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.
|
|
|
|
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.
|
|
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.

Don't reconstruct a new string for the $request_line from the parsed
method, target, and HTTP version, but rather keep a pointer to the
original memory where the request line was received.
This will be necessary for implementing URI rewrites, since we want to
log the original request line, and not one constructed from the
rewritten target.
This implementation changes behavior (only for invalid requests) in the
following way:
Previous behavior was to log as many tokens from the request line as
were parsed validly, thus:
Request -> access log ; error log
"GET / HTTP/1.1" -> "GET / HTTP/1.1" OK ; =
"GET / HTTP/1.1" -> "GET / HTTP/1.1" [1] ; =
"GET / HTTP/2.1" -> "GET / HTTP/2.1" OK ; =
"GET / HTTP/1." -> "GET / HTTP/1." [2] ; "GET / HTTP/1. [null]"
"GET / food" -> "GET / food" [2] ; "GET / food [null]"
"GET / / HTTP/1.1" -> "GET / / HTTP/1.1" [2] ; =
"GET / / HTTP/1.1" -> "GET / / HTTP/1.1" [2] ; =
"GET food HTTP/1.1" -> "GET" ; "GET [null] [null]"
"OPTIONS * HTTP/1.1" -> "OPTIONS" [3] ; "OPTIONS [null] [null]"
"FOOBAR baz HTTP/1.1"-> "FOOBAR" ; "FOOBAR [null] [null]"
"FOOBAR / HTTP/1.1" -> "FOOBAR / HTTP/1.1" ; =
"get / HTTP/1.1" -> "-" ; " [null] [null]"
"" -> "-" ; " [null] [null]"
This behavior was rather inconsistent. We have several options to go
forward with this patch:
- NGINX behavior.
Log the entire request line, up to '\r' | '\n', even if it was
invalid.
This is the most informative alternative. However, RFC-complying
requests will probably not send invalid requests.
This information would be interesting to users where debugging
requests constructed manually via netcat(1) or a similar tool, or
maybe for debugging a client, are important. It might be interesting
to support this in the future if our users are interested; for now,
since this approach requires looping over invalid requests twice,
that's an overhead that we better avoid.
- Previous Unit behavior
This is relatively fast (almost as fast as the next alternative, the
one we chose), but the implementation is ugly, in that we need to
perform the same operation in many places around the code.
If we want performance, probably the next alternative is better; if
we want to be informative, then the first one is better (maybe in
combination with the third one too).
- Chosen behavior
Only logging request lines when the request is valid. For any
invalid request, or even unsupported ones, the request line will be
logged as "-". Thus:
Request -> access log [4]
"GET / HTTP/1.1" -> "GET / HTTP/1.1" OK
"GET / HTTP/1.1" -> "GET / HTTP/1.1" [1]
"GET / HTTP/2.1" -> "-" [3]
"GET / HTTP/1." -> "-"
"GET / food" -> "-"
"GET / / HTTP/1.1" -> "GET / / HTTP/1.1" [2]
"GET / / HTTP/1.1" -> "GET / / HTTP/1.1" [2]
"GET food HTTP/1.1" -> "-"
"OPTIONS * HTTP/1.1" -> "-"
"FOOBAR baz HTTP/1.1"-> "-"
"FOOBAR / HTTP/1.1" -> "FOOBAR / HTTP/1.1"
"get / HTTP/1.1" -> "-"
"" -> "-"
This is less informative than previous behavior, but considering how
inconsistent it was, and that RFC-complying agents will probably not
send us such requests, we're ready to lose that information in the
log. This is of course the fastest and simplest implementation we
can get.
We've chosen to implement this alternative in this patch. Since we
modified the behavior, this patch also changes the affected tests.
[1]: Multiple successive spaces as a token delimiter is allowed by the
RFC, but it is discouraged, and considered a security risk. It is
currently supported by Unit, but we will probably drop support for
it in the future.
[2]: Unit currently supports spaces in the request-target. This is
a violation of the relevant RFC (linked below), and will be fixed
in the future, and consider those targets as invalid, returning
a 400 (Bad Request), and thus the log lines with the previous
inconsistent behavior would be changed.
[3]: Not yet supported.
[4]: In the error log, regarding the "log_routes" conditional logging
of the request line, we only need to log the request line if it
was valid. It doesn't make sense to log "" or "-" in case that
the request was invalid, since this is only useful for
understanding decisions of the router. In this case, the access
log is more appropriate, which shows that the request was invalid,
and a 400 was returned. When the request line is valid, it is
printed in the error log exactly as in the access log.

This makes the build tree more organized, which is good for adding new
stuff. Now, it's useful for example for adding manual pages in man3/,
but it may be useful in the future for example for extending the build
system to run linters (e.g., clang-tidy(1), Clang analyzer, ...) on the
C source code.
Previously, the build tree was quite flat, and looked like this (after
`./configure && make`):
$ tree -I src build
build
├── Makefile
├── autoconf.data
├── autoconf.err
├── echo
├── libnxt.a
├── nxt_auto_config.h
├── nxt_version.h
├── unitd
└── unitd.8
1 directory, 9 files
And after this patch, it looks like this:
$ tree -I src build
build
├── Makefile
├── autoconf.data
├── autoconf.err
├── bin
│ └── echo
├── include
│ ├── nxt_auto_config.h
│ └── nxt_version.h
├── lib
│ ├── libnxt.a
│ └── unit
│ └── modules
├── sbin
│ └── unitd
├── share
│ └── man
│ └── man8
│ └── unitd.8
└── var
├── lib
│ └── unit
├── log
│ └── unit
└── run
└── unit
17 directories, 9 files
It also solves one issue introduced in
5a37171f733f ("Added default values for pathnames."). Before that
commit, it was possible to run unitd from the build system
(`./build/unitd`). Now, since it expects files in a very specific
location, that has been broken. By having a directory structure that
mirrors the installation, it's possible to trick it to believe it's
installed, and run it from there:
$ ./configure --prefix=./build
$ make
$ ./build/sbin/unitd
Fixes: 5a37171f733f ("Added default values for pathnames.")

