I think both Jiang, Scott, and I are in agreement that the JAVA_LOCK stuff in the JNI methods do not do anything useful. I think they were originally added before the Notifier class was part of Jacl and Tcl Blend. The Notifier class should be the sole synchronization point for adding an event to the Tcl event queue. The event is then pulled off the queue by the dedicated "event thread" and all command invocations after that are unsynchronized. This is a good thing because you end up with really low synchronization overhead. Currently, both the Tcl Blend and Jacl versions of the notifier seem to be thread safe, so it looks like you can just strip out all of the code that has anything to do with JAVA_LOCK. This JAVA_LOCK thingy is a big global lock that seemed to be needed in the old days of Tcl 8.0, but the 1.3 version of Tcl Blend only supports Tcl 8.3 and Tcl 8.4 so that is no longer a concern. There is also global lock inside unix/unixNotifier.c and win/winNotifier.c that should only be used when Tcl is compiled without thread support. More detailed discussion of these issues can be found in the mailing list archive. The best way to get CVS access on a windows machine is to install Cygwin. You are going to need cygwin to build Tcl Blend on windows anyway, so you should just grab it now. Your best bet is to just get it from a mirror. Download the installer. ftp://ftp.freesoftware.com/pub/sourceware/cygwin/latest/setup.exe Run it and then point it at a mirror like ftp://ftp.freesoftware.com/pub/sourceware/cygwin/latest ftp://ftp.sunsite.utk.edu/pub/cygwin/latest/ Then grab the soure for CVS and run ./configure. It should just configure and compile out of the box. Of course, it might be easier to just use a regular Unix box running samba and just mount that over the network on windows. That is what we do at work. Actually trying to use windows to do any sort of development work is much harder than developing software to run on windows.
