* live: report LINUX-SWAP instead of SWAPv1.3.2-8OpenGnSys Support Team2024-05-071-0/+3
| | | | | | | ogCP expects LINUX-SWAP to specify a swap filesystem. Add a similar workaround to the one that is done for VFAT for symmetry between inputs and outputs that circulate over the API.
* live: rewrite log in case tiptorrent client failsOpenGnSys Support Team2024-05-061-1/+1
| | | | | Specify that image file cannot be found in cache because tiptorrent has failed, otherwise it is confusing.
* live: restore partprobe before building filesystemOpenGnSys Support Team2024-05-061-1/+4
| | | | Otherwise mkfs silently fails because OS reports out-of-sync partition table.
* live: force flush to disk after partition table is writtenOpenGnSys Support Team2024-05-061-0/+1
|
* live: partprobe breaks with mounted partitionsOpenGnSys Support Team2024-05-061-2/+11
| | | | | | | | | | partprobe requires that all disk partitions are unmounted. partprobe needs to be called to report the OS that the partition table has changed, otherwise ogclient reports incorrect partition information. iterate over the partition list and mount cache after partprobe is called.
* live: umount all partitions before partition setupOpenGnSys Support Team2024-05-061-2/+3
| | | | | If new partition layout is specified, unmount cache and any other partition under /mnt.
* live: fix omited error report in tip_client_getAlejandro Sirgo Rica2024-05-061-7/+6
| | | | | | | tip_client_get raises the proper error exceptions but the except block in _restore_image_tiptorrent overwrites the reported error. Move the raise statements in _restore_image_tiptorrent outside of the except block.
* live: add fat32 to get_parttype()OpenGnSys Support Team2024-04-231-0/+2
| | | | | | Use "Microsoft basic data partition" to store FAT32 in case of GPT partition scheme and 0xB according in case of MBR partition scheme according to documentation.
* live: revisit logging for partition setup, image create and restoreOpenGnSys Support Team2024-04-231-7/+5
|
* utils: add logging for checksum validationOpenGnSys Support Team2024-04-221-3/+9
| | | | Display if checksum validation is correct or not.
* utils: fs: incorrect indentationOpenGnSys Support Team2024-04-221-1/+1
|
* utils: fs: skip shrink/extend operation for fatOpenGnSys Support Team2024-04-191-0/+4
| | | | fat does not support this operation, skip it
* utils: fs: remove unused variable in _reduce_resize2fsv1.3.2-7OpenGnSys Support Team2024-04-191-1/+0
| | | | ret is set but never used in this method
* utils: fs: report error when failing to growOpenGnSys Support Team2024-04-191-2/+2
| | | | not really a warning, report an error instead
* utils: fs: set return value in ogReduceFsOpenGnSys Support Team2024-04-191-2/+3
| | | | | | | | otherwise error path uses uninitialized variable File "/opt/opengnsys/ogClient/src/utils/fs.py", line 112, in ogReduceFs return ret UnboundLocalError: local variable 'ret' referenced before assignment
* live: improve exception handling in image_createAlejandro Sirgo Rica2024-04-031-27/+34
| | | | | | | | | | | | | | | | | Reduce the scope of the try except block that controls the case of deleting the image backup in case of error. Now it only covers the section of code after backup creation and up to image verification. Check when the Exception is an OgError to raise with added context. Prevent the deletion of the target image in case of error before the backup creation. Bundle the backup creation on its own try except block to give more feedback on a failed backup creation. Enables a better error management allowing unhandled exceptions to be reported properly.
* src: use explicit exception types in except Exception blocksAlejandro Sirgo Rica2024-04-033-6/+6
| | | | | | | | Capture only the relevant exception types in each except block. The capture of the Exception type means hiding information for unhandled error cases, even for syntax errors in the codebase. Using a more fine grained exception filtering improves error traceability.
* src: log backtrace in unhandled error casesAlejandro Sirgo Rica2024-04-0314-91/+108
| | | | | | | | | | | | | | | | | | | 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.
* qmp: incorrect copyright headerOpenGnSys Support Team2024-04-021-7/+5
| | | | Replace incorrect copyright header in qmp.py file.
* 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.
* Revert "live: improve lzop and partclone error handling"OpenGnSys Support Team2024-04-011-46/+27
| | | | | | | | This reverts commit 57787dab5499a38915b5e2f702844553abd2ea2a. Read from stderr is blocking if no data is available, revert this patch since ogClient hangs indefinitely in lzop invocations due to races in process execution through Popen.
