When processing a restart request, the router sends a QUIT message to all
existing processes of the application. Then, a new shared application port is
created to ensure that new requests won't be handled by the old processes of
the application.
A race may occur between the router process restart and the main process
sending a notification to the running controller. For example, a test script
detects the new process and starts performing a smoke test, but the controller
has not yet received the 'remove PID' notification, so the connection to the
router is broken and any attempt to update the configuration will cause an
error.
The solution is to perform several attempts to reconfigure Unit with a short
delay between failures.
Because of the incorrect 'last' field assignment, multiple listeners with
a TLS certificate did not initialize properly, which caused a router crash
while establishing a connection.
Test with multiple TLS listeners added.
The issue was introduced in the c548e46fe516 commit.
This closes#561 issue on GitHub.
In Go 1.16, the module-aware mode is enabled by default; to fall back to
previous behavior, the GO111MODULE environment variable should be set to
'auto'.

Also added stubs for Server.address()
This was done to prevent crashes in some popular frameworks like express
Supports both CommonJS and the new ES Modules system syntax e.g:
app.js:
const http = require('http')
app.mjs:
import http from "http"
Usage on Node 14.16.x and higher:
{
"type": "external",
"processes": {"spare": 0},
"working_directory": '/project',
"executable": "/usr/bin/env",
"arguments": [
"node",
"--loader",
"unit-http/require_shim.mjs"
"--require",
"unit-http/require_shim",
"app.js"
]
}
Usage on Node 14.15.x and lower:
{
"type": "external",
"processes": {"spare": 0},
"working_directory": '/project',
"executable": "/usr/bin/env",
"arguments": [
"node",
"--require",
"unit-http/require_shim",
"app.js"
]
}
Introducing "unit.log.Log" class for "unit.log" file management.
Moving "findall()" function into TestApplicationProto.
Using "os.kill()" to send signals.
Test case: "send a text message split into two fragments, then a continuation
frame with FIN = false where there is nothing to continue, then an unfragmented
text message, all sent in one chop".
The test case investigates immediate connection closing since there is no
message to continue.
The mirror server may send a response for the first frame before the test
сontinuation frame is received by the router. In this case, the test will
receive a text frame before the close frame.
After WebSocket processing, the application port was released with incorrect
reason ("got request"), unnecessarily decrementing the active request counter.
The assertion was triggered only on application removal; a test was added
for this case.
