+1 for naming the undo add button in a way that reflects the potential
data loss:
The user might not be happy when a file he has worked on for days
suddenly disappears (as happened a collegue of mine today).
>As long as you have the recycle bin enabled then the modified file
>goes there, just as it does for any other revert operation.
That might be true. But the user might not know that. The recycle bin
might not work on all types of media subversion will -
and even worse: there is always the possibility the file might just not
appear there even if there don't seem to be any reasons for this to
happen. In the case of my collegue
- the file was on the local hard drive,
- the recycle bin did contain several files that had recently been
deleted from the windows explorer
- and the "Use recycle bin when reverting" was checked in his settings
dialogue.
The problem might not even be completely tsvn's fault:
- Working in a corporate environment we have a virus scanner that
checks every file every time it is changed. But I assume using a virus
scanner and setting it up in a way that it reads files on
creation/modification to be a fairly typical use case. TSVN actually
contains code to retry some file moves after a short wait in this case.
- And windows doesn't seem to allow programs to move files while they
are still being read by a different process.
Don't know if that could be the case. If not I at least can include a
description how the problem was triggered:
1.) My collegue wrote a long report
2.) When he tried to commit it there was a tree conflict (the directory
had been renamed by somebody else)
3.) To clean up he did try to undo the add before moving it away and
adding it to the renamed directory trusting svn from long experience
that this program is designed in a way that it cannot possibly loose
data.
4.) The file disappeared, but didn't appear in the recycle bin.
The windows system was a 64-bit Windows 7 with TSVN 1.8.5
Kind regards,
Gunter.
