This makes it much more clear what's what.
This is in preparation for adding WebAssembly language module support.

This commit adds the variable $response_header_NAME.
|
|
This commit is to reimplement the variables with an unknown field
such as $header_{name} to make the parsing more generic,
it's a preparation for supporting response header variables.

Almost equivalent to b42f6b1d ("Tools: unitc edit mode for interactive
configuration."), implemented by Liam in tools/unitc.
I chose to give preference to vi(1) over vim(1) because Debian has vi(1)
as part of update-alternatives(1), so that sysadmins can configure it to
be a symlink to their favourite vi(1) implementation or variant.
We're ignoring the errors of the commands due to having the SSH tunnel
open. I should fix the script to use traps to close the tunnel on any
error, so we don't leak tunnels. Then, we'll be able to not ignore
curl(1) or editor errors. That will also probably allow moving the
tunneling code to the ctl command, thus deduplicating code.

It restarts all running unitd instances. This is useful when
recompiling unitd often, so that the latest build is running, without
having to manually kill unitd instances and re-run with the same exact
command line every time.

Some ps(1) implementations trim lines to 80 columns, even if the output
is being piped. Let's force ps(1) to output full lines with `ww`, which
is not in POSIX, but seems to be portable enough.

Class usage came from the unittest framework and it was always redundant
after migration to the pytest. This commit removes classes from files
containing tests to make them more readable and understandable.

When a variable is accessed in the Unit configuration, the value is cached.
This was useful prior to the URI rewrite feature, but now that the URI (more
precisely, the request target) can be rewritten, the contents of the variable
$uri (which contains the path part of the request target, and is decoded)
should not be cached anymore, or at least the cached value should be invalidated
after a URI rewrite.
Example:
{
"rewrite": "/prefix$uri",
"share": "$uri"
}
For a request line like GET /foo?bar=baz HTTP/1.1\r\n, the expected file
served in the response would be /prefix/foo, but due to the caching issue,
Unit currently serves /foo.

Prerequisites check moved to the module level to simplify class structure.
Discovery and prerequisites checks functions moved to the separate files.
Introduced "require" fixture to provide per-test requirements check.

Improved cross-platform support by trying multiple ps(1) invocations to
obtain the unitd command line parameters. Additional error checking
detects when this process fails.
The first attempt uses `ps -wwo args=COMMAND -p` which has very broad
support and has the additional benefit of simplifying the output for
more reliable parsing of the process info. If that fails then we fall
back to simply `ps`.
The parsing of the process info has also changed. Instead of converting
'[]' into spaces we now convert them into explicit delimiters (using '^').
This is more reliable as it marks the beginning and the end of the info
we care about. Any trailing process information is now ignored (FreeBSD).
Additional error handling improves the robustness when starting unitd with
a different filename or from a relative path. In this case the control
socket and log file detection will fail when running `unitd --help`.
Additional error checking and messages are displayed when the control socket
cannot be determined. A single warning is shown when the log file cannot be
determined.

Lifespan state is a special dict in asgi lifespan scope, which allow
applications to persist data from the lifespan cycle to request/response
handling. The scope["state"] namespace provides a place to store these
sorts of things. The server will ensure that a shallow copy of the
namespace is passed into each subsequent request/response call into the
application.
Some frameworks are already taking advantage of this feature, for
example, starlette, and without this feature they wouldn't work
properly.

Common methods from applications/proto.py converted to the fixtures.
sysctl check moved to the specific file where it is using.
Some options moved to the constructor to have early access.
|
|
All log-related code moved to the log.py.
|
|
|
|
|
|
To make fixtures accessible inside of setup methods in tests all these methods
are renamed to the "setup_method_fixture" and decorated by autouse flag.
Also all setup methods moved to the top of the files.

If we don't update the pointer before copying the request body, then we
get the behavior shown below. After this patch, "foo\n" is rightly
appended at the end of the response body.
Request:
"GET / HTTP/1.1\r\nHost: _\nContent-Length: 4\n\nfoo\n"
Response body:
"""

In this case, Andrew always committed under the same name, so it's not
strictly necessary.
This is for consistency, so that it's clearer whose is an email address.
It also makes it easier to sort the names alphabetically.

We renamed the options recently, with the intention of keeping the old
names as supported but deprecated for some time, before removal. This
was done with the configure script options, but in the unitd binary, we
accidentally removed the old names, causing some unintended breakage.
Keep support for the old names, albeit with a deprecation message to
stderr, for some time, until we decide to remove them.

There are a couple of reports on GitHub about issues accessing Python
ASGI based applications over IPv6.
A request over IPv6 would result in an error like
2023/05/13 17:49:12 [alert] 47202#47202 [unit] #10: Python failed to create 'client' pair
2023/05/13 17:49:12 [alert] 47202#47202 [unit] Python failed to call 'loop.call_soon'
ValueError: invalid literal for int() with base 10: 'db8:1:1:1ee7:dead:beef:cafe'
The above error was the direct cause of the following exception:
Traceback (most recent call last):
File "/usr/lib64/python3.11/asyncio/base_events.py", line 765, in call_soon
handle = self._call_soon(callback, args, context)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/lib64/python3.11/asyncio/base_events.py", line 781, in _call_soon
handle = events.Handle(callback, args, self, context)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SystemError: <class 'asyncio.events.Handle'> returned a result with an exception set
This issue occurred in the nxt_py_asgi_create_ip_address() function
where it tries to create an IP address / port number pair.
It does this by looking for the first ':' in the address and taking
everything after it as the port number. Like in the above error message,
if we tried to access the server @ 2001:db8:1:1:1ee7:dead:beef:cafe,
then we'd end up with the port number as 'db8:1:1:1ee7:dead:beef:cafe'.
There are two issues with this
1) The IP address and port number are already flowed through
separately.
2) Even if (1) wasn't true, it would still be broken for IPv6 as we'd
expect to a get an address literal like
[2001:db8:1:1:1ee7:dead:beef:cafe]:8080, however there was no code to
handle the []'s.
The fix is to simply not try looking for a port number. We pass a port
number into this function to use in the case where we don't find a port
number, we never will...
A further cleanup would be to flow through the server port number when
creating the 'server pair' PyTuple, rather than just using the hard
coded 80.
