A Scalable, User-Friendly Source Control System.
771fa19f18
Summary:
The current `dott` library enforces `sh % "foo"` to output nothing. That's
done by checking in `__del__`. `__del__` is special and cannot raise exceptions
so the current code put exceptions in a "delayed" list and raise it later.
However, the "later" raise uses a new traceback that is useless.
This diff changes it to use `sys.exc_info` to save the traceback information
so we can re-raise with more accurate exception:
For example, the exception before looks like:
% python test-empty-t.py
Traceback (most recent call last):
File "test-empty-t.py", line 71, in <module>
sh % "cd .."
File "fbcode/scm/hg/tests/testutil/dott/shobj.py", line 151, in __mod__
return LazyCommand(command)
File "fbcode/scm/hg/tests/testutil/dott/shobj.py", line 28, in __init__
raise _delayedexception[0]
UnboundLocalError: local variable 'code' referenced before assignment
The `shobj.py` in traceback is pointless.
With the change, it now looks like:
% python test-empty-t.py
Traceback (most recent call last):
File "test-empty-t.py", line 71, in <module>
sh % "cd .."
File "fbcode/scm/hg/tests/testutil/dott/shobj.py", line 153, in __mod__
return LazyCommand(command)
File "fbcode/scm/hg/tests/testutil/dott/shobj.py", line 97, in __del__
autofix.eq(out, "", nested=1, fixfunc=_fixoutput)
File "fbcode/scm/hg/tests/testutil/autofix.py", line 74, in eq
fix = fixfunc(code, parse, lineno, parse(path))
UnboundLocalError: local variable 'code' referenced before assignment
