I agree. Both http and https downloads could be supported by using relative paths in the html a tags: <a href="/Software/$$$"> This should work as the site host is msp.ucsd.edu <http://msp.ucsd.edu/> and the relative path would be append: http or https + :// + msp.ucsd.edu <http://msp.ucsd.edu/> + /Software/$$$ > On Oct 25, 2023, at 12:00 PM, pd-dev-request(a)lists.iem.at wrote: > > Message: 2 > Date: Tue, 24 Oct 2023 23:42:54 -0300 > From: Lucas Cordiviola <lucarda27(a)hotmail.com <mailto:lucarda27@hotmail.com>> > To: mpuckette(a)cloud.ucsd.edu <mailto:mpuckette@cloud.ucsd.edu> > Cc: pd-dev(a)lists.iem.at <mailto:pd-dev@lists.iem.at> > Subject: [PD-dev] https, msp.ucsd.edu <http://msp.ucsd.edu/> and file downloads. > Message-ID: > <IA1PR19MB7663C08254A20320483350BEA6DEA(a)IA1PR19MB7663.namprd19.prod.outlook.com <mailto:IA1PR19MB7663C08254A20320483350BEA6DEA@IA1PR19MB7663.namprd19.prod.outlook.com>> > > may be the safer way to allow links to work on both types of connections > (http and https) is to give relative URLs (stripping 'http://msp.ucsd.edu <http://msp.ucsd.edu/>') > > ??? <a href="./$$$"> > -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

https, msp.ucsd.edu and file downloads.
by Lucas Cordiviola 25 Oct '23

25 Oct '23

Miller, this might leave many (using the latest chrome web browser) scratching their heads: if I follow instructions to get the latest Pd from https://msp.ucsd.edu/software.htm when i click to download any of the files nothing happens and no files get downloaded. If I start a console I see: ``` software.htm:1 Mixed Content: The site at 'https://msp.ucsd.edu/' was loaded over a secure connection, but the file at 'https://msp.ucsd.edu/Software/pd-0.54-1test1.windows-installer.exe' was redirected through an insecure connection. This file should be served over HTTPS. See https://blog.chromium.org/2020/02/protecting-users-from-insecure.html for more details. ``` i think the problematic redirection happens in the links in file `software.htm` : <a href="http://msp.ucsd.edu/$$$"> where 'http' is used. --- may be the safer way to allow links to work on both types of connections (http and https) is to give relative URLs (stripping 'http://msp.ucsd.edu') <a href="./$$$"> there might be other ways. --- if i use the non-secure site all files can be downloaded normally. -- Mensaje telepatico asistido por maquinas.

Re: [PD-dev] time for a quick bugfix update?
by Dan Wilcox 23 Oct '23

23 Oct '23

I will try to check this tonight as we may/may not need to update the custom patches which are applied when building Tk for Pd. IN general, I think it's a good idea to make a 0.54-1 bugfix release for this as well as include the small changes in the develop branch which include a fix required for libpd... then I can make a libpd release too. > On Oct 22, 2023, at 12:00 PM, pd-dev-request(a)lists.iem.at wrote: > > Message: 1 > Date: Sat, 21 Oct 2023 13:57:07 -0300 > From: Alexandre Torres Porres <porres(a)gmail.com <mailto:porres@gmail.com>> > To: pd-dev <pd-dev(a)lists.iem.at <mailto:pd-dev@lists.iem.at>> > Subject: [PD-dev] time for a quick bugfix update? > Message-ID: > <CAEAsFmjyVNDQXX7oHGNWw=43LS_aTcAhr1Z-8C=bTnLB7JhzTQ(a)mail.gmail.com <mailto:CAEAsFmjyVNDQXX7oHGNWw=43LS_aTcAhr1Z-8C=bTnLB7JhzTQ@mail.gmail.com>> > Content-Type: text/plain; charset="utf-8" > > Hi, we have an issue with the latest macOS, see > https://github.com/pure-data/pure-data/issues/2105 > > It seems an upgrade of tcl/tk is required and it would be worth a bugfix > release as I see it.

time for a quick bugfix update?
by Alexandre Torres Porres 21 Oct '23

21 Oct '23

Hi, we have an issue with the latest macOS, see https://github.com/pure-data/pure-data/issues/2105 It seems an upgrade of tcl/tk is required and it would be worth a bugfix release as I see it. What do people say? cheers

myfft~.c:2:10: fatal error: fftw3.h: No such file or directory
by Alexandros Drymonitis 20 Oct '23

20 Oct '23

I'm trying to create an external to test if I can embed [rfft~] and [rifft~] in one object. This is just a test to see if I can get this right, before I implement this to another external. I'm stripping what I think is necessary from Pd's source code, but I already get the error in the subject line. The FFTW3 library is used by Pd, and it is #included in the d_fft_fftw.c file. I have compiled Pd myself, and no such error occurred, so, this file must be somewhere in my system. Any idea how to solve this?

