# Makefile
Build src/port files as a library with -fPIC, and use that in libpq. libpq and ecpg need shared-library-friendly versions of assorted src/port/ and src/common/ modules. Up to now, they got those by symlinking the individual source files and compiling them locally. That's baroque, and a pain to maintain, and it results in some amount of duplicated compile work. It might've made sense when only a couple of files were needed, but the list has grown and grown and grown :-( It makes more sense to have the originating directory build a third variant of libpgport.a/libpgcommon.a containing modules built with $(CFLAGS_SL), and just link that into the shared library. Unused files won't get linked, so the end result should be the same. This patch makes a down payment on that idea by having src/port/ build such a library and making libpq use it. If the buildfarm doesn't expose fatal problems with the approach, I'll extend it to the other cases. Discussion: https://postgr.es/m/13022.1538003440@sss.pgh.pa.us

Move a couple of initdb's subroutines into src/port/. mkdir_p and check_data_dir will be useful in CREATE TABLESPACE, since we have agreed that that command should handle subdirectory creation just like initdb creates the PGDATA directory. Push them into src/port/ so that they are available to both initdb and the backend. Rename to pg_mkdir_p and pg_check_dir, just to be on the safe side. Add FreeBSD's copyright notice to pgmkdirp.c, since that's where the code came from originally (this really should have been in initdb.c). Very marginal code/comment cleanup.

# LIBOBJS is set by configure (via Makefile.global) to be the list of object
# files that are conditionally needed as determined by configure's probing.
Change initdb and CREATE DATABASE to actively reject attempts to create databases with encodings that are incompatible with the server's LC_CTYPE locale, when we can determine that (which we can on most modern platforms, I believe). C/POSIX locale is compatible with all encodings, of course, so there is still some usefulness to CREATE DATABASE's ENCODING option, but this will insulate us against all sorts of recurring complaints caused by mismatched settings. I moved initdb's existing LC_CTYPE-to-encoding mapping knowledge into a new src/port/ file so it could be shared by CREATE DATABASE.

Remove arbitrary restrictions on password length. This patch started out with the goal of harmonizing various arbitrary limits on password length, but after awhile a better idea emerged: let's just get rid of those fixed limits. recv_password_packet() has an arbitrary limit on the packet size, which we don't really need, so just drop it. (Note that this doesn't really affect anything for MD5 or SCRAM password verification, since those will hash the user's password to something shorter anyway. It does matter for auth methods that require a cleartext password.) Likewise remove the arbitrary error condition in pg_saslprep(). The remaining limits are mostly in client-side code that prompts for passwords. To improve those, refactor simple_prompt() so that it allocates its own result buffer that can be made as big as necessary. Actually, it proves best to make a separate routine pg_get_line() that has essentially the semantics of fgets(), except that it allocates a suitable result buffer and hence will never return a truncated line. (pg_get_line has a lot of potential applications to replace randomly-sized fgets buffers elsewhere, but I'll leave that for another patch.) I built pg_get_line() atop stringinfo.c, which requires moving that code to src/common/; but that seems fine since it was a poor fit for src/port/ anyway. This patch is mostly mine, but it owes a good deal to Nathan Bossart who pressed for a solution to the password length problem and created a predecessor patch. Also thanks to Peter Eisentraut and Stephen Frost for ideas and discussion. Discussion: https://postgr.es/m/09512C4F-8CB9-4021-B455-EF4C4F0D55A0@amazon.com

Split all OBJS style lines in makefiles into one-line-per-entry style. When maintaining or merging patches, one of the most common sources for conflicts are the list of objects in makefiles. Especially when the split across lines has been changed on both sides, which is somewhat common due to attempting to stay below 80 columns, those conflicts are unnecessarily laborious to resolve. By splitting, and alphabetically sorting, OBJS style lines into one object per line, conflicts should be less frequent, and easier to resolve when they still occur.

