":true}]},
     "command":"setBreakpoints",
     "request_seq":3,
     "seq":0,
     "success":true,
     "type":"response"
  }

As you can see, the order was not respected. This was causing the IDE not to be able to disable/enable breakpoints by clicking on them in the breakpoint view in the lower corner of the Debug tab.

This diff fixes the ordering problem. The traversal + querying was done very fast in O(nlogn) time. I'm keeping the same complexity.

I also updated a couple of tests to account for the ordering.

2020-03-20 19:24:51 -07:00
Hector Diaz 4ec6ebabfc [lldb-vscode] Add inheritEnvironment option
Summary:
If no custom launching is used, lldb-vscode launches a program with an empty environment by default. In some scenarios, the user might want to simply use the same environment as the IDE to have a set of working environment variables (e.g. PATH wouldn't be empty). In fact, most DAPs in VSCode have this behavior by default. In other cases the user definitely needs to set their custom environment, which is already supported. To make the first case easier for the user (e.g. not having to copy the PATH to the launch.json every time they want to debug simple programs that rely on PATH), a new option is now offered. inheritEnvironment will launch the program copying its own environment, and it's just a boolean flag.

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))
