(2f33e00 Jardel Weyrich) - o Fixed a fd leak in start_accepting(), plus cosmetic changes (4367a33 Jardel Weyrich) - o Improved error handling in evconnlistener_new_async(). Also keeping the fd open because it is not opened by this function, so the caller is responsible for closing it. Additionally, since evconnlistener_new_bind() creates a socket and passes it to the function above, it required error checking to close the same socket.

(4faeaea) - - - -Changes in 2.0.3-alpha (20 Nov 2009): - o Add a new code to support SSL/TLS on bufferevents, using the OpenSSL library (where available). - o Fix a bug where we didn't allocate enough memory in event_get_supported_methods(). - o Avoid segfault during failed allocation of locked evdns_base. (Found by Rocco Carbone.) - o Export new evutil_ascii_* functions to perform locale-independent character type operations. - o Try to compile better with MSVC: patches from Brodie Thiesfield - o New evconnlistener_get_fd function to expose a listener's associated socket. - o Expose an ev_socklen_t type for consistent use across platforms. - o Make bufferevent_socket_connect() work when the original fd was -1. - o Fix a bug in bufferevent_socket_connect() when the connection succeeds too quickly. - o Export an evutil_sockaddr_cmp() to compare to sockaddr objects for equality. - o Add a bufferevent_get_enabled() to tell what a bufferevent has been configured to do. - o Add an evbuffer_search_eol() function to locate the end of a line nondestructively. - o Add an evbuffer_search_range() function to search a bounded range of a buffer. - o Fix a rare crash bug in evdns. - o Have bufferevent_socket_connect() with no arguments put a bufferevent into connecting mode. - o Support sendfile on Solaris: patch from Caitlin Mercer. - o New functions to explicitly reference a socket used by an evhttp object. Patches from David Reiss. - o When we send a BEV_EVENT_CONNECTED to indicate connected status, we no longer invoke the write callback as well unless we actually wrote data too. - o If the kernel tells us that there are a negative number of bytes to read from a socket, do not believe it. Fixes bug 2841177; found by Alexander Pronchenkov. - o Do not detect whether we have monotonic clock support every time a new event base is created: instead do it only once. Patch taken from Chromium. - o Do not allocate the maximum event queue for the epoll backend at startup. Instead, start out accepting 32 events at a time, and double the queue's size when it seems that the OS is generating events faster than we're requesting them. Saves up to 374K per epoll-based event_base. Resolves bug 2839240. - o Treat an event with a negative fd as valid but untriggerable by Libevent. This is useful for applications that want to manually activate events. - o Fix compilation on Android, which forgot to define fd_mask in its sys/select.h - o Do not drop data from evbuffer when out of memory; reported by Jacek Masiulaniec - o New event_base_got_exit() and event_base_got_break() functions to tell whether an event loop exited because of an event_base_loopexit() or an event_base_loopbreak(). Patch from Ka-Hing Cheung. - o When adding or deleting an event from a non-main thread, only wake up the main thread when its behavior actually needs to change. - o Fix some bugs when using the old evdns interfaces to initialize the evdns module. - o Detect errors during bufferevent_connect(). Patch from Christopher Davis. - o Fix compilation for listener.h for C++ - missing extern "C". Patch from Ferenc Szalai. - o Make the event_base_loop() family of functions respect thread-safety better. This should clear up a few hard-to-debug race conditions. - o Fix a bug when using a specialized memory allocator on win32. - o Have the win32 select() backend label TCP-socket-connected events as EV_WRITE, not EV_READ. This should bring it in line with the other backends, and improve portability. Patch from Christopher Davis. - o Stop using enums as arguments or return values when what we mean is a bitfield of enum values. C++ doesn't believe that you can OR two enum values together and get another enum, and C++ takes its typing seriously. Patch from Christopher Davis. - o Add an API to replace all fatal calls to exit() with a user-provided panic function. - o Replace all assert() calls with a variant that is aware of the user-provided logging and panic functions. - o Add a return value to event_assign so that it can fail rather than asserting when the user gives it bad input. event_set still dies on bad input. - o The event_base_new() and event_base_new_with_config() functions now never call exit() on failure. For backward "compatibility", event_init() still does, but more consistently. - o Remove compat/sys/_time.h. It interfered with system headers on HPUX, and its functionality has been subsumed by event2/util.h and util-internal.h. - o Add a new bufferevent_socket_connect_hostname() to encapsulate the resolve-then-connect operation. - o Build kqueue.c correctly on GNU/kFreeBSD platforms. Patch pulled upstream from Debian. - o Alternative queue-based timeout algorithm for programs that use a large number of timeouts with the same value. - o New event_base_config option to disable the timeval cache entirely. - o Make EV_PERSIST timeouts more accurate: schedule the next event based on the scheduled time of the previous event, not based on the current time. - o Allow http.c to handle cases where getaddrinfo returns an IPv6 address. Patch from Ryan Phillips. - o Fix a problem with excessive memory allocation when using multiple event priorities. - o Default to using arc4random for DNS transaction IDs on systems that have it; from OpenBSD. - o Never check the environment when we're running setuid or setgid; from OpenBSD. - o Options passed to evdns_set_option() no longer need to end with a colon. - o Add an evutil_getaddrinfo() function to clone getaddrinfo on platforms that don't have it. - o Add an evdns_getaddrinfo() function to provide a nonblocking getaddrinfo using evdns, so programs can perform useful hostname lookup. - o Finally expose the IOCP-based bufferevent backend. It passes its unit tests, but probably still has some bugs remaining. Code by Nick Mathewson and Christopher Davis. - o Numerous other bugfixes. - o On FreeBSD and other OSes, connect can return ECONREFUSED immediately; instead of failing the function call, pretend with faileld in the callback. - o Fix a race condition in the pthreads test case; found by Nick Mathewson - o Remove most calls to event_err() in http and deal with memory errors instead - - - -Changes in 2.0.2-alpha (25 Jul 2009): - o Add a new flag to bufferevents to make all callbacks automatically deferred. - o Make evdns functionality locked, and automatically defer dns callbacks. - o Fix a possible free(NULL) when freeing an event_base with no signals. - o Add a flag to disable checking environment varibles when making an event_base - o Disallow setting less than 1 priority. - o Fix a bug when removing a timeout from the heap. [Patch from Marko Kreen] - o Use signal.h, not sys/signal.h. [Patch from mmadia] - o Try harder to build with certain older c99 compilers. - o Make sure that an event_config's flags field is always initialized to 0. [Bug report from Victor Goya] - o Avoid data corruption when reading data entirely into the second-to-last chain of an evbuffer. [Bug report from Victor Goya] - o Make sendfile work on FreeBSD - o Do not use vararg macros for accessing evrpc structures; this is not backwards compatible, but we did not promise any backwards compatibility for the rpc code. - o Actually define the event_config_set_flag() function. - o Try harder to compile with Visual C++. - o Move event_set() and its allies to event2/event_compat.h where they belong. - o Remove the event_gotsig code, which has long been deprecated and unused. - o Add an event_get_base() function to return the base assigned to an event. - o New function to automate connecting on a socket-based bufferevent. - o New functions to automate listening for incoming TCP connections. - o Do case-insensitive checks with a locale-independent comparison function. - o Rename the evbuffercb and everrorcb callbacks to bufferevent_data_cb and bufferevent_event_cb respectively. The old names are available in bufferevent_compat.h. - o Rename the EVBUFFER_* codes used by bufferevent event callbacks to BEV_EVENT_*, to avoid namespace collision with evbuffer flags. The old names are available in bufferevent_compat.h. - o Move the EVBUFFER_INPUT and EVBUFFER_OUTPUT macros to bufferevent_compat.h - o Add a bufferevent_getfd() function to mirror bufferevent_setfd() - o Make bufferevent_setfd() return an error code if the operation is not successful. - o Shave 22 bytes off struct event on 32-bit platforms by shrinking and re-ordering fields. The savings on 64-bit platforms is likely higher. - o Cap the maximum number of priorities at 256. - o Change the semantics of evbuffer_cb_set_flags() to be set-flag only; add a new evbuffer_cb_clear_flags() to remove set flags. - o Change the interface of evbuffer_add_reference so that the cleanup callback gets more information - o Revise the new evbuffer_reserve_space/evbuffer_commit_space() interfaces so that you can use them without causing extraneous copies or leaving gaps in the evbuffer. - o Add a new evbuffer_peek() interface to inspect data in an evbuffer without removing it. - o Fix a deadlock when suspending reads in a bufferevent due to a full buffer. (Spotted by Joachim Bauch.) - o Fix a memory error when freeing a thread-enabled event base with registered events. (Spotted by Joachim Bauch.) - o Try to contain degree of failure when running on a win32 version so heavily firewalled that we can't fake a socketpair. - o Activate fd events in a pseudorandom order with O(N) backends, so that we don't systematically favor low fds (select) or earlier-added fds (poll, win32). - o Replace some read()/write() instances with send()/recv() to work properly on win32. - o Set truncated flag correctly in evdns server replies. - o Raise RpcGenError in event_rpcgen.py; from jmanison and Zack Weinberg - o Fix preamble of rpcgen-generated files to rely on event2 includes; based on work by jmansion; patch from Zack Weinberg. - o Allow specifying the output filename for rpcgen; based on work by jmansion; patch from Zack Weinberg. - o Allow C identifiers as struct names; allow multiple comments in .rpc files; from Zack Weinberg - o Mitigate a race condition when using