## 1 Inviso Release Notes

This document describes the changes made to the Inviso application.

### 1.1 Inviso 0.4

#### 1.1.1 Fixed Bugs and Malfunctions

- A bug in inviso_rt_meta caused an ETS table containing information on initiated (init_tpm) functions to be lost when suspending tracing. Further an enhancement to inviso_rt has been introduced making it possible to activate process trace flags based on globally registered names. It is then not an error to activate a global name on a node where the name does not reside. The process count in the return value will simply be set to zero (hence exactly one node in the NodeResult part of the return value will indicate one matching process found). A bug was found in fetch_log API. At the same time the fetch_log functionality was enhanced to also offer flow control making fetcher processes send chunks of transferred file data at a slower pace.

### 1.4 Inviso 0.2

#### 1.4.1 Fixed Bugs and Malfunctions

- This ticket includes several improvements and bugfixes to both runtime_tools and inviso. The overload mechanism can now also react to incomming messages. This is useful if an external overload watch-dog is used. Some improvements of variable bindings has been done to the default autostart mechanism - inviso_autostart_server. Autostart "jobs" can now be done in paralell, allowing for some jobs to hang waiting for some parts of the traced system to become ready before proceeding. Previously when using named meta-match-specs (tpm_ms) ending up with zero match-specs still kept the meta trace pattern active. This caused zero match-specs to be equal to unlimited meta tracing on that particular function. If the internal database becomes empty of meta match specs, meta trace pattern is removed for that function. Standard public loop data in the inviso runtime meta tracer process is now extended to a 2-tuple. The functions ctp/1 and ctpl/1 are added making it possible to remove trace patterns for a list of functions rather than one by one. Inviso_rt_meta will now accept a list of binaries to be output into the trace information file, in additions to a single binary. Further it is also possible to make own output to the trace information file using the write_ti/1 function. An error was discovered in inviso_rt making the inviso_rt_meta remain rather than terminate if the inviso_rt terminated due to "running alone" (not allowed to run without a control component). A new tool, inviso_tool, has been added to the inviso application.
