:2.3b1: NOT RELEASED YET

42

:2.3b1: 2010-09-20

43

44

This is the first beta of the 2.3 series, leading up to a 2.3.0

45

release in January or February. Beta releases are suitable for everyday use

46

but may cause some incompatibilities with plugins. Some plugins may need

47

small updates to work with 2.3b1.

48

49

2.3b1 includes some performance improvements in both speed and memory

50

consumption, some preliminary support for generating a texinfo version of

51

the doc and better support for launchpad. Many changes were made to make

52

our test suite more robust as well as numerous documentation fixes. It

53

improves the common infrastructure for dealing with colocated named

54

branches and foreign branches. We plan to continue with these themes

55

through the 2.3 series.

56

57

It also includes bug fixes for 2.0.6, 2.1.3 and 2.2.1 and over 40 fixes of

58

its own.

20

67

is now named "msg" instead of earlier "message".

21

68

(Parth Malwankar, #603461)

22

69

70

* Additional merges after an unrelated branch has been merged with its

71

history no longer crash when deleted files are involved.

72

(Vincent Ladeuil, John Arbash Meinel, #375898)

73

74

* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a

75

previously-unversioned directory within the tree: the directory is

76

marked versioned too.

77

(Martin Pool, #192859)

78

79

* ``bzr commit SYMLINK`` now works, rather than trying to commit the

80

target of the symlink.

81

(Martin Pool, John Arbash Meinel, #128562)

82

83

* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same

84

permissions as ``.bzr`` directory on a POSIX OS.

85

(Parth Malwankar, #262450)

86

23

87

* ``bzrlib.transform.TreeTransformBase.final_kind``,

24

88

``bzrlib.transform.TreeTransform.tree_kind`` and

25

89

``bzrlib.transform.TransformPreview.tree_kind`` now return None instead

26

90

of raising NoSuchFile. (Vincent Ladeuil)

27

91

28

* `decode` parameter to get() method in FtpTransport and GioTransport classes

29

is deprecated. (Alexander Belchenko)

30

31

* `FileInWrongBranch` is deprecated in favour of `PathNotChild` and no

32

longer raised.

33

(Martin Pool)

34

35

* `tree_files` and `internal_tree_files` are now deprecated in favor of

36

`WorkingTree.open_containing_paths`.

37

(Martin Pool)

92

* CommitBuilder now uses the committer instead of _config.username to generate

93

the revision-id. (Aaron Bentley, #614404)

94

95

* Configuration files in ``${BZR_HOME}`` are now written in an atomic

96

way which should help avoid problems with concurrent writers.

97

(Vincent Ladeuil, #525571)

38

98

39

99

* `ControlDirFormat` and `ControlDir` have been split out of `BzrDirFormat`

40

100

and `BzrDir`, respectively. `ControlDirFormat`

60

120

61

121

(Jelmer Vernooij)

62

122

123

* Cope with Microsoft FTP server that returns reply '250 Directory

124

created' when mkdir succeeds. (Martin Pool, #224373)

125

126

* Don't traceback when a lockdir's ``held/info`` file is corrupt (e.g.

127

contains only NUL bytes). Instead warn the user, and allow ``bzr

128

break-lock`` to remove it. (Andrew Bennetts, #619872)

129

130

* `decode` parameter to get() method in FtpTransport and GioTransport classes

131

is deprecated. (Alexander Belchenko)

132

133

* `FileInWrongBranch` is deprecated in favour of `PathNotChild` and no

134

longer raised.

135

(Martin Pool)

136

137

* Fix ``AttributeError on parent.children`` when adding a file under a

138

directory that was a symlink in the previous commit.

139

(Martin Pool, #192859)

140

141

* Fix ``AttributeError: 'NoneType' object has no attribute 'close'`` in

142

``_close_ssh_proc`` when using ``bzr+ssh://``. This was causing

143

connections to pre-1.6 bzr+ssh servers to fail, and causing warnings on

144

stderr in some other circumstances. (Andrew Bennetts, #633745)

145

146

* Only call ``setlocale`` in the bzr startup script on posix systems. This

147

avoids an issue with the newer windows C runtimes used by Python 2.6 and

148

later which can mangle bytestrings printed to the console.

149

(Martin [gz], #631350)

150

151

* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,

152

which can result in "missing referenced chk root keys" errors when

153

fetching from repositories with affected revisions.

154

(Andrew Bennetts, #522637)

155

156

* Raise ValueError instead of a string exception.

157

(John Arbash Meinel, #586926)

158

159

* Reduce peak memory by one copy of compressed text.

160

(John Arbash Meinel, #566940)

161

162

* Repositories accessed via a smart server now reject being stacked on a

163

repository in an incompatible format, as is the case when accessing them

164

via other methods. This was causing fetches from those repositories via

165

a smart server (e.g. using ``bzr branch``) to receive invalid data.

166

(Andrew Bennetts, #562380)

167

168

* Selftest with versions of subunit that support ``stopTestRun`` will no longer

169

error. This error was caused by 2.0 not being updated when upstream

170

python merged the end of run patch, which chose ``stopTestRun`` rather than

171

``done``. (Robert Collins, #571437)

172

173

* Stop ``AttributeError: 'module' object has no attribute 'ElementTree'``

174

being thrown from ``xml_serializer`` on certain cElementTree setups.

175

(Martin [gz], #254278)

176

63

177

* The old ``bzr selftest --benchmark`` option has been removed.

64

178

<https://launchpad.net/bzr-usertest> is an actively-maintained

65

179

macrobenchmark suite.

66

180

(Martin Pool)

67

181

182

* `tree_files` and `internal_tree_files` are now deprecated in favor of

183

`WorkingTree.open_containing_paths`.

184

(Martin Pool)

185

186

* Upgrading or fetching from a non-rich-root repository to a rich-root

187

repository (e.g. from pack-0.92 to 2a) no longer fails with

188

``'Inter1and2Helper' object has no attribute 'source_repo'``. This was

189

a regression from Bazaar 2.1. (Andrew Bennetts, #636930)

190

191

* When passing a file to ``UTF8DirReader`` make sure to close the current

192

directory file handle after the chdir fails. Otherwise when passing many

193

filenames into a command line ``bzr status`` we would leak descriptors.
