Mountpaths indicate mount points of external devices. Files
located under such paths should not be removed on sync, because
they may have not been deleted, but are just inaccessible right now.
This makes sense in general, however it also avoids a race condition.
The dirscanner may finish before the filescanworkers for the files
run, this then signals the whole indexer has finished.
Add implicit AND booleans at the end.
This fixes a number of issues in LooqsQuery:
(1) A query like a b c p:(something) would fail, because
a b c get merged into one word. This happens at the end.
lonewords are special and do not become a token immediatly. So previous
logic to add implicit ANDs does not apply.
(2) Negations were also broken with lonewords.
(3) The TokenType enum fields were too narrow to be useful for the bitmask
Independent of that, add support for 'limit:'
The pointer becomes invalid as readablePathLocation falls out of scope,
and exile.h quits with an error.
This may indicate exile API sucks, so something to think about there.
Detect mime types, and for text/*, run the default text processor.
The added benefit is that we can now add plaintext files without extensions,
or many other text files (e. g. source code).
While f67a37bc21 indicated the last remaining code could stay,
it can't because there is a launch failure of SandboxedProcessor.
This has been revealed by the changes of the previous commit,
aa03d0a4920e.
Hence, the GUI will be untouched by exile. We only sandbox
the preview generation and the indexing trough IPC.
There was an off-by-one, the SandboxedProcessor was only passed
'process', not the path to the file.
No processor was found for 'process', thus 'nothingProcessor' was
returned. Therefore, we never sandboxed (because we never had
to process anything).
The sandboxing would have failed though, because we need to launch
QCoreApplication, not QApplication.
The CLI was never affected.
It was possible the text was getting too big. The GUI
was lagging for previews of some text files. The first
assumption was that we would only have a couple of hits,
which is unreasonable for large .txt files and common
words.
We only ever see a handful of previews, it makes no sense
to get all snippets. So just allow 7 snippets, that's it.
Also, just cut after 1000 chars no matter what.
