aktualizr-lite's Issues

Weirdness in reading docker-compose.yml

As per:

aktualizr-lite/src/composeapp.cc

Lines 48 to 62 in a69ec9f

 bool ComposeApp::isRunning() { 

 bool cmd_res{false}; 

 std::string cmd_output; 

 std::tie(cmd_res, cmd_output) = cmd("cat " + (root_ / ComposeFile).string()); 

 if (!cmd_res) { 

 LOG_WARNING << "Failed to parse App config: " << name_; 

 return false; 

 } 

 // calculate a number of container images that a given App consists of 

 std::string::size_type find_pos{0}; 

 std::string::size_type line_pos{0}; 

 int expected_container_number{0}; 

 while ((find_pos = cmd_output.find("image:", line_pos)) != std::string::npos) {

It seems odd we are fork/exec cat to read the content of a file.

Additionally, I've been playing some recently with yaml-cpp. Its actually pretty easy to integrate as submodule and hook up with CMake. I think this is probably worth the effort so that we can be more precise.

fw_printenv can't read variables after running aklite-offline

Here is an example:

Even though aklite-offline didn't do anything the u-boot env got "corrupted". Reboot fixes the issue. I'll try to debug a bit more.

writeCurrentTarget called after callback

writeCurrentTarget is called after callback. This means that containers receiving callback might use the outdated information from 'current-target' file.

aktualizr-lite/src/liteclient.cc

Line 264 in 21349f1

writeCurrentTarget(t);

config log dump has some things backwards

Saw this on a device I'm testing (with the server redacted):

[pacman]
type = "ostree+compose_apps"
os = ""
sysroot = ""
ostree_server = "[xxx]"
packages_file = "/usr/package.manifest"
fake_need_reboot = false
/var/sota/compose-apps = "compose_apps_root"
master = "tags"

This is from the log dump that happens when you run with loglevel 0. Notice anything funny? :) It's only the extra bits that aktualizr-lite adds that are backwards, so it looks like a bug here, but it could still somehow be in libaktualizr, I don't know.
