Abstract

A method of constructing a plurality of downloadable files from an application file and a plurality of transcripts. The application file stores data blocks and implements an application. Each of the transcripts stores at least one order in which at least a portion of the data blocks of the application file were accessed by the application when executed previously. The transcripts are combined into a combined transcript storing at least one combined order comprising a combined portion of the data blocks. The data blocks of the combined portion are arranged in a data structure having an origin. A first set of data blocks within a predetermined distance from the origin is stored in at least one initial execution file. A second set of data blocks outside the predetermined distance from the origin is stored in downloadable sequence files.

Claims

1. A computer-implemented method comprising:

receiving an instruction to construct a plurality of downloadable files from an application file and a plurality of transcripts, the application file implementing an application and comprising blocks of data, one or more of the plurality of transcripts being stored on another computing device;

in response to the instruction, retrieving the one or more transcripts from the another computing device by (a) copying the one or more transcripts to another storage location, (b) attempting to delete the one or more transcripts stored on the another computing device, and (c) when the attempt to delete a particular one of the one or more transcripts is unsuccessful, deleting the particular transcript from the another storage location;

after retrieving the one or more transcripts, combining the plurality of transcripts into a combined transcript, and each of the plurality of transcripts storing at least one order in which at least a portion of the blocks of data of the application file were accessed by the application when the application was executed previously at least once, the combined transcript storing at least one combined order comprising a combined portion of the blocks of data;

arranging the combined portion of the blocks of data in a data structure in accordance with the at least one combined order, the data structure having an origin corresponding to a first block of data accessed in the at least one combined order;

identifying a first set of blocks of data in the data structure within a predetermined distance from the origin block of data;

storing the first set of blocks of data in at least one downloadable initial execution file;

identifying a second set of blocks of data in the data structure outside the predetermined distance from the origin block of data; and

storing the second set of blocks of data in a plurality of downloadable sequence files.

2. The computer-implemented method of claim 1, wherein the application file is a virtualized application file that when executed, at least partially implements a virtual application.

3. The computer-implemented method of claim 1, wherein combining the plurality of transcripts into the combined transcript comprises:

identifying sets of like portions of the at least one orders of the plurality of transcripts; and

for each set identified, combining the like portions of the at least one orders of the plurality of transcripts in the set into an aggregated portion, the aggregated portion comprising a transition from a first block of data of the application file to a second block of data of the application file.

4. The computer-implemented method of claim 1, wherein the sequence files each have a file name, and the method further comprises:

identifying a third set of blocks of data not in the data structure;

storing the third set of blocks of data in a plurality of downloadable rest files each having a file name; and

storing the file names of the plurality of sequence files and the plurality of rest files in a downloadable model file to be downloaded with the at least one downloadable initial execution file before the plurality of downloadable sequence files and plurality of downloadable rest files are downloaded.

5. The computer-implemented method of claim 4, wherein in the model file, the file names of the plurality of sequence files are ordered in accordance with distances of the blocks of data stored in the plurality of sequence files from the origin block of data in the data structure, and the file names of the plurality of rest files are ordered in accordance with frequencies in which the blocks of data stored in the plurality of rest files appear in the combined transcript.

6. The computer-implemented method of claim 1, wherein when the application was executed previously at least once, the application launched a plurality of processes, and the at least one order stored by each of the plurality of transcripts comprises a separate order for each of the plurality of processes.

7. The computer-implemented method of claim 1, further comprising:

recording the construction of the plurality of downloadable files in a database, the database associating the plurality of downloadable files with the application and identifying a location whereat the plurality of downloadable files are stored.

8. The computer-implemented method of claim 1, wherein the data structure is a directed graph structure.

9. The computer-implemented method of claim 8, further comprising storing the directed graph structure in a model file specifying at least one order in which the plurality of downloadable sequence files may be accessed by the application as the application executes.

10. The computer-implemented method of claim 1, wherein when executed, the blocks of data stored in the at least one downloadable initial execution file partially implement the application but are insufficient to fully implement the application.

11. The computer-implemented method of claim 1, wherein storing the second set of blocks of data in the plurality of downloadable sequence files comprises storing each of the blocks of data in the second set in a separate one of the plurality of downloadable sequence files.
