** Description changed: Version info: vince@uranus:/proc$ lsb_release -rd Description: Ubuntu 10.04.1 LTS Release: 10.04 vince@uranus:/proc$ uname -a Linux uranus 2.6.32-25-generic #44-Ubuntu SMP Fri Sep 17 20:26:08 UTC 2010 i686 GNU/Linux All apache packages: 2.2.14-5ubuntu8.2 Symptoms are that Lightning shows a warning ! against webDAV calendars and the popup message says: The calendar xxxxx is momentarily not available The calendar grid shows no events/actions from the webDAV calendars affected. The Error Console shows the following message for each webDAV calendar: Warning: There has been an error reading data for calendar: xxxxx. Error code: CAL_UTF8_DECODING_FAILED. Description: An error occured while decoding an iCalendar (ics) file as UTF-8. Check that the file, including symbols and accented letters, is encoded using the UTF-8 character encoding. When a webDAV .ics calendar file is downloaded via HTTP (Firefox) then viewed (with Notepad on XP client), it appears to contain spurious extra characters at start of file. These are not present in the underlying file as viewed locally on the Apache server machine. gedit on Lucid client baulks at displaying the downloaded file reporting that file appears to contain non-UTF-8 data. Example: Underlying file actually starts: --------------------------------------- BEGIN:VCALENDAR PRODID:-//Mozilla.org/NONSGML Mozilla Calendar V1.1//EN VERSION:2.0 X-WR-CALNAME:home X-WR-TIMEZONE:Europe/London BEGIN:VTIMEZONE TZID:Europe/London X-LIC-LOCATION:Europe/London BEGIN:DAYLIGHT TZOFFSETFROM:+0000 TZOFFSETTO:+0100 TZNAME:BST DTSTART:19700329T010000 RRULE:FREQ=YEARLY;BYDAY=-1SU;BYMONTH=3 END:DAYLIGHT <remainder of file snipped> --------------------------------------- File presented via webDAV starts: --------------------------------------------- 7‘0lðIæŸZ E „Fƒ@ @ À¨À¨ P´4€ž»u ™óF€ |ƒ\ ‰ F}HTTP/1.1 200 OK Date: Wed, 29 Sep 2010 09:50:02 GMT Server: Apache/2.2.14 (Ubuntu) Last-Modified: Wed, 15 Sep 2010 19:15:06 GMT ETag: "12c56b-771b-4905125b1c280" Accept-Ranges: bytes Content-Length: 30491 Keep-Alive: timeout=15, max=99 Connection: Keep-Alive Content-Type: text/calendar BEGIN:VCALENDAR PRODID:-//Mozilla.org/NONSGML Mozilla Calendar V1.1//EN VERSION:2.0 X-WR-CALNAME:home X-WR-TIMEZONE:Europe/London BEGIN:VTIMEZONE TZID:Europe/London X-LIC-LOCATION:Europe/London BEGIN:DAYLIGHT TZOFFSETFROM:+0000 TZOFFSETTO:+0100 TZNAME:BST DTSTART:19700329T010000 RRULE:FREQ=YEARLY;BYDAY=-1SU;BYMONTH=3 END:DAYLIGHT <remainder of file snipped> --------------------------------------- Now, possibly coincidentally, this problem apparently started immediately after I migrated my Apache server system from an old 600MHz Pentium II system to a new dual core Celeron E1200 system. Migration involved little more than moving the system disk from one box to the other. I see other bugs reported on Apache2 SSL involving corruption some of which refer to a gcc bug affecting code generation for SSE4 cpus so here is cpuinfo for Apache2 server cpu: vince@uranus:/proc$ cat cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Celeron(R) CPU E1200 @ 1.60GHz stepping : 13 cpu MHz : 1200.000 cache size : 512 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts aperfmperf pni dtes64 monitor ds_cpl est tm2 ssse3 cx16 xtpr pdcm lahf_lm bogomips : 3199.76 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Celeron(R) CPU E1200 @ 1.60GHz stepping : 13 cpu MHz : 1200.000 cache size : 512 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 apicid : 1 initial apicid : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts aperfmperf pni dtes64 monitor ds_cpl est tm2 ssse3 cx16 xtpr pdcm lahf_lm bogomips : 3199.99 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: + --- + AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21. + Architecture: i386 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: vince 1826 F.... pulseaudio + CRDA: Error: [Errno 2] No such file or directory + Card0.Amixer.info: + Card hw:0 'Intel'/'HDA Intel at 0xfdff8000 irq 16' + Mixer name : 'Realtek ALC883' + Components : 'HDA:10ec0883,1458c603,00100002' + Controls : 40 + Simple ctrls : 22 + DistroRelease: Ubuntu 10.04 + HibernationDevice: RESUME= + IwConfig: + lo no wireless extensions. + + eth1 no wireless extensions. + + tap0 no wireless extensions. + Lsusb: + Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub + Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub + Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub + Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub + Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub + MachineType: Gigabyte Technology Co., Ltd.
