ace-builds tar file releases contain same filenames with differing capitalization

[hartman]

Describe the bug

I noticed that at least the releases:

• https://codeload.github.com/ajaxorg/ace-builds/tar.gz/v1.37.1
• https://codeload.github.com/ajaxorg/ace-builds/tar.gz/v1.39.0

contain a file with the same name but with differing capitalization:

tar -tf v1.37.1 | grep hx
ace-builds-1.37.1/demo/kitchen-sink/docs/Haxe.hx
ace-builds-1.37.1/demo/kitchen-sink/docs/haxe.hx

Expected Behavior

The tar file should not contain two files with the same name and differing capitalization

Current Behavior

When you attempt to extract this file on file systems that are case preserving and case insensitive (for instance macOS), you get undefined behavior when extracting these tar files.

Generally, the later file in the manifest will override the earlier file, OR an error is thrown.

For instance, when extracting with PHPs extractTo() without allowing overwriting of files, you will have:

Error: Extraction from phar ".foreign/tmp/ace.tar" failed: Cannot extract "ace-builds-1.37.1/demo/kitchen-sink/docs/haxe.hx" to ".foreign/tmp/ace/ace-builds-1.37.1/demo/kitchen-sink/docs/haxe.hx", path already exists

but when using command line tar -xzvf, it will silenty overwrite.

Reproduction Steps

does not apply

Possible Solution

No response

Additional Information/Context

This seems to only happen for the ace-builds releases. The files inside the ace repo, the tar release of these files, only have ace-1.39.0/demo/kitchen-sink/docs/haxe.hx

Ace Version / Browser / OS / Keyboard layout

1.37.1, 1.39.0

Doesn't seem like a recent regression.

@nightwing do you happen to know why this happens in ace-builds logic?

It seems we only have a single example in https://github.com/ajaxorg/ace/blob/master/demo/kitchen-sink/docs/haxe.hx and then for some reason it's doubled in ace-builds bundle -> https://github.com/ajaxorg/ace-builds/blob/master/demo/kitchen-sink/docs/Haxe.hx and https://github.com/ajaxorg/ace-builds/blob/master/demo/kitchen-sink/docs/haxe.hx.

Same thing happens to https://github.com/ajaxorg/ace/blob/master/demo/kitchen-sink/docs/jack.jack and https://github.com/ajaxorg/ace/blob/master/demo/kitchen-sink/docs/nix.nix
