2017-06-21Phase 3 of pgindent updates.Tom Lane
Don't move parenthesized lines to the left, even if that means they flow past the right margin. By default, BSD indent lines up statement continuation lines that are within parentheses so that they start just to the right of the preceding left parenthesis. However, traditionally, if that resulted in the continuation line extending to the right of the desired right margin, then indent would push it left just far enough to not overrun the margin, if it could do so without making the continuation line start to the left of the current statement indent. That makes for a weird mix of indentations unless one has been completely rigid about never violating the 80-column limit. This behavior has been pretty universally panned by Postgres developers. Hence, disable it with indent's new -lpl switch, so that parenthesized lines are always lined up with the preceding left paren. 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.

2017-06-21Phase 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.

2017-02-25Remove useless duplicate inclusions of system header files.Tom Lane
c.h #includes a number of core libc header files, such as <stdio.h>. There's no point in re-including these after having read postgres.h, postgres_fe.h, or c.h; so remove code that did so. While at it, also fix some places that were ignoring our standard pattern of "include postgres[_fe].h, then system header files, then other Postgres header files". While there's not any great magic in doing it that way rather than system headers last, it's silly to have just a few files deviating from the general pattern. (But I didn't attempt to enforce this globally, only in files I was touching anyway.) I'd be the first to say that this is mostly compulsive neatnik-ism, but over time it might save enough compile cycles to be useful.

2015-01-24Replace a bunch more uses of strncpy() with safer coding.Tom Lane
strncpy() has a well-deserved reputation for being unsafe, so make an effort to get rid of nearly all occurrences in HEAD. A large fraction of the remaining uses were passing length less than or equal to the known strlen() of the source, in which case no null-padding can occur and the behavior is equivalent to memcpy(), though doubtless slower and certainly harder to reason about. So just use memcpy() in these cases. In other cases, use either StrNCpy() or strlcpy() as appropriate (depending on whether padding to the full length of the destination buffer seems useful). I left a few strncpy() calls alone in the src/timezone/ code, to keep it in sync with upstream (the IANA tzcode distribution). There are also a few such calls in ecpg that could possibly do with more analysis. AFAICT, none of these changes are more than cosmetic, except for the four occurrences in fe-secure-openssl.c, which are in fact buggy: an overlength source leads to a non-null-terminated destination buffer and ensuing misbehavior. These don't seem like security issues, first because no stack clobber is possible and second because if your values of sslcert etc are coming from untrusted sources then you've got problems way worse than this. Still, it's undesirable to have unpredictable behavior for overlength inputs, so back-patch those four changes to all active branches.

This includes removing tabs after periods in C comments, which was applied to back branches, so this change should not effect backpatching.
2014-05-06Fix handling of array of char pointers in ecpglib.Michael Meskes
When array of char * was used as target for a FETCH statement returning more than one row, it tried to store all the result in the first element. Instead it should dump array of char pointers with right offset, use the address instead of the value of the C variable while reading the array and treat such variable as char **, instead of char * for pointer arithmetic.

2014-03-01Various Coverity-spotted fixesStephen Frost
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.
2014-01-16Split ecpg_execute() in constituent partsAlvaro Herrera
Split the rather long ecpg_execute() function into ecpg_build_params(), ecpg_autostart_transaction(), a smaller ecpg_execute() and ecpg_process_output(). There is no user-visible change here, only code reorganization to support future patches. Author: Zoltán Böszörményi Reviewed by Antonin Houska.

2014-01-16Split ECPGdo() in constituent partsAlvaro Herrera
This splits ECPGdo() into ecpg_prologue(), ecpg_do() and ecpg_epilogue(), and renames free_params() into ecpg_free_params() and exports it. This makes it possible for future code to use these routines for their own purposes. There is no user-visible functionality change here, only code reorganization.
