Re: [basex-talk] Passing sequence of strings to the java class

Hi Christian,

Right now we are using the next code

public static String exec(String key) {
return ...
}

public static String exec(Object... keys) {
return ...
}

The code that doesn't work:

public static String exec(*String*... keys)

Hi, Vladimir,

If you will do db names with the particular prefix, for example "db_", you
may use the next code

let $docs := for $i in db:list()[starts-with(.,"db_")] return db:open($i)
return $docs/*

Hey Vladimir,

You can use sharding approach for you data import and split all DBs even

Re: [basex-talk] Full-Text

[Alexander Shpack]

Hey, Vladimir!

Just put this specific files to the separated DB and than index it.

You can process it automatically, BaseX allows to create and index DB right
from XQuery.

I hope it helps you. Anyhow, you can provide more details about your task
and we can figure out the best solution for you.

[basex-talk] Fwd: Passing sequence of strings to the java class

[Alexander Shpack]

Hey, team!

Just simple question. How to pass sequence of string to the java class?

let $values := for $i in (1 to 3) return $i cast to xs:string
return j:exec($values)

In case when local function returns one item all is good. Otherwise  j:exec
takes array of item()+, but not the array of stings.

If you just call j:exec(("1","2")) than all works as expected.

Any thoughts? Is it bug or feature? ;)

I think TagSoup is good enough. But it requires some html5 tuning. I know

[basex-talk] TagSoup and html5 support

[Alexander Shpack]

Hi team!

As you know, TagSoup 1.2.1 doesn't support correct HTML5 tag nesting. For
example, this string
Test
will be parsed as


But html5 code
Test
will be parsed as is.

How to implement in BaseX the html5 support?
I've found this project, but not sure that it's possible to add it into basex
code

Thanks!

Re: [basex-talk] Nonstandard CSV in RESTXQ

[Alexander Shpack]

One more thing. I've written the next code in GUI, and it works perfect.

let $fName := "test.csv"
let $content := file:read-text($fName, "cp1251")
let $csv := csv:parse($content, map{ 'separator': ';', 'header': false() } )
return $csv

What the difference between post data and raw file?

I've tried it, it works. Almost fine. Now I have an issue with encoding.
Seems like 'encoding' parameter was not applied

No, browser doesn't want to send file content with this mime type. The
other thing, RFC describes "text/csv" mime type. Are you sure that
"text/comma-separated-values" is the correct one?

[basex-talk] Module parsing performance

[Alexander Shpack]

Hi BaseX team!

How to increase performance of parsing and executing on custom xqm module?
I have 10K lines of sxq code and it makes huge CPU load on the parsing
process.

Any ideas?

Re: [basex-talk] 8.2 on Windows. RESTXQ demo doesn't work.

[Alexander Shpack]

I replied inline

* Is it the .basex file which is located in C:\Program Files (x86)\BaseX ?


No, it's located in C:\Users\user\.basex


 * What happens if you start the start menu shortcut BaseX Server (Start)?


C:/Program Files (x86)/BaseX/.basex: writing new configuration file.
HTTP Server was started (port: 8984)

Now it works fine

[Alexander Shpack]

Guys, I installed BaseX from *.exe* installator, not from .zip file.

 Alexander,

 No issue I am getting.Christian made it perfect.

 I downloaded war file and unzip to somewhere. Then modify WEB-INF/web.xml
 file. I modified these lines

   context-param
 param-nameorg.basex.restxqpath/param-name
 param-value/home/eakarsu/apache-tomcat-8.0.22/basex/param-value
   /context-param
   context-param
 param-nameorg.basex.dbpath/param-name

 param-value/home/eakarsu/apache-tomcat-8.0.22/basex/data/param-value
   /context-param
   context-param
 param-nameorg.basex.repopath/param-name

 param-value/home/eakarsu/apache-tomcat-8.0.22/basex/repo/param-value
   /context-param

 Copy files in WEB-INF folder contents to above configured location for
 org.basex.restxqpath so that you will have this:

 [eakarsu@norshin ~/apache-tomcat-8.0.22/basex]$ ls
 datadbareporestxq.xqmstatic


 Then build war file (BaseX82c.war)  again and drop it to webapps folder of
 apache tomcat.

 Restart apache.

 You can access

 http://localhost:8080/BaseX82c/dba

 http://localhost:8080/BaseX82c/hello/World

 Hi BaseX team!

