Feature #1931

Updated by Matthieu Decorde almost 3 years ago

During TXM post-installation, System.getProperty("user.home") may point to a wrong directory (can't read, write, does not exist)

h3. Solution 1

- First build the user home directory to use in TXM.bat :
- call TXM launcher with the "-Duser.home=<user home>" option or with "set _JAVA_OPTIONS=-Duser.home=%HOMEDRIVE%%HOMEPATH%"

**user home**

Notre hypoth├Ęse courante est la suivante (see https://groupes.renater.fr/wiki/txm-info/public/documentation/documentation_c#file_utilities) :
* USERPROFILE = HOMEDRIVE + HOMEPATH (local profile)
* HOMESHARE = HOMEDRIVE + HOMEPATH (roaming profile)

So we'll use HOMEDRIVE + HOMEPATH as user home directory.

h3. Solution 2

II) add a test at the beginning of the post-installation, if it is not possible to create the TXM user directory then ask the user a directory with write access where the TXM user directory will be created.

Dialog:
title: TXM user directory installation
content: TXM can't create the TXM user directory in "C:/Users/stud". Please select another directory.
[ ] [...] -> open DirectoryDialog
[Cancel] -> abort post-installation and quit TXM?
[OK] -> Continue the installation, ask again if the new directory is not ok

h3. Solution 3

If the user unplug the network (cable/wifi) or if the roaming profile is not reachable, the HOMEDRIVE+HOMEPATH path point to nothing and TXM can't start.

Add an existing directory test in the TXM.bar script and use the local profile.

If the local profile is also not usable (read&write rights), abort TXM launch.
