Re: [Twisted-Python] porting twisted.spread to Python3

2014-11-03 Thread Wolfgang Rohdewald
there now is https://github.com/wrohdewald/twisted.git

branch spread-py3-7598

Not all is finished, especially utf-8 wherever Python 3
allows it, pbfailure, and handling of wired exceptions.


what should I do next to start getting this into trunk? 
Maybe

- open a ticket for porting banana
- create a branch with all commits for that
- do a pull request

I do not want to create one big patch because I think
it is helpful to have more smaller commits.


But I probably should wait with all that until 
ticket 7664 is merged.

[Twisted-Python] The Path to Twisted 14.1

2014-11-03 Thread HawkOwl
Hi everyone,

To keep everyone in the loop...

Since 14.0 came out months ago, and we really should have 14.1, I think it’s 
time we bit the bullet and cleaned out the regressions to get it out the door. 
Unfortunately, all of the currently open regressions are from the new logging 
system (#6750, plus #7548 and #7545) Since these regressions are introduced by 
a new ticket, we should revert them, and get the regressions fixed before it is 
remerged. I’ll make a new milestone called “New Twisted Logging” or similar so 
that they’re all still kept track of as a group.

The only other big thing preventing 14.1 is 
https://twistedmatrix.com/trac/ticket/7647 , the patch that 14.0.1/14.0.2 was 
released to include. The patch fixes it, but not ideally, so it needs looking 
at.

Once I’ve reverted those tickets and we can get #7647 refined and merged in 
some form, 14.1 will be out the door :)

Yep, this is right.  Creating a patch and attaching it to the ticket would also 
be useful.

 - do a pull request

Opening a pull request is not a particularly useful part of this workflow :-).  
The ticket is sufficient.  See https://github.com/twisted/twisted/pull/46 or 
any pull request closed recently for more information.

 I do not want to create one big patch because I think
 it is helpful to have more smaller commits.


 But I probably should wait with all that until ticket 7664 is merged.

I should note that this is already in review.  Anyone want to have a look?

I have mixed feelings about this plan.

On the one hand, this is technically the way the policy works: if there's a 
regression that hasn't been in a release, it's supposed to be reverted.

On the other hand, this is not the way the policy has been enforced in the 
past.  Particularly, we've rarely done reverts where we had to revert multiple 
changes which depended upon each other, where regression fixes had already been 
accepted onto trunk and multiple outstanding branches which had already been 
through review were pending.  It would be nice if we could just get the 
regression fixes landed.

On the gripping hand, many of these regressions have been outstanding for 
months, and so if we could get these fixed promptly enough, presumably we would 
have done that already.

In favor again of reverting is the fact that no code outside 
twisted.python.logger or twisted.python.log has been modified to take advantage 
of the new system, so we're not going to be breaking any dependencies on trunk.

My biggest concern is that this feature was big enough that it dang near broke 
the review process the first time.  Clearly code review wasn't sufficient to 
spot these regressions in the first place.  There's no reason to believe that 
anything but code that lives on trunk for a while is going to flush out these 
more complex interactions.

Delaying the revert is likely to just make things more painful.  Tempting as it 
is to suggest, bitter experience has taught me that trying to cram things into 
a release is a recipe for sadness.  So rather than asking if you could hold 
off, could I instead make two requests for this feature:

Can please we do reviews of the fixes to the regressions as if they were 
landing on trunk, and not have this revert re-open the need to review the 
entire (rather large) change?
If we can manage to get this feature landed again quickly after 14.1, will you 
have time to do a fast-following 14.2?
