#15538: GHC boot script can't handle Git remote not named origin -------------------------------------+------------------------------------- Reporter: ChaiTRex | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Build System | Version: Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Building GHC | Unknown/Multiple failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Old description:
== Problem
I ran the following to get the sources for GHC to build them:
{{{ git clone -o ghc --recursive http://git.haskell.org/ghc.git }}}
Note especially the `-o ghc` part, which uses the Git origin name `ghc` instead of the default `origin`. When a custom origin name is used, `./boot` fails:
{{{ $ ./boot Traceback (most recent call last): File "./boot", line 193, in <module> check_for_url_rewrites() File "./boot", line 29, in check_for_url_rewrites subprocess.check_output('git config remote.origin.url'.split()).find(b'github.com') != -1 and \ File "/usr/lib/python3.5/subprocess.py", line 626, in check_output **kwargs).stdout File "/usr/lib/python3.5/subprocess.py", line 708, in run output=stdout, stderr=stderr) subprocess.CalledProcessError: Command '['git', 'config', 'remote.origin.url']' returned non-zero exit status 1
$ git config remote.origin.url
$ echo $? 1 }}}
== Solution
`git config branch.master.remote` can be used to get the origin name to use to get the desired URL:
{{{ $ git config "remote.$( git config branch.master.remote ).url" http://git.haskell.org/ghc.git }}}
== Workaround
Rename the origin to `origin`:
{{{ $ git remote rename "$( git config branch.master.remote )" origin $ ./boot Creating libraries/mtl/ghc.mk Creating libraries/unix/ghc.mk Creating libraries/text/ghc.mk ⋮ }}}

Whenever `git config remote.origin.url` fails, a `git rev-parse` command (thanks to freenode/#git/_ikke_ for it) can be used to get the remote name and branch that would be pushed to: {{{ $ git rev-parse --symbolic-full-name --abbrev-ref @{upstream} ghc/coercible $ git rev-parse --symbolic-full-name --abbrev-ref @{upstream} | sed 's/\/.*$//' ghc $ git config "remote.$( git rev-parse --symbolic-full-name --abbrev-ref @{upstream} | sed 's/\/.*$//' ).url" http://git.haskell.org/ghc.git }}} == Workaround Rename the remote to `origin`: {{{ $ git remote rename "$( git config branch.master.remote )" origin $ ./boot Creating libraries/mtl/ghc.mk Creating libraries/unix/ghc.mk Creating libraries/text/ghc.mk ⋮ }}} -- Comment (by ChaiTRex): [Solution in report above fixed for custom branch selection] -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15538#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
