pygrub was unable to parse extlinux config files correctly, exactly
the ones like:
LABEL grsec
KERNEL vmlinuz-3.0.10-grsec
APPEND initrd=initramfs-3.0.10-grsec
root=UUID=cfd4a7b4-8c40-4025-b877-8205f1c622ee
modules=sd-mod,usb-storage,ext4 xen quiet
This patch fixes it, adding a new case when parsing the "append" line,
that searches for the initrd image.

When user wants to change entry in grub2 menu in pygrub, there's no
response in case of appending command line arguments ('a' key).
Append malfunction is caused by change of keyword used for kernel
record. Grub uses 'kernel' for line with linux kernel but grub2 uses
'linux' instead. This patch adds checking for both grub 1 and 2 keywords.

When user wants to change entry in grub2 menu in pygrub, there
may be crash of pygrub in case of editing item ('e' key).
Crash on editing is caused longer entry list in case of grub2. As entry
window is 10 lines high, it can hold only 8 entries (2 lines for border).
Adding line outside of windows high causes crash. Patch add handling
for longer lists and scrolling through them.

grub-mkrescue internally uses xorriso, which generates a so-called
"Hybrid ISO": The ISO images also contains a DOS partition table,
which allows the identical ISO file to be stored on an USB stick for
booting from it. This breaks PyGrub, since it (wrongly) detects only
the DOS partition table and uses the first partition instead of the
complete ISO file.
Add a check to detect HybridISO files and use offset 0 in addition to
partition table parsing.

libxl would rather like to parse the output of pygrub. Rather than
implement an SXP parser in libxl add a --output-format option to
pygrub which can select an alternative, simpler to parse,
format. Available formats are:
sxp: current SXP output format;
simple: simple key+value output with \n separating item ( for
debugging). key and value are separated by a single
space (and key therefore cannot contain a space);
simple0: as simple but with \0 as a separator;
Also add --output-directory to allow temporary files to be placed
somewhere other than /var/run/xend/boot.

This is the patch to fix pyGrub default value when it's being set out of
range. This patch makes the quiet and interactive mode select the same
default image when the default value for boot entry is out of range,
i.e. when the guest is having wrong configuration in it's boot loader
(like 3 entries with default mistakenly set to 10 etc).
When the boot entry number is being set out of range it falls back to 0
(first entry of boot loader).

Use the proper bootloader class when entering the boot commands
manually (i.e. using the 'c' option). Before this patch the bootloader
was always treated to be Grub but when user is using Grub2/ExtLinux or
Lilo it's rather confusing. After applying this patch the proper
bootloader image class is being used, e.g. Grub2Image for Grub2
etc. when you define the boot commands manually using the 'c' command
in pyGrub.
Also, fix for using isconfig has been applied since if there is not fs
set in the run_grub() method the read_config() would fail since it's
trying to access undefined self.cf which is now being set to parser()
from cfg_list.

* The "default" value can be a quoted string (containing an integer)
so strip the quotes before interpreting.
* The "set" command takes a variable with an arbitrary name so instead
of whitelisting the ones to ignore simply silently accept any set
command with an unknown variable.
* Ignore the echo command.
* Handle the function { ... } syntax. Previously pygrub would error
out with a syntax error on the closing "}" because it thought it was
the closing bracket of a menuentry.

Fix the issue when importing 'crypt' module or crypt.crypt fails in
pygrub. The exception is written on the same line like "Failed!"
message but only if there is an exception. If there is no exception,
we don't bother users with details (probably the password they entered
was wrong) so we just display "Failed!" message. Also, the code for
hasPassword() was rewritten not to have try/except block here.

pygrub currently has a hardcoded path of /usr/bin/python which is not
correct if the version of python at install time is not the same as
that at build time. This patch uses the existing install-wrap and
python/get-path machinery.
(It does not address the currently-existing bug that the get-path
machinery works by assuming that `python' is a symlink, rather than
querying the python interpreter for its version.)

It basically checks for the presence of password line in grub.conf
of the guest image and if this line is present, it supports both clear
text and md5 versions of the password. Editing the grub entries and
command-line are disabled when some password is set in domain's
grub.conf file but the password was not entered yet. Also, new option
to press 'p' in interactive pygrub has been added to allow entering
the grub password. It's been tested on x86_64 with PV guests and was
working fine. Also, the countdown has been stopped after key was
pressed, ie. the user is probably editing the boot configuration.

We change all invocations of setup.py as follows:
* use $(PYTHON) instead of `python' so that the user can specify
an alternative python version if they need to. If not set it
defaults to `python' in Config.mk.
* pass --prefix=$(PREFIX) via a new make variable
$(PYTHON_PREFIX_ARG). This allows a user to suppress the
--prefix=... argument entirely by setting PYTHON_PREFIX_ARG=''.
This will work around the bug described here
https://bugs.launchpad.net/ubuntu/+bug/362570
where passing --prefix=/usr/local (which ought to have no effect as
/usr/local is the default prefix) changes which subdirectory
distutils chooses, and results in the files being installed in
site-packages which is not on the default search path.
Users not affected by this python packaging bug should not set
PYTHON_PREFIX_ARG and their builds will not be affected. (Provided
PREFIX did not contain spaces. People who put spaces in PREFIX are
being quite optimistic.)

Previously, by default we would install our python modules into
/usr/lib/python/xen, for example /usr/lib/python/xen/__init__.py.
Upstream python's standard install location (a) includes the Python
version number and (b) puts things in site-packages by default.
Our best conjecture for the reason for this was an attempt to make the
installs portable between different python versions. However, that
doesn't work because compiled python modules (.pyc), and C python
extensions corresponding to one version of python, are not compatible
across different versions of python.
This is why upstream include the version number.
site-packages is the standard location for locally-installed packages
and is automatically included on the python search path.
In this change, we abandon our own unusual python path setup:
* Invoke setup.py in an entirely standard manner. We pass
PREFIX and DESTDIR using the appropriate options provided by
setup.py for those purposes (adding them to setup.py calls
which were previously lacking them).
* Since the installation locations are now on the standard
python path, we no longer need to add anything to the path
in any of our python utilities. Therefore remove all that
code from every python script. (Many of these scripts
unconditionally added /usr/lib/python and /usr/lib64/python which
is wrong even in the old world.)
* There is no longer any special `Xen python path'. xen-python-path
is no longer needed. It is no longer called by anything in our
tree. However since out-of-tree callers may still invoke it, we
retain it. It now prints a fixed string referring to a directory
which does not to exist; callers (who use it to augment their
python path) will thus add a nonexistent directory to their python
path which is harmless.
* Remove various workarounds including use of setup.py --home
(which is intended for something completely different).
* Remove tests for the XEN_PYTHON_NATIVE_INSTALL build-time
environment variable. The new behaviour is the behaviour which we
should have had if this variable had been set. That is, it is now
as if this variable was always set but also bugs in the resulting
install have been fixed.
This should be a proper fix for the bug addressed by c/s 19515.
