This downgrade changes StakePoolTicketFee back to the version which does
not consider DCP-0012 activation.
This resolves an issue where Decrediton sometimes fails to pay VSP fees,
caused by Decrediton and vspd independently calculating the fee amount
using different versions of the algorithm.
Releasing the new algorithm will need to be more carefully coordinated,
potentially requiring both client and server sides to be updated in
sync.
Upgrade the dcrwallet dependency to pick up the new version of
txrules.StakePoolTicketFee which considers the status of DCP0012 in its
fee calculation.
Use dcrd and GCS filters to find voted/revoked tickets rather than using
the dcrwallet TicketInfo RPC.
Using TicketInfo was a bit flakey because wallets do not always
correctly detect votes/revokes, and as a result VSP admins may notice
that with this change vspd detects some historic voted/revoked tickets
which TicketInfo never detected.
* Remove helper func getCommitmentAddress.
This function is only used in one place so removing it does not introduce any duplication. Removing the func also removes the need for errors.Is comparison, which will be very useful in upcoming changes.
* Rename apiError to ErrorCode.
* Don't use inline type for API errors.
* Export webapi errors.
* Export webapi request/responses.
* Add types module for API requests/responses/errors
* ci: Update GitHub actions and linter.
* Update go deps.
* Include commit ID in build info.
Introduced in go 1.18, debug.ReadBuildInfo allows a go process to discover the git commit it was built from.
This allows both tspend and treasury policies to be set by clients on a per-ticket basis. Preferences can be set when initially registering a ticket with `/payfee`, and can be later updated using `/setvotechoices`.
Any requests which alter treasury/tspend policy will be stored in the database using the existing accountability system.
**Note:** This does not include consistency checking, it will need to be added later when dcrwallet has an RPC to retrieve policies in batches.
vspd will now call dcrd RPC `getblockchaininfo` to determine if DCP-0010 is active, and take that information into consideration when calculating ticket registration fee.
This pulls a fix which enables vspd to determine remote client IP using header `X-Forwarded-For` or `X-Real-Ip`.
This depends on the reverse proxy setting those headers appropriately, which can be achieved in nginx 1.20 using the following:
```
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
```
This commit marks the point at which vspd will stop working against dcrd 1.6 and start to target master.
The dcrwallet RPC version has not changed, so vspd continues to work with dcrwallet 1.6 or master.
