* crond: fix reboot special timeRon Yorston2026-05-191-0/+31
| | | | | | | | | | | | | | | The 'reboot' special time didn't work because the file to check for a reboot couldn't be created. And in any case, the mechanism used on Linux wouldn't work: Windows has no /var/run directory which is cleared on reboot. The crond.reboot file is now placed in the cron directory. If it doesn't exist when crond starts, it's created but the reboot job (if any) isn't run. If the file exists its modification time is compared with the time of the current boot. If it's older update its time and run the reboot job. Adds 144-224 bytes.
* crond: drop '-S' optionRon Yorston2026-05-191-5/+22
| | | | | | | Since we don't use syslog on Windows there's no point in having an option to set it. Log to stderr by default instead. Saves 88-96 bytes.
* crond,crontab: executable-relative cron directoriesRon Yorston2026-05-192-4/+40
| | | | | | | | | | | | | | | | | Some users want a 'portable' busybox-w32 installation on removable media. To help with this, certain files can be positioned relative to the location of the executable. crond and crontab now look for var/spool/cron/crontabs relative to the binary, and use that as their working directory if it exists. If it doesn't, fall back to the hardcoded absolute path. The '-c' command line option can still be used to override the automatic choice. The '-c' option in crond now updates the cron directory variable as well as that for crontabs. Adds 128-144 bytes.
* crond: build tweaksRon Yorston2026-05-031-2/+2
| | | | | | | | | | | | | | | Using 'depends on FEATURE_SYSLOG' is unreliable because FEATURE_SYSLOG can't be set directly. A POSIX build with all applets that need syslog disabled *except* crond may fail. Revert to using 'select FEATURE_SYSLOG' in crond and exclude the unused syslog code on Windows. If crond is unable to run sendmail report this in the error message. Update all default Windows configurations. (GitHub PR #561)

| * crond: reap orphaned grandchildren to prevent zombie buildupValentin Lab2025-07-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a cron job launches a background task, e.g. `sh -c "sleep 5 &"`, the shell exits immediately and the `sleep` process is re-parented to PID 1. When BusyBox `crond` itself happens to be PID 1 (common in a minimal container), those orphans become direct children of `crond`. Because `crond` only calls waitpid() for the PIDs it explicitly tracks, these processes remain forever in Z state and the container slowly fills with zombies. Add a small `while (waitpid(-1, NULL, WNOHANG) > 0)` sweep at the end of check_completions() so any stray children are reaped. When `crond` is not PID 1 the loop returns -ECHILD immediately, so behaviour and overhead on a normal system are unchanged.

* | make: fix detection of target rule with inline commandRon Yorston2025-01-221-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f9d10b2b6 (make: fix detection of target rules (take 2)) added code to handle the case where a target rule had an inline command with a ';' separator in a macro. This required all macros on the line to be expanded, including those in the inline command. The ';' should first be searched for in the original line (without any macro expansion) and only if that fails should macros be expanded. This matches the behaviour of GNU and Unix V7 make. BSD and Schily make don't handle the case where the ';' is in a macro. (pdpmake GitHub issue 73)
* | make: fix single-suffix inference rule regressionRon Yorston2025-01-211-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | Commit 85bbce87d (make: support GNU/BSD suffixes and inference rules) added code to handle inference rules with arbitrary suffixes. Unfortunately it failed to check for a single-suffix rule in the case where no known suffix was found. Add the necessary code and a test which would have caught the problem. Adds 48 bytes.

* | make: phony targets and double colon rulesRon Yorston2025-01-161-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 770bad1fe (make: disallow inference rules for phony targets) added the GNU/BSD make feature that inference rules aren't used for phony targets. Normally a double-colon rule without associated commands causes an inference rule search. If the target of the double-colon rule was phony no search was carried out and the rule failed. As a result of this perl failed to build (on Linux, I didn't try on Windows). When a double-colon rule has no commands and a phony target the prerequisites should be built and the rule should succeed. Adds 32 bytes. (pdpmake GitHub issue #70)
* | make: minor tweaksRon Yorston2025-01-161-32/+37
| | | | | | | | | | | | | | | | | | | | | | Move the code to remove the suffix from a target into a separate function. There's no need to test for non-NULL 'makefile' in newcmd(). Cosmetic changes. Saves 0-16 bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The specification of inference rules in POSIX implies that only suffixes starting with a period and containing no other periods are to be considered. In contrast, both GNU and BSD make allow suffixes to contain an arbitrary number of periods, or none at all. Allow this as an extension. Adds 640-816 bytes. (pdpmake GitHub issue 70)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | POSIX mentions some restrictions on whether rules may or may not have prerequisites or commands: - most special targets shouldn't have commnds; - inference/.DEFAULT rules shouldn't have prerequisites. Enforce these restrictions in POSIX mode. Generally, implementations are happy to accept prerequisites or commands even if they're subsequently ignored. Allow this as an extension. Adds 216-256 bytes.
* | make: changes to .DEFAULT/inference rulesRon Yorston2024-10-201-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The POSIX standard allows inference rules to be redefined but not the .DEFAULT rule. There is no explicit exception for .DEFAULT to: Only one target rule for any given target can contain commands. Treat redefinition of a .DEFAULT rule as an error in POSIX mode but allow it as an extension. Also, the code didn't allow an inference rule with dependencies to redefine an existing inference rule. This is no longer the case. Adds 64-96 bytes.
* | make: fix test for empty command in inference ruleRon Yorston2024-10-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Commit e90345c10 (make: allow empty commands) changed how empty commands are handled. This broke the POSIX mode test for inference rules of the form: rule: ; Adjust the setting of 'semicolon_cmd' to the new reality. Adds 16-32 bytes.
* | make: relax definition of comment lineRon Yorston2024-10-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | According to POSIX: Blank lines, empty lines, and lines with <number-sign> ('#') as the first character on the line are also known as comment lines. Most implementations also include lines where the first non-blank character is '#'. Allow this as an extension. Adds 0-16 bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running 'make thing.z' with the following makefile: .SUFFIXES: .x .y .z .x.y: cp $< $@ .y.x: cp $< $@ .y.z: cp $< $@ resulted in infinite recursion and a segfault.

