Check functions for integer overflow

I'll have a look around since I'm on it, then we can close this issue (marked for 0.9.0) and open new ones if that problem arises again.

Check functions for integer overflow

Ok, found that `edge_betweenness` uses `unsigned long long int` which can in theory overflow. So I put checks for overflow there, in PR #1436

Serialization/deserialization handlers for IGRAPH_ATTRIBUTE_OBJECT?

I have a little time, what do you wanna do with this? If this is critical, let's add the `IGRAPH_ATTRIBUTE_PY_OBJECT` and `IGRAPH_ATTRIBUTE_R_OBJECT` checks in the C serialization and then throw...

contract_vertices() should create a new graph

All the above are true, and there is perhaps an additional point about usability. Having some kind of `bool inplace` argument to functions like this is useful in higher level...

import python error

I get a similar import issue under linux, gvim8 +python3/dyn +timers. Strangely enough, completor works just fine if the repo is cloned into `~/.vim/pack/completor/start`, but it throws a bunch of...

import python error

import python error

Solves it for me, thanks so much! I just made a package for archlinux: https://aur.archlinux.org/packages/vim-completor-git/

Can confirm this issue on arch linux, Python 3.9, wxPython 4.1.0, wxWidgets 3.1.5. The proposed patch seems to fix it, thanks @stefantalpalaru !

SVG output should preserve vertex/edge attributes

@n8willis as @ntamas mentioned, there are art least two ways to get svgs out of igraph, i.e. using matplotlib or via write_svg. Which one are you trying/have you tried to...

SVG output should preserve vertex/edge attributes

Ok no immediate need, that's good to know. I recommend you also ask matplotlib whether they can include custom attributes in their SVG, that'd be the preferred route AFAIAC.
