98b7ca30	2024-11-02T21:39:57	http: allow passing in pre-existing connection bev (#1722) This patch adds functionality to pass a pre-existing connection as a bufferevent to `evhttp_connection_base_bufferevent_reuse_new`. When the bufferevent has an existing fd, the evcon starts in state `EVCON_IDLE` so that requests can be made immediately.

96c259f1	2024-06-26T12:10:00	tcpkeepalive: distinguish OS versions and use proper time units (#1669) DragonFly BSD changed the time unit for TCP keep-alive from milliseconds to seconds since v5.8 and Solaris 11.4 added `TCP_KEEPIDLE`, `TCP_KEEPINTVL`, and `TCP_KEEPCNT` with time units in second while Solaris <11.4 still use `TCP_KEEPALIVE_THRESHOLD` and `TCP_KEEPALIVE_ABORT_THRESHOLD` with time units in millisecond. Currently, we don't differentiate among DragonFly BSD versions but set the keepalive options with seconds, which will result in unexpected behaviors on DragonFlyBSD <5.8. This PR intends to fix the wrong usage of time units of TCP keepalive options on DragonFly BSD <5.8 and consolidate the logic of time units conversion for TCP keepalive across platforms. In addition, this PR introduces a new custom macro for determining Solaris 11.4. This macro is expected to help us implement some new features for `libuv` using some abilities that only exist on Solaris 11.4 and other mainstream platforms in the future, considering that Oracle developed and released Solaris 11.4 to replenish plenty of features on Solaris that have already been implemented on other UNIX-like OSs but missing from Solaris <11.4, also bring a good deal of new features. ### References - [Change tcp keepalive options from ms to seconds (DISRUPTIVE)](https://lists.dragonflybsd.org/pipermail/commits/2019-July/719125.html) - [DragonFly BSD 5.8 release notes](https://www.dragonflybsd.org/release58/) - [DragonFly TCP](https://man.dragonflybsd.org/?command=tcp&section=4) - [Solaris 11.3 TCP](https://docs.oracle.com/cd/E86824_01/html/E54777/tcp-7p.html) - [Solaris 11.4 TCP](https://docs.oracle.com/cd/E88353_01/html/E37851/tcp-4p.html) - [Solaris 11.4 release notes](https://docs.oracle.com/cd/E37838_01/html/E60973/) Signed-off-by: Andy Pan <i@andypan.me>

7658b788	2024-01-06T00:52:43	Implement full support of TCP Keep-Alives across most Unix-like OS's (#1532) Default settings of TCP keep-alive are not always feasible, take Linux for example, the duration a connection needs to be idle before sending out the first keep-alive probe is two hours, which makes detecting dead connections extremely deferred. Thus, enabling TCP keep-alive will be to little avail. This sets TCP_KEEPIDLE, TCP_KEEPINTVL, and TCP_KEEPCNT when enabling TCP keep-alive mechanism to make it practicable.
7f5b8f19	2023-11-18T15:55:14	Fix documentation inconsistency in evhttp callbacks This commit addresses a minor inconsistency identified in the documentation of multiple `evhttp` callback functions within the `event2/http.h` header file. It was observed that the word "additional" was presumably missing in the description of the `arg` parameter for several functions. This oversight led to an incorrect phrasing: "an context argument for the callback." The documentation for the following functions has been updated to rectify this issue: - `evhttp_set_gencb` - `evhttp_set_bevcb` - `evhttp_set_newreqcb` - `evhttp_set_errorcb` This commit solely improves the readability of the function descriptions without altering any functional aspects of the code.

