Careful debugging of the memory leak problem. At this stage,
...
stack frames for interpreted (but not primitive) functions appear not to be being
reclaimed, and the oblist doesn't seem to be being fully reclaimed.

Work on the equality of numbers. The good news: two additional unit tests pass.
...
The bad news: I'm getting segfaults.

Stage one clean up of test files. Some unit tests are still creating temporary files in
...
the project root directory, which is still to be fixed; and *I think* known-failing
tests which I don't intend to fix immediately should be marked in some way.

Fixed the horrendous 'unbound symbol nil' bug. Also work on documentation and

unit tests.

Woohoo! Huge decrease in cells not cleaned up, with fixing one stupid bug.

feature-2: allocating cells with count = 1; 7 unit tests (all bignums) fail.

Work on reducing allocation leaks in read_number(). This is now improved, but not yet satisfactory.

Restandardised formatting.

Generally, changed working with tags as strings to as values.

This seems both cheaper and safer; what's not to like?

Work on exception handling, especially around ratio arithmetic

Much simplified but will break things!

OK, it is BETTER, but not FIXED.
...
(expt 2 63) goes weirdly wrong - returns T.
Internal representation is correct, so fault is in print.

Woohoo! Actual goddamned progress! Multiply might be working!

Print definitely isn't!

A bit of work on time, but it doesn't actually work yet.

Major progress, multiply now almost works
...
There's a premature free() somewhere, and I'm not sure why.
Print depends on divide, which is easy, but also on mod and floor (of rationals) which isn't.
2019-01-21 16:14:25 +00:00

OK, my idea that long multiplication is like long addition is wrong.
...
It's still broken, but it's broken because of fundamental misunderstanding which tinkering won't solve.

Much investigation of bignum problems
...
bignum multiply is still not working, but as bignum read and bignum divide depend on it, it's the problem to hit first.

Bignum issues not yet folly resolved.

OK, adding bignums works; multiplying bignums does not work.
...
There's no evidence of a bug in reading/printing, because the only way I can currently get a number big enough to trigger the supposed bug is by multiplying, which doesn't work.
2019-01-04 11:04:55 +00:00

Now successfully reading/printing 2 cell bignums

Something is wrong with n-cell bignums, but let's make haste slowly.

Now creating the correct internal bignum representation

add_integers returns an integer which by inspection of the internal representation is correct, but the print representation is not correct.

Also printing and reading integers with comma separators.

Begun work on bignums; changed integer size to 64 bits

I'm fairly sure the size of a long int on my machines is 64 bit anyway, but for portability it needs to be explicit.
