Subject: dselect crashes

Date: 19 May 1998 23:24:00 +0300

Package: dpkg
Version: 1.4.0.22


I have collection of Debian 2.0 packages.  Downloaded mainly 5.5.98.
Some packages later, so I use 'scan' instead of Packages file.  I
started with clean partitions, because i wanted to protect old working
Debian.

Selection of packages is normal, but installation ends:
"internal error - no filename at -e line 12, <P> chunk 13.

 installation script returned error exit status 1.
 Press RETURN to continue."

Sometimes if i enter selection after this dselect crashes
(segmentation fault, core dump).  Twice this created invisible file(s)
of few MB.  Only trace of that file(s) is that outputs of df and du
don't match.

Only 'e2fsck -f' frees that disk space.

I tested with kernel from rescue disk and also 2.0.33 kernel i have
compiled earlier.  I have no hardware problems with old Debian
installation.  (486 DX2, 32 MB ram)

I guess some installation script crashes.  Dselect does not report
witch package is broken, not even with -D.  How do i found witch one?

Or at least i don't find this useful:
getcurrentopt() cmethopt open
getcurrentopt() cmethopt eof
getcurrentopt() cmethopt read
getcurrentopt() cmethopt len and newline
getcurrentopt() cmethopt space
getcurrentopt() cmethopt meth name `disk'
getcurrentopt() cmethopt meth found; opt `mounted'
getcurrentopt() cmethopt opt found


I tried to found it by selecting only few packages, but that failed.
Perhaps order in witch packages are installed is important.

I think this is also dselect bug, because it should report, at least
with -D, what it is going to try next.

I can test this more if someone replies soon.

What immediately preceeds these messages ?

Are any processes left running ?

I am still very suspicious of your hardware.  The unlinked file seems
particularly difficult, if dselect and its children have all exited.
Did you do a ps ?

I have not had any other reports offd dselect coredumping.

Probably -D should arrange for the method scripts to set `set -x'.

I have got only one reply (from Ian).  In case my reply to Ian
disappeared i'll answer again:

> What immediately preceeds these messages ?

New test:
- I reboot to debian 2.0 (root = hda2,  hda1 is debian 1.3 root)
- dselect
- i select install from menu and press enter
- i watch blank screen few seconds
internal error - no filename at -e line 12, <P> chunk 16.

installation script returned error exit status 1.
Press RETURN to continue.

- last lines of debug.log:
getcurrentopt() cmethopt open
getcurrentopt() cmethopt eof
getcurrentopt() cmethopt read
getcurrentopt() cmethopt len and newline
getcurrentopt() cmethopt space
getcurrentopt() cmethopt meth name `disk'
getcurrentopt() cmethopt meth found; opt `mounted'
getcurrentopt() cmethopt opt found

- i press RETURN to continue
- i selected select from menu. This time it worked normally.
- i select install from menu and press enter (again) 
- i watch blank screen few seconds
internal error - no filename at -e line 12, <P> chunk 16.

installation script returned error exit status 1.
Press RETURN to continue.
- i selected select from menu. (again) 
Segmentation fault (core dumped)

- no file system damage this time.

Didn't check that, but e2fsck -f did found something to fix (not after
every test, but twice).  I had to use -f, because file system was
'clean'.  No file system errors in /usr, /var and /home.  Everything
else is in hda2 (root).  Only big related files in /root are core and
debug.log.  (This could be kernel/c-lib bug.)

Sorry i didn't.  486 DX2 66, 32 MB REAL parity simm (has to be parity
simm for this mother).  I have tested over-clocking to DX2 80 with
same bios settings.  No errors in kernel compilation even then (20 %
less cpu time).  Unfortunately 40 MHz VLB bus speed is too much for
display controller (x-bug?).  So i'm using 66 MHz cpu clock.

I recompiled kernel.  No errors. I don't think i have hardware problem
(now:)

Related bugs (same?):

#18028: scanning package dir breaks install  
(92 days old.)

#17897: dpkg: dselect core dumped
( 95 days old. )

#17915: dselect seg faults
( 95 days old. ) 

#11631: dselect: internal error - no file name at -e line 12, <P> chunk 16.
( 286 days old. )

I should have checked those before posting my own, but i did only check 
developers' mailing list and did not look for so old messages:)

I compared my 'available' file with 'packages' file and 'available'
seems to be OK.  I don't have any broken links.  Almost all packages
have correct md5sums.  There are few i cannot test (138 packages are
newer or older than my md5sums file).

I did more testing:

 dselect install crashed, but dpkg -iGROEB did install packages without
major problems.  I selected more packages and dselect crashed when
trying to install.  Again dpkg -iGROEB installed everything.  Dselect
does not crash anymore, so i can't test this easily now.  

I tried earlier to find package causing dselect to crash, but failed.
Dselect crashed when starting to install small group of packages, but
installed those OK when selected one by one.

I haven't seen my bug reports on debian-devel@lists.debian.org.

Subject: these bugs have all been fixed in the latest dpkg (1.6.9)

Date: Mon, 6 Mar 2000 18:25:13 +0100

Hi people,

These bugs you have reported have all been fixed in the latest dpkg
package, version 1.6.9.

     * #1399: dselect error handling not consistent
     * #6007: dselect pbm.

Dselect now displays a message saying that the database is inaccessible or
that it is locked, asks for <enter>, and returns to the main menu
afterwards.

     * #13187: --quiet|--verbose on update-alternatives don't do
       anything.

Verbosity ($verbosemode) has been implemented in update-alternatives.

     * #17877: dpkg: 'help' gets annoying after a while

There is a `--expert' command line option for dselect that turns off
automatic help messages.

     * #17897: dpkg: dselect core dumped
     * #18028: scanning package dir breaks install
     * #18484: dpkg: "internal error" in dselect
     * #18540: dpkg: unhelpful error message (invalid control file)
     * #22649: dselect crashes

This was an old bug in the "disk" access method, and it seems to have been
fixed long ago.

     * #21330: dpkg: link and use problems on non-snprintf platform

The snprintf usage in that file was fixed.

     * #46747: dpkg: [hurd] start-stop-daemon

This Hurd patch was applied.

     * #52919: dpkg: Dselect main menu title line incorrect (has %s,
       printf problem?).

This %s was fixed.

(Wichert, dpkg maintainer, has told me I may close these bug reports instead
of him)

Thanks for reporting.
