* pkg/csource: tidy generated codeDmitry Vyukov2018-07-271-4/+2
| | | | | | | | | | | 1. Remove unnecessary includes. 2. Remove thunk function in threaded mode. 3. Inline syscalls into main for the simplest case. 4. Define main in common.h rather than form with printfs. 5. Fix generation for repeat mode (we had 2 infinite loops: in main and in loop). 6. Remove unused functions (setup/reset_loop, setup/reset_test, sandbox_namespace, etc).
* executor: overhaulDmitry Vyukov2018-07-241-151/+11
| | | | | | | | | | | | | | | | | Make as much code as possible shared between all OSes. In particular main is now common across all OSes. Make more code shared between executor and csource (in particular, loop function and threaded execution logic). Also make loop and threaded logic shared across all OSes. Make more posix/unix code shared across OSes (e.g. signal handling, pthread creation, etc). Plus other changes along similar lines. Also support test OS in executor (based on portable posix) and add 4 arches that cover all execution modes (fork server/no fork server, shmem/no shmem). This change paves way for testing of executor code and allows to preserve consistency across OSes and executor/csource.
* executor: introduce uint64/32/16/8 typesDmitry Vyukov2017-12-271-3/+3
| | | | | | | | | | | | | | | The "define uint64_t unsigned long long" were too good to work. With a different toolchain I am getting: cstdint:69:11: error: expected unqualified-id using ::uint64_t; ^ executor/common.h:34:18: note: expanded from macro 'uint64_t' Do it the proper way: introduce uint64/32/16/8 types and use them. pkg/csource then does s/uint64/uint64_t/ to not clutter code with additional typedefs.
* executor: check format stringsDmitry Vyukov2017-12-271-4/+2
| | | | | | | | | | | | | | | | | | | I see a crash which says: #0: too much cover 0 (errno 0) while the code is: uint64_t n = ...; if (n >= kCoverSize) fail("#%d: too much cover %u", th->id, n); It seems that the high part of n is set, but we don't see it. Add printf format attribute to fail and friends and fix all similar cases. Caught a bunch of similar cases and a missing argument in: exitf("opendir(%s) failed due to NOFILE, exiting");
* executor: fix netbsd syscallsDmitry Vyukov2017-10-251-0/+164
executor_netbsd.cc was including syscalls_freebsd.h, which completely messed up syscall numbers and names. Include the right syscalls header.
