Iguana checks out the code that it is working on from Git into a local “sandbox” directory (<Iguana-install-directory>/edit/<user name>/). In an emergency you can edit this code directly. For example if Iguana is crashing when you open a script, then you could edit it manually to resolve the issue.
Running Iguana from the command line [top]
If you in a situation where Iguana is crashing then one helpful trick is to start Iguana as a command line process. You’ll need to go to the directory where Iguana is installed and run the Iguana executable (
iguana.exe) at the command line. If Iguana is crashing on startup you can run Iguana in safe mode, which prevents any channels from auto-starting.
When you run Iguana from the command line it outputs various information, including: Configuration file issues, database issues, port conflicts, etc.
This allows you to diagnose issues such as:
- Incompatible versions of Chameleon, you should be using the version of Chameleon (or higher) that’s shipped with Iguana.
- Port conflicts, you may have applications on your system that are already listening on ports that Iguana wants to use.
- Other issue that may cause problems with running Iguana as a service/daemon
Note: When running Iguana from the command line it uses the current user permissions, not the permissions for admin or localsystem (or the service/daemon user).
If any of your code needs special access you will need to logon as a user with sufficient permissions, for example: The service/daemon user.
cd C:\Program Files\iNTERFACEWARE
iguana --run --safe_mode(optionally add safe mode to prevent channels starting)
- Use Ctrl+c to stop the server
./iguana --run --safe_mode(optionally add safe mode to prevent channels starting)
- Use cmd+c to stop the server
Note: If necessary substitute your own install directory above (step 1).
See deployment FAQs for more detailed information. Particularly: “How to run Iguana from the command line” for detailed command line output.
Delete corrupt index files [top]
One problem that can occur is if the index files for the logs have been corrupted. You might see a SQLite error referencing a malformed database image.
This can solved easily without loss of data:
- Go to the directory Iguana has configured to store it’s logs.
- Delete the contents of the subdirectory “index” – this contains the SQLlite index files.
- Optionally delete the contents of the subdirectory “meta” – this is another type of index stored in XML format.
The data for the logs is stored in the files with a *.log. Iguana will rebuild the index files from these core log files if the index files are deleted.
