// This file defines static prefs, i.e. those that are defined at startup and
|
|
// used entirely or mostly from C++ code.
|
|
//
|
|
// If a pref is listed here and also in a prefs data file such as all.js, the
|
|
// value from the latter will override the value given here. For vanilla
|
|
// browser builds such overrides are discouraged, but they are necessary for
|
|
// some configurations (e.g. Thunderbird).
|
|
//
|
|
// The file is separated into sections, where the sections are determined by
|
|
// the first segment of the prefnames within (e.g. "network.predictor.enabled"
|
|
// is within the "Network" section). Sections should be kept in alphabetical
|
|
// order, but prefs within sections need not be.
|
|
//
|
|
// Normal prefs
|
|
// ------------
|
|
// Definitions of normal prefs in this file have the following form.
|
|
//
|
|
// PREF(<pref-name-string>, <cpp-type>, <default-value>)
|
|
//
|
|
// - <pref-name-string> is the name of the pref, as it appears in about:config.
|
|
// It is used in most libpref API functions (from both C++ and JS code).
|
|
//
|
|
// - <cpp-type> is one of bool, int32_t, float, or String (which is just a
|
|
// typedef for `const char*` in StaticPrefs.h). Note that float prefs are
|
|
// stored internally as strings.
|
|
//
|
|
// - <default-value> is the default value. Its type should match <cpp-type>.
|
|
//
|
|
// VarCache prefs
|
|
// --------------
|
|
// A VarCache pref is a special type of pref. It can be accessed via the normal
|
|
// pref hash table lookup functions, but it also has an associated global
|
|
// variable (the VarCache) that mirrors the pref value in the prefs hash table,
|
|
// and a getter function that reads that global variable. Using the getter to
|
|
// read the pref's value has the two following advantages over the normal API
|
|
// functions.
|
|
//
|
|
// - A direct global variable access is faster than a hash table lookup.
|
|
//
|
|
// - A global variable can be accessed off the main thread. If a pref *is*
|
|
// accessed off the main thread, it should use an atomic type. (But note that
|
|
// many VarCaches that should be atomic are not, in particular because
|
|
// Atomic<float> is not available, alas.)
|
|
//
|
|
// Definitions of VarCache prefs in this file has the following form.
|
|
//
|
|
// VARCACHE_PREF(
|
|
// <pref-name-string>,
|
|
// <pref-name-id>,
|
|
// <cpp-type>, <default-value>
|
|
// )
|
|
//
|
|
// - <pref-name-string> is the same as for normal prefs.
|
|
//
|
|
// - <pref-name-id> is the name of the static getter function generated within
|
|
// the StaticPrefs class. For consistency, the identifier for every pref
|
|
// should be created by starting with <pref-name-string> and converting any
|
|
// '.' or '-' chars to '_'. For example, "foo.bar_baz" becomes
|
|
// |foo_bar_baz|. This is arguably ugly, but clear, and you can search for
|
|
// both using the regexp /foo.bar.baz/.
|
|
//
|
|
// - <cpp-type> is one of bool, int32_t, uint32_t, float, or an Atomic version
|
|
// of one of those. The C++ preprocessor doesn't like template syntax in a
|
|
// macro argument, so use the typedefs defines in StaticPrefs.h; for example,
|
|
// use `ReleaseAcquireAtomicBool` instead of `Atomic<bool, ReleaseAcquire>`.
|
|
//
|
|
// - <default-value> is the same as for normal prefs.
|
|
//
|
|
// Note that Rust code must access the global variable directly, rather than via
|
|
// the getter.
