Ok, before we start changing these things back and forth: Anyone else who has an opinion on how M4 (server), M5 (server), SQL4, SQL5, XQuery(4) should reveal their version numbers at startup-/module-loading time, and whether the differences between M4 & M5 should/need to be increased by having different/non-aligned/"inconsistend" welcome messages?

[Monetdb-developers] [M5] RFC: function shipping semantics
by Fabian Groffen 13 Jul '07

13 Jul '07

Hi all, I'd like some input on an issue that I can't get a clear vision on for now. Recently I added the remote module in MonetDB 5 which basically has 3 functions which perform actions with a remote (MonetDB 5) server. The functions get, put and exec retrieve, store and execute an object from, to or on a remote host. get and put allow for retrieval and storage of basically any type, scalars, strings, BATs, etc. exec only executes functions available on the remote host. The idea is to have one to "put()" a function to the remote host, and then execute it, retrieving its return value. exec is currently implemented that way, however, get and put of functions is not because it is unclear to me how this should exactly happen. For the case of put() I can think of the following which seems quite intuitive and ok to me: function user.func(v:int):str; r := "something"; return(r); end func; m := remote.put("host", "user.func(:int):str"); t := 5; q := remote.exec("host", m, t); io.print(q); The example puts function func to the remote host and executes it with argument t which is 5. The return string kept in q will contain the string "something". Because the identifier of the function on the remote host is returned and assigned to m, the function can easily be executed, since exec requires the function name as string. Currently that function name is just the function without its signature. The signature (which is not required, even not desired currently) can be deduced from the arguments given, resulting in a normal function resolution and (slightly misleading) error reporting if that fails. The other way around (thus to get a remote function) is still unclear to me how to do it. I could imagine the following that should work: v := remote.get("host", m); w := remote.get("host", "user.func(:int):str"); Problem with v is that m is not a full signature, so a conflict may arise if m is overloaded. This is not necessarily a problem, since m is a unique identifier, so no overloading for it exists. However, it is a requirement that a get after a put should always succeed and result in the same object that was put. The bigger problem here, however, is how to deal with the function being get. Since a function cannot be stored in a variable in MAL, it has to be stored on the local machine, or its contents as a string returned. In the first case the get() function would return its local identifier. In the latter case it would return a (big) string. In both cases, the function cannot be "used" as function in the program. A variable containing a function name cannot be used as in e.g.: k := v(t); where v, a variable, would be used as function, "dereferencing" v's value or something. Of course with a human factor one can do: io.print(v); and use the value of v to construct a call to the locally stored function. In the case of a string, the function has to be made, which I don't know how to do that, but would give explicit control over its name to the program. I don't think the concept of eval is clearing up things, as well as possible at all (if you think about the k := statement where only v should be expanded, not t neither k). Ideas?

Yes, the default is the user module. I have been 'struggling' with arguments for reflective functions. I settled down to using two arguments where needed e.g. f(mod:str,fcn:str,...) It is not optimal, but avoid string construction/analysis

[Monetdb-developers] build problem for java jdbc driver
by Frans Verster 23 Jun '07

Hi monetdb-developers, I just build the MonetDB-Venus-SuperBall-SR1, the build of the c code went ok (nice!) except for the java jdbc driver I do find checking for javac itself in the build log but not the actual use of it. Do i build correctly? /var/tmp/MonetDB-1182546749/log : Fri Jun 22 23:12:29 CEST 2007 called with arguments: --prefix=/tmp/frans/MonetDB --enable-sql --enable-xquery Calling javac (1.6.0) with all/most files does not help: javac nl/cwi/monetdb/jdbc/*.java nl/cwi/monetdb/jdbc/MonetDataSource.java:57: cannot find symbol symbol : class MonetDriver location: class nl.cwi.monetdb.jdbc.MonetDataSource private MonetDriver driver; ^ etc... The only file with that name is /var/tmp/MonetDB-1182546749/MonetDB-client/clients/src/java/src/nl/cwi/monetdb/jdbc/MonetDriver.java.in but renaming doesnt help. and for an other file: nl/cwi/monetdb/jdbc/MonetClob.java:35: nl.cwi.monetdb.jdbc.MonetClob is not abstract and does not override abstract method getCharacterStream(long,long) in java.sql.Clob public class MonetClob implements Clob { ^ Did the jdbc changed with java 1.6, is the code compatible? Howto proceed? Thanks in advance Frans Verster
