Bug: Can't edit file in symbol link folder

My kernel has a Color Control feature, and its setting is saved in
/sys/class/misc/colorcontrol/v1_offset
v1_offset is the filename, and
colorcontrol is a symbol link folder.
there are two issue:
1. the file size is incorrect. In this case, it is a few byte file, but it show as 4k anyway.
2. long-press then select Edit File, it will prompt error, saying:
Code: Select all
error reading file!
/sys/class/misc/colorcontrol/v1_offset
It is not necessary related to the symbol link, but this is a obvious suspect...

Please check in context menu - properties of the file whether you have the read rights for this file (for all types, owner, group, other).

of course,
BTW, I can use "echo" command to set the feature, as well as other text editor.
Only TC fail to open it

Did you run "echo" with root rights (su command)? The editor does NOT root rights, it can only edit the file if you give everyone access to the file.

yes, echo with root right. But this doesn't explain everythings:
1. I've checked ALL checkbox in the file properties, so I think this is for everyone access ( other text editor open it normally as mentioned )
2. TC can open and edit file in other root-needed access folder files
3. doesn't explain why the file size is incorrect.

Maybe you changed the rights of the link? This doesn't give you the right to read the data from the actual file.

The problem should not relate to symbol link, go the the actual directory and try opening the file, issue remain.
if it's about access right, that doesn't explain why other plain text editor can open and save as normal after granted the root right when prompt.
And TC behave strange in those folder too, can't mount as RW, saying
Note: other application can access those file at the same time, so it's not true about "resource busy"
P.S.
personally, I don't think it is necessary to mark out symbol link by default, that make the layout a little chaos in some case...
and finally, a feature request:
would you consider making the highlighted toolbar always show at top? it's annoying sometime when scroll up and down in folder with many file, like /sdcard/
back & forward are also nice to have

Because Totalcmd's editor is NOT a root editor, it can only edit files to which you have read and write rights as a normal user.

chmod 777 to the folder & the file, nothing changes. It doesn't match "resource busy" error message when trying remount the folder if it's a permissions issue as well.
And just check another file, in
/system/etc/init.d/
permission setting: -rwx -rx -rx, TC built-in editor open / edit it normally
