Mobile devices may run applications, commonly known as “apps,” on behalf of their users. These applications may execute as processes on a device. These application may engage in network activity on the mobile device, such as may use wireless signals, including Wi-Fi, cellular data, and/or other technologies.
Cellular carriers may provide cellular data communication to their cellular customers. For example, smart phones and other mobile devices may run web browsers that may be used while on the cellular network to retrieve web pages. Additionally, many applications that may be pre-installed or user-installed on a mobile device may use cellular data communication to access remote data, such as resources available on the Internet.
The following presents a simplified summary in order to provide a basic understanding of some novel embodiments described herein. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Some concepts are presented in a simplified form as a prelude to the more detailed description that is presented later.
Various embodiments are generally directed to techniques for in-place directive execution. In one embodiment, for example, an apparatus may comprise a local network component operative to receive a directive package at a messaging client on a client device, the directive package formatted according to a serialized directive schema; and store the directive package in a memory of the client device in the serialized directive schema; and a local database synchronization component operative to execute the directive package using in-place access of the directive package in the memory of the client device. Other embodiments are described and claimed.
To the accomplishment of the foregoing and related ends, certain illustrative aspects are described herein in connection with the following description and the annexed drawings. These aspects are indicative of the various ways in which the principles disclosed herein can be practiced and all aspects and equivalents thereof are intended to be within the scope of the claimed subject matter. Other advantages and novel features will become apparent from the following detailed description when considered in conjunction with the drawings.
Users access a messaging system using a messaging client. Messaging servers of the messaging system interoperate with the messaging client to update the state of the messaging client. This may reflect the user receiving a message from another user via the messaging system, information about one or more of a user's contacts, messaging system notifications, or any other providing of information by the messaging system to the messaging client.
Various techniques may be used to update the state of a messaging client. In some embodiments, a messaging system may use a messaging synchronization scheme based around a complex messaging client using a complex messaging synchronization protocol where the synchronization protocol represents each of the various possible synchronization actions (e.g., providing a message, modifying contact state) via explicit synchronization commands each associated with a particular action and predefined in the synchronization protocol and on the messaging client. This technique has multiple disadvantages. The complexity of the client results in a large messaging client in terms of application binary and therefore increases both the storage space used for it on the client and the time used to load the messaging client into active memory on the client device. Further, a great many modifications to the operation of the messaging system involve modifications to the messaging client and therefore an application update on the client device.
Alternatively, a more streamlined synchronization protocol can be used. Instead of a complex synchronization protocol with individual messaging operations individually represented in the protocol, the synchronization protocol is built around updating a local database of the messaging client on the client device. The user interface of the messaging client is built to update itself exclusively using queries to the local database. As such, the messaging client is updated by the messaging servers updating the local database on the client device and then the user interface refreshing based on the updates to the local database. This may result in a smaller binary size for the messaging client as compared to other techniques, reducing the storage space used on the client device and the time used to load the messaging client into memory, increasing responsiveness. Further, many changes to the operation of the messaging client may be implemented by exclusively updating the operation of the messaging servers without any need to update the messaging client application.
Updates to the local database may be performed by sending database-update directives from the messaging servers to the messaging client. Database-update directives are commands instructing the messaging client how to update the local database. The database-update directives use a messaging-database-update command set specific to messaging database updating. A messaging-sync-specific virtual machine in the messaging client executes the database-update directives to update the local database and thereby provide messaging service to the messaging client.
The directives are generated on the messaging servers for the messaging client. The messaging servers generate the directives specifically for the messaging client, based on, for instance, the version of the messaging client as different versions of the messaging client may use different database schema and/or rely on different formats for messaging data.
The messaging servers execute messaging providers to generate the directives. A first layer of messaging providers determine high level operations that are agnostic to the messaging client version. These high level operations represent updates to the messaging client that are more recent than the current state of the messaging client. These high level operations are then translated to version-specific directives by a second layer of messaging providers specific to a particular database schema used by one or more versions of the messaging client. These version-specific directives are then provided to the messaging client to updates it local database.
As such, a messaging system may be implemented with a small, efficient client that uses little storage space on the client device and loads quickly. Further, the messaging system may be more significantly updated without modification of the messaging client application as compared to other synchronization techniques. Further, the messaging provider system may reduce the complexity of supporting multiple client versions.
Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. In other instances, well known structures and devices are shown in block diagram form in order to facilitate a description thereof. The intention is to cover all modifications, equivalents, and alternatives consistent with the claimed subject matter.
