Age	Commit message (Collapse)	Author
2016-02-01	Un-shorten some lines that don't need breaking anymore. Remove a couple of	Kenneth R Westerback
	indent levels by shuffling code bit.
2016-01-31	Nuke pointless map field 'physical_block' and just use 'sbBlkSize' which is	Kenneth R Westerback
	set to the same value.
2016-01-31	Use delete_entry()/create_entry() in delete_partition_from_map() instead of	Kenneth R Westerback
	trying to be clever and tweaking the existing entry into a free space entry by manual manipulation of the fields.
2016-01-31	Fold add_data_to_map() into create_entry() as the former is always called	Kenneth R Westerback
	immediately after the latter, manipulating fields in the same structure. Use create_entry() in create_partition() rather than doing the same actions manually.
2016-01-31	Don't use add_data_to_map() when reading from disk, since it resets some	Kenneth R Westerback
	of the dpme_ fields, overwriting data from disk. Add some paranoia checks for map limits when reading from disk.
2016-01-31	Just call contains_driver() when you need to know rather than carrying a	Kenneth R Westerback
	flag around. More obviously current data. Nuke unnecessary variables when displaying a partition.
2016-01-31	Apple sets lblock_start and lblocks to 0 in free space entries. Do	Kenneth R Westerback
	the same. Don't use lblock_start or lblocks in calculation for length@base display. We no longer display lblock info there.
2016-01-30	Move last three lines (#define's) from dpme.h to partition_map.h and	Kenneth R Westerback
	tweak #include's as necessary.
2016-01-30	Fold struct dpme into struct entry. Same reasons as for folding	Kenneth R Westerback
	struct block0 into struct partition_map. Easier to read code.
2016-01-30	Refactor add_partition_to_map() to be simpler if perhaps less	Kenneth R Westerback
	performance optimized. New logic will simplify merging struct dpme into struct entry.
2016-01-30	There is not much to do if we run out of memory, so simply exit if	Kenneth R Westerback
	a malloc() or calloc() fails. Simplifies a bunch of logic, makes add_data_to_map() always succeed or exit, so make it a void.
2016-01-29	Fold struct block0 into struct partition map. There can be only one	Kenneth R Westerback
	and read/write_block0() can move the data from/to disk to/from appropriate fields anywhere. Removes a bunch of dereferencing, malloc'ing and pointer checking.
2016-01-29	Warn of partitions extending past the end of the media.	Kenneth R Westerback

2016-01-29	Shorter names means a few whitespace adjustments.	Kenneth R Westerback

2016-01-29	Rename struct partition_map_header to struct partition_map. No change to	Kenneth R Westerback
	.o files.
2016-01-29	Rename struct partition_map to struct entry. No change to .o files.	Kenneth R Westerback

2016-01-29	Conform to Apple Mac OS X's behaviour of setting dpme_flags on free	Kenneth R Westerback
	partitions to 0, and setting them to VALID \| ALLOCATED on the map partition.
2016-01-29	Conform to Apple Mac OS X's behaviour of not giving 'Apple_Free'	Kenneth R Westerback
	partitions a name. Nuke kFreeName.
2016-01-28	Flip base_order to a LIST().	Kenneth R Westerback

2016-01-28	Delete a bunch of Morris dancing in delete_partition_from_map().	Kenneth R Westerback
	No need to create a new dpme. Just rename/retype the existing and let combine_entry() suck in any surrounding empty space partitions.
2016-01-28	Hand rolled lists suck. First, replace disk_order with an LIST.	Kenneth R Westerback

2016-01-28	Oops. Deleted one too many lines. Need to advance pointer when traversing	Kenneth R Westerback
	list.
2016-01-28	When adding a new partition to the map, use only existing mapped	Kenneth R Westerback
	space. Don't try to create new free space partitions to use. If the map does not know about all of the space on the disk, it is broken.
2016-01-28	Since we don't allow maps to be created or opened with an invalid	Kenneth R Westerback
	block0, there is no point in checking later if block0 has magically become invalid.
2016-01-28	Use consistent 'return' idiom -- no parenthesis since that was the style	Kenneth R Westerback
	of the existing code.
2016-01-28	Make 'r' (reorder, a.k.a. swap) command work with any two existing	Kenneth R Westerback
	partitions. Do NOT allow partition 1 to be moved!
2016-01-27	Traverse next_by_base when checking maps coverage, not next_on_disk!	Kenneth R Westerback

