Tcl Source Code

OK, the main point of the sampleextension
is the TEA config/build/install stuff, but
the extension still ought to actually work.
It does not work on 64-bit Linux/Alpha:

My guess is that there's an implicit assumption
of 32-bit "registers".

With the recent changes (TEA 3)
this slightly modified patch seems
to be all we need for 64-bit support.
Thanks, dkf.  tclguy, please test and
apply.

After commenting out the assert(), I get
a [load]-able shared library; thus a valid
pkgIndex.tcl file, and after installing a
`make test` runs successfully with 0 failures.

So, good 64-bit fix (modulo assert-removal),
but new build/install issues discovered.

Problem 1:  The shared library produced with
an --enable-symbols configuration will not
[load].  This means that generation of
pkgIndex.tcl also fails -- silently.  Neither is good.

% load libsample0.4g.so
couldn't load file "libsample0.4g.so":
/local/src/sampleextension/libsample0.4g.so: undefined
symbol: assert

Same problem without --enable-symbols actually:

% load libsample0.4.so
couldn't load file "libsample0.4.so":
/local/src/sampleextension/libsample0.4.so: undefined
symbol: assert

assigning to myself so I'll remember to test this when I get 
home

Could someone try this possible fix?

Well, it's already scared *me* off for a while! ;^)

Perhaps if I was to start by working from the tcllib
version!

that's enough to scare me away.

Ooer!  SHA1Transform (in sample.c) is absolutely not
portable to 64-bit systems (it assumes that
sizeof(long)==4*sizeof(char) and that
sizeof(long[16])==sizeof(char[64]), neither of which is
guaranteed to be true, and both of which could fail
independently.)  Maybe the rest of that file is better, but
I somehow doubt it...

Fixing this bug requires a hefty rewrite of that file, so
I'm dropping the priority.

I'll try to look into this.

I don't have access to a 64 bit system. Sending back to
hobbs in the hope that he can find someone with a 64 bit
system.
