+++ This bug was initially created as a clone of Bug #981921 +++

Once bug 981921 has been fixed, we can update tps to retrieve the real keys from the server. Right now those have been hard-coded:
Wrong dependency order. I will work on this bug once bug 966434 has been finished the refactoring.

Summary: Update TPS to retrieve keys from server instead of hard-codind them → Update TPS to retrieve keys from server instead of hard-coding them
Chris, I have a problem here and I don't know how to continue. So I added the code to retrieve the keys. That works fine and I get keyA and wrapKB. I can decode keyA and use it but I fail for wrapKB. Reason is that I need getUserAccountData().unwrapBKey. I'm not sure where to get it from. There is the fxAccounts instance but I cannot access the getUserAccountData() method because it is undefined.

So what shall I do in the following file:

What I have right now:

    client.signIn(email, password, true).then(credentials => {
      // Retrieve keys for the signed in account
      client.accountKeys(credentials.keyFetchToken).then((bundle) => {
??? ==> let data = yield fxAccounts.internal.getUserAccountData();
        let kB_hex = CryptoUtils.xor(CommonUtils.hexToBytes(data.unwrapBKey),

        credentials.kA = CommonUtils.bytesAsHex(bundle.kA);
        credentials.kB = CommonUtils.bytesAsHex(kB_hex);

The code in question I got from an existing unit test, but I cannot access fxAccounts.internal here.

Looks great! r+ with that one little docs change.

while we're at it, let's change this to say "a keyFetchToken which has not yet been used", to avoid implying that this function doesn't use the token. (keyFetchTokens are single-use).

Updated patch for the jsdoc comment. For safety I pushed it to try. Will land it later when all is green.

If all sticks I will request backports. I think it would be good to even have this patch landed on beta. Brian what do you think?

Eh, if you need it for testing beta, sure, but I don't think anything needs it.

Edwin, what would be your testing strategy in terms of TPS for beta? Do you want to see CI runs for that branch? If yes, we would have to backport this patch to beta.

Re: comment #12 - getting TPS running on beta is low priority at this time.  The highest priority is getting TPS running with all tests passing as we want any regressions to be fixed prior to fx29 release. So we don't need CI to run on Beta for the Fx29 release.

Thanks Edwin. I will keep the firefox-29 affected flag, so we can query for non-backported patches later. I will continue with my work on m-c and m-a.
