| Summary | 0004763: session file corruption (negative region lengths in playlist) leading to runaway memory usage | ||||
| Description | when i try to load the attached session, ardour starts gobbling up all available memory (16gb ram, 10 of which are memlockable for this user), then aborts after throwing a std:bad_alloc. post-mortem is attached. the issue is 100% reproducible, and i'm stumped. did go through the session file for obvious inconsistencies, but couldn't find anything amiss... | ||||
| Steps To Reproduce | start jack, start ardour3, load the attached session file. | ||||
| Tags | No tags attached. | ||||

just verified i can reproduce this bug with just the session file, in the absence of sound and peak files or anything else in the session directory. |
|
|
with all regions commented out in the session file, the problem persists. with all playlists commented out, the session loads. looks like there is a region length in the playlists that got corrupted: Region name="Bala L L-22.38" position="948409829" length="9223372035906365978" the same martian length crops up in all playlists that have been touched by the last edit operation... will try to salvage the session file and report back... |

ok, i've edited the session file by hand to weed out the obvious errors (see *-edited.ardour), and now i'm stuck with a segfault related to automation drawing, probably because i guessed the region length wrong. |
|
|
you've already moved past the point where my debug line is really useful. and it was also wrong anyway, because i put in the code that shows the start, not end of the region. how easy is it to end up with a session in this condition? |
|
|
don't know, this is a first. the session is complex - 24 channels, two recording days, 2k8 regions. and then i started editing, which was probably not a good idea. there was no crash or any other oddity. just saved a snapshot, and the next morning, pooof. i do have regular snapshots, so i could sort of bisect the session. will try that next. as soon as i know more, i'll fix the title of this bug, the memory explosion seems to have been justified - it was the playlist length field after all... |
|
|
<nettings> las: btw, i've just had another session state corruption, happened while copying a range out of a number of selected tracks and moving it backwards in time. standard situation: first note is weak, so cut out one from a few bars into the groove and move it to the beginning. <nettings> same situation as the first breakage, and it creates a spurious region in an empty track. i'm uploading a screenshot. this is based on the old session, which was cleaned by hand after the initial corruption. |

it seems the bug is triggered by selecting non-consecutive ranges of tracks. the bogus regions with negative lengths (which are ultimately causing the crashes) are in those tracks which were _not_ selected for copying. |
|
|
the root cause of this behaviour was a previously corrupted session file, so i've renamed the bug. |
|
|
Do you have a recipe by any chance? |
|
|
not really. as mentioned above, the following sequence of actions triggered the problem, at least twice: select a short range, spanning multiple tracks. the selected tracks are not consecutive in the current track order. the tracks were selected using ctrl-leftclick, or a combination of rubberband selection and ctrl-leftclick. most tracks are mono, but one or two are four-channel. copy the ranges. move the edit point back in time. paste the ranges. now, an error related to negative index numbers in BBT pops up. the session file will now have some ranges with very big length numbers in the playlist section. crossfades and other automation might have spurious negative numbers. disclaimer: this session might have been dodgy to begin with. as you can see, it's huge (two long days of recording into it), and there was at least one ffado-related jack crash during that time. i'll be on the lookout for similar issues, but unless other people are seeing similar issues, i wouldn't treat it as too urgent... |
