module: fix error first line col offset #2867

tflanagan · 2015-09-14T22:38:32Z

Rehash of nodejs/node-v0.x-archive#25342 with noted corrections.

Fixes #2860, nodejs/node-v0.x-archive#9445

I've also created another variant of this solution by adding a "\n" to the wrapper and setting the lineOffset property to -1, re: tflanagan@9d8e6a9

kenany · 2015-09-14T23:21:46Z

I feel like @brendan0powers's authorship should be preserved here.

tflanagan · 2015-09-14T23:23:57Z

👍

Just looking for things to do (this seemed rather important)

brendanashworth · 2015-09-15T03:18:28Z

Are there any side effects of using the second commit (tflanagan@9d8e6a9)? It seems way simpler.

 - `filename`: allows you to control the filename that shows up in any stack
  traces produced.
+- `lineOffset`: allows you to add an offset to the line number that is


Need to also update docs on Script constructor

I've updated the docs in two places with the lineOffset and columnOffset parameters, and also added a missing filename and timeout parameter listings.

I agree with @brendanashworth that the other commit looks much simpler. Does it cause any issues on Windows?

tflanagan · 2015-10-08T15:11:01Z

bump for LTS? Don't want this PR to end up like @brendan0powers's

brendanashworth · 2015-10-10T01:17:18Z

@tflanagan does tflanagan@489b5b4 cause any issues (perhaps windows)? I think this should be pushed instead of the other bigger commits. But this would be a candidate for LTS back-porting anyways.

tflanagan · 2015-10-10T04:46:24Z

I've beening running it on windows for over 3 weeks without issues, granted any issue would only show if an error occured

brendanashworth · 2015-10-10T05:07:44Z

@tflanagan could you push only that commit to this PR then? Then we can review and run the CI.

tflanagan · 2015-10-12T13:57:12Z

@brendanashworth okay, i've rebased/amended/pushed it down to one commit with the NL approach.

$ vcbuild test nosign passed all tests

@tflanagan I'm interested in getting this landed. Would you mind rebasing?

tflanagan · 2015-11-20T19:31:06Z

@cjihrig Rebased, running new tests now, will force push shortly

tflanagan · 2015-11-20T19:53:43Z

@cjihrig Done.

Besides for those pesky flaky Buffer tests, it passes local tests fwiw

Edit: Fixed the docs

@cjihrig Looks like it passed! :) 💯

💚 from the CI. Nice. Landing.

Because Node modules are wrapped, errors on the first line of a file leak the wrapper to the user and report the wrong column number. This commit adds a line break to the module wrapper so that the first line is treated the same as all other lines. To compensate for the additional line, a line offset of -1 is also applied to errors. Fixes: #2860 PR-URL: #2867 Reviewed-By: Colin Ihrig <cjihrig@gmail.com>

In dfee4e3, the module wrapper and line offset used when wrapping module code was changed to better report errors on the first line of modules. However, that commit did not update the runInThisContext() call used to execute the core modules, so their error line numbers have been off by one.
