Now add timing calls at key phases. Let me find the phase boundaries.


Bash

grep -n 'Pass 1:.*scanning\|Pass 2:.*processing nodes\|Pass 3:.*processing ways\|Assembling admin\|Computing S2\|Deduplicating\.\.\.\|Writing index files\|std::cerr << "Done\."' builder/src/build_index.cpp | head -10

Phase boundaries


2041:            std::cerr << "  Pass 1: scanning relations..." << std::endl;
2066:            std::cerr << "  Pass 2: processing nodes in parallel..." << std::endl;
2189:            std::cerr << "  Pass 3: processing ways and areas with " << num_threads
2605:                    std::cerr << "  Assembling admin polygons in parallel ("

2867:        std::cerr << "Deduplicating..." << std::endl;
2883:    std::cerr << "Writing index files to " << output_dir << "..." << std::endl;

perf: add phase timers + optimize write phase

Phase timing output for each build stage. Write phase optimized by
eliminating hash map lookups (replaced with positional arrays) and
building output in memory buffers for single-write IO.

Check build error

Scope issue again. The `_pt` is declared inside a code block but used outside. Let me fix by moving the declaration up.


2041:        auto _pt = std::chrono::steady_clock::now();


  2038→            std::cerr << "Processing " << input_file << "..." << std::endl;
  2039→
  2040→            // --- Pass 1: collect relation members for multipolygon assembly ---
  2041→        auto _pt = std::chrono::steady_clock::now();
  2042→            std::cerr << "  Pass 1: scanning relations..." << std::endl;

            std::cerr << "Processing " << input_file << "..." << std::endl;

            // --- Pass 1: collect relation members for multipolygon assembly ---
        auto _pt = std::chrono::steady_clock::now();
            std::cerr << "  Pass 1: scanning relations..." << std::endl;


The `_pt` is at 8-space indent (inside the for loop) but the later log_phase calls are at 4-space indent (outside the for loop). Let me move it to function level.


Edit

            // --- Pass 1: collect relation members for multipolygon assembly ---
        auto _pt = std::chrono::steady_clock::now();

// --- Pass 1: collect relation members for multipolygon assembly ---
