helics's Issues

New Relic no longer supports their C SDK

We weren't seeing our metrics show up on their dashboard. After much debugging and back&forth, they discovered the problem on their side. They said that the C SDK is broken & they aren't going to fix it.

cabal package for 0.5.0 is missing Network/Helics.hs

It looks like src/ is missing Network/Helics.hs & other files, when downloaded from hackage, so it can't be built. I think it's because cabal sdist is only packaging up the dummy code, but not the real implementation due to the default value of the dummy flag.

Allow manually registering errors.

It looks like the only way errors are currently registered is if there is an uncaught exception in a transaction. I would like to be able to create errors for other reasons (such as 4xx/5xx status codes, etc.), and probably provide custom details about the error.

Also, thanks for creating helics! It's very useful!

Installation

Sorry for asking a question here, but would you mind offering some guidance for installing relics in a new application?

Expose ability to set transaction names manually

For the WAI middleware, I would like to be able to alter the transaction name, but it sets it automatically. Also, it would be nice if you could expose the TransactionId in a way that doesn't error out if the helics middleware is missing, for example:

lookupTransactionId :: Request -> Maybe TransactionId

File descriptors exhaustion

Hi,

In the getPages function, you're not closing the file descriptor after reading the data. In a loop, this causes the file descriptors to be exhausted: https://github.com/philopon/helics/blob/master/src/Network/Helics/Foreign/System.hsc
