16:05 CoCoA-5 Feature #25: Function "Call": Based on the premise "It is easier to add features later than to remove them", JAA suggests that we do not offer a @C... John Abbott
15:58 CoCoA-5 Slug #96: sort is too slow: It seems highly likely that copies are being made of the list being sorted. Here is my justification:
I created a... John Abbott
12:26 CoCoA-5 Slug #96 (New): sort is too slow: Sorting is achieved by $list.QuickSort.
Unfortunately it should be called SlowSort. Complexity seems to be quadra... John Abbott

12:38 CoCoA-5 Feature #95 (New): Error/warning if fn-proc is neither fn nor proc?: My email records show that we wrote about this on 2010-05-19.
C5 distinguishes fns from procs simply by the nature... John Abbott
12:08 CoCoA-5 Bug #94 (Closed): Default reason for protected variables: Attempting to set a variable which has been @protect@-ed without an explicit reason produces an unsatisfactory error ... John Abbott

17:14 CoCoA-5 Feature #93 (Closed): Hilbert series: global output rings for non-standard gradings: Hilbert series for rings with standard gradings are all in a single QQ[t].
All other case create a ring for every ... Anna Maria Bigatti

16:13 CoCoALib Feature #92 (In Progress): Error Codes: BadIndex: We've been talking a lot about how to classify errors and how many errors (error classes) we should have.
[see relat... Anna Maria Bigatti

14:04 CoCoALib Feature #91 (Closed): Return type & name for "indets" of a PP: JAA has recently added the fn @indets@ to be applied to a PP.
Its return type is @vector<long>@ being a list (ordere... John Abbott
13:25 CoCoA-5 Feature #90 (Closed): Make the new fn CoefficientsWRT available in C5: JAA has recently added CoefficientsWRT, ContentWRT, and a few other fns to CoCoALib.
Make these fns available to C5 ... John Abbott

18:41 CoCoALib Feature #28 (Closed): rename RingQ, RingZ --> RingQQ, RingZZ: Anna Maria Bigatti

22:51 CoCoALib Bug #89 (Closed): MachineInt or long as fn arg type for indices: In file @PPMonoid.H@ several functions expect a @long@ arg to indicate the index of an indet.
Should these arg typ... John Abbott
22:46 Bug #55: MSVC10 - static member fields: I looked on internet, but did not find an answer which I feel is truly definitive. If the initializer is a constant ... John Abbott
17:02 Bug #55: MSVC10 - static member fields: It doesn't seem a problem in VC10 SP1 (tried on a toy example).
From my understanding of the standard, it shouldn't ... Giovanni Lagorio
16:56 CoCoA-5 Slug #31: theValue makes copy: The solution is to implement a move constructor in BigInt (and every "huge" data structure ;-) ) Giovanni Lagorio

16:29 CoCoALib Support #87: Cleanup header for ring classes (so that they are e-diff-able): 1 - separate more clearly member functions "of the same type".
2 - emphasize what is inherited from what.
3 - remov... Anna Maria Bigatti
16:09 CoCoALib Support #87 (New): Cleanup header for ring classes (so that they are e-diff-able): Anna Maria Bigatti
16:12 CoCoA-5 Bug #88 (Closed): Makefile problem with GUI on linux: it doesn't seem to generate the .pro files....
I'd have sworn it used to work....

15:19 CoCoALib Support #86 (Closed): Clean up DivMask and doc: DivMask contain old style doxygen documentation.
Clean it up. Anna Maria Bigatti

15:18 CoCoALib Design #64: submat takes only vector<long>: For functions which take single machine integer values as arguments, the coding guidelines say to use @MachineInt@ wh... John Abbott
15:10 CoCoALib Bug #6: Sort out RingElem, RefRingElem, ConstRefRingElem mess: JAA has undone the changes he made while trying & failing to improve the current impl of @RingElem@ and friends. Luc... John Abbott

16:52 CoCoALib Feature #84: Names for random streams: *Anna:* remove RandomLong(RndSrc)
OK, at least until someone says they really need it.
*Added 2012-12-04:* JAA conf... John Abbott
11:24 CoCoALib Feature #84: Names for random streams: *Anna:* I have implemented @RandomLong(lwb, upb)@ and it works fine. I think it is the nicest interface.
Good idea!!
