Re: [Qgis-developer] Warning - shapefile corruption on 2.16/master and how to recover

[Randal Hale]

I just ran a test

Ubuntu Linux
QGIS 2.16.2
Shapefile with 925,000+ polygons

I opened the attribute table which took a bit.
Started editing.
Split 5 polygons.
Saved.
Stopped editing.
Removed the layer.
Added it back - it didn't corrupt.

I'm wondering if I should have done something more deliberate like 
delete or add more polygons.

- start editing

- after a while waiting for nodes to appear as QGIS works, message is 
displayed of "qgis-bin.exe has stopped working"


With QGIS 2.14.0:

- exact same issue when starting editing of that layer

With QGIS 1.8.0:

- able to click start editing and no crash as nodes are displayed for 
world


- able to use "Split Features" and save edits

- seems to write changes to .dbf .shp .shx (to be honest, changes 
don't look like a valid feature split, hard to tell, but it seems a 
few more feature records were added)


You likely aren't happy that I tried with such large of a file, but, 
it was honestly the first big file that I found.



other test for fun:

- checked layer summary through ogrinfo
- indexed the .shp with the shptree utility (generates 22MB .qix index 
file, wow)
- created a small MapServer mapfile with only that layer, for world 
extents
- generated map image through MapServer, recording layer draw speed 
(cool!)
- tried to compare that speed, to QGIS 2.16.2 loading that same 
shapefile (doing both a same time)


Fun results!  Any guess how MapServer did?  :)

Honestly I didn't plan to check that, and that is not why I tried to 
help here, but when I saw QGIS having a hard time with this large 
file, on a 16MB RAM new machine, I thought 'hmm i wonder how MapServer 
would handle this huge file?'   For one of the previous WMS

shapefile, and we had to fix the indexing for MapServer...so it is 
good to try to push limits once in a while.


sorry if i offend anyone with these tests, was just having some fun

Let me know if you need more tests.

it would be fun, yet make no sense to technical people, to compare 
MapServer WFS output or WFS-Transaction requests, versus other tools 
like QGIS editing.  But that is apples vs oranges and could never be 
agreed upon by development teams (or any sane person).


Anyway, I was just having some fun pushing MapServer.

I hope those tests are somewhat useful!

I just tried to reproduce with QGIS 2.16.2 on Windows 10, I had no 
problems using the "Split Features" tool on a shapefile, and saving. I 
notice that the .dbf .shp .shx were modified properly.

Re: [Qgis-developer] Warning - shapefile corruption on 2.16/master and how to recover

[Lene Fischer]

Hi Nyall,
I have been using 2.16 in a 3 week summer class. We have been using these 
functions, and not seen the described errors.
We use OS : Windows 7 and 8 - the MAC users was using 2.14

Is it on Linux you get the errors ?

Emne: [Qgis-developer] Warning - shapefile corruption on 2.16/master and how to 
recover

Unfortunately a fairly nasty regression has slipped in to 2.16 and is still 
present on master. This results in shapefile corruption in certain 
circumstances.

While I've hit this issue maybe 3 or 4 times in the last 2 months, I haven't 
been able to track down exactly what causes this. It seems related to using the 
split or reshape tool on a shapefile, then saving the changes and getting the 
errors "Cannot reopen datasource
xxx.shp|layerid=0 in read-only mode" and "Data source is invalid (Unable to 
open xxx.shx or xxx.SHX.Try --config SHAPE_RESTORE_SHX true to restore or 
create it)" in the log.

A full report is at http://hub.qgis.org/issues/15570

Hopefully we can resolve this before the next round of releases. In the 
meantime, there's a workaround for recovering data:

In the same folder as the shapefile there'll be additional files 
"xxx_packed.shp" and "xxx_packed.shx". Renaming the "xxx_packed.shx"
file to "xxx.shx" allows the original shapefile to be reopened.

Ah.. Purely a QGIS thing, but not completely internal in the meaning that it 
can be used by code building a connection string (eg in unit tests) and it is 
actually documented in http://qgis.org/api/classQgsVectorLayer.html#details

So if we wanted to change that we should probably accept the old value as 
well.

[Qgis-developer] Error in WFS QgsDataProvider.dataSourceUri()?

[Tom Chadwin]

It includes "retrictToRequestBBOX" (missing an 's'). Should be
"restrictToRequestBBOX". Don't know if this is internal to QGIS, or if it's
eg OGR. Also don't know what breakages would be caused by fixing it.

Thanks

Tom

Re: [Qgis-developer] Warning - shapefile corruption on 2.16/master and how to recover

Hi Nyall,


2016-09-16 3:08 GMT+02:00 Nyall Dawson :

Unfortunately a fairly nasty regression has slipped in to 2.16 and is

perhaps, the name "NODEB" stands for  "--NODEBug"   ?   :(

well,  but today  a SHP is not so important   ;)

Serioulsly,  do you have some  plugin active ?   Do you tested with
"--NOPLUGINS"  option active ?
Do you can try renaming  .qgis2   directory,  so that we are sure  QGIS  do
no use it ?
And what is the result ?

Please, let us know.


Regards

Roberto

There was another report of Shapefile corruption earlier with 2.14 which I 
thought it could be side effects of the solution for #11007:

geez... this unfortunately sounds familiar... remember all the issues with 
deleted features and shapefiles opened in software other than QGIS?

Can this be something related to that?

Re: [Qgis-developer] Qgis donload entire postgis data table (with geom?) opening attribute table

[Pietro Rossin]

@Nyall
Thanks, it would be nice if it will be fixed in next releases..
Other nice thing would be the possibility to select if we want to fetch the
geometry column, and which geometry column opening attribute table..

A user could add more than a single geometry column in a postgis table, for
example full resolution- half, a quarter etc.. with a trigger to update the
lower resolution ones after a geometry update.
This could be usefull in web publishing applications..
Now we are using Lizmap and I create some materialized views to create
visualization by scale in my project. Having more than one geometry column
(not fetched loading attribute table) could lower the mess and maintenance
(refresh materialized views etc)..

@DelazJ
Thanks, I didn't see it
Anyway selecting "Plain text, no geometry" don't fix the fetching of the
geometry column opening attribute table and copy/paste it..

Cheers
Pietro

Hi,
Pietro, the WKT option is still available in Settings --> Options --> Data
Sources, and in the listbox "copy features as", select "Plain text, no
geometry".

Well - it's actually a bug. The geometry shouldn't be getting fetched
here unless it's required. I looked into this a couple of weeks back
and there's a few issues in the caching mechanism which means it's not
being utilised correctly. I haven't had a chance yet to address these.

No - it's on Windows. And I can't reproduce it everytime, but it has