But note, that this commit breaks the ABI compatibility, but it should be OK, since there was only alpha release with evws_send, and nobody should rely on this, and I hope nobody does (we decided to go this way to avoid supporting deprecated API).
57d9eec6	2023-07-10T10:40:49	Disable signalfd by default signalfd may behave differently to sigaction/signal, so to avoid breaking libevent users (like [1], [2]) disable it by default. [1]: https://github.com/tmux/tmux/pull/3621 [2]: https://github.com/tmux/tmux/pull/3626 Also signalfd is not that perfect: - you need to SIG_BLOCK the signal before - blocked signals are not reset on exec - blocked signals are allowed to coalesce - so in case of multiple signals sent you may get the signal only once (ok for most of the signals, but may be a problem for SIGCHLD, though you may call waitpid() in a loop or use pidfd) - and also one implementation problem - sigprocmask is unspecified in a multithreaded process Refs: - https://lwn.net/Articles/415684/ - https://ldpreload.com/blog/signalfd-is-useless Refs: https://github.com/libevent/libevent/issues/1460 Refs: #1342 (cc @dmantipov)

f9134df7	2023-02-04T15:00:48	Add LEV_OPT_BIND_IPV4_AND_IPV6 flag (#1400) Libevent introduced the LEV_OPT_BIND_IPV6ONLY to pass to evconnlistener_new_bind to make it automatically set the underlying socket as accepting ipv6 requests. This works fine on posix compliant platforms as by the standard every new AF_INET6 socket is created as both supporting ipv6 and ipv4 connections. But on windows the default is the opposite, with the flag IPV6_V6ONLY being always enabled by default. This makes creating a listener to supports both protocols a bit more tricky as winsock doesn't allow changing this flag after evconnlistener_new_bind does all the initial setup because as stated in the docs, you can't change it after the sonnect connected, so one would have to manually create the socket beforehand and set the flag and then call evconnlistener_new with the socket itself. It would be nice to have libevent keep a consistent behaviour across the platforms in this scenario, maybe or by making it always set IPV6_V6ONLY to false unless LEV_OPT_BIND_IPV6ONLY is passed, in which case it's set to true, or add another flag to forcefully set it to false and keep the system dependent behaviour as default. So this patch add new option for libevent listeners to bind to both - LEV_OPT_BIND_IPV4_AND_IPV6

e8313084	2022-09-12T22:16:56	Add minimal WebSocket server implementation for evhttp (#1322) This adds few functions to use evhttp-based webserver to handle incoming WebSockets connections. We've tried to use both libevent and libwebsockets in our application, but found that we need to have different ports at the same time to handle standard HTTP and WebSockets traffic. This change can help to stick only with libevent library. Implementation was inspired by modified Libevent source code in ipush project [1]. [1]: https://github.com/sqfasd/ipush/tree/master/deps/libevent-2.0.21-stable Also, WebSocket-based chat server was added as a sample.

I want libevent to support manual setting of MAX_PROBE_TIMEOUT and TIMEOUT_BACKOFF_FACTOR So move hardcoded MAX_PROBE_TIMEOUT and TIMEOUT_BACKOFF_FACTOR into struct, and allow changing them.

02905413	2016-02-09T18:01:00	Add callback support for error pages The existing error pages are very basic and don't allow for multi-lingual support or for conformity with other pages in a web site. The aim of the callback functionality is to allow custom error pages to be supported for calls to evhttp_send_error() by both calling applications and Libevent itself. A backward-incompatible change has been made to the title of error pages sent by evhttp_send_error(). The original version of the function used the reason argument as part of the title. That might have unforeseen side-effects if it contains HTML tags. Therefore the title has been changed to always use the standard status text. An example of the error callback can be found in this [version](https://github.com/libevent/libevent/files/123607/http-server.zip) of the 'http-server' sample. It will output error pages with very bright backgrounds, the error code using a very large font size and the reason. Closes: #323 (cherr-picked from PR)

8dcb94a4	2016-01-08T13:36:20	Added http method extending User can define his own response method by calling evhttp_set_ext_method_cmp() on the struct http, or evhttp_connection_set_ext_method_cmp() on the connection. We expose a new stucture `evhttp_ext_method` which is passed to the callback if it's set. So any field can be modified, with some exceptions (in evhttp_method_): If the cmp function is set, it has the ability to modify method, and flags. Other fields will be ignored. Flags returned are OR'd with the current flags. Based on changes to the #282 from: Mark Ellzey <socket@gmail.com>

