1991, 1999 Free Software Foundation, Inc. -51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA -Everyone is permitted to copy and distribute verbatim copies -of this license document, but changing it is not allowed. - -[This is the first released version of the Lesser GPL. It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] -Preamble - -The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. - -This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. - -When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. - -To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. - -For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. - -We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. - -To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. - -Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. - -Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. - -When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. - -We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. - -For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. - -In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. - -Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. - -The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. - -TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - -0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". - -A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. - -The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) - -"Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. - -Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. - -1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. - -You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. - -2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: - -a) The modified work must itself be a software library. -b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. -c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. -d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. -(For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. - -3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. - -Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. - -This option is useful when you wish to copy part of the code of the Library into a program that is not a library. - -4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. - -If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. - -5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. - -However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. - -When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. - -If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) - -Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. - -6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. - -You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: - -a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) -b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. -c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. -d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. -e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. -For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. - -It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. - -7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: - -a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. -b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. -8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. - -9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. - -10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. - -11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. - -This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. - -12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. - -13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. - -14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. - -NO WARRANTY - -15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - -16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. - -END OF TERMS AND CONDITIONS - -How to Apply These Terms to Your New Libraries - -If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). - -To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. - -one line to give the library's name and an idea of what it does. -Copyright (C) year name of author - -This library is free software; you can redistribute it and/or -modify it under the terms of the GNU Lesser General Public -License as published by the Free Software Foundation; either -version 2.1 of the License, or (at your option) any later version. - -This library is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU -Lesser General Public License for more details. - -You should have received a copy of the GNU Lesser General Public -License along with this library; if not, write to the Free Software -Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA -Also add information on how to contact you by electronic and paper mail. - -You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

If nothing was -# specified when calling configure, it searches first in /usr/local and -# then in /usr, /opt/local and /sw. If the --with-zlib=DIR is specified, -# it will try to find it in DIR/include/zlib.h and DIR/lib/libz.a. If -# --without-zlib is specified, the library is not searched at all. -# -# If either the header file (zlib.h) or the library (libz) is not found, -# shell commands 'action-if-not-found' is run. If 'action-if-not-found' is -# not specified, the configuration exits on error, asking for a valid zlib -# installation directory or --without-zlib. -# -# If both header file and library are found, shell commands -# 'action-if-found' is run. If 'action-if-found' is not specified, the -# default action appends '-I${ZLIB_HOME}/include' to CPFLAGS, appends -# '-L$ZLIB_HOME}/lib' to LDFLAGS, prepends '-lz' to LIBS, and calls -# AC_DEFINE(HAVE_LIBZ). You should use autoheader to include a definition -# for this symbol in a config.h file.

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 Removed obsoleted recalc code - 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 fix a bug with event_rpcgen for integers - o move EV_PERSIST handling out of the event backends - o support for 32-bit tag numbers in rpc structures; this is wire compatible, but changes the API slightly. - o prefix {encode,decode}_tag functions with evtag to avoid collisions - o Correctly handle DNS replies with no answers set (Fixes bug 1846282) - 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 When building with GCC, use the "format" attribute to verify type correctness of calls to printf-like functions. - o removed linger from http server socket; reported by Ilya Martynov - 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 would 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/libs/tgl/libevent/ChangeLog-2.0 b/libs/tgl/libevent/ChangeLog-2.0 deleted file mode 100644 index a925d33b18..0000000000 --- a/libs/tgl/libevent/ChangeLog-2.0 +++ /dev/null @@ -1,1280 +0,0 @@ -Changes in version 2.0.21-stable (18 Nov 2012) -BUGFIXES: - o ssl: Don't discard SSL read event when timeout and read come close together (576b29f) - o ssl: Stop looping in "consider_reading" if reading is suspended.

(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. - diff --git a/libs/tgl/libevent/Doxyfile b/libs/tgl/libevent/Doxyfile deleted file mode 100644 index d9d6603459..0000000000 --- a/libs/tgl/libevent/Doxyfile +++ /dev/null @@ -1,257 +0,0 @@ -# Doxyfile 1.5.1 - -# This file describes the settings to be used by the documentation system -# doxygen (www.doxygen.org) for a project -# -# All text after a hash (#) is considered a comment and will be ignored -# The format is: -# TAG = value [value, ...] -# For lists items can also be appended using: -# TAG += value [value, ...] -# Values that contain spaces should be placed between quotes (" ") - -#--------------------------------------------------------------------------- -# Project related configuration options -#--------------------------------------------------------------------------- - -# The PROJECT_NAME tag is a single word (or a sequence of words surrounded -# by quotes) that should identify the project. - -PROJECT_NAME = libevent - -# Place all output under 'doxygen/' - -OUTPUT_DIRECTORY = doxygen/ - -# If the JAVADOC_AUTOBRIEF tag is set to YES then Doxygen -# will interpret the first line (until the first dot) of a JavaDoc-style -# comment as the brief description.

