Programs closes when you try to add an instrument that is already on the pattern

[schirrel]

I know that the user must know what instruments it got on the pattern, but sometimes it occur to forget that they're there, for e.g. when you have much instruments, so when you try to add this instrument the programs exits and leave no message for the user or even save the project

Hi! Which version of hydrogen (on which operation system) are you running?

[thijz]

are you running 32 or 64 bit, and what are the specs of your pc ?
do you have a reliable way to reproduce this ?

[schirrel]

I'm using ubuntu 14.04 in a dell inspiron 15r, 8gb ram, 1t disk, i7. My hydrogen version is 0.9.6. The only way i can reproduce is if i record the screen. I'm not much into logs and stuff, so if its happening can it be saved in a log file? Where did the program saves it?

[thijz]

from an old bug report (assembla ticket) :

Hydrogen 0.9.5
Ubuntu 10.04 64bit
Jack1 @ 128/48000*3 (8ms)

Everytime I add or delete instruments I have to keep my fingers crossed because Hydrogen easily locks up on these operations. Adding instruments works most of the time but if I click the menu item Instruments - Add instrument just a wee bit too fast after one another if I'd like to add 2 or more instruments H2 locks up. Deleting instruments is even iffier, I basically try to avoid it as much as possible, 9 out 10 times H2 stalls and I have to force quit or kill it. I have the idea that it relates to DSP or CPU load. If I work with just H2 adding and deleting instruments works pretty much ok, If I have more audio applications open (a normal session includes about 6 or 7, DSP load around 50% on a quad core system) H2 starts to get obnoxious.
I know this description is not very precise but then the freezes are pretty random. If more info is needed I'm happy to provide it.

Best,

Jeremy

i added the previous comment because this seems related
i have seen hydrogen (early 0.9.6 code) crash when adding instruments, but only on an old (slow) laptop
on my laptop (core i7, 8G ram) i have never seen this

putting these different reports together does seem to point in the direction of CPU load. race condition maybe ? could it be 32bit <> 64bit ?

AFAIK the only way to get a log from hydrogen is to start it from a terminal, set the correct verbosity level and pipe the output to a file. something like this :
hydrogen -V 0xHHHH > hydrogen.log

[schirrel]

Hi, i tested it now, and no crashs has happened. I dont know why, but starts to work fine now

[schirrel]

hi jasane
can you please retest this on the lates 0.9.7 github code and let us know if this issue is still present ?
thanks!

I'm closing this ticket now since it seems to be not possible to reproduce the problem..
