      fix leak in error handling of debug populate command (#7062) · c69a9b2f
      Wen Hui authored
      valsize was not modified during the for loop below instead of getting from c->argv[4], therefore there is no need to put inside the for loop.. Moreover, putting the check outside loop will also avoid memory leaking, decrRefCount(key) should be called in the original code if we put the check in for loop

      Add registers dump support for Apple silicon (#7453) · c2b5f1c1
      Developer-Ecosystem-Engineering authored
      Export following environment variables before building on macOS on Apple silicon
      
      export ARCH_FLAGS="-arch arm64"
      export SDK_NAME=macosx
      export SDK_PATH=$(xcrun --show-sdk-path --sdk $SDK_NAME)
      export CFLAGS="$ARCH_FLAGS -isysroot $SDK_PATH -I$SDK_PATH/usr/include"
      export CXXFLAGS=$CFLAGS
      export LDFLAGS="$ARCH_FLAGS"
      export CC="$(xcrun -sdk $SDK_PATH --find clang) $CFLAGS"
      export CXX="$(xcrun -sdk $SDK_PATH --find clang++) $CXXFLAGS"
      export LD="$(xcrun -sdk $SDK_PATH --find ld) $LDFLAGS"
      
      make
      make test
      ..
      All tests passed without errors!

      tests/valgrind: don't use debug restart (#7404) · 69ade873
      Oran Agra authored
      * tests/valgrind: don't use debug restart
      
      DEBUG REATART causes two issues:
      1. it uses execve which replaces the original process and valgrind doesn't
         have a chance to check for errors, so leaks go unreported.
      2. valgrind report invalid calls to close() which we're unable to resolve.
      
      So now the tests use restart_server mechanism in the tests, that terminates
      the old server and starts a new one, new PID, but same stdout, stderr.
      
      since the stderr can contain two or more valgrind report, it is not enough
      to just check for the absence of leaks, we also need to check for some known
      errors, we do both, and fail if we either find an error, or can't find a
      report saying there are no leaks.
      
      other changes:
      - when killing a server that was already terminated we check for leaks too.
      - adding DEBUG LEAK which was used to test it.
      - adding --trace-children to valgrind, although no longer needed.
      - since the stdout contains two or more runs, we need slightly different way
        of checking if the new process is up (explicitly looking for the new PID)
      - move the code that handles --wait-server to happen earlier (before
        watching the startup message in the log), and serve the restarted server too.

      add daily github actions with libc malloc and valgrind · deee2c1e
      Oran Agra authored
      * fix memlry leaks with diskless replica short read.
      * fix a few timing issues with valgrind runs
      * fix issue with valgrind and watchdog schedule signal
      
      about the valgrind WD issue:
      the stack trace test in logging.tcl, has issues with valgrind:
      ==28808== Can't extend stack to 0x1ffeffdb38 during signal delivery for thread 1:
      ==28808==   too small or bad protection modes
      
      it seems to be some valgrind bug with SA_ONSTACK.
      SA_ONSTACK seems unneeded since WD is not recursive (SA_NODEFER was removed),
      also, not sure if it's even valid without a call to sigaltstack()

      Modules hooks: complete missing hooks for the initial set of hooks · 51c3ff8d
      Oran Agra authored
      * replication hooks: role change, master link status, replica online/offline
      * persistence hooks: saving, loading, loading progress
      * misc hooks: cron loop, shutdown, module loaded/unloaded
      * change the way hooks test work, and add tests for all of the above
      
      startLoading() now gets flag indicating what is loaded.
      stopLoading() now gets an indication of success or failure.
      adding startSaving() and stopSaving() with similar args and role.

      make redis purge jemalloc after flush, and enable background purging thread · 09f99c2a
      Oran Agra authored
      jemalloc 5 doesn't immediately release memory back to the OS, instead there's a decaying
      mechanism, which doesn't work when there's no traffic (no allocations).
      this is most evident if there's no traffic after flushdb, the RSS will remain high.
      
      1) enable jemalloc background purging
      2) explicitly purge in flushdb

      Don't assume the __x86_64__ pointer size to avoid warnings on x32. · d0089cf2
      Chris Lamb authored
      __x86_64__ is defined on the on the x32 architecture and the conditionals in
      debug.c therefore assume the size of (void*) etc:
      
        debug.c: In function 'getMcontextEip':
        debug.c:757:12: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
             return (void*) uc->uc_mcontext.gregs[16]; /* Linux 64 */
                    ^
        debug.c: In function 'logRegisters':
        debug.c:920:21: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
             logStackContent((void**)uc->uc_mcontext.gregs[15]);
      
      We can remedy this by checking for __ILP32__ first. See:
      
        https://wiki.debian.org/ArchitectureSpecificsMemo
      
      ... for more info.
