2023-04-20HTTP: added basic URI rewrite.Zhidao HONG1-4/+14
This commit introduced the basic URI rewrite. It allows users to change request URI. Note the "rewrite" option ignores the contained query if any and the query from the request is preserverd. An example: "routes": [ { "match": { "uri": "/v1/test" }, "action": { "return": 200 } }, { "action": { "rewrite": "/v1$uri", "pass": "routes" } } ] Reviewed-by: Alejandro Colomar <alx@nginx.com>
2023-04-25Allow to remove the version string in HTTP responses.Andrew Clayton1-0/+3
Normally Unit responds to HTTP requests by including a header like Server: Unit/1.30.0 however it can sometimes be beneficial to withhold the version information and in this case just respond with Server: Unit This patch adds a new "settings.http" boolean option called server_version, which defaults to true, in which case the full version information is sent. However this can be set to false, e.g "settings": { "http": { "server_version": false } }, in which case Unit responds without the version information as the latter example above shows.

2023-04-11Add per-application logging.Andrew Clayton1-0/+6
Currently when running in the foreground, unit application processes will send stdout to the current TTY and stderr to the unit log file. That behaviour won't change. When running as a daemon, unit application processes will send stdout to /dev/null and stderr to the unit log file. This commit allows to alter the latter case of unit running as a daemon, by allowing applications to redirect stdout and/or stderr to specific log files. This is done via two new application options, 'stdout' & 'stderr', e.g "applications": { "myapp": { ... "stdout": "/path/to/log/unit/app/stdout.log", "stderr": "/path/to/log/unit/app/stderr.log" } } These log files are created by the application processes themselves and thus the log directories need to be writable by the user (and or group) of the application processes. E.g $ sudo mkdir -p /path/to/log/unit/app $ sudo chown APP_USER /path/to/log/unit/app These need to be setup before starting unit with the above config. Currently these log files do not participate in log-file rotation (SIGUSR1), that may change in a future commit. In the meantime these logs can be rotated using the traditional copy/truncate method. NOTE: You may or may not see stuff printed to stdout as stdout was traditionally used by CGI applications to communicate with the webserver.

2022-12-14Python: Added "prefix" to configuration.OutOfFocus41-0/+37
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.

2022-12-13Configuration: made large_header_buffers a valid setting.Andrew Clayton1-0/+3
This is an extension to the previous commit, which made large_header_buffer_size a valid configuration setting. This commit makes a related value, large_header_buffers, a valid configuration setting. While large_header_buffer_size effectively limits the maximum size of any single header (although unit will try to pack multiple headers into a buffer if they wholly fit). large_header_buffers limits how many of these 'large' buffers are available. It makes sense to also allow this to be user set. large_header_buffers is already set by the configuration system in nxt_router.c it just isn't set as a valid config option in nxt_conf_validation.c With this change users can set this option in their config if required by the following "settings": { "http": { "large_header_buffers": 8 } }, It retains its default value of 4 if this is not set. NOTE: This is being released as undocumented and subject to change as it exposes internal workings of unit. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2022-12-13Configuration: made large_header_buffer_size a valid setting.Andrew Clayton1-0/+3
@JanMikes and @tagur87 on GitHub both reported issues with long URLs that were exceeding the 8192 byte large_header_buffer_size setting, which resulted in a HTTP 431 error (Request Header Fields Too Large). This can be resolved in the code by updating the following line in src/nxt_router.c::nxt_router_conf_create() skcf->large_header_buffer_size = 8192; However, requiring users to modify unit and install custom versions is less than ideal. We could increase the value, but to what? This commit takes the option of allowing the user to set this option in their config by making large_header_buffer_size a valid configuration setting. large_header_buffer_size is already set by the configuration system in nxt_router.c it just isn't set as a valid config option in nxt_conf_validation.c With this change users can set this option in their config if required by the following "settings": { "http": { "large_header_buffer_size": 16384 } }, It retains its default value of 8192 bytes if this is not set. With this commit, without the above setting or too low a value, with a long URL you get a 431 error. With the above setting set to a large enough value, the request is successful. NOTE: This setting really determines the maximum size of any single header _value_. Also, unit will try and place multiple values into a buffer _if_ they fully fit.

