*: merging tidb-lightning to release-4.0 (#746) * restore: write index kv pairs and data kv pairs to separate engine (#132) * restore: write index kvs and data kvs to seperate engine * restore: use single engine file to store index * restore: make index engine limited by table concurrency * restore: modify checkpoint proto * restore: implement checkpoint for index engine file * tests: add failpoint for CheckpointStatusIndexImported * Support CSV (#111) * loader: recognize CSV files * *: generalize the parser interface * mydump: added a CSV parser * mydump,restore: enable CSV parser * tests: added integration test for CSV * mydumper: added test case for empty CSV * config: improved description * restore: fixed a compile error on Go 1.12 * update version of tidb to latest release-2.1 (#138) update tidb version to latest release2.1, and add a test case for issue https://github.com/pingcap/tidb/issues/9532 * tidb-lightning-ctl: added --import-engine and --cleanup-engine commands (#125) * *: parameter type fix (#141) * remove changelog and get change logs from release (#146) * test: fix cleanup script to enable re-run integration test locally (#142) Currently, cleanup script in integration test does not work, if the developer wants to re-run integration test in his/her local environment, he/she has to clean /tmp/lightning_test_result manually * restore: fix #140 lightning breaks on tidb-master (#147) * fix deadlock and goroutine leak in chunk restore (#149) * restore: eager release index engine worker after imported (#150) * checkpoint: fix checkpoint not updated in some scenario (#151) Test `checkpoint_error_destroy` in integration got error randomly, both in local environment and JenkinsCI. Lightning could exit before all checkpoints are saved, as the `WaitGroup` is not always added before this line https://github.com/pingcap/tidb-lightning/blob/master/lightning/restore/restore.go#L204 returns 1. After `RestoreController.Run` is returned, no more messages will be sent to `rc.saveCpCh`, so we can close it safely and ensure all `saveCp` are consumed 2. remove some unused code * Revert "fix deadlock and goroutine leak in chunk restore (#149)" (#152) This reverts commit 852c5e954877692035efe5c3e44ddcf8f915d90b. * restore: add local checksum log (#153) * restore: add local checksum log * Update lightning/restore/restore.go Co-Authored-By: lonng * tests: add kill lightning test in checkpoint_chunks case (#158) use gofail to control lightning to kill itself after one chunk is imported * *: parse the data source directly into data and skip the KV encoder (#145) * *: parse the data source directly into data and skip the KV encoder This skips the more complex pingcap/parser, and speeds up parsing speed by 50%. We have also refactored the KV delivery mechanism to use channels directly, and revamped metrics: - Make the metrics about engines into its own `engines` counter. The `tables` counter is exclusively about tables now. - Removed `block_read_seconds`, `block_read_bytes`, `block_encode_seconds` since the concept of "block" no longer applies. Replaced by the equivalents named `row_***`. - Removed `chunk_parser_read_row_seconds` for being overlapping with `row_read_seconds`. - Changed `block_deliver_bytes` into a histogram vec, with kind=index or kind=data. Introduced `block_deliver_kv_pairs`. * tests,restore: prevent spurious error in checkpoint_chunks test Only kill Lightning if the whole chunk is imported exactly. The chunk checkpoint may be recorded before a chunk is fully written, and this will hit the failpoint more than 5 times. * kv: use composed interface to simplify some types * kv: properly handle the SQL mode * common: disable IsContextCanceledError() when log level = debug This helps debugging some mysterious cancellation where the log is inhibited. Added IsReallyContextCanceledError() for code logic affected by error type. * restore: made some log more detailed * restore: made the SlowDownImport failpoint apply to index engines too * restore: do not open a write stream when there are no KV pairs to send * tests: ensure we drop the checkpoints DB before re-run * mydump: fixed various off-by-one errors in the CSV parser * *: rename `!IsContextCanceledError` to `ShouldLogError` * *: addressed comments * restore: zero the checksums and column permutations on initialization * *: addressed comments * tests: add back a missing license header * tests: improve a comment. * tests: fix a test failure due to conflict between #145 and #158 (#159) * tests: fix a test failure due to conflict between #145 and #158 * restore: apply the row count limit to failpoint KillIfImportedChunk too * restore: give priority to small tables for importing (#156) Put the large table in the front of the slice which can avoid large table take a long time to import and block small table to release index worker. * config: Allow overriding some config from command line (#157) * config: remove deprecated -compact, -switch-mode flags from tidb-lightning They can still be called from tidb-lightning-ctl. * config: search also conf/tidb-lightning.toml for default -config path Fallback to standard default if -config is not supplied * config: provide command line arguments for some common options * config: stop searching for tidb-lightning.toml