Christopher Faylor b4054e7706 * hookapi.cc: Add comment header
(putmem): Make static.
(get_export): Ditto.
(rvadelta): Ditto.  Don't assume that a section which ends where the import_rva
begins is the import list.
* child_info.h: Update copyright.
* fork.cc: Ditto.
2006-07-06 17:16:37 +00:00
Christopher Faylor 12b3371289 * dcrt0.cc (child_info_fork::handle_fork): Set uid/gid in myself so that it can
be used by subsequent startup functions.
(dll_crt0_0): Issue a warning if DuplicateTokenEx fails and DEBUGGING.
(dll_crt0_1): Move user_data->{resourcelocks,threadinterface} initialization
here from dll_crt0_0.
* fork.cc (frok::child): Tell wait_for_sigthread that this is fork.
(frok::parent): Only initialize start_time once.  Tighten time when we're
"deimpersonated".
* sigproc.cc (signal_fixup_after_exec): Rework (futiley) sa_buf stuff.  Add
debugging output.
(wait_for_sigthread): Accept an argument which illustrates whether we are
forked or not.
(wait_sig): Avoid using myself pointer.
* winsup.h ((wait_for_sigthread): Reflect change to argument.
2006-03-29 06:35:25 +00:00
Christopher Faylor 81010d21e6 * fhandler.cc (fcntl): Print flags in hex.
* dcrt0.cc (dll_crt0_0): Semi-revert 2006-03-14 change which moved pinfo_init
and uinfo_init here.
(dll_crt0_1): Ditto.
(__dll_crt0): Ditto.  Don't call update_envptrs here.
(dll_crt0_1): Ditto.  Move wait_for_sigthread call here from dll_crt0_0.
* environ.cc (environ_init): Call it here instead.
* sigproc.cc (my_readsig): New static variable.
(wait_for_sigthread): Set up read pipe here since we are assured that we have
the proper privileges when this is called.
(talktome): Eliminate second argument since it is available as a global now.
(wait_sig): Reflect use of my_readsig.
2006-03-22 16:42:45 +00:00
Christopher Faylor a939686807 * child_info.h (CURR_CHILD_INFO_MAGIC): Regenerate.

(child_info_fork::retry): Move to parent.
(child_info_fork::fork_retry): Ditto.
* dcrt0.cc (child_info::fork_retry): Rename and move.
(child_info_fork::handle_failure): Move.
(dll_crt0_0): Initialize console handler based on whether we have a controlling
tty or not.  Avoid nonsensical check for fork where it can never occur.
* environ.cc (set_proc_retry): Rename from set_fork_retry.  Set retry_count in
child_info.
(parse_thing): Reflect above change.
* exceptions.cc (dummy_ctrl_c_handler): Remove unused variable name.
(ctrl_c_handler): Always return TRUE for the annoying CTRL_LOGOFF_EVENT.
* fhandler_termios.cc (fhandler_termios::tcsetpgrp): Remove call to
init_console_handler.
* fhandler_tty.cc (fhandler_tty_slave::open): Just call mange_console_count
here and let it decide what to do with initializing console control handling.
* fork.cc (fork_retry): Remove definition.
(frok::parent): Define static errbuf and use in error messages (not thread safe
yet).  Close pi.hThread as soon as possible.  Protect pi.hProcess as soon as
possible.  Don't set retry_count.  That happens automatically in the
constructor now.  Accommodate name change from fork_retry to proc_retry.
* init.cc (dll_entry): Turn off ctrl-c handling early until we know how it is
supposed to be handled.
* pinfo.cc (_pinfo::dup_proc_pipe): Remember original proc pipe value for
failure error message.  Tweak debug message slightly.
* sigproc.cc (child_info::retry_count): Define.
(child_info::child_info): Initialize retry count.
(child_info::sync): Set exit code if process dies before synchronization.
(child_info::proc_retry): Rename from child_info_fork::fork_retry.  Use
previously derived exit code.  Be more defensive about what is classified as an
error exit.
(child_info_fork::handle_failure): Move here from dcrt0.cc.
* spawn.cc (spawn_guts): Maintain error mode when starting new process to avoid
annoying pop ups.  Move deimpersonate call within new loop.  Move envblock
freeing to end.  Loop if process dies prematurely with bad exit code.
* syscalls.cc (init_console_handler): Remove hopefully unneeded call to
init_console_handler.
