Description Stephane Peter 2004-06-17 19:51:17 EDT
Description of problem:

Printconf chokes when it encounters any queue name that starts with a
number. While it is not possible to create such queues through
printtool directly, this can happen if the user does it through the
CUPS interface, or through a third-party program.

Version-Release number of selected component (if applicable):

Has been happening since at least Redhat 9.

How reproducible:
Consistent

Steps to Reproduce:
1. Create a queue with a name that starts with a digit (like
123printer), through the CUPS web interface.
2. Run printtool
3. Witness the stack dump.
  
Actual results:

printtool is unusable until the queue is removed manually.

Expected results:

No crash should occur. It is also unnecessary to restrict the queue
names this way, as numeric queue names are perfectly well supported by
both CUPS and LPRng.

Here is a typical Python stack dump :

Traceback (most recent call last):
  File "/usr/sbin/printconf", line 9, in ?
    import queueTree
  File "/usr/share/printconf/util/queueTree.py", line 1235, in ?
    queueTree()
  File "/usr/share/printconf/util/queueTree.py", line 140, in __init__
    cups_import.import_cups_queues ()
  File "/usr/share/printconf/util/cups_import.py", line 183, in
import_cups_queues
    line[i][1] == "D")
  File "/usr/share/printconf/util/cups_import.py", line 132, in
_discover_queue
    construct_queue (type_space, data_dict, driver_tuple)
  File "/usr/share/printconf/util/printconf_conf.py", line 879, in
construct_queue
    queue =
queue_edit.dynamic_queue_ctx.data["/printconf/print_queues"].addData(AdmListType,
queue_name)
ValueError: "105brightq" is an invalid name.

This is an alchemist limitation.

Worked around in Fedora development.
