Hi,

Still struggling with this issue,
To summarize the steps that I took to see the mongodb segfault issue,

Here are the steps I took,
Download poky (gatesgarth)

git clone https://git.yoctoproject.org/git/poky -b gatesgarth
openembedded (gatesgarth)

git clone https://github.com/openembedded/meta-openembedded.git -b gatesgarth
Add meta-oe layers to bblayers
Add mongodb to IMAGE_INSTALL

Build and runqemu  core-image-minimal using qemuarm64
After just these steps I am seeing segfault.

Anyone know about this issue/what could possibly be the issue?



If not, would also appreciate any pointers on debugging this issues,

For debugging:

Added the following to local.conf, (referenced this: https://developer.ridgerun.com/wiki/index.php?title=Preparing_Yocto_Development_Environment_for_Debugging)


IMAGE_INSTALL_append = " mongodb mongodb-dbg"

EXTRA_IMAGE_FEATURES += " tools-debug"

PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory'



#Specifies to build packages with debugging information

DEBUG_BUILD = "1"

# Do not remove debug symbols

INHIBIT_PACKAGE_STRIP = "1"

# OPTIONAL: Do not split debug symbols in a separate file

INHIBIT_PACKAGE_DEBUG_SPLIT= "1"

Then using gdb on mongod, I get:

Reading symbols from mongod...

(No debugging symbols found in mongod)

Noticed nothing is in the -dbg pkgs of mongod,  (without “PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory'”, debug files are here: /usr/bin/.debug/mongod, but  /usr/bin/.debug/mongod.debug is where gdb is expecting it, if I copy it as such I get the CRC mismatch issue below)

Removed the following from the local.conf and added the following to mongod recipe:

+ 120 INHIBIT_PACKAGE_STRIP = "1"
+ 121 INHIBIT_PACKAGE_DEBUG_STRIP = "1"
+ 122 DEBUG_BUILD = "1"

Now I see  under mongodb-dbg:

usr/lib/debug/usr/bin/mongod.debug

but when running gdb I see


warning: the debug information found in "/usr/lib/debug//usr/bin/mongod.debug" does not match "/usr/bin/mongod" (CRC mismatch).

(No debugging symbols found in mongod)




Tried the same experiment in zeus, I get,


Reading symbols from mongod...

       Reading symbols from /usr/bin/.debug/mongod...

BFD: error: /usr/bin/.debug/mongod(.debug_info) is too large (0x4d617681 bytes)



warning: Can't read data for section '.debug_info' in file '/usr/bin/.debug/mongod'

(No debugging symbols found in /usr/bin/.debug/mongod)

Am I missing something here?
Any pointers would be much appreciated!

Thanks,
Jaewon

Subject: [OE-core][gatesgarth]Mongodb segfault on gatesgarth

Hello all,

Im seeing a segfault running mongod, tested on pure upstream poky and openembedded layers (gatesgarth branch)
Any known issues here on mongod in gatesgarth?

Not a perfect test by any means but also tried mongodb version from zeus release where it was working and same issue.
hoping to maybe get some pointers in the right direction to pinpoint issue, also having some trouble setting up debug environment correctly,
Keep getting either ‘no debug symbols found’ or,  ‘the debug info found in /usr/bin/.debug/mongod.debug does not match /usr/bin/mongod (CRC mismatch)’
With what I think are all the correct flags setup to debug..

INHIBIT_PACKAGE_STRIP = "1"

INHIBIT_PACKAGE_DEBUG_STRIP = "1"

INHIBIT_SYSROOT_STRIP = "1"

DEBUG_BUILD = "1"


PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory'
Adding mongodb-dbg,   adding tools-debug

Any pointers would be much appreciated!

Thanks,
Jaewon

Perhaps first decide what you are actually trying to do. The choice is
between including debug symbols in the mongodb binary installed on the
target (e.g. modifying INHIBIT_PACKAGE_STRIP and/or
INHIBIT_PACKAGE_DEBUG_SPLIT) or splitting the debug symbols into a
separate package (ie the default) but then including that package on
the target and trying to have gdb find and use it (e.g. modifying
PACKAGE_DEBUG_SPLIT_STYLE and/or adding mongodb-dbg to IMAGE_INSTALL).
Mixing the two approaches as you seem to be doing probably isn't the
best approach...

Alternatively you can install an unstripped mongodb binary on the
target at run time using "devtool deploy-target". In that case you
might not need to mess with any of the build or packaging related
debug options at all.

Hi Andre,

Thanks for the reply, 
Yeah definitely agreed, I think near the end I had everything mixed up but initially I did try the two different routes clearly,  
will list the combos, (double checked these just now)

(inhibiting strip, checked mongod binary using objdump to make sure debug symbols are there):

IMAGE_INSTALL_append = " mongodb"
EXTRA_IMAGE_FEATURES += " tools-debug"
DEBUG_BUILD = "1"
INHIBIT_PACKAGE_STRIP = "1"
INHIBIT_PACKAGE_DEBUG_STRIP = "1"

Results in:
	Reading symbols from mongod...
	(No debugging symbols found in mongod)


(stripping, adding -dbg package, setting debug-file-directory):

IMAGE_INSTALL_append = " mongodb mongodb-dbg"
EXTRA_IMAGE_FEATURES += " tools-debug"
DEBUG_BUILD = "1"
PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory'

Results in:
	Reading symbols from mongod...
	warning: the debug information found in "/usr/lib/debug//usr/bin/mongod.debug" does not match "/usr/bin/mongod" (CRC mismatch).
	(No debugging symbols found in mongod)


devtool deploy-target was a great idea, 
but am now getting:
ERROR: No files to deploy - have you built the mongodb recipe? If so, the install step has not installed any files.

