Project: Namespace-based translator selection
---
## Current Task
Write the filesystem proxy for namespace-based translator selection (*nsmux*).
The code is at <http://github.com/scolobb/nsmux/tree/master>.
---
###Did this week
* Modified the node cache so that it maintains shadow nodes alive.
###Plans for the next week
* Implement the shutting down of translator stacks when *nsmux* is asked to go away (in case **antrik** considers that necessary).
* Make *nsmux* provide the access to the translator stack of the real node, in case a translator (mainly, a filter) should ask for its underlying node to be opened in O_NOTRANS mode.
---
###Current Status
####DONE:
* The skeleton which mirrors the filesystem.
* Provide proxy nodes (modify the standard version of netfs_S_dir_lookup).
####TODO:
* Create the generic filtering translator.
* Create the translator '0' (providing the untranslated version of the
node).
* Create the "recursive wrappers" for one-node translators.
* Create special translators for the main proxy so that its functionality
should be complete.
* Implement sharing of dynamic translator stacks where possible.
* Make dynamic translators go away as soon as they are not required.
* Refine the skeleton in several places so that it should become faster
and more reliable.
* Kill bugs.
* Integrate nsmux upstream.
* Solve the libtrivfs stacking issue.
* Patch libnetfs (it does not support file_get_translator_cntl, for
instance).

###Progress
####8: Fri Sep 19:
> Modified the ncache so that it now maintains shadow nodes (and directory nodes too, it is a side effect at the moment) alive.
####7: Sat Aug 30 - Fri Sep 5:
> Added the code for shutting down dynamic translator stacks.
####6: Mon Aug 4 - Fri Aug 29:
> Implemented the proxy nodes.
####5: Thu Jul 24 - Thu Jul 24:
> Created a *libnetfs*-based one-node translator, working exactly like the *libtrivfs*-based translator I had written before; the former, however, can be included in a translator stack.
####4: Tue Jul 22 - Thu Jul 24:
> Attempted to make a *libtrivfs*-based translator to be able to be stacked upon itself (to be able to receive a translator on top of itself, more exactly); attempted to borrow some code from *libnetfs* but this didn't bring any results.
####3: Sun Jul 20 - Tue Jul 22:
> Implemented the possibility to propagate a translator on all files belonging to a directory 'dir' in the request of the type 'dir,,x/'.
####2: Thu Jul 17 - Fri Jul 18:
> Extended the lookup code in *nsmux* to allow for looking up nodes like 'file,,x' and added the possibility to escape the double-comma in the following way: ',,,'.
####1: Mon Jul 12 - Tue Jul 13:
> Implemented a simple *libtrivfs*-based translator to test the lookup code for *nsmux*.
####0: Sat Jul 12 - Sat Jul 12:
> Made small changes to the code of *filterfs* to fit the needs of *nsmux*.
---
## Completed Tasks
####2: Sat May 3 - Fri Jul 17:
> Write a translator that should filter the contents of the directory it is set on according to some property. The property can be an arbitrary command.
> The code is at <http://github.com/scolobb/filterfs/tree/master>.
####1: Mon Apr 28 - Wed Apr 30:
> Wrote a Python extension module in C for retreiving the uptime. The module is based on the code of *w*.
####0: Sun Apr 27:
> Followed the code of *dmesgd* (<http://www.bddebian.com/junk/dmesgd/>) kindly offered by **bddebian** and rewrote it from scratch as a tutorial.
