Re: [Qgis-developer] Plugins approval
Is there a real problem we are trying to solve with this? I am not sure, each plugin will belong to exactly one menu and the rules can technically be enforced. IMO They can as well have some entries in two different menus. Or require a totally new menu (although there need to be really good reasons for this). This discussion seems related to the category vs. tags discussion for plugins, which we had some time ago, where I also think, that the category solution is not flexible enough in comparison to the possibilities offered to plugin authors by the extensive QGIS API. Therefore, I would propose not to implement hard rules (like specifying the menu in metadata) but leave all the options to the plugin author and have some intelligent soft rules, which can be considered for each case individually, and eventually be discussed with the plugin author in the approval process.

Thanks for your comments. I'd like to keep things simple at this stage: what I think we should avoid (and this is easy to do) is having new plugins going to the Plugins menu, instead of the appropriate one. Rationale: * keeping a tidy interface * make it predictable for users where to find a command. I suggest to check this for each new plugin, and ask the author to chenge it if necessary before approval.

Re: [Qgis-developer] Field calculator does attribute changes silently
Hi Matthias I remember there was a performance consideration leading to the emitSignal parameter in changeAttributeValue. But I don't know if it is still needed, seems to be only used from field calculator, offline editing and a label tool. So +1 for your proposal. Regards, Marco On 06.01.2014 14:01, Matthias Kuhn wrote: Hi, Currently,when the field calculator does changes to attributes (modification, not adding a new column) it blocks signals of the vector layer while doing this. This leads e.g. to bug #9268 [1], that the attribute table is not updating properly. The fix would be very easy (i.e. remove the blockSignals() call) but I wanted to ask first, if there is a reason not to do this. The main reason why I am afraid is, that apart from the blockSignals() call, there is also the paramter emitSignal specified as false in the call to vectorlayer-changeAttributeValue(). This parameter is currently not working, so I suppose that the blockSignals() call was introduced as a workaround. However, there was a good reason, to block the signals explained in issue #7071 [2], fixed by Jürgen, that at the time when we only supported one iterator per layer, emitting this signal would break the update process and produce only partially updated results. This is fortunately no longer the case, so this reason can be considered obsolete. Another reason which I could imagine (but I have no proof of) is that for big layers, emitting the signal for each feature can possibly take a long time. However, if this is actually the case we should rather think about batching the signal or fix unperformant consumer slots of this signal. Be aware, that at the current state, there is no possibility, neither for plugins nor in QGIS core, to get reliable push-notifications when an attribute changes. So my proposal is: * Remove the blockSignal calls and let attribute changes always be promoted * If there are problems introduced, lets fix the problems instead of working around them at the cost of unreliability * Don't fix the emitSignal parameter for QgsVectorLayer::changeAttribute and deprecate it for future removal.

Looking at reports in general some kind of programming will always be needed to generate an individual report because the data structure is individual, too, so I think it will always be something for specialists. An idea to start with would be to create a new element in Composer that makes simple calculations like sum or average on a field: Choose layer - choose field - choose what to do.

Hi, +1 from me for reporting tool for QGIS. This is important feature we missed in QGIS. I proposed this idea some time ago (about year or two) but didn't get much feedback. Now situation changed, much more peoples are interested in such tool. In terms of implementation, there is not only Jasper (which is Java), but also other more or less powerful reporting tools/engines. For example, there is a NCReports (C++/Qt), it has both commercial and opensource versions (but AFAIK opensource one is a bit unmaintained), there is OpenRPT (also C++/Qt, but without runtime report designer), QtRPT (experimental), Exaro. Also there is a wonderful FastReports report engine, but unfortunately it AFAIK Windows only, there is an opensource crossplatform version called FreeReports. 2014/1/7 Paolo Cavallini cavall...@faunalia.it: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Il 07/01/2014 12:06, Andreas Neumann ha scritto: Hi, Personally I think that it is time to start implementing a reporting within QGIS itself.

[Qgis-developer] qgis-server segfaults policy
Hi, I started working on qgis server, trying to split GetStyles from GetStyle as discussed yesterday.

