我在測(cè)試我的項(xiàng)目時(shí)遇到了 DATA RACE 警告，想知道是否有人愿意幫助我破譯這個(gè)問(wèn)題。我過(guò)去從未嘗試過(guò)測(cè)試 go 例程，我發(fā)現(xiàn)很難全神貫注于數(shù)據(jù)競(jìng)爭(zhēng)。我在未解決問(wèn)題的描述中提供了一個(gè)鏈接，并在問(wèn)題描述中提供了跟蹤。我真的很感激一些幫助，只是從學(xué)習(xí)調(diào)試類似問(wèn)題和為將來(lái)的 go 例程編寫更好的測(cè)試方面。https://github.com/nitishm/vegeta-server/issues/52下面還提供了跟蹤的片段=== RUN Test_dispatcher_Cancel_Error_completedINFO[0000] creating new dispatcher component=dispatcherINFO[0000] starting dispatcher component=dispatcherINFO[0000] dispatching new attack ID=d63a79ac-6f51-486e-845d-077c8c76168a Status=scheduled component=dispatcher==================WARNING: DATA RACERead at 0x00c0000f8d68 by goroutine 8: vegeta-server/internal/dispatcher.(*task).Complete() /Users/nitishm/vegeta-server/internal/dispatcher/task.go:116 +0x61 vegeta-server/internal/dispatcher.run() /Users/nitishm/vegeta-server/internal/dispatcher/task.go:213 +0x17aPrevious write at 0x00c0000f8d68 by goroutine 7: vegeta-server/internal/dispatcher.(*task).Run() /Users/nitishm/vegeta-server/internal/dispatcher/task.go:107 +0x12a vegeta-server/internal/dispatcher.(*dispatcher).Run() /Users/nitishm/vegeta-server/internal/dispatcher/dispatcher.go:109 +0xb5fGoroutine 8 (running) created at: vegeta-server/internal/dispatcher.(*task).Run() /Users/nitishm/vegeta-server/internal/dispatcher/task.go:105 +0x11c vegeta-server/internal/dispatcher.(*dispatcher).Run() /Users/nitishm/vegeta-server/internal/dispatcher/dispatcher.go:109 +0xb5fGoroutine 7 (running) created at: vegeta-server/internal/dispatcher.Test_dispatcher_Cancel_Error_completed() /Users/nitishm/vegeta-server/internal/dispatcher/dispatcher_test.go:249 +0x545 testing.tRunner() /usr/local/go/src/testing/testing.go:827 +0x162

據(jù)我所知：
Read at 0x00c0000f8d68 by goroutine 8:和Previous write at 0x00c0000f8d68 by goroutine 7
意味著 goroutines8和7正在讀取和寫入相同的位置。如果您查看錯(cuò)誤指向的行：
goroutine 8上116：
if?t.status?!=?models.AttackResponseStatusRunning?{goroutine 7上107：
t.status?=?models.AttackResponseStatusRunning
您可以看到 goroutinestask在沒有任何同步的情況下訪問(wèn) 的狀態(tài)，正如您已經(jīng)知道的那樣，這可能會(huì)導(dǎo)致競(jìng)爭(zhēng)條件。
因此，如果您的程序允許多個(gè) goroutine 訪問(wèn)單個(gè)任務(wù)，您需要確保不會(huì)發(fā)生數(shù)據(jù)競(jìng)爭(zhēng)，例如使用互斥鎖。
