Re: Playing music using pike and SDL.
by Martin Nilsson (lvl 60) ＠ Pike (-) developers forum 13 Mar '26

Were you not able to get any C code to play through SDL either? Does your SDL library have a mixer compiled in it (I think it is optional)?

managing comport settings in linux
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 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.

Pike Meet-up 2018-Q1
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 20 Oct '21

Hi. At Pike Conference 2017 it was decided that we ought to hold a more informal meeting in Linköping ~ once every quarter. As the three month mark from the conference is coming up soon, it seems time to announce the first such meeting for 2018: Pike Meet-up 2018-Q1 Date: 2018-02-03 (Sat) Time: 10:00 - afternoon/evening Place: Roxen IS AB S:t Larsgatan 22A Linköping Welcome! /grubba

8.0 test suite failures: fork() + time on macOS 10.12+

SSL hang during handshake
by H William Welliver 25 Nov '20

25 Nov '20

Hi all- I’ve been doing some experiments with SNI and have noticed a potential problem: If SSL.Context->find_cert_domain() doesn’t return a matching certificate, the server handshake doesn’t complete. This causes the client to hang indefinitely. SSL.Context->add_cert() supports (but does not require) a fallback certificate to be specified. Because the server does not control the value it receives, an improperly configured SSL Context could cause a denial of service. I propose to change SSL.ServerConnection so that an alert message is sent if a certificate cannot be chosen. Does that seem like a reasonable approach? If I don’t hear any objections in the next day or so, I’ll add this to master and 8.0 (where the problem definitely exists). Bill

8.0 fixes for macOS/illumos
by H William Welliver 25 Nov '20

25 Nov '20

I think I’ve fixed the hang after fork() problem I reported earlier by having the mach clock service reinitialized after fork(). I also discovered that fs_event callbacks weren’t working on kqueue() based backends. I think I’ve fixed this as well, however while the _Stdio testsuite passes on its own, the kqueue tests fail when run in the scope of a full make verify. I’m not sure what to make of that, but I think it’s an edge case. I don’t think it’s related to fork()ing, as the poll device gets reopened after fork. If all goes well with pike farm, I’ll cherry pick these changes to master. I also back ported the fix for CritBit grubba mentioned a few days ago, and that seems to have fixed the problem on Solaris/illumos with old gmp. Bill

8.0 test suite failures: Critbit on illumos
by H William Welliver 21 Nov '20

21 Nov '20

I’m running builds of 8.0 to make sure we don’t have any major test failures, and I’ve run into a few problems so far. I’ll put them in separate emails so they are more manageable. If anyone can offer any assistance, that would be most appreciated. I can supply any info needed, up to getting you a logon to the systems in question. Next up are a series of Critbit failures on a current version of illumos: uname -a SunOS centaur 5.11 joyent_20201023T231824Z i86pc i386 i86pc Solaris ...

Pikefarm client

Hello, What is the correct client for participating to the pikefarm ? The one listed on the website [1] seems outdated. I guess I should start with the one on GitHub ? [2] Thank you, [1] https://pike.lysator.liu.se/development/pikefarm/ <https://pike.lysator.liu.se/development/pikefarm/> [2] https://github.com/pikelang/xenofarm <https://github.com/pikelang/xenofarm> — Bertrand
