NewServer with callbacks based on functional options for friendly APIs. Replaces NewUFS. Add .Debug() to return a Debug-enabled version of the FileServer. Remove -root and -debug flags, use functional options instead. Most likely will conflict with Harvey-OS#32.
Based on NewServer rather than NewUFS.
Use NewServer rather than NewUFS.
Add debug.Server which wraps a NineServer and logs before and after calling functions for the underlying server. Add Trace option to protocol.Server. Makes Harvey-OS#34 obsolete
Sloppy merge, should have tested build afterwards.
Server.Trace was replaced by Trace option.
Set trace for the various servers to no-op log by default. Users can then change the trace function using the Trace option.

There was a problem hiding this comment.
or, hey, in here,
tracer = func(string, ...interface{}) {}
for convenience, we can do that later.

I set tracer = nologf in NewServer, this seems like it should return an error if you try to pass nil as the tracer.
Should not be nil otherwise the *.Trace will return an error.
Forgot to s/File/file.

Any thoughts on merging this? I noticed that #39 duplicates some of this PR. |

We should look at merging this in. There are some conflicts due to more recent PRs being merged in first. |
