Note that the interface is still a work in progress and might change
while still keeping the same interface version. This is going to be true
until the first stable release of this project (non beta).
This also adds a public dependency to machinery in the header-only
backend project. This is because the backend does need functionality
from machinery, such as FileRecordData and TigerHash.
Newer versions of gcc have a small string optimizations that makes
moving FileRecordData objects behave incorrectly. When a small string is
moved, string_refs into it become invalid. Making a path on the fly
using the path() method also has the side effect of making
FileRecordData smaller in size.
This saves having to remember to do STRING(TOUPPER) in every cmake file.
At times that's really not convenient if possible at all.
For example when a top-level project is guessing what option some
subproject is going to use and tries to use it for the builtin options
view. The acutal OPTION statement is not there, and it's not nice to put
a string(toupper) on a variable that seems to come from nowhere (and in
fact it might not be there at all).
This ends the scantask refactoring. It is now possible to scan
directories using the new system. Progress feedback is made
available again, although it could use some improvements.
This was needed so that machinery wouldn't depend on common.
Also moved compatibility.h to helpers include dir.
Ideally mediatypes.hpp will be merged into mediatype.hpp, or there
will be some kind of renaming because the two names are
getting really confusing.
Fixes a crash due to an assertion trying to access a
past-the-end iterator.
Gets content type detection to work, although only after
hashing is done (see comment in main.cpp for details).
Fixes a problem with the array passed to guess_content_type
being not sorted as the function expects.
Adds more assertions.
