* Add bytea datatype to ECPG.Michael Meskes2019-02-18
| | | | | | | | | | | | So far ECPG programs had to treat binary data for bytea column as 'char' type. But this meant converting from/to escaped format with PQunescapeBytea/ PQescapeBytea() and therefore forcing users to add unnecessary code and cost for the conversion in runtime. By adding a dedicated datatype for bytea most of this special handling is no longer needed.

* Rename ecpg's various "extern.h" files to have distinct names.Tom Lane2018-12-01
| | | | | | | | | | | This should reduce confusion, and in particular make it safe to copy typename.c into preproc/ and compile it there. This doesn't affect anything outside ecpg, and particularly not end users, because these files don't get installed; they just exist to share declarations among the .c files of each subdirectory.

* Remove unnecessary parentheses in return statementsPeter Eisentraut2017-09-05
| | | | | | | | The parenthesized style has only been used in a few modules. Change that to use the style that is predominant across the whole tree. Reviewed-by: Michael Paquier <michael.paquier@gmail.com> Reviewed-by: Ryan Murphy <ryanfmurphy@gmail.com>
* Initial pgindent run with pg_bsd_indent version 2.0.Tom Lane2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new indent version includes numerous fixes thanks to Piotr Stefaniak. The main changes visible in this commit are: * Nicer formatting of function-pointer declarations. * No longer unexpectedly removes spaces in expressions using casts, sizeof, or offsetof. * No longer wants to add a space in "struct structname *varname", as well as some similar cases for const- or volatile-qualified pointers. * Declarations using PG_USED_FOR_ASSERTS_ONLY are formatted more nicely. * Fixes bug where comments following declarations were sometimes placed with no space separating them from the code. * Fixes some odd decisions for comments following case labels. * Fixes some cases where comments following code were indented to less than the expected column 33. On the less good side, it now tends to put more whitespace around typedef names that are not listed in typedefs.list. This might encourage us to put more effort into typedef name collection; it's not really a bug in indent itself. There are more changes coming after this round, having to do with comment indentation and alignment of lines appearing within parentheses. I wanted to limit the size of the diffs to something that could be reviewed without one's eyes completely glazing over, so it seemed better to split up the changes as much as practical.

* Use "%option prefix" to set API names in ecpg's lexer.Tom Lane2016-12-11
| | | | | | | | | | | | | | | | | Clean up some technical debt left behind by commit 72b1e3a21: instead of quickly hacking the name of base_yylex() with a #define, set it properly with "%option prefix". This causes the names of pgc.l's other exported symbols to change as well, so run around and modify the outside references to them as needed. Similarly, make pgc.l's external references to base_yylval use that variable's true name instead of a macro. The reason for doing this now is that the quick-hack solution will fail with future versions of flex, as reported by Дилян Палаузов. Hence, back-patch into 9.6 where the previous commit appeared, since it's likely people will build 9.6 with newer flex versions during its lifetime.

* Various Coverity-spotted fixesStephen Frost2014-03-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | A number of issues were identified by the Coverity scanner and are addressed in this patch. None of these appear to be security issues and many are mostly cosmetic changes. Short comments for each of the changes follows. Correct the semi-colon placement in be-secure.c regarding SSL retries. Remove a useless comparison-to-NULL in proc.c (value is dereferenced prior to this check and therefore can't be NULL). Add checking of chmod() return values to initdb. Fix a couple minor memory leaks in initdb. Fix memory leak in pg_ctl- involves free'ing the config file contents. Use an int to capture fgetc() return instead of an enum in pg_dump. Fix minor memory leaks in pg_dump. (note minor change to convertOperatorReference()'s API) Check fclose()/remove() return codes in psql. Check fstat(), find_my_exec() return codes in psql. Various ECPG memory leak fixes. Check find_my_exec() return in ECPG. Explicitly ignore pqFlush return in libpq error-path. Change PQfnumber() to avoid doing an strdup() when no changes required. Remove a few useless check-against-NULL's (value deref'd beforehand). Check rmtree(), malloc() results in pg_regress. Also check get_alternative_expectfile() return in pg_regress.

* Create real array comparison functions (that use the element datatype'sTom Lane2003-06-27
| | | | | | | | | | | | | | | | comparison functions), replacing the highly bogus bitwise array_eq. Create a btree index opclass for ANYARRAY --- it is now possible to create indexes on array columns. Arrange to cache the results of catalog lookups across multiple array operations, instead of repeating the lookups on every call. Add string_to_array and array_to_string functions. Remove singleton_array, array_accum, array_assign, and array_subscript functions, since these were for proof-of-concept and not intended to become supported functions. Minor adjustments to behavior in some corner cases with empty or zero-dimensional arrays. Joe Conway (with some editorializing by Tom Lane).
