WinGRASS: spaces in pathnames

[hamish]

Hi,

trying the native stand-alone installer (rev37703) installed in C:\Program Files\GRASS GIS\GRASS-6-SVN to expose/fix some missing quoting.

The icon to start the wxPython GUI directly works, but the Cmd> prompt fails for v.db.select roads where="label ~ 'highway'" with:

Bad file descriptor: Files/GRASS

---

The "GRASS with MSYS" icon doesn't get very far at all due to msys bugs:

in msys.bat :startrxvt section the line

if NOT EXIST %WD%rxvt.exe goto startsh

needs to have %WD%rxvt.exe "quoted" otherwise you get this error in the terminal window: (but it continues anyway)

The system cannot find the path specified.

a few lines later in if NOT "x%*" == "x" start %WD%rxvt -backspacekey ... -e /bin/sh --login -c "%*" it fails with a pop up window:

Windows cannot find 'C:\Program'. Make sure you typed the name correctly, ...

if you "quote" %WD%rxvt it then gives the error that it can not find the program -backspacekey, Make sure that you typed the name correctly, ....

maybe using a newer msys package helps fix these? if not, time to report some bugs to them.

---

also, the grass dirname in msys/etc/fstab needs to be quoted? (do that in mswindows/GRASS-Installer.nsi)

knock these things off one by one... Hamish

[hamish]

also I notice the C:/Program Files/GRASS GIS/GRASS-6-SVN/msys/grass/ dir is empty.

after the "start" patch in msys.bat and changing the pathname to C:/PROGRA~1/GRASSG~1/GRASS-6-SVN in msys/etc/fstab, then I can successfully start the wxPython GUI.

This one isn't an MSys issue, as MSys shouldn't be involved in running the wxPython GUI, or in running commands from it.

Did the shlex fix make it into the version which you're testing?

yes.

I also notice that error after fixes to msys.bat I start grass + msys terminal from C:\Program Files\GRASS GIS\...

looking trough "set" I don't see anything obviously broken.

running v.db.select roads from the msys command line with DEBUG=5 it shows that it gets up to

D2/5: opendir c:/Program Files/GRASS GIS/GRASS-6-SVN\driver\db\

(slash directions verbatim)

then it locks up the msys terminal.

that debug message comes from lib/db/dbmi_base/dbmscap.c

Hi,

the msys maintainers have decided to reject patches that correct spaces-in-pathnames bugs. i.e. installations to C:\Program Files\... just got that much harder.

Bad news about the spaces...

In the new wingrass release (6.4.0rc5 later today) I've updated msys.bat to:

... start "MSYS 1.0" "%WD%rxvt" ...

I can't think of a way the "dir /x" fix could be used within the installer to adjust things to the 8.3 path names, but if someone else can I'll implement it.

The empty grass dir is a mount point for the install directory and allows the grass with msys shortcuts to be executed with msys.bat /grass/bin/grass64 -wxpython etc. I tried quotes in the fstab file but it doesn't work, which means that the grass with msys shortcuts won't work either if installed in a path with spaces.

yeah I realized that after posting,

and allows the grass with msys shortcuts to be executed with msys.bat /grass/bin/grass64 -wxpython etc.

I don't really understand that.

I tried quotes in the fstab file but it doesn't work, which means that the grass with msys shortcuts won't work either if installed in a path with spaces.

it is the fstab file that needs the PROGRA~1 style because it uses whitespace as the column deliminator and has no quoting ability.

msys.bat patch

[hamish]

Hi,

attached is a patch against the latest CVS version of msys.bat which fixes some of the quoting issues. You'll have to rem out the "abort if spaces in pathname" if you want to allow that.

Colin re. fstab: as with %WD% in the patch, maybe you can use %~dps0 to get the 8.3 shortname string somehow? ​http://www.robvanderwoude.com/ntfor.php

As written it seems to abort whether there are spaces in the pathname or not, I just tried it in c:\program files\ and c:\programs\ with the same result. I think I've fixed it, see attached file (I've just attached msys.bat not a patch. I could figure out svn diff for the CVS of msys.bat...).

