2015-04-09ccan/list/list.h: sync with ccan upstreamnormal
This includes the following 5 commits from ccan upstream: list: list_add_after and list_add_before functions list: list_swap to exchange elements list: new list_for_each{, _safe}_off_dir_ macros list: add list_for_each_rev_off macro list: add list_for_each_rev_safe{,_off} macros This syncs us with commit c2fbfe5282ba264f3485586e7efa8a5967f2d386 in git:// These ccan commits should allow us to implement compile.c and st.c using ccan/list to reduce duplicated linked-list logic. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2014-09-13ccan/container_of: add container_of_or_nullnormal
* ccan/container_of/container_of.h (container_of_or_null): added [ccan 7ec5b8e06b2fd5fa98b1fcde1158c286d2d429d8] (David Gibson) It's quite common to have a pointer which could be either a pointer to a structure member, or NULL. This needs special casing with container_of(), or it will convert NULL into something strange. This patch adds container_of_or_null(), which will return NULL if passed (an appropriately typed) NULL, or the containining structure as container_of() otherwise. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2014-05-10vm*: doubly-linked list from ccan to manage vm->living_threadsnormal
A doubly-linked list for tracking living threads guarantees constant-time insert/delete performance with no corner cases of a hash table. I chose this ccan implementation of doubly-linked lists over the BSD sys/queue.h implementation since: 1) insertion and removal are both branchless 2) locality is improved if a struct may be a member of multiple lists (0002 patch in Feature 9632 will introduce a secondary list for waiting FDs) This also increases cache locality during iteration: improving performance in a new IO#close benchmark with many sleeping threads while still scanning the same number of threads. vm_thread_close 1.762 * vm_core.h (rb_vm_t): list_head and counter for living_threads (rb_thread_t): vmlt_node for living_threads linkage (rb_vm_living_threads_init): new function wrapper (rb_vm_living_threads_insert): ditto (rb_vm_living_threads_remove): ditto * vm.c (rb_vm_living_threads_foreach): new function wrapper * thread.c (terminate_i, thread_start_func_2, thread_create_core, thread_fd_close_i, thread_fd_close): update to use new APIs * vm.c (vm_mark_each_thread_func, rb_vm_mark, ruby_vm_destruct, vm_memsize, vm_init2, Init_VM): ditto * vm_trace.c (clear_trace_func_i, rb_clear_trace_func): ditto * benchmark/bm_vm_thread_close.rb: added to show improvement * ccan/build_assert/build_assert.h: added as a dependency of list.h * ccan/check_type/check_type.h: ditto * ccan/container_of/container_of.h: ditto * ccan/licenses/BSD-MIT: ditto * ccan/licenses/CC0: ditto * ccan/str/str.h: ditto (stripped of unused macros) * ccan/list/list.h: ditto * add CCAN_LIST_INCLUDES [ruby-core:61871][Feature 9632 (part 1)] Apologies for the size of this commit, but I think a good doubly-linked list will be useful for future features, too. This may be used to add ordering to a container_of-based hash table to preserve compatibility if required (e.g. feature 9614). git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