Before you use this library you should see if libc -can do the job for you with the modern async call getaddrinfo_a -(see http://www.imperialviolet.org/page25.html#e498). Otherwise, -please continue. -.Pp -This code is based on libevent and you must call event_init before -any of the APIs in this file. You must also seed the OpenSSL random -source if you are using OpenSSL for ids (see below). -.Pp -This library is designed to be included and shipped with your source -code. You statically link with it. You should also test for the -existence of strtok_r and define HAVE_STRTOK_R if you have it. -.Pp -The DNS protocol requires a good source of id numbers and these -numbers should be unpredictable for spoofing reasons. There are -three methods for generating them here and you must define exactly -one of them. In increasing order of preference: -.Pp -.Bl -tag -width "DNS_USE_GETTIMEOFDAY_FOR_ID" -compact -offset indent -.It DNS_USE_GETTIMEOFDAY_FOR_ID -Using the bottom 16 bits of the usec result from gettimeofday. This -is a pretty poor solution but should work anywhere. -.It DNS_USE_CPU_CLOCK_FOR_ID -Using the bottom 16 bits of the nsec result from the CPU's time -counter. This is better, but may not work everywhere. Requires -POSIX realtime support and you'll need to link against -lrt on -glibc systems at least. -.It DNS_USE_OPENSSL_FOR_ID -Uses the OpenSSL RAND_bytes call to generate the data. You must -have seeded the pool before making any calls to this library. -.El -.Pp -The library keeps track of the state of nameservers and will avoid -them when they go down. Otherwise it will round robin between them. -.Pp -Quick start guide: - #include "evdns.h" - void callback(int result, char type, int count, int ttl, - void *addresses, void *arg); - evdns_resolv_conf_parse(DNS_OPTIONS_ALL, "/etc/resolv.conf"); - evdns_resolve("www.hostname.com", 0, callback, NULL); -.Pp -When the lookup is complete the callback function is called. The -first argument will be one of the DNS_ERR_* defines in evdns.h. -Hopefully it will be DNS_ERR_NONE, in which case type will be -DNS_IPv4_A, count will be the number of IP addresses, ttl is the time -which the data can be cached for (in seconds), addresses will point -to an array of uint32_t's and arg will be whatever you passed to -evdns_resolve. -.Pp -Searching: -.Pp -In order for this library to be a good replacement for glibc's resolver it -supports searching. This involves setting a list of default domains, in -which names will be queried for. The number of dots in the query name -determines the order in which this list is used. -.Pp -Searching appears to be a single lookup from the point of view of the API, -although many DNS queries may be generated from a single call to -evdns_resolve. Searching can also drastically slow down the resolution -of names. -.Pp -To disable searching: -.Bl -enum -compact -offset indent -.It -Never set it up. If you never call -.Fn evdns_resolv_conf_parse, -.Fn evdns_init, -or -.Fn evdns_search_add -then no searching will occur. -.It -If you do call -.Fn evdns_resolv_conf_parse -then don't pass -.Va DNS_OPTION_SEARCH -(or -.Va DNS_OPTIONS_ALL, -which implies it). -.It -When calling -.Fn evdns_resolve, -pass the -.Va DNS_QUERY_NO_SEARCH -flag. -.El -.Pp -The order of searches depends on the number of dots in the name. If the -number is greater than the ndots setting then the names is first tried -globally. Otherwise each search domain is appended in turn. -.Pp -The ndots setting can either be set from a resolv.conf, or by calling -evdns_search_ndots_set. -.Pp -For example, with ndots set to 1 (the default) and a search domain list of -["myhome.net"]: - Query: www - Order: www.myhome.net, www. -.Pp - Query: www.abc - Order: www.abc., www.abc.myhome.net -.Pp -.Sh API reference -.Pp -.Bl -tag -width 0123456 -.It Ft int Fn evdns_init -Initializes support for non-blocking name resolution by calling -.Fn evdns_resolv_conf_parse -on UNIX and -.Fn evdns_config_windows_nameservers -on Windows. -.It Ft int Fn evdns_nameserver_add "unsigned long int address" -Add a nameserver. The address should be an IP address in -network byte order. The type of address is chosen so that -it matches in_addr.s_addr. -Returns non-zero on error. -.It Ft int Fn evdns_nameserver_ip_add "const char *ip_as_string" -This wraps the above function by parsing a string as an IP -address and adds it as a nameserver. -Returns non-zero on error -.It Ft int Fn evdns_resolve "const