* Fix ancient bug in ecpg's pthread_once() emulation for Windows.Tom Lane2020-10-24
| | | | | | | | | | | | | | | | We must not set the "done" flag until after we've executed the initialization function. Otherwise, other threads can fall through the initial unlocked test before initialization is really complete. This has been seen to cause rare failures of ecpg's thread/descriptor test, and it could presumably cause other sorts of misbehavior in threaded ECPG-using applications, since ecpglib relies on pthread_once() in several places. Diagnosis and patch by me, based on investigation by Alexander Lakhin. Back-patch to all supported branches (the bug dates to 2007).

* Increase hard-wired timeout values in ecpg regression tests.Tom Lane2020-08-04
| | | | | | | | | | | | | | A couple of test cases had connect_timeout=14, a value that seems to have been plucked from a hat. While it's more than sufficient for normal cases, slow/overloaded buildfarm machines can get a timeout failure here, as per recent report from "sungazer". Increase to 180 seconds, which is in line with our typical timeouts elsewhere in the regression tests. Back-patch to 9.6; the code looks different in 9.5, and this doesn't seem to be quite worth the effort to adapt to that.

* Fix handling of structure for bytea data type in ECPGMichael Paquier2020-07-27
| | | | | | | | | | | | | | Some code paths dedicated to bytea used the structure for varchar. This did not lead to any actual bugs, as bytea and varchar have the same definition, but it could become a trap if one of these definitions changes for a new feature or a bug fix. Issue introduced by 050710b.

* Fix out-of-memory handling in ecpglib.Tom Lane2020-01-19
| | | | | | | | | | ecpg_build_params() would crash on a null pointer dereference if realloc() failed, due to updating the persistent "stmt" struct too aggressively. (Even without the crash, this would've leaked the old storage that we were trying to realloc.) Per Coverity. This seems to have been broken in commit 0cc050794, so back-patch into v12.
* Fix off-by-one error in PGTYPEStimestamp_fmt_ascTomas Vondra2019-11-30
| | | | | | | | | | | | | | | When using %b or %B patterns to format a date, the code was simply using tm_mon as an index into array of month names. But that is wrong, because tm_mon is 1-based, while array indexes are 0-based. The result is we either use name of the next month, or a segfault (for December). Fix by subtracting 1 from tm_mon for both patterns, and add a regression test triggering the issue. Backpatch to all supported versions (the bug is there far longer, since at least 2003).

* Move declaration of ecpg_gettext() to a saner place.Tom Lane2019-11-07
| | | | | | | | | | | | | | | | | | | | | Declaring this in the client-visible header ecpglib.h was a pretty poor decision. It's not meant to be application-callable (and if it was, putting it outside the extern "C" { ... } wrapper means that C++ clients would fail to call it). And the declaration would not even compile for a client, anyway, since it would not have the macro pg_attribute_format_arg(). Fortunately, it seems that no clients have tried to include this header with ENABLE_NLS defined, or we'd have gotten complaints about that. But we have no business putting such a restriction on client code. Move the declaration to ecpglib_extern.h, since in fact nothing outside src/interfaces/ecpg/ecpglib/ needs to call it. The practical effect of this is just that clients can now safely #include ecpglib.h while having ENABLE_NLS defined, but that seems like enough of a reason to back-patch it.

* Get rid of useless/dangerous redefinition of bool in ECPG.Tom Lane2019-10-25
| | | | | | | | | | | | | | | | | | | | | | | | | pgtypeslib_extern.h contained fallback definitions of "bool", "FALSE", and "TRUE". The latter two are just plain unused, and have been for awhile. The former came into play only if there wasn't a macro definition of "bool", which is true only if we aren't using <stdbool.h>. However, it then defined bool as "char"; since commit d26a810eb that conflicts with c.h's desire to use "unsigned char". We'd missed seeing any bad effects of that due to accidental header inclusion order choices, but dddf4cdc3 exposed that it was problematic. To fix, let's just get rid of these definitions. They should not be needed because everyplace in Postgres should be relying on c.h to provide a definition for type bool. (Note that despite its name, pgtypeslib_extern.h isn't exposed to any outside code; we don't install it.) This doesn't fully resolve the issue, because ecpglib.h is doing similar things, but that seems to require more thought to fix. Back-patch to v12 where d26a810eb came in, to forestall any unpleasant surprises from future back-patched bug fixes.

* Un-break ecpg tests for Windows.Tom Lane2019-06-02
| | | | | | | | | | Declaring a function "inline" still doesn't work with Windows compilers (C99? what's that?), unless the macro provided by pg_config.h is in-scope, which it is not in our ECPG test programs. So the workaround I tried to use in commit 7640f9312 doesn't work for Windows. Revert the change in printf_hack.h, and instead just blacklist that file in cpluspluscheck --- since it's a not-installed test file, we don't really need to verify its C++ cleanliness anyway.

