I making one plugin with Python for Rhythmbox.
I get an randomly error when start the plugin. Then of some seconds I reset Rhythmbox and the plugin run ok.
What will the cases that probably originy the error?
Error:

Using the import to models option, I am importing an XLS file with about 15,000 rows.
With the microtime_float function, the script times and echos out how long it takes. At 29.6 secs, this happens, showing it took less than 30 seconds. At that time, I can see the database has all 15k+ records as expected, no issues there.
Problem is, the browser is kept busy and at 1 min 22 secs, 1 min 55 secs and 2 min 26 secs it prompts me to either wait or kill the process. I keep clicking wait and finally it ends at 2 mins 49 secs.
This is a terrible user experience, how can I cut off this extra wait time?
It's a very basic setup: the route calls importcontroller#import with http get and the code is as follows:
public function import()
{
ini_set('memory_limit', '1024M');
$start = $this->microtime_float();
Excel::import(new myImport, 'myfile.xls' , null, \Maatwebsite\Excel\Excel::XLS);
$end = $this->microtime_float();
$t = $end - $start;
return "Time: $t";
}
The class uses certain concerns as follows:
class myImport implements ToModel, WithBatchInserts, WithChunkReading, WithStartRow
I am having issues using rampUser() method in my gatling script. The request is getting stuck after the following entry which had passed half way through.

I am seeing the following in the log which gets repeated for ever and the log size increases
09:35:46.495 [GatlingSystem-akka.actor.default-dispatcher-2] DEBUG io.gatling.core.controller.inject.open.OpenWorkload - Injecting 0 users in scenario xxSimulation, continue=true

The above issue is happening only with rampUser and not happening with
atOnceUsers()
rampUsersPerSec()
rampConcurrentUsers()
constantConcurrentUsers()
constantUsersPerSec()
incrementUsersPerSec()
Is there a way to mimic rampUser() in some other way or is there a solution for this.
My code is very minimal
setUp(
scenarioBuilder.inject(
rampUsers(2).during(1 minutes)
)
).protocols(protocolBuilder)
I am stuck with this for some time and my earlier post with more information can be found here
Can any of the gatling experts help me on this?
Thanks for looking into it.
It seems you have slightly incorrect syntax for a rampUsers. You should try remove a . before during.
I have in my own script this code and it works fine:
setUp(userScenario.inject(
// atOnceUsers(4),
rampUsers(24) during (1 seconds))
).protocols(httpProtocol)
Also, in Gatling documentation example is also without a dot Open model:
scn.inject(
nothingFor(4 seconds), // 1
atOnceUsers(10), // 2
rampUsers(10) during (5 seconds), // HERE
constantUsersPerSec(20) during (15 seconds), // 4
constantUsersPerSec(20) during (15 seconds) randomized, // 5
rampUsersPerSec(10) to 20 during (10 minutes), // 6
rampUsersPerSec(10) to 20 during (10 minutes) randomized, // 7
heavisideUsers(1000) during (20 seconds) // 8
).protocols(httpProtocol)
)
My guess is that syntax can't be parsed, so instead 0 is substituted. (Here is example of rounding. Not applicable, but as reference: gatling-user-injection-constantuserspersec)
Also, you mentioned that others method work, could you paste working code as well?
I bought a Tontec 2.4 Inch Touchscreen ( http://elinux.org/MZTX-PI-EXT ) for my Raspberry Pi. The touchscreen controller requires the "tsc2007.ko" and "tsp_raspi.ko" kernel modules as described in the elinux post. The tsc2007.ko module is in the Raspbian Kernel tree but the tsp_raspi.ko can be found here: https://github.com/osandov/raspi/tree/master/tsc2007.
I've cross compiled a new Kernel for the Pi with those modules and they load fine and create a /dev/input/event0 device in Raspbian. If I 'evtest' that device and touch the screen, I get output so I know the events are being delivered in Linux:

I installed tslib and ran a quick ts_calibrate. I also made sure that ts_test spit out data when I touched the screen.
I added the following environment variables to /etc/profile for tslib support in Qt5:

