Irina reports that "Partition assistant"/"Asistente de particionado" is
not working. This is happening because ogClient is not reading the full
data ogServer sends when the entire HTTP PDU is larger than 1024.
However, ogClient should read the whole message, reading until read data
length is greater or equal to "Content-Length" header value.
ogClient fails to obtain "Content-Length" value because is looking for
"content-length", be aware of the case sensitivity. It also needs to
take into account the header length because read data length also
includes headers.
This patch updates ogClient to:
1) look for "Content-Length instead of "content-length".
2) compare read date length with content length plus headers
length.
Disconnect gracefully from ogServer after booting OS, the script to start the
OS calls kexec, so everything is gone after it. For Windows, this results in a
reboot.
This commit also improves the disconnect function to make sure the
disconnection is synchronous.
This is useful for debuging and getting information on the processes that are
being executed in ogclient.
syslog outputs are something similar to:
Jun 26 10:36:40 ogAdministrator /ogclient: GET refresh HTTP/1.1
Jun 26 10:36:40 ogAdministrator /ogclient: HTTP/1.0 500 Internal Server Err
When restore image command was sent and the restoration failed, you
could see in WebConsole the image as restored and the command completed,
as it if had not failed. This happened because ogClient did not check
the return code of restoration script.
This commit adds return code check on restore image. So, when return
code is a non-zero value ogClient responses with an error 500. When
ogServer receives this error response, it did not set in the database
the image as restored and command as completed without errors.
From https://www.gnu.org/licenses/gpl-howto.en.html:
"You should also include a copy of the license itself somewhere in the
distribution of your program. All programs, whether they are released under the
GPL or LGPL, should include the text version of the GPL. In GNU programs we
conventionally put the license in a file called COPYING."
This script can be useful to install ogclient on distributions that do not have
an already built ogclient package.
It is necessary to install ogclient in the right path, so the command you have
to use looks similar to:
python3 setup.py install --prefix=/opt/opengnsys/ogclient
--install-lib=/opt/opengnsys/ogclient
--install-script=/opt/opengnsys/ogclient
Improves code encapsulation by moving check_vm_state_loop method into
OgVirtualOperations class. This also fixes import error when running ogclient in
'linux' mode.
Commit 621fb7a7 added class initialization with two parameters. These
two parameters were wrongly initialized, "self." was missing. The call
of these params in other functions of the class was also wrong.
This commit fix the initialization of the parameters of
OgLinuxOperations and fix the calls to these params.
ogClient may runs on an OS that do not have all the dependencies needed
to use virtual functions.
This commit change the behaviour to only import virtual functions when
the ogClient has to work with Virtual Machines. This way ogClient works
on environments which do not need virtual functions.
Ths patch handles different cases when a /refresh request can be made. More
specifically this handles the situation in which the VM is stopped when /refresh
is called but it starts during the processing of /refresh, in this case we just
send the last recorded setup.
This patch:
- Fixes logic errors in the communication with QMP (the order of handshake
messages was not right).
- Rewrite parts of OgQMP class.
- Enforces better coding practices by using Python's "context managers" to avoid
forgeting an open socket in case exceptions occur.
- Adapt virtual operations to the use of "context managers" using the "with"
statement.
This is the device that has the best empirical performance right now and it
seems like it is where most of the qemu development is directed towards for the
future.
ogClient changed its config file format to json. This patch adapts
ogLinuxOperation to use new config file.

This patch waits before polling qemu with QMP so that it has time to be ready
for requests. It also increases wait time in case the host machine is slow.
Write permission is not needed to get information about each virtual drive so
this patch changes permissions to 'only read'. This can prevent race conditions.
This patch calls poweroff in virtual mode when no VM is running and no jobs are
being executed. This is useful when the guest OS shutdowns so that the host OS
does not continue to run.
This patch includes changes to:
- Poweroff VM before running operations that require access to virtual disks.
- Poweroff VM before host system poweroff.
When virtual mode is activated, send the last stored partitions setup because
it is not possible to access a running virtual drive to get its information.
recv method is useful for receiving information that was not previously
requested (such as "events"). This patch also implements automatic handshake
on OgQMP by sending an "qmp_capabilities" request.
We observed that with the new ogClient the ogLive did not show the
realtime log menu*.
This commit changes the ogClient to launch the browser and show the
realtime log menu when some commands are executed.
* The realtime log menu is a menu that shows current status and info
about the command that the ogLive is executing.
We have observed that the ogLive browser did not show the changes when
an image restoration o script execution was called. The problem was that
the HTML menu was not updated/regenerated in these cases.
This commit adds the call to the HTML regeneration function to image
restore and script execution commands. This way, when the browser is
restarted it loads the updated HTML menu.
We have observed that the browser did not show changes. This happens
because the ogClient opens the browser at the beginning and forget
about it. To show correctly the changes ogClient had to restart the
browser every time the menu html changes.
This commit changes the behaviour to restart the browser when the menu
html has changed.
