* ``bzr ls DIR --from-root`` now shows only things in DIR, not everything.

51

(Ian Clatworthy)

53

* We now properly request a more minimal set of file texts when fetching

54

multiple revisions. (Robert Collins, John Arbash Meinel, #390563)

56

53

* Progress bars are now suppressed again when the environment variable

57

54

``BZR_PROGRESS_BAR`` is set to ``none``.

content plus the size of the compressed text. Related to bug #109114.

* Repositories using CHK pages (which includes the new 2a format) will no

67

longer error during commit or push operations when an autopack operation

68

is triggered. (Robert Collins, #365615)

69

63

* Stacking will no longer accept requests to stack on the same

71

64

branch/repository. Existing branches that incorrectly reference the same

72

65

repository in a stacking configuration will now raise

80

73

* Progress bars no longer show the network transport scheme or direction.

86

* ``chk_map.iter_interesting_nodes`` now properly uses the *intersection*

87

of referenced nodes rather than the *union* to determine what

88

uninteresting pages we still need to look at. Prior to this,

89

incrementally pushing to stacked branch would push the minimal data, but

90

fetching everything would request extra texts. There are some unhandled

91

cases wrt trees of different depths, but this fixes the common cases.

(Robert Collins, John Arbash Meinel, #390563)

80

* Command lookup has had hooks added. ``bzrlib.Command.hooks`` has

95

81

three new hook points: ``get_command``, ``get_missing_command`` and

96

82

``list_commands``, which allow just-in-time command name provision

104

90

for files with long ancestry and 'cherrypicked' changes.)

* ``GroupCompress`` repositories now take advantage of the pack hints

108

parameter to permit cross-format fetching to incrementally pack the

109

converted data. (Robert Collins)

110

111

93

* OS file locks are now taken out using ``CreateFile`` rather than

112

94

``LockFileEx`` on Windows. The locking remains exclusive with

113

95

``LockFileEx`` but now it also works on older versions of Windows (such

118

100

properly fetch the minimum number of texts for non-smart fetching.

120

102

121

* ``Repository.commit_write_group`` now returns opaque data about what

122

was committed, for passing to the ``Repository.pack``. Repositories

123

without atomic commits will still return None. (Robert Collins)

124

125

* ``Repository.pack`` now takes an optional ``hint`` parameter

126

which will support doing partial packs for repositories that can do

127

that. (Robert Collins)

128

129

* RepositoryFormat has a new attribute 'pack_compresses' which is True

130

when doing a pack operation changes the compression of content in the

131

repository. (Robert Collins)

132

133

* ``StreamSink`` and ``InterDifferingSerialiser`` will call

134

``Repository.pack`` with the hint returned by

135

``Repository.commit_write_group`` if the formats were different and the

136

repository can increase compression by doing a pack operation.

137

(Robert Collins, #376748)

139

104

* ``VersionedFiles._add_text`` is a new api that lets us insert text into

140

105

the repository as a single string, rather than a list of lines. This can

177

142

this class and the UI. (Martin Pool)

#####################

148

End user testing of the 2a format revealed two serious bugs. The first,

149

#365615, caused bzr to raise AbsentContentFactory errors when autopacking.

150

This meant that commits or pushes to 2a-format repositories failed

151

intermittently.

152

153

The second bug, #390563, caused the smart server to raise AbsentContentFactory

154

when streaming 2a stacked 2a-format branches. This particularly affected

155

branches stored on Launchpad in the 2a format.

156

157

Both of these bugs cause command failures only, neither of them cause data

158

corruption or data loss. And, of course, both of these bugs are now fixed.
