This same bug is still present under Hardy, hal 0.5.11~rc2-1ubuntu8.2. I just re-ran my test on 7 different disc and it failed on 4 of them. The is_vcd, is_svcd, and is_videodvd properties are missing on audio CDs, blank CDR, blank CDRW, and blank DVDR.
Maybe I'm misunderstanding what "Mandatory" means in the HAL specification, but these missing properties make the API more difficult to use than it should be. I originally encountered this problem working on my DVD ripper (https://launchpad.net/kungfu), for which all I need to check is the is_videodvd property. Unless the check is wrapped in a try/except, my ripper crashes when certain discs are inserted. I know this is kind of nit-picking, but it would be nice if it were fixed. If I have a chance, I'll take a look at it this weekend, but I'm totally unfamiliar with the HAL source, so no promises. ;) Here is the test results: # Audio CD: Fail volume.disc.has_audio = 1 volume.disc.has_data = 0 volume.disc.is_vcd: No property volume.disc.is_svcd: No property volume.disc.is_videodvd: No property volume.disc.is_appendable = 0 volume.disc.is_blank = 0 volume.disc.is_rewritable = 0 volume.disc.capacity = 511047680 volume.disc.type = cd_rom # Video DVD: Okay volume.disc.has_audio = 0 volume.disc.has_data = 1 volume.disc.is_vcd = 0 volume.disc.is_svcd = 0 volume.disc.is_videodvd = 1 volume.disc.is_appendable = 0 volume.disc.is_blank = 0 volume.disc.is_rewritable = 0 volume.disc.capacity = 8318572544 volume.disc.type = dvd_rom # Data CD: Okay volume.disc.has_audio = 0 volume.disc.has_data = 1 volume.disc.is_vcd = 0 volume.disc.is_svcd = 0 volume.disc.is_videodvd = 0 volume.disc.is_appendable = 0 volume.disc.is_blank = 0 volume.disc.is_rewritable = 0 volume.disc.capacity = 735051776 volume.disc.type = cd_r # Data DVD: Okay volume.disc.has_audio = 0 volume.disc.has_data = 1 volume.disc.is_vcd = 0 volume.disc.is_svcd = 0 volume.disc.is_videodvd = 0 volume.disc.is_appendable = 0 volume.disc.is_blank = 0 volume.disc.is_rewritable = 0 volume.disc.capacity = 964493312 volume.disc.type = dvd_r # Blank CDR: Fail volume.disc.has_audio = 0 volume.disc.has_data = 0 volume.disc.is_vcd: No property volume.disc.is_svcd: No property volume.disc.is_videodvd: No property volume.disc.is_appendable = 0 volume.disc.is_blank = 1 volume.disc.is_rewritable = 0 volume.disc.capacity = 4706074624 volume.disc.type = dvd_r # Blank CDRW: Fail volume.disc.has_audio = 0 volume.disc.has_data = 0 volume.disc.is_vcd: No property volume.disc.is_svcd: No property volume.disc.is_videodvd: No property volume.disc.is_appendable = 0 volume.disc.is_blank = 1 volume.disc.is_rewritable = 1 volume.disc.capacity = 735051776 volume.disc.type = cd_rw # Blank DVDR: Fail volume.disc.has_audio = 0 volume.disc.has_data = 0 volume.disc.is_vcd: No property volume.disc.is_svcd: No property volume.disc.is_videodvd: No property volume.disc.is_appendable = 0 volume.disc.is_blank = 1 volume.disc.is_rewritable = 0 volume.disc.capacity = 4706074624 volume.disc.type = dvd_r ** Attachment added: "Slightly updated Python test script" http://launchpadlibrarian.net/17182567/hal_test.py -- Missing mandatory properties on volume.disc https://bugs.launchpad.net/bugs/74540 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