char *name" "int flags" "evdns_callback_type callback" "void *ptr" -Resolve a name. The name parameter should be a DNS name. -The flags parameter should be 0, or DNS_QUERY_NO_SEARCH -which disables searching for this query. (see defn of -searching above). -.Pp -The callback argument is a function which is called when -this query completes and ptr is an argument which is passed -to that callback function. -.Pp -Returns non-zero on error -.It Ft void Fn evdns_search_clear -Clears the list of search domains -.It Ft void Fn evdns_search_add "const char *domain" -Add a domain to the list of search domains -.It Ft void Fn evdns_search_ndots_set "int ndots" -Set the number of dots which, when found in a name, causes -the first query to be without any search domain. -.It Ft int Fn evdns_count_nameservers "void" -Return the number of configured nameservers (not necessarily the -number of running nameservers). This is useful for double-checking -whether our calls to the various nameserver configuration functions -have been successful. -.It Ft int Fn evdns_clear_nameservers_and_suspend "void" -Remove all currently configured nameservers, and suspend all pending -resolves. Resolves will not necessarily be re-attempted until -evdns_resume() is called. -.It Ft int Fn evdns_resume "void" -Re-attempt resolves left in limbo after an earlier call to -evdns_clear_nameservers_and_suspend(). -.It Ft int Fn evdns_config_windows_nameservers "void" -Attempt to configure a set of nameservers based on platform settings on -a win32 host. Preferentially tries to use GetNetworkParams; if that fails, -looks in the registry. Returns 0 on success, nonzero on failure. -.It Ft int Fn evdns_resolv_conf_parse "int flags" "const char *filename" -Parse a resolv.conf like file from the given filename. -.Pp -See the man page for resolv.conf for the format of this file. -The flags argument determines what information is parsed from -this file: -.Bl -tag -width "DNS_OPTION_NAMESERVERS" -offset indent -compact -nested -.It DNS_OPTION_SEARCH -domain, search and ndots options -.It DNS_OPTION_NAMESERVERS -nameserver lines -.It DNS_OPTION_MISC -timeout and attempts options -.It DNS_OPTIONS_ALL -all of the above -.El -.Pp -The following directives are not parsed from the file: - sortlist, rotate, no-check-names, inet6, debug -.Pp -Returns non-zero on error: -.Bl -tag -width "0" -offset indent -compact -nested -.It 0 -no errors -.It 1 -failed to open file -.It 2 -failed to stat file -.It 3 -file too large -.It 4 -out of memory -.It 5 -short read from file -.El -.El -.Sh Internals: -Requests are kept in two queues. The first is the inflight queue. In -this queue requests have an allocated transaction id and nameserver. -They will soon be transmitted if they haven't already been. -.Pp -The second is the waiting queue. The size of the inflight ring is -limited and all other requests wait in waiting queue for space. This -bounds the number of concurrent requests so that we don't flood the -nameserver. Several algorithms require a full walk of the inflight -queue and so bounding its size keeps thing going nicely under huge -(many thousands of requests) loads. -.Pp -If a nameserver loses too many requests it is considered down and we -try not to use it. After a while we send a probe to that nameserver -(a lookup for google.com) and, if it replies, we consider it working -again. If the nameserver fails a probe we wait longer to try again -with the next probe. -.Sh SEE ALSO -.Xr event 3 , -.Xr gethostbyname 3 , -.Xr resolv.conf 5 -.Sh HISTORY -The -.Nm evdns -API was developed by Adam Langley on top of the -.Nm libevent -API. -The code was integrate into -.Nm Tor -by Nick Mathewson and finally put into -.Nm libevent -itself by Niels Provos. -.Sh AUTHORS -The -.Nm evdns -API and code was written by Adam Langley with significant -contributions by Nick Mathewson. -.Sh BUGS -This documentation is neither complete nor authoritative. -If you are in doubt about the usage of this API then -check the source code to find out how it works, write -up the missing piece of documentation and send it to -me for inclusion in this man page. diff --git a/libs/tgl/libevent/evdns.c b/libs/tgl/libevent/evdns.c deleted file mode 100644 index c4112330a9..0000000000 --- a/libs/tgl/libevent/evdns.c +++ /dev/null @@ -1,4761 +0,0 @@ -/* Copyright 2006-2007 Niels Provos - * Copyright 2007-2012 Nick Mathewson and Niels Provos - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * 1.

