OK.  But to be fair, I had zero experience with Android development
myself before working on this; I have taken care to keep the Java code
as minimal as possible and comprehensible to C developers.

Sure.  Please feel free to describe what you find confusing, and I will
try to document it in the README in the java directory.

I tried to find the scroll bars in a real (as in, not Emacs) Android
application, and could not find any at all.  The scroll bar in the
toolkit does not respond to input at all, and disappears after you
finish scrolling.  Besides, the Emacs scroll bar implementation I worked
on had major problems adapting to touch screen input.

Yes, please do so.  Thanks.

It isn't just about the Java directory.  It's every point where the
Android port deviates from its desktop/laptop behavior.  Starting with
dumping, then the fact that we compile to shared libraries instead of
executables, etc. etc.

?? The Web browser comes to mind and the email client.  The scroll bar
in both is quite functional.

Ah.  Here, in Mozilla Firefox, I can't find any scroll bars at all.
K9 mail does have them, but of the disappearing kind.  What vendor made
your Android device?

Preferably on the android_*.c files, each file with its part of the
story.  Alternatively, you could have a separate android-internals.txt
file in admin/notes/, I suppose.

Samsung.  I tried their own browser (which AFAIU is a derivative of
Chromium), not Firefox.

It sounds like on Android, scroll bars are not unified, and each app
provides what it wants.  But it is definitely possible to have a
functional scroll bar.

OK, thanks.  I think the latter would be easier.

Thanks.  I'll take a look at what the Samsung browser does.

I guess so.  The non-functional scroll bar I was referring to is the
scroll bar provided by the Android toolkit as part of the ScrollView
widget.

I ended up putting a significant writeup in java/README, as that's where
the Nextstep port has its documentation, which is supposed to teach us
Emacs developers Objective-C.

Would you please read it and say what you think?
I will extend it in the next few days to describe more of the GUI code
as well.

Thanks.

Google is working on allowing the proprietary drivers to run alongside
any version of Linux, not on removing them entirely.

Google themselves develop Play Services, arguably the most problematic
piece of proprietary software in Android.

LineageOS and CyanogenMod are not free software, because both contain
proprietary device driver files, and in the case of CyanogenMod,
proprietary user level libraries as well.

AOSP, on the other hand, is really free software.  But that doesn't help
when you can only run it in an emulator.

If you had read the Android appendix of the Emacs manual, you would have
seen that it explains this situation:

H.1 Android history
===================

Android is an operating system for mobile devices developed by the Open
Handset Alliance, a group of companies interested in developing handsets
that can run a common set of software.  It is supposedly free software.

   Like the X Consortium of times past, the Open Handset Alliance
believes that “openness” (namely, the regular release of the Android
source code) is simply a tool to increase the popularity of the Android
platform.  Computer companies normally produce proprietary software.
The companies in the Open Handset Alliance are no different – most
versions of Android installed on devices are proprietary, by virtue of
containing proprietary components, that often cannot even be replaced by
the user.

   Android is not designed to respect users’ freedom.  Almost all
versions of Android (including some which are supposedly free software)
include support for Digital Restrictions Management, technology that is
designed to limit users’ ability to copy media to and from their own
devices.  Most Android devices also come with proprietary Google
applications which are required to run the system, and many other
Android applications.

   Thus, it must be necessary to consider Android proprietary software
from a practical standpoint.  That is an injustice.  If you use Android,
we urge you to switch to a free operating system, if only for your
freedom’s sake.

   We support GNU Emacs on proprietary operating systems because we hope
this taste of freedom will inspire users to escape from them.

We are not going to use features only in proprietary versions of Android
because we hope that the resulting Emacs binaries will also work on free
operating systems such as AOSP and Replicant.

But Android itself is proprietary from a practical standpoint, so we
will continue to treat it as a proprietary platform wrt its support in
Emacs, if only because free Android is available for a minuscule amount
of users.

