Guillem Jover 304a1f83 2024-01-08T23:37:43 doc: Use macOS to refer to the operating system This is the correct spelling, instead of capitalizing it.
Guillem Jover ecb44e16 2023-11-14T19:15:11 Do not add a pointer to the NULL constant Warned-by: cppcheck (nullPointerArithmetic)
Guillem Jover 459b7f7d 2023-11-14T19:09:25 Do not confuse code analyzers with out-of-bounds array access look alike The code is only getting the address, but we might be performing an addressing that is out-of-bounds. Avoid it and use the address form instead. Warned-by: cppcheck (objectIndex)
Guillem Jover 6777eb62 2023-07-27T13:57:51 pwcache: Do not declare uidtb and gidtb when not used When the system provides implementations for user_from_uid() or group_from_gid() we are not using these variables, so better not declare them. Fixes: commit 21d12b02112097f0c195dceb1892c95b7b957b36
Guillem Jover d4e0cdc9 2023-07-27T13:39:00 fgetln: Include <stdio.h> after <sys/*> The <sys/*> headers tend to define things that might be used by other headers, so while they should be self-contained, it is better to simply include them first.
Guillem Jover cf61ebb8 2023-04-22T20:47:20 build: Do not build the progname module if it is not needed This was made conditional, but the code part was accidentally left untouched due to having ported it locally to use __progname, which caused build failures on the stock repo. Fixes: commit 046621d7967e7a0f08ae988bcf7e4cd1b6cf204c
Guillem Jover 73b25a8f 2023-04-23T02:04:47 build: Sort entries alphabetically
Guillem Jover 5434ba16 2023-04-23T02:05:04 build: Conditionalize wcslcpy() and wcslcat() functions on macOS These functions are provided by the system libc.
Guillem Jover dc1bd1a2 2023-04-23T02:00:10 build: Conditionalize only id-from-name functions not the entire pwcache On macOS the name-from-id functions are present, but not the id-from-name ones, so we want to provide those instead of suppressing the entire file.
Guillem Jover 8f998d1d 2023-04-22T20:23:08 progname: Include <procinfo.h> if available We need this header on AIX. Missed transplanting the code from the AIX porting system. Fixes: commit 9fa06763a1afe0946a3a20e5bbdba72885cbade5
Guillem Jover 6385ccc9 2023-04-18T03:58:24 build: Conditionalize bsd_getopt() on macOS The system library provides a getopt() with BSD semantics.
Guillem Jover 9fa06763 2023-04-18T00:44:49 Port getprogname() to AIX Get the program name from the COMM field from the proc filesystem. We could use instead the information from the psinfo binary file under /proc, but that seems to have a shorter string limit.
Guillem Jover 92337b15 2023-04-17T23:59:03 Make getprogname() porting mandatory Although the function is documented as possibly returning NULL if it cannot find a known source of information, we should still at least attempt to port it to any supported system, and otherwise explicitly mark it as not implementable for such systems if that was to be the case.
Guillem Jover c1206817 2023-04-18T00:47:12 Move the version script comments before the symbols When generating the .sym export file from the .map file, we are not stripping these comments that are part of the same line as the symbol, which causes ld(1) implementations to error out. Moving them before the symbols avoids the need to strip them, as we are only keeping actual symbol lines.
Guillem Jover 21d12b02 2023-04-04T23:59:05 build: On macOS do not build functions provided by the system We have never built before on macOS, so we can exclude all the functions that are currently provided in the system. Closes: #1 Closes: !3
Guillem Jover bc65806c 2023-04-06T23:05:27 build: Select whether to include funopen() in the build system This makes sure we include it when expected, alongside the man pages, and the test cases, and do not accidentally break the ABI if the system starts providing such interface.
Guillem Jover e0976d7e 2023-04-02T22:33:25 build: Add a new libbsd_strong_alias() macro and switch users to it We had several cases of code needing a strong alias, so we switch those to use the new macro. This covers systems that support the alias attribute and others such as macOS where we need to use assembler directives to add the alias as the attribute is not supported.
