2020-05-04rename binary_loopback_cfg to binary_grub_cfgLyndon Brown
when loopback support was introduced, it initially duplicated the code for generating a grub2 config, before the duplicated code was removed from the grub-pc script, effectively thus moving grub config generation to the loopback feature script. grub-efi support was added after this. this results in a misleading filename, since the `binary_loopback_cfg` script is essential for use of grub-pc|grub-efi, and actually only has a single line of code on top that's needed for adding actual loopback support on top. (when grub-pc and grub-efi are not used, the entire script is still needed for loopback support to work). so here we rename it to make better sense, and correct/clarify bits of documentation.

2020-05-04config: improve BIOS/EFI bootloader selection handlingLyndon Brown
the design choice from when EFI support was introduced was to change `--bootloader` to `--bootloaders`, with users specifying their selection of BIOS and EFI bootloaders together. at this time there were not even any decent validation checks being performed, and invalid combinations could cause some chaos. since then proper validation was put in place, including checking that only a single instance of each of BIOS and EFI bootloaders exists in the selection. here we tweak things such that we stick with the same option, but we split the selection up such that we store the BIOS and EFI selections separately within the saved config file, and offer it up to scripts to help simplify those scripts. we must however retain support for splitting from the combined option, both because we still use it in the combined option, and for backwards compatibility with older saved configs.

2020-05-04fully validate BIOS/EFI bootloader combinationsLyndon Brown
thus far, config bootloader validation only did the basic check that each bootloader specified was a known and supported bootloader, it did not check combinations. it now checks combinations, and strips out the previous "bootloader role" stuff. the no-bootloaders warning is duplicated, covering two slightly different situations (empty string, and whitespace string). this is anticipated to be just temporary, with this just being the first step in better handling bootloader selections.

2020-04-23config: s/LIVE_IMAGE_TYPE/LB_IMAGE_TYPE/Lyndon Brown
no backwards compatibility hack for reading the old var from existing saved config used because this was previously stored in the alternate format config/build file. Gbp-Dch: Short
2020-04-23move grub-pc specific code to actual grub-pc scriptLyndon Brown
the grub-pc image creation code has no business being in binary_iso, it should be in binary_grub-pc. it should be noted that the binary_iso script did not even have the necessary package check for grub-mkimage, while binary_grub-pc did have it, pointlessly. Gbp-Dch: Short

- add a validation check where an error will be printed - replace the check done in the grub scripts with one that simple exits if executed bypassing the validation check Gbp-Dch: Short
2020-04-23--binary-images can support only a single typeLyndon Brown
whilst some parts of the codebase were set up to work with multiple types specified, others did not work with it and would not necessarily be easy to adjust. this thus makes some tweaks to adjust things accordingly. - option renamed to singular form (maintaining backwards compatibility) - a validation check has been added - unnecessary glob style type references fixed - checks with In_list changed to a direct singular comparison - typo of type "netboot" written as just "net" fixed (though unreachable so of no consequence; really the code could be removed but it's trivial) Gbp-Dch: Short
2020-03-17stagefiles: s/Require_stagefile/Require_stagefiles/Lyndon Brown
this function takes one or more required stage fileS _plural_, and exits if any are missing (or at least it does now after the refactor). let's rename it to make things more clear Gbp-Dch: Short
2020-03-17stagefiles: further robustify with auto filenamesLyndon Brown
as suggested by Raphaël rather than have fixed stagefile filename strings at all in the scripts, use `$(basename $0)` to use the name of the script (which is the same for almost all cases anyway, and the stage files are supposed to be almost exclusively unique per-script). we can thus simplify things by determining the filename for most use cases within the functions themselves. this does change the file used by a couple of scripts, affecting backwards compatibility of executing live-build upon an existing partially or fully completed build: - binary_grub-pc used "binary_grub" - chroot_includes used "includes.chroot" care had to be taken for the following cases: - there are some cases like bootstrap_cache, source_debian and bootstrap_debootstrap which are dealing with more than one file, and/or otherwise a filename that is not specific to the script itself exactly, or should not be based upon its name. - some cases like chroot_cache, bootstrap_cache and chroot_install-packages need to append something to the end of the name depending upon which pass/action mode the script is being executed with. - furthermore in the bootstrap_cache case one of the filenames is used within the bootstrap_debootstrap and thus needs very careful handling to be certain that a change in filename of bootstrap_cache does not break bootstrap_debootstrap. Gbp-Dch: Short
2020-03-17stagefiles: simplify & robustifyLyndon Brown
- avoid all need to pass ".build/" path in stage file names into the functions - add a helper to remove a stage file (required to complete the above properly) - avoid duplicating filenames within scripts which makes them prone to mistakes (some instances of which I've actually encountered and had to fix) Gbp-Dch: Short

