A month ago, for 3.5 and 3.6, I added a test file by Westley Martínez (note accent on i) and then his name intoMisc/NEWS and idlelib/NEWS.txt.  As a result, the latter will not display when the button on About IDLE is clicked.  Instead, a UnicodeDecodeError is sent to stderr.  I will add a test for the About box.

Larry, there is a slight reversion in 3.5.2rc that I think should be fixed: idlelib/NEWS.txt will not display from About IDLE dialog because it had a couple of non-ascii chars.  idle_news-35.diff has the full patch.  A minimal fix for 3.5.2 final would consist of changing 'ascii' to 'utf-8' in idlelib/aboutDialog.py and the recoding the 2 characters in NEWS.  Testing changes in the other 2 files could wait. Since I don't know how you want to do this now, I have not pushed anything yet.

If the diff is literally changing two lines, I'll accept it.  Guido relaxed the rules for IDLE changes.  If it breaks something it's on *your* head ;-)Please just check it in normally.  Either I'm going to use hg to cherry-pick the changes for 3.5.2 final, or I'm going to have to apply patches manually anyway.  Either way an hg checkin is fine.Please check in this minimal change *as a separate checkin* from the larger changes, if you're committing the other changes any time soon.

I should mention that I have separate 3.5 and 3.6 patches because I know that the merge will not work.

I was wondering if splitting the patch would be better.  Shelve makes it easy.

783dfd77e4c1 is the one to pick for 3.5, then null merge if you merge to 3.6.

Because of the case conflict I did not notice soon enough, the rest of the patch and merge did not go well and I got thistest test_idle crashed -- Traceback (most recent call last):  File "F:\Python\dev\36\lib\test\libregrtest\runtest.py", line 180, in runtest_inner    test_runner()  File "F:\Python\dev\36\lib\test\libregrtest\runtest.py", line 178, in test_runner    raise Exception("errors while loading tests")Exception: errors while loading testsI suspect it is a problem with textView/textview, so I will temporarily disable test files to find the culprit.

Suspicion wrong.  idle_test and hand tests pass.Larry, I am done with this.  I left it open until you are also.

Is this dance with renaming forever?

No, it ends with the last 3.5 maintenance release in about 6 months.  When I did it right, as in#27245, which was otherwise a clean single file merge, there was no problem and it took at most an extra 30 seconds.  I know what I did wrong this time, starting with not writing down the steps needed, and in which order, for a much more complicated merge.

You speak confidently, for a guy who hasn't seen any sort of schedule from the 3.5 RM.  :-OAfter 3.6 comes out, I expect 3.5 to get one more "bug fix" release.  And *then* it will transition to "security fixes only" mode.  Six months is the absolute minimum, and I'd expect it to be longer than that.

As a practical matter, I have no plans to backport except in exceptional cases.  If the regression had only affected 3.6, I would have left 2.7 and 3.5 alone.

If this is fixed, and resolved, why is it still open?  Closing.
