Stages TWRP's GUI engine and standalone tooling as PawletOS-owned modules instead of a bootable/recovery fork, per the plugin-architecture finding in NOTES-ota-recovery-ab.md: stock recovery_main.cpp already dlopen()s librecovery_ui_ext.so and dlsym()s make_device() from it at runtime, so the UI layer doesn't require touching stock bootable/recovery at all. Confirmed via source grep that recovery.cpp/install.cpp have zero references into the partition manager/backup engine/GUI code and vice versa. recovery_ui/: TWRP's gui/, minuitwrp/, libpixelflinger/ (copied verbatim, GPL-3.0), plus a new device/ providing PawletTwrpUI (a ScreenRecoveryUI subclass) and make_device() — written from scratch against stock's RecoveryUI/ScreenRecoveryUI virtual-method contract, since TWRP's own fork never ships a make_device() (every real TWRP device provides its own, and no reference device tree was available to copy from). Top-level Android.bp defines librecovery_ui_pawlet_twrp, the module TARGET_RECOVERY_UI_LIB should point at. gui/Android.bp and minuitwrp/Android.bp had their include_dirs rewritten for the new paths. recovery_toolkit/: partition manager, backup engine (tar/digest/adbbu/apex), filesystem/format support (exfat/dosfstools/gpt/fuse/mtp/crypto), scripting (openrecoveryscript/orscmd/twrpinstall), shared helpers. Source only, no Android.bp yet for any of it. Known gap blocking recovery_ui from actually linking: gui/'s libguitwrp depends on libaosprecovery, built from recovery_toolkit/helpers/twrp.cpp via a Go Soong plugin (libaosprecovery_defaults.go) not yet ported. Neither repo has been build-tested — no local AOSP build environment available in this workspace. See each directory's README.md for a precise done/not-done breakdown.

/*
|
|
* Check collisions between options.
|
|
*
|
|
* The conflicts between options are described in ul_excl_t array. The
|
|
* array contains groups of mutually exclusive options. For example
|
|
*
|
|
* static const ul_excl_t excl[] = {
|
|
* { 'Z','b','c' }, // first group
|
|
* { 'b','x' }, // second group
|
|
* { 0 }
|
|
* };
|
|
*
|
|
* int excl_st[ARRAY_SIZE(excl)] = UL_EXCL_STATUS_INIT;
|
|
*
|
|
* while ((c = getopt_long(argc, argv, "Zbcx", longopts, NULL)) != -1) {
|
|
*
|
|
* err_exclusive_options(c, longopts, excl, excl_st);
|
|
*
|
|
* switch (c) {
|
|
* case 'Z':
|
|
* ....
|
|
* }
|
|
* }
|
|
*
|
|
* The array excl[] defines two groups of the mutually exclusive options. The
|
|
* option '-b' is in the both groups.
|
|
*
|
|
* Note that the options in the group have to be in ASCII order (ABC..abc..) and
|
|
* groups have to be also in ASCII order.
|
|
*
|
|
* The maximal number of the options in the group is 15 (size of the array is
|
|
* 16, last is zero).
|
|
*
|
|
* The current status of options is stored in excl_st array. The size of the array
|
|
* must be the same as number of the groups in the ul_excl_t array.
|
|
*
|
|
* If you're unsure then see sys-utils/mount.c or misc-utils/findmnt.c.
