2 or 3, don't include the release number).

/* NJS 2006-04-28
In earlier versions of this script, which eprints to count was
determined by comparing the request date of the eprint against the
"lastproc" date of this script (i.e., minimum time unit one day).
This was fine if you only ran the script once per day, but if you ran
it more than that, it counted multiple times requests whose
$request_date == $lastproc. For example, if you ran this script five
times per day, all the downloads that occurred during that day would
be counted EVERY TIME this script ran, thus overinflating your stats
by a factor of up to five :(
The solution is to use the full time stamp for comparison rather than
just the date. This timestamp MUST include time zone information so
that things don't get screwed up by daylight saving time. As long as
this is done consistently, there's no need to do things like convert
to GMT, for example.
The very first thing we need to do is grab the current time stamp
with time zone, which will later be stored in the database as the
"lastproc" time. This needs to happen first so that we don't "lose"
any requests that occur while the script is running.
*/
$start_time = date('Y-m-d H:i:s O');
/* NJS 2007-01-30
A further twist! The original script ignored log lines that had a
date falling before $lastproc, i.e., if log line date < $lastproc
then it's already been dealt with. This is all fine. However, it
didn't bother checking for log lines that were written after the
script started running (i.e. log line date >= $start_time).
Why is this a problem? We're reading the live Apache log file, so
it's quite likely that new lines will be written to it after the
script has started (i.e., after $start_time). Suppose $start_time is
'2006-06-15 14:03:15 +1200', $lastproc is '2006-06-15 12:03:15 +1200'
(i.e., the script is run every two hours) and the log file contains
lines with the following dates:
'2006-06-15 10:03:15 +1200' [1] <-- written before $lastproc
'2006-06-15 12:03:14 +1200' [2] <-- written before $lastproc
'2006-06-15 13:03:15 +1200' [3] <-- written before $start_time
'2006-06-15 14:03:14 +1200' [4] <-- written before $start_time
'2006-06-15 14:03:15 +1200' [5] <-- written at $start_time
'2006-06-15 14:03:16 +1200' [6] <-- written after $start_time
During this run, dates [1] and [2] are both < $lastproc and thus
ignored. The remaining four dates ([4]--[6]) are >= $lastproc and
thus processed.
Two hours later, the script runs again, this time with $start_time
set to '2006-06-15 16:03:15 +1200' and $lastproc to '2006-06-15
14:03:15 +1200'. Dates [1] through [4] are all < $lastproc and
thus ignored. However, dates [5] and [6] are both >= $lastproc
and are processed a second time, resulting in a duplicate entry
in the database.
The solution is to ignore any log line entries that occur at or after
(>=) $start_time. In the example above, this would mean that in the
first run, dates [1], [2], [5] and [6] would be ignored and dates [3]
and [4] processed. In the second run, dates [1]--[4] would be ignored
and dates [5] and [6] processed.

IP address ranges for your local Intranet(s). You can have multiple
ranges of IP addresses, each with a different "country name", so that
they will appear as separate entries in the by country stats pages.
You should use a different country code for each range (ISO 3166-1
specifies the range XA through XZ as "user-assignable", so you can use
codes from there as necessary), and create flag icons as appropriate.
Each address range key is the name that will appear in the statistics
database (the "country name"), followed by a comma, followed by the
appropriate ISO 3166-1 country code as noted above. Each entry in the
range is either a single IP address, or an array specifying a lower and
upper bound for a contiguous IP address range (see example below).
All IP addresses must be converted to long values using the ip2long()
function before being stored.
Note that address ranges may overlap. The script will use the first
range that matches a given IP, so list the ranges in the correct order
of precedence for your needs.
Example:
$local_IPs = array(
'Repository Admin,XA' => array(
ip2long('192.168.1.5'),
ip2long('192.168.1.22'),
array(
lower => ip2long('192.168.1.30'),
upper => ip2long('192.168.1.35'),
),
),
'Our Intranet,XI' => array(
array(
lower => ip2long('192.168.1.0'),
upper => ip2long('192.168.255.255'),
),
),
);
'Repository Admin' covers the IP addresses 192.168.1.5, 192.168.1.22 and
the range 192.168.1.30 to 192.168.1.35, inclusive. 'Our Intranet' covers
the range 192.168.1.0 to 192.168.255.255, inclusive. A machine will only
match the 'Our Intranet' range if it first fails to match the
'Repository Admin' range.

Patterns to match various search engine bots. Ideally, we'd use a similar
mechanism to the $local_IPs variable above, but this isn't feasible because
we'd need to know the IP ranges for the likes of Google, for example. This
clearly isn't possible in practice.
Fortunately, most search bots insert a readily identifiable string into
the user-agent part of the HTTP response, which gets recorded in the Apache
log file. We can look for these and re-code log entries as appropriate.
The format of this list is similar to that of the $local_IPs variable.
The key is the "country name" (in this case the name of the search
engine) plus a non-standard four-character country code starting with
"X@", separated by a comma. Each key value has an associated list of
corresponding regular expressions that can occur in the user-agent part
of the Apache log entry. If any one of these REs matches the user-agent
part of the log entry, then we should re-code the country appropriately.
A four-character code is used because that what the database allows, and
it avoids having to reserve several of the "X" country codes for search
engines.

NJS 2007-01-31
Refactored regexps from four down to one, after realising
that (a) long EPrints URLs are a superset of the short ones,
and (b) a regexp that matches domain names works just as well
for IP addresses (the GeoIP lookup doesn't care which it
gets). Also fixed the pattern so it can handle an arbitrary
number of subdomains. Note that the latter would be the main
argument for keeping a separate IP address pattern, as IP
addresses always comprise exactly four parts. However, it's
not really up to the script to verify IP addresses; Apache
should be recording them correctly in the first place!
