> Key: HAWQ-888
> URL: https://issues.apache.org/jira/browse/HAWQ-888
> Project: Apache HAWQ
> Issue Type: Bug
> Components: Build
> Reporter: Paul Guo
> Assignee: Lei Chang
>
> After building with pgcrypto, plr, orca, the git repos will have the
> following tracked files.
> Changes not staged for commit:
> (use "git add/rm <file>..." to update what will be committed)
> (use "git checkout -- <file>..." to discard changes in working directory)
> deleted: gp-xerces/git_keep_empty_directory.readme
> deleted: gporca/git_keep_empty_directory.readme
> deleted: gpos/git_keep_empty_directory.readme
> deleted: postgres/git_keep_empty_directory.readme
> deleted: ../../src/pl/plr/git_keep_empty_directory.readme
> Those files are just to remind developers to not write the directory (git
> does not save empty directories). This is really annoying. .gitignore does
> not resolve this issue.
> A simple and elegant solution is:
> git update-index --assume-unchanged
> however followering error is seen after parallel building,
> fatal: Unable to create '/data2/github/incubator-hawq/.git/index.lock': File
> exists.
> If no other git process is currently running, this probably means a
> git process crashed in this repository earlier. Make sure no other git
> process is running and remove the file manually to continue.
> I do not want to waste too much time in digging into git internals, instead,
> I'd try another simple solution:
> - rm -f git_keep_empty_directory.readme; \
> + mv -f gporca.git_keep_empty_directory.readme ..; \
> [ ! -d .git ] && git clone $(gporca_git) . && git checkout
> $(gporca_branch); \
> + mv -f ../gporca.git_keep_empty_directory.readme .; \