2020-03-13locks: tidy lock acquisitionjnqnfe
Combine the check+create done in each script. (The original functions are still callable as before, but a new combined `Aquire_lockfile` function can be called instead, as now used). Note, a further simplification could be done in removing the passing of the lock filename in as a parameter since every use of the functions is with ".lock". The lock functions already have a fallback to ".build/lock" though. Checking the history, the fallback used to be for a system wide lock, which was then replaced with this config-tree specific one. As long as that is not used implicitly by 3rd-party hooks then surely we are free to change the fallback to ".lock" and further remove passing in a name as a param...? history: db5d2b0dcdae96e712661605e17bc9875e224f9f 0aa8289a3773fd8a3885090b72622c2f95ab099c Gbp-Dch: Short Closes: #952918
2020-03-13strip useless multi-arch separate directory stuffjnqnfe
(part of never completed side-by-side multi archi support) Several scripts make a call to a function called Check_multiarchitectures, the purpose of which is to adjust the target directory that certain 'live' and 'install' files are located in. The idea is that a script sets up 'DESTDIR', 'DESTDIR_LIVE' and 'DESTDIR_INSTALL' as appropriate and then the script appends a suitable arch dependant postfix to the directory name, depending upon the arch currently being targetted. This would allow the script to be run multiple times, each for a different architecture. This is a part of an implementation of allowing multiple architectures to sit side by side within the same live image, selectable from the bootloader menus. (As opposed to multiple architectures mixed within the same userland). This is evidently the case both from the fact that: 1) The arch specific postfix chosen in that function depends on a var called LB_CURRENT_ARCHITECTURE, which is never set. In fact going back through the git history to the introduction of the function in 0d5ff4ca7596790f853cf637e0fe225cad810a76, the var (even considering var name changes) has never been set by anything. So effectively the call to the function has been entirely redundant all this time. 2) The major build stages do not perform multiple executions of substages per arch. Thus from this perspective it seems that the support was never fully implemented. 3) If any doubt remained, there is an old branch called 'tmp-multiarch' which has a couple of commits making progress with completing support, such as implementing the above missing pieces. The above mentioned branch is 10 years old and can be considered abandoned. It is not clear whether the original author ever intended to complete and merge this; nor is it at all clear at what stage of completion it was at. At any rate, imo it is not at all particularly useful to have extra code and complexity in order to be able to cram multiple environments side by side in one image, not when CDs/DVDs and even to some extent USB pen drives are so cheap. And who really needs more than one environment so desperately on just one such medium. If this was not enough to justify removal, then there is also the fact that the support that was implemented has become completely broken over the years with scripts diverging in terms of the variable names the function modifies such that they are incompatible with it. A quick assessment of the state of this latter aspect: good: - grub-legacy uses the correct var names so is fine - memtest similarly good - installer_debian-installer looks okay questionable: - binary_linux-image uses the correct vars but might not select the right kernel and initrd files to copy (seems to copy all) bad: - grub-pc is making a redundant call, after functionality was moved to the loopback script - loopback is using the wrong vars (INITFS instead of DESTDIR + DESTDIR_INSTALL + DESTDIR_LIVE), plus is doing its own amd64+i686 thing anyway, so the function call would achieve nothing anyway. - syslinux is also using the wrong var names so would not work with it and is not even making the necessary function call. Also the install paths are fixed in the hard coded cfg files anyway so this would need addressing with placeholders and sed replacement, but then it is not entirely clear how things should work with respect to install entries and multi-arch anyway, are we having multiple copies of the installer, one for each target arch and then multiple copies of the install menus, perhaps under different submenus? So, this removes the artefacts of this never completed feature. Gbp-Dch: Short
2020-03-12grub: fix incorrect error handlingLyndon Brown
2020-03-11amend copyright & licensing blocksLyndon Brown
Current versions of the project files are built upon versions published and licensed by Daniel Baumann, but are modified copies of those files and thus need to be marked as such per licensing requirements (afaik he did not pass along ownership / licensing rights to anyone when he left the project). We should also be careful to not be misrepresenting such modified copies as being attributed to Daniel. Adding a new copyright line referring to "The Debian Live team" should suffice for this. The authorship block in man pages has also similarly been updated. Notes: - tweaked a copy of daniel copyright lines stating 2014 instead of 2015. both of these cases were in files that i had personally introduced in some of my past merged commits that moved some code around. i don't know why they stated 2014. - binary_onie was introduced in 2018, so that has a 2018 date instead of 2016 unlike the rest. - 'efi-image' is a 3rd-party (Canonical Ltd) work that we bundle, but it has been modified by 674794a8f4d61a729d2dbd6d99385d2826138694 and 36a3ba76347ef72df1c316312ed3a26aa4b0c816 so I similarly added a debian live copyright line. - 'grub-cpmodules' is similar. it was only changed by the indentation fix of 36a3ba76347ef72df1c316312ed3a26aa4b0c816 but modification is modification, and this does help cover any possible future changes that might be made.

