Path handling error [edge case] permissions error while scanning files/directories when running --serve on a site generated into a folder in the parent folder where the parent folder has other files/folders in it

Open aral opened this issue 5 years ago • 0 comments

Eleventy’s server (--serve) fails to launch when --input is the current directory and --output is a directory in the parent directory. (Compilation – i.e., write() – and --watch succeed.)

Similar to #939, but, in this particular instance, the failure (see debug log) appears to be because scandir is trying to scan all the folders in the parent directory and it doesn’t have privileges to do so. I tried to reproduce it by creating files/folders in the parent directory owned by root but that didn’t trigger the error.

Not sure what it it is specifically about the files mentioned in the debug log that’s causing it to fail in this instance but here’s what a couple of them look like:

sudo ls -la /home/aral/sandbox/gnomit-test-build/var/run/cryptsetup
total 0
drwx------  2 root root   40 Feb 11 11:42 .
drwxr-xr-x 39 root root 1100 Feb 15 11:46 ..

sudo ls -la /home/aral/sandbox/gnomit-test-build/var/run/gdm3      
total 0
drwx--x--x  3 root gdm    60 Feb 11 11:42 .
drwxr-xr-x 39 root root 1100 Feb 15 11:46 ..
drwx------  2 gdm  gdm    40 Feb 11 11:42 greeter

Regardless, Eleventy shouldn’t be scanning the parent directory or subdirectories of the parent directory in any case. It should only be operating in ./ and ../eleventy-base-blog/.

To Reproduce

This reproduces it on my machine but you will not be able to without the troublesome files listed in the debug output. I tried zipping them up to include here but tar also failed on them.

Install Eleventy.
```
npm i -g @11ty/eleventy`
```

Clone the base blog example.

git clone https://github.com/11ty/eleventy-base-blog.git

Change to the base blog example’s directory and install its dependencies
```
 cd eleventy-base-blog
 npm i
```

Run Eleventy.

eleventy --input=. --output=../eleventy-base-blog-site

What should happen

Eleventy should compile the source in ./ and output it to /.eleventy-base-blog-site.

What actually happens

The following error is triggered (compiler output truncated; full debug output at end):
