Misc/NEWS entries added to released versions
by Matthias Klose 14 Sep '09

14 Sep '09

While looking at the diffs between the 261 release tags and the 26 branch, I noticed many items in Misc/NEWS appearing in the 2.6.1 or even 2.6 sections. I moved all of these to 2.6.2, after checking some of them, and found all of the checked ones be backported after the 2.6.1 release. Is there anything what could be done to avoid these wrong merges? I plan to check the items on the 3.0 branch soon. Matthias

Since we are living in 2009 now, I've changed the encodings of Misc/ACKS and Misc/NEWS to UTF-8 from latin-1. -- Regards, Benjamin

It seems to me (though I admit I haven't been watching closely recently) that the buildbots still report bsddb errors on trunk on a fairly regular basis. If I'm not imagining things is there any chance you could take a look at that? --David

Mysterious uidNNN committers
by A.M. Kuchling 09 Jul '09

09 Jul '09

I've been analyzing how much of the Python code is covered by the contributor agreements in the PSF's possession. The logs show four mysterious IDs of the form uidNNNN; I'd like to figure out who two of those IDs were. (Two of the IDs are gone in 3.1-trunk, so I don't care about them.) uid26747 has one commit that only affected Lib/test/test_generators.py. To me this reads like a Tim Peters commit message. Tim, does this seem familiar? -------------------------------------------------- r21474 | uid26747 | 2001-07-04 18:11:22 -0400 (Wed, 04 Jul 2001) | 11 lines Added a non-recursive implementation of conjoin(), and a Knight's Tour solver. In conjunction, they easily found a tour of a 200x200 board: that's 200**2 == 40,000 levels of backtracking. Explicitly resumable generators allow that to be coded as easily as a recursive solver (easier, actually, because different levels can use level-customized algorithms without pain), but without blowing the stack. Indeed, I've never written an exhaustive Tour solver in any language before that can handle boards so large ("exhaustive" == guaranteed to find a solution if one exists, as opposed to probabilistic heuristic approaches; of course, the age of the universe may be a blip in the time needed!). -------------------------------------------------- uid56795's commit is to Lib/idlelib/Debugger.py. Most of the commits to idlelib around this time are by Kurt Kaiser, but there are a few by Chui Tey. (In either case, both of them have signed agreements, so the code is likely covered.) r27482 | uid56795 | 2002-07-05 18:05:24 -0400 (Fri, 05 Jul 2002) | 5 lines Combine OldStackViewer.py with Debugger.py, removing dead code. M Debugger.py : Incorporate StackViewer, NamespaceViewer classes M StackViewer.py : remove import OldStackViewer U OldStackViewer.py : remove file -------------------------------------------------- uid35364 cleaned up two bare except: clauses in Lib/mhlib.py and rfc822.py. No idea who this was -- IIRC, Skip did a lot of cleanup like this -- but the change is hardly the stuff of intellectual property litigation. r21470 | uid35364 | 2001-07-04 03:01:29 -0400 (Wed, 04 Jul 2001) | 3 lines Clean up a bare except: clause. r21471 | uid35364 | 2001-07-04 03:07:33 -0400 (Wed, 04 Jul 2001) | 3 lines Clean up a bare except: clause. -------------------------------------------------- uid28957's one commit is a regex tweak. The mention of an SF bug lets me identify this as probably by Sjoerd Mullender. r21472 | uid28957 | 2001-07-04 06:15:58 -0400 (Wed, 04 Jul 2001) | 5 lines Fix for SF bug #425868. We should not depend on two spaces between words, so use the white space after the to-be-encoded word only as lookahead and don't actually consume it in the regular expression. -------------------------------------------------- --amk

I think this should be reverted -- the support code is not for the bsddb module, but for building the dbm module with bsddb.

Why r69846 is not merged to "release26-maint"?
by Jesus Cea 05 Jul '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have found a few flaws in 2.6 documentation. I was going to correct them when I found they are already solved in trunk in r69846, done by mark.dickinson in february. Is there any reason for that commit not to be merged to 2.6 branch?.