I didn't because a link to the branch was never posted in the thread ☺

Either way, now I see the point you are trying to make as you're using an
expression "from a practical standpoint it is closed". So, like, in theory it is
open, but in practice no device runs the original Android.

In my head I still can't connect the relevance of that "practice" to Emacs
Android  port though, because you can treat the port as a program that is
supposed to run on the original open platform, and then, almost "accidentally"
(not really, but I hope you see my point), as an app that can run on any other
Android device…

But I won't be going into that further because my main motivation for
participation was to make sure your work on making the port isn't wasted, which,
judging by your reply, seem to have been resolved before I joined.

So, anyway, thanks for your work!

I believe the Android port of Emacs is now more or less feature
complete.

It can be found on the feature/android branch of the Emacs repository,
and should support all (mipsel, arm, armv7l, mips64, aarch64 and x86)
Android devices capable of running Android 2.2 or later.  You can obtain
a check out of that code like so:

  $ git clone git://git.sv.gnu.org/emacs.git -b feature/android

Please give it as much testing as you can on real hardware from many
different Android vendors.  Follow the instructions in INSTALL.android
to build and install Emacs for your specific device.  In addition,
please submit patches and report editing modes that do not work well
with the input methods of various on screen keyboards, along with other
bugs, using ``M-x report-emacs-bug RET.''

The answers to various common questions (such as ``how to access
external storage'', or ``where does Emacs put its init.el'') are in the
Android appendix of the Emacs manual in the branch.

Prebuilt binaries will be made available shortly, but please do not
expect them to contain all dependencies with which Emacs can be built.
At present, I don't recommend using binaries from f-droid.org, since
they are out of date, but I will ask the f-droid packagers to rectify
that problem.

I will post this news to comp.emacs; please post this to other forums
frequented by Emacs users as well.

I look forward to having these binaries available.  I had already
installed an earlier version from f-droid but would like to test this
latest version.  Note that I am testing on a system probably more suited
to Emacs than the typical phone as mine has a physical keyboard: Planet
Computers Gemini.  Screenshot of Emacs on that phone:

Thanks for the effort.  I was quite excited for this.

For now, I was trying to make an out-of-tree build without gnutls.  This
configuration appears to be broken (though, not due to gnutls):

  make[2]: Entering directory '/home/arsen/gnu/emacs-android/build/java'
  make[2]: *** No rule to make target '../java/Makefile.in', needed by 'Makefile'.  Stop.
  make[2]: Leaving directory '/home/arsen/gnu/emacs-android/build/java'

I'll report a fix when I come up with one.

Have a lovely day.

Out of tree builds are currently not supported because of some specifics
related to the ``aapt'' tool and ``ndk-build'' system used by Android.

I'd not attempt wasting time trying to fix that.

Sure.  In-tree worked as expected, and I see Emacs on the phone.  I'll
try porting more tangible parts of my scripts in a few days.

I see (https://f-droid.org/it/packages/org.gnu.emacs) the package was added on 2023-02-09.. Why is it not "good"? has it been built with your method or does it belong to another project? Which?

There it says the package is for Android >= 5.1 while you says your work is for Android > 2...

TIA,
 Angelo.

The C compiler they used is too new for the resulting binary to work on
older versions of Android.

Emacs is not like other programs, where one binary can run on any number
of systems.  You should build Emacs for an API level reasonably close to
what you will install it on, and with the right C compiler for that.

Otherwise, you will get gnulib substitutes for several system functions,
which may not be what you want.

I gave a try to the F-Droid package installing it on a device with android 11. I use this device with mouse and keyboard (the delete key does not work in Emacs). 

I enabled Emacs to have access to all the files.

When I start Emacs there is a notification [See (emacs) Android Environment for more details about this notification]: what it means is a mystery.

The font on this system is too small and I would increase it as I do, for example, with my build on GNU/Linux. But How is this font called? I cannot establish this from Options - Set Default Font

It seems that HOME (~/) is "/data/data/org.gnu/files" which cannot be accessed from, for example, Termux (this app has access to /data/data/com.termux/). So it is hard (but not impossible) to comunicate with the "external world" (for example to move an init.el, taken from another system,  to ~/.emacs.d/: this would facilitate the setup of this android Emacs.

