(pointer, index, etc) in fi->fh, and use this in other all other file operations (read, write, flush, release, fsync). Filesystem may also implement stateless file I/O and not store anything in fi->fh. There PORT is set in fuse_conn_info.capable, this is treated as success and future calls to open and release will also succeed without being sent to the filesystem process.

表示发布候选版本,空白表示正式版。 Curve所有功能开发均在master分支进行,而版本发布则在相应的release分支进行: 从master拉出一个新分支release-x.y,打beta版标签后,提交QA团队测试 ; beta版的bug修复代码先合入master分支,再cherry-pick到release-x.y分支; beta版bug修复完成后,打rc版标签(可能有多个rc版),上线到测试环境; 经bug修复和长时间运行测试后,若代码达到正式上线标准,则发布正式版。 v1.0.0-beta v1.1.0-beta master v1.1.0-rc0 release-1.1 v1.0.0-rc0 v1.0.0 v1.0.1 release-1.0 v1.0.0-rc1 新功能 Bug修复 cherry-pick 11/33测试方法论 从测试粒度看,测试可以分为单元测试、集成测试、系统测试;0 码力 | 33 页 | 2.64 MB | 5 月前3OID CND Asia Slide: CurveFS
