Qgis vector too long ошибка - ErrorsMaster.ru - большая энциклопедия ошибок и их решений

What is the bug or the crash?

I have a project with a large number of relatively complex layers, mostly PostgreSQL, but also some files and others, along with some tiled base maps. The project worked fine in 3.22.4, but has an uncaught exception in 3.24, 3.24.1, and 3.22.5 which pops up a dialog of «vector too long». This happens just after the project loads, and after dismissing the exception dialog a couple of times (maybe related to the number of layers with issues?), I can pan and zoom and some other things just fine — I haven’t tried anything fancy. However, if I try to exit, even if I discard changes to the project, it pops up again and stops qgis-bin.exe from exiting. The only solution is to kill the task. This doesn’t happen with other projects, even a simplified version of the project with issues. However, I’ve not been able to figure out which layers cause the problem. When I saw the bug in 3.24 I was hoping to find the time to bisect through removing layers, but I haven’t yet, but I wanted to report this now that I see it has not been fixed in 3.24.1 and has turned up in 3.22.5. Maybe that particular exception is obvious to someone, especially happening in the exit code path.

Steps to reproduce the issue

I don’t have a good reproducible test case. I’ll try to install debugging symbols and see if I can catch the exception in a debugger.

I have two vector layers:

the red one is ‘Landuse’
the orange is a vector extent of land below ‘1mAHD’ extracted from a 5 meter DEM.

I want to clip out the ‘Landuse’ under the ‘1mAHD’ layer. They both have fairly complex geometry as you can see. The «Clip» is taking forever so I’m wondering if there’s a Plugin, script or series of steps I could follow to complete this task faster and easier and without getting into doing things manually. i.e. editing all the small holes out!

The solution was a mix of many comments made on the question. The process used to perform the clip successfully was as follows.
The following processes were performed on the layer as 1 polygon.

Image A
image_a

First, I used the «Delete Holes» feature with a threshold setting of 10,000,000. This effectively removed any internal holes in the polygons
Second, I used the «Smooth» tool to reduce the number of boundary vertices in the polygon.
Third, I used the «Multipart to singleparts» tool (as Q would not let me edit the whole layer as 1 polygon)
Fourth, I had to manually edit all the small artifacts from the outsides of the clipping polygons to clean it up (Took a while !….). The resulting Polygon is shown in the second image.

Image B
image_b

Once these tasks were performed the «Clip» tool worked.The final output was the clipped landuse under 1mAHD. I was then able to calculate areas of each of the landuses under 1mAHD. Obviously there was a loss in accuracy due to the holes and external polygons being removed, but this was acceptable at the scale I was working with.

Image C
image_c

It seems that when the clipping overlay and underlying layers are highly detailed that the clipping tool does not work. Although it might on a smaller dataset. It would’ve been good to retain the detail and still perform the clip but the result was satisfactory nonetheless, with the steps detailed above.

When trying to sign an app directly from Safari or the Files app this error is received:

The app I’m trying to sign is unc0ver, v4.3.1

Device: iPhone Xs Max iOS 13.3

Edit, I fixed this by switching to another Apple ID, after which I received an “unknown error.” I turned off windows active virus scan and it finally signed.

Attempted gerbil-snot’s method of fixing this error to no avail. iPhone 6S, iOS 13.3.

Edit: Here’s what I did to get it to work.

Uninstall both Altserver and AltStore. Install newest versions if not updated.
Reinstall both. Sign into Altserver using new credentials. When AltStore is loaded, use the new credentials to sign in there too.
Keep Windows Security open, disable Real Time Protection
Sideload thru Files app or AltStore’s apps page.

In my experience I found that Windows Real Time Protection turned itself back on at some point. Check it frequently if you have the same issue.

The main issue I got was from Windows Real-Time Protection. It seems that when AltStore sends the IPA to AltServer windows detected it being an exploit. I guess Windows Defender is doing its job for once…

Specifically, I got these:

Explot:iPhoneOS/Vortex.B!MTB
Exploit:iPhoneOS/Dakkatoni.A
Trojan:Script/Wacatac.C!ml

Turning off WRTP and rerunning it made it work right away.

Instructions for turning WRTP off:

Open Windows Security/Defender
Click Virus & threat protection
Under Virus & threat protection settings, click the blue text «Manage Settings»
The first slider should be «Real-time protection». Turn it off.

Edit:
DO NOT FORGET TO TURN IT BACK ON AFTER BEING SIGNED!!!
WRTP IS EXTREMELY IMPORTANT (even though it has flaws) IT WILL STILL HELP YOU STAY SAFE.

I was getting «vector too long» error when trying to sign unc0ver. Solved it by just turning off windows real time protection, nothing else.

This is not a smart fix, you need to find the issue, usually ‘Exploit:iPhoneOS/Vortex.A!MTB’ and allow it, DO NOT turn off windows real time protection, it’s much needed.

@zayn008 You only need to turn it off TEMPORARILY whilst, you sign it. And even when I whitelisted the ‘Exploit:iPhoneOS/Vortex.A!MTB’, it would still continually block it, being a new file.

Also, @bjmvercelli make sure you turn it back on!!! I should have mentioned that.

This is not an issue AltStore can fix since it is an issue caused by Windows. The error message has been updated to better reflect the error. Closing this issue.

