2022-03-10Additions to Listmgr et alia (#1028)Werner Llácer
* Permit multiple default actions as a list * Define headers for list at ListManager and Menu * small corrections for default values * Make subvolume info work. The real marker that signifies that a mounted subvolume exist is the bracket notation nor the at sign
2022-02-08Change usage `lsblk` to `blkid` where possible. And general improvements to ↵Anton Hvornum
disk handling. (#949) * Renamed all_disks() to all_blockdevices() as it's technically a bit more correct. As it would return partitions as well. And it now distinguishes between BlockDevice() and Partition() when returning values. Also lsblk has been replaced with blkid and glob.glob() on /sys/class/block/ * Added handling of loop devices * Added device information enrichment * Removed old code * Updated the usage of blockdevice.info['type'] to 'DEVTYPE' as per returned by blkid instead of lsblk * Created a MapperDev() and DMCryptDev() 'disk' classes. This should help differentiate between BlockDevice(), Partition() and crypt-specific devices. Due to some new helper functions (mentioned later) BlockDevice().device_or_backfile has been simplified thanks to the information being pre-existing instead of having to call losetup. BlockDevice().mountpoint has been added as a dummy function. archinstall.enrich_blockdevice_information() has been added to enrich information extracted from blkid. archinstall.uevent() has been created to parse blkdid data when in -o export format, also eats up /sys/class/x/y/uevent data which is of the same format. all_blockdevices() now returns mapper devices found under /dev/mapper/ and properly returns the different types, not just BlockDevice() for everything. archinstall.get_parent_of_partition() has been added, which can translate /dev/sda1 to /dev/sda via strings by using /sys/class/block/ - note here tho that it has to be a blockdevice. Other parents won't return properly. archinstall.find_mountpoint() was created to be able to find mountpoints for a device, rather than the other way around which get_mount_info() handles. find_mountpoint() will convert /dev/sda1 -> /boot for instance, whereas get_mount_info('/boot') will convert /boot -> /dev/sda1. archinstall.get_partitions_in_use() will now properly traverse the entire structure, not just one level deep. This called for the creation of get_all_targets() which will take a dictionary structure and look for 'target': '/path' and return all '/path' values, recursively without being trapped in get_partitions_in_use() which has recursive targets. get_partitions_in_use() now returns a dictionary instead of a list, as it also returns the mountpoint and associated device. It will also prioritize MapperDev over DMCryptDev (as MapperDev is a child of DMCryptDev and can be resolved, other way around is 'trickier'). * Reverted Installer().partitions to return only the partitions. It's a slight speed defecit by not returning the mountpoints directly as {mntpoint: partition}, because the partition.mountpoint is a bit slow. But it avoids breaking legacy code :) * Fixed a few imports, and added MapperDev.filesystem * Fixed so that Installer().detect_encryption() uses the new separated logic of MapperDev/DMCryptDev/Partition * Fixing a translation issue on hostname * Added DMCryptDev.filesystem * Added back archinstall.all_disks() for legacy reasons. * Added a deprecation warning to archinstall.all_disks() * Added a enrichment check for dm-crypt specific devices, which in turn sets DMCRYPT_NAME on the device information, making it easier to detect and target DMCryptDev when needed. This should avoid issues with loopdevices being detected as DMCryptDev. Also some minor tweaks to variable names on unencrypted setups * Made debug output hidden without --verbose. Also added get_subvolume_info() which takes a path and returns any 'btrfs subvol show' information on the path * Partition().subvolumes has been added. Which generates an iterator over potential subvolumes based on mountpoint. Partition().mount_information is now a list of mount-destinations, as one partition should be allowed to be mounted to several places (more commonly used in btrfs subvolumes). BtrfsSubvolume() has been added as a 'device type', which should make it more easy to recognize a BtrfsSubvolume object right out of the gate. Only found from Partition().subvolumes currently. * Parameter fix for --verbose in log() * Made sure loopdev devices have a PATH key as well, to make dealing with them as blockdevice as seamless as possible. * Added backup information grabbing on uninitated devices * Tweaked backup option if losetup cannot find the blockdev * looks like losetup doesn't exit with a bad code even when it should. Raising ourselves when information is empty. * Fixed structure returned from get_blockdevice_uevent() * Made sure that fallback to blkid and loopdev info returns a PTTYPE (Partition Table Type) that is None, since we can't locate it yet (empty drive). But it's not False either, which is what logic after is looking for * Deprecated split_bind_name() and added more debugging * get_partitions_in_use() now only iterates over Partition() objects. And properly checks all mountpoints, not only the first. * Flipped SysCallError to show the last 500 bytes if data rather than the first, to catch the actual errors. * Removed anonymous parameters to all_blockdevices() * Added .mount_information to MapperDev * Added typing annotations * Partition().mountpoint is now a @property that will live-report the current mountpoint. * Removed the need for setting Partition().mountpoint = X when calling .mount() and .unmount(), as it's live-reported instead. * Added .subvolumes to MapperDev() * Added debug information * Muting F841 in helpers.py * Tweaked debug information in get_mount_info() * Minimized log output by moving Partition().mountpoint to DEBUG, as partitions are allowed to not be mounted * Simplified Installer().add_bootloader() to act as a router to the new split function, one for each bootloader type. This since flake8 complained about complexity and I agree that it became to wild.