* | make: look for PDPmakefileRon Yorston2024-10-171-10/+9
| | | | | | | | | | | | | | | | As an extension have pdpmake look for the file 'PDPmakefile' before 'makefile' and 'Makefile'. This is similar to how GNU make first checks for 'GNUmakefile'. Adds 32-40 bytes.
* | make: fix error reporting for included filesFRP-5467-g9376eebd8Ron Yorston2024-09-151-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | The global variables 'makefile' and 'lineno' weren't properly reset after a recursive call to input(). As a result error messages for included files could refer to the wrong file or line number. Restore 'makefile' and 'lineno' immediately after a rescursive call to input(). This also requires a different fix for commit b21546ddb (make: fix test for include with no pathnames). Adds 16 bytes in the 32-bit build.
* | make: fix test for include with no pathnamesRon Yorston2024-09-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In POSIX 2024 the behaviour of an include line with no pathnames is unspecified. The test for this condition was incorrect in certain circumstances. Files containing dependencies may be generated by the compiler and included in the makefile. On an initial build no dependency files will be present and the include line is made to ignore errors. In this case the test for no pathnames returned true, even though many pathnames may have been present. Fix the problem by always setting 'makefile' even if the named file can't be opened.
* | make: handling of leading whitespace in makefilesRon Yorston2024-09-101-14/+16

(Tested with GNU, BSD, Schily and UNIX Version 7 make.) - Commands in rules must start with a tab. It's the law. - BSD make doesn't allow any whitespace at the start of an include line. Enforce this restriction in POSIX mode: 'the word include ... appears at the beginning of a line'. As an extension allow arbitrary tabs or spaces. - All implementations allow a space as the first character of a macro definition or rule. Permit this in all cases. - Only GNU make allows a tab as the first character of a macro definition, but POSIX 2024 seems to permit it too: 'string1 is defined as all characters from the first non-<blank> character to the last non-<blank> character, inclusive'. Allow this in POSIX 2024 mode and as an extension. - No implementation allows a tab as the first character of a rule. Disallow this in all cases. Adds 32-64 bytes. (pdpmake GitHub issue 63)
* | make: reinstate conditional skipping of command linesRon Yorston2024-09-101-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit e90345c10 (make: allow empty commands) rearranged readline() in a way that broke the use of conditionals within the definition of a rule. Add a test case to detect this. Adjust readline() so that conditionals are processed before returning command lines or checking for empty lines and comments. Remove the test for a leading tab in skip_lines(). This allows conditionals in the definition of a rule to be indented with a leading tab.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f3f72ac1d (make: show location of errors during build) stored a pointer to the name of the makefile with each command, for use in diagnostic messages.

Omit the Windows include file that declares them. - Apply the hack for struct timeval in the 'ts' applet on 32-bit. Adds 1624 bytes on 32-bit, none on 64-bit. (GitHub issue #446)
* | make: disallow inference rules for phony targetsRon Yorston2024-08-101-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | GNU make doesn't allow inference rules or the .DEFAULT target to be used for phony targets.

* | make: allow empty commandsRon Yorston2024-08-081-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pdpmake didn't allow rules to have empty commands. There are circumstances where this may be useful. Make the following changes: - Add a flag to readline() to indicate the next line is expected to be a command. If this flag is true and the input line starts with a tab return it immediately, thus skipping the check for an empty line or comment line. - In docmds() skip tabs and spaces after a command prefix. If the resulting command is empty don't print it or try to execute it. - In newcmd() allow empty commands. Adds 48-96 bytes. (pdpmake GitHub issue 56)
