sscanf and Gmp.mpq
by Johan Sundstr�m (Achtung Liebe!) ＠ Pike (-) developers forum 07 Feb '04

07 Feb '04

Would a sscanf format %q for turning numbers (possibly with decimals) to Gmp.mpq objects be a good, bad, easy and/or hard addition to make? (I was just considering looking at it when I wake up later on today.)

sscanf and Gmp.mpq
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 07 Feb '04

In fact, the object could be given by the lvalue: Gmp.mpq q = Gmp.mpq(); sscanf("17", "%¤f", q); That won't work for array_sscanf() though.

Should the end of the ranges array really look like {0x01d1aa,0x01d1ad}, {0x0e0100-0x10fffd} }; ? (I don't know what this is used for).

Nettle 1.7 and pike 7.5
by Xavier Beaudouin 06 Feb '04

06 Feb '04

Hello there, Seems that Pike 7.5 is not compatible with nettle 1.7... because it look for nettle_md5_init() and since it doesn't exist on Nettle 1.7.... It fails... Ok, now this is bad that 1.8 has some api changes.... and/or that Pike 7.5 cannot cope with Nettle 1.7 ;( My question is why do pike doen't support both api ??? /Xavier

I get lots of errors like Compiling /home/nisse/hack/pike/src/pike_search.c In file included from /home/nisse/hack/pike/src/stralloc.h:12, from /home/nisse/hack/pike/src/pike_memory.h:12, from /home/nisse/hack/pike/src/pike_search.c:15: /home/nisse/hack/pike/src/block_alloc_h.h:20:2: #error "block_alloc.h must be included after all uses of block_alloc_h.h" What's this about?

I think it may be possible to do the sha1 compression function all in x86 registers. Five registers for the state, one for pointing to the input, and then one free temporary. Benchmark for the C implementation of various hashes: md2 (Update): 2.327MB/s md4 (Update): 171.846MB/s md5 (Update): 114.488MB/s sha1 (Update): 81.916MB/s sha256 (Update): 43.055MB/s / Niels Möller (vässar rödpennan) Previous text: >2004-02-05 17:43: >Subject: Nettle >-------------------------------------------------------------------- >If you are in a good hacking mood, any speedup in SHA1 would be most >welcome.

SSL part two
by Bill Welliver 06 Feb '04

06 Feb '04

I noticed that SSL.handshake supports certificate authentication. That's actually rather nice, however, I've got a problem with the way it's controlled. If the settings are in handshake, there's no way to change them when using sslport, or any other function that uses sslfile directly. Would it make more sense to move those settings to the context object? Would anyone be terribly put out if I did that (or at least added the option)? Any thoughts? Bill

Or at least CPU / Memory / motherboard / OS dependant. If you have two machines with identical configurations, you would most likely get similar values.

Default backend and thread backends?
by Alexander Demenshin 05 Feb '04

05 Feb '04

Hi, Is there any way to _change_ default backend? Something like Pike.DefaultBackend->replace(MyBackend) - so all subsequent calls to call_out() and all file descriptors allocated after this will use new backend? And more... It would be nice to have dedicated backends in some threads, so (say) all calls to call_out() and fd's allocation will use thread-specific backend (if it is set - and default otherwise). Something like Thread.Thread()->set_backend()... All this functionality can be simulated(?) - like intercepting Stdio.File|Stdio.FILE object creation (to use Backend()->add_file()), call_out()s etc., but it wouldn't be as clean as "native" support (there is always chance to overlook something). As to "Why?" - well, I simply don't want to (over)load single backend with callbacks from everywhere... Especially when I've SMP machine - it won't be used efficiently with single backend. Any comments? Regards, /Al

sscanf format parameter for whitespace
by Peter Lundqvist (disjunkt) ＠ Pike (-) developers forum 05 Feb '04

05 Feb '04

Just a thought. It would be darn sexy with a format parameter for whitespaces in sscanf (for whitespace elimination)? array_sscanf(" void foo(10)", "%*w%s%*w%s(%d)" ); array_sscanf(" void foo(10)", "%*[ \t]%s%*[ \t]%s(%d)");
