DESCRIPTION
    "File::Temp" can be used to create and open temporary files in a safe
    way. There is both a function interface and an object-oriented
    interface. The File::Temp constructor or the tempfile() function can be
    used to return the name and the open filehandle of a temporary file. The
    tempdir() function can be used to create a temporary directory.

    The security aspect of temporary file creation is emphasized such that a
    filehandle and filename are returned together. This helps guarantee that
    a race condition can not occur where the temporary file is created by
    another process between checking for the existence of the file and its
    opening. Additional security levels are provided to check, for example,
    that the sticky bit is set on world writable directories. See
    "safe_level" for more information.

    For compatibility with popular C library functions, Perl implementations
    of the mkstemp() family of functions are provided. These are, mkstemp(),
    mkstemps(), mkdtemp() and mktemp().

    Additionally, implementations of the standard POSIX tmpnam() and
    tmpfile() functions are provided if required.

    Implementations of mktemp(), tmpnam(), and tempnam() are provided, but
    should be used with caution since they return only a filename that was
    valid when function was called, so cannot guarantee that the file will
    not exist by the time the caller opens the filename.

    Filehandles returned by these functions support the seekable methods.

OBJECT-ORIENTED INTERFACE
    This is the primary interface for interacting with "File::Temp". Using
    the OO interface a temporary file can be created when the object is
    constructed and the file can be removed when the object is no longer
    required.

    Note that there is no method to obtain the filehandle from the
    "File::Temp" object. The object itself acts as a filehandle. The object
    isa "IO::Handle" and isa "IO::Seekable" so all those methods are
    available.

    Also, the object is configured such that it stringifies to the name of
    the temporary file and so can be compared to a filename directly. It
    numifies to the "refaddr" the same as other handles and so can be
    compared to other handles with "==".

        $fh eq $filename       # as a string
        $fh != \*STDOUT        # as a number

    new Create a temporary file object.

          my $tmp = File::Temp->new();

        by default the object is constructed as if "tempfile" was called
        without options, but with the additional behaviour that the
        temporary file is removed by the object destructor if UNLINK is set
        to true (the default).

        Supported arguments are the same as for "tempfile": UNLINK
        (defaulting to true), DIR, EXLOCK and SUFFIX. Additionally, the
        filename template is specified using the TEMPLATE option. The OPEN
        option is not supported (the file is always opened).

         $tmp = File::Temp->new( TEMPLATE => 'tempXXXXX',
                                DIR => 'mydir',
                                SUFFIX => '.dat');

        Arguments are case insensitive.

        Can call croak() if an error occurs.

    newdir
        Create a temporary directory using an object oriented interface.

          $dir = File::Temp->newdir();

        By default the directory is deleted when the object goes out of
        scope.

        Supports the same options as the "tempdir" function. Note that
        directories created with this method default to CLEANUP => 1.

          $dir = File::Temp->newdir( $template, %options );

        A template may be specified either with a leading template or with a
        TEMPLATE argument.

    filename
        Return the name of the temporary file associated with this object
        (if the object was created using the "new" constructor).

          $filename = $tmp->filename;

        This method is called automatically when the object is used as a
        string.

    dirname
        Return the name of the temporary directory associated with this
        object (if the object was created using the "newdir" constructor).

          $dirname = $tmpdir->dirname;

        This method is called automatically when the object is used in
        string context.

    unlink_on_destroy
        Control whether the file is unlinked when the object goes out of
        scope. The file is removed if this value is true and $KEEP_ALL is
        not.

         $fh->unlink_on_destroy( 1 );

        Default is for the file to be removed.

    DESTROY
        When the object goes out of scope, the destructor is called. This
        destructor will attempt to unlink the file (using unlink1) if the
        constructor was called with UNLINK set to 1 (the default state if
        UNLINK is not specified).

        No error is given if the unlink fails.

        If the object has been passed to a child process during a fork, the
        file will be deleted when the object goes out of scope in the
        parent.