2016-01-27	We do not support logical_block != physical_block. Remove logical_block	Kenneth R Westerback
	field and left over code that checks for logical != physical. Removes confusion with dmpe fields lblock_start and lblocks, which have nothing to do with block sizes! lblock_start is the block offset within the partition where the data actually starts. and lblocks is the number of blocks of data within the partition. Both are in units of physical blocks, a.k.a. disk sectors.
2016-01-27	Check block 0 signature, physical block size and physical block count when	Kenneth R Westerback
	reading partition map. Check for unmapped physical blocks and overlapping partitions when reading partition map. No need for duplicate checks in validate_map(), so remove validate.c from build and 'v' command from code and docs.
2016-01-27	Nuke another (and I hope final) batch of superfluous '{}' around single	Kenneth R Westerback
	statements.
2016-01-26	dpme_name and dpme_type are NUL-terminated in Apple code, so use	Kenneth R Westerback
	strlcpy() to fill them. They are also supposed to be NUL-padded so zap previous contents before copying in possibly shorter new values.
2016-01-26	Whitespace, line wrapping fixes. Nuke many superfluous '{}' around single	Kenneth R Westerback
	statements. 0 -> NULL for pointer checks.
2016-01-26	Whitespace, line wrapping fixes.	Kenneth R Westerback

2016-01-26	Simplify logic of read_partition_map(), junking retries with various sizes	Kenneth R Westerback
	of logical block. Rely on read_dpme() to do the correct thing.
2016-01-25	Use new read/write_block0 and read/write_dpme which handle any	Kenneth R Westerback
	endian or alignment issues forcefully. Removes need for convert_* functions so unhook convert.c from build. read/write_block become static functions inside file_media.c. Tweak struct block0 to stop trying to handle alignment issues by clever declaration. Rely on the new functions to accurately translate between on-disk and in-memory layouts. Enables pdisk to work on amd64 and likely other architectures if it's ever desirable. Does bring back DEV_BSIZE to pdisk.c since the in-memory structure will not be 512 bytes on other archs.
2016-01-24	Whitespace.	Kenneth R Westerback

2016-01-24	Nuke get_align_long() and put_align_long() #define's. They don't do	Kenneth R Westerback
	anything according to gcc & cmp. cmp suggested by & ok stefan@.
2016-01-24	Whitespace fixes.	Kenneth R Westerback

2016-01-24	Delete duplicated line that was setting sbBlkCount to 0; Score one	Kenneth R Westerback
	for the 'v' command!
2016-01-23	Nuke unused kPatchType. Nuke kStringNot and use " not' where needed.	Kenneth R Westerback
	Nuke kStringEmpty and use "" where needed. Nuke unused static 'g'. Eliminate #include's in *.h files. Some whitespace fixes.
2016-01-23	Pass the disk sector size to open_partition_map(), eliminating it's	Kenneth R Westerback
	internal need for DEV_BSIZE. Ditto create_partition_map(). malloc((sizeof(struct [block0\|dpme])) instead of malloc(DEV_BSIZE). Remove another #include <param.h>.
2016-01-23	Add comments to ensure future spelunkers realize that struct block0	Kenneth R Westerback
	and struct dpme must be 512-bytes long at the moment. Use this fact to avoid using DEV_BSIZE and thus replace #include <param.h> with #include <types.h> in pdisk.c. Constrain media size to UINT32_MAX, the actual limit, instead of LONG_MAX, which could be way more on some theoretical future arch running pdisk. And do the constraint inside open_partition_map().
2016-01-23	Avoid double prompt after creating default map on startup.	Kenneth R Westerback

2016-01-23	Flip read_block() and write_block() back to taking sector addresses	Kenneth R Westerback
	instead of off_t values. Do the DEV_BSIZE multiplication in these two functions. Easier to read code and kills two #include <sys/param.h>. Kill unused label.
2016-01-23	map->block0 is always allocated or the map is discarded.	Kenneth R Westerback
	So stop checking for NULL. Nuke get_block_zero() and just use map->block0.
2016-01-23	Nuke sync_device_size() and do it's one-field-update in coerce_block0(),	Kenneth R Westerback
	right after we read/allocate media->block0. Doing sync before media->block0 is allocated is bad. The map->physical_block is initialized correctly and never to the magic number '1'. So just use map-physical_block to initialize sbBlkSize.
2016-01-23	Always initialize media_size to provided mediasz in open_partition_map().	Kenneth R Westerback

2016-01-23	Break annoying long line.	Kenneth R Westerback

2016-01-22	Change partition map field 'data' to 'dmpe'. Change 'create_data'	Kenneth R Westerback
	to 'create_dmpe'. Sweep up some 'struct dpme data' to struct dpme dpme'.
2016-01-22	Rename map field 'misc' to 'block0' since that's what it is.	Kenneth R Westerback
