# pylint setup, see https://www.pylint.org/.
#
# Disabled:
#   W0301 - Unnecessary semicolon.
#   W0511 - TODO/XXX/FIXME/+++.
#   W0603 - Using the global statement.
#   W0702 - No exception type(s) specified.
#   W0703 - Catch "Exception".
#   I0011 - Locally disabling XXXXX.
#   C0321 - More than one statement on a single line.
#   R0201 - Method could be a function.
#   C0326 - ????
#   W0123 - ????
#   C0330:bad-continuation - Wrong continued indentation (add X spaces).
#         * Triggering on perfectly legal comments in array initializers and stuff.
#   C0413:wrong-import-position - Import "YYYYY XXXXX" should be placed at the top of the module.
#         * False positives due to __copyright__, __version__, probably.
#   E0012:bad-option-value - Bad option value XXXXX.
#         * Newer pylint doesn't grok older warning disables in sources (e.g. W0142 in db.py). Wonderful!
#   I0012:locally-enabled - Locally enabling XXXXX.
#         * We temporarily disable stuff and then renabled it. Very tedious.
#   :nested-min-max - Buggy in 2.16.2 when mixing iterable and regular form, thus disabled.
#
# Note! Yes, --max-branchs is a typo, but not by me.
#
# Note! Users of older pylint release (< 1.0) needs to define
#       VBOX_WITH_PYLINT_PRE_V1_0 in LocalConfig because they changed the
#       output arguments in an backwards incompatible way and added more
#       attribute regex options.

# Code Signing.
#
# There are two signing modes; 'test' and 'release'.
#  - The 'test' mode is tailored local development, where typically test
#    certificates are involved. Only the bar minimum of files are signed and
#    nothing is timestamped (if we can control timestamping) in order to reduce
#    build time and to allow working offline.
#  - The 'release' mode is tailored for creating builds that are give to other
#    people, like the ones the build servers create.  As much as possible is
#    signed and timestamped.
#  - The 'adhoc' mode is specific to building on macOS and is similar to 'test'
#    mode but doesn't require any certificates but a host set up for development work.
#    Binaries are signed in adhoc mode and include required entitlements as appropriate
#    (something we would only do in the 'packing' target). This seem to be the only working
#    way with newer versions of macOS (tested with Ventura) with 'test' not working anymore.

  # so we can apply this to VBOX_RTSIGNTOOL as well - only that didn't work because
  # kmk tries to help windows caching images it executes.  So HACK ALERT on that.
  #
  # So, here is what we do.
  #   1. Sign $1 using the regular signing, probably dual signing it using local certs.
  #   2. Make temporary copy of $1 as $1.dual
  #   3. Do SHA-256 corp code signing of $1
  #   4. Add the SHA-256 signature from $1 to $1.dual using bldRTSignTool.

  #
  # @param 1  The file to sign.
  # @param 2  File description. Optional.
  # @param 3  Additional parameters. Optional.
  # @param 4  Set to 2 if the expression will be expanded twice before chopped into commands (for _CMDS).
  # @param 5  Disables dual & tripple signing if non-empty.

 ## and vboxguest respectively provide symbols that other modules use, we use
 ## the rule target (tst*.run) to save those symbols so that KBuild can do its
 ## checking.
 ##
 ## @param 1    Module name.
 ## @param 2    The test build which symvers we need (empty if none)
 ## @param 3    Save symvers if non-empty.
 ##
 ## @note Using the extra expansion to replace $(1), $(2) and $(3) before eval,

 # Hack for running on NT3x, NT4, W2K and XP w/o SP:
 #  1. Change OS and subsystem version in the image.
 #  2. NT 3.1 requires the IAT to be writable. To avoid making all of .rdata
 #     writable we use the undocumented -NoOptIData option to prevent .idata$*
 #     from being merged into .rdata.
 #  3. NT 3.1 doesn't support merging initialized and uninitialized section
 #     because it doesn't recognize Misc.VirtualSize.  So, we set the uncached
 #     flag (!K) on the .bss section make it incompatible with .data.
 #     VBOX_PE_SET_VERSION will clear the !K flag.  (Not needed in no-CRT mode,
 #     as the init code zeros uninitialized data there when running on NT 3.1.)
 # Similarly, for XP64 and 64-bit W2K3 we need to make sure the subsystem version
 # in the binaries are set to 5.2.  The Visual C++ 2019 linker defaults to 6.0.
