* at all and sends only the header and the trailer together.
* For this reason we send a trailer only if there is no a header.
*
* Although sendfile() allows to pass a header or a trailer,

/*
* All modern pthread mutex implementations try to acquire a lock
* atomically in userland before going to sleep in kernel. Some
* spins before the sleeping.
*
* In Solaris since version 8 all mutex types spin before sleeping.
* The default spin count is 1000. It can be overridden using
* _THREAD_ADAPTIVE_SPIN=100 environment variable.
*
* In MacOSX all mutex types spin to acquire a lock protecting a mutex's
* internals. If the mutex is busy, thread calls Mach semaphore_wait().
*
*
* PTHREAD_MUTEX_NORMAL lacks deadlock detection and is the fastest
* mutex type.
*
* Linux: No spinning. The internal name PTHREAD_MUTEX_TIMED_NP
* remains from the times when pthread_mutex_timedlock() was
* non-standard extension. Alias name: PTHREAD_MUTEX_FAST_NP.
* FreeBSD: No spinning.
*
*
* PTHREAD_MUTEX_ERRORCHECK is usually as fast as PTHREAD_MUTEX_NORMAL
* yet has lightweight deadlock detection.
*
* Linux: No spinning. The internal name: PTHREAD_MUTEX_ERRORCHECK_NP.
* FreeBSD: No spinning.
*
*
* PTHREAD_MUTEX_RECURSIVE allows recursive locking.
*
* Linux: No spinning. The internal name: PTHREAD_MUTEX_RECURSIVE_NP.
* FreeBSD: No spinning.
*
*
* PTHREAD_MUTEX_ADAPTIVE_NP spins on SMP systems before sleeping.
*
* Linux: No deadlock detection. Dynamically changes a spin count
* for each mutex from 10 to 100 based on spin count taken
* previously.
* FreeBSD: Deadlock detection. The default spin count is 2000.
* It can be overriden using LIBPTHREAD_SPINLOOPS environment
* variable or by pthread_mutex_setspinloops_np(). If a lock
* is still busy, sched_yield() can be called on both UP and
* SMP systems. The default yield loop count is zero, but
* it can be set by LIBPTHREAD_YIELDLOOPS environment
* variable or by pthread_mutex_setyieldloops_np().
* Solaris: No PTHREAD_MUTEX_ADAPTIVE_NP.
* MacOSX: No PTHREAD_MUTEX_ADAPTIVE_NP.
*
*
* PTHREAD_MUTEX_ELISION_NP is a Linux extension to elide locks using
* Intel Restricted Transactional Memory. It is the most suitable for
* rwlock pattern access because it allows simultaneous reads without lock.
* Supported since glibc 2.18.
*
*
* PTHREAD_MUTEX_DEFAULT is default mutex type.
*
* Linux: PTHREAD_MUTEX_NORMAL.
* FreeBSD: PTHREAD_MUTEX_ERRORCHECK.
* Solaris: PTHREAD_MUTEX_NORMAL.
* MacOSX: PTHREAD_MUTEX_NORMAL.

* Although FreeBSD sendfile() allows to pass a header and a trailer,
* it cannot send a header with a part of the file in one packet until
* FreeBSD 5.3. Besides, over the fast ethernet connection sendfile()
* may send the partially filled packets, i.e. the 8 file pages may be sent
* as the 11 full 1460-bytes packets, then one incomplete 324-bytes packet,
* and then again the 11 full 1460-bytes packets.
*
* Therefore we use the TCP_NOPUSH option (similar to Linux's TCP_CORK)
* to postpone the sending - it not only sends a header and the first part of
* the file in one packet, but also sends the file pages in the full packets.
*
* But until FreeBSD 4.5 turning TCP_NOPUSH off does not flush a pending
* data that less than MSS, so that data may be sent with 5 second delay.
* So we do not use TCP_NOPUSH on FreeBSD prior to 4.5, although it can be used
* for non-keepalive HTTP connections.

