2022-09-21	Fix regression in dynamic dependency extraction, byproduct mode	Boris Kolpackov	1	-2/+3

2022-06-24	Allow ad hoc rules not to list targets that are updated during match	Boris Kolpackov	1	-2/+5
	For example, this allows a Qt moc rule not to list generated headers from libQtCore since they are pre-generated by the library.
2022-03-02	Add update operation-specific variable with unmatch\|match additional values	Boris Kolpackov	1	-3/+6
	Note that the unmatch (match but do not update) and match (update during match) values are only supported by certain rules (and potentially only for certain prerequisite types). Additionally: - All operation-specific variables are now checked for false as an override for the prerequisite-specific include value. In particular, this can now be used to disable a prerequisite for update, for example: ./: exe{test}: update = false - The cc::link_rule now supports the update=match value for headers and ad hoc prerequisites. In particular, this can be used to make sure all the library headers are updated before matching any of its (or dependent's) object files.
2022-02-09	Add dyndep_rule::inject_group_member()	Boris Kolpackov	1	-1/+24

2022-01-06	Add depdb-dyndep --update-{include,exclude} options	Boris Kolpackov	1	-2/+6
	These options specify prerequisite targets/patterns to include/exclude (from the static prerequisite set) for update during match as part of dynamic dependency extraction (those excluded will be updated during execute). For example: depdb dyndep ... --update-exclude libue{hello-meta} ... depdb dyndep ... --update-exclude libue{} ... depdb dyndep ... --update-include $moc --update-include hxx{} ... The order in which these options are specified is significant with the first target/pattern that matches determining the result. If only the --update-include options are specified, then only the explicitly included prerequisites will be updated. Otherwise, all prerequisites that are not explicitly excluded will be updated. If none of these options is specified, then all the static prerequisites are updated during match. Note also that these options do not apply to ad hoc prerequisites which are always updated during match.
2021-12-16	Don't consider implied existing targets in dyndep logic	Boris Kolpackov	1	-1/+3
	While considering implied targets should be harmless, the result is racy.
2021-11-30	Add support for dynamic dependencies as byproduct of script body	Boris Kolpackov	1	-15/+61
	Specifically, the `depdb dyndep` builtin now has the --byproduct option (which must come first). In this mode only the --file input is supported. For example: obje{hello.o}: cxx{hello} {{ o = $path($>) t = $(o).t depdb dyndep --byproduct --what=header --default-type=h --file $t diag c++ ($<[0]) $cxx.path $cxx.poptions $cc.poptions $cc.coptions $cxx.coptions $cxx.mode -o $o -MD -MF $t -c $path($<[0]) }} Naturally, this mode does not support dynamic auto-generated prerequisites. If present, such prerequisites must be specified statically in the buildfile. Note also that the --default-prereq-type option has been rename to --default-type.
2021-11-23	Add support for dynamic dependencies in ad hoc Buildscript recipes	Boris Kolpackov	1	-0/+168
	Specifically, add the new `depdb dyndep` builtin that can be used to extract dynamic dependencies from a program run or a file. For example: obje{hello.o}: cxx{hello} {{ s = $path($<[0]) depdb dyndep $cxx.poptions $cc.poptions --what=header --default-prereq-type=h -- $cxx.path $cxx.poptions $cc.poptions $cxx.mode -M -MG $s diag c++ ($<[0]) o = $path($>) $cxx.path $cxx.poptions $cc.poptions $cc.coptions $cxx.coptions $cxx.mode -o $o -c $s }} Currently only the `make` dependency format is supported.
