Tables can only handle 2^64 inserts into a table when using auto increment instead of 2^64 total entries.

Tables Affected:
keys

emacs was renaming with an ~ at the end
not sure what gedit does

key cache
metadata cache
hardlink cache
datapath cache
dynamic hierarchy

A datapath op should also query for and return the datainode. This should then be used instead of asking the file system by using get_inode.

Non-critical but should be done. Program will still work regardless

The hardlink name is correct.

Possible issues with how emacs performs edits. Possible issues with all programs that backup files in a similar way.

A user opens the file.
Emacs opens file: filetest1.txt
Emacs reads the contents of filetest1.txt into memory.

The user changes the file
Emacs renames filetest1.txt to filetest1.txt~

When a user saves the open file:
Emacs creates a new file and writes the contents of the buffer to it.
Emacs renames the new file to filetest1.txt

Now the metadata is tied to filetest1.txt~ and not filetest1.txt.

rewrote string allocation code to copy path items
need to go through all source code and free items

Function: jfs_file_rename

rename /dirtest1/.goutputstream-BXSWRV /dirtest1/foldertest2.txt
