2407 | 2407 | - S[n-1].ctime < S[n].mtime: means natural advancing (*1) |

2408 | 2408 | - S[n-1].ctime == S[n].mtime: is ambiguous (*2) |

2426 | 2426 | |
|
2427 | 2427 | Advancing mtime "if isambig(oldstat)" ensures "S[n-1].mtime != |

|
2849 | 2849 | # Here we workaround the EINTR issue for fileobj.__iter__. Other methods |

|
2852 | 2852 | # Although we can workaround the EINTR issue for fp.__iter__, it is slower: |
|
2853 | 2853 | # "for x in fp" is 4x faster than "for x in iter(fp.readline, '')" in |
|
2854 | 2854 | # CPython 2, because CPython 2 maintains an internal readahead buffer for |
|
2855 | 2855 | # fp.__iter__ but not other fp.read* methods. |

|
2857 | 2857 | # On modern systems like Linux, the "read" syscall cannot be interrupted |
|

2859 | 2859 | # affects things like pipes, sockets, ttys etc. We treat "normal" (S_ISREG) |
