Measure 24 does not launch on F11

[walter]

Mikus Grinbergs reported that when he tried launching measure, its "activity launch" screen pulsed for a while, then vanished. Nothing else happened. (F11 running on XO hardware).

[arjs]

code in audiograb.py is hard-linked to the names of the alsa controls in the XO alsamixer and a good first step would be to abstract that.
Help from someone to fix-code this would be great.

[walter]

Could you please try version 27 and report back?

[DeanBrettle]

Patch to support envs where some mixer controls (e.g. PCM and Mic) don't exist

[DeanBrettle]

Version 29 fails with the same error on F12. The patch I just attached fixes it.

[walter]

I've applied a slight variant to Dean's patch: I only catch ValueErrors with the exception handler. I'll attach v-30 for testing and if it seems to be OK, I'll post it to ALSO.

(Sorry it took me so long to get back to this... too many other distractions of late.)

[bernie]

Measure 29 seems to work fine on F11-XO1. It fails to start in jhbuild with F12, though.

[walter]

Hey bernie, how about some log files so I can diagnose the problem.

-walter

[walter]

I am assuming that #1367 will address these problems as well.

[walter]

Sorry to have taken so long to get this sorted out... I am running v30 on F11 and F13 successfully. I will be pushing F30 to ASLO and closing this ticket. Note that there are some issues being tracked in #2035.

[walter]

err. s/F30/V30

Available in git, but not yet ASLO.

[bernie]

If you bundle it up, I'll test today.

[walter]

I attached a new version of v30 t this ticket. It should launch and work on the F11 build for XO 1.5. It will launch on F11 builds for XO 1.0, but we need to test whether or not sensor mode will work. It will not launch on F9 builds, It should launch on F13 (SoaS) builds. Please attach log files for any failed launches.

[walter]

I should have noted that this is not the final release version of Measure-30. There are some toolbar improvements queued up as well as some work to be done to ensure it launches on old systems without gst mixer support.

[bernie]

I tested with F11-0.88 on both XO-1 and XO-1.5.

On the XO-1.5, sound input is totally out of range and looks random. Proably a platform issue, not a bug in Measure.

What should be happening when I click Start Recording in the Sensors toolbar? On both platform, I see odd numbers on the toolbar while the mic light remains off.

[bernie]

Replying to bernie:

What should be happening when I click Start Recording in the Sensors toolbar? On both platform, I see odd numbers on the toolbar while the mic light remains off.

Oh, wait... maybe I'm seeing the old "privacy bug" of the XO board: the mic light stays off if you bypass the high-pass filter while sampling.

[walter]

This version has some patches to clean up various bits and it has some improved backward compatibility in the audiograb.py section. Still inconclusive sensor results on F11/OLPC 1.0 hardware.

[walter]

The current version should work on F11 0.84/0.88 on both XO 1.0 and XO 1.5 hardware. Please test.

[walter]

The version I just uploaded seems to work on XO 1.0 and XO 1.5 with F9 and F11. The calibration is a bit better. (Note: the humidity sensor seems to behave differently on the different hardware and the output of the light sensor is inverted between machines.) There is an occasional Pango error in displaying the sensor value that I cannot seem to properly characterize. Yet this is about usable. Please test.

[jasg]

I tried it. The result was: the activity works for a while and after it stop suddenly. Attached the log file.

[walter]

The crash seems to be related to writing the sample value to the toolbar label... Not sure of the root cause :(

[walter]

I think that by adding gtk.thread wrappers around the value display prevents the crash reported by jasg. I also added support for 0.86+ toolbars. Please test.

[walter]

Replaced sleep calls with gobject.timeout_add in attempt to fix problem with hanging.
Fixed? issue with gconf on F7 systems.

[walter]

Still something wrong with the mixer or parameter settings: when cycling between sound and sensor toolbars, the levels change.

[carrott]

Latest measure-30 has the trigger control visible on 8.2.1 on XO-1! Thank You Walter

[walter]

Ah, but does it work? Please test it.

[walter]

added missing tooltips, fixed some typos

[walter]

Measure 30, just released, does open on F11... closing this ticket.
