Previously, "hg serve" will listen on "", which is not clear which interface
it will actually listen on - it could listen on all interfaces (ex. 0.0.0.0
on IPv4).
The run-tests.py script only checks "localhost" for available ports. So
let's make it the same for "hg serve" by explicitly setting "web.address" to
"localhost".
This resolves some IPv6 EADDRINUSE errors.
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.
Now that servers expose a capability indicating they support
application/mercurial-0.2 and compression, clients can key off
this to say they support responses that are compressed with
various compression formats.
After this commit, the HTTP wire protocol client now sends an
"X-HgProto-<N>" request header indicating its support for
"application/mercurial-0.2" media type and various compression
formats.
This commit also implements support for handling
"application/mercurial-0.2" responses. It simply reads the header
compression engine identifier then routes the remainder of the
response to the appropriate decompressor.
There were some test changes, but only to logging. That points to
an obvious gap in our test coverage. This will be addressed in a
subsequent commit once server support is in place (it is hard to
test without server support).
On Windows platform, invoking printenv.py directly via hook is
problematic, because:
- unless binding between *.py suffix and python runtime, application
selector dialog is displayed, and running test is blocked at each
printenv.py invocations
- it isn't safe to assume binding between *.py suffix and python
runtime, because application binding is easily broken
For example, installing IDE (VisualStudio with Python Tools, or
so) often requires binding between source files and IDE itself.
This patch invokes printenv.py via sh -c for test portability. This is
a kind of follow up for 9e4331825bea, which eliminated explicit
"python" for printenv.py. There are already other 'sh -c "printenv.py"'
in *.t files, and this fix should be reasonable.
This changes were confirmed in cases below:
- without any application binding for *.py suffix
- with binding between *.py suffix and VisualStudio
This patch also replaces "echo + redirection" style with "heredoc"
style, because:
- hook command line is parsed by cmd.exe as shell at first, and
- single quotation can't quote arguments on cmd.exe, therefore,
- "printenv.py foobar" should be quoted by double quotation, but
- nested quoting (or tricky escaping) isn't readable
Some systems (like FreeBSD jails) use something other than 127.0.0.1
for localhost, and it's not safe to assume it'll always be the same
width. Using sed with a replacement like this sidesteps the problem.
chg currently does not support hg serve -d. It has a quick path testing if the
command is hg serve -d and fallbacks to hg if so. But the test only works if
"serve" is the first argument since the test wants to avoid false positives
(for example, "-r serve" is different).
This patch reorders "hg server" commands in tests, making them chg friendly.
Sometimes a txnclose or changegroup hook wants to iterate through all
the changesets in transaction: in that situation usually the revset
`$HG_NODE:` is used to select the revisions. Unfortunately this revset
sometimes may contain too many changesets because we don't have the
write lock while the hook runs newer changes may be added to
repository in the meantime.
That's why there is a need for extra variable carrying the information about
the last change in the transaction.
We want to keep both code paths tested. The test is a bit too extensive to
simply introduce dual testing in it so we make a copy for each protocol
version.