socket bufferevents in multiple threads. - o Use AC_SEARCH_LIBS, not AC_CHECK_LIB to avoid needless library use. - o Do not allow event_del(ev) to return while that event's callback is executing in another thread. This fixes a nasty race condition. - o event_get_supported_methods() now lists methods that have been disabled with the EVENT_NO* environment options. - o Rename encode_int[64] to evtag_encode_int[64] to avoid polluting the global namespace. The old method names are still available as macros in event2/tag_compat.h. - - - -Changes in 2.0.1-alpha (17 Apr 2009): - o free minheap on event_base_free(); from Christopher Layne - o debug cleanups in signal.c; from Christopher Layne - o provide event_base_new() that does not set the current_base global - o bufferevent_write now uses a const source argument; report from Charles Kerr - o improve documentation on event_base_loopexit; patch from Scott Lamb - o New function, event_{base_}loopbreak. Like event_loopexit, it makes an event loop stop executing and return. Unlike event_loopexit, it keeps subsequent pending events from getting executed. Patch from Scott Lamb - o Check return value of event_add in signal.c - o provide event_reinit() to reintialize an event_base after fork - o New function event_set_mem_functinons. It allows the user to give libevent replacement functions to use for memory management in place of malloc(), free(), etc. This should be generally useful for memory instrumentation, specialized allocators, and so on. - o The kqueue implementation now catches signals that are raised after event_add() is called but before the event_loop() call. This makes it match the other implementations. - o The kqueue implementation now restores original signal handlers correctly when its signal events are removed. - o Check return value of event_add in signal.c - o Add a more powerful evbuffer_readln as a replacement for evbuffer_readline. The new function handles more newline styles, and is more useful with buffers that may contain a nul characters. - o Do not mangle socket handles on 64-bit windows. - o The configure script now takes an --enable-gcc-warnigns option that turns on many optional gcc warnings. (Nick has been building with these for a while, but they might be useful to other developers.) - o move EV_PERSIST handling out of the event backends - o small improvements to evhttp documentation - o always generate Date and Content-Length headers for HTTP/1.1 replies - o set the correct event base for HTTP close events - o When building with GCC, use the "format" attribute to verify type correctness of calls to printf-like functions. - o Rewrite win32.c backend to be O(n lg n) rather than O(n^2). - o Removed obsoleted recalc code - o support for 32-bit tag numbers in rpc structures; this is wire compatible, but changes the API slightly. - o pull setters/getters out of RPC structures into a base class to which we just need to store a pointer; this reduces the memory footprint of these structures. - o prefix {encode,decode}_tag functions with evtag to avoid collisions - o fix a bug with event_rpcgen for integers - o Correctly handle DNS replies with no answers set (Fixes bug 1846282) - o add -Wstrict-aliasing to warnings and more cleanup - o removed linger from http server socket; reported by Ilya Martynov - o event_rpcgen now allows creating integer arrays - o support string arrays in event_rpcgen - o change evrpc hooking to allow pausing of RPCs; this will make it possible for the hook to do some meaning ful work; this is not backwards compatible. - o allow an http request callback to take ownership of a request structure - o allow association of meta data with RPC requests for hook processing - o associate more context for hooks to query such as the connection object - o remove pending timeouts on event_base_free() - o also check EAGAIN for Solaris' event ports; from W.C.A. Wijngaards - o devpoll and evport need reinit; tested by W.C.A Wijngaards - o event_base_get_method; from Springande Ulv - o Send CRLF after each chunk in HTTP output, for compliance with RFC2626. Patch from "propanbutan". Fixes bug 1894184. - o Add a int64_t parsing function, with unit tests, so we can apply Scott Lamb's fix to allow large HTTP values. - o Use a 64-bit field to hold HTTP content-lengths. Patch from Scott Lamb. - o Allow regression code to build even without Python installed - o remove NDEBUG ifdefs from evdns.c - o detect integer types properly on platforms without stdint.h - o udpate documentation of event_loop and event_base_loop; from Tani Hosokawa. - o simplify evbuffer by removing orig_buffer - o do not insert event into list when evsel->add fails - o add support for PUT/DELETE requests; from Josh Rotenberg - o introduce evhttp_accept_socket() to accept from an already created socket - o include Content-Length in reply for HTTP/1.0 requests with keep-alive - o increase listen queue for http sockets to 128; if that is not enough the evhttp_accpet_socket() api can be used with a prepared socket. - o Patch from Tani Hosokawa: make some functions in http.c threadsafe. - o test support for PUT/DELETE requests; from Josh Rotenberg - o rewrite of the evbuffer code to reduce memory copies - o Some older Solaris versions demand that _REENTRANT be defined to get strtok_r(); do so. - o Do not free the kqop file descriptor in other processes, also allow it to be 0; from Andrei Nigmatulin - o Provide OpenSSL style support for multiple threads accessing the same event_base - o make event_rpcgen.py generate code include event-config.h; reported by Sam Banks. - o switch thread support so that locks get allocated as they are needed. - o make event methods static so that they are not exported; from Andrei Nigmatulin - o make RPC replies use application/octet-stream as mime type - o do not delete uninitialized timeout event in evdns - o Correct the documentation on buffer printf functions. - o Don't warn on unimplemented epoll_create(): this isn't a problem, just a reason to fall back to poll or select. - o Correctly handle timeouts larger than 35 minutes on Linux with epoll.c. This is probably a kernel defect, but we'll have to support old kernels anyway even if it gets fixed. - o Make name_from_addr() threadsafe in http.c - o Add new thread-safe interfaces to evdns functions. - o Make all event_tagging interfaces threadsafe. - o Rename internal memory management functions. - o New functions (event_assign, event_new, event_free) for use by apps that want to be safely threadsafe, or want to remain ignorant of the contents of struct event. - o introduce bufferevent_read_buffer; allows reading without memory copy. - o expose bufferevent_setwatermark via header files and fix high watermark on read - o fix a bug in buffrevent read water marks and add a test for them - o fix a bug in which bufferevent_write_buffer would not schedule a write event - o provide bufferevent_input and bufferevent_output without requiring knowledge of the structure - o introduce bufferevent_setcb and bufferevent_setfd to allow better manipulation of bufferevents - o convert evhttp_connection to use bufferevents. - o use libevent's internal timercmp on all platforms, to avoid bugs on old platforms where timercmp(a,b,<=) is buggy. - o Remove the never-exported, never-used evhttp_hostportfile function. - o Support input/output filters for bufferevents; somewhat similar to libio's model. This will allow us to implement SSL, compression, etc, transparently to users of bufferevents such as the http layer. - o allow connections to be removed from an rpc pool - o add new evtimer_assign, signal_assign, evtimer_new, and signal_new functions to manipulate timer and signal events, analagous to the now-recommended event_assign and event_new - o switch internal uses of event_set over to use event_assign. - o introduce evbuffer_contiguous_space() api that tells a user how much data is available in the first buffer chain - o introduce evbuffer_reserve_space() and evbuffer_commit_space() to make processing in filters more efficient. - o reduce system calls for getting current time by caching it. - o separate signal events from io events; making the code less complex. - o support for periodic timeouts - o support for virtual HTTP hosts. - o turn event_initialized() into a function, and add function equivalents to EVENT_SIGNAL and EVENT_FD so that people don't need to include event_struct.h - o Build test directory correctly with CPPFLAGS set. - o Provide an API for retrieving the supported event mechanisms. - o event_base_new_with_config() and corresponding config APIs. - o migrate the evhttp header to event2/ but accessors are still missing. - o deprecate timeout_* event functions by moving them to event_compat.h - o Move windows gettimeofday replacement into a new evutil_gettimeofday(). - o Make configure script work on IRIX. - o provide a method for canceling ongoing http requests. - o Make vsnprintf() returns consistent on win32. - o Fix connection keep-alive behavior for HTTP/1.0 - o Fix use of freed memory in event_reinit; pointed out by Peter Postma - o constify struct timeval * where possible - o make event_get_supported_methods obey environment variables - o support for edge-triggered events on epoll and kqueue backends: patch from Valery Kholodkov - o support for selecting event backends by their features, and for querying the features of a backend. - o change failing behavior of event_base_new_with_config: if a config is provided and no backend is selected, return NULL instead of aborting. - o deliver partial data to request callbacks when chunked callback is set even if there is no chunking on the http level; allows cancelation of requests from within the chunked callback; from Scott Lamb. - o allow min_heap_erase to be called on removed members; from liusifan. - o Rename INPUT and OUTPUT to EVRPC_INPUT and EVRPC_OUTPUT. Retain INPUT/OUTPUT aliases on on-win32 platforms for backwards compatibility. - o Do not use SO_REUSEADDR when connecting - o Support 64-bit integers in RPC structs - o Correct handling of trailing headers in chunked replies; from Scott Lamb. - o Support multi-line HTTP headers; based on a patch from Moshe Litvin - o Reject negative Content-Length headers; anonymous bug report - o Detect CLOCK_MONOTONIC at runtime for evdns; anonymous bug report - o Various HTTP correctness fixes from Scott Lamb - o Fix a bug where deleting signals with the kqueue backend would cause subsequent adds to fail - o Support multiple events listening on the same