From 19247e5510279f018f8358a72b38cc5aa62fac8a Mon Sep 17 00:00:00 2001 From: Pierre Habouzit Date: Thu, 20 Sep 2007 10:43:11 +0200 Subject: nfv?asprintf are broken without va_copy, workaround them. * drop nfasprintf. * move nfvasprintf into imap-send.c back, and let it work on a 8k buffer, and die() in case of overflow. It should be enough for imap commands, if someone cares about imap-send, he's welcomed to fix it properly. * replace nfvasprintf use in merge-recursive with a copy of the strbuf_addf logic, it's one place, we'll live with it. To ease the change, output_buffer string list is replaced with a strbuf ;) * rework trace.c to call vsnprintf itself. It's used to format strerror()s and git command names, it should never be more than a few octets long, let it work on a 8k static buffer with vsnprintf or die loudly.
