Mea culpa! I may have steered the train of conversation in a non-productive direction: my home is parsed due to how I launch the GUI. In any event, I haven't had any issues with parsing project files or symbolic links, either.

Apologies,
Bridger

For what it’s worth: in our developments we had a directory as part of the project files where we stored all queries that were executed during development and testing (these queries were dynamically created by other queries). Saving these queries is just part of our process. However, after a while that resulted in hundreds to thousands of query files. That resulted in a massive memory demand, and we noticed increased CPU usage, both of which we could not explain at first. Eventually we found out that the BaseX GUI automatically parsed all these queries, each time initializing a custom module we wrote, where the initialization of that module created a temporary directory with a number of files. The solution for us was to simply move the directory where we save the executed queries somewhere outside of the project files opened in the BaseX GUI.

 

Best regards,

Never had a problem with the GUI parsing project files.  No issues with symbolic links.

 

I have generally found basex very reliable but never try to update the installed version; it's always move the old, unpack the new.

Thanks for your assessments. So maybe we should ensure that every file and directory will only be parsed once.

 

Did anyone of you have problems with the automatic parsing of project files in the BaseX GUI, or with symbolic links in particular?

Same for us over here. The ability to follow symlinks is a very powerful feature that we use to externalize folders (data, restxq for instance). So please don't remove it altogether!

I've been handling updates by making data/ a symbolic link to a data directory that's a sibling of the basex directory.  (Move the old, unpack the new, go into new and replace data/ with a symbolic link up and over.)

 

Would hate to see that stop working.

Good to hear that! I can’t recollect that something particular has changed in version 9.1.2, regarding the scanning of project files, but I’ll have some thoughts how we can trace and interrupt such loops (or ignore symbolic links instead).

Glad that helped :)

 

I see this when I start from a fresh install vs expanding the ZIP into the same directory.

Thanks Bridger!

 

Indeed, I quit basexgui and manually edited .basexgui to set the project directory to a newly created empty directory.  basexgui seems normal/stable after that.

 

I rarely, as in almost never, use wine but I didn't have this issue with previous versions of BaseX.  Something seems unexpected here.

Hi Rick, et al,

I think (but am not 100% sure) that the GUI defaults to looking through your home directory on startup. So, somewhere in `~/rick/.wine/dosdevices/...` you have symbolic links that are looped.

 

I think you might be able to circumvent this problem by finding `.basexgui` - it would probably be close to wherever you started the GUI from on your filesystem. I think you can edit some of the PATHS there and that may help?

 

Again, I'm not sure. HTH!

Best,

Bridger

The command-line seemed to be operating normally.

 

What exactly is/are my project directories?

 

I attached to the running GUI instance `strace -f -e trace=stat -p 13368` and it has infinite repetitions of:

 

[pid 13436] stat("/home/rick/.wine/dosdevices/z:/sys/class/thermal/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone2/subsystem/thermal_zone0/device/subsystem/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:75/subsystem/devices/PNP0C0A:02", 0x7f7beb2796e0) = -1 ELOOP (Too many levels of symbolic links)

 

What's going on here?

Looks like a endless loop that is caused by parsing the files in your project directory. Do you possibly have any symbolic links?

 

Can you reproduce the problem with a completely fresh BaseX zip archive?