if --config is unspecified * go.mod: upgrade dependencies, esp TiDB -> v3.0.0-beta.1 (#160) * Fix interpretation of integers in a BIT column (#161) * tests: fix existing test failure * mydump: fixed conversion of integers into bits We need to create a special branch for integers, since casting 123 and '123' into BIT type behave differently. Also fixed handling of 0x/0b bit strings since Ragel doesn't recognize '+' in a regex -_-. * mydump: store description of `token` in an array instead of switch cases * tests: test behavior of integers for ENUM and SET types as well * *: replace gofail with new failpoint implementation (#165) * *: use pingcap/log (zap) for logging (#162) * *: use pingcap/log (zap) for logging Some redundant logs (e.g. logging about the same thing inside and outside a function) are removed. The {QueryRow,Transact,Exec}WithRetry functions are revamped to include the logger. * common,config: addressed comments * *: addressed comments * restore,verification: addressed comments * main: sync log before exit + update failpoint dep (#168) * kv: fix handling of column default values (#170) * kv: fix handling of column default values * if the column is AUTO_INCREMENT, fill in with row_id (assume it is missing for the entire table instead of just a few values) * if the column has DEFAULT, fill in that value * tests: ensure DEFAULT CURRENT_TIMESTAMP works * tests,restore: re-enable the exotic_filenames test (#172) * config: reduce default table-concurrency from 8 to 6 (#175) Ensures table + index <= the default max-open-engine which is 8. * Support table routing rules (merging sharded tables) (#95) * config: added [[routes]] config * mydump, restore: support table routing * tests: added test case for table routing * mydump: ensure rerouted schemas will not be created * config: allows routes to be case-sensitive * restore: replace CREATE TABLE -> IF NOT EXISTS using tidb/parser * mydump/loader_test: add unit test for route() and refactor * tests: TiDB doesn't support `DECIMAL(20, 0)`. * tests: workaround pingcap/parser#310 * tests: removes the emoji from a test database name (#179) The character is too exotic and breaks TiDB and some old git. * *: fix failpoint-ctl path, unify failpoint runtime and ctl to same version (#180) * restore: fix the potential null pointer exception when logging progress (#178) If no files are completely imported within the first 5 minutes, we get `finished == 0` and the logger will try to log a nil field and crashes. * kv,restore: log which value caused conversion failure (#154) * kv,restore: log row content and column info on failure * restore: log a warning if a column is missing * restore: retry if deliver KVs to importer (#176) * config: automatically discover tidb.pd-addr and tidb.port if not provided (#173) * config: automatically discover tidb.pd-addr and tidb.port if not provided * config: error if port/pd-addr is still wrong after adjust * config: use tidb/config.Config instead of a custom struct * config: remove recognition of AdvertiseAddress TiDB team says it is useless and TiDB won't work with port-forwarding. * *: added linters (#183) * Makefile: added `make check` to perform static linting Moved the failpoint tool into `tools/bin` for consistency. Renamed the phony targets `failpoint-{enable,disable}` to `failpoint_{enable,disable}` for consistency. Renamed the `install-failpoint` target to the real path name. * *: fix gofmt suggestions * go.mod,Makefile: unify the two failpoint versions Added a script to ensure they never differ. * Makefile: fixed the scope of golangci-lint * common: improve unit test coverage of 'common' package (#186) * common: improve unit test coverage of 'kv' package (#187) * Make the parsers stricter, and improve unit test coverage of `mydump` package (#185) * lightning: improve unit test coverage of 'lightning' package (#188) * README: update coverage status badge (#189) * config: improve unit test coverage of 'config' package (#192) Signed-off-by: Lonng * Add unit tests for kv/importer and restore/checkpoints, plus some bug fixes (#191) * kv: add unit test for importer (based on a mocked gRPC client) * restore: remove the unnecessary SHOW CREATE TABLE calls We can now reconstruct the table info directly from the HTTP reply, so the SHOW CREATE TABLE results are now useless. Better drop them. * restore: add unit test for tidb.go * common: ensure sqlmock errors are not retryable * restore: fix error where checkpoint status of index engine is not updated Also, made the WholeTableEngineID constant public. * restore: rename a confusing variable * restore: fix bug where --checkpoint-error-destroy=all skips index engine * restore: prevent NPE when getting missing table from file checkpoint * restore: add unit tests for checkpoints * kv: address importer comments * kv: also exposes the mock Importer constructor to other tests * Add unit tests for 'restore.go' (TableRestore and chunkRestore) (#193) * go.mod: update dependencies (#197) * config,lightning: Implements server mode (#198) * test: speed up TestGetJSON Force a shorter timeout on the HTTP client, so that accessing `http://not-exists` won't take 30 seconds. * config,lightning: implement "server mode" In "Server Mode" Lightning will wait for tasks submitted via the HTTP API `POST /tasks`, and will keep running until Ctrl+C. Multiple tasks are executed sequentially. The config is split into "Global config" and "Task config", which shares the same structure for compatibility and simplicity. The pprof-port setting has been deprecated in favor of status-addr, for compatibility with other tools. * lightning,config: cover some of the new code * lightning: added `GET /tasks` API to get number of queued tasks * *: addressed comments * config,lightning: use a linked hash map to store queued configs Changed /task to return JSON. This is to prepare for an API removing a queued task, and also to remove the artificial task queue size limit. * config: change TaskID to record the current timestamp * go.mod: update dependencies (#200) * Post restore config fix (#202) * fix the mistake in lightning config file * fix typo * remote the "also" in description * Introduce a basic web interface (#199) * restore,checkpoints: move checkpoints into its own package This allows both the "restore" package to import the "web" package, and allow the "web" package to use "checkpoints", without leading to circular dependency. * verification: implemented json.Marshaler for KVChecksum * *: expose the current import progress to HTTP interface * common: added "Pauser" synchronization primitive * lightning: allows status address to reliably use port 0 for testing * config: ensure AllIDs() return a deterministic order * lightning,restore: support pausing, moving and deleting tasks through HTTP Also fixed some goroutine leaks and crashes after canceling. * common: fixed the bug where checksum is not cancelable * config: added configlist.{MoveToFront, MoveToBack} * web,lightning: added a web interface * web: explain the web interface * web: added OpenAPI (Swagger) spec of the HTTP API * common: avoid double-close a channel The channel may be double-closed given this sequence: 0. [B] p.Pause() 1. [A] p.Wait(ctx), run until the select 2. [B] p.Resume(), run until the for loop 3. [C] cancel the ctx 4. [A] continue from select, and close the channel 5. [B] continue the for loop, using the old copy of waiters, it will close the channel again, causing double-close error. We just avoid closing the waiter when ctx expired. * common: added a test to check for contended pause/resume flip * common: fixed a potential race condition * verification: change JSON field of checksum from cksum to checksum * web: document the OpenAPI def and why we don't support webpack-dev-server Fixed a potential typing error (see TypeStrong/atom-typescript#1053). * config: prevents task ID conflict which may happen with a coarse clock * restore: prevent encodeLoop panicking if deliverResult is closed? * checkpoints,lightning: address comments * Update README.md (#207) * Improve errors and logs on syntax error / conversion failure (#201) * mydump: ensure syntax error won't log more than 256 bytes of content * kv: log only the affected column on cast failure Also annotate the returned error by the failed value * restore: annotate encode failure with the current file being processed * checkpoints: reduce log level of missing checkpoint file from warn to info * tests,web: exclude these directories from the Go module (#209) * lightning/restore: fix ColumnPermutation calculation (#210) Signed-off-by: Lonng * build(deps): bump lodash from 4.17.11 to 4.17.14 in /web (#213) * build(deps): bump lodash from 4.17.11 to 4.17.14 in /web Bumps [lodash](https://github.com/lodash/lodash) from 4.17.11 to 4.17.14. - [Release notes](https://github.com/lodash/lodash/releases) - [Commits](https://github.com/lodash/lodash/compare/4.17.11...4.17.14) Signed-off-by: dependabot[bot] Co-authored-by: dependabot[bot] * web: execute `npm audit fix` * web: update corresponding Go code * *: adjust solution for TOOL-1420 and add a test case (#214) Move the ToLower operation from (*TableRestore).initializeColumns() to (*ChunkParser).ReadRow(). In fact this is the same as the CSV parser. * tests: add test case for simple partitioned tables (#206) * checkpoints: remove node_id field and rename the schema on keep-after-success (#208) * lightning: reduce the chance of spurious error in web server * checkpoints: remove node_id We intend to separate checkpoints from multiple nodes into different schemas instead. Since one node now owns the entire schema, when removing all checkpoints we just drop the entire schema. We also changed the file driver to delete the file instead of just emptying the content. * lightning: set the task ID even outside server mode * checkpoints,restore: move the checkpoints database on keep-after-success The schema is renamed as `*.