2020-04-08Controller: improved handling of unix domain control socket.Valentin Bartenev5-18/+90
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: fixed cleaning up of control socket file in some cases.Valentin Bartenev1-6/+20
Previously, the unix domain control socket file might have been left in the file system after a failed nxt_listen_socket_create() call.

2020-03-27Tests: added tests for "return" action.Andrei Zeliankou4-270/+191
2020-03-27Tests: increase default "read_timeout" to 60s in message_read().Andrei Zeliankou1-1/+1
2020-03-21Implemented "location" option for "return" action.Valentin Bartenev5-2/+60
This allows to specify redirects: { "action": { "return": 301, "location": "https://www.example.com/" } }
2020-03-27Added nxt_is_complex_uri_encoded()/nxt_encode_complex_uri().Valentin Bartenev2-44/+158
2020-03-27Updated URI escaping table for better conformity with RFC 3986.Valentin Bartenev1-6/+4
Now '>', '<', '"', '^', '\', '}', '|', '{', and '`' are also escaped.
2020-03-27Implemented "return" action.Valentin Bartenev5-4/+96
The "return" action can be used to immediately generate a simple HTTP response with an arbitrary status: { "action": { "return": 404 } } This is especially useful for denying access to specific resources.
2020-03-27Initialization of the action object made more consistent.Valentin Bartenev1-3/+3
2020-03-25Tests: added tests for comments in JSON.Andrei Zeliankou1-0/+61
2020-03-25Tests: UTF-8 BOM test.Andrei Zeliankou1-0/+19
2020-03-25Configuration: fixed comments parsing.Valentin Bartenev1-1/+5
Unclosed multi-line comments and "/" at the end of JSON shouldn't be allowed.
2020-03-23Tests: increase default "read_timeout" value to 60s.Andrei Zeliankou2-15/+16
This change is necessary to avoid errors on slow hosts. Also slightly reworked argument passing to the recvall() function.
2020-03-23Tests: added notification on unsuccessful connect().Andrei Zeliankou1-1/+1
2020-03-23Tests: wait for unit.pid file before running tests.Andrei Zeliankou1-1/+4
Waiting for control.unit.sock was replaced by unit.pid due to current problem with race between connect() and listen() calls for control.unit.sock. This change should be reverted after fix.
2020-03-19Fixed filepath in the image checksum file.Konstantin Pavlov1-1/+1
2020-03-23Tests: rearranging functions in main.py.Andrei Zeliankou1-69/+69

This fixes crash introduced in 039b00e32e3d.
2020-03-19Completing request header buffers to avoid memory leak.Max Romanov3-22/+29
Before this fix, only persistent connection request buffers were completed. This issue was introduced in dc403927ab0b.

2020-03-17Fixing body fd access racing condition.Max Romanov3-18/+32
To avoid closing the body fd prematurely, the fd value is moved from the request struct to the app link. The body fd should not be closed immediately after the request is sent to the application due to possible request rescheduling.

Removing SF_NODISKIO flag for FreeBSD sendfile() check because it is not used yet and to support DragonFlyBSD. This closes #414 issue on GitHub.
