Xapian discuss - Mar 2012 - how to enable debugging

Ciao,

sorry for the silly question, but how do you enable debugging in
xapian? I'm using xapian-tpcsrc and would like it to print debugging
info (connections, queries, etc).

I'm configuring xapian 1.2.8 on OSX with "./configure
--enable-debug-verbose", then

$ export XAPIAN_DEBUG_FLAGS=-1
$ export XAPIAN_DEBUG_LOG=test.log
$ sudo xapian-tcpsrv /path/to/db --port 972
Starting server on port 972
Listening...
Connection from 127.0.0.1, port 48102
Connection from 127.0.0.1, port 48358
Got exception NetworkError: Received EOF (context: /path/to/db)
Closing connection.
Connection from 127.0.0.1, port 48614
Got exception NetworkError: Received EOF (context: /path/to/db)
Closing connection.

The client can connect and make queries but I can't find the expected
test.log.

I read NEWS and HACKING but they seem to have conflicting information

Thanks,
Matteo

PS: what are those NetworkError exceptions?

That option is no longer supported.  See
http://xapian.org/docs/deprecation - it's --enable-log you want now.
You should get a warning about passing an unknown option to configure
(though it's the first line output, so gets scrolled off the screen
quite soon):

$ ./configure --enable-debug-verbose
configure: WARNING: unrecognized options: --enable-debug-verbose
[...]

I don't see conflicting information.  The most recent NEWS entry about this
option documents its removal (in 1.1.0):

* configure: --enable-debug and --enable-debug-verbose have been deprecated
  since 1.0.0, so remove specific errors pointing to the replacements.

Older NEWS entries may not be correct for newer releases, but that's
because the NEWS file documents incremental changes in each release.

Just an indication that the server got EOF on the socket (which happens
when the client closes the connection).