I read up on the Qt5 docs and how to get touch events in my app. I have a main Widget and set the appropriate flags in the constructor:
MainWidget::MainWidget(QLabel *parent)
: QLabel(parent)
{
qDebug() << "Setting WA_AcceptTouchEvents on MainWidget...";
// Accept touch events
setAttribute(Qt::WA_AcceptTouchEvents);
setAttribute(Qt::WA_StaticContents);
}
I setup an event filter to try to catch the touch events:
bool MainWidget::eventFilter( QObject* target, QEvent* e )
{
qDebug() << "Event Type: " << e->type();
return false;
return QLabel::eventFilter(target, e);
}
I launch my app like this:
myapp -platform linuxfb:fb=/dev/fb0 -plugin tslib:/dev/input/event0
I also uncommented a single printf in Qt's source code for the qtslib.cpp:
void QTsLibMouseHandler::readMouseData()
{
ts_sample sample;
while (get_sample(m_dev, &sample, m_rawMode)) {
bool pressed = sample.pressure;
int x = sample.x;
int y = sample.y;
// work around missing coordinates on mouse release
if (sample.pressure == 0 && sample.x == 0 && sample.y == 0) {
x = m_x;
y = m_y;
}
if (!m_rawMode) {
//filtering: ignore movements of 2 pixels or less
int dx = x - m_x;
int dy = y - m_y;
if (dx*dx <= 4 && dy*dy <= 4 && pressed == m_pressed)
continue;
}
QPoint pos(x, y);
//printf("handleMouseEvent %d %d %d %ld\n", m_x, m_y, pressed, sample.tv.tv_usec);
QWindowSystemInterface::handleMouseEvent(0, pos, pos, pressed ? Qt::LeftButton : Qt::NoButton);
m_x = x;
m_y = y;
m_pressed = pressed;
}
}
When I launch my Qt app I see the plugins are loading OK ( even shows the correct event0 file ). I also see that the qt tslib plugin is receiving touch events when I touch the screen. The problem is that the event filter is NEVER called!
Here is the app being launched:

I found a few forum posts where people are having problems with touch input with the linuxfb platform plugin:
http://comments.gmane.org/gmane.comp.lib.qt.user/5686
http://qt-project.org/forums/viewthread/35757
http://qt-project.org/forums/viewthread/36120/
I've tried all their suggestions and still have the problem - no touch events are received by my app even though the Qt tslib plugin says it is receiving them.
It seems that the tslib plugin is having problems injecting the event it receives into my app's event loop with this:
QWindowSystemInterface::handleMouseEvent(0, pos, pos, pressed ? Qt::LeftButton : Qt::NoButton);
I also tried the Qt5.4 touch fingerpaint example and see the same behavior - no touch events are received.
I'm not sure where to go from here. I would greatly appreciate any help solving this issue. Thanks!
UPDATE:
I changed my event filter so it looks like this:
bool MainWidget::eventFilter(QObject *obj, QEvent *event)
{
qDebug() << "Event received" << obj->metaObject()->className() << event->type();
switch (event->type()) {
case QEvent::TouchBegin:
qDebug() << "TouchBegin";
case QEvent::TouchUpdate:
qDebug() << "TouchUpdate";
case QEvent::TouchEnd:
qDebug() << "TouchEnd";
{
// QTouchEvent *touch = static_cast<QTouchEvent *>(event);
// QList<QTouchEvent::TouchPoint> touchPoints = static_cast<QTouchEvent *>(event)->touchPoints();
// foreach (const QTouchEvent::TouchPoint &touchPoint, touchPoints) {
// switch (touchPoint.state()) {
// case Qt::TouchPointStationary:
// // don't do anything if this touch point hasn't moved
// continue;
// default:
// {
// }
// break;
// }
// }
// break;
}
//default:
//return QLabel::event(event);
}
//return true;
}
Now I can see 'socket notifier' events intermingled with Qt Tslib Plugin's prints whenever I touch the screen. Any ideas as to why Event Type 50 but no Touch Events?
Event received QSocketNotifier 50
handleMouseEvent 2702 2618 0 557715
Event received QSocketNotifier 50
handleMouseEvent 2698 2612 1 547758
Event received QSocketNotifier 50
handleMouseEvent 2706 2802 1 759928
Event received QSocketNotifier 50
Event received QSocketNotifier 50
UPDATE #2:
I installed the event filter only to try to catch any events. I'm not sure in Qt5 what translates an event type 50 ( QSocketNotifier ) to a QTouch* or QMouse* event.
Here is some more information:
When I run evtest, I see that the screen resolution is huge ( ~2500 x
~2500 ) and the actual screen is 320x240. I tried changed the
/dev/fb0 framebuffer size in /boot/config.txt to 320x240 and
rebooted. But the evtest and ts_calibrate steps still show the huge
resolution.
Because of the large resolution, I tried making my main widget
10000x10000 to see if I would get a touch or mouse event - but I
still only get the QSocketNotifier
I then tried to force the tslib plugin to always inject events at
screen position X=50 Y=50, but I still only get the event type 50
QSocketNotifier.
The problem was solved by making sure the tslib plugins were installed on the RasbperryPi.
TSLIB_PLUGINDIR=/usr/lib/ts
The directory /usr/lib/ts was not present on the Pi.

