The main `maxctrl` function now does the cluster health checks and handles
the iteration over the host list. This solves the problem of how to
execute commands on multiple hosts while still allowing recursive calls
into the common functions.
This does not, however, solve the problem of how interconnected commands
across a set of servers are handled. One way to solve this would be to
offer a second main function, `maxctrl_cluster` which would call the
callback with a set of servers instead of a single server.
Minor refactoring to the core library to allow multiple calls from within
the same program.
Added --quiet option to silence output so that tests aren't so
verbose. Currently this only works on UNIX based systems.
The request-promise-native package adds support for request with native
promises. This is a convenient way to synchronize multiple HTTP requests.
The functions are changed to use promises to make testing easier. With
promises, the testing code can use the chai-as-promised library.
There are a few cases where doRequest is called with a callback that again
calls doAsyncRequest. With multiple hosts, this causes each command to be
propagated to all servers. This is a design flaw of the current multi-host
mode and needs to be changed.
Changed maxctrl.js to wait on the promises to silence some warnings if the
promise rejections are ignored.
All invocations into the common helper functions are now done through the
`maxctrl` function. This allows the program arguments to be passed to the
core as a parameter instead of reading them from global variables.
This helps with the implicit initialization that was done when the yargs
library was required which caused duplicated output.
Refactored the core functions so that they only process the argument
vector. The parsing of the argument vector is done in maxctrl.js where it
is more appropriate.
Making the invocation explicit should allow testing without actually
starting the process fromt the command line. Also returning a promise
allows chaining of commands for testing and verification.
