v.digit broken on new WinGrass release

[cnielsen]

Vector digitizing windows open properly, both in the tcltk and the new wxpython menu item.

However after a feature is digitized, as I right-click to finish the feature, the window closes and the following error message shows up in the "Output" window or "Command output" tab depending on the GUI

v.digit map=test2@user1

hmmm, worked for me in my test with "v.digit -n" which did not open an existing map.

Hamish

[hamish]

looking at the F_open code in question (lib/form/open.c), there seem to be #ifdefs in there around the UNIX socket code already, so why would it be disabled?

Hamish

[cmbarton]

Could it be the fully qualified map name (map@mapset)?

I can reproduce this now from both the wx and tcltk GUIs.

digitize [new] -> settings -> table tab -> create table -> ok

(interestingly the dbf.exe empty dosbox locked up when I tried to run it from gis.m)

then draw a boundary with "No category" set, move vertex to snap it shut, then try to add a centroid with cats set to "Next not used". Boom, G_fatal_error( "F_open_*() doesn't do ms windows").

In my earlier test I didn't try to do anything with an attribute table.

I expect that the tcl version of d.what.vect will have the same problem as it also uses the form library.

Replying to cmbarton:

Could it be the fully qualified map name (map@mapset)?

it's this in lib/form/open.c:

/* Open new form
 *
 *  returns: 0 success
 */
#ifdef __MINGW32__
int F_open(char *title, char *html)
{
    G_fatal_error("F_open is not supported on Windows");
    return 1;
}
#else
int F_open(char *title, char *html)
{
    /* parent */
    int c;

    /* common */
    static int pid;

#ifndef HAVE_SOCKET
    static int p1[2], p2[2];
#endif /*HAVE_SOCKET */
    int length;

    /* child */

    G_debug(2, "F_open(): title = %s", title);

    if (first) {
#ifdef HAVE_SOCKET
...

the question is, is that fatal error really necessary if all the UNIX socket code is protected?

bumping up the priority level of this bug as currently there is no vector digitizing functionality available on MS Win, which is not a good situation.

Workarounds: use the qgis digitizer or cygwin build.

Hamish

[cmbarton]

This is too bad, especially since we just finally got this easily available to Windows users.

it's this in lib/form/open.c:

Huh? That matches the error message, but v.digit shouldn't be using lib/form. It has its own embedded copy of the form library.

Oh. develbranch_6 has LIBES=$(FORMLIB) in vector/v.digit/Makefile, 6.4.0-RC5 doesn't; see r38954. That explains why v.digit works for me (6.4.0-RC5, native Windows).

or more precisely it happened at r39141, when that Makefile change was backported to the 6.4 branch. so the latest 6.4.0svn40049 native wingrass build I'm testing uses $(FORMLIB), while the 6.4.0rc5 release did not use that.

I am not familiar enough with this part of the code to provide much comment beyond that, only that I am glad that this is not as deep as I feared it could be.

"Own embedded copy" is a good reason for trouble. Before r38954 form lib was out of sync. If lib/form was broken before r38954 then something else was broken too (nviz? d.what?). Unfortunately I have no idea about sockets/pipes on windows. According to lib/form history, Glynn should have an idea how sockets/pipes/etc. works on Windows.

By "embedded", I mean "in-process". The form library in lib/form consists of a custom "wish" which has a command for executing SQL, and a library which spawns this as a slave process. The version in v.digit doesn't use a separate child process; the form code has been merged into the main v.digit program (which is also a custom wish).

The separate form library is still used by nviz and d.what.vect.

Unfortunately I have no idea about sockets/pipes on windows. According to lib/form history, Glynn should have an idea how sockets/pipes/etc. works on Windows.

I don't have much of an idea either. I do know that Windows doesn't understand Unix-domain sockets (so no socketpair()). It does have a _pipe() function which is roughly equivalent to the Unix version, but the lack of fork() means that creating a slave process is nothing like on Unix.

