There are some problems with nyc:
* The coverage numbers aren't useful in our case because most of the
code is executed outside the test process (the test code is mostly
API client logic).
* nyc messes with line numbers, which makes it much harder to debug
problems.
* We're seeing frequent SIGABRT crashes while nyc is printing the
results table. I'm not sure if nyc is the cause of the crashes, or
if it's making a race condition worse, or if the crashes have
nothing to do with nyc, but we don't lose much by removing it so
we might as well see if the crash frequency improves.
Rewrite the `callAll` and `aCallAll` functions to support all
reasonable hook behaviors and to report errors for unreasonable
behaviors (e.g., calling the callback twice).
Now a hook function like the following works as expected when invoked
by `aCallAll`:
```
exports.myHookFn = (hookName, context, cb) => {
cb('some value');
return;
};
```
Rather than reinvent the wheel, use a well-tested library to parse and
write cookies. This should also help prevent XSS vulnerabilities
because the library handles special characters such as semicolon.
Previously Etherpad would not pass the correct client IP address through and this caused the rate limiter to limit users behind reverse proxies. This change allows Etherpad to use a client IP passed from a reverse proxy.
Note to devs: This header can be spoofed and spoofing the header could be used in an attack. To mitigate additional *steps should be taken by Etherpad site admins IE doing rate limiting at proxy.* This only really applies to large scale deployments but it's worth noting.
If mocha hangs after running the tests, hit Ctrl-C and wtfnode will
print open files, open sockets, running timers, and running intervals.
Adding an `after` function that closes/stops all of those things will
ensure that mocha exits when it finishes running the tests.
