"Error (error) while connecting" and "task-id is nil" #78

Closed PythonNut closed 6 years ago

PythonNut commented 8 years ago

With python3.5, and a newly installed traad-server.

Steps

Here are the steps I used to reproduce:

  1. emacs24.5 -Q test.py
  2. M-x traad-install-server RET
  3. M-x traad-open RET RET

  4. Enter the following code:

    def foo(this_is_a_test):
 return this_is_a_test
  5. Place the cursor on either instance of this_is_a_test
  6. M-x traad-rename RET replaced_name RET

Result

  1. The following is printed in the echo-area: REQUEST [error] Error (error) while connecting to http://127.0.0.1:38213/refactor/rename. and Rename started with task-id nil.
  2. No other changes to the buffer are apparent.
  3. In addition, here are the contents of the *traad-server* buffer:

Minor note: I fail. This issue is a duplicate of #76.

This looks very much like it's the result of a known problem with request.el. The only real fix right now is to manually patch request.el; the details are in the PR linked in the issue report.
