- 20:12 Design #1630 (New): Signal handler not portable?
- Bruns reported by email that CoCoALib does not compile on an @"msys"@ platform because @sigaction@ is absent.
Inve... - 20:10 Feature #1488 (Feedback): BuiltIn Interreduce-Function
- Is there documentation now?
- 20:08 Design #1617: UnivariateIndetIndex: exact semantics
- I have updated the documentation to the current behaviour.

- 16:09 Feature #1103: Pseudo-zero-dim ideals
- see also #1254
- 16:07 Feature #1103: Pseudo-zero-dim ideals
- There is something very similar for RationalSolve in CoCoA-5.
Anna: consider that design and copy:... - 16:05 Feature #1254: New function: MinPoly for pseudo-zero-dimensional ideals
- Anna will try do this; perhaps this is a helpful prototype for issue #1103.
A very simple approach here would be t... - 15:54 Design #1628: Unused variables, params, data members
- I tried changing @CoCoA_ASSERT@ so that it expanded to @(void)sizeof(cond)@, *BUT* this worked badly because some ass...
- 15:42 Feature #1235 (In Progress): FreeModule: get canonical basis
- Agreed: the proposal in comment 5 is accepted.
To clarify the order of the elements in the canonical basis should ... - 15:36 Support #1612: Merge the doc file RadicalMembership.txt into ideal.txt
- Anna will do this!
Soon... I hope! - 15:34 Bug #536 (In Progress): Make RingBase::myCharacteristic a fn rather than a proc
- Anna approves too.
Suggestion: create also a fn which returns a machine @long@ (if poss, o/w error).

- 20:56 Support #1265: Unregistered TXT files in doc
- I have added a "first" version of doc for @IdealOfPoints@ and @IdealOfProjectivePoints@.
- 19:57 Support #1265: Unregistered TXT files in doc
- The doc for @assert@ had already been added. I have revised the source code in @assert.H@ slightly.
- 19:20 Support #1265: Unregistered TXT files in doc
- I have just added doc for *@exception@* to the indexes.
- 20:07 Design #1422: Remove flag IhaveGBasisValue?
- We should see who uses the flag @IHaveGBasis@.
Presumably it could be replaced by a function which returns true if t... - 19:05 Feature #1235: FreeModule: get canonical basis
- If we want a special fn for getting the standard/canonical basis for a free module then it could be called *@Canonica...
- 18:58 Support #1591 (In Progress): Compilation of Normaliz
- What is the status of this issue?
Have it been resolved? Is there documentation? It would be good to close it, if ... - 18:55 Design #1628: Unused variables, params, data members
- I have just implemented the KISS approach: namely 2 @#ifdef@ blocks. Everything compiles, & all tests pass (both wit...
- 18:03 Design #1628: Unused variables, params, data members
- The KISS solution would be to use the @CoCoA_DEBUG@ macro.
I'm not keen to use macros (esp. to make @#ifdef@ blocks ... - 18:01 Design #1628 (In Progress): Unused variables, params, data members
- @clang@ is probably correct to report that the data-members are unused.
Their presence makes objects of this class n... - 17:59 Design #1628 (In Progress): Unused variables, params, data members
- Anna reports that clang issues warning about unused data-members (in @MatrixFpNonRed@).
The data-members are used wh... - 17:01 Design #1528 (In Progress): MacOS compilation with clang
- We have made some inprovements.
Clang's errors/warnings are often quite helpful (but sometimes also annoying).
- 16:48 Support #1618 (In Progress): Tidy ex-RingElem2
- I have tried to improve the structure of the code. What is printed out is tedious to follow -- can we make that prin...

- Here is a way of making test cases for computing determinant:
take a unimodular matrix, and multiply it by a nzzd (w... - 19:47 Design #1625 (Resolved): Use new C++ keyword override
- I have checked in (and found several errors/inconsistencies while doing so).
All compiles and works fine on my Linux... - 19:46 Design #1627 (Resolved): Use keyword "delete" for deleted functions
- I have checked in my changes. All compiles fine on my Linux box.

- 21:51 Design #1627: Use keyword "delete" for deleted functions
- I have done the first wave (too much train travel).
Very mind-numbing doing these almost mechanical changes.
My cop... - 21:49 Design #1627 (Closed): Use keyword "delete" for deleted functions

- 19:09 Bug #536: Make RingBase::myCharacteristic a fn rather than a proc
- Now we have moved to C++14, and @BigInt@ has a move ctor, we can implement this change.
Should there be a speed ch... - 09:38 Design #1625: Use new C++ keyword override

- 08:22 Feature #1589 (Feedback): IdealOfPoints: allow matrix of points to be defined over "wrong" ring
- Added test

- 22:09 Design #1608 (Closed): Domain of definition of NextPrime (and PrevPrime)
- 21:48 Design #1617 (Resolved): UnivariateIndetIndex: exact semantics
- I have checked in the version which rejects constant but accepts polyrings with 1 indet.
- 20:40 Design #1617: UnivariateIndetIndex: exact semantics
- I tried throwing an exception if the arg was a constant or if the polyring had just 1 indet, but several tests failed...
- 15:52 Design #1617: UnivariateIndetIndex: exact semantics
- If we do change the semantics, *don't forget to change the doc as well!* And perhaps also change the tests!
- 15:51 Design #1617 (In Progress): UnivariateIndetIndex: exact semantics
- I have just modified the imple of @UnivariateIndetIndex@ so that it produces an error if the input is constant or if ...
- 15:56 Design #950: factor and SmoothFactor for integers --> FactorINT, FactorINT_TrialDiv, FactorINT_PollardRho
- Robbiano would like @factor@ to work for integers (or some integers, at least).
How can we do this reasonably? Mayb...

- 14:24 Bug #1620 (New): MinPolyQuot not documented
- MinPolyQuot is available in CoCoALib but is not documented.
- 14:22 Feature #1619 (Closed): Make saturate available in CoCoALib
- It seems like this is already implemented. There is a function mySaturate in _AlgebraicCore/SparsePolyOps-ideal.C_.

- 15:50 Design #1617: UnivariateIndetIndex: exact semantics
- Mmm, should it be an error to call @UnivariateIndetIndex@ if the polyring has just 1 indet?
After all, the answer i... - 15:48 Support #1618 (Closed): Tidy ex-RingElem2
- I think that *@ex-RingElem2@* needs to be updated/tidied.
For instance, there is no need to pass the ring to the f...
13 Oct 2021
- 20:34 Design #1617: UnivariateIndetIndex: exact semantics
- What about the case of a constant poly in a polyring with just 1 indet?
Error or not? (assuming we opt for an error... - 20:14 Design #1617 (Closed): UnivariateIndetIndex: exact semantics

In particular what should the function return if passed ...
