* Each peer has a "sane/insane/unknown" status
* Status updated based on peer ledger sequence
* Status reported in peer json
* Only sane peers preferred for historical ledgers
* Overlay endpoints only accepted from known sane peers
* Untrusted proposals not relayed from insane peers
* Untrusted validations not relayed from insane peers
* Transactions from insane peers are not processed
* Periodically drop outbound connections to bad peers
* Bad peers get bootcache valence of zero
Peer "sanity" is based on the ledger sequence number they are on. We
quickly become able to assess this based on current trusted validations.
We quarrantine rogue messages and disconnect bad outbound connections to
help maintain the configured number of good outbound connections.
In some code paths, we bump the SHAMap sequence number
before we unshare. This forces SHAMapTreeNode to be
copied. By making the ledger immutable we cause the
unsharing to occur earlier, eliminating the copies.
* Performance motivated.
* Several of these called size() which is O(N) in gcc-4.8.
* Remove container copy from LedgerConsensusImp::playbackProposals().
* Addresses RIPD-284.
LedgerMaster::getLedgerBySeq should return a validated
ledger (rather than the the open or closed ledger) for
a sequence number for which it has a fully-validated ledger.
Legacy workarounds for Visual Studio non thread-safe initialization
of function local objects with static storage duration are removed:
* Remove LeakChecked
* Remove StaticObject
* Remove SharedSingleton
In normal operation, InboundLedgers::findCreate never returns null, but
during system shutdown, it will return null.
Since this only happens in system shutdown, when findCreate returns null
the calling function stops what it was doing and returns.
During testing, an issue where destroying the application object
and creating a new one caused problems with a static PathTable. This table
is now cleared when re-initialized.
An alternative to the unity build, the classic build compiles each
translation unit individually. This adds more modules to the classic build:
* Remove unity header app.h
* Add missing includes as needed
* Remove obsolete NodeStore backend code
* Add app/, core/, crypto/, json/, net/, overlay/, peerfinder/ to classic build
This replaces the experimental validators module with foundational
code to implement a new system for tracking validators, validations and
the UNL. The code is turned off by default, in BeastConfig.h
* Remove obsolete public Manager interfaces
* Remove obsolete database methods
* Remove obsolete ChosenList concept
* Remove obsolete code
* Add missing includes
* Tidy up STValidation.h
* Move factory function to Validators::make_Manager
* Add Connection object for tracking STValidations
Makes rippled configurable to support deletion of all data in its key-value
store (nodestore) and ledger and transaction SQLite databases based on
validated ledger sequence numbers. All records from a specified ledger
and forward shall remain available in the key-value store and SQLite, and
all data prior to that specific ledger may be deleted.
Additionally, the administrator may require that an RPC command be
executed to enable deletion. This is to align data deletion with local
policy.