It is worthy to note that “a” and “b” and “c” and similar designators as used herein are intended to be variables representing any positive integer. Thus, for example, if an implementation sets a value for a=5, then a complete set of components 122 illustrated as components 122-1 through 122-a may include components 122-1, 122-2, 122-3, 122-4 and 122-5. The embodiments are not limited in this context.
The client messaging synchronization server system 110 may comprise one or more client messaging synchronization servers operated by a messaging platform as part of the messaging synchronization system 100. A client messaging synchronization server may comprise an Internet-accessible server, with the network 120 connecting the various devices of the messaging synchronization system 100 comprising, at least in part, the Internet.
A user may own and operate a smartphone device 150. The smartphone device 150 may comprise an iPhone® device, an Android® device, a Blackberry® device, or any other mobile computing device conforming to a smartphone form. The smartphone device 150 may be a cellular device capable of connecting to a network 120 via a cell system 130 using cellular signals 135. In some embodiments and in some cases the smartphone device 150 may additionally or alternatively use Wi-Fi or other networking technologies to connect to the network 120. The smartphone device 150 may execute a messaging client, web browser, or other local application to access the client messaging synchronization server system 110.
The same user may own and operate a tablet device 160. The tablet device 150 may comprise an iPad® device, an Android® tablet device, a Kindle Fire® device, or any other mobile computing device conforming to a tablet form. The tablet device 160 may be a Wi-Fi device capable of connecting to a network 120 via a Wi-Fi access point 140 using Wi-Fi signals 145. In some embodiments and in some cases the tablet device 160 may additionally or alternatively use cellular or other networking technologies to connect to the network 120. The tablet device 160 may execute a messaging client, web browser, or other local application to access the client messaging synchronization server system 110.
The same user may own and operate a personal computer device 180. The personal computer device 180 may comprise a Mac OS® device, Windows® device, Linux® device, or other computer device running another operating system. The personal computer device 180 may be an Ethernet device capable of connecting to a network 120 via an Ethernet connection. In some embodiments and in some cases the personal computer device 180 may additionally or alternatively use cellular, Wi-Fi, or other networking technologies to the network 120. The personal computer device 180 may execute a messaging client, web browser 170, or other local application to access the client messaging synchronization server system 110.
A messaging client may be a dedicated messaging client. A dedicated messaging client may be specifically associated with a messaging provider administering the messaging platform including the client messaging synchronization server system 110. A dedicated messaging client may be a general client operative to work with a plurality of different messaging providers including the messaging provider administering the messaging platform including the client messaging synchronization server system 110.
The messaging client may be a component of an application providing additional functionality. For example, a social networking service may provide a social networking application for use on a mobile device for accessing and using the social networking service. The social networking service may include messaging functionality such as may be provided by one or more elements of the client messaging synchronization server system 110. It will be appreciated that messaging servers for the client messaging synchronization server system 110 may be one component of a computing device for the social networking service, with the computing device providing additional functionality of the social networking service. Similarly, the social networking application may provide both messaging functionality and additional social networking functionality.
In some cases a messaging endpoint may retain state between user sessions and in some cases a messaging endpoint may relinquish state between user session. A messaging endpoint may use a local store to retain the current state of a message inbox. This local store may be saved in persistent storage such that the state may be retrieved between one session and the next, including situations in which, for example, a local application is quit or otherwise removed from memory or a device is powered off and on again. Alternatively, a messaging endpoint may use a memory cache to retain the current state of a message inbox but refrain from committing the state of the message inbox to persistent storage. The messaging endpoint may use a local store that is replicated across multiple devices, which may include one or both of other client devices and server devices.
A messaging endpoint that retains the state of a message inbox may comprise a dedicated messaging application or a messaging utility integrated into another local application, such as a social networking application. A messaging endpoint that relinquishes state of a message inbox may comprise messaging access implemented within a web browser. In one embodiment, a web browser, such as web browser 170 executing on personal computer device 180, may execute HTML code that interacts with the messaging server to present messaging functionality to a user.
A user may save and retrieve data from a plurality of devices, including the smartphone device 150, tablet device 160, and personal computer device 180. The user may use a first messaging application on the smartphone device 150, a second messaging application on the tablet device 160, and the web browser 170 on the personal computer device 180. The first and second messaging applications may comprise installations of the same application on both devices. The first and second messaging applications may comprise a smartphone-specific and a tablet-specific version of a common application. The first and second messaging application may comprise distinct applications.
