refactor-nrepl 3.0

Changes

• (Part of #230): Parallelize various functionality
  • This will have a noticeable improvement in e.g. clj-refactor.el's cljr-slash performance.
• #291: The :ignore-errors option will be honored in more places, making refactor-nrepl more robust in face of files not particularly meant to be part of the AST corpus.
  • Examples: WIP files, Moustache template files, scripts.
• Upgrade Orchard
  • Worth emphasizing: now the following options are available https://github.com/clojure-emacs/orchard/tree/v0.7.0#configuration-options
  • They can make the refactor-nrepl experience simpler / more robust.
• Upgrade rewrite-clj
  • This fixes some features such as rename-file-or-dir.
• Reliability improvement: try using require prior to find-ns
  • This increases the chances that a namespace will be found, which in turns makes refactor-nrepl more complete/accurate.
• Replace Cheshire with clojure.data.json
• Build ASTs more robustly (by using locks, require, and ruling out certain namespaces like refactor-nrepl itself)
• Improve namespace-aliases performance and make it return more accurate results.
• Honor internal future-cancel calls, improving overall responsiveness and stability.

Bugs fixed

• #335: Strengthen resolve-missing against various edge cases.
• #289: Fix an edge-case with involving keywords that caused find-symbol to crash.
• #305: Don't put :as or :refer on their own lines in the ns form, when the libspec is so long it causes the line to wrap.
• clojure-emacs/clj-refactor.el#459: clean-ns should conform to the style guide: (:require in the ns form should be followed by a newline.
  • You can opt out via the new :insert-newline-after-require configuration option.
• #294: Properly skip uneval nodes when looking for the first/last sexp
• From now on, if you set the clojure.tools.namespace.repl/refresh-dirs, files outside said refresh-dirs won't be analyzed, resulting in safer, more efficient analysis.
