This PR is a subset of #28563 which brings across 16 files (the easy half) that only contain Python 3 compatibility modifications. Once this PR is merged, we can rebase #28563 and focus our attention on the complex half.

@MattIPv4 You review of these changes please.

MattIPv4 · 2019-07-07T09:40:17Z

@cclauss What is the aim with this? Is support for 2.7 intended still, or is this a complete move to 3.x?

cclauss · 2019-07-07T09:48:27Z

Both Python and legacy Python must be supported.

MattIPv4 · 2019-07-07T09:53:16Z

@cclauss Is legacy Python simply regarded as 2.7 now and not older versions that were supported before?

cclauss · 2019-07-07T10:07:57Z

Yes. See BUILDING.md.

tools/gyp/PRESUBMIT.py

tools/gyp/pylib/gyp/__init__.py

Lgtm.

Since this drops support Python 2.6 and below I labelled it dont-land 10.x and 8.x, which document support for 2.6 in their BUILDING.md. Someone can correct that if I misunderstand.

AFAICT, there is a bug in core-validate-commit, see nodejs/core-validate-commit#65

You could use tools: as a sub-system to make Travis happy, it can be patched if necessary when this is landed.

sam-github · 2019-07-08T18:35:26Z

@nodejs/gyp Needs one more approval to land (or will have to wait 114 more hours...).

@cclauss FYI, your github profile and your commit lack identifying information. Its not absolutely required, but it is helpful to be able to attribute commits to specific humans.

How do we make progress on this? Are there any Pythonistas in the project that we should add as reviewers? @nodejs/python

sam-github · 2019-07-10T21:24:35Z

@bnoordhuis You may be the sole member of https://github.com/orgs/nodejs/teams/gyp that is still active on the project, PTAL

tools/gyp/tools/pretty_gyp.py

-      brace_diff = 0
-      if not COMMENT_RE.match(line):
+    if COMMENT_RE.match(line):
+      print(line)


Does this not change the behavior? Before, it used to strip '\r\n\t ' from the line?

It looks like this is still doing that at 126 - This just now prints the line if it matches the regex, otherwise strips - Unlike before where it stripped it if failed the regex immediately.
