ipfs.files.cat() no longer finds index.html files in directories

Type: Bug

Severity: High

Description:

In previous versions of js-ipfs (0.27.2 for instance), you could ipfs.files.cat() a web page "directory" path stored on IPFS, and it would retrieve any index.html page stored there. For instance, see this page on the gateway an example: https://gateway.ipfs.io/ipfs/QmTeW79w7QQ6Npa3b1d5tANreCDxF2iDaAPsDvW6KtLmfB/docs/examples/

In newer versions of js-ipfs (0.27.4 and 0.27.5), cat()ing such a path results in Error: No such file. I imagine this is a regression introduced by 120d291

Steps to reproduce the error:

Save this example repro index.html file, and then open it in your browser: https://gist.githubusercontent.com/witten/00f9eda2272a48f5f3ee602e09596e46/raw/3da247b9825e01b3bc836af3bb896c3f945069f8/index.html

Open your browser console and observe the Error: No such file. It may take a few second to load the first time.

Then, edit the file and change the first <script src> from https://unpkg.com/ipfs/dist/index.js to https://unpkg.com/ipfs@0.27.3/dist/index.js. Reload the page, and note that by rolling back the js-ipfs version, you've "fixed" the regression, and the HTML of the page in question spews to the console.

@witten that "feature" was actually a bug that got fixed. A files.cat should not pick up on an index.html, you will need to check it directly.

Ah, okay. Thanks for clarifying!
