Support for other VCSs can be added by subclassing this class, and overriding methods _vcs_*() with code appropriate for your VCS. The methods _u_*() are utility methods available to the _vcs_*() methods. Sink to existing root ====================== Consider the following usage case: You have a bug directory rooted in /path/to/source by which I mean the '.be' directory is at /path/to/source/.be However, you're of in some subdirectory like /path/to/source/GUI/testing and you want to comment on a bug. Setting sink_to_root=True when you initialize your BugDir will cause it to search for the '.be' file in the ancestors of the path you passed in as 'root'. /path/to/source/GUI/testing/.be miss /path/to/source/GUI/.be miss /path/to/source/.be hit! So it still roots itself appropriately without much work for you. File-system access ================== BugDirs live completely in memory when .sync_with_disk is False. This is the default configuration setup by BugDir(from_disk=False). If .sync_with_disk == True (e.g. BugDir(from_disk=True)), then any changes to the BugDir will be immediately written to disk. If you want to change .sync_with_disk, we suggest you use .set_sync_with_disk(), which propogates the new setting through to all bugs/comments/etc. that have been loaded into memory. If you've been living in memory and want to move to .sync_with_disk==True, but you're not sure if anything has been changed in memory, a call to .save() immediately before the .set_sync_with_disk(True) call is a safe move. Regardless of .sync_with_disk, a call to .save() will write out all the contents that the BugDir instance has loaded into memory. If sync_with_disk has been True over the course of all interesting changes, this .save() call will be a waste of time. The BugDir will only load information from the file system when it loads new settings/bugs/comments that it doesn't already have in memory and .sync_with_disk == True. Allow storage initialization ======================== This one is for testing purposes. Setting it to True allows the BugDir to search for an installed Storage backend and initialize it in the root directory. This is a convenience option for supporting tests of versioning functionality (e.g. .duplicate_bugdir). Disable encoding manipulation ============================= This one is for testing purposed. You might have non-ASCII Unicode in your bugs, comments, files, etc. BugDir instances try and support your preferred encoding scheme (e.g. "utf-8") when dealing with stream and file input/output. For stream output, this involves replacing sys.stdout and sys.stderr (libbe.encode.set_IO_stream_encodings). However this messes up doctest's output catching. In order to support doctest tests using BugDirs, set manipulate_encodings=False, and stick to ASCII in your tests. if root == None: root = os.getcwd() if sink_to_existing_root == True: self.root = self._find_root(root) else: if not os.path.exists(root): self.root = None raise NoRootEntry(root) self.root = root # get a temporary storage until we've loaded settings self.sync_with_disk = False self.storage = self._guess_storage() if assert_new_BugDir == True: if os.path.exists(self.get_path()): raise AlreadyInitialized, self.get_path() if storage == None: storage = self._guess_storage(allow_storage_init) self.storage = storage self._setup_user_id(self.user_id) # methods for getting the BugDir situated in the filesystem def _find_root(self, path): ''' Search for an existing bug database dir and it's ancestors and return a BugDir rooted there.
