Thread concurrency question
by Pierre Guillot 13 Jan '18

13 Jan '18

Another problem with the thread but I think I did something wrong. In my plugin, I have one thread that send messages to Pd and processes the DSP chain. I have another thread that manages the GUI. From this thread, I also send messages to Pd but to avoid thread concurrency issues I use "sys_lock" and "sys_unlock". But this seems to produce artifacts (small cracks). When I remove the GUI, there is no more artifacts. And previously when I used a timer (attached to a specific thread) for each GUI object there were a lot of artifacts. So I think the thread context and the artifacts are linked but I can't figure out the real problem. My ideas are a bit going in circle for now so do you think there would be something that I forgot or something goes beyond my knowledge? Should I try to synchronize all the messages on the "main" DSP thread? Cheers, Pierre

Thread concurrency issue
by Pierre Guillot 13 Jan '18

13 Jan '18

I encountered a bad thread concurrency issue using PD in a multi instance/multi thread context. The behavior of the increment and decrement of the static variable *stackcount* is undefined and results mostly in stack overflow. The simplest solution seems to set the variable a TLS with PERTHREAD. Here is a PR that solves the issue: https://github.com/pure-data/pure-data/pull/288. Cheers, Pierre

[pure-data:bugs] #1309 Math links in documentation broken

--- ** [bugs:#1309] Math links in documentation broken** **Status:** open **Group:** v0.48 **Labels:** documentation **Created:** Mon Jan 01, 2018 08:15 PM UTC by Anonymous **Last Updated:** Mon Jan 01, 2018 08:15 PM UTC **Owner:** nobody The "Math" links in the PD manual are broken. For example, on this page: http://write.flossmanuals.net/pure-data/introduction2/ there are two links in the left-hand navigation to "MATH", both of which point to: http://write.flossmanuals.net/pure-data/math/ which says: "I don't know what to do! There is more then one chapter named - "math". I am not sure which one to show." --- Sent from sourceforge.net because pd-dev(a)lists.iem.at is subscribed to https://sourceforge.net/p/pure-data/bugs/ To unsubscribe from further messages, a project admin can change settings at https://sourceforge.net/p/pure-data/admin/bugs/options.
