pear install fails without error message, downloaded go-pear is also affected (Karmic)

[Gabor Halaszvari]

Binary package hint: php5

After the workarounds applied from #420639 (cleaning and updating channels), "pear install" downloads the packages but exits without any error message just before the installation (or unpacking) starts.

I removed the php-pear package and tried to install pear via go-pear (downloaded from http://pear.php.net/go-pear).
This type of installation exits also when the installer unpacks the package PEAR.

I confirm this bug on a fresh Ubuntu Server 9.10-beta
ex :
root@ubuntu:~# pear install Crypt_CHAP
downloading Crypt_CHAP-1.0.2.tgz ...
Starting to download Crypt_CHAP-1.0.2.tgz (5,494 bytes)
.....done: 5,494 bytes
root@ubuntu:~#

I try pear upgrade but there is the same problem :
root@ubuntu:~# pear upgrade
downloading PEAR-1.9.0.tgz ...
Starting to download PEAR-1.9.0.tgz (291,634 bytes)
.........................................done: 291,634 bytes
root@ubuntu:~#

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:
1. Is this reproducible?
2. If so, what specific steps should we take to recreate this bug? Be as detailed as possible.
This will help us to find and resolve the problem.

1. Is this reproducible?
Absolutely. It happens at every "pear install" and "pear upgrade" command.

2. If so, what specific steps should we take to recreate this bug? Be as detailed as possible.
Try to upgrade a pear package, or try to install a new one. The package will be downloaded, but pear is exiting before the installation without any error message:

Examples:
  root@nx7400:/root# pear install Date
  downloading Date-1.4.7.tgz ...
  Starting to download Date-1.4.7.tgz (55,754 bytes)
  .............done: 55,754 bytes
  root@nx7400:/root#

  root@nx7400:/root# pear upgrade-all
  Will upgrade channel://pear.php.net/pear
  downloading PEAR-1.9.0.tgz ...
  Starting to download PEAR-1.9.0.tgz (291,634 bytes)
  .................................done: 291,634 bytes
  root@nx7400:/root#

  root@nx7400:/root# pear install Pear
  downloading PEAR-1.9.0.tgz ...
  Starting to download PEAR-1.9.0.tgz (291,634 bytes)
  .............................................................done: 291,634 bytes
  root@nx7400:/root#

The output of the same command under Ubuntu 9.04:
  root@pcdev01:~# pear install Date
  downloading Date-1.4.7.tgz ...
  Starting to download Date-1.4.7.tgz (55,754 bytes)
  .............done: 55,754 bytes
  install ok: channel://pear.php.net/Date-1.4.7
  root@pcdev01:~#

The last line of the 9.04 output (install ok: ....) shows that the downloaded package was successfully unpacked and installed.

The pear script in 9.10 exits before this step (the downloaded 'go-pear' script also).
I think it's related to the PHP zlib extension and the Archive_Tar pear package which is used to unpack the downloaded files.

pear install work with -Z option :

root@ubuntu:~# pear install -Z Auth_SASL
downloading Auth_SASL-1.0.3.tar ...
Starting to download Auth_SASL-1.0.3.tar (Unknown size)
............done: 44,544 bytes
install ok: channel://pear.php.net/Auth_SASL-1.0.3
root@ubuntu:~#

Thank you!

This workaround is working.

The "pear help options" says nothing about this command line option. Is this an undocumented one?

Maybe it's related to the zlib bug mentioned here also: http://www.nabble.com/Re%3A-Debugging-pear-install-hang-p25037632.html

Also, in the future, please try pear install -vvvvv Foo. Might give you more info.

[Gabor Halaszvari (g-halaszvari)]

This is the output running with the -vvvvv option:

root@nx7400:/home/halaszvarig# pear -vvvvv upgrade Structures_Graph

-vvvvv gives me no output!
But the -Z workaround worked perfectly!
