* Move assert.h from internal to very public (included in types.h)lloyd2013-03-131-1/+0
| | | | | | This reduces friction to writing an assert, so hopefully there will be more of them as a result. And we can use asserts in public headers now, very useful for templates.
* Add new helper zap which zeros a vector, clears it, and then callslloyd2012-11-291-0/+12

* Use uintptr_t in ptr_in_pool instead of size_t as uintptr_t is nowlloyd2012-07-132-6/+4
| | | | | | | | standard in C++11 and makes more sense than size_t Make m_poolsize a const. There is no real reason to reset it to zero if a failure occurs since a) we are throwing an exception anyway and b) we check for !m_pool first thing.
* Add deleted copy constructors/assignment operators where appropriate.lloyd2012-07-101-0/+4
| | | | | Replace C++98 style private copy constructors/assignment ops with ones annotated with delete.

* Avoid integer overflows in calls to the mlock allocator, changing thelloyd2012-06-113-20/+44
| | | | | | | interface to more of a calloc style. Alignment remains set to the underlying type size. Increase the maximum mlock size to 512 KB.

* Only build the mlock allocator on Linux, *BSD, or Solaris.lloyd2012-05-261-0/+8
| | | | | As best I can tell those are the only Unix kernels that allow unprivledged users to mlock memory.
* Two more locking_allocator bugs. In allocate, we did not setlloyd2012-05-251-5/+9
| | | | | | | | | | | best_fit->first in cases where we had an almost exact match (exact fit but with some alignment bytes at the start), meaning that not only would we lose those bytes forever, but that we might later hand out a range overlapping with what we handed to our current caller. Also, in deallocate, lower_bound on the freelist might return end() (for instance if the freelist is entirely empty). Avoid trying to update the iterator in that case.
* Fix alignment again and add assert checks so we don't mess up again.lloyd2012-05-251-4/+30
| | | | | | We previously ignored a block that was exactly the right size for the allocation and the needed alignment. If we find such a block prefer it over any other (non-exact) blocks to minimize fragmentation.
* For block and stream ciphers, don't set the size of the key vectorslloyd2012-05-251-0/+8
| | | | | | | | | | | until we are actually setting a key. This avoids the problem of prototype objects consuming not just memory but the precious few bytes of mlock'able memory that we're given by Linux. Use clear_mem instead of a loop in BigInt::mask_bits If OS2ECP encounters an invalid format type, include what type it was in the exception message.
* Instead of a map of start->length for recording the free list use alloyd2012-05-242-33/+44
| | | | | | vector of (start,length) where we are careful to maintain the correct ordering. Much much faster than the map version as it mostly avoids allocations and copies.
* Properly align return values of mlock_allocator. Be more careful aboutlloyd2012-05-221-13/+34
| | | | | | | | | | | pointer checks as a sufficiently smart compiler might optimize way pointer comparisons otherwise. Avoid using an iterator value after we have released it from the map. Reduce the default buffer size to 1K to reduce pressure on mlock memory. Drop the old mlock wrapper code.
* Remove a debug call in secmem.h.lloyd2012-05-224-4/+220
| | | | | | | | | Add a new mlock allocator which is far superior to the previous one both in terms of behavior (will lock exactly as much memory as we can actually mlock and will fall back to new/delete in all other cases), and much better and much simpler freelist than the old mem_pool code. Currently we only support systems with mmap+mlock, however it should be easy to extend to also support Windows VirtualLock if desired.
* Replace 0 and NULL pointer constants with nullptr. Also fix an oldlloyd2012-05-181-3/+4
| | | | style cast in secmem.h
* Fairly huge update that replaces the old secmem types with std::vectorlloyd2012-05-1812-1109/+63
| | | | | | using a custom allocator. Currently our allocator just does new/delete with a memset before deletion, and the mmap and mlock allocators have been removed.
* First step towards replacing the existing containers with std::vectorlloyd2012-05-181-11/+25
| | | | | | with a custom allocator; remove the 3 argument version of MemoryRegion::copy, replacing with freestanding buffer_insert function.
