* NetworkTableInstance: set handle to 0 after destroy
* Fix multiple notifications of local values
* Detect mismatch between handles
* Server: fix setting min period when no topics
* Limit maximum number of subscribers/publishers/listeners
This helps find resource leaks and prevents them from causing excessive
slowdowns/crashes. The limit on each is currently set to 512.
* Don't use std::swap in move operation
- In both C++ and Java, add listener functions to Instance class (same as NT3 provided)
- Add WaitForListenerQueue functions (same as NT3 provided)
- Move Java non-poller implementation to Instance (previously only handled single instance)
- Change C++ listeners to take non-const references for subscribers etc to help avoid footguns from use of temporary objects (also add doc comment)
- Fix Preferences making .type persistent
This avoids the need for explicit value() calls (as compared to using
DoubleTopic). The unit name is published as the "unit" property.
Implementation note: the test needs to be in wpilibc because ntcore does
not depend on wpimath.
* TopicListener: Fix Add() return values
* Update PubSubOption poll storage documentation
* Update NetworkTableEntry::GetValue() doc
* Add documentation regarding asynchronous callbacks
* Unpublish entry: set publisher to nullptr
* Implement ValueListenerPoller default constructor
* Remove SetNetworkIdentity, make parameter to StartClient
* URI-escape client ID, improve error message
* Add connected message with client id; also improve disconnected message a bit
* Handle SetServers either before or after StartClient
* Fix client use-after-free; also delay reconnect after disconnect to rate limit
* Don't re-announce to already subscribed client; we especially don't want to send the last value again
* Always accept in-order sets, only use timestamp for tiebreak
* Fix LocalStorage::StartNetwork race
* Remove unused/unimplemented function
Also:
* [glass] Remove debug print
* [glass] Fix mpack string decoding
* [cameraserver] Fix up startclient
This is enabled by the C++20 __VA_OPT__ feature.
Uses of "{}" format string were updated.
Some warning suppressions were required for older clang versions.
Also improve codegen of wpi::Logger::Log(), frc::ReportError(), and frc::MakeError();
these generate better and less redundant code if they use fmt::string_view for the
format string instead of templating on it.
* Use explicit this capture required by C++20
* Use C++20 span
* Replace wpi::numbers with std::numbers
* Fix C++20 clang-tidy warning false positive in fmt
* Remove ciso646 include since C++20 removed that header
* Fix global-buffer-overflow asan warnings in ntcore tests
* Add DIOSetProxy constructor to HAL
* Upgrade MSVC compiler to 2022
* Bump native-utils to 2023.2.7 (changes to std=c++20)

* Fix C++ Publisher and Subscriber move assignment
* Fix Publisher comment typo.
* Publish: check that properties is an object.
Print a warning, but still publish, just with empty properties.
Add error print for unassigned type publish.
* Return boolean from SetProperties
* Document exception-throw in Java for invalid JSON.
Checkstyle naming conventions were changed to allow most of what's in
wpimath. Naming rules were disabled completely in wpimath since almost
all suppressions are for math notation.
fmt removed fmt::make_args_checked since it's no longer needed for
constexpr format string checks.
fmt deprecated implicit conversions from enums to integers in format
arguments, so I added explicit static casts.
Unlike std::string and std::string_view, this substr() allows a start
greater than the length of the string, in which case an empty string
is returned. This matches llvm::StringRef behavior.
These relied on the OnStart and OnExit callbacks which were not present
in the wpiutil common CallbackManager code. Add support for these and
fix up other use cases.
Also fixes notifications to correctly filter on event kind.
This fixes a breakage caused by #3133.
I generated lists of includes and uses via
`rg -l deprecated.h | sort -u` and `rg -l WPI_DEPRECATED | sort -u`
respectively. If a file was in the first list but not the second, the
include was unused. If a file was in the second list but not the first,
the include needed to be added.
I started with the output of styleguide#217, then renamed a few classes
to fix compilation.
ntcore's StorageTest needed some manual renaming since it put the Test
word in the middle instead of at the end.
One limitation of wpiformat is test cases that were only named "Test"
were unmodified, and an error was generated. These test cases were
manually given more descriptive names:
* TimedRobotTest mode test cases had "Mode" appended to the name. Java
tests were renamed to match.
* UvAsyncTest and UvAsyncFunctionTest cases were given alternate names
Now that there are only 16 instances, store them all statically.
Make tests more reliable by using different ports for each connection in listener tests.
This upgrade uncovered two issues:
ntcore wasn't forcing C++17, which caused a linker error with googletest
Matcher symbols:
```
undefined reference to `testing::Matcher<std::basic_string_view<char, std::char_traits<char> > >::Matcher(std::basic_string_view<char, std::char_traits<char> >)'
```
test_span.cpp wasn't including <algorithm> to use std::sort() and
std::is_sorted().
The non-NT portion has been moved to wpiutil.
The NT portion has been moved to ntcore (as NTSendable).
SendableBuilder similarly split and moved.
SendableRegistry moved to wpiutil.
In C++, SendableHelper also moved to wpiutil.
This enables use of Sendable from wpimath and also enables
moving several classes from wpilib to wpimath.
Some valid warnings like throwing NullPointerException or using a for
loop instead of System.arraycopy() were fixed.
Abstract classes marked with PMD.AbstractClassWithoutAbstractMethod were
made concrete because they already had protected constructors.
Fixes#1697.
- Twine, StringRef, Format, and NativeFormatting have been removed
- Logging now uses fmtlib style formatting
- Nearly all uses of wpi::outs/errs have been replaced with fmt::print() or
std::puts()/std::fputs() (for unformatted strings).
- A wpi/fmt/raw_ostream.h header has been added to enable
fmt::print() with wpi::raw_ostream
Use ghc::filesystem as fill on older GCC (e.g. RoboRIO).
This can be removed once all GCC platforms have upgraded to 8.1 or later.
File open functionality has been retained from LLVM but moved to "fs" namespace
and tweaked for improved consistency with std::filesystem (e.g. error_code is
passed by reference instead of returned).
Also update WPILibC's Filesystem functions to return std::string.
