hfsutils-3.1 released
by Rob Leslie 12 Nov '97

12 Nov '97

-----BEGIN PGP SIGNED MESSAGE----- I am pleased to announce the availability of a new line of `hfsutils' development. PLEASE NOTE! Beginning with this release, the version number of the release gives an indication of the expected quality-of-release. Releases are numbered X.Y[.Z] where X is the major version, Y is the minor version, and Z is a patch-release version. Even-numbered Y numbers represent "stable" releases. Odd-numbered Y numbers represent "development" releases. Development releases may not be as well-tested as the stable ones, although they may contain many more features and improvements. Once a development tree has been tested enough to be believed to be stable, a new stable release will be made to reflect this. Version 3.1 of hfsutils is now available here: ftp://ftp.mars.org/pub/hfs/ A number of improvements have been made over version 2.0, including: * A new internal block cache; multiple consecutive volume blocks are read and written with fewer system calls, and are cached for efficiency. The result is an enormous performance boost on many platforms. * Three bug fixes: - the alternate MDB was sometimes written to the wrong location on non-partitioned media; - the Extents Overflow file could become corrupted under some circumstances in which a heavily fragmented file is removed; and - it was possible for the volume allocation routine to become caught in an infinite loop. * Character set translation (MacOS Standard Roman <=> ISO8859-1 [Latin-1]) now occurs when copying text files, in addition to end-of-line conversion. * Several libhfs API changes: - hfs_create() now returns an open file reference like hfs_open(); - hfs_format() accepts a list of bad blocks which are to be spared; - hfs_mount() and hfs_format() now require the given partition number to exist, or allow 0 to specify the entire medium; and - new routines hfs_zero(), hfs_mkpart(), hfs_nparts() allow new partition maps and HFS partitions to be created and counted; * Entire package is now configured via a GNU `configure' script. Details for the new, simplified installation procedure can be found in the distributed `README' file. * Many other minor improvements. A number of people have asked recently about the potential for HFS+ support (aka Sequoia or Extended Format) in this package. The answer is yes, I have already begun to implement support for HFS+ volumes. This will become available in a stable release beginning with version 4.0. I have reason to believe it may be technically possible to convert standard HFS volumes into HFS+ volumes without the need to reformat; if so, I plan to include a utility to do this as well. In the meantime, I should note that I currently have very limited access to real HFS+ machines for testing -- and therefore any contributions (in the form of time or hardware :-) are extremely welcome. I would appreciate your feedback on this software. You may send me email directly, or give feedback on the hfsutils web page: http://www.mars.org/home/rob/proj/hfs/ Cheers, - -- Robert Leslie rob(a)mars.org -----BEGIN PGP SIGNATURE----- Version: 2.6.3 Charset: noconv Comment: Processed by Mailcrypt 3.4, an Emacs/PGP interface iQCVAwUBNGkJm22QJIfwC8CVAQHelgP/fZPJyn500jMwUODCTtU3uXo+xfNbABaa cqtOaLPtbigVoE00P7USU9xCr56gAetvTbvza0AgYKLot4a6dlBqd8v5gPXtx4l4 fHuTZaJGroBnhVAht9bneHEc0Xudqy/80m7sRpPxHXcpJQVTBuB1vzg7ejCFaVXk 5jjPUVAXlXo= =gwEB -----END PGP SIGNATURE-----

hfs-interest mailing list problems
by Rob Leslie 12 Nov '97

12 Nov '97

Greetings. I recently discovered a problem with the <hfs-interest(a)ccs.neu.edu> mailing list. Although the list tends to be extremely quiet most of the time, it's possible that any number of message sent in the last few months have been lost or sent only to a very small number of subscribers. It's also possible that you tried to unsubscribe from this list but you're still on the subscriber list (as evidenced by your receipt of this message). If this is the case for you, I apologize, and you can rectify the situation by sending the following email: To: majordomo(a)ccs.neu.edu unsubscribe hfs-interest If you continue to have any problems, please notify me, the list maintainer, and I will take care of the matter. Sincerely, -- Robert Leslie rob(a)mars.org
