wedged repository

[Polly Chase <ch...@aps.org>]

Hi,

The svnbook says:

[In the course of using your Subversion repository, fatal errors (such as 
running out of disk space or available memory) or interruptions can prevent a 
process from having the chance to remove the locks it has placed in the 
database. The result is that the back-end database system gets "wedged". When 
this happens, any attempts to access the repository hang indefinitely]

If the repository is being accessed from a web interface, is there any way
to ensure that it never becomes wedged as a result of interruptions, for
example? The users of the web interface would not be able to run
svnadmin recover.

Thank you.

I think you are confusing when the user presses the STOP button on their browser 
(which interrupts only the web client) with running out of RAM/disk/CTRL-C 
(interrupts the server).  Only something that can interrupt the server process 
has the /potential/ for wedging the repository.  Additionally, AFAIK that 
paragraph dates from pre-1.0 days when it was possible to wedge the server by 
interupting the commandline client (actually that is very pre-1.0).

In my opinion, I don't think you should spend a lot of time worrying about this 
issue if you use exclusively HTTP access...