signal; make signals regular events that go on the same event queue; problem report by Alexander Drozdov. - o Fix a problem with epoll() and reinit; problem report by Alexander Drozdov. - o Fix off-by-one errors in devpoll; from Ian Bell - o Make event_add not change any state if it fails; reported by Ian Bell. - o Fix a bug where headers arriving in multiple packets were not parsed; fix from Jiang Hong; test by me. - o Match the query in DNS replies to the query in the request; from Vsevolod Stakhov. - o Add new utility functions to correctly observe and log winsock errors. - o Do not remove Accept-Encoding header - o Clear the timer cache on entering the event loop; reported by Victor Chang - o Only bind the socket on connect when a local address has been provided; reported by Alejo Sanchez - o Allow setting of local port for evhttp connections to support millions of connections from a single system; from Richard Jones. - o Clear the timer cache when leaving the event loop; reported by Robin Haberkorn - o Fix a typo in setting the global event base; reported by lance. - o Set the 0x20 bit on outgoing alphabetic characters in DNS requests randomly, and insist on a match in replies. This helps resist DNS poisoning attacks. - o Make the http connection close detection work properly with bufferevents and fix a potential memory leak associated with it. - o Restructure the event backends so that they do not need to keep track of events themselves, as a side effect multiple events can use the same fd or signal. - o Add generic implementations for parsing and emiting IPv6 addresses on platforms that do not have inet_ntop and/or inet_pton. - o Allow DNS servers that have IPv6 addresses. - o Add an evbuffer_write_atmost() function to write a limited number of bytes to an fd. - o Refactor internal notify-main-thread logic to prefer eventfd to pipe, then pipe to socketpair, and only use socketpairs as a last resort. - o Try harder to pack all evbuffer reads into as few chains as possible, using readv/WSARecv as appropriate. - o New evthread_use_windows_threads() and evthread_use_pthreads() functions to set up the evthread callbacks with reasonable defaults. - o Change the semantics of timeouts in conjunction with EV_PERSIST; timeouts in that case will now repeat until deleted. - o sendfile, mmap and memory reference support for evbuffers. - o New evutil_make_listen_socket_reuseable() to abstract SO_REUSEADDR. - o New bind-to option to allow DNS clients to bind to an arbitrary port for outgoing requests. - o evbuffers can now be "frozen" to prevent operations at one or both ends. - o Bufferevents now notice external attempts to add data to an inbuf or remove it from an outbuf, and stop them. - o Fix parsing of queries where the encoded queries contained \r, \n or + - o Do not allow internal events to starve lower-priority events. - -Changes in 1.4.0: - o allow \r or \n individually to separate HTTP headers instead of the standard "\r\n"; from Charles Kerr. - o demote most http warnings to debug messages - o Fix Solaris compilation; from Magne Mahre - o Add a "Date" header to HTTP responses, as required by HTTP 1.1. - o Support specifying the local address of an evhttp_connection using set_local_address - o Fix a memory leak in which failed HTTP connections whould not free the request object - o Make adding of array members in event_rpcgen more efficient, but doubling memory allocation - o Fix a memory leak in the DNS server - o Fix compilation when DNS_USE_OPENSSL_FOR_ID is enabled - o Fix buffer size and string generation in evdns_resolve_reverse_ipv6(). - o Respond to nonstandard DNS queries with "NOTIMPL" rather than by ignoring them. - o In DNS responses, the CD flag should be preserved, not the TC flag. - o Fix http.c to compile properly with USE_DEBUG; from Christopher Layne - o Handle NULL timeouts correctly on Solaris; from Trond Norbye - o Recalculate pending events properly when reallocating event array on Solaris; from Trond Norbye - o Add Doxygen documentation to header files; from Mark Heily - o Add a evdns_set_transaction_id_fn() function to override the default - transaction ID generation code. - o Add an evutil module (with header evutil.h) to implement our standard cross-platform hacks, on the theory that somebody else would like to use them too. - o Fix signals implementation on windows. - o Fix http module on windows to close sockets properly. - o Make autogen.sh script run correctly on systems where /bin/sh isn't bash. (Patch from Trond Norbye, rewritten by Hagne Mahre and then Hannah Schroeter.) - o Skip calling gettime() in timeout_process if we are not in fact waiting for any events. (Patch from Trond Norbye) - o Make test subdirectory compile under mingw. - o Fix win32 buffer.c behavior so that it is correct for sockets (which do not like ReadFile and WriteFile). - o Make the test.sh script run unit tests for the evpoll method. - o Make the entire evdns.h header enclosed in "extern C" as appropriate. - o Fix implementation of strsep on platforms that lack it - o Fix implementation of getaddrinfo on platforms that lack it; mainly, this will make Windows http.c work better. Original patch by Lubomir Marinov. - o Fix evport implementation: port_disassociate called on unassociated events resulting in bogus errors; more efficient memory management; from Trond Norbye and Prakash Sangappa - o support for hooks on rpc input and output; can be used to implement rpc independent processing such as compression or authentication. - o use a min heap instead of a red-black tree for timeouts; as a result finding the min is a O(1) operation now; from Maxim Yegorushkin - o associate an event base with an rpc pool - o added two additional libraries: libevent_core and libevent_extra in addition to the regular libevent. libevent_core contains only the event core whereas libevent_extra contains dns, http and rpc support - o Begin using libtool's library versioning support correctly. If we don't mess up, this will more or less guarantee binaries linked against old versions of libevent continue working when we make changes to libevent that do not break backward compatibility. - o Fix evhttp.h compilation when TAILQ_ENTRY is not defined. - o Small code cleanups in epoll_dispatch(). - o Increase the maximum number of addresses read from a packet in evdns to 32. - o Remove support for the rtsig method: it hasn't compiled for a while, and nobody seems to miss it very much. Let us know if there's a good reason to put it back in. - o Rename the "class" field in evdns_server_request to dns_question_class, so that it won't break compilation under C++. Use a macro so that old code won't break. Mark the macro as deprecated. - o Fix DNS unit tests so that having a DNS server with broken IPv6 support is no longer cause for aborting the unit tests. - o Make event_base_free() succeed even if there are pending non-internal events on a base. This may still leak memory and fds, but at least it no longer crashes. - o Post-process the config.h file into a new, installed event-config.h file that we can install, and whose macros will be safe to include in header files. - o Remove the long-deprecated acconfig.h file. - o Do not require #include before #include . - o Add new evutil_timer* functions to wrap (or replace) the regular timeval manipulation functions. - o Fix many build issues when using the Microsoft C compiler. - o Remove a bash-ism in autogen.sh - o When calling event_del on a signal, restore the signal handler's previous value rather than setting it to SIG_DFL. Patch from Christopher Layne. - o Make the logic for active events work better with internal events; patch from Christopher Layne. - o We do not need to specially remove a timeout before calling event_del; patch from Christopher Layne. diff --git a/ChangeLog-1.4 b/ChangeLog-1.4 new file mode 100644 index 0000000..166d308 --- /dev/null +++ b/ChangeLog-1.4 @@ -0,0 +1,231 @@ +Changes in 1.4.14b-stable + o Set the VERSION_INFO correctly for 1.4.14 + +Changes in 1.4.14-stable + o Add a .gitignore file for the 1.4 branch.

(4faeaea) + + + +Changes in 2.0.3-alpha (20 Nov 2009): + o Add a new code to support SSL/TLS on bufferevents, using the OpenSSL library (where available). + o Fix a bug where we didn't allocate enough memory in event_get_supported_methods(). + o Avoid segfault during failed allocation of locked evdns_base. (Found by Rocco Carbone.) + o Export new evutil_ascii_* functions to perform locale-independent character type operations. + o Try to compile better with MSVC: patches from Brodie Thiesfield + o New evconnlistener_get_fd function to expose a listener's associated socket. + o Expose an ev_socklen_t type for consistent use across platforms. + o Make bufferevent_socket_connect() work when the original fd was -1. + o Fix a bug in bufferevent_socket_connect() when the connection succeeds too quickly. + o Export an evutil_sockaddr_cmp() to compare to sockaddr objects for equality. + o Add a bufferevent_get_enabled() to tell what a bufferevent has been configured to do. + o Add an evbuffer_search_eol() function to locate the end of a line nondestructively. + o Add an evbuffer_search_range() function to search a bounded range of a buffer. + o Fix a rare crash bug in evdns. + o Have bufferevent_socket_connect() with no arguments put a bufferevent into connecting mode. + o Support sendfile on Solaris: patch from Caitlin Mercer. + o New functions to explicitly reference a socket used by an evhttp object. Patches from David Reiss. + o When we send a BEV_EVENT_CONNECTED to indicate connected status, we no longer invoke the write callback as well unless we actually wrote data too. + o If the kernel tells us that there are a negative number of bytes to read from a socket, do not believe it. Fixes bug 2841177; found by Alexander Pronchenkov. + o Do not detect whether we have monotonic clock support every time a new event base is created: instead do it only once. Patch taken from Chromium. + o Do not allocate the maximum event queue for the epoll backend at startup. Instead, start out accepting 32 events at a time, and double the queue's size when it seems that the OS is generating events faster than we're requesting them. Saves up to 374K per epoll-based event_base. Resolves bug 2839240. + o Treat an event with a negative fd as valid but untriggerable by Libevent. This is useful for applications that want to manually activate events. + o Fix compilation on Android, which forgot to define fd_mask in its sys/select.h + o Do not