Description

CFengine is unable to handle too big files payloads in the Enforce a file content Technique.

In Rudder 3.0, the limit is at 16ko and the error is at the promise validation time
The error message is:

input buffer overflow, can't enlarge buffer because scanner uses REJECT

Before, the limit is at 4ko ou 8ko, and for example, when trying to apply a backup-manager configuration using it, there is a deployment error, outputting this:

Expansion overflow constructing string. Increase CF_EXPANDSIZE macro. Tried to add "

# If you want to encrypt your archives locally, Backup Manager

# Targets to backup

# You can use two different variables for defining the targets of 
# your backups, either a simple space-separated list (BM_TARBALL_DIRECTORIES)
# or an array (BM_TARBALL_TARGETS[]).
# Use the first one for simple path that doesn't contain spaces in their name.
# Use the former if you want to specify paths to backups with spaces.

# It's recommanded to use BM_TARBALL_TARGETS[] though.
# Warning! You *must not* use both variables at the same time.
# NOTE: The Debian package will only update BM_TARBALL_DIRECTORIES 

# Paths without spaces in their name:
export BM_TARBALL_DIRECTORIES="/etc /home/* /root /var/log" 

# If one or more of the targets contain a space, use the array:
# declare -a BM_TARBALL_TARGETS
# BM_TARBALL_TARGETS[0]="/etc" 
# BM_TARBALL_TARGETS[1]="/boot" 
# export BM_TARBALL_TARGETS

# Files to exclude when generating tarballs, you can put absolute 
# or relative paths, Bash wildcards are possible.
export BM_TARBALL_BLACKLIST="/var/archives" 

# With the "dar" filetype, you can choose a maximum slice limit.
export BM_TARBALL_SLICESIZE="1000M" 

# Extra options to append to the tarball generation 
# (take care to what you do; this will be silently added to the 
# command line.)
export BM_TARBALL_EXTRA_OPTIONS=""

Fatal cfengine error: Can't expand varstring
[2012-07-31 12:15:21] ERROR com.normation.rudder.services.policies.RudderCf3PromisesFileWriterServiceImpl - The generated promises at /var/rudder/share/713c52d2-78d8-4dbe-87be-21457496de32.new/rules/cfengine-community are invalid

I do think this is because CFengine is unable to handle such big variables unless compiled with a larger CF_EXPANDSIZE. But in that case, it is better to use a file template, I think.

This has been fixed in later version of CFEngine; i can't really find out when, but with a CFEngine 3.4.1, it doesn't happen
I suspect that https://github.com/cfengine/core/pull/200/ is part of the solution

So by using 3.4.2, this should be automatically fixed

Now that we use CFEngine 3.4.4 on Rudder 2.6, shouldn't we consider this bug as resolved (unless this is a 2.3, 2.4 or 2.5 bug) ?

Just so that we keep track on this; CFEngine is tackling the issue of removing the 4K barrier, one step at a time.
This should work correctly on Rudder 3.0 (see ticket https://dev.cfengine.com/issues/2912)

Could someone test it in Rudder 3.0 so that we know if it works (or update the bug on CFEngine side ?) Nicolas ?
