Add HTTPS support

Add support for serving over HTTPS.

Branch is ...

Make sure web pages work.

server.js should have two new command line arguments that are empty strings by default.

--cert
--key

If these are non-empty strings, they are assumed to be files and read. If read fails, exit. Otherwise, start https server.

In the documentation, we should add instructions for using https. For example, following https://nodejs.org/en/knowledge/HTTP/servers/how-to-create-a-HTTPS-server/

openssl genrsa -out key.pem
openssl req -new -key key.pem -out csr.pem
openssl x509 -req -days 9999 -in csr.pem -signkey key.pem -out cert.pem
rm csr.pem
./hapi-server --cert /path/to/cert.pem --key /path/to/key.pem 

A test should be added that creates the certificates and runs the test suite using an https server.

The behavior of execSync does seem to be uniform across all the platforms. The execSync seems to work flawlessly in the UNIX environment. But, in windows, when running the subsetting tests, the execSync is failing to execute the command. Whereas using exec/spawn asynchronously works well. Can we run the respective command based on the OS (process.env)?

Your first sentence contradicts your second sentence. Anyway, I think that in all cases we should use spawn. In the tests, await should be used to block. This code may have some hints if you run into issues: https://www.npmjs.com/package/cross-spawn

I am sorry. I meant to say the behavior is not constant. Will try cross-spawn and give an update.

The initial problem with spawn in ubuntu was that the function is not halting for the subprocess to fetch the data and terminate. I have fixed this by making sure the function returns only after the data is returned and the child is exited Yet, the same approach in windows is throwing the ENONET error. I tried the following workarounds :

1. Command having spaces in it

2. Usage of option {shell:true}

3. Tried cross-spawn and spawn-cmd

Still, the error persists in windows and trying to resolve it.

[rweigel]

Would you post the minimal code that shows error in Windows? For example, something that spawns a call to python that executes a script that only prints a string.

Actually just fixed the error. This is a path issue related to $NODEEXE having spaces within it. In windows, $NODEEXE breaks down to "C:\Program Files\nodejs\node.exe" in the background where there is a space in between the command. This error is not encountered in ubuntu since $NODEEXE breaks down to something like "/usr/bin/node" (no spaces). Enclosing the $NODEEXE within the quotes i.e
\"$NODEEXE\" fixed the issue.

Actually, it turns out that, the command to generate the catalog file, is not being treated as command, but as file in the getmetadata function. There seems to be issue with commandExistsSync to treat cd as a command in windows. Working on the way to modify the command inorder to make it work.

[rweigel]

OK. But this does make me wonder about the wisdom of having to check if it is a file or command. Probably the schema should be changed so that one gives either metadata (JSON), metadataFile (string; local path), or metadataURL (string; URL) instead of allowing metadata to be any of the three.

[KSR4599]

Yes, that would also remove the need to check for all the three conditions each time. Going with the option of metadataFile ( i.e local path) would be straight forward. For which we need to generate the catalog file well in advance before giving it as the local path to the catalog section.

[rweigel]

I suggest doing this then. You'll need to update all of the .json files in the metadata/ directory.

Will the exec function work in Windows if we make this change? I don't like the fact that the buffer size is hard-wired. It seems spawn is more appropriate for an unknown response size.

[KSR4599]

Yes, I will work on updating the files in metadata dir. As you mentioned, usage of spawn shall remove the need to hard-code the buffer limit. I will appropriately replace exec with spawn.