        For a temporary directory object the directory will be removed
        unless the CLEANUP argument was used in the constructor (and set to
        false) or "unlink_on_destroy" was modified after creation. Note that
        if a temp directory is your current directory, it cannot be removed
        - a warning will be given in this case. "chdir()" out of the
        directory before letting the object go out of scope.

        If the global variable $KEEP_ALL is true, the file or directory will
        not be removed.

FUNCTIONS
    This section describes the recommended interface for generating
    temporary files and directories.

    tempfile
        This is the basic function to generate temporary files. The
        behaviour of the file can be changed using various options:

          $fh = tempfile();
          ($fh, $filename) = tempfile();

        Create a temporary file in the directory specified for temporary
        files, as specified by the tmpdir() function in File::Spec.

          ($fh, $filename) = tempfile($template);

        Create a temporary file in the current directory using the supplied
        template. Trailing `X' characters are replaced with random letters
        to generate the filename. At least four `X' characters must be
        present at the end of the template.

          ($fh, $filename) = tempfile($template, SUFFIX => $suffix)

        Same as previously, except that a suffix is added to the template
        after the `X' translation. Useful for ensuring that a temporary
        filename has a particular extension when needed by other
        applications. But see the WARNING at the end.

          ($fh, $filename) = tempfile($template, DIR => $dir);

        Translates the template as before except that a directory name is
        specified.

          ($fh, $filename) = tempfile($template, TMPDIR => 1);

        Equivalent to specifying a DIR of "File::Spec->tmpdir", writing the
        file into the same temporary directory as would be used if no
        template was specified at all.

          ($fh, $filename) = tempfile($template, UNLINK => 1);

        Return the filename and filehandle as before except that the file is
        automatically removed when the program exits (dependent on
        $KEEP_ALL). Default is for the file to be removed if a file handle
        is requested and to be kept if the filename is requested. In a
        scalar context (where no filename is returned) the file is always
        deleted either (depending on the operating system) on exit or when
        it is closed (unless $KEEP_ALL is true when the temp file is
        created).

        Use the object-oriented interface if fine-grained control of when a
        file is removed is required.

        If the template is not specified, a template is always automatically
        generated. This temporary file is placed in tmpdir() (File::Spec)
        unless a directory is specified explicitly with the DIR option.

          $fh = tempfile( DIR => $dir );

        If called in scalar context, only the filehandle is returned and the
        file will automatically be deleted when closed on operating systems
        that support this (see the description of tmpfile() elsewhere in
        this document). This is the preferred mode of operation, as if you
        only have a filehandle, you can never create a race condition by
        fumbling with the filename. On systems that can not unlink an open
        file or can not mark a file as temporary when it is opened (for
        example, Windows NT uses the "O_TEMPORARY" flag) the file is marked
        for deletion when the program ends (equivalent to setting UNLINK to
        1). The "UNLINK" flag is ignored if present.

          (undef, $filename) = tempfile($template, OPEN => 0);

        This will return the filename based on the template but will not
        open this file. Cannot be used in conjunction with UNLINK set to
        true. Default is to always open the file to protect from possible
        race conditions. A warning is issued if warnings are turned on.
        Consider using the tmpnam() and mktemp() functions described
        elsewhere in this document if opening the file is not required.

        If the operating system supports it (for example BSD derived
        systems), the filehandle will be opened with O_EXLOCK (open with
        exclusive file lock). This can sometimes cause problems if the
        intention is to pass the filename to another system that expects to
        take an exclusive lock itself (such as DBD::SQLite) whilst ensuring
        that the tempfile is not reused. In this situation the "EXLOCK"
        option can be passed to tempfile. By default EXLOCK will be true
        (this retains compatibility with earlier releases).

          ($fh, $filename) = tempfile($template, EXLOCK => 0);

        Options can be combined as required.

