use namespace aliases instead.
This makes the Objective-C code much more like what it's going to end up
being like when translated to C++: headers will include classes declared
in a namespace relative to firebase::firestore so everything else will
be named relative to firebase::firestore.
Meanwhile the using statements in the headers were causing us to miss
adding using statements in source files which was moving us away from
where we wanted to be.
* Test that shows a leak.
* Add EventListener to match Android.
* Use AsyncEventListener in FSTQueryListenerTests
* Remove FSTAsyncQueryListener
* Use EventListener throughout
* replace all references to `FSTDispatchQueue` and `FSTTimerID` with their C++ equivalents;
* remove `FSTDispatchQueue` class and related tests;
* in method argument names, replace `workerDispatchQueue` with just `workerQueue`, more similar to other platforms;
* move `Executor` and derived classes out of `internal` namespace.
* Revert "Revert "gRPC: replace Objective-C implementation with the new C++ implementation (#1968)" (#2030)"
This reverts commit ea567dca47.
* gRPC: fix bugs found during testing (#2039)
All in `GrpcStream`:
* make sure there are no pending completions when "finish" operation is enqueued;
* always finish gRPC calls;
* when connectivity changes, reset not just the calls, but the underlying channel as well.
* Revert "Partially revert "Update CHANGELOG for Firestore v0.14.0 (#2025)" (#2031)"
This reverts commit b2437b80f6.
* Update changelog for v0.15.0.
* gRPC: add gRPC wrapper classes to CMake build (#2015)
* add a C++ equivalent of `FIRFirestoreVersionString`. This eliminates the only Objective-C dependency of `grpc_connection.mm` and allows making it a pure C++ file;
* open-source `binary_to_array.py` script and use it in the build to embed `roots.pem` certificate file from gRPC into the Firestore binary. The embedded char array is then used to load certificate at runtime.
* Revert local change -- do not enable sanitizers by default
* add support for SSL disabled to `GrpcConnection` (unfortunately, there
currently is no way to verify this change actually works);
* make gRPC calls using the C++ implementation:
* make `FSTRemoteStore` create C++ streams instead of their Objective-C
counterparts;
* port https://github.com/firebase/firebase-js-sdk/pull/1041: streams
are now never recreated, only restarted;
* make `FSTDatastore` delegate server calls to the C++ implementation;
* port `MockWatchStream` and `MockWriteStream` to C++ (`FSTMockDatastore` is
still in place, because `Datastore` is not fully ported yet);
* no longer generate Objective-C gRPC service definitions from protos;
* remove all references to Objective-C gRPC client;
* check in gRPC root certificates file and load it at runtime (the check-in part
is temporary until gRPC-C++.podspec provides the certificate). This makes SSL
work.
`typeof` is only defined if you compile with GNU extensions, while
`__typeof__` is always available.
This is the Firestore equivalent of #1982.
Note that Firestore won't yet build in this mode because among other
things the Objective-C gRPC still uses `typeof`. Once we eliminate that
dependency this might become possible.
FSTDispatchQueue now doesn't contain any logic of its own and instead
just passes through all method calls to AsyncQueue (backed by an
ExecutorLibdispatch).
FSTDispatchQueue enforces serial execution, which is inappropriate for
user queue, because a user may configure usage of a concurrent queue in
settings, breaking FSTDispatchQueue invariants. Instead, use C++
ExecutorLibdispatch directly.
operationInProgress is accessed from both the main thread and from
libdispatch on some other thread. Make it atomic to avoid a data race.
Also reorder assertion checks to only access operationInProgress
after making sure the function is running on the queue.
Tested: ran unit tests using old and new versions under Thread
Sanitizer, verified that TSan reports a data race for the old version,
but finds no issues with the new version.
* lint.sh now lints Objective-C++ too
* cpplint checks system-style includes that should be user-style
This prevents it from recognizing project sources as if they were C
system headers and then complaining that they're in the wrong place.
* cpplint checks #imports and #includes
* cpplint checks that C++ system headers aren't #imported
* cpplint checks for C system headers that could be C++ system headers
* cpplint checks that Objective-C sources include their headers
Track operation in progress FSTDispatchQueue
... and allow dispatchAsync onto the worker queue even from the same
queue if an operation is not in progress. Fixes#753.
