This PR switches the Nomad repository from using govendor to Go modules for managing dependencies. Aspects of the Nomad workflow remain pretty much the same. The usual Makefile targets should continue to work as they always did. The API submodule simply defers to the parent Nomad version on the repository, keeping the semantics of API versioning that currently exists. |

go-retryablehttp
The retryablehttp
package provides a familiar HTTP client interface with
automatic retries and exponential backoff. It is a thin wrapper over the
standard net/http
client library and exposes nearly the same public API. This
makes retryablehttp
very easy to drop into existing programs.
retryablehttp
performs automatic retries under certain conditions. Mainly, if
an error is returned by the client (connection errors, etc.), or if a 500-range
response code is received (except 501), then a retry is invoked after a wait
period. Otherwise, the response is returned and left to the caller to
interpret.
The main difference from net/http
is that requests which take a request body
(POST/PUT et. al) can have the body provided in a number of ways (some more or
less efficient) that allow "rewinding" the request body if the initial request
fails so that the full request can be attempted again. See the
godoc for more
details.
Example Use
Using this library should look almost identical to what you would do with
net/http
. The most simple example of a GET request is shown below:
resp, err := retryablehttp.Get("/foo")
if err != nil {
panic(err)
}
The returned response object is an *http.Response
, the same thing you would
usually get from net/http
. Had the request failed one or more times, the above
call would block and retry with exponential backoff.
For more usage and examples see the godoc.
