largefiles: fix a traceback when addremove follows a remove (issue3507) The problem only occurred if a file was removed with 'hg rm' (as opposed to the OS utilities), and then addremove was run before a commit. Both normal and large files were affected. Ensuring that the file exists prior to an lstat() for size seems like the Right Thing. But oddly enough, the missing file that was causing lstat() to blow up was a standin when a largefile was removed, which seems fishy, because a standin should never be added as a largefile. I was then able to get a standin added as a largefile (whose name is 'large') with hg addremove --config largefiles.patterns=**large which also causes a backtrace. That will be fixed next.

largefiles: defer lfdirstate.drop() until after commit (issue3364) The example in comment #9 of the bug writeup must be run exactly- it was the commit after the rm and prior to the addremove that screwed things up, because that commit noticed that the largefile was missing, called drop(), and then the original commit function did nothing (due to the file in the '!' state). The addremove command properly put it into the 'R' state, but it remained stuck in that state (because commit insisted 'nothing changed'). Without the commit prior to addremove, the problem didn't occur. Maybe this is an indication that lfdirstate needs to take a few more hints from the regular dirstate, regardless of what _it_ thinks the state is- similar inconsistency is probably still possible with this patch if the original commit succeeds but the lfdirstate write fails.

largefiles: fix addremove with -R option If a file was missing, the missing list contained a path relative to the repo. When building the matcher from that list, the file name ended up concatenated to cwd, causing the command to abort with '<file> not under root'. This rebuilds the missing list with paths relative to cwd.

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

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.

update: put rules for uncommitted changes into verbose help section

hooks: print out more information when loading a python hook fails When loading a python hook with file syntax fails, there is no information that this happened while loading a hook. When the python file does not exist even the file name is not printed. (Only that a file is missing.) This patch adds this information and a test for loading a non existing file and a directory not being a python module.

perf: fix perfcca to work with new casecollisionauditor interface A recent changeset, afd75476939e, modified the caescollisionauditor interface but did not update perf.py. This changeset remidies that.

checkheads: extract branchmap preprocessing The checkheads function is far too complicated. This extract help to explicite what part of the preprocessing are reused by the actual check. This the first step toward a wider refactoring.

checkheads: take future obsoleted heads into account If we push some successors they will likely create a new head on remote. However as the obsoleted head will disappear after the push we are not really increasing the number of heads. There is several case which will lead to extra being actually pushed. But this first changeset aims to be simple. See the inline comment for details. Without this change, you need to push --force every time you want to push a newer version which is very error prone. The remote side still display +n heads on unbundle because it does not have the obsolete marker at unbundle time.

obsolete: add an any successors function This function yield every nodes which succeed to a group of nodes. The first user will be checkheads who need to know if we push successors for remote extra heads.

checkheads: extract bookmark computation from the branch loop No branch specific data are used in the computation of the bookmarked heads. We can only compute it once.

checkheads: simplify the structure build by preprocessing All useful data are now gathered in a single dictionnary. `branchmapsummary` is renamed to `headssummary` and its return value is greatly simplified.

_updatebranchcache: prevent deleting dict key during iteration We use dict.keys() to fetch all keys before starting to delete some. Otherwise python complains that the dictionnary is altered during iteration.

checkheads: extract branchmap preprocessing The checkheads function is far too complicated. This extract help to explicite what part of the preprocessing are reused by the actual check. This the first step toward a wider refactoring.

obsolete: mark unreachable extinct changesets as hidden The repo.hiddenrevs set is updated with all extinct() changesets which aren't descendants of either: - the current working copy, - a bookmark, - a tag.
