* Account for patterns in total tries
Specifying patterns for the word list will no longer cause progress to
go past 100%. Additionally, the GobusterDir transformations for file
extensions and backups will be applied after pattern expansion.
Fixes#405, #480, and #533
* Run backup detection on success only
This is done by re-arranging the code from exiting on channel close to
using the contexts and the results counters to signal the end of work
processing. A little more work is needed to prevent infinite loops
caused by devious services/misconfiguration and to expose to the cli the
ability to have patterns run on successful finds.
Fixes#298
* Prioritize stopping when the context is done
From the Go spec:
> If one or more of the communications can proceed, a single one that
> can proceed is chosen via a uniform pseudo-random selection.
Previously, this meant that some indeterminate amount of work could have
been completed after the context's cancel function had been called.
* Prevent recursion of discovery guess
Successful guesses from the wordlist or a pattern will have discovery
patterns generated based on them and successful discovery guesses will
not. Further processing should require human curation to avoid
automatically generating an unbounded amount of traffic.
Also fixes reading the wordlist from standard in by making it more like
reading from a file now that we have dynamic progress updates.
* Add option for arbitrary discovery patterns
* Test only patterns if provided a pattern file
* Update discover pattern option description
