* allow serviceData to override cacheSeconds with a longer value
* prevent [endpoint] json cacheSeconds property exceeding service default
* allow ShieldsRuntimeError to specify a cacheSeconds property
By default error responses use the cacheLength of
the service class throwing the error.
This allows error to tell the handling layer the maxAge
that should be set on the error badge response.
* add customExceptions param
This
1. allows us to specify custom properties to pass to the exception
constructor if we throw any of the standard got errors
e.g: `ETIMEDOUT`, `ECONNRESET`, etc
2. uses a custom `cacheSeconds` property (if set on the exception)
to set the response maxAge
* customExceptions --> systemErrors
* errorMessages --> httpErrors
* add base class for Graphql APIs
* add GithubAuthV4Service + updates to GH token pool
* update github forks to use GithubAuthV4Service
* rename GithubAuthService to GithubAuthV3Service
This pull request closes#2551: making sure that the keywords don't already appear in the example's title.
I also added validation that checks that they are at least two characters long, as this is enforced by the homepage when type your search.
The route helper functions are fairly well isolated from the rest of BaseService, with a few convenient entry points. They are easier to test in isolation.
The way the code was written before, `pathToRegexp` was invoked once for every request, which seems inefficient.
`route` was validated when it was used, though it seems more helpful to validate it up front.
This breaks out `_makeFullUrl`, `_regex`, `_regexFromPath` into new helper functions `makeFullUrl`, `assertValidRoute`, `prepareRoute`, and `namedParamsForMatch`.
It adds validation to route, and updates the services without patterns to include one, in order to pass the new validation rules.
