The old version would mistakenly try to release the lock if there was
error in acquiring it.

This code used to assume that all arguments were strings.
It was always wrong (create was passed as '0' or '1' rather
than as 0 or 1) but this was somehow masked.  When I added
readonly, things broke.  The solution is that winserver.py
ha a convention that an argument starting with '=' is
evaluated as an expression, and _startserver in testZEO's
WindowsConnectionText uses this for the create and readonly
args.

wide xterm or emacs window.  So now, when using Python 2.3 or later,
the textwrap module is used to wrap the message line, indenting
subsequent lines past the timestamp.  Details and tracebacks are left
alone.

Add a LOG call to ConnectionTests.setUp().

Add tests for the ClientStorage read_only and read_only_fallback
features.  Note that the latter feature is not completely working yet;
the reconnect feature doesn't work, so it's of questionable value for
now (though it *does* connect to a read-only storage whe no read-write
storage is available).

read_only_fallback option of ClientStorage.

Unfortunately, this still doesn't work completely; as shown by some
disabled tests that I'll check in shortly, the reconnect feature is
still broken.  But it's weekend time, and I need a checkpoint to keep
my own sanity.

"ClientStorage <pid>", use "ClientStorage:<pid>".

Also log a message when a ClientStorage instance is created, showing
the pid, the read_only and read_only_fallback parameters, and the
storage name.

Also log some more things: the retry of the register() call with
read_only=1, the notifyConnected call,

Also clean up a few comments and docstrings, removing one XXX that
seems out of date.

Also change the _tpc_cond.wait() method call into a wait(30).  That
way it is interruptable.

StorageServer class, instead of "ZEO Server:<pid>", use
"StorageServer:<pid>".  In the ZEOServer class, instead of "ZEO
Server:<pid>:<name>", use "ZEOStorage:<pid>:<name>".

Also log a message when a StorageServer instance is created, showing
the pid, the read_only parameter, the storage names, and for each
storage whether it is RO (read-only) or RW (read-write).

Also clean up a few comments, removing one XXX that seems out of
date, and use %r instead of %s in some log messages.

"ZEO Server", use "ZEO/start.py".  There was one (PANIC) log message
that used "z2"; changed that one to "ZEO/start.py" as well.

is simply to clear asyncore's socket_map after the fork.

changed and the hotshot invocation wasn't changed along.  Untested.

Add a send_call() method that computes a new msgid and hands the
message off to the smac layer.  Uses __msgid_lock()

call() still uses __call_lock, but callAsync() does not.  callAsync()
does not use any lock beyond what send_call() does.

each time round the loop (with a 30 sec. timeout).

should fix the problem that messages from different processes or
threads could be intermingled.  The code was rewritten to build up the
lines of the error message in a list which is joined by "\n"
characters at the end.

values that connect_ex() may return when we're connected).  This seems
to resolve the last hangs observed on Win2K.  There are still
(unrelated) hangs on Win98 though.

read-write connection is not available.  This refactors
ClientStorage.notifyConnected() into two functions, testConnection()
and notifyConnected().  testConnection creates the RPC stub and calls
the register() method; it returns the stub plus a flag indicating
whether this connection was preferred or sub-optimal.  If the
register() method raises ReadOnlyError, and the new option
read_only_fallback was true on the ClientStorage constructor, it is
retried with its read_only argument set to 1, and the stub is returned
with the sub-optimal flag.  notifyConnected() now receives the stub
returned by testConnection(), and starts the verification as before.

XXX The read_only_fallback  feature is not yet tested.

XXX More work is needed; when a suboptimal connection is used, the
ConnectThread must stay around trying to get a preferred connection,
and then it must switch connections on the ClientStorage (how???).

different classes that both define a register() method, with different
signatures.  Rename StorageServer.register() to
register_connection().  Also rename its newConnection() method to
new_connection(), for naming consistency.

more understandable.

Got rid of the Connected() exception -- connect(), now renamed to
try_connect(), returns a 1/0 result instead of raising Connected() to
indicate success.

table.
