Emmanuel Lecharny commented on DIRSERVER-604:
---------------------------------------------
Well, the (a) is possible, but a little bit overkilling. We are supposed to
send data to the server which will check their sanity against the schema
internally. Of course, as we are connected to the server, we could ask for the
schema.
The (b) seems to be a better soltion. However, just keep in mind that when
importing files, you are supposed to put them into binary data (like
jpegPhoto). I don't know if it makes sense to inject text into an attribute
like 'givename' or 'description'. I guess that the initial intent of G. Good
was to support a kind of ldap BLOB, so the data are supposed to be binary.
I must admit that I suffered from this UTF-8/ISO8859-1 format when injecting
data into a ldap server, so your idea seems to be a good solution. I have added
a method to deal with imported files that could take an encoding as a parameter
(it was not committed), so we can easily extended the :< operation the way you
suggested.
Last thing, remember that in any case, attributes are always stored as byte[],
not as UTF-8 Strings, except if the schema tells that the attributeType is not
binary. Here is the transformations applied to an attribute value if you send
it through a Ldap client :
initial data ASN.1 ASN.1 Storage
encoding decoding
UTF-8 ------> byte[] -----------> byte[] ---------> if attributeType is
binary, byte[], String(UTF-8) otherwise
binary ------> byte[] -----------> byte[] ---------> if attributeType is
binary, byte[], String(UTF-8) otherwise
So if the file contains binary data, it will *not* be transformed in any case,
except if you fill a textual attributeType.
