Trott · 2017-10-22T01:11:20Z

First commit seems fine. Not clear on how/why the second commit. Can you elaborate a bit?

refack · 2017-10-22T01:49:28Z

The original bug is caused by

node/tools/eslint/node_modules/ignore/ignore.js

Line 416 in 8e268c7

return (/^\\\\\?\\/.test(str) || /[^\x00-\x80]+/.test(str) ? str : str.replace(/\\/g, '/')

in ignore. This RegExp fails when there are non ASCII characters in the path. so it fails to "posix"ise the path
ignore slices the path by / then test east slice for a match exclusion with the exclusion rules
eslint has a default ignore rule to exclude any path starting with . so if the temp directories we create start with dot we don't need an extra rule, and it's not slice dependant.

@refack Thanks for the clear explanation. Does the bug only manifest on Windows? I've not seen it anywhere else... EDIT: Never mind, I see that the buggy code is indeed Windows-specific.

Trott

LGTM if CI is green. I dislike using .tmp instead of tmp but that's an aesthetic decision, and working around bugs is more important than accommodating my aesthetic preferences.

refack · 2017-10-22T02:11:05Z

The bug manifests only on Windows because the step that is sensitive to unicode (or UTF-8) is the conversion from \ to /.

Trott · 2017-10-22T11:24:46Z

I guess it makes sense to leave test/tmp* in .gitignore because those directories will still be hanging around after this commit lands in someone's clone.

Maybe it makes sense to add test/tmp* (and test/.tmp* because why not?) to the clean target in Makefile and vcbuild.bat so that there's a chance of removal of test/tmp* from .gitignore eventually? Could be a separate PR, especially if we think a fix might be coming to ignore.js and people might actively dislike the change to .tmp for whatever reason.

I'm a big believer in git clean -Xfd (Capital X to remove ignored files), but for those who are used to make targets will do...

P.S. a .gitignore cleanup/refactor in the works...

RE the third commit (25ff3343d326c4295f580db32e7d0c7b5a1a8127) I'm doing it semi blind, so would appreciate some extra manual validation.
Decided to un-document the vcbuild.bat command since it seems vestigial (does very little actual cleaning), and only relevant for release build scenarios.

Trott · 2017-10-22T15:13:22Z

Makefile

I think the indentation in the current Makefile makes more sense because this is a continuation of the previous line and not a new command.

gibfahn · 2017-10-22T17:44:47Z

test/common/index.js

Could you add a comment? Maybe something like:

// Eslint ignores directories beginning with '.' by default.

gibfahn · 2017-10-22T17:48:19Z

Makefile

I'm not sure we need this, if we never had it before, then why not just stick with the new one? (partly a question for @Trott )

If we are adding it (and it's already legacy) then could you add a comment saying # Remove this at some point

gibfahn · 2017-10-22T17:56:51Z

vcbuild.bat

So this is only used in a few places right?

node/vcbuild.bat

Lines 171 to 177 in 7a171fd

if "%target%"=="Clean" echo deleting %~dp0deps\icu

if "%target%"=="Clean" rmdir /S /Q %~dp0deps\icu

:no-depsicu

call :getnodeversion || exit /b 1

if "%target%"=="Clean" rmdir /Q /S "%~dp0%config%\node-v%FULLVERSION%-win-%target_arch%" > nul 2> nul

Agreed that it doesn't look like a user-facing thing.

Might have been once... Now it seems more like clean-release-artifacts. So, confusing.

gibfahn · 2017-10-22T17:58:23Z

.eslintignore

So how exactly does this make the ignoring more correct?

It's an ignore thing, it builds the exclusion regex based on this line (requiring a terminal /), then the directory itself is matched as test/addons/12_XFD (with no trailing /) so it passes and all it's children are enumerated (only they fail).
So the line pre PR is equivalent to test/addons/??_*/* and test/addons/??_* make it exclude the directories and not even enumerate their content.

Should this be backported to v6.x-staging? If yes please follow the guide and raise a backport PR, if not let me know or add the dont-land-on label.

This should likely be part of a batch update to eslint
