new flexibility, specifically the 'root' option. Now, we just use
"install" to do a fake installation into a temporary directory
(the 'bdist_dir' option, which derives from the 'bdist_base' option of
"bdist"), and then tar/zip up that directory. This means that dumb
built distributions are now relative to the root directory, rather than
the prefix or exec-prefix; this is probably a feature, but does make
them slightly less flexible.
top-level temporary directory for creating built distributions. (Won't
work yet, since the "build" command doesn't yet have a 'build_bdist'
option, and none of the "bdist" commands support it yet.)
- renamed '_copydata()' to 'copy_files()'
- changed it to record complete output filenames
- dropped '_outputdata()' in favour of much simpler 'get_outputs()'
adds the 'install_data' and 'install_scripts' commands; these two
are trivial thanks to the 'install_misc' base class in cmd.py.
(Minor tweaks and commentary by me; the code is untested so far.)
Also added creation of 'implib_dir', a temporary directory specific to
MSVC++ -- but I checked in two ways of fixing it (Lyle's and mine),
because I'm not sure which is right.
even if it's already absolute. Currently only implemented for Unix; I'm
not entirely sure of the right thing to do for DOS/Windows, and have no
clue what to do for Mac OS.
in command-line options, and in two phases at that: first, we expand
'install_base' and 'install_platbase', and then the other 'install_*'
options. This lets us do tricky stuff like
install --prefix='/tmp$sys_prefix'
...oooh, neat.
Simplified 'select_scheme()' -- it's no longer responsible for expanding
config vars, tildes, etc.
Define installation-specific config vars in 'self.config_vars', rather than
in a local dictionary of one method. Also factored '_expand_attrs()' out
of 'expand_dirs()' and added 'expand_basedirs()'.
Added a bunch of debugging output so I (and others) can judge the
success of this crazy scheme through direct feedback.
Adds bztar format to generate .tar.bz2 tarballs
Uses the -f argument to overright old tarballs automatically, I am
assuming that if the old tarball was wanted it would have been moved or
else the version number would have been changed.
Uses the -9 argument to bzip2 and gzip to use maximum
compression. Compress uses the maximum compression by default.
Tests for correct value for the 'compress' argument of make_tarball. This
is one less place for someone adding new compression programs to forget to
change.
to add the "display metadata" options: --name, --version, --author,
and so forth. Main changes:
* added 'display_options' class attribute to list all the "display only"
options (--help-commands plus the metadata options)
* added DistributionMetadata class as a place to put the actual
metadata information from the setup script (not to be confused with
the metadata display options); the logic dealing with metadata
(eg. return self.name or "UNKNOWN") is now in this class
* changed 'parse_command_line()' to use the new OO interface provided
by fancy_getopt, mainly so we can get at the original order of
options on the command line, so we can print multiple lines of
distribution meta-data in the order specified by the user
* added 'handle_display_options()' to handle display-only options
Also fixed some crufty old comments/docstrings.
class. (Mainly this was to support the ability to go back after the
getopt operation is done and get extra information about the parse,
in particular the original order of options seen on the command line.
But it's a big improvement and should make it a lot easier to add
functionality in the future.)
- DistutilsOptionError is now documented as it's actually used, ie.
to indicate bogus option values (usually user options, eg. from
the command-line)
- added DistutilsSetupError to indicate errors that definitely arise
in the setup script
- got rid of DistutilsValueError, and changed all usage of it to
either DistutilsSetupError or ValueError as appropriate
- simplified a bunch of option get/set methods in Command and
Distribution classes -- just pass on AttributeError most of
the time, rather than turning it into something else
than we actually use, and do actually use AR and SO.
Run ranlib on static libraries. (Should probably have a platform-check
so we don't run ranlib when it's not necessary, ie. on most modern
Unices.)
crashing when self.force not defined.
Revise 'copy_file()' and 'copy_tree()' docstrings accordingly.
Remove 'hasattr()' check for 'self.force' from 'make_file()'.
to all commands in the same way. Several Command methods now either expect
'self.force' to be defined, or check if it is defined and assume it's
false if not.
Added code to include source files from 'build_clib' command to default file
list -- currently this won't work, since 'build_clib' doesn't have a
'get_source_files()' method!
