#include "config.h"
Update ccan/structeq. structeq() is too dangerous: if a structure has padding, it can fail silently. The new ccan/structeq instead provides a macro to define foo_eq(), which does the right thing in case of padding (which none of our structures currently have anyway). Upgrade ccan, and use it everywhere. Except run-peer-wire.c, which is only testing code and can use raw memcmp(): valgrind will tell us if padding exists. Interestingly, we still declared short_channel_id_eq, even though we didn't define it any more! Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

routing: Added IRC announcement glue Added channel announcement serialization and parsing, as well as the entrypoints for the IRC peer discovery. Announcements are signed by the sending endpoint and signatures are verified before adding the channels to the local view of the topology. We do not yet verify the existence of the anchor transaction.

Force the use of the POSIX C locale for all commands and their subprocesses

common/utils: don&#39;t free tmpctx, just the children. In some daemons I want to hand it into a loop, which would call clean_tmpctx(). This causes a subtle bug. So just free the children directly: the pointer itself remains valid. Signed-off-by: Rusty Russell &lt;rusty@rustcorp.com.au&gt;

/* Global temporary convenience context: children freed in io loop core. */
utils: add a global tmpctx. I did a brief audit of tmpctx uses, and we do leak them in various corner cases. Fortunely, all our daemons are based on some kind of I/O loop, so it&#39;s fairly easy to clean a global tmpctx at that point. This makes things a bit neater, and slightly more efficient, but also clearer: I avoided creating a tmpctx in a few places because I didn&#39;t want to add another allocation. With that penalty removed, I can use it more freely and hopefully write clearer code. Signed-off-by: Rusty Russell &lt;rusty@rustcorp.com.au&gt;

tal_tmpctx: clear marker for temporary contexts. This makes them stand out in memory dumps. Also plug two existing memory leaks. Signed-off-by: Rusty Russell &lt;rusty@rustcorp.com.au&gt;