drop data from evbuffer when out of memory; reported by Jacek Masiulaniec + o New event_base_got_exit() and event_base_got_break() functions to tell whether an event loop exited because of an event_base_loopexit() or an event_base_loopbreak(). Patch from Ka-Hing Cheung. + o When adding or deleting an event from a non-main thread, only wake up the main thread when its behavior actually needs to change. + o Fix some bugs when using the old evdns interfaces to initialize the evdns module. + o Detect errors during bufferevent_connect(). Patch from Christopher Davis. + o Fix compilation for listener.h for C++ - missing extern "C". Patch from Ferenc Szalai. + o Make the event_base_loop() family of functions respect thread-safety better. This should clear up a few hard-to-debug race conditions. + o Fix a bug when using a specialized memory allocator on win32. + o Have the win32 select() backend label TCP-socket-connected events as EV_WRITE, not EV_READ. This should bring it in line with the other backends, and improve portability. Patch from Christopher Davis. + o Stop using enums as arguments or return values when what we mean is a bitfield of enum values. C++ doesn't believe that you can OR two enum values together and get another enum, and C++ takes its typing seriously. Patch from Christopher Davis. + o Add an API to replace all fatal calls to exit() with a user-provided panic function. + o Replace all assert() calls with a variant that is aware of the user-provided logging and panic functions. + o Add a return value to event_assign so that it can fail rather than asserting when the user gives it bad input. event_set still dies on bad input. + o The event_base_new() and event_base_new_with_config() functions now never call exit() on failure. For backward "compatibility", event_init() still does, but more consistently. + o Remove compat/sys/_time.h. It interfered with system headers on HPUX, and its functionality has been subsumed by event2/util.h and util-internal.h. + o Add a new bufferevent_socket_connect_hostname() to encapsulate the resolve-then-connect operation. + o Build kqueue.c correctly on GNU/kFreeBSD platforms. Patch pulled upstream from Debian. + o Alternative queue-based timeout algorithm for programs that use a large number of timeouts with the same value. + o New event_base_config option to disable the timeval cache entirely. + o Make EV_PERSIST timeouts more accurate: schedule the next event based on the scheduled time of the previous event, not based on the current time. + o Allow http.c to handle cases where getaddrinfo returns an IPv6 address. Patch from Ryan Phillips. + o Fix a problem with excessive memory allocation when using multiple event priorities. + o Default to using arc4random for DNS transaction IDs on systems that have it; from OpenBSD. + o Never check the environment when we're running setuid or setgid; from OpenBSD. + o Options passed to evdns_set_option() no longer need to end with a colon. + o Add an evutil_getaddrinfo() function to clone getaddrinfo on platforms that don't have it. + o Add an evdns_getaddrinfo() function to provide a nonblocking getaddrinfo using evdns, so programs can perform useful hostname lookup. + o Finally expose the IOCP-based bufferevent backend. It passes its unit tests, but probably still has some bugs remaining. Code by Nick Mathewson and Christopher Davis. + o Numerous other bugfixes. + o On FreeBSD and other OSes, connect can return ECONREFUSED immediately; instead of failing the function call, pretend with faileld in the callback. + o Fix a race condition in the pthreads test case; found by Nick Mathewson + o Remove most calls to event_err() in http and deal with memory errors instead + + + +Changes in 2.0.2-alpha (25 Jul 2009): + o Add a new flag to bufferevents to make all callbacks automatically deferred. + o Make evdns functionality locked, and automatically defer dns callbacks. + o Fix a possible free(NULL) when freeing an event_base with no signals. + o Add a flag to disable checking environment varibles when making an event_base + o Disallow setting less than 1 priority. + o Fix a bug when removing a timeout from the heap. [Patch from Marko Kreen] + o Use signal.h, not sys/signal.h. [Patch from mmadia] + o Try harder to build with certain older c99 compilers. + o Make sure that an event_config's flags field is always initialized to 0. [Bug report from Victor Goya] + o Avoid data corruption when reading data entirely into the second-to-last chain of an evbuffer. [Bug report from Victor Goya] + o Make sendfile work on FreeBSD + o Do not use vararg macros for accessing evrpc structures; this is not backwards compatible, but we did not promise any backwards compatibility for the rpc code. + o Actually define the event_config_set_flag() function. + o Try harder to compile with Visual C++. + o Move event_set() and its allies to event2/event_compat.h where they belong. + o Remove the event_gotsig code, which has long been deprecated and unused. + o Add an event_get_base() function to return the base assigned to an event. + o New function to automate connecting on a socket-based bufferevent. + o New functions to automate listening for incoming TCP connections. + o Do case-insensitive checks with a locale-independent comparison function. + o Rename the evbuffercb and everrorcb callbacks to bufferevent_data_cb and bufferevent_event_cb respectively. The old names are available in bufferevent_compat.h. + o Rename the EVBUFFER_* codes used by bufferevent event callbacks to BEV_EVENT_*, to avoid namespace collision with evbuffer flags. The old names are available in bufferevent_compat.h. + o Move the EVBUFFER_INPUT and EVBUFFER_OUTPUT macros to bufferevent_compat.h + o Add a bufferevent_getfd() function to mirror bufferevent_setfd() + o Make bufferevent_setfd() return an error code if the operation is not successful. + o Shave 22 bytes off struct event on 32-bit platforms by shrinking and re-ordering fields. The savings on 64-bit platforms is likely higher. + o Cap the maximum number of priorities at 256. + o Change the semantics of evbuffer_cb_set_flags() to be set-flag only; add a new evbuffer_cb_clear_flags() to remove set flags. + o Change the interface of evbuffer_add_reference so that the cleanup callback gets more information + o Revise the new evbuffer_reserve_space/evbuffer_commit_space() interfaces so that you can use them without causing extraneous copies or leaving gaps in the evbuffer. + o Add a new evbuffer_peek() interface to inspect data in an evbuffer without removing it. + o Fix a deadlock when suspending reads in a bufferevent due to a full buffer. (Spotted by Joachim Bauch.) + o Fix a memory error when freeing a thread-enabled event base with registered events. (Spotted by Joachim Bauch.) + o Try to contain degree of failure when running on a win32 version so heavily firewalled that we can't fake a socketpair. + o Activate fd events in a pseudorandom order with O(N) backends, so that we don't systematically favor low fds (select) or earlier-added fds (poll, win32). + o Replace some read()/write() instances with send()/recv() to work properly on win32. + o Set truncated flag correctly in evdns server replies. + o Raise RpcGenError in event_rpcgen.py; from jmanison and Zack Weinberg + o Fix preamble of rpcgen-generated files to rely on event2 includes; based on work by jmansion; patch from Zack Weinberg. + o Allow specifying the output filename for rpcgen; based on work by jmansion; patch from Zack Weinberg. + o Allow C identifiers as struct names; allow multiple comments in .rpc files; from Zack Weinberg + o Mitigate a race condition when using socket bufferevents in multiple threads. + o Use AC_SEARCH_LIBS, not AC_CHECK_LIB to avoid needless library use. + o Do not allow event_del(ev) to return while that event's callback is executing in another thread. This fixes a nasty race condition. + o event_get_supported_methods() now lists methods that have been disabled with the EVENT_NO* environment options. + o Rename encode_int[64] to evtag_encode_int[64] to avoid polluting the global namespace. The old method names are still available as macros in event2/tag_compat.h. + + + +Changes in 2.0.1-alpha (17 Apr 2009): + o free minheap on event_base_free(); from Christopher Layne + o debug cleanups in signal.c; from Christopher Layne + o provide event_base_new() that does not set the current_base global + o bufferevent_write now uses a const source argument; report from Charles Kerr + o improve documentation on event_base_loopexit; patch from Scott Lamb + o New function, event_{base_}loopbreak. Like event_loopexit, it makes an event loop stop executing and return. Unlike event_loopexit, it keeps subsequent pending events from getting executed. Patch from Scott Lamb + o Check return value of event_add in signal.c + o provide event_reinit() to reintialize an event_base after fork + o New function event_set_mem_functinons. It allows the user to give libevent replacement functions to use for memory management in place of malloc(), free(), etc. This should be generally useful for memory instrumentation, specialized allocators, and so on. + o The kqueue implementation now catches signals that are raised after event_add() is called but before the event_loop() call. This makes it match the other implementations. + o The kqueue implementation now restores original signal handlers correctly when its signal events are removed. + o Check return value of event_add in signal.c + o Add a more powerful evbuffer_readln as a replacement for evbuffer_readline. The new function handles more newline styles, and is more useful with buffers that may contain a nul characters. + o Do not mangle socket handles on 64-bit windows. + o The configure script now takes an --enable-gcc-warnigns option that turns on many optional gcc warnings. (Nick has been building with these for a while, but they might be useful to other developers.) + o move EV_PERSIST handling out of the event backends + o small improvements to evhttp documentation + o always generate Date and Content-Length headers for HTTP/1.1 replies + o set the correct event base for HTTP close events + o When building with GCC, use the "format" attribute to verify type correctness of calls to printf-like functions. + o Rewrite win32.c backend to be O(n lg n) rather than O(n^2). + o Removed obsoleted recalc code + o support for 32-bit tag numbers in rpc structures; this is wire compatible, but changes the API slightly. + o pull setters/getters out of RPC structures into a base class to which we just need to store a pointer; this reduces the memory footprint of these structures. + o prefix {encode,decode}_tag functions with evtag to avoid collisions + o fix a bug with event_rpcgen for integers + o Correctly handle DNS replies with no answers set (Fixes bug 1846282) + o add -Wstrict-aliasing to warnings and more cleanup + o removed linger from http server socket; reported by Ilya Martynov + o event_rpcgen now allows creating integer arrays + o support string arrays in event_rpcgen + o change evrpc hooking to allow pausing of RPCs; this will make it possible for the hook to do some meaning ful work; this is not backwards compatible. + o allow an http request callback to take ownership of a request structure + o allow association of meta data with RPC requests for hook processing + o associate more context for hooks to query such as the connection object + o remove pending timeouts on event_base_free() + o also check EAGAIN for Solaris' event ports; from W.C.A. Wijngaards + o devpoll and evport need reinit; tested by W.C.A Wijngaards + o event_base_get_method; from Springande Ulv + o Send CRLF after each chunk in HTTP output, for compliance with RFC2626.

