multiset fix backported
by Peter Bortas ＠ Pike developers forum 07 Apr '09

07 Apr '09

I just backported the multiset fix to 7.6 since we are getting it by it on a regular basis. The test suite runs fine even with TEST_MULTISET, but someone more familiar with the code should probably have a look to make sure I didn't mess something up.

(semi-)multicore support?
by Arjan van Staalduijnen 02 Apr '09

02 Apr '09

Hi, Unfortunately we all still have to do without multicore or multi-cpu support in pike. Even though I don't know how the stuff works at the lowest levels I am aware it has something to do with the way pike handles it's variable structures internally, and it is definitely not a simple thing to change while maintaining a good performance at it. My curiousity is about something different, but related to having some limited multicore support. I vaguely remember hearing, or having read something somewhere about the way pike interacts with libmysql. My memory might be fooled by wishful thinking, so I might be completely wrong. I believe I understood pike is able to release some restrictions at the moment it knows it enters the code for libmysql. This would be the case because it would be benificial for performance; the mysql library would be able to switch to a mode where it could manage it's memory more freely, or where it would be able to run on a different core/cpu. If that is possible, I wonder if libmysql is the only C-library doing this kind of trick, or if other libraries (especially the CPU and memory intensive ones) are doing this kind of trick too. Image libraries, zlib and any C-library doing lots of 'library-local' memory operations (libxslt) or any library doing CPU intensive stuff seem really nice candidates... Am I wrong at what I think pike is doing? If not, is this just for libmysql or are other modules doing this too? If I was wrong, is what I was thinking technically possible, or am I just being too idealistic?

Some nitpicking
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 30 Mar '09

30 Mar '09

Commit from Per: Line 3997: */ PIKEFUN float|int(0..0) `()(void|float|int(0..0) sleep_time) { - struct timeval timeout; /* Got bogus gcc warning on timeout.tv_usec. */ + struct timeval timeout; /* Got correct gcc warning on timeout.tv_usec. */ if (sleep_time && sleep_time->type == PIKE_T_FLOAT) { timeout.tv_sec = (long) floor (sleep_time->u.float_number); No, the warning is indeed bogus since the tv_usec field isn't relevant when the tv_sec field is -1. The added assignment is completely unnecessary work.

MHTML

I tried to decode an MHTML file with MIME.Message but got > MIME.Message(Stdio.read_file("v1.mht")); Arrayelement 0 is not a string /home/nilsson/Pike/7.8/lib/modules/MIME.pmod/module.pmod:1183: MIME.Message()->create("Content-Type: multipart/related; start=<op.mhtml.1 238180415787.b2f4904f395b37a5(a)192.168.0.195>; boundary=----------ghanZ9pgi qEYDh7aC9oLbg\r\nContent-Location: http://beta."+[35113],UNDEFINED,UNDEFIN ED,UNDEFINED) /home/nilsson/Pike/7.8/lib/modules/MIME.pmod/module.pmod:0: MIME->Message() HilfeInput:1: HilfeInput()->___HilfeWrapper() This is because the code params[ lower_case(p[0]) ] = p[2..]*""; tries to multiply together an array(string|int). Is the right fix here to sprintf("%c") the integeras and then join the file?

export.pike
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 10 Mar '09

10 Mar '09

// Note: This script is often run with a system pike rather than // the pike being exported. It should therefore attempt // to support older pikes than bleeding edge. Well, fair enough, but do we really need to support older pikes than the current stable? The inclusion of 90 lines of compat code, many of which are never used, doesn't really make the file more pretty...

git down for maintenance

The zone running the git and git-web services on eureka are down until we figure out if git-web needs updating to fix some vulnerabilities.

GIF comments

Hi, Is it possible to add a comment to a GIF file with the Image.GIF library? (using pike 7.4) If this is possible at all, does anyone have some sample code? -- Met vriendelijke groet / With kind regards / mit besten Grüßen, Coen Schalkwijk Software Engineer coen.schalkwijk(a)rtl.nl <mailto:coen.schalkwijk@rtl.nl> coen(a)rtlinteractief.nl <mailto:coen@rtlinteractief.nl> +31 (0)35 671 8915 __________________________________________________________ Deze e-mail en de inhoud is vertrouwelijk en uitsluitend bestemd voor de geadresseerde(n).

resolver problem using .Class
by Arne Goedeke 15 Feb '09

15 Feb '09

I noticed this problem when using pike -M in 7.6 and I guess its known, since it does not occur anymore in pike 7.8. Consider this situation: one has some module directory and a class from that module is used somewhere in module.pmod. Using these examples * dir/module.pmod string h(int i) { return .A()->h(i); } * dir/A.pike string h(int i) { return String.int2char(i); } Now, when using pike -M dir/ I get the following error: dir/A.pike:2:Got placeholder object (resolver problem) when resolving 'String'. dir/A.pike:2:Undefined identifier "String". dir/A.pike:2:Got placeholder object (resolver problem) when resolving 'String'. dir/A.pike:2:Undefined identifier "String". dir/module.pmod:2:Error looking up 'A' in module '.'. Attempt to call the NULL-value Unknown program: 0() The problem goes away either by using A() instead of .A() or by using pike -M dir without the "/". Is this a bug or am I doing something wrong here? arne

replace() with hit information
by Stephen R. van den Berg 14 Feb '09

14 Feb '09

Would replace(string, array(string), array(string), mapping(string:int)) be a useful/convenient interface for the following functionality?: I'd like the 4th argument mapping to be filled by the replace function to tally the number of times it has found and replaced the corresponding string. It is difficult at best to obtain that information (efficiently) otherwise, especially when some of the strings fit in the prefix of some of the others. The actual use case for me is the bindings parser for pgsql, which preferably needs to eliminate any unused variables before constructing the query to be sent to the database. The reason I'm looking at this is because I just had an occurrence of a binding called ":telno" and ":telnopriv", whereas the :telno wasn't present, but the :telnopriv was. Quick checks with has_value() break down in this case, because :telno is found as a prefix of the actually occurring :telnopriv, obviously. Any alternate ideas which solve this problem are welcome, of course. -- Sincerely, Stephen R. van den Berg.
