17:34 Design #683: Module index component in internal compressed representation: I shall check in shortly; anyway here is the modified line:... John Abbott
17:10 Design #683: Module index component in internal compressed representation: The definition on line @GBEnv.C:48@ does not work with @SmallExponent_t@ being @unsigned long@. JAA is fixing now.
John Abbott

22:31 Feature #142: Improve threadsafety: I wonder whether the default configuration for CoCoALib should be the threadsafe one (which incurs a run-time efficie... John Abbott

13:14 Bug #746: Problem with GBasis in tower of alg extns: Here is a transcript of what happened...... John Abbott
13:13 Bug #746 (New): Problem with GBasis in tower of alg extns: I tried computing a GBasis in a ring with structure like @QQ(alpha)(beta)[x]@ where @alpha@ and @beta@ are algebraic.... John Abbott
08:39 Feature #728: Noncommutative algebra "of solvable type": No. In my understanding, John correctly described in #2 also Ore algebras (taking into account the note he later adde... Werner M Seiler

07:14 Feature #728: Noncommutative algebra "of solvable type": If I understood well (I asked Viktor Levandovskyy ;-) the definition in #2 is actually of G-Algebras, and Ore-Algebra... Anna Maria Bigatti

18:40 Feature #520 (Closed): Compute inverse in quotient ring (i.e. division in algebraic extn): No problems arisen in the last month (perhaps not much real testing either?)
Anyway, closing.
John Abbott
18:38 Support #739 (Closed): Move code in examples into namespace CoCoA: JAA checked, fixed a few oversights. Otherwise seems fine now. Closing.
John Abbott
18:12 Feature #721 (Closed): CheckForInterrupt: string arg to specify where it was called?: After a brief testing period, the mechanism works (but the C5 interpreter needs to be improved so that a helpful mess... John Abbott
18:04 Feature #689 (Closed): Fault tolerant rational reconstruction: make bad factor publicly accessible: John Abbott

16:20 Feature #743 (In Progress): Better errors: give supplementary info about the error: When CoCoALib produces an error which is then caught by CoCoA-5, the only information from the error which is shown t... John Abbott
15:07 Bug #631 (Closed): Ambiguous: rank for matrix (in ex-matrix1.C): We use the name *@rk@* for the main function, but allow @Rank@ as a component of a compound name (to increase readabi... John Abbott
11:58 Feature #721: CheckForInterrupt: string arg to specify where it was called?: Doesn't seem to be enough to give a suitable error message to cocoa5.
(interrupt code is in @TmpGReductor.C@ and tes... Anna Maria Bigatti
10:55 Support #618: Instructions for compiling libnormaliz: Normaliz is making a new release and we will refine the configuration in September (in Aarhus) Anna Maria Bigatti
10:53 Support #739 (Feedback): Move code in examples into namespace CoCoA: I believe it is all done: there was a problem using @program()@ instead of @CoCoA::program()@ with John compiler, it... Anna Maria Bigatti

17:23 Feature #658 (In Progress): Indets actually in a poly (or vector or matrix): Anna suggests the result could be a @DynamicBitset@; these appear to be like @vector<bool>@ but also support bitwise ... John Abbott
16:44 Feature #91: Return type & name for "indets" of a PP: JAA observes that we already have some vaguely similar functions:
* @radical(PP)@ same as @gcd(PP,product(all_indet... John Abbott
15:42 Slug #742 (In Progress): View PP exponent vector (and order vector?) as an array of long?: On my 32-bit linux virtual machine I observe the following:
* with @int@ and @long@ all loops take about 3.0s (NB @i... John Abbott
15:36 Feature #689 (Feedback): Fault tolerant rational reconstruction: make bad factor publicly accessible: Implemented. Documented. Not really tested :-(
Status --> feedback.
John Abbott
13:02 Slug #679 (Closed): power for PPs is too slow: Apparently everything was already checked in... So I'm considering that ad hoc in-house testing has already happened... John Abbott

20:43 Slug #742: View PP exponent vector (and order vector?) as an array of long?: I get some strange timings on my computer (MacOSX-10.5.8, old compiler).... John Abbott
20:35 Slug #742: View PP exponent vector (and order vector?) as an array of long?: Here is a simplistic test program I have written. It should let you test whether any speed gain is likely if you vie... John Abbott
20:31 Slug #742: View PP exponent vector (and order vector?) as an array of long?: JAA believes that we are already using this trick for order vectors (managed by @OrdvArith@).
Is it worth doing th... John Abbott
20:28 Slug #742 (In Progress): View PP exponent vector (and order vector?) as an array of long?: Current implementations for exponent vectors (in PPMonoid elements) treat them as arrays of @SmallExponent_t@.
It ... John Abbott
19:34 Slug #679: power for PPs is too slow: Apparently I have already done almost everything (but still have to check in).
I was surprised to see that we do not... John Abbott
16:38 Feature #82: C++11 compatibility questions: It seems that a few things noted in issue #83 should actually be in this issue.
Apparently C++11 has a way of find... John Abbott

17:10 Feature #385: Design new errors using inheritance: JAA has now implemented a simple superclass @CoCoA::exception@ from which all exceptions which CocoALib could throw m... John Abbott
17:03 Feature #721 (Feedback): CheckForInterrupt: string arg to specify where it was called?: Code has been updated, tested, documented (with simple example). Checked in.
Changing status to @feedback@.
John Abbott
16:58 Design #641 (Closed): Clean test-FreeModule1: Anna Maria Bigatti
16:15 Bug #705 (Closed): DetDirect calls myAddMul with 0 argument -- funny compilation problem??: No problems encountered after 1 month in feedback. Closing.
John Abbott
16:14 Feature #714 (Closed): Interrupt mechanism: Tested on my computer: pending interrupt and caught interrupt, they both work! Closing Anna Maria Bigatti
14:56 Feature #714 (Feedback): Interrupt mechanism: I've been using the current code for a little while (not really proper testing), and no problems have come up. So ch... John Abbott