Object crashes when trying to write to its outlet
by Alexandros Drymonitis 10 Oct '23

10 Oct '23

I'm trying to code an object with a variable number of inlets and outlets, that's more complex than the one I posted a few days ago. Writing to its input works fine, but when I try to write to its output, Pd crashes. The culprit is when I try to access each individual output. In the new routine, I allocate memory likes this: ``` x->x_in = (t_sample **)getbytes(ninlets * sizeof(t_sample *)); x->x_out = (t_sample **)getbytes(noutlets * sizeof(t_sample *)); for (i = 0; i < ninlets; i++) x->x_in[i] = (t_sample *)getbytes(x->x_blksize * sizeof(t_sample)); for (i = 0; i < noutlets; i++) x->x_out[i] = (t_sample *)getbytes(x->x_blksize * sizeof(t_sample)); ``` But Pd crashes when I try to access any output other that x->x_out[0][0]. In a function that is called by the perform routine, I do the following: ``` for (i = 0; i < x->x_noutlets; i++) { x->x_out[i][x->x_sample_index] = (t_sample)x->x_outvec[i]; } ``` and Pd crashes. Debugging with gdb pointed to this line. Changing the code to x->x_out[0][0] does not crash Pd. I have also confirmed that x->x_outvec[i] is not crashing Pd. Since memory for x->x_out has been allocated, and since I'm not trying to access an element beyond this allocated memory (which is also confirmed), why does Pd crash? Or am I doing something wrong in the memory allocation part?

help coding an object, I need it cause I don't know better
by Alexandre Torres Porres 10 Oct '23

10 Oct '23

Hi, I'm working on a new object that is kinda like [value], but much simplified and you can set multiple variable names and output them all as a list (only floats now). It's been fun and it was working, compiling with some weird bugs. I then started revising it and when I thought I could be fixing the last bug, code does not compile now. What I'm doing is storing multiple variable values and variable names, just like I'm doing with some float values for my new multichannel aware audio objects (one value per channel). So I have. *typedef* *struct* _var{ t_object x_obj; t_int x_n; // number of given vars as arguments t_symbol **x_sym; // variable name *float* *x_fval; // var value }t_var; Now, when initializing the variable, in "new", I am trying to get the value of an existing variable name (which is created if it doesn't exist yet). This is done in the same as in [value] by the way In [value] you have x->x_floatstar = value_get(s); I got x->x_fval[i] = var_get(x->x_sym[i] = atom_getsymbol(av+i)); But this gives me the error * *var.c:80:22: **error: **assigning to 'float' from incompatible type 't_float *'* * (aka 'float *'); dereference with ** x->x_fval[i] = var_get(x->x_sym[i] = atom_getsymbol(av+i)); * ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~* Funny enough, I had an older version that would compile and work very well despite some crashes, that initialized x_fval as *float* **x_fval; // var value Instead of just "*x_fval", which doesn't seem right. Please help, and also, at this time, I could take suggestions of some nice and free online C course that would make me intelligent to the point I would have a minimum idea of what I am doing. thanks

how to output list with selector
by Alexandros Drymonitis 21 Sep '23

21 Sep '23

I'm trying to output a list of values with a selector. For example, "foo 1 2". I though of creating a vector of t_atom, where a_type of the first element would be A_SYMBOL, and the other two would be A_FLOAT, and after a list outlet is created in the new method like this: `x->outlist = outlet_new(x->x_obj, &s_list);` I can output the list with a bang like this: `outlet_list(x->outlist, &s_list, 3, x->outlist)`; But Pd complains with this error: ``` print: listconsistency check failed: atom_string consistency check failed: atom_string consistency check failed: atom_string ``` What I would like, is to get the output of the object and route it with [route foo]. How do I go about this?