        Will croak() if there is an error.

    tempdir
        This is the recommended interface for creation of temporary
        directories. By default the directory will not be removed on exit
        (that is, it won't be temporary; this behaviour can not be changed
        because of issues with backwards compatibility). To enable removal
        either use the CLEANUP option which will trigger removal on program
        exit, or consider using the "newdir" method in the object interface
        which will allow the directory to be cleaned up when the object goes
        out of scope.

        The behaviour of the function depends on the arguments:

          $tempdir = tempdir();

        Create a directory in tmpdir() (see File::Spec).

          $tempdir = tempdir( $template );

        Create a directory from the supplied template. This template is
        similar to that described for tempfile(). `X' characters at the end
        of the template are replaced with random letters to construct the
        directory name. At least four `X' characters must be in the
        template.

          $tempdir = tempdir ( DIR => $dir );

        Specifies the directory to use for the temporary directory. The
        temporary directory name is derived from an internal template.

          $tempdir = tempdir ( $template, DIR => $dir );

        Prepend the supplied directory name to the template. The template
        should not include parent directory specifications itself. Any
        parent directory specifications are removed from the template before
        prepending the supplied directory.

          $tempdir = tempdir ( $template, TMPDIR => 1 );

        Using the supplied template, create the temporary directory in a
        standard location for temporary files. Equivalent to doing

          $tempdir = tempdir ( $template, DIR => File::Spec->tmpdir);

        but shorter. Parent directory specifications are stripped from the
        template itself. The "TMPDIR" option is ignored if "DIR" is set
        explicitly. Additionally, "TMPDIR" is implied if neither a template
        nor a directory are supplied.

          $tempdir = tempdir( $template, CLEANUP => 1);

        Create a temporary directory using the supplied template, but
        attempt to remove it (and all files inside it) when the program
        exits. Note that an attempt will be made to remove all files from
        the directory even if they were not created by this module
        (otherwise why ask to clean it up?). The directory removal is made
        with the rmtree() function from the File::Path module. Of course, if
        the template is not specified, the temporary directory will be
        created in tmpdir() and will also be removed at program exit.

        Will croak() if there is an error.

MKTEMP FUNCTIONS
    The following functions are Perl implementations of the mktemp() family
    of temp file generation system calls.

    mkstemp
        Given a template, returns a filehandle to the temporary file and the
        name of the file.

          ($fh, $name) = mkstemp( $template );

        In scalar context, just the filehandle is returned.

        The template may be any filename with some number of X's appended to
        it, for example /tmp/temp.XXXX. The trailing X's are replaced with
        unique alphanumeric combinations.

        Will croak() if there is an error.

    mkstemps
        Similar to mkstemp(), except that an extra argument can be supplied
        with a suffix to be appended to the template.

          ($fh, $name) = mkstemps( $template, $suffix );

        For example a template of "testXXXXXX" and suffix of ".dat" would
        generate a file similar to testhGji_w.dat.

        Returns just the filehandle alone when called in scalar context.

        Will croak() if there is an error.

    mkdtemp
        Create a directory from a template. The template must end in X's
        that are replaced by the routine.

          $tmpdir_name = mkdtemp($template);

        Returns the name of the temporary directory created.

        Directory must be removed by the caller.

        Will croak() if there is an error.

    mktemp
        Returns a valid temporary filename but does not guarantee that the
        file will not be opened by someone else.

          $unopened_file = mktemp($template);

        Template is the same as that required by mkstemp().

        Will croak() if there is an error.

POSIX FUNCTIONS
    This section describes the re-implementation of the tmpnam() and
    tmpfile() functions described in POSIX using the mkstemp() from this
    module.

    Unlike the POSIX implementations, the directory used for the temporary
    file is not specified in a system include file ("P_tmpdir") but simply
    depends on the choice of tmpdir() returned by File::Spec. On some
    implementations this location can be set using the "TMPDIR" environment
    variable, which may not be secure. If this is a problem, simply use
    mkstemp() and specify a template.

    tmpnam
        When called in scalar context, returns the full name (including
        path) of a temporary file (uses mktemp()). The only check is that
        the file does not already exist, but there is no guarantee that that
        condition will continue to apply.

