uru auto on windows network share gets 'index out of range' error

[Benjamin Flanders]

When I do uru auto in a directory that has space I get an index out of range error. Here is the whole command line with error:

PS Microsoft.PowerShell.Core\FileSystem::\\FOXDC01\UserDocs\flanders\My Documents\dev\fox\Ruby2Projects\route_blaster> uru auto
panic: runtime error: index out of range

Opps Relevant system info: Windows 7 64bit running in powershell what else would help?

[Benjamin Flanders]

OK. it might not be spaces. I cd up one directory and I can uru auto without issue.

[Benjamin Flanders]

The .ruby_version file in :\FOXDC01\UserDocs\flanders\My Documents\dev\fox\Ruby2Projects contains 222.

When in this directory uru auto works as it should. In :\FOXDC01\UserDocs\flanders\My Documents\dev\fox\Ruby2Projects\route_blaster\ it panics, as it does in any directory under ruby2projects.

I tried putting a .ruby_version file in route blaster and it still panics.

[Jon]

Strange.

Show the results of running the following sequence in powershell and put the results in a code block formatted section so your results are readable. You can code block format via the 3rd icon from right in editing box, or surround your results with ~~~ console and ~~~ markdown syntax and click the Preview button before submitting.

1. $env:PATH
2. uru ver
3. uru ls --verbose
4. pwd
5. uru auto

Also, show what's in your %USERPROFILE%\.uru\rubies.json file.

If none of this helps us, I may ask you to download the 0.8.0.rc3 and have you run it in debug mode. Let's see what we find first with the version of uru you currently have installed.

[Jon]

I cannot repro your issue with the following test sequence. Although I'm likely using a different uru version than you are, there's been no change to the .ruby-version code. Something else is going on.

What uru and rubies do I have installed on my win8.1 x64 system?

darn there it is!!!!!!! I accidently had .ruby_version instead of .ruby-version

I changed it to .ruby-version and this fixed it.

Sir, you are a scholar and a genious. Thank you for helping and I am sorry I bothered you with this issue. While I am at it, thank you for putting uru out here.

[Benjamin Flanders]

So, I don't know the etiquette here, should I resolve the ticket? Should I change the title to uru crashes when it sees .ruby_version and let you resolve it?

[Benjamin Flanders]

Son of a motherless biscuit. I just created another project under Ruby2Projects, and I am getting the same error. You know, I don't think I am helping. Im so sorry.

so creating a .ruby-version file in this new directory fixes the issue. I remove it and I get the index out of range error.

I found the issue. (I think)

I think you nailed it regarding using raw network paths. In fact, it's likely code like this that needs to be refined.

While I don't like how uru panic'd on you (it should have failed more gracefully) I need to think a bit about if/how network shares should be handled. I'll likely never use uru with windows network shares, but I think it would be cool if uru could support it without too much added complexity.

If the following doesn't summarize how you would like to use uru, let me know:

1. All your rubies are installed on your local machine, not a network share (your uru ls --verbose omitted the details)
2. Regardless of whether the current dir is a local dir or a network share, you want to be able to use uru. You'd prefer not to need to map the network drive to a letter, but this isn't a showstopper for you.

[Benjamin Flanders]

You are correct. We have our home directories on our windows server, so going to "My Computer" goes to a synced network drive(done for backup purposes).

I do have all my rubies installed locally on the c: drive. It seems I missed the double dash in front of verbose, sorry.

I mapped a drive letter to the network location and everything is working, I don't know how the off line access will for for that location yet, but I'll try tonight. Regardless it isn't a show stopper for me.

Thank you for your help. You've been very patient and kind while I fumbled around trying to find the real issue after assuming something completely wrong, twice.

[Jon]

I'd like uru to support windows network shares and will need your help on these next steps:

1. Keep testing with your drive letter workaround. Document any further issues on this issue.
2. I'll create an entry in the FAQ's Troubleshooting section with the issue and drive letter workaround. Please review/refine to ensure correctness
3. I'll tweak the code to handle both \\share\path\to\somewhere and Y:\path\to\somewhere style dirs when searching for .ruby-version files. I'll ask you to test new builds. The tweak will not make it into the upcoming uru v0.8.0 release, but I think that is OK since your drive letter workaround appears to be working.
4. I'll keep the existing .ruby-version search algorithm for both path styles: walk up to the "root" dir and do a final fallback check in %USERPROFLE%. I like this behavior even with network shares because it allows us to create a default %USERPROFILE%\.ruby-version that works regardless of whether the current dir is on a local or remote machine.

We'll see how all this works out, but it might be as simple as fixing my original assumption of splitting on : as part of determining root dir.
