2023-11-19pool: make sure PoolAllocator uses the correct alignmentMartin Leitner-Ankerl
This changes the PoolAllocator to default the alignment to the given type. This makes the code simpler, and most importantly fixes a bug on ARM 32bit that caused OOM: The class CTxOut has a member CAmount which is an int64_t and on ARM 32bit int64_t are 8 byte aligned which is larger than the pointer alignment of 4 bytes. So for CCoinsMap to be able to use the pool, we need to use the alignment of the member instead of just alignof(void*).

2023-07-24Don't derive secure_allocator from std::allocatorCasey Carter
Affects both secure_allocator and zero_after_free_allocator. Giving the C++ Standard Committee control of the public interface of your type means they will break it. C++23 adds a new `allocate_at_least` member to `std::allocator`. Very bad things happen when, say, `std::vector` uses `allocate_at_least` from `secure_allocator`'s base to allocate memory which it then tries to free with `secure_allocator::deallocate`. Drive-by: Aggressively remove facilities unnecessary since C++11 from both allocators to keep things simple.

Any identifier starting with two _, or one _ followed by a capital letter is reserved for the compiler and thus must not be used.

2023-03-23Add pool based memory resource & allocatorMartin Leitner-Ankerl
A memory resource similar to std::pmr::unsynchronized_pool_resource, but optimized for node-based containers. Co-Authored-By: Pieter Wuille <pieter@wuille.net>
2023-02-21Pass all characters to SecureString including nullsJohn Moffett
`SecureString` is a `std::string` specialization with a secure allocator. However, it's treated like a C- string (no explicit length and null-terminated). This can cause unexpected behavior. For instance, if a user enters a passphrase with an embedded null character (which is possible through Qt and the JSON-RPC), it will ignore any characters after the null, giving the user a false sense of security. Instead of assigning `SecureString` via `std::string::c_str()`, assign it via a `std::string_view` of the original. This explicitly captures the size and doesn't make any extraneous copies in memory.

Includes allocator::pointer, allocator::const_pointer, allocator::reference and allocator::const_reference which are deprecated in c++17 and removed in c++20. See https://en.cppreference.com/w/cpp/memory/allocator Also prefer `using` over `typedef` see: https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rt-using

2016-10-27support: Add LockedPoolWladimir J. van der Laan
Add a pool for locked memory chunks, replacing LockedPageManager. This is something I've been wanting to do for a long time. The current approach of locking objects where they happen to be on the stack or heap in-place causes a lot of mlock/munlock system call overhead, slowing down any handling of keys. Also locked memory is a limited resource on many operating systems (and using a lot of it bogs down the system), so the previous approach of locking every page that may contain any key information (but also other information) is wasteful.

Pagelocker is only needed for secure (usually wallet) operations, so don't make the zero-after-free allocator depend on it.
