2017-04-10Set BCLog::LIBEVENT correctly for old libevent versions.John Newbery
2017-04-01Change LogAcceptCategory to use uint32_t rather than sets of strings.Gregory Maxwell
This changes the logging categories to boolean flags instead of strings. This simplifies the acceptance testing by avoiding accessing a scoped static thread local pointer to a thread local set of strings. It eliminates the only use of boost::thread_specific_ptr outside of lockorder debugging. This change allows log entries to be directed to multiple categories and makes it easy to change the logging flags at runtime (e.g. via an RPC, though that isn't done by this commit.) It also eliminates the fDebug global. Configuration of unknown logging categories now produces a warning.

2016-07-28httpserver: replace boost threads with stdCory Fields
along with mutex/condvar/bind/etc. httpserver handles its own interruption, so there's no reason not to use std threading. While we're at it, may as well kill the BOOST_FOREACH's as well.
2016-07-28httpserver: explicitly detach worker threadsCory Fields
When using std::thread in place of boost::thread, letting the threads destruct results in a std::terminate. According to the docs, the same thing should be be happening in later boost versions: http://www.boost.org/doc/libs/1_55_0/doc/html/thread/thread_management.html#thread.thread_management.thread.destructor I'm unsure why this hasn't blown up already, but explicitly detaching can't hurt.

2016-05-05http: Do a pending c++11 simplificationWladimir J. van der Laan
Use std::unique_ptr for handling work items. This makes the code more RAII and, as mentioned in the comment, is what I planned when I wrote the code in the first place.
2016-04-28auto_ptr → unique_ptrWladimir J. van der Laan
Change the few occurrences of the deprecated `auto_ptr` to c++11 `unique_ptr`. Silences the deprecation warnings. Also add a missing `std::` for consistency.

2015-11-20http: add Boost 1.49 compatibilityWladimir J. van der Laan
`try_join_for` was introduced in Boost 1.50: http://www.boost.org/doc/libs/1_50_0/doc/html/thread/thread_management.html#thread.thread_management.thread.try_join_for 1.49 has `timed_join`, one can accomplish the same with: http://www.boost.org/doc/libs/1_49_0/doc/html/thread/thread_management.html#thread.thread_management.thread.timed_join However, `timed_join` was deprecated in 1.50. So a conditional is necessary. This solution was tested in #7031.
2015-11-16Avoid a compile error on hosts with libevent too old for EVENT_LOG_WARN.Gregory Maxwell
This uses _EVENT_LOG_WARN instead, which appears to be defined in the old versions of libevent that I have on some systems.
2015-11-13http: speed up shutdownWladimir J. van der Laan
This continues/fixes #6719. `event_base_loopbreak` was not doing what I expected it to, at least in libevent 2.0.21. What I expected was that it sets a timeout, given that no other pending events it would exit in N seconds. However, what it does was delay the event loop exit with 10 seconds, even if nothing is pending. Solve it in a different way: give the event loop thread time to exit out of itself, and if it doesn't, send loopbreak. This speeds up the RPC tests a lot, each exit incurred a 10 second overhead, with this change there should be no shutdown overhead in the common case and up to two seconds if the event loop is blocking. As a bonus this breaks dependency on boost::thread_group, as the HTTP server minds its own offspring.
2015-10-20http: Restrict maximum size of request line + headersWladimir J. van der Laan
Prevent memory exhaustion by sending lots of data. Also add a test to `httpbasics.py`. Closes #6425
2015-09-28http: Force-exit event loop after predefined timeWladimir J. van der Laan
This makes sure that the event loop eventually terminates, even if an event (like an open timeout, or a hanging connection) happens to be holding it up.
2015-09-28http: Wait for worker threads to exitWladimir J. van der Laan
Add a WaitExit() call to http's WorkQueue to make it delete the work queue only when all worker threads stopped. This fixes a problem that was reproducable by pressing Ctrl-C during AppInit2: ``` /usr/include/boost/thread/pthread/condition_variable_fwd.hpp:81: boost::condition_variable::~condition_variable(): Assertion `!ret' failed. /usr/include/boost/thread/pthread/mutex.hpp:108: boost::mutex::~mutex(): Assertion `!posix::pthread_mutex_destroy(&m)' failed. ``` I was assuming that `threadGroup->join_all();` would always have been called when entering the Shutdown(). However this is not the case in bitcoind's AppInit2-non-zero-exit case "was left out intentionally here".
2015-09-28Make HTTP server shutdown more gracefulWladimir J. van der Laan
Shutting down the HTTP server currently breaks off all current requests. This can create a race condition with RPC `stop` command, where the calling process never receives confirmation. This change removes the listening sockets on shutdown so that no new requests can come in, but no longer breaks off requests in progress. Meant to fix #6717.
