| * httpd: Don't add Date header to responseSergey Ponomarev2020-08-151-2/+16
| | | | | | | | | | | | | | | | | | RFC 2616 sec. 14.18 says that server MUST send Date header. But in fact the header make sense only for Cache-Control and can be omitted. In the same time the Date eats power, CPU and network resources which are critical for embedded systems.

| * httpd: Update to HTTP/1.1Sergey Ponomarev2020-08-151-8/+8
| | | | | | | | | | | | | | | | | | HTTP v1.1 was released in 1999 year and it's time to update BB HTTPD. Browsers may behave badly with HTTP/1.0 E.g. Chrome does not send the If-None-Match header with ETag. Signed-off-by: Sergey Ponomarev <stokito@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| * build system: drop PLATFORM_LINUXRon Yorston2020-08-13109-146/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PLATFORM_LINUX is a hidden configuration option which is disabled by default and enabled at over a hundred locations for features that are deemed to be Linux specific. The only effect of PLATFORM_LINUX is to control compilation of libbb/match_fstype.c. This file is only needed by mount and umount. Remove all references to PLATFORM_LINUX and compile match_fstype.c if mount or umount is enabled. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Duplicate options are currently overridden (only the last option is kept). This leads to unexpected behavior when using long options. The patch adds support for long options in compliance with RFC 3396.

| * crontab: Fix -e with editors saving using renaming strategyGray Wolf2020-07-111-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some editors (like vim) use renaming strategy to save file. That means they save a file to some random name and then rename it to final location. The advantage is that such save is atomic. However, crontab -e holds open fd to the temporary file, meaning it never sees the changes. The temporary file needs to be re-opened after the editor terminates for the changes to properly save.

* | win32: code shrink Unix-style path handlingRon Yorston2020-08-237-96/+50
| | | | | | | | | | | | | | | | Replace auto_add_system_drive() with alloc_system_drive() which leaves space for a possible filename extension. This makes it possible to drop alloc_win32_extension() and auto_win32_extension(). Saves 144 bytes.
* | ash: use stack, not heap, to add system drive to pathRon Yorston2020-08-211-16/+27
| | | | | | | | Make the code a bit tidier, no change to functionality or size.
* | win32: allow putenv() to set empty valuesRon Yorston2020-08-211-4/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | WIN32 _putenv() can't set an environment variable with an empty value because 'NAME=' is treated as a request to delete the variable. Allow mingw_putenv() to set an empty value by first setting a fake value and then truncating it. This problem has always been present in mingw_putenv() but it became particularly pressing when ash started treating all applets as NOEXEC. The environment of NOEXEC applets is created by clearing the current environment and using putenv() to set a new one from the shell variables. Empty variable were not being set. See GitHub issue #197.
* | win32: env.c code shrink and clarificationRon Yorston2020-08-211-7/+6
| | | | | | | | | | | | | | | | Use xasprintf() to create string in unsetenv(). Clarify when we're using WIN32 _putenv(). No change in functionality; saves 16 bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally 'ls' displays paths exactly as the user enters them: $ ls .//file .//file In busybox-w32 paths using backslash as a separator are displayed in a form that can't be reused as input to the shell: $ ls .\\file .\file Allow backslashes to be replaced with forward slashes if the environment variable BB_FIX_BACKSLASH is set to 1. See GitHub issue #196.

