Add small run utilization to stats output. Add the 'util' column, which reports the proportion of available regions that are currently in use for each small size class. Small run utilization is the complement of external fragmentation. For example, utilization of 0.75 indicates that 25% of small run memory is consumed by external fragmentation, in other (more obtuse) words, 33% external fragmentation overhead. This resolves #27.

Fix MinGW build warnings. Conditionally define ENOENT, EINVAL, etc. (was unconditional). Add/use PRIzu, PRIzd, and PRIzx for use in malloc_printf() calls. gcc issued (harmless) warnings since e.g. "%zu" should be "%Iu" on Windows, and the alternative to this workaround would have been to disable the function attributes which cause gcc to look for type mismatches in formatted printing function calls.

Refactor huge allocation to be managed by arenas. Refactor huge allocation to be managed by arenas (though the global red-black tree of huge allocations remains for lookup during deallocation). This is the logical conclusion of recent changes that 1) made per arena dss precedence apply to huge allocation, and 2) made it possible to replace the per arena chunk allocation/deallocation functions. Remove the top level huge stats, and replace them with per arena huge stats. Normalize function names and types to *dalloc* (some were *dealloc*). Remove the --enable-mremap option. As jemalloc currently operates, this is a performace regression for some applications, but planned work to logarithmically space huge size classes should provide similar amortized performance. The motivation for this change was that mremap-based huge reallocation forced leaky abstractions that prevented refactoring.

Allow je_malloc_message to be overridden when linking statically If an application wants to override je_malloc_message, it is better to define the symbol locally than to change its value in main(), which might be too late for various reasons. Due to je_malloc_message being initialized in util.c, statically linking jemalloc with an application defining je_malloc_message fails due to "multiple definition of" the symbol. Defining it without a value (like je_malloc_conf) makes it more easily overridable.

Allow je_malloc_message to be overridden when linking statically If an application wants to override je_malloc_message, it is better to define the symbol locally than to change its value in main(), which might be too late for various reasons. Due to je_malloc_message being initialized in util.c, statically linking jemalloc with an application defining je_malloc_message fails due to "multiple definition of" the symbol. Defining it without a value (like je_malloc_conf) makes it more easily overridable.

Allow je_malloc_message to be overridden when linking statically If an application wants to override je_malloc_message, it is better to define the symbol locally than to change its value in main(), which might be too late for various reasons. Due to je_malloc_message being initialized in util.c, statically linking jemalloc with an application defining je_malloc_message fails due to "multiple definition of" the symbol. Defining it without a value (like je_malloc_conf) makes it more easily overridable.

Reduce cpp conditional logic complexity. Convert configuration-related cpp conditional logic to use static constant variables, e.g.: #ifdef JEMALLOC_DEBUG [...] #endif becomes: if (config_debug) { [...] } The advantage is clearer, more concise code. The main disadvantage is that data structures no longer have conditionally defined fields, so they pay the cost of all fields regardless of whether they are used. In practice, this is only a minor concern; config_stats will go away in an upcoming change, and config_prof is the only other major feature that depends on more than a few special-purpose fields.

The metadata statistics comprise the metadata categories as follows: - stats.metadata: All metadata -- base + arena chunk headers + internal allocations. - stats.arenas.<i>.metadata.mapped: Arena chunk headers. - stats.arenas.<i>.metadata.allocated: Internal allocations. This is reported separately from the other metadata statistics because it overlaps with the allocated and active statistics, whereas the other metadata statistics do not.

Don't use sizeof() on a VARIABLE_ARRAY In the alloca() case, this fails to be the right size.

Implement mallctl{nametomib,bymib}(). Replace chunk stats code that was missing locking; this fixes a race condition that could corrupt chunk statistics. Converting malloc_stats_print() to use mallctl*(). Add a missing semicolon in th DSS code. Convert malloc_tcache_flush() to a mallctl. Convert malloc_swap_enable() to a set of mallctl's.

Remove medium size classes. Remove medium size classes, because concurrent dirty page purging is no longer capable of purging inactive dirty pages inside active runs (due to recent arena/bin locking changes). Enhance tcache to support caching large objects, so that the same range of size classes is still cached, despite the removal of medium size class support.

Simplify malloc_message(). Rather than passing four strings to malloc_message(), malloc_write4(), and all the functions that use them, only pass one string.

Refactor jemalloc.c into multiple source files. Fix a stats bug in large object curruns accounting. Replace tcache_bin_fill() with arena_tcache_fill(), and fix a bug in an OOM error path. Fix API name mangling to coexist with __attribute__((malloc)).

Allow je_malloc_message to be overridden when linking statically If an application wants to override je_malloc_message, it is better to define the symbol locally than to change its value in main(), which might be too late for various reasons. Due to je_malloc_message being initialized in util.c, statically linking jemalloc with an application defining je_malloc_message fails due to "multiple definition of" the symbol. Defining it without a value (like je_malloc_conf) makes it more easily overridable.
