* Set tcmalloc heap limit prior to testing oomAliaksey Kandratsenka2021-02-281-0/+5
| | | | Otherwise it can take long time to OOM on osex.
* correctly check sized delete hint when asserts are onAliaksey Kandratsenka2021-02-281-0/+17
| | | | | | | | | | | | We previously tested wrong assumption that larger than page size size classes have addresses aligned on page size. New code is making proper check of size class. Also added is unit test coverage for this previously failing condition. And we now also run "assert-ful" unittests for big tcmalloc too, not only tcmalloc_minimal configuration. This fixes github issue #1254
* add missing noopt wrappings around more operator new callsAliaksey Kandratsenka2021-02-211-4/+4
| | | | | This fixes tests passing on clang which otherwise eliminates those new/delete calls so checking for hooks being called failed.
* use standard way to print size_t-sized intsAliaksey Kandratsenka2021-02-141-1/+1
| | | | | | I.e. just use zu/zd/zx instead of finding out right size and defining PRI{u,x,d}S defines. Compilers have long caught up to this part of standard.
* don't test sbrk hook if we're on linux and don't have __sbrkAliaksey Kandratsenka2020-07-111-1/+1
| | | | | | | | | "mmap" hooks code for linux only hooks sbrk when __sbrk is defined. But musl doesn't offer this function (reasonably so), so sbrk hooking doesn't work there. Not big loss, but lets make sure tests don't fail. Lets reference this to issue #1198
* liberate gperftools tests from relying on -fno-builtin-XXX flagsAliaksey Kandratsenka2020-07-061-33/+35
| | | | | | Clang mostly ignores those anyways, so our tests needed better way to disable optimizations (clang is quite aggressive replacing new/delete pair with stack allocation).
* Add tests for sized deallocationHolyWu2018-04-291-1/+31

* Don't test OOM handling of debugallocatorAliaksey Kandratsenka2018-03-241-2/+5
| | | | | | | | | | | | | This may fix issue #969. When testing OOM handling we set up sys allocator that fails memory allocation. But debugallocator itself allocates some internal metadata memory via malloc and crashes if those allocations fail. So occasionally this test failed when debugallocator's internal malloc ended up causing sys allocator. So instead of failing tests from time to time, we drop it for debug allocator. It's OOM handling is already crashy anyways.
* Implemented O(log n) searching among large spansAliaksey Kandratsenka2018-02-251-1/+1
| | | | | | | | | | | | | | | | | | This is implemented via std::set with custom STL allocator that delegates to PageHeapAllocator. Free large spans are not linked together via linked list, but inserted into std::set. Spans also store iterators to std::set positions pointing to them. So that removing span from set is fast too. Patch implemented by Aliaksey Kandratsenka and Todd Lipcon based on earlier research and experimentation by James Golick. Addresses issue #535 [alkondratenko@gmail.com: added Todd's fix for building on OSX] [alkondratenko@gmail.com: removed unnecessary Span constructor] [alkondratenko@gmail.com: added const for SpanSet comparator] [alkondratenko@gmail.com: added operator != for STLPageHeapAllocator]
* unbreak throw declarations on operators new/deleteAliaksey Kandratsenka2017-11-291-1/+1
| | | | | | | | | | | | | | | | | | | | | We now clearly separate PERFTOOLS_NOTHROW (used for tc_XXX functions) and throw()/noexcept (used for operators we define). The former is basically "nothrow() for our callers, nothing for us". It is roughly equivalent of what glibc declares for malloc and friends. If some exception-full C++ code calls such function it doesn't have to bother setting up exception handling around such call. Notably, it is still important for those functions to _not have throw() declarations when we're building tcmalloc. Because C++ throw() requires setting up handling of unexpected exceptions thrown from under such functions which we don't want. The later is necessary to have operators new/delete definitions have "correct" exception specifications to calm down compiler warnings. Particularly older clang versions warn if new/delete aren't defined with correct exception specifications. Also this commit fixes annoying gcc 7+ warning (and gnu++14 mode) that complains about throw() being deprecated.
* Fix OOM handling in fast-pathAliaksey Kandratsenka2017-11-291-0/+66
| | | | | | | | | | | | Previous fast-path malloc implementation failed to arrange proper oom handling for operator new. I.e. operator new is supposed to call new handler and throw exception, which was not arranged in fast-path case. Fixed code now passes pointer for oom function to ThreadCache::FetchFromCentralCache which will call it in oom condition. Test is added to verify correct behavior. I've also updated some fast-path-related comments for more accuracy.
* Add support for C++17 operator new/delete for overaligned types.Andrey Semashev2017-11-291-0/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add auto-detection of std::align_val_t presence to configure scripts. This indicates that the compiler supports C++17 operator new/delete overloads for overaligned types. - Add auto-detection of -faligned-new compiler option that appeared in gcc 7. The option allows the compiler to generate calls to the new operators. It is needed for tests. - Added overrides for the new operators. The overrides are enabled if the support for std::align_val_t has been detected. The implementation is mostly based on the infrastructure used by memalign, which had to be extended to support being used by C++ operators in addition to C functions. In particular, the debug version of the library has to distinguish memory allocated by memalign from that by operator new. The current implementation of sized overaligned delete operators do not make use of the supplied size argument except for the debug allocator because it is difficult to calculate the exact allocation size that was used to allocate memory with alignment. This can be done in the future. - Removed forward declaration of std::nothrow_t. This was not portable as the standard library is not required to provide nothrow_t directly in namespace std (it could use e.g. an inline namespace within std). The <new> header needs to be included for std::align_val_t anyway. - Fixed operator delete[] implementation in libc_override_redefine.h. - Moved TC_ALIAS definition to the beginning of the file in tcmalloc.cc so that the macro is defined before its first use in nallocx. - Added tests to verify the added operators.

