2025-08-09[mod] limiter: trusted proxies (#4911)Ivan Gabaldon
Replaces `x_for` functionality with `trusted_proxies`. This allows defining which IP / ranges to trust extracting the client IP address from X-Forwarded-For and X-Real-IP headers. We don't know if the proxy chain will give us the proper client address (REMOTE_ADDR in the WSGI environment), so we rely on reading the headers of the proxy before SearXNG (if there is one, in that case it must be added to trusted_proxies) hoping it has done the proper checks. In case a proxy in the chain does not check the client address correctly, integrity is compromised and this should be fixed by whoever manages the proxy, not us.

2025-01-28[refactor] typification of SearXNG (initial) / result items (part 1)Markus Heiser
Typification of SearXNG ======================= This patch introduces the typing of the results. The why and how is described in the documentation, please generate the documentation .. $ make docs.clean docs.live and read the following articles in the "Developer documentation": - result types --> http://0.0.0.0:8000/dev/result_types/index.html The result types are available from the `searx.result_types` module. The following have been implemented so far: - base result type: `searx.result_type.Result` --> http://0.0.0.0:8000/dev/result_types/base_result.html - answer results --> http://0.0.0.0:8000/dev/result_types/answer.html including the type for translations (inspired by #3925). For all other types (which still need to be set up in subsequent PRs), template documentation has been created for the transition period. Doc of the fields used in Templates =================================== The template documentation is the basis for the typing and is the first complete documentation of the results (needed for engine development). It is the "working paper" (the plan) with which further typifications can be implemented in subsequent PRs. - https://github.com/searxng/searxng/issues/357 Answer Templates ================ With the new (sub) types for `Answer`, the templates for the answers have also been revised, `Translation` are now displayed with collapsible entries (inspired by #3925). !en-de dog Plugins & Answerer ================== The implementation for `Plugin` and `Answer` has been revised, see documentation: - Plugin: http://0.0.0.0:8000/dev/plugins/index.html - Answerer: http://0.0.0.0:8000/dev/answerers/index.html With `AnswerStorage` and `AnswerStorage` to manage those items (in follow up PRs, `ArticleStorage`, `InfoStorage` and .. will be implemented) Autocomplete ============ The autocompletion had a bug where the results from `Answer` had not been shown in the past. To test activate autocompletion and try search terms for which we have answerers - statistics: type `min 1 2 3` .. in the completion list you should find an entry like `[de] min(1, 2, 3) = 1` - random: type `random uuid` .. in the completion list, the first item is a random UUID Extended Types ============== SearXNG extends e.g. the request and response types of flask and httpx, a module has been set up for type extensions: - Extended Types --> http://0.0.0.0:8000/dev/extended_types.html Unit-Tests ========== The unit tests have been completely revised. In the previous implementation, the runtime (the global variables such as `searx.settings`) was not initialized before each test, so the runtime environment with which a test ran was always determined by the tests that ran before it. This was also the reason why we sometimes had to observe non-deterministic errors in the tests in the past: - https://github.com/searxng/searxng/issues/2988 is one example for the Runtime issues, with non-deterministic behavior .. - https://github.com/searxng/searxng/pull/3650 - https://github.com/searxng/searxng/pull/3654 - https://github.com/searxng/searxng/pull/3642#issuecomment-2226884469 - https://github.com/searxng/searxng/pull/3746#issuecomment-2300965005 Why msgspec.Struct ================== We have already discussed typing based on e.g. `TypeDict` or `dataclass` in the past: - https://github.com/searxng/searxng/pull/1562/files - https://gist.github.com/dalf/972eb05e7a9bee161487132a7de244d2 - https://github.com/searxng/searxng/pull/1412/files - https://github.com/searxng/searxng/pull/1356 In my opinion, TypeDict is unsuitable because the objects are still dictionaries and not instances of classes / the `dataclass` are classes but ... The `msgspec.Struct` combine the advantages of typing, runtime behaviour and also offer the option of (fast) serializing (incl. type check) the objects. Currently not possible but conceivable with `msgspec`: Outsourcing the engines into separate processes, what possibilities this opens up in the future is left to the imagination! Internally, we have already defined that it is desirable to decouple the development of the engines from the development of the SearXNG core / The serialization of the `Result` objects is a prerequisite for this. HINT: The threads listed above were the template for this PR, even though the implementation here is based on msgspec. They should also be an inspiration for the following PRs of typification, as the models and implementations can provide a good direction. Why just one commit? ==================== I tried to create several (thematically separated) commits, but gave up at some point ... there are too many things to tackle at once / The comprehensibility of the commits would not be improved by a thematic separation. On the contrary, we would have to make multiple changes at the same places and the goal of a change would be vaguely recognizable in the fog of the commits.

