Re: [expert] Syncing Handspring Visor Deluxe?!

The steps below assume you've got jpilot configured to talk to the correct device (/dev/ttyUSB1 in my case, though /dev/usb/ttyUSB1 should be the same), the device has the correct permissions, etc. 1. Manually remove the usbserial and visor modules if they're loaded: rmmod visor rmmod usbserial 2. Start a local sync on the Visor. 3. 'tail -f /var/log messages' and wait until you see something like this message come out (make take 10 seconds): Feb 11 10:32:10 x kernel: usbserial.c: Handspring Visor / Palm 4.0 / Clii 4.x converter now attached to ttyUSB1 (or usb/tts/1 for devfs) 4. Start jpilot and press the Sync button. 5. If jpilot seems to hang, close it, cancel the sync on the Visor, and go to step 1. It's pretty annoying but I'm too lazy to debug the pilot-link library to try to figure out if it's the cause, or if it's a driver problem. Want to buy your Pack or Services from MandrakeSoft?

The fix was to fetch a totally stock 2.4.20 kernel from kernel.org and build a custom one for myself. The important change I made in the configuration versus Mandrake's was to enable CONFIG_APM_ALLOW_INTS. I believe that is necessary for IBM laptops, but I could be wrong.

The script brings down eth0 before the tweaking the symlinks (ifdown eth0) and brings it back up again afterwards (ifup eth0). It also restarts postfix after tweaking main.cf (postfix reload); otherwise postfix will refuse to send mail if it's moved from one network to another. MacOS has a feature called location manager that does this sort of thing with a GUI. I think it would be very useful on Linux, too. Want to buy your Pack or Services from MandrakeSoft?

[expert] USB 6-in-1 card reader solutions
On a whim I bought a cheap 6-in-1 USB flash card reader (the maker's web site is www.pqiusa.com). I managed to get it to work on my Mandrake 9.0 laptop, but it was a bit tricky. The first problem is that that 2.4.19 kernel in 9.0 doesn't seem to recognize that this device is actually four different devices, one for each of the card slots (the 6-in-1 is a slight exaggeration; a couple of the card types share slots). On my parents' totally stock 9.0 desktop machine, only the first card slot was configured automatically as device sda; the rest were ignored. I didn't have time to find a fix for this. I didn't have this problem on my laptop running 9.0, perhaps because I'm using the 2.4.20 kernel from kernel.org, with devfs disabled. There may have been some changes in the usb storage drivers, but I didn't track them down. I'm just happy the thing works. In /var/log/messages I can see each of the four devices being configured as sda through sdd. The second problem is that the ide-storage module isn't getting removed when the device is unplugged. So if the device is plugged in again, it gets treated as a new SCSI host (scsi1) instead of scsi0, and the four slots get configured as devices sde through sdh. The only workaround I could find was to 'rmmod usb-storage' after unplugging the device. To do this automatically, I made the following ugly hack to /etc/hotplug/usb.agent: *** usb.agent.orig 2002-04-01 13:51:32.0 -0800 --- usb.agent 2003-01-12 18:00:18.0 -0800 *** *** 323,328 --- 323,331 esac if [ $DRIVERS != ]; then FOUND=true + echo #!/bin/sh $REMOVER + echo rmmod $DRIVERS $REMOVER + chmod +x $REMOVER fi # cope with special driver module configurations Want to buy your Pack or Services from MandrakeSoft?

I didn't try to find one with Mandrake patches, though I believe a 2.4.20 cooker kernel is available now, according to messages that came through earlier on this mailing list. P.S. I had to go with a non-Mandrake kernel because Mandrake's kernel crashes on suspend/resume cycles on my Thinkpad A21m (the kernel in MDK 8.1 worked fine). I believe this is because Mandrake disables CONFIG_APM_ALLOW_INTS in their configuration, or something big has changed in the APM support since 8.1, or both. So even a cooker 2.4.20 kernel would probably not work for me. Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

[expert] GDB and threads - fixed
GDB can't debug apps that use threads (libpthread.so) on Mandrake 9.0.
There are two reasons for this, both caused by Mandrake's broken
installation of glibc. I finally got these problems fixed on my
system, with lots of help from a co-worker and day of debugging GDB
with itself.
1. The first problem was that the shared library libpthread.so had its
symbols stripped by Mandrake. The symptom is that GDB complains about
a weird signals (SIG32, to be exact) when debugging a program that
uses pthreads.
The fix was to install the glibc source RPM, rebuild it ('rpm -bc
glibc.spec'), and copy the non-stripped i686-specific libpthread
shared library to /lib/i686. If you are in the build directory
/usr/src/RPM/BUILD/glibc-2.2.5, then copy the file as follows:
cp build-i686-linux2.4/linuxthreads/libpthread.so /lib/i686/libpthread-0.9.so
After this, run 'ldconfig -v' just to be sure the new library gets
used, but it's probably not necessary.
NOTE: yes, there really are two libpthread shared libraries, one in
/lib (generic), and one in /lib/i686 (Intel 686-specific). There
are important differences between the two, such as the sizes of
certain thread data structures and the presence of certain functions.
The data structure size mismatch turned out to the source of problem 2
below. I suspect the generic library in /lib should not even have been
installed by Mandrake, since it's not used by apps that are linked
with -lpthread.
The more permanent fix, which Mandrake should be using, would be to
edit the spec file (glibc.spec), and adding libpthread to the list of
libraries to NOT strip:
EXCLUDE_FROM_STRIP=ld-%{glibcversion}.so libpthread-0.9.so
The exact spelling of the library filename must be given as shown.
Then the binary RPM can be built (I haven't tried this myself yet).
2. Once that problem was fixed, GDB would now crash with a segfault
debugging pthread apps. This turned out to be due to the data
structure size mismatch mentioned above. GDB was using the generic
libthread_db.so (the thread debugging librrary) in /lib, which had a
different idea of the size of the _pthread_descr_struct structure than
the app being debugged, which used the processor-specific pthread
library in /lib/i686.
I chose to fix this by copying the i686-specific libthread_db.so to
/lib/i686. If you are in the build directory
/usr/src/RPM/BUILD/glibc-2.2.5, then copy the file as follows:
cp build-i686-linux2.4/linuxthreads_db/libthread_db.so \
/lib/i686/libthread_db-1.0.so
Then move to the directory /lib/i686 and create the following symbolic
link:
ln -s libthread_db-1.0.so libthread_db.so.1
Finally, run 'ldconfig -v' to make sure this library gets put in front
of the bad one in /lib.
I'm not sure what permanent fix Mandrake should be using. Either the
spec file or one of the Makefiles should be edited to copy the thread
debugging library to the correct directory; I haven't looked into this
yet.
