1. Add "optional Promise<PaymentDetailsUpdate> detailsPromise" as a parameter
of PaymentRequest.show() in PaymentRequest.webidl.
2. Let PaymentRequest inherit from PromiseNativeHandler, and implement the
ResolvedCallback() and RejectedCallback() to handle the PaymentDetailsUpdate
promise.
3. Update PaymentRequest.show() implementation. If PaymentDetailsUpdate Promise
is not nullptr, the show request would not be transferred to chrome process
immediately until the promise is resolved/rejected.
4. Update selectedShippingOption when requestShipping is true.
5. Change the PaymentMethod id validation sequence according to the spec.
Add a new member mAllowPaymentRequest on nsIDocument and following related
methods,
bool AllowPaymentRequest() const
void SetAllowPaymentRequest(bool aAllowPaymentRequest)
mAllowPaymentRequest is used to check if PaymentRequest is allowed to use on
the document. According to the spec
https://html.spec.whatwg.org/multipage/iframe-embed-object.html#allowed-to-use
the mAllowPaymentRequest should be true under following situations
1. The document is the top level content document.
2. The document is the same origin with its parent document and its parent
document's mAllowPaymentRequest is true.
3. The document is different origin with its parent document but its
parent node is an iframe with allowpaymentrequest flag and the parent
document's mAllowPaymentRquest is true.
This patch also include following mochitests
1. test for allowpaymentrequest flag changing. The flag change effect should
not be applied to the document immediately, it should be updated while
the browsing context is updated.
2. test for effect propagation in the nested iframe.
1. PaymentRequest::PrefEnabled() returns false under non-e10s situation.
2. Add a new mochitest test_block_none10s.html to expect to get ReferenceError
in non-e10s mode.
This patch implements payment method identifier validation algorithm
according to the spec https://w3c.github.io/payment-method-id/.
The steps to validate a payment method identifier with a string pmi are
given by the following algorithm. It returns true if the pmi is valid.
1. Let url be the result of running the basic URL parser with pmi.
2. If url is failure, validate a standardized payment method identifier with
pmi and return the result.
3. Otherwise, validate a URL-based payment method identifier passing url and
return the result.
This patch implements the following changes according to the spec change.
See https://w3c.github.io/payment-request/#constructor step 8 for more
details.
1. Return TypeError during PaymentRequest construction with duplicate
shippingOption id.
2. Set PaymentRequest.shippingOption with the selected shippingOption only
if options.requestShipping is true.
This patch implements currency validation algorithm according to the spec
https://w3c.github.io/payment-request/#validity-checkers.
1. amount.currencySystem must be "urn:iso:std:iso:4217".
2. amount.currency is valid with following criteria
1. The currency length must be 3.
2. The currency contains any character that must be in the range "A" to
"Z"(U+0041 to U+005A) or the range "a" to "z"(U+0061 to U+007A).
According to the spec, converting the currency to upper case and save it in
nsIPaymentRequest.
1. Create a new action response status PAYMENT_NOTSUPPORTED and get rid of
unnecessary method isAccpeted() from nsIPaymentActionResponse.idl.
2. Create canMakePayment() in PaymentRequestService and run it before
launching UI. If canMakePayment() returns false, send PAYMENT_NOTSUPPORTED
back to content process.
3. If chrome process returns PAYMENT_NOTSUPPORTED when calling showPayment(),
throw NotSupportedError DOMException to merchant side.
Getting the top level document's principal when constructing PaymentRequest,
then sending it to chrome process and saving it in nsIPaymentRequest.
Creating a new readonly attribute nsIPrincipal topLevelPrincipal in
nsIPaymentRequest for UI to query the top level document's principal
information.
Per spec, given details and options parameters of PaymentRequest constructor,
1) if details.shippingOptions exists and IDs of all shipping options are unique,
request's shippingOption will be set to the last selected option's ID.
Otherwise, set request's shippingOption to null.
2) if options.requestShipping is ture, set request's shippingType to
options.shippingType. Otherwise, set request's shippingType to null.
