前段时间对网站做了些更新，于是在本地修改了代码，再git push，谁知却得到bash: git-receive-pack: command not found的error，我的git repository是放在hostmonster服务器上面的，之前都是正常的，于是提交ticket给hostmonster的support，得到的答复是他们升级的openssh，通过git+ssh不会再读取.bashrc或.ssh/environment文件，也就是说通过git+ssh没有办法修改PATH了。
没办法了，只能手动将命令的路径补全了，对于git pull/git ps来说，只需要在输入命令的时候增加参数，比如
git clone --upload-pack=/home1/huangzhi/git/bin/git-upload-pack
git push --receive-pack=/home1/huangzhi/git/bin/git-receive-pack
不过每次都输入参数实在麻烦，直接写到配置文件.git/config
[remote "origin"]
uploadpack=/home1/huangzhi/git/bin/git-upload-pack
receivepack=/home1/huangzhi/git/bin/git-receive-pack
然后就可以像以前一样git pull/git ps了。
还有一个问题，那就是capistrano。默认capistrano通过git ls-remote获取最新的commit id，通过git clone来获取最新文件，但是这些命令都没有办法设置upload-pack和receive-pack参数，没办法，只能修改默认的方法定义。
首先是git ls-remote
require 'capistrano/recipes/deploy/scm/base'
::Capistrano::Deploy::SCM::Base.class_eval do
alias_method :origin_scm, :scm
def scm(*args)
if command == "git" and args[0] == "ls-remote"
args[0] = "ls-remote --upload-pack=/home1/huangzhi/git/bin/git-upload-pack"
end
origin_scm(args)
end
end
当命令为git ls-remote的时候，额外加入参数upload-pack
再就是git checkout
require 'capistrano/recipes/deploy/scm/git'
::Capistrano::Deploy::SCM::Git.class_eval do
def checkout(revision, destination)
git = "/home1/huangzhi/git/bin/git"
remote = origin
args = []
args "-o #{remote}" unless remote == 'origin'
if depth = configuration[:git_shallow_clone]
args "--depth #{depth}"
end
execute = []
if args.empty?
execute "#{git} clone --upload-pack=/home1/huangzhi/git/bin/git-upload-pack #{verbose} #{configuration[:repository]} #{destination}"
else
execute "#{git} clone --upload-pack=/home1/huangzhi/git/bin/git-upload-pack #{verbose} #{args.join(' ')} #{configuration[:repository]} #{destination}"
end
# checkout into a local branch rather than a detached HEAD
execute "cd #{destination} #{git} checkout #{verbose} -b deploy #{revision}"
if configuration[:git_enable_submodules]
execute "#{git} submodule #{verbose} init"
execute "#{git} submodule #{verbose} sync"
execute "#{git} submodule #{verbose} update"
end
execute.join(" ")
end
end
这个我没有找个比较优雅的方式，只能直接覆盖原来的方法定义，并在git clone的命令中加入upload-pack。
还有就是当capistrano执行远程命令的时候，同样没有合适的environments，比如执行rake db:migrate的时候，所以需要修改默认的rake命令
set :rake, "source /home1/huangzhi/.bashrc; rake"
这样当执行rake命令执行，首先读取.bashrc，设置合适的environments，然后再执行rake命令。
到此为止，一切又恢复了正常。
