* Remove Library_State::add_engine and Algorithm_Factory::add_engine,lloyd2008-11-123-35/+37
| | | | | | | | replacing with an updated constructor to Algorithm_Factory taking a vector of Engine*. The semantics of adding engines at runtime were not defined nor very clear, it seems best to prohibit this unless and until it is explicitly thought through (and until a need for it presents itself).

* Library_State had two functions that did the same thing,lloyd2008-11-127-65/+69
| | | | | | | | | | | | | | | algo_factory and algorithm_factory. This is confusing so for consistency/simplicity, remove algo_factory, making algorithm_factory the function to call. In 1.7.14, several functions in lookup.h, including retrieve_block_cipher, retrieve_hash, etc were changed to accept a Library_State& reference. However it turns out with the modified design I've settled upon for 1.8 that it is not necessary to change those interfaces; instead they always refer to the global_state algorithm factory which is exactly the semantics one would expect/desire 99% of the time (and is source compatible with code written for 1.6, also a plus)

| | | | | | | | Engine_Iterator (and thus the public key engine code) still processes in order of first engine to last in the list. Benchmarking confirmed that GNU MP is still faster than both OpenSSL and Botan for public key operations (at least on my machine).
* Oops, 2^32 nanoseconds < 4.3 seconds, which is pretty small. Use 64 bitlloyd2008-11-121-7/+7
| | | | | integers where we manipulate values denominated in nanoseconds to avoid overflow (2^64 nanoseconds = 584.55 years, aka long enough)
* Add an implementation of name() to Timer. This allows it to belloyd2008-11-121-0/+2
| | | | | | | | | instantiated directly, which seemd a useful thing since a Timer ref must be passed to the benchmark system. However I think due to the low resolution of clock() the results were highly variable. Using gettimeofday or clock_gettime (Unix_Timer, POSIX_Timer) proved more consistent and in sync with what the existing benchmarks show, so use one of those if possible.
* Remove support for provider identifiers from SCAN_Name - it turns out thislloyd2008-11-1216-213/+277
| | | | | | | | | | | | was not the right place to keep track of this information. Also modify all Algorithm_Factory constructor functions to take instead of a SCAN_Name a pair of std::strings - the SCAN name and an optional provider name. If a provider is specified, either that provider will be used or the request will fail. Otherwise, the library will attempt best effort, based on user-set algorithm implementation settings (combine with benchmark.h for choosing the fastest implementation at runtime) or if not set, a static ordering (preset in static_provider_weight in prov_weight.cpp, though it would be nice to make this easier to toggle).

* Make a change in how providers are requiested in Algorithm_Factory tolloyd2008-11-111-8/+24
| | | | | | | | | | | | | | | the engines. Unfortunately right now Botan doesn't understand that a construction like HMAC, while the basic HMAC class lives only in core, can use any of a variety of implementations as the underlying algorithm. The previous version got this completely wrong (basically the first time a particular HMAC was requested, one hash provider would be chosen at random). Now instead we always use the same subprovider. This means HMAC(SHA-1) won't see a speedup even if there is an asm version available (similarly, CMAC(AES) wouldn't see a speedup with OpenSSL's AES or an engine that provided AES using VIA's or Intel's extensions). Certainly a major deficiency, but I haven't worked out how to fix it yet.
* Move most of the remaining libstate code to pk_engine.cpp, move engineslloyd2008-11-1151-284/+128
