Function needsSlashNormalization

pj_datastore/src/plugin_data_host.cpp:57–59

Collapse runs of '/' into a single '/' in a topic/field name. Plugin-supplied names are opaque, but an empty '/'-segment ("//") carries no meaning in the curve hierarchy, so we normalize it here — the one boundary every DataSource/Parser name crosses to become a datastore key — so the stored key, the UI catalog (which reads the descriptor name) and the by-name transform resolver all agree on a sin

// the descriptor name) and the by-name transform resolver all agree on a single slash.
// Common case (no "//") allocates nothing: callers guard on `needsSlashNormalization`.
[[nodiscard]] bool needsSlashNormalization(std::string_view name) {
  return name.find("//") != std::string_view::npos;
}

// A field also needs work if it starts with '/' (a leading slash would double up at
// the "topic/field" junction), not just when it has internal "//".
