From 831d6fa520ed43d055924607a2d9be7fcc3813e9 Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Wed, 30 Oct 2002 21:05:18 +0000 Subject: * external.cc (cygwin_internal): Implement CW_CMDLINE. * pinfo.h (SIGCOMMUNE): New signal type. (commune_result): New structure for commune functions. (picom): New enum for commune functions. (_pinfo::hello_pid): New. Pid who's communicating with me. (_pinfo::tothem): New. Handle of communicating pipe. (_pinfo::fromthem): Ditto. (_pinfo::commune_recv): Declare. (_pinfo::commune_send): Declare. (_pinfo::alive): Declare. (_pinfo::cmdline): Declare. (_pinfo::lock): Declare. * pinfo.cc (set_myself): Initialize new _pinfo lock. (_pinfo::alive): Define. Determines if process still exists. (_pinfo::commune_recv): Define. Receive info from another cooperating process. (_pinfo::commune_send): Define. Send info to another cooperating process. (_pinfo::cmdline): Define. Determine command line of a given process. * include/sys/cygwin.h (CW_CMDLINE): Define. *sigproc.cc (talktome): Communicate with any processes who want to talk to me. (wait_sig): Honor __SIGCOMMUNE. * fhandler.cc (fhandler_virtual::fixup_after_exec): Declare. * fhandler_proc.cc: Use malloc/free/realloc throughout rather than cmalloc since buffers don't need to be propagated to subprocesses. * fhandler_registry.cc: Ditto. * fhandler_virtual.cc: Ditto. (fhandler_virtual::fixup_after_exec): Define. * fhandler_process.cc: Ditto for malloc/free/realloc. (process_listin): Add "cmdline". (fhandler_process::fill_filebuf): Implement PROCESS_CMDLINE. * miscfuncs.cc (isalpha_array): New array populated with xor values for alpha characters to switch from one case to another. * string.h (cygwin_strcasematch): New asm implementation of case match. * string.h (cygwin_nstrcasematch): New asm implementation of counted case match. --- winsup/cygwin/fhandler_virtual.cc | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-) (limited to 'winsup/cygwin/fhandler_virtual.cc') diff --git a/winsup/cygwin/fhandler_virtual.cc b/winsup/cygwin/fhandler_virtual.cc index 05b9b0f6c..937caf352 100644 --- a/winsup/cygwin/fhandler_virtual.cc +++ b/winsup/cygwin/fhandler_virtual.cc @@ -34,10 +34,17 @@ fhandler_virtual::fhandler_virtual (DWORD devtype): fhandler_virtual::~fhandler_virtual () { if (filebuf) - cfree (filebuf); + free (filebuf); filebuf = NULL; } +void +fhandler_virtual::fixup_after_exec (HANDLE) +{ + if (filebuf) + filebuf = NULL; +} + DIR * fhandler_virtual::opendir (path_conv& pc) { @@ -143,7 +150,7 @@ fhandler_virtual::dup (fhandler_base * child) if (!ret) { fhandler_virtual *fhproc_child = (fhandler_virtual *) child; - fhproc_child->filebuf = (char *) cmalloc (HEAP_BUF, filesize); + fhproc_child->filebuf = (char *) malloc (filesize); fhproc_child->bufalloc = fhproc_child->filesize = filesize; fhproc_child->position = position; memcpy (fhproc_child->filebuf, filebuf, filesize); @@ -156,7 +163,7 @@ int fhandler_virtual::close () { if (filebuf) - cfree (filebuf); + free (filebuf); filebuf = NULL; bufalloc = (size_t) -1; cygwin_shared->delqueue.process_queue (); -- cgit v1.2.3
