We use the memory address to detect reference to ''the same language object.''
While primarily a testing tool, this predicate is also used in the
core application at places, especially to prevent self-assignment
and to handle custom allocations.
It turns out that actually we need two flavours for convenient usage
- `isSameObject` uses strict comparison of address and accepts only references
- `isSameAdr` can also accept pointers and even void*, but will dereference pointers
This leads to some further improvements of helper utilities related to memory addresses...
part of the observed deviation stems form bugs in logging and checksum calculation;
but there seems to be a real problem hidden in the allocator usage of the
new component, since the use-cnt of the handle does not drop to zero
This adaptor works in concert with the generic allocator
building blocks (prospective ''Concepts'') and automatically
registers a either static or dynamic back-link to the factory
for clean-up.
Use this wrapper fore more in-depth test of the new `TrackingAllocator`
and verify proper behaviour through the `EventLog`
- create two vectors, attached to the `TrackingAllocator`
- emplace Tracker-Objects
- move an object to the other vector
- destroy the containers
🠲 Event-Log looks plausible!
- use a meta-registry of pools
- retrieve and manage the `MemoryPool` instances by shared_ptr, with a weak registry entry
- use a hastable for the allocations, keyed by the allocated memory address
- ability to verify a hash-checksum
- ability to watch number of allocations and allotted bytes
- using either a common global pool or a separate dedicated pool
- log all operations into a common `EventLog` instance
- front-end adaptors for use as C++ custom allocator
