| | | | | | | | | | | | | | If the client finds that the server re-initializes a cached path/image, we consider this an error and invalid data. But since we might initialize a glyph using a fallback on the client, and receive the correct version from the server later, this is not longer true.

| | | | | | | | | | | | | | | | When allocating the mask for a fallback glyph, we allocate it on the arena on the SkScalerContext while the image belongs to a glyph on a different cache. This can lead to use-after-free bugs if accessing the image after the context owning that memory is destroyed. Fix this by allocating on the arena from the owning cache.

Currently the SkStrikeClient is designed to pull fonts from the server on demand, and to pre-fetch a batched request by analyzing the ops using a SkTextBlobCacheDiffCanvas. This change modifies the design to support a push based model, where the server pushes fonts required by the client and sets up the requisite SkGlyphCaches on the client prior to rasterizing the ops. This model still relies on the SkTextBlobCacheDiffCanvas for analyzing the glyphs required for rasterizing an op. The glyph caches required for raster are locked and missing glyphs to be sent to the client are tracked by the SkStrikeServer. The embedder can serialize this font data at any point, but must ensure that this data is deserialized by the SkStrikeClient at the remote end, before rasterizing any ops analyzed prior to serialization. Any refs on the caches are released once the font data is serialized by the server. The locking of glyph caches relies on the embedder providing discardable handles. These handles can be created on the server and serialized to be sent to the client, and map to an instance of SkGlyphCache. This allows the server to control the lifetime of the caches on the client.
