/* $Id$ */ --- make the development process more test-driven: * file every feature request and bug report into base/test.rb so that gridflow fails those tests; * THEN make gridflow pass those tests. for 0.7.7: [ ] GF with Pd 0.36 : undefined pd_newest for 0.7.8: [ ] [#reverse] [ ] [#change] [ ] we're switching to PD for abstractions, instead of Ruby. Make a new bunch of them. Add a video latency patch (in examples) [ ] consider including [mysql] [renamefile] [ls] [shell] for 0.7.9: ? for 0.8.0: * added #matrix_solve, #slice * Copy-on-Write (COW) * Numop API exposed to Ruby * < 10 bugs in buglist * Fully hyperlinked manual * internals documentation * internal grid protocol redesigned * [#export~] * raise limit of in/outlets from 10 to 100 or unlimited. for 0.8.1: * wrap Pd API completely. * drop the :whatever part. Bugs (High Priority) (!!! Fix all of these before 0.8.0 !!!) pick a number: [147] [146] [#peephole] resize problem [145] "list -1"->[@import] only tells error message once every other time [144] small leak remaining in x11. may have to do with non-use of XDestroyImage. [141] shouldn't be able to call Pd from a non-main Ruby thread. [140] is [@convolve] actually cross-convolution? that is, convolves with a mirror image of the convolution matrix. [139] [#peephole] matju: BUG-ALERT - peephole does not delete until a screen refresh matju: I was just about to do that matju: it works... almost matju: if you try to move the GOPed abstraction the peepholes don't move along he :) better yet, the abstraction's bounding box's lower right corner will not move up or to the left of the low right corner of the peephole it contains. Instead it will resize itself as you move it around. [138] [#peephole] crash [137] [gf] peeperr: problem with set_geometry, wrong size. [136] fix C_INCLUDE_PATH vs CPLUS_INCLUDE_PATH [134] #import with zero size crashes? [133] numop ** can freeze GF [129] jmax2pd: [display] should be translated to [messageprepend set] -> "" [128] jmax2pd(?): loadbang-messages (comma) don't get translated to .pd ?? [119] osx: SDL doesn't work here [118] error messages can be unclear (eg. file not open... is it #in's, or #out's?) [117] osx: [#store] crash instead of raising [115] x11: dual display does not work (screens .0 vs .1; but xinerama works fine) [112] Pt: some casts aren't done properly [107] MMX computations may be done misaligned, which may be bad. [105] when file not found, mpeg error messages are wrong, they say the filename is "". [102] osx: error: shmget failed (cannot allocate memory) in X11, for regular pictures [100] osx: libgridflow.so installs in wrong directory (of course) [090] doesn't check whether ruby/version.h matches .so / .a [027] tcp test is broken [089] is LINK TO="..." not properly handled? see part of install.xml that uses it. [088] FIX MOULINETTE.RB ! [078] "unsupported codec" bogus errors. [097] bin/backtrace does not detect scripts [005] can't open "": Success; loading a nonquicktime file using quicktime [006] #in#open problem with String argument. [010] separate bridge makefiles from other makefiles!!! [011] research bugs in nonblock IO with Ruby. (eg. serial port) [025] format_grid: write test for other bpv's [026] latency is not that good. (GC ?) [030] FormatGrid: not properly tested (crashes sometimes) [031] stdout should be redirected if bridge is present [032] error handling sometimes leads to crash [033] error handling shows inanely useless messages (sometimes) [034] format/mpeg3.c,quicktime.c might cause lockup on exit [037] new "seed"s may leak ? (Grid vs Grid*) [038] some seeds aren't typechecked [039] jpeg file cat crashes on second file (jpeglib buffering?) [040] GRID_FINISH triggered while backstore ??? Bugs (Low Priority) [079] can trap segfaults in codecs of libquicktime. [090] http://poynton.com/notes/colour_and_gamma/ColorFAQ.html#RTFToC30 [076] EINTR not handled properly in a lot of code? [041] what would be a way to make GF work well with Pd's idea of a list? [043] TCP server socket busy even after kill [045] write unit tests about required functionality [046] write unit tests about error checking [047] make system to ensure everything is working before a release. [048] potential issues between fork() and X11 ? [050] BitPacking has trouble with masks that extend beyond int25be [051] remove the crap given by -w of ruby [054] it's possible to crash by sending data in two inlets of a same object at once [059] mess with options in format grid [060] look for "!@#$" in source [029] #join on small chunks is way too slow [009] T_DATA #dup #clone ???