- file_util.py: operations on single files
- dir_util.py: operations on whole directories or directory trees
- dep_util.py: simple timestamp-based dependency analysis
- archive_util.py: creation of archive (tar, zip, ...) files
The functions left in util.py are miscellany that don't fit in any of the
new files.
the Command class from core.py to cmd.py. No other code needs changing
though; distutils.core still provides the Command and Distribution classes,
although indirectly now.
HKEY_* and Reg* names once, rather than having near-duplicate code
in the two import attempts.
Also dropped the leading underscore on all the imported symbols,
as it's not appropriate (they're not local to this module).
* build to "Debug" or "Release" temp directory
* put linker turds (.lib and .exp files) in the build temp directory
* tack on "_d" to extensions built with debugging
* added 'get_ext_libname()' help in putting linker turds to temp dir
Also, moved the code that simplifies None to empty list for a bunch
of options to 'finalize_options()' instead of 'run()'.
Simplified 'Command.get_peer_option()' a tad -- just call 'find_peer()'
to get the peer command object.
Updated 'Command.copy_file()' to take a 'link' parameter, just like
'util.copy_file()' does now.
Added 'Command.make_archive()' to wrap 'util.make_archive()'.
Changes to 'copy_file()':
* added support for making hard links and symlinks
* noted that it silently clobbers existing files when copying, but
blows up if destination exists when linking -- hmmm...
* error message tweak
Added 'base_name' parameter to 'make_tarball()' and 'make_zipfile()'.
Added 'make_archive()' -- wrapper around 'make_tarball()' or
'make_zipfile()' to take care of the archive "root directory".
the command that actually creates "dumb" binary distributions, ie.
tarballs and zip files that you just unpack under <prefix> or <exec-prefix>.
Very limited, but it's a start.
Initial revision is pretty limited; it only knows how to generate "dumb"
binary distributions, i.e. a tarball on Unix and a zip file on Windows.
Also, due to limitations in the installation code, it only knows how to
distribute Python library code. But hey, it's a start.
provided by Distribution.
Cosmetic and error message tweaks.
Simplified 'make_release_tree()':
* extracted 'distutils.util.create_tree()'
* don't have to do hard-linking ourselves -- it's now handled by
'distutils.util.copy_file()' (although the detection of
whether hard linking is available still needs to be factored out)
Removed 'make_tarball()' and 'make_zipfile()' entirely -- their role
is now amply filled by 'distutils.util.make_archive()'.
Simplified 'make_distribution()':
* use Distribution's new 'get_full_name()' method
* use 'make_archive()' instead of if/elif/.../else on the archive format
is responsible for installing all Python modules (pure and extensions).
Added 'get_outputs()' in preparation for the 'bdist' command, and
'_mutate_outputs()' to support 'get_outputs()'.
in a class attribute 'sub_commands', rather than hard-coded in 'run()'.
This should make it easier to subclass 'install', and also makes it
easier to keep 'run()' and the new 'get_outputs()' consistent.
Added 'get_outputs()' in preparation for the 'bdist' command.
Changed signature of 'build_extensions()': no longer takes the extension
list, but uses 'self.extensions' (just like 'get_outputs()' has to)
Moved call to 'check_extensions_list()' from 'run()' to 'build_extensions()',
again for consistency with 'get_outputs()'.
A host of improvements in preparation for the 'bdist' command:
- added 'get_outputs()' method (all the other improvements were to support
this addition)
- made 'find_package_modules()' and 'find_modules()' return similar
values (list of (package, module, module_filename) tuples)
- factored 'find_all_modules()' out of 'get_source_files()' (needed
by 'get_outputs()')
- factored 'get_module_outfile()' out of 'build_module()' (also needed
by 'get_outputs()')
- various little tweaks, improvements, comment/doc updates
we don't know what to do with it when we see it.
Call '_fix_object_args()' and/or '_fix_lib_args()' as appropriate, rather
than just '_fix_link_args()'.
Split '_fix_link_args()' up into '_fix_object_args()' (for use of
'create_static_lib() and link methods) and '_fix_lib_args()' (for the
link methods only).
these must come from the 'build' command. This means we no longer need
the misconceived 'set_peer_option()' method in Command and, more importantly,
sweeps away a bunch of potential future complexity to handle this tricky
case.
Fix 'Command.set_undefined_option()' to call 'ensure_ready()' rather
than 'finalize_options()' (which is only supposed to be called once,
which is the whole point of 'ensure_ready()').
