PI 1.08 core dump and error dialogues
« on: 2012 December 25 21:06:59 »
Hey.

Struck a few bugs it seems.

1) Have managed to core dump PI 1.08 a couple of times.
Ubuntu Linux 12.04 x86_64, with latest patches, 8GByte RAM, oldish mobo, AMD Athlon(tm) 7750 Dual-Core Processor, 2.879GHz.

terminate called after throwing an instance of 'pcl::EUnixSegmentationViolation'
./PixInsight.sh: line 9: 18977 Aborted                 (core dumped) $dirname/$appname $*

terminate called after throwing an instance of 'pcl::EUnixSegmentationViolation'
./PixInsight.sh: line 9: 22922 Aborted                 (core dumped) $dirname/$appname $*

Most recently it was doing a curves transform with preview window up.

2) Have had several Error dialogue boxes appear. Generally they look like "Error writing settings data (QByteArray)" or "Error writing settings data (Boolean)"
This happens when I try to load previously saved process icons (e.g. the noise reduction process icons from one of the threads here) - QByteArray
The other one (Boolean) is happening when I try to close any window - e.g. a process window or even PI itself. Once PI is closed, I get a "PixInsight API Error" "Settings: Error writing local integer data: Interfaces/AdaptiveStretch/Geometry/Left API error code = 3: Invalid module handle"

I don't think that these relate to my specific install, although when I untarred the distrib, I got a lot of;
  tar: Ignoring unknown extended header keyword `SCHILY.dev'
  tar: Ignoring unknown extended header keyword `SCHILY.ino'
  tar: Ignoring unknown extended header keyword `SCHILY.nlink'
  tar: Ignoring unknown extended header keyword `LIBARCHIVE.xattr.security.selinux
errors.

Cheers -
(edited to include #2 above)

Hi,

Thank you for your bug reports.

(1) Are you using GNOME 3? (I would say yes, since it's the default GNOME version in Ubuntu 12.04). Unfortunately, we don't support GNOME 3. The PixInsight application will launch, but you may expect all kinds of problems with the graphical interface (especially top level tool windows), which in turn may unstabilize the whole platform.

The officially supported desktop environments for PixInsight on X11 (FreeBSD and Linux) are the following:

* KDE 4.7 or later (preferably the latest versions of KDE 4.8.x)
* GNOME 2.x
* Xfce 4.x
* LXDE

The recommended desktop environment is KDE, where PixInsight is primarily being developed.

(2) Could you please post one of those XPSM icon files that are giving you problems? That would help me to diagnose the problem.

(3) You can safely ignore all of those tar messages. They are related to SELinux extensions, which are enabled on the systems we use to build and distribute PixInsight installation packages.

Thanx Juan.

Hi,

Thank you for your bug reports.

(1) Are you using GNOME 3? (I would say yes, since it's the default GNOME version in Ubuntu 12.04). Unfortunately, we don't support GNOME 3. The PixInsight application will launch, but you may expect all kinds of problems with the graphical interface (especially top level tool windows), which in turn may unstabilize the whole platform.

Ahhhh. Yes, would appear to be Gnome 3. Have had the odd UI thing happen in the past that I haven't mentioned as well, most likely Gnome 3 related. I'll hunt down an alternative/supported window manager.


(2) Could you please post one of those XPSM icon files that are giving you problems? That would help me to diagnose the problem.

I think I've solved this problem. Upgrading under sudo (or rather, installing using sudo) created ~steve/.PixInsight/PixInsight64.conf but owned as root. I.e.. settings file in local user dir, but owned by root. Future runs of PI as local user (not sudo) was failing to update settings file, very often it seemed. These seem to be the dialog warnings I was getting.

I've repeated things recently many times, and not seen this re-occur.


(3) You can safely ignore all of those tar messages. They are related to SELinux extensions, which are enabled on the systems we use to build and distribute PixInsight installation packages.

Excellent, thanx.
