| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change sp_256to512z_mont_{mul,sqr}_8 to not require/zero upper 256 bits. There is only one place where we actually used that (and that's why there used to be zeroing memset of top half!). Fix up that place. As a bonus, 256x256->512 multiply no longer needs to care for "r overlaps a or b" case. This shrinks sp_point structure as well, not just temporaries. function old new delta sp_256to512z_mont_mul_8 150 - -150 sp_256_mont_mul_8 - 147 +147 sp_256to512z_mont_sqr_8 7 - -7 sp_256_mont_sqr_8 - 7 +7 sp_256_ecc_mulmod_8 494 543 +49 sp_512to256_mont_reduce_8 243 249 +6 sp_256_point_from_bin2x32 73 70 -3 sp_256_proj_point_dbl_8 353 345 -8 sp_256_proj_point_add_8 544 499 -45 ------------------------------------------------------------------------------ (add/remove: 2/2 grow/shrink: 2/3 up/down: 209/-213) Total: -4 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* | winansi: detect if running under WineRon Yorston2021-12-221-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Detect if running under Wine by checking for the wine_get_version function in ntdll.dll. This is how the Wine Developer FAQ suggests doing it. If running under Wine and not otherwise configured: - use ANSI emulation; - don't use alternate screen buffer in vi/less. Explicit settings of BB_SKIP_ANSI_EMULATION and BB_ALT_BUFFER will override the Wine defaults.
* | win32: fix implementation of readlink(2)Ron Yorston2021-11-251-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | Commit 35e32c2a71 (readlink(): do `NUL`-terminate the result) changed how our implementation of readlink(2) handles the case where the link is too long for the buffer. This broke xmalloc_readlink() which expects readlink(2) to behave as documented. As a results symbolic links with 80 or more characters didn't work properly. Revert the commit. (GitHub issue #237)

* | rpm: code shrinkRon Yorston2021-11-141-0/+4
| | | | | | | | | | | | | | Since the WIN32 implementation of chown(2) does nothing there's no point in calling it. Saves 112 bytes.
* | win32: rename mingw_spawn_1Ron Yorston2021-11-011-8/+8
| | | | | | | | | | | | | | | | | | | | The name of the function mingw_spawn_1() wasn't particularly meaningful. Remove its envp argument (as all of its current callers pass a NULL pointer) and rename it mingw_spawnvp() to better reflect what it does. The path search it performs isn't the standard one: it has features specific to busybox-w32.
* | win32: pass NULL to spawnve, not environRon Yorston2021-10-282-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | Building busybox-w32 for use with UCRT results in mysterious failures. (GitHub issue #234) These are somehow related to the environment values passed to spawnve. In several places the global environ pointer was being passed to spawnve so the child would inherit its environment from the parent. This can also be achieved by passing a NULL pointer. This prevents the failures in at least some cases and also makes the binary smaller.
* | win32: rmdir(2) shouldn't delete symlinksFRP-4487-gd239d2d52Ron Yorston2021-10-171-1/+8
| | | | | | | | | | | | | | | | On Linux rmdir(2) refuses to delete a symlink to a directory on the obvious grounds that a symlink isn't a directory. Windows' rmdir() is less discriminating. Make our implementation of rmdir(2) behave more like Linux.
* | win32: code shrinkRon Yorston2021-10-161-9/+16
| | | | | | | | | | | | | | | | | | There are a few places in mingw.c where we want to determine if a file is a symbolic link. Previously these called mingw_lstat() which collects far more information than is actually needed. Create a new is_symlink() function which does the minimum work necessary.
* | ash: display job id and pid of background commandsRon Yorston2021-10-141-1/+5
| | | | | | | | | | | | | | Several common shells display the job id and pid of background commands. Even the Unix V7 Bourne shell displays the pid. This is unrelated to whether job control is available or enabled.
* | ash: silence compiler warningsRon Yorston2021-10-142-3/+9
| | | | | | | | | | On 64-bit systems mingw-w64 defines pid_t as a 64-bit integer so some printf calls caused compiler warnings.
* | realpath: improved support for Windows pathsRon Yorston2021-10-134-10/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upstream commit 94eb1c4dc (libbb: better coreutils compatibility for realpath) made some changes to xmalloc_realpath_coreutils(). This now needs to be updated to handle Windows paths. - Expose the macro is_unc_path() and part of the recent change to bb_get_last_path_component_nostrip() as a separate funtion, get_last_slash(); - Convert a couple of errors relating to network filesystems to ENOENT; - Adjust xmalloc_realpath_coreutils() to handle Windows directory separators, relative paths and UNC paths.