This is after doing devtool modify (had to take out a patch, Ive ran into this before, something to do with devtool/bitbake using different commands to apply patches, the missing patch wouldn’t affect what im trying to do)
and devtool build on mongodb, 
Possibly doesn’t work with scons built packages? Didn’t go too much further in trying to fix this

Any other thoughts would be much appreciated

Thanks,
Jaewon

Turns out this mongodb segfault is not unique to gatesgarth, I  see it using master as well
Anyone know of this issue?

Subject: Re: [OE-core][gatesgarth]Mongodb segfault on gatesgarth

Hi,

Still struggling with this issue,
To summarize the steps that I took to see the mongodb segfault issue,

Here are the steps I took,
Download poky (gatesgarth)

git clone https://git.yoctoproject.org/git/poky -b gatesgarth
openembedded (gatesgarth)

git clone https://github.com/openembedded/meta-openembedded.git -b gatesgarth
Add meta-oe layers to bblayers
Add mongodb to IMAGE_INSTALL

Build and runqemu  core-image-minimal using qemuarm64
After just these steps I am seeing segfault.

Anyone know about this issue/what could possibly be the issue?



If not, would also appreciate any pointers on debugging this issues,

For debugging:

Added the following to local.conf, (referenced this: https://developer.ridgerun.com/wiki/index.php?title=Preparing_Yocto_Development_Environment_for_Debugging)


IMAGE_INSTALL_append = " mongodb mongodb-dbg"

EXTRA_IMAGE_FEATURES += " tools-debug"

PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory'



#Specifies to build packages with debugging information

DEBUG_BUILD = "1"

# Do not remove debug symbols

INHIBIT_PACKAGE_STRIP = "1"

# OPTIONAL: Do not split debug symbols in a separate file

INHIBIT_PACKAGE_DEBUG_SPLIT= "1"

Then using gdb on mongod, I get:

Reading symbols from mongod...

(No debugging symbols found in mongod)

Noticed nothing is in the -dbg pkgs of mongod,  (without “PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory'”, debug files are here: /usr/bin/.debug/mongod, but  /usr/bin/.debug/mongod.debug is where gdb is expecting it, if I copy it as such I get the CRC mismatch issue below)

Removed the following from the local.conf and added the following to mongod recipe:

+ 120 INHIBIT_PACKAGE_STRIP = "1"
+ 121 INHIBIT_PACKAGE_DEBUG_STRIP = "1"
+ 122 DEBUG_BUILD = "1"

Now I see  under mongodb-dbg:

usr/lib/debug/usr/bin/mongod.debug

but when running gdb I see


warning: the debug information found in "/usr/lib/debug//usr/bin/mongod.debug" does not match "/usr/bin/mongod" (CRC mismatch).

(No debugging symbols found in mongod)




Tried the same experiment in zeus, I get,


Reading symbols from mongod...

       Reading symbols from /usr/bin/.debug/mongod...

BFD: error: /usr/bin/.debug/mongod(.debug_info) is too large (0x4d617681 bytes)



warning: Can't read data for section '.debug_info' in file '/usr/bin/.debug/mongod'

(No debugging symbols found in /usr/bin/.debug/mongod)

Am I missing something here?
Any pointers would be much appreciated!

Thanks,
Jaewon

Keep getting either ‘no debug symbols found’ or,  ‘the debug info found in /usr/bin/.debug/mongod.debug does not match /usr/bin/mongod (CRC mismatch)’
With what I think are all the correct flags setup to debug..

INHIBIT_PACKAGE_STRIP = "1"

INHIBIT_PACKAGE_DEBUG_STRIP = "1"

INHIBIT_SYSROOT_STRIP = "1"

DEBUG_BUILD = "1"


PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory'
Adding mongodb-dbg,   adding tools-debug

Any pointers would be much appreciated!

Thanks,
Jaewon

Hey Jaewon,

Once you're able to build with debugging symbols you'll see the segfault 
comes at load time from libunwind, you could either build mongodb 
without tcmalloc support (PACKAGECONFIG), or you can add 
-DNO_TCMALLOC_SAMPLES to CPPFLAGS for gperftools, if that works out for 
you send a patch to meta-oe.

Hello all,

Im seeing a segfault running mongod, tested on pure upstream poky and openembedded layers (gatesgarth branch)
Any known issues here on mongod in gatesgarth?

Not a perfect test by any means but also tried mongodb version from zeus release where it was working and same issue.
hoping to maybe get some pointers in the right direction to pinpoint issue, also having some trouble setting up debug environment correctly,
Keep getting either ‘no debug symbols found’ or,  ‘the debug info found in /usr/bin/.debug/mongod.debug does not match /usr/bin/mongod (CRC mismatch)’
With what I think are all the correct flags setup to debug..

INHIBIT_PACKAGE_STRIP = "1"

INHIBIT_PACKAGE_DEBUG_STRIP = "1"

INHIBIT_SYSROOT_STRIP = "1"

DEBUG_BUILD = "1"


PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory'
Adding mongodb-dbg,   adding tools-debug

Any pointers would be much appreciated!

Thanks,
Jaewon
