Change ScriptCompiler::CompileOptions to allow for two 'cache' modes
(parser or code) and to be explicit about cache consumption or production
(rather than making presence of cached_data imply one or the other.)
Also add a --cache flag to d8, to allow testing the functionality.
-----------------------------
API change
Reason: Currently, V8 supports a 'parser cache' for repeatedly executing the same script. We'd like to add a 2nd mode that would cache code, and would like to let the embedder decide which mode they chose (if any).
Note: Previously, the 'use cached data' property was implied by the presence of the cached data itself. (That is, kNoCompileOptions and source->cached_data != NULL.) That is no longer sufficient, since the presence of data is no longer sufficient to determine /which kind/ of data is present.
Changes from old behaviour:
- If you previously didn't use caching, nothing changes.
Example:
v8::CompileUnbound(isolate, source, kNoCompileOptions);
- If you previously used caching, it worked like this:
- 1st run:
v8::CompileUnbound(isolate, source, kProduceToCache);
Then, source->cached_data would contain the
data-to-be cached. This remains the same, except you
need to tell V8 which type of data you want.
v8::CompileUnbound(isolate, source, kProduceParserCache);
- 2nd run:
v8::CompileUnbound(isolate, source, kNoCompileOptions);
with source->cached_data set to the data you received in
the first run. This will now ignore the cached data, and
you need to explicitly tell V8 to use it:
v8::CompileUnbound(isolate, source, kConsumeParserCache);

Change ScriptCompiler::CompileOptions to allow for two 'cache' modes
(parser or code) and to be explicit about cache consumption or production
(rather than making presence of cached_data imply one or the other.)
Also add a --cache flag to d8, to allow testing the functionality.
-----------------------------
API change
Reason: Currently, V8 supports a 'parser cache' for repeatedly executing the same script. We'd like to add a 2nd mode that would cache code, and would like to let the embedder decide which mode they chose (if any).
Note: Previously, the 'use cached data' property was implied by the presence of the cached data itself. (That is, kNoCompileOptions and source->cached_data != NULL.) That is no longer sufficient, since the presence of data is no longer sufficient to determine /which kind/ of data is present.
Changes from old behaviour:
- If you previously didn't use caching, nothing changes.
Example:
v8::CompileUnbound(isolate, source, kNoCompileOptions);
- If you previously used caching, it worked like this:
- 1st run:
v8::CompileUnbound(isolate, source, kProduceToCache);
Then, source->cached_data would contain the
data-to-be cached. This remains the same, except you
need to tell V8 which type of data you want.
v8::CompileUnbound(isolate, source, kProduceParserCache);
- 2nd run:
v8::CompileUnbound(isolate, source, kNoCompileOptions);
with source->cached_data set to the data you received in
the first run. This will now ignore the cached data, and
you need to explicitly tell V8 to use it:
v8::CompileUnbound(isolate, source, kConsumeParserCache);