2022-12-10Isolation: wired up cgroup support to the config system.Andrew Clayton1-0/+62
This hooks the cgroup support up to the config system so it can actually be used. To make use of this in unit a new "cgroup" section has been added to the isolation configuration. e.g "applications": { "python": { "type": "python", "processes": 5, "path": "/opt/unit/unit-cgroup-test/", "module": "app", "isolation": { "cgroup": { "path": "app/python" } } } } Now there are two ways to specify the path, relative, like the above (without a leading '/') and absolute (with a leading '/'). In the above case the "python" application is placed into its own cgroup under CGROUP_ROOT/<main unit process cgroup>/app/python. Whereas if you specified say "path": "/unit/app/python" Then the python application would be placed under CGROUP_ROOT/unit/app/python The first option allows you to easily take advantage of any resource limits that have already been configured for unit. With the second method (absolute pathname) if you know of an already existing cgroup where you'd like to place it, you can, e.g "path": "/system.slice/unit/python" Where system.slice has already been created by systemd and may already have some overall system limits applied which would also apply to unit. Limits apply down the hierarchy and lower groups can't exceed the previous group limits. So what does this actually look like? Lets take the unit-calculator application[0] and have each of its applications placed into their own cgroup. If we give each application a new section like "isolation": { "cgroup": { "path": "/unit/unit-calculator/add" } } changing the path for each one, we can visualise the result with the systemd-cgls command, e.g │ └─session-5.scope (#4561) │ ├─ 6667 sshd: andrew [priv] │ ├─ 6684 sshd: andrew@pts/0 │ ├─ 6685 -bash │ ├─ 12632 unit: main v1.28.0 [/opt/unit/sbin/unitd --control 127.0.0.1:808> │ ├─ 12634 unit: controller │ ├─ 12635 unit: router │ ├─ 13550 systemd-cgls │ └─ 13551 less ├─unit (#4759) │ └─unit-calculator (#5037) │ ├─subtract (#5069) │ │ ├─ 12650 unit: "subtract" prototype │ │ └─ 12651 unit: "subtract" application │ ├─multiply (#5085) │ │ ├─ 12653 unit: "multiply" prototype │ │ └─ 12654 unit: "multiply" application │ ├─divide (#5101) │ │ ├─ 12671 unit: "divide" prototype │ │ └─ 12672 node divide.js │ ├─sqroot (#5117) │ │ ├─ 12679 unit: "sqroot" prototype │ │ └─ 12680 /home/andrew/src/unit-calculator/sqroot/sqroot │ └─add (#5053) │ ├─ 12648 unit: "add" prototype │ └─ 12649 unit: "add" application We used an absolute path so the cgroups will be created relative to the main cgroupfs mount, e.g /sys/fs/cgroup We can see that the main unit processes are in the same cgroup as the shell from where they were started, by default child process are placed into the same cgroup as the parent. Then we can see that each application has been placed into its own cgroup under /sys/fs/cgroup Taking another example of a simple 5 process python application, with "isolation": { "cgroup": { "path": "app/python" } } Here we have specified a relative path and thus the python application will be placed below the existing cgroup that contains the main unit process.

2022-10-14Configuration: stopped automatic migration to the "share" behavior.Zhidao HONG1-21/+0
This commit removed the $uri auto-append for the "share" option introduced in rev be6409cdb028.

