Comment(by hamish):

 Hi,

 a few cleanups and fixes applied to devbr6 in r56443. The main problem
 there was GRASS_RENDER_IMMEDIATE always being set to TRUE, which in GRASS
 6 always triggers the PNG driver instead.

 Now the error message is by d.rast (e.g.) and has to do with the monitor
 not accepting connections. Interestingly enough, if I have the x0 XMONITOR
 started and selected (on linux) and the cairo driver selected as the wxGUI
 rendering mode, it renders to the Xmon much like the old tcl/tk GUIs
 would.

 But as for the Cairo driver, trying to start it still locks up the wxGUI,
 as per the original bug report, so is currently commented out.
 {{{
RunCommand('d.mon', start = 'cairo')
 }}}

 I had an hourglass mouse cursor on the Map Display window, and could not
 change tabs or do anything with the Layer Manager window, although if I
 dragged it around and moved other windows over the top of it it still
 looked ok after dragging them off. But I had to use `xkill` to get rid of
 it, as neither the Map Display or the Layer manager's "X" window
 decoration worked.

Comment(by hamish):

 some slight improvement in devbr6 with r56444, but still more to do.

 is there a reason for the temp .ppm files not to live in
 /tmp/grass6-$USER-$PID/ with gisrc for easier cleanup if something crashes
 or MS Windows happens? If the files are left open maybe it means that the
 gisrc temp dirs don't get deleted on MS Windows then..?

 oh, and GRASS_RENDER_IMMEDIATE is now ''not'' set at the time that d.mon

 Ok, I've changed the code, now the proxy should be supported...
 see attachement: g.extension.diff

 (Un)fortunately I'm not behind a proxy, therefore I cannot test...

 If someone can test the changes, then I can commit...



 Note: I changed the global variables from lower to capitals (PEP8).

 Hi,

 it's better for points now, thanks, but still some small tweaks needed
 elsewhere. comments as I go:


 tested Spearfish's bugsites map in devbr6, looked ok. when tested in the
 old 6.4.3svn version only a thin line rendered until I moved the
 z-exaggeration slider off 0.0 to 1.0. (which seems like a nice default)


 fwiw there doesn't seem to be a need to abbreviate exaggeration to exag.
 since there is lots of space to the right of it for the text.


 restarting the GUI in devbr6 and adding Spearfish's roads did not go well,
 nothing rendered, lots of this repeating in the terminal:

 Spearfish geology (area) did not render at all. Perhaps it could check
 'v.info -t' via vector.vector_info_topo() and if a vector map containing
 area features is loaded pop up a warning and offer to render the
 boundaries-as-lines instead?


 Going to the wxNVIZ Data tab at that point and trying to add a raster
 didn't work, the drop down showed the current mapset and PERMANENT, but no
 maps within them and no '>' triangle or so to click to expand them. I

 Hi,

 please also check if the http_proxy, ftp_proxy, etc. environment variables
 exist, that's quite widely supported convention and quite handy for those
 that need it set for everything.

 I'm not sure which should have precedence if it is set multiple ways, I
 guess the command line option before the envrio. variable.

 If the environment variables exist and user does not specify new one with:
 http_proxy, ftp_proxy, etc. the environment variables are used. Looking at
 the python docs:

 {{{
 # Use proxies from environment - both versions are equivalent
 filehandle = urllib.urlopen(some_url, proxies=None)
 }}}


 > I'm not sure which should have precedence if it is set multiple ways, I

 IMHO, if the user specify the http_proxy parameter on the module this
 should have the precedence.

Using a module:
r.mapcalc "newmap = null()"

Using C code:

int row, nrows;
int data_type;
void *buf;

data_type = 

/* open raster map ... */

buf = Rast_allocate_buf(data_type);

Rast_set_null_value(buf, Rast_window_cols(), data_type);

nrows = Rast_window_rows();

for (row = 0; row < nrows; row++) {
Rast_put_row(buf, data_type);
}

/* close raster map ... */

 Yes. A "$" in an "export" command is almost always wrong.

 There '''might''' be a situation where "`export $LD_LIBRARY_PATH_VAR`" is
 required, but I think that LD_LIBRARY_PATH_VAR is normally substituted
 rather than ending up in the final script.

You need to provide more information: version, OS, any error or debug
messages generated.

I don't have this problem with 7.0 on Linux.