* don't use arg-ful constructor attribute for early nallocx testAliaksey Kandratsenka2017-05-211-7/+0
| | | | | | | 101 is not very early anyways and arg-ful constructor attribute is only supported since gcc 4.3 (and e.g. rhel 5's compiler fails to compile it). So there seems to be very little value trying to ask for priority of 101.
* fix compilation of tcmalloc_unittest.cc on older llvm-gccAliaksey Kandratsenka2017-05-141-0/+6

* Don't assume memalign exists in memalign vs nallocx testAliaksey Kandratsenka2017-02-201-1/+1
| | | | | | | OSX and windows have issues with memalign. So test against tc_memalign instead. This should fix _memalign linker-time part of issue #870.
* ported nallocx support from Google-internal tcmallocAliaksey Kandratsenka2016-12-181-0/+47
| | | | | | | | | | | | | | | nallocx is extension introduced by jemalloc. It returns effective size of allocaiton without allocating anything. We also support MALLOCX_LG_ALIGN flag. But all other jemalloc flags (which at the moment do nothing for nallocx anyways) are silently ignored, since there is no sensible way to return errors in this API. This was originally contributed by Dmitry Vyukov with input from Andrew Hunter. But due to significant divergence of Google-internal and free-software forks of tcmalloc, significant massaging was done by me. So all bugs are mine.
* Call function pointers with the right typeBrian Silverman2016-03-051-12/+14
| | | | | I think it's undefined behavior, but it's definitely weird. ubsan complains too.
* unbreak TestErrno againAliaksey Kandratsenka2015-09-261-1/+1
| | | | | Somehow in previous commit I managed to break assignment of memalign result to variable being tested. Luckily gcc gave me warning.

* added tc_malloc_skip_new_handlerAliaksey Kandratsenka2014-04-011-0/+5
| | | | | | | | | | | | This is port of corresponding chromium change at: https://codereview.chromium.org/55333002/ Basic idea is that sometimes apps that use tc_set_new_mode in order to have C++ out-of-memory handler catch OOMs in malloc, need to invoke usual malloc that returns 0 on OOM. That new API is exactly for that. It'll always return NULL on OOM even if tc_new_mode is set to true.
