perf: avoid allocating the assigned worker path prefix (#2755)
When a worker is explicitly assigned, deriving SCRIPT_NAME builds
`documentRoot + separator` and then checks the document-root prefix a
second time in `TrimPrefix`. For roots longer than the temporary string
buffer, this also allocates on every request.
Check the length, separator byte and root prefix directly, then slice
the verified root prefix. Keep `filepath.ToSlash`, the original handling
of workers outside the root, and all SCRIPT_NAME/PATH_INFO values
unchanged. No cache or request fields are added.
Added boundary cases and differential fuzzing against the previous full
`splitCgiPath`, plus a reusable `BenchmarkAssignedWorkerScriptPath`. The
benchmark includes the whole function for explicitly assigned workers,
rather than only the prefix expression.
## Validation
Covers inside/outside/neighboring roots, equal and empty paths,
filesystem roots, trailing/repeated separators, long roots, Unicode, NUL
and invalid UTF-8. Differential fuzzing varies root, worker filename and
request path, comparing the complete resulting context with the previous
implementation.
- Isolated committed tests pass with `-race` against **both** versions.
- Fuzzing the final implementation: **1,386,376 executions in 20
seconds**, four workers, no failures.
- `gofmt` and `git diff --check` pass.
- Native package test was attempted via `./go.sh test -tags nowatcher
-run '^TestAssignedWorkerScriptPath$' -count=1 .`; compilation stops at
missing `sapi/embed/php_embed.h`. Local PHP 8.5.12 is NTS. Native
callback/C integration, full FrankenPHP/Caddy suites and end-to-end load
tests have **not** passed locally; they require a supported embed/ZTS
environment.
## Time and allocation measurements
Baseline: `d138a78717413a589cb9af097483024c19f6ae92` (main). PR head:
`02313c063270e3497b5b35debb31a526a54fde2b`. Apple M2, darwin/arm64,
macOS 27.0, Go 1.27.3. This PR is independently based on main.
The standalone harness extracts `splitCgiPath` and its helpers from the
baseline and this PR without changing their bodies. It uses the
production context declaration, committed tests/benchmark, and minimal
worker/server stubs. It does not link PHP. Neither version includes
changes from the separate splitPos PR.
Ten before/after pairs, alternating which version runs first,
`-test.cpu=1 -test.benchmem`, 150ms per sub-benchmark. Separate
optimized binaries, without race instrumentation or PGO. Setup is
outside `b.Loop`, and results are consumed. Table entries are median and
observed min-max in ns/op, not confidence intervals. Positive time
reduction means faster. These are operation microbenchmarks, **not whole
HTTP-request throughput**. These final measurements supersede the
earlier narrower helper timings.
| Scenario | Before ns/op (min-max) | After ns/op (min-max) | Time
reduction | B/op before -> after | allocs/op before -> after |
| --- | ---: | ---: | ---: | ---: | ---: |
| `short_root` | 28.400 (28.330-32.800) | 15.750 (15.720-18.360) |
+44.5% | 0 -> 0 | 0 -> 0 |
| `long_root` | 49.940 (49.670-50.250) | 17.240 (17.170-17.440) | +65.5%
| 64 -> 0 | 1 -> 0 |
| `outside_root` | 42.715 (42.470-43.010) | 14.555 (14.490-14.580) |
+65.9% | 64 -> 0 | 1 -> 0 |
| `empty_root` | 21.045 (20.950-23.990) | 15.445 (15.410-15.550) |
+26.6% | 0 -> 0 | 0 -> 0 |
| `trailing_separator` | 28.505 (28.360-28.690) | 15.760 (15.700-16.320)
| +44.7% | 0 -> 0 | 0 -> 0 |
| `exact_root` | 25.785 (25.700-26.620) | 14.545 (14.520-14.570) |
+43.6% | 0 -> 0 | 0 -> 0 |
Heap allocation numbers count Go allocations during each operation. The
optimization adds no cache or persistent state. Whole-process RSS,
retained-process memory and PHP/C allocations were not measured, so
zero/reduced B/op is not claimed to prove unchanged RSS.
## Stack measurements
Generated optimized compiler assembly (`go test -c -gcflags=-S`) for the
same standalone function bodies:
| Target | Before direct frame | After direct frame | Change |
| --- | ---: | ---: | ---: |
| darwin/arm64 | 160 B | 128 B | -32 B |
| linux/amd64 | 144 B | 88 B | -56 B |
| windows/amd64 | 144 B | 88 B | -56 B |
These are direct frames in the isolated Go compilation, not total nested
stack peaks or native cgo-export wrapper frames. Linux and Windows were
cross-compiled only; no runtime speed or test execution on those targets
is claimed.
## Reproduction
With supported PHP embed/ZTS development libraries installed, run the
committed tests in the repository:
```sh
./go.sh test -race -run '^(TestAssignedWorkerScriptPath|FuzzAssignedWorkerScriptPath)' .
./go.sh test -run '^$' -bench '^BenchmarkAssignedWorkerScriptPath$' -benchmem -count=10 -benchtime=150ms -cpu=1 .
./go.sh test -run '^$' -fuzz '^FuzzAssignedWorkerScriptPath$' -fuzztime=20s -parallel=4 .
```
The following script reproduces the actual isolated timing setup without
PHP. Save it outside the checkout and run it with Python 3 **from this
PR checkout**. It extracts the baseline/current source, copies the
committed tests, runs race checks, emits compiler assembly, and
alternates ten benchmark pairs. For the output PR, the script also
includes its Go-only benchmark fixture.
