2020-05-12Waiting for router instead of reporting to user on config update.Max Romanov1-24/+25
2020-05-12Blocking config change when applying the initial router config.Max Romanov1-11/+32
2020-04-16Using malloc/free for the http fields hash.Max Romanov1-4/+1
This is required due to lack of a graceful shutdown: there is a small gap between the runtime's memory pool release and router process's exit. Thus, a worker thread may start processing a request between these two operations, which may result in an http fields hash access and subsequent crash. To simplify issue reproduction, it makes sense to add a 2 sec sleep before exit() in nxt_runtime_exit().
2020-04-08Controller: improved handling of unix domain control socket.Valentin Bartenev1-1/+1
One of the ways to detect Unit's startup and subsequent readiness to accept commands relies on waiting for the control socket file to be created. Earlier, it was unreliable due to a race condition between the client's connect() and the daemon's listen() calls after the socket's bind() call. Now, unix domain listening sockets are created with a nxt_listen_socket_create() call as follows: s = socket(); unlink("path/to/socket.tmp") bind(s, "path/to/socket.tmp"); listen(s); rename("path/to/socket.tmp", "path/to/socket"); This eliminates a time-lapse when the socket file is already created but nobody is listening on it yet, which therefore prevents the condition described above. Also, it allows reliably detecting whether the socket is being used or simply wasn't cleaned after the daemon stopped abruptly. A successful connection to the socket file means the daemon has been started; otherwise, the file can be overwritten.

2020-04-08Controller: eliminated extra control socket's sockaddr copying.Valentin Bartenev1-11/+1
2020-02-20Configuration: removing UTF-8 BOM from the input JSON.Valentin Bartenev1-0/+7

It allows to add an array element without specifying the index.

2018-04-26Controller waits READY message from router.Max Romanov1-14/+47
This required to avoid racing condition when controller receive router port before router receives controller port.

2017-12-25HTTP parser: reworked header fields handling.Valentin Bartenev1-24/+22
2017-11-27A number of engine connections is decreased on connection close.Igor Sysoev1-3/+1
2017-10-25Checking the result of shared memory buffer allocation.Max Romanov1-0/+3
This closes #57 issue on GitHub.
2017-10-18Router: fixed segfault after configuration change.Igor Sysoev1-1/+1
2017-10-10Basic validation errors.Valentin Bartenev1-18/+67
2017-10-04Using port 'post' facility to proxy remove pid message to workers.Max Romanov1-1/+1
Remove pid proxying to worker engines implementation was originally overcomplicated. Memory pool and 2 engine posts (there and back again) are optimized out and replaced with band new nxt_port_post() call.
2017-10-04Using engine memiory pool for port write allocations.Max Romanov1-1/+1
To allow use port from different threads, the first step is to avoid using port's memory pool for temporary allocations required to send data through the port. Including but not limited by: - buffers for data; - send message structures; - new mmap fd notifications; It is still safe to use port memory pool for incoming buffers allocations because recieve operation bound to single thread.
2017-09-27Event engine memory cache for nxt_sockaddr_t.Igor Sysoev1-0/+10
Introducing event engine memory cache and using the cache for nxt_sockaddr_t structures.

2017-09-10Configuration persistence.Valentin Bartenev1-0/+87
Now configuration survives server reloads.
2017-09-14Fixed textual socket name lengths and Unix domain sockaddr length.Igor Sysoev1-3/+2
2017-08-31nginext has been renamed to unit.Igor Sysoev1-2/+2
2017-08-30Controller: resending configuration to router after its restart.Valentin Bartenev1-66/+116
Now router crash can be survived with less damage.
2017-08-30Controller: waiting for router before start to accept connections.Valentin Bartenev1-12/+48
Previously, reconfiguration might fail right after the daemon start if the router process wasn't ready yet.
2017-08-30Controller: correct handling of missing router port.Valentin Bartenev1-11/+41
There's no router port if the router process is just crashed or hasn't started yet.
2017-08-29The master process has been renamed to the main process.Igor Sysoev1-1/+1
2017-08-28Improved reconfiguration requests serialization.Valentin Bartenev1-81/+49
Previously, only applying of updated configuration was serialized, while the changes themselves could be done in parallel on the same configuration. That resulted in inconsistent behaviour.
2017-08-26Added configure and command line option --control.Igor Sysoev1-16/+0
2017-08-13Fixed building by GCC after 7d1017bd0f6c.Valentin Bartenev1-1/+1
2017-08-11Controller: more HTTP headers and detailed JSON parsing errors.Valentin Bartenev1-116/+238
2017-08-04Fixed building without debug after c1ae75b4e17c and 6281674ecf4f.Valentin Bartenev1-6/+2
2017-08-02Using port rpc in controller->router configuration update.Max Romanov1-10/+24
2017-08-02Added bit flags to type parameter of nxt_port_socket_write().Max Romanov1-1/+2
NXT_PORT_MSG_LAST - mark message as last; NXT_PORT_MSG_CLOSE_FD - close fd right after send; Type constants altered to include last flag for single buffer messages. Last sign is critical for coming port RPC layer. Handlers unregistered on last message. Create sync buffer is not convenient, extra parameter is better.
2017-07-21Fixed building without debug.Valentin Bartenev1-4/+2
2017-07-12New process port exchange changed. READY message type introduced.Max Romanov1-8/+5
Application process start request DATA message from router to master. Master notifies router via NEW_PORT message after worker process become ready.
2017-07-12Controller: proper reconfiguration requests handling.Valentin Bartenev1-43/+136
Now controller serializes all reconfiguration requests and waits for result from router.