event -API provides a mechanism to execute a function when a specific event -on a file descriptor occurs or after a given time has passed. -.Pp -The -.Nm event -API needs to be initialized with -.Fn event_init -before it can be used. -.Pp -In order to process events, an application needs to call -.Fn event_dispatch . -This function only returns on error, and should replace the event core -of the application program. -.Pp -The function -.Fn event_set -prepares the event structure -.Fa ev -to be used in future calls to -.Fn event_add -and -.Fn event_del . -The event will be prepared to call the function specified by the -.Fa fn -argument with an -.Fa int -argument indicating the file descriptor, a -.Fa short -argument indicating the type of event, and a -.Fa void * -argument given in the -.Fa arg -argument. -The -.Fa fd -indicates the file descriptor that should be monitored for events. -The events can be either -.Va EV_READ , -.Va EV_WRITE , -or both, -indicating that an application can read or write from the file descriptor -respectively without blocking. -.Pp -The function -.Fa fn -will be called with the file descriptor that triggered the event and -the type of event which will be either -.Va EV_TIMEOUT , -.Va EV_SIGNAL , -.Va EV_READ , -or -.Va EV_WRITE . -Additionally, an event which has registered interest in more than one of the -preceeding events, via bitwise-OR to -.Fn event_set , -can provide its callback function with a bitwise-OR of more than one triggered -event. -The additional flag -.Va EV_PERSIST -makes an -.Fn event_add -persistent until -.Fn event_del -has been called. -.Pp -Once initialized, the -.Fa ev -structure can be used repeatedly with -.Fn event_add -and -.Fn event_del -and does not need to be reinitialized unless the function called and/or -the argument to it are to be changed. -However, when an -.Fa ev -structure has been added to libevent using -.Fn event_add -the structure must persist until the event occurs (assuming -.Fa EV_PERSIST -is not set) or is removed -using -.Fn event_del . -You may not reuse the same -.Fa ev -structure for multiple monitored descriptors; each descriptor -needs its own -.Fa ev . -.Pp -The function -.Fn event_add -schedules the execution of the -.Fa ev -event when the event specified in -.Fn event_set -occurs or in at least the time specified in the -.Fa tv . -If -.Fa tv -is -.Dv NULL , -no timeout occurs and the function will only be called -if a matching event occurs on the file descriptor. -The event in the -.Fa ev -argument must be already initialized by -.Fn event_set -and may not be used in calls to -.Fn event_set -until it has timed out or been removed with -.Fn event_del . -If the event in the -.Fa ev -argument already has a scheduled timeout, the old timeout will be -replaced by the new one. -.Pp -The function -.Fn event_del -will cancel the event in the argument -.Fa ev . -If the event has already executed or has never been added -the call will have no effect. -.Pp -The functions -.Fn evtimer_set , -.Fn evtimer_add , -.Fn evtimer_del , -.Fn evtimer_initialized , -and -.Fn evtimer_pending -are abbreviations for common situations where only a timeout is required. -The file descriptor passed will be \-1, and the event type will be -.Va EV_TIMEOUT . -.Pp -The functions -.Fn signal_set , -.Fn signal_add , -.Fn signal_del , -.Fn signal_initialized , -and -.Fn signal_pending -are abbreviations. -The event type will be a persistent -.Va EV_SIGNAL . -That means -.Fn signal_set -adds -.Va EV_PERSIST . -.Pp -In order to avoid races in signal handlers, the -.Nm event -API provides two variables: -.Va event_sigcb -and -.Va event_gotsig . -A signal handler -sets -.Va event_gotsig -to indicate that a signal has been received. -The application sets -.Va event_sigcb -to a callback function. -After the signal handler sets -.Va event_gotsig , -.Nm event_dispatch -will execute the callback function to process received signals. -The callback returns 1 when no events are registered any more. -It can return \-1 to indicate an error to the -.Nm event -library, causing -.Fn event_dispatch -to terminate with -.Va