Pike conference
by Bill Welliver 19 Aug '03

19 Aug '03

I've updated the list to include Bertrand's comments. Please note that I have no official affiliation with this conference; I'm just trying to keep things rolling [at least as far as the caudium stuff is concerned], so if I'm stepping on someone's feet, please let me know :) Here's a list of the topics thrown out on the caudium devel list. Are there any others that I missed? (they get more directly pike related as you go down the list) My thinking [and previous experience] is that we should think about whether we will discuss all of these topics, how much time we should devote to them, and see if someone wants to take a lead on that (sort of a session chair and/or discussion facilitator). They'd be responsible for having any supporting material (slides, handouts, presentations, etc) and for making sure that any discussions/outcomes were preserved for use later. Obviously, a session chair could delegate some of the responsibility to others. Once you had an idea of what we were going to do and who would coordinate the various pieces, you could get a schedule together. Another thing to consider is if there will be enough people of different interestes to consider splitting up the group and having 2 or more concurrent sessions going at once. I'm not sure whether that's feasible or desireable, but figured I'd mention it anyhow. I guess we probably need to know who is in overall command of the conference. Martin, do you know who's running the show? Is anyone from Paderborn listening? :) Any thoughts?

Sorry, minor typo there. MODDIR must end with a slash, so it should be set to Tools.pmod/Standalone.pmod/ in the example.

valgrind-20030725

The valgrind home page claim that their latest valgrind, valgrind-20030725 is better than anything seen so far. Unfortunately it doesn't work with Pike in a strange way...

Machine code efficiency
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 08 Aug '03

08 Aug '03

I've tested on a few more architectures now and it seems that it indeed is Athlon specific. The following are measurements with machine code. The last column is the difference in user time wrt without machine code. sparc (Ultra-80): test total user mem (runs) diff Compile.................... 6.588s 4.096s -1kb (76) (5894 lines/s) 2% Compile & Exec............. 7.060s 4.488s -1kb (71) (134009 lines/s) 0% Ackermann.................. 5.311s 2.841s -1kb (95) -10% Loops Nested (local)....... 4.426s 1.981s -1kb (100) (8469060 iters/s) 9% Loops Nested (global)...... 4.992s 2.532s -1kb (100) (6625550 iters/s) -18% Loops Recursed............. 4.747s 2.270s -1kb (100) (461968 iters/s) -16% Seems like local variable accesses could be improved on sparc. ia32 (PIII 700 MHz): test total user mem (runs) diff Compile.................... 3.462s 2.945s 5260kb (100) (8198 lines/s) 11% Compile & Exec............. 3.408s 2.760s 3628kb (100) (217922 lines/s) 9% Ackermann.................. 1.789s 1.323s 3716kb (100) -8% Loops Nested (local)....... 1.217s 0.740s 3504kb (100) (22678034 iters/s) -27% Loops Nested (global)...... 1.857s 1.359s 3504kb (100) (12342540 iters/s) -23% Loops Recursed............. 1.512s 1.031s 3504kb (100) (1017443 iters/s) -9% ia32 (Athlon XP 1535 MHz): test total user mem (runs) diff Compile.................... 1.464s 1.251s 5244kb (100) (19300 lines/s) 7% Compile & Exec............. 1.389s 1.197s 3656kb (100) (502423 lines/s) 6% Ackermann.................. 1.387s 1.198s 3724kb (100) 84% !! Loops Nested (local)....... 0.450s 0.261s 3508kb (100) (64182112 iters/s) -39% Loops Nested (global)...... 0.787s 0.598s 3508kb (100) (28036812 iters/s) -23% Loops Recursed............. 1.518s 1.329s 3508kb (100) (789115 iters/s) 172% !! I also tried with a binary copied from the PIII system on my Athlon in case there's some kind of compiler difference, but that didn't change anything much. It's amazing that some cpu difference can have this dramatic effect on function call performance. It'd be interesting to see this on more systems. / Martin Stjernholm, Roxen IS Previous text: >2003-07-31 02:18: >Subject: Machine code efficiency >-------------------------------------------------------------------- >It's on an Athlon XP.

Perhaps I should point out that the percentages in the "diff" columns are still against non-machine code and not the previous machine code results.

LDAP decoding problem
by Peter Bortas (med ny klient) ＠ Pike (-) developers forum 07 Aug '03

07 Aug '03

Using Pike 7.2.259 delivered with Roxen 2.2.252 I tried to extract a huge amount uf user data via LDAP search. This ended badly: > object s = c->search("(objectclass=liustudent)", 0 ,({ "cn", "uid", "dn" })); utf8_to_string(): Unexpected continuation block 0xb4 at index 7. /export/home/zino/roxen/roxen/server-2.2.252/pike/lib/pike/modules/Protocols.pmod/LDAP.pmod/client.pike:137: _get_attr_values(3,Types.asn1_sequence()) /export/home/zino/roxen/roxen/server-2.2.252/pike/lib/pike/modules/Protocols.pmod/LDAP.pmod/client.pike:154: _New_decode(({"*censored*",,,4447 0})) /export/home/zino/roxen/roxen/server-2.2.252/pike/lib/pike/modules/Protocols.pmod/LDAP.pmod/client.pike:194: create(({"*censored*",,,44471}),0 ) /export/home/zino/roxen/roxen/server-2.2.252/pike/lib/pike/modules/Protocols.pmod/LDAP.pmod/client.pike: Stdio.File("socket", "*censored*:389", 777 /* fd=7 */)->result() /export/home/zino/roxen/roxen/server-2.2.252/pike/lib/pike/modules/Protocols.pmod/LDAP.pmod/client.pike:937: Stdio.File("socket", "*censored*:389", 777 /* fd=7 */)->search("( objectclass=liustudent)",0,({"cn","uid","dn"})) -:1: ___Foo4711() We are talking more than 40k users, so "out of memory" (or death by signal) I could have expected, but not this. What goes wrong really? Sidenote: A streaming search would probably be good if someone has time they don't know what to do with. This particular search takes more than one hour to execute. (I can solve my problem in other ways, but connection->search()->next()->fetch()->next()->fetch() and so on seemed natural when I'm going to check every user.)