external crashing when block size changes
by Alexandros Drymonitis 20 Sep '23

20 Sep '23

I'm trying to create a signal external with a variable number of inlets and outlets. As a test, I have written an object that copies its input to the respective output. When I put the object in a subpatch and use [block~] to change the block size, it crashes. Loading Pd with gdb gives the following output, which to me doesn't seem very helpful: ``` Program received signal SIGSEGV, Segmentation fault. 0x0000000000000000 in ?? () ``` Here's the code of the object (the var_io_tilde_process function is there as a test to see if I can process the output in a routine other than the perform one): ``` #include <m_pd.h> static t_class *var_io_tilde_class; typedef struct _var_io_tilde { t_object obj; t_sample f; t_sample **in; t_sample **out; t_sample *buf; int chnls; int blksize; int bufbytes; } t_var_io_tilde; static void var_io_tilde_process(t_var_io_tilde *x, int n) { int i, j; t_sample **out = x->out; t_sample *buf = x->buf; for (i = 0; i < x->chnls; i++) { for (j = 0; j < n; j++) { out[i][j] = buf[i*n+j]; } } } t_int *var_io_tilde_perform(t_int *w) { int i, j, n; t_var_io_tilde *x = (t_var_io_tilde *)(w[1]); n = (int)(w[2]); t_sample **in = x->in; //t_sample **out = x->out; t_sample *buf = x->buf; for (i = 0; i < x->chnls; i++) { for (j = 0; j < n; j++) { buf[i*n+j] = in[i][j]; } } var_io_tilde_process(x, n); return (w+3); } void var_io_tilde_dsp(t_var_io_tilde *x, t_signal **sp) { int i; int bufbytes = x->bufbytes; t_sample **dummy = x->in; for (i=0; i<x->chnls; i++) *dummy++ = sp[i]->s_vec; dummy = x->out; for (i=x->chnls; i<x->chnls*2; i++) *dummy++ = sp[i]->s_vec; if (x->blksize != sp[0]->s_n) { x->blksize = sp[0]->s_n; x->bufbytes = x->chnls*2*sp[0]->s_n; x->buf = (t_sample *)resizebytes((void *)x->buf, bufbytes, x->bufbytes); if (x->buf == NULL) { pd_error(x, "cannot realloc %d bytes of memory", x->bufbytes); return; } } dsp_add(var_io_tilde_perform, 2, x, sp[0]->s_n); } void *var_io_tilde_new(t_floatarg f) { int i; t_var_io_tilde *x = (t_var_io_tilde *)pd_new(var_io_tilde_class); x->chnls = (f) ? f : 2; x->blksize = sys_getblksize(); /* create signal inlets (first is done in var_io_tilde_setup) */ for (i=1; i<x->chnls; i++) inlet_new(&x->obj, &x->obj.ob_pd, &s_signal, &s_signal); /* create signal outlets */ for (i=0; i<x->chnls; i++) outlet_new(&x->obj, &s_signal); x->in = (t_sample **)getbytes(x->chnls * sizeof(t_sample **)); x->out = (t_sample **)getbytes(x->chnls * sizeof(t_sample **)); for (i=0; i<x->chnls; i++) x->in[i] = x->out[i] = 0; x->bufbytes = x->chnls*2*x->blksize; x->buf = (t_sample *)getbytes(x->bufbytes * sizeof(t_sample *)); return (void *)x; } void var_io_tilde_free(t_var_io_tilde *x) { freebytes(x->in, sizeof(x->in)); freebytes(x->out, sizeof(x->out)); } void var_io_tilde_setup(void) { var_io_tilde_class = class_new(gensym("var_io~"), (t_newmethod)var_io_tilde_new, (t_method)var_io_tilde_free, sizeof(t_var_io_tilde), CLASS_DEFAULT, A_DEFFLOAT, 0); class_addmethod(var_io_tilde_class, (t_method)var_io_tilde_dsp, gensym("dsp"), 0); CLASS_MAINSIGNALIN(var_io_tilde_class, t_var_io_tilde, f); } ``` What am I doing wrong? And, if this is not the way, how can I create an object with a variable number of inlets and outlets (preferably independent of one another).

How to check data type of arguments in object
by Alexandros Drymonitis 13 Sep '23

13 Sep '23

I'd like to write an object that takes a variable number of arguments, which can be either float or symbol, and in any order (for example, float float symbol, or symbol float). How can I check the data type of each argument inside the new routine?
