Based on a patch by Fuming Wang
- add util.binary which decides whether a file is binary if it has any NUL
characters in the first 1K.
- teach mdiff.unidiff to print "binary file <x> has changed" for binary files
- add text flag to cause unidiff and dodiff to treat all files as text
- add -a and --text flags (like diff(1)) to hg diff and export
- update docs
- rename mode to branch_merge
- use explicit update mode
- use negative mtime for updates that set mtime
- expand some cryptic variable names
- elaborate merge dirstate comments
- remove redundant manifest lookup for non-merge case
- remove impossible merge case
- fix up test cases
- use new changed list to track what files actually got new revlog entries
at commit/rawcommit time
- when updating a file during a merge, don't mark it as completely unchanged
- handle file not being in parent 1 in status
Since switching to the multihead approach, we've been creating
excessive file-level merges where files are marked as merged with
their ancestors.
This explicitly checks at commit time whether the two parent versions
are linearly related, and if so, reduces the file check-in to a
non-merge. Then the file is compared against the remaining parent,
and, if equal, skips check-in of that file (as it's not changed).
Since we're not checking in all files that were different between
versions, we no longer need to mark so many files for merge. This
removes most of the 'm' state marking as well.
Finally, it is possible to do a tree-level merge with no file-level
changes. This will happen if one user changes file A and another
changes file B. Thus, if we have have two parents, we allow commit to
proceed even if there are no file-level changes.
- allow passing a repo object instead of a path
(if we get a string, we construct a repo object)
- hg serve: pass options via repo.ui.setconfig
- add --style option
- get default name from repo.root rather than getcwd()
- remove template argument to hgweb()
- reduce create_server from 8 args to 1
Right now, mercurial doesn't take daylight saving time into account
because it uses time.timezone inconditionally, instead of resorting to
time.altzone if daylight saving time is on.
Example:
% hg log | head -12

This merges a bunch of the ideas for a multi-repository CGI script and
simplifies things a bit.
It uses PATH_INFO so it generally wants paths of the form:
http://host/hg.cgi/virtualpath
This gets mapped via a simple config file to the real path. All info
about the repo is read from the repo's hgrc.
Most read operations in hg don't need locks because we order reads and
writes for consistency. Clone is an exception to this as we're copying
entire file histories and could end up with more file history copied
than we have commits.
For now, make clone take a lock on the source repo. Non-hardlinked
clone should eventually be changed to use lockless pull.
named branching is when you identify a head by a tag on an earlier revision.
This patch adds repo.branchlookup for searching through the tree to
find branch tags for heads.
hg update -b tag is added to checkout based on branch tags
hg heads -b is added to print the tag associated with each head
Temporary fix to allow Mercurial to build on HP-UX 11, as the C
compiler on HP-UX 11 doesn't support 'inline' qualifier. The
'__inline' qualifier seemed to be supported, but not without
first resolving other associated issues.
Prior to this, a file that did not exist was reported as showing up in
the filesystem, as were files of unsupported types (such as fifos).
Now, an error message is printed and nothing is returned in such cases.
This change also moves the commands.pathto function to the util module,
as the walk code needs it to print non-confusing error messages.
a list of files to look at. These end up with a src of 'f' from
walk() but no longer exist on the filesystem.

===================================================================
The repo walking code introduces a number of calls to dirstate.map.copy(),
significantly slowing down the walk on large trees. When a list of
files is passed to the walking code, we should only look at map entries
relevant to the file list passed in.
dirstate.filterfiles() is added to return a subset of the dirstate map.
The subset includes in files passed in, and if one of the files requested
is actually a directory, it includes any files inside that directory tree.
This brings the time for hg diff Makefile down from 1.7s to .3s on
a linux kernel repo.
Also, the diff command was unconditionally calling makewalk, leading
to an extra pass through repo.changes. This patch avoids the call
to makewalk when commands.diff isn't given a list of patterns, cutting
the time for hg diff (with no args) in half.

===================================================================
The dirstate has to match what is in the repository (what would be
checked out with 'hg update -C'), because the resulting file may be
identical to the new parent, or it may be completely different.
Previously the dirstate wasn't updated, so if you changed the file to
look like the original parent, it might be considered unmodified
relative to the new parent.
On the other OS, it seems that case insensitivity for
environment vars can bite users when using some unknown
combination of python 2.4.1 and win2kSP4+minsys (and
probably other vversions of these softwares).
The best way to avoid problems in those weird cases is to
ignore OSError exception during env var deletion.
Interface is not yet changed.
Non-regular files are considered to be removed or deleted.
Removed the unneeded match(fn) call for adding to the unknown list.