* Preallocation of first nodes : 0, 1, 00, 01, 10, 11, 000, 001, etc.
* increases TLB hits even if for first lookup iterations.
* On 32-bit platforms the 7 preallocated bits takes continuous 4K,
* 8 - 8K, 9 - 16K, etc. On 64-bit platforms the 6 preallocated bits
* takes continuous 4K, 7 - 8K, 8 - 16K, etc. There is no sense to
* to preallocate more than one page, because further preallocation
* distributes the only bit per page. Instead, a random insertion
* may distribute several bits per page.
*
* Thus, by default we preallocate maximum
* 6 bits on amd64 (64-bit platform and 4K pages)

Changes with nginx 1.9.14 05 Apr 2016
*) Feature: OpenSSL 1.1.0 compatibility.
*) Feature: the "proxy_request_buffering", "fastcgi_request_buffering",
"scgi_request_buffering", and "uwsgi_request_buffering" directives
now work with HTTP/2.
*) Bugfix: "zero size buf in output" alerts might appear in logs when
using HTTP/2.
*) Bugfix: the "client_max_body_size" directive might work incorrectly
when using HTTP/2.
*) Bugfix: of minor bugs in logging.
Changes with nginx 1.9.13 29 Mar 2016
*) Change: non-idempotent requests (POST, LOCK, PATCH) are no longer
passed to the next server by default if a request has been sent to a
backend; the "non_idempotent" parameter of the "proxy_next_upstream"
directive explicitly allows retrying such requests.
*) Feature: the ngx_http_perl_module can be built dynamically.
*) Feature: UDP support in the stream module.
*) Feature: the "aio_write" directive.
*) Feature: now cache manager monitors number of elements in caches and
tries to avoid cache keys zone overflows.
*) Bugfix: "task already active" and "second aio post" alerts might
appear in logs when using the "sendfile" and "aio" directives with
subrequests.
*) Bugfix: "zero size buf in output" alerts might appear in logs if
caching was used and a client closed a connection prematurely.
*) Bugfix: connections with clients might be closed needlessly if
caching was used.
Thanks to Justin Li.
*) Bugfix: nginx might hog CPU if the "sendfile" directive was used on
Linux or Solaris and a file being sent was changed during sending.
*) Bugfix: connections might hang when using the "sendfile" and "aio
threads" directives.
*) Bugfix: in the "proxy_pass", "fastcgi_pass", "scgi_pass", and
"uwsgi_pass" directives when using variables.
Thanks to Piotr Sikora.
*) Bugfix: in the ngx_http_sub_filter_module.
*) Bugfix: if an error occurred in a cached backend connection, the
request was passed to the next server regardless of the
proxy_next_upstream directive.
*) Bugfix: "CreateFile() failed" errors when creating temporary files on
Windows.
Changes with nginx 1.9.12 24 Feb 2016
*) Feature: Huffman encoding of response headers in HTTP/2.
Thanks to Vlad Krasnov.
*) Feature: the "worker_cpu_affinity" directive now supports more than
64 CPUs.
*) Bugfix: compatibility with 3rd party C++ modules; the bug had
appeared in 1.9.11.
Thanks to Piotr Sikora.
*) Bugfix: nginx could not be built statically with OpenSSL on Linux;
the bug had appeared in 1.9.11.
*) Bugfix: the "add_header ... always" directive with an empty value did
not delete "Last-Modified" and "ETag" header lines from error
responses.
*) Workaround: "called a function you should not call" and "shutdown
while in init" messages might appear in logs when using OpenSSL
1.0.2f.
*) Bugfix: invalid headers might be logged incorrectly.
*) Bugfix: socket leak when using HTTP/2.
*) Bugfix: in the ngx_http_v2_module.
Changes with nginx 1.9.11 09 Feb 2016
*) Feature: TCP support in resolver.
*) Feature: dynamic modules.
*) Bugfix: the $request_length variable did not include size of request
headers when using HTTP/2.
*) Bugfix: in the ngx_http_v2_module.
Changes with nginx 1.9.10 26 Jan 2016
*) Security: invalid pointer dereference might occur during DNS server
response processing if the "resolver" directive was used, allowing an
attacker who is able to forge UDP packets from the DNS server to
cause segmentation fault in a worker process (CVE-2016-0742).
*) Security: use-after-free condition might occur during CNAME response
processing if the "resolver" directive was used, allowing an attacker
who is able to trigger name resolution to cause segmentation fault in
a worker process, or might have potential other impact
(CVE-2016-0746).
*) Security: CNAME resolution was insufficiently limited if the
"resolver" directive was used, allowing an attacker who is able to
trigger arbitrary name resolution to cause excessive resource
consumption in worker processes (CVE-2016-0747).
*) Feature: the "auto" parameter of the "worker_cpu_affinity" directive.
*) Bugfix: the "proxy_protocol" parameter of the "listen" directive did
not work with IPv6 listen sockets.

