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.

2017-04-11Remove symbol WIN32_ONLY_COMPILERMagnus Hagander
This used to mean "Visual C++ except in those parts where Borland C++ was supported where it meant one of those". Now that we don't support Borland C++ anymore, simplify by using _MSC_VER which is the normal way to detect Visual C++.

2016-08-30Fix a bunch of places that called malloc and friends with no NULL check.Tom Lane
Where possible, use palloc or pg_malloc instead; otherwise, insert explicit NULL checks. Generally speaking, these are places where an actual OOM is quite unlikely, either because they're in client programs that don't allocate all that much, or they're very early in process startup so that we'd likely have had a fork() failure instead. Hence, no back-patch, even though this is nominally a bug fix. Michael Paquier, with some adjustments by me Discussion: <CAB7nPqRu07Ot6iht9i9KRfYLpDaF2ZuUv5y_+72uP23ZAGysRg@mail.gmail.com>
2016-04-07Remove redundant message in AddUserToTokenDacl().Noah Misch
GetTokenUser() will have reported an adequate error message. These error conditions almost can't happen, so users are unlikely to observe this change. Reviewed by Tom Lane and Stephen Frost.
2016-04-02Refer to a TOKEN_USER payload as a "token user," not as a "user token".Noah Misch
This corrects messages for can't-happen errors. The corresponding "user token" appears in the HANDLE argument of GetTokenInformation().

2015-01-08On Darwin, detect and report a multithreaded postmaster.Noah Misch
Darwin --enable-nls builds use a substitute setlocale() that may start a thread. Buildfarm member orangutan experienced BackendList corruption on account of different postmaster threads executing signal handlers simultaneously. Furthermore, a multithreaded postmaster risks undefined behavior from sigprocmask() and fork(). Emit LOG messages about the problem and its workaround. Back-patch to 9.0 (all supported versions).

2014-02-17Prevent potential overruns of fixed-size buffers.Tom Lane
Coverity identified a number of places in which it couldn't prove that a string being copied into a fixed-size buffer would fit. We believe that most, perhaps all of these are in fact safe, or are copying data that is coming from a trusted source so that any overrun is not really a security issue. Nonetheless it seems prudent to forestall any risk by using strlcpy() and similar functions. Fixes by Peter Eisentraut and Jozef Mlich based on Coverity reports. In addition, fix a potential null-pointer-dereference crash in contrib/chkpass. The crypt(3) function is defined to return NULL on failure, but chkpass.c didn't check for that before using the result. The main practical case in which this could be an issue is if libc is configured to refuse to execute unapproved hashing algorithms (e.g., "FIPS mode"). This ideally should've been a separate commit, but since it touches code adjacent to one of the buffer overrun changes, I included it in this commit to avoid last-minute merge issues. This issue was reported by Honza Horak. Security: CVE-2014-0065 for buffer overruns, CVE-2014-0066 for crypt()

2013-10-18Switch dependency order of libpgcommon and libpgportPeter Eisentraut
Continuing 63f32f3416a8b4f8e057dc184e8e8eae734ccc8a, libpgcommon should depend on libpgport, but not vice versa. But wait_result_to_str() in wait_error.c depends on pstrdup() in libpgcommon. So move exec.c and wait_error.c from libpgport to libpgcommon. Also switch the link order in the place that's actually used by the failing ecpg builds. The function declarations have been left in port.h for now. That should perhaps be separated sometime.
