Windows (Semi-hosted environment): filename and network access
Open, WishlistPublic
Actions

Description

  • Filename

We have a regression by / -> \ with make_filename.

In rG962058f70486: Allow tilde expansion for the foo-program options., the tilde expansion support is added for the argument handling.

This change breaks use of semi-hosted environment. Namely, using Wine emulation for testing Windows binaries on GNU/Linux host.
Specifically, in the tests by gpgscm, initial setup fails because gpg-connect-agent cannot spawn gpg-agent any more.

Apparently, replacing / by \ changes the semantics (gpgrt_access function fails for \home\gniibe\build\mingw-i686\gnupg\agent\gpg-agent.exe).

  • Network access

Dirmngr check_inet_support doesn't work well on semi-hosted environment.

The executable is on Z: drive (Z:\home\gniibe\build\mingw-i686\gnupg\agent\gpg-agent.exe) in the emulated environment.
Perhaps, when the path is absolute path with /, it is interpreted as on the drive Z:.

Recall that on windows you have a current working directory per drive. Thus only LETTER:\foo is a full patch - or an UNC (\\SERVER\foo).

For my testing environment, I have this patch for now.

Then, it works well.
