match: adding support for matching files inside a directory This adds a new "rootfilesin" matcher type which matches files inside a directory, but not any subdirectories (so it matches non-recursively). This has the "root" prefix per foozy's plan for other matchers (rootglob, rootpath, cwdre, etc.).

runtests: add an IPv6 command line flag Now we have all IPv6 related issues fixed, add a command line flag so people could actually run tests with IPv6.

runtests: always set web.ipv6 Previously, we only set web.ipv6 if IPv6 is used, but not on the IPv4 case. Since we already have set web.address, it makes sense to move "web.ipv6" out from "extra config options".

runtests: set web.address to localhost 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.

tests: use LOCALIP This patch replaces hardcoded 127.0.0.1 with $LOCALIP in all tests. Till now, the IPv6 series should make tests pass on common IPv6 systems where the local device has the address "::1" and the hostname "localhost" resolves to "::1".

dummyssh: use LOCALIP This patch replaces hard-coded 127.0.0.1 with $LOCALIP in dummyssh.

runtests: export LOCALIP Previously, tests hard-code local IP address as "127.0.0.1". That won't work for IPv6. This patch exports the $LOCALIP environment variable, which is set to "::1" if we decide to use IPv6.

tinyproxy: use IPv6 if HGIPV6 is set to 1 This patch makes tinyproxy.py work in IPv6 mode if HGIPV6 is set to 1. This will make test-http-proxy.t pass on IPv6 machines.

dumbhttp: use IPv6 if HGIPV6 is set to 1 This will fix flaky tests using dumbhttp. The patch was tested on gcc112.fsffrance.org using the following command: ./run-tests.py -j 40 --runs-per-test 120 test-bundle2-remote-changegroup.t

runtests: export HGIPV6 to hint test scripts whether to use IPv6 Previously, run-tests.py only exports HGPORT, and scripts in tests do not know if IPv6 should be used. And that breaks scripts like dumbhttp.py which always uses IPv4. This patch makes run-tests.py export HGIPV6, which can help test scripts like dumbhttp.py and tinyproxy.py to decide whether to use IPv6 or not.

runtests: prefer IPv4 to IPv6 To make IPv6 work, there are multiple areas that need to fix. Before they all get fixed, use IPv4 by default. This should fix tests caused on IPv6 systems.

doc: correct example concerning "hg purge" alias in man page "hgrc.5" The "hg purge" alias as currently described in "hgrc.5" issues a possibly confusing error message like rm: missing operand Try 'rm --help' for more information. if no files are to be purged at all. This patch slightly modifies the example by adding a "-f" option to the "rm" command.

tests: prove that ignore works

annotate: migrate to modern pager API

ui: add a debug print right before we start the pager This makes it easier to figure out why a command is getting paginated.

ui: respect historic pager.attend-$COMMAND=no I'm on the fence about this behavior, but the user's intent was pretty specific and it's not expensive to support this case.
