Linux binary releases as ZIP lose executable permissions

[nh2]

Hi, the ZIP releases lik sieve-0.5.3-linux-x64.zip on https://github.com/thsmi/sieve/releases/tag/0.5.3 are not very useful to Linux users because ZIP cannot carry file permissions, so if you try to run it you get:

$ ./sieve 
zsh: permission denied: ./sieve

If one try to fix it it still fails because other files don't have the right permisisons:

$ chmod +x sieve 
$ ./sieve 
zsh: no such file or directory: ./sieve

Could you switch to .tar.gz or a similar format that keeps executable permissions (chmod +x bits)?

Thanks!

well, the original zip format from 1989 could not store permission bits. But this changed in the more than two decades ago when the "extra field" was introduced. In the "extra field" you specify the information as operating system and data pairs. This means you can embed native DOS, NT as well as UNIX file modes at the same time. Most zip packagers typically include native UNIX file mode mappings for better compatibility.

The packaging script also adds UNIX file modes to each zip file entry:

But this meta information, is accidentally overwritten at a later stage, by an incorrect wildcard match.
The pull request attached to this issue fixes this. The 7zip screenshot shows the "sieve" file has an UNIX "extra field" which carries now the correct UNIX file mode.

But I would suggest to use the app image, if you are on Linux. All you need to do is, downloading the file, then chmod the download and you are done. No need for unzipping, because everything is contained in a single file.

Thanks! Happy to check it for the next release.
