Hi George, > how can a basexclient execute XQUERY > "import module namespace test = "test" at "test.xq" if there isn't a > querypath to define the directory for the modules? One way is to specify the base URI in your query [1]. If you frequently import server-side modules, the approach we recommend is to move the modules into the repository. Hope this helps, Christian [1] https://www.w3.org/TR/xquery-31/#id-base-uri-decl [2] http://docs.basex.org/wiki/Repository
Re: [basex-talk] standalone vs GUI character parsing
I pass this on to the Docker aficionados on the list… Christian Thanks and sorry for responding on a month old post about the xml parser, I just noticed my email filters were not working. About the QUERYPATH, I think the issue isn't specifically about docker. Maybe I'm missing something, but how can a basexclient execute XQUERY "import module namespace test = "test" at "test.xq" if there isn't a querypath to define the directory for the modules? I'm trying this on a local server instance and it searches for the test.xq in the BaseX bin directory. I hope there is an alternative way to declare the path, because I won't be able to use BaseX any more from my java application, using the BasexClient query method. Specifically about Docker, the older images can't run because of the .m2 permissions, and the latest one is missing QUERYPATH.

Re: [basex-talk] standalone vs GUI character parsing
What about characters that outside the UTF-8 scope? I think that still makes the internal parser to fail. I thought that was intended behaviour so I never mentioned it. On 09/30/2016 03:10 PM, Christian Grün wrote: By default, XML documents with invalid characters should be rejected; but if you turn on the internal parser in the parsing tab of the Database Creation dialog, all invalid characters will be replaced with FFFD. Maybe that’s what you have done? I also noticed that the QUERYPATH has been removed from latest builds, how can I set the Docker image to find xq modules? I was using the QUERYPATH to map them.

Re: [basex-talk] Check if server is running, silently
I was looking in the wrong places. The error I was trying to hide was a
socket() error, but that is actually a PHP error and not a BaseX Exception!
Errors and exceptions are handled differently of course. So I had to resort to
PHP error_reporting to temporarily disable the generated error when we can't
connect to the server. Like this:
// error_reporting returns last state it was in
$previousReportingLevel = error_reporting(0);
$session = new Session($dbhost, $dbport, $dbuser, $dbpwd);
error_reporting($previousReportingLevel);
You still have to wrap this in a try/catch block and ignore the catch though,
because the BaseX script will also throw a 'Can't communicate with server'
error. I'm not sure why this is the case. Considering PHP already returns false
AND reports an error on socket_connect() fail it might be better to just return
false when this error occurs on session creation. That way we can still throw
our own Exception if needed, but more importantly we get a false return when
the server cannot be connected to. Just a thought.
Kind regards
Bram

Hi Bram,
Unfortunately I cannot give you help on PHP (my knowledge about this language
is around 20 years old now). If you check out our Java sources [1], you will
see that our ping does basically the same what you do: We try to create a
connection and return true if we succeed.
Regarding logging, I would assume that it’s your freedom to decide what you do
in the catch branch. I am not sure where/when Apache comes into play in your
setup?

[basex-talk] Check if server is running, silently
Hi all
To make clear to users which corpora are currently available and which
aren't, I'm checking to see if a BaseX server instance exists and then check
if a specific database exists. Testing for the database is done with
db:query (as I learned through this mailinglist), but I'm not sure how I can
silently test for the server in PHP.
All BaseX examples use try-catch blocks, which makes sense to catch errors
that go wrong, and do something with them. If I'm not mistaken these errors
are automatically logged by Apache (maybe also by other webservices). This
means that if I'm only checking the existence of a server with the code
below (variables left out), I will always write an error to a log file.
Obviously, that is not what I want because I know that the error 'Cannot
communicate with server' is to be expected when the server does not exist!
try {
$session = new Session($dbhost, $dbport, $dbuser, $dbpwd);
// db:exists returns a string 'false', still need to convert to
bool
$corpusExists =
toBoolean($session->query("db:exists('$databaseName')")->execute());
$session->close();
if ($corpusExists) {
$availabilityArray[] = $databaseName;
}
} catch (Exception $e) {
//
}
This script works perfectly fine, but I do not want the errors to be logged
(for this case) to prevent my error log to be full of the same error. Is
there another way to test for a BaseX instance only? For instance, a way to
return false when the server does not exist, I could do something like:
$session = new Session($dbhost, $dbport, $dbuser, $dbpwd);
If ($session) {
// db:exists returns a string 'false', still need to convert to
bool
$corpusExists =
toBoolean($session->query("db:exists('$databaseName')")->execute());
$session->close();
if ($corpusExists) {
$availabilityArray[] = $databaseName;
}
}
Thank you in advance
Bram Vanroy
