我正在運行基於我的tornado.testing.AsyncHTTPTestCase
的測試用例,偶爾會在日誌中看到此堆棧跟蹤。它似乎是隨機發生的,所以多次運行測試套件有時會遇到這種情況。Tornado 3.2 OverflowError:無法將負int轉換爲無符號
這是一個tornado 3.2錯誤還是我應該處理這個異常一些如何?
它似乎並沒有影響我的任何測試結果,但我對於像這樣留下的隨機異常並不滿意。

OverflowError: can't convert negative int to unsigned
沒有花哨的IOStream東西,我可以看到。如果是這樣,我預計每次運行測試套裝時都會提高OverflowError。現在就像每30次一次。 – MyGGaN
嗯。你可以嘗試從github上的master分支安裝Tornado嗎?在發佈3.2版之後修復了垃圾收集的關閉套接字時出現了一些問題。我不太清楚他們是如何導致這種症狀的(因爲如果IOSteram仍在使用它們,他們不會收集垃圾),但值得一試。 –
我已經簽出了關於龍捲風大師的最新消息,但仍然是同樣的問題。我會花一些時間來看看我能找到什麼測試造成這種情況。 – MyGGaN
