Issue 97 in cog: Sound on Linux
by cog＠googlecode.com 08 Aug '13

08 Aug '13

Status: Accepted Owner: siguc...(a)gmail.com Labels: Type-Defect Priority-Medium New issue 97 by siguc...(a)gmail.com: Sound on Linux http://code.google.com/p/cog/issues/detail?id=97 ... I had to replace the vm-sound-ALSA plugin that comes bundled in the 1.4 one-click image with the so.vm-sound-ALSA one that comes in Squeak 4.3. Couldn't we include that one by default? The one that comes with Pharo doesn't work and reports "could not find module vm-sound-ALSA". ... Looks like run-time link problems, because code we use for this plugin is same.

Issue 96 in cog: Using >> (bitShift:) instead of pow (raisedTo:)

Status: Accepted Owner: nicolas....(a)gmail.com Labels: Type-Enhancement Priority-Low New issue 96 by nicolas....(a)gmail.com: Using >> (bitShift:) instead of pow (raisedTo:) http://code.google.com/p/cog/issues/detail?id=96 By virtue of SLANG translation, interpreterAllocationReserveBytes uses pow((double)2,(double)n) to answer an int, wouldn't it better to just use a bit shift? 2^n <=> 1<<n, up to n=31 I doubt we reserve more than that, the result is signed anyway. And this would remove yet another warning. Attachments: interpreterAllocationReserveBytes.st 2.0 KB

Re: Issue 72 in cog: Don't open an Dialog on Mac in headless mode

Updates: Status: Accepted Cc: esteba...(a)gmail.com Comment #1 on issue 72 by sean.p.d...(a)gmail.com: Don't open an Dialog on Mac in headless mode http://code.google.com/p/cog/issues/detail?id=72 This is even more important now with the MBP retina. A "headless" cog image always forces the GPU to discrete mode, draining the battery. I often use headless (e.g. for Jenkins jobs and web scrapers) and in addition to the distraction of the unneeded window popping up, the switch to the power hogging GPU for no reason is even more of a drag.

[PATCH 1/3] ALSA: correctly handle -ESTRPIPE
by Daniel Drake 01 Apr '13

01 Apr '13

When ALSA produces -ESTRPIPE, it means that the sound subsystem is suspended, and the client should resume it if it wants playback to continue. See http://www.alsa-project.org/alsa-doc/alsa-lib/pcm.html#pcm_errors and sample code: http://www.alsa-project.org/alsa-doc/alsa-lib/_2test_2pcm_8c-example.html Fixes a sound failure (and huge log spam) after suspend/resume with sound playback enabled.
