Yinan Zhang	6945371778	Change tsdn to tsd for profiling code path	2019-11-22 16:31:56 -08:00
Yinan Zhang	b55419f9b9	Restructure profiling ... Develop new data structure and code logic for holding profiling related information stored in the extent that may be needed after the extent is released, which in particular is the case for the reallocation code path (e.g. in `rallocx()` and `xallocx()`). The data structure is a generalization of `prof_tctx_t`: we previously only copy out the `prof_tctx` before the extent is released, but we may be in need of additional fields. Currently the only additional field is the allocation time field, but there may be more fields in the future. The restructuring also resolved a bug: `prof_realloc()` mistakenly passed the new `ptr` to `prof_free_sampled_object()`, but passing in the `old_ptr` would crash because it's already been released. Now the essential profiling information is collectively copied out early and safely passed to `prof_free_sampled_object()` after the extent is released.	2019-11-22 16:31:56 -08:00
Qi Wang	ccfe68a916	Pass alloc_ctx down profiling path. ... With this change, when profiling is enabled, we avoid doing redundant rtree lookups. Also changed dalloc_atx_t to alloc_atx_t, as it's now used on allocation path as well (to speed up profiling).	2017-04-12 13:55:39 -07:00
David Goldblatt	0a0fcd3e6a	Add hooking functionality ... This allows us to hook chosen functions and do interesting things there (in particular: reentrancy checking).	2017-04-07 14:10:27 -07:00
Jason Evans	5e67fbc367	Push down iealloc() calls. ... Call iealloc() as deep into call chains as possible without causing redundant calls.	2017-03-22 18:33:32 -07:00
Jason Evans	de49674fbd	Use MALLOC_CONF rather than malloc_conf for tests. ... malloc_conf does not reliably work with MSVC, which complains of "inconsistent dll linkage", i.e. its inability to support the application overriding malloc_conf when dynamically linking/loading. Work around this limitation by adding test harness support for per test shell script sourcing, and converting all tests to use MALLOC_CONF instead of malloc_conf.	2017-02-23 08:57:02 -08:00
Jason Evans	c4c2592c83	Update brace style. ... Add braces around single-line blocks, and remove line breaks before function-opening braces. This resolves #537.	2017-01-20 21:43:07 -08:00
Jason Evans	1ff09534b5	Fix prof_realloc() regression. ... Mostly revert the prof_realloc() changes in 498856f44a (Move slabs out of chunks.) so that prof_free_sampled_object() is called when appropriate. Leave the prof_tctx_[re]set() optimization in place, but add an assertion to verify that all eight cases are correctly handled. Add a comment to make clear the code ordering, so that the regression originally fixed by ea8d97b897 (Fix prof_{malloc,free}_sample_object() call order in prof_realloc().) is not repeated. This resolves #499.	2017-01-17 15:16:37 -08:00
