util: implement pop() on lrucachedict
This moves __delitem__() to pop() as the requirement is pretty much the same,
and reimplement __delitem__() by using pop().
util: add method to peek item in lrucachedict
I want a function that doesn't unnecessarily update the internal state of
the cache dict after fork().
commandserver: loop over selector events
An IPC socket will be waited by the same selector.
commandserver: extract handler of new socket connection
This prepares for adding an IPC socket.
commandserver: pass around option to hook repo instance creation
This is necessary to wrap a repo instance so the master process will be
notified on repo.close().
py3: stop subscripting socket.error
In 3.3 and later, this is now an alias for OSError. I hacked up the server code
enough that I was able to trigger the exception handler in server.py from
test-http-bundle1.t. Other instances of this either subscript through the
`args` member, or reference the errno or strerror attributes.
Note that on Windows, the errno value seems to reflect the Winsock error, so the
various tests for EPIPE seem like they would always fail. But that seems to be
the case in py2 as well.
test: update test-logtoprocess.t to not requires less
The test previously assumed that a working pager was present in the test
environment. Update it to use the fakepager instead.

py3: quote several instances of $PYTHON for Windows
Python3 lives in Program Files by default. The last remaining unquoted instance
is in test-hghave.t. I can't figure out how to quote that, as it either
complains:
'c:\\Program' is not recognized as an internal or external command,
operable program or batch file.
or
$TESTTMP.sh: line 22: "C:/Program Files/Python37/python.exe": $ENOENT$
py3: convert filename to bytes in test-hardlinks.t
Windows was complaining about passing str to CreateFileA() in win32.py.
narrow: keep bookmarks temporarily stripped for as long as commits are
The narrow extension also has support for shallowness and for
inserting older commits on pull. It works by temporarily stripping
newer commits, adding the older commits, then re-applying the stripped
bundle. The regular Mercurial server uses that when you widen,
although it shouldn't be necessary there. Our Google-internal server
does it when the user requests an older commit.
Our Google-internal tests fail since
7caf632e30c3 (filecache:
unimplement __set__() and __delete__() (API), 2018-10-20). I haven't
quite understood the problem, but it's related to the way we
temporarily hide bookmarks while the commits they point to are
stripped. When a transaction is started, Mercurial tries to read
various things from the repo for the transaction summary. That leads
to computation of hidden commits, which leads to an attempt to find
commits pinned by bookmarks. This is the reason we temporarily hide
the bookmarks. I think the aforementioned commit makes the restored
bookmarks visible earlier than before (which seems like an
improvement), so we can no longer incorrectly rely on the
repo._bookmarks field being cached too long (IIUC).
This patch makes it so we restore the temporarily hidden bookmarks
only after the temporary bundle has been re-applied. It also adapts
the code to update the repo.__bookmarks field using the pattern
described in the aforementioned commit instead of writing directly to
the fiels.
I have spent many hours trying to understand what was going on here,
but I still don't know if this can also happen without our custom
server. So this patch unfortunately does not add any tests; I have
only been able to test the fix using our Google-internal tests.

narrow: drop obsolete support for old Mercurial
Not needed since narrow is shipped with core.
