The default of pushing all largefiles referenced in outgoing revisions is safe,
but also expensive and sometimes not what is needed. We thus introduce a
--lfrev option, similar to what pull already has.
By specifying an empty set of revisions (or null), it is possible to get lazy
(and insecure!) pushes of revisions without referenced largefiles, similar to
how pull works.
prepushoutgoinghook was introduced in 8dfcd476a7f7 and largefiles is the only
in-tree use of it. Refactor it to be more useful for other use cases in
largefiles.
Before this patch, extensions expecting a different random state per command
will break since the chg request handler will inherit a same random state
from the parent daemon process.
This patch addresses the issue by calling random.seed() after fork.
Before this patch, if the server address is long, the server will fail to
listen and throw the error:
socket.error: AF_UNIX path too long
It is because AF_UNIX path usually has a very short length limit (107 chars on
common platforms, see sys/un.h).
This patch addresses the issue by using relative path instead. Therefore the
directory length does not matter. It helps run tests with chg using a long
$TMPDIR.
A previous patch moved it to an incorrect place. Since dispatch._earlygetopt
has side effects on args, we need to move it to the place before _earlygetopt.
This commit is part of bigger effort described in 'Windows UTF-8' plan.
It is not changing all invocations but the ones where change is
obviously correct and doesn't require complicated changes.
Before this patch, rebase --continue would crash when trying to resume a rebase
of obsolete revisions whose successors were in the destination.
This patch adds logic to recompute the mapping when rebase is resumed. This
patch also adds a test that showcased the crash before the code change.
This patch extracts the error handling code path to go in a separate function.
In the next patch we will able to reuse this logic and avoid duplicated code.
writebundle() writes a bundle2 bundle or a plain changegroup1. Imagine
away the "2" in "bundle2.py" for a moment and this change should makes
sense. The bundle wraps the changegroup, so it makes sense that it
knows about it. Another sign that this is correct is that the delayed
import of bundle2 in changegroup goes away.
I'll leave it for another time to remove the "2" in "bundle2.py"
(alternatively, extract a new bundle.py from it).
When code like filemerge._iprompt calls ui.prompt, it expects
the user to see the output in addition to getting the prompt.
Other code such as histedit may call ui.pushbuffer, but its
goal is not to interfere with prompts, so this commit adds
an optional prompt flag to ui.write and has _readline
include that argument.
ui.promptchoice calls ui.prompt which calls ui._readline.
This commit also updates hgext.color.write.
SyntaxError is the class representing syntax errors in Python code. We should
use a dedicated exception class for our needs. With this change, unnecessary
re-wrapping of SyntaxError can be eliminated.
Super long first line in description lead to very long file name that
windows is unhappy about. We restrict the name to 75 char to avoid the
issue.
75 seems fine and leave some extra room for '__#' suffix in case of conflict.
I does not seems worthwhile to add a dedicated config option to configure the
length. It can be done in the future if there is an actual user demand for it.
Before this patch, deprecated options below are used in synopsis of
command help, even though they aren't listed up as available options
by default. These might confuse readers.
- -n (no-op, now) of strip
- -a/--active of branches
- -f/--force of merge
cf6cc5344afa added 'ignoresub' argument to ui.configitems(), but zeroconf
wrapper wasn't updated. It caused the following crash:

We have no test coverage for zeroconf, so I've added a minimal test that
could reproduce this problem.
Rather than look for the lowest revision, see if the rebase state is tracking
the parents of this revision. Otherwise we can't handle multiple revisions in
one rebase that includes a merge revision.
Fixes issue5044.
This patch fixes problems below:
- ":hg:" role should be followed by not '"' but '`'
- there is a help topic not "default-push" but "config.default-push"
Previously, if the largefile was deleted at the time of a commit, the standin
was silently not updated and its current state (possibly garbage) was recorded.
The test makes it look like this is somewhat of an edge case, but the same thing
happens when an `hg revert` followed by `rm` changes the standin.
Aside from the second invocation of this in lfutil.updatestandinsbymatch()
(which is what triggers this test case), the three other uses are guarded by
dirstate checks for added or modified, or an existence check in the filesystem.
So aborting in lfutil.updatestandins() should be safe, and will avoid silent
skips in the future if this is used elsewhere.
