Default value for the %{with ...} when %bcond is not defined

[LecrisUT]

I want to define a logic like

%if %[ !%{without ctest} ]
  %ctest %*
%endif

where it should behave like:

• If spec file has a %bcond and no --with/--without are defined use the default value provided
• If spec file has a %bcond and --with/--without are provided, use the values overrided
• If no %bcond is defined, ignore any --with/--without values and use a default value

With the current implementation, the first 2 points are available out-of-the-box without even needing to negate the check. But the last point is the part that I am having trouble implementing because %{without ctest} will always evaluate to 0

rpm/macros.in

Lines 79 to 98 in 5f27041

	# Handle conditional builds.
	# (see 'conditionalbuilds' in the manual)
	#
	# Internally, the `--with foo` option defines the macro `_with_foo` and the
	# `--without foo` option defines the macro `_without_foo`.
	# Based on those and a default (used when neither is given), bcond macros
	# define the macro `with_foo`, which should later be checked:
	%bcond_override_default() %{expand:%%global bcond_override_default_%{1} %{2}}
	%__bcond_override_default() %{expand:%%["%%{?bcond_override_default_%{1}}"||"%%{2}"]}
	%bcond() %[ %{__bcond_override_default %{1} %{2}}\
	? "%{expand:%%{!?_without_%{1}:%%global with_%{1} 1}}"\
	: "%{expand:%%{?_with_%{1}:%%global with_%{1} 1}}"\
	]
	%bcond_with() %bcond %{1} 0
	%bcond_without() %bcond %{1} 1
	# Shorthands for %{defined with_...}:
	%with() %{expand:%%{?with_%{1}:1}%%{!?with_%{1}:0}}
	%without() %{expand:%%{?with_%{1}:0}%%{!?with_%{1}:1}}

Using %with_ctest or %_without_ctest directly was not fruitful either. One issue is that %with_* always has value 1, instead of using the default value and being overwritten by the --without flag, i.e. with the following :

%bcond()	%[ %{__bcond_override_default %{1} %{2}}\
-    ? "%{expand:%%{!?_without_%{1}:%%global with_%{1} 1}}"\
-    : "%{expand:%%{?_with_%{1}:%%global with_%{1} 1}}"\
+    ? %[  "%{expand:%%{?_without_%{1}}" ? "%{expand:%%global with_%{1} 0}" : "%{expand:%%global with_%{1} 1}" ]\
+    ? %[  "%{expand:%%{?_with_%{1}}" ? "%{expand:%%global with_%{1} 1}" : "%{expand:%%global with_%{1} 0}" ]\
]

I would be able to use %{?with_ctest:<my_default>}. There probably was some discussion on this design and I am curious if the current design is due to some backwards compatibility issue?

Alternatively, if whenever %bcond is called, it would save a %global bcond_defined_<name> than that could also be interrogated and move that check in the initial %if statement that I want to use.

It seems like %if %{undefined with_ctest} could work for your use case.

Build conditionals also support distro-wide overrides, which I initially thought was what you were looking for, except it's probably not relevant here. Anyway, here's the docs: https://rpm.org/docs/4.20.x/manual/conditionalbuilds.html#overriding-defaults
