packaging: say what really happens when the program is running during an upgrade

[donislawdev]

The packages from #143 were installed, run, upgraded and removed on Windows Server 2025 before anything is submitted. Two sentences they carried were not what happens, and this puts the measured behaviour in their place.

What was measured, with the window open

	upgrade	uninstall
Chocolatey	exit 0, new version installed, the running copy keeps working from lib-bkp and stays there until the next Chocolatey operation on the package	exit 0, shortcut, shim and folder removed, the running copy stays in lib-bkp for good
WinGet (machine scope)	fails with 0x8a150003 "Access is denied" on tfg-gui.exe, after deleting LICENSE and README.md. Run again with the window closed, it succeeds in 4 s and the folder is whole	not measured with the window open

What changes

• chocolateybeforemodify.ps1 said the operation would not succeed while the program runs. It does succeed. The warning now says Chocolatey goes ahead and names the folder the running copy is left in. Measured again with the new text: the path it prints is the path the copy is in.
• Both WinGet descriptions say to upgrade when the program is not running. A portable package carries no script, so the description is the only place a person can read it first.
• packaging/README.md describes both feeds as measured, and names microsoft/winget-cli#6160: WinGet leaves the package folder on PATH after an uninstall, for every package that sets ArchiveBinariesDependOnPath. Reproduced here with WinGet 1.29.380 on a clean install and uninstall.

Also measured, and fine

• Chocolatey: the window shim returns the terminal in 0.1 s, the window runs the real program rather than the shim, and it opens from the Start menu shortcut.
• WinGet: each program on PATH exactly once, no link made, opengl32.dll not in a folder on PATH.
• Started with --software-gl, the window loads libgallium_wgl.dll and opengl32.dll from the opengl folder of the installed package, through WinGet and through the Chocolatey shim alike.

Checked here

• The packaging guards, and the cheap gates across the tree: 83 of 83.
• Both WinGet manifests pass winget validate with the longer descriptions, and the changed script parses in Windows PowerShell 5.1.

Summary by CodeRabbit

• Documentation

  • Clarified that WinGet may leave the package folder on PATH after uninstall.
  • Added feed-specific guidance for upgrades while the program is running: WinGet upgrades may fail partway with an access error, while Chocolatey proceeds and may leave the running copy in a backup folder.

• Bug Fixes

  • Added upgrade warnings for the CLI and desktop app. Avoid upgrading the CLI during a tfg run; close the desktop app before upgrading with WinGet.
  • Chocolatey warnings now explain where a running copy is left and may need cleanup.

📝 Walkthrough

Walkthrough

The package descriptions and packaging documentation now describe observed WinGet and Chocolatey behavior during upgrades and uninstalls. The Chocolatey pre-modification warning identifies the lib-bkp folder that may contain a running copy.

Changes

Packaging guidance

Layer / File(s)	Summary
Chocolatey running-process handling .github/scripts/build_packages.py, packaging/README.md, packaging/chocolatey/tools/chocolateybeforemodify.ps1.in	The script warns that Chocolatey may leave a running copy in lib-bkp. The README describes observed behavior for Chocolatey and WinGet during upgrades and uninstalls.
Package descriptions and WinGet documentation .github/scripts/build_packages.py, packaging/README.md	WinGet package descriptions warn about upgrading while programs are running. The README states that the package folder remains on PATH after uninstall.

Suggested labels: packaging

Merge Risk: 🔵 Low · up to 04011

Users may mistake one PATH report and one desktop-upgrade measurement for universal WinGet behavior. Correcting the wording is straightforward, and the remaining risk is limited to packaging guidance.

Review details

Systems and components

• observed — packaging (service) was modified; 2 changed files map to changed impact.

Before / after behavior

• observed — Modified behavior in packaging/README.md: The WinGet description now documents that the package folder remains on PATH after uninstall, links the open issue, and records the observed result with WinGet 1.29.380.
• observed — Modified behavior in packaging/README.md: Replaces the general statement that chocolateybeforemodify.ps1 warns when the program is running with measured, feed-specific behavior. Chocolatey proceeds successfully with upgrades and uninstalls, moving the running copy to lib-bkp; that copy remains until a later package operation after upgrade, or indefinitely after uninstall, and the script names it for later deletion. WinGet upgrades fail with “Access is denied” after deleting some other files; the package works again after retrying with the window closed, and its description carries the warning.
• observed — Modified behavior in packaging/chocolatey/tools/chocolateybeforemodify.ps1.in: The comments replace the claim that Windows prevents replacement and the operation complains with a description of Chocolatey proceeding, moving the package to lib-bkp, and potentially leaving the running copy there; they also correct the earlier statement that the operation fails.
• observed — Modified behavior in packaging/chocolatey/tools/chocolateybeforemodify.ps1.in: When a matching process is running, the script now constructs the lib-bkp\<CHOCO_ID> location and warns that Chocolatey proceeds but cannot delete the running copy, naming the folder to remove after closing the program. This replaces the instruction to close the program before upgrading or uninstalling.

Full details: Clear User-Facing Text

Explanation

The new WinGet CLI description says “no tfg run is in progress,” but the actual user-facing command is tfg generate; the command table has no run command, and the README documents tfg generate. This names the same operation differently and can direct users to a nonexistent command.

- Around line 101-102: Update the WinGet warning in the package-description
logic in build_packages.py: remove the `feed == "winget"` warning that claims an
active `tfg run` prevents upgrades, and qualify the desktop-package warning to
the measured Windows Server 2025 and WinGet 1.29.380 scenario, including the
observed failure and recovery behavior. Do not make a general claim about WinGet
replacing running programs.

In `@packaging/README.md`:
- Line 40: Update the README claim linked to microsoft/winget-cli#6160 to
describe it as a report about VovSoft.3DBoxMaker on WinGet 1.28.220, not as
evidence that all packages setting ArchiveBinariesDependOnPath behave this way.

1.29.380.

microsoft winget-cli issue 6160 ArchiveBinariesDependOnPath reproduction package version

💡 Result:

Issue **`#6160`** uses **VovSoft.3DBoxMaker** to reproduce the problem:

1. Install it with `winget install VovSoft.3DBoxMaker --installer-type portable`.
2. Check the user PATH in `sysdm.cpl`.
3. Uninstall with `winget uninstall VovSoft.3DBoxMaker`.
4. The PATH entry remains.

The reported WinGet package version is **Microsoft.DesktopAppInstaller 1.28.220.0** (WinGet CLI 1.28.220). [1]

---

Scope the WinGet PATH claim to the measured package and version.

Line 40 presents issue #6160 as evidence that every package setting ArchiveBinariesDependOnPath leaves a PATH entry after uninstall. The issue reports one reproduction for VovSoft.3DBoxMaker on WinGet 1.28.220. Limit the README claim to the package measured here with WinGet 1.29.380, and describe issue #6160 as a report.

Measured here with WinGet 1.29.380: the entry stays, pointing at a folder that no longer exists.