Guillem Jover 49c7dd1c 2023-04-02T22:32:11 build: Only emit link warnings for ELF objects
Guillem Jover 8622767a 2023-04-11T00:24:13 build: Use an export symbols file if there is no version script support We generate the symbol list from the version script to avoid repeating ourselves and potentially getting the lists out-of-sync.
Guillem Jover 8f610364 2023-04-11T03:03:54 build: Add -no-undefined libtool flag We have no need for undefined symbols, so we can let the shared library build even on systems without support for undefined symbols.
Guillem Jover ae7942ba 2023-04-11T03:02:30 build: Do not override the default DEPENDENCIES for libbsd Extend it instead via EXTRA_*_DEPENDENCIES, to make sure that we preserve the builtin library dependencies generated from LIBADD.
Guillem Jover a5faf170 2023-04-01T12:46:49 Only use <stdio_ext.h> if present
Guillem Jover 06e8a1b2 2023-04-01T12:45:04 Define _NSIG if it is not defined by the system At least on macOS this macro is not defined.
Guillem Jover 44824aca 2023-04-01T12:41:42 Declare environ if the system does not do so The environ variable is supposed to be defined by the code using it, but on glibc-based systems it will get defined if we request it, by including <unistd.h> and defining _GNU_SOURCE.
Guillem Jover 1fb6c3f4 2023-04-10T23:10:40 Use lockf() when flock() is not available On Solaris flock() is not available, and we should use instead lockf() or fcntl().
Khem Raj ec88b7bb 2022-12-15T09:02:22 funopen: Replace off64_t with off_t in funopen_seek() AC_SYS_LARGEFILE in configure.ac is setting needed defines to make 64bit off_t on relevant platforms. Fixes build on musl: | src/funopen.c:68:28: error: unknown type name 'off64_t'; did you mean 'off_t'? | funopen_seek(void *cookie, off64_t *offset, int whence) | ^~~~~~~ | off_t Closes: !24 Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Guillem Jover <guillem@hadrons.org>
Guillem Jover e5089628 2022-11-23T23:31:54 build: Do not require funopen() to be ported This function cannot be easily and (more importantly) correctly ported without cooperation from the libc stdio layer. We already document that users should be prepared to have the function not available on some platforms and that they should ideally switch their code to other more portable and better interfaces. Instead of making the build fail, and requiring porters to add exceptions for something that most probably cannot be ported correctly anyway, simply print a warning and let it build. This will not be a regression because on those systems libbsd would have never been built before. Prompted-by: Jens Finkhaeuser <jens@finkhaeuser.de>
Guillem Jover 00b538ff 2022-11-23T23:28:34 build: Terminate lists in variables with «# EOL» This means we can add a trailing «\» to every element, so that they can be removed without requiring modification of other lines, and can be easily sorted. Replace the old usage of $(nil) which could possibly end up with junk added if such variable is ever defined, in the environment.
Guillem Jover 28298ac0 2022-10-05T01:35:08 doc: Switch references from pkg-config to pkgconf The former used to be the reference implementation, but it has been stagnant to the point of not showing much signs of life. Switch to the currently active and more complete implementation for references.
Guillem Jover be327c6e 2022-08-24T01:58:58 fgetwln: Add comment about lack of getwline(3) for recommendation Ideally we'd recommend getwline(3), but unfortunately even though it was part of the ISO/IEC TR 24731-2:2010 draft, it did not make it into C11 and is not widely implemented.
Guillem Jover a14612d9 2022-08-23T23:49:34 setmode: Dot not use saveset after free While we are only doing a pointer difference and not dereferencing it, it's easier and more correct to do the pointer difference before passing it to reallocarray(). Warned-by: gcc

