2020-10-06PHP: compatibility with 8.0.0 RC1.Valentin Bartenev1-0/+30
This closes #474 PR on GitHub.
2020-10-07Router: fixed "not empty" pattern matching.Valentin Bartenev1-4/+0
The "!" pattern should be opposite to "", i.e. match only non-empty values. But after 3c00af54b937 it was equal to "!*", which is wrong.
2020-10-06Removing a meaningless warning message.Max Romanov1-4/+0
Data in the queue and the socket are transmitted independently; special READ_QUEUE and READ_SOCKET message types are used for synchronization. The warning was accidentally committed with changeset 1d84b9e4b459.
2020-10-02Fixed comment.Igor Sysoev1-1/+1
Thanks to 洪志道 (Hong Zhi Dao).
2020-10-01Python: ASGI server introduced.Max Romanov10-29/+3723
This closes #461 issue on GitHub.
2020-10-01Publishing libunit's malloc() and free() wrappers for apps.Max Romanov2-49/+57
2020-09-09PHP: fixed "rootfs" isolation dependency on system mounts.Tiago Natel de Moura1-55/+107
2020-09-30Fixing router connection pool leakage.Max Romanov1-1/+4
The connection's local socket address is allocated from the connection pool before the request is passed to the application; however, with keep-alive connections, this field was unconditionally reset by a socket configuration value that could be NULL. For the next request, the address was allocated again from the same connection pool. Nonetheless, all leaked addresses were released when the connection was closed. The issue introduced in changeset 5c7dd85fabd5.
2020-09-30Fixing leakage caused by incorrect in_hash flag cleanup.Max Romanov1-1/+3
Large-bodied requests are added to the request hash to be found when the body arrives. However, changeset 1d84b9e4b459 introduced a bug: the 'in_hash' flag, used to remove the request from the hash at request release, was cleared after the first successful request lookup. As a result, the entry was never removed.
2020-09-29MIME: added AVIF and APNG image formats.Valentin Bartenev1-1/+4
AVIF is a modern image format based on the AV1 video codec. It generally has better compression than other widely used formats (WebP, JPEG, PNG, and GIF) and is designed to supersede them. Support was already added to the latest version of Chrome. APNG extends PNG to permit animated images that work similarly to animated GIF. It's supported by most modern browsers. Also removed duplicated ".svg" entry.
2020-09-29Wrapping libunit's malloc() and free() calls for logging purposes.Max Romanov3-65/+98
This change aids heap usage analysis in applications. The alloc and free functions are also required for lvlhash due to the upcoming threading support, because using main nxt_memalign() and nxt_free() isn't safe in a multithreaded app environment. The reason is that these functions may use thread-local structures which aren't initialized properly in applications.
2020-09-29Fixing request buffer memory leakage in router.Max Romanov1-0/+3
The issue was introduced in changeset 1d84b9e4b459. The request buffer was transferred via the shared application queue, but the buffer position and the 'sent' flag were not updated after the buffer had been sent.
2020-09-29Supporting HTTP/1.0 keep-alive.Max Romanov1-1/+8
The Apache HTTP server benchmarking tool, ab, issues HTTP/1.0 requests with the 'Connection: Keep-Alive' header and expects a 'Connection: Keep-Alive' header in the response.
2020-09-18Updated racially charged language in messages and comments.Artem Konev2-4/+4
2020-09-18Python: app module callable name configuration.Max Romanov4-5/+21
Now it is possible to specify the name of the application callable using optional parameter 'callable'. Default value is 'application'. This closes #290 issue on GitHub.
2020-09-18Fixed segmentation fault during reconfiguration.Igor Sysoev1-7/+3
If idle connection was closed before h1proto had been allocated then c->socket.data is NULL. This happens if nxt_h1p_idle_response() is called by nxt_h1p_idle_close(). However, h1p->conn_write_tail is used only in nxt_h1p_request_send() that would not be called after nxt_h1p_idle_response(). The bug was introduced in f237e8c553fd.
2020-09-18Fixed segmentation fault during reconfiguration.Igor Sysoev1-1/+9
2020-09-18Fixed use-after-free error during reconfiguration.Igor Sysoev1-0/+2
An idle connection was not removed from idle connection list if the connections detected that listening socket had been closed.
2020-08-28Router: fixed "pass" to upstreams.hongzhidao3-3/+11
Messed up return values in nxt_upstream_find() caused error in applying any configuration with a valid "pass" value in router configuration pointing to upstream. That wasn't the case in "listeners" objects, where the return value wasn't checked. Also, it caused segfault in cases where the "pass" option was configured with variables and resulting value was pointing to a non-existent upstream. Added missing return checks as well to catch possible memory allocation errors. The bug was introduced in d32bc428f46b. This closes #472 issue on GitHub.
2020-09-16Isolation: remove redundant macro.Tiago Natel de Moura2-4/+1
2020-09-15Python: changed request headers format in router protocol.Max Romanov2-11/+107
The coming ASGI support requires raw HTTP headers format. Headers grouping and upcase code were moved to WSGI module.
