* utils: add functions to obtain disk and partition UUIDsAlejandro Sirgo Rica2024-07-291-0/+25
| | | | | | | | Add get_partition_id and get_disk_id to obtain the UUID of a disk or partition as a string. These values are obtained invoking the program blkid as a subprocess. This commit is preparatory work for the new native postinstall code.
* src: log backtrace in unhandled error casesAlejandro Sirgo Rica2024-04-031-5/+6
| | | | | | | | | | | | | | | | | | | Log an error message in known error cases and log a backtrace otherwise. Define a new error type OgError to be used in all the 'raise' blocks to define the error message to log. The exception propagates until it reaches send_internal_server_error() where the exception type is checked. If the type is OgError we log the exception message. Logs the backtrace for other types. The initial error implementation printed a backtrace everytime an error ocurred. The next iteration changed it to only print a backtrace in a very particular case but ended up omiting too much information such as syntax errors or unknown error context. The actual implementation only logs the cases we already cover in the codebase and logs a bracktrace in the others, enabling a better debugging experience.
* utils: refine log when booting windows UEFI from DOS partitionOpenGnSys Support Team2024-04-011-1/+1
| | | | | | Refine 97647c32aa2c utils: add enforce_gpt argument to get_efi_partition() to provide more explicit error when trying to boot Windows UEFI from DOS partition.
* utils: add enforce_gpt argument to get_efi_partition()Alejandro Sirgo Rica2024-03-261-3/+6
| | | | | | | The Windows bootloader only supports a UEFI boot from a GPT partition. Set enforce_gpt to True in every codepath related to Windows. When enforce_gpt is set to True get_efi_partition() raises an exception when an MBR partition scheme is detected.
* utils: add disk index checks in get_partition_deviceAlejandro Sirgo Rica2024-03-211-1/+5
| | | | | Control the possibility of a bad disk index. Handle the checks in a similar fashion to the get_efi_partition function.
* utils: improve logging in the get_efi_partition functionAlejandro Sirgo Rica2024-03-081-13/+16
| | | | | Log each partition that gets checked and make the exception messages more informative.
* disk: add get_efi_partition functionJose M. Guisado2024-03-041-0/+24
| | | | | | | | | | | | | Add utility function inside disk.py to find, if any, the first ESP partition of a given disk. The disk is provided as an integer (starting at 1 following OpenGnsys scripts usual values), meaning the (n-1)th disk from the disk array returned from get_disks(). In the future a better mechanism should be put in place to fetch probed disks from a running client. This change is part of the upcoming drop of "IniciarSesion" script in favor of a Python native approach. Specifically regarding UEFI systems.
* src: improve error check in image_create and image_restoreAlejandro Sirgo Rica2024-02-141-1/+1
| | | | | | | | | cover more error cases where exceptions need to be raised. check return code in the invoked subprocess. restoreImageCustom has been intentionally left behind, it is unclear what this custom script returns on success and error.
* 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', ...)
* Add utils modulesJose M. Guisado2022-04-211-0/+19
* 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.