          $file = tmpnam();

        When called in list context, a filehandle to the open file and a
        filename are returned. This is achieved by calling mkstemp() after
        constructing a suitable template.

          ($fh, $file) = tmpnam();

        If possible, this form should be used to prevent possible race
        conditions.

        See "tmpdir" in File::Spec for information on the choice of
        temporary directory for a particular operating system.

        Will croak() if there is an error.

    tmpfile
        Returns the filehandle of a temporary file.

          $fh = tmpfile();

        The file is removed when the filehandle is closed or when the
        program exits. No access to the filename is provided.

        If the temporary file can not be created undef is returned.
        Currently this command will probably not work when the temporary
        directory is on an NFS file system.

        Will croak() if there is an error.

ADDITIONAL FUNCTIONS
    These functions are provided for backwards compatibility with common
    tempfile generation C library functions.

    They are not exported and must be addressed using the full package name.

    tempnam
        Return the name of a temporary file in the specified directory using
        a prefix. The file is guaranteed not to exist at the time the
        function was called, but such guarantees are good for one clock tick
        only. Always use the proper form of "sysopen" with "O_CREAT |
        O_EXCL" if you must open such a filename.

          $filename = File::Temp::tempnam( $dir, $prefix );

        Equivalent to running mktemp() with $dir/$prefixXXXXXXXX (using unix
        file convention as an example)

        Because this function uses mktemp(), it can suffer from race
        conditions.

        Will croak() if there is an error.

UTILITY FUNCTIONS
    Useful functions for dealing with the filehandle and filename.

    unlink0
        Given an open filehandle and the associated filename, make a safe
        unlink. This is achieved by first checking that the filename and
        filehandle initially point to the same file and that the number of
        links to the file is 1 (all fields returned by stat() are compared).
        Then the filename is unlinked and the filehandle checked once again
        to verify that the number of links on that file is now 0. This is
        the closest you can come to making sure that the filename unlinked
        was the same as the file whose descriptor you hold.

          unlink0($fh, $path)
             or die "Error unlinking file $path safely";

        Returns false on error but croaks() if there is a security anomaly.
        The filehandle is not closed since on some occasions this is not
        required.

        On some platforms, for example Windows NT, it is not possible to
        unlink an open file (the file must be closed first). On those
        platforms, the actual unlinking is deferred until the program ends
        and good status is returned. A check is still performed to make sure
        that the filehandle and filename are pointing to the same thing (but
        not at the time the end block is executed since the deferred removal
        may not have access to the filehandle).

        Additionally, on Windows NT not all the fields returned by stat()
        can be compared. For example, the "dev" and "rdev" fields seem to be
        different. Also, it seems that the size of the file returned by
        stat() does not always agree, with "stat(FH)" being more accurate
        than "stat(filename)", presumably because of caching issues even
        when using autoflush (this is usually overcome by waiting a while
        after writing to the tempfile before attempting to "unlink0" it).

        Finally, on NFS file systems the link count of the file handle does
        not always go to zero immediately after unlinking. Currently, this
        command is expected to fail on NFS disks.

        This function is disabled if the global variable $KEEP_ALL is true
        and an unlink on open file is supported. If the unlink is to be
        deferred to the END block, the file is still registered for removal.

        This function should not be called if you are using the object
        oriented interface since the it will interfere with the object
        destructor deleting the file.

    cmpstat
        Compare "stat" of filehandle with "stat" of provided filename. This
        can be used to check that the filename and filehandle initially
        point to the same file and that the number of links to the file is 1
        (all fields returned by stat() are compared).

          cmpstat($fh, $path)
             or die "Error comparing handle with file";

        Returns false if the stat information differs or if the link count
        is greater than 1. Calls croak if there is a security anomaly.

