[SDK][CMLIB] Declare some BootType and BootRecover identifiers & Miscellaneous Stuff
=== DOCUMENTATION REMARKS ===

HBOOT_TYPE_REGULAR and HBOOT_TYPE_SELF_HEAL are boot type values set up by the CMLIB library (for the BootType field respectively). HBOOT_TYPE_REGULAR indicates a normal system boot whereas HBOOT_TYPE_SELF_HEAL indicates the system boot is assisted within self healing mode.

Whether the former or the latter value is set it's governed by both the kernel and the bootloader. The bootloader and the kernel negotiate together to determine if any of the registry properties (the hive, the base block, the registry base, etc) are so severed from corruption or not. In extreme cases where
registry healing is possible, the specific base block of the damaged hive will have its flags marked with HBOOT_TYPE_SELF_HEAL. At this point the boot phase procedure is orchestrated since the boot phase no longer goes on the default path but it's assisted, as I have already said above.

HBOOT_NO_BOOT_RECOVER, HBOOT_BOOT_RECOVERED_BY_HIVE_LOG and HBOOT_BOOT_RECOVERED_BY_ALTERNATE_HIVE on the other hand are identifiers for the BootRecover field of the BASE_BLOCK header structure. These are used exclusively by FreeLdr to tell the kernel if the bootloader recovered the SYSTEM hive or not. In case where the bootloader did recover the SYSTEM hive,
the kernel will perform a flush request on the dirty data down to disk. The (almost) worse case FreeLdr could not repair the main hive by applying log data, it will load the alternate mirror version of the hive.

In addition to that, declare other miscellaneous CMLIB identifiers for log transaction writes purposes.

[SDK:CMLIB][FREELDR:NTLDR] Revert commit 168fea0ee and provide a better fix. Addendum to 93d8a1b7b.
Correct fix was to fix the HCELL_INDEX <-> HKEY conversions, much like
is being done with UlongToHandle / HandleToUlong.

The on-disk/in-memory hive file structures are platform-independent:
their layout must not depend on whether code is compiled in 32 or 64
bits.

[CMLIB] Minor code style changes only: Use slightly more explicit signature #define names so that we know to which hive structure they correspond. 2019-02-17 01:21:36 +01:00
Colin Finck c2c66aff7d Git conversion: Make reactos the root directory, move rosapps, rostests, wallpapers into modules, and delete rossubsys. 2017-10-03 07:45:34 +00:00
