Hi,
to revive the processing of branch "joliet_multi_extent" i made some
experiments:
The branch merges without problems with a branch that was freshly
created from "master". So i assume that it is good for "master", too.
I hacked GNU xorriso to create extents of only 16 KiB each.
Macros MAX_ISO_FILE_SECTION_SIZE and ISO_EXTENT_SIZE in libisofs/ecma119.h
were set to 16384. Then i created an ISO image with Joliet and without
Rock Ridge of a file with ~360 KiB (actually /bin/tar):
xorriso -compliance no_emul_toc -padding 0 -joliet on -rockridge off \
-outdev joliet_multi_extent.iso \
-map /bin/tar /FileWithManyExtents
Inspection by
xorriso -indev joliet_multi_extent.iso -toc -find / -exec report_lba --
shows that Joliet was loaded and the file is represented by 22 extents:
Media blocks : 208 readable , 188491924 writable , 188492148 overall
ISO offers : Joliet
ISO loaded : Joliet
...
Report layout: xt , Startlba , Blocks , Filesize , ISO image path
File data lba: 0 , 33 , 8 , 358072 , '/FileWithManyExtents'
...
File data lba: 21 , 201 , 7 , 358072 , '/FileWithManyExtents'
I get from the programs of branch "joliet_multi_extent":
$ iso-info -i joliet_multi_extent.iso -l
...
Joliet Level: 3
...
- [LSN 33] 358072 Nov 08 2014 19:48:38 FileWithManyExtents
$ iso-read --image=joliet_multi_extent.iso \
--extract=FileWithManyExtents --output-file=../tar_from_iso
$ diff tar_from_iso /bin/tar
$
So for me it looks ready for merging.
Other, more realistic experiments would be welcome.
Have a nice day :)
Thomas
