[naviserver-devel] status update

[Gustaf N. <ne...@wu...>]

Dear naviservlers,

a short update on the changes in the tip version of Naviserver
and some modules on bitbucket:

- i've not made the big-cleanup of unused functions, but
   marked several as deprecated. The server reports
   now in the error.log when deprecated (C- or
   Tcl-implemented) functions are used.

- the introspection interface for per-server and per-pool
   reporting is implemented and works nicely (used e.g. in
   the updated nsstats.tcl or in my set of munin plugins).
   The old interface (which was not virtual-server and
   pool-aware) is marked as deprecated.

- i've moved several locks from global mutexes on all
   pools to muxtes per pool where appropriate to further
   improve scalability (most people won't notice)

- nsdbpg: i've updated the interface of nsdbpg from
   the old string based interface to Tcl_Objs and implemented
   for the provided SQL statements a new Tcl_Obj type named
   " parsedSQL", which can reduce string copying and the
   parsing of SQL statements for the bind-var emulation
   significantly. When the Tcl_Obj is preserved, the
   SQL statement is processed once (at the first call)
   and the resulting C structures are preserved in the
   internal representation of the Tcl_Obj. In later calls,
   the internal representation of the parsed SQL statement
   can be reused without overhead.

- I am updating the documentation whenever i step over
   some documentation problems, so it is improving, but
   there is still a log way to go.

When downloading the tip version of naviserver, please
get also nsdbpg/nsssl/nsstats when you use these modules.

We are using the tip version of naviserver and the modules
in production since a while. I think, we saw the last crash
last year in october or so.

best regards
