Git not working if color.ui is enabled
100%
Description
I'm using redmine trunk and git 1.6.0.4.
I started a new project, and it didn't work with a working bare repo. Then I found that webrick was outputting this error on its log:
fatal: Not a valid object name master:
with the word "*master*" highlighted in green.
So I went to the bare repo, and running "*git branch*" I saw that the green color was on the branch list too. So I disabled the ui.color locally in that bare repo using:
git config color.ui false
and now redmine sees my repo correctly.
So, I managed to fix it on the git side, but it should be good if redmine could be able to see this by itself, and fix it or warn the user.

My guess is that the issue has to do with some kind of special characters used to put color in the terminal, and that redmine is reading from that output in order to do something with the branch name. If this guess is right, the solution should be stripping that output of any special character before using it for something.
Anyway it's just a guess, I don't know anything about the internal workings of redmine.

Maybe something like this http://www.commandlinefu.com/commands/view/3584/remove-color-codes-special-characters-with-sed but in the context of capturing any git output
Updated by Bernhard Furtmueller over 14 years ago
I had a brief look to:
lib/redmine/scm/adapters/git_adapter.rb
It looks these commands could need additionally the "--no-color" option:
git branch --no-color
git log --no-color
git diff --no-color
git show --no-color
git blame --no-color <- I´m not sure if it´s really neccessary here, but it doesn´t hurt though.

Rodrigo, could you test the attached patch?
Updated by Rodrigo Toledo over 14 years ago
That should probably work. I tried to write a test to prove it, but I don't know how should I get the git_repository that's used in the unit tests without making it from scratch.
Updated by Rodrigo Toledo over 14 years ago
Somehow I cannot reproduce the issue at home, so I cannot confirm that the patch works. On monday I'll test it at work where it originally happened and I'll give confirmation.
Updated by Jean-Philippe Lang over 14 years ago
I can not reproduce either. I have set:
git config --global color.ui autoand everything still works fine (git 1.5.4.3).
Updated by Bernhard Furtmueller over 14 years ago
given that it´s not for every one reproducible, I´d consider git isn´t doing the color.ui=auto thing correctly depending on gits version.
For me "git show" is colored, but when piping it to less it´s uncolored.
(git version 1.6.3.3)

Can anyone confirm this is still an issue?
Updated by Gustavo Delfino over 14 years ago
I am experiencing this exact same problem. git 1.6.2.3 & redmine 0.9.4
Updated by Rodrigo Toledo over 14 years ago
It shouldn't hurt redmine to use --no-color on each command. Just in case.
Updated by Rodrigo Toledo over 14 years ago
I found that in the machine that I had this problem, color.ui was set to "always", maybe this helps anyone trying to reproduce this issue.

- Target version set to 1.0.3
Eric, the fix for that is here: http://github.com/thegcat/redmine/commit/f9583578af6760377b4d46a5b5907f92c8d47e29
I don't think it's possible to selectively activate color other than shelling out to make the change, the change no activates color to always, so if anything ever changes in the color stuff in future git versions, we should notice through the tests. If you don't want that in, just ignore the archive of the git repo.

I was able to reproduce too with a recent git version (1.7.0.4) on current trunk, with color.ui set to always and no other color.* behavior defined (see git config -l|grep color ; it seems git options precedence doesn't always work as you guess).
Applied Felix's patch in r4310.

--no-color still missing in some places. http://ci.finn.de/ is all green, but I suspect it's because tmp/test/git_repository is still the old one. Fixed in r4386.
I tested it with GIT 1.5.6.5 and 1.7.1, if anyone finds a problem with a different version let us know before it's merged in stable branch.

Not all git commands support --no-color (or at least have an explicit colored output…). Did you encounter any test errors? They did all pass when I tested it here.

git show supports it at least from 1.5.6.5.
I don't remember having found a failing test when committed it, but I found this one yesterday when investigating something else:
% RAILS_ENV=test ruby test/functional/repositories_git_controller_test.rb -n test_diff > failing_test_5324.txt 2>&1
See result attached. No output from app/views/common/_diff partial, and when I put the debugger in the view, I saw the diff output was full of color codes.

Odd. Anyway, the sure-fire way would be to add it to GIT_BIN, but I didn't want to add it there lest it breaks something else…