5f87be42	2019-02-25T11:59:15	Define `_GNU_SOURCE` properly/consistently per autoconf Although `_GNU_SOURCE` can be defined as an arbitrary #define per the glibc docs [1], it's best to define it in a manner consistent with the way that autoconf defines it, i.e., `1`. While this shouldn't matter in most cases, it does when the headers from other projects follow the poorly defined GNU convention implemented by autoconf and are included after the libevent's util.h header. An example failure with clang, similar to the failure I encountered, is as follows: ``` $ printf "#define _GNU_SOURCE\n#define _GNU_SOURCE 1" \| clang -c -x c - <stdin>:2:9: warning: '_GNU_SOURCE' macro redefined [-Wmacro-redefined] ^ <stdin>:1:9: note: previous definition is here ^ 1 warning generated. ``` This happened when compiling python [2] with a stale homebrew util.h file from libevent (which admittedly would not happen in a correct libevent install, as the header should be installed under /usr/local/include/event2/util.h). However, if both headers had been combined (which is more likely), it would have failed as shown above. Removing the ad hoc definition unbreaks compiling python's pyconfig.h.in header when included after util.h from libevent. 1. http://www.gnu.org/software/libc/manual/html_node/Feature-Test-Macros.html 2. https://github.com/python/cpython/blob/master/configure.ac#L126 Closes: #773 (cherry-picked) Signed-off-by: Enji Cooper <yaneurabeya@gmail.com>

tcpkeepalive: distinguish OS versions and use proper time units (#1669) DragonFly BSD changed the time unit for TCP keep-alive from milliseconds to seconds since v5.8 and Solaris 11.4 added `TCP_KEEPIDLE`, `TCP_KEEPINTVL`, and `TCP_KEEPCNT` with time units in second while Solaris <11.4 still use `TCP_KEEPALIVE_THRESHOLD` and `TCP_KEEPALIVE_ABORT_THRESHOLD` with time units in millisecond. Currently, we don't differentiate among DragonFly BSD versions but set the keepalive options with seconds, which will result in unexpected behaviors on DragonFlyBSD <5.8. This PR intends to fix the wrong usage of time units of TCP keepalive options on DragonFly BSD <5.8 and consolidate the logic of time units conversion for TCP keepalive across platforms. In addition, this PR introduces a new custom macro for determining Solaris 11.4. This macro is expected to help us implement some new features for `libuv` using some abilities that only exist on Solaris 11.4 and other mainstream platforms in the future, considering that Oracle developed and released Solaris 11.4 to replenish plenty of features on Solaris that have already been implemented on other UNIX-like OSs but missing from Solaris <11.4, also bring a good deal of new features. ### References - [Change tcp keepalive options from ms to seconds (DISRUPTIVE)](https://lists.dragonflybsd.org/pipermail/commits/2019-July/719125.html) - [DragonFly BSD 5.8 release notes](https://www.dragonflybsd.org/release58/) - [DragonFly TCP](https://man.dragonflybsd.org/?command=tcp&section=4) - [Solaris 11.3 TCP](https://docs.oracle.com/cd/E86824_01/html/E54777/tcp-7p.html) - [Solaris 11.4 TCP](https://docs.oracle.com/cd/E88353_01/html/E37851/tcp-4p.html) - [Solaris 11.4 release notes](https://docs.oracle.com/cd/E37838_01/html/E60973/) Signed-off-by: Andy Pan <i@andypan.me>

Implement full support of TCP Keep-Alives across most Unix-like OS's (#1532) Default settings of TCP keep-alive are not always feasible, take Linux for example, the duration a connection needs to be idle before sending out the first keep-alive probe is two hours, which makes detecting dead connections extremely deferred. Thus, enabling TCP keep-alive will be to little avail. This sets TCP_KEEPIDLE, TCP_KEEPINTVL, and TCP_KEEPCNT when enabling TCP keep-alive mechanism to make it practicable.

