I propose that a QNX 6.5 port be introduced to PostgreSQL. I am new to PostgreSQL development, so please bear with me.
I have made good progress (with 1 outstanding issue, details below): * I created a QNX 6.5 port of PostgreSQL 9.3.4 which passes regression tests. * I merged my changes into 9.4beta2, and with a few minor changes, it passes regression tests. * QNX support states that QNX 6.5 SP1 binaries run on QNX 6.6 without modification, which I confirmed with a few quick tests. Summary of changes required for PostgreSQL 9.3.4 on QNX 6.5: * Typical changes required for any new port (template, configure.in, dynloader, etc.) * QNX lacks System V shared memory: I created "src/backend/port/posix_shmem.c" which replaces System V calls (shmget, shmat, shmdt, ...) with POSIX calls (shm_open, mmap, munmap, shm_unlink) * QNX lacks sigaction SA_RESTART: I modified "src/include/port.h" to define macros to retry system calls upon EINTR (open,read,write,...) when compiled on QNX * A few files required addition of #include <sys/select.h> on QNX (for fd_set). Additional changes required for PostgreSQL9.4beta2 on QNX 6.5: * "DSM" changes introduced in 9.4 (R. Haas) required that I make minor updates to my new "posix_shmem.c" code. * src\include\replication\logical.h: struct LogicalDecodingContext field "write" interferes with my "write" retry macro. Renaming field "write" to "do_write" solved this problem. Outstanding Issue #1: src/backend/commands/dbcommands.c :: createdb() complains when copying template1 to template0 (apparently a locale issue) "FATAL: 22023: new LC_CTYPE (C;collate:POSIX;ctype:POSIX) is incompatible with the LC_CTYPE of the template database (POSIX;messages:C)" I would appreciate help from an experienced PostgreSQL hacker to address this. I have temporarily disabled this check on QNX (I can live with the assumption/limitation that template0 and template1 contain strictly ASCII). I can work toward setting up a build farm member should this proposal be accepted. Your feedback and guidance on next steps is appreciated. Thank you. Keith Baker
