kme : brokenness   8

maint: skip a check when en_US.UTF-8 collation rules are broken
On OS X, *.UTF-8 locales use ASCII collating rules(!?):
<code class="language-bash">readlink /usr/share/locale/*.UTF-8/LC_COLLATE|sort -u
# result: ../la_LN.US-ASCII/LC_COLLATE</code>

This means that sort, and any other program that relies on strcoll,
cannot be expected to work consistently on OS X in any UTF-8 locale.

Issue 23195: Sorting with locale (strxfrm) does not work properly with Python3 on BSD or OS X - Python tracker
What is 'ln_LA' anyway?
The initial difference appears to be a long-standing BSD (including OS X) versus GNU/Linux platform difference. See, for example:

Why there is no difference between en and fr UTF-8 is obvious when you look under the covers at the system locale definitions. This is on FreeBSD 10, OS X 10.10 is the same:

$ cd /usr/share/locale/fr_FR.UTF-8/
$ ls -l
total 8
lrwxr-xr-x 1 root wheel 28 Jan 16 2014 LC_COLLATE -> ../la_LN.US-ASCII/LC_COLLATE
lrwxr-xr-x 1 root wheel 17 Jan 16 2014 LC_CTYPE -> ../UTF-8/LC_CTYPE
lrwxr-xr-x 1 root wheel 30 Jan 16 2014 LC_MESSAGES -> ../fr_FR.ISO8859-1/LC_MESSAGES
-r--r--r-- 1 root wheel 36 Jan 16 2014 LC_MONETARY
lrwxr-xr-x 1 root wheel 29 Jan 16 2014 LC_NUMERIC -> ../fr_FR.ISO8859-1/LC_NUMERIC
-r--r--r-- 1 root wheel 364 Jan 16 2014 LC_TIME

For some reason US-ASCII is used for UTF-8 collation; this is also true for en_US.UTF-8 and de_DE.UTF-8, the only other ones I checked.

The postresq discussion and some earlier Python issues suggest using ICU to properly implement Unicode functions like collation across all platforms. But that has never been implemented in Python. Nosing Marc-Andre.

Problems with sort order (UTF8 locales don't work) · Issue #216 · PostgresApp/PostgresApp
you can see the reason for this with ls -l /usr/share/locale/de_DE.UTF-8 you see that LC_COLLATE only symlinks to la_LN.US-ASCII. You get the same if you sort something on the shell, so it's a OS specific, not PG specific problem. AFAIR this affects all BSD OS.

Some ML posts of Tom Lane in that topic:

It seems we will have to wait for , use a different OS or use a function for sorting, that can internally use ICU form pl/perl, unaccent contrib, or your own implementation.

To me this is the biggest drawback of using PostgresApp (PostgreSQL on OSX in general) and something that should be clearly highlighted in the documentation.

@macarthy in principle, yes. You'd just need to create a new database with the collation. However, as a word of caution, UTF-8 locales seem to be fundamentally broken on OSX. Postgres uses the strcoll API, which unfortunately does not support multibyte encodings on OSX.

Sorting strings properly is stupidly hard – Daniel Lemire's blog
However, I tried to test out the sorting on fr_ca locale and got the incorrect answer, which I found out was due to incorrect locale settings on Max OS X/BSD. On my machine, fr_FR.UTF-8 collation is linked to la_LN.US-ASCII

macos - Add a locale in Mac OSX - Stack Overflow
Looking into this found that, as of Mac OS X 10.10.3, collation is still broken for Spanish and most European languages. Collation definitions for these locales are linked to an ASCII definition. This ends up breaking things such as ORDER BY clauses on PostgreSQL.

Also, WTF is does 'la_LN' mean anyway?

What I Learned From Dating Women Who Have Been Raped []
The idea that, if someone knew I didn’t want to do something sexual that they shouldn’t do it, was completely alien to me, and yet made total sense. Would I continue with an activity if my partner clearly didn’t want me to? Is that the way you would treat a person you cared about? We talk a lot now about affirmative consent and whatnot, but unfortunately we can’t legislate the actual change that needs to be made. Men need to care when they are making women suffer. People need to care when they make each other suffer.

I think my experience fighting back contrasts with another memory when a female friend got hit by a male friend in the face except she didn’t retaliate. I remember her getting ice for her face and needing a lot of comfort from her friends even though I’m not sure the punch was that hard, and it seemed strange then. Now, however, I think what happened was that she was trying to heal an emotional hurt. She was forced to absorb male anger without being allowed to express any anger herself, and something about that is deeply fucked in a way that’s hard to articulate.

More than any explicit action, this societal expectation for me to provide nurturance to the very people who resent me has poisoned me. It requires my complete effacement, for me to deny the value of my own experience. It has required a betrayal of the most personal kind, and to recover from it necessitates re-learning one of the most basic human instincts.

My own suffering matters.
