2023-11-28newlib: filter out versions from newlib.h to simplify autoreconfMike Frysinger2-2/+5
We've been manually editing newlib.hin after generating it with autoheader to drop the version defines that we keep in the separate _newlib_version.h header. This is confusing for people, and is an easy source of mistakes/errors. Since we're already running sed on newlib.h during configure to filter out defines we don't want to expose, add the version macros there too. This way we don't have to manually edit newlib.hin. This simplifies the autoreconf step in exchange for a slightly more complicated configure+sed step, but seems worth the trade-off.
2023-11-28Cygwin: fallocate(2): handle FALLOC_FL_PUNCH_HOLE and FALLOC_FL_ZERO_RANGECorinna Vinschen5-68/+302
Split fhandler_disk_file::fallocate into multiple methods, each implementing a different aspect of fallocate(2), thus adding FALLOC_FL_PUNCH_HOLE and FALLOC_FL_ZERO_RANGE handling. For more correctly implementing posix_fallocate(3) semantics, make sure to re-allocate holes in the given range if the file is sparse. While at it, change the way checking when to make a file sparse. The rule is now, make file sparse if the hole created by the action spans at least one sparse block, taking the allocation granularity of sparse files into account.

2023-11-28Cygwin: open(2): reset sparseness on O_TRUNCated filesCorinna Vinschen2-0/+12
open(2) implements O_TRUNC by just reducing the size of the file to 0, to make sure EAs stay available. Turns out, file sparseness is not removed this way either, so add code to do just that.

2023-11-28Cygwin: posix_fallocate: return ENODEVCorinna Vinschen3-1/+8
The fhandler method ftruncate returns either EISDIR if it has been called on directories, or EINVAL if called on files other than regular files. This matches what ftruncate(2) is supposed to return, but it doesn't match posix_fallocate(3), which is supposed to return ENODEV in both cases. To accomplish that, return ENODEV from fhandler_base::ftruncate() and convert it to EINVAL in ftruncate(2). In posix_fallocate(3), convert EISDIR to ENODEV.

2023-11-25Cygwin: lseek: check for file sparseness, not for mount point sparsenessCorinna Vinschen1-1/+1
The code introducing the lseek(2) code for the GNU extensions SEEK_DATA and SEEK_HOLE accidentally checks if the mount point has the "sparse" flag set and, if not, emulates SEEK_DATA/SEEK_HOLE per the Linux specs. However, the mount point "sparse" flag only determines whether files should be made sparse or not. Files may be sparse independently of that, obviously. Fix that by checking for the FILE_ATTRIBUTE_SPARSE_FILE attribute instead.

2023-11-24newlib: nl_langinfo: Fix a bug of time stuff.Takashi Yano1-4/+4
Previously, e.g. nl_langinfo(_NL_TIME_WMONTH_1) returns "February" due to the bug. Similarly, nl_langinfo(_NL_TIME_WWDAY_1) returns "Mon". This occurs because wide char month and weekday arrays are pointed off-by-one (e.g. the array wmon[12] is reffered as wmon[1-12] rather than wmon[0-11]). This patch fixes that.

2023-11-20stdio: Fix bugs in commit 3d94e07c49b5Takashi Yano27-12/+43
The commit 3d94e07c49b5 has a few bugs which cause testsuite failure in libstdc++. This is due to excess orientation check in __srefill_r() and _ungetc_r(). Further, sscanf() family also calls ssvfscanf() family with fp->_file == -1. This causes undesired orientation set/check for sscanf() family. This patch fixes these problems. Also, as in GLibC, do not set orientation in ungetc, and only set, but do not check orientation in ungetwc. Fixes: 3d94e07c49b5 ("newlib: libc: Fix crash on fprintf to a wide-oriented stream.")

2023-11-17v{fs}printf/v{fs}wprintf: create external output helpersCorinna Vinschen12-265/+467
So far, the printf family of functions has two output helper functions called __sprint_r and __sfputs_r. Both are called from all variants of vfprintf as well as vfwprintf. There are also analogue helper functions for the string-creating functions vsprintf/vswprintf called __ssprint_r and __ssputs_r. However, the helpers are built once when building vfprintf/vsprintf with the INTEGER_ONLY flag, and then they are part of the vfiprintf.c and vsiprintf.c files. The problem is this: Even if a process only calls vfwprintf or the non-INTEGER_ONLY vfprintf it will always have to include the INTEGER_ONLY vfiprintf. Otherwise the helper functions are undefined. Analogue for the string-creating functions. That's a useless waste of space by including one (or two) big, unused function, if newlib is linked in statically. Create new files to define the printf output helpers separately and split them into byte-oriented and wide-char-oriented functions. This allows to link only the required functions. Also, simplify the string output helpers and fix a potential (but unlikely) buffer overflow in __ssprint_r.

2023-11-10newlib: libc: Fix crash on fprintf to a wide-oriented stream.Takashi Yano19-40/+92
Previously, fprintf() on a wide-oriented stream crashes or outputs garbage. This is because a narrow char string which can be odd bytes in length is cast into a wide char string which should be even bytes in length in __sprint_r/__sfputs_r based on the __SWID flag. As a result, if the length is odd bytes, the reading buffer runs over the buffer length, which causes a crash. If the length is even bytes, garbage is printed. With this patch, any output to the stream which is set to different orientation fails with error just like glibc. Note that it behaves differently from other libc implementations such as BSD, musl and Solaris.

2023-10-31Cygwin: let feraiseexcept actually raise an exceptionCorinna Vinschen2-1/+4
The exception handling inside of Cygwin functions marked as SIGFE covers exceptions and lets the library code handle them gracefully. If these functions want to raise an exception, they have to send a signal explicitely via raise(3). That's not what we want in feraiseexcept(). It triggers a floating point exception explicitely by calling the i387 op "fwait". Being marked as SIGFE, this exception will be suppressed and the normal exception handling won't kick in. Fix this by moving feraiseexcept into the NOSIGFE realm. Fixes: 0f81b5d4bcaa ("* Makefile.in (DLL_OFILES): Add new fenv.o module.") Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2023-10-30Cygwin: cwd: avoid releasing the cwdstuff SRW Lock twiceCorinna Vinschen2-2/+4
cwdstuff::set has a code snippet handling the case where a process can't create a handle to a directory, e. g., due to permissions. Commit 88443b0a22589 ("cwdstuff: Don't leave from setting the CWD prematurely on init") introduced a special case to handle this situation at process initialization. It also introduces an early mutex release, which is not required, but ok, because we're in the init phase. Releasing the mutex twice is no problem since the mutexes are recursive. Fast forward to commit 0819679a7a210 ("Cygwin: cwd: use SRWLOCK instead of muto"). The mechanical change from a recursive mutex to a non-recursive SRWLOCK failed to notice that this very specific situation will release the SRWLOCK twice. Remove the superfluous release action. While at it, don't set dir to NULL, but h, since dir will get the value of h anyway later on. Setting h to NULL may not be necessary, but better safe than sorry.
