Windows: paths are not completely handled #5

I'm on Windows with latest racket and pollen.

What I did was cd to my working directory then ran this command:

"C:\Program Files\Racket\raco" pollen start

The index.ptree works, I can also access files in the folder that are not processed by pollen. However, when I click on spec.html.pm; I get this:

route-404: Can't find C:\Users\Adrien\Downloads\project\c\users\adrien\downloads\project\spec.html

Notice the stray path here.

Now cd'ing to racket directory and running it from here with a custom project path, I have basically the same error pattern but with racket path:

route-404: Can't find C:\Users\Adrien\Downloads\project\c\program files\racket\spec.html

Basically the same but with Racket's path.
For reference the command ran here was:

raco pollen start "C:\Users\Adrien\Downloads\project"

@mbutterick; Note that it's the first time I'm using Racket so I may be doing something wrong.

More likely I'm doing something dumb with Windows paths.

I'll have a look...

Thanks, just ran into something weirder: it now works... but I haven't actually changed anything.

The log shows this:

Servlet (@ /) exception:
bytes->path: path string is empty

  context...:
   C:\Program Files\Racket\collects\net\url.rkt:154:0: file://->path4
   req->path

0: route-default
   C:\Program Files\Racket\share\pkgs\web-server-lib\web-server\dispatchers\disp
atch-servlets.rkt:58:2

Seems like that stray path is now considered empty internally?

I was able to reproduce this problem. There were a couple places in the code where I wasn't handling Windows paths correctly. I've pushed a fix & now it's working for me.

PS You can update your installation with
raco pkg update pollen
or on Windows
"C:\Program Files\Racket\raco" pkg update pollen

Neat, thanks!

@mbutterick I haven’t used pollen in months but here I just updated to the latest version and I have a similar message I had before:

The application raised an exception with the message:

bytes->path: path string is empty

I did more testing. When I pass a path inside quotes like raco pollen start "C:\nAZERTY" I get the error up here. I need quotes for paths that have spaces in the terminal.

It also does not work when you have non-ASCII chars in your path, like e.g. é. Should it use strings instead of bytes or something?

After doing these two tests I renamed back to C:\nAZERTY and opened without quotes, got the same error when opening the server root (http://localhost:8080/) but it worked when opening the dashboard directly (http://localhost:8080/index.ptree).
So something is a bit weird with how it routes the root page?

Lastly, I’d expect the dashboard to follow the Windows path conventions.

Also if I click on the drive letter from the dashboard:

The application raised an exception with the message:

build-path: drive cannot be added to a base path
  drive: C:\
  base path: C:\nAZERTY

(same with absolute path instead of drive if I click on a path.)

What happens if you change your current directory to C:\nAZERTY and then do raco pollen start (without a directory argument)?

I pushed a possible fix. Let me know if it helps.

It works now except when opening server root (http://localhost:8080/), opening index.ptree or a file works properly.

(I hit this also with raw UTF8 files without BOM but it seems to be an issue on the browser’s side.)

Sometimes a page will hang and fail to load and give a spurious TCP error:

It seems to correspond to a timeout from the client but the underlying error might be elsewhere. Does it look like a Racket error rather than Pollen?

(Notice that non-ASCII chars are not output properly but since it’s a Racket-output error, I’m assuming that Racket itself does it wrong.)

You won't see anything at the server root (http://localhost:8080/) unless you put your own index.html there. (This is deliberate behavior.)

As for the TCP error, the stack trace doesn’t originate in Pollen code, so it looks like a Racket error.

As for the non-ASCII characters, that’s probably because the web page showing the error needs to be set to UTF-8 — I can fix that.

PS. Because of a recent update, you need to change the name of project-require.rkt to directory-require.rkt.

It makes sense, however I’d expect it to not error with a stack trace when index.html isn’t present?

The web error is fine (through it lacks a DOCTYPE like the dashboard did previously), it was in the Terminal.

Right, thanks!