But first, check that it isn't an OS issue. "ulimit -n" reports the
maximum number of open files (in 7.0, you need two per map). Also,
each completed raster needs a subdirectory within the cell_misc
directory, and some filesystems impose a limit on the number of
subdirectories (often much lower than the limit on the number of
files).

 The location of the temporary directory is chosen by the init script,
 which doesn't "publish" the location directly. If GRASS was started using
 the init script, the directory can be inferred from $GISRC, but there's no
 reliable way to know whether GRASS was actually started using the init
 script.

 Most uses of G_tempfile() are wrong (including its use by g.tempfile), but
 there isn't an official API for obtaining a normal temporary directory.
 AFAICT, the only code which should actually be using G_tempfile() is
 lib/raster/open.c and lib/raster3d/open.c.

 In light of that, G_tempfile() should probably be changed to use a similar
 mechanism to the init script (possibly by having the script set
 GRASS_TMPDIR), and a new function created for the code which requires the
 existing behaviour (i.e. requires that the temporary file is within the
 mapset directory so that rename() and link() work).

Comment(by hamish):

 Ok, if $GISRC is custom you'd get tmp files in weird places. (render.py
 could test if the getenv string started with "/tmp/grassX-" before using
 that, otherwise use $TMPDIR?)

 Right or wrong, many modules leave left-over files in $MAPSET/.tmp/,
 either due to design or a crash, and wherever they are it's rather nice
 that they get cleaned up automatically by the clean_temp program (if users
 wish to bypass normal startup and not run clean_temp, then it's their
 responsibility to look after that manually). What I am looking for with
 the `dirname $GISRC` idea is some way to replicate that auto-cleanup for
 GUI .ppm files that are forgotten, undeletable-at-runtime on Windows, and
 the residual results of the GUI crashing before cleaning itself up.

 it's probably mainly of concern for large raster maps, where it's not a
 concern at all since in $MAPSET/.tmp/, but fwiw it's good to consider that
 /tmp/ is often on a much smaller filesystem than $GISDBASE. For example,
 v.in.ascii might make a multi GB tempfile during its scanning step.

 > Most uses of G_tempfile() are wrong

 what's the potential downside of that? why "wrong" instead of "different"?
 i.e. is it theoretically wrong or practically wrong?


 thanks,

Done. While on the topics of wikis, I'd mention it is a goal this
year to have the students' blogs regularly appear on the
planet.osgeo.org aggregator site.

Anna, Pietro: if you like, you might wish to sign yourselves up
as extra backup mentors for the interactive scatter plot project,
since Michael is already backup mentor for all projects and I
wouldn't like to stretch anyone too thin. :)

congrats to all, we were spoilt for choice this year, all

 Other look fine. It is the v.rast.stats script which gave problems on

thanks, I don't think Martin will either, but the more the

sometimes it seems that gsoc projects (in general, not specifically

encourage to flatten it out for more community engaement. that
doesn't really apply to Stepan, more to help welcome in/integrate

 perhaps g.parser is looking for "v.rast.stats" but only "v.rast.stats.py"
 exists in the %PATH%, and it is missing the ".py" extension association?
 (that only works in the DOSbox window, not the MSys one AFAIK, and GRASS7
 doesn't have the .bat file wrappers in bin/)

 what does "set" say at the GRASS cmd.exe prompt? is ";.PY" known?

 do other python scripts like r3.in.xyz work there?

 The init script uses TMPDIR or TEMP or tempfile.gettempdir(), and only
 falls back to /tmp as the last resort.

 If /tmp (or $TMPDIR) is on a different filesystem to the mapset, it's
 likely to be faster, e.g. /tmp is likely to be on a local disc even if the
 mapset is on an NFS or CIFS share.

In which case, that isn't the problem.

What type of filesystem are you using? ext2 has a limit of 32768
subdirectories, increased to 64000 in ext4. I know that btrfs has a
rather low limit on the number of hard links (which normally
determines the maximum number of subdirectories, as each
subdirectory's ".." entry is a hard link to its parent).

> indeed:
> ulimit -n unlimited
> bash: ulimit: open files: cannot modify limit: Operation not permitted

You can't increase a soft limit above the corresponding hard limit,
and you can't increase a hard limit unless you're root (and sudo won't
work because the limits are per-process, so ulimit has to be a shell
built-in). On a system which uses PAM, the limits are normally set on
login based upon the contents of /etc/security/limits.conf.
