[GitHub] [nifi] exceptionfactory opened a new pull request, #6370: NIFI-9500 Add nifi.cmd for Windows

exceptionfactory opened a new pull request, #6370:
URL: https://github.com/apache/nifi/pull/6370

   # Summary
   
   [NIFI-9500](https://issues.apache.org/jira/browse/NIFI-9500) Adds a `nifi.cmd` script for running application actions on Windows. 
   
   The implementation contains a basic set of capabilities similar to `nifi.sh`, including support for the `set-single-user-credentials`, `set-sensitive-properties-key`, and `set-sensitive-properties-algorithm` commands.
   
   The script leverages a new `nifi-env.cmd` to avoid depending on the current `nifi-env.bat` script. The `cmd` approach and current directory resolution avoids directory name truncation artifacts present in the `bat` versions.
   
   This implementation should provide a way forward for support on Windows, with the opportunity to deprecate the `bat` files in a future major release version.

Review Comment:
   Unlike the `nifi.sh` script, the `nifi.cmd` script on Windows is not able to run a command in the background, so the `start` and `run` actions keep the process in the foreground. This follows the existing behavior of the `run-nifi.bat` script. There may be more advanced approaches that could be implemented with PowerShell, but it seems like it would be better to consider them as future capabilities.

   Thanks for the feedback @greyp9! I pushed an update to change to the NiFi Home directory while running the command action, following the pattern of the `nifi.sh` script.

   Would it make more sense to use PowerShell given that that seems to be the modern standard for Windows Server?

   > Would it make more sense to use PowerShell given that that seems to be the modern standard for Windows Server?
   
   That's a good question. NiFi should also be capable of running on Windows 10 and 11, in addition to Windows Server, but both of those versions also support PowerShell. Introducing this `cmd` version should provide the greatest degree of compatibility, but following up with a PowerShell version and replacing this and other `bat` scripts seems worth considering.

Review Comment:
   The command `stop` seems to be recognized as such by the `RunNiFi` main class, but the `start` and `run` commands seem to behave the same.  I expect `start` to spawn the process, and return to the command prompt, where `run` should continue interacting with the console window until the Ctrl+C signal is sent.  But both commands remain interactive, and the `stop` command, while writing the expected output to stdout, does not actually stop the process.

Review Comment:
   I typically run this command on MacOS from $NIFI_ROOT, rather than from $NIFI_ASSEMBLY_DIR:
   
   `./nifi-assembly/target/nifi-1.18.0-SNAPSHOT-bin/nifi-1.18.0-SNAPSHOT/bin/nifi.sh set-single-user-credentials user password`
   
   On Windows, the script works from $NIFI_ASSEMBLY_DIR:
   
   ```
   nifi\nifi-assembly\target\nifi-1.18.0-SNAPSHOT-bin\nifi-1.18.0-SNAPSHOT>bin\nifi.cmd set-single-user-credentials user password
   
   Login Identity Providers Processed [nifi\nifi-assembly\target\nifi-1.18.0-SNAPSHOT-bin\nifi-1.18.0-SNAPSHOT\.\conf\login-identity-providers.xml]
   ```
   
   but not from $NIFI_ROOT:
   
   ```
   nifi>nifi-assembly\target\nifi-1.18.0-SNAPSHOT-bin\nifi-1.18.0-SNAPSHOT\bin\nifi.cmd set-single-user-credentials user password

Review Comment:
   Thanks for point out this issue @greyp9.
   
   The `SetSingleUserCredentials` command class attempts to resolve the `login-identity-providers.xml` from the current working directory. The `nifi.sh` script changes to the NiFi Home directory prior to running the command, so I updated the `nifi.cmd` to take the same approach, so both approaches described should now work as expected.
