Hello all,
We've just had a user report an odd crash of Resolver. Importing the
standard library module 'decimal.py' blows up, meaning that Resolver
can't start.
We've eventually tracked it down. His machine has a Turkish locale. The
decimal module looks up global names by taking method names and looking
for an uppercase version (around line 2171 of the Python 2.4 standard
library module):
rounding_functions = [name for name in Decimal.__dict__.keys() if
name.startswith('_round_')]
for name in rounding_functions:
#name is like _round_half_even, goes to the global ROUND_HALF_EVEN value.
globalname = name[1:].upper()
val = globals()[globalname]
Decimal._pick_rounding_function[val] = name
The issue is because one of the method names is '_round_ceiling'. In the
Turkish locale, the uppercase version of this is "ROUND_CEİLİNG" (in
Turkish uppercase of "i" is "I" with a dot on top of it). Obviously the
lookup of the corresponding global fails.
In CPython the name is a byte-string, and so '.upper' just uses the
ascii uppercase rather than the locale sensitive version - so we see
failing to import 'decimal.py' as an IronPython bug. As this badly
impacts Resolver we would *love* to see this fixed soon...
Resolver is built on IronPython 1.1. Any word from you IP guys on how
quickly you can turnaround a new release of the 1.1 branch that
addresses this issue?
All the best,
