intro

programs to help test styx/9p servers for correct behaviour.

file servers are not hard to write, but there are some corner cases
that need to be handled correctly.  styxtest checks whether a
styxserver (reachable by dial(2)) reacts properly to styx requests.
styxtest also checks things that are handled by styxservers.m, not
all styx servers use that library.

to use styxtest, run it with an address address as parameter.  this
will perform only basic tests.  several command-line parameters allow
you to specify paths that styxtest will perform styx messages
on, such as reads, writes, stats.  for example:

styxtest net!localhost!1234 nosuchfile does/not/exist createfile newfile createdir newdir file testfile dir testdir

the full table and requirements for the the file (plain file) or
directory:

key             value
---------------------
createfile	name of file (not full path!) that does not exist and can be created and removed.
createdir	like createfile.
unremovablefile	path to plain file that exists and cannot be removed.
unremovabledir	like unremovablefile.
nosuchfile	path to non-existent file.
file		plain existing file that has read permissions.
filero		plain existing file with read-only (not write) permission.
filew		plain existing file with at least write permission.
filex		plain existing file with at least read & execute permission.
filenoperm	plain existing file with no permission.
filenonempty	plain existing file with read permission of at least 2 bytes.
dir		existing directory with read permission.
dirw		existing directory with at least write permission.

some styx servers might need to be tested for extra (sequences of)
styx messages.  others might need fewer tests.  modifying the
styxtest.b (the source code) seems the appropriate way to do this.
each test is very straight-forward in limbo code, implementing a
language to write tests in (specifying styx messages to write and
expect) does not seem worth the trouble.

install

modify "mkconfig" or make sure $ROOT is set.  run "mk" and
"mk install" to compile and install the files.

when building from within inferno, insert SYSHOST=Inferno and ROOT=
in the mk invocations to override the values in the mkconfig.

todo

• test ORCLOSE
• test whether stat returns length 0 after open with OTRUNC?
• test concurrent operations on fid, e.g. two reads/writes. flush too then (for asynchronous styx servers).
