announce: system-check (beta)
Tuesday, June 6, 2006

Enterprise Lisp has been rumbling and grumbling slowly to life around me. Today I'm announcing the first beta of System-check, an asdf-upgrade like facility, that will eventually integrate with an improved ASDF-Install-tester and other cool things. The idea behind system-check is that it's easier to centralize the testing of Lisp libraries that it is to get all of the library developers to agree on versioning schemes and the like. Therefore Enterprise Lisp will regularly check on all ASDF installable systems and

  • make sure the system can be downloaded,
  • make sure that the GPG signature can be retrieved,
  • make sure that the signature file is valid,
  • make sure that the tar archive can be decompressed and
  • that the archive contains a valid system definition
  • that can be properly loaded into a lisp system

This will be coupled with an improved and distributed ASDF-Install-tester that can go on to make sure that systems actually do install on a variety of Lisps and environments.

System-Check is the client that you can run to see if your systems are up to date. Here is an example session (in OpenMCL). First, we load system-check. It displays instructions when it finishes loading:

? (asdf:oos 'asdf:load-op 'system-check)
; loading system definition from user-home:darcs;asdf-systems;system-check.asd.newest into #<Package "ASDF0">


----------------------------------------------------------------------
;; System-check helps keep your ASDF-Installable systems up to date 
;; by communicating with enterpriselisp.com via HTTP. Enterprise Lisp 
;; checks ASDF-Installable systems regularly to make sure that they 
;; work properly and install correctly.  
;; 
;; System-check has three main entry 
;; 
;; 1. update - checks all of your ASDF-Installed systems against the 
;; most recent available version and lets you select which ones to 
;; 
;; 2. gather - performs the same check as update but returns the 
;; results as a 
;; 
;; 3. check-system - performs a check on a single 
;; 
;; More information can be found in the documentation or at 
;; 
;; System-check can look for systems in several different 
;; 
;; * installed-systems (used by default) - returns a list of systems 
;; that seem to have been ASDF installed (see its documentation for 
;; 
;; * installable-systems - returns a list of all of the available 
;; systems (using 
;; 
;; Both of these functions take the keyword argument 
;; :only-asdf-installable?. If this is true, then System-check will 
;; query the CLiki to see if the system is ASDF installable.  
;; 

We cut to the chase and call the update function.

Now that we've seen the report, we're asked what we want to update and ASDF-Install takes away the show.

We'll now ask which kinds of systems you want to update. 
You will be able to confirm before the update process 
begins.

11 systems need to be updated. Do you want to update them? (y or n)  y

Marking these systems for update: araneida, asdf-system-connections, cl-html-parse, cl-mathstats, cl-variates, lift, metabang-bind, metacopy, moptilities, tinaa, trivial-http.

6 systems are changed locally and remotely. Do you want to update them? (y or n)  n

System-check and the Enterprise Lisp system checker are both in beta at the moment. I've tested on several lisps but expect that problems and edge cases remain. Please let me know if you try system-check and it fails. I'm also working on some improvements to ASDF-Install so that it can behave more reasonably when installing multiple systems and with improving the back and forth between the client and the server. Enterprise Lisp is all about making Lisp easier for everyone, so please let me know if anything seems awry.