[Qgis-developer] Reporting engine
Hi, I am starting a new thread on the reporting engine. As it generates a lot of interest and the content is not related to attribute tables anymore ... I think it would be good to schedule a meeting at the next Hackfest in Vienna. Meanwhile it would be good to find out if the existing C++/QT based solutions could be used from a licensing and from a technical point of view. We could also start collecting requirements in a wiki. Or if it may be wiser to write something from scratch based on our existing API and the current Atlas functionality. The question with the separate tools and libraries is if they could be well integarted. Ideally the GUI would be in separate panels and toolbars inside the QGIS print composer and not with a separate tool or window. Could someone open a wiki page for collecting the requirements and facts about existing reporting tools? I am not too familiar with the new QGIS infrastructure yet - just read you are migrating the content currently. Thanks, Alex, for listing the C++ based options! Its a good start. I had a very quick look on some of them. OpenRPT is GPL, which is nice, but last update at Sourceforge from 2011 - not so nice. Or is QtRPT the followup project? Exaro does not show a lot of activity - last update 2009? Same for FreeReport (last update 2002). I have severe doubts if a project hadn't been updated for more thant tow years NCReports seems to be quite powerful and advanced but I have doubts about the license. Something to find out/negotiate.

Re: [Qgis-developer] Plugins approval
Hi Paolo and Jonathan, Thank you for sharing your thoughts. We should encourage plugin-authors to write a good get-started section in the description in their metadata. Or we could include yet another getstarted metadata section. I remember, I discussed another key website with Borys, which would be shown in a frame in the plugin description page. This could be used to show even pictures in a description. Or we could just embed the URL listed in homepage. Why I think this is a better idea: * E.g. The processing plugin creates a new menu, this would not fit into the previously described scheme. (But the scheme could be adapted to contain an array of menu entries) * Plugins can have more than one menu entry (Sending them back to the plugins menu would totally fail to fulfill the requirements listed by you) * Evenmore: There may as well be plugins with no menu entry at all. (E.g. You could write a plugin just to add new attribute editor fields) Optimally we should have a good guideline where we can point people to. And the plugin builder plugin should already help people to get this done. So I would not say anything to fix that is a good approach, but a well-designed solution will be very welcome. The other (technical) option which I can think of would be to define access rights or hooks which a plugin can acquire in the metadata section and then the app will be delivered with these. So a plugin could acquire the Register a new toplevel menu item or the Register a vector menu item or the Register a new attribute editor widget or the Register a new raster pipe function hooks. Smartphones use something like this for their permission management. While this offers some advantages (you can exactly list, what the plugin will do) it seems a bit over-engineered for this problem IMHO. And it would require to rewrite all plugins :) Therefore my preference: Solve it with human sense instead of technique.

Thanks for your comments. I'd like to keep things simple at this stage: what I think we should avoid (and this is easy to do) is having new plugins going to the Plugins menu, instead of the appropriate one. Rationale: * keeping a tidy interface * make it predictable for users where to find a command. I suggest to check this for each new plugin, and ask the author to chenge it if necessary before approval.

Re: [Qgis-developer] problem with forms and python init
Hi Enzo,
I return to this old discussion because I noticed that the problem that I
described still remain the same when I use Qgis 2.0. On the contrary when I
use Qgis 2.1 all works fine.
I didn't full understand this problem previously because I use qgis 2.0
on my works PC and and 2.1 with linux on my laptop.
Anyway I resolve the problem whit Qgis 2.0 using your tip of QgsFeatureRequest
with NoGeometry flag, so the mail is just to keep track of the problem.
thanks again.

2013/12/21 Enzo Ciarmoli enzo.ciarm...@csi.it:
nevertheless the problem remain the same: if i try to load the data
from a table without geometry, values for i.attributes()[1] remain
empty.
Hi Luca,
I tried your sample code and it works... I don't know what's wrong in
your
situation...
If your problem remain the same,
I could suggest you to use QgsFeatureRequest with NoGeometry flag
(see Detailed Description in:
http://www.qgis.org/api/classQgsFeatureRequest.html )
Example:
layer = QgsMapLayerRegistry.instance().mapLayersByName('your_table')[0]
iter =
layer.getFeatures(QgsFeatureRequest().setFlags(QgsFeatureRequest.NoGeometry))
for feat in iter:
print feat.attributes()
print feat.attributes()[0]
print feat.attributes()[1]
Ciao!

