dispatch: fix traceback when extension was tested with newer versions only The "worst" extension still is the one tested with the lowest tested version below the current version of Mercurial, but if an extension with was only tested with newer versions, it is considered a candidate for a bad extension, too. In this case extensions which have been tested with higher versions of Mercurial are considered better. This allows finding the oldest extension if ct can't be calculated correctly and therefore defaults to an empty tuple, and it involves less changes to the comparison logic during the current code freeze.

test-extension.t: use fixed version string instead of current tag Currently tests break with the current tag being 2.3-rc and tags set by the user could affect this test, too.

Added tag 2.3-rc for changeset a06e2681dd17

merge default into stable for 2.3 code freeze

windows: removed duplicate termwidth definition Changeset dbf91976f900 caused this when the "from win32 import *" line was replaced with explicit import statements: the wildcard import was at the bottom of the file and so windows.termwidth was overwritten by win32.termwidth as indented, but the new explicit import statements were at the top and so win32.termwidth got lost. With the switch to ctypes, win32 can always be imported and so the fallback termwidth in windows is no longer needed.

httprepo: ensure Content-Type header exists when pushing data Otherwise the wireprotocol just hangs while trying to send data. (And nothing is received at the other side)

obsolete: obsstore.add now takes a list of markers. This allow efficient IO and it greatly simplify the merging of markers.

obsolete: refactor writemarkers to only encode them The function is now able to write the version header as necessary. The function now yield bytes to be written to a stream. This should ease later use of this function for wireprotocol based exchanged. Prepare the public use of the writemarker by wireprotocol function.