Added comment to 'set_peer_option()' to remind myself that this method
cannot work and is fundamentally wrong-headed.
this command for a while; this implements roughly the plan cooked up by
Guido, Fred, and me. Seems to strike a nice balance between usability in
the common cases (just set one option), expandability for more types of
files to install in future, and customizability of installation
directories.
This revision isn't completely working: standard and alternate
installations work fine, but there are still some kinks to work out of
customized installations.
* improve help strings
* warn if user supplies non-existing directories
* don't try to 'remove_tree()' non-existing directories
* try to remove the build_base after cleanup (but don't do or say
anything if it fails -- this is just in case we made it empty)
option in the 'build_ext' command):
* in ccompiler.py: 'gen_lib_options()' now takes 'runtime_library_dirs'
parameter
* in unixccompiler.py and msvccompiler.py: now pass
'self.runtime_library_dirs' to 'gen_lib_options()', and define
'runtime_library_dir_option()' (although in msvccompiler.py it
blows up with a DistutilsPlatformError right now!)
sure it's imported! ;)
Re-wrap the docstrings on get_python_inc() and get_python_lib() to be
closer to the "normal" Python style. See GvR's "style guide" on the
essays page (http://www.python.org/doc/essays/).
There should never be a space between a function name and the '(' that
opens the argument list (see the style guide again).
the platform-neutral include dir by default and with Mac support.
Added 'get_python_lib()', inspired by 'get_python_inc()'.
Rewrote 'get_config_h_filename()' and 'get_makefile_filename()'
in terms of 'get_python_inc()' and 'get_python_lib()'.
Changed '_init_nt()' and '_init_mac()' to use 'get_python_inc()' and
'get_python_lib()' for directory names.
implement it (so far):
* moved filename generation methods into CCompiler base class,
driven by data supplied by implementation classes
* moved a bunch of common code from UnixCCompiler to convenience
methods in CCompiler
* overhauled MSVCCompiler's compile/link methods to look and act
as much as possible like UnixCCompiler's, in order to regularize
both interface and behaviour (especially by using those new
convenience methods)
* replaced build_lib.py with build_clib.py
* renamed the class in build_clib.py
* changed all references to 'build_lib' command in other command classes
when building extensions (uses build_lib's 'get_library_names()' method).
Ensure that the relative structure of source filenames is preserved in
the temporary build tree, eg. foo/bar.c compiles to
build/temp.<plat>/foo/bar.o.
Added 'build_clib' and 'build_temp' options (where to put C libraries
and where to put temporary compiler by-products, ie. object files).
Moved the call to 'check_library_list()' from 'run()' to 'finalize_options()'
-- that way, if we're going to crash we do so earlier, and we guarantee
that the library list is valid before we do anything (not just run).
Disallow directory separators in library names -- the compiled library
always goes right in 'build_clib'.
Added 'get_library_names()', so the "build_ext" command knows what
libraries to link every extension with.
filenames when constructing object filenames, even if output_dir given --
eg. "foo/bar.c" will compile to "foo/bar.o" without an output_dir, and to
"temp/foo/bar.o" if output_dir is "temp".
* 'build_dir' -> 'build_lib', which by default takes its value
straight from 'build_lib' in the 'build' command
* added 'build_temp' and 'inplace' options
* change 'build_extensions()' to put object files (compiler turds) in
'build_temp' dir
* complicated the name-of-extension-file shenanigans in
'build_extensions()' to support "in-place" extension building, i.e.
put the extension right into the source tree (handy for developers)
* added 'get_ext_fullname()', renamed 'extension_filename()' to
'get_ext_filename()', and tweaked the latter a bit -- all to support
the new filename shenanigans
old 'dist' command, but the code for dealing with manifests is completely
redone -- and renaming the command to 'sdist' is more symmetric with the
soon-to-exist 'bdist' command.
'get_msvc_paths()'.
Renamed '_do_SET()' to 'set_path_env_var()', tweaked docstring, and
cosmetically tweaked code.
Stylistic changes to MSVCCompiler constructor (variable renaming
and type consistency).
* tweak my docstrings
* fix None returns to empty list
* reshuffle responsibilities between '_find_exe()', '_find_SET()', and
the MSVCCompiler constructor -- now the constructor worries about
fetching the version list and determining the most recent one
* added "/W3" compile option
Also, I added/tweaked some docstrings.
