From 0306ad0100b9d40606d723706f909438a27dfac1 Mon Sep 17 00:00:00 2001 From: Pascal Rigaux Date: Tue, 27 Jul 2004 10:31:34 +0000 Subject: - add field {fs_type} partially replacing {pt_type} {pt_type} is always a number, {fs_type} is always a string - introduce set_isFormatted() (to ensure {notFormatted} but also {fs_type_from_magic} and {bad_fs_type_magic} are updated) - don't use 0x483 for ext3 anymore (same for reiserfs...), the type_name gives both a pt_type and a fs_type - many accessors from partition_table removed (type2fs(), fs2pt_type()) - remove isThisFs() (not useful anymore since we can use directly {fs_type}) - remove isFat() (inline the function) - other isXXX() from partition_table are moved to fs::type - part2name() is now fs::type::part2type_name - name2pt_type() is now fs::type::type_name2subpart() - partition_table::important_types() is now fs::type::type_names() - fsedit::typeOfPart() is now fs::type::fs_type_from_magic() - no need to truncate type_name since they are shorter --- perl-install/fs/type.pm | 334 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 334 insertions(+) create mode 100644 perl-install/fs/type.pm (limited to 'perl-install/fs/type.pm') diff --git a/perl-install/fs/type.pm b/perl-install/fs/type.pm new file mode 100644 index 000000000..90d2f3ad0 --- /dev/null +++ b/perl-install/fs/type.pm @@ -0,0 +1,334 @@ +package fs::type; # $Id$ + +use diagnostics; +use strict; + +use common; + + +our @ISA = qw(Exporter); +our @EXPORT = qw( + isExtended isTrueLocalFS isTrueFS isDos isSwap isSunOS isOtherAvailableFS isRawLVM isRawRAID isRAID isLVM isMountableRW isNonMountable isPartOfLVM isPartOfRAID isPartOfLoopback isLoopback isMounted isBusy isSpecial isApple isAppleBootstrap isWholedisk isHiddenMacPart isFat_or_NTFS + maybeFormatted set_isFormatted +); + + +my (%type_name2pt_type, %type_name2fs_type, %fs_type2pt_type, %pt_type2fs_type, %type_names); + +{ + my @list_types = ( + important => [ + 0x82 => 'swap', 'Linux swap', + 0x83 => 'ext2', 'Linux native', + 0x83 => 'ext3', 'Journalised FS: ext3', + 0x83 => 'reiserfs', 'Journalised FS: ReiserFS', +if_(arch() =~ /ppc|i.86|ia64/, + 0x83 => 'xfs', 'Journalised FS: XFS', +), +if_(arch() =~ /ppc|i.86/, + 0x83 => 'jfs', 'Journalised FS: JFS', +), +if_(arch() =~ /i.86|ia64|x86_64/, + 0x0b => 'vfat', 'FAT32', +), +if_(arch() =~ /ppc/, + 0x401 => 'apple', 'Apple Bootstrap', + 0x402 => 'hfs', 'Apple HFS Partition', +), + ], + + less_important => [ + 0x8e => '', 'Linux Logical Volume Manager', + 0xfd => '', 'Linux RAID', + ], + + special => [ + 0x0 => '', 'Empty', + 0x05 => '', 'Extended', + 0x0f => '', 'W95 Extended (LBA)', + 0x85 => '', 'Linux extended', + ], + + backward_compatibility => [ + 0x183 => 'reiserfs', 'reiserfs (deprecated)', + 0x283 => 'xfs', 'xfs (deprecated)', + 0x383 => 'jfs', 'jfs (deprecated)', + 0x483 => 'ext3', 'ext3 (deprecated)', + ], + + other => [ + if_(arch() =~ /^ia64/, + 0x100 => '', 'Various', +), if_(arch() =~ /^ppc/, + 0x401 => 'apple', 'Apple Partition', +), if_(arch() =~ /^sparc/, + 0x01 => 'ufs', 'SunOS boot', + 0x02 => 'ufs', 'SunOS root', + 0x03 => 'ufs', 'SunOS swap', + 0x04 => 'ufs', 'SunOS usr', + 0x05 => 'ufs', 'Whole disk', + 0x06 => 'ufs', 'SunOS stand', + 0x07 => 'ufs', 'SunOS var', + 0x08 => 'ufs', 'SunOS home', +), if_(arch() =~ /^i.86/, + 0x01 => 'vfat', 'FAT12', + 0x02 => '', 'XENIX root', + 0x03 => '', 'XENIX usr', + 0x04 => 'vfat', 'FAT16 <32M', + 0x06 => 'vfat', 'FAT16', + 0x07 => (arch() =~ /^ppc/ ?