Guilherme Janczak e5ed5fdd 2021-12-31T08:25:08 Remove arc4random() OpenBSD support The arc4random() support for OpenBSD does not build. The intention was to include any portability code so that the library could be easily ported to such systems, but it makes little sense to build it on OpenBSD where most of the functionality will be already present, or the software would have been ported anyway.

Guillem Jover 48107fc8 2021-11-28T23:19:16 build: Clarify link-time warnings Mention the involved function instead of stating an implicit "this function". Mention libbsd when proposing using an alternative libmd to make the context clear.
Guillem Jover e7cf8c57 2021-11-28T22:44:08 Switch md5 compatibility logic back to direct linking When using the recent dlsym() based wrapper, we are not requiring any symbol from libmd, as we resolve those dynamically at run-time. We were ending up linking against libmd because in another part of the code we require (depending on the architecture) the SHA512 functions for the getentropy() local implementation. But that function might be provided by the system libc on some systems, which means we end up not linking against libmd at all. To solve this we go back to the previous simpler solution of linking directly, which had the main drawback of then making programs fail to link when not specifying -lmd (on platforms that need it). And then switch the .so link point from a symlink to a linker script, so that we can inject the -lmd library as-needed. This is similar to what glibc is doing. Fixes: commit 31f034e3862debda8615a449b1c11c4d6920dcc7
Guillem Jover 25d35625 2021-11-28T22:40:58 build: Split libmd dependency due to MD5 functions from SHA requirements To be able to rework the md5 deprecation logic, we need to detangle when we depend on libmd due to requiring MD5 functions, which might be otherwise provided by libc, or when we require SHA functions for the internal getentropy() implementation.
Guillem Jover 500b3080 2021-11-28T22:34:59 build: Add new libbsd_symver_weak() macro We will use it for the reworked md5 deprecation logic.

Guillem Jover 31f034e3 2021-02-09T05:57:37 Switch libmd wrapper to use dlsym() Switch from the previous versioned symbol implementation which required users to also link against the message digest provider explicitly, or they would fail to find the symbols, to an implementation that loads the symbols from the linked library providing the functions using dlsym(), thus preserving backwards compatibility.

[L] <https://refspecs.linuxfoundation.org/LSB_5.0.0/LSB-Core-generic/LSB-Core-generic/baselib---register-atfork.html> [P] <http://austingroupbugs.net/view.php?id=851> One problem is that we were using it whenever __GLIBC__ is defined, which is supposed to be defined only on an actual glibc, but uClibc defines that macro, but it does not provide the symbol on its noMMU variant. We add a new configure check that will try to link a program that uses that symbol to make sure it is present. Closes: !2 Reported-by: Fabrice Fontaine <fontaine.fabrice@gmail.com>

Guillem Jover 5e0998fa 2018-06-09T00:08:14 Remove dead code in vis The loop only executes while len > 0, and the trinary operator in the function argument is checking against len >= 1 which will always be true. Warned-by: coverity
Guillem Jover 8e2d5504 2018-06-06T05:41:34 Fix vis family of functions to not leak The code uses an internal helper function to avoid code repetition. But to get there, the function takes a pointer to a pointer, so that the few functions that require returning an allocated buffer can get hold of it this way. The problem is that the user might pass a NULL pointer and trigger an internal allocation even if the functions are not expected to do so. Add a new internal helper for non-allocations, that will assert that condition, and make any other function that requires this behavior call this one instead. Warned-by: coverity

Guillem Jover e4e15ed2 2018-05-22T13:50:44 Fix strnvis() and strnunvis() NetBSD ABI break The NetBSD implementations have different prototypes to the ones coming from OpenBSD, which will break builds, and have caused segfaults at run-time. We provide now both interfaces with different prototypes as different version nodes allow selecting them at compile-time, defaulting for now to the OpenBSD one to avoid build-time breakage, while emitting a compile-time warning. Later on, in 0.10.0, we will be switching the compile-time default to the NetBSD version. Ref: http://gnats.netbsd.org/44977 Fixes: https://bugs.debian.org/899282
