auto-save-unslashify-name/auto-save-slashify-name at WinNT is broken 23 years, 6 months

Konstantin Malakhanov

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. In XEmacs 21.2 (beta35) "Nike" [Lucid] (i586-pc-win32) of Fri Sep 08 2000 on NEVERYON configured using `configure UNKNOWN' I get an error during auto-saving if I set auto-save-directory to some NT directory. To store the whole path in the file name, auto-save-name-in-fixed-directory uses auto-save-unslashify-name to replace \\ in file path by \\\\. But this doesn't work for WinNT, as backslahes are not allowed in file name at any case. This work for storing auto-save files in the original directory (with auto-save-directory nil), as in this case backslashes are part of the path and not of the file name. Maybe with auto-save-directory set, backslashes should be replaced by any other unusual character, like vertical bar? -- Konstantin Malakhanov ISOWARE GmbH, Feithstr. 142, 58097 Hagen, Germany email: km(a)isoware.de Tel: 02331/8019-71 FAX: 02331/8019-99

Yah... but the thing is that when building the Debian packages, the XEmacs binary distribution gets split into several packages. There's going to be a `support-bin' package that contains the "lib-src" stuff, a package with the undumped `*.elc' code, and another with the uncompiled `*.el' and dumped `*.elc'. And of course, there will be several `editor-binary' packages; one for `mule', another for `mule+canna+wnn', one for `vanilla', one for `minimalist', etc. (my packager setup is very configurable. I plan to support in-house or site-customized *.deb builds complete with dumped-lisp.) What I've done is to run an extra configure just for the `support-bin'; but that still links in a bunch of extra stuff... and then when the packageing tools run the `dpkg-shlibdeps' to compute a Depends line for the debian/control, it puts in `ncurses' etc. when those binaries really don't need to depend on that. I could get by just leaving it there, but I'm a perfectionist. It screws up the graph. Stephen> Ie, it's an expensive optimization that probably doesn't buy much. Stephen> It's only with the recent proliferation of special-purpose libraries, Stephen> which depend on other special-purpose libraries, that it really starts Stephen> to make sense. It turns out to not be very hard to just not link them to all that extra stuff to begin with. Perhaps that's true often enough that it's not worthwhile to implement a cure for it in `ld'? I've no way to know yet, really; I don't know what `ld' really does; I've never tried to read its sources. Perhaps I could understand it now if I tried... a year or so ago I could not have. Hmmm. When it runtime link edits, it must have to walk lists of libraries that are listed in the libs and binary as being linked... walk symbol tables and link location tables... So why can't `ld' do the similar at link time (make a tick in an assoc table for each lib as it's referrenced), and not write into the finished product list items for libs not ever referenced? Perhaps then a switch should be provided that tells it to just do what I say, not what I mean? -- Smarter than a phoo phish am I, soon freed when be I weird.

Well, I am running XFree86 4.0.1, installed from a binary tarball obtained from xfree86.org. It has only given me the static version. On my laptop, running stock redhat 6.2, there is also only the static version. Regards, Barry.

Hmmm... Perhaps it does the "right thing" on some OS but not others? Could it be the `ld' thing I asked about? Perhaps some vendor's `ld' will not link everything you list, but only the ones actually referenced? (Unless you give it a DWIS switch, perhaps, in some ideal universe?)

I vaguely remember Martin> having implemented this stuff years ago. Martin> Please let me know exactly what is broken for you. I'll have to double check... Ok; just did... All of the "lib-src" binaries aside from the `gnus*' are compiled with ${ldflags} on the CC line. ${ldflags} is built using ${ld_libs_general}, which looks like: ld_libs_general=-ldl -ldb -lgpm -lncurses -L/usr/lib -lesd -laudiofile -lm -lpq -lldap -llber -lm -lutil -lgcc -lc -lgcc /usr/lib/crtn.o ... in the "lib-src/Makefile" for the XEmacs I'm typing in right now... Hmmm. `ldd' shows them *not* to be linked to all that stuff though... Ah, ok. I just looked again... in the GNUMakefile... I have that `ld_libs_general=' line sharped out, like in the patch for "lib-src/Makefile.in.in" I pasted when I asked the questions that started this thread. Prior to that, all of them, shown by `ldd' output, had been linked to everything in that ${ld_libs_general=} list. So, I conclude that we should patch it out, at least on GNU/Linux. The question remains: will it still work right on other OS then? Martin> Xauth requires Xau, which requires Xt, which requires X11, which Martin> requires ICE and SM... (maybe). Check out the dependencies using ldd Martin> (I haven't). If a shlib does *not* have a `ld' link against a library it calls a routine from, but a final binary links that called-on library itself, does everything just work, or must the shlibs be built with explicit interdependancy information specified on the link command line? How and where could I find the answer to that question and others it may bring up (ones an instructor or tutor would lead me to ask) without asking in *this* mailing list? ;-) Yous seem like the types who don't mind my questions overmuch... Hmmm... lemme think... Seems like the interdependancies probably have to be declared explicitly when the shlib is linked, so that the shlib itself can be link editted at initial mmapping time. Is that right? If so, then using `ldd' on those shlibs _will_ produce a valid answer to the question of whether `gnuserv' and `gnuclient' are linking only required libraries. 8-) Alright... what I want is libXau and anything it requires plus anything they require... Ok. The results. On my Debian GNU/Linux "Woody" machine, with XFree86-4.0.1 prerelease test packages installed, I find that only a static ("*.a") Xau is installed, and it comes from the `xlibs-dev' package... bittersweet% dpkg --status xlibs-dev Package: xlibs-dev Status: install ok installed Priority: optional Section: x11 Installed-Size: 76292 Maintainer: Branden Robinson <branden(a)debian.org> Source: xfree86 Version: 4.0.1-0phase2v12 Replaces: xbase (<< 3.3.2.3a-2), xdevel, xpm4g-dev, xmanpages, xlib6g-dev (<< 4.0), xlib6g-static Provides: libxpm4-dev, xmanpages Depends: xlibs, libc6-dev Conflicts: xdevel, xlib6g-dev (<< 4.0), xlib6g-static, xpm4g-dev, xmanpages Description: X Window System client library development files xlibs-dev provides static versions of the libraries provided in xlibs, as well as several libraries that do not exist in shared object form for various reasons (such as the fact that their API's have not stabilized). Include files and manual pages are also provided. . The libraries only available in static form include libFS, libXau, libXdmcp, libXfontcache, libXinerama, libXss, libXv, libXxf86dga, libXxf86misc, libXxf86rush, libXxf86vm, libfntstubs, liboldX, libxf86config, libxkbfile, and libxkbui. Checking on a Debian 2.2 (Potato) machine reveals that with XFree86-2.2.6, the package name is `xlib6g-dev', but the situation is the same in that there is *only* a static libXau.a provided. Using `ldd' on "libXau.a" produces "Not a dynamic executable". Linking `gnuserv' and `gnuclient' without anything specified but -lXau produces working executables. 8-) I will submit a patch and ChangeLog to the patch queue shortly.
