/* The threading situation is complicated. Tcl is not thread-safe, except
when configured with --enable-threads.
2012-10-16 16:50:34 -03:00
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
2012-10-16 16:50:34 -03:00
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.
If Tcl is threaded, this approach won't work anymore. The Tcl
interpreter is only valid in the thread that created it, and all Tk
activity must happen in this thread, also. That means that the
mainloop must be invoked in the thread that created the
interpreter. Invoking commands from other threads is possible;
_tkinter will queue an event for the interpreter thread, which will
then execute the command and pass back the result. If the main
thread is not in the mainloop, and invoking commands causes an
exception; if the main loop is running but not processing events,
the command invocation will block.
In addition, for a threaded Tcl, a single global tcl_tstate won't
be sufficient anymore, since multiple Tcl interpreters may
simultaneously dispatch in different threads. So we use the Tcl TLS
API.

/* This is the main entry point for calling a Tcl command.
It supports three cases, with regard to threading:
1. Tcl is not threaded: Must have the Tcl lock, then can invoke command in
the context of the calling thread.
2. Tcl is threaded, caller of the command is in the interpreter thread:
Execute the command in the calling thread. Since the Tcl lock will
not be used, we can merge that with case 1.
3. Tcl is threaded, caller is in a different thread: Must queue an event to
the interpreter thread. Allocation of Tcl objects needs to occur in the
interpreter thread, so we ship the PyObject* args to the target thread,
and perform processing there. */

This was using 4 bytes for each such piece of info regardless of platform. This didn't really matter before (proof: no bug reports, and the debug-build obmalloc would have assert-failed if it was ever asked for a chunk of memory >= 2**32 bytes), since container indices were plain ints. But after the Py_ssize_t changes, it's at least theoretically possible to allocate a list or string whose guts exceed 2**32 bytes, and the PYMALLOC_DEBUG routines would fail then (having only 4 bytes to record the originally requested size). Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG build's extra debugging fields.

This was using 4 bytes for each such piece of info regardless of platform. This didn't really matter before (proof: no bug reports, and the debug-build obmalloc would have assert-failed if it was ever asked for a chunk of memory >= 2**32 bytes), since container indices were plain ints. But after the Py_ssize_t changes, it's at least theoretically possible to allocate a list or string whose guts exceed 2**32 bytes, and the PYMALLOC_DEBUG routines would fail then (having only 4 bytes to record the originally requested size). Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG build's extra debugging fields. This won't make any difference on 32-bit boxes, but will add 16 bytes to each allocation in a debug build on a 64-bit box. ........ r46638 | tim.peters | 2006-06-04 05:38:04 +0200 (Sun, 04 Jun 2006) | 4 lines _PyObject_DebugMalloc(): The return value should add 2*sizeof(size_t) now, not 8.