The user may benefit from having their message inbox, application configurations, and/or other data kept consistent between their devices. A user may use their smartphone device 150 on the cell system 130 while away from their home, sending and receiving messages via the cells system 130. The user may stop by a coffee shop, or other location offering Wi-Fi, and connect their tablet device 160 to a Wi-Fi access point 140. The tablet device 160 may retrieve its existing known state for the message inbox and receive updates that have happened since the last occasion on which the tablet device 160 had access to a network, including any messages sent by the smartphone device 150 and that may have been received by the user while operating the smartphone device 150. The user may then return home and access their message inbox using a web browser 170 on a personal computer device 180. The web browser 170 may receive a snapshot of the current state of the message inbox from the client messaging synchronization server system 110 due to it not maintaining or otherwise not having access to an existing state for the message inbox. The web browser 170 may then retrieve incremental updates for any new changes to the state of the message inbox so long as it maintains a user session with the client messaging synchronization server system 110, discarding its known state for the message inbox at the end of the session, such as when the web browser 170 is closed by the user. Without limitation, an update may correspond to the addition of a message to a mailbox, a deletion of a message from a mailbox, and a read receipt.
The client messaging synchronization server system 110 may use knowledge generated from interactions in between users. The client messaging synchronization server system 110 may comprise a component of a social-networking system and may use knowledge generated from the broader interactions of the social-networking system. As such, to protect the privacy of the users of the client messaging synchronization server system 110 and the larger social-networking system, client messaging synchronization server system 110 may include an authorization server (or other suitable component(s)) that allows users to opt in to or opt out of having their actions logged by the client messaging synchronization server system 110 or shared with other systems (e.g., third-party systems), for example, by setting appropriate privacy settings. A privacy setting of a user may determine what information associated with the user may be logged, how information associated with the user may be logged, when information associated with the user may be logged, who may log information associated with the user, whom information associated with the user may be shared with, and for what purposes information associated with the user may be logged or shared. Authorization servers or other authorization components may be used to enforce one or more privacy settings of the users of the client messaging synchronization server system 110 and other elements of a social-networking system through blocking, data hashing, anonymization, or other suitable techniques as appropriate.
In particular embodiments, social graph 200 may include multiple nodes, which may include multiple user nodes 202 and multiple concept nodes 204. Social graph 200 may include multiple edges 206 connecting the nodes. In particular embodiments, a social-networking system, client system, third-party system, or any other system or device may access social graph 200 and related social-graph information for suitable applications. The nodes and edges of social graph 200 may be stored as data objects, for example, in a data store (such as a social-graph database). Such a data store may include one or more searchable or queryable indexes of nodes or edges of social graph 200.
In particular embodiments, a user node 202 may correspond to a user of the social-networking system. As an example and not by way of limitation, a user may be an individual (human user), an entity (e.g., an enterprise, business, or third-party application), or a group (e.g., of individuals or entities) that interacts or communicates with or over the social-networking system. In particular embodiments, when a user registers for an account with the social-networking system, the social-networking system may create a user node 202 corresponding to the user, and store the user node 202 in one or more data stores. Users and user nodes 202 described herein may, where appropriate, refer to registered users and user nodes 202 associated with registered users. In addition or as an alternative, users and user nodes 202 described herein may, where appropriate, refer to users that have not registered with the social-networking system. In particular embodiments, a user node 202 may be associated with information provided by a user or information gathered by various systems, including the social-networking system. As an example and not by way of limitation, a user may provide their name, profile picture, contact information, birth date, sex, marital status, family status, employment, education background, preferences, interests, or other demographic information. In particular embodiments, a user node 202 may be associated with one or more data objects corresponding to information associated with a user. In particular embodiments, a user node 202 may correspond to one or more webpages. A user node 202 may be associated with a unique user identifier for the user in the social-networking system.
In particular embodiments, a concept node 204 may correspond to a concept. As an example and not by way of limitation, a concept may correspond to a place (such as, for example, a movie theater, restaurant, landmark, or city); a website (such as, for example, a website associated with the social-network service or a third-party website associated with a web-application server); an entity (such as, for example, a person, business, group, sports team, or celebrity); a resource (such as, for example, an audio file, video file, digital photo, text file, structured document, or application) which may be located within the social-networking system or on an external server, such as a web-application server; real or intellectual property (such as, for example, a sculpture, painting, movie, game, song, idea, photograph, or written work); a game; an activity; an idea or theory; another suitable concept; or two or more such concepts. A concept node 204 may be associated with information of a concept provided by a user or information gathered by various systems, including the social-networking system. As an example and not by way of limitation, information of a concept may include a name or a title; one or more images (e.g., an image of the cover page of a book); a location (e.g., an address or a geographical location); a website (which may be associated with a URL); contact information (e.g., a phone number or an email address); other suitable concept information; or any suitable combination of such information. In particular embodiments, a concept node 204 may be associated with one or more data objects corresponding to information associated with concept node 204. In particular embodiments, a concept node 204 may correspond to one or more webpages.
