Summary: FileSearch requires a parent folder found at depth 0
Initial Comment:
While testing the <FileSearch> and <DirectorySearch> elements, I've discovered
what is either a bug, or a limitation, in WiX or MSI.
(Based on Rob's quote about the difficulty of working with AppSearch I think
it's most likely a bug in WiX. :)
It's a bit tricky to describe, but basically it has to do with the FileSearch
element needing two things:
- it must be in a DirectorySearch element that describes its parent folder
with an effective depth of 0; although the attribute can be higher it must be
found at level 0
- if that DirectorySearch has a parent DirectorySearch element, it must have
been found at an effective depth of 0 as well
For example:
Let's assume we have the following folder structure:
C:\Temp\a\b\c\d\e\f\
And inside that folder structure we have a file:
C:\Temp\a\b\c\d\e\f\foo.txt
This search will NOT work:
<Property Id="FOO_DOT_TEXT_0">
<DirectorySearch Depth='0' Id="dir_search_0" Path="C:\Temp\a" >
<FileSearch Id="file_search_0" Name="foo.txt" />
</DirectorySearch>
</Property>
This search will NOT work either:
<Property Id="FOO_DOT_TEXT_1">
<DirectorySearch Depth='0' Id="dir_search_1" Path="C:\Temp" >
<DirectorySearch Depth='8' Id="dir_search_2" Path="f" >
<FileSearch Id="file_search_1" Name="foo.txt" />
</DirectorySearch>
</DirectorySearch>
</Property>
This search will NOT work either:
<Property Id="FOO_DOT_TEXT_2">
<DirectorySearch Depth='0' Id="dir_search_5" Path="C:\Temp" >
<DirectorySearch Depth='5' Id="dir_search_6" Path="d" >
<DirectorySearch Depth='2' Id="dir_search_7" Path="f" >
<FileSearch Id="file_search_2" Name="foo.txt" />
</DirectorySearch>
</DirectorySearch>
</DirectorySearch>
</Property>
However, this search WILL work:
<Property Id="FOO_DOT_TEXT_3">
<DirectorySearch Depth='0' Id="dir_search_8" Path="C:\Temp" >
<DirectorySearch Depth='6' Id="dir_search_9" Path="e" >
<DirectorySearch Depth='0' Id="dir_search_10" Path="f" >
<FileSearch Id="file_search_3" Name="foo.txt" />
</DirectorySearch>
</DirectorySearch>
</DirectorySearch>
</Property>
One workaround I've found is to use two searches, like this:
<Property Id="FOLDER_F">
<DirectorySearch Depth='0' Id="dir_search_11" Path="C:\Temp" >
<DirectorySearch Depth='8' Id="dir_search_12" Path="f" />
</DirectorySearch>
</Property>
<Property Id="FOO_DOT_TEXT_4">
<DirectorySearch Depth='0' Id="dir_search_13" Path="[FOLDER_F]" >
<FileSearch Id="file_search_4" Name="foo.txt" />
</DirectorySearch>
</Property>
...which seems to work just fine so long as the properties are defined in the
correct order.
Is this a bug in WiX, or a limitation in MSI?
So to summarize, there are two possible bugs:
1. you can't recursively search for a file without specifying its parent folder
(the file must be found at an effective depth of 0)
2. you can't recursively search for the parent folder either (the file's parent
folder must also be found at an effective depth of 0)
