Summary:
Solaris support was contributed by outside users starting with d78c6b28c (2016), and no project CI has ever run on Solaris. The last Solaris-motivated change was c76688745 (https://github.com/facebook/rocksdb/issues/4012, June 2018). Four months later, d6ec28870 (https://github.com/facebook/rocksdb/issues/4226, 5.18) gave PerfContext a user-declared destructor while the Solaris-only definition was still `__thread PerfContext perf_context_`, which GCC rejects, so the Solaris build has not compiled since. fd00f39f9 (https://github.com/facebook/rocksdb/issues/8117, 2021) then renamed that definition to `perf_context` while keeping
`#define perf_context (*get_perf_context())` in perf_context_imp.h, so the definition expands to `thread_local PerfContext (*get_perf_context());`, an error still present today. The Solaris-only paths are dead and untestable, yet still attract new carve-outs.
Because Solaris support is apparently unused and complicating things, this change removes all OS_SOLARIS / SunOS handling from the build (Make, CMake, build_detect_platform, INSTALL.md), the portability layer and Env (endianness, gethrtime, directio, stack trace), the perf_context macro and destructor carve-out, Solaris-only test workarounds and exclusions, and RocksJava's Environment.isSolaris() and Solaris JNI library naming.
Not Solaris-specific and kept: SPARC unaligned-access handling in util/coding.h, sparc64 in Makefile machine lists (Linux/OpenBSD), and sparcv9 in RocksJava Environment.is64Bit(). Third-party sources are untouched.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/15449
Test Plan: On non-Solaris platforms every removed condition was either an OS_SOLARIS-only branch or a `!defined(OS_SOLARIS)` term that was always true, so the code compiled is unchanged and the CI matrix covers it. The Solaris breakage was confirmed by syntax-checking monitoring/perf_context.cc with -DOS_SOLARIS (GCC 11, stub sys/isa_defs.h) at each commit touching the perf_context files from c31979205 through fd00f39f9: clean before d6ec28870, failing at every commit from d6ec28870 on.

Summary:
The non-ASCII character check in check-sources.sh used git grep -P (Perl regex), which requires git compiled with PCRE support. On systems without it, the command fails with exit code 128, which is != 1 (no match), so the check always reported a violation -- effectively dead.
Even in CI where git has PCRE2 support, the check was silently broken: git grep -P uses PCRE2 in UTF mode by default, which interprets [\x80-\xFF] as a Unicode codepoint range (U+0080 to U+00FF). Characters like em-dash (U+2014), arrows (U+2192), and math symbols (U+2248, etc.) fall outside that range and were not detected. Only Latin-1 Supplement characters (U+0080-U+00FF) would have been caught.
Replace with LC_ALL=C git grep using bash $'[\x80-\xff]' literal byte range, which works with basic regex in the C locale, and replace all non-ASCII characters in non-excluded source files:
- em-dash to --
- arrow to ->
- math symbols to ASCII equivalents (~=, <=, >=)
- box-drawing characters to ASCII art
Also exclude .github/ from the check, as scripts there can use non-ascii without disrupting RocksDB builds on non-UTF-8 systems.

Summary:
Add a circular ring buffer (InjectedErrorLog) to FaultInjectionTestFS that records the last 1000 injected errors. Each entry captures the timestamp, thread ID, FS API name with all arguments (file path, offset, buffer size, first 8 bytes of data in hex), and the injected error status. For example:
Append("/path/035354.sst", size=4096, head=[1a 2b 3c ...]) -> IOError (Retryable): injected write error
RenameFile("/path/tmp.sst", "/path/035355.sst") -> IOError: injected metadata write error
Read(offset=16384, size=4096) -> IOError (Retryable): injected read error
The ring buffer is printed to a file automatically:
- On any fatal signal (SIGABRT, SIGSEGV, SIGTERM, SIGINT, SIGHUP, SIGFPE, SIGBUS, SIGILL, SIGQUIT, SIGXCPU, SIGXFSZ, SIGSYS) via a registered crash callback
- At the end of db_stress main(), for diagnostic visibility even when the test completes normally
This addresses a key debugging gap: when write fault injection causes secondary failures (e.g., the builder error propagation issue in T257612259), the injected errors were previously completely silent with no logging trail. The ring buffer provides the missing diagnostic context to correlate fault injection with downstream failures.
Changes:
- port/stack_trace.h/.cc: Add RegisterCrashCallback() API; extend InstallStackTraceHandler() to catch all catchable termination signals
- utilities/fault_injection_fs.h: Add InjectedErrorLog class with printf-style Record(), HexHead() for data bytes, and signal-safe PrintAll()
- utilities/fault_injection_fs.cc: Record full API arguments and error status at all 31 fault injection call sites
- db_stress_tool/db_stress_tool.cc: Register crash callback and print ring buffer at end of main()