This is probably a kernel defect, but we'll have to support old kernels anyway even if it gets fixed. + o Make name_from_addr() threadsafe in http.c + o Add new thread-safe interfaces to evdns functions. + o Make all event_tagging interfaces threadsafe. + o Rename internal memory management functions. + o New functions (event_assign, event_new, event_free) for use by apps that want to be safely threadsafe, or want to remain ignorant of the contents of struct event. + o introduce bufferevent_read_buffer; allows reading without memory copy. + o expose bufferevent_setwatermark via header files and fix high watermark on read + o fix a bug in buffrevent read water marks and add a test for them + o fix a bug in which bufferevent_write_buffer would not schedule a write event + o provide bufferevent_input and bufferevent_output without requiring knowledge of the structure + o introduce bufferevent_setcb and bufferevent_setfd to allow better manipulation of bufferevents + o convert evhttp_connection to use bufferevents. + o use libevent's internal timercmp on all platforms, to avoid bugs on old platforms where timercmp(a,b,<=) is buggy. + o Remove the never-exported, never-used evhttp_hostportfile function. + o Support input/output filters for bufferevents; somewhat similar to libio's model. This will allow us to implement SSL, compression, etc, transparently to users of bufferevents such as the http layer. + o allow connections to be removed from an rpc pool + o add new evtimer_assign, signal_assign, evtimer_new, and signal_new functions to manipulate timer and signal events, analagous to the now-recommended event_assign and event_new + o switch internal uses of event_set over to use event_assign. + o introduce evbuffer_contiguous_space() api that tells a user how much data is available in the first buffer chain + o introduce evbuffer_reserve_space() and evbuffer_commit_space() to make processing in filters more efficient. + o reduce system calls for getting current time by caching it. + o separate signal events from io events; making the code less complex. + o support for periodic timeouts + o support for virtual HTTP hosts. + o turn event_initialized() into a function, and add function equivalents to EVENT_SIGNAL and EVENT_FD so that people don't need to include event_struct.h + o Build test directory correctly with CPPFLAGS set. + o Provide an API for retrieving the supported event mechanisms. + o event_base_new_with_config() and corresponding config APIs. + o migrate the evhttp header to event2/ but accessors are still missing. + o deprecate timeout_* event functions by moving them to event_compat.h + o Move windows gettimeofday replacement into a new evutil_gettimeofday(). + o Make configure script work on IRIX. + o provide a method for canceling ongoing http requests. + o Make vsnprintf() returns consistent on win32. + o Fix connection keep-alive behavior for HTTP/1.0 + o Fix use of freed memory in event_reinit; pointed out by Peter Postma + o constify struct timeval * where possible + o make event_get_supported_methods obey environment variables + o support for edge-triggered events on epoll and kqueue backends: patch from Valery Kholodkov + o support for selecting event backends by their features, and for querying the features of a backend. + o change failing behavior of event_base_new_with_config: if a config is provided and no backend is selected, return NULL instead of aborting. + o deliver partial data to request callbacks when chunked callback is set even if there is no chunking on the http level; allows cancelation of requests from within the chunked callback; from Scott Lamb. + o allow min_heap_erase to be called on removed members; from liusifan. + o Rename INPUT and OUTPUT to EVRPC_INPUT and EVRPC_OUTPUT. Retain INPUT/OUTPUT aliases on on-win32 platforms for backwards compatibility. + o Do not use SO_REUSEADDR when connecting + o Support 64-bit integers in RPC structs + o Correct handling of trailing headers in chunked replies; from Scott Lamb. + o Support multi-line HTTP headers; based on a patch from Moshe Litvin + o Reject negative Content-Length headers; anonymous bug report + o Detect CLOCK_MONOTONIC at runtime for evdns; anonymous bug report + o Various HTTP correctness fixes from Scott Lamb + o Fix a bug where deleting signals with the kqueue backend would cause subsequent adds to fail + o Support multiple events listening on the same signal; make signals regular events that go on the same event queue; problem report by Alexander Drozdov. + o Fix a problem with epoll() and reinit; problem report by Alexander Drozdov. + o Fix off-by-one errors in devpoll; from Ian Bell + o Make event_add not change any state if it fails; reported by Ian Bell. + o Fix a bug where headers arriving in multiple packets were not parsed; fix from Jiang Hong; test by me. + o Match the query in DNS replies to the query in the request; from Vsevolod Stakhov. + o Add new utility functions to correctly observe and log winsock errors. + o Do not remove Accept-Encoding header + o Clear the timer cache on entering the event loop; reported by Victor Chang + o Only bind the socket on connect when a local address has been provided; reported by Alejo Sanchez + o Allow setting of local port for evhttp connections to support millions of connections from a single system; from Richard Jones. + o Clear the timer cache when leaving the event loop; reported by Robin Haberkorn + o Fix a typo in setting the global event base; reported by lance. + o Set the 0x20 bit on outgoing alphabetic characters in DNS requests randomly, and insist on a match in replies. This helps resist DNS poisoning attacks. + o Make the http connection close detection work properly with bufferevents and fix a potential memory leak associated with it. + o Restructure the event backends so that they do not need to keep track of events themselves, as a side effect multiple events can use the same fd or signal. + o Add generic implementations for parsing and emiting IPv6 addresses on platforms that do not have inet_ntop and/or inet_pton. + o Allow DNS servers that have IPv6 addresses. + o Add an evbuffer_write_atmost() function to write a limited number of bytes to an fd. + o Refactor internal notify-main-thread logic to prefer eventfd to pipe, then pipe to socketpair, and only use socketpairs as a last resort. + o Try harder to pack all evbuffer reads into as few chains as possible, using readv/WSARecv as appropriate. + o New evthread_use_windows_threads() and evthread_use_pthreads() functions to set up the evthread callbacks with reasonable defaults. + o Change the semantics of timeouts in conjunction with EV_PERSIST; timeouts in that case will now repeat until deleted. + o sendfile, mmap and memory reference support for evbuffers. + o New evutil_make_listen_socket_reuseable() to abstract SO_REUSEADDR. + o New bind-to option to allow DNS clients to bind to an arbitrary port for outgoing requests. + o evbuffers can now be "frozen" to prevent operations at one or both ends. + o Bufferevents now notice external attempts to add data to an inbuf or remove it from an outbuf, and stop them. + o Fix parsing of queries where the encoded queries contained \r, \n or + + o Do not allow internal events to starve lower-priority events. + diff --git a/Doxyfile b/Doxyfile index 5d3865e..d9d6603 100644 --- a/Doxyfile +++ b/Doxyfile @@ -239,7 +239,7 @@ INCLUDE_FILE_PATTERNS = # undefined via #undef or recursively expanded use the := operator # instead of the = operator. -PREDEFINED = TAILQ_ENTRY RB_ENTRY _EVENT_DEFINED_TQENTRY _EVENT_IN_DOXYGEN +PREDEFINED = TAILQ_ENTRY RB_ENTRY EVENT_DEFINED_TQENTRY_ EVENT_IN_DOXYGEN_ # If the MACRO_EXPANSION and EXPAND_ONLY_PREDEF tags are set to YES then # this tag can be used to specify a list of macro names that should be expanded. diff --git a/LICENSE b/LICENSE index 70d76b3..402ca50 100644 --- a/LICENSE +++ b/LICENSE @@ -72,3 +72,28 @@ The arc4module is available under the following, sometimes called the ACTION OF CONTRACT, NEGLIGENCE OR OTHER TORTIOUS ACTION, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE. +============================== + +The Windows timer code is based on code from libutp, which is +distributed under this license, sometimes called the "MIT" license. + + +Copyright (c) 2010 BitTorrent, Inc. + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Where to get help + + Try looking at the other documentation too. All of the header files + have documentation in the doxygen format; this gets turned into nice + HTML and linked to from the libevent.org website. + + There is a work-in-progress book with reference manual at + http://www.wangafu.net/~nickm/libevent-book/ . + + You can ask questions on the #libevent IRC channel at irc.oftc.net or + on the mailing list at libevent-users@freehaven.net. The mailing list + is subscribers-only, so you will need to subscribe before you post. + +0.3. Compatibility + + Our source-compatibility policy is that correct code (that is to say, + code that uses public interfaces of Libevent and relies only on their + documented behavior) should have forward source compatibility: any + such code that worked with a previous version of Libevent should work + with this version too. + + We don't try to do binary compatibility except within stable release + series, so