| 9 | Version 0.5 |
|---|
| 10 | |
|---|
| 11 | This release makes a more complete agent. Most subbuffer types are |
|---|
| 12 | now supported, including user buffers, diagnostic buffers, and |
|---|
| 13 | user defined metrics. |
|---|
| 14 | |
|---|
| 15 | Performance has been improved using the Berkeley DB in-memory transaction |
|---|
| 16 | feature. This requires version 4.3 or later, so this is a change in the base |
|---|
| 17 | system requirements. The configuration program has been changed to reflect |
|---|
| 18 | this. |
|---|
| 19 | |
|---|
| 20 | There are some new and expanded tests in the test directory. This is the |
|---|
| 21 | first step in a validation test suite that will be expanded as development |
|---|
| 22 | goes on. |
|---|
| 23 | |
|---|
| 24 | A new debugging utility has been introduced. arm4_dump allows the developer |
|---|
| 25 | to view the contents of the repository database. This isn't meant to be a user |
|---|
| 26 | level tool. |

|---|
| 31 | 3 Add support for user-defined metrics |
|---|
| 32 | 24 Aliases should be at the library level, not the daemon |
|---|
| 33 | 22 Add ability to turn ARM collection on and off |
|---|
| 34 | 25 Add support for user buffers in transactions |
|---|
| 35 | 26 Add support for diagnostic details in transactions |

| 37 | Known Issues |
|---|
| 38 | |
|---|
| 39 | In certain cases, program crashes involving programs linked with libarm4 |
|---|
| 40 | may leave an open unnamed message queue. This will need to be removed |
|---|
| 41 | manually, or it will linger until the next reboot. |
|---|
| 42 | |
|---|
| 43 | |
|---|
| 44 | Version 0.4 |
|---|
| 45 | |
|---|
| 46 | The primary purpose of this release was to add an XMLRPC |
|---|
| 47 | reporting interface that could be used by web management tools, |
|---|
| 48 | but along the way many core deficiencies were uncovered and fixed. |
|---|
| 49 | |
|---|
| 50 | The structure of the ARM library and daemon have changed with |
|---|
| 51 | all of the database accesses having moved from the library to |
|---|
| 52 | the daemon. This results in more IPC calls, but greatly improves |
|---|
| 53 | the stability of the agent. |
|---|
| 54 | |
|---|
| 55 | The daemon now contains an XMLRPC interface that is being used to |
|---|
| 56 | develop a web management interface. This interface should not be |
|---|
| 57 | considered stable and is very likely to change as development continues. |
|---|
| 58 | |
|---|
| 59 | Some of the options to the daemon have changed in name and/or function, |
|---|
| 60 | so please read the documentation before using. |

| 62 | Tickets closed in this release: |
|---|

|---|
| 64 | 13 Berkeley DB permission errors cause database corruption |
|---|
| 65 | 12 Add XMLRPC based reporting interface |
|---|
| 66 | 15 API calls should accept empty ids |
|---|
| 67 | 19 Need to exit gracefully when daemon is unable to create shared regions |
|---|
| 68 | 21 The -r option to arm4_daemon doesn't remove the message queue |
|---|
| 69 | 16 arm_register_application accepts blank names and names with trailing blanks |
|---|
| 70 | 17 The -r option to arm4_daemon doesn't remove the databases as advertised |
|---|
| 71 | |
|---|
| 72 | Known Issues |
|---|
| 73 | |
|---|
| 74 | The agent doesn't currently support user defined metrics. This is |
|---|
| 75 | targeted for the next release. |
|---|
| 76 | |
|---|
| 77 | In certain cases, program crashes involving programs linked with libarm4 |
|---|
| 78 | may leave an open unnamed message queue. This will need to be removed |
|---|
| 79 | manually, or it will linger until the next reboot. |
