Crashes when device detached
Closed this issue · 17 comments
While reading data from the iPhone, if the device is detached the application crashes immediately.
Is there not any exception or crash handling? How to prevent it? Application shouldn't crash but give error instead. There seems to be problem with it.
Hi, I am happy to take a look at this problem. While it sounds familiar to an issue that was previously brought to my attention, I'm going to ask that you attach a crash report and sample repo to show this behavior. I've updated the contributing guidelines to accurately reflect what I need from you to move forward with this, thanks!
Heres the sample code. While reading file from iPhone, if device detached app crashes.
heres the crash log:

crash comes on this line in the library:
case SDMMD_AFC_Packet_GetFileInfo: {
bool should_parse = false;
CFIndex data_length = CFDataGetLength((*operation)->ivars.packet->response);
if (data_length == sizeof(uint64_t)) {
uint64_t response;
memcpy(&response, CFDataGetBytePtr((*operation)->ivars.packet->response), data_length);
if (response != 8 && response != 4) {
// this file can be accessed.
should_parse = true;
}
}
line : CFIndex data_length = CFDataGetLength((*operation)->ivars.packet->response);
Similarly if i try to fix it with null checks, there comes more crashes in other functions and thread.
I would like to have a reproducible case to test this against to determine if this is the issue i'm thinking of (accessing a bad file descriptor) or something new.
Please look at the CONTIBUTING.md file for guidelines on the requested materials. what you have posted here aren't crash logs, they are the disassembly of where it stopped. You will have to run the code outside of Xcode without a debugger attached to have it generate a crash log. You can find crash logs by opening the Console.app and looking under "User Diagnostic Reports".
Thanks!
Thank you for replying and letting me know the correct method to find crash logs.
here it is:

here's the sample project, it's same as i posted before if you detach device while reading file from device, it will crash.

Does this sample contain the changes that resolved the other issue? I want to make sure that I'm not working from an older version of the code.
No, here's the new sample with latest version of library.
https://www.dropbox.com/s/l63xtpgfxfxf5dn/SDMMobileDevice%20SAMPLE%202.zip?dl=0
And here's the new crash log from latest library.
While reading a large file, say 500mb, if you detach the device app will crash. It happens whenever in the reading process.
can you look into it this weekend?
Can you please try again with the latest commit? I haven't been able to reproduce since adding those fixes.
Yes, it's fixed now after added checks. Thanks a lot
Hi All,
Could you please share the code. i want to see the reading process using it.
Please help.
Thanks.
