spicerack's Issues

installing locally library with spicerack deps

lein install creates following warning:

OverlappingFileLockException when prematurely closed

After interrupting a process within an open-database, subsequent calls yield OverlappingFileLockException. I'm not sure how to release this lock since the database object is no longer in scope.

database as a resource in jar

The last concert before I go further. spicerack seems to work with the file. What if I want to include read-only database in the library bundled in the jar. Such files are later accessible via resource url. How to make it here?

`open-database()` creates DB paths without checking validity

And, ideally, opening a DB read-only should not attempt to mkdir.

Thanks!

Storing custom type

Do you know any way to store objects created by deftype or defrecord? (deftype with java.io.Serializable interface).

Add logo graphic.

read only access

Hi, first, thanks for making MapDB wrappings. I wasn't aware it exists.

Quick question: for read only access can I keep opened database around unless JVM is dead? Or should I everytime wrap into with-open? What is the proper strategy?

Opening and closing DB to access single value can be inefficient, however currently it's 6ms on my laptop which is perfectly ok.

Error when deserializing

It seems like MapDB allows storing things that it is unable to retrieve, thus rendering the database inaccessible.

I'm not 100% sure what I did here, but it would appear I stored an anonymous function.

Would it be possible to detect cases like these so the error happens when storing the value, rather than later on when retrieving it?
