Description: ------------ I tried to install PEAR packages on Ubuntu 9.10, but as there PHP comes without zlib (see https://bugs.launchpad.net/ubuntu/+source/php5/+bug/451405), Archive_Tar cannot open the packages. But as the zlib functions are run in silent mode this doesn't throw any errors, making in look like install succeeded. Some error should be thrown if the function cannot be found! Archive_Tar line 658: is the issue here if ($this->_compress_type == 'gz') $this->_file = @gzopen($v_filename, "rb");

The source of the issue was in Ubuntu Karmic (see PEAR #16606 and Ubuntu #451314), but this new PEAR bug highlights the _reason_ for the *silent* failure. This "@" usage should probably be reviewed in light of the silent failure problems.

Archive_Tar does check if the zlib extension is available, and calls PEAR::raiseError() if it isn't.

This bug has been fixed in SVN. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better. Added an additional function_exists() call before gzopen/bzopen to catch this issue should it ever happen again.