In particular embodiments, a node in social graph 200 may represent or be represented by a webpage (which may be referred to as a “profile page”). Profile pages may be hosted by or accessible to the social-networking system. Profile pages may also be hosted on third-party websites associated with a third-party server. As an example and not by way of limitation, a profile page corresponding to a particular external webpage may be the particular external webpage and the profile page may correspond to a particular concept node 204. Profile pages may be viewable by all or a selected subset of other users. As an example and not by way of limitation, a user node 202 may have a corresponding user-profile page in which the corresponding user may add content, make declarations, or otherwise express himself or herself. A business page such as business page 205 may comprise a user-profile page for a commerce entity. As another example and not by way of limitation, a concept node 204 may have a corresponding concept-profile page in which one or more users may add content, make declarations, or express themselves, particularly in relation to the concept corresponding to concept node 204.
In particular embodiments, a concept node 204 may represent a third-party webpage or resource hosted by a third-party system. The third-party webpage or resource may include, among other elements, content, a selectable or other icon, or other inter-actable object (which may be implemented, for example, in JavaScript, AJAX, or PHP codes) representing an action or activity. As an example and not by way of limitation, a third-party webpage may include a selectable icon such as “like,” “check in,” “eat,” “recommend,” or another suitable action or activity. A user viewing the third-party webpage may perform an action by selecting one of the icons (e.g., “eat”), causing a client system to send to the social-networking system a message indicating the user's action. In response to the message, the social-networking system may create an edge (e.g., an “eat” edge) between a user node 202 corresponding to the user and a concept node 204 corresponding to the third-party webpage or resource and store edge 206 in one or more data stores.
In particular embodiments, a pair of nodes in social graph 200 may be connected to each other by one or more edges 206. An edge 206 connecting a pair of nodes may represent a relationship between the pair of nodes. In particular embodiments, an edge 206 may include or represent one or more data objects or attributes corresponding to the relationship between a pair of nodes. As an example and not by way of limitation, a first user may indicate that a second user is a “friend” of the first user. In response to this indication, the social-networking system may send a “friend request” to the second user. If the second user confirms the “friend request,” the social-networking system may create an edge 206 connecting the first user's user node 202 to the second user's user node 202 in social graph 200 and store edge 206 as social-graph information in one or more data stores. In the example of
In particular embodiments, an edge 206 between a user node 202 and a concept node 204 may represent a particular action or activity performed by a user associated with user node 202 toward a concept associated with a concept node 204. As an example and not by way of limitation, as illustrated in
In particular embodiments, the social-networking system may create an edge 206 between a user node 202 and a concept node 204 in social graph 200. As an example and not by way of limitation, a user viewing a concept-profile page (such as, for example, by using a web browser or a special-purpose application hosted by the user's client system) may indicate that he or she likes the concept represented by the concept node 204 by clicking or selecting a “Like” icon, which may cause the user's client system to send to the social-networking system a message indicating the user's liking of the concept associated with the concept-profile page. In response to the message, the social-networking system may create an edge 206 between user node 202 associated with the user and concept node 204, as illustrated by “like” edge 206 between the user and concept node 204. In particular embodiments, the social-networking system may store an edge 206 in one or more data stores. In particular embodiments, an edge 206 may be automatically formed by the social-networking system in response to a particular user action. As an example and not by way of limitation, if a first user uploads a picture, watches a movie, or listens to a song, an edge 206 may be formed between user node 202 corresponding to the first user and concept nodes 204 corresponding to those concepts. Although this disclosure describes forming particular edges 206 in particular manners, this disclosure contemplates forming any suitable edges 206 in any suitable manner.
