lib: fix code cache generation

e7f710c broke the code cache generation since internalBinding
is now passed in through the wrapper and cannot be redeclared.
This patch fixes that.

test: run code cache test by default and test generator

Add the code cache tests to the default test suite, and test
the bookkeeping when the binary is not built with the code cache.
Test the code cache generator to make sure we do not accidentally
break it - until we enable code cache in the CI.

Checklist

make -j4 test (UNIX), or vcbuild test (Windows) passes

test/code-cache/test-code-cache.js

Remove "not" ?

refack

LGTM with nit addressed

refack · 2018-10-24T17:25:17Z

test/code-cache/test-code-cache-generator.js

Prefer assert.ok
Is there anything else we can test about the file? Maybe that it has the string static uint8_t internal_bootstrap_cache_raw[]?

Addressed nits and added tests for verifying node::DefineCodeCache() and node::DefineCodeCacheHash() are defined in the generated code.

Thank you!

Hmm, CI was not happy, I'll investigate

Rebased and added logs when the tools/generate_code_cache.js command fails (somehow when the child process fails (child.status !== 0), child.error is still null..is that a child process bug?)

CI: https://ci.nodejs.org/job/node-test-pull-request/18189/

EDIT: --without-intl implying no inspector is intentional: #12758

joyeecheung · 2018-10-29T07:16:35Z

Apparently inspector is not available in the withoutintl job (cc @refack is that intentional?)..skipped the inspector modules when inspector is not available.

CI: https://ci.nodejs.org/job/node-test-pull-request/18196/

joyeecheung · 2018-10-29T11:23:39Z

trace events are also unavailable in withoutintl jobs..fixed the cannotUseCache list again

So the resume build is green: https://ci.nodejs.org/job/node-test-pull-request/18204/
Although previously there were two occurrence of SSL routines:ssl3_get_record:decryption failed or bad record mac:../deps/openssl/openssl/ssl/record/ssl3_record.c:469: see #23913

I am leaning towards that's a irrelevant flake.

joyeecheung · 2018-10-29T16:18:41Z

@refack @cjihrig @targos Can you take another look? (not too much has changed since the initial iteration, though, mostly just skipping creating cache for modules that are not available in withoutintl jobs)

lib/internal/bootstrap/cache.js

  'internal/bootstrap/node'
 ].concat(depsModule);

+if (process.config.variables.v8_enable_inspector !== 1) {


May be worthwhile including a quick comment with these that says why they cannot use the cache, just so it's clear to folks coming along later.