Summary:
It's been relatively easy to break our stack trace printer:
* If another thread reaches a signal condition such as a related SEGV or assertion failure while one is trying to print a stack trace from the signal handler, it seems to end the process abruptly without a stack trace.
* If the process exits normally in one thread (such as main finishing) while another is trying to print a stack trace from the signal handler, it seems the process will often end normally without a stack trace.
This change attempts to fix these issues, with
* Keep the custom signal handler installed as long as possible, so that other threads will most likely re-enter our custom handler. (We only switch back to default for triggering core dump or whatever after stack trace.)
* Use atomics and sleeps to implement a crude recursive mutex for ensuring all threads hitting the custom signal handler wait on the first that is trying to print a stack trace, while recursive signals in the same thread can still be handled cleanly.
* Use an atexit handler to hook into normal exit to (a) wait on a pending printing of stack trace when detectable and applicable, and (b) detect and warn when printing a stack trace might be interrupted by a process exit in progress. (I don't know how to pause that *after* our atexit handler has been called; the best I know how to do is warn, "In a race with process already exiting...".)

```

t.detach();
}
```
Followed by either `sleep(100)` or `usleep(100)` or usual process exit. And for recursive signal testing, inject `abort()` at various places in the handler.

Summary:
After https://github.com/facebook/rocksdb/issues/11905, I am preparing a DBImpl change to ensure all sufficiently recent sequence numbers since Open are covered by SeqnoToTimeMapping. **Intended follow-up**
However, there are a number of test changes I want to make prior to that to make it clear that I am not regressing the tests and production behavior at the same time.
* Start mock time in the tests well beyond epoch (time 0) so that we aren't normally reaching into pre-history for current time minus the preserve/preclude duration.
* Majorly clean up BasicSeqnoToTimeMapping to avoid confusing hard-coded bounds on GetProximalTimeBeforeSeqno() results.
* There is an unresolved/unexplained issue marked with FIXME that should be investigated when GetProximalTimeBeforeSeqno() is put into production.
* MultiCFs test was strangely generating 5 L0 files, four of which would be compacted into an L1, and then letting TTL compaction compact 1@L0+1@L1. Changing the starting time of the tests seemed to mess up the TTL compaction. But I suspect the TTL compaction was unintentional, so I've cut it down to just 4 L0 files, which compacts predictably.
* Unrelated: allow ROCKSDB_NO_STACK=1 to skip printing a stack trace on assertion failures.

Summary:
LIB_MODE=shared is much more efficient for building all the unit tests but comes with the downside of ugly stack traces, generally missing name demangling and source line info. Searching the internet suggests the reliable way to get stack traces with dynamic loading is with gdb.
This change automatically tries to use gdb to get a stack trace if built with LIB_MODE=shared, and only on Linux because that's where we have the capability to attach to the proper thread. (We could revise the exact conditions in the future.) If there's a failure invoking gdb, it falls back on the old method. Obscure details of making the output reasonable / pretty are in the source code comments.
Based on this, it was easy to make it so that running a test command with ROCKSDB_DEBUG=1 would invoke gdb whenever the stack trace handler was invoked, so I included that.
Intended follow-up: make LIB_MODE=shared the new default `make` build config
Pull Request resolved: https://github.com/facebook/rocksdb/pull/11150
Test Plan:
manual, mostly by injecting an "assert(false)" into a unit test and trying different build modes etc.
Although gdb is slower to start showing stack trace output, it seems overall faster in many if not most cases, presumably because it doesn't reload the symbol table for each stack entry. At least with parallel test runs, having many tests dumping stacks with the old method can take so long it appears to hang the test run.

Summary:
Instead of existing calls to ps from gnu_parallel, call a new wrapper that does ps, looks for unit test like processes, and uses pstack or gdb to print thread stack traces. Also, using `ps -wwf` instead of `ps -wf` ensures output is not cut off.
For security, CircleCI runs with security restrictions on ptrace (/proc/sys/kernel/yama/ptrace_scope = 1), and this change adds a work-around to `InstallStackTraceHandler()` (only used by testing tools) to allow any process from the same user to debug it. (I've also touched >100 files to ensure all the unit tests call this function.)

TSAN reports that our stack trace handler makes unsafe calls
during a signal handler. I just tried fixing some of them and I don't
think it's fixable unless we can get away from using FILE stdio. Even if
we can use lower level functions only, I'm not sure it's fixed.
I also tried suppressing the reports with function and file level TSAN
suppression, but that doesn't seem to work, perhaps because the
violation is reported on the callee, not the caller.
So I added a warning to be printed whenever these violations would be
reported that they are practically ignorable.

Summary: Sometimes, our tests fail because of normal `assert` call. It would be helpful to see stack trace in that case, too.
Test Plan: Added `assert(false)` and verified it prints out stack trace

Summary: While debugging Mac-only issue with ThreadLocalPtr, this was very useful. Let's print out stack trace in MAC OS, too.
Test Plan: Verified that somewhat useful stack trace was generated on mac. Will run PrintStack() on linux, too.

Summary:
This will help me a lot! When we hit an assertion in unittest, we get the whole stack trace now.
Also, changed stack trace a bit, we now include actual demangled C++ class::function symbols!
Test Plan: Added ASSERT_TRUE(false) to a test, observed a stack trace
