There was a duplicate cmd.Run() that somehow went unnoticed. It was also
missing an error check, so it was in the code but had no ill effects.
In 86bfacd253 the error check was added.
This caused it to fail every time sure to the cmd already being ran.
Remove the duplicate cmd.Run() altogether.

Using a WaitGroup forced the code to wait for every goroutine to finish.
Using channels allows us to exit early if any of a packages sources need
an update. No point in waiting for the other requests to finish if we
know there is an update.
The update process was already partly parallel: repo, aur and devel
updates where each given their own goroutine.
This gives two further layers of parallelization. Firstly the
`needsUpdate()` function is now run in parallel for each package checked.
One package may have many vcs sources so `needsUpdate()` also checks all
of its sources in parallel.
This gives an aproxamte 3x speedup for `yay -Su --devel` timing from
when the command starts to when the number menu apears.
unfortunately git://bitbucket.org/volumesoffun/polyvox.git never
resolves on my machine for some reason so it always hits the 5 second
timout period.
It then moves on to http:/bitbucket.org/volumesoffun/polyvox.git/ which
does resolve as expected. I have not looked into it but I fear this
applies to all gitbucket repos. Luckly they are few and far between.
Use cacheHome for builddir instead of hardcoding ~/.cache
Use the command names in config.*Bin options.
For example PacmanBin is changed to just "pacman" this means yay will
call the pacman commit in PATH. If the user wants to use a different
binary they can still specify a full path in the config.
Use the command `git ls-remote <url> <branch>` to track devel updates
rather than relying on the GitHub API.
This allows devel update to work for every git based source and
elimantes the rate limiting from GitHub.
The yay_vcs.json format has changed to better support packages which
multiple vcs sources and to track the protocols each source uses. And
track the branch that each source tracks in it's fragment.
Save the VSC Info as soon as the package install finishes. This should
ensure the VSC db does not end up in an incorrect state if an install
fails or is cancelled by the user.
This also adds better support for split packages. When one or more
packages are installed from the same base each individual package is
added to the db not just the base. This allows us to track individual
updates from the same base so that if one package gets updated we don't
assume all packages in the base are updated.
I have replaced the old install and dependancy algorithms with a new
design that attemps to be more pacaur like. Mostly in minimizing user
input. Ask every thing first then do everything with no need for more
user input.
It is not yet fully complete but is finished enough so that it works,
should not fail in most cases and provides a base for more contributors
to help address the existing problems.
The new install chain is as follows:
Source info about the provided targets
Fetch a list of all dependancies needed to install targets
I put alot of effort into fetching the dependancy tree
while making the least amount of aur requests as
possible. I'm actually very happy with how it turned out
and yay wil now resolve dependancies noticably faster
than pacaur when there are many aur dependancies.
Install repo targets by passing to pacman
Print dependancy tree and ask to confirm
Ask to clean build if directory already exists
Download all pkgbuilds
Ask to edit all pkgbuilds
Ask to continue with the install
Download the sources for each packagebuild
Build and install every package
using -s to get repo deps and -i to install
Ask to remove make dependancies
There are still a lot of things that need to be done for a fully working
system. Here are the problems I found with this system, either new or
existing:
Formating
I am not so good at formatting myself, I thought best to
leave it until last so I could get feedback on how it
should look and help implementing it.
Dependancy tree
The dependancy tree is usually correct although I have
noticed times where it doesnt detect all the
dependancies that it should. I have only noticed this
when there are circular dependancies so i think this
might be the cause. It's not a big deal currently
because makepkg -i installed repo deps for us which
handles the repo deps for us and will get the correct
ones. So yay might not list all the dependancies. but
they will get installed so I consider this a visual bug.
I have yet to see any circular dependancies in the AUR
so I can not say what will happend but I#m guessing that
it will break.
Versioned packages/dependencies
Targets and dependancies with version constriants such
as 'linux>=4.1' will not be checked on the aur side of
things but will be checked on the repo side.
Ignorepkg/Ignoregroup
Currently I do not handle this in any way but it
shouldn't be too hard to implement.
Conflict checking
This is not currently implemented either
Split Paclages
Split packages are not Handles properly. If we only
specify one package so install from a split package
makepkg -i ends up installing them all anyway. If we
specify more than one (n) package it will actually build the
package base n times and reinstall every split package
n times.
Makepkg
To get things working I decided to keep using the
makepkg -i method. I plan to eventually replace this
with a pacman -U based method. This should allow passing
args such as --dbpath and --config to aur packages
aswell as help solve some problems such as the split
packages.
Clean build
I plan to improve the clean build choice to be a little
more smart and instead of check if the directory exists,
check if the package is already build and if so skip the
build all together.