Fix documentation inconsistency in evhttp callbacks This commit addresses a minor inconsistency identified in the documentation of multiple `evhttp` callback functions within the `event2/http.h` header file. It was observed that the word "additional" was presumably missing in the description of the `arg` parameter for several functions. This oversight led to an incorrect phrasing: "an context argument for the callback." The documentation for the following functions has been updated to rectify this issue: - `evhttp_set_gencb` - `evhttp_set_bevcb` - `evhttp_set_newreqcb` - `evhttp_set_errorcb` This commit solely improves the readability of the function descriptions without altering any functional aspects of the code.

Disable signalfd by default signalfd may behave differently to sigaction/signal, so to avoid breaking libevent users (like [1], [2]) disable it by default. [1]: https://github.com/tmux/tmux/pull/3621 [2]: https://github.com/tmux/tmux/pull/3626 Also signalfd is not that perfect: - you need to SIG_BLOCK the signal before - blocked signals are not reset on exec - blocked signals are allowed to coalesce - so in case of multiple signals sent you may get the signal only once (ok for most of the signals, but may be a problem for SIGCHLD, though you may call waitpid() in a loop or use pidfd) - and also one implementation problem - sigprocmask is unspecified in a multithreaded process Refs: - https://lwn.net/Articles/415684/ - https://ldpreload.com/blog/signalfd-is-useless Refs: https://github.com/libevent/libevent/issues/1460 Refs: #1342 (cc @dmantipov)

Add LEV_OPT_BIND_IPV4_AND_IPV6 flag (#1400) Libevent introduced the LEV_OPT_BIND_IPV6ONLY to pass to evconnlistener_new_bind to make it automatically set the underlying socket as accepting ipv6 requests. This works fine on posix compliant platforms as by the standard every new AF_INET6 socket is created as both supporting ipv6 and ipv4 connections. But on windows the default is the opposite, with the flag IPV6_V6ONLY being always enabled by default. This makes creating a listener to supports both protocols a bit more tricky as winsock doesn't allow changing this flag after evconnlistener_new_bind does all the initial setup because as stated in the docs, you can't change it after the sonnect connected, so one would have to manually create the socket beforehand and set the flag and then call evconnlistener_new with the socket itself. It would be nice to have libevent keep a consistent behaviour across the platforms in this scenario, maybe or by making it always set IPV6_V6ONLY to false unless LEV_OPT_BIND_IPV6ONLY is passed, in which case it's set to true, or add another flag to forcefully set it to false and keep the system dependent behaviour as default. So this patch add new option for libevent listeners to bind to both - LEV_OPT_BIND_IPV4_AND_IPV6

We've tried to use both libevent and libwebsockets in our application, but found that we need to have different ports at the same time to handle standard HTTP and WebSockets traffic. This change can help to stick only with libevent library. Implementation was inspired by modified Libevent source code in ipush project [1]. [1]: https://github.com/sqfasd/ipush/tree/master/deps/libevent-2.0.21-stable Also, WebSocket-based chat server was added as a sample.

build: remove splice implementation fragments Looks like a `splice` implementation was planned, but has clearly never eventuated (the TODO comment is from ~12 years ago, in 8b5bd77415fb6634fadf08357676926fecf5f032). For now, it's probably better to remove the unused code/correct the docs.

evdns: add max-probe-timeout/probe-backoff-factor settings I recently found that when the network status changed when calling bufferevent_socket_connect_hostname (e.g. switching between several WIFIs), all DNS servers would fail, and the timeout of probe would be very long if there were many DNS requests. I want libevent to support manual setting of MAX_PROBE_TIMEOUT and TIMEOUT_BACKOFF_FACTOR So move hardcoded MAX_PROBE_TIMEOUT and TIMEOUT_BACKOFF_FACTOR into struct, and allow changing them.