| | | | | | | | | | If a custom installation directory is specified try to create it. Don't worry if we can't, we'll find out when the links fail.
* | busybox: add option to install to Unix-style pathsRon Yorston2020-08-142-12/+35
| | | | | | | | | | The command 'busybox --install -u' installs links to Unix-style paths in the system drive.
* | win32: use built-in applets for non-existent binaries with Unix-style pathsRon Yorston2020-08-135-11/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Shell scripts moved from Unix may contain hard-coded paths to binaries such as /bin/sh. A recent commit made it possible to execute such binaries reliably, but that does require them to be installed. As an alternative solution: if a binary with a standard Unix path prefix can't be found but is available as a built-in applet, run the applet. Add the function unix_path() to detect paths starting with /bin, /usr/bin, /sbin or /usr/sbin. Use this function in: - the 'which' applet - shellexec(), describe_command() and find_command() in ash - mingw_spawn_1() See GitHub issue #195.
* | httpd: code shrinkRon Yorston2020-08-131-3/+2
| | | | | | | | Use the new need_system_drive() function in httpd. Saves 16 bytes.
* | win32: handle Unix-style absolute paths for executablesRon Yorston2020-08-137-4/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As noted in commit 548ec7045 (win32: interpret absolute paths as relative to %SYSTEMDRIVE%) a path starting with a '/' in the Unix world is treated as relative to the current drive by Windows. To avoid ambiguity that commit considered certain such paths to be relative to %SYSTEMDRIVE%. Extend this to paths representing executables. Add the functions need_system_drive() and auto_add_system_drive() to detect the need for a system drive prefix and to add it if necessary. Use these functions in: - the 'which' applet - the find_executable() function - tab-completion code - PATH look-up, shellexec(), describe_command() and find_command() in ash - parse_interpreter() and mingw_spawn_1() With these changes executable paths starting with a slash are handled consistently, whatever the current drive.
* | win32: use a static buffer in get_system_drive()Ron Yorston2020-08-134-18/+16
| | | | | | | | | | | | | | Allocate static storage for the system drive string instead of making a new allocation on every call. This is easier to manage. Adds 16 bytes.
* | win32: code shrinkRon Yorston2020-08-135-7/+17
| | | | | | | | | | | | | | | | | | | | Add a new function, has_path(), to detect that an executable name doesn't require a path look-up. Also, since is_absolute_path() is now only used in shell/ash.c move its definition there from include/mingw.h. Saves 128 bytes.
* | which: handle paths of form 'c:path'Ron Yorston2020-08-131-2/+5
| | | | | | | | | | | | | | Add another case where paths of the form 'c:path' need special treatment. Adds 16 bytes.
* | win32: move code to fork (de)compressor to a functionRon Yorston2020-08-054-38/+29
| | | | | | | | | | | | | | | | Use a new common function, mingw_fork_compressor(), to implement fork_transformer() in open_transformer.c and vfork_compressor() in tar.c. Saves 160 bytes.
* | which: rearrange conditional compilationRon Yorston2020-08-041-1/+6
| | | | | | | | The code for standalone shell mode should only be built for WIN32.
* | win32: update strptime(3) implementationRon Yorston2020-08-031-12/+19
| | | | | | | | | | | | | | | | | | | | Update to latest code from gnulib. This adds a '%q' (quarter) field descriptor. Remove the 'neg' variable from the code to handle the '%z' (timezone) field descriptor. Since our struct tm lacks a tm_gmtoff member '%z' is only supported "for reasons of symmetry". Since the computed value is never used there's no need to negate it.
* | build system: reinstate PLATFORM_LINUXRon Yorston2020-08-032-0/+2
| | | | | | | | | | | | | | Removing 'select PLATFORM_LINUX' from ps and stat has no material effect: it just causes match_fstype.o to be built needlessly. Remove this difference from upstream.
* | install: enable in default buildRon Yorston2020-08-032-10/+14
| | | | | | | | | | Attempting to set file ownership and permissions may not work exactly as on *NIX.
* | win32: code shrink kill(2)Ron Yorston2020-07-253-33/+19
| | | | | | | | | | | | | | | | - Drop exit_code argument from kill_SIGTERM_by_handle() - Pass signal number rather than exit code to other functions - Merge kill_SIGKILL() and kill_SIGTEST() Saves 112 bytes.

* | ts: correct output in 64-bit buildRon Yorston2020-07-191-0/+8
| | | | | | | | | | | | | | | | | | | | | | ts failed to output the correct time when built for 64-bit Windows. In 64-bit builds time_t is a 64-bit quantity whereas the tv_sec member of struct timeval is 32-bit. https://sourceforge.net/p/mingw-w64/bugs/783/ Use a temporary time_t value in 64-bit builds.
* | win32: alter build flagsFRP-3532-g01a256149Ron Yorston2020-07-091-1/+1
| | | | | | | | | | Add -fno-builtin-strndup to the build flags, otherwise builds with link-time optimisation can't find strndup.