possible to use the HTTP/2 protocol even if the "http2" parameter of
the "listen" directive was not specified.
*) Bugfix: in the ngx_http_v2_module.
Changes with nginx 1.9.6 27 Oct 2015
*) Bugfix: a segmentation fault might occur in a worker process when
using HTTP/2.
Thanks to Piotr Sikora and Denis Andzakovic.
*) Bugfix: the $server_protocol variable was empty when using HTTP/2.

"sub_filter" directive was used at http level; the bug had appeared
in 1.9.4.
Changes with nginx 1.9.4 18 Aug 2015
*) Change: the "proxy_downstream_buffer" and "proxy_upstream_buffer"
directives of the stream module are replaced with the
"proxy_buffer_size" directive.
*) Feature: the "tcp_nodelay" directive in the stream module.
*) Feature: multiple "sub_filter" directives can be used simultaneously.
*) Feature: variables support in the search string of the "sub_filter"
directive.

a large number of worker_connections.
*) Bugfix: a segmentation fault might occur in a worker process if the
"try_files" and "alias" directives were used inside a location given
by a regular expression; the bug had appeared in 1.7.1.
*) Bugfix: the "try_files" directive inside a nested location given by a
regular expression worked incorrectly if the "alias" directive was
used in the outer location.
*) Bugfix: in hash table initialization error handling.
*) Bugfix: nginx could not be built with Visual Studio 2015.

support kqueue NOTE_LOWAT, but also on OSes that support SO_SNDLOWAT.
*) Feature: the setproctitle() emulation for Linux and Solaris.
*) Bugfix: the "Location" header rewrite bug fixed while the proxying.
*) Bugfix: the ngx_http_chunked_module module may get caught in an
endless loop.
*) Bugfix: the /dev/poll module bugs fixed.
*) Bugfix: the responses were corrupted when the temporary files were
used while the proxying.

Изменения в nginx 1.9.14 05.04.2016
*) Добавление: совместимость с OpenSSL 1.1.0.
*) Добавление: директивы proxy_request_buffering,
fastcgi_request_buffering, scgi_request_buffering и
uwsgi_request_buffering теперь работают при использовании HTTP/2.
*) Исправление: при использовании HTTP/2 в логах могли появляться
сообщения "zero size buf in output".
*) Исправление: при использовании HTTP/2 директива client_max_body_size
могла работать неверно.
*) Исправление: незначительных ошибок логгирования.
Изменения в nginx 1.9.13 29.03.2016
*) Изменение: неидемпотентные запросы (POST, LOCK, PATCH) теперь по
умолчанию не передаются на другой сервер, если запрос уже был
отправлен на бэкенд; параметр non_idempotent директивы
proxy_next_upstream явно разрешает повторять такие запросы.
*) Добавление: модуль ngx_http_perl_module теперь можно собрать
динамически.
*) Добавление: поддержка UDP в модуле stream.
*) Добавление: директива aio_write.
*) Добавление: теперь cache manager следит за количеством элементов в
кэше и старается не допускать переполнений зоны разделяемой памяти.
*) Исправление: при использовании директив sendfile и aio с подзапросами
в логах могли появляться сообщения "task already active" и "second
aio post".
*) Исправление: при использовании кэширования в логах могли появляться
сообщения "zero size buf in output", если клиент закрывал соединение
преждевременно.
*) Исправление: при использовании кэширования соединения с клиентами
могли закрываться без необходимости.
Спасибо Justin Li.
*) Исправление: nginx мог нагружать процессор при использовании
директивы sendfile на Linux и Solaris, если отправляемый файл был
изменён в процессе отправки.
*) Исправление: при использовании директив sendfile и "aio threads"
соединения могли зависать.
*) Исправление: в директивах proxy_pass, fastcgi_pass, scgi_pass и
uwsgi_pass при использовании переменных.
Спасибо Piotr Sikora.
*) Исправление: в модуле ngx_http_sub_filter_module.
*) Исправление: если в закэшированном соединении к бэкенду происходила
ошибка, запрос передавался на другой сервер без учёта директивы
proxy_next_upstream.
*) Исправление: ошибки "CreateFile() failed" при создании временных
файлов на Windows.
Изменения в nginx 1.9.12 24.02.2016
*) Добавление: кодирование Хаффмана заголовков ответов в HTTP/2.
Спасибо Владу Краснову.
*) Добавление: директива worker_cpu_affinity теперь поддерживает более
64 процессоров.
*) Исправление: совместимость со сторонними модулями на C++; ошибка
появилась в 1.9.11.
Спасибо Piotr Sikora.
*) Исправление: nginx не собирался статически с OpenSSL на Linux; ошибка
появилась в 1.9.11.
*) Исправление: директива "add_header ... always" с пустым значением не
удаляла из заголовков ошибочных ответов строки Last-Modified и ETag.
*) Изменение: при использовании OpenSSL 1.0.2f в логах могли появляться
сообщения "called a function you should not call" и "shutdown while
in init".
*) Исправление: ошибочные заголовки могли логгироваться некорректно.
*) Исправление: утечки сокетов при использовании HTTP/2.
*) Исправление: в модуле ngx_http_v2_module.