In any case, I created a ~/.emacs.d/init.el and added something like

(global-tab-line-mode 1)

(setq tab-line-tabs-function 'tab-line-tabs-buffer-groups)
(setq tab-line-close-tab-function 'kill-buffer)

(setq auto-save-list-file-prefix nil)

(column-number-mode 1)
(delete-selection-mode 1)
(electric-pair-mode 1)
(savehist-mode 1)
(tool-bar-mode -1)

Needless to say, Emacs crashes all the time and I have to try many times to write that. And if I add

(desktop-save-mode 1)

it crashes during startup, mainly if one want to load desktop file blocked by the lock file left there by previous crash..

BTW, the About Emacs says it is a

  build 1, aarch64-unknown-linux-android220 of 2023-02-18

Why 2023-02-18 if the package was made 10 days ago?

As it says, you should read the node ``Android Environment'' in the
Emacs manual.  This notification is displayed to prevent Emacs from
being killed after entering the background.

Android security policy prevents applications from accessing each others
home directories, so yes, it is not easy to access.

Copying an init.el from another system is best done through the system
file manager or by copying the files into Emacs's home directory via the
external storage.

File managers on most proprietary versions of Android refuse to display
Emacs's home directory, because they are more keen to display
advertisements than to actually manage files.

First, try with an up to date build.  Next, please show the output of
the following command with your device connected to a computer (once
again, this is described in the Android appendix of the Emacs manual, so
please read it.)

  adb logcat | grep android_run_debug_thread

I will look into that.

Android does not correctly report the date of an executable.
It is always the present.

Here the file manager does not show Emacs directory.. or at least I cannot find it.. It is unclear the last sentence: from Emacs I can visit a file, say in /sdcard/Download/, but HOW copy it in Emacs, say in ~/?

Finally something that I can answer. :-)

To use adb on Linux you need to do the following:

1. Enable debug mode on the android device. The way you do this
depends on the device, but it typically involves tapping five to seven
times on the system about kernel version. Look for it on the web.
2. After enabling debug mode looking for "USB debugging" on the device
and turn it on.
3. Connect the android device to the computer by cable.
4. Run `adb shell` on your computer. This will fail to connect because
of permissions.
5. On the android device you will get a popup asking whether you want
to allow usb debugging from your computer. Confirm this.
6. Back in the computer terminal do a `killall adb` to remove the
previous adb process (it installs itself as a server). And redo it.
7. You will now have a shell into your device. :-)

You can use adb to copy files `adb push` and `adb pull` to the device.

You can also use `adb logcat` and filter the output by regexps.

Hope this helps!

Looking forward to using emacs on my android tablet!

Dov

In Emacs, there's also Tramp's "adb" method. If you have only one
Android device, you can access it via "C-x C-f /adb::" from your local
Emacs, running on Linux.

The only missing feature is support of "adb logcat". Shall we add
something like this?

On my device, which uses a near-vanilla build of AOSP, Emacs is visible
in the hamburger menu on the left in the Files app, below the SD card
option, and above Termux.  Do you see something similar on your device?

FWIW, I could reproduce this on 1f81186d67b2a86e6a555a7ad3323fcd13f5e257
but not c8f49c9276d34741bfbe7752dd38391c0b8d782b, so, it may be fixed.

You could, technically, though it's likely easier to do it on your PC.
Enable USB debugging, install the adb package.  Your normal
charging/data transfer cable ought to work.

If you click the three line menu on the top left, the file manager
should display a panel containing a list of mounted ``volumes''.

A volume labelled ``Emacs home directory'' should be visible.

That will not work, unless you connect your phone to itself via its adb
port.

If you run `logcat' from a directory in /adb::, it will work just as
well as if you ran `adb logcat'.

Everyone, do we need this information in the Emacs manual?