The social graph 200 may further comprise a plurality of product nodes. Product nodes may represent particular products that may be associated with a particular business. A business may provide a product catalog to the consumer-to-business service 110 and the consumer-to-business service 110 may therefore represent each of the products within the product in the social graph 200 with each product being in a distinct product node. A product node may comprise information relating to the product, such as pricing information, descriptive information, manufacturer information, availability information, and other relevant information. For example, each of the items on a menu for a restaurant may be represented within the social graph 200 with a product node describing each of the items. A product node may be linked by an edge to the business providing the product. Where multiple businesses provide a product, each business may have a distinct product node associated with its providing of the product or may each link to the same product node. A product node may be linked by an edge to each user that has purchased, rated, owns, recommended, or viewed the product, with the edge describing the nature of the relationship (e.g., purchased, rated, owns, recommended, viewed, or other relationship). Each of the product nodes may be associated with a graph id and an associated merchant id by virtue of the linked merchant business. Products available from a business may therefore be communicated to a user by retrieving the available product nodes linked to the user node for the business within the social graph 200. The information for a product node may be manipulated by the social-networking system as a product object that encapsulates information regarding the referenced product.
The messaging synchronization system 100 may comprise a plurality of components. In some embodiments, these plurality of components may be distributed among a plurality of servers. In other embodiments, a single server may implement the plurality of components. In some embodiments, a plurality of servers may be executed by a single server device. In other embodiments, the plurality of servers may be executed by a plurality of server devices. In some embodiments, multiple instances of the various components and various servers may be executed to provide redundancy, improved scaling, and other benefits. Similarly, a client device may execute a plurality of components as part of a local client application.
A client device may communicate with other devices using wireless transmissions to exchange network traffic. Exchanging network traffic, such as may be included in the exchange of messaging or database synchronization transactions, may comprise sending and receiving network traffic via a network interface controller (NIC). A NIC comprises a hardware component connecting a computer device, such as client device, to a computer network. The NIC may be associated with a software network interface empowering software applications to access and use the NIC. Network traffic may be received over the computer network as signals transmitted over data links. The network traffic may be received by capturing these signals and interpreting them. The NIC may receive network traffic over the computer network and send the network traffic to memory storage accessible to software applications using a network interface application programming interface (API). The network interface controller may be used for the network activities of the embodiments described herein, including the interoperation of the clients and servers through network communication. For example, a client device sending or receiving messaging synchronization information to or from a server may be interpreted as using the network interface controller for network access to a communications network for the sending or receiving of data.
The messaging synchronization system 100 is operative to synchronize a local messaging database 329 with the current user state for a messaging system. The local messaging database 329 is stored on a client device 320 and used with a messaging application for the messaging system. The messaging synchronization system 100 includes a client messaging synchronization server system 110 providing transport for the providing of messaging synchronization information to a client device 320. Providing messaging synchronization information to a client device 320 is performed in a messaging synchronization exchange 310.
The client device 320 may comprise a plurality of components. The components may comprise elements of a local client application comprising a messaging client 325 executing on the client device 320. In general, the local application may comprise, without limitation, a messaging application and/or a social-networking application. In some embodiments, the messaging synchronization may be performed for a local messaging database 329 exclusively used by the messaging application 325 of which the components are an element. In other embodiments, the messaging synchronization may be performed for a local messaging database 329 used by a plurality of applications on the client device 320.
The messaging client 325 on the client device 320 may comprise a local network component 326. The local network component 326 may be generally arranged to manage the messaging synchronization exchange 310 with a server-side client communication component 330 that in which information is exchanged between the client device 320 and the client messaging synchronization server system 110 to provide messaging services to the client device 320.
The messaging client 325 on the client device 320 may comprise a local database synchronization component 323. The local database synchronization component 323 may be generally arranged to update a local messaging database 329 based on the messaging synchronization exchange 310 between the client device 320 and the client messaging synchronization server system 110. The local database synchronization component 323 may receive directives for updating the local messaging database 329 from the client messaging synchronization server system 110 and update the local messaging database 329 by executing the directives.
The messaging client 325 on the client device 320 may comprise a database access component 331. The database access component 331 may be generally arranged to access the local messaging database 329 and to intermediate between the local messaging database 329 and the local user interface components 321. The database access component 331 executes queries on behalf of the local user interface components 321 to provide them with updated data and modifies the local messaging database 329 in response to user interactions with the local user interface components 321.
The messaging client 325 on the client device 320 may comprise a plurality of local user interface components 321. The plurality of local user interface components 321 collectively comprise a user interface for the messaging client to the user of the client device 320 via the hardware components of the client device 320. The user interface may comprise visual elements, auditory elements, and/or other elements. The plurality of local user interface components 321 may be exclusively updated with the local messaging database 329 as an intermediary, such that all information used to update the user interface for the messaging client is provided to the plurality of local user interface components 321 via the modification of local messaging database 329 by directives processed by the local database synchronization component 323.
