I see no reason to *not* add a ChangeLog entry here. Please, consider
the fact that some people don't want to go digging in cvs log to see who
added -fno-strict-aliasing or why. (as an example. I, personally, don't
care about -fno-strict-aliasing)

Apart from whether or not this is true, do I understand well that you
consider masqueraded EAPI bumps as homepage updates as trivial changes
too? (traitsbackendwx)

If a change in EAPI doesn't require any other changes in ebuild, then it's a trivial change.

Your definitions of trivial are getting more and more convenient with
each commit.

Trivial is when you fix spelling in text sent to stdout/stderr or
change the text of a comment. Any change to code, including variables,
is not trivial and should be documented in the ChangeLog.

A "trivial" change is fixing a typo, or a manifest problem, a missing
quotation mark, etc. Anything else is not "trivial".

Anything that changes how an ebuild functions, what it does, or the
installed files (and/or their contents) is NOT a trivial change.

Why argue about this? Just always add a ChangeLog entry, like everyone
else. This is in everyone's interest, including yours.

This adds a cflag preventing the compiler to make some assumptions on the code 
for its optimisations, hence making the code slower/bigger. While the 
changelog entry will help figuring out why this was added, a comment in the 
ebuild explaining why will be even better.
Once you'll have to dig into 4 years of cvs log to figure out wth a cflag 
filtering/addition was added into an ebuild maybe you'll reconsider your 
opinion.

Please always keep in mind that you're not the only one that will ever commit 
to $package and even less the only one that will have a look at a given 
ebuild.

mucking with CFLAGS without documentation is wrong.  compiler warnings come 
and go, so a flag that was relevant one day could be completely extraneous the 
next.

however, especially with strict aliasing, you arent "just fixing warnings", 
you're changing optimization behavior of gcc to workaround broken C code.  
this obviously does not fall anywhere near the "trivial" mark.

i see you still havent fixed this, so get on it already.  a bug needs to be 
opened somewhere to get the package properly *fixed*, and your change either 
out right reverted or add a comment around the flag to indicate the open bug 
on the issue.

This problem is probably caused by bugs in Python 2, which have been fixed in Python 3.

Actually this makes me question the append-flag even more.
Why mess with what gcc does with the code for all versions of python if
it works for x version of python?
And "only" for som warnings? I could have understand a bit more if it
was Errors.

Also why not even a comment saying?

Currently as one of the users of hardened and helping Zorry out with the
hardened toolchain I have seen many packages filter flags like -fPIE and
-fstack-protector without a comment on why, where and how it broke, and
noone remeber why.
New versions comes of software and if you do not know why it broke with
a cflag you cannot test if the breakage is still there.

This line of code is fine and all that until you forget why you added
that flag or you retire and a later maintainer of the package does not
dare to touch the flag since they do not know why it was added and what
will break if the remove that line of ebuild code.

the new information you've provided here only reinforces the fact the current 
code is wrong.  properly document the append-flags and properly restrict it to 
when python-2 is being used.

considering python-2 is going to be in our lives for a while, how hard is it 
to backport the changes in question to the headers ?  presumably it's 
struct/union/cast shuffling in the headers.

This is upstream python bug 969718 offhand; basically if cflags exists 
for distutils consumers, base cflags don't make it fully through- 
meaning no -fno-strict-aliasing as is generally needed for building 
python extensions.

As for py3k, looks of it py3.1 still suffers it.


Either way, this is the wrong thing to fix- python's distutils 
needs fixing, not consumers.  In snakeoil, we detect and fix it on the 
fly to provide a fixed version of distutils, but obviously not many 
pkgs consume that...
