| Summary | 0003093: Ardour crashes when changing zoom | ||||
| Description | When changing the zoom, ardour crashes with this message: ardour-2.8.8: gtk2_ardour/tempo_lines.cc:218: void TempoLines::draw(std::vector<ARDOUR::TempoMap::BBTPoint, std::allocator<ARDOUR::TempoMap::BBTPoint> >&, double): Assertion `_lines.find(xpos) == _lines.end()' failed. The session could not be loaded anymore, until deleting the local instant.xml, and replacing the zoom value in the ~/.ardour2/instant.xml. | ||||

I can't reproduce this, unfortunately. What is the bad zoom value in instant.xml that causes problems? If you want to debug it yourself, it looks like some faulty logic in the caching done in TempoLines::draw()... |
|
|
I've been able to reproduce it in a couple of machines (Ubuntu 9.10 with last ardour2 svn revision). cth103: have you tried to copy the attached instant.xml into $HOME/.ardour2/ ? After this open the attached session and zoom out a lot. It should crash. Thanks for the debugging tip. |

I uploaded a workaround patch: just don't draw the beat lines.... Making some tests (uncommenting the debug messages and adding some others), it appears to ONLY enter in the conditional case of "CREATING LINE", and crashed after the third time. The first time _lines is empty, and it search for xpos=0 the second time _lines have a value with key 0 and it search for xpos=1 the third time _lines have keys 0 and 1, and it search for xpos=1, that makes the assert |

i have attached an ardour file (SadSamLucky...) that was giving me the crash while zooming or horizontaly scrolling in 2.8.11 with the following error on the console: (ardour-2.8.11:5075): Gtk-WARNING **: EnableTranslation: missing action EnableTranslation Session writable based on /home/random/PROJECTS/120418_sadsamlucky/sad_sam_lucky_session3/lucky session3/ ardour-2.8.11: gtk2_ardour/tempo_lines.cc:218: void TempoLines::draw(std::vector<ARDOUR::TempoMap::BBTPoint, std::allocator<ARDOUR::TempoMap::BBTPoint> >&, double): Assertion `_lines.find(xpos) == _lines.end()' failed. Aborted disabling Show Measures works as a workaround. |
|
|
The problem also exists in Ardour 3 (svn 13991). The crash appears if the value of the zoom attribute in the Editor tag exceeds 30000 in instant.xml This line works: <Editor id="11" mixer-width="Wide" zoom-focus="ZoomFocusMouse" zoom="30000.000000" ... This line crashes: <Editor id="11" mixer-width="Wide" zoom-focus="ZoomFocusMouse" zoom="30001.000000" ... It seems to me that somebody made the decision "30000 units is enough for everybody." ;-) |
|
|
As of rev14015 it seem fixed in Ardour3. |
|
|
ah, great, i wondered if that change would fix this issue. thanks for the prompt follow up. |
|
|
see notes. |
|
|
Just a note: Since this issue was originally a 2.0 issue, a backport should be considered... |
