(fcntl fd F_GETLK ...) from Guile

(fcntl fd F_GETLK ...) from Guile

[Kaloian Doganov]

Is there a way to use fcntl's F_GETLK command from Guile?  According
to the docs [1], only the following commands are available:

    F_DUPFD
    F_GETFD
    F_SETFD
    F_GETFL
    F_SETFL
    F_GETOWN
    F_SETOWN
    FD_CLOEXEC

Neighter F_GETLK nor F_SETLK is there.  Am I missing something?  May
be the file locking mechanism is available elsewhere in the Guile
libs?

Yep, not there.  It'd need something for "struct flock" (and "struct
flock64" when available), they're not plain integers like the other
fcntl commands.

There's `flock' already for whole-file, if that's enough.

Yes, currently I don't know how to represent this structure in Guile,
even with those define's suggested by dsmich:

    (define F_GETLK 5)
    (define F_SETLK 6)

I need to do record (range) locking, not whole-file locking, and I
hoped to do it with Guile.

If you don't mind breaking out a little C code it shouldn't be too hard.

(I can never remember which types of locks are voluntary or mandatory,
and which work over NFS or not, etc.  Myself I've only been using flock
on a lockfile to get whole-directory locking.)

I don't mind, but I'm still clueless about C and don't have any
experience in extending Guile with C.

For me, it does "./configure && make && make install" on Linux, but
fails on Cygwin.  Cygwin fails because I don't know how to do DLLs.

Here's what it does on my machine.  Your mileage may vary.

bash-3.1$ guile
guile> (use-modules (getlk))
guile> (define fd (open-output-file "blammo"))
guile> (define lk (fcntl-lk fd F_SETLKW (list F_WRLCK SEEK_SET 0 0

guile> lk

guile> (set! lk (fcntl-lk fd F_SETLK (list F_UNLCK SEEK_SET 0 0
(getpid))))
guile> lk

guile>
  
Good luck.

Mike, I really appreciate your help.
    
    For me, it does "./configure && make && make install" on Linux, but
    fails on Cygwin.

I guess by "Linux" you actually mean GNU/Linux, since the make program
can not run on the bare kernel.  Unfortunately, the configure script
fails on my system (gNewSense):

    Cygwin fails because I don't know how to do DLLs.

I do not plan to use Cygwin, so this is not a problem (for me, at
least).

Try this:   http://lonelycactus.com/getlk-0.1.tar.gz

Anyway, configure failed for you because it did not find the definition
of the type "off_t" in <unistd.h>.  I changed the test to look for it
in <sys/types.h>, because that is where the LSB says it should be.

If it fails again, you should write me directly, as autoconf problems
(and my failings as a coder) are off-topic for the list. ;-)

I don't have any autoconf problems anymore, thank you.

I've just managed to backport your example to Guile 1.6.x. and come up
with the following table of correspondence:

Guile 1.8.x            Guile 1.6.x
--------------         -----------
scm_is_integer         SCM_INUMP
scm_is_true            SCM_NFALSEP
scm_to_int             SCM_INUM
scm_to_int32           SCM_INUM
scm_from_int           SCM_MAKINUM
scm_from_int32         SCM_MAKINUM
scm_to_short (x)       scm_num2short (x, 0, NULL)
scm_from_short         scm_short2num

Not sure whether it is correct, but works for the trivial examples I
run for now.  I don't know what to do with scm_to_int64 and
scm_from_int64, though.

That appears correct.

For many machines 64bits is long long integers. Try scm_num2long_long
and scm_long_long2num.

Yes, Guile seems to be missing those.  These are just numbers, so you can probably just:

  (define F_GETLK 5)
  (define F_SETLK 6)

or whatever the proper values are on your platform.

Here is a patch for libguile/filesys.c to add them.  Untested.

Oops!  Sorry about that.  Just ignore my previous post.
