+Subject: [PATCH] Merge commit from fork
+
+* fix(parser): Limit line length in getline
+
+Prevents potential infinite loop and memory exhaustion in
+stream_line_reader::getline by enforcing max line length.
+
+Signed-off-by: Ville Vesilehto <ville@vesilehto.fi>
+
+* fix: increase default max line length to 32k
+
+LONG_QUERY_VALUE test is set at 25k.
+
+Signed-off-by: Ville Vesilehto <ville@vesilehto.fi>
+
+* test(client): expect read error with too long query
+
+Adds a test case (`TooLongQueryValue`) to verify client behavior
+when the request URI is excessively long, exceeding
+`CPPHTTPLIB_MAX_LINE_LENGTH`. In this scenario, the server is
+expected to reset the connection.