There's two bugs, one was your typo (hamish), the other I think is a bug in the original msys.bat. Anyway, it successfully converts the path to 8.3 format.

fstab is only needed for the "Grass with msys" shortcuts to work. They work by calling msys.bat with the argument /grass/bin/grass64 -wxpython (see the attached msys.bat lines 97 & 98. To fix this for spaces we have two options though I'm not sure which will work.

1) fstab is written by the installer script with the install path, but I can't find a way to get the nsi script to convert the path with %~dps0 before writing the fstab file.

2) If we can get msys.bat to convert a windows path (from an argument) from (eg):

c:\Program Files\Grass\bin\grass64 -wxpython

to:

/c/Program\ Files/Grass/bin/grass64 -wxpython

then we wouldn't need fstab at all. The shortcut would use the windows style path, and msys.bat would convert it into readable format for msys.bat line 98

thanks for catching that.

(I've just attached msys.bat not a patch. I could figure out svn diff for the CVS of msys.bat...).

cvs -d:pserver:anonymous@mingw.cvs.sourceforge.net:/cvsroot/mingw login

# make changes

cvs -u diff msys/dvlpr/bin/msys.bat > patch.diff

There's two bugs, one was your typo (hamish),

yup

the other I think is a bug in the original msys.bat.

yeah, that was noted by the original patch's author on SourceForge, disregarded as harmless.

Anyway, it successfully converts the path to 8.3 format.

cool

see the attached msys.bat lines 97 & 98.

this: ?

+if "x%*" == "x" start [...] -e /bin/sh --login -i
+if NOT "x%*" == "x" start [...] -e /bin/sh --login -c "%*"

does batch logic know "else"?

should I send that patch upstream?

1) fstab is written by the installer script with the install path, but I can't find a way to get the nsi script to convert the path with %~dps0 before writing the fstab file.

any link to Nsi script help? seems like a fairly developed language; might have a system{} command.

2) If we can get msys.bat to convert a windows path (from an argument) from (eg):

c:\Program Files\Grass\bin\grass64 -wxpython to: /c/Program\ Files/Grass/bin/grass64 -wxpython

then we wouldn't need fstab at all. The shortcut would use the windows style path, and msys.bat would convert it into readable format for msys.bat line 98

GRASS-Installer.nsi has code for that already?

No luck so far, I managed to have the NSI script write a little batch file, which in turn writes the 8.3 shortname to a system variable with SETX. This value is then written to the fstab value, however it always writes the previous value of the variable instead... annoying. Also it is not really preferable to have a system environment variable permanently written for this purpose...

GRASS-Installer.nsi has code for that already?

True but msys still has problems with "/c/Program\ Files/GRASS/bin/grass64" as it strips out the \.

On another similar note, I had an error with v.digit failing to write to the dbf because the GIS Database path had a space in it (which is the default in the installer).

I commited to 6.5 a hack that was sitting in my commit queue for some time. Please test r38898

In case someone is not aware:

we use ​GetShortPathName() in QGIS' GRASS plugin to eliminate blanks from (some) filenames and paths on Windows.

And NSIS has ​GetFullPathName /SHORT

If that doesn't work, my next guess is that the leading and trailing \" are being treated as a literal part of the program name. (?!)

ok, it looks like the extra \" may be to blame then. (if _spawnl() quotes the argument [as it should] then you get ""...\dbf.exe"")

I'll reply here once a fix for that is submitted.

extra quotes removed in r39456,7. try, try again....

​Microsoft's documentation says that the caller needs to quote arguments:

Spaces embedded in strings may cause unexpected behavior; for example, passing _spawn the string "hi there" will result in the new process getting two arguments, "hi" and "there". If the intent was to have the new process open a file named "hi there", the process would fail. You can avoid this by quoting the string: "\"hi there\"".

However: it says "arguments", which doesn't necessarily apply to the command name (and db_start_driver() invokes the driver with no arguments), although it will apply to argv[0] (it shouldn't matter if argv[0] has excess quotes, but if it doesn't have enough it will end up rolling over into argv[1]).

I can confirm that the "can't _spawnl" problem is gone (using the latest winGRASS binary based on r39626).

closing this bug as in general this lot seem to be taken care of and before it morphs into the next set of windows bugs. those can start their own, new tickets.
