2018-12-01Rename ecpg's various "extern.h" files to have distinct names.Tom Lane
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.

2018-11-13Remove unused code in ECPG.Tom Lane
scanner_init/scanner_finish weren't actually called from anywhere, and the scanbuf variables they set up weren't used either. Remove unused declaration for mm_realloc, too. John Naylor Discussion: https://postgr.es/m/CAJVSVGWGqY9YBs2EwtRUkbNv=hXkN8yRPOoD1wxE6COgvvrz5g@mail.gmail.com
2018-03-14Add Oracle like handling of char arrays.Michael Meskes
In some cases Oracle Pro*C handles char array differently than ECPG. This patch adds a Oracle compatibility mode to make ECPG behave like Pro*C. Patch by David Rader <davidr@openscg.com>
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.

2017-06-21Initial pgindent run with pg_bsd_indent version 2.0.Tom Lane
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.

2016-12-11Use "%option prefix" to set API names in ecpg's lexer.Tom Lane
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.

2016-03-23Move keywords.c/kwlookup.c into src/common/.Tom Lane
Now that we have src/common/ for code shared between frontend and backend, we can get rid of (most of) the klugy ways that the keyword table and keyword lookup code were formerly shared between different uses. This is a first step towards a more general plan of getting rid of special-purpose kluges for sharing code in src/bin/. I chose to merge kwlookup.c back into keywords.c, as it once was, and always has been so far as keywords.h is concerned. We could have kept them separate, but there is noplace that uses ScanKeywordLookup without also wanting access to the backend's keyword list, so there seems little point. ecpg is still a bit weird, but at least now the trickiness is documented. I think that the MSVC build script should require no adjustments beyond what's done here ... but we'll soon find out.
2015-03-26Tweak __attribute__-wrapping macros for better pgindent results.Tom Lane
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.
2015-03-11Add macros wrapping all usage of gcc's __attribute__.Andres Freund
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.
2014-10-22Small code cleanup.Michael Meskes
Declare static variable as static and external as extern.
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.
2013-11-19ecpg: Split off mmfatal() from mmerror()Peter Eisentraut
This allows decorating mmfatal() with noreturn compiler hints, leading to better diagnostics.
2011-04-28Use a macro variable PG_PRINTF_ATTRIBUTE for the style used for checking ↵Andrew Dunstan
printf type functions. The style is set to "printf" for backwards compatibility everywhere except on Windows, where it is set to "gnu_printf", which eliminates hundreds of false error messages from modern versions of gcc arising from %m and %ll{d,u} formats.
2011-04-10pgindent run before PG 9.1 beta 1.Bruce Momjian
2011-01-09There is no need to have to identical functions in ecpg thus removing one of ↵Michael Meskes
them.
2010-11-02Some cleanup in ecpg code:Michael Meskes
Use bool as type for booleans instead of int. Do not implicitely cast size_t to int. Make the compiler stop complaining about unused variables by adding an empty statement.
2010-09-20Remove cvs keywords from all files.Magnus Hagander
2010-01-26Applied patch by Boszormenyi Zoltan <zb@cybertec.at> to add out-of-scope ↵Michael Meskes
cursor support to native mode.
2010-01-05Applied patch by Boszormenyi Zoltan <zb@cybertec.at> to add sqlda support toMichael Meskes
ecpg in both native and compatiblity mode.
2009-11-26Added dynamic cursor names to ecpg. Almost the whole patch was done byMichael Meskes
Boszormenyi Zoltan, with only a minor tweak or two from me.
2009-09-08Remove outside-the-scanner references to "yyleng".Tom Lane
It seems the flex developers have decided to change yyleng from int to size_t. This has already happened in the latest release of OS X, and will start happening elsewhere once the next release of flex appears. Rather than trying to divine how it's declared in any particular build, let's just remove the one existing not-very-necessary external usage. Back-patch to all supported branches; not so much because users in the field are likely to care about building old branches with cutting-edge flex, as to keep OSX-based buildfarm members from having problems with old branches.
2009-07-14Tweak the core scanner so that it can be used by plpgsql too.Tom Lane
Changes: Pass in the keyword lookup array instead of having it be hardwired. (This incidentally allows elimination of some duplicate coding in ecpg.) Re-order the token declarations in gram.y so that non-keyword tokens have numbers that won't change when keywords are added or removed. Add ".." and ":=" to the set of tokens recognized by scan.l. (Since these combinations are nowhere legal in core SQL, this does not change anything except the precise wording of the error you get when you write this.)
2009-06-118.4 pgindent run, with new combined Linux/FreeBSD/MinGW typedef listBruce Momjian
provided by Andrew.
2009-06-03Clean up ecpg's use of mmerror(): const-ify the format argument, add anTom Lane
__attribute__() marker so that gcc can validate the format string against the actual arguments, get rid of overcomplicated and unsafe usage in base_yyerror().
2008-05-20Synced parser.Michael Meskes
Made ecpg parser use backend provided keyword list. Changed whenever test so exit value is 0.

2007-08-14Hopefully fixed missing CHAR_BIT symbolMichael Meskes
2007-08-14- Finished major rewrite to use new protocol versionMichael Meskes
- Really prepare statements - Added more regression tests - Added auto-prepare mode - Use '$n' for positional variables, '?' is still possible via ecpg option - Cleaned up the sources a little bit
2007-06-11Fixed one memory leak in descriptor code.Michael Meskes
Made sure ecpg deletes output file in case of an error.

2007-01-11Applied Joachim's patch for a --regression option.Michael Meskes
Made this option mark the .c files, so the environment variable is no longer needed. Created a special MinGW file with the special error message. Do not print port into log file when running regression tests.
