Guy Harris c349caf925 Use AC_SYS_LARGEFILE to turn on large file support on platforms that
support it.

Rename ws_lseek to ws_lseek64, as it should be given a 64-bit offset,
and have it use _lseeki64 on Windows, to try to get 64-bit offset
support; AC_SYS_LARGEFILE should cause lseek() to support 64-bit offsets
on UN*X if possible.

Guy Harris f3502974a0 Point to RFC 1952 as a description of the gzip file format.
Point to pages for some other compressed file formats we might want to
support.

Guy Harris f27f61ac9e Move the definition of the structure pointed to by a FILE_T into
wiretap/file_wrappers.c; nothing outside of file_wrappers.c needs to
know what it looks like, it just passes around pointers to it.

Guy Harris f3873931ec To squelch some compiler warnings, temporarily cast the argument to
ws_lseek() to the appropriate type for the second argument to _lseek()
for Windows or lseek() for UN*X; ultimately, we want to call the
appropriate 64-bit-offset seek routine if available, otherwise cast the
value down and hand it to the 32-bit-offset seek routine.

Guy Harris f73c579d55 From Jakub Zawadzki:
file-wrappers.[ch] is used only for reading files, and mode is always
"rb".

Attached patch removes 'mode' argument from file_open() & filed_open().

Jeff Morriss a5cee04fad Move the file utility functions from wiretap to libwsutil so that
libwireshark (and the plugins using those functions) do not depend on
wiretap on Windows.

While doing that, rename the eth_* functions to ws_*.

Guy Harris 7474bc0f13 If we're using libz, make file_open() construct the open() flag
argument, rather than requiring the caller to get the open() flag and
the fopen() flag in sync.  That also means that if we're *not* using
libz, it can just be a wrapper around eth_fopen().

We need to include <fcntl.h>, at least on UN*X, to get open() declared
and the O_ flags defined.

Ulf Lamping c3187174bf replace *a lot* of file related calls by their GLib counterparts. This is necessary for the switch to GTK 2.6 (at least on WIN32).
to do this, I've added file_util.h to wiretap (would file_compat.h be a better name?), and provide compat_macros like eth_open() instead of open(). While at it, move other file related things there, like #include <io.h>, definition of O_BINARY and alike, so it's all in one place.

deleted related things from config.h.win32

As of these massive changes, I'm almost certain that this will break the Unix build. I'll keep an eye on the buildbot so hopefully everything is working again soon.

Guy Harris 8a8b883450 Set the svn:eol-style property on all text files to "native", so that
they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

Guy Harris 2aad75bb82 Graeme Hewson noted that zlib has a bug wherein "gzseek()" doesn't set
the internal z_err value for the stream if an "fseek()" call it makes
fails, so that if "gzerror()" is subsequently called, it returns Z_OK
rather than an error.

To work around this, we pass "file_seek()" an "int *err", and have the
with-zlib version of "file_seek()" check, if "gzseek()" fails, whether
the return value of "file_error()" is 0 and, if so, have it return
"errno" instead.

Guy Harris 23d1a63f39 zlib 1.0.8 - the version that comes with X11 - does have "gzseek()",
even if it doesn't have "gzgets()", so one might think we could use it
by using our own replacement for "gzgets()".

One would be wrong to think so, however, as the "gzseek()" it has
doesn't actually work when reading uncompressed files.

zlib 1.0.9 has "gzgets()", and fixes that bug, so we rever to checking
for "gzgets()" rather than "gzseek()", so that we don't accept pre-1.0.9
versions of zlib, and we get rid of our "gzgets()" replacement.

Ashok Narayanan 29c8fa03b3 Removed the dependency on gzgetc and gzgets by implementing internal
versions of these commands in file_wrappers.c. This allows us to
compile successfully even on platforms where X has an older zlib built
in.

Removed this restriction from acinclude.m4

Guy Harris 6fa0fd5fa8 Sigh. OpenBSD defines "HAVE_UNISTD_H" in the Makefile for zlib, so,
unlike FreeBSD and older versions of NetBSD, which give "gzseek()" and
"gztell()" signatures with "long" file-offset arguments, and thus, on
some versions, requires that "HAVE_UNISTD_H" *not* be defined before
including "zlib.h" if you want the functions declared with a signature
that matches what's actually in the library, it requires that it *be*
defined before including "zlib.h" if you want the functions declared
with a signature that matches what's actually in the library.

Guy Harris 9f458a52fc Always declare, and define, "file_seek()" to return a "long", as it's
supposed to look like "ftell()".

If you don't have zlib, just define "file_seek" as an alias for "fseek",
rather than defining it as a routine.

Guy Harris f71823a907 "gztell()" is also affected by the libz mess on platforms where "off_t"
is bigger than a "long"; this is itojun's fix for that, turning
"file_tell()" into a wrapper function in "file_wrappers.c", just like
"file_seek()".

Guy Harris cc9a1060ca Fix "ascend-scanner.l" to include "file_wrappers.h" rather than the
defunct "file.h".

Make "file_wrappers.c" include "wtap.h", so that the WTAP_ERR_ZLIB_
values are defined.

2000-01-13 07:18:50 +00:00
Guy Harris 7a36bede0b We are obliged to define HAVE_UNISTD_H in "config.h"; to avoid the
hideous problem on FreeBSD 3.[23] (and perhaps other BSDs) if
HAVE_UNISTD_H is defined before "zlib.h" is included, turn "file_seek()"
into a subroutine defined in a file that *undefines* HAVE_UNISTD_H
before including "zlib.h", so that the *only* call to "gzseek()" is made
from a file that does not have HAVE_UNISTD_H defined when it includes
"zlib.h".

Move "file_error()" to that file while you're at it, so it holds all the
wrappers that hide the presence or absence of zlib from routines to read
capture files.

Turn "file.h", which declared those wrapper functions as well as wrapper
macros, into "file_wrapper.h" - it belongs with the "file_wrapper.c"
file that defines the wrapper functions, not with "file.c" which handles
higher-layer file access functions.

Remove the comment in "configure.in" that explained why defining
HAVE_UNISTD_H was a bad idea, as we're not obliged to define it and work
around the problem.  (The comment in "file_wrapper.c" explains the
workaround.)
