2024-07-13[mod] remove py 3.6 leftoversAllen
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>
2023-08-27[mod] searx.network: memory optimizationAlexandre Flament
Avoid to create a SSLContext in AsyncHTTPTransportNoHttp See: * https://github.com/encode/httpx/blob/0f61aa58d66680c239ce43c8cdd453e7dc532bfc/httpx/_transports/default.py#L271 * https://github.com/encode/httpx/issues/2298
2023-08-21Bump httpx 0.21.2 from to 0.24.1Alexandre Flament
2023-03-19[mod] Shuffle httpx's default ciphers of a SSL context randomly.Markus Heiser
From the analyse of @9Ninety [1] we know that DDG (and may be other engines / I have startpage in mind) does some kind of TLS fingerprint to block bots. This patch shuffles the default ciphers from httpx to avoid a cipher profile that is known to httpx (and blocked by DDG). [1] https://github.com/searxng/searxng/issues/2246#issuecomment-1467895556 ---- From `What Is TLS Fingerprint and How to Bypass It`_ > When implementing TLS fingerprinting, servers can't operate based on a > locked-in whitelist database of fingerprints. New fingerprints appear > when web clients or TLS libraries release new versions. So, they have to > live off a blocklist database instead. > ... > It's safe to leave the first three as is but shuffle the remaining ciphers > and you can bypass the TLS fingerprint check. .. _What Is TLS Fingerprint and How to Bypass It: https://www.zenrows.com/blog/what-is-tls-fingerprint#how-to-bypass-tls-fingerprinting Signed-off-by: Markus Heiser <markus.heiser@darmarit.de> Closes: https://github.com/searxng/searxng/issues/2246
2022-10-14searx.network: add "verify" option to the networksAlexandre Flament
Each network can define a verify option: * false to disable certificate verification * a path to existing certificate. SearXNG uses SSL_CERT_FILE and SSL_CERT_DIR when they are defined see https://www.python-httpx.org/environment_variables/#ssl_cert_file

2022-01-05[mod] upgrade httpx 0.21.2Alexandre Flament
httpx 0.21.2 and httpcore 0.14.4 fix multiple issues: * https://github.com/encode/httpx/releases/tag/0.21.2 * https://github.com/encode/httpcore/releases/tag/0.14.4 so most of the workarounds in searx.network have been removed.

2021-09-17[pylint] fix global-variable-not-assigned issuesMarkus Heiser
If there is no write access, there is no need for global. Remove global statement if there is no assignment. global-variable-not-assigned: Using global for names but no assignment is done Used when a variable is defined through the "global" statement but no assignment to this variable is done. In Pylint 2.11 the global-variable-not-assigned checker now catches global variables that are never reassigned in a local scope and catches (reassigned) functions [1][2] [1] https://pylint.pycqa.org/en/latest/whatsnew/2.11.html [2] https://github.com/PyCQA/pylint/issues/1375 Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>
2021-09-17[mod] searx.network: remove redundant codeAlexandre Flament
searx.client.new_client: the proxies parameter is a dictonnary, and the protocol (key of the dictionnary) is already normalized (see usage of searx.network.network.PROXY_PATTERN_MAPPING)

adjust searx.network module to the new internal API see https://github.com/encode/httpx/pull/1522

2021-05-05[mod] searx.network.client: the same configuration reuses the same ↵Alexandre Flament
ssl.SSLContext before there was one ssl.SSLContext per client. see https://github.com/encode/httpx/issues/978
2021-04-27[fix] searx.network: fix rare cases where LOOP is NoneAlexandre Flament
* searx.network.client.LOOP is initialized in a thread * searx.network.__init__ imports LOOP which may happen before the thread has initialized LOOP This commit adds a new function "searx.network.client.get_loop()" to fix this issue
2021-04-12[httpx] replace searx.poolrequests by searx.networkAlexandre Flament
settings.yml: * outgoing.networks: * can contains network definition * propertiers: enable_http, verify, http2, max_connections, max_keepalive_connections, keepalive_expiry, local_addresses, support_ipv4, support_ipv6, proxies, max_redirects, retries * retries: 0 by default, number of times searx retries to send the HTTP request (using different IP & proxy each time) * local_addresses can be "192.168.0.1/24" (it supports IPv6) * support_ipv4 & support_ipv6: both True by default see https://github.com/searx/searx/pull/1034 * each engine can define a "network" section: * either a full network description * either reference an existing network * all HTTP requests of engine use the same HTTP configuration (it was not the case before, see proxy configuration in master)
