When adding a new GEE Server with Server Accociation Manager, Fusion crashes when Server is not reachable: no status message returned from request.

Expected:
Report Failure.
Warning: Unable to contact stream data server.
Segmentation fault. in LoggingManager::AppendErrMsg(std::string const&) () from NATIVE-REL-x86_64/lib/libgecommon.so

It crashes on writing to err_str_ of LoggingManager -object in void LoggingManager::AppendErrMsg(const std::string& msg).

From @bradh:
I pushed a simple built globe, although the server wasn't installed / running.

Repro'd under gdb, here is the backtrace:

I'm only getting this bug when I specify -O2 in the build. It seems that it is caused by optimization.

Perhaps only being exposed by optimisation.

Kindly give a solution to solve this bug

tst-ccamp avatar tst-ccamp commented on April 29, 2024

@gautamp86 This is in our queue to be fixed for the first release, 5.2.0. However, the workaround for this bug is to fix the issue that is causing the utility to not be able to contact the Publish module. This could be as simple as making sure the geserver process is running or making sure your URL is correctly specified. More complex solutions might be to check the firewall and to see if you can contact the URL specified. You can see if you have connectivity by going to the URL in a web browser or by using the curl utility on the command line.

here are few suggestions to help unblock:

  1. First see why logfile is failing to open - path issue ?
    permissions issue ? race condition ? Add some try catch and printfs to surface the problem at

    earthenterprise/earth_enterprise/src/common/LoggingManager.cpp

    Line 60 in 7dbd0de

    AppendErrMsg(error_message);

My guess is that we are pushing all log messages to a local string in this situation and in optimize build, the way we are handling err_msg_ is not honored or there is no space to dump all logs.

to help find that out, add try catch around following code and print the exception.( I personally would use str::append , strcat etc. or also use a char buffer with predetermined size , depends how big is the log), you could print the length of strings before the exception occurs using both optimized and debug build and compare the lengths.

earthenterprise/earth_enterprise/src/common/LoggingManager.cpp

Line 83 in 7dbd0de

err_msg_ += "\n" + msg;

We are pushing only error messages to err_msg_ in LoggingManager. And it fails on first writing to err_msg_.
I thought that problem is related to incorrect managing of LoggingManager object in multithreading - at the time we are trying to report an error into the LoggingManager, the LoggingManager object is already destroyed.

Please, look for PublisherClient usage:
It is being created in main thread:
https://github.com/google/earthenterprise/blob/master/earth_enterprise/src/fusion/fusionui/AssetManager.cpp#L1238
https://github.com/google/earthenterprise/blob/master/earth_enterprise/src/fusion/fusionui/AssetManager.cpp#L1373

.. and then being used in push/publish thread:
https://github.com/google/earthenterprise/blob/master/earth_enterprise/src/fusion/fusionui/AssetManager.cpp#L1256
https://github.com/google/earthenterprise/blob/master/earth_enterprise/src/fusion/fusionui/AssetManager.cpp#L1384

But the simplest cases are
A. it fails when pushing database with geserveradmin.
B. it fails when pinging server in creating new server association.
While these cases look correct (object is being created and used in the same thread), it still fails on writing to LoggingManager.
So it maybe some other issue with managing the LoggingManager object.

A. Pushing database with geserveradmin use-case:
https://github.com/google/earthenterprise/blob/master/earth_enterprise/src/fusion/gepublish/geserveradmin.cpp#L432
Steps to reproduce:

  1. Build database
  2. try to push with geserveradmin when server is not running:
    geserveradmin --adddb ..

B. Pinging server when creating a new Server Association use-case:
https://github.com/google/earthenterprise/blob/master/earth_enterprise/src/fusion/fusionui/ServerCombinationEdit.cpp#L60
https://github.com/google/earthenterprise/blob/master/earth_enterprise/src/fusion/fusionui/ServerCombinationEdit.cpp#L63

Steps to reproduce:

  1. Start gefusion daemon;
  2. Run GEE Fusion
  3. Open the Server Associations Manager (Tools > Server Associations Manager) and
    try to Create/Add a new Server Association.
  4. Specify any host (note GEE server is not running on that host or it can be non-existing/non-reachable host) and try to Query it:
    it will fail when appending error message to LoggingManager.