I tried the command:
WriteXLS("my matrix after i converted it to data.frame", "test.xls")
but I got this error:
The Perl script 'WriteXLS.pl' failed to run successfully.
I googled it but I couldn't find a solution.
Thanks in advance.
Any reason why you can't just use write.csv?
write.csv(mymatrix, "test.csv")
Import it in Excel and you're set!
PS: I assume you're not putting quotes around your variable name in the WriteXLS call, right?
One other option on Windows (which seems a reasonable assumption given that you are using Excel):
You can write a matrix (or data frame) to the clipboard using a command like:
write.table(mymat, 'clipboard', sep='\t')
Then just go into Excel, click in the cell that you want to be the top left cell, then do a paste and your matrix is there (the sep='\t' is important for Excel to interpret it correctly).
This is similar to other answers, but you don't need an intermediate file on disk.
You could also check xlsx if you do not mind the Excel 2007 format, as xlsx does not depend on Perl (though depends on rJava).
After loading the packge via library(xlsx) just try the following:
write.xlsx(USArrests, "/usarrests.xlsx")
It's hard to see what is going on here exactly. Might be several things.
I think the easiest way to write a matrix to excell is by using write.table() and importing the data in excell. It takes an extra step but it also keeps your data in a nice format.
If foo is your matrix:
write.table(foo,"foo.txt")
If you get an error maybe trie coercing the object to a matrix:
write.table(as.matrix(foo),"foo.txt")
Does the matrix contain values in the upper triangle as well? Perhaps making a full matrix works:
foo<-foo+t(foo)
write.table(as.matrix(foo),"foo.txt")
But these are all just random shots in the dark since I don't have a matrix to work with.
EDIT: In response to the other answer, you can remove the column and rownames with col.names=FALSE and row.names=FALSE in both write.table() and write.csv() (which are the same function with different default values).
I have met the same problem, after reinstalling strawberry perl : after debugging the WriteXLS function in R, I found out the the perl module Text::CSV_XS was missing from my fresh new install. I installed this module from the DOS command line :
perl -MCPAN -e shell
install Text::CSV_XS
After this, WriteXLS was working fine.
upper # matrix name
write.xlsx2(upper,file = "File.xlsx", sheetName="Sheetname",col.names=TRUE, row.names=TRUE, append=TRUE, showNA=TRUE)
I am beta testing an application that includes a Firefox extension as one component. It was originally deployed when FF3.5.5 was the latest version, and survived 3.5.6 and 3.5.7. However on FF3.6 I'm getting the following in my error console:
Warning: reference to undefined property Components.interfaces.nsIProcess2
Source file: chrome://overthewall/content/otwhelper.js
Line: 55
Error: Component returned failure code: 0x80570018 (NS_ERROR_XPC_BAD_IID)
[nsIJSCID.createInstance]
Source file: chrome://overthewall/content/otwhelper.js
Line: 55
The function throwing the error is:
48 function otwRunHelper(cmd, aCallback) {
49 var file =
50 Components.classes["#mozilla.org/file/local;1"].
51 createInstance(Components.interfaces.nsILocalFile);
52 file.initWithPath(otwRegInstallDir+'otwhelper.exe');
53
54 otwProcess = Components.classes["#mozilla.org/process/util;1"]
55 .createInstance(Components.interfaces.nsIProcess2);
56
57 otwProcess.init(file);
58 var params = new Array();
59 params = cmd.split(' ');
60
61 otwNextCallback = aCallback;
62 otwObserver = new otwHelperProcess();
63 otwProcess.runAsync(params, params.length, otwObserver, false);
64 }
As you can see, all this function does is run an external EXE helper file (located by a registry key) with some command line parameters and sets up an Observer to asynchronously wait for a response and process the Exit code.
The offending line implies that Components.interfaces.nsIProcess2 is no longer defined in FF3.6. Where did it go? I can't find anything in the Mozilla documentation indicating that it has been changed in the latest release.
The method on nsIProcess2 was moved to nsIProcess. For your code to work in both versions, change this line:
otwProcess = Components.classes["#mozilla.org/process/util;1"]
.createInstance(Components.interfaces.nsIProcess2);
to this:
otwProcess = Components.classes["#mozilla.org/process/util;1"]
.createInstance(Components.interfaces.nsIProcess2 || Components.interfaces.nsIProcess);
You will still get the warning, but the error will go away, and your code will work just fine in both versions. You could also store the interface iid in a variable and use the variable:
let iid = ("nsIProcess2" in Components.interfaces) ?
Components.interfaces.nsIProcess2 :
Components.interfaces.nsIProcess;
otwProcess = Components.classes["#mozilla.org/process/util;1"]
.createInstance(iid);
