- Include the rest of the dependencies (kernel-headers, binutils, valgrind) in dependencies.sh
- updtade zst to 0.4.7
- It also fix a problem in clang scan build
Test Plan:
make check
USE_CLANG=1 make check
USE_CLANG=1 make analyze
coverage_test.sh
Update fbcode_config.sh to use latest versions automatically
Summary:
Update fbcode_config.sh so that It try to use the latest version for dependencies that we are using, after updating the code these libraries where updated
Another change is that we use the same tp2 directory as fbcode, so we dont need to keep changing commit hash every time we need to change a version of a compiler or a library
Test Plan:
make check -j64
USE_CLANG=1 make check -j64
DISABLE_JEMALLOC=1 OPT=-g make all valgrind_check -j32 (make sure it's running)

Fix transaction locking
Summary: Broke transaction locking in 4.4 in D52197. Will cherry-pick this change into 4.4 (which hasn't yet been fully released). Repro'd using db_bench.
Remove the SyncPoint usage in the destructor of PosixEnv
Summary:
Remove the SyncPoint usage in the destructor of PosixEnv as none
of any active tests is using it.
SyncPoint is a test-only utility class, and it's a static varible.
As a result, using SyncPoint in the destructor of PosixEnv will
make default Env depends on SyncPoint. Removing such dependency
could solve the problem crash issue only reproducable in Mac
environment.
Test Plan: OPT=-DTRAVIS V=1 make -j4 check on Mac environment
Summary:
When a child thread that uses ThreadLocalPtr, ThreadLocalPtr::OnThreadExit
will be called when that child thread is destroyed. However,
OnThreadExit will try to access a static singleton of ThreadLocalPtr,
which will be destroyed when the main thread exit. As a result,
when a child thread that uses ThreadLocalPtr exits AFTER the main thread
exits, illegal memory access will occur.
This diff includes a test that reproduce this legacy bug.

This patch fix this issue by having the thread local mutex never be deleted
(but will leak small piece of memory at the end.) The patch also describe
a better solution (thread_local) in the comment that requires gcc 4.8.1 and
in latest clang as a future work once we agree to move toward gcc 4.8.