2020-09-15Hardening header names comparation for grouping.Max Romanov1-10/+67
2020-09-14Python: split module initialization from WSGI implementation.Max Romanov3-285/+387
This is required for futher ASGI implementation.
2020-09-14Python: source file moved to 'python' sub-directory.Max Romanov1-0/+0
No functional changes. Get ready for an increase in file number.
2020-09-10Fixing WebSocket frame retain function.Max Romanov1-2/+13
Some of the pointers were not adjusted after frame's memory re-allocation. Fortunately, this function was not used and the bug has no effect.
2020-09-07Upstream connection was not closed for short chunked response.Igor Sysoev1-27/+3
2020-08-28Vars: added $host.Valentin Bartenev1-0/+20
This closes #407 issue on GitHub.
2020-08-25Isolation: added "automount" option.Tiago Natel de Moura5-20/+98
Now it's possible to disable default bind mounts of languages by setting: { "isolation": { "automount": { "language_deps": false } } } In this case, the user is responsible to provide a "rootfs" containing the language libraries and required files for the application.
2020-08-25PHP: added bind mounts for extensions directory.Tiago Natel de Moura1-2/+4
2020-08-21Configuration: removed "reschedule_timeout" option.Valentin Bartenev3-18/+0
It's not used since cbcd76704c90. This option is a leftover from previous IPC between router and applications processes. It was never documented, though. Thanks to 洪志道 (Hong Zhi Dao).
2020-08-20Isolation: mount tmpfs by default.Tiago Natel de Moura5-66/+155
2020-08-20Moved isolation related code to "nxt_isolation.c".Tiago Natel de Moura6-980/+989
2020-08-19Configuration: improved error message of invalid listener address.Valentin Bartenev1-2/+9
Thanks to 洪志道 (Hong Zhi Dao). This closes #466 issue on GitHub.
2020-08-17Supporting platforms without sendfile() implementation.Max Romanov1-1/+18
This is a quick and dirty sendfile() replacement. This closes #452 PR on GitHub.
2020-08-17Style: changing preprocessor directives.Max Romanov1-5/+11
Using #if directives instead of #ifdef the same way as in other places.
2020-08-13Fixing router assertion in result of application prefork error.Max Romanov1-0/+8
Buffer for application prefork request allocated from temp conf mem_pool. If error response from main process received before buffer completion handler, temp conf mem_pool destroyed and router may crash in completion handler. Assertion "src/nxt_buf.c:208 assertion failed: data == b->parent" triggered when NXT_DEBUG_ALLOC enabled in configure. This patch disables completion handler and memory allocated for buffer released with memory pool.
2020-08-13Fixed error handling of prefork callback.Tiago Natel de Moura1-14/+21
Previously, an error during the prefork phase triggered assert: src/nxt_port.c:27 assertion failed: port->pair[0] == -1 and resulted in exiting of the main process. This could be easily reproduced by pushing a configuration with "rootfs", when daemon is running without required permissions.
2020-08-13Fixed typo in return value check.Valentin Bartenev1-1/+1
Found by Coverity (CID 361277).
2020-08-13Basic variables support.Valentin Bartenev18-144/+1084
2020-08-12PHP: compatibility with 8.0.0 Beta 1.Remi Collet1-1/+15
This closes #441 PR on GitHub.
2020-08-12Responding with error in case of first process start failure.Max Romanov3-18/+129
After shared application port introducing, request queue in router was removed and requests may stuck forever waiting for another process start.
2020-08-12Fixing issues found by static analyzer.Max Romanov1-2/+4
2020-08-11Fixing return value initialization.Max Romanov1-19/+25
2020-08-11Style fixes for 2 file descriptors transfer over port.Max Romanov7-110/+115
Two consecutive fd and fd2 fields replaced with array.
2020-08-11Moving file descriptor blocking to libunit.Max Romanov3-19/+39
The default libunit behavior relies on blocking the recv() call for port file descriptors, which an application may override if needed. For external applications, port file descriptors were toggled to blocking mode before the exec() call. If the exec() call failed, descriptor remained blocked, so the process hanged while trying to read from it. This patch moves file descriptor mode switch inside libunit.
2020-08-11Wrapping close() call in libunit for logging.Max Romanov1-35/+44
2020-08-11Introducing application and port shared memory queues.Max Romanov11-311/+1793
The goal is to minimize the number of syscalls needed to deliver a message.
2020-08-11Circular queues implementations and a test.Max Romanov3-0/+886
- naive circular queue, described in the article "A Scalable, Portable, and Memory-Efficient Lock-Free FIFO Queue" by Ruslan Nikolaev: https://drops.dagstuhl.de/opus/volltexte/2019/11335/pdf/LIPIcs-DISC-2019-28.pdf - circular queue, proposed by Valentin Bartenev in the "Unit router application IPC" design draft
2020-08-11Port message extended to transfer 2 file descriptors.Max Romanov5-27/+81
2020-08-11Made router port message handlers into static functions.Max Romanov2-10/+13
Mostly harmless.
