2020-10-18Fix cyclic dependecy detection and reporting.HEADmasterSergey Poznyakoff6
Use modified Floyd-Warshall algorithm for cyclic dependecy detection. The computed next vertex indices are used when reporting the cycles found. This fixes dead loops that occurred in earlier versions when trying to report cycles. One of inputs that caused such behavior is used as a new test in cyclic.at. * src/depmap.c: Rewrite using modified Floyd-Warshall algorithm. (depmap_cycle_detect,depmap_path_free): New functions. * src/comp.c (report_cyclic_dependency): Take struct depmap_path * as argument. (component_build_depmap): Use depmap_cycle_detect to detect cyclic dependencies. (depmap_dump): Special handling for zero-sized depmap. * tests/cyclic.at: Add new test. * src/pies.h (depmap_dim, depmap_free) (depmap_cycle_detect,depmap_path_free): New protos. * NEWS: Document changes.

2019-06-02New configuration statement for manipulating the environment.Sergey Poznyakoff16
The "env" statement is now a compound statement. It can contain four substatements: "clear" to clear the environment, "keep" to retain certain variable while clearing it, "set" to set a variable, and "unset" to unset a variable or variables. Both "keep" and "unset" can take globbing pattern as their argument, in which case they affect all variable matching that pattern. The value part in the "set" statement is subject to variable expansion, e.g. set "MANPATH=$MANPATH${MANPATH:+:}/usr/local/man" The support for the old one-line syntax of "env" is retained for backward compatibility. This commit also fixes redirection to a file: new data are appended to the file, instead of overwriting it. * lib/Makefile.am: Add new files. * lib/envop.c: New file. * lib/envop.h: New file. * lib/wildmatch.c: New file. * src/comp.c (component_free): Update. * src/pies.c (argv_free): New function. (parse_legacy_env): New function. (_cb_env): Remove. (cb_env_section_parser): New function. (cb_env_keywords): New keywords for the "env" block statement: clear, keep, set, unset. (component_keywords): New compount statement: env. Old usage retained for backward compatibility. * src/pies.h: Include "envop.h" (component)<env>: Remove. <envop>: New field. * src/prog.h (prog)<env>: New field. * src/progman.c (redirect_to_file): Position to the end of file. (DEBUG_ENVIRON): Remove macro. (debug_environ): New function. (environ_setup): Remove. (prog_sockenv): Use environ_set to modify local copy of environment. (prog_start_prologue): Use environ_create + envop_exec to create and modify the environment.

2019-05-31Minor fixSergey Poznyakoff1
* tests/shell.at: Append to the outfile instead of overwriting it.
2019-05-31Provide an option to run commands via sh -cSergey Poznyakoff10
The new flag "shell" instructs pies to run the command marked with it as '/bin/sh -c $command'. Alternative shell can be supplied ising the 'program' statement. This is useful if the command line uses shell-specific features (command or variable expansion, redirection, pipes, etc.) This commit also fixes a bug in the 'env' statement handling: a single argument with embedded whitespaces was undergoing word splitting and thus incorrectly handled as multiple arguments. * NEWS: Document changes. * doc/pies.texi: Likewise. * src/comp.c (component_free): Free command. (component_finish): Split command into argv/argc as directed by the CF_SHELL flag. * src/pies.c (_cb_command): Remove. Functionality moved to component_finish(). (_cb_env): Bugfix. Don't split arguments. * src/pies.h (CF_SHELL): New flag. (component) <command>: New member. * tests/Makefile.am: Add new tests. * tests/testsuite.at: Add new tests. * tests/aux/respawn: Change default timeout to 1 second. * tests/respawn.at: Minor change. * tests/shell.at: New test.

2019-05-24Initial implementation of "startup" components.Sergey Poznyakoff17
These are components that are run at program startup. Starting other components is delayed until all startup components terminate. This is similar to SysV "bootwait" components. Upon termination, startup components are removed from the configuration. They are not renewed upon configuratuion reload. * src/comp.c (comp_array_remove): Remove from the depmap as well. (component_ref_decr): Use comp_array_remove for active components and plain component_free for inactive ones. (component_build_depmap): Use comp_array_remove. (component_config_commit): Special handling for pies_comp_startup components. * src/pies.c (modetab): New component modes: "startup" and "shutdown". (main): Run program_init_startup. * src/pies.h (pies_comp_mode): New modes: pies_comp_startup and pies_comp_shutdown. (program_init_startup): New proto. * src/progman.c (progman_waiting_p): Return 1 if a startup component is still running. (program_init_startup): New function. (progman_cleanup): Handle pies_comp_startup termination. * src/socket.c (switch_eids): Avoid unnecessary calls to setegid and seteuid. * tests/atlocal.in (auxdir): New variable. * tests/mailer: Move to tests/aux/ * tests/respawn: Move to tests/aux/ * tests/retcode: Move to tests/aux/ * tests/aux/startup: New auxiliary program. * tests/redirect.at: Start components from $auxdir. * tests/respawn.at: Likewise. * tests/ret-exec.at: Likewise. * tests/ret-notify.at: Likewise. * tests/startup.at: New file. * tests/testsuite.at: Include startup.at * tests/Makefile.am: Add new tests.
