Re: auto-revert error on macOS when auto-revert-use-notify is t

[zhang cc]

Yes. this seems OK. But there is a delay before auto-revert every 2 appending to the test file.

echo aaa >> test.c   (auto-revert ok)

echo aaa >> test.c   (delay about 4s, then auto-revert ok)

echo aaa >> test.c   (auto-revert ok)

echo aaa >> test.c   (delay about 4s, then auto-revert ok)

…

I added some debug log to two method (name in []):

[file-notify-callback]: (9 (extend write) /Users/jun/test/1.c)

[auto-revert-notify-handler]: (9 changed /Users/jun/test/1.c)

Reverting buffer ‘1.c’.

[file-notify-callback]: (9 (extend write) /Users/jun/test/1.c)

[auto-revert-notify-handler]: (9 changed /Users/jun/test/1.c)

[file-notify-callback]: (9 (extend write) /Users/jun/test/1.c)

[auto-revert-notify-handler]: (9 changed /Users/jun/test/1.c)

[file-notify-callback]: (9 (extend write) /Users/jun/test/1.c)

[auto-revert-notify-handler]: (9 changed /Users/jun/test/1.c)

Reverting buffer ‘1.c’.

3 write events but only one auto-revert.

There is a big delay before auto-reverting, not every one, about every two or three.

You can modify the test file with the following bash script:

#!/bin/bash

for (( i = 0; i < 100; i++ ));

do

        echo $i >> 1.c

        sleep 2

done
