I am running on drupal 6.4 with drush ..... well, not sure. below is the .info file....

name = Drush
description = "drush (the drupal shell) provides a command line interface for Drupal."

The problem I am having is that drush will update itself into a state where it no longer works and throws all kind of php errors. What i want to know is if it is possible to have drush skip itself in the update process. drush has worked perfectly until just a few days ago. using svn i have restored the drush scripts to a state where they work and i want to keep it there at that rev and not progress. im not sure if this is an issue or not but i wasn't sure where to ask.
#1
That version is very old and has a few known bugs - could you please delete the old version (together with any drush_extras you might have installed) and try http://drupal.org/node/435004 instead?
#2
First of all, im am surprised and impressed at the speed i got a response.
but when i use that version i get the following error message....
PHP Notice: Undefined variable: options in /var/www/htdocs/employee/sites/all/modules/drush/includes/command.inc on line 71

The command 'drush.php pm update' could not be executed. [error]
and i didn't get any of that before updating the code.
----------------------------------
edit: the OS is centOS 5 is that helps or make any difference. I get the same error messages as above when using Ubuntu 8.04 server AMD 64
----------------------------------
edit (again): disabling the badBehavior module gets rid of the errors from that module so those are in no way related to the problem i am having
#3
after messing around with arguments, i have more to tell....
this is what i get with the verbose option on pm update

allright, i fixed it.
here was the problem for future reference. I was running a version of php that was older than 5.2.0. pre 5.2.0 doesn't have the json_encode() and json_decode() which this module relies upon. depending on your version of your OS, you can apt-get update php or yum update php or up2date php but some you have to install the jason module by hand. google for your individual OS and find out how to do it.
issue can be closed. thanks :)

@dmjossel - drush update runs drush updatedb as a separate process call - it looks like that call is not finding your php 5.2+ version for some reason, but is finding an older version instead (http://us.php.net/json_encode - was introduced in 5.2). I would suggest checking into what php version is being found by that process and why.
#8
Having also been bitten by this just now, with PHP 5.2.10 on FreeBSD, it's worth noting that json commands might have been introduced in 5.2, but they are part of an extension. You need to be sure you install/enable that extension (or add the right part to your ./configure incantation if you compile from source) to get the json_* commands, even on 5.2+
The FreeBSD Port is called php5-json, for example.
#9
A simple check could be added at the top of drush.php after php version check:
if (!extension_loaded("json")) {die("Your PHP installation does not include json extension. Drush requires this extension to run some commands.\n");
}
It seems hard to me add this check on each command that will use
drush_invoke_backend.#10
Thanks AnotherHowie #8 did the trick.