Hi,

While building initially, I got some make errors that looked like they
were from a race, for example:

    GEN         execinfo.h
  mv: cannot stat 'execinfo.h-t': No such file or directory

Further confirming my suspicion that these are coming from a race is
Emacs compiling fine if make is reinvoked, and that a non-parallel make
build works fine.

I figured this was a fluke initially, but, I reproduced the issue today.
You can fetch the build log from here:
https://www.aarsen.me/~arsen/emacs-races.script

There also appears to be a dependency missing between generating the APK
and running the pdumper, or such, since I could re-run make after make
concluded in the nonparallel case.

This seems pretty reproducible on my machine, I suspect due to the large
number of -t files utilized in Gnulib.

-- 8< --

While I'm around, I was also thinking about how to enable using the
modifier keys on virtual keyboards without modifiers.  I was considering
mapping a key, say, KEYCODE_VOLUME_DOWN to ESC if pressed and Ctrl if
held in combination with another key, hence, the sequence Press VolDown,
Release VolDown, Press VolDown, Type x, Release VolDown would be parsed
as ESC C-x, or C-M-x.  Do you know if this is possible?  All methods
that I know rely on external tools (XKB configs, AHK, ...) that are not
available on android.

Thanks in advance.

Yes, but better to direct users to the official documentation (https://developer.android.com/studio/command-line/adb) rather than try to describe it ourselves, I think.

Another moderately convenient option is KDE Connect, which consists of a pair of applications to run on an Android device and a normal computer to provide a range of integrations between them.  One of the integrations offered is file sharing.

It is developed by the KDE project, but using the KDE desktop is not required.

Great. Tramp's adb method supports remote processes. so with a proper
default-directory, one can call from Emacs

--8<---------------cut here---------------start------------->8---
(async-shell-command "logcat | grep android_run_debug_thread")
--8<---------------cut here---------------end--------------->8---

Best regards, Michael.

I guess the best thing to do is to try installing a version of Android
on your device that will let you use Android's own free file manager.
Alternatively, copy the file(s) to `/sdcard' and then copy them to
Emacs's home directory from inside Emacs.

> Ever since there was the upgrade to android 11 problems began...

It would be more appropriate to call such changes to your system
downgrades.

This should not be a problem, since the dumping happens on-device on
Android.

I will look into this, thanks.

I'm not sure how to do this, since those keys are not ``meta modifiers''
on the system.

I'd recommend an on screen keyboard which has those modifier keys
instead.

Please see if the parallel build has been fixed.  Thanks.

One build passed fine, so my guess is yes.  I'll let it spin for a bit
with GNU Make's --shuffle, too, and report if anything comes up.

Thanks!

Indeed, that'd require some state tracking, for instance, on press reset
a special-as-ctrl flag and set a special-held flag, if anything else is
typed interpret it as C-<N> if special-held is set and set
special-as-ctrl, and on key release, reset special-held and emit an ESC
if special-as-ctrl is reset.

I'm not aware of a better solution because, as you said, these keys
aren't modifiers, and register as normal keypresses.

My thinking here is that providing an alternative for folk who don't use
virtual keyboards with modifier keys already (which is, most likely,
almost everyone) could ease their transition and help them with muscle
memory.

Have a splendid day.

Hi,

I encountered another one:

  javac -classpath "/home/arsen/Android/Sdk/platforms/android-Tiramisu/android.jar:." -target 1.7 -source 1.7 -Xlint:d
  eprecation org/gnu/emacs/EmacsContextMenu.java

I tried replicating with that shuffle= value, but it seems that I did
not get lucky twice.  However, I believe I have the reason why:

