* utils: rename inventory.py to sw_inventory.pyJose M. Guisado2023-04-181-0/+0
| | | | | | | | Rename software inventory file to sw_inventory to better distinguish it from a future hardware inventory code. In the future sw_inventory and hw_inventory might be merged together once each file is tidied up.
* live: rewrite software inventoryv1.2.7Jose M. Guisado2023-03-271-0/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | Replace legacy bash script in favor of Python code. Improves error traceability and further development. The software inventory operation mounts the target partition and it fetches the list of installed software (package set). Once the operation is complete, it unmounts the target partition. For Windows, introduce hivex library python bindings for accessing Windows registry hive files (https://libguestfs.org/hivex.3.html). This operation is still processed by legacy code in the server side (ogAdmServer.c in ogServer). Legacy backend process expects the software inventory like the following example: "software": "Windows 10 Enterprise Evaluation 2004 \nIntel(R) Network Connections 24.0.0.11 24.0.0.11 ..." The os name is inserted first in this list followed by a '\n' separated string of the software packages. The legacy server code can be found in function actualizaSoftware at ogServer/src/ogAdmServer.c It is expected for software inventory payload to change in the future to a simpler solution using just a json array of strings.
* legacy: improve readability of ogGetImageInfo helper functionsJose M. Guisado2023-03-101-14/+13
| | | | | | | | | | | | | | | | | | | | Change the name of the helper functions used when getting opengnsys image information (legacy ogGetImageInfo bash script). As of now the process consist of decompressing the image file with lzop and feeding that output to partclone.info. Prefer a more explicit function name rather than "process_image_*" Add comment about skipping the first two lines of partclone.info output. Usually, partclone.info starts printing out these two lines that are not related to the partclone image information: Partclone v0.3.23 http://partclone.org Showing info of image (-) As long as partclone.info output doesn't change we'll be fine, but we should not depend on human readable output. This might change in the future (i.e. adding json output format to partclone.info).
* legacy: rewrite ogGetImageInfoJose M. Guisado2023-03-021-14/+104
| | | | | | | | | | | | | | | | | | | | 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.
* legacy: rewrite ogChangeRepoJose M. Guisado2023-03-021-6/+52
| | | | | | | | | | | | | | | | 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.
* legacy: improve readability of cambiar_accessoJose M. Guisado2023-03-021-10/+10
| | | | | Expand function docstring and do not use CalledProcessError handling to return True or False. Just checking for returncode value is simpler.
* utils: add init_cache functionJose M. Guisado2023-02-081-0/+12
| | | | | | | | | | | | | | | 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.
* utils: add fs.pyJose M. Guisado2023-02-081-1/+66
| | | | | | | | | | | 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.
* live: improve error pathsv1.2.3Jose M. Guisado2022-11-171-2/+9
| | | | | | | | | | | | | 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.
* tiptorrent: improve raised exceptions for tip_client_getJose M. Guisado2022-09-291-4/+2
| | | | | | Raise exception when tiptorrent-client subprocess runs normally but exits with non-zero code. (For example, if download file allocation failed)
* live: rewrite image_restoreJose M. Guisado2022-09-142-6/+49
| | | | | | | | 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".
* utils: add tiptorrent.pyJose M. Guisado2022-09-141-0/+90
| | | | | Utility and wrapper functions related to the usage of tiptorrent. To be used by the image restore command.
* utils: add get_partition_deviceJose M. Guisado2022-09-141-0/+17
| | | | | Maps a disk and partition number to the corresponding device path ('/dev/sdXY', '/dev/nvmeXnYpZ', ...)
* image_restore: fix ogCopyEfiBootLoaderJose M. Guisado2022-09-141-3/+4
| | | | | | | | | ogCopyEfiBootloader is an invalid legacy bash function name. Rename to the correct function name 'ogCopyEfiBootLoader' and rename utility python wrapper too. Fixes: 0bd037c1a409c65fbcb01355ee0dd6dca770330e
* utils: minor fix for ogReduceFs and ogExtendFsJose M. Guisado2022-09-141-10/+10
| | | | | | | | | | 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.
* image_create: add legacy ogCopyEfiBootloaderJose M. Guisado2022-09-141-0/+10
| | | | | | | | | | | | | | 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.
* image_create: partial integration into pythonv1.2.2Jose M. Guisado2022-08-242-1/+82
| | | | | | | | | | | 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.
* src: improve loggingJose M. Guisado2022-06-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
* utils: mount_mkdir success if target is a mountpointJose M. Guisado2022-06-011-0/+6
| | | | | | | | 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.
* live: generate cache.txt file in refreshJose M. Guisado2022-06-011-0/+69
| | | | | | | | | | | | | 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.
* probe: detect 64 bit operating systemsJose M. Guisado2022-05-092-2/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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",
* utils: fix winreghives path stringJose M. Guisado2022-04-281-1/+1
| | | | | | | Adds missing slash in the windows reghives path f-string. When calling os_probe inside refresh (live/ogOperations) the mountpoint is passed without a trailing slash.
* live: detect cache partitions in new refreshJose M. Guisado2022-04-281-0/+9
| | | | | | | Detects OpenGnsys cache partition when building the partition setup of a live system. OpenGnsys labels a Linux/ext4 partition as "CACHE".
* utils: decode probing subprocess stdoutJose M. Guisado2022-04-271-2/+2
| | | | | | Cannot replace str ('\n') when stdout is a bytes object. Also fixes some typos (i.e: proc_releaseid stdout was used twice).
* Add utils modulesJose M. Guisado2022-04-215-0/+273
* 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.
