You can use SPDLOG_VERSION to select the latest spdlog features
where available while falling back to older implementations otherwise.
Using SPDLOG_TO_VERSION() for the value to compare with is recommended.
for Example:
```c++
void sink_it_(const details::log_msg &msg) override
{
#if SPDLOG_VERSION < SPDLOG_TO_VERSION(1,4,0)
fmt::memory_buffer formatted;
#else
memory_buf_t formatted;
#endif
sinks::base_sink<Mutex>::formatter_->format(msg, formatted);
// bala bala...
}
```
Android logger (since API 30) checks the per-tag property `log.tag.<tag>` to determine if a log message is loggable. See https://developer.android.com/ndk/reference/group/logging#__android_log_is_loggable . For example, `__android_log_buf_write` for a VERBOSE message will call `__android_log_is_loggable` and return `-EPERM` if the log message will not be printed because `log.tag.<tag>` is set to `INFO`.
Instead of erroring with the following error message, the Android sink should handle `-EPERM`. It is not an error to disable a log via the run-time property.
```

* Removes special format handling for fmt. Regains test compatibility with fmt
1.10.0.
fixes#2735
* reverted std::vector back to filename_t and used pointer to array start likewise as fmt's implementation uses
* calc_filename buffer increase softened, exception is throw if buffer exceeds 4k, filename parameter renamed to match intend.
* calc_filetime based on std::put_time for simpler implementation
* Fix stdout_sink_base::log's behavior inconsistency
It will flush every time when it if not defined _WIN32, but not in
Windows family.
We viewed the commit #48d4ed9 for fixing issue #1675 .
It seems missing this flushing operation in mistake.
* Use fflush at all operating system
* Remove redundant fflush from stdout_sink_base

This method applies levels which is set by environment variable
`SPDLOG_LEVEL` to the a single controller. Usefull for loading
configuration into manually created loggers.
From the systemd.journal-fields the TID is a user defined
field passed directly from the clients and stored in the
journal. Adding the arguement in the journal send to support
that storage option in the journal.
Newlib C library (https://sourceware.org/newlib/) has a configuration
option to add tm_gmtoff field to the tm structure. Not all the
platforms supported by newlib enable this option, and spdlog doesn't
compile on such platforms due to missing tm_gmtoff field.
Fix this by checking for `__NEWLIB__` and `__TM_GMTOFF` and enabling
calculate_gmt_offset.
On musl, off_t is 64bit always ( even on 32bit platforms ), therefore
using LFS64 funcitons is not needed on such platforms. Moreover, musl
has stopped providing aliases for these functions [1] which means it
wont compile on newer musl systems. Therefore only use it on 32bit
glibc/linux platforms and exclude musl like cygwin or OSX

Use the new blocking dequeue to avoid unnecessarily waking up the
thread pool every 10s.
Fixes#2587 by replacing std::condition_variable::wait_for with
std::condition_variable::wait as a workaroung for gcc 11.3 issue 101978.