* don't need to mention python<ver>.lib -- it's done by a pragma
* add debug flags for compile and link, and use them
* fix 'link_shared_library()' to pass everything to 'link_shared_object()'
* change filename when shared object with debug info (ugh)
someone who knows Windows/MSVC++ to come along and add the right flags.
Comment noting that 'link_static_lib()' signature is inconsistent with
the other compiler classes (uh-oh!)
'--help-commands' option).
Shuffled imports around in a few command modules to avoid expensive
up-front import of sysconfig (and resulting delays in generating list
of all commands).
* "--help" can now come either before or after particular commands
to get help on and can give help on multiple commands, eg.
"--help install dist" gives help on those two commands
* added "--help-commands" option, implemented by the 'print_commands()'
and 'print_command_list()' methods
Added 'link_static_lib()' method, and 'archiver' and 'archiver_options'
class attributes to support it.
Added 'link_executable()' method, and 'ld_exec' instance attribute
to support it.
'newer_group()' is now able to handle missing files, so we don't have
to kludge it by catching OSError when calling it.
'object_filenames()' and 'shared_object_filename()' now take 'keep_dir'
flag parameters.
'library_filename()' and 'shared_library_filename()' now respect
a directory component in the library name.
Various comment updates/deletions.
Added 'nuke_release_tree()' method to blow away the directory from
which the archive file(s) are created, and call it (conditionally)
from 'make_distribution()'.
Added 'keep_tree' option (false by default) to disable the call to
'nuke_release_tree()'.
install) the setup script itself.
Fixed 'build_module()' so we do *not* preserve file mode (which means
we can install read-only files, which makes the next installation
of this distribution fail -- at least under Unix); added a comment
explaining this.
consistency with 'build_ext' command option.
Changed 'compile()' and 'link_shared_object()' so 'include_dirs',
'libraries', and 'library_dirs' can be lists or tuples.
'generate_help()', 'wrap_text()' functions, and a little tiny test
of 'wrap_text()'.
Changed how caller states that one option is the boolean opposite of
another: added 'negative_opt' parameter to 'fancy_getopt()', and changed
to use it instead of parsing long option name.
want no output. Still no option for a happy medium though.
Added "--help" global option.
Changed 'parse_command_line()' to recognize help options (both for the
whole distribution and per-command), and to distinguish "regular run"
and "user asked for help" by returning false in the latter case.
Also in 'parse_command_line()', detect invalid command name on command
line by catching DistutilsModuleError.
a 'negative_opt' class attribute right after 'global_options'; changed
how we call 'fancy_getopt()' accordingly.
Initialize 'maintainer' and 'maintainer_email' attributes to Distribution
to avoid AttributeError when 'author' and 'author_email' not defined.
Initialize 'help' attribute in Command constructor (to avoid
AttributeError when user *doesn't* ask for help).
In 'setup()':
* show usage message before dying when we catch DistutilsArgError
* only run commands if 'parse_command_line()' returned true (that
way, we exit immediately when a help option is found)
* catch KeyboardInterrupt and IOError from running commands
Bulked up usage message to show --help options.
Comment, docstring, and error message tweaks.
Bunch of little bug fixes that appeared in building non-packagized
distributions. Mainly:
- brain-slip typo in 'get_package_dir()'
- don't try to os.path.join() an empty path tuple -- it doesn't like it
- more type-safety in 'build_module()'
Now supports the full range of intended formats (tar, ztar, gztar, zip).
"-f" no longer a short option for "--formats" -- conflicts with new
global option "--force"!
global options table.
Every Command instance now has its own copies of the global options,
which automatically fallback to the Distribution instance. Changes:
- initialize them in constructor
- added '__getattr__()' to handle the fallback logic
- changed every 'self.distribution.{verbose,dry_run}' in Command to
'self.{verbose,dry_run}'.
- filesystem utility methods ('copy_file()' et al) don't take 'update'
parameter anymore -- instead we pass 'not force' to the underlying
function as 'update'
Changed parsing of command line so that global options apply to all
commands as well -- that's how (eg.) Command.verbose will be initialized.
Simplified 'make_file()' to use 'newer_group()' (from util module).
Deleted some cruft.
