Fixed a bug with using ABC files and primorials as primeserver didn't re-initialize after processing the first line.
Fixed a bug with the p() and nextprime() functions when used in scripts.

I strongly recommend that you get 3.5.1 (which is still a beta BTW) in case you are trying to use 3.5.0.

Right now only the Windows build is available. I hope to get the Mac and Linux ones up later today.

I get a crash in 3.5.1, apparently when I use the p(n) function (from the command line, GUI, or from an ABC2 file). E.g. this makes it crash: "pfgw32 -q349*p(1)^5-1".

This is already fixed. 3.5.2 will be posted tomorrow.

I have posted 3.5.2 patching the known issues.

A small bug was discovered in the nextprime function. I have re-released 3.5.2 to fix it. No other changes were made.

Oh, @#$!

I've used 3.5.0 with scr.txt to start a couple bases (R291, S381). They were royally screwed. A huge bunch of small composites (e.g. 2*291^1-1) "pass" both PRP and the N+1 test and get into pl_prime.txt.

Was this fixed in 3.5.2? I am switching back to 3.4.9, better safe than sorry. (of course, many of the k values that passed "as primes at n=1 with 3.5.0" get other small primes, but a significant portion don't; the whole script has to be rerun.)

I've posted 3.5.5. Testing has shown that known problems are resolved. Batalov, can you do a little test to see if it works correctly for those two bases?

Batalov · 2011-10-08, 19:54

Will do.

Batalov · 2011-10-08, 21:00

Looks good now.

I tested on R291, S381 (so PRP and both N+1 and N-1 on small inputs were in use) - on linux64 and on Windows (both GUI and plain). The outputs were correct.

Rogue,
There appears to be a bug in the command line option -f,
choose any value other than 100 and the software defaults to trial factoring to 4000000000 (tried 125, 110,95).
Using PFGW 3.5.5 win32 GUI
Command line: -f100 -tp in.txt
(wanted to use -f125)
Noticed when testing 19081#*2^19081-1

Thanks for the bug report. I'll look into it.
