* how-fhandlers-work.txt: New file.
2001-10-02 12:27:03 +00:00
Christopher Faylor 4ab6034f50 * dtable.h (dtable::build_fhandler): Make path_conv parameter non-optional.
(dtable::init_std_file_from_handle): Eliminate name parameter.
* dtable.cc (stdio_init): Don't pass bogus name to init_std_file_from_handle.
The function will figure out the name itself.
(dtable::init_std_file_from_handle): Eliminate name parameter.  Assume that
we're always called with an appropriate fd.  Pass name as NULL if we can't
simply figure it out from context.
(cygwin_attach_handle_to_fd): Pass path_conv argument to build_fhandler.
(dtable::build_fhandler): Make path_conv argument mandatory.  Eliminate
specific call to get_device_number.  With unknown device names, set name from
handle context for parsing by path_conv.
(dtable::build_fhandler): Pass path_conv argument to build_fhandler.
* path.h (path_conv::set_isdisk): Set disk device type.
(path_conv::is_device): Don't consider FH_DISK a "device".
* syscalls.cc (_open): Pass path_conv argument by reference.
(stat_worker): Ditto.
(_rename): Use path_conv operators.  Add bounds to DeleteFile/MoveFile for
loop.

Christopher Faylor 47af76d8c8 * cygwin.din: export strtoll and strtoull 2001-10-01 19:47:37 +00:00
Christopher Faylor 47063f00e4 Add "path.h" include throughout, where needed. Use new path_conv methods and
operators to simplify testing for directory and attributes, throughout.
* path.h (path_conv::exists): New method.
(path_conv::has_attribute): Ditto.
(path_conv::isdir): Ditto.
(path_conv::DWORD &): New operator.
(path_conv::int &): Ditto.
* dir.cc (rmdir): Eliminate a goto.
* dtable.cc (dtable::build_fhandler): Accept opt and suffix info for
path_conv.check.  Return fh == NULL on path_conv error.  Pass unit to set_name
as appropriate.
(dtable::reset_unix_path_name): New method.
* dtable.h (dtable): Declare new method.  Reflect arg changes to
build_fhandler.
* fhandler.cc (fhandler_disk_dummy_name): Eliminate.
(fhandler_base::set_name): Expect paths to be NULL.  Build unix_path_name from
win32_path_name when it is a device.
(fhandler_base::reset_unix_path_name): New method.
(fhandler_base::raw_read): Report EISDIR when ERROR_INVALID_FUNCTION or
ERROR_INVALID_PARAMETER and reading a directory.
(fhandler_disk_file::fstat): Don't call stat_dev since we should now never be
calling fhandler_disk_file methods with devices.
(fhandler_base::fhandler_base): Clear {unix,win32}_path_name.
(fhandler_base::~fhandler_base): Always free {unix,win32}_path_name.
(fhandler_disk_file::fhandler_disk_file): Remove set_no_free_names kludge.

* fhandler_tty.cc (fhandler_tty_slave::fhandler_tty_slave): Don't set
unix_path_name here.
* path.cc (fchdir): Lock fd table throughout.  Use new
dtable::reset_unix_path_name method to reset path.
* syscalls.cc (stat_worker): Reorganize to always call fstat method.  Pass
path_conv method to fhandler_*::open.
(chroot): Elminate a goto.
2001-10-01 04:10:07 +00:00
Christopher Faylor c25c4c5ffc * environ.cc (winenv): Allocate exact amount of space needed for forced windows
environment variable rather than just using MAX_PATH.
2001-09-30 21:37:53 +00:00
Christopher Faylor bb6c3d5832 * Makefile.in: Depend on stamp to ensure rebuilding. Remove stamp file when
we've just built the DLL.
