after I install the newest racket package on my linux servers I always need
to run raco pkg migrate to reinstall dependant packages. trouble is I can
never figure out the version name of the previous install. Is there a raco

I'm in the midst of writing a nice performance/stress testing harness for
racket.
To measure performance with a GC language, it is very important to be able
to log accurate GC occurrences, along with how long they take.
The debug log seems to really output what I need except maybe a call to

I've been using db.plt package and it has been working well for me.
Thanks to Ryan for making it.
I would like to store and retrieve some binary data in my postgres
databases. Unfortunatly db.plt says it doesn't support bytea types yet.
How likely or doable would it be to get support for byta[]
That was my mistake. I was using a bytea[] on my column definition and I
only need to use was bytea.
Thanks for the info and setting right.

What is a good way to get user defined exceptions, written inside of

Say I have an item table in a database and it has a unique 'name' column.

I see that there is an eof-evt that goes ready once an input port hits eof.
I am in need of an event for an input port, that is ready only when a
non-eof would be read from that port, and is never ready once an eof is hit.

Here is a paper about it in case you have not heard of it.

I am interested in implementing authentication via client browser
certificates with a racket webserver.
I have a small online store website that has both a public side, for
anybody, and a set of pages that are private for the management interface of
that website.
But I don't like the risk of only
much of a stretch as far as modifications to the open
ssl code goes. I'm still playing with the openssl package and learning how
it works.

however the browsers behave as if everything is working correctly. Sound
like a familiar issue to anyone?

I'd like to hook into it with a reader extension somehow but the reader
documentation seems a bit terse in that area.
Does anyone know of some good places to look in the source for guidance?

I'm trying to create an output port that wraps a set of foreign interface

The ffi has a bytes_writable function which tells how many bytes can be
written as well as a write_bytes function that does the writing.
In this case I need to poll with bytes_writable until it returns more than

My workaround which was conducive to the database architecture, was use a
view that exposes the uuid as text along with other related columns. Then
upon insert or update, a rewrite rule casts it back to the uuid type into
the actual backing table.

Is there a way to view the previous versions that were installed from raco

I always find myself trying to guess the previous version number after an
