Installation
No libraries are required to run the final executable.
The golang tool dep was used to handle dependencies. Golang 1.9 was used during development.
Usage
The executable can be run in one of two modes :-
- Master - In this mode the executable awaits information from watchers, and collates the file listings into one master list.
- Watcher - In this mode a single file directory is monitored for any changes. Updates are forwarded via http POST command to the master.
Only one master should ever be active at a time - multiple watchers can be active.
Command line parameters
- -help Print command-line information.
- -mode Defines the mode. Valid options are 'watcher', 'master'.
- -refresh Specifies how often a watcher node will update the master.
- -wport Defines which port a watcher runs on. Must be unique per watcher.
- -mport Defines which port a master presents the collated information on.
Example
First, run your master : exp1 -mode=master -mport=90
Then, as many watchers as you like :
exp1 -mode=watcher -watch=c:\ -wport=8000exp1 -mode=watcher -watch=d:\ -wport=8001
Finally, go to http://localhost:90 to view the results.
In each mode, the executable will block: that is, the code will run eternally until an error occurs, or the executable is halted.
Improvements
- The code is hardwired to
localhost: configuration option to change this would be useful. - As commented in the code, there are a couple of areas of golang code that I feel could/should be improved.
- Performance at high watcher counts is untested 😊
