* Add some const qualifiersPeter Eisentraut2023-09-26
| | | | | | | | | | | There was a mismatch between the const qualifiers for excludeDirContents in src/backend/backup/basebackup.c and src/bin/pg_rewind/filemap.c, which led to a quick search for similar cases. We should make excludeDirContents match, but the rest of the changes seem like a good idea as well.

* libpq error message refactoringPeter Eisentraut2022-11-15
| | | | | | | | | | | | | | | | | | | libpq now contains a mix of error message strings that end with newlines and don't end with newlines, due to some newer code paths with new ways of passing errors around. This leads to confusion and mistakes both during development and translation. This adds new functions libpq_append_error() and libpq_append_conn_error() that encapsulate common code paths for producing error message strings. Notably, these functions append the newline, so that the string appearing in the code does not end with a newline. This makes (almost) all error message strings in libpq uniform in this regard (and also consistent with how we handle it outside of libpq code). (There are a few exceptions that are difficult to fit into this scheme, but they are only a few.)

* Implement %m in src/port/snprintf.c, and teach elog.c to rely on that.Tom Lane2018-09-26
| | | | | | | | | | | | | | | | | | | | | | | I started out with the idea that we needed to detect use of %m format specs in contexts other than elog/ereport calls, because we couldn't rely on that working in *printf calls. But a better answer is to fix things so that it does work. Now that we're using snprintf.c all the time, we can implement %m in that and we've fixed the problem. This requires also adjusting our various printf-wrapping functions so that they ensure "errno" is preserved when they call snprintf.c. Remove elog.c's handmade implementation of %m, and let it rely on snprintf to support the feature. That should provide some performance gain, though I've not attempted to measure it. There are a lot of places where we could now simplify 'printf("%s", strerror(errno))' into 'printf("%m")', but I'm not in any big hurry to make that happen.

* Require a C99-compliant snprintf(), and remove related workarounds.Tom Lane2018-08-16
| | | | | | | | | | | | | | | | | | | | | | | | Since our substitute snprintf now returns a C99-compliant result, there's no need anymore to have complicated code to cope with pre-C99 behavior. We can just make configure substitute snprintf.c if it finds that the system snprintf() is pre-C99. (Note: I do not believe that there are any platforms where this test will trigger that weren't already being rejected due to our other C99-ish feature requirements for snprintf. But let's add the check for paranoia's sake.) Then, simplify the call sites that had logic to cope with the pre-C99 definition. I also dropped some stuff that was being paranoid about the possibility of snprintf overrunning the given buffer. The only reports we've ever heard of that being a problem were for Solaris 7, which is long dead, and we've sure not heard any reports of these assertions triggering in a long time. So let's drop that complexity too. Likewise, drop some code that wasn't trusting snprintf to set errno when it returns -1. That would be not-per-spec, and again there's no real reason to believe it is a live issue, especially not for snprintfs that pass all of configure's feature checks.

* Phase 2 of pgindent updates.Tom Lane2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Tweak __attribute__-wrapping macros for better pgindent results.Tom Lane2015-03-26
| | | | | | | | | | | | | | | | | | | | | This improves on commit bbfd7edae5aa5ad5553d3c7e102f2e450d4380d4 by making two simple changes: * pg_attribute_noreturn now takes parentheses, ie pg_attribute_noreturn(). Likewise pg_attribute_unused(), pg_attribute_packed(). This reduces pgindent's tendency to misformat declarations involving them. * attributes are now always attached to function declarations, not definitions. Previously some places were taking creative shortcuts, which were not merely candidates for bad misformatting by pgindent but often were outright wrong anyway. (It does little good to put a noreturn annotation where callers can't see it.) In any case, if we would like to believe that these macros can be used with non-gcc compilers, we should avoid gratuitous variance in usage patterns. I also went through and manually improved the formatting of a lot of declarations, and got rid of excessively repetitive (and now obsolete anyway) comments informing the reader what pg_attribute_printf is for.
* Add macros wrapping all usage of gcc's __attribute__.Andres Freund2015-03-11
| | | | | | | | | | | | | | | | | | | | Until now __attribute__() was defined to be empty for all compilers but gcc. That's problematic because it prevents using it in other compilers; which is necessary e.g. for atomics portability. It's also just generally dubious to do so in a header as widely included as c.h. Instead add pg_attribute_format_arg, pg_attribute_printf, pg_attribute_noreturn macros which are implemented in the compilers that understand them. Also add pg_attribute_noreturn and pg_attribute_packed, but don't provide fallbacks, since they can affect functionality. This means that external code that, possibly unwittingly, relied on __attribute__ defined to be empty on !gcc compilers may now run into warnings or errors on those compilers. But there shouldn't be many occurances of that and it's hard to work around... Discussion: 54B58BA3.8040302@ohmu.fi Author: Oskari Saarenmaa, with some minor changes by me.

* Improve pqexpbuffer.c to use modern vsnprintf implementations efficiently.Tom Lane2013-10-25
| | | | | | | | | | | | | When using a C99-compliant vsnprintf, we can use its report of the required buffer size to avoid making multiple loops through the formatting logic. This is similar to the changes recently made in stringinfo.c, but we can't use psprintf.c here because in libpq we don't want to exit() on error. (The behavior pqexpbuffer.c has historically used is to mark the PQExpBuffer as "broken", ie empty, if it runs into any fatal problem.) To avoid duplicating code more than necessary, I refactored printfPQExpBuffer and appendPQExpBuffer to share a subroutine that's very similar to psprintf.c's pvsnprintf in spirit.

The previous coding would just silently discard portions of the intended buffer contents, as exhibited in trouble report from Sam Mason. Also, tweak psql's main loop to correctly detect and report such overruns. There's probably much more that should be done in this line, but this is a start.
