incoming: unify code for incoming and graphlog.incoming

incoming: rename variable Groundwork so that incoming and graphlog.incoming code look the same and get easier to unify.

import: only the first hg patch marker should be processed (issue2417) Proper use of the hgpatch state variable had been lost in the final edits of d7452292f9d3 - now it works more like intended.

backout: provide linear backout as a default (without --merge option) This changes backouts changeset to retain linear history, .e. it is committed as a child of the working directory parent, not the reverted changeset parent. The default behavior was previously to just commit a reverted change as a child of the backed out changeset - thus creating a new head. Most of the time, you would use the --merge option, as it does not make sense to keep this dangling head as is. The previous behavior could be obtained by using 'hg update --clean .' after a 'hg backout --merge'. The --merge option itself is not affected by this change. There is also still an autocommit of the backout if a merge is not needed, i.e. in case the backout is the parent of the working directory. Previously we had (pwd = parent of the working directory): pwd older backout auto merge backout --merge auto commit With the new linear approach: pwd older backout auto commit backout --merge auto commit auto: commit done by the backout command merge: backout also already committed but explicit merge and commit needed commit: user need to commit the update/merge

update: use revsingle to enable use of revsets as update targets (issue1993)

test-url: skip test when ssl module is unavailable

test-url: remove trailing whitespace

keyword: code cleanup - move preselection of expansion candidates for rollback and record into helper function - same overwrite order in rollback and record: 1. modified, 2. added - self.wlock() inside kwrepo class instead of repo.wlock()

tests: asciify output of test-encoding-align.t

tests: accept \-escaped test output It changes tsttest to accept expected outputs in python-style \-escapes. It aims to avoid trouble with outputs for non-ascii, color and progress tests.

parentdelta: compress.py extension is no longer necessary Using `hg --config format.parentdelta=True clone --pull src dst` is equivalent.

convert/darcs: support changelogs with bytes 0x7F-0xFF (issue2411) This is a followup to 4481f8a93c7a, which only fixed the conversion of patches with UTF-8 metadata. This patch allows a changelog to have any bytes with values 0x7F-0xFF. It parses the XML changelog as Latin-1 and uses converter_source.recode() to decode the data as UTF-8/Latin-1. Caveats: - Since the convert extension doesn't provide any way to specify the source encoding, users are still limited to UTF-8 and Latin-1. - etree will still complain if the changelog has bytes with values 0x00-0x19. XML only allows printable characters.

revset: add id() and rev() to allow explicitly referring to changes by hash or rev

revset: rename tagged() to tag() and allow it to take an optional tag name

bookmarks: add revset for referencing bookmarks

hgweb help: fix double help links

tests: add testcase for --config format.dotencode=false

fetch: fix and document exit codes (issue2356)

doc: add [format] dotencode description

filectx: use ctx.size comparisons to speed up ctx.cmp Comparing sizes is cheaper than comparing file contents, as it does not involve reading the file on disk or from the filelog. It is however not always possible: some extensions, or encode filters, change data when extracting it to the working directory.

localrepo: use propertycaches to access encode/decode filters

localrepo: load filter patterns outside of _filter
