Re: [SailfishDevel] Compile without Scratchbox2 environment

[Yuvraaj Kelkar]

The plan is to package up each Sailfish target into a Docker image to be
used in a CI system.
For my purposes, Docker is a easy-to-use chroot that's also easy to share
and deploy as compared to a virtual machine with a toolchain in sb2.

I do know that sb2 is more than just a chroot with bind mounts, but thats
all I really need: a pre-populated chroot with bind mounts. Docker fits
that bill quite nicely.

No, I don't want multiple targets in the same image.
No, I don't need the management of multiple build targets within the same
Docker image.
I don't want any of the other sb2 features: I dont need Xephyr, I don't
need to automagically run the compiled binary under qemu, etc.

Necessity is the mother of this re-invention.
Can you help?

Thanks,

Re: [SailfishDevel] Compile without Scratchbox2 environment

[Yuvraaj Kelkar]

I want to create a Docker image for Sailfish development.
I know it is possible to create a Docker image with sb2 in it; I've done
that for other sb2 toolchains - Maemo and Harmattan.
However, those images can only run as privileged Docker containers because
of sb2 bind mounts (I think).

I'd like to avoid being forced to run privileged Docker containers.
Also, running sb2 inside a Docker container seems like inception.

If it is possible to install the Sailfish toolchain without sb2, it should
be possible to capture that into a non-privileged Docker image. (I hope)

The documentation for anything related to scratchbox is either hard to
google or has broken links to maemo.org or is just non-existant.

As to why Docker and not sb2: "Why not?" and "Better documentation"

Thanks,

Re: [SailfishDevel] Ship a sqlite dabase with an app

[Yuvraaj Kelkar]

There are many ways to do this. I can think of at least two:

Static linking:
1. As the first step of your compilation, create the db file.
2. Use an rcc to embed the sqlite file into the application binary.
3. During run time, at initialization: check if the sqlite.db exists at a
known path, for eg: "$(dirname $0)/sqlite.db" If found, great! Use it.
4. If not found, Extract the embedded sqlite file into that known path.
5. Continue initialization.

Download from AWS:
1. Upload that sqlite.db to a S3 bucket.
2. Download it during initialization

I would not go for the option of generating that sqlite.db on the user's
machine - primarily because 15 minutes is incredibly long.
The user's patience is precious.

Thanks,
-Uv

  From English Wikipedia:

 The right to remain silent is a legal right recognized, explicitly or by
 convention, in many of the world's legal systems.

 The right covers a number of issues centered around the right of the
 accused or the defendant to refuse to comment or provide an answer when
 questioned, either prior to or during legal proceedings in a court of law.
 This can be the right to avoid self-incrimination or the right to remain
 silent when questioned. The right usually includes the provision that
 adverse comments or inferences cannot be made by the judge or jury 
 regarding
 the refusal by a defendant to answer questions before or during a trial,
 hearing or any other legal proceeding. This right constitutes only a small
 part of the defendant's rights as a whole.

 I will repeat one part.

 *The right usually includes the provision that adverse comments or

 Now let all think, was it ok for Jolla employees (that mostly dominated
 yesterday meeting, check in irc logs who was talking most of the time)
 forcing me to speak and what kind of comments they've made about that.

 While I respect Thomas Perl right to be silent - it's his choice and I
 would like others to respect the fact that I was silent during yesterday's
 meeting. Moreover I clearly stated that I will reply on mailing list after
 meeting which I've did as promised. I just didn't feel that I will have
 equal chances to express myself, when Jolla employees where dominating on
 it.

 Filip

[SailfishDevel] Two prolblems: #1 Telepathy qt5 and #2 OpenSSL

[Yuvraaj Kelkar]

Hello all.
I'm trying to port my application from Maemo/Harmattan to Sailfish.

Problem 1:
One of the dependencies is telepathy-qt.
In Maemo/Harmattan this used to be installable/searchable as
telepathy-qt4-devel

From what I understand, in Sailfish, I'm supposed to use telepathy-qt5.
I ssh'd into the mersdk VM and did a sudo zypper install telepathy-qt5
As I had assumed, this doesn't install it into the sb2 environment of course.

I added a PKGCONFIG += TelepathyQt5 to my pro file (found out from Google).
However that didn't work either.

I then entered the sb2 environment and tried to install telepathy-qt5.
This too didn't work: No root privileges.

What do I have to do to be able to use libtelepathy-qt5 ?

Problem 2:
Based on more Googling, I figured out that Sailfish does NOT provide
its own openssl library and expects users to use the statically
compiled version on their own.

I have since then gotten the non-heartbleed openssl, compiled it in
sailfish sb2 for static compilation and managed to link it against my
app.

The question is is this really the correct way to use the openssl library?
It seems unfriendly.

I really hope the answer to #1 isn't compile it yourself and use it.
I can do that, but then I'm not sure thats the right way of doing
things...

Thanks,
Uv

 ...if you want to use it for compilation you need the
 telepathy-qt5-devel package. And no need to ssh in the vm, just go to
 the SailfishOS - Targets tab, click on manage for the desired
 target(s), search for telepathy and install the telepathy-qt5-devel
 package (and whatever else you need).

 I then entered the sb2 environment and tried to install telepathy-qt5.
 This too didn't work: No root privileges.

 If you really want to do this, add -R to sb2 command line. It will
 *appear* to give you root privileges. But as said, you don't need sb2
 for this task.

 Problem 2:
 Based on more Googling, I figured out that Sailfish does NOT provide
 its own openssl library and expects users to use the statically
 compiled version on their own.

 It certainly does *include* openssl library as the heartbleed bug was
 a part of the recent release :)

 Which google hit might have suggested otherwise?
