+# System.Formats.Tar.TestData
+
+This package contains test assets for the `System.Formats.Tar` assembly.
+
+## Script
+
+The files can be autogenerated with the `GenerateTarFiles.sh` script. This script needs to be executed in a Linux machine (preferably Ubuntu, since that's where it was tested). The OS should have the Unix `tar` tool available.
+
+The user executing this script must be part of the sudo group (but should _not_ execute the script with `sudo`).
+
+The script is executed without arguments. Make sure to mark the script as executable before executing it:
+
+```bash
+$ chmod +x GenerateTarFiles.sh
+$ ./GenerateTarFiles.sh
+```
+
+## Output
+
+The script generates uncompressed (`*.tar`) and compressed (`*.tar.gz`) files in all the supported formats: V7, Ustar, PAX and GNU.
+
+In the case of GNU, there are two variants supported by the Unix `tar` tool. We generate both, inside the `gnu` and `old_gnu` folders.
+
+In the case of PAX, the Unix `tar` tool can generate archives without and with a Global Extended Attributes entry at the beginning. For that, we generate files inside the `pax` and `pax_gea` folders, respectively.
+
+## Excluded unarchived files
+
+The final `*.nupkg` also includes the `unarchived` folder, which contains all the files that are expected to be found inside the `*.tar` and `*.tar.gz` files. But there are some file categories that are excluded because either NuGet or Visual Studio do not support them:
+
+- Files and directories with very long paths.
+- Hard links. They get packged by `*.nupkg` as regular files (this might be expected, since there is no way to differentiate between regular files or hard links).
+- Special files: Block device, character device, fifo.
+
+These files are generated by the script on the fly, archived with the `tar` tool, and then deleted at the end of the script execution to prevent getting them packed.
+
+## Expected metadata
+
+The script makes sure all the unarchived files are marked with the following metadata information before archiving them:
+
+- `uname`: `dotnet`
+- `gname`: `devdiv`
+- `uid`: `7913`
+- `gid`: `3579`
+- `mode`: `744` - This translates to u+rwx, g+r, o+r
+
+Device files get the following numbers:
+
+- Character devices:
+  - `devmajor`: `49`
+  - `devminor`: `86`
+- Block devices:
+  - `devmajor`: `71`
+  - `devminor`: `53`
+
+PAX files with a Global Extended Attribute entry at the beginning of the archive, get the following custom attribute added:
+
+`key`: `globexthdr.MyGlobalExtendedAttribute`
+`value`: `hello`
+
+## Consumption in dotnet/runtime
+
+When running tests, the "current directory" is the location where all these test assets can be found.
+
+To access an unarchived asset file:
+
+```cs
+string path = Path.Join(Directory.GetCurrentDirectory(), "unarchived", "file_hardlink", "file.txt");
+```
+
+To access a tar file:
+
+```cs
+string path = Path.Join(Directory.GetCurrentDirectory(), "tar", "pax_gea", "file_hardlink.tar");
+```
+
+To access a `tar.gz` file:
+
+```cs
+string path = Path.Join(Directory.GetCurrentDirectory(), "targz", "pax_gea", "file_hardlink.tar.gz");
+```
+
+## Test cases
+
+- `file`: Contains a regular file named `file.txt`
+- `file_hardlink`: Contains a regular file named `file.txt` and a hard link named `hardlink.txt` whose target is the `file.txt` inode.
+- `file_symlink`: Contains a regular file named `file.txt` and a symboliclink named `link.txt` whose target is `file.txt`.
+- `folder_file`: Contains a directory named `folder`, which contains a regular file named `file.txt`.
+- `folder_file_utf8`: Contains a directory named `földër` which contains a regular file named `áöñ.txt`.
+- `folder_subfolder_file`: Contains a directory named `parent`, which contains a directory named `child`, which contains a regular file named `file.txt`.
+- `foldersymlink_folder_subfolder_file`: Contains at the root a directory named `parent`, which contains a directory named `child`, which contains a regular file named `file.txt`, and at the root, it also contains a symbolic link named `childlink` that points to the `child` directory.
+- `many_small_files`: Contains 10 directories, named from `0` to `9`, and each directory contains 10 regular files, each file named `0.txt` to `9.txt`.
