----------------------------------------------
Summary: Exceptions not correctly re-thrown in the tx manager
Key: GEODE-8830
URL: https://issues.apache.org/jira/browse/GEODE-8830
Project: Geode
Issue Type: Bug
Components: native client
Affects Versions: 1.13.1, 1.13.0, 1.12.0
Reporter: Mario Salazar de Torres
Under several transactional scenarios exceptions are converted from its more
specific type to *Exception* type within the internal code of the native
client. The scenarios are the following ones:
# Whenever a transaction commit conflicts the native client user would expect
a *CommitConflictException*, but instead the user can only catch an exception
of type *Exception*.
# Whenever a transaction prepare conflicts the native client user would expect
a *CommitConflictException*, but instead the user can only catch an exception
of type *Exception*.
# Whenever rollback/prepare/commit is executed with no transaction ongoing the
native client user would expect an *IllegalStateException*, but instead the
user can only catch an exception of type *Exception*.
----
*Example:*
{code:c++}
auto tx_manager = cache.getCacheTransactionManager();
// First transaction starts here
tx_manager->begin();
region->put("key", "A");
// First transaction is suspended before doing the commit
auto& tx_id = txm->suspend();
// Second transaction starts here
tx_manager->begin();
region->put("key", "B");
tx_manager->commit();
// After successfully committing the second transaction, the first transaction
is resumed
tx_manager->resume(tx_id);
try {
tx_manager->commit();
}
catch(CommitConflictException& ex) {
// This is what should be in the output in this example
std::cerr << "A conflict occurred while committing the transaction!" <<
std::endl;
}
catch(Exception& ex) {
// However, as there is some issue with exception handling, this is what's
currently shown
std::cerr << "An unknown exception occurred while committing the
transaction!" << std::endl;
}{code}
