离线编译任意版本chromium
没错， **离线 **且 **任意版本 ** chromium。离线还是要下载必要的代码的，但是可以分步进行，极大的提高编译成功率。
准备
chromium在墙内的git地址可以直接访问 https://github.com/chromium/chromium，
但是稳定的tag限于73以后，73以前的tag代码可以从 https://chromium.googlesource.com/chromium/src/+refs 下载指定的版本。
我以59.0.3071.104为例，下载好tar包：chromium-59.0.3071.104.tar.xz，大小500多M，直接翻墙下载很稳定，或者直接下载 源码离线包
下载最新depot_tools 见 http://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html#_setting_up
安装vs2015社区版，注意必须是update3，设置好INCLUDE环境变量：
C:Program Files (x86)Microsoft Visual Studio 14.0VCinclude;C:Program Files (x86)Windows Kits10Include10.0.14393.0um;C:Program Files (x86)Windows Kits10Include10.0.14393.0winrt;C:Program

安装了别的版本vs的，建议完全卸载掉再安装此版本，否则后再编译链接的时候报错，甚至运行的时候出现异常。
cmd设置环境：
set GYP_GENERATORS=msvs-ninja,ninja<kdb>set GYP_GENERATORS=msvs-ninja,ninja
set GYP_DEFINES=component=shared_library
set GYP_MSVS_VERSION=2015

设置代理， 查看浏览器的代理设置，将其配置到cmd/git环境：
git config --global http.proxy http://127.0.0.1:1080
git config --global https.proxy https://127.0.0.1:1080
set HTTP_PROXY=http://127.0.0.1:1080
set HTTPS_PROXY=https://127.0.0.1:1080
netsh winhttp set proxy 127.0.0.1:1080
set NO_AUTH_BOTO_CONFIG=E: mpchromium59src.boto
set BOTO_CONFIG=E: mpchromium59src.boto

目录初始化 ， 新建编译目录 例如：E: mpchromium59， 把chromium-59.0.3071.104.tar.xz解压到该目录里作为src文件夹，再新建.gclient文件初始化项目(.gclient与src同级)：
echo "" >.gclient， 修改.gclient文件内容：
{
"url": "https://github.com/chromium/chromium.git",
"managed": False,
"name": "src",
"deps_file": ".DEPS.git",
"custom_deps": {},
"safesync_url": "",
},

安装python2.7.9，这个版本才开始有pip支持，2.7.6没有，否则后面又是提示你安装。cmd中直接运行python和pip能成功
安装wget的windows版本，推荐把curl和gnuwin32 也安装了，过程不详述，cmd中直接运行wget和curl能成功。
验证步骤5代理是否成功： curl https://www.google.com 是否正确返回页面
修改
google的下载不能很好的在代理环境下工作（我尝试过NO_AUTH_BOTO_CONFIG 好像也不行），可以借助wget工具下载。
手动测试wget是否能翻墙下载成功 https://storage.googleapis.com/syzygy-archive/builds/official/b8aa6a6d09dadd385a1afed5e71c3bb3514a4c0f/benchmark.zip
是否成功来检查环境是否安装正确。
再修改depot_tools下的download_from_google_storage.py文件 download_from_google_storage.py（已修改）下载
#增加一个方法，采用wget方式下载，注意cmd中的环境变量
#set HTTP_PROXY=http://127.0.0.1:1080
#set HTTPS_PROXY=https://127.0.0.1:1080
def download_url2(src, target):
cmd = "wget --tries=3 --timeout=60 --connect-timeout=30 --no-check-certificate --force-directories " + src + " --output-document=" + target
print "cmd:" + cmd
os.system(cmd)

把原来的下载流程注释掉，并用该方法：
download_url2(file_url, output_filename)
#code, _, err = gsutil.check_call('cp', file_url, output_filename)
#if code != 0:
# out_q.put('%d> %s' % (thread_num, err))
# ret_codes.put((code, err))
# continue </kbd>

把原来的文件检查流程也注释掉：
# Check if file exists.
file_url = '%s/%s' % (base_url, input_sha1_sum)
print 'Check if file exists. file_url:' + file_url
#(code, _, err) = gsutil.check_call('ls', file_url)
#if code != 0:
# if code == 404:
# out_q.put('%d> File %s for %s does not exist, skipping.' % (
# thread_num, file_url, output_filename))
# ret_codes.put((1, 'File %s for %s does not exist.' % (
# file_url, output_filename)))
# else:
# # Other error, probably auth related (bad ~/.boto, etc).
# out_q.put('%d> Failed to fetch file %s for %s, skipping. [Err: %s]' % (
# thread_num, file_url, output_filename, err))
# ret_codes.put((1, 'Failed to fetch file %s for %s. [Err: %s]' % (
# file_url, output_filename, err)))
# continue

再把gn://协议下载改成https://下载，具体参考我修改后的 download_from_google_storage.py 文件
修改 src/build/get_syzygy_binaries.py 文件：方法同上，增加download_url2方法，替换原来的
get_syzygy_binaries.py （已修改）下载
运行&编译
gclient runhooks
生成ninja 编译文件：
cd src
gn gen --ide=vs --filters=//chrome --args="enable_nacl=false" --no-deps outDefault

正式编译
ninja -C outDefault chrome

可能出现的问题及解决
在gclient runhooks这一步，如果报类似这样的错：
Error: Command 'download_from_google_storage --no_resume --no_auth -u --bucket v8-wasm-fuzzer -s src/v8/test/fuzzer/wasm.tar.gz.sha1' returned non-zero exit status 1 in E: mpchromium59

sha1文件找不到，直接在DEPS文件中搜索对应的，将其对应项去掉
{
'action': [
'download_from_google_storage',
'--no_resume',
'--no_auth',
'-u',
'--bucket',
'v8-wasm-fuzzer',
'-s',
'src/v8/test/fuzzer/wasm.tar.gz.sha1'
],
'pattern':
'.',
'name':
'wasm_fuzzer'
},

缺失.git目录导致的问题及解决：
Running hooks: 83% (46/55) apache_win32
________ running 'download_from_google_storage --no_resume --platform=win32 --directory --recursive --no_auth --num_threads=16 --bucket chromium-apache-win32 src/third_party/apache-win32'
in 'E: mpchromium59'options.boto:nul
NOTICE: You have PROXY values set in your environment, but gsutil in depot_tools does not (yet) obey them.
Also, --no_auth prevents the normal BOTO_CONFIG environment variable from being used.
To use a proxy in this situation, please supply those settings in a .boto file pointed to by the NO_AUTH_BOTO_CONFIG environment var.
Running hooks: 89% (49/55) clang_format_merge_driver
________ running 'D:Python27python.exe src/tools/clang_format_merge_driver/install_git_hook.py' in 'E: mpchromium59'
fatal: not in a git directory

因为没有.git目录，在gclient runhooks过程中会提示如上错误，修复也简单：
修改install_git_hook.py加上’–global’选项 ：
subprocess.check_call(
BuildGitCmd('config', '--global', 'merge.clang-format.name',
'clang-format merge driver'))
subprocess.check_call(
BuildGitCmd('config', '--global', 'merge.clang-format.driver',
'clang_format_merge_driver %O %A %B %P'))
subprocess.check_call(
BuildGitCmd('config', '--global', 'merge.clang-format.recursive', 'binary'))
subprocess.check_call(
BuildGitCmd('config', '--global', 'merge.clang-format.version', str(_VERSION)))
