java.lang.Object

jetbrains.buildServer.serverSide.stat.FirstFailedInCache

public class FirstFailedInCache
extends Object

This class is used to keep cached values of FirstFailedIn builds for failed tests. The idea of caching First Failed In values is as follows: When calculating first failed in, we go back through builds history (see BuildTypeTestsCache) and looking for the build where the test is successful (see DetectPreviousFailuresProcessor in BuildStatisticsBuilder). When found, we stop searching and consider the previous failed build as First Failed In. The problem is, if FFI build is not in cached build instances (BuildTypeTestsCache is limited), the repeatable requests to find FFI for a test become lengthy. So, while searching for a FFI build, we track if the returning build data is cached in BuildTypeTestsCache. The first uncached build becomes an anchor for the FFI cache. After the first full scan, for all tests (testNameIds) which have FFI build before the anchor, we cache the FFI build for the pair anchor_buildId+testNameId. On subsequent pass, when we're passing anchored buildId, we take value for FFI build from this cache.

Returns null if value is not in cache, i.e. cache was not popuplated. Returns Optional.empty() if FFI was calculated and was not found Returns Optional.of(ffiBuild) if ffiBuild was calculated, found and placed to cache