Я пытаюсь заполнить двумерный вектор (817 на 577) объектами, называемыми ячейками. Эти ячейки имеют набор значений элементов (поплавки, другие векторы и т.д.). В какой-то момент программа останавливается и выдает ошибку "vector<T> too long". Вот определение класса ячеек и полный цикл:

                }
            }
        cells=output;
        }

Несколько раз я обнаружил, что sizeof (cell) раз число ячеек в векторе предполагается меньше, чем vector :: max_size()

sizeof (ячейка) составляет 144 → 144 * 817 * 577 = 67882896

max_size — 268345455

Разве не должно быть достаточно места для всех ячеек, или я чего-то не хватает? Заранее спасибо!

I am working on ownership data at a US county level. I have one shapefile per county that contains thousands of tax parcels. I need to dissolve the polygons representing parcels owned by the same individual.

When the shapefile is not clean, the «Dissolve» tool in QGIS doesn’t seem to work, it freezes. I have to fix the geometry validity issues first using the «Check Geometry Validity» tool. However, I have sometimes hundreds of errors. It takes a lot of time to fix them manually. Is there any other strategies that could save me some time?

I am using QGIS 2.4.0.

Try running a subtle buffer on the polygons. A setting of -0.001 if your CRS is UTM would seem worth a try. VECTOR|BUFFER

When I have a layer with errors , I normally run it through the GRASS function v.clean in the Processing Toolbox. Though I never really figured out which tool is best in which case, I normally choose the bpol function there.

Maybe even more important it is to set the advanced parameters for snap tolerance and min area.
Depending on the layer, I usually choose 0.1 to 2 meters for snapping and e.g. 10 sqm for the minimum area.

The snapping e.g. aligns boundaries which are meant to be shared borders but have tiny offsets, the minimum area eliminates tiny slivers from intersections etc.

Together with the bpol, this normally resolves all errors without too much changing the topology.

You can use ST_MakeValid directly in QGIS adding lwgeom plugin that add lwgeom provider to processing toolbox => you can apply MakeValid directly on your loaded layer without converting in postigs/spatialite.
Postgis/spatialite use the same liblwgeom to do ST_MakeValid

you have to install liblwgeom and configure processing provider to point to it

lwgeom provider can be found as experimental:

I just ran in to a similar problem in qgis. I had a poly began projecting incorrectly. I used the Grass fuction v.clean in the Processing toolbox as Bernd suggested. Although bpol did not work, it seems to be fixed with the break function.

There is a standalone utility to fix this kind of problems, and I find it to be very reliable. It is called Shapechk by Andrew Williamson.

Типовые ошибки в QGIS, или когда что-то не работает

Не используйте кириллицу. Нигде — ни в именах файлов, ни в папках. Если в имени пользователя Windows/MacOS есть кириллица, то работайте, например, в какой-нибудь папке на диске C, D и тп. При использовании различных функций в QGIS файлы или папки на кириллице создают проблемы в дальнейшем. Если у вас имя пользователя на кириллице:

Вариант 1 http://gis-lab.info/forum/viewtopic.php?t=12380 и расширенная статья

Не стоит использовать пробелы в имени файла
Для векторных данных необходимо не забывать отключать редактирование!
После того, как мы выбрали какие-либо объекты и выполнили нужные нам действия, обязательно снимаем выборку.
При подрезке растра или других операциях системы координат растра и другого слоя (растрового или векторного) должны быть идентичными!
При работе с растрами имеет смысл сохранить их в спроецированную систему координат
Если атрибуты в shp-файле отображаются «кракозябрами», значит, надо поменять кодировку слоя. Правый клик по слою — Свойства слоя — Общие — Кодировка. UTF-8 или win-1251 обычно срабатывают. Также возможно отключить игнорирование кодировки (только для shp-файлов)
Не работайте в проектах, которые получены с сайта https://data.nextgis.com/ru/ Старые версии проектов приводят к ошибкам — например, теряются слои. Создавайте новый проект с нуля!

std::vector does have limits on how much stuff it can carry. You can query this with std::vector::max_size, which returns the maximum size you can use.

10^19 items.

Do you have 10^19 * sizeof(product) memory? I’m guessing that you don’t have ~138 Exabytes of RAM. Plus, you’d have to be compiling in 64-bit mode to even consider allocating that much. The compiler isn’t breaking; your execution is breaking for trying to allocate too much stuff.

Others have already told you what the problem is. One possible solution is to use the STXXL library, which is an implementation of STL that’s designed for huge, out-of-memory datasets.

However, 10^19 8-byte items is 80 million TB. I’m not sure anyone has a disk that large…

Also, assuming a generous disk bandwidth of 300MB/s, this would take 8000 years to write!

                    }
                output[i][j]=tmpC;
                }
            }
        cells=output;
        }

Несколько раз я обнаружил, что sizeof (cell) раз число ячеек в векторе предполагается меньше, чем vector :: max_size()

sizeof (ячейка) составляет 144 → 144 * 817 * 577 = 67882896

max_size — 268345455

Разве не должно быть достаточно места для всех ячеек, или я чего-то не хватает? Заранее спасибо!

Информация о max_size действительно появилась здесь: stl «vector <T> too long»

I’m attempting to import a schematic layout however in the DWG/DXF import menu, I get the «vector too long» error message for ~1400 entities. It’s my first time importing a DWG file, so I’m unsure how to proceed.