Some docstring tweaks.
the code a bit and should make it work under Windows even with trailing
backslash.
Fixed a couple of docstrings.
Added comment about 'make_file()' possibly being redundant and unnecessary.
- change how we call it
- added methods 'library_dir_option()', 'library_option()', and
'find_library_file()' that it calls
Added 'force' flag; it's automatically "respected", because this class
always rebuilds everything! (Which it to say, "force=0" is not respected.)
Catch up with changes in 'gen_lib_options()':
- change how we call it
- added methods 'library_dir_option()', 'library_option()', and
'find_library_file()' that it calls
Added 'force' flag and changed compile/link methods to respect it.
has a directory component, then we only search for the library in
that one directory, ie. ignore the 'library_dirs' lists for that
one library.
Changed calling convention to 'gen_lib_options()' again: now, it takes
a CCompiler instance and calls methods on it instead of taking
format strings. Also implemented the new "library name" semantics
using the 'find_library_file()' method in the CCompiler instance.
Added 'force' flag to CCompiler; added to constructor and 'new_compiler()'.
Added 'warn()' method.
Catch up with renamed 'platdir' -> 'build_platlib' option in 'build'.
Don't call 'set_final_options()' in 'run()' anymore -- that's now
guaranteed to be taken care of for us by the Distribution instance.
If 'include_dirs' is a string, split it on os.pathsep (this is half-
hearted -- support for setting compile/link options on the command
line is totally lame and probably won't work at all).
Added 'get_source_files()' for use by 'dist' command.
Added code to 'build_extensions()' to figure out the "def file" to use
with MSVC++ and add it to the linker command line as an "extra_postarg".
Don't call 'set_final_options()' in 'run()' anymore -- that's now
guaranteed to be taken care of for us by the Distribution instance.
Rearranged to bit to allow outsiders (specifically, the 'dist' command)
to find out what modules we would build:
- 'find_modules()' renamed to 'find_package_modules()'
- most of 'build_modules()' abstracted out to 'find_modules()'
- added 'get_source_files()' (for the 'dist' command to use)
- drastically simplified 'build_modules()' -- now just a wrapper around
'find_modules()' and 'build_module()'
Tweaked some help strings to be consistent with documentation.
Don't call 'set_final_options()' in 'run()' anymore -- that's now
guaranteed to be taken care of for us by the Distribution instance.
- add 'extra_preargs' and 'extra_postargs' parameters (and use them!)
- got rid of 'build_info' kludge parameter
- added 'compiler_type' class attribute
- respect reordered arguments to 'gen_lib_options()'
Also added 'output_dir' parameter (catching up with older change in
CCompiler) -- BUT this is presently ignored by all methods!
Deleted some more docstrings redundant with CCompiler.
Dropped generated of "/DEF:" argument --- that's now done by
the 'build_ext' command.
- add 'extra_preargs' and 'extra_postargs' parameters (and use them!)
- added 'compiler_type' class attribute
- respect reordered arguments to 'gen_lib_options()'
which allowed us to get rid of the 'build_info' used in some places
(a temporary kludge to support MSVC++ "def" files).
Deleted big comment whining about that kludge.
Added 'compiler_type' class attribute.
Overhauled 'new_compiler()': now takes 'compiler' argument along with
'plat' (both optional with sensible defaults), and looks them both up
in the new 'default_compiler' and 'compiler_class' dictionaries to
figure out where to get the concrete compiler class from.
Reordered arguments to 'gen_lib_options()' to match the order in
which the arguments are generated (ie. -L before -l).
they make sure that 'set_final_options()' has been called, but isn't
called redundantly.
Changed Distribution to call 'ensure_ready()' where it used to call
'set_final_options()', and in a few extra places as well.
Lots of comment/docstring revisions and additions in both classes.
New one-liner utility methods in Command: 'find_peer()', 'spawn()'.
'alias_options' table and getting rid of some hairy code in the
Distribution constructor.
Resurrected the distribution options that describe the modules present
in the module distribution ('py_modules', 'ext_modules'), and added
a bunch more: 'packages', 'package_dir', 'ext_package', 'include_dirs',
'install_path'.
Updated some comments.
Added 'warn()' method to Command.
'Command.get_command_name()' now stores generated command name in
self.command_name.
