Autoupdate is overwriting unpublished 0.0.1-beta.10 with published 0.0.1-beta.9

[semireg]

• Version: 20.28.4

• electron-updater: 3.1.2

• Target: Mac

I've published version 0.0.1-beta.1 through 0.0.1-beta.9 of my app. Before publishing 0.0.1-beta.10 I launched and it found and tried to install 0.0.1-beta.9. Is this expected behavior?

Looking at isUpdateAvailable it seems getVersionPreleaseComponents (semver.prerelease) parses "beta.9" into an array consisting of ["beta", 9]. The equality check fails and the method falls through to return default true.

The more I read about semver and prerelease tags the more confused I am. When a channel is assigned via autoUpdater.channel = 'beta' it is hitting the update file beta-mac.yml. However, when it's comparing these prerelease components... shouldn't it instead be comparing the channel (1st element)?

if (currentVersionPrereleaseComponent === latestVersionPrereleaseComponent) {
      // allowDowngrade taken in account only if channel differs
      return isLatestVersionNewer
}

should be something like...

    const currentChannel = currentVersionPrereleaseComponent[0]
    const latestChannel = latestVersionPrereleaseComponent[0]

    if (currentChannel === latestChannel) {
      // allowDowngrade taken in account only if channel differs
      return isLatestVersionNewer
    }

I forked the repo and committed this quick test/fix.

I'm unsure how to test this, though. The electron-builder repo contains many other NPM packages... what is the npm command or package.json format to install electron-updater from a different repo?

This doesn't work:

    "electron-updater": "https://github.com/semireg/electron-builder/tree/semireg-beta-build-num/packages/electron-updater",

I've also tried:

    "electron-updater": "file:../electron-builder/packages/electron-updater",

and then run npm run compile within ../electron-builder and npm install within ../electron-builder/packages/electron-updater.

However, then I get this error when trying to npm install in my electron project:

Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3".

I've spent a few hours trying to update babel to 7, but I'm having all sorts of issues. 👎
