dump_syms reports this translator cannot yet translate DWARF expressions to Breakpad postfix expressions #475

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. get breakpad and build it
svn checkout http://google-breakpad.googlecode.com/svn/trunk/  breakpad
./configure && make
2. create and build breakpadtest.cpp
g++ -I~/Public/breakpad/src -O0 -g -Wall breakpadtest.cpp 
-L~/Public/breakpad/src/client/linux -o"breakpadtest"   -lbreakpad_client 
-lpthread

3. run the test program, analyze dump file.
$ ~/Public/breakpad/src/tools/linux/dump_syms/dump_syms breakpadtest > test.sym
breakpadtest, section '.eh_frame': the call frame entry at offset 0x7c uses a 
DWARF expression to describe how to recover register '$ebx',  but this 
translator cannot yet translate DWARF expressions to Breakpad postfix 
expressions
breakpadtest, section '.eh_frame': the call frame entry at offset 0x7c uses a 
DWARF expression to describe how to recover register '$esi',  but this 
translator cannot yet translate DWARF expressions to Breakpad postfix 
expressions
$ head -n1 test.sym
MODULE Linux x86 D5702C95B22469CE18793A30C1C636C80 breakpadtest
$ mkdir -p ./symbols/breakpadtest/D5702C95B22469CE18793A30C1C636C80
$ mv test.sym ./symbols/breakpadtest/D5702C95B22469CE18793A30C1C636C80
$ ./breakpadtest 
Dump path: /tmp/2c54ac0a-7e1a-677b-47eb8015-29f3153a.dmp

$ mv /tmp/2c54ac0a-7e1a-677b-47eb8015-29f3153a.dmp test.dmp
$ ~/Public/breakpad/src/processor/minidump_stackwalk test.dmp ./symbols

What is the expected output? What do you see instead?
expect minidump_stackwalk display call stack from the dump file, but it just 
prints some warnings.

yeah, have that same on 3.7.5-1-ARCH #1 SMP PREEMPT Mon Jan 28 10:03:32 CET 
2013 x86_64 GNU/Linux archlinux. Any ideas how to handle this?

Has there been any traction on this? Anyone working on a fix?

No one is working on this. It's generally not a problem in practice, since most 
unwind expressions don't use them.

I had this problem initially when I tried to follow the linux example.
However, when I wrote a script that followed LinuxStarterGuide exactly,
it worked.
I've attached the script; does it work for you?

i have the same issue.. i try your script but it doesn't work for me

Original comment by federico...@gmail.com on 7 Jan 2014 at 9:42

GoogleCodeExporter commented 9 years ago 
@daniel.r...: i guess your script only checks if there is some output from the 
minidump_stackwalk utility and doesn't check if the output is symbolized. The 
issue (atleast I have) is that is NOT symbolizing even though the binary GUIDs 
are matching.

@breakpad_team: does it check anything else apart from module GUID for matching 
or picking up the right symbol file?

Any help is appreciated.

GoogleCodeExporter commented 9 years ago 
The SimpleSymbolSupplier implementation only considers the debug file and debug 
id when constructing the symbol filename:
https://code.google.com/p/google-breakpad/source/browse/trunk/src/processor/simp
le_symbol_supplier.cc#142

Nothing in the Breakpad processor actually reads the MODULE line from the 
symbol file.

Please correct me if I am wrong and pardon my limited knowledge. So does it 
mean that this will not run in production/release mode, since there is no 
detereministic way to figure debug id on server side (or is there any)?

Thanks for your help and leads.

Btw I am using this for my android application and running the tools on a linux 
box.
