They are global for the node for all future call trace flags, so it's not necessary to set them repeatedly with every request. Doing it once at startup also ensures we can't have race conditions when the user wants to change which trace patterns should be used (because requests are concurrent and patterns end up overwriting themselves repeatedly), and makes this changing of trace patterns much more straightforward: the user can just define the ones they want. The default function traces everything. In addition I have also added the tracer_flags option to make the trace flags configurable, excluding the tracer pid. |

= Cowboy Cowboy is a small, fast and modern HTTP server for Erlang/OTP. == Goals Cowboy aims to provide a *complete* HTTP stack in a *small* code base. It is optimized for *low latency* and *low memory usage*, in part because it uses *binary strings*. Cowboy provides *routing* capabilities, selectively dispatching requests to handlers written in Erlang. Because it uses Ranch for managing connections, Cowboy can easily be *embedded* in any other application. Cowboy is *clean* and *well tested* Erlang code. == Online documentation * https://ninenines.eu/docs/en/cowboy/2.1/guide[User guide] * https://ninenines.eu/docs/en/cowboy/2.1/manual[Function reference] == Offline documentation * While still online, run `make docs` * User guide available in `doc/` in PDF and HTML formats * Function reference man pages available in `doc/man3/` and `doc/man7/` * Run `make install-docs` to install man pages on your system * Full documentation in Asciidoc available in `doc/src/` * Examples available in `examples/` == Getting help * Official IRC Channel: #ninenines on irc.freenode.net * https://github.com/ninenines/cowboy/issues[Issues tracker] * https://ninenines.eu/services[Commercial Support]