errno -set to -.Er EINTR . -.Pp -The function -.Fn event_once -is similar to -.Fn event_set . -However, it schedules a callback to be called exactly once and does not -require the caller to prepare an -.Fa event -structure. -This function supports -.Fa EV_TIMEOUT , -.Fa EV_READ , -and -.Fa EV_WRITE . -.Pp -The -.Fn event_pending -function can be used to check if the event specified by -.Fa event -is pending to run. -If -.Va EV_TIMEOUT -was specified and -.Fa tv -is not -.Dv NULL , -the expiration time of the event will be returned in -.Fa tv . -.Pp -The -.Fn event_initialized -macro can be used to check if an event has been initialized. -.Pp -The -.Nm event_loop -function provides an interface for single pass execution of pending -events. -The flags -.Va EVLOOP_ONCE -and -.Va EVLOOP_NONBLOCK -are recognized. -The -.Nm event_loopexit -function exits from the event loop. The next -.Fn event_loop -iteration after the -given timer expires will complete normally (handling all queued events) then -exit without blocking for events again. Subsequent invocations of -.Fn event_loop -will proceed normally. -The -.Nm event_loopbreak -function exits from the event loop immediately. -.Fn event_loop -will abort after the next event is completed; -.Fn event_loopbreak -is typically invoked from this event's callback. This behavior is analogous -to the "break;" statement. Subsequent invocations of -.Fn event_loop -will proceed normally. -.Pp -It is the responsibility of the caller to provide these functions with -pre-allocated event structures. -.Pp -.Sh EVENT PRIORITIES -By default -.Nm libevent -schedules all active events with the same priority. -However, sometimes it is desirable to process some events with a higher -priority than others. -For that reason, -.Nm libevent -supports strict priority queues. -Active events with a lower priority are always processed before events -with a higher priority. -.Pp -The number of different priorities can be set initially with the -.Fn event_priority_init -function. -This function should be called before the first call to -.Fn event_dispatch . -The -.Fn event_priority_set -function can be used to assign a priority to an event. -By default, -.Nm libevent -assigns the middle priority to all events unless their priority -is explicitly set. -.Sh THREAD SAFE EVENTS -.Nm Libevent -has experimental support for thread-safe events. -When initializing the library via -.Fn event_init , -an event base is returned. -This event base can be used in conjunction with calls to -.Fn event_base_set , -.Fn event_base_dispatch , -.Fn event_base_loop , -.Fn event_base_loopexit , -.Fn bufferevent_base_set -and -.Fn event_base_free . -.Fn event_base_set -should be called after preparing an event with -.Fn event_set , -as -.Fn event_set -assigns the provided event to the most recently created event base. -.Fn bufferevent_base_set -should be called after preparing a bufferevent with -.Fn bufferevent_new . -.Fn event_base_free -should be used to free memory associated with the event base -when it is no longer needed. -.Sh BUFFERED EVENTS -.Nm libevent -provides an abstraction on top of the regular event callbacks. -This abstraction is called a -.Va "buffered event" . -A buffered event provides input and output buffers that get filled -and drained automatically. -The user of a buffered event no longer deals directly with the IO, -but instead is reading from input and writing to output buffers. -.Pp -A new bufferevent is created by -.Fn bufferevent_new . -The parameter -.Fa fd -specifies the file descriptor from which data is read and written to. -This file descriptor is not allowed to be a -.Xr pipe 2 . -The next three parameters are callbacks. -The read and write callback have the following form: -.Ft void -.Fn "(*cb)" "struct bufferevent *bufev" "void *arg" . -The error callback has the following form: -.Ft void -.Fn "(*cb)" "struct bufferevent *bufev" "short what" "void *arg" . -The argument is specified by the fourth parameter -.Fa "cbarg" . -A -.Fa bufferevent struct -pointer is returned on success, NULL on error. -Both the read and the write callback may be