A valid conf.json file with $uri references will end up with $uri$uri due to the auto-append.
2022-08-18Storing abstract sockets with @ internally.Alejandro Colomar1-1/+6
We accept both "\u0000socket-name" and "@socket-name" as abstract unix sockets. The first one is passed to the kernel pristine, while the second is transformed '@'->'\0'. The commit that added support for unix sockets accepts both variants, but we internally stored it in the same way, using "\u0000..." for both. We want to support abstract sockets transparently to the user, so that if the user configures unitd with '@', if we receive a query about the current configuration, the user should see the same exact thing that was configured. So, this commit avoids the transformation in the internal state file, storing user input pristine, and we only transform the '@' for a string that will be used internally (not user-visible). This commit (indirectly) fixes a small bug, where we created abstract sockets with a trailing '\0' in their name due to calling twice nxt_sockaddr_parse() on the same string. By calling that function only once with each copy of the string, we have fixed that bug.

2022-05-30Static: supporting new "index" option.Alejandro Colomar1-0/+3
This supports a new option "index" that configures a custom index file name to be served when a directory is requested. This initial support only allows a single fixed string. An example: { "share": "/www/data/static/$uri", "index": "lookatthis.htm" } When <example.com/foo/bar/> is requested, </www/data/static/foo/bar/lookatthis.html> is served. Default is "index.html". === nxt_conf_validator.c: Accept "index" as a member of "share", and make sure it's a string. === I tried this feature in my own computer, where I tried the following: - Setting "index" to "lookatthis.htm", and check that the correct file is being served (check both a different name and a different extension). - Not setting "index", and check that <index.html> is being served. - Settind "index" to an array of strings, and check that the configuration fails: { "error": "Invalid configuration.", "detail": "The \"index\" value must be a string, but not an array." }
2022-04-28Supporting variables in "location".Alejandro Colomar1-0/+1
............ Description: ............ Before this commit, the encoded URI could be calculated at configuration time. Now, since variables can only be resolved at request time, we have different situations: - "location" contains no variables: In this case, we still encode the URI in the conf structure, at configuration time, and then we just copy the resulting string to the ctx structure at request time. - "location" contains variables: In this case, we compile the var string at configure time, then when we resolve it at request time, and then we encode the string. In both cases, as was being done before, if the string is empty, either before or after resolving variables, we skip the encoding. ........... Usefulness: ........... An example of why this feature may be useful is redirecting HTTP to HTTPS with something like: "action": { "return": 301, "location": "https://${host}${uri}" } ..... Bugs: ..... This feature conflicts with the relevant RFCs in the following: '$' is used for Unit variables, but '$' is a reserved character in a URI, to be used as a sub-delimiter. However, it's almost never used as that, and in fact, other parts of Unit already conflict with '$' being a reserved character for use as a sub-delimiter, so this is at least consistent in that sense. VBart suggested an easy workaround if we ever need it: adding a variable '$sign' which resolves to a literal '$'. ...... Notes: ...... An empty string is handled as if "location" wasn't specified at all, so no Location header is sent. This is incorrect, and the code is slightly misleading. The Location header consists of a URI-reference[1], which might be a relative one, which itself might consist of an empty string[2]. [1]: <https://www.rfc-editor.org/rfc/rfc7231#section-7.1.2> [2]: <https://stackoverflow.com/a/43338457> Now that we have variables, it's more likely that an empty Location header will be requested, and we should handle it correctly. I think in a future commit we should modify the code to allow differentiating between an unset "location" and an empty one, which should be treated as any other "location" string. .................

2022-04-27Added NXT_MAYBE_UNUSED for __attribute__((__unused__)).Alejandro Colomar1-1/+2
When testing some configurations of compilers and OSes, I noticed that clang(1) 13 on Debian caused a function to be compiled but unused, and the compiler triggered a compile error. To avoid that error, use __attribute__((__unused__)). Let's call our wrapper NXT_MAYBE_UNUSED, since it describes itself more precisely than the GCC attribute name. It's also the name that C2x (likely C23) has given to the standard attribute, which is [[maybe_unused]], so it's also likely to be more readable because of that name being in ISO C.