This fixes a corner case that happens when users pass us an object and
we retain that object in a block submitted to the worker queue for
processing. Users are not obligated to retain that object themselves.
This can lead to the object's destructor (or dealloc or deinit) being
called on the Firestore worker thread. If that destructor makes
Firestore API calls (most likely ListenerRegistration.remove but any are
possible) this will trigger the assertion.
[Port of https://github.com/firebase/firebase-js-sdk/commit/0fa319e5e019dd0d40ab441d2ff9f8f6d4724e43]
* Refactored FSTOnlineState tracking out of FSTRemoteStore and into new
FSTOnlineStateTracker component.
* Added a 10 second timeout to transition from OnlineState.Unknown to
OnlineState.Offline rather than waiting indefinitely for the stream to
succeed or fail.
* Removed hack to run SpecTests using an FSTDispatchQueue that wrapped
dispatch_get_main_queue(). This was incompatible with [FSTDispatchQueue
runDelayedCallbacksUntil:] since it queues work and blocks waiting for
it to complete. Now spec tests create / use a proper FSTDispatchQueue.
* Added a SpecTest to verify OnlineState timeout behavior.
* Misc cleanup:
* Renamed FSTOnlineState states: Failed => Offline, Healthy => Online
* Renamed FSTTimerIds (ListenStreamConnection => ListenStreamConnectionBackoff)
* Added ability to run timers from spec tests.
Xcode has starting warning about us implicitly retaining self references
within blocks. This commit fixes it by explicitly mentioning self. No
real changes are introduced here; this is effectively just making
implicit behaviour explicit.
Basically a port of https://github.com/firebase/firebase-js-sdk/commit/a1e346ff93c6cbcc0a1b3b33f0fbc3a7b66e7e12 and https://github.com/firebase/firebase-js-sdk/commit/fce4168309f42aa038125f39818fbf654b65b05f
* Introduces a DelayedCallback helper class in FSTDispatchQueue to encapsulate delayed callback logic.
* Adds cancellation support.
* Updates the idle timer in FSTStream to use new cancellation support.
* Adds a FSTTimerId enum for identifying delayed operations on the queue and uses it to identify our existing backoff and idle timers.
* Added containsDelayedCallback: and runDelayedCallbacksUntil: methods to FSTDispatchQueue which can be used from tests to check for the presence of a callback or to schedule them to run early.
* Removes FSTTestDispatchQueue and changes idle tests to use new test methods.
* Move all Firestore files to Objective-C++
* Update project file references
* Don't use module imports from Objective-C++
* Use extern "C" for C-accessible globals
* Work around more stringent type checking in Objective-C++
* NSMutableDictionary ivars aren't implicitly casted to NSDictionary
* FSTMaybeDocument callback can't be passed a function that accepts
FSTDocument
* NSComparisonResult can't be multiplied by -1 without casting
* Add a #include <inttypes.h> where needed
* Avoid using C++ keywords as variables
* Remove #if __cplusplus guards
This reimplements our comparison functions as C++ Comparators and then provides compatibility shims for interoperating with existing Objective-C usage.
A few specialized comparators aren't suitable for porting but only have a single usage (e.g. CompareBytes for comparing NSData * instances). In these cases I've moved them into the caller.
* Use int32_t for typeof(ID) in FSTDocumentReference
* Migrate callers of FSTComparison.h to Objective-C++
* Port comparison to C++
* Migrate usages of FSTComparison.h to C++ equivalents
* Remove FSTComparison
* Port autoid to C++
* Reimplement FSTUtil on top of firestore::CreateAutoId directly
* Migrate FSTUtil callers to directly use firestore::CreateAutoId
* Remove FSTUtil
This simplifies the import process back into google3 and allows us to add additional directories to the project without needing to update the project files for each directory we add. This shows up most clearly in the change to Firestore/Example/Firestore.xcodeproj/project.pbxproj: this no longer needs to list essentially every directory in the project as a header search path.
* Clang-format configuration for C++ files
* Add support C++-only sources to the podspec
* Podspec support for fully qualified imports
* xcodeproj changes for fully-qualified imports
* Use fully-qualified imports in Firestore sources
