Reimplement these so they read /proc/mounts instead of trying to parse
the output of the 'mount' external command.
One consequence of this is that these commands now work again for
ntfs-3g filesystems.
|
| |
|
|
|
|
|
|
|
|
| |
The particular issue is that ntfs-3g (or FUSE?) no longer appears
to update /etc/mtab, which meant that umount-all was not unmounting
these partitions. But parsing /proc/mounts is simpler and more
robust in any case.

As a previous, incorrect attempt to fix RHBZ#576879 we tried to
prevent the daemon from sending an error reply if the daemon had
cancelled the transfer. This is wrong: the daemon should send an
error reply in these cases.
A simple test case is this:
guestfish -N fs -m /dev/sda1 upload big-file /
(This fails because the target "/" is a directory, not a file.)
Prior to this commit, libguestfs would hang instead of printing an
error. With this commit, libguestfs prints an error.
What is happening is:
(1) Library is uploading
a file (2) In the middle of the long
upload, daemon detects an error.
Daemon cancels.
(3) Library detects cancel,
sends cancel chunk, then waits
for the error reply from the
daemon. (4) Daemon is supposed to send
an error reply message.
Because step (4) wasn't happening, uploads that failed like this would
hang in the library (waiting for the error message, while the daemon
was waiting for the next request).
This also adds a regression test.
This temporarily breaks the "both ends cancel" case (RHBZ#576879c5).
Therefore the test for that is disabled, and this is fixed in the next
patch in the series.
This partially reverts commit dc706a639eec16084c0618baf7bfde00c6565f63.

Since Fedora util-linux 2.19, the %post script does:
rm -f /etc/mtab
ln -s /proc/mounts /etc/mtab
We are no longer running %post scripts, so this means that /etc/mtab
is a plain file in the appliance. Usual 'mount' still updates it, but
for some reason mount.ntfs does *not* update it in Fedora 15, meaning
that you couldn't mount and then operate on NTFS partitions.
It seems better to always parse /proc/mounts (ie. what the kernel
thinks is mounted) unconditionally, rather than relying on the
capriciousness of the external mount command.
Therefore, parse /proc/mounts instead of /etc/mtab, but add a note
saying that in future we should really be parsing
/proc/self/mountinfo, but that needs a custom parser, and the format
is rather tricky:

We used to maintain a global flag 'root_mounted' which tells us if the
user has mounted something on root (ie. on the sysroot directory).
This flag caused a lot of trouble (eg. RHBZ#599503) because it's hard
to keep the flag updated correctly when the user can do arbitrary
mounts and also use mkmountpoint.
Remove this flag and replace it with a test to see if something is
mounted on *or under* the sysroot. (It has to be *or under* because
of mkmountpoint and friends).
This also replaces a rather convoluted "have we mounted root yet"
check in the mount* APIs with a simpler check to see if the mountpoint
exists and is an ordinary directory.

This reverts commit ad2abf89c364d5ec73fb12af63b053637d99d757.
Ubuntu still has errors even with the addition of udev_settle
after umount-all. Therefore this was just masking the problem.
|
| |
|
|
|
|
| |
This helps avoid an error on Ubuntu, but it's not clear if this
is a real solution or just helps by adjusting the timing of some
race condition.

During a FileIn command (eg. upload, tar-in) if both sides
experience errors, then both sides could send cancel messages,
the result being lost synchronization.
The reason for the lost synch was because the daemon was ignoring
this case and sending an error message back which the library side
(which had cancelled) was not expecting.
Fix this by checking in the daemon for the case where the library
also cancels during daemon cancellation, and not sending an error
messages.
This also includes an enhanced regression test which checks for this
case.
This extends the original fix in
commit 5922d7084d6b43f0a1a15b664c7082dfeaf584d0.

Modify the generator so that it can correctly handle early
cancellation for Pathname|Device|.. parameters. This fixes
the upload command, but consequently we need to fix the
parameters for tar_in and t?z_in commands. This should also
mean that 'win:' can now be used as the second argument of
tar_in and t?z_in commands in guestfish, whereas previously
this wouldn't have worked.
Adds a regression test for the original problem.

The RPC stubs already prefix the command name to error messages.
The daemon doesn't have to do this. As a (small) benefit this also
makes the daemon slightly smaller.
Code in the daemon such as:
if (argv[0] == NULL) {
reply_with_error ("passed an empty list");
return NULL;
}
now results in error messages like this:
><fs> command ""
libguestfs: error: command: passed an empty list
(whereas previously you would have seen ..command: command:..)

Nearly every file-related function in daemons/*.c is affected:
Remove this pair of statements from each affected do_* function:
- NEED_ROOT (return -1);
- ABS_PATH (dir, return -1);
and change the type of the corresponding parameter to "const char *".
* src/generator.ml: Emit NEED_ROOT just once, even when there are two or
more Pathname args.
|

run this command:
git grep -l -w NEED_ROOT|xargs perl -pi -e \

Currently /sysroot is hard-coded throughout the daemon code.
This patch turns the path into a variable so that we can change
it in future, for example to allow standalone mode to be implemented.
This patch was tested by running all the C API tests successfully.

These specialized commands are used to create additional mountpoints
before mounting filesystems. They are only used where you want to
mount several unrelated or read-only filesystems together, and need
additional care to use correctly.
Here is how to use these calls to unpack the "Russian doll" nest
of a Fedora 11 live CD:
add-ro Fedora-11-i686-Live.iso
run
mkmountpoint /cd
mkmountpoint /squash
mkmountpoint /ext3
mount /dev/sda /cd
mount-loop /cd/LiveOS/squashfs.img /squash
mount-loop /squash/LiveOS/ext3fs.img /ext3
The inner filesystem is now unpacked under the /ext3 mountpoint.

Loop device mounts don't work for the generic 'mount' commands
because the first parameter should be a file not a device.
We want to separate out files parameters from device parameters
in the long term, so this adds a new mount-loop command for this
purpose.
