2017-12-27Implementing worker stop after limits.requests.Max Romanov2-4/+14
2017-12-27Rescheduling of pending request after configured timeout.Max Romanov4-88/+222
New optional configuration parameter introduced: limits.reschedule_timeout. Default value 1 second. In the case when request is written to the port socket 'in advance', it is called 'pending'. On every completed request, the head of pending request is checked against reschedule timeout. If this request waiting for execution longer than timeout, it is cancelled, new port selected for this request.
2017-12-27Fixing code style.Max Romanov1-16/+16
2017-12-27Fixing application timeout.Max Romanov4-107/+362
Application timeout limits maximum time of worker response in processing particular request. Not including the time required to start worker, time in request queue etc.
2017-12-27Changing worker selection precedence.Max Romanov2-23/+48
This patch increase precedence of non-started worker over busy worker. 1. idle worker; 2. start new worker; 3. busy worker, but can accept request in advance;
2017-12-27Implementing the ability to cancel request before worker starts processing it.Max Romanov14-357/+542

2017-12-27Introducing application 'atexit' hook.Max Romanov7-5/+36
Finalizing Python interpreter. This closes #65 issue on GitHub.
2017-12-26nxt_conn_close() should disable all pending write operations.Igor Sysoev1-0/+6
2017-12-26HTTP parser: fixed memory overflow in the collisions test.Valentin Bartenev1-0/+1
The level hash uses the NULL value as the indicator of a free entry in a bucket. So, inserting a NULL value breaks the hash and can lead to a bucket overflow. In case of the collision counter, the value wasn't initialized, since it's not needed for the purpose of checking collisions. As a result, it might contain any garbage from the stack and in some rare cases the value was NULL. Now the value is initilized.
2017-12-25HTTP parser: reworked header fields handling.Valentin Bartenev7-427/+445
2017-12-25Restoring apps in case of reconfiguration error.Max Romanov1-0/+3
2017-12-13Introducing Unit version check in Go package.Max Romanov4-65/+122
To communicate with the Go program, Unit setup environment variable named NXT_GO_PORTS with value contains Unit version, stream id to confirm application is started, and Unit ports information. Go Unit package parses this string and compares runtime version with compile time version. In case of parse error or version mismatch, ListenAndServe() returns with the error.

2017-12-08HTTP parser: slightly improved readability of code.Valentin Bartenev1-103/+101
As suggested by Igor Sysoev.
2017-12-07Fixed protocol version string handling in router.Valentin Bartenev1-1/+1
2017-12-06Go: removing request registry.Max Romanov11-244/+96
Passing unsafe.Pointers (void *) from Go to C is complicated by an attempt to make such pointers less unsafe. A straightforward optimization is to replace 'unsafe.Pointer' with 'uintptr' (thanks to Xin Huang for the idea: https://stackoverflow.com/a/44826533 ). As a result, request registry with mutex is gone.
2017-12-05Fixing Go package build in NetBSD.Max Romanov1-1/+1
Bug introduced in 585c8068a6d7.
2017-12-01Making Go package source distributable and renaming to 'nginx/unit'.Max Romanov8-85/+34
All header files are copied to Go package sources. As the result, package can be (re-)build when required. This closes #23 issue on GitHub.

2017-11-29Introducing python virtualenv configuration.Max Romanov4-0/+44
New parameter 'home' for python application allows to configure application-specific virtualenv path. This closes #15 issue on GitHub.

2017-10-27Fixing racing condition in request.msgs usage.Max Romanov1-8/+8
2017-10-27Fixing Go program crash.Max Romanov1-2/+2
Go request registration should be removed before C request memory freed. C request address used as a key in Go map. Freed memory can be instantly reused for other request and older request registration should removed at this point to avoid collisions.
2017-10-25Checking the result of shared memory buffer allocation.Max Romanov1-0/+3
This closes #57 issue on GitHub.

2017-10-19Fixed controller restarting.Valentin Bartenev2-24/+38
Previously, stored configuration wasn't reread on controller process restart, which resulted in segmentation fault.
2017-10-19Keep application worker until response for all requests received.Max Romanov1-1/+4
2017-10-19Filtering process to keep connection.Max Romanov5-13/+58
- Main process should be connected to all other processes. - Controller should be connected to Router. - Router should be connected to Controller and all Workers. - Workers should be connected to Router worker thread ports only. This filtering helps to avoid unnecessary communication and various errors during massive application workers stop / restart.
2017-10-19Introducing mmap_handler to count references to shared memory.Max Romanov3-87/+146
"All problems in computer science can be solved by another level of indirection" Butler Lampson Completion handlers for application response buffers executed after sending the data to client. Application worker can be stopped right after send response buffers to router. Worker stop causes removal of all data structures for the worker. To prevent shared memory segment unmap, need to count the number of buffers which uses it. So instead of direct reference to shared memory, need to reference to intermediate 'handler' structure with use counter and pointer to shared memory.
2017-10-19Supporting concurrent shared memory fd receive in router.Max Romanov6-104/+86
Two different router threads may send different requests to single application worker. In this case shared memory fds from worker to router will be send over 2 different router ports. These fds will be received and processed by different threads in any order. This patch made possible to add incoming shared memory segments in arbitrary order. Additionally, array and memory pool are no longer used to store segments because of pool's single threaded nature. Custom array-like structure nxt_port_mmaps_t introduced.
2017-10-19Introducing src_pid for mmap header for accurate buf completion.Max Romanov3-16/+30
This allows to use shared memory to communicate with main process. This patch changes shared memory segment format and breaks compatibility with older modules.
