tools: fix check-imports.py to match on word boundaries #33268

richardlau · 2020-05-06T16:38:55Z

check-imports.py was missing some unused using statements as it
was not matching on word boundaries (e.g. MaybeLocal was considered
a use of Local). Fix that and add some unit tests (which required
the script to be renamed to drop the - so it could be imported into
the test script).

Refs: #29226

Marking as blocked as now the script is fixed it reveals the following unused imports:

#33261 will fix the ones in src/node.cc. Anyone have opinions on the best way to fix the remainder commit-wise? Should we fix them all in one commit, or try to group them up (e.g. src/node_report.cc and src/node_report_module.cc are the report subsystem)? @nodejs/releasers would it be easier to backport if they were all fixed up under one pull request or under several smaller pull requests?

I've no idea why but the GitHub Actions run is only showing one file (src/node_process_object.cc):
https://github.com/nodejs/node/pull/33268/checks?check_run_id=650248933

Running C++ linter...
File "src/node_process_object.cc" does not use "HandleScope"
File "src/node_process_object.cc" does not use "Just"
Makefile:1329: recipe for target 'tools/.cpplintstamp' failed
make: *** [tools/.cpplintstamp] Error 1

The CI run (https://ci.nodejs.org/job/node-test-linter/34578/console) looks to agree with the list in the OP.

@nodejs/automation @nodejs/python PTAL

bnoordhuis

LGTM, thanks. The fix-ups should be done in the same commit, or in a commit preceding the changes to the python script, that way make test keeps passing (important for git bisect.)

In the absence of anyone advocating the fix ups be done in smaller commits and since @danbev applied the code fix ups in #33565 I've cherry-picked his commit over here and reordered so it comes first.
