Abstract

Improved methods of software diagnostics are provided. Searches of data sources are conducted using search terms from internal computer information to obtain searched data. The searched data is processed by extracting technical features. The technical features are indexed to create indexes that can be searched via machine state. Filtering is conducted over the gathered data to create feeds that are available to customers.

Claims

1. A method of performing software diagnostics, comprising:

conducting searches of data sources using search terms from internal computer information to obtain searched data,

processing the searched data by extracting technical features;

indexing the technical features to create indexes that can be searched via machine state, and

using filtering over the gathered data to create feeds that are available to customers.

2. The method of claim 1, further comprising:

data mining the gathered data.

3. The method of claim 1, further comprising:

using the new indexes to conduct the search.

4. The method of claim 1, further comprising:

summarizing.

5. The method of claim 1, wherein items from machine data are extracted from human data to be operated on to produce digested data as feeds.

6. The method of claim 5, wherein 3 stack trace matching is utilized.

7. The method of claim 1, further comprising:

using manual filtering on bug content

8. The method of claim 1, further comprising:

data mining customer responses.

9. The method of claim 1, further comprising:

using a feedback loop to provide the filtering.

10. The method of claim 7, further comprising:

triaging through the bugs to determine what is important.

11. The method of claim 10, wherein the triaging includes at least one of, marking and annotating issues, reasons to fix the bug, and reasons not to fix the bug.

12. The method of claim 11, wherein annotating is noted in a repository.

13. The method of claim 11, wherein annotations are attached to the bug and noted in a repository

14. The method of claim 1, wherein in response to the feed a customer is able to select a project and create a level of notification.

15. The method of claim 14, wherein the feed is created in a feed building process that includes going to a repository and from the repository putting together the feed with weightings for each of an item in a category.

16. The method of claim 15, further comprising:

remaining coupled to the repository until the feed process begins to create a custom feed for a customer.

17. The method of claim 14, wherein the repository is structured in a hierarchy directory structure.

18. The method of claim 17, wherein the hierarchy directory structure is used for improved search performance.

19. The method of claim 1, wherein digested data is made available to the customers through at least one of, a customized feed and an email.

20. The method of claim 1, wherein the data sources are selected from at least one of, mailing lists, newsgroups, bugs entered through community sites, changes in source code, security sites, an internal certification process and an internal bug tracking system.

21. The method of claim 1, further comprising:

extracting semi-structured information related to the software.

22. The method of claim 20, wherein extracting semi-structured information is performed using regular expressions that look for exception names.

23. The method of claim 1, further comprising:

extracting stack traces for the purpose of matching and researching using machine state rather than key words

24. The method of claim 22, further comprising:

creating a dictionary of classes and methods from the base source code, and

using the diction of classes and methods to pull out either stack traces, sample code or references to items.

25. The method of claim 23, wherein the dictionaries are build in part from on code related artifacts.

26. The method of claim 1, further comprising:

performing web scraping on at least security related sites.

27. The method of claim 23, further comprising:

using compiler tools to create the dictionaries; and

creating from the dictionaries a hash table or a suffix tree.

28. The method of claim 1, further comprising:

ranking the searched data using heuristics.

29. The method of claim 28, wherein the searched data is from mail threads.

30. The method of claim 29, further comprising:

determining a number of responses in the mail thread.

31. The method of claim 29, further comprising:

determining authorship of the mail threads.

32. The method of claim 29, further comprising:

determining if the mail thread is from a code check-in event.

33. The method of claim 29, further comprising:

determining if the mail thread is from a bug activity event.

34. The method of claim 28, wherein the searched data is from a bug.

35. The method of claim 34, further comprising:

determining how the bug was resolved.

36. The method of claim 34, further comprising:

determining who opened the bug.

37. The method of claim 34, further comprising:

determining who resolved the bug.

38. The method of claim 34, further comprising:

determining if the bug is fixed.

39. The method of claim 34, further comprising:

determining how long the bug has remained untouched by a software community.

40. The method of claim 28, wherein the searched data is code.

41. The method of claim 40, further comprising:

determining how check-in of the code effected code complexity.

42. The method of claim 40, further comprising:

determining an amount of churn that is created by check-in of the code.

43. The method of claim 40, further comprising:

determining how check-in of the code is related to a bug.

44. The method of claim 1, further comprising:

storing the searched data in a repository.

45. The method of claim 1, wherein the searched data includes extracted features of the data, connocal forms of the data and tags,

46. The method of claim 44, wherein the repository includes first and second indexes, the first index being an inverted index that is used for general full text searches, and the second index is used for matching stack traces.

47. The method of claim 1, further comprising:

looking through a bug tracking system for special fields that exist for each bug.

48. The method of claim 47, wherein the special fields are selected from at least one of, an original bug ID that is a URL to the original bug in the software, an external Issue type that marks the kind of issue it is and an external annotation that is the text describing the issue put in front of customers and will show up through feeds.

49. The method of claim 1, further comprising:

using a feed process that allows users to choose specifically what information is wanted and have these digests either sent through mail, or exposed as RSS.

50. The method of claim 1, wherein an user Interface is used to create configurable feeds through a web page.

51. The method of claim 1, further comprising:

52. The method of claim 51, further comprising:

allowing users to add, remove and modify functionality of feeds.

53. The method of claim 52, wherein the feeds are selected from at least one of, feed name, feed time period, description of what is in the feed, yes or no based on whether the feed should be sent as mail, and a URL to obtain the RSS feed from.

54. The method of claim 51, wherein at least a basic and an advanced feed are provided.

55. The method of claim 54, wherein the basic feed permits a user to, name the feed, select a choice of role, select a choice of stack, select a choice of time period and determine if the feed will be sent as mail.

56. The method of claim 1, further comprising:

creating configurable feeds.

57. The method of claim 56, wherein a repository, configurable feed portal and a feed generator are used to created the configurable feeds.