In BSD systems, it's usually </var/db> or some other dir under </var>
that is not </var/lib>, so $statedir is a more generic name. See

We install jars with names like websocket-api-${NXT_JAVA_MODULE}-$NXT_VERSION.jar,
which translates to versioned NXT_JAVA_MODULE in the packaging system, e.g.
websocket-api-java11-1.30.0.jar.

Also added temporary directory clearing after checking available

Previously, it was necessary to support older versions of Python for
compatibility. F-strings were released in Python 3.6. Python 3.5 was
marked as unsupported by the end of 2020, so now it's possible to start
using f-strings safely for better readability and performance.

Mutable types as default arguments is bad practice since
they are evaluated only once when the function is defined.
|
|
This allows one to simply run `./configure` and expect it to
produce sane defaults for an install.
Previously, without specifying `--prefix=...`, `make install`
would simply fail, recommending to set `--prefix` or `DESTDIR`,
but that recommendation was incomplete at best, since it didn't
set many of the subdirs needed for a good organization.
Setting `DESTDIR` was even worse, since that shouldn't even affect
an installation (it is required to be transparent to the
installation).
/usr/local is the historic Unix standard path to use for
installations from source made manually by the admin of the
system. Some package managers (Homebrew, I'm looking specifically
at you) have abused that path to install their things, but 1) it's
not our fault that someone else incorrectly abuses that path (and
they seem to be fixing it for newer archs; e.g., they started
using /opt/homebrew for Apple Silicon), 2) there's no better path
than /usr/local, 3) we still allow changing it for systems where
this might not be the desired path (MacOS Intel with hombrew), and
4) it's _the standard_.

Directory variables should never contain a trailing slash (I've
learned that the hard way, where some things would break
unexpectedly). Especially, make(1) is likely to have problems
when things have double slashes or a trailing slash, since it
treats filenames as text strings. I've removed the trailing slash
from the prefix, and added it to the derivate variables just after
the prefix. pkg-config(1) also expects directory variables to have
no trailing slash.
===
I also removed the code that would set variables as depending on
the prefix if they didn't start with a slash, because that is a
rather non-obvious behavior, and things should not always depend
on prefix, but other dirs such as $(runstatedir), so if we keep
a similar behavior it would be very unreliable. Better keep
variables intact if set, or use the default if unset.
===
Print the real defaults for ./configure --help, rather than the actual
values.
===
I used a subdirectory under the standard /var/lib for NXT_STATE,
instead of a homemade "state" dir that does the same thing.
===
Modified the Makefile to create some dirs that weren't being
created, and also remove those that weren't being removed in
uninstall, probably because someone forgot to add them.
===
Add new options for setting the new variables, and rename some to be
consistent with the standard names. Keep the old ones at configuration
time for compatibility, but mark them as deprecated. Don't keep the old
ones at exec time.
===
A summary of the default config is:

Since the previous commit, we now properly handle 403 Forbidden & 404
Not Found errors in the PHP language module.
This adds a test for 403 Forbidden to test/test_php_application.py, but
also fixes a test in test/test_php_targets.py where we were checking for
503 but should have been a 404, which we now do.

@dward on GitHub reported an issue with a URL like
http://foo.bar/test.php?blah=test.php/foo
where we would end up trying to run the script
test.php?blah=test.php
In the PHP module the format 'file.php/' is treated as a special case in
nxt_php_dynamic_request() where we check the _path_ part of the url for
the string '.php/'.
The problem is that the path actually also contains the query string,
thus we were finding 'test.php/' in the above URL and treating that
whole path as the script to run.
The fix is simple, replace the strstr(3) with a memmem(3), where we can
limit the amount of path we use for the check.
The trick here and what is not obvious from the code is that while
path.start points to the whole path including the query string,
path.length only contains the length of the _path_ part.
NOTE: memmem(3) is a GNU extension and is neither specified by POSIX or
ISO C, however it is available on a number of other systems, including:
FreeBSD, OpenBSD, NetBSD, illumos, and macOS.
If it comes to it we can implement a simple alternative for systems
which lack memmem(3).
This also adds a test case (provided by @dward) to cover this.

This patch gives users the option to set a `"prefix"` attribute
for Python applications, either at the top level or for specific
`"target"`s. If the attribute is present, the value of `"prefix"`
must be a string beginning with `"/"`. If the value of the `"prefix"`
attribute is longer than 1 character and ends in `"/"`, the
trailing `"/"` is stripped.
The purpose of the `"prefix"` attribute is to set the `SCRIPT_NAME`
context value for WSGI applications and the `root_path` context
value for ASGI applications, allowing applications to properly route
requests regardless of the path that the server uses to expose the
application.
The context value is only set if the request's URL path begins with
the value of the `"prefix"` attribute. In all other cases, the
`SCRIPT_NAME` or `root_path` values are not set. In addition, for
WSGI applications, the value of `"prefix"` will be stripped from
the beginning of the request's URL path before it is sent to the
application.
