window: offer the home folder when started from the program's own folder or a disk root - #146
Conversation
…der or a disk root Started from Finder, macOS runs an application in "/", which is read only, so the window offered /tfg-out and the first run was refused by the system. Started by a double click, or from a shortcut, in the folder the program lives in, it offered a tfg-out folder there - refused under Program Files, and at risk in a package manager's folder. An MSI shortcut cannot start the window in %USERPROFILE% (Windows Installer expands it at install time, for the installing account), so the program decides instead. OfferedDirectory compares the working directory with the program's own by asking the file system (os.SameFile), not by text. A remembered tfg-out left under either place by the old offer counts as nothing remembered. A terminal and the command line are unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

rule: disk-root or program-directory working directories are redirected, while

Keep the directory-selection guards active without symlink support.
If a test host rejects symlink creation and has case-sensitive paths, anotherSpelling skips both tests. That also skips their disk-root and ordinary-directory cases. Use a distinct spelling such as dir + string(filepath.Separator) + "." as a fallback, and retain the sameDirectoryHere assertion. As per path instructions, tests must not use “a skip that hides a failure.”

…elog says where rather than how Outside review of #146. The changelog and the comment said a terminal keeps the old offer - the rule asks where the program was started, not how, so a terminal standing in the program's folder gets the home folder too. A guard now opens the window from the test binary's own directory and from the root of a disk and reads every box, and a remembered folder under the program's directory is checked through the window as well. A system with no second spelling of a directory skips that one case instead of the whole guard. A remembered bare tfg-out keeps counting as nothing remembered, on purpose, and a case pins it.

The window offered a folder it could not, or should not, write into in two situations. Both were measured before any code changed.
What was wrong
open) gets/as its working directory, even when the caller stood somewhere else./is read only:mkdir: /tfg-out-probe: Read-only file system. So the window offered/tfg-out, and the first run ended in a refusal from the system. Every macOS release so far does this. It went unnoticed because the Mac was only ever used from a terminal.tfg-outis refused, and in a package manager's folder the files sit where the manager may clear them at the next upgrade.The planned MSI cannot work around this with its shortcut: Windows Installer expands
%USERPROFILE%in a shortcut's working directory at install time, for the installing account, so any other account would be sent into someone else's profile (measured on Windows Server 2025 by reading the bytes of the.lnk). So the program decides instead.What changes
OfferedDirectory(working, program, home): when the working directory is the program's own directory or the root of a disk, the window offerstfg-outin the home directory. Anywhere else, as from a terminal, nothing changes. The command line is unchanged.os.SameFile), not by text, so letter case, short 8.3 names and links do not matter.LeftByTheOldOffer: closing the window records whatever the box held, so a window once started from Finder remembers/tfg-out. A rememberedtfg-outunder the program's own directory or under a disk root now counts as nothing remembered.internal/gui/window/offered.go).startingDirectoryonly gathers the three inputs from the system.A double click in an unpacked zip now offers the home folder too, instead of a
tfg-outnext to the program. One rule for every way of starting it, and deleting an old unpacked folder at upgrade no longer deletes results.Checked here
internal/guard/offereddirectory_test.go. The own-directory case uses a second spelling of the same directory (a link, or letter case where links are not allowed) and assertsos.SameFilebefore trusting it. Also covered: a disk root, anywhere else, no home directory, the remembered value, and the window really passing over it at start.go vet,gofmtandgolangci-lintreport nothing....\home\tfg-out. The control, started from another folder, said...\elsewhere\tfg-out.Not checked: the real window on macOS after the change (the root rule is guarded and the
/working directory was measured), and Linux started from a file manager.🤖 Generated with Claude Code
