Re: [Sugar-devel] wanting to try recent Sugar, problems
Excerpts from Anish Mangal's message of Wed Sep 01 13:32:55 +0200 2010: don't install Sugar distro packages and sugar-jhbuild in parallel on the same VM, it'll cause trouble). Can you elaborate what would be the nature of these problems? For distro packages vs. sugar-jhbuild issues in general, see SL#111 [1] and SL#2304 [2]. I don't remember any written record of Glucose distro packages (as opposed to GConf-dbus) breaking anything, but seem to remember I've hit it during testing once. This kind of issue is usually rather hard to detect and diagnose, so it's better to simply not try it. If you still try it and find out that sugar-jhbuild needs to do something (usually setting an environment variable) to make something in sugar-jhbuild preferred to the same thing in the distro, please file a bug on bugs.sl.o [3]. I've been trying to get a clean jhbuild env to work under f13. gabble/salut don't work when I run the sugar-emulator. and I can't share activities. To test whether is this was a system-wide problem, I installed the sugar-* rpm's as well. The package-installed sugar-emulator starts up well; gabble/salut don't crash and I can get activities to be shared. Your particular problem stems from the fact that the latest development version (i.e. git HEAD) has had Tomeus Remove Presence Service [4] Feature landed which requires the very latest (not yet packaged) releases of several Telepathy components.

The reproducible instance is /media/disk/dev/fd/24 ... since fd is a
symlink to /proc/self/fd ... (awesome isn't it? One can insert a USB key
that will list the contents of any directory on the laptop, provided
access is allowed.)
Ah, it's good that came up during testing, didn't think about it. We
should make sure symlinks don't point outside the filesystem by resolving
them (os.path.abspath()) and checking against the root path.
Agreed. ENOTDIR removed and os.path.abspath added.
os.lstat of an entry returned by os.listdir
[...]
exception EIO a total of 7 times
Interesting. Was the storage medium broken in some way (read error)?
I don't even see EIO as a documented error code for lstat(2).
Yes, storage medium is broken. It is a USB HDD with reallocated sectors
and no spare area sectors available, or with a pending unstable sector
waiting to be remapped. dmesg shows:

The drive itself is reasonably old and should have completely failed
long ago.
Why? The order in which os.listdir() returns the entries is undefined
anyway.
When one uses os.listdir and then reverses the order before going
through them, the resulting performance is low, since the files are
being accessed in reverse. Because I didn't know about pop(0), I had to
use .reverse() to maintain ordering.
Ah, don't you love how undefined behaviour still affects performance?
I think that's quite expected, especially since performance is equally
undefined. Although the order may not be defined, there is likely to be
an ordering imposed by the underlying implementation.
[_scan()]
+if len(self._pending_files) 0:

PEP-8 says we should use if self._pending_* instead (without len()).
If we just call the functions and return True in _scan(), we don't
need to ensure that we always return True in self._scan_a_*().
Thanks, taken both points.

Re: [Sugar-devel] Feedback about ticket #10122
Hi Benjamin Thanks for review. I don't know if you have time now, but I can devote a few hours to Distance. I understand your concern about the volume change. Maybe the right answer is to print some warning text if the system volume is too low. I think a better patch would probably show the user the amplitude of the last received signal and the noise floor. This is easy to measure, but I'm not sure how to display it in the GUI. If you can tell me how detect the volume from the signal it's not enough to make a measurement, i can try to work in the interface work. Do you dislike the semaphore idea? May be use icons?

I can't easily test changes because my XO-1.5 is broken, but maybe I can fix it this weekend. Ok. Tell me if I can send you more information. There are changes I did based in my tests, but I need to know if you agree. I'm concerned about any making Distance change the volume settings. This might make sense for the microphone amplification setting, but I would prefer to leave the speaker volume under the user's control. The appropriate volume to use for Distance depends on how long a distance one is trying to measure, the level of background noise, whether other people might be disturbed, etc. I was thinking we can show a semaphore or any image with the quality of the measure, in base of the difference with the previous measurements. For example if the difference with the last is until 5% different its green , until 30% yellow, more is red. Also we can put a text suggesting turn up the volume for better results. The changes in delay constant could make sense. I'll need to look at the changes and see if we can find an explanation for the changes. Other problem I am having is (in Sugar 0.84) if I restart a previously shared activity, the activity starts shared, but not appears in the neighborhood view from the other machines. I need to start a new activity and then share. Also I don't know if it's a good idea Distance save in the Journal. Only saves the temp and humid values and the last measurement. May be we can save these values in the activity_root/data directory from the activity, not pollute the Journal and resolve the resume issue. What you think? The change is easy.

I agree, but I thought the original poster was saying that the problem was caused by the update to 10.1.2 ... looking back through that post and examining 8.2.1 only the vnc and vnc-libs packages are installed, providing the vncviewer binary, yet on 10.1.2 the binary is not present. That may be an issue for 10.1.3, but I've not heard any request for it yet. VncLauncher doesn't use the vncviewer binary; it is a VNC server activity. It embeds an x11vnc binary and associated libraries. I don't see how this problem was caused by 10.1.2, so I remain curious. -- James Cameron http://quozl.linux.org.au/ ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

Thanks a lot for these instructions.

If you have a schoolserver, then you should already have daily backups
even with 802. You're just missing a restore function.
Interesting, I wasn't aware of that.
If I remember correctly I had set up XS 0.5 at the school, how would I find
out whether the backups were made and if so how do I restore them to the XOs
after I install Dextrose on them?
Thanks again for all your help,

[Sugar-devel] [PATCH sugar-0.84] fix journal scan of external media, dev.laptop.org #10140
Update the progress bar regularly and prevent the UI from stalling
during a scan.
Avoid following recursive symlinks, and symlinks that point outside the
filesystem being scanned.
Check for MIME type of file last, to improve performance.
Do not report permission denied errors.