The client device 320 receives messaging services by interacting with, exchanging information with, a server-side client communication component 330. The server-side client communication component 330 is the access point for the client device 320 to the messaging system, with communication with the server-side client communication component 330 performed via a messaging synchronization exchange 310. The server-side client communication component 330 receives requests and other information from the client device 320 and provides information to the client device 320 from the other components of the messaging synchronization system 100.
A server-side client database management component 340 arranges directives for execution by the local database synchronization component 323 of a client device. The server-side client database management component 340 arranges the directives to, at least in part, deliver messages to the client device 320. Messaging, as well as other information, may be retrieved from a message 365 via a message queue management component, from a messaging backend store 370, and from a client information store 350. The messaging backend store 370 may comprise a long-term message archive that may be used to retrieve archived messages, which may be all messages that aren't sufficiently currently as to have not yet been archived by a message archival process. The client information store 350 may generally store client information other than messages.
A message queue 365 may queue—store and place an ordering on—a plurality of messages. The message queue 365 may comprise a representation of messages in a strict linear order. The message queue 365 may be organized as a data unit according to a variety of techniques. The message queue 365 may be stored in semi-persistent memory, persistent storage, both semi-persistent memory and persistent storage, or a combination of the two. The message queue 365 may be organized according to a variety of data structures, including linked lists, arrays, and other techniques for organizing queues. The message queue 365 may generally comprise a first-in-first-out (FIFO) queue in which no update will be removed or retrieved from the queue before any updates that were received prior to it. The message queue 365 may be managed by a message queue management component 360. The message queue management component 360 is generally arranged to provide messages for distribution to client devices, such as client device 320, to a server-side client database management component 340, which thereafter arranges directives to store the messages in the local messaging database 329 for eventual display to the user of the client device 320.
In some embodiments, a message queue 365 may be specifically associated with the user of client device 320, such as by being uniquely associated within the messaging synchronization system 100 with a user account for the user of client device 320. The message queue 365 may be a single queue used for all client devices used by this user. In these embodiments, each user of the messaging synchronization system 100 may have a message queue associated with their account, this message queue used to send messages to one or more client devices for that user.
An initial messaging synchronization is performed when a messaging client is initially configured. This may occur when a messaging client is initially installed on a client device 420. This may occur when a user first accesses or creates their account with the messaging system on the client device 420.
The client device 420 performs a client initial connection 413 with a gateway 440. The gateway 440 is the entry point for the client device 420 into the client messaging synchronization server system 110. The gateway 440 corresponds to the server-side client communication component 330 described with reference to
The gateway 440 then performs a gateway sync request 416 with a broker 460 in response to the client initial connection 413. The broker 460 generates the directives used to update the local messaging database of the client device 420. The broker 460 corresponds to the server-side client database management component 340 described with reference to
The broker 460 then performs a broker initial sync 419 with a data backend 480 in response to the gateway sync request 416. The broker initial sync 419 retrieves data from the data backend 480 to perform the initial sync of the client device 420. The data backend 480 may comprise the message queue management component 360, message queue 365, messaging backend store 370, and/or client information store 350 as described with reference to
The data backend 480 provides the initial sync data 423 to the broker 460. The broker 460 assembles the initial sync data 423 into directives that, when executed on the client device 420, update the local messaging database on the client device 420 to initialize the messaging state on the client device 420. These initial sync directives 426 are then provided to the gateway 440. The gateway 440 then provides them to the client device 420, which executes them to update its local messaging database.
A messaging synchronization resumption is performed when a messaging client resumes synchronization with the messaging system. The resumption of synchronization may correspond to a client connecting to the messaging system, via the gateway 440, after an initial synchronization has already been performed. The resumption of synchronization may generally correspond to a client requesting updates from the messaging system.
The client device 420 performs a client reconnection 463 with the gateway 440. The client reconnection 463 comprises a request to the gateway 440 to restart synching of the local messaging database for the client device 420.
The gateway 440 then performs a gateway sync resume 466 with the broker 460 in response to the client reconnection 463. The gateway sync resume 466 requests on behalf of the client device 420 that the broker 460 generate directives to perform a resumed synchronization of the client device 420. The gateway sync resume 466 includes identifying information associated with the client reconnection 463, such as may include a user identifier for the user of the client device 420, a messaging client identifier for a version of the messaging client, and/or other identifying information.