binaries linked against any version of Libevent 2.0 will + probably need to be recompiled against Libevent 2.1.4-alpha if you + want to use it. It is probable that we'll break binary compatibility + again before Libevent 2.1 is stable. + +1. New APIs and features + +1.1. New ways to build libevent + + We now provide an --enable-gcc-hardening configure option to turn on + GCC features designed for increased code security. + + There is also an --enable-silent-rules configure option to make + compilation run more quietly with automake 1.11 or later. + + You no longer need to use the --enable-gcc-warnings option to turn on + all of the GCC warnings that Libevent uses. The only change from + using that option now is to turn warnings into errors. + + For IDE users, files that are not supposed to be built are now + surrounded with appropriate #ifdef lines to keep your IDE from getting + upset. + + There is now an alternative cmake-based build process; cmake users + should see the relevant sections in the README. + + +1.2. New functions for events and the event loop + + If you're running Libevent with multiple event priorities, you might + want to make sure that Libevent checks for new events frequently, so + that time-consuming or numerous low-priority events don't keep it from + checking for new high-priority events. You can now use the + event_config_set_max_dispatch_interval() interface to ensure that the + loop checks for new events either every N microseconds, every M + callbacks, or both. + + When configuring an event base, you can now choose whether you want + timers to be more efficient, or more precise. (This only has effect + on Linux for now.) Timers are efficient by default: to select more + precise timers, use the EVENT_BASE_FLAG_PRECISE_TIMER flag when + constructing the event_config, or set the EVENT_PRECISE_TIMER + environment variable to a non-empty string. + + There is an EVLOOP_NO_EXIT_ON_EMPTY flag that tells event_base_loop() + to keep looping even when there are no pending events. (Ordinarily, + event_base_loop() will exit as soon as no events are pending.) + + Past versions of Libevent have been annoying to use with some + memory-leak-checking tools, because Libevent allocated some global + singletons but provided no means to free them. There is now a + function, libevent_global_shutdown(), that you can use to free all + globally held resources before exiting, so that your leak-check tools + don't complain. (Note: this function doesn't free non-global things + like events, bufferevents, and so on; and it doesn't free anything + that wouldn't otherwise get cleaned up by the operating system when + your process exit()s. If you aren't using a leak-checking tool, there + is not much reason to call libevent_global_shutdown().) + + There is a new event_base_get_npriorities() function to return the + number of priorities set in the event base. + + Libevent 2.0 added an event_new() function to construct a new struct + event on the heap. Unfortunately, with event_new(), there was no + equivalent for: + + struct event ev; + event_assign(&ev, base, fd, EV_READ, callback, &ev); + + In other words, there was no easy way for event_new() to set up an + event so that the event itself would be its callback argument. + Libevent 2.1 lets you do this by passing "event_self_cbarg()" as the + callback argument: + + struct event *evp; + evp = event_new(base, fd, EV_READ, callback, + event_self_cbarg()); + + There's also a new event_base_get_running_event() function you can + call from within a Libevent callback to get a pointer to the current + event. This should never be strictly necessary, but it's sometimes + convenient. + + The event_base_once() function used to leak some memory if the event + that it added was never actually triggered. Now, its memory is + tracked in the event_base and freed when the event_base is freed. + Note however that Libevent doesn't know how to free any information + passed as the callback argument to event_base_once is still something + you'll might need a way to de-allocate yourself. + + There is an event_get_priority() function to return an event's + priority. + + By analogy to event_base_loopbreak(), there is now an + event_base_loopcontinue() that tells Libevent to stop processing + active event callbacks, and re-scan for new events right away. + + There's a function, event_base_foreach_event(), that can iterate over + every event currently pending or active on an event base, and invoke a + user-supplied callback on each. The callback must not alter the events + or add or remove anything to the event base. + + We now have an event_remove_timer() function to remove the timeout on + an event while leaving its socket and/or signal triggers unchanged. + (If we were designing the API from scratch, this would be the behavior + of "event_add(ev, NULL)" on an already-added event with a timeout. But + that's a no-op in past versions of Libevent, and we don't want to + break compatibility.) + + You can use the new event_base_get_num_events() function to find the + number of events active or pending on an event_base. To find the + largest number of events that there have been since the last call, use + event_base_get_max_events(). + + You can now activate all the events waiting for a given fd or signal + using the event_base_active_by_fd() and event_base_active_by_signal() + APIs. + + On backends that support it (currently epoll), there is now an + EV_CLOSED flag that programs can use to detect when a socket has + closed without having to read all the bytes until receiving an EOF. + +1.3. Event finalization + +1.3.1. Why event finalization? + + Libevent 2.1 now supports an API for safely "finalizing" events that + might be running in multiple threads, and provides a way to slightly + change the semantics of event_del() to prevent deadlocks in + multithreaded programs. + + To motivate this feature, consider the following code, in the context + of a mulithreaded Libevent application: + + struct connection *conn = event_get_callback_arg(ev); + event_del(ev); + connection_free(conn); + + Suppose that the event's callback might be running in another thread, + and using the value of "conn" concurrently. We wouldn't want to + execute the connection_free() call until "conn" is no longer in use. + How can we make this code safe? + + Libevent 2.0 answered that question by saying that the event_del() + call should block if the event's callback is running in another + thread. That way, we can be sure that event_del() has canceled the + callback (if the callback hadn't started running yet), or has waited + for the callback to finish. + + But now suppose that the data structure is protected by a lock, and we + have the following code: + + void check_disable(struct connection *connection) { + lock(connection); + if (should_stop_reading(connection)) + event_del(connection->read_event); + unlock(connection); + } + + What happens when we call check_disable() from a callback and from + another thread? Let's say that the other thread gets the lock + first. If it decides to call event_del(), it will wait for the + callback to finish. But meanwhile, the callback will be waiting for + the lock on the connection. Since each threads is waiting for the + other one to release a resource, the program will deadlock. + + This bug showed up in multithreaded bufferevent programs in 2.1, + particularly when freeing bufferevents. (For more information, see + the "Deadlock when calling bufferevent_free from an other thread" + thread on libevent-users starting on 6 August 2012 and running through + February of 2013. You might also like to read my earlier writeup at + http://archives.seul.org/libevent/users/Feb-2012/msg00053.html and + the ensuing discussion.) + +1.3.2. The EV_FINALIZE flag and avoiding deadlock + + To prevent the deadlock condition described above, Libevent + 2.1.3-alpha adds a new flag, "EV_FINALIZE". You can pass it to + event_new() and event_assign() along with EV_READ, EV_WRITE, and the + other event flags. + + When an event is constructed with the EV_FINALIZE flag, event_del() + will not block on that event, even when the event's callback is + running in another thread. By using EV_FINALIZE, you are therefore + promising not to use the "event_del(ev); free(event_get_callback_arg(ev));" + pattern, but rather to use one of the finalization functions below to + clean up the event. + + EV_FINALIZE has no effect on a single-threaded program, or on a + program where events are only used from one thread. + + + There are also two new variants of event_del() that you can use for + more fine-grained control: + event_del_noblock(ev) + event_del_block(ev) + The event_del_noblock() function will never block, even if the event + callback is running in another thread and doesn't have the EV_FINALIZE + flag. The event_del_block() function will _always_ block if the event + callback is running in another thread, even if the event _does_ have + the EV_FINALIZE flag. + + [A future version of Libevent may have a way to make the EV_FINALIZE + flag the default.] + +1.3.3. Safely finalizing events + + To safely tear down an event that may be running, Libevent 2.1.3-alpha + introduces event_finalize() and event_free_finalize(). You call them + on an event, and provide a finalizer callback to be run on the event + and its callback argument once the event is definitely no longer + running. + + With event_free_finalize(), the event is also freed once the finalizer + callback has been invoked. + + A finalized event cannot be re-added or activated. The finalizer + callback must not add events, activate events, or attempt to + "resucitate" the event being finalized in any way. + + If any finalizer callbacks are pending as the event_base is being + freed, they will be invoked. You can override this behavior with the + new function event_base_free_nofinalize(). + +1.4. New debugging features + + You can now turn on debug logs at runtime using a new function, + event_enable_debug_logging(). + + The event_enable_lock_debugging() function is now spelled correctly. + You can still use the old "event_enable_lock_debuging" name, though, + so your old programs shouldnt' break. + + There's also been some work done to try to make the debugging logs + more generally useful. + +1.5. New evbuffer functions + + In Libevent 2.0, we introduced evbuffer_add_file() to add an entire + file's contents to an evbuffer, and then send them using sendfile() or + mmap() as appropriate. This API had some