server doesn't run (libcrypto error, etc)

[vegashacker]

Reported via email:

The server doesn't run: when I tried running the script (after fixing the path to the binary), first I got this:

default-load-handler: cannot open input file:
"/home/marek/.plt-scheme/planet/300/4.1.1/cache/untyped/mirrors.plt/1/3/doc/mirrors.scrbl" (No such file or directory; errno=2)

I couldn't reproduce this so far, but now I'm getting this:

ffi-lib: couldn't open "libcrypto.so" (libcrypto.so: cannot open shared object file: No such file or directory)

libcrypto.so is part of libssl-dev in Debian and most likely not installed on most computers. What is available is libcrypto.so.0.9.8 from the libssl0.9.8 package, which has a wide installation base since it is a central part of the SSL ecosystem.

The first issue may just be a PLaneT cache-related upgrade thing. I've experienced similar issues when upgrading to new versions of PLT Scheme. Sometimes I find it helpful just to remove my planet cache entirely.

This thread seems very relevant to the second issue:  http://www.cs.brown.edu/pipermail/plt-scheme/2007-February/016356.html

LeftParen? uses digest.plt in user.scm to do md5 hashes.

Since md5 us only used to calculate the digest of a short string (password + salt),
maybe the simplest solution is to use the builtin md5 routine which is written in Scheme
(and thus does not rely on any external library)?

I resolved this issue by removing the dependency on the digest library, as per soegaard's suggestion. Here's the patch:

I'll resolve this ticket when I do the next PLaneT release.

LeftParen? 0.4 (version (3 0) on PLaneT) is out, and this bug is fixed in it.
