Release notes
bzr 1.6.1 2008-09-05
-------
A couple regressions were found in the 1.6 release. There was a
performance issue when using ``bzr+ssh`` to branch large repositories,
and some problems with stacking and ``rich-root`` capable repositories.
bzr 1.6.1rc2 2008-09-03
-------
BUG FIXES:
* Copying between ``rich-root`` and ``rich-root-pack`` (and vice
versa) was accidentally using the inter-model fetcher, instead of
recognizing that both were 'rich root' formats.
(John Arbash Meinel, #264321)
bzr 1.6.1rc1 2008-08-29
-------
This release fixes a few regressions found in the 1.6 client. Fetching
changes was using an O(N^2) buffering algorithm, so for large projects it
would cause memory thrashing. There is also a specific problem with the
``--1.6-rich-root`` format, which prevented stacking on top of
``--rich-
fetch experimental data (``-subtree``) without representing it properly.
The ``--1.6-rich-root`` format has been deprecated and users are
recommended to upgrade to ``--1.6.
re-introduced a workaround for users who have repositories with incorrect
nodes (not possible if you only used official releases).
I should also clarify that none of this is data loss level issues, but
still sufficient enough to warrant an updated release.
BUG FIXES:
* ``RemoteTranspo
buffered the readv data and processed it. It would keep appending to
the same string (causing many copies) and then pop bytes out of the
start of the string (causing more copies).
With this patch "bzr+ssh://local" can improve dramatically,
especially for projects with large files.
(John Arbash Meinel)
* Revision texts were always meant to be stored as fulltexts. There
was a bug in a bzr.dev version that would accidentally create deltas
when copying from a Pack repo to a Knit repo. This has been fixed,
but to support those repositories, we know always request full texts
for Revision texts. (John Arbash Meinel, #261339)
* The previous ``--1.6-rich-root`` format used an incorrect xml
serializer, which would accidentally support fetching from a
repository that supported subtrees, even though the local one would
not. We deprecated that format, and introduced a new one that uses
the correct serializer ``--1.6.
