The source code history of Thread is kept by a distributed version control system called Fossil. The master copy of Thread sources are kept here at
and a mirror server is kept at
in case anything goes wrong with the master.
Tracking or contributing to the Thread sources requires a release of Fossil that supports the
fossil open --nested
to determine the vintage of your fossil client program, and confirm that it is no older than 2011-02-08. Upgrade as necessary.
Then start by cloning the repositories for Thread and tclconfig, a set of TEA build support files that Thread makes use of.
fossil clone http://core.tcl.tk/thread/ /path/to/thread.fossil
fossil clone http://core.tcl.tk/tclconfig/ /path/to/tclconfig.fossil
Then construct your workspace:
fossil open /path/to/thread.fossil trunk
fossil open --nested /path/to/tclconfig.fossil trunk
And at that point you have in /my/work/space/thread the current development state of the source files of Thread and tclconfig, which you can build, install, edit, etc.
