98a44559d5 Build for CYGWIN
Summary:
Make it build for CYGWIN.
Need to define "-std=gnu++11" instead of "-std=c++11" and use some replacement functions.

Test Plan: Build it and run some unit tests in CYGWIN

5fd33d26f1 Turn off -Wshadow
Summary:
So glibc is not -Wshadow-safe, so we need to turn it off :(

      error: ‘int sigaction(int, const sigaction*, sigaction*)’ hides
      constructor for ‘struct sigaction’

The rest of the changes in this diff is that we include .h files under rocksdb namespace, which is a no-no.

Test Plan: compiles now

a39e931e50 FlushProcess
Summary:
Abstract out FlushProcess and take it out of DBImpl.
This also includes taking DeletionState outside of DBImpl.

Currently this diff is only doing the refactoring. Future work includes:
1. Decoupling flush_process.cc, make it depend on less state
2. Write flush_process_test, which will mock out everything that FlushProcess depends on and test it in isolation

Test Plan: make check

46b3076c91 Better stack trace in MAC
Summary:
Now this gives us the real deal stack trace:

    Assertion failed: (false), function GetProperty, file db/db_impl.cc, line 4072.

fc3127e8de Install stack trace handlers in unit tests
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

f9f8965e96 Print out stack trace in mac, too
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.

9644e0e0c7 Print stack trace on assertion failure
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

Summary:
Change namespace from leveldb to rocksdb. This allows a single
application to link in open-source leveldb code as well as
rocksdb code into the same process.

06d3487b3f [RocksDB] Print stack trace to stderr instead of stdio.
Summary: Some scripts (like regression_build_test.sh) redirect stdio to a tmp file and delete it on exit. This would miss the stack trace output on segfault. Output to stderr would hopefully show us the stack trace in the continuous build output.

Test Plan: ./signal_test, make check

1255dcd446 [RocksDB] Add stacktrace signal handler
Summary:
This diff provides the ability to print out a stacktrace when the process receives certain signals.
Currently, we enable this for the following signals (program error related):
SIGILL SIGSEGV SIGBUS SIGABRT
Application simply #include "util/stack_trace.h" and call leveldb::InstallStackTraceHandler() during initialization, if signal handler is needed. It's not done automatically when openning db, because it's the application(process)'s responsibility to install signal handler and some applications might already have their own (like fbcode).

Sample output:
Received signal 11 (Segmentation fault)
#0  0x408ff0 ./signal_test() [0x408ff0] /home/haobo/rocksdb/util/signal_test.cc:4
#1  0x40827d ./signal_test() [0x40827d] /home/haobo/rocksdb/util/signal_test.cc:24
#2  0x7f8bb183172e /usr/local/fbcode/gcc-4.7.1-glibc-2.14.1/lib/libc.so.6(__libc_start_main+0x10e) [0x7f8bb183172e] ??:0
#3  0x408ebc ./signal_test() [0x408ebc] /home/engshare/third-party/src/glibc/glibc-2.14.1/glibc-2.14.1/csu/../sysdeps/x86_64/elf/start.S:113
Segmentation fault (core dumped)

For each frame, we print the raw pointer, the symbol provided by backtrace_symbols (still not good enough), and the source file/line. Note that address translation is done by directly shell out to addr2line. ??:0 means addr2line fails to do the translation. Hacky, but I think it's good for now.

Test Plan: signal_test.cc
