evhttpd implementation - *Replace usage of boost::asio with [libevent2](http://libevent.org/)*. boost::asio is not part of C++11, so unlike other boost there is no forwards-compatibility reason to stick with it. Together with #4738 (convert json_spirit to UniValue), this rids Bitcoin Core of the worst offenders with regard to compile-time slowness. - *Replace spit-and-duct-tape http server with evhttp*. Front-end http handling is handled by libevent, a work queue (with configurable depth and parallelism) is used to handle application requests. - *Wrap HTTP request in C++ class*; this makes the application code mostly HTTP-server-neutral - *Refactor RPC to move all http-specific code to a separate file*. Theoreticaly this can allow building without HTTP server but with another RPC backend, e.g. Qt's debug console (currently not implemented) or future RPC mechanisms people may want to use. - *HTTP dispatch mechanism*; services (e.g., RPC, REST) register which URL paths they want to handle. By using a proven, high-performance asynchronous networking library (also used by Tor) and HTTP server, problems such as #5674, #5655, #344 should be avoided. What works? bitcoind, bitcoin-cli, bitcoin-qt. Unit tests and RPC/REST tests pass. The aim for now is everything but SSL support. Configuration options: - `-rpcthreads`: repurposed as "number of work handler threads". Still defaults to 4. - `-rpcworkqueue`: maximum depth of work queue. When this is reached, new requests will return a 500 Internal Error. - `-rpctimeout`: inactivity time, in seconds, after which to disconnect a client. - `-debug=http`: low-level http activity logging

*
* This is the developer documentation of the reference client for an experimental new digital currency called Dash (https://www.dash.org/),
2015-03-18 00:06:58 +01:00
* which enables instant payments to anyone, anywhere in the world. Dash uses peer-to-peer technology to operate
* with no central authority: managing transactions and issuing money are carried out collectively by the network.
*
* The software is a community-driven open source project, released under the MIT license.
*
* \section Navigation
* Use the buttons <code>Namespaces</code>, <code>Classes</code> or <code>Files</code> at the top of the page to start navigating the code.

Enable stacktrace support in gitian builds (#3006) * Remove use of -rdynamic This causes check-symbols to fail horribly and also turned out to be not required when using libbacktrace. It was only required when using "backtrace()" from "<execinfo.h>" * Remove spurious ], from configure.ac * Add -DENABLE_STACKTRACES=1 to CMakeLists.txt * Remove unused method my_backtrace_simple_callback * Use fs::path().filename() instead of basename() * Add static g_exeFileName and g_exeFileBaseName * Use .exe.dbg file when available * Use uint64_t instead of uintptr_t * Implement GetBaseAddress() for unix and win32 * Implement unified crash_info and use it everywhere before printing crash info * Print a serialized version of crash_info when there is no debug info * Implement "-printcrashinfo" command line option * Compile stacktrace support unconditionally and only make crash hooks conditional This also renames the --enable-stacktraces option to --enable-crash-hooks * Enable crash hooks in win/linux Gitian builds * Try to load .debug file on MacOS and enable crash hooks for osx Gitian builds * Check for dsymutil and if it needs --flat * Create .debug files in osx Gitian build * Handle review comments * Also print crash description when no stacktrace is available * Unconditionally add -g1 debug information Instead of making it dependent on "--enable-crash-hooks". We will need the debug info every time now, even in release builds. * Put MacOS debug info into dSYM symbols instead of plain .debug files * Implement MacOS specific GetBaseAddress