{taskID}.bak`. * checkpoints: addressed comments * config: attempt to solve TOOL-1405 and modify old test cases (#217) * remove outdated target of Makefile * check unused toml keys * remove outdated toml config keys that block * config: improve readablity from review suggestions * config: improve readability * Update lightning/config/config.go Co-Authored-By: kennytm * restore: fix gc life time not recovered after table restore (#218) * restore: fix gc life time not recovered after table restore * empty commit to refresh cla * address comment * address comment * address comment * fix ci * *: abstract the Importer communication into an interface (#215) * common: allow retry on ErrWriteConflictInTiDB (mysql error 8005) * *: perform SwitchMode and Compact directly through ImportSSTService This allows us to perform these actions without relying on Importer. * *: abstracted *kv.Importer into kv.Backend * common,kv: fix comments * kv,restore: addressed comments * restore: fix comments * restore: update and restore GCLifeTime once when parallel (#220) * restore: update and restore GCLifeTime once when parallel * Update lightning/restore/restore.go Co-Authored-By: amyangfei * Update lightning/restore/restore.go Co-Authored-By: amyangfei * Update lightning/restore/restore.go Co-Authored-By: amyangfei * restore: fix bug in reviewing * restore: call ObtainGCLifeTime closer to use * restore: improve readabiilty * restore: reduce struct copy and pointer deref * restore: fix bug in reviewing * Update lightning/restore/restore.go Co-Authored-By: kennytm * restore: improve readability * restore: refine mock expectation order * restore: adjust detail * *: support MySQL backend (#221) * *: support MySQL backend * config: use a constant for backend and checkpoint.driver * kv: address comments * backend: rename `kv` package to `backend` package * config: always skip the system databases (#225) * backend: update mysql backend to tidb backend (#228) * update mysql backend to tidb backend * fix test * lightning/common: add unit test (#229) * add unit test * add unit test * Update lightning/common/util_test.go Co-Authored-By: kennytm * Update lightning/common/util_test.go Co-Authored-By: kennytm * mock: update rpc endpoint (#226) * cmd: do not exit(1) if failed to sync log (#230) * mock: update rpc endpoint (#234) * backend: dynamically calculate the maximum auto-inc ID (#227) This makes sure the final AUTO_INCREMENT value is exactly the maximum value of the auto-inc column.

As explained in #111, the parser was using Ragel to reuse existing framework for simplicity. However as more and more customers start to use Lightning with CSV input, this is the time we need to optimize the things. The new parser was inspired by encoding/csv but almost nothing remained except the recordBuffer/fieldIndexes members to reduce the amount of allocations. We cannot reuse encoding/csv because: encoding/csv does not allow us to track the current read position encoding/csv does not recognize backslash-escaped fields (required for MySQL-generated CSV) encoding/csv does not support disabling quoting Implementing these make the new parser still worse than encoding/csv, but much better than the original one. Parser TPC-C "CUSTOMER" Row encoding/csv 1898 ns/op Original parser 6930 ns/op New parser 2426 ns/op So the new parser is 35% of the original parser and encoding/csv is 80% of the new parser. We can investigate how to squeeze out the remaining 20% later. * backend: fix issue 282 (#283) * backend: fix all wrong escape of '\Z' as '\x26' (which is '&') * tests: try to workaround spurious failure of check_requirements * tests: make the lightning exit detection more precise * tests: fix test * optimize the performance of lightning (#281) * lightning: split large csv file if possible * gofmt * gofmt * unit test * add unit test * tiny change * tiny refine * fix ci * remove useless code * fix ci * fix ci * address comments * go fmt for all * Replace CSV Ragel parser by a hand-written parser copied from encoding/csv Conflicts: lightning/mydump/csv_parser_generated.go * fix conflict * update * update again * send a batch of kv in encodeLoop * use sync.Pool * Close channel instead of push one entry. * Use copy instead append * Fix test and failpoint version * Reuse slice of record This expected to avoid about 3.5% of alloc_objects alloc_objects: Total: 773496750 773873722 (flat, cum) 7.18% 177 . . parser.fieldIndexes = parser.fieldIndexes[:0] 178 . . 179 . . isEmptyLine := true ... 225 386621314 386621314 str := string(parser.recordBuffer) // Convert to string once to batch allocations 226 386875436 386875436 dst := make([]string, len(parser.fieldIndexes)) * Use pool for mutation This take most alloc in WriteRows: ROUTINE ======================== github.com/pingcap/tidb-lightning/lightning/backend.(*importer).WriteRows in /Users/huangjiahao/go/src/github.com/pingcap/tidb-lightning/lightning/backend/importer.go 797370418 980241246 (flat, cum) 9.09% of Total . . 155: kvs := rows.(kvPairs) ... ... . . 192: for i, pair := range kvs { 772641868 772641868 193: mutations[i] = &kv.Mutation{ . . 194: Op: kv.Mutation_Put, . . 195: Key: pair.Key, . . 196: Value: pair.Val, . . 197: } . . 198: } * Set GC percent as 500 default Lightning allocates too many transient objects and heap size is small, so garbage collections happen too frequently and lots of time is spent in GC component. In a test of loading the table `order_line.csv` of 14k TPCC. The time need of `encode kv data and write` step reduce from 52m4s to 37m30s when change GOGC from 100 to 500, the total time needed reduce near 15m too. The cost of this is the memory of lightnin at runtime grow from about 200M to 700M, but it's acceptable. So we set the gc percentage as 500 default to reduce the GC frequency instead of 100. * Remove MaxKVPairs in Mydump has been move to Importer part * Remove outdate code * Update tidb version For
