* Fix comments
* Add simulation value for SERVER_KNOBS->SNAP_CREATE_MAX_TIMEOUT
* A work version with correctness clean
* Remove unnecessay comments; debugging symbols
* Only check secondary address for coordinators, same as before
* Change the trace to SevError and remove the ASSERT(false)
* Remove TLogSnapRequest handling on TlogServer, which is changed to use WorkerSnapRequest
* Add retry for network failures
* Add retry limit for network failures; still allow duplicate snapshots on processes are both tlog and storage to avoid race
* Add retry limit as a knob and make backoff exponentail
* Add getDatabaseConfiguration(Transaction* tr)
* revert back to send request for each role once
* update some comments
This fixes a heap buffer overflow caught by ASAN, and importantly not
valgrind, since valgrind currently doesn't run on the first binary in a
restarting test. The next commit will change that so we always run
valgrind on the binary under test.
* initial structure for remote IKVS server
* moved struct to .h file, added new files to CMakeList
* happy path implementation, connection error when testing
* saved minor local change
* changed tracing to debug
* fixed onClosed and getError being called before init is finished
* fix spawn process bug, now use absolute path
* added server knob to set ikvs process port number
* added server knob for remote/local kv store
* implement simulator remote process spawning
* fixed bug for simulator timeout
* commit all changes
* removed print lines in trace
* added FlowProcess implementation by Markus
* initial debug of FlowProcess, stuck at parent sending OpenKVStoreRequest to child
* temporary fix for process factory throwing segfault on create
* specify public address in command
* change remote kv store knob to false for jenkins build

* added print lines for jenkins run open kv store timeout debug
* removed most tracing and print lines
* removed tutorial changes
* update handleIOErrors error handling to handle remote-ikvs cases
* Push all debugging changes
* A version where worker bug exists
* A version where restarting tests fail
* Use both the name and the port to determine the child process
* Remove unnecessary update on local address
* Disable remote-kvs for DiskFailureCycle test
* A version where restarting stuck
* A version where most restarting tests green
* Reset connection with child process explicitly
* Remove change on unnecessary files
* Unify flags from _ to -

* Fix Windows build
* Fix Windows build, add missing ;
* Fix a stupid bug caused by code dropped by code merging
* Disable remote kvs by default
* Pass the conn_file path to the flow process, though not needed, but the buildNetwork is difficult to tune
* serialization change on readrange
* Update traces
* Refactor the RemoteIKVS interface
* Format files
* Update sim2 interface to not clog connections between parent and child processes in simulation
* Update comments; remove debugging symbols; Add error handling for remote_kvs_cancelled
* Add comments, format files
* Change method name from isBuggifyDisabled to isStableConnection; Decrease(0.1x) latency for stable connections
* Commit the IConnection interface change, forgot in previous commit
* Fix the issue that onClosed request is cancelled by ActorCollection
* Enable the remote kv store knob
* Remove FlowProcess.actor.cpp and move functions to RemoteIKeyValueStore.actor.cpp; Add remote kv store delay to avoid race; Bind the child process to die with parent process
* Fix the bug where one process starts storage server more than once
* Add a please_reboot_remote_kv_store error to restart the storage server worker if remote kvs died abnormally
* Remove unreachable code path and add comments
* Clang format the code
* Fix a simple wait error
* Clang format after merging the main branch
* Testing mixed mode in simulation if remote_kvs knob is enabled, setting the default to false
* Disable remote kvs for PhysicalShardMove which is for RocksDB
* Cleanup #include orders, remove debugging traces
* Revert the reorder in fdbserver.actor.cpp, which fails the gcc build

I ran this command in my build directory after compiling with
OPEN_FOR_IDE. It took a few small tweaks to get it to compile, which is
outside the scope of this commit.
$ python run-clang-tidy.py -j $(nproc) -checks='-*,performance-inefficient-vector-operation' -fix
spawnProcess was waiting for 3 seconds and terminating
the child process for synchronous calls, but in the
simulator, this can lead to non-determinism, because
some cases the command can run in <3 or >3 seconds.
The fix is to increase the wait for duration to be
very long that it has to synchronously wait and get
the results or the test will timeout.
