afprun()

int afprun ( char *  cmd, int *  outfd  )

extern

run a command

Note

being careful about uid/gid handling and putting the output in outfd (or discard it if outfd is NULL).

close_all_vol()

void close_all_vol

(

const AFPObj *

obj

)

closevol()

void closevol	(	const AFPObj *	obj,
		struct vol *	vol
	)

get_tm_bands()

static long long int get_tm_bands ( const char *  path )

static

Return number on entries in a directory.

Parameters

[in]

path

path to dir

Returns

number of entries, -1 on error

get_tm_bandsize()

static long long int get_tm_bandsize ( const char *  path )

static

Read band-size info from Info.plist XML file of an TM sparsebundle.

Parameters

[in]

path

path to Info.plist file

Returns

band-size in bytes, -1 on error

get_tm_used()

static int get_tm_used ( struct vol *  vol )

static

Calculate used size of a TimeMachine volume.

This assumes that the volume is used only for TimeMachine.

1. readdir(path of volume)
2. for every element that matches regex "\‍(.*\‍)\.sparsebundle$" :
3. parse "\1.sparsebundle/Info.plist" and read the band-size XML key integer value
4. readdir "\1.sparsebundle/bands/" counting files
5. calculate used size as: (file_count - 1) * band-size

The result of the calculation is returned in "volume->v_tm_used". "volume->v_appended" gets reset to 0. "volume->v_tm_cachetime" is updated with the current time from time(NULL).

"volume->v_tm_used" is cached for TM_USED_CACHETIME seconds and updated by "volume->v_appended". The latter is increased by X every time the client appends X bytes to a file (in fork.c).

Parameters

vol	(rw) volume to calculate

Returns

0 on success, -1 on error

getvolparams()

static int getvolparams ( const AFPObj *  obj, uint16_t  bitmap, struct vol *  vol, struct stat *  st, char *  buf, size_t *  buflen  )

static

getvolspace()

static int getvolspace ( const AFPObj *  obj, struct vol *  vol, uint32_t *  bfree, uint32_t *  btotal, VolSpace *  xbfree, VolSpace *  xbtotal, uint32_t *  bsize  )

static

pollvoltime()

int pollvoltime

(

AFPObj *

obj

)

poll if a volume is changed by other processes.

Parameters

obj	AFP connection object

Returns

0 no attention msg sent, 1 attention msg sent, -1 error (socket closed)

Note

if attention return -1 no packet has been sent because the buffer is full, we don't care either there's no reader or there's a lot of traffic and another pollvoltime will follow

server_ipc_volumes()

static void server_ipc_volumes ( AFPObj *  obj )

static

Send list of open volumes to afpd master via IPC

setvoltime()

void setvoltime	(	AFPObj *	obj,
		struct vol *	vol
	)

stat_vol()

static int stat_vol ( const AFPObj *  obj, uint16_t  bitmap, struct vol *  vol, char *  rbuf, size_t *  rbuflen  )

static

vol_setdate()

static void vol_setdate ( uint16_t  id, struct adouble *  adp, time_t  date  )

static

set volume creation date

Note

avoid duplicate, well at least it tries
