2020-12-10Refactor MD5 implementations according to new cryptohash infrastructureMichael Paquier
This commit heavily reorganizes the MD5 implementations that exist in the tree in various aspects. First, MD5 is added to the list of options available in cryptohash.c and cryptohash_openssl.c. This means that if building with OpenSSL, EVP is used for MD5 instead of the fallback implementation that Postgres had for ages. With the recent refactoring work for cryptohash functions, this change is straight-forward. If not building with OpenSSL, a fallback implementation internal to src/common/ is used. Second, this reduces the number of MD5 implementations present in the tree from two to one, by moving the KAME implementation from pgcrypto to src/common/, and by removing the implementation that existed in src/common/. KAME was already structured with an init/update/final set of routines by pgcrypto (see original pgcrypto/md5.h) for compatibility with OpenSSL, so moving it to src/common/ has proved to be a straight-forward move, requiring no actual manipulation of the internals of each routine. Some benchmarking has not shown any performance gap between both implementations. Similarly to the fallback implementation used for SHA2, the fallback implementation of MD5 is moved to src/common/md5.c with an internal header called md5_int.h for the init, update and final routines. This gets then consumed by cryptohash.c. The original routines used for MD5-hashed passwords are moved to a separate file called md5_common.c, also in src/common/, aimed at being shared between all MD5 implementations as utility routines to keep compatibility with any code relying on them. Like the SHA2 changes, this commit had its round of tests on both Linux and Windows, across all versions of OpenSSL supported on HEAD, with and even without OpenSSL.

2017-06-21Phase 2 of pgindent updates.Tom Lane
Change pg_bsd_indent to follow upstream rules for placement of comments to the right of code, and remove pgindent hack that caused comments following #endif to not obey the general rule. Commit e3860ffa4dd0dad0dd9eea4be9cc1412373a8c89 wasn't actually using the published version of pg_bsd_indent, but a hacked-up version that tried to minimize the amount of movement of comments to the right of code. The situation of interest is where such a comment has to be moved to the right of its default placement at column 33 because there's code there. BSD indent has always moved right in units of tab stops in such cases --- but in the previous incarnation, indent was working in 8-space tab stops, while now it knows we use 4-space tabs. So the net result is that in about half the cases, such comments are placed one tab stop left of before. This is better all around: it leaves more room on the line for comment text, and it means that in such cases the comment uniformly starts at the next 4-space tab stop after the code, rather than sometimes one and sometimes two tabs after. Also, ensure that comments following #endif are indented the same as comments following other preprocessor commands such as #else. That inconsistency turns out to have been self-inflicted damage from a poorly-thought-through post-indent "fixup" in pgindent. This patch is much less interesting than the first round of indent changes, but also bulkier, so I thought it best to separate the effects.

2014-05-06pgindent run for 9.4Bruce Momjian
This includes removing tabs after periods in C comments, which was applied to back branches, so this change should not effect backpatching.

2001-01-09The KAME files md5.* and sha1.* have the following changelogBruce Momjian
entry: ---------------------------- revision 1.2 date: 2000/12/04 01:20:38; author: tgl; state: Exp; lines: +18 -18 Eliminate some of the more blatant platform-dependencies ... it builds here now, anyway ... ---------------------------- Which basically changes u_int*_t -> uint*_t, so now it does not compile neither under Debian 2.2 nor under NetBSD 1.5 which is platform independent<B8> all right. Also it replaces $KAME$ with $Id$ which is Bad Thing. PostgreSQL Id should be added as a separate line so the file history could be seen. So here is patch: * changes uint*_t -> uint*. I guess that was the original intention * adds uint64 type to include/c.h because its needed [somebody should check if I did it right] * adds back KAME Id, because KAME is the master repository * removes stupid c++ comments in pgcrypto.c * removes <sys/types.h> from the code, its not needed -- marko Marko Kreen
