Specs and Algorithm of session snapshot & periodic backup system:
Notepad++ quits without asking for saving unsaved file.
It restores all the unsaved files and document as the states they left.
For existing file (c:\tmp\foo.h)
- Open
In the next session, Notepad++
1. load backup\FILENAME@CREATION_TIMESTAMP (backup\foo.h@198776) if exist, otherwise load FILENAME (c:\tmp\foo.h).
2. if backup\FILENAME@CREATION_TIMESTAMP (backup\foo.h@198776) is loaded, set it dirty (red).
3. if backup\FILENAME@CREATION_TIMESTAMP (backup\foo.h@198776) is loaded, last modif timestamp of FILENAME (c:\tmp\foo.h), compare with tracked timestamp (in session.xml).
4. in the case of unequal result, tell user the FILENAME (c:\tmp\foo.h) was modified. ask user if he want to reload FILENAME(c:\tmp\foo.h)
- Editing
when a file starts being modified, a file will be created with name: FILENAME@CREATION_TIMESTAMP (backup\foo.h@198776)
the Buffer object will associate with this FILENAME@CREATION_TIMESTAMP file (backup\foo.h@198776).
1. sync: (each 3-5 second) backup file will be saved, if buffer is dirty, and modification is present (a bool on modified notificatin).
2. sync: each save file, or close file, the backup file will be deleted (if buffer is not dirty).
3. before switch off to another tab (or close files on exit), check 1 & 2 (sync with backup).
- Close
In the current session, Notepad++
1. track FILENAME@CREATION_TIMESTAMP (backup\foo.h@198776) if exist (in session.xml).
2. track last modified timestamp of FILENAME (c:\tmp\foo.h) if FILENAME@CREATION_TIMESTAMP (backup\foo.h@198776) was tracked (in session.xml).
For untitled document (new 4)
- Open
In the next session, Notepad++
1. open file UNTITLED_NAME@CREATION_TIMESTAMP (backup\new 4@198776)
2. set label as UNTITLED_NAME (new 4) and disk icon as red.
- Editing
when a untitled document starts being modified, a backup file will be created with name: UNTITLED_NAME@CREATION_TIMESTAMP (backup\new 4@198776)
the Buffer object will associate with this UNTITLED_NAME@CREATION_TIMESTAMP file (backup\new 4@198776).
1. sync: (each 3-5 second) backup file will be saved, if buffer is dirty, and modification is present (a bool on modified notificatin).
2. sync: if untitled document is saved, or closed, the backup file will be deleted.
3. before switch off to another tab (or close documents on exit), check 1 & 2 (sync with backup).
- CLOSE
In the current session, Notepad++
1. track UNTITLED_NAME@CREATION_TIMESTAMP (backup\new 4@198776) in session.xml.
