I suspect there's only one automated builder in existence for GnuCash on
Windows, and that's our own build server. So I'll focus on this one only.
For this builder we have a set of scripts that wrap around the actual
install script.
As it happens these scripts already run svn update to get the latest
build sources in daily_build.sh and weekly_build.sh. This scripts
consisting of about 5 lines of code. So theoretically the risk of
invalidating the build script due to the update is here as well.
As the automated builder runs on Windows, there's an additional twist here
that I haven't seen mentioned: On Windows, the OS will refuse to change a file
that's currently "in use" by the current process. That is, a script file that
runs "svn update" (or git pull) by definition is "in use", and its svn/git
child process will be refused to change this very script file. Essentially, if
the script runs an update that will change itself, the update will fail with
some very weird error message because of this.
Hence, the "invalidation" of the script file might be one issue, but
Windows' refusal to change the currently active script file is
another. Because of this, the main update/pull of the working copy
needs to be somewhere else than the actual script file. At least
that's my understanding of this.
The one that matters most, I believe, is the "gnucash.bat". Luckily
that one doesn't update frequently, so I think we can manually update
that as necessary. But yes, I do believe we have hit this issue before.
It's not "gnucash.bat". It's in the scripts that are called by
"daily_build.bat". Those can be:
daily_build.sh
daily_build_git.sh
weekly_build.sh
weekly_build_git.sh
build_tags.sh
build_tags_git.sh
I have added a comment in each of these files to remind us of this
Windows restriction. Thanks for bringing it up again.
