2021-07-09util/uri: do not check argument of uri_free()Heinrich Schuchardt
uri_free() checks if its argument is NULL in uri_clean() and g_free(). There is no need to check the argument before the call.

2018-06-29cutils: Provide strchrnulKeno Fischer
strchrnul is a GNU extension and thus unavailable on a number of targets. In the review for a commit removing strchrnul from 9p, I was asked to create a qemu_strchrnul helper to factor out this functionality. Do so, and use it in a number of other places in the code base that inlined the replacement pattern in a place where strchrnul could be used.

2018-03-05util/uri.c: wrap single statement blocks with braces {}Su Hang
For this patch, using curly braces to wrap `if` `while` `else` statements, which only hold single statement. For example: ''' if (cond) statement; ''' to ''' if (cond) { statement; } ''' And using tricks that compare the disassemblies before and after code changes, to make sure code logic isn't changed: ''' git checkout master make util/uri.o strip util/uri.o objdump -Drx util/uri.o > /tmp/uri-master.txt git checkout cleanupbranch make util/uri.o strip util/uri.o objdump -Drx util/uri.o > /tmp/uri-cleanup.txt Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2015-02-10util/uri: URI member path can be null, compare more carfullyMarkus Armbruster
uri_resolve_relative() calls strcmp(bas->path, ref->path). However, either argument could be null! Evidence: the code checks for null after the comparison. Spotted by Coverity. I suspect this was screwed up when we stole the code from libxml2. There the conditional reads xmlStrEqual((xmlChar *)bas->path, (xmlChar *)ref->path) with int xmlStrEqual(const xmlChar *str1, const xmlChar *str2) { if (str1 == str2) return(1); if (str1 == NULL) return(0); if (str2 == NULL) return(0); do { if (*str1++ != *str2) return(0); } while (*str2++); return(1); } Fix by replicating libxml2's logic faithfully.