  ~/gnu/emacs-android2 130 $ grep -r --include='*.java' Holder
  java/org/gnu/emacs/EmacsService.java:class Holder<T>
  java/org/gnu/emacs/EmacsService.java:    final Holder<EmacsView> view;
  java/org/gnu/emacs/EmacsService.java:    view = new Holder<EmacsView> ();
  java/org/gnu/emacs/EmacsService.java:    final Holder<ClipboardManager> manager;
  java/org/gnu/emacs/EmacsService.java:    manager = new Holder<ClipboardManager> ();

  java/org/gnu/emacs/EmacsContextMenu.java:    final Holder<Boolean> rc;
  java/org/gnu/emacs/EmacsContextMenu.java:    rc = new Holder<Boolean> ();

There is no dependency between these Holder<T> users and the .java that
provides it:

The simplest way to fix it is probably to break out Holder<T> into
Holder.java, as that won't require manually bookkeeping the
dependencies.  I attached a patch, which builds on x86_64-pc-linux-gnu.

Thanks.  The make depends thing is supposed to be done by javac
internally, and it should scan through source files in
org/gnu/emacs to find missing definitions.

I will try to fix the group rule definition.

Dired, or running `cp' in a shell buffer.

I believe it only scans through source files listed on the command line
and through the classpath.

Yes, I believe this is the proper fix.  I was getting a bunch of other
errors in similar vein after fixing the one above, except even stranger,
so I suspect javac is quite bad at parallelizing.  The group build you
pushed earlier should alleviate that at a slight hit to compile speed
(which I doubt it's major enough to warrant build-time instability).

Thanks.

org/gnu/emacs is in the classpath.

Thanks for finding this bug in javac.

Yes, and the sourcepath too, but I don't think the sources in those
paths are re-parsed to grab class definitions on each build, which is
where the problem stems for, but are instead parsed on an as needed
basis, with the classes available being presumed to map 1-to-1 to the
list of .java files in the sourcepath.

Sure, if you end up reporting it, please keep me posted.  I'm curious
about what the intended behavior here is.

Thanks.

On GNU/Linux (Mint) I change the size of default (Monospace) font with

(set-frame-font "Monospace-11" nil t)

(setq default-frame-alist
      '(
        ;;(width . 120) ; character
        ;;(height . 54) ; lines
        ;;(left . (- 0)); pixel
        ;;(top  . (+ 0)); pixel
        ;;(left . 835); pixel
        ;;(top  .   0); pixel
        (font . "Monospace-11") ; font
        ))

in the init.el file. How can I do the same with this android Emacs? I cannot establish the name of the font it is using...

As the manual says, ``Droid Sans Mono''.

A prebuilt binary for 64-bit ARM devices running Android 5.1 or later
can be found at:

  https://sourceforge.net/projects/android-ports-for-gnu-emacs/files

Note that because F-Droid chose to sign their release with their own
signing key, you will have to uninstall the F-Droid version before
installing this one.

Thanks.

I tried the last binaries (emacs-30.0.50-21-arm64-v8a.apk) and copied almost the full .emacs.d I have on GNU/Linux (with the elpa/melpa packages etc.). The result almost works but there are the following issues:

- some "random" crash (3-4 in few hours)

- when in the init file I have:

   (global-auto-revert-mode 1)

  the device vibrates and in the minibuffer shows up: "Error while reading file system events: try again". So I commented that out

- when i click on the Options menu the minibuffer shows: "Wrong type argument: stringp, nil" and the menu does not open. The other menu (File, Edit etc open regularly)

- last but not least, the DELETE key on the keyboard does not work.

It seem you have don big step forward!

If I could chime in here. One other issue I see is some keybinds throw a
"C-x <text-conversion> is undefined". Is this something other people are
seeing? Specifically C-x  h and C-x o

This actually only applies to software keyboards, not hardware, so there
must be some layer of translation happening from Android before it gets to
emacs.

I was seeing this problem too and I managed to fix it by using: -

(add-hook 'after-change-major-mode-hook (lambda () (set-text-conversion-style nil)))

There's a new section in the manual describing what "text conversions"
are and I used the information there to find out how to disable it. The
above hook is just a quick way to disable it in every buffer but I'm
sure it's just a workaround and that there's a better fix.

I hope that helps!

