managing comport settings in linux
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 13 Mar '26

13 Mar '26

Not a good idea; the design philosophy of Pike is that Pike-level code should never be able to cause memory corruption at C-level. With ioctls there's no way to know what data a specific ioctl wants without reading the documentation for that specific ioctl for that specific OS. ioctls and fcntls are a way for device handlers to hook in APIs that aren't standard across all filedescriptors. / Henrik Grubbström (Lysator) Previous text: >2004-08-17 13:32: >Subject: managing comport settings in linux >-------------------------------------------------------------------- >What would be nice, is a way to define ioctl methods in >Pike.

hi, can you explain why: random(allocate(3,9)[*]); or random(({9,9,9})[*]); don't work, while array foo = allocate(3,9); random(foo[*]); does? greetings, martin.

Pike string hashing
by Marcus Agehall (PacketFront) ＠ Pike (-) developers forum 20 Apr '05

20 Apr '05

I'm a bit curious about the string hashing algorithm used in Pike. What algorithm is it based on and what complexities does it exhibit? Was it selected at random or is there some rationale behind it..?

MySQL big_query in 7.7
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 10 Apr '05

10 Apr '05

I think the new streaming behavior in Sql.mysql.big_query is nice and as it should be, but it's causing too much headaches in existing applications - the old de-facto behavior is too ingrained. So a proposal is to instead do like this: query: Like today - slow and memory consuming. big_query: A variant of query() that still is nonstreaming. I.e. it only avoids the very bulky response format of query(). streaming_query: Like big_query but guaranteed to stream if it exists. It's database dependent whether other queries can be issued while a streaming_query response object exists. It's of course also database dependent if there are locks on the tables in the server while the response object exists. While at it, we could also consider generalizing the big_typed_query interface that the oracle module provides: big_typed_query: Like big_query but doesn't convert everything to strings. Integers and floats are kept that way, Date/timestamps are Calendar objects, there are objects for representing the NULL value for each type. streaming_typed_query: Streaming variant of big_typed_query.

xenofarm, 1 down 1 to go.
by Marc Dirix 16 Mar '05

16 Mar '05

As stated xenofarm reports 2 errors. IMO this one is a bit harder. Pike version=7.7.13 The problem fails in running test_resolve.pike. Pike segfaults. After logging I found the program to fail with one file. If I remove the file with which this occurs (FIPS10_4.pmod) it doesn't segfault anymore. When using hilfe, the same error occurs: > master()->resolv(Standards.FIPS10_4.pmod); Segmentation fault This *only* occurs on my sparc64 (debian) and not on a i386. I've created an test-program which inherits Standards.FIPS10_4 it also segfaults. I've attached an strace on this process which I've included as attachment (hope it helps). I can send more debugging info if necessary, but I have no clue where to go next. Best regards, Marc

Re: xenofarm & Calendar
by Mirar ＠ Pike developers forum 26 Feb '05

The string is which timezone in Calendar.Timezone will be used, or a string to identify the "tzdata" timezone (Europe/Stockholm-like). The "locale" timezone is a magic timezone that will, from the TZ string and/or localtime() function, determine which timezone the locale settings are put to. If it fails, it will default to Timezone.localtime(), which uses localtime() for time offset and names. Like this: | > Calendar.Timezone["locale"]; | (2) Result: Rule.Timezone(Europe/Stockholm) ... | orchid% TZ=UTC pike | Pike v7.7 release 11 running Hilfe v3.5 (Incremental Pike Frontend) | > Calendar.Timezone["locale"]; | (1) Result: Timezone(UTC) >Changing [pike]/lib/modules/Calendar.pmod/localization.h helps, but >how is this done for every recompile of xenofarm? It isn't. It's just for your install. So this isn't a fix to the original problem with xenofarm.
