Usage:
./sync-all [-q] [-s] [--ignore-failure] [-r repo] [--checked-out] [--bare]
[--<tag>] [--no-<tag>] [--resume]
cmd [git flags]
where <tag> is one of: $tags
Applies the command "cmd" to each repository in the tree.
A full repository tree is obtained by first cloning the ghc
repository, then getting the subrepositories with "sync-all get":
\$ git clone http://git.haskell.org/ghc.git
\$ cd ghc
\$ ./sync-all get
After this, "./sync-all pull" will pull from the original repository
tree.
A remote pointing to another local repository tree can be added like
this:
\$ ./sync-all -r /path/to/ghc remote add otherlocal
and then we can pull from this other tree with
\$ ./sync-all pull otherlocal
-------------- Commands -----------------
get
Clones all sub-repositories from the same place that the ghc
repository was cloned from. See "which repos to use" below
for details of how the subrepositories are laid out.
There are various --<package-tag> options that can be given
before "get" that enable extra repositories. The full list is
given at the end of this help. For example:
./sync-all --nofib get
would get the nofib repository in addition to the usual set of
subrepositories.
remote add <remote-name>
remote rm <remote-name>
remote set-url [--push] <remote-name>
Runs a "git remote" command on each subrepository, adjusting the
repository location in each case appropriately. For example, to
add a new remote pointing to the upstream repositories:
./sync-all -r http://git.haskell.org remote add upstream
The -r flag points to the root of the repository tree (see "which
repos to use" below). For a repository on the local filesystem it
would point to the ghc repository, and for a remote repository it
points to the directory containing "ghc.git".
compare
compare reporoot
compare -b reporoot
Compare the git HEADs of the repos to the origin repos, or the
repos under reporoot (which is assumde to be a checked-out tree
unless the -b flag is used).
1 line is printed for each repo, indicating whether the repo is
at the "same" or a "DIFFERENT" commit.
These commands just run the equivalent git command on each repository, passing
any extra arguments to git:
branch
checkout
clean
commit
config
diff
fetch
format-patch
gc
grep
log
new
new-workdir
pull
push
repack
reset
send
status
tag
-------------- Flags -------------------
These flags are given *before* the command and modify the way sync-all behaves.
Flags given *after* the command are passed to git.
-q says to be quiet, and -s to be silent.
--resume will restart a command that failed, from the repo at which it
failed. This means you don't need to wait while, e.g., "pull" goes through
all the repos it's just pulled, and tries to pull them again.
--ignore-failure says to ignore errors and move on to the next repository
-r repo says to use repo as the location of package repositories
--checked-out says that the remote repo is in checked-out layout, as opposed
to the layout used for the main repo. By default a repo on the local
filesystem is assumed to be checked-out, and repos accessed via HTTP or SSH
are assumed to be in the main repo layout; use --checked-out to override the
latter.
--bare says that the local repo is in bare layout, same as the main repo. It
also means that these repos are bare. You only have to use this flag if you
don't have a bare ghc.git in the current directory and would like to 'get'
all of the repos bare. Requires packages.conf to be present in the current
directory (a renamed packages file from the main ghc repo).
Note: --checked-out and --bare flags are NOT the opposite of each other.
--checked-out: describes the layout of the remote repository tree.
--bare: describes the layout of the local repository tree.
--nofib also clones the nofib benchmark suite
--extra also clone some extra library packages
--no-dph avoids cloning the dph packages
------------ Checking out a branch -------------
To check out a branch you can run the following command:
\$ ./sync-all checkout ghc-7.4
------------ Which repos to use -------------
sync-all uses the following algorithm to decide which remote repos to use
It always computes the remote repos from a single base, <repo_base> How is
<repo_base> set? If you say "-r repo", then that's <repo_base> otherwise
<repo_base> is set by asking git where the ghc repo came from, and removing the
last component (e.g. /ghc.git/ or /ghc/).
Then sync-all iterates over the package found in the file ./packages; see that
file for a description of the contents.
If <repo_base> looks like a local filesystem path, or if you give the
--checked-out flag, sync-all works on repos of form:
<repo_base>/<local-path>
otherwise sync-all works on repos of form:
<repo_base>/<remote-path>
This logic lets you say
both sync-all -r http://example.org/ghc-6.12 remote add ghc-6.12
and sync-all -r ../working remote add working
The latter is called a "checked-out tree".
sync-all *ignores* the defaultrepo of all repos other than the root one. So the
remote repos must be laid out in one of the two formats given by <local-path>
and <remote-path> in the file 'packages'.