2021-08-17Added TLS session tickets support.Andrey Suvorov1-0/+73
2021-08-12Router: client IP address replacement.Oisin Canty1-0/+25
This commit introduces the replacement of the client address based on the value of a specified HTTP header. This is intended for use when Unit is placed behind a reverse proxy like nginx or a CDN. You must specify the source addresses of the trusted proxies. This can be accomplished with any valid IP pattern supported by Unit's match block: ["10.0.0.1", "10.4.0.0/16", "!192.168.1.1"] The feature is configured per listener. The client address replacement functionality only operates when there is a source IP match and the specified header is present. Typically this would be an 'X-Forwarded-For' header. { "listeners": { "127.0.0.1:8080": { "client_ip": { "header": "X-Forwarded-For", "source": [ "10.0.0.0/8" ] }, "pass": "applications/my_app" }, } } If a request occurs and Unit receives a header like below: "X-Forwarded-For: 84.123.23.23" By default, Unit trusts the last rightmost IP in the header, so REMOTE_ADDR will be set to 84.123.23.23 if the connection originated from 10.0.0.0/8. If Unit runs behind consecutive reverse proxies and receives a header similar to the following: "X-Forwarded-For: 84.123.23.23, 10.0.0.254" You will need to enable "recursive" checking, which walks the header from last address to first and chooses the first non-trusted address it finds. { "listeners": { "127.0.0.1:8080": { "client_ip": { "header": "X-Forwarded-For", "source": [ "10.0.0.0/8" ] "recursive": true, }, "pass": "applications/my_app" }, } } If a connection from 10.0.0.0/8 occurs, the chain is walked. Here, 10.0.0.254 is also a trusted address so the client address will be replaced with 84.123.23.23. If all IP addresses in the header are trusted, the client address is set to the first address in the header: If 10.0.0.0/8 is trusted and "X-Forwarded-For: 10.0.0.3, 10.0.0.2, 10.0.0.1", the client address will be replaced with 10.0.0.3.

An example of configuration: { "type": "ruby", "processes": 2, "threads": 2, "user": "vagrant", "group": "vagrant", "script": "config.ru", "hooks": "hooks.rb", "working_directory": "/home/vagrant/unit/rbhooks", "environment": { "GEM_HOME": "/home/vagrant/.ruby" } } An example of a valid "hooks.rb" file follows: File.write("./hooks.#{Process.pid}", "hooks evaluated") on_worker_boot do File.write("./worker_boot.#{Process.pid}", "worker booted") end on_thread_boot do File.write("./thread_boot.#{Process.pid}.#{Thread.current.object_id}", "thread booted") end on_thread_shutdown do File.write("./thread_shutdown.#{Process.pid}.#{Thread.current.object_id}", "thread shutdown") end on_worker_shutdown do File.write("./worker_shutdown.#{Process.pid}", "worker shutdown") end This closes issue #535 on GitHub.
2021-05-26Enabling SSL_CTX configuration by using SSL_CONF_cmd().Andrey Suvorov1-0/+46
To perform various configuration operations on SSL_CTX, OpenSSL provides SSL_CONF_cmd(). Specifically, to configure ciphers for a listener, "CipherString" and "Ciphersuites" file commands are used: https://www.openssl.org/docs/man1.1.1/man3/SSL_CONF_cmd.html This feature can be configured in the "tls/conf_commands" section.

2020-11-17HTTP parser: allowed more characters in header field names.Valentin Bartenev1-0/+3
Previously, all requests that contained in header field names characters other than alphanumeric, or "-", or "_" were rejected with a 400 "Bad Request" error response. Now, the parser allows the same set of characters as specified in RFC 7230, including: "!", "#", "$", "%", "&", "'", "*", "+", ".", "^", "`", "|", and "~". Header field names that contain only these characters are considered valid. Also, there's a new option introduced: "discard_unsafe_fields". It accepts boolean value and it is set to "true" by default. When this option is "true", all header field names that contain characters in valid range, but other than alphanumeric or "-" are skipped during parsing. When the option is "false", these header fields aren't skipped. Requests with non-valid characters in header field names according to RFC 7230 are rejected regardless of "discard_unsafe_fields" setting. This closes #422 issue on GitHub.
