Abstract: A document preview system provides previews of a native document to client devices. The previews include comments associated with native objects in the native document. The document preview system identifies bounding areas in the preview associated with the native objects, which may be identified by the rendering markers applied to the native document prior to rendering. Using the bounding areas, the document preview system identifies comments for the native document and determines the location to display the comment using native objects associated with the comment. When a new comment is received from a user for a preview of a native document, the document preview system determines native objects for the new comment that match a user's selection for placing the new comment. The new comment is inserted with the native objects in the native document.

Abstract: In some embodiments, an interface of a content management system manages synchronized content on storage systems. For example, the interface stores, on a metadata storage structure, records of metadata associated with blocks of data stored on a storage, the records including block identifiers that uniquely identify the blocks and timestamps associated with the blocks. The interface identifies a batch of storage operations associated with the blocks, including one or more delete operations. For each delete operation, the interface queries the metadata storage structure for a timestamp corresponding to a block of data associated with the delete operation, determines whether the delete operation creates a race condition between the delete operation and an add operation associated with the block of data, and rejects the delete operation when the delete operation creates the race condition or the timestamp corresponding to the block of data is newer than a predetermined period of time.

Abstract: Techniques for image recompression. In one implementation, the techniques are implemented to recompress a baseline joint photographic experts group (JPEG) image with compression savings. The techniques replace the Huffman coding of baseline JPEG with an arithmetic coding that uses a sophisticated adaptive probability model. The arithmetic coding techniques avoid global operations such as global sorting that would prevent distributed and multithreaded decompression operations when recovering the original JPEG image from the recompressed image. At the same time, the techniques realize substantial compression savings relative to baseline JPEG, on average 23% compressing savings in some implementations.

Abstract: A document preview system provides previews of a native document to client devices. To generate the preview of a document, the document preview system generates a preview document that presents the native document in a browser-compatible format including elements that correspond to fields in the native document. The document preview system also identifies a mapping between fields of the native document and the elements of the preview. The document preview system also identifies a formula listing for the elements of the preview code. When a user edits a document, the edits may be committed to the document preview system and in parallel generate a preview to update the user's display. When an updated preview is available, the updated preview is rendered in a hidden frame and the user's input context is captured and reproduced when the updated preview replaces the prior preview.
