A race condition exists where after adding an unapproved transaction,
it could be mutated and then replaced when the default gas parameters
are set. This happens because the transaction is added to state and
broadcast before the default gas parameters are set, because
calculating the default gas parameters to use takes some time.
Once they've been calculated, the false assumption was made that the
transaction hadn't changed.
The method responsible for setting the default gas now retrieves an
up-to-date copy of `txMeta`, and conditionally sets the defaults only
if they haven't yet been set.
This race condition was introduced in #2962, though that PR also added
a loading screen that avoided this issue by preventing the user from
interacting with the transaction until after the gas had been
estimated. Unfortunately this loading screen was not carried forward to
the new UI.
* Remove `estimatedGas` property from `txMeta`
The `estimatedGas` property was a cache of the gas value estimated for
a transaction when the default gas limit was set. This property wasn't
used anywhere. It may have been useful for debugging purposes, but the
same gas estimate is already stored on the `history` property so it
should be present in state logs regardless.
* Remove `gasLimitSpecified` txMeta property
The `gasLimitSpecified` property of `txMeta` wasn't used for anything.
It might have been useful for debugging purposes, but whether or not
the gas limit was specified can also be determined from looking at the
transaction history, so it's not a huge loss.
* Remove `gasPriceSpecified` txMeta property
The `gasPriceSpecified` property of `txMeta` wasn't used for anything.
It might have been useful for debugging purposes, but whether or not
the gas price was specified can also be determined from looking at the
transaction history, so it's not a huge loss.
* Remove `simpleSend` txMeta property
The `simpleSend` property of `txMeta` was used to ensure a buffer was
not added to the gas limit during gas estimation for simple send
transactions. It was made redundant by #8484, which accomplishes this
without the use of this property.
`analyzeGasUsage` now returns the results of the analysis rather than
setting them directly on `txMeta`. The caller is now responsible for
mutating `txMeta` instead. Functionally this should be identical to
before.
The simple send gas estimation has been moved out of the gas estimation
module, and into the transaction controller. This was done in an effort
to limit the number of places where `txMeta` is mutated while the
default gas parameters are being set.
* Specify type before parameter name
Various JSDoc `@param` entries were specified as `name {type}` rather
than `{type} name`.
A couple of `@return` entries have been given types as well.
* Use JSDoc optional syntax rather than Closure syntax
* Use @returns rather than @return
* Use consistent built-in type capitalization
Primitive types are lower-case, and Object is upper-case.
* Separate param/return description with a dash
* Set a default value for code in _determineTransactionCategory
* Adds e2e tests that fail when token txs without gas param are not properly handled.
* Adds unit tests for _determineTransactionCategory
* Base error throwing and simple gas setting in estimateTxGas on transactionCategory
* Adds a transactionCategory to txMeta for use in UI
* Update transaction controller and tx-gas-util documentation on new code param in multiple functions.
