Rewriting a unified phasor / metro object for reading tables
by Ed Kelly 07 Mar '14

07 Mar '14

Hi Lists(s), I'm rewriting phasor~ and unifying it with metro so that a pulse is generated from the boundaries of each ramp - so that bars of music can be read using tabread~ objects with a sample-accurate metro. I'm sure someone will say this can already be done, but it has to be dropped into the Ninja Jamm patch, so there isn't really time to rewrite the rest of the patch. I don't fully understand the way phasor~ wraps, but I have the object firing out bar numbers correctly. I'm putting clocks in for 16ths and 24ths of the beat, initiated on each wrap. I need to minimise CPU, so what I want to know is this: Does phasor~ always start from 0 and go to 1, i.e. is there always a signal value of 0 at the start of the ramp and a signal value of 1 at the end? As I write this, my common sense tells me it should be "yes" but I want to make sure. I suppose I should just try it really...

[pure-data:bugs] #1113 Won't Launch without wifi

--- ** [bugs:#1113] Won't Launch without wifi** **Status:** open **Labels:** internet wifi won't launch **Created:** Mon Sep 30, 2013 09:53 PM UTC by Anonymous **Last Updated:** Mon Sep 30, 2013 09:53 PM UTC **Owner:** nobody I just downloaded Pd 0.43.4-extended on my Mac OS X 10.8.5/intel (built-in sound) and I realized that for some reason it will not launch if there is no connection to wifi. As soon as I make a connection, it instantly starts up. If there is no connection, the app will bounce in my dock once or twice and then disappear. Does anyone know why this is happening? --- Sent from sourceforge.net because pd-dev(a)lists.iem.at is subscribed to http://sourceforge.net/p/pure-data/bugs/ To unsubscribe from further messages, a project admin can change settings at http://sourceforge.net/p/pure-data/admin/bugs/options.

[PATCH] Avoid crash in vd~ for nan/inf input values
by Kjetil Matheussen 13 Sep '13

13 Sep '13

As previous discussed in the thread "Whose fault is this crash? (nan and inf)", a patch is pasted below to fix the problem. It might be possible to fix the problem a better way, by checking whether the integer index variable (called "idelsamps") is within bounds, but the complexity of the code goes a little bit above my head. The other two situations mentioned in the thread that might have this problem, namely tabread4~ and poke~, should not have this problem since there are checks that the integer index values are within bounds. diff --git a/pure-data/src/d_array.c b/pure-data/src/d_array.c index d365cf2..9c16a85 100644 --- a/pure-data/src/d_array.c +++ b/pure-data/src/d_array.c @@ -423,7 +423,11 @@ static t_int *tabread4_tilde_perform(t_int *w) for (i = 0; i < n; i++) { - double findex = *in++ + onset; + t_sample inval = *in++; + if(!isfinite(inval)) + inval = 0.0f; + + double findex = inval + onset; int index = findex; t_sample frac, a, b, c, d, cminusb; static int count;

[pure-data:bugs] #1111 bug in mac osx gui with right click menu

--- ** [bugs:#1111] bug in mac osx gui with right click menu** **Status:** open **Labels:** mac oscx **Created:** Thu Sep 12, 2013 03:55 PM UTC by Anonymous **Last Updated:** Thu Sep 12, 2013 03:55 PM UTC **Owner:** nobody Using Pd-extended 32 bits version 0.43.4 on mac osx 10.6.8. When i right click in a patcher, on an object or wherever in Pd, the contextual menu with "Help Open Properties" appears, but sometimes it is stuck : i can't left click somewhere else to make it disappear, i can't click anywhere else in PureData, hovering on items of the menu doens't highlight them in blue... this problem is inconsistent : sometimes it works without problem, someitmes it doesn't, at worse i have to wait abit and try to left/right click in rage everywhere for the menu eventually to disappear or for beeing able to select one item of said menu (phew !). At first it seemed like a minor problem, but the more you stay in pure data, the more it becomes a real deal, because it becomes problematic to open the properties for an object and it prevents working efficiently. --- Sent from sourceforge.net because pd-dev(a)lists.iem.at is subscribed to http://sourceforge.net/p/pure-data/bugs/ To unsubscribe from further messages, a project admin can change settings at http://sourceforge.net/p/pure-data/admin/bugs/options.

Whose fault is this crash? (nan and inf)
by Kjetil Matheussen 10 Sep '13

10 Sep '13

This patch sometimes crashes PD: [0.0000000000000000000000000000000001 ( | [expr 1/$f1] | [env~] | [vd~ buffer 100] [delwrite~ buffer] The output of expr is inf. The output of env~ is nan vd~ doesn't always handle nan, and crashes. A fix for vd~ can look like this: --- a/pure-data/src/d_delay.c +++ b/pure-data/src/d_delay.c @@ -271,7 +271,11 @@ static t_int *sigvd_perform(t_int *w) t_sample zerodel = x->x_zerodel; while (n--) { - t_sample delsamps = x->x_sr * *in++ - zerodel, frac; + t_sample inval = *in++; + if(isnan(inval)) + inval = 0.0f; + + t_sample delsamps = x->x_sr * inval - zerodel, frac; In Pd, should objects be able to handle (i.e. "not crash") when they get input values of nan and inf, or should they instead make sure that nan and inf never can be sent out of the objects, or both?

dogensym voodoo
by Jonathan Wilkes 07 Sep '13

07 Sep '13

Hi list, Can someone explain the symhash voodoo in the dogensym function of m_class.c? To me it looks like sym1 could be referring to a location in the symhash array which isn't yet initialized, so I can't wrap my head around why sym2->s_name doesn't just crash Pd. Code below for easy reference: /* ---------------- the symbol table ------------------------ */ #define HASHSIZE 1024 static t_symbol *symhash[HASHSIZE]; t_symbol *dogensym(const char *s, t_symbol *oldsym) { t_symbol **sym1, *sym2; unsigned int hash1 = 0, hash2 = 0; int length = 0; const char *s2 = s; while (*s2) { hash1 += *s2; hash2 += hash1; length++; s2++; } sym1 = symhash + (hash2 & (HASHSIZE-1)); while (sym2 = *sym1) { if (!strcmp(sym2->s_name, s)) return(sym2); sym1 = &sym2->s_next; } if (oldsym) sym2 = oldsym; else { sym2 = (t_symbol *)t_getbytes(sizeof(*sym2)); sym2->s_name = t_getbytes(length+1); sym2->s_next = 0; sym2->s_thing = 0; strcpy(sym2->s_name, s); } *sym1 = sym2; return (sym2); }
