Get test/types tests passing on remote targets

[vharron]

Summary

redirecting output to a path that will work well on host or target.
copying file from output location to location on local host that
test will read from

Why we don't need mkdir.. put-file commands in non-debug configurations?

inside?

You may use "platform process launch" here in order to make it work either locally or remotely.

[vharron]

Looks like I got my diff backwards *blush*

[vharron]

Uses remote working directory for stdout redirect.

Better chance of working on Windows.

test/types/AbstractBase.py

You may use assertIsNotNone here.

It should not be a big deal but it seems lldb.remote_platform_working_dir is considered to be a main root directory and lldb.remote_platform.GetWorkingDirectory is a single test root. So, lldb.remote_platform.GetWorkingDirectory() might be a slightly more fine-grained option here.

s/process launch/platform process launch ?

Could you extract this logic into a separate method to use it here and within generic_type_tester?

[zturner]

test/types/AbstractBase.py

93–95

For portability this should use the python tempfile module, and also it should not use hardcoded paths like /foo

177–180

Same as above.

Can you use

os.path.join(lldb.remote_platform_working_dir, "lldb-stdout-redirect.txt")

[vharron]

refactored process_launch_o into separate function
using os.path.join instead of string.format
using assertIsNotNone(

instead of assertNotEqual(None,

using lldb.remote_platform.GetWorkingDirectory()

instead of using lldb.remote_platform_working_dir

[zturner]

Would you mind doing the temp file changes too? It wasn't your code that
did it with hardcoded paths, but since you're in there anyway, maybe it's a
quick fix?

[vharron]

I don't see the path you're talking about.

[zturner]

The one you removed then added back in the first and second patch set. It
was /tmp/golden_file.txt or something

[zturner]

I think because it was removed then added back. It was in the diff of diff
1 vs. diff 2. Anyway it's no big deal if it's not easy
