2012-03-29cast: make sure suncc sees a constant.Rusty Russell2-8/+22
cast_const() et. al. are supposed to be a constant expression, so you can do things like: static char *p = cast_const(char *, (const char *)"hello"); Unfortunately, a cast to intptr_t and arithmetic makes suncc reject it as a constant expression. We need the cast, because (1) the expression could be a void *, so we can't just add to it, and (2) gcc complains with -Wcast-qual without it. So instead of adding BUILD_BUG_OR_ZERO, we use a ? :, which keeps everyone happy.

2012-03-29cast: test/compile_fail-cast_static.c should fail without COMPOUND_LITERALS.Rusty Russell1-3/+9
It still gave a warning on gcc, because casting a char to a char* gives a warning. Not so on sun CC. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 6569a707d169a629e25e10710c760c8dc84525c7)
2012-03-22lib/ccan/failtest: compile fix for OpenBSDRusty Russell3-0/+17
OpenBSD doesn't idempotent-wrap sys/mman.h, so when we #define mmap to an alternative, it fails to compile when sys/mman.h is included again. Workaround is not to #define mmap to add arguments on Open BSD. (Imported from CCAN commit e18e80fe175422d26efe689addc0f67bdba0e097) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-03-22lib/ccan: namespacize ccan/list to avoid conflict with OpenIndiana's sys/list.hRusty Russell20-357/+392
CCAN includes a little utility called "namespacize" which prepends ccan_ to all public methods of a module, and fixes up any dependencies it finds. It's a little primitive, but it works here. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-03-08failtest: don't assume FD_SETSIZE is maximum runtime fd.Rusty Russell3-3/+68
This breaks when rlimit is less. Unfortunately, valgrind (32 bit x86, 3.7.0.SVN, Ubuntu) fails to set the file limit properly on the test: reducing it to the obvious getrlimit/setrlimit/getrlimit works fine, so leaving diagnostics for another day.

2011-12-05lib/ccan/htable: benchmark against hsearch(3)Rusty Russell3-2/+108
Since that has a fixed hash table size and doesn't support delete, we can't do a thorough comparison, but we can insert and search. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 95757f0e9d979e7c653e9b53bb640deb4f0ea1f9)
2011-12-05lib/ccan/likely: use htable_typeRusty Russell3-66/+80
Also general cleanups: (1) Don't assume that strings are folded by the compiler. (2) Implement likely_stats_reset(). (3) Return non-const string from likely_stats(), as caller must free it. (4) Don't use struct info indirection (that was from when we used callbacks?) (5) Close memory leak in run-debug.c Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 0e5d0e30b30bb07b6605843e5ff224210d8083d8)
