2019-06-18Merge #12324: speed up Unserialize_impl for prevectorWladimir J. van der Laan
86b47fa741408b061ab0bda784b8678bfd7dfa88 speed up Unserialize_impl for prevector (Akio Nakamura) Pull request description: The unserializer for prevector uses `resize()` for reserve the area, but it's prefer to use `reserve()` because `resize()` have overhead to call its constructor many times. However, `reserve()` does not change the value of `_size` (a private member of prevector). This PR make the logic of read from stream to callback function, and prevector handles initilizing new values with that call-back and ajust the value of `_size`. The changes are as follows: 1. prevector.h Add a public member function named 'append'. This function has 2 params, number of elemenst to append and call-back function that initilizing new appended values. 2. serialize.h In the following two function: - `Unserialize_impl(Stream& is, prevector<N, T>& v, const unsigned char&)` - `Unserialize_impl(Stream& is, prevector<N, T>& v, const V&)` Make a callback function from each original logic of reading values from stream, and call prevector's `append()`. 3. test/prevector_tests.cpp Add a test for `append()`. ## A benchmark result is following: [Machine] MacBook Pro (macOS 10.13.3/i7 2.2GHz/mem 16GB/SSD) [result] DeserializeAndCheckBlockTest => 22% faster DeserializeBlockTest => 29% faster [before PR] # Benchmark, evals, iterations, total, min, max, median DeserializeAndCheckBlockTest, 60, 160, 94.4901, 0.0094644, 0.0104715, 0.0098339 DeserializeBlockTest, 60, 130, 65.0964, 0.00800362, 0.00895134, 0.00824187 [After PR] # Benchmark, evals, iterations, total, min, max, median DeserializeAndCheckBlockTest, 60, 160, 77.1597, 0.00767013, 0.00858959, 0.00805757 DeserializeBlockTest, 60, 130, 49.9443, 0.00613926, 0.00691187, 0.00635527 ACKs for top commit: laanwj: utACK 86b47fa741408b061ab0bda784b8678bfd7dfa88 Tree-SHA512: 62ea121ccd45a306fefc67485a1b03a853435af762607dae2426a87b15a3033d802c8556e1923727ddd1023a1837d0e5f6720c2c77b38196907e750e15fbb902

2019-02-03speed up Unserialize_impl for prevectorAkio Nakamura
The unserializer for prevector uses resize() for reserve the area, but it's prefer to use reserve() because resize() have overhead to call its constructor many times. However, reserve() does not change the value of "_size" (a private member of prevector). This PR introduce resize_uninitialized() to prevector that similar to resize() but does not call constructor, and added elements are explicitly initialized in Unserialize_imple(). The changes are as follows: 1. prevector.h Add a public member function named 'resize_uninitialized'. This function processes like as resize() but does not call constructors. So added elemensts needs explicitly initialized after this returns. 2. serialize.h In the following two function: Unserialize_impl(Stream& is, prevector<N, T>& v, const unsigned char&) Unserialize_impl(Stream& is, prevector<N, T>& v, const V&) Calls resize_uninitialized() instead of resize() 3. test/prevector_tests.cpp Add a test for resize_uninitialized().

2016-11-07test: Fix test_random includesMarcoFalke
2016-10-17Kill insecure_random and associated global stateWladimir J. van der Laan
There are only a few uses of `insecure_random` outside the tests. This PR replaces uses of insecure_random (and its accompanying global state) in the core code with an FastRandomContext that is automatically seeded on creation. This is meant to be used for inner loops. The FastRandomContext can be in the outer scope, or the class itself, then rand32() is used inside the loop. Useful e.g. for pushing addresses in CNode or the fee rounding, or randomization for coin selection. As a context is created per purpose, thus it gets rid of cross-thread unprotected shared usage of a single set of globals, this should also get rid of the potential race conditions. - I'd say TxMempool::check is not called enough to warrant using a special fast random context, this is switched to GetRand() (open for discussion...) - The use of `insecure_rand` in ConnectThroughProxy has been replaced by an atomic integer counter. The only goal here is to have a different credentials pair for each connection to go on a different Tor circuit, it does not need to be random nor unpredictable. - To avoid having a FastRandomContext on every CNode, the context is passed into PushAddress as appropriate. There remains an insecure_random for test usage in `test_random.h`.
