Ups - the error is not reproducible for me. I think you can just close this bug.

I'd like to open this back up, since I just ran into the same problem with
MediaWiki 1.6.8.  The culprit is --disable-posix ...

When attempting to upgrade an old, old wiki from 1.4.5 to 1.6.8, I ran across
the following problem:

$ php upgrade1_5.php 
piratedgames 2006-09-06 05:22:29: Checking cur table for unique title index and
applying if necessary
piratedgames: cur table has the old non-unique index and may have duplicate entries.
Checking for duplicate cur table entries... (this may take a while on a large wiki)
Found 0 titles with duplicate entries.
piratedgames 2006-09-06 05:22:30: ...converting from cur/old to
page/revision/text DB structure.
piratedgames 2006-09-06 05:22:30: Creating page and revision tables...
PHP Fatal error:  Call to undefined function:  posix_isatty() in
/www/ on line 469
Fatal error: Call to undefined function:  posix_isatty() in
/www/ on line 469

The documentation on posix-isatty()  <> barely
exists.  However, the main POSIX page in the manual
<> clearly states that "POSIX functions
are enabled by default. You can disable POSIX-like functions with --disable-posix".

So, Database.php expects certain POSIX functions to exist, and they don't on my
build.  As far as I can tell, the MediaWiki documentation does not mention that
MediaWiki requires PHP to be compiled with the POSIX functions, or that using
--disable-posix will create problems.

For those of us with hardened systems who want to run 1.6.x or 1.7.x, this
clearly presents a problem.

For the interested, here's my full config line:

Comment 3 Brion Vibber 2006-09-06 09:30:49 UTC
MediaWiki assumes you haven't gone out of your way to break PHP.
Comment 4 Chad H. 2010-01-25 00:05:07 UTC
Marking this FIXED. Install/update has checked function_exists( 'posix_isatty' ) for awhile now.
