Changing tags doesn't "touch" file (improvement) #8

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
Makes it difficult to enable folder actions, use tools like Hazel, or otherwise 
script things to happen 
on "tag change". Tag time is recorded, and can be used to diff with a "last 
checked" time, but there 
seems to be no filesystem event fired on tag change.

I don't know which way to go on this. I originally was setting the modification 
date of the file ahead by one 
second (as opposed to touching - which sets mod date to 'now', but this causes 
Time Machine to back up the 
entire file again, just to back up 200 bytes of OpenMeta tags, etc. So when I 
added OpenMetaBackup, I pulled 
out the mod date adjustment. 
In any case, I don't think changing the modification date to 'now' with a 
classic touch is the right thing? 

Note that the 'ctime' from lstat() does change on tagging. But it does not fire 
off notifications.

Makes sense. Though losing the tags on restore from a backup would also not be 
ideal. Hopefully good backup 
or sync tools, like DropBox, do binary file diffs.

I am not sure if this is possible, but if the folder the file is contained in 
could be touched that would cause folder 
actions to fire (I think). I am not sure that it has any effect on Time Machine.

I don't think OpenMeta itself should do this. Instead it should be up to the 
app implementing OpenMeta to do 
so. I can imagine many scenarios where changing the modification date would be 
undesirable. If using 
OpenMeta forced me to update the mtime on any tagged file, I'd be unhappy.
