contrib: drop python 3.7 from the Windows dependency installer script
I'm tempted to drop 3.8 too, since we use 3.9 on Windows.
contrib: drop python 3.5 requirements file for Linux automation
The new minimum this cycle is py3.8.
windows: implement `util.cachestat` to fix numerous dirstate problems
I got here by bisecting the
issue1790 related failure on Windows to keep an
entry from being marked "unset" in `test-dirstate.t` back to
eedbf8256263.
There were a handful of other tests failing with an unexpected dirstate entry
state like this, as well as numerous "skip updating dirstate: identity mismatch"
messages added to various tests, as well as an issue with dirstate wrapping with
the largefiles extension[1], all of which appear to be fixed by this. In total,
~25 tests are fully fixed on Windows with this change on default.
This is basically a copy/paste of the posix implementation, but we drop the
`st_mode` comparison- I think the only reason we care about the mode on posix is
to detect +/-x mode changes, but the executable bits on Windows are synthesized
based on the name of the file[2]. None of the other parts of the codebase are
equipped to handle executable bits in the filesystem on Windows anyway, so it
doesn't make sense to worry about them here.
Note that `st_uid` and `st_gid` seem to always be 0 on Windows (and I can't find
them being initialized), so they can probably be dropped from the comparison.
But I doubt they matter any more on posix, since we don't track ownership. The
`st_ino`, `st_dev`, and `st_nlink` attributes all seem to have reasonable values
for comparing like on posix[3].
Also note that `st_ctime` is apparently deprecated in 3.12+ (for reasons I
haven't explored)[4].

extdiff: don't run gui programs when in a cli-only environment
In order to provide a useful error message to override the behavior, we also
need to slightly change the way that tool.gui is found in the config. Before,
it had to be where tool.diffargs is located, which might not exist. Now,
tool.isgui can exist on its own.
A test is added for the new error message. We also need to force
procutil.isgui() to return true, so we set $DISPLAY to a non-empty value
before running any test expecting to have a gui.
doc: generate separate commands/topics/extension pages
This change modifies gendoc.py and Makefile so that individual pages for
commands, help topics, and extensions can be generated. A new index page is
also generated with links to all these pages. This makes it easier to look up
and search the help text of a given command or topic, instead of having to
deal with the giant hg.1 "all-in-one" page.
Since the list of individual pages varies based on the source code, we generate
a dynamic Makefile that contains this list of files as individual targets.
This gives us fine-grained control over output files. However, it greatly
increases the time spent generating all help pages. It's recommended to run
make with -j to make use of multi-core archs.
Individual man pages are produced in doc/man, and HTML ones are in doc/html
doc: refactor gendoc for better reusability
This change separates the gathering of commands/topics/etc from the logic of
printing their documentation out.
stream: prefer keeping an open file handle to volatile file instead of copy
We will still do copy if too many file handle are open. Currently, have less
than 10 volatile files in typical usage, so we should be fine.
See inline documentation for details.
stream: remove __getitem__ from the VolatileManager
It is no longer used and that API will get in the way of the new order.
stream: open volatile file through the manager
To do more subtle things, we need more control.