        On certain platforms, for example Windows, not all the fields
        returned by stat() can be compared. For example, the "dev" and
        "rdev" fields seem to be different in Windows. Also, it seems that
        the size of the file returned by stat() does not always agree, with
        "stat(FH)" being more accurate than "stat(filename)", presumably
        because of caching issues even when using autoflush (this is usually
        overcome by waiting a while after writing to the tempfile before
        attempting to "unlink0" it).

        Not exported by default.

    unlink1
        Similar to "unlink0" except after file comparison using cmpstat, the
        filehandle is closed prior to attempting to unlink the file. This
        allows the file to be removed without using an END block, but does
        mean that the post-unlink comparison of the filehandle state
        provided by "unlink0" is not available.

          unlink1($fh, $path)
             or die "Error closing and unlinking file";

        Usually called from the object destructor when using the OO
        interface.

        Not exported by default.

        This function is disabled if the global variable $KEEP_ALL is true.

        Can call croak() if there is a security anomaly during the stat()
        comparison.

    cleanup
        Calling this function will cause any temp files or temp directories
        that are registered for removal to be removed. This happens
        automatically when the process exits but can be triggered manually
        if the caller is sure that none of the temp files are required. This
        method can be registered as an Apache callback.

        Note that if a temp directory is your current directory, it cannot
        be removed. "chdir()" out of the directory first before calling
        "cleanup()". (For the cleanup at program exit when the CLEANUP flag
        is set, this happens automatically.)

        On OSes where temp files are automatically removed when the temp
        file is closed, calling this function will have no effect other than
        to remove temporary directories (which may include temporary files).

          File::Temp::cleanup();

        Not exported by default.

PACKAGE VARIABLES
    These functions control the global state of the package.

    safe_level
        Controls the lengths to which the module will go to check the safety
        of the temporary file or directory before proceeding. Options are:

        STANDARD
                Do the basic security measures to ensure the directory
                exists and is writable, that temporary files are opened only
                if they do not already exist, and that possible race
                conditions are avoided. Finally the unlink0 function is used
                to remove files safely.

        MEDIUM  In addition to the STANDARD security, the output directory
                is checked to make sure that it is owned either by root or
                the user running the program. If the directory is writable
                by group or by other, it is then checked to make sure that
                the sticky bit is set.

                Will not work on platforms that do not support the "-k" test
                for sticky bit.

        HIGH    In addition to the MEDIUM security checks, also check for
                the possibility of ``chown() giveaway'' using the POSIX
                sysconf() function. If this is a possibility, each directory
                in the path is checked in turn for safeness, recursively
                walking back to the root directory.

                For platforms that do not support the POSIX
                "_PC_CHOWN_RESTRICTED" symbol (for example, Windows NT) it
                is assumed that ``chown() giveaway'' is possible and the
                recursive test is performed.

        The level can be changed as follows:

          File::Temp->safe_level( File::Temp::HIGH );

        The level constants are not exported by the module.

        Currently, you must be running at least perl v5.6.0 in order to run
        with MEDIUM or HIGH security. This is simply because the safety
        tests use functions from Fcntl that are not available in older
        versions of perl. The problem is that the version number for Fcntl
        is the same in perl 5.6.0 and in 5.005_03 even though they are
        different versions.

        On systems that do not support the HIGH or MEDIUM safety levels (for
        example Win NT or OS/2) any attempt to change the level will be
        ignored. The decision to ignore rather than raise an exception
        allows portable programs to be written with high security in mind
        for the systems that can support this without those programs failing
        on systems where the extra tests are irrelevant.

        If you really need to see whether the change has been accepted
        simply examine the return value of "safe_level".

