2023-05-29Explicit group: syntax parsingBoris Kolpackov1-0/+1
2023-05-09Add --load-only option in addition to --match-onlyBoris Kolpackov1-2/+2
This option has the effect of loading all the subdirectory buildfiles that are not explicitly included.
2023-04-19Fix several issues in build system module importation logicmodule-importBoris Kolpackov1-1/+1
2023-04-13Various minor generalizations for in-process configure support in bpkgBoris Kolpackov1-208/+245
2023-04-05Allow creating context with bare minimum of initializationsBoris Kolpackov1-15/+53
This is used by bpkg to detect forwarded configurations without incurring the full context creation overhead.
2023-03-01Add support for installation manifestBoris Kolpackov1-0/+3
2022-12-19Disable `)` escaping in buildspec, command line variable overridesBoris Kolpackov1-5/+5
Similar to line continuations, that would make directory paths on Windows unusable, for example: b info(C:\myproj\) Note that while this is less of a problem in command line variable overrides, we disable it there for consistency.
2022-12-19Disable line continuation in buildspec, command line variable overridesBoris Kolpackov1-4/+5
Line continuations would make directory paths on Windows unusable, for example: b C:\myproj\
2022-12-19Restore newline escaping (line continuations) in double-quoted stringsBoris Kolpackov1-3/+4
Also make effective escaping in buildspec and command line variable overrides consistent with double-quoted strings.
2022-12-08Add --[no]diag-color options (infrastructure only)Boris Kolpackov1-3/+15
2022-11-30Reserve targets, variables to avoid rehashingBoris Kolpackov1-0/+15
2022-11-29Fix backlink logic for target groupsBoris Kolpackov1-3/+5
We used to backlink ad hoc group members both via the group and as individual members. And for explicit groups it was done only via individual members, which means it only works correctly if every member is individually updated. Now both types of groups are backlinked from the group target.
2022-11-08More work on child process diagnostics bufferingBoris Kolpackov1-1/+2
2022-10-28Add ability to disable diagnostics buffering (--no-diag-buffer)Boris Kolpackov1-0/+2
2022-10-19Add support for post hoc prerequisitesBoris Kolpackov1-0/+4
Unlike normal and ad hoc prerequisites, a post hoc prerequisite is built after the target, not before. It may also form a dependency cycle together with normal/ad hoc prerequisites. In other words, all this form of dependency guarantees is that a post hoc prerequisite will be built if its dependent target is built. See the NEWS file for details and an example.
2022-10-13Switch to public/private variables modelBoris Kolpackov1-23/+16
Now unqualified variables are project-private and can be typified.
2022-10-11Factor variable patterns out of variable_pool into separate variable_patternsBoris Kolpackov1-9/+15
We have patterns only for the public variables pool.
2022-10-10Preparatory work for public/private variable distinctionBoris Kolpackov1-2/+6
We still always use the public var_pool from context but where required, all access now goes through scope::var_pool().
2022-05-23Cache build.host value in contextBoris Kolpackov1-2/+3
2022-04-15Omit unnecessary clearing of cached base_scope valuesBoris Kolpackov1-0/+6
2022-04-13Cache target base scope lookupsBoris Kolpackov1-4/+30
2022-04-08Fix race in phase lock contention countingBoris Kolpackov1-6/+6
2022-04-08Add phase switch contention to build statisticsBoris Kolpackov1-0/+8
2022-04-06Add support for rule hintsBoris Kolpackov1-6/+5
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.
2022-03-07Fix operation-specific variables logic for inner/outer operationsBoris Kolpackov1-8/+18
2022-03-02Add update operation-specific variable with unmatch|match additional valuesBoris Kolpackov1-4/+20
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.
2022-02-17Add build.mode global variableBoris Kolpackov1-0/+12
This value signals any special mode the build system may be running in. The two core modes are `no-external-modules` (bootstrapping of external modules is disabled) and `normal` (normal build system execution). Build system drivers may invent additional modes (for example, the bpkg `skeleton` mode that is used to evaluate depends clauses).
2022-02-14Factor reusable code to contex::enter_project_overrides()Boris Kolpackov1-0/+61
2021-10-21Add build.progress global variable with --[no-]progress option valueBoris Kolpackov1-0/+11
2021-09-28Adapt to libbutl headers extension change from .mxx to .hxxKaren Arutyunov1-1/+1
2021-06-08Get rid of special *{} wildcard target type notation in target type/patternsBoris Kolpackov1-9/+15
Explicit target{} should be used instead. Also, in this context, absent target type is now treated as file{} rather than target{}, for consistency with all other cases.
2021-05-12Deal with helper thread starvation during phase switchingBoris Kolpackov1-19/+41
The implemented solution entails shadowing old phase queues so that helpers don't pick up old phase tasks and boosting the max_threads count so that we can create more helpers if all the existing ones are stuck in the old phase.
2021-05-12Keep phase locked while working own queueBoris Kolpackov1-11/+19
2021-05-05Deactivate when blocked on load phase mutexBoris Kolpackov1-2/+12
This turned out to be important when building in multiple contexts that share the scheduler (e.g., main and module/recipe build context). In this case we need an accurate active thread count in order to decide when to start an extra helper thread past max_active.
2021-03-19Redo entering of src directories into scope_mapBoris Kolpackov1-3/+3
2021-03-16Define intermediate build results file cache interfaceBoris Kolpackov1-0/+2

2021-01-15Disable questionable unused functionalityBoris Kolpackov1-0/+2
2020-09-22Add ability to skip external modules during bootstrap (--no-external-modules)Boris Kolpackov1-0/+2
2020-06-29Add legal{} target type and config.install.legal variableBoris Kolpackov1-0/+1
This allows separation of legal files (LICENSE, AUTHORS, etc) from other documentation. For example: ./: ... doc{README} legal{LICENSE} $ b install ... config.install.legal=/usr/share/licenses/hello/
2020-06-01Extend target metadata to include variable prefix, stable nameBoris Kolpackov1-2/+2
2020-05-27Initial support for ad hoc recipes (still work in progress)Boris Kolpackov1-1/+11
2020-04-27Rework tool importation along with cli moduleBoris Kolpackov1-1/+4
Specifically, now config.<tool> (like config.cli) is handled by the import machinery (it is like a shorter alias for config.import.<tool>.<tool>.exe that we already had). And the cli module now uses that instead of custom logic. This also adds support for uniform tool metadata extraction that is handled by the import machinery. As a result, a tool that follows the "build2 way" can be imported with metadata by the buildfile and/or corresponding module without any tool-specific code or brittleness associated with parsing --version or similar outputs. See the cli tool/module for details. Finally, two new flavors of the import directive are now supported: import! triggers immediate importation skipping any rule-specific logic while import? is optional import (analogous to using?). Note that optional import is always immediate. There is also the import-specific metadata attribute which can be specified for these two import flavors in order to trigger metadata importation. For example: import? [metadata] cli = cli%exe{cli} if ($cli != [null]) info "cli version $($cli:cli.version)"