 It doesn't work, because WEBPATH contains (by default) a path to a local
 user's BaseXWeb folder, not to a webapp folder inside BaseX installation
 folder

 I was confused a bit, why clean installation of 8.2 doesn't work, when
 8.1 works fine

 Thanks

I installed BaseX from .exe file.

 I am confused. It works for me. This is what I did:

 * downloaded BaseX82.zip
 * unzipped to c:\users\user\Desktop
 * started c:\Users\user\Desktop\basex\bin\basexhttp.bat
 * visited http://localhost:8984/

 This is an extract from the newly created .basex file:

 # HTTP Services
 WEBPATH = C:/Users/user/Desktop/basex/webapp
 RESTPATH =
 RESTXQPATH =

 This is what is shown on command line when starting basexhttp.bat:

 C:/Users/user/Desktop/basex/.basex: writing new configuration file.

 Do you possibly have some more hints on what goes wrong in your
 environment?

Re: [basex-talk] BaseX: Upcoming Features

[Alexander Shpack]

Hi Christian,

What about redo logs and master/slave replication?

 Dear BaseX aficionados,

 An upcoming version of our software (7.9 or 8.0) will make it much
 easier to perform updates and return items at the same time [1]. It
 will also contain an xquery:update function and will bring xquery:eval
 and xquery:evaluate together again [2] Another exciting and
 sophisticated feature we are working on is query precompilation [3],
 which will particularly speed up large XQuery applications and allow
 for more request-specific optimizations.

 Next, we are working on a Database Administration interface based on
 RESTXQ, and we will also drop out the confusing client/server dialog
 from the GUI.

 Feature 1 and 2 are already available via a feature branch [4]. If you
 are working with the git sources, we are excited to get your feedback!

[basex-talk] Too many opened files error

[Alexander Shpack]

Hello!


for $i in (1 to 1000)
  let $name := 'user_' || $i
return
  (
  db:create( $name )
)

Is it bug, or normal behavior?

I would like to create little benchmark with multiple databases,
multiple writtings and readings to it.

[basex-talk] Proposals. Custom query slot management, named instances and read-only databases

[Alexander Shpack]

Hi everyone!

Our current project, based on BaseX, was failed on launch, because we
have any practice with optimization for NoSQL databases and take the
bottleneck with write locks, but we take the unbelievable experience
with BaseX.

Today I know, how to get the maximum from this DB

1. Custom query slot management.
It would be useful, if query command can take the number of taken slot.
From code side I know, that some type of requests is very simple, very
fast, and DB can return rapidly the results back. And this type of
requests may be sticked to some query slots permanently. From other
side, heavy xQuery code may be managed automatically by BaseX

2. Named instances
We need to start multiple BaseX servers to utilize more then one CPU
core. It would be useful to set up the name for each instance by
personal .basex config

3. Access mode
Next proposal is simple. Allow to manage the type of access (read or
write only, both) to DB for list of named instances.

This proposal may help with the next architecture: many servers with one DBPATH.

Server1Server2 Server3
|  ||

  |||   |
DB1  DB2  DB3   DB4

DB1 permissions
 Read: Server1, Server3
 Write: Server2

DB2, DB3, DB4 permissions
 Read: Server1, Server2
 Write: Server2

This may protect from DB corrupts.

Is it interesting concept?

[basex-talk] Improvements. On-fly in-memory temporary index

[Alexander Shpack]

Hi Folks!

I had one task with csv parsing and transforming. Main file contains
approximately 100k of nodes.
Transformation process should be in memory only, and I thought, that
in-memory temporary index would be useful for this type of tasks.

Useful scenario

copy $clone := $csvContent
modify
  (
tmp:optimize($clone),
...
  )
return $clone

Main goal - increase performance with huge document fragments,
modified and changed on-fly.

Is it possible?

[basex-talk] Proposition. Execution feedback

[Alexander Shpack]

Hi!

It would be perfect to take execution feedback from GUI or server.
Execution plan: N nodes
Processed: K nodes

It may help in script optimization and understanding complexity of xQuery task

[basex-talk] Proposition for the GUI features

[Alexander Shpack]

Hi everyone!

I have a nice idea, how to stop to crack the database, when user use
GUI and server simultaneously.
When GUI will found launched server, every updating functions should
be executed through port, not directly.

User may setup different connections (require list of connections),
select the default connection, and choose method of connection: direct
access or via saved one

Sorry for my bad English.
