similar to: [PATCH 1/3] ext2: create a struct for the OCaml 't' type

Obviously for very large files this is going to be a problem, as well as not being very cache efficient. libext2fs can handle writes to parts of files just fine so copy files in blocks. Also demote the "Permission denied" error to a warning, and add some explanatory text telling people not to use sudo. --- src/ext2fs-c.c | 127 +++++++++++++++++++++++++++++++++++----------------------

The ext2 filesystem on disk format has two ways to store symlinks. For symlinks >= 60 bytes in length, they are stored as files (so-called "slow symlinks"). For shorter symlinks the symlink is stored in the inode ("fast symlinks"). Previously we only created slow symlinks even if there are shorter than 60 bytes. This didn't matter until recently, when a change went

Check early that there are enough free blocks to store each file, erroring out with ENOSPC if not; this avoids slightly more obscure errors later on. --- src/ext2fs-c.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/src/ext2fs-c.c b/src/ext2fs-c.c index f01ca9d..e45980a 100644 --- a/src/ext2fs-c.c +++ b/src/ext2fs-c.c @@ -52,6 +52,9 @@ /* fts.h in glibc is broken,

We created symlinks in two steps, by creating the empty inode and then calling ext2fs_symlink to populate it. This created broken symlinks where the directory name contained a / character, eg: lrwxrwxrwx 1 root root 7 Nov 26 08:43 /bin -> usr/bin lrwxrwxrwx 1 root root 7 Nov 26 08:43 /lib -> usr/lib lrwxrwxrwx 1 root root 9 Nov 26 08:43 /lib64 -> usr/lib64 lrwxrwxrwx 1

From: "Richard W.M. Jones" <rjones@redhat.com> This plugin allows you to create a complete ext2 filesystem in a GPT partitioned disk image. This can be attached as a disk to a Linux virtual machine. It is implemented using libext2fs (the same as supermin). Although there is some overlap with nbdkit-iso-plugin and nbdkit-floppy-plugin, the implementations and use cases of all

Hi, to ease debugging issues with appliances (e.g. when used in libguestfs), using --include-packagelist will add a file containing the list of all the packages used.

Hi, the two patches improve the way memory is handled in supermin, by cleanly exiting on memory allocation failures, and free'ing memory when not needed (to keep working and not run out of memory).

Hello, This patch adds rollback support for the converter, the converter can roll back a conversion if the image file haven't been modified.

This patch introduce extent buffer cache for every i-node. By this way, we can save the search time and reduce the lock contention of the root because we needn''t search the item from the root of b+ tree. Implementation: - add two pointers of extent buffer into btrfs_inode struct, one for nodes/leaves of fs/file tree, the other for nodes/leaves of the log tree. - add a variant to tell

Turns out Japanese trains are good for coding! In supermin we have a bunch of code to create the libguestfs appliance. It creates it directly using libext2fs (part of e2fsprogs). We can use the same technique to create ext2 virtual disks in nbdkit, which is what this new plugin does. Why a new plugin instead of modifying the floppy plugin? See the 4/4 commit message for an explanation. The

Another interesting thing you can do with this plugin: https://rwmj.wordpress.com/2019/02/19/nbdkit-linuxdisk-plugin/ v2: - Fix inconsistent tab/space. - All 3 plugins now contain a block of text pointing to the other 2 plugins. - TMDIR -> TMPDIR - Unlink the temporary file and other cleanups along error paths. - fclose -> pclose, and check the return value for errors. -

For high-availability Asterisk when using PRI Lines, you might also want to check out our product (FSV-4PFS). It's available at www.failsafevoip.com Bill Also to add to the last post does this device have hardware echo cancelation? if it does it could be a great replacement, if not may not be what I'd really want to use.

Hi to all, I'm trying to run a Canadian income tax program called FutureTax2010 (www.futuretax.ca) under wine 1.2 and 1.3 beta, but there appears to be a regression. It runs under wine 1.0.1, and loads OK under 1.3, but when I try to open an existing (known valid) file FT pops up a message box that says "An unsupported operation was attempted". A screen shot of the end result of
