二分(bisect)缺陷
+++++++++++++++++++
(英文版)最後更新:2016年10月28日
引言
=====
始終嘗試由來自kernel.org的源代碼構建的最新內核。如果您沒有信心這樣做,請將
錯誤報告給您的發行版供應商,而不是內核開發人員。
找到缺陷(bug)並不總是那麼容易,不過仍然得去找。如果你找不到它,不要放棄。
儘可能多的向相關維護人員報告您發現的信息。請參閱MAINTAINERS文件以瞭解您所
關注的子系統的維護人員。
在提交錯誤報告之前,請閱讀“Documentation/admin-guide/reporting-issues.rst”。
設備未出現(Devices not appearing)
====================================
這通常是由udev/systemd引起的。在將其歸咎於內核之前先檢查一下。
查找導致缺陷的補丁
===================
使用 ``git`` 提供的工具可以很容易地找到缺陷,只要缺陷是可復現的。
操作步驟:
- 從git源代碼構建內核
- 以此開始二分 [#f1]_::
$ git bisect start
- 標記損壞的變更集::
$ git bisect bad [commit]
- 標記正常工作的變更集::
$ git bisect good [commit]
- 重新構建內核並測試
- 使用以下任一與git bisect進行交互::
$ git bisect good
或::
$ git bisect bad
這取決於您測試的變更集上是否有缺陷
- 在一些交互之後,git bisect將給出可能導致缺陷的變更集。
- 例如,如果您知道當前版本有問題,而4.8版本是正常的,則可以執行以下操作::
$ git bisect start
$ git bisect bad # Current version is bad
$ git bisect good v4.8
Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