Rename port/thread.c to port/user.c. Historically this module dealt with thread-safety of system interfaces, but now all that's left is wrapper code for user name and home directory lookup. Arguably the Windows variants of this logic could be moved in here too, to justify its presence under port. For now, just tidy up some obsolete references to multi-threading, and give the file a meaningful name.

Unlink static libraries before rebuilding them. When the library already exists in the build directory, "ar" preserves members not named on its command line. This mattered when, for example, a "configure" rerun dropped a file from $(LIBOBJS). libpgport carried the obsolete member until "make clean". Back-patch to 9.0 (all supported versions).

autoconf: Unify CFLAGS_SSE42 and CFLAGS_ARMV8_CRC32C Until now we emitted the cflags to build the CRC objects into architecture specific variables. That doesn't make a whole lot of sense to me - we're never going to target x86 and arm at the same time, so they don't need to be separate variables. It might be better to instead continue to have CFLAGS_SSE42 / CFLAGS_ARMV8_CRC32C be computed by PGAC_ARMV8_CRC32C_INTRINSICS / PGAC_SSE42_CRC32_INTRINSICS and then set CFLAGS_CRC based on those. But it seems unlikely that we'd need other sets of CRC specific flags for those two architectures at the same time. This simplifies the upcoming meson PGXS compatibility.

Use ARMv8 CRC instructions where available. ARMv8 introduced special CPU instructions for calculating CRC-32C. Use them, when available, for speed. Like with the similar Intel CRC instructions, several factors affect whether the instructions can be used. The compiler intrinsics for them must be supported by the compiler, and the instructions must be supported by the target architecture. If the compilation target architecture does not support the instructions, but adding "-march=armv8-a+crc" makes them available, then we compile the code with a runtime check to determine if the host we're running on supports them or not. For the runtime check, use glibc getauxval() function. Unfortunately, that's not very portable, but I couldn't find any more portable way to do it. If getauxval() is not available, the CRC instructions will still be used if the target architecture supports them without any additional compiler flags, but the runtime check will not be available.

Build src/port files as a library with -fPIC, and use that in libpq. libpq and ecpg need shared-library-friendly versions of assorted src/port/ and src/common/ modules. Up to now, they got those by symlinking the individual source files and compiling them locally. That's baroque, and a pain to maintain, and it results in some amount of duplicated compile work. It might've made sense when only a couple of files were needed, but the list has grown and grown and grown :-( It makes more sense to have the originating directory build a third variant of libpgport.a/libpgcommon.a containing modules built with $(CFLAGS_SL), and just link that into the shared library. Unused files won't get linked, so the end result should be the same. This patch makes a down payment on that idea by having src/port/ build such a library and making libpq use it. If the buildfarm doesn't expose fatal problems with the approach, I'll extend it to the other cases. Discussion: https://postgr.es/m/13022.1538003440@sss.pgh.pa.us

Change initdb and CREATE DATABASE to actively reject attempts to create databases with encodings that are incompatible with the server's LC_CTYPE locale, when we can determine that (which we can on most modern platforms, I believe). C/POSIX locale is compatible with all encodings, of course, so there is still some usefulness to CREATE DATABASE's ENCODING option, but this will insulate us against all sorts of recurring complaints caused by mismatched settings. I moved initdb's existing LC_CTYPE-to-encoding mapping knowledge into a new src/port/ file so it could be shared by CREATE DATABASE.

libpgport_srv.a: $(OBJS_SRV)
Unlink static libraries before rebuilding them. When the library already exists in the build directory, "ar" preserves members not named on its command line. This mattered when, for example, a "configure" rerun dropped a file from $(LIBOBJS). libpgport carried the obsolete member until "make clean". Back-patch to 9.0 (all supported versions).

Fix dependency tracking for src/port/%_srv.o files Because they use their own compilation rule, they don't use the dependency tracking logic from Makefile.global.
