This graph shows which files directly or indirectly include this file:

Defines
#define	FSVS_DEBUG_ENV "FSVS_DEBUGLEVEL"
	If this variable has a numeric value other than 0, the debuglevel is set even before commandline parsing.
#define	DIFF_ENV "FSVS_DIFF"
	The diff program to use.
#define	DEFAULT_WAA_PATH "/var/spool/fsvs"
	The default WAA path.
#define	DEFAULT_CONF_PATH "/etc/fsvs"
	The default CONF path.
#define	DEFAULT_CONFIGDIR_SUB "/auth"
	The default config directory (for authentication data), relative to $FSVS_CONF.
#define	CONFIGDIR_GROUP "groups"
	The directory below $CONF/$WC and $CONF for the grouping definitions.
#define	FSVS_EXP_CURR_ENTRY "FSVS_CURRENT_ENTRY"
	The (relative) path of the current entry.
#define	FSVS_EXP_WC_CONF "FSVS_WC_CONF"
	The configuration directory for the current working copy.
#define	FSVS_EXP_WC_ROOT "FSVS_WC_ROOT"
	The current working copy root directory.
#define	FSVS_EXP_TARGET_REVISION "FSVS_TARGET_REVISION"
	The revision we're updating or reverting to.
#define	CHOWN_FUNC lchown
#define	CHOWN_BOOL 1
#define	UTIMES_FUNC lutimes
#define	UTIMES_BOOL 1
List of environment variables used for a chroot jail.
Note that these are not `#ifdef` - marked, as we'd like to use off-the-shelf binaries from newer distributions without modifications!
#define	CHROOTER_ROOT_ENV "FSVS_CHROOT_ROOT"
	The file descriptor number where FSVS can find the "original", "normal" root directory.
#define	CHROOTER_LIBS_ENV "FSVS_CHROOT_LIBS"
	Which libraries should be preloaded? Space-separated list.
#define	CHROOTER_CWD_ENV "FSVS_CHROOT_CWD"
	The old working directory file descriptor.
Manber-parameters
These should be written to a property for big files, so that they can be easily read before fetching the file. We need the same values for fetching as were used on storing - else we cannot do some rsync-like update. Note: Currently they are used only for checking whether a file has changed locally. Here they should be written into the md5s file.
#define	CS__APPROX_BLOCKSIZE_BITS (17)
	How many bits must be zero in the CRC to define that location as a block border.
#define	CS__MANBER_BITMASK ((1 << CS__APPROX_BLOCKSIZE_BITS)-1)
	The bit mask for comparing.
#define	CS__MANBER_MODULUS (-1)
	The modulus.
#define	CS__MANBER_PRIME (31)
	The prime number used for generation of the hash.
#define	CS__MANBER_BACKTRACK (2*1024)
	The number of bytes for the block comparison.
#define	CS__MIN_FILE_SIZE (256*1024)
	The minimum filesize, at or above which files get tested in blocks.