The change in 6fce9a02f069 to handle a normal -> largefile switch was too
aggressive in preserving the original matcher names. If a largefile is
explicitly provided by the user, but only the standin exists in dirstate, then
only the standin can be committed.
There's still maybe an issue when the largefile is deleted outside of Mercurial:
$ rm large
$ hg ci -m "oops" large
large: The system cannot find the file specified
nothing changed
[1]
Before this patch, although chgserver drops repo object by setting it to None,
there is another side effect loading a repo: setting bundle.mainreporoot.
This patch explicitly sets it to empty to undo the side effect. It will make
chg pass test-strip.t.
It's been superseded by config/env hash. A log message is simplified as we no
longer need a diff of environment variables. Also, _loadnewui() is changed to
require args since it can't copy old --config values without args.
Before this patch, chgserver will use repo ui as dispatch.request.ui, while
req.ui is designed to be global ui without repo config.
Passing repo ui as dispatch.request.ui leads to repo.ui being incorrect, which
can lead to unwanted results. For example, if the repo config has [extensions],
it could affect which localrepository.featuresetupfuncs get executed and the
repo may have an incorrect list of supported requirements.
This patch changes _renewui to return both global ui and repo ui. The global
ui is passed to req.ui, and the repo ui is used to calculate confighash. It
will make chg pass test-largefiles-misc.t and test-requires.t, which are both
related to repo requirements.
Adds a hint to histedit comment reminding user about enabled dropmissing.
This will make the enabled dropmissing more visible. The example comment:
# Edit history between 5abd0a5c28d1 and b54649a8a63f
#
# Commits are listed from least to most recent
#
# You can reorder changesets by reordering the lines
#
# Commands:
#
# e, edit = use commit, but stop for amending
# m, mess = edit commit message without changing commit content
# p, pick = use commit
# b, base = checkout changeset and apply further changesets from there
# d, drop = remove commit from history
# f, fold = use commit, but combine it with the one above
# r, roll = like fold, but discard this commit's description
#
# Deleting a changeset from the list will DISCARD it from the edited history!
Before this patch, chgui will override the system method, forwarding every
process execution to the client so sessions and process groups can work as
expected. But the chg client will just use stdout, if ui.fout is not stdout or
if the output is set to be captured to safe._buffers, the client will not
behave correctly.
This can happen especially with code prepending "remote:". For example, bundle2
uses ui.pushbuffer, and sshpeer sets fout to ferr. We may have trouble with
interactive commands in the fout set to ferr case but if it really bites us, we
can always send file descriptors to the client.
This patch adds a check to detect the above situations and fallback to the old
ui.system if so. It will make chg happy with test-bundle2-exchange.t,
test-phases-exchange.t, test-ssh-bundle1.t and test-ssh.t.
9f1a3c7b4a28 introduced support for not having a "global" user cache.
In the rare cases where the environment didn't provide the location of the
current home directory, the usercachepath function could return None.
That functionality has since bitrotten and several code paths did not correctly
check for usercachepath returning None:
$ HOME= XDG_CACHE_HOME= hg up --config extensions.largefiles=
getting changed largefiles
abort: unknown largefiles usercache location
Dropping the partial support for it is thus not really a backward compatibility
breaking change.
Thus: consistently fail early if the usercache location is unknown.
It is relevant to be able to control where the largefiles are stored and how
they propagate, but that should probably be done differently. The dysfunctional
code just gets in the way.
Before this patch shelve never preserved branch information,
so after applying unshelve branch was the same as it was
on working copy no matter in which branch shelve took place.
This patch makes bare shelving(with no files specified, without
interactive,include and exclude option) remembers information if
the working directory was on newly created branch ,in other words
working directory was on different branch than its first parent.
In this situation unshelving restores branch information to the working
directory.
This patch prepares for restoring newly created branch only on
bare shelve later because information about new-branch will be
preserved only when shelve was bare and working copy branch
was different than branch of its parent. In other case information
about new-branch will be gone, so unshelve will not recognise that
shelve was made on new-branch and it will not restore branch
information from the bundle to the working directory.
Replaces invocations os.path functions to methods in vfs. Unfortunately
(in my view) this makes code less readable, because instead of using
clear variable names with path it needs to replace them with vfs(..).
I need guidance how to make such transition look more readable.