Added global cache PATH_CREATED used by 'mkpath()' to ensure it doesn't
try to create the same path more than once in a session (and, more
importantly, to ensure that it doesn't print "creating X" more than
once for each X per session!).
distributions their own directory (and .pth file).
Overhauled how we determine installation directories in
'set_final_options()' to separate platform-dependence and take
'install_path' option into account.
Added 'create_path_file()' to create path config file when 'install_path'
given.
Only run 'install_py' and 'install_ext' when, respectively, there are
some pure Python modules and some extension modules in the distribution.
- rename 'dir' to 'build_dir'
- take 'package' from distribution option 'ext_package'
- take 'extensions' from distribution option 'ext_modules'
- take 'include_dirs' from distribution
Name keyword args explictly when calling CCompiler methods.
Overhauled how we generate extension filenames (in 'extension_filename()
and 'build_extension()') to take 'package' option into account.
Changed those two methods to only compile/link if necessary (according
to simplistic timestamp checks).
Added 'output_dir' to 'object_filenames()' and 'shared_object_filename()'.
attributes, etc. Biggest change was to the Distribution constructor
-- it now looks for an 'options' attribute, which contains values
(options) that are explicitly farmed out to the commands. Also,
certain options supplied to Distribution (ie. in the 'setup()' call in
setup.py) are now "command option aliases", meaning they are dropped
right into a certain command rather than being distribution options.
This is handled by a new Distribution class attribute,
'alias_options'.
Various comment changes to reflect the new way-of-thinking.
Added 'get_command_name()' method to Command -- was assuming its
existence all along as 'command_name()', so changed the code that
needs it to call 'get_command_name()'.
now provided (minus the leading underscore) by the ccompiler module.
Fix 'compile()' to return the list of object files generated.
Cosmetic tweaks/delete cruft.
Added big comment about the kludginess of passing 'build_options'
to the link methods and how to fix it.
Added 'gen_preprocess_options()' and 'gen_lib_options()' convenience
functions -- the two cases are very similar for Unix C Compilers and
VC++, so I figured I might as well unify the implementations.
- fix some broken abstract methods
- kludge: add 'build_info' parameter to link methods
- add 'object_name()' and 'shared_library_name()'
- support for MSVCCompiler class on NT/Win95
Added 'verbose' and 'dry_run' parameters to constructor.
Changed 'compile()', 'link_*()' to default lists arguments to None
rather than empty list.
Added implementations of the filename-mangling methods mandated by
the CCompiler interface.
'new_compiler()' factory function.
Added 'runtime_library_dirs' list (for -R linker option) and methods
to manipulate it.
Deleted some obsolete comments.
Added all the filename manglign methods: 'object_filenames()',
'shared_object_filename()', 'library_filename()',
'shared_library_filename()'.
Added 'spawn()' method (front end to the "real" spawn).
- did away with 'comment_re' option -- it's just not that simple anymore
- heavily revised the main logic in 'readline()' to accomodate this
Beefed up 'warn()': 'line' can be list or tuple, and 'msg' is
automatically converted to a string.
'install_site_lib' and install_site_platlib' on non-POSIX platforms.
Should at least work for NT, as this is adopted from Amos Latteier's NT
patches. Also added extensive comments bitching about the inadequacy of
the current model, both under POSIX and NT (and probably other) systems.
'run_command()' to refer to it before attempting to run a command --
that way, command classes can freely invoke other commands without fear
of duplicate execution.
Beefed up some comments and docstrings.
meaningful return values: respectively, whether the copy was done, and
the list of files that were copied. This meant some trivial changes in
core.py as well: the Command methods that mirror 'copy_file()' and
'copy_tree()' have to pass on their return values.
of the 'install_py' command rather than 'build_py'. Obviously, this
meant that the 'build_py' and 'install_py' modules had to change; less
obviously, so did 'install' and 'build', since these higher-level
commands must make options available to control the lower-level
commands, and some compilation-related options had to migrate with the
code.
and dry-run flags consistently painless): 'execute()', 'mkpath()',
'copy_file()', 'copy_tree()', 'make_file()', and stub for 'make_files()'
(not sure yet if it's useful).
that wrap them in the Command class).
Fixed 'copy_file()' to use '_copy_file_contents()', not 'copyfile()'
from shutil module -- no reference to shutil anymore.
Added "not copying" announcement in 'copy_file()'.
Wee comment fix.