The broker 460 then performs a broker sync session 469 with the data backend 480 in response to the gateway sync resume 466. The broker sync session 469 retrieves data from the data backend 480 to perform a sync to update the client device 420 to the current state of a user's messaging inbox and general messaging state.
The data backend 480 provides the sync data 473 to the broker 460. The broker 460 assembles the sync data 473 into sync directives 476 that, when executed on the client device 420, update the local messaging database on the client device 420 to the updated messaging state for the user on the client device 420. These sync directives 476 are then provided to the gateway 440. The gateway 440 then provides the sync directives 476 to the client device 420 in a sync delivery 479, which executes them to update its local messaging database.
The client messaging synchronization server system 100 provides a directive package 510 to the messaging client 325 on a client device 320. The directive package 510 comprises a plurality of executable directives. The local network component 326 of the messaging client 325 on the client device 320 receives the directive package 510 from the client messaging synchronization server system 110 and provides it to the local database synchronization component 323. The local network component 325 provides the directive package 510 to the local database synchronization component 323 by storing the directive package in a memory of the client device 320 in the serialized directive schema. Storing the directive package 510 in the memory of the client device 320 comprises a direct non-rearranging copy from the received directive package 510, such that the local database synchronization component 323 accesses the executable directives with the executable directives stored in the same serialized directive schema used to transmit the directive package 510 from the client messaging synchronization server system 110 to the client device 320.
The directive package 510 is formatted according to a serialized directive schema. A serialized schema represents objects as a sequences of bits. Serialized schema are advantageous in sending objects, particularly complex objects, via a network. The executable directives are generated as an object, which is then converted to the serialized schema by the client messaging synchronization server system 110. The executable directives represented in the serialized directive schema comprise instructions to the local database synchronization component 323 for operations to perform against the local messaging database 329 to update the state of the messaging client 325 to reflect changes to the user's messaging inbox or other messaging information since the last update to the messaging client 325. The serialized schema may comprise the FlatBuffers schema or other known technique for serialized object representation, without limitation.
The local database synchronization component 323 comprises a directive execution component 550. The directive execution component 550 is operative to execute directives to update the messaging client 325. The directive execution component 550 may comprise a messaging-sync virtual machine dedicated to executing directives, such that the directive package is executed using the messaging-sync virtual machine.
The local database synchronization component 323 executes the directive package 510 using in-place access of the directive package 510 in the memory of the client device. Rather than copying the executable directives out of the direct package 510 the directive execution component 550 is operative to execute the directive package 510 directly from the memory location in which it was stored by the local network component 325 after reception from the client messaging synchronization server system 110. The directive execution component 550 may specifically execute the directive package 510 out of the memory the directive package 510 was stored in by the operating system of the client device 320, with that memory used to provide the directive package 510 to the messaging client 325 as part of direct memory access (DMA) or other networking technique.
The directive execution component 550 executes the directive package 510 using in-place access of the directive package 510 in the memory of the client device 320. The directive execution component 550 executes within a memory storage space of the serialized directive schema for the messaging client 325 and a memory stack for the client device. The directive package 510 is stored in a memory storage space within the memory of the client device 320 and can be executed in-place there. Any additional memory used in the execution of the directive package 510 is on the stack of the messaging client 325 and the directive execution component 550, without the use of heap allocation of memory storage space. This improves the performance of the execution of the directive package 510.
The serialized directive schema may encode an integrity check field, with the integrity check field defined as part of the specification of the serialized directive schema. The local database synchronization component 323 may verify the directive package based on the integrity check field to produce a successful verification of the directive package 510 using integrity-check-field-based verification techniques. The local database synchronization component 323 executes the directive package using in-place access of the directive package 510 in the memory of the client device 320 in response to the successful verification of the directive package 510 based on the integrity check field. The local database synchronization component 323 executes the directive package 510 only where the verification is successful and rejects the directive package 510—notifying the client messaging synchronization server system 110 of its rejection and thereby requesting a replacement—where the verification is unsuccessful.
The local database synchronization component 323 executes the directive package 510 with the directive execution component 550 to modify the local messaging database 329 of the messaging client 325. The executable directives of the directive package 510 specify database modifications 530 for the local messaging database 329. The directive execution component 550 performs the database modifications 530 based on the executable directives.