2022-01-07Btrfs II (#838)Werner Llácer
* Btrfs with encrypted partitions. We have changed installer.mount_ordered_layout into a series of loops * open the encrypted devices * manage btrfs subvolumes * mount whatever * create kyefiles for encrypted volumes We have simplified the btrfs subvolume manager We merged the locale branch as it is needed here * We allow only the creation of keyfiles if the partition does not contain the root mount point. Also, adapt examples/only_hd to the new __init__.py Also, assorted flake8 warnings * Cleanup code * Naming schema for encrypted volumes revert global locale association (provisional) * We introduce the option of defining mount options in the partition dictionary. It has forced us to define two new entries in this dictionary: * format_options (formerly options) for mkfs options and * mount_options for mount -o ones. The different meaning of compress between partition and subvolumes is treated * Function lib/disk/btrfs.py mount_subvolume marked as deprecated Code cleanup. * format_options now filesystem.options * format_options now filesystem.format_options mount_options nof filesystem.mount_options * flake8 uncovered a slip in the code
2022-01-06Added type annotations to all functions (#845)Anton Hvornum
* Added type annotations for 1/5 of the files. There's bound to be some issues with type miss-match, will sort that out later. * Added type hints for 4/5 of the code * Added type hints for 4.7/5 of the code * Added type hints for 5/5 of the code base * Split the linters into individual files This should help with more clearly show which runner is breaking since they don't share a single common name any longer. Also moved mypy settings into pyproject.toml * Fixed some of the last flake8 issues * Missing parameter * Fixed invalid lookahead types * __future__ had to be at the top * Fixed last flake8 issues
2021-12-31Btrfs2 (#787)Werner Llácer
* All the changes needed to make btrfs subvolumes work. It boils down to two points; the handling of the addressing of subvolumes re. physical partitions, and the small changes at the bootloader level * We added a new script only_hd for testing purposes. It only handles hadrd drive management * restoring an escape hatch during subvolume processing * hipercommented manage_btrfs_subvolumes * Ready to be able to select and process options in subvolume mounting * Separte nodatacow processing * Solving a flake8 complain * Use of bind names @ get_filesystem_type * compress mount option bypass * Preparations for encryption handling * Compatibility to master version re. encrypted btrfs volumes * Now we can create subvolumes and mountpoints inside an encrypted btrfs partition * changes for entries file generation with systemd-bootctl * flake8 corrections plus some comments Co-authored-by: Anton Hvornum <anton@hvornum.se>
2021-11-05Cleaned up all flake8 issues/warnings. Did some code cleaning as well, ↵Anton Hvornum
mostly how we called things in guided.py but also some SysCommand calls

2021-10-27Finalized the create_subvolume and mount_subvolume functions. Remaining is ↵Anton Hvornum
to call these functions during the disk setup process to create the subvolumes and mount them in place, rather than doing the normal steps.
2021-10-22Restructured disk.py into lib/disk/<splits>.py instead. Shouldn't be any ↵Anton Hvornum
broken links as we expose all the functions through __init__.py - but you never know so I'll keep an eye for issues with this.
