mwptools shutting down by itself while trying to open a log file. about mwptools HOT 24 CLOSED

The blackbox log file please.
Actually, there will so be a $HOME/mwp_stderr_2018-07-20.txt log as well, that will be useful too (or more generally mwp_stderr_YYYY-MM-DD.txt)

from mwptools.

Here are the files.
blackbox_log_2018-07-19_064530.TXT
mwp_stderr_2018-07-20.txt

from mwptools.

Ok, sadly it works here, sort of. There are a number of invalid / corrupt entries in the log, which mwp should survive (it does here), however it fails to find a location -- but nothing bad happens.

Apologies for the piecemeal requests; which Linux (disto, release (i.e Ubuntu xx.yy)) please.

from mwptools.

Yes that's strange.It was working fine with the same log file before update.I am using ubuntu18.04 LTS.

No worries and please let me know if any other files needed.Thanks.

from mwptools.

Unfortunately, it works in my Ubuntu 18.04 VM (hosted on Linux, using kvm). Both the extant master and the updated development branch (which does a better job of working out which are the valid logs -- actually non-trivial).

If possible, you might have a try with development; if nothing else (if it doesn't crash), the work in process flight stats.

development, Ubuntu 18.04

from mwptools.

Okay i will try development branch.Could you please guide me how can i install development branch.

from mwptools.

Apologies, I assume far too much (in the following, mwptools is the mwptools source directory).

cd mwptools
git pull
git checkout development
git pull
make && sudo make install

To get back to master, substitute master for development

from mwptools.

I think i need to read more about linux commands and stuff.Sorry for asking to spoon feed:(

I tried to install development but got this error.
ninja@ninja-VirtualBox:~/Projects/mwptools$ git pull Already up to date. ninja@ninja-VirtualBox:~/Projects/mwptools$ git checkout development error: pathspec 'development' did not match any file(s) known to git.

from mwptools.

At the moment master and development are the same.

cd mwptools
git checkout master
git pull
make && sudo make install

btw did you originally create the project from a zip file or git clone ?

from mwptools.

and what does

git branch -r

show ?

from mwptools.

I followed the installation video to install.

ninja@ninja-VirtualBox:~/Projects/mwptools$ git branch -r
origin/HEAD -> origin/master
origin/master

from mwptools.

Thanks. I'll have to have a think about that --- tomorrow.

from mwptools.

No worries.I will also try to install it again on my home computer as this is my work PC.Thanks and have a great weekend.

from mwptools.

My git-fu improves!

The default instruction only set up the master branch (in order in minimise the initial setup) .
In order to access other branches:

git remote set-branches origin '*'
git fetch -v

Then:

$ git branch
  development
* master

And one can checkout development

$  git checkout development
Switched to branch 'development'
Your branch is up to date with 'origin/development'.

from mwptools.

This is probably fixed in both master and development now.

I installed ubuntu-18.04 again from scratch on Oracle VM VirtualBox(Version 5.2.16 r123759 (Qt5.6.2) and its behaving in a same way and shutting down by itself while trying to open a log file.While its opening i could see the position of map changing to the location in my log file but after few seconds,mwp shuts down and disappears.

from mwptools.

OK, i'll push a debug branch (with instructions) tomorrow (UK evening).

from mwptools.

Thanks.

A few hours ago I was almost convinced that this was a problem with the way that mwp was doing a number of asynchronous event; now my suspects are:

• Video drivers (not liking the background zoom)
• Virtualbox / Win 10
• Combination of the above
• Something else to do with async I/O

So let's see. The easiest way is to start from the bottom. So I've split out the bbox processing into a simple standalone application (well two actually, doing the same thing in slightly different ways).

So please download the attached Zip file, then (in an Ubuntu terminal)
bbox_test.zip

unzip bbox_test.zip
cd bbox_test/
make
# FILE is blackbox file, GEOUSER is a geonames user name (optional)
 ./runme.sh FILE GEOUSER 

Then post back mwp_bbox0.log and mwp_bbox1.log

You should see something like:

$ ./runme.sh blackbox_log_2018-07-19_064530.TXT a_user_name

Here are the files.Thanks
mwp_bbox0.log

from mwptools.

OK, so Ubuntu on VBox handles the async IO correctly as well; next step is to turn off the background map zoom while analysing logs. For this we need the latest development branch.

cd mwptools
git remote set-branches origin '*'
git fetch -v
git checkout development
git pull
make && sudo make install

Now run it from the terminal with a specific environment (with and without the async map zoom).

# Async zoom, may crash
MWP_NOLOG_REDIRECT=1 mwp 2>> /tmp/bbsync.log
# No async zoom, see if this helps
MWP_NOLOG_REDIRECT=1 MWP_BB_NOZOOM=1 mwp 2>> /tmp/bbnosync.log

And let me have the two log files /tmp/bbsync.log and /tmp/bbnosync.log please, and let me know what happens.

from mwptools.

Its working now!!
Both Async zoom and No Async zoom worked from the terminal.
I think newer development build did the trick.Any idea why it wasn't working before?
I also tried to run from the desktop icon and its working now.
bbsync.log
bbnosync.log

from mwptools.

Thanks. No idea what the previous problem was. I now need to tidy a couple of things and document some new setting options then I'll merge it to master, tomorrow. Done.

# back to master 
git checkout master

from mwptools.

I think we're done on this, closing.
