Re: Problems applying patches

because you said you had a problem with 37.

Oh, I see. Well, it seems to be OK now, at least in terms of applying 
the patches to the code using Stephane's instructions - I understand 
what's going on there now.


"make test" fails some of the tests at patch level 39 and patch level 
48. I'll investigate a bit more as I've only tried it on one of my Linux 
systems and post details if I can't work out what the problem is.

Is this a bash wildcard bug?

[grendelos]

So this is really bugging me.  Why is [a-z] not case sensitive, but [A-Z] is? 
For example:

# ls -l
total 0
-rw-r--r-- 1 root root 0 Nov 20 12:22 xa
-rw-r--r-- 1 root root 0 Nov 20 12:22 xA

# ls -l x[a-z]
-rw-r--r-- 1 root root 0 Nov 20 12:22 xa
-rw-r--r-- 1 root root 0 Nov 20 12:22 xA

# ls -l x[A-Z]
-rw-r--r-- 1 root root 0 Nov 20 12:22 xA

Any ideas?

Yes. Your assumptions are wrong.

[a-z] = [aAbBcCdD...xXyYz]
[A-Z] = [AbBcCdDe...XyYzZ]

Now... see why that gives the results you are seeing?

This is FAQ #1 regarding locales (sorry, no links handy, but GIYF). If 
you want the expected (case-sensitive) behavior, try 'export LC_ALL=C'.

So I tried building it on Fedora 9 and it built with no problems (up to 
and including patch level 48). "make test" produced a few warnings, but 
all of them were along the lines of "ignore this warning if there 
differences are only in whitespace" or containing the phrase "please do 
not consider this a test failure".


So on Fedora it's fine. I'll look at what's up on Xandros later.

Thanks again for all your help guys.

Oops, and I should have added that this depends on the locale. Very 
likely it is correct in this instance (perhaps omitting vowels with 
accents/etc that might also be in the set). But hopefully the idea - 
i.e. that the range '[a-z]' includes 'A' but not 'Z', and that '[A-Z]' 
includes 'z' but not 'a' - is clear.

You are using a locale that conflates upper- and lowercase as
aAbBcC...yYzZ.

Try it with: export LC_ALL=C