[marisn]

As lib/forms F_open is used only by v.digit and d.what.vect, it's not worth to fix forms lib. Reverted to old v.digit F_open in r40128. Please test on Windows and backport to releasebranch if it helps.

v.digit doesn't use lib/form (at least, it's not supposed to use lib/form, as it has its own version of the code).

d.what.vect AFAIK doesn't work on Windows due to X dependency. Not a issue. NVIZ does NOT use F_open(). lib/forms are used by more than v.digit and d.what.vect modules, but only those two call F_open(). Others use plain F_generate, which works just fine.

v.digit doesn't use lib/form (at least, it's not supposed to use lib/form, as it has its own version of the code).

Only part of the form lib that could be v.digit own, is F_open() and also only because it's not worth effort to make lib/form F_open() Windows-ready. F_generate() is generic enough to NOT keep many copies around.

v.digit doesn't use lib/form's F_{open,clear,close} functions; it has its own functions with those names, which don't spawn a separate process. Except, linking against lib/form for F_generate() seems to cause lib/form's F_open (etc) to override the local version.

It would be possible to modify v.digit to use different names (this may also need to be done for reset_values(), set_value() and submit() in form.c), but I'm still concerned about the potential side-effects of linking against lib/form. Personally, I consider cloning F_generate() to be the lesser evil.

If d.what.vect is the only module which uses lib/form's F_open(), I'd consider removing that code from lib/form and putting it in d.what.vect instead. That would simplify lib/form and eliminate the Windows issues.

my 1/2c: at some point we have to stop refactoring working code in 6.x. Any new perturbation introduces the potential for new problems and this is supposed to be the stable branch. The old lib/form/open.c + d.what.vect is working fine on UNIX and is irrelevant elsewhere, so my vote is to just leave well enough alone, put things back to the way they were as much as possible, sync whatever bugfixes need syncing between the clones, and move on.

would a more portable version of lib/form do some good in some other area, or is this it?

As removing something from lib/form will break backwards compatability. I attached patch that renames v.digit F_ function copies and removes futurer duplicate code. Worksforme, needs review.

Why does that matter? I'm fairly sure that we don't want anything else using lib/form, particularly F_open().

I attached patch that renames v.digit F_ function copies and removes futurer duplicate code. Worksforme, needs review.

I'm still don't see why we can't just revert the v.digit changes and sync its copy of generate.c to the lib/form copy.

I don't particularly like cloning code, but in this case the cure is worse than the disease.

[hamish]

this is a blocker as 2 of 2 vector digitizers are now broken in current 6.4 wingrass. Fortunately the solution for the tcl one seems well in hand & forthcoming. Will backport revert then sync solution to the 6.4 branch as soon as it is tested & confirmed in 6.5.

FWIW, I've changed 6.5 as I consider appropriate, i.e. removed
$(FORMLIB) and sync'd generate.c to lib/form's version.

tested on a fresh build of grass65 on WinVista32:

=> v.digit is working

Helmut

[hamish]

stuff sync'd/backported from devbr6 to relbr64 with r40401.

while testing it, I noticed this build warning:

proto.h:56: warning: its scope is only this definition or declaration, which is probably not what you want

as far as I can tell in the latest wingrass installer v.digit(tcl) works so this is no longer critical, but I get an unexplained error message when I close it:

Region restored to original extent.
Building topology for vector map <(null)>...
Registering promitives...
Unable to read vector map

I also notice an error in the output:

DBMI-SQLite driver error:
Error in sqlite3_prepare():
near "where" syntax error
Cannot update table

I'm guessing that is because I hit submit (or didn't) in the Form when the only column in the table was cat? (???) the output from v.db.select looks as it should.

?, Hamish

it now works so no longer a blocker, but needs testing as per

[hamish]

as per comment:30 the "Building topology for vector map <(null)>..." + "Unable to read vector map" on close down messages remain, which is a bit of a worry, but overall the module still seems to work so downgrading from 'critical' into the noise.

Feel free to upgrade again if the effects can be felt..

[hamish]

closing bug as original form lib breakage is fixed; closing map <(null)> weirdness continued in #917.
