Rewrites this legacy script behavior using native Python code, using
subprocess module when executing programs like partclone.info or lzop
ogGetImageInfo is a bash script that retrieves information regarding an
OpenGnsys partition image, specifically:
- clonator
- compressor
- filesystem
- datasize (size of the partition image)
This rewrite only supports partclone and lzop compressed images. This is
standard behavior, we have no reports of other programs or compression
algorithms in use.
Keep this legacy function with hungarian notation to emphasize this is
still a legacy component that may be replaced in the future.

Drop ogChangeRepo Bash script in favor of a native Python
approach. Use only necessary subprocess calls instead of bringing
all the logic of this function into a Bash script black box.
ogChangeRepo unmounts the current OpenGnsys image samba folder
(/opt/opengnsys/images) and mounts (connects to) a new directory using
the new provided ip address. Keeping access mode from previous mount.
If anything goes wrong when mounting the new directory, it will fallback
to mounting the previous directory.
If no previous OpenGnsys image samba directory is detected, this
functions tries to mount the new directory anyway. In this case,
it will raise CalledProcessError if something goes wrong.
|

|
|
|
| |
Expand function docstring and do not use CalledProcessError handling to
return True or False. Just checking for returncode value is simpler.

init_cache() creates the default directory in which OpenGnsys stores
images when using any cache enabled transfer method.
As of this commit this folder must exist for tiptorrent.py to
work properly.
Subprocess Popen object inside tiptorrent.py use
'cwd' optional parameter like:
cwd='/opt/opengnsys/cache/opt/opengnsys/images/'
This folder convention might change in the future.

Adds utility module which wraps several mkfs.* calls as a subprocess.
The main utility function is mkfs(fs, disk, partition, label), which
subsequently calls the corresponding mkfs_*(partition_device) function.
mkfs() supports specifying a drive label where supported.
Other modules using fs.py should call mkfs() only.

Fix error paths in live operations which do not
reset the "browser" to the main page (one with the menu).
Add error logging messages when:
* _restartBrowser fails.
* ogChangeRepo fails.
Improve checksum fetch error handling. For example, when an invalid
repository IP is specified.

Raise exception when tiptorrent-client subprocess runs normally but
exits with non-zero code. (For example, if download file allocation
failed)

Integrates image restore command into native ogClient code. Further
reduces the need for external Bash scripts.
After a succesful image restore, OS configuration is still using
external Bash script "osConfigure/osConfigureCustom".

ogCopyEfiBootloader is an invalid legacy bash function name.
Rename to the correct function name 'ogCopyEfiBootLoader' and
rename utility python wrapper too.

Do not return the subprocess result for ogReduceFs/ogExtendFs.
ogReduceFs works with or without the target filesystem mounted.
ogExtendFs requires the target filesystem to be mounted.
'ogMount' legacy script invocation should be replaced by a better
mount/umount wrapper.

Use legacy script that saves the Windows-specific content from the ESP
to the image target filesystem.
Current image restore solution from OpenGnsys scripts expect the EFI
partition to be stored in the target system partition. (Only for Windows
10)
For example, storing the ESP in the NTFS partition of a Windows image.
Expect use of bash script ogCopyEfiBootloader until further
integration is merged.

Integrates some parts of this operation into native code, eg: the md5
checksum computation.
Wraps non native processes and commands using the subprocess module.
For example, legacy.py stores bash commands pending integration.
Supports python >=3.6, expected until more modern ogLives are put into
production environments.

Adds new logging handler redirecting messages to the log file
located in the Samba shared directory (applies to live mode
clients, i.e: ogLive)
Parses log level configuration from ogclient.json. See:
{
"opengnsys": {
...
"log": "INFO",
...
}
...
}
Adds --debug option to set root logger level to DEBUG when starting
ogClient. Overrides log level from config file.
In addition:
- Replaces any occurence of print with a corresponding logging function.
- Unsets log level for handlers, use root logger level instead.
- Default level for root logger is INFO.
- Replaces level from response log messages to debug (ogRest)

Returns true if target is already a mountpoint. Does not call mount.
It's possible that another device might be mounted in the target
mountpoint. A future check between the source and target for
equal device major:minor must be added.

Generates a cache.txt file if a cache partition is detected.
OpenGnsys stores information about stored images in its 'cache'
partition via a text file.
The file is stored in a samba shared directory, mounted at
'/opt/opengnsys/log/' in a live client. The file name is '{ip}.cache.txt'.
Previously, the generation of this file was delegated to external bash
scripts.

OpenGnsys partition images store OS information, including
the OS name appended with "64 bits" when the OS is meant for 64 bit
machines.
The detected OS name when probing (refresh) is important, if it differs
from what's stored in the DB OpenGnsys will wipe last image restored
information when running a refresh.
See actualizaConfiguracion from legacy ogserver (ogAdmServer.c) code:
dato = dbi_result_get_uint(result, "idnombreso");
if (idsoi == dato) {
swu = false;
}
...
if (swu) {
result_update = dbi_conn_queryf(dbi->conn,
"UPDATE ordenadores_particiones SET "
" codpar=0x%s,"
" tamano=%s,"
" uso=%s,"
" idsistemafichero=%d,"
" idnombreso=%d,"
" idimagen=0,"
" idperfilsoft=0,"
" fechadespliegue=NULL"
" WHERE idordenador=%d AND numdisk=%s AND numpar=%s",

is passed without a trailing slash.

Cannot replace str ('\n') when stdout is a bytes object.
Also fixes some typos (i.e: proc_releaseid stdout was used twice).

* disk.py
Disk discovery
* fs.py
Uses psutil to fetch fs usage information
* menu.py
ogBrowser menu generation
* net.py: gets nic status information
IP address, MAC address and ethernet speed.
* probe.py: probes mountpoints for operating systems
Uses hivexget command to try fetching Windows installation
information.
Looks for /etc/os-release for probing linux systems.