Adding to QgsExpression doesn't make much sense as QgsExpression is only based on a single feature.

Then it'd be possible to generate expressions which could compare individual features to the entire layer - eg testing if a value is greater than the layer mean, etc... There's already a bunch of non-feature specific functions in QgsExpression and a lot of demand for even more.

This should remove the problem with too many connections. It limits the maximum number of concurrent connections from one QGIS instance to four. Also, when the connections are not used for some time, they get closed to save resources (right now it is after one minute). Please test and let me know if things work better now.

You would need layer on top of if with functions that can do aggregates. - Nathan I would love to see layer stats in QgsExpression. Then it'd be possible to generate expressions which could compare individual features to the entire layer - eg testing if a value is greater than the layer mean, etc... I could imagine aggregate functions as another layer on top of QgsExpression instead of implementing the support directly into QgsExpression. There could be a class that would deal with the whole layer and register the aggregate functions to instances of the expression engine where appropriate. This would keep the design clean. There's already a bunch of non-feature specific functions in QgsExpression and a lot of demand for even more. One thing I am worried about is the increasing number of custom functions which make sense just in a particular context (e.g. in composer). The issue is the fact that registering of functions and setting special columns is done with static functions, therefore affecting all instances of QgsExpression. Functions and special columns valid in a particular context (field calculator, rendering, ...) should be made available only for instances where it makes sense. I can imagine this as having expression context classes that would extend the basic set of functionality of QgsExpression with more functions. We could have contexts for: - field calculator: $rownum - rendering: $scale - composer: rendering context + $map - atlas: composer context + $page, $numpages, ... - aggregate: min(), max(), avg(), sum(), count() These contexts could be passed as a second parameter in QgsExpression constructor. Moreover, I am still not convinced that we need special columns in QgsExpression - they should be handled as functions with zero arguments to keep things simple. I think we should fix these issues before adding more extensions to QgsExpression, otherwise we may get into trouble in the future, especially if multi-threaded execution will get more common. For example, printing atlas pages in parallel would make things like $page or $feature vulnerable to run conditions - e.g. sometimes it could print everything correctly, other times all pages could have the same number!

Re: [Qgis-developer] QGIS Multi-threaded Rendering
Hi Martin, I also confirm I don't have any more trouble with too many connections. This works like a charm Cheers, Denis On 07. 01. 14 22:23, Andreas Neumann wrote: Hi Martin, I tested it and can confirm that the PostgreSQL pooling works fine and fast now.

In general my PostgreSQL based projects with many layers freeze after a very short time, while the SpatiaLite based projects work very nicely. Too many PostgreSQL connections? Can we limit the PostgreSQL connections or can you better re-use existing connections? A quick followup - today I have pushed some changes that introduce a connection pool for PostgreSQL. This should remove the problem with too many connections. It limits the maximum number of concurrent connections from one QGIS instance to four. Also, when the connections are not used for some time, they get closed to save resources (right now it is after one minute). Please test and let me know if things work better now. I will probably also look at pooling of SpatiaLite connections - right now the queries within SQLite are serialized, so within one SpatiaLite database you will not see any performance gain with parallel rendering.

[Qgis-developer] How wiki can be of help (or harm)
A nice story, with happy ending: * long ago, Etienne and I started a wiki page about possible improvements on the colour ramps * in the meantime, Etienne implemented most of the items * as it often happens, the page got forgotten, buried among hundreds of others, with a bunch of solved and unresolved issues * luckily, the recent wiki cleanup forced me to reexamine it, and together with Etienne we cleaned it up, moving all remaining issues to tickets * this prompted Etienne to solve a trivial, yet important from a user point of view, long standing issue (in fact, there may still be another ticket hanging out). A trace here: https://github.com/qgis/QGIS/pull/1059#issuecomment-31800254 In short: cleaning up the wiki is a Good Thing.