For example in this patch there is example with few places with
wvfs.join(standindir), standindir before this patch was absolute
path, in this it is changed to relative because it is used also
in expression wvfs.join(standindir, pat).
chg has its own pager implementation that it wants to skip pager's uisetup.
It is currently done by redirecting stdout to /dev/null, which has unintended
side effects. This patch makes pager aware of chg and skip uisetup directly
from pager. We may want to merge chg and pager's pager implementation to
make this unnecessary in the future.
SocketServer.ForkingMixIn uses os._exit which will skip all cleanup handlers.
We want to run __del__ to make things like transactions, {ssh,http}peer,
atomictempfile, dirstateguard, etc. work.
This patch adds a "gc.collect()" to trigger __del__. It is helpful for chg
to pass some test cases in test-devel-warnings.t.
It's possible for the blackboxui code to do a "del self._bbvfs", then ui.copy()
or similar attempt will fail. It will also fail when constructing a blackboxui
from a non-blackbox ui.
This patch fixes the issue by not assuming any _bb* attr is set.
Closing stdin is unexpected by chgserver and is not a good idea generally.
This patch refactors related code a bit and make sure stdin is not closed.
It will make chg much happier on test-histedit*.t.
The current chgserver design is to use one server to handle multiple repos
which has same [extensions] config. Previously the client uses --cwd / to
avoid creating a repo object. Now we need to set repo to None before we
have code to make "serve" command norepo when it's chg.
Previously, if extensions fail to load, chg server will just keep working
without those extensions. It will print a warning message but only if a new
server starts.
This patch invalidates the server if any extension failed to load, but still
serve the client (hopefully just) once. It will help chg pass some test cases
of test-bad-extension.t.
In some rare cases (next patch), we may want validate to do "unlink" without
forcing the client reconnect. This patch addes a new "reconnect" instruction
and makes "unlink" not to reconnect by default.
Visual C/C++ 9, which Python 2.7 is compatible with, doesn't have C99
support and thus doesn't contain a stdint.h file.
This changeset adds a custom version of stdint.h, created specifically
for Visual C, and uses it when building with that compiler.
We noticed that many users have the intuition of laving the editor empty when
they want to abort the operation. The fact that dropmissing allows user to
delete all edited commits is not intuitive even for users that asked for it.
Let's prevent people from this footgun.
Currently the validate command in chgserver expects config can be loaded
without issues but the config can be broken and chg will print a stacktrace
instead of the parsing error, if a chg server is already running.
This patch adds a handler for ParseError in validate and a new instruction
"exit" to make the client exit without abortmsg. A test is also added to make
sure it will behave as expected.
The chgserver may have a different cwd from the client because of the side
effect of "--cwd" and other possible os.chdir done by extensions. Therefore
relative paths can be misunderstood by the client.
This patch solves it by expanding relative cwd path to absolute one before
sending them via the 'S' channel. It can help chg to pass a testcase in
test-alias.t later.
In 'unix' mode, the server is typically detached from the console. Therefore
a client couldn't see the exception that occurred while instantiating the
server object.
This patch tries to catch the early error and send it to 'e' channel even if
the server isn't instantiated yet. This means the error may be sent before the
initial hello message. So it's up to the client implementation whether to
handle the early error message or error out as protocol violation.
The error handling code is also copied to chgserver.py. I'll factor out them
later if we manage to get chg passes the test suite.
00820e3ad90f (zeroconf: remove camelcase in identifiers, 2016-03-01)
forgot one occurrence of "numAuthorities", which makes test-paths.t
fail for me. I don't even know what zeroconf is, but this patch seems
obviously correct and it fixes the failing test case.
extdiff's uisetup will register new commands. If we do not include it in
confighash, changes to [extdiff] will not get new commands registered.
This patch adds extdiff to confighash and makes it possible for chg to pass
test-extdiff.t.
Using plural form is consistent with other progress units, and "1 out of 5
revisions" sounds more correct. Also, tests don't show this, but if you have
'speed' item in progress.format config, it shows e.g. '100 revisions/sec',
which also seems better.
Before this patch, import-checker reports error below for importing
subversion python binding libraries.
stdlib import "svn.*" follows local import: mercurial
Before this patch, import-checker reports "relative import of stdlib
module" error for importing Pool and SubversionException from svn.core
in subversion.py.
To fix this relative import of stdlib module, this patch adds prefix
'svn.core.' to Pool and SubversionException in source.