Feature Requests From: Dave Bergevin [ ] synchronized audio with the video when using mpeg1 & 2 [ ] full screen mode (without the menu bars or frames) From: Alexandre Castonguay [ ] support for tcp/ip connections to control pd objects (from a web interface) [ ] server side pd to handle multiple incoming commands, audio + video streams [ ] support for audio in the mpeg streams alx_away: le tab completion ne donnerait pas seulement les noms possibles pour le prochain argument dans le objectbox; il donnerait aussi une description de l'argument (surtout dans le cas où l'argument a beaucoup de valeurs possibles) je pense que le help de Pd est une bonne idée (le concept hands-on) mais ça pourrait aller plus loin. j'ai pensé intégrer le manuel de référence de gridflow directement dans le programme, disponible au runtime, dans l'éventualité d'un GUI qui saurait en tirer avantage. sinon on pourrait faire des hacks cool genre un message "help" au inlet 0 enverrait une description de la classe dans le log. (sauf que dans ce cas: [rubyprint] est tenu d'afficher directement tout ce qu'il reçoit. alors doit-il écrire "help" ou écrire le help ? alx1->matju: détection de plusieurs personnes; détection avec deux caméras (?); détecter les formes; détecter les couleurs; support mpeg4; hotspots matju: another feature for the summer : select file to load via a navigable menu as in 'file/open' alx1: this is not a feature i can put in gridflow. if you want it, then i can make one for pd, but it does not make sense to add it to gridflow itself. > http://redshift.sourceforge.net/debugging-GC/ [ruby-talk:53835] > You might also want to search the web for "malloc debugger". debugging: gdb `which ruby` ---------------------- break main run -rgridflow -e ';' set step-mode on break eval.c:5409 cont add-symbol-file /usr/local/lib/ruby/site_ruby/1.6/i686-linux/gridflow.so rbreak ^_init stepi ---------------------- p dlopen("/opt/lib/ruby/site_ruby/1.8/i586-linux/gridflow.so",0) ... I am Jack's Overwritten Stack Pointer... Tcl_GetObjResult Tcl_GetErrorInfo ... Tcl_GetStringResult may also be helpful. (note I can't seem to find Tcl_GetErrorInfo (maybe I dreamed it up)) matju: BTW CatchObjCmd might help too I see that the new Tcl_Dict commands have taken over the HEAD's CatchObjCmd ClaudiusMaximus reports that allocating a 197M grid causes a crash (turns out C++ throws exception, can't allocate, signal ABRT) ClaudiusMaximus says: I want to be able to send output from Pd+Gridflow to a video4linux loopback device so that other v4l programs can access the stream. I found the video loopback device here: http://motion.sourceforge.net/vloopback/ matju: iSight on linux : http://episteme.arstechnica.com/6/ubb.x?a=tpc&s=50009562&f=8300945231&m=40110681 matju: apparently it needs something called 'coriander'...I'm checking into it matju: the person who got it working mentions libdc1394 matju: ah coriander is a GUI for firewire matju: on this page : http://www.tele.ucl.ac.be/PEOPLE/DOUXCHAMPS/ieee1394/cameras/index.html matju: I learn that the iSight is compliant with version 1.30 of IIDC matju: the docs for coriander mention that the author needed to create a major and minor device for the camera. matju: retyping (damn pdf's) -> there are two devices to create: raw1394 and video1394 matju: raw1394 has major 171 and minor 0 while video1394 had major 171 and minor 16 thanks matju: any useful info? i'll see, doing something else at the moment matju: having a camera like the iSight supported could be fantastic for video capture/detection on a laptop. Not to mention that the bttv cards are getting harder to locate -mfpmath=sse2 alx2: btw you cannot set helpfiles explicitly on _abstractions_... yes you can and specify -helppath to add a path to help. So selecting 'Help' in the pop-up on an abstraction will open a help fiel for that abstraction
