@Ericson2314:matrix.orgJohn Ericson fzakaria: https://github.com/NixOS/nix/pull/14023/files OK here is WIP thing 16:14:15
@Ericson2314:matrix.orgJohn Ericson Sergei Zimmerman (xokdvium): ^ this has one of the worst C++ errors I've every seen! 16:14:29
@Ericson2314:matrix.orgJohn EricsonI think my wrapper constructor for the std::variant class is shadowing a built-in constructor16:14:51
@Ericson2314:matrix.orgJohn Ericsonbut also the template instation trace in the diagnostic is missing16:15:11
@fzakaria:one.ems.hostfzakariawhy does it need whoelStoreView16:15:25
@Ericson2314:matrix.orgJohn Ericsonso I can't tell how things are being invoked / ultimately from what16:15:27
@Ericson2314:matrix.orgJohn Ericson for get getFSAccessor method 16:15:40
@Ericson2314:matrix.orgJohn Ericsonmaybe that should be changed so you can only ask the store for individual object source accessors16:15:55
@Ericson2314:matrix.orgJohn Ericsonbut that is a separate refactor16:15:59
@Ericson2314:matrix.orgJohn Ericsonand that also may not work16:16:03
@fzakaria:one.ems.hostfzakariaoh you merge it16:16:15
@fzakaria:one.ems.hostfzakariaon every call to addtoStore16:16:32
@Ericson2314:matrix.orgJohn Ericson yeah I am using shared pointers, but conceptually the std::map<StorePath, ....> owns the data 16:16:39
