int ops__build_path	(	char **	value,

	)

-.

Return the path of this entry.

This function uses a rotating array of cache_entry_t. This means that a few paths will be usable at once; if some path has to be stored for a (possibly indefinite) time it should be strdup()ed, or re-built upon need.

A LRU eviction scheme is used - with last one marked.

If some function modifies that memory, it should set the first char to \0, to signal that it's no longer valid for other users.

Todo:: A further optimization would be to check if a parent is already present, and append to that path. Similar for a neighbour entry.

The cache_entry_t::id member is used as a pointer to the struct estat.

Calculate the length of the path for this entry.

This function returns the number of characters needed. We don't return success or failure; there should never be a problem, and if we'd return 0 for success someone might put a STOPIF() in the recursive call below, which would double the size of this function :-)

We don't include the trailing \0, as that would be counted on each level.

The function to go through the lists.

only_A, both, and only_B are called, then for_every (if not NULL).

This builds and loops throught the sts::by_name lists, so modifying them must be done carefully, to change only the elements already processed.

Returning an error from any function stops the loop.

Only one the 3 specifications my be given; the other 2 values must be a NULL resp. UNKNOWN_INDEX.

If the entry is given via sts, but is not found, ENOENT is returned.

If an invalid index is given, we mark a BUG().

Fills sts from a buffer where.

The filename still points into the buffer (mmap()ed area) and must be copied.

mem_pos is advanced, and points after the \0. If a \n is seen immediately afterwards, it is skipped, too.

parent_i gets set to the stored value; the translation to a parent pointer must be done in the caller.

EOF cannot be reliable detected here; but we are guaranteed a \0\n at the end of the string, to have a filename termination.

Writes a textual description of the given sts to the filehandle.

The parameter parent_ino is a(n integer) reference to the parent directory - the line number in which it was written. The format is fixed (see ops__dir_info_format_p); the string includes a \0 for filename termination, and a \n at the end.

Any other characters that are allowed in a filename can be written - even control characters like \n, \r, \f and so on.

int ops__string_to_dev	(	struct estat *	sts,
		char *	data,
		char **	info
	)

-.

Converts a string describing a special node to the struct sstat_t data.

info, if not NULL, gets the pointer to the first character after the parsed text: For a symlink it is returned as the path it points to, devices are fully decoded and should a pointer to \0.

	)

-.

Create or find an entry below parent.

Does not modify path.

The flags parameter tells about the policy regarding tree walking.

For add, unversion we need to create the given path with the specified flags; in add it should exist, for unversion is needs not. For diff / info we only walk the tree without creating or checking for current status (info, repos/repos diff for removed files). For prop_set / prop_get / prop_list we need an existing path, which might be not versioned currently. For revert we need to look in the tree, and find removed entries, too. In waa__partial_update() (status check with given subtrees) we create the paths as necessary. If they do not exist we'd like to print them as removed.

So we need to know:

Create paths or walk only (OPS__CREATE)
Has the given path to exist? (OPS__FAIL_NOT_LIST)
- Should we update this entry, or all below? (OPS__ON_UPD_LIST)
Which flags the newly created entries should get (in sts_flags)

int ops__update_filter_set_bits ( struct estat * sts )

-.

Wrapper for ops__update_single_entry and some more.

Calls ops__set_to_handle_bits() and maybe ops__update_single_entry(), and depending on the filter settings sts->do_this_entry might be cleared.

Here is the caller graph for this function:

int ops__update_single_entry	(	struct estat *	sts,
		struct sstat_t *	output
	)

-.

Does a lstat() on the given entry, and sets the entry_status.

The parent directory should already be done, so that removal of whole trees is done without doing unneeded lstat()s.

Depending on o_chcheck a file might be checked for changes by a MD5 comparision.

Per default only_check_status is not set, and the data from lstat() is written into sts. Some functions need the old values and can set this flag; then only entry_status is modified.

If output is not NULL, then it is overwritten, and sts->st is not changed - independent of only_check_status. In case of a removed entry *output is not changed.

const char link_spec[] = "link "

Startstrings for links in the repository.

It's a bit unaesthetical that devices use a " " for the repository data, but a ":" in the waa as delimiter. But "link " is specified in subversion, and having the repository data different would not be better. So we just allow both at parsing, and use the "right" for each target.
