instead. This seems more robust than returning an Unicode string with some unconverted charcters in it. This still doesn't support getting truly binary data out of Tcl, since we look for the trailing null byte; but the old (pre-Unicode) code did this too, so apparently there's no need. (Plus, I really don't feel like finding out how Tcl deals with this in each version.)

/* The threading situation is complicated. Tcl is not thread-safe, except for
|
||
Tcl 8.1, which will probably remain in alpha status for another 6 months
|
||
(and the README says that Tk will probably remain thread-unsafe forever).
|
||
So we need to use a lock around all uses of Tcl. Previously, the Python
|
||
interpreter lock was used for this. However, this causes problems when
|
||
other Python threads need to run while Tcl is blocked waiting for events.
|
||
|
||
To solve this problem, a separate lock for Tcl is introduced. Holding it
|
||
is incompatible with holding Python's interpreter lock. The following four
|
||
macros manipulate both locks together.
|
||
|
||
ENTER_TCL and LEAVE_TCL are brackets, just like Py_BEGIN_ALLOW_THREADS and
|
||
Py_END_ALLOW_THREADS. They should be used whenever a call into Tcl is made
|
||
that could call an event handler, or otherwise affect the state of a Tcl
|
||
interpreter. These assume that the surrounding code has the Python
|
||
interpreter lock; inside the brackets, the Python interpreter lock has been
|
||
released and the lock for Tcl has been acquired.
|
||
|
||
Sometimes, it is necessary to have both the Python lock and the Tcl lock.
|
||
(For example, when transferring data from the Tcl interpreter result to a
|
||
Python string object.) This can be done by using different macros to close
|
||
the ENTER_TCL block: ENTER_OVERLAP reacquires the Python lock (and restores
|
||
the thread state) but doesn't release the Tcl lock; LEAVE_OVERLAP_TCL
|
||
releases the Tcl lock.
|
||
|
||
By contrast, ENTER_PYTHON and LEAVE_PYTHON are used in Tcl event
|
||
handlers when the handler needs to use Python. Such event handlers are
|
||
entered while the lock for Tcl is held; the event handler presumably needs
|
||
to use Python. ENTER_PYTHON releases the lock for Tcl and acquires
|
||
the Python interpreter lock, restoring the appropriate thread state, and
|
||
LEAVE_PYTHON releases the Python interpreter lock and re-acquires the lock
|
||
for Tcl. It is okay for ENTER_TCL/LEAVE_TCL pairs to be contained inside
|
||
the code between ENTER_PYTHON and LEAVE_PYTHON.
|
||
|
||
These locks expand to several statements and brackets; they should not be
|
||
used in branches of if statements and the like.
