Re: [SailfishDevel] /var/log is not writable. Where do I create my logs then?

[Erik Ridderby]

Hi,

How is this $XDG_CACHE_HOME created? Is that something you setup in the
yaml-file? Because even though /var/log is read only /var/log/my-app can be read
and write without problem.
I think that if the installer can create $XDG_CACHE_HOME and put the right
permissions it would work.

Ugh sorry, didn't read far enough:

Question answered. Have nice day ;-)

[SailfishDevel] requiring libpulse.so.0

[Victor Mataré]

Hi all,

I'm writing an app that provides a GUI for the PulseAudio network transparency 
features (i.e. module-tunnel-sink, possibly add RTP support later), but in 
https://github.com/sailfish-sdk/sdk-harbour-rpmvalidator/blob/master/allowed_requires.conf
 I see that I can't require 
libpulse.so.0. Does that mean I just can't put it in the RPM deps, or am I 
actually prohibited from even linking against libpulse altogether?

If so, why is that? Does it mean that no app that uses the full PulseAudio API 
can ever get into the Harbour?

Greetings and thanks for any clarification,
Victor

Re: [SailfishDevel] /var/log is not writable. Where do I create my logs then?

[Artem Marchenko]

P.S.
Actually harbour FAQ tells to put at least my cache files to
$XDG_CACHE_HOME subdir that is /var/log/harbour-myapp . So I guess having
/var/log unwritable is a bug then

[SailfishDevel] /var/log is not writable. Where do I create my logs then?

[Artem Marchenko]

Hi All

/var/log is not writable by user nemo, so what is a good location for my
log files then?

I log certain events to journalctl, but I also would want app specific log
file(s) for longer term analysis. /var/log looked like a good place,
because it is standard and cleaned once in a while, so I don't need to care
about deleting own old logs.

So is /var/log not writable by mistake?
Or where shall I create my log files instead?
And do I have to clean them myself or can I somehow register them for
deletion once a month or so?

Cheers,
Artem.

As libiphb is not guaranteed to be accurate, I set the Insomniac to wake up a 
few seconds before I need the alarm to trigger, then start a Timer. You could 
do the same: Wake up, check time and start a normal Timer.
Or am I missing something?

[SailfishDevel] Scheduling code for execution at x seconds since epoch

[Arvid Fahlström Myrman]

Hi,

Does anyone know if it is possible to schedule code for execution at x seconds 
since epoch, with guaranteed execution even when in sleep mode? Currently I am 
using libiphb (through tanghus's Insomniac QML plugin), but libiphb only seems 
to support waiting for a specified number of seconds, meaning that if iphb_wait 
is called when the time is 1394730709733 milliseconds since epoch and is 
instructed to wait for 5 seconds, the code will be executed sometime around 
1394730714733 milliseconds since epoch. I want to be able to schedule code to 
be run at e.g. 1394730715000 (±50 ms or some such small margin), i.e. whole 
seconds since epoch, no matter the current time. That way for example 
WallClock from org.nemomobile.time would be in sync with my timer, and I could 
accurately reflect the remaining time in the GUI by updating on onTimeChanged 
without having to update the GUI unnecessarily often, in addition to other 
simplifications I would be able to make.

Using the standard QtQuick Timer type would work, since it supports specifying 
the interval in milliseconds, so you could do something like timer.interval = 
1394730715000 - Date.now(), however Timer doesn't work when in sleep mode.

Regards,
Arvid

Re: [SailfishDevel] Folder permissions

[Jonni Rainisto]

Did you remember to add %ghost in .spec files for rpm to claim ownership for 
files that you created? Afaik with that remove will also remove the files when 
package is uninstalled.

Thank you very much, I've just tested my game using the XDG basedir and it 
worked so I can continue my port of the game by modifying the rest of the code.

Just one question, will the folders under .config/.cache/.local be removed if I 
uninstall the game? I've noticed that using the XDG basedir to read the 
environment variables I get something like: // but no 
folder is created, so I programmatically created the  folder and 
placed my config (read/write) files.

Since the GUI from the emulator doesn't uninstall the actual game I ssh into 
the emulator and called "zypper remove " and it was uninstalled but 
the folders with all their contents I had created weren't erased. If this 
happens in the actual device then at some point there isn't going to be any 
space available on the device.

Re: [SailfishDevel] SilicaListView.scrollToBottom() after appending to a listmodel

[chriswilty]

Well, the response was underwhelming...

In any case, I sort of solved my issue by using the currentItem/Index way, 
although when adding the first new item, I do get a strange delay before the 
animation kicks in. When adding items after that, it works fine.

Excuse the noobie question, I must be doing something obviously wrong... So 
hopefully the old hands can help.

I have a SilicaListView backed by a ListModel, and a pulley-menu command to add 
an item to the end of the model via ListModel.append(). After adding, I want to 
scroll the SilicaListView to the bottom to make the newly added item visible. 
So I thought using scrollToBottom() would do just that:

function addNewItem() {
  myListModel.append({ "role1": 0, "role2": 0 });
  mySilicaListView.scrollToBottom();
}

However, the view scrolls to the item above the one I just added, as if the 
view has not yet updated. Should I be binding the scrollToBottom() call to 
ListView.onAdd() instead? And if so, should I do that in my function so that it 
is only bound when first needed, for efficiency reasons? Or am I doing this all 
wrong, should I be using currentItem and highlightFollowsCurrentItem instead?

Many thanks,
Chris
