Use the new shmem allocation functions in a few core subsystems These subsystems have some complicating properties, making them slightly harder to convert than most:
- The initialization callbacks of some of these subsystems have dependencies, i.e. they need to be initialized in the right order. - The ProcGlobal pointer still needs to be inherited by the BackendParameters mechanism on EXEC_BACKEND builds, because ProcGlobal is required by InitProcess() to get a PGPROC entry, and the PGPROC entry is required to use LWLocks, and usually attaching to shared memory areas requires the use of LWLocks. - Similarly, ProcSignal pointer still needs to be handled by BackendParameters, because query cancellation connections access it without calling InitProcess Reviewed-by: Ashutosh Bapat <[email protected]> Reviewed-by: Matthias van de Meent <[email protected]> Reviewed-by: Daniel Gustafsson <[email protected]> Discussion: https://www.postgresql.org/message-id/CAExHW5vM1bneLYfg0wGeAa=52uij3z4vkd3aj72x8fw6k3k...@mail.gmail.com Branch ------ master Details ------- https://git.postgresql.org/pg/commitdiff/c6d55714ba4c282dcf5fb5fe5ef2a5cad0b06e81 Modified Files -------------- src/backend/access/transam/twophase.c | 2 +- src/backend/access/transam/varsup.c | 35 +++--- src/backend/port/posix_sema.c | 22 ++-- src/backend/port/sysv_sema.c | 21 ++-- src/backend/port/win32_sema.c | 11 +- src/backend/storage/ipc/dsm.c | 64 ++++++----- src/backend/storage/ipc/dsm_registry.c | 36 ++++--- src/backend/storage/ipc/ipci.c | 28 ----- src/backend/storage/ipc/latch.c | 8 +- src/backend/storage/ipc/pmsignal.c | 51 +++++---- src/backend/storage/ipc/procarray.c | 110 +++++++++---------- src/backend/storage/ipc/procsignal.c | 64 ++++++----- src/backend/storage/ipc/sinvaladt.c | 38 +++---- src/backend/storage/lmgr/proc.c | 191 +++++++++++++++++---------------- src/backend/utils/hash/dynahash.c | 3 +- src/include/access/transam.h | 2 - src/include/storage/dsm.h | 3 - src/include/storage/dsm_registry.h | 2 - src/include/storage/pg_sema.h | 6 +- src/include/storage/pmsignal.h | 2 - src/include/storage/proc.h | 2 - src/include/storage/procarray.h | 2 - src/include/storage/procsignal.h | 3 - src/include/storage/sinvaladt.h | 2 - src/include/storage/subsystemlist.h | 17 ++- 25 files changed, 344 insertions(+), 381 deletions(-)
