When on a filelog head, we are certain that there will be no descendant so the
target of the "descending" link will lead to an empty log result. Do not
display the link in this case.
We set parent._descendantrev = child.rev() when walking parents in
blockancestors() so that, when linkrev adjustment is perform for these, it
starts from a close descendant instead of possibly topmost introrev. (See
`self._adjustlinkrev(self._descendantrev)` in filectx._changeid().)
This is similar to changeset 8758896efb1c, which added a "f._changeid"
instruction in annotate() for the same purpose.
However, here, we set _descendantrev explicitly instead of relying on the
'_changeid' cached property being accessed (with effect to set _changeid
attribute) so that, in _parentfilectx() (called from parents()), we go through
`if '_changeid' in vars(self) [...]` branch in which instruction
`fctx._descendantrev = self.rev()` finally appears and does what we want.
With this, we can roughly get a 3x speedup (including in example of issue5538
from mozilla-central repository) on usage of followlines revset (and
equivalent hgweb request).
Update the hunk selector help message to use the operation name instead
of using "record" for all operations. Extract the help message in the same way
as other single and multiple message line.
Update tests to make sure that both "revert" and "discard" variants are tested.
This makes the test pass in Python 2.6. It's all one of two problems:
1)
abort: error: '' (2.7)
vs
abort: error: (2.6)
2) 65537 (2.7) vs -1 (2.6)
With some...unfortunate escaping required due to how regular
expressions work. Sigh.
Now that environment variables override system-wide hgrc settings, we
can default Mercurial to sensible-editor and sensible-pager by default
for debian users.
test-http-bad-server has a flaky output case that reproduces fairly
often (20% or more of runs on my Mac) on BSD-family OSes. So that
tests can be green for the 4.2 release, let's more or less give up on
this output, and plan to pursue it in the future.
Previously, calling blockancestors() with a fctx not touching file would
sometimes yield this filectx first, instead of the first "block ancestor",
because when compared to its parent it may have changes in specified line
range despite not touching the file at all.
Fixing this by starting the algorithm from the "base" filectx obtained using
fctx.introrev() (as done in annotate()).
In tests, add a changeset not touching file we want to follow lines of to
cover this case. Do this in test-annotate.t for followlines revset tests and
in test-hgweb-filelog.t for /log/<rev>/<file>?linerange=<from>:<to> tests.
Resolves test failures on FreeBSD, but I'm not happy about the fix.
A previous version of this also wrapped readline by putting the hack
in the _call method on doublepipe. That was confusing for readers and
wasn't necessary - just doing this on read() is sufficient to fix the
bugs I'm observing. We can always come back and do readline later if
needed.
`hg show work` is much more usable if output is colored. This patch
implements coloring via label() in a very hacky way.
In a default Mercurial install, you'll see yellow node labels for all
phases. Branches and bookmarks use the same formatting as the commit
message. So this change doesn't help much in a default install. But if
you have a custom colors defined for these things, output is much more
readable.
The implementation obviously needs some work. But for a minor change
on a feature that isn't convered by BC, this seems like a clear win
for the feature in 4.2.
Durham and I both like this better than "underway." We can add aliases
and bikeshed on the name during the 4.3 cycle, as this whole extension is
highly experimental.
Previously, we'd rely on the implicit check that `localrepo.commit` did.
The problem is that that check only happened when the working copy was
dirty. With a "clean" working copy but unresolved conflicts we'd get
into a broken state.
To fix that, do what rebase does and check for unresolved conflicts at
the start of histedit --continue.
See the inline comment how this could mitigate the issue.
I couldn't reproduce the exact problem on my Linux machine, but there are
at least two people who got EINTR in progress.py, and it seems file_write()
of Python 2 is fundamentally broken [1]. Let's make something in on 4.2.

Some shared-ssh installations assume that 'hg serve --stdio' is a safe
command to run for minimally trusted users. Unfortunately, the messy
implementation of argument parsing here meant that trying to access a
repo named '--debugger' would give the user a pdb prompt, thereby
sidestepping any hoped-for sandboxing. Serving repositories over HTTP(S)
is unaffected.
