[patch] add more lists to class Ticket, delete unneeded whitespace

[hoff.st@…]

on code review for another enhancement I recognized lists being constructed multiple times in trac/ticket/model.py, probably grown so for historical reasons

first attached patch adds to class Ticket

• self.std_fields
• self.custom_fields

changes occurrences of *_fields to self.*_fields accordingly and deletes all obsoleted statements for re-construction of said lists.
I did it, because I plan to use ticket.custom_fields in trac/ticket/web_ui.py too.

second attached patch just deletes some occurrences of obsolete, unneeded whitespace, if you care

seems the first patch needs some fixing, Exception raised when testing, suggests that 'resolution' key in std_fields is not present in dict values when creating new ticket, so seems like I've found one of the reasons for the re-assembling of this list

wouldn't it be best to just set the missing key like

values['resolution'] = ''

than to work around another way?

undoing deletion of private list std_fields in do_insert() inside (Ticket.)insert() fixes this, going on with some more test, to be sure

Sorry for the delay. After more testing I recommend going on with fixed version added above, so look at both *.2.patch now. For more comments on this I recommend reviewing my corresponding notes in ​http://bitbucket.org/hasienda/custom-time/src/tip/series, since this is part of a bigger effort. Thanks for taking care.

Both patches look fine.

List comprehensions are good, but in this specific case as you need 3 of them (self.std_fields = [f['name'] for f in self.fields ...) maybe it would be a bit more efficient and clearer to expand those 3 in one single for loop iteration.

Actually, the logic you requested was already there some lines below. I merged best of both loops to shorten some statements a little and make variable fname obsolete. This is version 3 of both patches now. Thanks for the encouragement to improve this.
