2022-06-21Add --trace-{match,execute} optionsBoris Kolpackov1-1/+95
These options can be used to understand which dependency chain causes matching or execution of a particular target.
2022-04-19Use target recipe for auxiliary data storage during match-applyBoris Kolpackov1-4/+5
In particular, we now have separate auxiliary data storage for inner and outer operations.
2022-04-19Skip find() inside target_set::insert*() if target is unlikely to be thereBoris Kolpackov1-1/+2
2022-04-19Cache "recipe is group_action" information, clear recipes after executionBoris Kolpackov1-6/+12
2022-04-18Avoid locking target set if in load phaseBoris Kolpackov1-16/+22
2022-04-08Optimize update_during_match()Boris Kolpackov1-7/+14
2022-04-08Add hint-less rule match pass for non-perform meta-operations as fallbackBoris Kolpackov1-116/+143
2022-04-07Rename {match,execute}() to *_sync(), add *_complete()Boris Kolpackov1-59/+35
In particular, the match() rename makes sure it doesn't clash with rule::match() which, after removal of the hint argument in simple_rule, has exactly the same signature, thus making it error-prone to calling recursively.
2022-04-06Add support for rule hintsBoris Kolpackov1-17/+13
A rule hint is a target attribute, for example: [rule_hint=cxx] exe{hello}: c{hello} Rule hints can be used to resolve ambiguity when multiple rules match the same target as well as to override an unambiguous match.
2022-03-10Add reverse_execute_prerequisites() variantBoris Kolpackov1-7/+102
2022-03-09Rename execute_wait() to execute()Boris Kolpackov1-1/+4
The old half-way semantics of execute() wasn't useful.
2022-03-09Parallel implementation of update_during_match_prerequisites()Boris Kolpackov1-22/+96
2022-03-08Improve performance of update during match for multiple targetsBoris Kolpackov1-0/+69
2022-03-02Add update operation-specific variable with unmatch|match additional valuesBoris Kolpackov1-3/+65
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.
2022-02-09Don't use fallback file_rule to clean real targetsBoris Kolpackov1-2/+14
2022-02-09Add perform_clean_group_extra()Boris Kolpackov1-123/+137

2022-01-21Add search_new() and search_new_locked() variants of search()Boris Kolpackov1-0/+22
2021-09-16Fix diagnostics corner case in perform_clean_extra()Boris Kolpackov1-5/+5
2021-08-05Avoid normalizing likely already normalized directories in search_existing()Boris Kolpackov1-1/+8
2021-06-08Implement ad hoc regex pattern rule supportBoris Kolpackov1-60/+102
An ad hoc pattern rule consists of a pattern that mimics a dependency declaration followed by one or more recipes. For example: exe{~'/(.*)/'}: cxx{~'/\1/'} {{ $cxx.path -o $path($>) $path($<[0]) }} If a pattern matches a dependency declaration of a target, then the recipe is used to perform the corresponding operation on this target. For example, the following dependency declaration matches the above pattern which means the rule's recipe will be used to update this target: exe{hello}: cxx{hello} While the following declarations do not match the above pattern: exe{hello}: c{hello} # Type mismatch. exe{hello}: cxx{howdy} # Name mismatch. On the left hand side of `:` in the pattern we can have a single target or an ad hoc target group. The single target or the first (primary) ad hoc group member must be a regex pattern (~). The rest of the ad hoc group members can be patterns or substitutions (^). For example: <exe{~'/(.*)/'} file{^'/\1.map/'}>: cxx{~'/\1/'} {{ $cxx.path -o $path($>[0]) "-Wl,-Map=$path($>[1])" $path($<[0]) }} On the left hand side of `:` in the pattern we have prerequisites which can be patterns, substitutions, or non-patterns. For example: <exe{~'/(.*)/'} file{^'/\1.map/'}>: cxx{~'/\1/'} hxx{^'/\1/'} hxx{common} {{ $cxx.path -o $path($>[0]) "-Wl,-Map=$path($>[1])" $path($<[0]) }} Substitutions on the left hand side of `:` and substitutions and non-patterns on the right hand side are added to the dependency declaration. For example, given the above rule and dependency declaration, the effective dependency is going to be: <exe{hello} file{hello.map>: cxx{hello} hxx{hello} hxx{common}

2020-03-17Rename all find*(variable) to lookup*(variable)Boris Kolpackov1-1/+1
Now we consistently use term "lookup" for variable value lookup. At some point we should also rename type lookup to binding and get rid of all the lookup_type aliases.
2020-03-10Force hard links inside backlinked DLL assembly directoryBoris Kolpackov1-3/+5
Windows does not allow the manifest file inside to be a symlink for some (probably security) reasons.
