* accounts/abi: allow overloaded argument names
In solidity it is possible to create the following contract:
```
contract Overloader {
struct F { uint _f; uint __f; uint f; }
function f(F memory f) public {}
}
```
This however resulted in a panic in the abi package.
* accounts/abi fixed error handling
* accounts/abi: added documentation
* accounts/abi: reduced usage of arguments.LengthNonIndexed
* accounts/abi: simplified reflection logic
* accounts/abi: moved testjson data into global declaration
* accounts/abi: removed duplicate test cases
* accounts/abi: reworked abi tests
* accounts/abi: added more tests for abi packing
* accounts/abi/bind: refactored base tests
* accounts/abi: run pack tests as subtests
* accounts/abi: removed duplicate tests
* accounts/abi: removed unnused arguments.LengthNonIndexed
Due to refactors to the code, we do not need the arguments.LengthNonIndexed function anymore.
You can still get the length by calling len(arguments.NonIndexed())
* accounts/abi: added type test
* accounts/abi: modified unpack test to pack test
* accounts/abi: length check on arrayTy
* accounts/abi: test invalid abi

* all: seperate consensus error and evm internal error
There are actually two types of error will be returned when
a tranaction/message call is executed: (a) consensus error
(b) evm internal error. The former should be converted to
a consensus issue, e.g. The sender doesn't enough asset to
purchase the gas it specifies. The latter is allowed since
evm itself is a blackbox and internal error is allowed to happen.
This PR emphasizes the difference by introducing a executionResult
structure. The evm error is embedded inside. So if any error
returned, it indicates consensus issue happens.
And also this PR improve the `EstimateGas` API to return the concrete
revert reason if the transaction always fails

* accounts/abi: refactored methodName and eventName
This commit moves the complicated logic of how we assign method names
and event names if they already exist into their own functions for
better readability.
* accounts/abi: prevent recalculation of internal
In this commit, I changed the way we calculate the string
representations, sig representations and the id's of methods. Before
that these fields would be recalculated everytime someone called .Sig()
.String() or .ID() on a method or an event.
Additionally this commit fixes issue #20856 as we assign names to inputs
with no name (input with name "" becomes "arg0")
* accounts/abi: added unnamed event params test
* accounts/abi: fixed rebasing errors in method sig
* accounts/abi: fixed rebasing errors in method sig
* accounts/abi: addressed comments
* accounts/abi: added FunctionType enumeration
* accounts/abi/bind: added test for unnamed arguments
* accounts/abi: improved readability in NewMethod, nitpicks
* accounts/abi: method/eventName -> overloadedMethodName
* accounts/abi: implement new fackball functions
In Solidity v0.6.0, the original fallback is separated
into two different sub types: fallback and receive.
This PR addes the support for parsing new format abi
and the relevant abigen functionalities.
* accounts/abi: fix unit tests
* accounts/abi: minor fixes
* accounts/abi, mobile: support jave binding
* accounts/abi: address marius's comment
* accounts/abi: Work around the uin64 conversion issue
Co-authored-by: Guillaume Ballet <gballet@gmail.com>
* accounts/abi: fix various issues
The fixed issues include:
(1) If there is no return in a call function, unpack should
return nil error
(2) For some functions which have struct array as parameter,
it will also be detected and generate the struct definition
(3) For event, if it has non-indexed parameter, the parameter
name will also be assigned if empty. Also the internal struct
will be detected and generate struct defition if not exist.
(4) Fix annotation generation in event function
* accounts/abi: add new abi field internalType
* accounts: address comments and add tests
* accounts/abi: replace strings.ReplaceAll with strings.Replace
The abi package already supports function overload by adding a suffix to the overloaded function name, but it uses the function name with suffix to calculate signature(both for the event and method).
This PR fixes it by adding a new field named RawName, which can be used to calcuate all signatures but use Name to distinguish different overloaded function.
* accounts/abi: Fix method overwritten by same name methods.
* accounts/abi: Fix method overwritten by same name methods.

This change inlines the logic of bytesAreProper at its sole
callsite, ABI.Unpack, and applies the multiple-of-32 test only in
the case of unpacking methods. Event data is not required to be a
multiple of 32 bytes long.

Previously it was assumed that wheneven type `[]interface{}` was given
that the interface was empty. The abigen rightfully assumed that
interface slices which already have pre-allocated variable sets to be
assigned.
This PR fixes that by checking that the given `[]interface{}` is larger
than zero and assigns each value using the generic `set` function (this
function has also been moved to abi/reflect.go) and checks whether the
assignment was possible.
The generic assignment function `set` now also deals with pointers
(useful for interface slice mentioned above) by dereferencing the
pointer until it finds a setable type.
Refactored the abi package parsing and type handling. Relying mostly on
package reflect as opposed to most of our own type reflection. Our own
type reflection is still used however for cases such as Bytes and
FixedBytes (abi: bytes•).
This also inclused several fixes for slice handling of arbitrary and
fixed size for all supported types.
This also further removes implicit type casting such as assigning,
for example `[2]T{} = []T{1}` will fail, however `[2]T{} == []T{1, 2}`
(notice assigning *slice* to fixed size *array*). Assigning arrays to
slices will always succeed if they are of the same element type.
Incidentally also fixes#2379
Fixed up `[]byte` slice support such that `function print(bytes input)`
accepts `[]byte` as input and treats it as 1 element rather than a slice
of multiple elements.
Added support for variable length input parameters like `bytes` and
`strings`.
Removed old unmarshalling of return types: `abi.Call(...).([]byte)`.
This is now replaced by a new syntax:
```
var a []byte
err := abi.Call(&a, ...)
```
It also addresses a few issues with Bytes and Strings and can also
handle both fixed and arbitrary sized byte slices, including strings.