учитывала размер заголовков запроса.
*) Исправление: в модуле ngx_http_v2_module.
Изменения в nginx 1.9.10 26.01.2016
*) Безопасность: при использовании директивы resolver во время обработки
ответов DNS-сервера могло происходить разыменование некорректного
адреса, что позволяло атакующему, имеющему возможность подделывать
UDP-пакеты от DNS-сервера, вызвать segmentation fault в рабочем
процессе (CVE-2016-0742).
*) Безопасность: при использовании директивы resolver во время обработки
CNAME-записей могло произойти обращение к ранее освобождённой памяти,
что позволяло атакующему, имеющему возможность инициировать
преобразование произвольных имён в адреса, вызвать segmentation fault
в рабочем процессе, а также потенциально могло иметь другие
последствия (CVE-2016-0746).
*) Безопасность: при использовании директивы resolver во время обработки
CNAME-записей не во всех случаях проверялось ограничение на
максимальное количество записей в цепочке, что позволяло атакующему,
имеющему возможность инициировать преобразование произвольных имён в
адреса, вызвать чрезмерное потребление ресурсов рабочими процессами
(CVE-2016-0747).
*) Добавление: параметр auto директивы worker_cpu_affinity.
*) Исправление: параметр proxy_protocol директивы listen не работал с
IPv6 listen-сокетами.
*) Исправление: при использовании директивы keepalive соединения к
бэкендам могли кэшироваться некорректно.

переменных.
*) Исправление: при использовании HTTP/2 в рабочем процессе мог
произойти segmentation fault; ошибка появилась в 1.9.6.

протокол HTTP/2 мог быть использован клиентом, даже если не был
указан параметр http2 директивы listen.
*) Исправление: в модуле ngx_http_v2_module.
Изменения в nginx 1.9.6 27.10.2015
*) Исправление: при использовании HTTP/2 в рабочем процессе мог
произойти segmentation fault.
Спасибо Piotr Sikora и Denis Andzakovic.

неожиданно завершаться по таймауту.
*) Исправление: при использовании различных настроек ssl_session_cache в
разных виртуальных серверах в рабочем процессе мог произойти
segmentation fault.

ngx_http_spdy_module).
Спасибо Dropbox и Automattic за спонсирование разработки.
*) Изменение: теперь по умолчанию директива output_buffers использует
два буфера.
*) Изменение: теперь nginx ограничивает максимальную вложенность
подзапросов, а не количество одновременных подзапросов.
*) Изменение: теперь при возврате ответов из кэша nginx проверяет ключ
полностью.
Спасибо Геннадию Махомеду и Сергею Брестеру.
*) Исправление: при использовании кэша в логах могли появляться
сообщения "header already sent"; ошибка появилась в 1.7.5.

сообщения "header already sent"; ошибка появилась в nginx 1.5.4.
*) Исправление: при использовании директивы "postpone_output 0" с
SSI-подзапросами в лог могли писаться сообщения "the http output
chain is empty".
*) Исправление: в директиве proxy_cache_lock при использовании
SSI-подзапросов.
Спасибо Yichun Zhang.
Изменения в nginx 1.7.7 28.10.2014
