http: fix parsing of binary upgrade response body #17806

bnoordhuis · 2017-12-21T15:38:10Z

Fix a bug where a connection upgrade response with a Transfer-Encoding
header and a body whose first byte is > 127 causes said byte to be
dropped on the floor when passing the remainder of the message to
the 'upgrade' event listeners.

Fixes: #17789

lib/_http_client.js

Before anyone asks - yes, these could be constants, please suggest good names. :-)

(They don't have names in http_parser either though.)

Just made these up on the spot. Feel free to ignore. How about kSkipBodyAsUpgrade, kSkipBodyNoUpgrade... and I don't know for the 0 case.

lib/_http_client.js

Removed because not very useful and slightly misleading - this is not inside the agent.

lib/_http_server.js

Bogus comment, removed.

bnoordhuis · 2017-12-21T15:42:38Z

lib/_http_common.js

Slightly wrong comment, removed.

This callback and the one passed to listen could also be wrapped in common.mustCall.

Is this ready to land? Or do you want to fix the nits before this PR gets landed? @bnoordhuis

Rebased + new CI: https://ci.nodejs.org/job/node-test-commit/15534/

I've incorporated the comments about the test. I decided to leave the constants unnamed.

MylesBorins · 2018-02-27T06:10:52Z

Should this be backported to LTS? It lands cleanly on 8.x but will need a manual backport to v6.x

bnoordhuis · 2018-02-27T09:06:34Z

Yes, should be back-ported. I'll look into the v6.x back-port.

jeroenvollenbrock · 2018-04-11T21:04:22Z

@gibfahn Is there any reason this one was not included in 8.10.0? I can confirm the bug persists in node 8.11.1 :)

@jeroenvollenbrock not sure why it was missed... I've landed it on staging

@bnoordhuis did you have a chance to look into the 6.x backport?

@lpinca @MylesBorins it looks like Node 10.14.1 has a regression and this problem has snuck back into the release. This gist can consistently reproduce the error: https://gist.github.com/shellscape/2020916f92be5d61f4d411fb6d2bce61

Note that stepping back down to any 10.x version lower than 10.14.0 does not reproduce the error.

lpinca · 2018-12-11T14:20:42Z

@shellscape none of these commits https://github.com/nodejs/node/blob/master/doc/changelogs/CHANGELOG_V10.md#2018-11-29-version-10141-dubnium-lts-mylesborins seem related.

Try to reproduce it only with core modules. This fix landed with regression tests so chances are the issue you are experiencing is different / not in node core.

shellscape · 2018-12-11T14:23:42Z

@lpinca indeed, which baffled me. we've spun up brand new containers to verify the issue was isolated to 10.14.x. same containers from scratch with 10.13.x are completely fine.

MylesBorins · 2018-12-11T14:35:01Z

I'll dig into the repro and see what's going on

shellscape · 2018-12-11T14:37:34Z

@MylesBorins much appreciated. if you end up needing that in a separate repository, say the word and it shall be done.

BridgeAR · 2018-12-11T14:42:10Z

@shellscape would you be so kind and open a new issue about this with as much information as possible? That way it's easier to track the progress :)

shellscape · 2018-12-11T14:43:29Z

@BridgeAR I'll do my best, please don't nuke it right away if there's something lacking, happy to clean it up to spec. It'll be my first Node org issue.

BridgeAR · 2018-12-11T14:50:05Z

Don't worry, we normally only close an issue if they it's resolved, not a core issue or in the wrong repository.

As @lpinca pointed out, it's best to try to reduce the test case further by removing any third party modules. That way looking into it becomes much easier.

shellscape · 2018-12-11T14:54:33Z

@BridgeAR #24958. Trying to reproduce this with core modules is a bit beyond my range of ability. Gave it a shot, but there's a lot of knowledge needed to reproduce the same conditions that I apparently don't have as yet.
