25246070ae fix double free check in secure = 4 mode; inline _mi_ptr_cookie 2019-10-19 08:34:18 -07:00
daan
2affdbbd2e stronger secure mode when defining MI_SECURE=4: checks for double free, corrupted free list, and invalid pointer frees. Performance is impacted but not too much -- more perf testing is needed 2019-10-18 18:11:04 -07:00

559688ec64 Suppress warning about unnamed struct 
This prevents MSVC complaining with

	warning C4201: nonstandard extension used: nameless struct/union

The struct might seem unnecessary to the occasional reader (it did seem
so to this commit's author), but it is not! It is required to align the
fields to a boundary, which is verified by the test suite. Removing that
"unnecessary" `struct` results in this failure:

1: Test command: mimalloc-test-api
[...]
1: test: malloc-zero...  mimalloc: assertion failed: at src/page.c:591, mi_page_init
1:   assertion: "!mi_page_has_aligned(page)"

e747a6f3a6 Use unsigned for bit-field variables 
It is actually non-standard to use `bool` with a bit-field quantifier,
and VS 2019 complains about this.

b5e26bedb1 Enforce strict include-what-you-use policy 
The include-what-you-use (IWYU) policy is beneficial to faster
compilation and fewer recompilations. Many build tools, such as GNU make,
provide a mechanism for automatically figuring out what .h files a .cc
file depends on. These mechanisms typically look at #include lines. When
unnecessary #includes are listed, the build system is more likely to
recompile in cases where it is not necessary.

With the enforcement, header file <include/mimalloc.h> no longer
includes <stdlib.h>.

8dba36bcec Use checked unsigned multiplication extension of GCC/Clang 
Most processors have carry flags which they set on addition overflow, so
it is a good idea to access them whenever possible. Most of them also
have widening multiply instructions that can be used to detect overflow
of the non-widening version. Both GCC and Clang offer a way to detect an
overflow for security critical applications.

a667971cbf Apple rebrands "OS X" as "macOS" 
In 2012, with the release of OS X 10.8 Mountain Lion, the name of the
system was shortened from Mac OS X to OS X. In 2016, with the release
of macOS 10.12 Sierra, the name was changed from OS X to macOS to
streamline it with the branding of Apple's other primary operating
systems: iOS, watchOS, and tvOS.
