shouldn't be extern -- compiler will ignore an extern storage class specifier if
you also initialize it. Maybe static? or move into an anonymous namespace. (more
below).

gcc actually emits a warning about this, but only when compiling for C (e.g. the
file is ".c" not ".cc") - weird.

[gab, 2013/04/24 20:24:59]

If I don't make it extern, I get:
error C2970: '`anonymous-namespace'::FirstRunMasterPrefsBrowserTestT' : template
parameter 'Text' : 'kImportDefault' : an expression involving objects with
internal linkage cannot be used as a non-type argument

This is already in an anonymous namespace.

[tapted, 2013/04/25 00:02:42]

Ah, drat. Where did I read that ~"static and anonymous namespaces are the same
except you can use things in anonymous namespaces for template arguments". This
seems to destroy that - neither gcc nor visual studio let this happen for me.

extern seems to be the workaround - good work on figuring that out! And it looks
like compilers in C++ mode are happy with that being on the definition.
Otherwise you could separate an extern declaration with a non-extern definition.

But I think the template type is in an anonymous namespace but not the string
constants? For me, it still works if the definition is in an anonymous
namespace, with the extern specifier. That might be an improvement (but probably
more of a nit ;).

[gab, 2013/04/25 18:50:00]

Feel free to try different things after this lands as part of the work to
re-enable for Linux/MacASAN, for now I think, as you seem to agree, that this is
fine.

Could it be picking up '/Library/Google Chrome Master Preferences' in the corp
image instead when the file doesn't exist?

[gab, 2013/04/24 20:24:59]

This comment belonged with the ImportBookmarksFile test above, the "file"
mentioned is the bookmarks file (clarified comment), the master pref file itself
will exist.
This test is only testing the fact that the file import was launched, not
whether it succeeded, so that's ok. Makes sense?