We're not currently hardening any subcommands other than 'serve'. If
your service exposes other commands to users with arbitrary repository
names, it is imperative that you defend against repository names of
'--debugger' and anything starting with '--config'.
The read-only mode of hg-ssh stopped working because it provided its hook
configuration to "hg serve --stdio" via --config parameter. This is banned for
security reasons now. This patch switches it to directly call ui.setconfig().
If your custom hosting infrastructure relies on passing --config to
"hg serve --stdio", you'll need to find a different way to get that configuration
into Mercurial, either by using ui.setconfig() as hg-ssh does in this patch,
or by placing an hgrc file someplace where Mercurial will read it.
mitrandir@fb.com provided some extra fixes for the dispatch code and
for hg-ssh in places that I overlooked.
If we use the normal vfs, store encoding will be applied when we
.join() the path to be copied. This results in attempting to copy
a file that (likely) doesn't exist. Using the rawvfs operates on
the raw file path, which is returned by vfs.readdir().
Users at Mozilla are encountering this, as I've instructed them to
run `hg debugupgraderepo` to upgrade to generaldelta. While Mercurial
shouldn't deposit any files under .hg/store that require encoding, it
is possible for e.g. .DS_Store files to be created by the operating
system.
`hg debugupgraderepo` is currently buggy with regards to path
handling when copying files in .hg/store/. Specifically, it applies
the store filename encoding to paths instead of operating on raw
files.
This commit adds a test demonstrating the buggy behavior.
Previously, the "oldheads" variable was a list. On a repository at
Mozilla with 46,492 heads, profiling revealed that list membership
testing was dominating execution time of applying small changegroups.
This patch converts the list of old heads to a set. This makes
membership testing significantly faster. On the aforementioned
repository with 46,492 heads:
$ hg unbundle <file with 1 changeset>
before: 18.535s wall
after: 1.303s
Consumers of this variable only check for truthiness (`if oldheads`),
length (`len(oldheads)`), and (most importantly) item membership
(`h not in oldheads` - which occurs twice). So, the change to a set
should be safe and suitable for stable.
The practical effect of this change is that changegroup application
and related operations (like `hg push`) no longer exhibit an O(n^2)
CPU explosion as the number of heads grows.
Previously, `hg bundle zstd` on a non-generaldelta repo would
attempt to use a v1 bundle. This would fail because zstd is not
supported on v1 bundles.
This patch changes the behavior to automatically use a v2 bundle
when the user explicitly requests a bundlespec that is a compression
engine not supported on v1. If the bundlespec is <engine>-v1, it is
still explicitly rejected because that request cannot be fulfilled.
Version 1 bundles only support a fixed set of compression engines.
Before this change, we would accept any compression engine for v1
bundles, even those that may not work on v1. This could lead to
an error.
We define a fixed set of compression engines known to work with v1
bundles and we add checking to ensure a newer engine (like zstd)
won't work with v1 bundles.
I also took the liberty of adding test coverage for unknown compression
names because I noticed we didn't have coverage of it before.
For consistency with the other template options. Quotes are necessary if
you want to preserve leading/trailing whitespace, which would be stripped
by config parser.
I got the following error by running "hg log" and quitting the pager
immediately. Any output here may trigger another SIGPIPE, so only thing
we can do is to swallow the exception and exit with an error status.

Perhaps this wasn't visible before ee4f321cd621 because the original stderr
handle was restored very late.
Before, it crashed because mapping['templ'] was missing. As it didn't support
the legacy list template from the beginning, we can simply use hybridlist().
See the previous commit for why.
splitlines() does not pass a mapping dict, which would probably mean the
legacy template didn't work from the beginning.
Now that all known format variants exists outside of the function, we can gather
them in a lists. This build a single entry point other code can use (current
target: extensions).
The repository upgrade code is updated to simply use entries from this list.
As a side effect this will also allow extensions to register their own format
variants, to do this "properly" we should introduce a "registrar" for this
category of object. However I prefer to keep this series simple, and that will
be adventure for future time.
