> > Original change's description: > > [arraybuffer] Rearchitect backing store ownership > > > > This CL completely rearchitects the ownership of array buffer backing stores, > > consolidating ownership into a {BackingStore} C++ object that is tracked > > throughout V8 using unique_ptr and shared_ptr where appropriate. > > > > Overall, lifetime management is simpler and more explicit. The numerous > > ways that array buffers were initialized have been streamlined to one > > Attach() method on JSArrayBuffer. The array buffer tracker in the > > GC implementation now manages std::shared_ptr<BackingStore> pointers, > > and the construction and destruction of the BackingStore object itself > > handles the underlying page or embedder-allocated memory. > > > > The embedder API remains unchanged for now. We use the > > v8::ArrayBuffer::Contents struct to hide an additional shared_ptr to > > keep the backing store alive properly, even in the case of aliases > > from live heap objects. Thus the embedder has a lower chance of making > > a mistake. Long-term, we should move the embedder to a model where they > > manage backing stores using shared_ptr to an opaque backing store object. > > R=mlippautz@chromium.org > BUG=v8:9380,v8:9221,chromium:986318 > TBR=ulan@chromium.org > > Change-Id: I6c49e2425029b5664ef1c68dab8b5146f4ed0ff2 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1719191 > Reviewed-by: Ben Titzer <titzer@chromium.org> > Reviewed-by: Michael Starzinger <mstarzinger@chromium.org> > Commit-Queue: Ben Titzer <titzer@chromium.org> > Cr-Commit-Position: refs/heads/master@{#63007} TBR=mstarzinger@chromium.org,titzer@chromium.org,mlippautz@chromium.org Change-Id: If0266e5893b1325a332d5986337fa7ece2cb6943 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: v8:9380, v8:9221, chromium:986318 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1729549 Reviewed-by: Francis McCabe <fgm@chromium.org> Commit-Queue: Francis McCabe <fgm@chromium.org> Cr-Commit-Position: refs/heads/master@{#63011}
