Function Documentation

check_addir()

int check_addir ( int volroot )

static

Check for .AppleDouble folder and .Parent, create if missing

check_adfile()

int check_adfile ( const char * fname, const struct stat * st, const char ** newname )

static

Check for .AppleDouble file, create if missing

check_cnid()

cnid_t check_cnid ( const char * name, cnid_t did, struct stat * st, int adfile_ok )

static

Check CNID for a file/dir, both from db and from ad-file.

Returns

Correct CNID of object or CNID_INVALID (ie 0) on error

check_eafile_in_adouble()

int check_eafile_in_adouble ( const char * name )

static

Check if file cotains "::EA" and if it does check if its correspondig data fork exists.

Returns

0 = name is not an EA file

1 = name is an EA file and no problem was found

-1 = name is an EA file and data fork is gone

check_eafiles()

int check_eafiles ( const char * fname )

static

Check Extended Attributes files

check_netatalk_dirs()

const char * check_netatalk_dirs ( const char * name )

static

Check for netatalk special folders e.g. ".AppleDB" or ".AppleDesktop".

Returns

pointer to name or NULL.

check_orphaned()

int check_orphaned ( const char * name )

static

check_special_dirs()

const char * check_special_dirs ( const char * name )

static

Check for special names.

Returns

pointer to name or NULL.

cmd_dbd_scanvol()

int cmd_dbd_scanvol	(	struct vol *	vol_in,
		dbd_flags_t	flags )

Main func called from cmd_dbd.c

dbd_readdir()

int dbd_readdir ( int volroot, cnid_t did )

static

This is called recursively for all dirs. volroot=1 means we're in the volume root dir, 0 means we aren't. We use this when checking for netatalk private folders like .AppleDB. did is our parent's CNID.

read_addir()

int read_addir ( void )

static

Check files and dirs inside .AppleDouble folder.

Note

remove orphaned files

bail on dirs

remove_eafiles()

void remove_eafiles ( const char * name, struct ea * ea )

static

Remove all files with file::EA* from adouble dir

update_cnid()

int update_cnid ( cnid_t did, const struct stat * sp, const char * oldname, const char * newname )

static

We unCAPed a name, update CNID db
