This should not be a problem for the darcs buildslave, of course, darcs doesn't use the locally-installed gcc when it is built on Windows -- it uses the gcc that comes bundled inside the ghc distribution. ghc is still installed on that machine. However, the autoconf scripts test for the existence of gcc when they start, and discovering that there is no gcc installed, they immediately error out. You can follow the links in the appended buildbot mail to see what I mean. If someone can patch darcs so that it builds on Windows even when gcc is not installed, then that would be great, but if not then I'm afraid I'm going to remove the Windows buildslave from the darcs buildbot farm for now.

Oh no, I have a double standard---I'm quite willing to write crappy code for myself, as long as nobody ever sees it. But you've been quite polite with all my ranting, and I do believe this code is robust, although I'm not sure I tested it on anything three deep since after the day it was written. > Would you care to share your code? Here is a really hideous ksh script called 'nextbinary'. Your shell script does its thing and then something like exec `nextbinary $0` arguments ... nextbinary returns the next binary on the $PATH that is not the same file as the one passed in as a parameter. I had to write samefile.c to test to see if two files were the same file, since I couldn't find an easy way to do this from whatever ksh version I was using that year. I don't muck with $PATH but rather iterate through its elements explicitly. I'm sure a knowledgeable person could translate the ksh to bash. The samefile.c program is straightforward and not embarrassing.

Certainly it took me a moment to realize that your remark had no relation to the the unix rm(1) utility. FWIW, I feel that a lot of Wikipedia's changelog conventions are confusing, unnecessary, and not useful for Darcs (the project) to adopt. Trent W.

We can easily emulate the call to 'error' in BytestringUtils.hs by, I suspect, mapping over the String utf8-string produces us and calling error on it. (ie. 'unpackPSfromUTF8 = map (\x -> if x == '\xFFFD' then error "String corrupted" else x) . decode'). And odds are that the code in utf8-string is more reliable than the handrolled stuff in Darcs (although the obvious rebuttal to this suggestion is 'Well, it's worked pretty well for half a decade now.') - -- gwern -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEAREKAAYFAkkzT68ACgkQvpDo5Pfl1oL3IwCcCAcdZL5gIjhzBDsBZBlNrYV6 flgAoJf0blgkUkuajYDSFiRw6fGsCv7/ =A6/B -----END PGP SIGNATURE----- Gwern Branwen 2008-12-01T02:45:03 http://permalink.gmane.org/gmane.comp.version-control.darcs.user/16264 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 On Sun, Nov 30, 2008 at 7:13 PM, Trent W.

I think that --in-reply-to made this much easier!

There are plenty of other things for me to work on that I consider more important. If it bothers you sufficiently, you can work on the code for this yourself, or post a bounty for someone else to do so. It won't necessarily be accepted, but it'll be more productive (if less cathartic) than ranting at the list :-) Trent W.
