core dump exporting to non existing folder

Hello Jeroen, I guess you are using inkscape-0.46 on a Linux system.
Could you please:
- get a daily version higher than svn revision 22241 and test again,
- could you also describe what would you expect? Sould the export fail on nonexisting path or should inkscape create the path?
  In my opinion inkscape should fail as a simple copy command would do. Do you agree.
  I agree inkscape must not die that way.
Regards, Adib.

Hello,

Yes, I'm using Inkscape 0.46 on Linux. I couldn't find a preview of
0.47 for Linux on the Inkscape website, that's why I couldn't supply a
report of a more up-to-date version.

As to my expection: an error telling me that the file couldn't be
created would be perfect (and returning an error code > 0); please no
auto-creation of folders. So I agree to failing as copy would do.

I'm upgrading my distribution right now, I'll try recreating the error
this weekend.

Regards,

Jeroen.

I reproduced the problem with the PPA version of inkscpae, I suppose
0.47 pre3? (though 'inkscape --version still reports 0.46+devel!). It
was build today, september 25th.

It seems issue three is resolved, but (1) and (2) still exist:

(1)
Exporting a PDF to a non-existing folder generates this:

jeroen@cerebro:/tmp$ LANG=C inkscape-devel -A pdf/test.pdf Tekening.svg
inkscape: fopen(pdf/test.pdf): No such file or directory
terminate called after throwing an instance of
'Inkscape::Extension::Output::save_failed'

Emergency save activated!
Emergency save completed. Inkscape will close now.
If you can reproduce this crash, please file a bug at www.inkscape.org
with a detailed description of the steps leading to the crash, so we can fix it.
** Message: Error: Inkscape encountered an internal error and will close now.

(2):
Exporting a PNG to a non-existing folder generates this:

jeroen@cerebro:/tmp$ LANG=C inkscape-devel -e pdf/test.png Tekening.svg
Background RRGGBBAA: ffffff00
Area 0:0:744.094:1052.36 exported to 744 x 1052 pixels (90 dpi)
Bitmap saved as: pdf/test.png

Hi,

I just upgraded to the build from oktober 4th, and the bug is still
in. Exporting to vector formats to non-exisiting folders give an
identical crash message, exporting to PNG gives a completely different
error:

jeroen@cerebro:/tmp$ inkscape-devel -P ps/test.ps Tekening.svg

I would expect a more or less identical error in all cases, telling me
the folder I entered does not exists an that I should make it my self
first.

Hi.
I wrote patch that should fix this bug. It checks the directory of path you specify, and I also changed return values of few functions in main.cpp so it is possible to return 1 on failure. You also get warning with more apt message.
I would like to ask for someone kind to review it, I am not sure about changes in main, if there was reason for the way return code was handled previosly

@Jan thanks for the patch - It looks good to me !
There has been some changes to exit codes on error (bug #993500), that conflicted with this patch.

Have modified your patch a little to compile again.

Fix committed to trunk as 11915.
