* | win32: revised implementation of setlinebuf(3)Ron Yorston2022-12-311-1/+1
| | | | | | | | | | | | | | | | | | Microsoft Windows' setvbuf() doesn't support line buffering and doesn't accept 0 as a valid value for the buffer size argument. Replace the old macro definition with an implementation that doesn't do anything. It's only used if debug is enabled in ash so there's no effect on the default build.
* | libbb: speed up bb_get_chunk_from_file()Ron Yorston2022-12-301-0/+9
| | | | | | | | | | | | | | | | Use _getc_nolock() in bb_get_chunk_from_file() and perform code page translation on the resulting string. This speeds up grep by another factor of two. (GitHub issue #278)
* | win32: speed up getc(3) wrapperRon Yorston2022-12-301-2/+2
| | | | | | | | | | | | | | | | The grep applet was found to be rather slow. A major reason for this is the implementation of getc(3). Using _getc_nolock() and inlining is_console_in() speeds things up by a factor of three. (GitHub issue #278)
* | win32: always allow d_type member of struct direntRon Yorston2022-12-222-4/+0
| | | | | | | | | | | | | | | | The d_type member of struct dirent is required by the implementation of glob(3). As a result it isn't possible to build the make applet unless FEATURE_EXTRA_FILE_DATA is configured. Allow d_type unconditionally.
* | win32: prevent stat(2) from updating access timesRon Yorston2022-12-221-4/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The WIN32 implementation of stat(2) reads the contents of some files to see if they're executable. This may update the file access time. Avoid this by a special call to SetFileTime() after opening the file. For details see: https://devblogs.microsoft.com/oldnewthing/20111010-00/?p=9433 https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-setfiletime File access times aren't updated by default in recent versions of Windows. This commit is only necessary if updating of file access times is explicitly enabled: fsutil behavior set DisableLastAccess 0
* | make: fixes to test scriptRon Yorston2022-12-121-0/+3
| | | | | | | | | | | | | | | | Unset MAKEFLAGS in the test script so it works if it's run using a version of make that has options which pdpmake doesn't understand. Return $FAILCOUNT as the exit status so the number of failures can be reported.
* | getopt: use name supplied with '-n' to report errorRon Yorston2022-11-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Windows: $ getopt -o a -n my_script -- -z getopt: unknown option -- z On Linux: $ getopt -o a -n my_script -- -z my_script: unknown option -- z The difference arises because the Mingw-w64 implementation of getopt(3) uses __argv[0] to report errors, not the first element of the argument array passed to it. Make __argv[0] point to the name supplied with the '-n' option to match behaviour when glibc getopt(3) is used. (GitHub issue #274)
* | make: add '-x' option to set pragmasRon Yorston2022-11-211-50/+92
| | | | | | | | | | | | Add a command line option to allow pragmas to be set. This is an alternative to the use of the .PRAGMA special target. The same pragmas are supported.
* | make: add .PRAGMA special targetRon Yorston2022-11-181-38/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the special target .PRAGMA. This allows certain features of the POSIX standard to be disabled when POSIX mode is being enforced. This is done by setting prerequisites of .PRAGMA, as follows: - macro names containing '-' are permitted with the 'macro_name' prerequisite; - target names containing '-' or '/' are permitted with the 'target_name' prerequisite; - the '#' character isn't treated as the start of a comment in a command line with the 'command_comment' prerequisite; - an empty suffix is permitted in a macro expansion of the form $(VAR:=.c) with the 'empty_suffix' prerequisite. Additionally the 'posix_202x' prerequisite enforces the future POSIX standard instead of the current one. In this case the 'macro_name' and 'target_name' pragmas aren't required as the future standard will allow the additional characters. .PRAGMA without any prerequisites restores the default behaviour.
* | build system: allow monochrome 'make menuconfig'Ron Yorston2022-11-161-0/+3
| | | | | | | | | | | | | | | | | | 'make menuconfig' uses a hardcoded colour palette which may be difficult to read. Add support for the 'COLORS' environment variable. Setting this to '0' will cause 'make menuconfig' to be displayed in black and white. (GitHub issue #273)
* | make: changes to suffix substitution in macro expansionRon Yorston2022-11-162-9/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The POSIX standard defines suffix substitution in macro expansion as taking the form: $(string1 [: subst1 =[ subst2 ]]) Since 'subst1' isn't bracketed a value must be supplied. Enforce this in POSIX mode. As a non-POSIX extension an empty 'subst1' is permitted with 'subst2' being added to all words unconditionally. If both 'subst1' and 'subst2' are empty the words are returned unchanged.
* | make: show location of errors during buildRon Yorston2022-11-161-15/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Error messages only displayed the location of an error while the makefile was being parsed. Store the location (makefile name and line number) of each command line. This allows location information to be displayed in errors encountered while targets are being built. Take this Makefile, for example: target: @echo $(hello Previously this would display: make: unterminated variable '$(hello' Now it shows: make: (Makefile:2): unterminated variable '$(hello'
* | make: fix typo in help textRon Yorston2022-11-141-2/+2

* | win32: native make menuconfig: support searchAvi Halachmi (:avih)2022-11-131-5/+21
| | | | | | | | | | | | | | Previously, pressing slash to search at the menu aborted the menu program ('mconf'), because regexp is not available with native mingw. Now it works, but the search is of plain string rather than regexp.
* | make: use correct test for valid macro nameRon Yorston2022-11-132-1/+14
| | | | | | | | | | The test for valid macro names in POSIX mode was incorrect: it shouldn't have allowed '-'.
* | make: pdpmake needs long filename support in ar tooRon Yorston2022-11-131-1/+1
| | | | | | | | | | | | Commit f261d2d27 (make: make + sh configuration) added a 'pdpmake' alias for 'make'. It omitted to reference PDPMAKE as a dependency for FEATURE_AR_LONG_FILENAMES.
