[2.5] Plugin update and temporary directories

  • I’ve tried to use the automatic plugin update script, but ran into some trouble which might be worth looking into.

    I’m using a setup where the standard system temp dir ( for some reasons ) isn’t writable, so you get error like these:

    Warning: tempnam() [function.tempnam]: open_basedir restriction in effect. File(/var/tmp/) is not within the allowed path(s): (/home/bla:/home/bla/public_html/include) in /home/bla/public_html/wp25/wp-admin/includes/file.php on line 321

    For that I’ve set the WP_TEMP_DIR constant to a writable map. This takes me one step further to where the download is tried to be saved. Due to the $wp_filesystem _ $method this one is handled by the FTP class in wp-admin/includes. This one uses a different constant name FTP_BASE ( is that correct? ). Otherwise this step won’t work.

    it both generates the error: ‘Unable to locate WordPress directory.’, but the error is generated firstly on file.php and in the second case on class-wp-filesystem-ftpext.php

    The problem is when both are set the whole function (download goes correct – I checked ) stop when for some reason it cannot extract the zip file ( unable to copy zip-file ).

    I cannot see why not, the zip-file is there. Both constants point to the same map and yet the function keeps on looking for /var/tmp as the map to go, while it uses get_tmp_dir() to get a temp location in any way. Both are outputting that correctly.

    This perhaps might be something you want to document as well as probably more people will have problems with it ??

  • I have same problem whit my WordPress blog (version is 2.5.1):

    Warning: tempnam() [function.tempnam]: open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (/home/e1:/usr/lib/php5:/usr/share/php5:/usr/share/php:/var/www/htdocs:/var/www/localhost/htdocs) in /home/e1/public/www/wp-admin/includes/file.php on line 322

    when I write to the wp-config.php file:

    define('WP_TEMP_DIR', ini_get('upload_tmp_dir'));

    WP generate error:

    Warning: ftp_pwd() [function.ftp-pwd]: Directory successfully changed. in /home/e1/public/www/wp-admin/includes/class-wp-filesystem-ftpext.php on line 188

    Warning: ftp_pwd() [function.ftp-pwd]: Here comes the directory listing. in /home/e1/public/www/wp-admin/includes/class-wp-filesystem-ftpext.php on line 188

    The WP directory is: /home/e1/public/www
    The temp dirctory is: /home/e1/tmp

    After all kinds of testing I found out, that the updater doesn’t work with “paranoid” firewall settigs combined with not passive ftp mode!

    The solution is to allow passive ftp mode on the server.

    I am also facing a similar issue:
    After some ‘tmp dir not writable’ errors, I have pointed WP_TEMP_DIR to the correct directory, but now another error is remaining:

    Warning: ftp_rawlist() [function.ftp-rawlist]: Unable to create temporary file. Check permissions in temporary files directory. in /is/htdocs/wp1008945_0Q245FN7MJ/wordpress/wp-admin/includes/class-wp-filesystem-ftpext.php on line 192

    Unable to locate WordPress Plugin directory.

    Installation Failed

    Any idea?

    i was also affected by the safe mode restrictions

    fixed it by the following:

    added to /config.php

    define('WP_TEMP_DIR', '/my/writable/dir');

    removed trailingslashit() from /wp-admin/includes/file.php
    line 75
    now looks like this:

    function get_temp_dir() {
	if ( defined('WP_TEMP_DIR') )
		return $WP_TEMP_DIR;

    maybe code needs to be fixed there in the next update

    Add this in your wp-config.php

    define(‘WP_TEMP_DIR’, ini_get(‘upload_tmp_dir’));

    in php.ini add the path to allowed(with permissions) temp dir
