[-- Attachment #1: Type: text/plain, Size: 10646 bytes --]
Dear all,
I finally had the time to start converting some older Subversion
repositories to git repositiers and run into issues with repos using
"parallel" branches, so-called vendor branches [1] in Subversion to
track upstream changes via snapshots in a separate branch and merge them
into the custom build on trunk.
Just wanting to convert the Subversion history as-is to git.
I studied the git-svn reference docs [2] plus the related chapter of the
ProGit book [3] and assume that I understood how git-svn works.
Still I'm not a git expert, just a sporadic user.
Somehow `git svn fetch` (2.29.2.windows.3) looses merge information
between vendor branch and trunk plus tags are referencing the
predecessors instead of the original ancestor.
Maybe there is a manual way to fix this for that small repository, but
it wouldn't be feasible for larger repositories, that's why I deceided
to write this bug report.
Is there anything I missed? (see my procedure below)
Fortunately I ran quite early into these issues and also with a very
small repository of just 11 commits, so I can provide a small
reproduction case (see below after the links).
Hoping you can enhance `git svn fetch`.
Any help is appreciated, thanks in advance
Matthias Bücher

[Commits in Subversion]
A Subversion repository dump is attached, plus a test where I recreated
the same history directly in a git repository without an issue.
* trunk: a------------d--e--h--i--j--k
* / /
* vendor: a (empty)--b-----f
* ^ ^
* tags: c g
* Vendor releases: b, f
* Custom modifications: e, i, j, k
* Tags: really just used as tags, although Subversion internally they
are branches. Therefore wanting to create lightweight git tags, although
annotated git tags would be fine too.
[Expected Subversion to git repo conversion]
* trunk => branch "main"
* branches/* => branch "*"
* tags/* => tag "*"
* vendor/current => branch "vendor/current" (can be renamed later to
just "vendor")
* vendor/* => tag "vendor/*" (except for vendor/current)
Expected "tags":
vendor/5.4 = rev b (maybe c when annotated)
vendor/5.8 = rev f (maybe g when annotated)
[Wrong Results]
Merges from "vendor/current" branch to trunk get lost.
Tags are referencing the predecessors of the expected commit.

Tested further with re-created Subversion repositories, that either
looked the same but made sure that svn:mergeinfo is present (Subversion
>=1.5 via "cherry pick merge", no "2-URL merge"), or that has the vendor branch being copied from trunk (both attached).
Only when the vendor branch was a copy from trunk, then svn-git got the
merges correct. Otherwise - even with svn:mergeinfo - it does not get
the merges.
Assumption:
It seems that git svn handles trunk and branches in a special way, but
Subversion actually does not have branches.
In Subversion there are just directories and files, and a branch/tag is
just a copy of another directory+revision and merges can happen between
any directories independent if they have related ancestry or not.
Workaround:
As git svn does not recognize all merges correctly (especially
cross-branch copies) those lost links must be added manually.
I wrote a small GNU awk script (attached) to determine all cross-branch
copies from an `svnadmin dump`. This way the first revision when
something got copied is known.
Running git svn just to that revision, then fixing the parents and
continuing with git svn up the next revision.
This helps git svn to find the correct ancestors and correctly build the
follow merges.
The parents can be changed with `git replace -f --graft <commit>
<existing correct parents> <additional correct parents>`.
Additionally before continuing with git svn this `git replace` change
can be made permanent with `git-filter-repo --force --replace-refs
delete-no-add`.

Found a nice tool called reposurgeon [4] that helps a lot to manage
converting a repository from Subversion to git, even in a scriptable
way.
The authors also helped out to determine that my repository has some
awkward commits due to older Subversion versions.
