Add repo manifest -o to save a manifest

This can be useful to create a new manifest from an existing client, especially if the client wants to use the "-r" option to set each project's revision to the current commit SHA-1, making a sort of a tag file that can be used to recreate this exact state elsewhere. Signed-off-by: Shawn O. Pearce <sop@google.com>
Add a 'repo manifest' command whose help is the manifest file format

Author	SHA1	Message	Date
Shawn O. Pearce	c7a4eefa7e	Add repo manifest -o to save a manifest This can be useful to create a new manifest from an existing client, especially if the client wants to use the "-r" option to set each project's revision to the current commit SHA-1, making a sort of a tag file that can be used to recreate this exact state elsewhere. Signed-off-by: Shawn O. Pearce <sop@google.com>	2009-03-05 10:32:38 -08:00
Shawn O. Pearce	43c3d9ea17	Add a 'repo manifest' command whose help is the manifest file format This should make it easier for users to discover the file format on their own, and read about it. Signed-off-by: Shawn O. Pearce <sop@google.com>	2009-03-04 14:26:50 -08:00

Shawn O. Pearce	2816d4f387	Set core.bare to true on mirror repositories When creating a mirror repository we will always be using a bare repository. Setting $GIT_DIR/config to have core.bare = true is reasonable and helps Git to recognize the environment it is in. Signed-off-by: Shawn O. Pearce <sop@google.com>	2009-03-03 17:53:18 -08:00
Shawn O. Pearce	44469464d2	Allow repo forall -c on a mirror by using GIT_DIR as pwd We can permit a forall on a mirror, but only if we put the command into the git repository. Signed-off-by: Shawn O. Pearce <sop@google.com>	2009-03-03 17:51:01 -08:00
Shawn O. Pearce	c95583bf4f	Don't permit users to run repo status in a mirror client If a client was created with "repo init --mirror" then there are no working directories present, and no files checked out. Using a command like "repo status" in this context makes no sense, and actually throws back a Pytyon traceback at the console when the underlying commands fail out. We now tag commands with the MirrorSafeCommand type if they are able to be executed within a mirror directory safely. Using a command in a mirror which lacks this base class results in a useful error letting you know the command isn't supported. Bug: REPO-14 Signed-off-by: Shawn O. Pearce <sop@google.com>	2009-03-03 17:47:06 -08:00
Shawn O. Pearce	6a5644d392	Get rid of the horrible android import work around hack Months ago when the Android Open Source Project launched we had some import errors that had to be fixed and worked over. These hacks were here to help users update their clients to newer versions of the imported code. Its very likely all clients have either been deleted, or have been updated and have the fixed imports. So we don't need this hack in repo anymore. If a very ancient client still existed, it would need to be created from scratch anyway, due to the Android cupcake branch merging into master and the manifest changes not being able to be handled correctly by repo. A new client wouldn't have the incorrectly imported code in it, and thus wouldn't need this hack. Signed-off-by: Shawn O. Pearce <sop@google.com>	2009-03-03 13:52:20 -08:00

Jeff Bailey	be0e8ac232	Export additional environment variables to repo forall: REPO_PATH is the path relative the the root of the client. REPO_REMOTE is the name of the remote system from the manifest. REPO_LREV is the name of the revision from the manifest, but translated to something the local repository knows. REPO_RREV is the name of the revision from the manifest. This allows us to do commands like: repo forall -c 'echo "(cd $REPO_PATH && git checkout `git rev-parse HEAD`)"'	2009-03-02 19:32:28 -08:00

Shawn O. Pearce	3778f9d47e	Fix repo prune to work on git 1.6.1-rc3~5 and later Prior to git 1.6.1-rc3~5 the output of 'git branch -d' matched: Deleted branch (.)\. where the subgroup grabbed the branch name. In v1.6.1-rc3~5 (aka a126ed0a01e265d7f3b2972a34e85636e12e6d34) Brandon Casey changed the output to include the SHA-1 of the branch name, now matching the pattern: Deleted branch (.) \([0-9a-f]*\)\. Instead of parsing the output of git branch we now re-obtain the list of branches after the deletion attempt and perform a set difference in memory to determine which branches we were able to successfully delete.
