OK.
It looks like Tcl has [file link -sybolic a b]. Will this not replace
ns_symlink? No truncate though, that sucks. TclX has ftruncate...
It has [file link symbolic] but is incompatible with what
ns_symlink is doing. Look:
lexxsrv:nscp 2> file mkdir /tmp/foo
lexxsrv:nscp 3> cd /tmp/foo
lexxsrv:nscp 4> exec touch bar
lexxsrv:nscp 5> ns_symlink bar barlink
lexxsrv:nscp 6> file link -symbolic tcllink bar
bar
lexxsrv:nscp 7> exec ls -l
-rw-rw-rw- 1 root wheel 0 Oct 5 09:40 bar
lrwxrwxrwx 1 root wheel 3 Oct 5 09:40 barlink -> bar
lrwxrwxrwx 1 root wheel 20 Oct 5 09:42 tcllink -> /private/tmp/
foo/bar
You see? Thats why I wrote (tcl/compat.tcl):
#
# ns_symlink --
#
# This is still implement in the server code. The reason is that
# the Tcl [file link] command always creates link target with
# absolute path to the linked file; nsd/tclfile.c:NsTclSymlinkObjCmd()
#
ns_symlink? No truncate though, that sucks. TclX has ftruncate...
Well, not only truncate, but:
#
# ns_truncate --
#
# This is still implement in the server code. The reason is that
# the Tcl has no portable equivalent; nsd/
tclfile.c:NsTclFTruncateObjCmd()
#
#
# ns_ftruncate --
#
# This is still implement in the server code. The reason is that
# the Tcl has no portable equivalent; nsd/
tclfile.c:NsTclTruncateObjCmd()
#
#
# ns_mktemp --
#
# This is still implement in the server code. The reason is that
# the Tcl has no portable equivalent; nsd/
tclfile.c:NsTclMkTempObjCmd()
#
#
# ns_tempnam --
#
# This is still implement in the server code. The reason is that
# the Tcl has no portable equivalent; nsd/
tclfile.c:NsTclTempNamObjCmd()
#
I will now checkin the nslog. Then I will tag before-tcl-vfs
and then checking the VFS changes. At the moment the VFS changes
mean: no direct OS calls related to file-operations. All (most)
is done using Tcl wrappers. Exceptions are: temporary filenames,
pipes and sockets.
