From a385e51a086006c0f7d7c4bc6ed910dbe5375c4d Mon Sep 17 00:00:00 2001 From: pennae Date: Fri, 22 Apr 2022 21:45:39 +0200 Subject: rename SymbolIdx -> Symbol, Symbol -> SymbolStr after #6218 `Symbol` no longer confers a uniqueness invariant on the string it wraps, it is now possible to create multiple symbols that compare equal but whose string contents have different addresses. this guarantee is now only provided by `SymbolIdx`, leaving `Symbol` only as a string wrapper that knows about the intricacies of how symbols need to be formatted for output. this change renames `SymbolIdx` to `Symbol` to restore the previous semantics of `Symbol` to that name. we also keep the wrapper type and rename it to `SymbolStr` instead of returning plain strings from lookups into the symbol table because symbols are formatted for output in many places. theoretically we do not need `SymbolStr`, only a function that formats a string for output as a symbol, but having to wrap every symbol that appears in a message into eg `formatSymbol()` is error-prone and inconvient. --- src/nix/search.cc | 16 +++++++++------- 1 file changed, 9 insertions(+), 7 deletions(-) (limited to 'src/nix/search.cc') diff --git a/src/nix/search.cc b/src/nix/search.cc index 8b1e9ae6c..6febc0a55 100644 --- a/src/nix/search.cc +++ b/src/nix/search.cc @@ -77,13 +77,15 @@ struct CmdSearch : InstallableCommand, MixJSON visit = [&](eval_cache::AttrCursor & cursor, const std::vector & attrPath, bool initialRecurse) { + auto attrPathS = state->symbols.resolve(attrPath); + Activity act(*logger, lvlInfo, actUnknown, - fmt("evaluating '%s'", concatStringsSep(".", attrPath))); + fmt("evaluating '%s'", concatStringsSep(".", attrPathS))); try { auto recurse = [&]() { for (const auto & attr : cursor.getAttrs()) { - auto cursor2 = cursor.getAttr(attr); + auto cursor2 = cursor.getAttr(state->symbols[attr]); auto attrPath2(attrPath); attrPath2.push_back(attr); visit(*cursor2, attrPath2, false); @@ -97,7 +99,7 @@ struct CmdSearch : InstallableCommand, MixJSON auto aDescription = aMeta ? aMeta->maybeGetAttr("description") : nullptr; auto description = aDescription ? aDescription->getString() : ""; std::replace(description.begin(), description.end(), '\n', ' '); - auto attrPath2 = concatStringsSep(".", attrPath); + auto attrPath2 = concatStringsSep(".", attrPathS); std::vector attrPathMatches; std::vector descriptionMatches; @@ -146,21 +148,21 @@ struct CmdSearch : InstallableCommand, MixJSON else if ( attrPath.size() == 0 - || (attrPath[0] == "legacyPackages" && attrPath.size() <= 2) - || (attrPath[0] == "packages" && attrPath.size() <= 2)) + || (attrPathS[0] == "legacyPackages" && attrPath.size() <= 2) + || (attrPathS[0] == "packages" && attrPath.size() <= 2)) recurse(); else if (initialRecurse) recurse(); - else if (attrPath[0] == "legacyPackages" && attrPath.size() > 2) { + else if (attrPathS[0] == "legacyPackages" && attrPath.size() > 2) { auto attr = cursor.maybeGetAttr("recurseForDerivations"); if (attr && attr->getBool()) recurse(); } } catch (EvalError & e) { - if (!(attrPath.size() > 0 && attrPath[0] == "legacyPackages")) + if (!(attrPath.size() > 0 && attrPathS[0] == "legacyPackages")) throw; } }; -- cgit v1.2.3