drawbacks, however. + Notably, it created one mapping or fd for every instance of the same + file added to any evbuffer. Also, adding a file to an evbuffer could + make that buffer unusable with SSL bufferevents, filtering + bufferevents, and any code that tried to read the contents of the + evbuffer. + + Libevent 2.1 adds a new evbuffer_file_segment API to solve these + problems. Now, you can use evbuffer_file_segment_new() to construct a + file-segment object, and evbuffer_add_file_segment() to insert it (or + part of it) into an evbuffer. These segments avoid creating redundant + maps or fds. Better still, the code is smart enough (when the OS + supports sendfile) to map the file when that's necessary, and use + sendfile() otherwise. + + File segments can receive callback functions that are invoked when the + file segments are freed. + + The evbuffer_ptr interface has been extended so that an evbuffer_ptr + can now yield a point just after the end of the buffer. This makes + many algorithms simpler to implement. + + There's a new evbuffer_add_buffer() interface that you can use to add + one buffer to another nondestructively. When you say + evbuffer_add_buffer_reference(outbuf, inbuf), outbuf now contains a + reference to the contents of inbuf. + + To aid in adding data in bulk while minimizing evbuffer calls, there + is an evbuffer_add_iovec() function. + + There's a new evbuffer_copyout_from() variant function to enable + copying data nondestructively from the middle of a buffer. + + evbuffer_readln() now supports an EVBUFFER_EOL_NUL argument to fetch + NUL-terminated strings from buffers. + + There's a new evbuffer_set_flags()/evbuffer_clear_flags() that you can use to + set EVBUFFER_FLAG_DRAINS_TO_FD. + +1.6. New functions and features: bufferevents + + You can now use the bufferevent_getcb() function to find out a + bufferevent's callbacks. Previously, there was no supported way to do + that. + + The largest chunk readable or writeable in a single bufferevent + callback is no longer hardcoded; it's now configurable with + the new functions bufferevent_set_max_single_read() and + bufferevent_set_max_single_write(). + + For consistency, OpenSSL bufferevents now make sure to always set one + of BEV_EVENT_READING or BEV_EVENT_WRITING when invoking an event + callback. + + Calling bufferevent_set_timeouts(bev, NULL, NULL) now removes the + timeouts from socket and ssl bufferevents correctly. + + You can find the priority at which a bufferevent runs with + bufferevent_get_priority(). + + The function bufferevent_get_token_bucket_cfg() can retrieve the + rate-limit settings for a bufferevent; bufferevent_getwatermark() can + return a bufferevent's current watermark settings. + + You can manually trigger a bufferevent's callbacks via + bufferevent_trigger() and bufferevent_trigger_event(). + + Also you can manually increment/decrement reference for bufferevent with + bufferevent_incref()/bufferevent_decref(), it is useful in situations where a + user may reference the bufferevent somewhere else. + + Now bufferevent_openssl supports "dirty" shutdown (when the peer closes the + TCP connection before closing the SSL channel), see + bufferevent_openssl_get_allow_dirty_shutdown() and + bufferevent_openssl_set_allow_dirty_shutdown(). + + And also libevent supports openssl 1.1. + +1.7. New functions and features: evdns + + The previous evdns interface used an "open a test UDP socket" trick in + order to detect IPv6 support. This was a hack, since it would + sometimes badly confuse people's firewall software, even though no + packets were sent. The current evdns interface-detection code uses + the appropriate OS functions to see which interfaces are configured. + + The evdns_base_new() function now has multiple possible values for its + second (flags) argument. Using 1 and 0 have their old meanings, though the + 1 flag now has a symbolic name of EVDNS_BASE_INITIALIZE_NAMESERVERS. + A second flag is now supported too: the EVDNS_BASE_DISABLE_WHEN_INACTIVE + flag, which tells the evdns_base that it should not prevent Libevent from + exiting while it has no DNS requests in progress. + + There is a new evdns_base_clear_host_addresses() function to remove + all the /etc/hosts addresses registered with an evdns instance. + + Also there is evdns_base_get_nameserver_addr() for retrieve the address of + the 'idx'th configured nameserver. + +1.8. New functions and features: evconnlistener + + Libevent 2.1 adds the following evconnlistener flags: + + LEV_OPT_DEFERRED_ACCEPT -- Tells the OS that it doesn't need to + report sockets as having arrived until the initiator has sent some + data too. This can greatly improve performance with protocols like + HTTP where the client always speaks first. On operating systems + that don't support this functionality, this option has no effect. + + LEV_OPT_REUSEABLE_PORT -- Indicates that we ask to allow multiple servers + to bind to the same port if they each set the option Ionly on Linux and + >=3.9) + + LEV_OPT_DISABLED -- Creates an evconnlistener in the disabled (not + listening) state. + + Libevent 2.1 changes the behavior of the LEV_OPT_CLOSE_ON_EXEC + flag. Previously, it would apply to the listener sockets, but not to + the accepted sockets themselves. That's almost never what you want. + Now, it applies both to the listener and the accepted sockets. + +1.9. New functions and features: evhttp + + ********************************************************************** + NOTE: The evhttp module will eventually be deprecated in favor of Mark + Ellzey's libevhtp library. Don't worry -- this won't happen until + libevhtp provides every feature that evhttp does, and provides a + compatible interface that applications can use to migrate. + ********************************************************************** + + Previously, you could only set evhttp timeouts in increments of one + second. Now, you can use evhttp_set_timeout_tv() and + evhttp_connection_set_timeout_tv() to configure + microsecond-granularity timeouts. + + Also there is evhttp_connection_set_initial_retry_tv() to change initial + retry timeout. + + There are a new pair of functions: evhttp_set_bevcb() and + evhttp_connection_base_bufferevent_new(), that you can use to + configure which bufferevents will be used for incoming and outgoing + http connections respectively. These functions, combined with SSL + bufferevents, should enable HTTPS support. + + There's a new evhttp_foreach_bound_socket() function to iterate over + every listener on an evhttp object. + + Whitespace between lines in headers is now folded into a single space; + whitespace at the end of a header is now removed. + + The socket errno value is now preserved when invoking an http error + callback. + + There's a new kind of request callback for errors; you can set it with + evhttp_request_set_error_cb(). It gets called when there's a request error, + and actually reports the error code and lets you figure out which request + failed. + + You can navigate from an evhttp_connection back to its evhttp with the + new evhttp_connection_get_server() function. + + You can override the default HTTP Content-Type with the new + evhttp_set_default_content_type() function + + There's a new evhttp_connection_get_addr() API to return the peer + address of an evhttp_connection. + + The new evhttp_send_reply_chunk_with_cb() is a variant of + evhttp_send_reply_chunk() with a callback to be invoked when the + chunk is sent. + + The evhttp_request_set_header_cb() facility adds a callback to be + invoked while parsing headers. + + The evhttp_request_set_on_complete_cb() facility adds a callback to be + invoked on request completion. + + You can add linger-close for http server by passing + EVHTTP_SERVER_LINGERING_CLOSE to evhttp_set_flags(), with this flag server + read all the clients body, and only after this respond with an error if the + clients body exceed max_body_size (since some clients cannot read response + otherwise). + + The evhttp_connection_set_family() can bypass family hint to evdns. + + There are some flags available for connections, which can be installed with + evhttp_connection_set_flags(): + - EVHTTP_CON_REUSE_CONNECTED_ADDR -- reuse connection address on retry (avoid + extra DNS request). + - EVHTTP_CON_READ_ON_WRITE_ERROR - try read error, since server may already + close the connection. + + The evhttp_connection_free_on_completion() can be used to tell libevent to + free the connection object after the last request has completed or failed. + + There is evhttp_request_get_response_code_line() if + evhttp_request_get_response_code() is not enough for you. + + There are *evhttp_uri_parse_with_flags() that accepts + EVHTTP_URI_NONCONFORMANT to tolerate URIs that do not conform to RFC3986. + The evhttp_uri_set_flags() can changes the flags on URI. + +1.10. New functions and features: evutil + + There's a function "evutil_secure_rng_set_urandom_device_file()" that + you can use to override the default file that Libevent uses to seed + its (sort-of) secure RNG. + + The evutil_date_rfc1123() returns date in RFC1123 + + There are new API to work with monotonic timer -- monotonic time is + guaranteed never to run in reverse, but is not necessarily epoch-based. Use + it to make reliable measurements of elapsed time between events even when the + system time may be changed: + - evutil_monotonic_timer_new()/evutil_monotonic_timer_free() + - evutil_configure_monotonic_time() + - evutil_gettime_monotonic() + + Use evutil_make_listen_socket_reuseable_port() to set SO_REUSEPORT (linux >= + 3.9) + + The evutil_make_tcp_listen_socket_deferred() can make a tcp listener socket + defer accept()s until there is data to read (TCP_DEFER_ACCEPT). + +2. Cross-platform performance improvements + +2.1. Better data structures + + We replaced several users of the sys/queue.h "TAILQ" data structure + with the "LIST" data structure. Because this data type doesn't + require FIFO access, it requires fewer pointer checks and + manipulations to keep it in line. + + All previous versions of Libevent have kept every pending (added) + event in an "eventqueue" data structure. Starting in Libevent 2.0, + however, this structure became redundant: every pending timeout event + is stored in the timeout heap or in one of the common_timeout queues, + and every pending fd or signal event is stored in an evmap. Libevent + 2.1 removes this data structure, and thereby saves all of the code + that we'd been using to keep it updated. + +2.2. Faster activations and timeouts + + It's a common pattern in older code to use event_base_once() with a + 0-second timeout to ensure that a callback will get run 'as soon as + possible' in the current iteration of the Libevent loop. We optimize + this case by calling event_active() directly, and bypassing the + timeout pool. (People who are using this pattern should also consider + using event_active() themselves.) + + Libevent 2.0 would wake up a polling event loop whenever the first + timeout in the event loop was adjusted--whether it had become earlier + or later. We now only notify the event loop when a change causes the + expiration time to become _sooner_ than it would have been otherwise. + + The timeout heap code is now optimized to perform fewer comparisons + and shifts when changing or removing a timeout. + + Instead of checking for a wall-clock time jump every time we call + clock_gettime(), we now check only every 5 seconds. This should save + a huge number of gettimeofday() calls. + +2.3. Microoptimizations + + Internal event list maintainance no longer use the antipattern where + we have one function with multiple totally independent behaviors + depending on an argument: + #define OP1 1 + #define OP2 2 + #define OP3 3 + void func(int operation, struct event *ev) { + switch (op) { + ... + } + } + Instead, these functions are now split into separate functions for + each operation: + void func_op1(struct event *ev) { ... } + void func_op2(struct event *ev) { ... } + void func_op3(struct event *ev) { ... } + + This produces better code generation and inlining decisions on some + compilers, and makes the code easier to read and check. + +2.4. Evbuffer performance improvements + + The EVBUFFER_EOL_CRLF line-ending type is now much faster, thanks to + smart optimizations. + +2.5. HTTP performance improvements + + o Performance tweak to evhttp_parse_request_line. (aee1a97 Mark Ellzey) + o Add missing break to evhttp_parse_request_line (0fcc536) + +2.6. Coarse timers by default on Linux + + Due to limitations of the epoll interface, Libevent programs using epoll + have not previously been able to wait for timeouts with accuracy smaller + than 1 millisecond. But Libevent had been using CLOCK_MONOTONIC for + timekeeping on Linux, which is needlessly expensive: CLOCK_MONOTONIC_COARSE + has approximately the resolution corresponding to epoll, and is much faster + to invoke than CLOCK_MONOTONIC. + + To disable coarse timers, and get a more plausible precision, use the + new EVENT_BASE_FLAG_PRECISE_TIMER flag when setting up your event base. + +3. Backend/OS-specific improvements + +3.1. Linux-specific improvements + + The logic for deciding which arguements to use with epoll_ctl() is now + a table-driven lookup, rather than the previous pile of cascading + branches. This should minimize epoll_ctl() calls and make the epoll + code run a little faster on change-heavy loads. + + Libevent now takes advantage of Linux's support for enhanced APIs + (e.g., SOCK_CLOEXEC, SOCK_NONBLOCK, accept4, pipe2) that allow us to + simultaneously create a socket, make it nonblocking, and make it + close-on-exec. This should save syscalls throughout our codebase, and + avoid race-conditions if an exec() occurs after a socket is socket is + created but before we can make it close-on-execute on it. + +3.2. Windows-specific improvements + + We now use GetSystemTimeAsFileTime to implement gettimeofday. It's + significantly faster and more accurate than our old ftime()-based approach. + +3.3. Improvements in the solaris evport backend. + + The evport backend has been updated to use many of the infrastructure + improvements from Libevent 2.0. Notably, it keeps track of per-fd + information using the evmap infrastructure, and removes a number of + linear scans over recently-added events. This last change makes it + efficient to receive many more events per evport_getn() call, thereby + reducing evport overhead in general. + +3.4. OSX backend improvements + + The OSX select backend doesn't like to have more than a certain number + of fds set unless an "unlimited select" option has been set. + Therefore, we now set it. + +3.5. Monotonic clocks on even more platforms + + Libevent previously used a monotonic clock for its internal timekeeping + only on platforms supporting the POSIX clock_gettime() interface. Now, + Libevent has support for monotonic clocks on OSX and Windows too, and a + fallback implementation for systems without monotonic clocks that will at + least keep time running forwards. + + Using monotonic timers makes Libevent more resilient to changes in the + system time, as can happen in small amounts due to clock adjustments from + NTP, or in large amounts due to users who move their system clocks all over + the timeline in order to keep nagware from nagging them. + +3.6. Faster cross-thread notification on kqueue + + When a thread other than the one in which the main event loop is + running needs to wake the thread running the main event loop, Libevent + usually writes to a socketpair in order to force the main event loop + to wake up. On Linux, we've been able to use eventfd() instead. Now + on BSD and OSX systems (any anywhere else that has kqueue with the + EVFILT_USER extension), we can use EVFILT_USER to wake up the main + thread from kqueue. This should be a tiny bit faster than the + previous approach. + +4. Infrastructure improvements + +4.1. Faster tests + + I've spent some time to try to make the unit tests run faster in + Libevent 2.1. Nearly all of this was a matter of searching slow tests + for unreasonably long timeouts, and cutting them down to reasonably + long delays, though on one or two cases I actually had to parallelize + an operation or improve an algorithm. + + On my desktop, a full "make verify" run of Libevent 2.0.18-stable + requires about 218 seconds. Libevent 2.1.1-alpha cuts this down to + about 78 seconds. + + Faster unit tests are great, since they let programmers test their + changes without losing their train of thought. + +4.2. Finicky tests are now off-by-default + + The Tinytest unit testing framework now supports optional tests, and + Libevent uses them. By default, Libevent's unit testing framework + does not run tests that require a working network, and does not run + tests that tend to fail on heavily loaded systems because of timing + issues. To re-enable all tests, run ./test/regress using the "@all" + alias. + +4.3. Modernized use of autotools + + Our autotools-based build system has been updated to build without + warnings on recent autoconf/automake versions. + + Libevent's autotools makefiles are no longer recursive. This allows + make to use the maximum possible parallelism to do the minimally + necessary amount of work. See Peter Miller's "Recursive Make + Considered Harmful" at http://miller.emu.id.au/pmiller/books/rmch/ for + more information here. + + We now use the "quiet build" option to suppress distracting messages + about which commandlines are running. You can get them back with + "make V=1". + +4.4. Portability + + Libevent now uses large-file support internally on platforms where it + matters. You shouldn't need to set _LARGEFILE or OFFSET_BITS or + anything magic before including the Libevent headers, either, since + Libevent now sets the size of ev_off_t to the size of off_t that it + received at compile time, not to some (possibly different) size based + on current macro definitions when your program is building. + + We now also use the Autoconf AC_USE_SYSTEM_EXTENSIONS mechanism to + enable per-system macros needed to enable not-on-by-default features. + Unlike the rest of the autoconf macros, we output these to an + internal-use-only evconfig-private.h header, since their names need to + survive unmangled. This lets us build correctly on more platforms, + and avoid inconsistencies when some files define _GNU_SOURCE and + others don't. + + Libevent now tries to detect OpenSSL via pkg-config. + +4.5. Standards conformance + + Previous Libevent versions had no consistent convention for internal + vs external identifiers, and used identifiers starting with the "_" + character throughout the codebase. That's no good, since the C + standard says that identifiers beginning with _ are reserved. I'm not + aware of having any collisions with system identifiers, but it's best + to fix these things before they cause trouble. + + We now avoid all use of the _identifiers in the Libevent source code. + These changes were made *mainly* through the use of automated scripts, + so there shouldn't be any mistakes, but you never know. + + As an exception, the names _EVENT_LOG_DEBUG, _EVENT_LOG_MSG_, + _EVENT_LOG_WARN, and _EVENT_LOG_ERR are still exposed in event.h: they + are now deprecated, but to support older code, they will need to stay + around for a while. New code should use EVENT_LOG_DEBUG, + EVENT_LOG_MSG, EVENT_LOG_WARN, and EVENT_LOG_ERR instead. + +4.6. Event and callback refactoring + + As a simplification and optimization to Libevent's "deferred callback" + logic (introduced in 2.0 to avoid callback recursion), Libevent now + treats all of its deferrable callback types using the same logic it + uses for active events. Now deferred events no longer cause priority + inversion, no longer require special code to cancel them, and so on. + + Regular events and deferred callbacks now both descend from an + internal light-weight event_callback supertype, and both support + priorities and take part in the other anti-priority-inversion + mechanisms in Libevent. + + To avoid starvation from callback recursion (which was the reason we + introduced "deferred callbacks" in the first place) the implementation + now allows an event callback to be scheduled as "active later": + instead of running in the current iteration of the event loop, it runs + in the next one. + +5. Testing + + Libevent's test coverage level is more or less unchanged since before: + we still have over 80% line coverage in our tests on Linux, FreeBSD, NetBSD, + Windows, OSX. + There are some under-tested modules, though: we need to fix those. + + And now we have CI: + - https://travis-ci.org/libevent/libevent + - https://ci.appveyor.com/project/nmathewson/libevent + + And code coverage: + - https://coveralls.io/github/libevent/libevent + + Plus there is vagrant boxes if you what to test it on more OS'es then + travis-ci allows, and there is a wrapper (in python) that will parse logs and + provide report: + - https://github.com/libevent/libevent-extras/blob/master/tools/vagrant-tests.py + +6.
