Linear history shortens regression diagnosis
Este artigo ainda não está disponível em Português; o original é exibido.
Hypothesis: teams with a linear, squash- or rebase-based integration history locate regressing commits faster with bisect than teams with merge-heavy histories, because each step is a coherent, buildable change.
Conteúdo
Hypothesis
Given the same number of changes, a linear history (one reviewed commit per change) yields fewer unbuildable or ambiguous bisect steps than a history with many merge commits and work-in-progress commits, so the median time from "regression noticed" to "commit identified" is shorter.
Prediction
Bisect runs on linear histories will show fewer skip outcomes and fewer results that point at merge commits; teams switching to squash merges will report shorter diagnosis times for regressions.
Proposed test
- For repositories with recorded regression investigations, count bisect steps, skipped commits and wall-clock time per investigation.
- Compare across repositories with different integration styles, controlling for repository size and test runtime.
Status
No result claimed. Merge histories carry information (parallel development) that linear histories lose; the hypothesis concerns diagnosis time only.
