2018-10-22Improved epoll failures handling.Igor Sysoev2-12/+13
epoll changes are committed to the kernel before epoll_wait() or on changes array overflow. In the latter case if there are errors epoll_wait() timeout was not set to zero. This commit is related to #173 issue on GitHub. Thanks to 洪志道 (Hong Zhi Dao).
2018-10-22Removed duplicate code in epoll.Igor Sysoev1-9/+0
This commit is related to #173 issue on GitHub. Thanks to 洪志道 (Hong Zhi Dao).
2018-10-22Handling of timers with bias.Valentin Bartenev5-23/+30
Timers that don't require maximum precision (most of them, actually) can be triggered earlier or later within the bias interval. To reduce wakeups by timers, the expire function now triggers not only all timers that fall within the elapsed time, but also those whose bias falls within this interval.
2018-10-22Timers: separation of delete and insert operations on rbtree.Valentin Bartenev1-10/+20
Delete/insert operation complexity for a red-black tree is O(log n), where n is the total number of tree elements. If all delete operations are performed before all insert operations, the average number of tree elements during an operation will be lower than in the mixed-operations case.
2018-10-22Re-engineered timers.Valentin Bartenev3-97/+78
To optimize rbtree operations, all changes are stored in array and later processed in batches. The previous implementation of this mechanics had a number of design flaws. Each change was saved in a new array entry; until the changes were applied, the timer remained in an intermediate state (NXT_TIMER_CHANGING). This intermediate state didn't allow to identify if time was going to be disabled or enabled. However, the nxt_conn_io_read() function relied on this information; as a result, in some cases the read timeout wasn't set. Also, the nxt_timer_delete() function did not reliably track whether a timer was added to the work queue. It checked the NXT_TIMER_ENQUEUED state of a timer, but this state could be reset to NXT_TIMER_DISABLED by a nxt_timer_disable() call or another nxt_timer_delete() call. Now, instead of keeping the whole history of the timer's changes, the new implementation updates the timer state immediately, and only one operation is added to the array to add or delete timer in the rbtree according to its final state.
2018-10-22Compatibility with LibreSSL.Sergey Kandaurov1-1/+1
LibreSSL uses high OPENSSL_VERSION_NUMBER, but has no SSL_CTX_add0_chain_cert().
2018-10-18Tests: provide openssl.conf in test_tls_certificate_key_ec.Sergey Kandaurov1-0/+3
Previously, test failed if openssl was unable to load config info, or the system's openssl.cnf was picked up, which is wrong as well.

2018-10-09Renamed "go" application type to "external".Valentin Bartenev17-88/+91
There's nothing specific to Go language. This type of application object can be used to run any external application that utilizes libunit API.
2018-10-05Packages: all CRLF newlines in examples converted to LF.Andrei Belov6-126/+126

2018-10-02Making port fd blocking on app side and non-blocking in Unit.Max Romanov2-1/+12
This issue was introduced in libunit commit (e0f0cd7d244a). All port sockets in application should be in blocking mode whereas Unit itself operates non-blocking sockets. Having non-blocking sockets in application may cause send error during intensive response packets generation. See https://mailman.nginx.org/pipermail/unit/2018-October/000080.html.
2018-10-01Disabled chunked transfer encoding for 304 responses as well.Valentin Bartenev1-1/+1
According to RFC 7232: | A 304 response cannot contain a message-body; it is always terminated | by the first empty line after the header fields.
2018-10-01Allowing keep-alive connections after 204 responses.Valentin Bartenev1-5/+7
This was unintentionally disabled by 7b5026a0bdeb.
2018-10-01Fixed error log time caching resolution.Valentin Bartenev1-1/+1
Thanks to 洪志道 (Hong Zhi Dao).
2018-10-01Mention of --openssl configure option in help.Valentin Bartenev1-0/+2
This closes #171 issue on GitHub. Thanks to 洪志道 (Hong Zhi Dao).
2018-10-01Skipping minor entries while producing generic CHANGES.Andrei Belov2-0/+10
Currently we consider any changes with revision other than 1 as packages-specific, thus there is no need to include such entries to the generic Unit change log.

2018-09-20Resetting init->stream for ready process.Max Romanov1-0/+4
Router requests application start by sending port message with application parameters to master. In response router gets application port. Stream id used to link request and response. If application process terminates unexpectedly (e.g. before ready state), it is required to notify router about application start failure. For this purpose stream id is stored in process initialization parameters. Stream id sequentially incremented and starts from 1 in case of router resurrection. New router application start stream id may coincide with stream id of currently running/terminating application processes. In such cases router may receive REMOVE_PID message with same stream id as used in application start request and mistakenly reports application start failure. This commit tries to avoid such errors by resetting stream for processes in ready state.

_GNU_SOURCE is required there to expose off64_t and other types.
2018-09-20Preventing port from release in asynchronous operations.Max Romanov1-0/+12
Router reconfiguration may lead to starting new application processes, opening listen ports etc. These actions are asynchronous and require message exchange with master process. Router stores reference for controller (response) port in structure associated with reconfiguration process (tmcf). The port used to provide reconfiguration response (either success or failed) to controller. This commit increases response port use counter to make sure port structure not freed while router waits for result of asynchronous operations.
2018-09-20Packages: enabled OpenSSL support.Andrei Belov4-7/+13
2018-09-20Python: adjusted input.read(size) argument value interpretation.Valentin Bartenev2-4/+5
Previously, passing 0 resulted in reading the whole body and all negative values raised an exception. Now the behaviour is in consistentance with io.RawIOBase.read() interface, and passing 0 returns empty (byte) string, while -1 results in reading the whole body.
