Something deep in the bowels of distutils expects "version" passed to
setup() to be a str/unicode. So, convert the type.
This still works on Python 2 because the string is ascii and an
implicit coercion back to str/bytes should work without issue. If
it does cause problems, we can always make the unicode conversion
dependent on running Python 3.
This change makes `python3.5 setup.py install` work.
This was leading to some difficult to trace problems because the
values were set in one place, but then blew up much later in the
program. Exploding violently with an assertion seems reasonable here.
The _first field is used for tracking when to emit a separator between
items. It seems like it's clearly formatter state, not ui state, so
let's move it there.
By including the working directory revision at the start of rebase in
the repo._rebaseset, we make sure it's not hidden when we update back
to it at the end of the rebase.
This feels like abusing the set a bit given its name (_rebaseset), but
I couldn't think of another name that's clearly better.
This should catch the bug fixed by "worker: ignore meaningless exit status
indication returned by os.waitpid()."
Before, worker.py was untested since test repositories are relatively small.
Default-push has been deprecated in favour of default:pushurl. But "hg clone" still
inserts this in every hgrc file it creates. This patch updates the message by replacing
default-push with default:pushurl and also makes the necessary changes to test files.
Before this patch, worker implementation assumes that os.waitpid()
with os.WNOHANG returns '(0, 0)' for still running child process. This
is explicitly specified as below in Python API document.
os.WNOHANG
The option for waitpid() to return immediately if no child
process status is available immediately. The function returns
(0, 0) in this case.
On the other hand, POSIX specification doesn't define the "stat_loc"
value returned by waitpid() with WNOHANG for such child process.
http://pubs.opengroup.org/onlinepubs/9699919799/functions/waitpid.html
CPython implementation for os.waitpid() on POSIX doesn't take any care
of this gap, and this may cause unexpected "exit status indication"
even on POSIX conformance platform.
For example, os.waitpid() with os.WNOHANG returns non-zero "exit
status indication" on FreeBSD. This implies os.kill() with own pid or
sys.exit() with non-zero exit code, even if no child process fails.
To ignore meaningless exit status indication returned by os.waitpid(),
this patch skips subsequent steps forcibly, if os.waitpid() returns 0
as pid.
This patch also arranges examination of 'p' value for readability.
FYI, there are some issues below about this behavior reported for
CPython.
https://bugs.python.org/issue21791https://bugs.python.org/issue27808
Previously Abort raised during 'getbundle' call poorly reported (HTTP-500 for
http, some scary messages for ssh). Abort error have been properly reported for
"push" for a long time, there is not reason to be different for 'getbundle'. We
properly catch such error and report them back the best way available. For
bundle, we issue a valid bundle2 reply (as expected by the client) with an
'error:abort' part. With bundle1 we do as best as we can depending of http or
ssh.
bundle2 allow the server to report error explicitly. This was initially
implemented for push but there is not reason to not use it for pull too. This
changeset add logic similar to the one in 'unbundle' to the
client side of 'getbundle'. That logic make sure the error is properly reported
as "remote". This will allow the server side of getbundle to send clean "Abort"
message in the next changeset.
Changeset a0966f529e1b introduced a config option to have the server deny pull
using bundle1. The original protocol has not really been design to allow that
kind of error reporting so some hack was used. It turned the hack only works on
HTTP and that ssh server hangs forever when this is used. After further
digging, there is no way to report the error in a unified way. Using `ooberror`
freeze ssh and raising 'Abort' makes HTTP return a HTTP-500 without further
details. So with sadness we implement a version that dispatch according to the
protocol used.
Now the error is properly reported, but we still have ungraceful abort after
that. The protocol do not allow anything better to happen using bundle1.
We are about to add a test for ssh pull/cloning being denied because of bundle1
usage. For this, it is cleaner to not operate from the clone using http. So we
update the test beforehand for clarity. This is more churns that what I'm happy
to see on stable, but the rests of the series is worth it in my opinion.

We also add a test for pushing over ssh to make sure we won't regress in the
future. That test show that the hint is missing, this is another bug fixed in
the next changeset.
The remote hint message was ignored when reporting the remote error and
passed to the local generic abort error. I think I might initially have
tried to avoid reimplementing logic controlling the hint display depending of
the verbosity level. However, first, there does not seems to have such verbosity
related logic and second the resulting was wrong as the primary error and the
hint were split apart. We now properly print the hint as remote output.
This patch also makes some expected output lines in tests glob-ed for
persistence of them.
BTW, files below aren't yet changed in 2017, but this patch also
updates copyright of them, because:
- mercurial/help/hg.1.txt
almost all of "man hg" output comes from online help of hg
command, and is already changed in 2017
- mercurial/help/hgignore.5.txt
- mercurial/help/hgrc.5
"copyright 2005-201X Matt Mackall" in them mentions about
copyright of Mercurial itself
This patch replaces domain of mercurial-devel ML address by
mercurial-scm.org for "Report-Msgid-Bugs-To" property of each *.po
files.
This avoids releasing 4.1.1 with invalid "Report-Msgid-Bugs-To"
in *.mo file, if corresponded *.po file isn't msgmerge-ed with recent
hg.pot by translator.
These *.po files aren't covered by check-code.py pattern newly added
in subsequent patch, because it ignores them.
This patch also adds new check-code.py pattern to detect invalid usage
of "mercurial@selenic.com".
Change for test-convert-tla.t is tested, but similar change for almost
same test-convert-baz.t isn't yet tested actually, because I couldn't
find out the way to get "GNU Arch baz client".
AFAIK, buildbot skips test-convert-baz.t, too. Does anybody have
appropriate environment for testing?
In a flat manifest, a node with the same content but different parents is still
considered a new node. In the current tree manifests however, if the content is
the same, we ignore the parents entirely and just reuse the existing node.
In our external treemanifest extension, we want to allow having one treemanifest
for every flat manifests, as a way of easeing the migration to treemanifests. To
make this possible, let's change the root node treemanifest behavior to match
the behavior for flat manifests, so we can have a 1:1 relationship.
While this sounds like a BC breakage, it's not actually a state users can
normally get in because: A) you can't make empty commits, and B) even if you try
to make an empty commit (by making a commit then amending it's changes away),
the higher level commit logic in localrepo.commitctx() forces the commit to use
the original p1 manifest node if no files were changed. So this would only
affect extensions and automation that reached passed the normal
localrepo.commit() logic straight into the manifest logic.