* utils: fix mount error messages for os probe operationsAlejandro Sirgo Rica2024-04-012-2/+2
| | | | | | | | Replace unexistent mountpoint variable to report a failed mount operation before an OS probe from a partition. Improve the semantics of the error message replacing 'at' with 'into'. Remove the period at the end of the log message.
* live: display info logging when restoring image startsOpenGnSys Support Team2024-03-271-2/+2
| | | | instead of using debug level, this is very useful to track the process.
* live: use .ant image as main image after image creation errorAlejandro Sirgo Rica2024-03-271-0/+6
| | | | | | | Restore image file from .ant to original file name if new image creation fails. Remove new imagen and move the .ant image file in place of the original as previously an error meant a rename of the image file without a revert to keep the image available.
* utils: make init_cache() use the cache mountpointAlejandro Sirgo Rica2024-03-261-1/+1
| | | | | | Make init_cache() use the actual cache mountpoint returned by the function mount_cache() for the creation of the cache directories instead of a hardcoded path.
* utils: remove redundant return statements from mount_mkdirAlejandro Sirgo Rica2024-03-261-3/+1
| | | | | | Remove return statement the program won't reach and simplify the return logic with a return from an if and a fallback return statement.
* utils: drop ogCopyEfiBootLoader scriptAlejandro Sirgo Rica2024-03-263-11/+53
| | | | | | | | Implement a Python equivalent of ogCopyEfiBootLoader as the function copy_efi_bootloader. This function copies the contents of the folder of the EFI loader in the ESP into a ogBoot folder at the root of the partition target of an image creation. copy_efi_bootloader is a Windows only functionality.
* live: improve lzop and partclone error handlingAlejandro Sirgo Rica2024-03-261-27/+47
| | | | | | | | | | | Control non 0 returncode of the lzop and partclone subprocess in image creation and restoration because this means that either lzop or partclone has failed. The implementation must cover cases such as not enough storage space and log errors into /tmp/command.log and the log file of the client handling the request. Check the returncode of lzop and partclone subprocesses and log the stderr of the process reporting non zero returncode.
* live: improve logging in image_createAlejandro Sirgo Rica2024-03-261-2/+2
| | | | | | Log the whole context of the error when an exception happens. The previous exception handling was hidding important information about the cause of the error.
* utils: add enforce_gpt argument to get_efi_partition()Alejandro Sirgo Rica2024-03-262-5/+8
| | | | | | | 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.
* revert 7f18485: improve uefi detection mechanismAlejandro Sirgo Rica2024-03-262-13/+3
| | | | | | | | | | | Make is_uefi_supported() only check for /sys/firmware/efi as get_efi_partition() will detect a missing ESP or an invalid partition scheme. Stop using get_efi_partition() inside is_uefi_supported() as the former is eventually called in every UEFI related code. UEFI supports both MBR and GPT as partition schemes and this is a required change to handle the particular case of Windows not being able to boot UEFI from a MBR partition scheme.
* src: make exception messages more contextual and explicitAlejandro Sirgo Rica2024-03-217-9/+9
| | | | | | | Provide more information in exception messages as those are the source of the logging messages. Add information about paths, files or configuration related to the operation associated to the exception.
* src: change generic exception types to be more explicitAlejandro Sirgo Rica2024-03-214-13/+13
| | | | | | | | Replace exception types to be more explicit about the nature of the error. Improve the exception raising semantics by using the 'from' keyword, this wraps an older exception into a new one so it is still considered the same object.
* utils: fix string not being defined as f-strings when they shouldAlejandro Sirgo Rica2024-03-211-2/+2
| | | | | Add the string prefix f'' to string instances formated as f-string but not properly constructed to expand the inline variables.
* virtual: add missing check=True to subprocess.run()Alejandro Sirgo Rica2024-03-211-2/+2
| | | | | Raise exception from subprocess.run() calls as previous code is trying to capture these exceptions to handle de errors.
* src: centralize error logging into send_internal_server_errorAlejandro Sirgo Rica2024-03-217-81/+53
| | | | | | | | | | | | | | | | | | | | Use only the exception messages as the main resource for error messages. The previous error code had string duplication in the form of: logging.error('msg here') raise Exception('msg here') That approach also has the downside of having log duplication as it had the local logging.err() and a global logging.exception() inside send_internal_server_error capturing the exception message. The actual code only requires raising an exception with a proper error message. Improve exception messages to give more error context. Log every AssertionError as a backtrace. Use the 'raise Exception from e' syntax to modify the a previously raised exception 'e' into an exception with aditional context or different type. This also prevents the message that warns about newer exceptions being launch after an initial exception.