The local user interface components 321 of the messaging client 325 are operative to refresh using the local messaging database 329 as an intermediary to refresh in response to the directive package 510. Once the database modifications 530 prompted by the directive package 510 are complete, the local database synchronization component 323 refreshes one or more local user interface components 321 of the messaging client 320 in response to modifying the local messaging database 329 of the messaging client 320. The local database synchronization component 323 refreshes the one or more local user interface components 321 by notifying the database access component 331 of the update to the local messaging database 329. In response to the notification, the database access component 331 interoperates with the local user interface components 321 to refresh the local user interface of the messaging client 325 such that the database modifications 530 driven by the executable directives of the directive package 510 are represented in the user interface.

As used in this application, the terms “system” and “component” are intended to refer to a computer-related entity, either hardware, a combination of hardware and software, software, or software in execution, examples of which are provided by the exemplary computing architecture 900. For example, a component can be, but is not limited to being, a process running on a processor, a processor, a hard disk drive, multiple storage drives (of optical and/or magnetic storage medium), an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a server and the server can be a component.

Accordingly, functions and/or specific configurations of device 1100 described herein, may be included or omitted in various embodiments of device 1100, as suitably desired. In some embodiments, device 1100 may be configured to be compatible with protocols and frequencies associated one or more of the 3GPP LTE Specifications and/or IEEE 1102.16 Standards for WMANs, and/or other broadband wireless networks, cited herein, although the embodiments are not limited in this respect.
Embodiments of device 1100 may be implemented using single input single output (SISO) architectures. However, certain implementations may include multiple antennas (e.g., antennas 1118) for transmission and/or reception using adaptive antenna techniques for beamforming or spatial division multiple access (SDMA) and/or using MIMO communication techniques.
The components and features of device 1100 may be implemented using any combination of discrete circuitry, application specific integrated circuits (ASICs), logic gates and/or single chip architectures. Further, the features of device 1100 may be implemented using microcontrollers, programmable logic arrays and/or microprocessors or any combination of the foregoing where suitably appropriate. It is noted that hardware, firmware and/or software elements may be collectively or individually referred to herein as “logic” or “circuit.”
It should be appreciated that the exemplary device 1100 shown in the block diagram of
At least one computer-readable storage medium may comprise instructions that, when executed, cause a system to perform any of the computer-implemented methods described herein.
Some embodiments may be described using the expression “one embodiment” or “an embodiment” along with their derivatives. These terms mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment. Further, some embodiments may be described using the expression “coupled” and “connected” along with their derivatives. These terms are not necessarily intended as synonyms for each other. For example, some embodiments may be described using the terms “connected” and/or “coupled” to indicate that two or more elements are in direct physical or electrical contact with each other. The term “coupled,” however, may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other.
With general reference to notations and nomenclature used herein, the detailed descriptions herein may be presented in terms of program procedures executed on a computer or network of computers. These procedural descriptions and representations are used by those skilled in the art to most effectively convey the substance of their work to others skilled in the art.
A procedure is here, and generally, conceived to be a self-consistent sequence of operations leading to a desired result. These operations are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical, magnetic or optical signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It proves convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. It should be noted, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to those quantities.
Further, the manipulations performed are often referred to in terms, such as adding or comparing, which are commonly associated with mental operations performed by a human operator. No such capability of a human operator is necessary, or desirable in most cases, in any of the operations described herein which form part of one or more embodiments. Rather, the operations are machine operations. Useful machines for performing operations of various embodiments include general purpose digital computers or similar devices.
Various embodiments also relate to apparatus or systems for performing these operations. This apparatus may be specially constructed for the required purpose or it may comprise a general purpose computer as selectively activated or reconfigured by a computer program stored in the computer. The procedures presented herein are not inherently related to a particular computer or other apparatus. Various general purpose machines may be used with programs written in accordance with the teachings herein, or it may prove convenient to construct more specialized apparatus to perform the required method steps. The required structure for a variety of these machines will appear from the description given.
It is emphasized that the Abstract of the Disclosure is provided to allow a reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in a single embodiment for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separate embodiment. In the appended claims, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein,” respectively. Moreover, the terms “first,” “second,” “third,” and so forth, are used merely as labels, and are not intended to impose numerical requirements on their objects.
What has been described above includes examples of the disclosed architecture. It is, of course, not possible to describe every conceivable combination of components and/or methodologies, but one of ordinary skill in the art may recognize that many further combinations and permutations are possible. Accordingly, the novel architecture is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims.
