…ons (#174) * Increase `getTransaction` window via ingestion into a local database (#141) * Add common interface between in-memory and on-disk transaction storage * Revert "Add common interface between in-memory and on-disk transaction storage" This reverts commit 3196ade. * Add initial implementation of DB-backed tx store * Drop all references to the in-memory transaction store * Actually filter for the tx hash you want 🤦 * Drop remaining reference to transaction store * Update stellar/go to latest master * Add a bunch of logging/verbose errors, another column to DB * Propogate contexts, fix all bugs; e2e flow works! * Add metric for tx ingestion * Split TransactionHandler into separate readers and writers * Move tx reads into their own isolated, read-only db tx * Add in-memory cache for ledger ranges * Remove cache: read/write are separate so it doesn't work * Add trimming of transactions table based on retention window * Tests work (but dont pass)! Plus some fixes based on test cases 👍 * Tidy up the go.mod file * Fixup the way ledger ranges are handled * Add prometheus metrics back * Drop columns and logging that aren't useful * Incorporate errors into ledger range retrieval * Return instead of log errors in getTransaction * Fixup tests: an empty db isn't a fetch error * Make 24hr the new default transaction retention window, fixup errors * Expect the correct retention window in tests * Use raw byte hash over hex for 1/2 the column space * Rename interfaces to avoid overloading 'Transaction' term * PR feedback: variable rename * Separate tx parsing into its own function * Modify queries to not use transactions * Pass around the logger rather than using the global * Fixup all of the tests to pass a logger * Use subqueries to get around () sqlite limitations * Use .Select() to simplify querying * Add db unit test but it's failing :( * Prefer custom error over EOF or DB nonsense * Prepare randoms in advance, writer for the ledger as well * Pass daemon to db to hook in metrics * Check another error in e2e test * Feedback: use no-op interface, drop metric * Refactor method tests to use 'fake' tx/ledger backend * Simplify code a bit * Fixup mocking interface * Move test function back, fixup metrics and tests * Add `getTransactions` endpoint (#136) * Add cursor for getTransactions * Add validation of pagination and range * implement getTransactions handler - 1 * Add getLedgers * Read a single ledger instead of getting all ledgers * Add ParseCursor method for tx cursor * Cursor changes - 1 * Cursor changes - 2 * Cursor changes - 3 * revert go-mod changes * Use reader.Seek() * Use reader.Seek() - 2 * Add config-options for tx pagination limits * Fix failing cursor test * Go mod changes * Go mod changes - 2 * Add unittests - 1 * Update go.mod and go.sum * Add integration tests * Update go.mod and go.sum * Add ledgerSeq to error string * Add docstrings * Change transactions limits * add defensive check for error other than EOF * add defensive check for error other than EOF - 2 * Change ledger sequence to uint32 * Add comments/docstrings * Include only cursor in response * Use toid instead of new cursor * Revert cursor changes * Return cursor as string in result * Refactor reader.Seek error handling * Small refactoring * Remove startLedger check * Remove endLedger * Import fix * Fix failing tests * Refactor to use new transaction db * Refactor mocks * Refactor unittests for using the new db changes * Refactor integration test * Add config vars for max requests and request duration * Fix failing test * Use transactionInfo struct instead of db.Transactions * Start indexing from 1 instead of 0 for toid * Operation index from 1 * Add lines to make sure structs implement interfaces * Remove omitempty * rename test func * make txInfo struct public and convert string cursor to int * Use sendSuccessfulTransaction helper func * Convert cursor to string in request * Change jrpc response codes * Change ledger close meta code to invalid-params * Revert back to InvalidParams error for reader.Read() * Refactor if-else statement * Refactor if-else statement - 2 * Add documentation on opting into the new db backend (#182) * Refactor getFeeStats changes to add db changes * Remove code making `GetLedgerRange` conform to interface (#186) It's unnecessary because we aren't using that interface anymore. * Add changelog entry for `getTransactions` (#183) * Add more changelog details on new endpoint * Fixup spacing --------- Co-authored-by: George <Shaptic@users.noreply.github.com> Co-authored-by: George Kudrayvtsev <george@stellar.org>
