segmentation fault if you entered a category ending with :

[tordik]

Hi,

I have currently an "Segmentation fault (core dumped)" when I open some lines previously categorized, and the application stops (crash).
Actually it seems to be linked to events with a specific account and category ("vacances"), but difficult to be completely sure.

I get the issue either using reports, display details, open some a line from the specific category (that I know to cause the trouble).
I get the same result, going trough the details of the account, and open line previously managed.

I have the issue with Homebank 5.1.8 on GTK+ 3.22.30 (fedora)
I tested on my other computer Homebank 5.1.8 on GTK+ 3.22.26 (CENTOS): same result.
I don't have the issue on Windows (freshly downloaded) - at least on the line I tested and that I knew it crash on my linux systems.

Can you help to analyse the cause ?

Thank you
Antoine

[Maxime DOYEN (mdoyen)]

it seems in the same area than 1771326, I am very interesting in finding this out, hope you can help.

2 solution here:
a) can you compile from source and going into a further debugging, following my last message into 1771326 ?

b) provide you file anonymized (or not) to homebank email address at the bottom of this page:
http://homebank.free.fr/en/support.php

let me know if you need help

[tordik (toine-p)]

Hi,
I compile the homebank with instruction in case 1771326 (and remove in parrallel homebank provided by fedora). I suffer then a lot of icons / menus missing in homebank (maybe some customizations / parameters of GTK stuff by Fedora )

Anyway, I finally arrived to reports with details, and reproduced the exact same issue:

[Maxime DOYEN (mdoyen)]

yes thanks.
what surprise me (and explain the crash) is that you have a category 'Vacances:(null)'
which should not happen (you normally can input : into the category)

can you open your xhb file file a text editor and have a look for any others like this,
just search for : , normally you don't have

Do you remember how you input that category ?

[tordik (toine-p)]

Hi,
Correct, and I don't know why it is NULL. However, all category "vacances" are crashing Homebank (from what I remember), I will reconfirm.

Also, but I tried a preliminary test erasing the last 6 month of history in the xhb file (and then erasing this "NULL" category), but the result was the same. I will reconfirm that also.

However, I don't get the characters I need to look for? ":" and "," ?
I do have ":" in "wording="VIR SEPA EMET : XXX"
few "?" in comments I wrote, "info= XX? "
I don't have ": ,"
I can not find Vacances:(null) (how to look for?)

[Maxime DOYEN (mdoyen)]

ok.
bug reproduced, and know what happens and how you input that

[tordik (toine-p)]

But the strange point was that it did work on Windows, but crash on Fedora.

[Maxime DOYEN (mdoyen)]

strcasecmp might be more compliant to NULL on Windows than on GNU/Linux

[Maxime DOYEN (mdoyen)]

here's how to workaround this crash by editing a little your xhb file:

a) search for any <cat like this (there is no name="" attribute):
  <cat key="2" parent="1" flags="1" />
  (key and parent can have different value of course)

b) and change it by adding a name="" like this :
  <cat key="2" parent="1" flags="1" name="dummy" />

c) open your file, check, it should work.

then later on:
- you could remove/merge those dummy subcategories
- and of course never enter another category ending with a : until I prevent doing so and the associated crash as well.

[tordik (toine-p)]

Hi Great! It works. I do had a line with missing "name=xx", I corrected and no more crash.
I don't know how it happen to have this subcategory NULL (I am using the same file account since 2011... )
But Thank you!