http: eliminate redundant bev fd manipulating and caching [WIP] At the very beginning we reset the bufferevent fd (if bev has it), which is not a good idea, since if user passes bufferevent with existing fd he has some intention. So we need to: - use BEV_OPT_CLOSE_ON_FREE for default bufferevent_socket_new() (to avoid manual shutdown/closee) - drop getsockopt(SOL_SOCKET, SO_ERROR), since bufferevent already has evutil_socket_finished_connecting_() - drop supperior bufferevent_setfd(bev, -1) in evhttp_connection_connect_() Closes: #795 Refs: #875

This can be used to prevent servers from running out of file descriptors. This is better than request limiting because clients may make more than one request over a single connection. Blocking a request does not necessarily close the connection and free up a socket." * http-max_connections-pr-592: test: cover evhttp max connections Added evhttp max simultaneous connection limiting

Add callback support for error pages The existing error pages are very basic and don't allow for multi-lingual support or for conformity with other pages in a web site. The aim of the callback functionality is to allow custom error pages to be supported for calls to evhttp_send_error() by both calling applications and Libevent itself. A backward-incompatible change has been made to the title of error pages sent by evhttp_send_error(). The original version of the function used the reason argument as part of the title. That might have unforeseen side-effects if it contains HTML tags. Therefore the title has been changed to always use the standard status text. An example of the error callback can be found in this [version](https://github.com/libevent/libevent/files/123607/http-server.zip) of the 'http-server' sample. It will output error pages with very bright backgrounds, the error code using a very large font size and the reason. Closes: #323 (cherr-picked from PR)

Adding `@brief` command can fix it. - The parameters in the function declaration are different from the parameters following the `@param` command.We should change them to the same. - Documentation of `watch.h` is not generated since `watch.h` has not been added to the Doxyfile `INPUT` tag. - Add link to the watch.h in event.h

Added http method extending User can define his own response method by calling evhttp_set_ext_method_cmp() on the struct http, or evhttp_connection_set_ext_method_cmp() on the connection. We expose a new stucture `evhttp_ext_method` which is passed to the callback if it's set. So any field can be modified, with some exceptions (in evhttp_method_): If the cmp function is set, it has the ability to modify method, and flags. Other fields will be ignored. Flags returned are OR'd with the current flags. Based on changes to the #282 from: Mark Ellzey <socket@gmail.com>

Maximum evbuffer read configuration Before this patch evbuffer always reads 4K at a time, while this is fine most of time you can find an example when this will decrease throughput. So add an API to change default limit: - evbuffer_set_max_read() - evbuffer_get_max_read() And a notice that most of time default is sane.

Define `_GNU_SOURCE` properly/consistently per autoconf Although `_GNU_SOURCE` can be defined as an arbitrary #define per the glibc docs [1], it's best to define it in a manner consistent with the way that autoconf defines it, i.e., `1`. While this shouldn't matter in most cases, it does when the headers from other projects follow the poorly defined GNU convention implemented by autoconf and are included after the libevent's util.h header. An example failure with clang, similar to the failure I encountered, is as follows: ``` $ printf "#define _GNU_SOURCE\n#define _GNU_SOURCE 1" | clang -c -x c - <stdin>:2:9: warning: '_GNU_SOURCE' macro redefined [-Wmacro-redefined] ^ <stdin>:1:9: note: previous definition is here ^ 1 warning generated. ``` This happened when compiling python [2] with a stale homebrew util.h file from libevent (which admittedly would not happen in a correct libevent install, as the header should be installed under /usr/local/include/event2/util.h). However, if both headers had been combined (which is more likely), it would have failed as shown above. Removing the ad hoc definition unbreaks compiling python's pyconfig.h.in header when included after util.h from libevent. 1. http://www.gnu.org/software/libc/manual/html_node/Feature-Test-Macros.html 2. https://github.com/python/cpython/blob/master/configure.ac#L126 Closes: #773 (cherry-picked) Signed-off-by: Enji Cooper <yaneurabeya@gmail.com>