2016-12-02Drop useless code in binary_grub-pcRaphaël Hertzog
2016-07-31binary_loopback_cfg now renders grub.cfg by default.Adrian Gibanel Lopez
The binary parts of grub-pc are left for the original binary_grub-pc. As a consequence both /boot/grub/grub.cfg and /boot/grub/loopback.cfg files will be present in any Debian Live CD. This might be useful to be reused from binary_grub-* bootloaders.
2016-07-31Added new multi bootloader helper functionsAdrian Gibanel Lopez
* Added: functions/bootloaders.sh . This file adds bootloader functions that are heavily used in efi scenarios where a bootloader can act as a first or an extra bootloader. Since the introduction of the new switch: --bootloaders you can setup it like this: --bootloaders=syslinux,grub-efi . This means that syslinux is the first bootloader and grub-efi is the extra bootloader. * Added new bootloader functions: Check_Non_First_Bootloader and Check_Non_Extra_Bootloader. These functions let each one of the bootloaders abort the build because they cannot perform a role either as a first bootloader or as an extra bootloader. * Added bootloader functions: Check_First_Bootloader_Role, Check_Extra_Bootloader_Role and Check_Any_Bootloader_Role These functions let bootloaders to force their default role in a single line. At the same time many binary bootloaders were rewritten to make use of the new bootloader role functions explained above. These roles were enforced: binary_grub-legacy : First bootloader binary_grub-pc : Either first or extra bootloader binary_syslinux : Either first or extra bootloader If a bootloader is tried to be used in a role that it's not meant to be used then the build fails because that might lead to a non-bootable system.
2015-08-29Multi bootloader supportAdrian Gibanel Lopez
Note: OLDIFS use makes IFS to be reset to "" instead to it being unset. Either we need to detect if old IFS was unset to unset it or we need a proper way of setting it as a local variable. Even more IFS it's not currently used in Check_package (which it's called from: binary_hdd). we should have a clean way of resetting/unsetting IFS when calling Check_package. The other approach it's to explicitly define IFS with its default value in the places inside live-build code where we implicitly suppose that it's going to have its default value.
