...ad bug in udev if compiled with klibc. I seems that the needle string can't have a strlen of 1. This test case illustrates it: #include <stdio.h> #include <string.h> int main(int argc, char *argv[], char *envp[]) { char *hay = "a/b"; char *needle = "/"; if (memmem(hay, strlen(hay), needle, strlen(needle)) == NULL) printf("This uses the 'Not So Naive' algorithm... Which is broken. :)\n"); else printf("ok\n"); } Thanks, Kay

While working on can_FOO caching, at one point I got confused by whether 'readonly' meant the global set by -r or a local passed to .open(). A quick attempt to compile with -Wshadow found several other confusing points; this series gets us to the point that we can add -Wshadow to builds with --enable-gcc-warnings.

Hello, I work at SmarctJog.com, we have here some patches on IceCast for performance and reliability, these are mostly client/connection/source cleanups (a slave merge is underway, and some more good stuff (c)), but we'd like this to be merged in before the list gets any longer. Please find attached a list of our patches with a short desc: This one is actually not from us/me, it was found

I've been taking a long hard look at the protocol layer. It has evolved over a long time without any particular direction, and the result is, to say the least, not very organized. These patches take a first step at cleaning up the mess by abstracting out socket operations from the rest of the code. The purpose of this is to allow us to slot in a different connection layer under the

This is an extended version of: https://www.redhat.com/archives/libguestfs/2019-September/msg00178.html It adds a couple of simple code changes, so it makes it possible to drop more modules. In addition, more unused modules were dropped. Pino Toscano (5): tests: switch away from xgetcwd daemon: move read_whole_file to common utils daemon: switch from read_file to read_whole_file daemon:
