Hello,
Following discussion on python-dev, I plan to untabify the C codebase this afternoon. It would probably be better if nobody modified any C files in the meantime (except those that already use 4 space indents).
I expect the whole operation to take a couple of hours.
Regards
Antoine.

Are you brave, or mad, or both?
Just joking :) No objections from me.

In which case it might be advisable for anyone who doesn't enjoy receiving half-million line emails to turn off python-checkins delivery for a couple of hours...

This was done in r81029 (trunk), r81031 (2.6), r81032 (3.x) and r81033 (3.1). I'm mentioning the revision numbers because it seems python-checkins blocked the diffs, sensibly enough.
There may be a couple of places where formatting was slightly worsened (especially comments). Most of the files look totally fine, though. I've done some visual inspection, but I could not examine each of the 500000 diff lines in each branch.
There was one file that I didn't touch: Modules/_cursesmodule.c Indentation is so uncommon there that interested people should reformat it themselves, if desired.
If you have patches pending and they don't apply cleanly anymore, you can either:
- use "patch -l", and then reformat the modified lines manually
- use "untabify.py -p" on your patch
(http://svn.python.org/view/*checkout*/sandbox/trunk/untabify/untabify.py)
Regards
Antoine.

Does "make patchcheck" detect tab indentation and trailing spaces regressions?

Is it documented somewhere? In the developer FAQ?

No. As a matter of fact, I've never used "make patchcheck" and therefore always forget about its existence. Do you want to propose a patch for this?

I don't think it should go into the developer FAQ, since it's only a temporary situation. IMHO it's sufficient to tell people about it when they ask on the tracker, or even to do the reformatting ourselves.
(I don't think there are many patches pending on the set of modified files, but I could be mistaken)

fwiw, untabify.py seemed to work fine to keep the change I had in my svn client in shape across this update.
svn diff Modules/threadmodule.c >foo.diff svn revert Modules/threadmodule.c svn up # update past the untabify changes ../untabify.py <foo.diff >foo-untabbed.diff patch -p0 <foo-untabbed.diff
Thanks for doing this Antoine (belated +1 from me). It may cause some temporary pain today and while dealing with existing patches on the tracker (anyone want to script walking the tracker and auto-untabifying patches that touch .c/.h files?) but it is worth it for the future health of the code base.

This invocation of GNU indent should work reasonably well:
indent

--indent-level8
--blank-lines-after-procedures
--no-blank-lines-after-declarations
--no-comment-delimiters-on-blank-lines

In Emacs, visit a C file and type:
C-c . python RET
'python' is a standard c-mode indentation style, however it's set up to use tabs. It should be updated, maybe to a 'python3' style? Here's a quick and dirty hack:
(c-add-style "python3" '("python" (indent-tabs-mode . nil) (c-basic-offset . 4) ))

Thanks! I've carried out a re-indentation and whitespace cleanup in the sandbox/curses/ directory; it still compiles & passes its tests, such as they are. Does someone want to take a brief glance at the resulting code to double-check?
http://svn.python.org/view/sandbox/trunk/curses/_cursesmodule.c?revision=810...
I can commit this to trunk. Presumably merging this change to 3.x would fail horribly; for 3.x, should I just carry out the same set of steps (apply some small coding cleanups that could probably be merged from trunk, then re-indent using Emacs)?

Done: revisions 81213, 81214-81216
I used untabify.py + emacs (python3 mode) + manual edit for Py_BEGIN_ALLOW_THREADS / Py_END_ALLOW_THREADS.

"Great or Grand Renamings are often traumatic events for software developer communities ... and complicate the integration of patches created before the renaming but applied after. (This is especially problematic when unrenamed branches exist.)"
Antoine patched the 4 most important branches. Do we you have other active branches?

Any other active feature branches (such as c-decimal and the branch for the signal work) should pick up the tab changes next time they do an svnmerge (or the moral equivalent for Tarek's hg branch).