NULL. -The error callback has to be always provided. -.Pp -Once initialized, the bufferevent structure can be used repeatedly with -bufferevent_enable() and bufferevent_disable(). -The flags parameter can be a combination of -.Va EV_READ -and -.Va EV_WRITE . -When read enabled the bufferevent will try to read from the file -descriptor and call the read callback. -The write callback is executed -whenever the output buffer is drained below the write low watermark, -which is -.Va 0 -by default. -.Pp -The -.Fn bufferevent_write -function can be used to write data to the file descriptor. -The data is appended to the output buffer and written to the descriptor -automatically as it becomes available for writing. -.Fn bufferevent_write -returns 0 on success or \-1 on failure. -The -.Fn bufferevent_read -function is used to read data from the input buffer, -returning the amount of data read. -.Pp -If multiple bases are in use, bufferevent_base_set() must be called before -enabling the bufferevent for the first time. -.Sh NON-BLOCKING HTTP SUPPORT -.Nm libevent -provides a very thin HTTP layer that can be used both to host an HTTP -server and also to make HTTP requests. -An HTTP server can be created by calling -.Fn evhttp_new . -It can be bound to any port and address with the -.Fn evhttp_bind_socket -function. -When the HTTP server is no longer used, it can be freed via -.Fn evhttp_free . -.Pp -To be notified of HTTP requests, a user needs to register callbacks with the -HTTP server. -This can be done by calling -.Fn evhttp_set_cb . -The second argument is the URI for which a callback is being registered. -The corresponding callback will receive an -.Va struct evhttp_request -object that contains all information about the request. -.Pp -This section does not document all the possible function calls; please -check -.Va event.h -for the public interfaces. -.Sh ADDITIONAL NOTES -It is possible to disable support for -.Va epoll , kqueue , devpoll , poll -or -.Va select -by setting the environment variable -.Va EVENT_NOEPOLL , EVENT_NOKQUEUE , EVENT_NODEVPOLL , EVENT_NOPOLL -or -.Va EVENT_NOSELECT , -respectively. -By setting the environment variable -.Va EVENT_SHOW_METHOD , -.Nm libevent -displays the kernel notification method that it uses. -.Sh RETURN VALUES -Upon successful completion -.Fn event_add -and -.Fn event_del -return 0. -Otherwise, \-1 is returned and the global variable errno is -set to indicate the error. -.Sh SEE ALSO -.Xr kqueue 2 , -.Xr poll 2 , -.Xr select 2 , -.Xr evdns 3 , -.Xr timeout 9 -.Sh HISTORY -The -.Nm event -API manpage is based on the -.Xr timeout 9 -manpage by Artur Grabowski. -The port of -.Nm libevent -to Windows is due to Michael A. Davis. -Support for real-time signals is due to Taral. -.Sh AUTHORS -The -.Nm event -library was written by Niels Provos. -.Sh BUGS -This documentation is neither complete nor authoritative. -If you are in doubt about the usage of this API then -check the source code to find out how it works, write -up the missing piece of documentation and send it to -me for inclusion in this man page. diff --git a/libs/tgl/libevent/event.c b/libs/tgl/libevent/event.c deleted file mode 100644 index 503003e249..0000000000 --- a/libs/tgl/libevent/event.c +++ /dev/null @@ -1,3940 +0,0 @@ -/* - * Copyright (c) 2000-2007 Niels Provos - * Copyright (c) 2007-2012 Niels Provos and Nick Mathewson - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * 1.

-
Socket-based bufferevents
-
A bufferevent that reads and writes data onto a network - socket. Created with bufferevent_socket_new().
- -
Paired bufferevents
-
A pair of bufferevents that send and receive data to one - another without touching the network. Created with - bufferevent_pair_new().
- -
Filtering bufferevents
-
A bufferevent that transforms data, and sends or receives it - over another underlying bufferevent. Created with - bufferevent_filter_new().
- -
SSL-backed bufferevents
-
A bufferevent that uses the openssl library to send and - receive data over an encrypted connection. Created with - bufferevent_openssl_socket_new() or - bufferevent_openssl_filter_new().

