1 | E2fsprogs 1.21 (June 15, 2001) |
| 2 | ============================== | |
| 3 | ||
| 4 | Added new configure flags which allow a subset e2fsprogs to be built; | |
| 5 | this is most useful for boot floppies, since the resulting shared | |
| 6 | libraries and programs are slimmed down by removing features that | |
| 7 | aren't necessary for a boot floppy. The new flags that were added | |
| 8 | are: --disable-swapfs, which removes support for byte swapping old | |
| 9 | legacy PPC/68k filesystems, --disable-debugfs, which removes support | |
| 10 | for debugfs from the libext2fs library, --disable-imager, which | |
| 11 | removes support for the e2image program, and --disable-resizer, which | |
| 12 | removes support for resize2fs. | |
| 13 | ||
| 14 | E2fsck now prints the number of mounts or days elapsed since the last | |
| 15 | check when e2fsck is forced to check an otherwise clean filesystem. | |
| 16 | ||
| 17 | Tune2fs now prints an informative message about how often a filesystem | |
| 18 | will be checked when adding a journal to the filesystem, to remind the | |
| 19 | user that he/she may want to adjust those parameters using tune2fs | |
| 20 | -c/-i. | |
| 21 | ||
| 22 | Worked around hurd brain-damage which causes e2fsck to sometimes | |
| 23 | believe a filesystem is the root filesystem based on device numbers | |
| 24 | (since Hurd doesn't have dev_t's, which is arguably a POSIX.1 | |
| 25 | violation). | |
| 26 | ||
| 27 | Fixed a bug introduced in 1.20 which caused e2fsck to abort with an | |
| 28 | erroneous error with the -F option was specified. | |
| 29 | ||
| 30 | Fixed a ext3 recovery bug in the revoke handling; synchronized with | |
| 31 | ext3 0.7a. | |
| 32 | ||
| 33 | Fixed two bugs in e2fsck's handling of dup block handling, dealing | |
| 34 | with relatively uncommon edge cases: a directory with an indirect | |
| 35 | block which is claimed by another file, and when the last inode in the | |
| 36 | filesystem has blocks claimed by another file. | |
| 37 | ||
| 38 | E2fsck now checks to see if the i_size field of a fast symlink is too | |
| 39 | big, and offers to clear the symlink if so. | |
| 40 | ||
| 41 | E2fsck now checks to see if i_size_high of special files is non-zero, | |
| 42 | and offers to clear i_size_high. | |
| 43 | ||
| 44 | Fix e2fsck's handling of incompatible journal flags so that the user | |
| 45 | has chance to abort, and then has the option to clear out the journal | |
| 46 | entirely. (Addresses Debian bug #98527.) | |
| 47 | ||
| 48 | Fixed a bug in fsck which could cause it to core dump if a mix of | |
| 49 | standard and non-standard device names are used in /etc/fstab. | |
| 50 | (Debian bug #100559) | |
| 51 | ||
| 52 | Fixed a bug in debugfs which caused read errors when copying a file to | |
| 53 | not be noticed. | |
| 54 | ||
| 55 | The debugfs set_super_value command can now modify the s_lastcheck field. | |
| 56 | ||
| 57 | Fixed a bug in lsattr and chattr which was accidentally introduced in | |
| 58 | 1.20 to support > 2GB files; both lsattr and chattr wasn't reading | |
| 59 | directories correctly because the change modified the layout of struct | |
| 60 | dirent to be incompatible with the libe2p shared library. | |
| 61 | ||
| 62 | Cleaned up the mke2fs manual page and included a discussion about why | |
| 63 | it's good to periodically check the filesystem even when journalling is | |
| 64 | enabled. | |
| 65 | ||
| 66 | Programmer's notes: | |
| 67 | ------------------- | |
| 68 | ||
| 69 | Fix general gcc -Wall complaints. | |
| 70 | ||
| 71 | The types needed by the ext2 header files are now provided by | |
| 72 | lib/ext2fs/ext2_types.h, instead of include/asm/types.h. | |
| 73 | ||
| 74 | Integers are now preferred to longs when trying to find a 32-bit type | |
| 75 | in ext2_types.h. Also, if linux/types.h has already been defined, | |
| 76 | don't try to redefine the types. | |
| 77 | ||
| 78 | Fixed make depend script so that it automatically corrects the | |
| 79 | pathname cleanups performed by make -M, so I don't have to fix them up | |
| 80 | by hand. | |
| 81 | ||
| 82 | Fixed the d_loaddump test case to be more robust, and not depend on | |
| 83 | bash'isms. | |
| 84 | ||
| 85 | Removed debugfs's dependence on pread(), which was accidentally | |
| 86 | introduced in e2fsprogs 1.20 | |
| 87 | ||
| 88 | Fixed a performance bug in the libext2fs's icount routine; the size | |
| 89 | estimate of the icount array was incorrectly being calculated. | |
| 90 | ||
| 91 | Removed use of the badblocks compatibility functions in the e2fsprogs | |
| 92 | programs. | |
| 93 | ||
| 94 | Added paranoia code which protects against strange cases where /etc | |
| 95 | isn't on the root filesystem, or if /etc/mtab doesn't exist. | |
| 96 | ||
| 97 | The header file ext2_types.h is now installed. | |
| 98 | ||
| 99 | Autoconf is used to determine when we are on big-endian machines, | |
| 100 | instead of doing run-time tests, to save a few bytes of code. | |
| 101 | ||
| 102 | The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap | |
| 103 | functions are no longer inline functions, which saves space and | |
| 104 | doesn't really cost any real performance. | |
| 105 | ||
| 106 | The ext2fs library no longer depends on the e2p library. (What need | |
| 107 | there was of it --- namely, fsetflags, was coded in-line). | |
| 108 | ||
| 109 | Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even | |
| 110 | when the user is stupid and tries compiling the package using "make | |
| 111 | install" as root. | |
| 112 | ||
| 113 | Miscellaneous code cleanups: | |
| 114 | * Added missing files from Makefile.in's SRCS file, so that | |
| 115 | their dependencies would be properly calculated. | |
| 116 | * Removed redundant code | |
| 117 | * Fixed comments in code | |
| 118 | * Removed no-longer needed argsused #pragma. | |
