""" Workaround for slow updates from an svn branch to git.

See also jira issue INFRA-9182
|

|

Situation:
|
||||
|
||||
Remove svn repo ---> slow git-svn update process ---> Remote git-svn repo (upstream)

Remote svn repo ---> (slow) git-svn fetch ---> Remote git repo (upstream)

Local svn working copy --> this workaround ---> Local git repo
|
||||
Local svn working copy ---> this workaround ---> Local git repo
|
||||
|
||||
Because of the slow remote git-svn update process the remote git repo is (far) behind
|
||||
When the remote git-svn fetch is slow, the remote git repo is behind
|
||||
the remote svn repo.
|
||||
|
||||
When this script is run it will first check that the local repositories are clean.
|
||||
Then it switches the svn working copy to branch, which updates from the remote.
|
||||
Then it fetches branch from the git upstream repo, and merges the branch locally.
|
||||
When this script is run it will first check that the local working copy and repository are clean.
|
||||
Then it switches the svn working copy to the branch, which updates from the remote.
|
||||
Then it the fetches branch from the git upstream repo, and merges the branch locally.
|
||||
Normally the local svn and git will then be at the same svn revision, and the script will exit.
|
||||
|
||||
Otherwise the remote git repo is out of date, and the following happens.

@ -38,8 +38,12 @@ For the branch branchname in a local git repository following an upstream git-sv
|
|||
this maintains commits on a temporary git branch branchname.svn in the local git repository.
|
||||
These commits contain a message ending like this:
|
||||
"SvnRepoUrl diff -r EarlierSvnRevisionNumber:NextSvnRevisionNumber".
|
||||
Otherwise the added commit messages look a lot like their counterparts from git svn,
|
||||
only the committer is taken from the local git settings.
|
||||
Otherwise the messages of the added commits are the same as their counterparts from git svn.
|
||||
|
||||
Normally the added git commits and their git-svn counterparts have no differences between their working trees.
|
||||
However such differences can occur, see also the documentation of git-svn reset and the limitations below.
|
||||
In order not to interfere with git-svn this script only adds commits to a temporary branch
|
||||
branchname.svn, and the commit messages are chosen differently, they do not contain git-svn-id.
|
||||
|
||||
In case an earlier branchname.svn exists, it will first be deleted if necessary,
|
||||
and restarted at the later branch.
|
||||
|
@ -48,41 +52,38 @@ Therefore branchname.svn is temporary and should only be used locally.
|
|||
By default, no more than 20 commits will be added to branchname.svn in a single run.
|
||||
|
||||
The earlier revision number is taken from the git-svn-id message of git svn,
|
||||
or from the LatestSvnRevisionNumber in the commit message of branchname.svn,
|
||||
or from the latest revision number in the commit message on branchname.svn,
|
||||
whichever is later.
|
||||
|
||||
This allows branchname.svn to be used as a local git branch instead of branchname
|
||||
to develop new features locally, usually by mering branchname.svn into a feature branch.
|
||||
|
||||
In more detail:
|
||||
- switch the svn working copy to the branch, updating it to the latest revision,
|
||||
- in the git repo:
|
||||
- fetch the git repository from upstream.
|
||||
- merge branchname from upstream/branchname, this is the branch that can be (far) behind.
|
||||
- use the git-svn-id from the latest git commit on this branch to determine the corresponding svn revision.
|
||||
- if the branchname.svn exists determine the latest svn revision from there.
|
||||
- choose the latest svn revision number available.
|
||||
- compare the git-svn revision to the svn latest revision (delay deleting a too early branchname.svn to later below).
|
||||
- when the git repository has the same revision:
|
||||
- exit reporting that branchname is up to date.
|
||||
- when the git repository has an earlier revision:
|
||||
- in the git working tree:
|
||||
- if branchname.svn is not at the earlier svn revision number:
|
||||
- delete branchname.svn
|
||||
- recreate branch branchname.svn from branchname.
|
||||
- check out branchname.svn
|
||||
- get the svn commits from the latest available git svn commit (possible generated here), this uses the remote svn repo,
|
||||
to the latest one from the svn log (but no more than the maximum):
|
||||
- for all these commits:
|
||||
- from the svn working copy, create a patch for the svn commit into file ~/patches/branchname.svn,
|
||||
this takes most the the time as it uses the remote svn repo.
|
||||
- in the git working tree:
|
||||
- apply the patch ~/patches/branchname.svn, ignoring whitespace differences.
|
||||
- commit using author, date and message from the svn log, and append the message with revision numbers.
|
||||
to develop new features locally, for example by merging branchname.svn into a feature branch.

This currently works by patching text, and therefore this does not work on binary files.

An example commit in lucene-solr that adds a binary file, on which this currently does not work correctly:

When the local svn working copy contains file after updating to the latest available revision,

This was developed on Linux using the following program versions:

|

""" To be done:
|
||||
Take binary files from the patch, and check out binary files directly from the remote svn repo directly into the local git repo.
|
||||
|
||||
Going really far: checkout each interim svn revision, and use all (changed) files from there instead of the text diff.
|
||||
Determining all files under version control with svn (svn ls) is far too slow for this (esp. when compared to git ls-tree),
|
||||
so this is probably better done by using svnsync to setup a local mirror repository following the remote,
|
||||
and then using svnlook on the local mirror repository.

Doing that only to avoid the limitations of this workaround does not appear to be worthwhile.
