17:40 Bug #226: HilbertBasis segv

Definitely *@valgrind@* time!
I suppose the bug never revealed itself before because @malloc@ may well reserve sli... John Abbott

Still some error (I guess of the same nature): this time triggered by... Anna Maria Bigatti

14:47 Bug #226 (Resolved): HilbertBasis segv

16:28 Bug #226: HilbertBasis segv

I further reduced the error:... Anna Maria Bigatti

16:01 Bug #226 (In Progress): HilbertBasis segv

Here is some "simpler" CoCoA-5 code which triggers the problem:... John Abbott

14:23 Bug #102 (Feedback): Packages: should exported functions be automatically "Protect"ed?

JAA notes that _system protected_ variables cannot be unprotected (_e.g._ the variable *@QQ@*).
Internally the inter... John Abbott

12:11 Support #296: Documentation for Parser/Interpreter

I have already assigned it to myself as I'm the one most using it Anna Maria Bigatti

11:42 Support #296: Documentation for Parser/Interpreter

I thought the most difficult question would be _who is going to do it?_

08:37 Support #296 (In Progress): Documentation for Parser/Interpreter

Even though the code is written quite well it would be handy to have some documentation ;-)
The most difficult quest... Anna Maria Bigatti

08:28 Design #294: BuiltInFunctions: General "OneLiner" for arguments of different type

Not quite the dream solution, but I found this function making life easier:

17:42 Bug #102 (In Progress): Packages: should exported functions be automatically "Protect"ed?

After considering typical use patterns, it makes most sense for *@Export@* to protect the exported names, and for *@D... John Abbott

15:40 Support #293 (Feedback): Add CpuTime to C5 manual

Anna Maria Bigatti

14:50 Bug #226: HilbertBasis segv

If you run the two offending lines in a fresh CoCoA-5 then C5 reports an error that @CurrentRing@ has no value! This... John Abbott

14:43 Bug #100: BringIn should map only the indets in its arg

We need a sort of _partial_ canonical hom which maps symbols which are not in the codomain to zero. Before applying ... John Abbott

12:51 Design #294 (Closed): BuiltInFunctions: General "OneLiner" for arguments of different type

one liner functions work like a dream (thanks Giovanni! ;-)
Is it possible to simplify writing the code for _overloa... Anna Maria Bigatti

12:44 Feature #193: BuiltinFunctions.C getting too long (2000 lines)

Splitting the code seems to work very well.
Now I wonder whether I should also split BuiltinFunctions separating the... Anna Maria Bigatti

18:15 Design #292 (Closed): Rename IndetsCalled to indets

Rename *@IndetsCalled@* to *@indets@*.
Non-trivial because there is already a fn called *@indets@* John Abbott

Giulia has produced a first version of the code for phi: R/I --> S/J.
For next time she will:
