f02da4369319 assumed that walkchangerevs called prep with all relevant matched
filenames, but actually it only contains the names of files changed in the
relevant changeset. That meant that log diff/stat of merges missed the diff for
files only changed in the other branch.
This is a minimal fix for making sure we only use fns when we are following and
thus will have problems with merges anyway ...
As with push, the optional destination path is ignored for the
subrepositories, i.e., they are always compared with their default
push path. Fixing this is Issue1852.
This removes the warn() function in favor of issuing warnings directly
for each kind of file that Mercurial won't remove.
This also uses three separate translatable strings instead of using
string formatting to build the message. This should make it easier to
localize.
If a repository is accesible, first treat the filename as a working copy file
and try to open its filelog. Fallback to opening the file directly as a
revlog, as before.

Currently, a number of commands and help topics mention the user hgrc
file in different ways. Among these are following:
1. .hgrc - "please specify your commit editor/username in your .hgrc
file", bookmarks, color, hgk, pager, hg help environment
2. $HOME/.hgrc - hg help paths, hgrc(5), hg(1)
3. ~/.hgrc - hgrc(5)
In addition to being inconsistent, none of these make sense on
Windows. This patch replaces the above with a more general term of
"[your] configuration file".
This adds util.getport(port) which tries to parse port as an int, and
failing that, looks it up using socket.getservbyname(). Thus, the
following will work:
[smtp]
port = submission
[web]
port = http
This does not apply to ports in URLs used in clone, pull, etc.
This commit updates the branches command to use ui.label for the branch names
and the changeset. This implementation allows assigning colors to the four
states of a branch: active, closed, current and inactive. While you can
configure color for the four states, only current and closed have default colors
of green and black bold respectively.
If you want to programatically perform a revert right now you need to
include a date=False parameter due to the use of opt["date"] instead
of opt.get("date").
When addbranchrevs extends revs, it adds changeset hashes, and not node ids.
Which means that we have to lookup for revisions _after_ the addbranchrevs
call, instead of before.
By renaming before reverting the content of the file we ensure that we handle
and break hardlinks properly.
Handling of other hardlinks to .orig is somebody elses problem.
Branches can have multiple heads, so it doesn't make sense to speak of "the
head of the current branch". What update really does is try to update to the
*tip* of the current branch.
Some encoding and language combinations (e.g.: UTF-8 and Japanese)
cause encoding characters into sequence of bytes more than column
width of them.
So, encoding.colwidth() should be applied instread of len() on i18n
strings.
In addition to it, formatting by '%*s'/'%-*s' also uses "number of
bytes" to calculate space padding size, and should be fixed, too.
This patch adds git-style "shell aliases" to Mercurial.
Any alias with a definition beginning with a '!' will be treated as a shell
alias. For example:
[alias]
echo = !echo
qempty = !hg qrefresh -X "`hg root`" ; echo Emptied patch "`hg qtop`"
$ hg echo foo
foo
$ hg qempty
Emptied patch foo
$
When commiting, a check is made to see if one of the parents is a
closed head. However this did not check that the branch of the commit
is the same as the closed head, so one could get a warning message on
the sequence
hg commit --close-branch
hg branch new-branch
hg commit
or when merging in a closed head.
In commands.log a displayer was initialized from
cmdutil.show_changeset() with the initial matchfn (which designates
the specified files which only is correct in the highest revision in
the range). prep() is handed the correct list of files, but
displayer.show() didn't use that list but keept using the original
matchfn.
The matchfn argument to cmdutil.show_changeset() wasn't specified in
other places and is only used in .show(), so now we give the matchfn
as an optional parameter to .show().
We do however still have to detect --patch and --stat from opts in
show_changeset() and let it imply a matchall, but that can now be
overruled with the new .show() matchfn parameter.
Currently, callers of addchangegroup first acquire the repository
lock, usually to check that an unbundle request isn't racing. This
means that changegroup hook actions that might write to a repo get
stuck waiting for a lock. Here, we add a new optional lock parameter
and update all the callers. Post-1.6 we may make it non-optional.
Currently merge just prints abort-like messages to stderr and then
exits with a misleading status 0 (cleverly disguised as "False").
With this change it raises Abort, just like every other fatal error.
Useful in tests to quickly build a complex DAG in an empty repo.
Handles local tags and named branches.
Options to, at each rev,
- create a new file,
- overwrite the same file,
- append to the same file,
- write to a specific line in a mergeable file.
Can run shell commands during DAG buildup.
Mainly useful for reusing DAGs somewhere else, for example for attaching
them to a bug report, or for importing them into other environments
(like my test environment for incoming/outgoing discovery).
this helps users to know what kind of option is:
- no value is required(flag option)
- value is required
- value is required, and multiple occurrences are allowed
each kinds are shown as below:
-f --force force push
-e --ssh CMD specify ssh command to use
-b --branch BRANCH [+] a specific branch you would like to push
if one or more 3rd type options are shown, explanation for '[+]' mark
is also shown as footnote.
To avoid recurrent fixes for the display of this message, a summary table with
all case combinations has been added to the code.
Basically, there is two condition for the message to be printed:
* this is not an initial (named branch or topo) root
* none of the parents are in the current branch heads
Some implementations of ui.label() (HTML versions in particular) must escape
the provided text and then markup the text with their tags. When this marked
up text is then passed to ui.write(), we must label the text as 'ui.labeled'
so the implementation knows not to escape it a second time (exposing the initial
markup).
This required the addition of a 'ui.plain' label for text that is purposefully
not marked up.
I was a little pedantic here, passing even ' ' strings to ui.label() when it
would be included with other labeled text in a ui.write() call. But it seemed
appropriate to lean to the side of caution.
Mercurial has problem around text wrapping/filling in MBCS encoding
environment, because standard 'textwrap' module of Python can not
treat it correctly. It splits byte sequence for one character into two
lines.
According to unicode specification, "east asian width" classifies
characters into:
W(ide), N(arrow), F(ull-width), H(alf-width), A(mbiguous)
W/N/F/H can be always recognized as 2/1/2/1 bytes in byte sequence,
but 'A' can not. Size of 'A' depends on language in which it is used.
Unicode specification says:
If the context(= language) cannot be established reliably they
should be treated as narrow characters by default
but many of class 'A' characters are full-width, at least, in Japanese
environment.
So, this patch treats class 'A' characters as full-width always for
safety wrapping.
This patch focuses only on MBCS safe-ness, not on writing/printing
rule strict wrapping for each languages
MBCS sensitive textwrap class is originally implemented
by ITO Nobuaki <daydream.trippers@gmail.com>.
Compare this to --force which allows anything to be pushed. With --new-branch,
only changesets to named branches not present on the and changesets not
introducing additional heads on existing branches are allowed.

This is in preparation for generaldelta, where the revlog entry base field is
reinterpreted as the deltaparent. For that reason we also rename the base
function to chainbase.
Without generaldelta, performance is unaffected, but generaldelta will suffer
from this in _addrevision, since delta chains will be walked repeatedly.
A cache has been added to eliminate this problem completely.
discovery.findoutgoing used to be a useful hook for extensions like
hgsubversion. This patch reintroduces this version of findcommonincoming
which is meant to be used when computing outgoing changesets.
The Mercurial 1.9 release is moving a lot of stuff around anyway and we are
already moving path_auditor from util.py to scmutil.py for that release.
So this seems like a good opportunity to do such a rename. It also strengthens
the current project policy to avoid underbars in names.
Adds a -i/--inactive flag to the bookmarks command to create or move a
bookmark without making it the current one. This lets you use a bookmark
like a shareable, movable 'tag' and less like a 'branch'.
Thanks to Alexander Solovyov <alexander@solovyov.net> for most of the
work of implementation, and Matt Mackall <mpm@selenic.com> for
suggesting the option name.
These leaks may occur in environments that don't employ a reference
counting GC, i.e. PyPy.
This implies:
- changing opener(...).read() calls to opener.read(...)
- changing opener(...).write() calls to opener.write(...)
- changing open(...).read(...) to util.readfile(...)
- changing open(...).write(...) to util.writefile(...)
Adds a new discovery method based on repeatedly sampling the still
undecided subset of the local node graph to determine the set of nodes
common to both the client and the server.
For small differences between client and server, it uses about the same
or slightly fewer roundtrips than the old tree-based discovery. For
larger differences, it typically reduces the number of roundtrips
drastically (from 150 to 4, for instance).
The old discovery code now lives in treediscovery.py, the new code is
in setdiscovery.py.
Still missing is a hook for extensions to contribute nodes to the
initial sample. For instance, Augie's remotebranches could contribute
the last known state of the server's heads.
Credits for the actual sampler and computing common heads instead of
bases go to Benoit Boissinot.
This drops the options to run arbitrary shell commands within
commits and the option to create a file that gets appended to
in every revision. It now supports to not write file data at
all, which is very fast for generating a pure 00changelog.i
(useful for discovery tests, for instance).
Timings for 1000 linear nodes:
* Old `hg debugbuilddag -o '+1000'` took 4.5 secs.
* New `hg debugbuilddag -o '+1000'` takes 2 secs.
* New `hg debugbuilddag '+1000'` takes 0.8 secs.
(The last one creates only 00changelog.i).
The introduction of the new URL parsing code has created a startup
time regression. This is mainly due to the use of url.hasscheme() in
the ui class. It ends up importing many libraries that the url module
requires.
