Gatsby is sourcing READMEs

[fostimus]

I use gatsby-source-filesystem to take in markdown files for articles. It's limited by directory, e.g. content/blog-posts.

I'm using graphiql during development to see what gets sourced, and Gatsby is processing markdown files from the entire project, like my top-level README and directories I did not configured to be sourced.

Is this normal behavior? I've used the ignore option on gatsby-source-filesystem for READMEs, but that didn't work. How can I prevent these files from being sourced?

The sourcing must be set up somewhere, Gatsby doesn't automatically picks those files up. You can run this query to check with plugin and with path is sourcing the files:

{
  allFile {
    nodes {
      sourceInstanceName
      absolutePath
      internal {
        owner
      }
    }
  }
}

Seems like all files in the project are getting sourced via gatsby-source-filesystem. The files we don't have set up to be sourced have sourceInstanceName set to __PROGRAMMATIC__, what does that value mean?

This is still affecting us. I've tried using the ignore option and it still doesn't ignore the README.md files. Tried the following fileglobs:

**/README\\.md,
**/README.md,
README.md,
README\\.md,
**/readme-*\\.md,
**/readme-*.md,
readme-*\\.md,
readme-*.md,

__PROGRAMMATIC__ is likely used when the required name option is not set.

gatsby/packages/gatsby-source-filesystem/src/create-file-node.js

Line 70 in 89a3232

sourceInstanceName: pluginOptions.name || `__PROGRAMMATIC__`,

Could you share your gatsby-config.js or make a minimal reproduction? It usually doesn't occur (if I understand it correctly) and it's difficult for others to help with the provided information.

@gh640 I will try to get a minimal repro up, but likely don't have the time. Will come back here with one.

A hunch (if it helps) is that we use docz to generate documentation, which I know uses gatsby-source-mdx, and is horribly outdated. I could see a case where docz is grabbing all *.md(x) files in our repo.
