BruebachL f4b4365464 [Search] Stop allocating per card in card-name completion (#7604) ... * [Search] Stop allocating per card in card-name completion CardSearchModel::updateSearchResults() runs on every textEdited() signal, walks the whole card database and runs Levenshtein against every matching name. Three costs dominated that path: 1. Every candidate built a QStringList of its searchable names, then lowercased each name into another QString, only to break out of the loop after the first hit. 2. The sort comparator called sortableName() for each comparison, which re-fetched the name (QMap lookup plus QString construction) O(n log n) times. 3. levenshteinDistance() allocated a full len1 x len2 vector of vectors. The search model now lowercases the one name it tests directly, stores the tie-breaking name length once per result, and the comparator only compares integers. levenshteinDistance() uses the standard two-row formulation: same result, O(len2) memory instead of O(len1*len2), with early exits for empty and equal strings. FilterString query closures get the same treatment: - Set queries iterate the set map directly instead of materializing keys()/values() lists for every card. - Rarity queries iterate printings in place instead of copying them into a QList<PrintingInfo> first. - Power/toughness split the string with indexOf and compare QStringViews instead of allocating a QStringList. - Field queries do one hash lookup instead of contains() followed by value(). - Color queries bind the colors string by reference instead of copying. Verified with filter_string_test (42 tests) and a full client build. * [Search] Address review comments - Use std::any_of/std::none_of over the set map's key/value iterators instead of hand-rolled loops. - Extract the name matching into matchingLowercaseName() returning std::optional<QString>. - Reuse the matched name's length for the distance tie-break instead of looking the name up again, removing one getLocalizedName() call per card. - Take the color strings by value; the getters already return by value. --------- Co-authored-by: Lukas Brübach <Bruebach.Lukas@bdosecurity.de>		2026-10-23 11:23:04 +02:00