2024-03-11[mod] pylint all files with one profile / drop PYLINT_SEARXNG_DISABLE_OPTIONMarkus Heiser
In the past, some files were tested with the standard profile, others with a profile in which most of the messages were switched off ... some files were not checked at all. - ``PYLINT_SEARXNG_DISABLE_OPTION`` has been abolished - the distinction ``# lint: pylint`` is no longer necessary - the pylint tasks have been reduced from three to two 1. ./searx/engines -> lint engines with additional builtins 2. ./searx ./searxng_extra ./tests -> lint all other python files Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>
2023-11-01[mod] isolation of botdetection from the limiterMarkus Heiser
This patch was inspired by the discussion around PR-2882 [2]. The goals of this patch are: 1. Convert plugin searx.plugin.limiter to normal code [1] 2. isolation of botdetection from the limiter [2] 3. searx/{tools => botdetection}/config.py and drop searx.tools 4. in URL /config, 'limiter.enabled' is true only if the limiter is really enabled (Redis is available). This patch moves all the code that belongs to botdetection into namespace searx.botdetection and code that belongs to limiter is placed in namespace searx.limiter. Tthe limiter used to be a plugin at some point botdetection was added, it was not a plugin. The modularization of these two components was long overdue. With the clear modularization, the documentation could then also be organized according to the architecture.

2023-06-01[mod] botdetection - improve ip_limit and link_token methodsMarkus Heiser
- counting requests in LONG_WINDOW and BURST_WINDOW is not needed when the request is validated by the link_token method [1] - renew a ping-key on validation [2], this is needed for infinite scrolling, where no new token (CSS) is loaded. / this does not fix the BURST_MAX issue in the vanilla limiter - normalize the counter names of the ip_limit method to 'ip_limit.*' - just integrate the ip_limit method straight forward in the limiter plugin / non intermediate code --> ip_limit now returns None or a werkzeug.Response object that can be passed by the plugin to the flask application / non intermediate code that returns a tuple [1] https://github.com/searxng/searxng/pull/2357#issuecomment-1566113277 [2] https://github.com/searxng/searxng/pull/2357#discussion_r1208542206 [3] https://github.com/searxng/searxng/pull/2357#issuecomment-1566125979 Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>

2023-05-29[mod] limiter -> botdetection: modularization and documentationMarkus Heiser
In order to be able to meet the outstanding requirements, the implementation is modularized and supplemented with documentation. This patch does not contain functional change, except it fixes issue #2455 ---- Aktivate limiter in the settings.yml and simulate a bot request by:: curl -H 'Accept-Language: de-DE,en-US;q=0.7,en;q=0.3' \ -H 'Accept: text/html' -H 'User-Agent: xyz' \ -H 'Accept-Encoding: gzip' \ 'http://127.0.0.1:8888/search?q=foo' In the LOG: DEBUG searx.botdetection.link_token : missing ping for this request: ..... Since ``BURST_MAX_SUSPICIOUS = 2`` you can repeat the query above two time before you get a "Too Many Requests" response.
