From d4cdbd6fb6ac3663d069307c4fd0078f4ecf0245 Mon Sep 17 00:00:00 2001 From: John Newbery Date: Fri, 11 Aug 2017 11:25:06 -0400 Subject: [PATCH] [rpc] Deprecate estimatefee RPC Deprecate estimatefee in v0.16, for final removal in v0.17. This commit introduces a phased removal of RPC methods. RPC method is disabled by default in version x, but can be enabled by using the `-deprecatedrpc=` argument. RPC method is removed entirely in version (x+1). --- src/init.cpp | 1 + src/rpc/mining.cpp | 6 ++++++ src/rpc/protocol.h | 1 + src/rpc/server.cpp | 7 +++++++ src/rpc/server.h | 2 ++ test/functional/smartfees.py | 2 +- 6 files changed, 18 insertions(+), 1 deletion(-) diff --git a/src/init.cpp b/src/init.cpp index a997f9740..a1c49a099 100644 --- a/src/init.cpp +++ b/src/init.cpp @@ -430,6 +430,7 @@ std::string HelpMessage(HelpMessageMode mode) strUsage += HelpMessageOpt("-checkmempool=", strprintf("Run checks every transactions (default: %u)", defaultChainParams->DefaultConsistencyChecks())); strUsage += HelpMessageOpt("-checkpoints", strprintf("Disable expensive verification for known chain history (default: %u)", DEFAULT_CHECKPOINTS_ENABLED)); strUsage += HelpMessageOpt("-disablesafemode", strprintf("Disable safemode, override a real safe mode event (default: %u)", DEFAULT_DISABLE_SAFEMODE)); + strUsage += HelpMessageOpt("-deprecatedrpc=", "Allows deprecated RPC method(s) to be used"); strUsage += HelpMessageOpt("-testsafemode", strprintf("Force safe mode (default: %u)", DEFAULT_TESTSAFEMODE)); strUsage += HelpMessageOpt("-dropmessagestest=", "Randomly drop 1 of every network messages"); strUsage += HelpMessageOpt("-fuzzmessagestest=", "Randomly fuzz 1 of every network messages"); diff --git a/src/rpc/mining.cpp b/src/rpc/mining.cpp index f0ffa07e1..5ac32dc97 100644 --- a/src/rpc/mining.cpp +++ b/src/rpc/mining.cpp @@ -789,6 +789,12 @@ UniValue estimatefee(const JSONRPCRequest& request) + HelpExampleCli("estimatefee", "6") ); + if (!IsDeprecatedRPCEnabled("estimatefee")) { + throw JSONRPCError(RPC_METHOD_DEPRECATED, "estimatefee is deprecated and will be fully removed in v0.17.
