James Peach commented on TS-315:
--------------------------------
I think we need a better name than
{{proxy.config.disable_configuration_modification}}. The closest existing
configuration I can find is {{proxy.config.config_update_interval_ms}}, so
consider grouping these in a subtree.
If this configuration can be modified, then it is possible to escalate from (1)
back to (0). Not sure whether this is desirable or not. I assume that with the
setting (2) no configurations could be modified? Except per-txn overrides?

> In production, in order to improve site stability, it is imperative that TS
> never accidentally overwrite its own
> configuration files.
> For this reason, we'd like to request a switch be added to TS, preferably via
> the command line, that disables all
> automatic configuration file generation or other runtime behavioral changes
> initiated by any form of IPC other than
> 'traffic_line -x' (including the web interface, etc.)

> A very crucial request, in my opinion. If TS needs to be able to read
> command-line config changes on the fly, these
> changes should be stored in another config file (for example
> remap.config.local instead of remap.config). We have a
> patch config package that overwrites 4 of the config files under
> /home/conf/ts/, and with all packages
> we'd like to think that the content of these files can't change outside our
> control.

> traffic_line -x doesn't modify the configuration, it reloads the
> configuration files. If we want to have an option for
> this it would be good to have it as an option configuration file (CONFIG
> proxy.config.write_protect INT 1).
> It would be an equivalent of write protecting floppies (ahh the memories)...

> I don't think it would be a good idea to have this in the configuration file,
> as it would introduce a chicken/egg
> problem.

> So I'm not 100% positive that this isn't just a bad interaction. Now, it's
> only
> triggered when trafficserver is running, but usually what ends up happening
> is that we get a records.config which
> looks like it's the default config that comes with the trafficserver package.
> It's possible it's all one and the same issue, or we might have two issues.
