[Bug 1015369] Re: "IOError: [Errno 32] Broken pipe" on start when many lists are present

[Ryan Finnie]

** Description changed:

  When running "/etc/init.d/mailman start, I get:
  
  # /etc/init.d/mailman stop
-  * Stopping Mailman master qrunner mailmanctl [ OK ] 
- root at chlorine:~# /etc/init.d/mailman start
+  * Stopping Mailman master qrunner mailmanctl [ OK ]
+ # /etc/init.d/mailman start
  Traceback (most recent call last):
-   File "/var/lib/mailman/bin/list_lists", line 122, in <module>
-     main()
-   File "/var/lib/mailman/bin/list_lists", line 114, in main
-     print mlist.internal_name()
+   File "/var/lib/mailman/bin/list_lists", line 122, in <module>
+     main()
+   File "/var/lib/mailman/bin/list_lists", line 114, in main
+     print mlist.internal_name()
  IOError: [Errno 32] Broken pipe
-  * Starting Mailman master qrunner mailmanctl [ OK ] 
+  * Starting Mailman master qrunner mailmanctl [ OK ]
  
  Ultimately the error is harmless since the mailman services start, but
  the problem comes down to:
  
  # /var/lib/mailman/bin/list_lists -b | grep -q "^mailman$"
  Traceback (most recent call last):
-   File "/var/lib/mailman/bin/list_lists", line 122, in <module>
-     main()
-   File "/var/lib/mailman/bin/list_lists", line 114, in main
-     print mlist.internal_name()
+   File "/var/lib/mailman/bin/list_lists", line 122, in <module>
+     main()
+   File "/var/lib/mailman/bin/list_lists", line 114, in main
+     print mlist.internal_name()
  IOError: [Errno 32] Broken pipe
  
  This is on a system with over 600 lists.  grep -q appears to close the
  pipe as soon as it's found a match.  On an install with only a few
  lists, the entire output is within a single buffer page, so this does
  not occur.  But in this case, there is enough output to have other pages
  available when grep closes the pipe.
