M. J. Fromberger	1dca1a8f97	Performance improvements for the event query API (#7319 ) Rework the implementation of event query parsing and execution to improve performance and reduce memory usage. Previous memory and CPU profiles of the pubsub service showed query processing as a significant hotspot. While we don't have evidence that this is visibly hurting users, fixing it is fairly easy and self-contained. Updates #6439. Typical benchmark results comparing the original implementation (PEG) with the reworked implementation (Custom): ``` TEST TIME/OP BYTES/OP ALLOCS/OP SPEEDUP MEM SAVING BenchmarkParsePEG-12 51716 ns 526832 27 BenchmarkParseCustom-12 2167 ns 4616 17 23.8x 99.1% BenchmarkMatchPEG-12 3086 ns 1097 22 BenchmarkMatchCustom-12 294.2 ns 64 3 10.5x 94.1% ``` Components: * Add a basic parsing benchmark. * Move the original query implementation to a subdirectory. * Add lexical scanner for Query expressions. * Add a parser for Query expressions. * Implement query compiler. * Add test cases based on OpenAPI examples. * Add MustCompile to replace the original MustParse, and update usage.	3 years ago
M. J. Fromberger	cf7537ea5f	cleanup: Reduce and normalize import path aliasing. (#6975 ) The code in the Tendermint repository makes heavy use of import aliasing. This is made necessary by our extensive reuse of common base package names, and by repetition of similar names across different subdirectories. Unfortunately we have not been very consistent about which packages we alias in various circumstances, and the aliases we use vary. In the spirit of the advice in the style guide and https://github.com/golang/go/wiki/CodeReviewComments#imports, his change makes an effort to clean up and normalize import aliasing. This change makes no API or behavioral changes. It is a pure cleanup intended o help make the code more readable to developers (including myself) trying to understand what is being imported where. Only unexported names have been modified, and the changes were generated and applied mechanically with gofmt -r and comby, respecting the lexical and syntactic rules of Go. Even so, I did not fix every inconsistency. Where the changes would be too disruptive, I left it alone. The principles I followed in this cleanup are: - Remove aliases that restate the package name. - Remove aliases where the base package name is unambiguous. - Move overly-terse abbreviations from the import to the usage site. - Fix lexical issues (remove underscores, remove capitalization). - Fix import groupings to more closely match the style guide. - Group blank (side-effecting) imports and ensure they are commented. - Add aliases to multiple imports with the same base package name.	3 years ago