* Fix assorted header files that failed to compile standalone.Tom Lane2019-05-31
| | | | | | | | | | | | | | | | | | | We have a longstanding project convention that all .h files should be includable with no prerequisites other than postgres.h. This is tested/relied-on by cpluspluscheck. However, cpluspluscheck has not historically been applied to most headers outside the src/include tree, with the predictable consequence that some of them don't work. Fix that, usually by adding missing #include dependencies. The change in printf_hack.h might require some explanation: without it, my C++ compiler whines that the function is unused. There's not so many call sites that "inline" is going to cost much, and besides all the callers are in test code that we really don't care about the size of. There's no actual bugs being fixed here, so I see no need to back-patch. Discussion: https://postgr.es/m/b517ec3918d645eb950505eac8dd434e@gaz-is.ru

* Move logging.h and logging.c from src/fe_utils/ to src/common/.Tom Lane2019-05-14
| | | | | | | | | | | | | | | | | | | | | | | | The original placement of this module in src/fe_utils/ is ill-considered, because several src/common/ modules have dependencies on it, meaning that libpgcommon and libpgfeutils now have mutual dependencies. That makes it pointless to have distinct libraries at all. The intended design is that libpgcommon is lower-level than libpgfeutils, so only dependencies from the latter to the former are acceptable. We already have the precedent that fe_memutils and a couple of other modules in src/common/ are frontend-only, so it's not stretching anything out of whack to treat logging.c as a frontend-only module in src/common/. To the extent that such modules help provide a common frontend/backend environment for the rest of common/ to use, it's a reasonable design. (logging.c does not yet provide an ereport() emulation, but one can dream.) Hence, move these files over, and revert basically all of the build-system changes made by commit cc8d41511. There are no places that need to grow new dependencies on libpgcommon, further reinforcing the idea that this is the right solution.

* Unified logging system for command-line programsPeter Eisentraut2019-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This unifies the various ad hoc logging (message printing, error printing) systems used throughout the command-line programs. Features: - Program name is automatically prefixed. - Message string does not end with newline. This removes a common source of inconsistencies and omissions. - Additionally, a final newline is automatically stripped, simplifying use of PQerrorMessage() etc., another common source of mistakes. - I converted error message strings to use %m where possible. - As a result of the above several points, more translatable message strings can be shared between different components and between frontends and backend, without gratuitous punctuation or whitespace differences. - There is support for setting a "log level". This is not meant to be user-facing, but can be used internally to implement debug or verbose modes. - Lazy argument evaluation, so no significant overhead if logging at some level is disabled. - Some color in the messages, similar to gcc and clang. Set PG_COLOR=auto to try it out. Some colors are predefined, but can be customized by setting PG_COLORS. - Common files (common/, fe_utils/, etc.) can handle logging much more simply by just using one API without worrying too much about the context of the calling program, requiring callbacks, or having to pass "progname" around everywhere. - Some programs called setvbuf() to make sure that stderr is unbuffered, even on Windows. But not all programs did that. This is now done centrally. Soft goals: - Reduces vertical space use and visual complexity of error reporting in the source code. - Encourages more deliberate classification of messages. For example, in some cases it wasn't clear without analyzing the surrounding code whether a message was meant as an error or just an info. - Concepts and terms are vaguely aligned with popular logging frameworks such as log4j and Python logging. This is all just about printing stuff out. Nothing affects program flow (e.g., fatal exits). The uses are just too varied to do that. Some existing code had wrappers that do some kind of print-and-exit, and I adapted those. I tried to keep the output mostly the same, but there is a lot of historical baggage to unwind and special cases to consider, and I might not always have succeeded. One significant change is that pg_rewind used to write all error messages to stdout. That is now changed to stderr.

* Fix ecpg bugs caused by missing semicolons in the backend grammar.Tom Lane2019-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | The Bison documentation clearly states that a semicolon is required after every grammar rule, and our scripts that generate ecpg's grammar from the backend's implicitly assumed this is true. But it turns out that only ancient versions of Bison actually enforce that. There have been a couple of rules without trailing semicolons in gram.y for some time, and as a consequence, ecpg's grammar was faulty and produced wrong output for the affected statements. To fix, add the missing semis, and add some cross-checks to ecpg's scripts so that they'll bleat if we mess this up again. The cases that were broken were: * "SET variable = DEFAULT" (but not "SET variable TO DEFAULT"), as well as allied syntaxes such as ALTER SYSTEM SET ... DEFAULT. These produced syntactically invalid output that the server would reject. * Multiple type names in DROP TYPE/DOMAIN commands. Only the first type name would be listed in the emitted command.
