kiwix::fileExists only checks for file existence now
kiwix::fileReadable will check if the file is readable (implicitly checking for file existence also)
Use a heap allocated buffer (with lifetime of Aria2 class) instead of
a stack allocated one.
Original fix made by @ZaWertun. Kudos to him.
Fix #kiwix/kiwix-desktop#123, kiwix/kiwix-desktop#513
and kiwix/kiwix-desktop#423
Downloader::startDownload has a new parameter option which is a vector of
pair that represents the options that can be set for adding a uri with aria2
with the function Aria2::addUri.
Aria2::addUri uses this parameter to set the struct of parameters for the
aria2 command
Api changes :
- removeLastPathElement do not takes extra arguments
`removePreSeparator` and `removePostSeparator`.
This is not needed as path do not need special tailing separator.
- Only one function `split`. Arguments can be implicitly convert to
string. No need for overloading functions to explicitly cast them.
- `split` function takes another argument `trimEmpty`. If true, empty
element are removed.
Path manipulation now almost pass trough a vector<string> to store each
path's part.
Most of the complex works is now made in the normalizeParts function.
There are two executable path :
- The user one (the appimage path)
- The real one (in the appimage archive)
When we search of `library.xml` we need the user one.
But when we search of `aria2c` or `kiwix-serve` we need the real one.
Fixkiwix/kiwix-desktop#256
This functions enable to stop and resume download with aria2.
The Downloader's constructor now checks the paused downloads with the
function "tellWaiting()" to get them at the start of kiwix-desktop.
Mingw doesn't implement it. So, we should not use it.
I suppose that it was working before because mingw package for debian trusty
simply no provides a "thread" header.
We may face to include the native "thread" header.
The `common` name is from the time where kiwix was only one repository
for all the project (android, desktop, server...).
Now we have split the repositories and kiwix-lib is the "common" repo,
the "common" directory is somehow nonsense.
By default, we are searching in the PATH env var.
However, with an appImage, the executable directory is not in the PATH,
so we have to use an absolute path if we can.
If we cannot find the aria2c executable in the executable directory let's
try to use the system one.