          $newlevel = File::Temp->safe_level( File::Temp::HIGH );
          die "Could not change to high security"
              if $newlevel != File::Temp::HIGH;

    TopSystemUID
        This is the highest UID on the current system that refers to a root
        UID. This is used to make sure that the temporary directory is owned
        by a system UID ("root", "bin", "sys" etc) rather than simply by
        root.

        This is required since on many unix systems "/tmp" is not owned by
        root.

        Default is to assume that any UID less than or equal to 10 is a root
        UID.

          File::Temp->top_system_uid(10);
          my $topid = File::Temp->top_system_uid;

        This value can be adjusted to reduce security checking if required.
        The value is only relevant when "safe_level" is set to MEDIUM or
        higher.

    $KEEP_ALL
        Controls whether temporary files and directories should be retained
        regardless of any instructions in the program to remove them
        automatically. This is useful for debugging but should not be used
        in production code.

          $File::Temp::KEEP_ALL = 1;

        Default is for files to be removed as requested by the caller.

        In some cases, files will only be retained if this variable is true
        when the file is created. This means that you can not create a
        temporary file, set this variable and expect the temp file to still
        be around when the program exits.

    $DEBUG
        Controls whether debugging messages should be enabled.

          $File::Temp::DEBUG = 1;

        Default is for debugging mode to be disabled.

WARNING
    For maximum security, endeavour always to avoid ever looking at,
    touching, or even imputing the existence of the filename. You do not
    know that that filename is connected to the same file as the handle you
    have, and attempts to check this can only trigger more race conditions.
    It's far more secure to use the filehandle alone and dispense with the
    filename altogether.

    If you need to pass the handle to something that expects a filename then
    on a unix system you can use ""/dev/fd/" . fileno($fh)" for arbitrary
    programs. Perl code that uses the 2-argument version of "open" can be
    passed ""+<=&" . fileno($fh)". Otherwise you will need to pass the
    filename. You will have to clear the close-on-exec bit on that file
    descriptor before passing it to another process.

        use Fcntl qw/F_SETFD F_GETFD/;
        fcntl($tmpfh, F_SETFD, 0)
            or die "Can't clear close-on-exec flag on temp fh: $!\n";

  Temporary files and NFS
    Some problems are associated with using temporary files that reside on
    NFS file systems and it is recommended that a local filesystem is used
    whenever possible. Some of the security tests will most probably fail
    when the temp file is not local. Additionally, be aware that the
    performance of I/O operations over NFS will not be as good as for a
    local disk.

  Forking
    In some cases files created by File::Temp are removed from within an END
    block. Since END blocks are triggered when a child process exits (unless
    "POSIX::_exit()" is used by the child) File::Temp takes care to only
    remove those temp files created by a particular process ID. This means
    that a child will not attempt to remove temp files created by the parent
    process.

    If you are forking many processes in parallel that are all creating
    temporary files, you may need to reset the random number seed using
    srand(EXPR) in each child else all the children will attempt to walk
    through the same set of random file names and may well cause themselves
    to give up if they exceed the number of retry attempts.

  Directory removal
    Note that if you have chdir'ed into the temporary directory and it is
    subsequently cleaned up (either in the END block or as part of object
    destruction), then you will get a warning from File::Path::rmtree().

  Taint mode
    If you need to run code under taint mode, updating to the latest
    File::Spec is highly recommended.

  BINMODE
    The file returned by File::Temp will have been opened in binary mode if
    such a mode is available. If that is not correct, use the "binmode()"
    function to change the mode of the filehandle.

    Note that you can modify the encoding of a file opened by File::Temp
    also by using "binmode()".

HISTORY
    Originally began life in May 1999 as an XS interface to the system
    mkstemp() function. In March 2000, the OpenBSD mkstemp() code was
    translated to Perl for total control of the code's security checking, to
    ensure the presence of the function regardless of operating system and
    to help with portability. The module was shipped as a standard part of
    perl from v5.6.1.

    Thanks to Tom Christiansen for suggesting that this module should be
    written and providing ideas for code improvements and security
    enhancements.
