Hi John -
Yes, the commit you point to ("Big web framework refactoring" of 2008)
seems to be the the historical moment when the callbacks vocab was
moved from extra/furnace/callbacks/ to unmaintained/:
*13 * extra/furnace/callbacks/callbacks.factor →
unmaintained/cont-responder/callbacks.factor
But I'm trying to understand just why the callback code was sidelined.
Note that I'm running OS X 10.6.8, & thus grabbed the 7 February build with:
git clone https://github.com/slavapestov/factor.git && cd factor &&
./build-support/factor.sh update
So I have the unmaintained directory in my Factor. The source for callbacks
is now there, in unmaintained/cont-responder/, although the preamble of
callbacks.factor
still places it IN: furnace.callbacks.
Question is, did the callbacks code break in the framework refactoring, or
is it deprecated
for security reasons (ergo the the admonition "Factor source files should
not be executable")?
Or should callbacks not be used in responders for some other reason, e.g.,
"callcc1 in responders
considered harmful"? Or does the callbacks vocab just need more work to
integrate it back
into the updated Furnace framework?
I do find a reference to a Factor cont-responder using callcc0/1 in a 2004
post by Chris Double <http://double.co.nz/factor/cont-responder.factor>.
Is there some connection with this old work and the current state of the
Furnace framework?
Interesting. Puzzling! Any insights welcome.
Thanks,
~cw
