Consolidation C-6: streamr-logger

Sixth consolidation step (MODERNIZATION.md Phase 2.6), following the settled architecture: one named sub-module per former header, no umbrella, consumers and tests import exactly what they use.

What changed

  • The 11 headers (4 public: Logger, SLogger, StreamrLogLevel, LoggerImpl; 7 under detail/) became named sub-modules under modules/, with the detail units tree-mirroring in modules/detail/. Moved with git mv, history preserved.
  • The Phase 2.2 façade (streamr.logger umbrella + streamr.logger-all) and the include/ tree are deleted; the package no longer exports an include directory.
  • All 43 files across the repository with import streamr.logger; now import narrowly — for nearly all of them that is exactly import streamr.logger.SLogger;, so downstream rebuild cones shrink to the sub-modules actually used. One straggler flipped as well: the proxyclient integration test still included SLogger.hpp textually.
  • Logger's own tests import the detail sub-modules they exercise directly (streamr.logger.FollyLoggerImpl, .StreamrLogFormatter, …) — tests know module internals, per the settled rule.
  • streamr-json usage inside the logger units (SLogger/Logger call streamr::json::toJson) deliberately stays a textual global-module-fragment include: streamr-json is still a header package until C-7 consolidates it.
  • Logger's lint now runs clangd-tidy over the module units (consolidated posture).

Two new purview-migration findings (recorded in MODERNIZATION.md for C-7/C-8)

  1. Namespace-scope static constexpr constants cannot be exported — internal linkage. The detail color constants became inline constexpr when they moved into module purview. Harmless in a header; a hard compile error in an exported namespace.
  2. A C symbol declared in module purview silently gets module attachment. extern char** environ; inside FollyLoggerImpl produced an undefined symbol environ@streamr.logger.FollyLoggerImpl at link time — the declaration no longer matched the libc symbol. Such declarations belong in the global module fragment (now extern "C" char** environ; there, with a comment).

Verification

  • Whole-monorepo build clean; 309/309 tests pass (run with per-test timeouts).
  • Standalone chain green: logger (63/63 tests) → utils (49/49) → proto-rpc (26/26) → dht (83/83) → trackerless-network (build) → libstreamrproxyclient (15/15).
  • Lint green in all six touched packages.
  • [androidbuild] [iosbuild] tags request the cross-platform CI legs.
  • Pushed with --no-verify (known pre-push-hook SIGPIPE issue); lint scripts run manually instead.

Next step (C-7)

streamr-json consolidation — after it, the textual streamr-json/toJson.hpp include in the logger units flips to an import.

…es [androidbuild] [iosbuild]

One streamr.logger.X sub-module per former header (detail/ internals
included, tree-mirroring), no umbrella, include/ tree deleted, 43
importers flipped to narrow imports (nearly all just SLogger).
streamr-json stays a textual global-module-fragment include until C-7.
Two purview-migration findings recorded: namespace-scope static
constexpr must become inline constexpr to be exportable, and C symbol
declarations (extern char** environ) must stay in the global module
fragment or they get module attachment and break the link.

…e known Linux preamble/BMI std-type unification false positive

The linux-arm64 lint leg failed with spurious 'cannot initialize object
parameter of type const std::basic_string<char> with an expression of
type std::string' on every gtest assertion in the file — the documented
clangd failure class when standard-library types cross module
boundaries. The macOS clangd of the same major version accepts the
file and the compiler accepts it on every platform; clang-format still
covers it. Owner-approved selective disabling (fourth exclusion).
