= Overview / analysis of failing bzr-svn imports =

An attempt to classify persistently failing bzr-svn code imports by cause.

<<TableOfContents>>

== Bazaar does not support something present in Subversion ==
=== Unable to convert Subversion path ... because it contains characters invalid in Bazaar. ===
 * https://code.launchpad.net/~vcs-imports/choco/trunk
 * https://code.launchpad.net/~vcs-imports/enlightenment/trunk

=== bzr doesn't support newlines in symlink targets yet ===
 * https://code.launchpad.net/~vcs-imports/freeswitch/trunk

== bzr-svn bugs ==

=== bzr-svn confused by read access restrictions to subtrees ===
 * https://code.launchpad.net/~vcs-imports/open64/trunk

This feels painful to deal with. I want to blame svn for being silly.

=== KDE layout related - Empty parent '...' added, but child '...' wasn't added !? ===
[[Bug:638492|bzr-svn bug 638492]]
 * https://code.launchpad.net/~vcs-imports/kdesupport/trunk
 * https://code.launchpad.net/~kb9vqf/trinity-desktop/kdevelop
 * https://code.launchpad.net/~kb9vqf/trinity-desktop/kdeedu
 * https://code.launchpad.net/~kb9vqf/trinity-desktop/kdenetwork
 * https://code.launchpad.net/~kb9vqf/trinity-desktop/kdebase
 * https://code.launchpad.net/~kb9vqf/trinity-desktop/kdelibs

Fixed in bzr-svn 1.0.5dev.

=== CHKInventoryRepository(...) has no revision ... ===
 * https://code.launchpad.net/~vcs-imports/subvertpy/trunk-svn

Fixed in bzr-svn 1.0.5dev.

=== bzrlib.errors.InconsistentDeltaDelta ===
 * https://code.launchpad.net/~gary/zc.buildout/trunk

=== Bug converting symlink changed to regular file - Checksum mismatch ===
[[Bug:638697|bzr-svn bug 638697]]
 * https://code.launchpad.net/~vcs-imports/kdebase/trunk

Fixed in bzr-svn 1.0.5dev.

== broken svn server ==

<<Anchor(codeplex)>>
=== [codeplex.com] assert svn_revprops.has_key(properties.PROP_REVISION_DATE) ===
[[Bug:498925|bzr-svn bug 498925]]
 * https://code.launchpad.net/~vcs-imports/screengrab/screengrab-1-series
 * https://code.launchpad.net/~mwhudson/irony/trunk
 * https://code.launchpad.net/~pedro-sam-coelho/smartvoice/trunk

This is caused by a server side bug present in the Microsoft Team Foundation Server to Subversion bridge running on codeplex.com. 

I'm inclined to close these as wontfix since they are a server side issue. Perhaps we can look into importing natively from the team foundation server using bzr-tfs ? -- jelmer

== Subversion bugs ==
=== get_log REPORT failed, Subversion breaks on non-UTF8 character in log message ===
[[Bug:312043|subversion bug 312043]]
 * https://code.launchpad.net/~vcs-imports/jeliot3/trunk
 * https://code.launchpad.net/~vcs-imports/ebdl/trunk
 * https://code.launchpad.net/~vcs-imports/iterm/trunk
 * https://code.launchpad.net/~swish-e/swish-e/trunk
 * https://code.launchpad.net/~vcs-imports/greenstone/greenstone3

=== get_dir PROPFIND failed, Subversion breaks on XML-tag-name-invalid character in property name ===
[[Bug:203975|subversion bug 203975]]
 * https://code.launchpad.net/~vcs-imports/pypy/trunk

== Launchpad code bugs ==

<<Anchor(kde-layout)>>
=== Launchpad uses "guessed" layout rather than a layout that matches the requested branch ===
 * https://code.launchpad.net/~vcs-imports/soprano/trunk
 * https://code.launchpad.net/~vcs-imports/project-neon/trunk
 * https://code.launchpad.net/~vcs-imports/k3b/svn-trunk
 * https://code.launchpad.net/~vcs-imports/konversation/trunk
 * https://code.launchpad.net/~vcs-imports/choqok/trunk
 * https://code.launchpad.net/~robby/tellico/trunk
 * https://code.launchpad.net/~claydoh/kmymoney/trunk

== Some analysis done, culprit uncertain ==
=== get_uuid PROPFIND failed ===
This failure mode seems to correspond with being unable to make a successful PROPFIND against the repository root URL. This can be because:
 * There is some sort of erroneous redirect occurring:
  * https://code.launchpad.net/~vcs-imports/imagemagick/trunk
 * Only a subtree of the repository is visible, and accessing the root causes a 401:
  * https://code.launchpad.net/~vcs-imports/alpine/trunk
  * https://code.launchpad.net/~vcs-imports/magento/trunk
  * https://code.launchpad.net/~vcs-imports/openfreeway/trunk
  * https://code.launchpad.net/~vcs-imports/pyohio/trunk
  * https://code.launchpad.net/~vcs-imports/zoneminder/trunk

== Needs investigation ==

=== SSL Verification error: signed using insecure algorithm ===
 * https://code.launchpad.net/~vcs-imports/amanierp/trunk

Happens using "svn log" as well.

=== AssertionError("%d != %d" % (len(tview), tview_len)) ===
 * https://code.launchpad.net/~tully.foote/ros/trunk

Jelmer suggested that recreating the branch from scratch would work, but a fresh import created after the 10.09 rollout also failed the same way: https://code.launchpad.net/~vcs-imports/ros/trunk
