[boost] Boost.Log crash - question on consequences of misconfiguration

Subject: [boost] Boost.Log crash - question on consequences of misconfiguration

LS,

 

My question regarding Boost.Log is the following: could anything been said
on what to expect when asking Boost.Log to write to a non-existing directory
on a read-only drive? Does it keep trying to write or give up when the
directory cannot be created, and would the user be informed in such a case? 

 

Background: today I ran into a problem using Boost.Log. I configured both a
Console and a TextFile backend (both autoflushing) but happened to configure
the latter wrongly- setting the location of the file on a not-existing
directory on a read-only drive. This caused a program crash under certain
circumstances -  but no problems under other circumstances (related to the
configuration of the application which should not be relevant here) - when
it did crash, this happened after a few messages were logged. Crash happened
shortly before program termination but before the main() function was
terminated (for a while I thought I was seeing the problem described in the
docs regarding the boost.filesystem related problem and it took me a while
to learn this was not the case).
