Something that tripped me up today as I was trying to use sharedData: -- in the parent -- Services.ppmm.sharedData.set("foo", "bar"); Services.ppmm.sharedData.flush(); -- in content -- Services.cpmm.sharedData.has("foo"); // returns false If .has is replaced by .get(), or something else caused it to decode (e.g. iterating over the entries*), then it works. * good old "I added logging to dump all the entries to see if I had a typo somewhere and then it worked"
Comment on attachment 8995313 [details] Bug 1478787: Rebuild stale SharedMap on Has() call. https://reviewboard.mozilla.org/r/259776/#review266818 The fix looks fine, but please tests for `has`. Also can you double check we're testing the full [interface](https://searchfox.org/mozilla-central/rev/d47c829065767b6f36d29303d650bffb7c4f94a3/dom/chrome-webidl/MozSharedMap.webidl#19-54). `get`, `set`, `delete`, and `flush` all seem to be covered in the [unit test](https://searchfox.org/mozilla-central/rev/d47c829065767b6f36d29303d650bffb7c4f94a3/dom/ipc/tests/test_sharedMap.js). I *think* [enumeration is covered](https://searchfox.org/mozilla-central/rev/d47c829065767b6f36d29303d650bffb7c4f94a3/dom/ipc/tests/test_sharedMap.js#29-37) but it would be good to double check.

Do we actually need the has method? I'm struggling to think of a case where you'd want to test if a key exists and then not get it.

Do we actually need the has method?

Probably not, but regular Map has one, so.
