Subject: php5-symfony1.0: postinst script hangs

Date: Mon, 15 Dec 2008 18:47:12 +0100

Package: php5-symfony1.0
Version: 1.0.19-1
Severity: grave


Hi,

when I try to upgrade this package, here is what happens:

Setting up php5-symfony1.0 (1.0.19-1) ...
[hangs indefinitely]

The hung process is this one:

# ps aux | grep /usr/bin/php
root     16898  0.0  1.6  67712 17112 pts/1    S+   18:31   0:00 /usr/bin/php -C -q -d include_path=/usr/share/php -d output_buffering=

re/php/pearcmd.php config-get data_dir

and according to strace it hangs on this syscall:

# strace -p 16898
Process 16898 attached - interrupt to quit
futex(0xb470aea0, FUTEX_WAIT_PRIVATE, 2, NULL

Can you confirm the version of php5-cli installed, and can you also do the following

gdb
attach <pid>
bt full


and send the backtrace? (so I can find out where this comes from)

also, what version of libmysqlclient15off have you got installed?

I see you're running mixed/experimental -

You may need to install php5-dbg for this to be meaningful

ii  libmysqlclient15off                                      5.1.19beta-1                           mysql database client library

The rest of my mysql installation is version 5.1.30-2.

Downgrading this package to version 5.0.67-2 fixes the problem.

Since libmysqlclient15off version 5.1.19beta-1 no longer exists, this
bug is moot.  It would be interesting to see what happens with a PHP
linked with libmysqlclient16...  How about retitling this bug and
transforming it into a wishlist report to have an experimental PHP
version ?

thanks

I'm afraid you'll have to create a new bug for that, closing this now as
issue addressed.
