Normaly we only pass --config to pacman if the user specifies it on the
command line. Otherwise we let pacman use it's default config location.
If the user has changed pacmanconf in Yay's config file then this could
cause a miss match between the config we use to init alpm and the config
pacman is using.
Currently we do not handle -Sp, this leads to yay trying a proper
install and failing. So instead pass it to pacman and exit. Ideally we
would extend -Sp to include AUR packages but for now don't bother.
As it turns out, the times you need root also tend to be the time you
need to manipulate the database. So the needWait() function can be
removed and repllaced by needRoot()
* Wait for db.lck to become available before starting a db operation
* Fix err!=nil issues and avoid spamming users
* Remove redundant cases
* Remove return
The order of targets does somewhat matter. For example doing something
like 'pacman -S db1/foo db2/foo' should cause the second package to be
skipped.
The order of targets also effects in which order they are resolved. This
should make errors more reproducable if any ever occur.
This is a rewrite of the dependency system, It aims to be cleaner
written, with a better idea of what is needed from the start, meaning
less new code being hacked on for things that were not thought about.
This version also aims to use as many small functions as possible, for
cleaner code and better testing.
Added dep.go:
general dependency functions
Added depPool.go:
Replacement of depTree, dependencies were never ordered so
a tree did not really make sense. Instead the term pool
makes more sense.
Added depOrder.go:
Replacement of depCatagories, This simply orders the
dependencies, dependencies are still catagorized as repo and AUR
but I believe this to be a better name
Added depCheck.go:
Replaces conflicts.go and also contains the missing dependency
code
This version is mostly the same as the old version with a few
improvments:
Missing packages will print the full dependency tree
Versioned dependency checking errors should be fixed
Make depends should be calculated properly
Experimental AUR provide searcher
This code has been added along side the old code for testing and is not
currently used by the install process. Once the install process is moved
to use this code, the old code will be removed.
Print the full descriptions of each news item.
The description is formatted as html, basic parsing is done to display
it properly. -q/--quiet can be used to diplay title only.
99% of the time if a user wants to pas an argument twice they would do
`-cc` or `--clean --clean`. Still doing `-c --clean` is still a valid
thing to do. This commits allows getArg() to this properly.
Previosuly when reading from stdin we did not redirect back to the real
stdin afterwards so it was imposible to interact with y/n questions.
Now redirect back to "/dev/tty" just like pacman does.
With this The user should never have to manually edit the yay config
file. All options can be set directly through yay using
`yay --<option> <value> --save`
Reformatted comments to have a space between // and the start of the
comment.
Added capital letters and punctuation.
Fixed most grammar and spelling mistakes.
Fixed date to yyyy/mm/dd.
Comments have been added to a couple of functions here and there
where I feel warrent some explanation. Hopefully this makes it a little
easier for people to contribute.
I commented on a couple of functions but my main focus is:
DepTree
DepCatagories
StringSet
Arguments
These are parts that have been mostly written by me and might seem
confusing without taking a while to study the code. Especially the first
two mentioned. They're a little complex, I'm not sure if they need to be
This is just how I came up with them. Hopefully helping other people
understand them will let them come up with improvments I did not see.
I'm not the best at explaining things but I did try my best here.
Options such as --devel are now striped from the parser before handling
the command but the option is still processed so that config.devel would
be true.
Also changed `changedConfig` to a global in config.go
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.
This allows us to use command line options such as '--root' and '-b' when
performing operations that use out alom handle.
Sadly this does not apply to passToMakepkg which will ignore options
such as '--root' and because we pass '-i' to makepkg it installs for us
using the default options.
Currently I have not planned a solution for this but one which I thought
of but not looked into is. Always call makepkg without arguments (except
from '--noconfirm' and others which might still be needed) and manage
the dependancies and post install outselves.
Another option might be to use makepkg's $PACMAN enviroment variable and
redirect the pacman calls to yay. Although I am unsure about both
stratergys they are just my current thoughts.
Also while editing the flow of cmd.go, I managed to refactor away all
os.Exit calls apart from the very last so it should be more clear as to
where the program exits.
Allows globals to be tracked more easily so that thay can be seperated
from normal arguments and passed easily while not passing other
arguments.
Also fixed some missing checks and bugs.
This reimplemens all operations yay previously supported:
'-S' 'Syu' 'Si' ect.
Currently the argument objects are not fully implemented with the code.
Theres alot of funky conversion from
argument object -> pkg, flags -> argument object
This is to just get back to the functionally we had before (almost).
I have not looked into it yet but alot of the time pacman flags get
passed to makepkg. this cases an error for most commands now because the
new system Passes all flags:
`yay -Syu` -> flags = '-S' '-y' '-u'
while the old system would have done:
`yay -Syu` -> op = '-Suy', flags = ''
So extra flags are no longer passed at all currently.
This means:
'yay -S aic94xx-firmware --noconfirm -b /tmp/pacutilesu2q6hw/tmp-pacman -d'
will no longer error and 'aic94xx-firmware' will be installed but the
database path change will not apply and the dep checking will not be
skipped.
