Always pass NODE_OPTIONS with max-http-header-size #5452

flotwig · 2019-10-24T16:58:45Z

Reverted in #5522

Originally meant for: 431 status code on stubbed XHR requests with large response in 3.5.0 #5431

User facing changelog

Fixes a regression in 3.5.0 where the maximum size of an HTTP header or cy.route() stub body was limited to 8kb and requests would fail with HTTP error 431.

Additional details

Passes --max-http-header-size=${1024 * 1024} in NODE_OPTIONS environment var from CLI
- Passing it as a CLI arg (the way we thought it worked) does not seem to work with vanilla Electron binary or with built Cypress binary, so this is the only way
- By ordering it before the user-supplied NODE_OPTIONS, the user can still override this via NODE_OPTIONS if they choose
Makes 4_xhr_spec e2e test go through CLI so it can run a test with this max http header size set
User's original NODE_OPTIONS are backed up and restored once Electron successfully launches so that node processes launched by Cypress on behalf of the user have desired NODE_OPTIONS

PR Review Checklist

If any of the following requirements can't be met, leave a comment in the review selecting 'Request changes', otherwise 'Approve'.

User Experience

The feature/bugfix is self-documenting from within the product.
The change provides the end user with a way to fix their problem (no dead ends).

Functionality

The code works and performs its intended function with the correct logic.
Performance has been factored in (for example, the code cleans up after itself to not cause memory leaks).
The code guards against edge cases and invalid input and has tests to cover it.

Maintainability

The code is readable (too many nested 'if's are a bad sign).
Names used for variables, methods, etc, clearly describe their function.
The code is easy to understood and there are relevant comments explaining.
New algorithms are documented in the code with link(s) to external docs (flowcharts, w3c, chrome, firefox).
There are comments containing link(s) to the addressed issue (in tests and code).

Quality

The change does not reimplement code.
There's not a module from the ecosystem that should be used instead.
There is no redundant or duplicate code.
There are no irrelevant comments left in the code.
Tests are testing the code’s intended functionality in the best way possible.

Internal

The original issue has been tagged with a release in ZenHub.

Hm, Mac kitchensink is failing because it only has support for Node 11. Since it's in dev mode, it's launching node instead of electron and failing because 11 doesn't have this option. Might be better to just figure out all the places where this can be explicitly passed and pass it...

EDIT: Actually, --max-http-header-size doesn't seem to have any impact when passed to the package app. It only works if supplied in NODE_OPTIONS, which is also the only documented way I could find to pass Node CLI options to Node.js.

It appears like appropriate tests were added and I was able to follow the changes in relation to the PR's functionality. The whitespace changes made it a little hard to discern for a single file, but not impossible. I imagine having those whitespace changes would be ideal given what they were.

I ran this branch in the services repo - where basically all of their tests were failing with this 431 error - they are now passing. I didn't review the code.

cli/lib/util.js

+    if (options.dev && nodeVersion < 12) {
+      // `node` is used when --dev is passed, so this won't work if Node is too old
+      logger.warn('(dev-mode warning only) NODE_OPTIONS=--max-http-header-size could not be set. See https://github.com/cypress-io/cypress/pull/5452')
+


Will the new max-header log in DEBUG logs for all of our users? Cause I'd like any new options to be logged in their DEBUG logs for future debugging.

It is not logged anywhere :/ But, it should always be passed, as this is the only condition where it wouldn't be.

This reverts commit 978d97e.
