The adding of base:: was mostly prepared using git grep and sed: git grep -l <pattern> | grep -v base/vector.h | \ xargs sed -i 's/\b<pattern>\b/base::<pattern>/ with lots of manual clean-ups due to the resulting v8::internal::base::Vectors. #includes were fixed using: git grep -l "src/utils/vector.h" | \ axargs sed -i 's!src/utils/vector.h!src/base/vector.h!'

For Cobalt's purpose in the past, we introduced base::Memcpy to intercept memcpy calls and replace it with SbMemoryCopy on Starboard/Cobalt. Recently Cobalt removed SbMemoryCopy because we found out that memcpy implementation is universal. To reduce the cost to maintain base::Memcpy, let us remove it and revert back to raw memcpy.

This CL repurposes the v8.wasm trace event category, and introduces additionally the v8.wasm.detailed category. The v8.wasm category is enabled by default and captures core wasm events like validation, compilation, instantiation, and important operations like grow-memory and tier-up timings. The v8.wasm.detailed category is disabled by default. It captures all events the previous v8.wasm category captured, like compilation of single functions, time needed for register allocation, ... This CL splits these categories to allow enabling the v8.wasm category in telemetry benchmarks to calculate compile time and other metrics from traces of telemetry runs.

We are currently porting Chromium over to use the Perfetto client library for tracing[1]. When this mode is enabled, V8 should also use the Perfetto library built by Chromium instead of building an indepedendent copy. This patch enables that behavior, gated by the |use_perfetto_client_library| flag set by Chromium. We also roll Perfetto to the latest version, add a couple of missing dependencies on v8_tracing and add a missing tracing category group.

This patch replaces V8's tracing implementation (i.e., the TRACE_EVENT macros) with the track event base implementation from Perfetto. The advantages of doing this are: 1) This allows us to remove most tracing-related backend code from V8. 2) V8 can start writing strongly typed trace event arguments, which are more compact, easier to process and more extensible than legacy JSON-based trace arguments. For the time being, we still support the old trace macros when V8 is embedded into Chrome and other embedders.

Remove trace id mangling since it's been deprecated (and is also being removed) in Chromium [1] and the actual id mangling operation was never implemented in V8's version. This patch doesn't introduce the upstream replacement (TRACE_ID_{LOCAL,GLOBAL}), since nothing in V8 needs it and it'll be shortly brought in with the transition to the Perfetto client library[2].

The {SetTraceValue} method was only defined for a set of integer types, which sometimes lead to ambiguities when using types like {size_t}, {unsigned long} or the like (see https://crrev.com/c/1886912/1). This CL fixes that by providing a method accepting any integer type. It also changes the existing methods to avoid the "cast via union" idiom, and uses memcpy instead.

Previously both tracing implementations would be run side-by-side when perfetto was enabled with the V8_USE_PERFETTO build flag. This CL makes them run separately. Both implementations now use the trace file provided by the user in D8 or the default v8_trace.json. Add tests for perfetto events (which must be tested differently due to the proto output format). Drive-by fix: Fix pass-by non-const ref in GetJSONStrings. Remove the TraceEvent struct for testing; we can just store a copy of the protobuf directly.

This adds OBJECT/SNAPSHOT trace events for Script and SharedFunctionInfo objects, logging their creation with appropriate information to make sense of them. Based on that we introduces five flow events to model the optimized compilation via tracing in the "disabled-by-default-v8.compile" category: - "v8.optimizingCompile.start" logs the creation of the PipelineCompilationJob (for TurboFan JavaScript optimization) with the "function" argument referring to the trace event object created for the SharedFunctionInfo. - "v8.optimzingCompile.prepare" logs the preparation of the PipelineCompilationJob on the main thread, also carrying the "function" argument. This connects the flow event to the actual tracing duration event associated with the preparation phases. - "v8.optimizingCompile.execute" logs the (usually concurrent) optimization of the TurboFan graph (again with "function"). - "v8.optimizingCompile.finalize" logs the main thread phase which finalizes the optimized code and eventually installs it (in case of success). - "v8.optimizingCompile.end" signals the end of the PipelineCompilationJob, which carries the "compilationInfo", that contains the interesting bits of the OptimizedCompilationInfo, specifically whether the compile was successfull and which functions were inlined for example. This also adds two instant events "V8.AbortOptimization" and "V8.RetryOptimization" in "disabled-by-default-v8.compile" category that are emitted when TurboFan cannot optimize a certain function. In case of "V8.RetryOptimization", TurboFan might be able to optimize it later, whereas "V8.AbortOptimization" permanently disables the optimization of a given function. The JSON representation of this is ```js { "pid": 256639, "tid": 256639, "ts": 6935411377801, "tts": 159116, "ph": "I", "cat": "disabled-by-default-v8.compile", "name": "V8.AbortOptimization", "dur": 0, "tdur": 0, "args": { "reason": "Function is too big to be optimized", "function": { "id_ref": "0x600000001", "scope": "v8::internal::SharedFunctionInfo" } } }, ``` where the "function" refers to a previously emitted SNAPSHOT for the function in question. In the trace viewer it will show up as instant event under "v8.optimizingCompile.prepare" in case of the relevant example where optimization is disabled due to reaching the bytecode limit (as in the JSON above), i.e. it'll look something like this https://i.paste.pics/aafc2de9df10ea8f5acc1a761d80f07b.png for the example highlighted in the recent blog post https://ponyfoo.com/articles/javascript-performance-pitfalls-v8 that describes the optimization limit. The "v8.optimizingCompile.end" duration event will also carry this information as part of the "compilationInfo" object, but specifically for CI tools, etc. it might be a whole lot easier to just look for the "V8.AbortOptimization" instant event.

Inside V8 the TraceID class sits in v8::internal::tracing instead of trace_event_internal namespace (as in Chrome).

It's only used in tests, and for some reason v8 refers to a macro defined in src.git, so I need to remove this in v8 first before I can remove it in Chromium.
