[Qgis-user] GDAL locks and filetype support

[Paul Wittle]

Hi,

Following on from my previous email it is clear that quite a bit of work would be required to substantially change the way that QGIS / GDAL is opening MapInfo tab files (and probably other formats as well). We are interested in crowd funding the fix so please get in touch if you are interested and I'll see if I can setup something.

However, in the short term I wondered if there is a setting I can use to block MapInfo tab files altogether. We want to ban our users from using them in QGIS altogether and push them to use database source layers instead as this seems to be the safest format.

Does anyone know if there is a list I can modify to remove MapInfo tab file till we have a fix?

I had been recommending GeoPackages but to be honest they are more of a nightmare than TAB files on our networked Windows environment. We  have found that two users accessing the same GeoPackage can occasionally lock each other out but that is even worse in that there is no way to stop QGIS. I have had to physically turn off the offending PC to get it to drop the file and restore access to other users. It locks out on the operating system so that makes me even more worried about recommending its use.

I'm a massive advocate of QGIS and working hard to roll it out but it's been a bad couple of weeks with file locks disrupting our users. I'm hoping the database file format (Oracle) will be safe!

If anyone else is having similar issues I'd love to hear from you.
Thanks,
