bcfg-server/Packages should be more verbose

Description

...especially in verbose mode.

When I restarted my not-daemonized 1.0.1 server after the weekend, I assumed it would have to update the packages list and that that would take a moment, but that is because I already know this procedure.

If I didn't know the software, behavior like this:

chaos:~ # bcfg2-server -dv
(...45 minutes of nothing but high memory and cpu usage...)
Packages: File read failed; falling back to file download
Packages: Updating http://firstrepo[...]
(...60 minutes more waiting...)
Packages: Updating http://secondrepo[...]
Loading experimental plugin(s): Packages
[...]

...would make me assume something is wrong and I would have (p)kill -9'ed the process after two minutes.

This would most likely be much faster on "normal" machines since this is a VM with few resources (2GHz CPU, 256MB RAM), but adding and informal message before updating the package lists shouldn't hurt at all. (Make the server a bit less of a black box (; ...)

What's probably worse, client connections during this time aren't possible:

client:~ # bcfg2 -enqv
Server failure: [Errno 8] _ssl.c:482: EOF occurred in violation of protocol
Failed to download probes from bcfg2
[Errno 8] _ssl.c:482: EOF occurred in violation of protocol
client:~ #

Wouldn't it be possible to "cache" the old version of the repodata and fetch the updates in the background, allowing clients to contact the server during this time?

  • Status changed from new to closed
  • Resolution set to wontfix

We used to serve configurations before we had the repo fully loaded, which led to all sorts of problems. Due to the way that we update the data structures, i don't think it would be robust. Also, at this point in the server, the startup is synchronous, so changing that would be dicey.

As a workaround, this operation can be performed out of line with a server restart by using bcfg2-info instead. (basically, remove the cache, start up bcfg2-info, wait however long it takes, then once that process is complete, restart bcfg2-server)