Before you use this library you should see if libc - * can do the job for you with the modern async call getaddrinfo_a - * (see http://www.imperialviolet.org/page25.html#e498). Otherwise, - * please continue. - * - * The library keeps track of the state of nameservers and will avoid - * them when they go down. Otherwise it will round robin between them. - * - * Quick start guide: - * #include "evdns.h" - * void callback(int result, char type, int count, int ttl, - * void *addresses, void *arg); - * evdns_resolv_conf_parse(DNS_OPTIONS_ALL, "/etc/resolv.conf"); - * evdns_resolve("www.hostname.com", 0, callback, NULL); - * - * When the lookup is complete the callback function is called. The - * first argument will be one of the DNS_ERR_* defines in evdns.h. - * Hopefully it will be DNS_ERR_NONE, in which case type will be - * DNS_IPv4_A, count will be the number of IP addresses, ttl is the time - * which the data can be cached for (in seconds), addresses will point - * to an array of uint32_t's and arg will be whatever you passed to - * evdns_resolve. - * - * Searching: - * - * In order for this library to be a good replacement for glibc's resolver it - * supports searching. This involves setting a list of default domains, in - * which names will be queried for. The number of dots in the query name - * determines the order in which this list is used. - * - * Searching appears to be a single lookup from the point of view of the API, - * although many DNS queries may be generated from a single call to - * evdns_resolve. Searching can also drastically slow down the resolution - * of names. - * - * To disable searching: - * 1. Never set it up. If you never call evdns_resolv_conf_parse or - * evdns_search_add then no searching will occur. - * - * 2. If you do call evdns_resolv_conf_parse then don't pass - * DNS_OPTION_SEARCH (or DNS_OPTIONS_ALL, which implies it). - * - * 3. When calling evdns_resolve, pass the DNS_QUERY_NO_SEARCH flag. - * - * The order of searches depends on the number of dots in the name. If the - * number is greater than the ndots setting then the names is first tried - * globally. Otherwise each search domain is appended in turn. - * - * The ndots setting can either be set from a resolv.conf, or by calling - * evdns_search_ndots_set. - * - * For example, with ndots set to 1 (the default) and a search domain list of - * ["myhome.net"]: - * Query: www - * Order: www.myhome.net, www. - * - * Query: www.abc - * Order: www.abc., www.abc.myhome.net - * - * Internals: - * - * Requests are kept in two queues. The first is the inflight queue. In - * this queue requests have an allocated transaction id and nameserver. - * They will soon be transmitted if they haven't already been. - * - * The second is the waiting queue. The size of the inflight ring is - * limited and all other requests wait in waiting queue for space. This - * bounds the number of concurrent requests so that we don't flood the - * nameserver. Several algorithms require a full walk of the inflight - * queue and so bounding its size keeps thing going nicely under huge - * (many thousands of requests) loads. - * - * If a nameserver loses too many requests it is considered down and we - * try not to use it. After a while we send a probe to that nameserver - * (a lookup for google.com) and, if it replies, we consider it working - * again. If the nameserver fails a probe we wait longer to try again - * with the next probe. - */ - -#ifndef EVENT2_DNS_H_INCLUDED_ -#define EVENT2_DNS_H_INCLUDED_ - -#include - -#ifdef __cplusplus -extern "C" { -#endif - -/* For integer types. */ -#include - -/** Error codes 0-5 are as described in RFC 1035. */ -#define DNS_ERR_NONE 0 -/** The name server was unable to interpret the query */ -#define DNS_ERR_FORMAT 1 -/** The name server was unable to process this query due to a problem with the - * name server */ -#define DNS_ERR_SERVERFAILED 2 -/** The domain name does not exist */ -#define DNS_ERR_NOTEXIST 3 -/** The name server does not support the requested kind of query */ -#define DNS_ERR_NOTIMPL 4 -/** The name server refuses to reform the specified operation for policy - * reasons */ -#define DNS_ERR_REFUSED 5 -/** The reply was truncated or ill-formatted */ -#define DNS_ERR_TRUNCATED 65 -/** An unknown error occurred */ -#define DNS_ERR_UNKNOWN 66 -/** Communication with the server timed out */ -#define DNS_ERR_TIMEOUT 67 -/** The request was canceled because the DNS subsystem was shut down. */ -#define DNS_ERR_SHUTDOWN 68 -/** The request was canceled via a call to evdns_cancel_request */ -#define DNS_ERR_CANCEL 69 -/** There were no answers and no error condition in the DNS packet. - * This can happen when you ask for an address that exists, but a record - * type that doesn't. */ -#define DNS_ERR_NODATA 70 - -#define DNS_IPv4_A 1 -#define DNS_PTR 2 -#define DNS_IPv6_AAAA 3 - -#define DNS_QUERY_NO_SEARCH 1 - -#define DNS_OPTION_SEARCH 1 -#define DNS_OPTION_NAMESERVERS 2 -#define DNS_OPTION_MISC 4 -#define DNS_OPTION_HOSTSFILE 8 -#define DNS_OPTIONS_ALL 15 - -/* Obsolete name for DNS_QUERY_NO_SEARCH */ -#define DNS_NO_SEARCH DNS_QUERY_NO_SEARCH - -/** - * The callback that contains the results from a lookup. - * - result is one of the DNS_ERR_* values (DNS_ERR_NONE for success) - * - type is either DNS_IPv4_A or DNS_PTR or DNS_IPv6_AAAA - * - count contains the number of addresses of form type - * - ttl is the number of seconds the resolution may be cached for. - * - addresses needs to be cast according to type.