* ogclient: consolidate logging in client coreAlejandro Sirgo Rica2024-03-211-3/+2
| | | | | | | | | The main function must be able to handle the login of critical error in the main ogClient class instance. Add a try except block to the ogCLient run logic and move the relevant error logs into the except block. Delegate the error messages to the exception message. This is the first step towards error message deduplication.
* utils: implement BIOS boot for windowsAlejandro Sirgo Rica2024-03-212-30/+10
| | | | | | | | | | | | | | | | | | Create ogboot.me and ogboot.secondboot as empty files and ogboot.firstboot with the value "iniciado" in the root of the BIOS Windows system partition. The files must contain data for GRUB to be able to write content, therefore these are created containing 3072 null bytes. The Windows boot process is handled by the "pxe" profile. There the files ogboot.me, ogboot.firstboot and ogboot.secondboot are used as a state machine to chose between booting Windows and ogLive. The first Windows boot happens if ogboot.me and ogboot.firstboot are identical, then "iniciado" is written in ogboot.firstboot. We skip this stage as we create ogboot.firstboot with 'iniciado'. The second Windows boot occurs if ogboot.me and ogboot.secondboot are boot identical, then "iniciado" is written in ogboot.secondboot. After the Windows boot ogLive is booted.
* 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: implement BIOS boot for LinuxAlejandro Sirgo Rica2024-03-212-1/+70
| | | | | | | | | Create a bios.py file to hold all the BIOS specific functions. Implement the _boot_bios_linux in Python. The new boot process tries to find the vmlinuz and initrd binaries at the desired partition. Then it tries to load them with kexec with the proper Grub boot params. One step closer to the removal of the boot legacy script.
* live: check if cache partition is available before calling tiptorrentAlejandro Sirgo Rica2024-03-211-0/+4
| | | | | | The image restore command must check if the cache partition is available. Otherwise if the user forgets to create the cache tiptorrent fails.
* utils: handle exceptions caused by the hivex packageAlejandro Sirgo Rica2024-03-081-3/+6
| | | | | | The mage creation process was being interrupted by an error trying to read the Windows registry by the Hivex library. Now the exceptions are handled and an error is reported.
* utils: implement linux distro id detectionAlejandro Sirgo Rica2024-03-082-1/+27
| | | | | | | The OS probe logic must be able to check a distro programmatically, add get_linux_distro_id to return an id whitout versioning. Ensure the availability of 'ubuntu' when we need to ensure certain features are only used with a supported system.
* utils: move all boot from OS functionality into boot.pyAlejandro Sirgo Rica2024-03-082-25/+51
| | | | | | | | This change is a preparative for reimplementing the BIOS boot in order to deprecate the legacy script. All the codepaths to boot systems located at a partition are now called from the boot_os_at function enabling an easier structure for the incoming code.
* utils: improve uefi detection mechanismAlejandro Sirgo Rica2024-03-083-4/+14
| | | | | | | Checking the existence /sys/firmware/efi as it might appear sometimes in BIOS installs if the BIOS configuration is not proper. Checking for the EFI partition is the safest method to veryfy the install type.
* utils: handle missing file in getlinuxversion functionAlejandro Sirgo Rica2024-03-081-11/+15
| | | | | | The function getlinuxversion receives a path to the os-release file. The case of not being able to open it was not handled and thus causing an unwanted exception.
* 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.
* uefi: update EFIBOOTMGR_BIN to use /opt/opengnsys/sbin/efibootmgrv1.3.2-6OpenGnSys Support Team2024-03-051-1/+1
| | | | debian package with json support provides the binary through this path, update it.
* uefi: define EFIBOOTMGR_BIN to ease changing the efibootmgr binaryAlejandro Sirgo Rica2024-03-041-9/+11
| | | | | | The json functionality proposed upstream might be merged one day in efibootmgr so deploying a fork would not be needed anymore. This change aims to ease the migration once that day comes.
* live: drop IniciarSesion script when uefi booting into linuxAlejandro Sirgo Rica2024-03-041-6/+33
| | | | | | Replace IniciarSesion script in favor of native Python code when booting a UEFI system into Linux. This completes the implementation of booting into an OS on a UEFI compliant system.
