* live: fix ogChangeRepo invocationJose M. Guisado2023-03-271-1/+1
| | | | | | | | | | | | | Add missing samba credentials parameter in ogChangeRepo invocation. Credentials are loaded from ogClient config file. Any production deployment should use its own samba user and password. ogChangeRepo fails when using default samba credentials in a production environment. Fixes: a1edbe904b30 ("legacy: rewrite ogChangeRepo") Fixes: 3703fd60634f ("live: support native unicast cache image restore")
* live: fix unicast cache error log messageJose M. Guisado2023-03-271-1/+1
| | | | | | | | | Removes undefined 'repo' variable from error logging message. This caused the traceback to be polluted with an unhelpful message about this variable being undefined. Fixes: 3703fd606 ("live: support native unicast cache image restore")
* legacy: rewrite ogChangeRepoJose M. Guisado2023-03-021-1/+1
| | | | | | | | | | | | | | | | 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.
* live: rewrite setup operationv1.2.5Jose M. Guisado2023-02-091-16/+44
| | | | | | | | | | | | | | | | Rewrites the setup operation using python-libfdisk module instead of an external bash script. Consolidating the operation into Python's code, limiting external subprocesses to well known programs and small concrete tasks that are difficult to fully integrate into Python. Use parttypes.py to fetch partition types from python-libfdisk module. Use fs.py to create any specified supported filesystem. OpenGnsys cache partitions are created labelling the partition as "CACHE". Stops setting non-standard MBR hexcode (0xca) to the cache partition in addition to the filesystem label. Any partition specified as type EMPTY will be ignored.
* live: clear ogbrowser log before image_createv1.2.4Jose M. Guisado2022-12-051-0/+1
| | | | | Remove any previous unrelated log message shown in the "real time log" html page before executing this command.
* live: clear ogbrowser logs before image_restoreJose M. Guisado2022-12-011-1/+7
| | | | | | | | | | Clears content of blue text areas in the real time log view before executing a restore image operation. Adds private function _ogbrowser_clear_logs, this function writes to a couple of text files present in the ogLive environment. The contents of this file are printed out to the blue text areas in the "real time log" view.
* live: improve error pathsv1.2.3Jose M. Guisado2022-11-171-3/+13
| | | | | | | | | | | | | 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.
* live: support native unicast cache image restoreJose M. Guisado2022-11-021-3/+32
| | | | | | | | | | | | | UNICAST-CACHE consist of: 1. Checking if the target image is already present at the opengnsys cache partition. If so, check for integrity (local and remote checksum). If the image is not present in the cache partition, download the target image into it. 2. Restore the image from cache partition. This commit add support for this operation natively from ogClient Python's code.
* live: don't use python open() when reading imageJose M. Guisado2022-09-231-5/+3
| | | | | | | | Specifies the image path in the lzop subprocess string. It might be interesting to study efficient mechanisms to read large binary files in python before using open() with default parameters for buffered binary reading.
* live: rewrite image_restoreJose M. Guisado2022-09-141-15/+50
| | | | | | | | 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".
* image_restore: fix ogCopyEfiBootLoaderJose M. Guisado2022-09-141-1/+1
| | | | | | | | | 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. Guisado2022-09-141-2/+1
| | | | | | | | | | 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/+1
| | | | | | | | | | | | | | 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. Guisado2022-08-241-25/+80
| | | | | | | | | | | 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.
* refresh: use '0' if disk has no labelJose M. Guisado2022-08-221-1/+4
| | | | | | | | If disk has no label, python-libfdisk returns None when accessing cxt.label Fixes bug when running refresh on computers whose disk/s have no label.
* live: enable details for libfdisk context objectv1.2.1Jose M. Guisado2022-06-081-1/+1
| | | | | | | Enables details in libfidsk context constructor call. Ensures size are displayed as bytes (and not as a human readable string). Avoids further arithmetical errors (e.g: converting from bytes to KB)
* live: remove unused parseGetConf functionJose M. Guisado2022-06-081-27/+0
| | | | | | parseGetConf was necessary for parsing output from OpenGnsys script "getConfiguration", which has been replaced since commit 1ab981a539f3 ("live: replace getConfiguration with refresh")
* src: improve loggingJose M. Guisado2022-06-081-1/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
* live: replace getConfiguration with refreshJose M. Guisado2022-06-011-10/+4
| | | | | | | Old refresh was a wrapper around getConfiguration bash script. New refresh operation does what getConfiguration used to do externally. See commit 097769b971f64f93004a87393721a289fe3db13f.
* live: assume VFAT is always FAT32Javier Sánchez Parra2022-06-011-0/+3
| | | | | fdisk reports VFAT, however, OpenGnsys does not have such entry in the filesystem table. Add an alias to FAT32 as a workaround.
* live: generate cache.txt file in refreshJose M. Guisado2022-06-011-0/+2
| | | | | | | | | | | | | 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.
* Add link speed to refresh responseJavier Sánchez Parra2022-05-091-1/+4
| | | | | Probe response already has client's link speed, but this API is deprecated.
* live: detect cache partitions in new refreshJose M. Guisado2022-04-281-3/+14
| | | | | | | Detects OpenGnsys cache partition when building the partition setup of a live system. OpenGnsys labels a Linux/ext4 partition as "CACHE".
* live: get partition number using partno attributeJose M. Guisado2022-04-271-6/+7
| | | | | | | | | | | | Removes a workaround enumaration of the partitions of a given libfdisk context. Use Partition class partno attribute. This enables detecting non contiguous partitions, like: /dev/sda /dev/sda1 /dev/sda2 /dev/sda4
* live: use utils.py and fdisk in refresh operationJose M. Guisado2022-04-211-12/+71
| | | | | | | | | | | | Use python binding for libfdisk to retrieve disk label and partition information [1]. Use utils.py for the rest of the process. This change aims to drop dependency with external script 'getConfiguration' from the OpenGnsys scripting ecosystem. Keeps the same json payload structure for the refresh response. [1] https://git.48k.eu/python-libfdisk/
* live: use utils.py for probe operationJose M. Guisado2022-04-211-22/+4
| | | | Import ethtool function from utils.py
* #1037 Add disk typeJavier Sánchez Parra2021-05-261-0/+1
| | | | | | | Add ogClient support to receive, parse and send disk type data from the cloning engine when refreshing disks configuration. See also commits with #1037 in ogServer and WebConsole repo.
* ogClient is AGPLv3+OpenGnSys Support Team2021-05-141-3/+3
| | | | Update license header in files.
* #995 Add link speed in probe responsesJose M. Guisado2021-05-041-0/+29
| | | | | | | | Separates probe method into separate ogclient modes (virtual, vdi) so future supported OS can easily have a tailored probe responses. Link speed is retrieved using a minimal ethtool command sent using fcntl module from python.
* #1000 live: check imageCreate for non-zero return codev1.2.0Jose M. Guisado2020-12-151-0/+3
| | | | | | | | | When running image_create operation an underlying script "imageCreate" is called using the subprocess python module. This script may fail, for example if the repository in which the image is to be stored has no sufficent capacity. Check for non-zero when the imageCreate process has finished.
* Rename 'linux' folder and operations to 'live'Jose M. Guisado2020-12-031-0/+275
ogLive related operations are named inside a 'Linux' folder, also its python class is named OgLinuxOperations. Rename every 'linux' occurrence with live to further clarify this folder and operations. - OgLinuxOperations -> OgLiveOperations - src/linux/ -> src/live/ Fixes: 1377acee ('Rename 'linux' mode to 'live' mode')