This fix helps marginally, but if we can get rid of the urllib import
in the URL parser all together, startup time will go back to normal.
perfstartup time before the URL refactoring (707e4b1e8064):
! wall 0.050692 comb 0.000000 user 0.000000 sys 0.000000 (best of 100)
current startup time (9ad1dce9e7f4):
! wall 0.070685 comb 0.000000 user 0.000000 sys 0.000000 (best of 100)
after this change:
! wall 0.064667 comb 0.000000 user 0.000000 sys 0.000000 (best of 100)
This is a long desired cleanup and paves the way for new discovery.
To specify subsets for bundling changes, all code should use the heads
of the desired subset ("heads") and the heads of the common subset
("common") to be excluded from the bundled set. These can be used
revlog.findmissing instead of revlog.nodesbetween.
This fixes an actual bug exposed by the change in test-bundle-r.t
where we try to bundle a changeset while specifying that said changeset
is to be assumed already present in the target. This used to still
bundle the changeset. It no longer does. This is similar to the bugs
fixed by the recent switch to heads/common for incoming/pull.
New argument is silently ignored by both HTTP and SSH servers.
This means we can, for instance, add new flags to getbundle()
to request advanced features (like lightweight-copy-aware bundles),
and older servers will silently ignore this request and send back
a plain bundle.
Example
$ hg clone --jump foo bar
hg clone: option --jump not recognized
hg clone [OPTION]... SOURCE [DEST]
make a copy of an existing repository
options:
-U --noupdate the clone will include an empty working copy (only a
repository)
-u --updaterev REV revision, tag or branch to check out
-r --rev REV [+] include the specified changeset
-b --branch BRANCH [+] clone only the specified branch
--pull use pull protocol to copy metadata
--uncompressed use uncompressed transfer (fast over LAN)
-e --ssh CMD specify ssh command to use
--remotecmd CMD specify hg command to run on the remote side
--insecure do not verify server certificate (ignoring
web.cacerts config)
[+] marked option can be specified multiple times
use "hg help clone" to show the full help text
Motivation for this change
If the user already has specified the command, he probably already knows
the command to some extent. Apparently, he has a problem with the options,
so we show him just the synopsis with the short help and the details about
the options, with a hint on the last line how to get the full help text.
Why is Mercurial better with this change?
Experts who just forgot about the details of an option don't get that
much text thrown at them, while the newbies still get a hint on the last
line how to get the full help text.
Before, you could experience the following strange interaction:
$ hg commit
nothing changed
$ hg merge
abort: outstanding uncommitted changes
which confused at least one user in #mercurial.
_findtags in localrepo checks that nodes exist in the revlog so we
can't get a LookupError here.
The output of 'hg tags' stays the same since tags to unknown nodes
didn't get printed before anyway due to 734bab2916a6.
Pull outputs a slightly new message when there are multiple branches and
the current branch has many heads:
(run 'hg heads .' to see heads, 'hg merge' to merge)
This message adds the "." in hg heads to encourage you to consider only the
current branch's heads.
After a pull when new heads are added but no head is added on the current
branch, the "run 'hg merge'" message can be misleading. This patch doesn't
output the merge message in that scenario.
Why?
- Mercurial internal patcher works correctly for regular patches and git
patches, is much faster at least on Windows and is more extensible.
- In theory, the external patcher can be used to handle exotic patch formats. I
do not know any and have not heard about any such use in years.
- Most patch programs cannot handle git format patches, which makes the API
caller to decide either to ignore ui.patch by calling patch.internalpatch()
directly, or take the risk of random failures with valid inputs.
- One thing a patch program could do Mercurial patcher cannot is applying with
--reverse. Apparently several shelve like extensions try to use that,
including passing the "reverse" option to Mercurial patcher, which has been
removed mid-2009. I never heard anybody complain about that, and would prefer
reimplementing it anyway.
And from the technical perspective:
- The external patcher makes everything harder to maintain and implement. EOL
normalization is not implemented, and I would bet file renames, if supported
by the patcher, are not correctly recorded in the dirstate.
- No tests.
How?
- Remove related documentation
- Clearly mark patch.externalpatch() as private
- Remove the debuginstall check. This deprecation request was actually
triggered by this last point. debuginstall is the only piece of code patching
without a repository. When migrating to an integrated patch() + updatedir()
call, this was really a showstopper, all workarounds were either ugly or
uselessly complicated to implement. If we do not support external patcher
anymore, the debuginstall check is not useful anymore.
- Remove patch.externalpatch() after 1.9 release.
getbundle(common, heads) -> bundle
Returns the changegroup for all ancestors of heads which are not ancestors of common. For both
sets, the heads are included in the set.
Intended to eventually supercede changegroupsubset and changegroup. Uses heads of common region
to exclude unwanted changesets instead of bases of desired region, which is more useful and
easier to implement.
Designed to be extensible with new optional arguments (which will have to be guarded by
corresponding capabilities).
known([Node]) -> [1/0]
Returns 1/0 for each node, indicating whether it's known by the server.
Needed for new discovery protocols introduced in later patches.