These 'svn.core.' relative accessing shouldn't cause performance
impact, because there are much more code paths accessing to
'svn.core.' relative properties.
BTW, in transport.py, this error is avoided by assignment below.
SubversionException = svn.core.SubversionException
But this can't be used in subversion.py case, because:
- such assignment in indented code block causes "don't use camelcase
in identifiers" error of check-code.py
- but it should be placed in indented block, because svn is None at
failure of importing subversion python binding libraries (=
examination of 'svn' is needed)
chgserver now validates and reloads configs automatically. Manually reloading
is no longer necessary. Besides, we are deprecating pid files since the server
will periodically check its ownership of the socket file and exit if it does
not own the socket file any longer, which works more reliable than a pid file.
This patch removes the SIGHUP reload logic from both chg server and client.
Actually since Python 2.3, there is some way to turn top level package into
"namespace package" so that multiple subpackage installed in different part of
the path can still be imported transparently. This feature was previously
thought (at least by myself) to be only provided by some setuptool black magic.
Turning hgext into such namespace package allows third extensions to install
themselves inside the "hgext" namespace package to avoid polluting the global
python module namespace. They will now be able to do so without making it a pain
to use a Mercurial "installed" in a different way/location than these
extensions.
The only constrains is that the extension ship a 'hgext/__init__.py' containing
the same call to 'pkgutil.extend_path' and nothing else. This seems realistic.
The main question that remains is: should we introduce a dedicated namespace for
third party extension (hgext3rd?) to make a clearer distinction between what is
officially supported and what is not? If so, this will be introduced in a follow
up patch.
Keeping the codebase in sync with upstream:
Watchman 4.4 introduced an advanced settling feature that allows publishing
tools to notify subscribing tools of the boundaries for important filesystem
operations.
https://facebook.github.io/watchman/docs/cmd/subscribe.html#advanced-settling
has more information about how this feature works.
This diff connects a signal that we're calling `hg.update` to the mercurial
update function so that mercurial can indirectly notify tools (such as IDEs or
build machinery) when it is changing the working copy. This will allow those
tools to pause their normal actions as the files are changing and defer them
until the end of the operation.
In addition to sending the enter/leave signals for the state, we are able to
publish useful metadata along the same channel. In this case we are passing
the following pieces of information:
1. destination revision hash
2. An estimate of the distance between the current state and the target state
3. A success indicator.
4. Whether it is a partial update
The distance is estimate may be useful to tools that wish to change their
strategy after the update has complete. For example, a large update may be
efficient to deal with by walking some internal state in the subscriber rather
than feeding every individual file notification through its normal (small)
delta mechanism.
We estimate the distance by comparing the repository revision number. In some
cases we cannot come up with a number so we report 0. This is ok; we're
offering this for informational purposes only and don't guarantee its accuracy.
The success indicator is only really meaningful when we generate the
state-leave notification; it indicates the overall success of the update.
Methods _put, _get, _stat were used in remotestore class as
abstract expecting that subclass would implement them. This
commit makes this fact explicit.
Extension to plug into a Watchman daemon, speeding up hg status calls by
relying on OS events to tell us what files have changed.
Originally developed at https://bitbucket.org/facebook/hgwatchman
In preparation for the filesystem monitor extension, include the pywatchman
library. The fbmonitor extension relies on this library to communicate with
the Watchman service. The library is BSD licensed and is taken from

This package has not been updated to mercurial code standards.
Consider the following use case. User has a set of commits he wants to rebase
onto some destination. Some of the commits in the set are already rebased
and their new versions are now among the ancestors of destination. Traditional
rebase behavior would make the rebase and effectively try to apply older
versions of these commits on top of newer versions, like this:
a` --> b --> a`
(where both 'a`' and 'a``' are rebased versions of 'a')
This is not desired since 'b' might have made changes to 'a`' which can now
result in merge conflicts. We can avoid these merge conflicts since we know
that 'a``' is an older version of 'a`', so we don't even need to put it on top
of 'b'. Rebaseskipobsolete allows us to do exactly that.
Another undesired effect of a pure rebase is that now 'a`' and 'a``' are both
successors to 'a' which is a divergence. We don't want that and not rebasing
'a' the second time allows to avoid it.
This was not enabled by default initially because we wanted to have some more
experience with it. After months of painless usages in multiple places, we are
confident enough to turn it on my default.