The Libevent API provides a mechanism to execute a callback - function when a specific event occurs on a file descriptor or after a - timeout has been reached. Furthermore, Libevent also support callbacks due - to signals or regular timeouts. - - Libevent is meant to replace the event loop found in event driven network - servers. An application just needs to call event_base_dispatch() and then add or - remove events dynamically without having to change the event loop. - - - Currently, Libevent supports /dev/poll, kqueue(2), select(2), poll(2), - epoll(4), and evports. The internal event mechanism is completely - independent of the exposed event API, and a simple update of Libevent can - provide new functionality without having to redesign the applications. As a - result, Libevent allows for portable application development and provides - the most scalable event notification mechanism available on an operating - system. Libevent can also be used for multithreaded programs. Libevent - should compile on Linux, *BSD, Mac OS X, Solaris and, Windows. - - @section usage Standard usage - - Every program that uses Libevent must include the - header, and pass the -levent flag to the linker. (You can instead link - -levent_core if you only want the main event and buffered IO-based code, - and don't want to link any protocol code.) - - @section setup Library setup - - Before you call any other Libevent functions, you need to set up the - library. If you're going to use Libevent from multiple threads in a - multithreaded application, you need to initialize thread support -- - typically by using evthread_use_pthreads() or - evthread_use_windows_threads(). See for more - information. - - This is also the point where you can replace Libevent's memory - management functions with event_set_mem_functions, and enable debug mode - with event_enable_debug_mode(). - - @section base Creating an event base - - Next, you need to create an event_base structure, using event_base_new() - or event_base_new_with_config(). The event_base is responsible for - keeping track of which events are "pending" (that is to say, being - watched to see if they become active) and which events are "active". - Every event is associated with a single event_base. - - @section event Event notification - - For each file descriptor that you wish to monitor, you must create an - event structure with event_new(). (You may also declare an event - structure and call event_assign() to initialize the members of the - structure.) To enable notification, you add the structure to the list - of monitored events by calling event_add(). The event structure must - remain allocated as long as it is active, so it should generally be - allocated on the heap. - - @section loop Dispatching events. - - Finally, you call event_base_dispatch() to loop and dispatch events. - You can also use event_base_loop() for more fine-grained control. - - Currently, only one thread can be dispatching a given event_base at a - time. If you want to run events in multiple threads at once, you can - either have a single event_base whose events add work to a work queue, - or you can create multiple event_base objects. - - @section bufferevent I/O Buffers - - Libevent provides a buffered I/O abstraction on top of the regular event - callbacks. This abstraction is called a bufferevent. A bufferevent - provides input and output buffers that get filled and drained - automatically. The user of a buffered event no longer deals directly - with the I/O, but instead is reading from input and writing to output - buffers. - - Once initialized via bufferevent_socket_new(), the bufferevent structure - can be used repeatedly with bufferevent_enable() and - bufferevent_disable(). Instead of reading and writing directly to a - socket, you would call bufferevent_read() and bufferevent_write(). - - When read enabled the bufferevent will try to read from the file descriptor - and call the read callback. The write callback is executed whenever the - output buffer is drained below the write low watermark, which is 0 by - default. - - See for more information. - - @section timers Timers - - Libevent can also be used to create timers that invoke a callback after a - certain amount of time has expired. The evtimer_new() macro returns - an event struct to use as a timer. To activate the timer, call - evtimer_add(). Timers can be deactivated by calling evtimer_del(). - (These macros are thin wrappers around event_new(), event_add(), - and event_del(); you can also use those instead.) - - @section evdns Asynchronous DNS resolution - - Libevent provides an asynchronous DNS resolver that should be used instead - of the standard DNS resolver functions. See the - functions for more detail. - - @section evhttp Event-driven HTTP servers - - Libevent provides a very simple event-driven HTTP server that can be - embedded in your program and used to service HTTP requests. - - To use this capability, you need to include the header in your - program. See that header for more information. - - @section evrpc A framework for RPC servers and clients - - Libevent provides a framework for creating RPC servers and clients.