Kind regards,

Simon

Please show backtraces for all of those crashes.  The options menu works
here, so please show a backtrace from that too (`toggle-debug-on-error'.)

And, what keyboard are you using?

What keyboard are you using?  Text conversion should not happen when the
keyboard is sending ordinary prefix key events.

If you do this, your input method will no longer work properly.
It would be better to fix the individual keyboards to not perform text
conversion after a modifier key is pressed.

It happened with both Hacker's Keyboard and AnySoftKeyboard. I can't seem
to coerce it into entering the debugger since it's not truly an error.

I'll see about getting a trace.

No need, I will just disable text conversion while reading key
sequences.

When I click on Options it prints in backtrace buffer:

Debugger entered... : (void-variable scroll-bar-mode)
(eq scroll-bar-mode nil)

Just this.. Why it happens only with this menu item and not with the others.. Notice that File menu item and some other have a scroll-bar and they works...

When it crashes it closes I don't see anything.

Moko-atic Keyboard

Angelo, Simon, Jonathan: the Options menu and text conversion issues
should now be fixed on the branch.  I've uploaded a new prebuilt to
SourceForge as well, at the same URL as the old one.

Thanks for testing.

Thanks for looking into this issue. I've just rebuilt and tested and I 
can see that the problem is now solved for key sequences such as "C-h 
f".

However I use Evil and I also have trouble with using h,j,k,l to move 
the point in Evil's normal state. For example I would expect "j" to 
move the point down by one line (using `evil-next-visual-line') 
however when I press "j" in the Android version then I can see that it 
instead does the following: -

  <text-conversion> runs the command analyze-text-conversion (found in 
  global map), which is an interactive byte-compiled Lisp function in 
  'simple.el'.

Disabling text conversion with `(set-text-conversion-style nil)' 
allows those keys to function as expected.

You're welcome, happy to do so!

Yes, Options is fixed. Thanks.

Just for completeness, now when I press the DELETE key (on keyboard) in the minibuffer shows up this:

<KEYCODE_FOWARD_DEL> is undefined

This still occurs with the last emacs-30.0.50-21-arm64-v8a.apk.. to which "master" it refers?

BTW, in the init.el I have

;; Native buffer tabs setup
(global-tab-line-mode 1)

(setq tab-line-tabs-function 'tab-line-tabs-buffer-groups)
(setq tab-line-close-tab-function 'kill-buffer)

                    :inherit 'default)

and when I click tabs to switch/close buffers Emacs crashes (closes) more or less randomly...

Please show a backtrace from the crash.  If you run ``adb logcat'' and
wait for it to print everything, you can grep for:

  *** *** *** ***

the backtrace will follow the asterisks.

I do not have time to learn this , now.

Just for the record, today update fails systematically at start up...

You should get a backtrace if you want this to be fixed, because I can't read your mind (and your phone) from all the way over here.

Thanks.

How do you explain that with yesterday and today APK Emacs crashes at start up IF IT FINDS a desktop file?

I have in the init.el

(setq desktop-base-file-name "~/.emacs.d/desktop")

If I remove it (EShell), Emacs starts; if I quit it and save a desktop file (just when Emacs displays the scratch buffer), then re-launching it crashes, i.e. immediately closes. 

At least the previous APKs worked.. for a while

I don't know.  But I don't see any crash here.
I will ask some other people to try this.

Sorry for the late reply.

Does this port allow Emacs to access files outside app-specific
storage?  When trying the Sourceforge build, I was unable to access
files outside `/data/data/org.gnu.emacs`.  It looks to me the
application doesn't ask for any storage permissions.

Trying to use it with no a touch keyboard is not really efficient for
me (yet), but I didn't see any functions that would ask Android to
allow file system access.

I was surprised to see so many things working.  Thanks for your work.

Emacs does not ask for any permissions by default.  You must enable
access to storage on Android 10 and earlier, and access to ``All files
and media'' on Android 11 and later.  This is described in the Android
appendix of the Emacs manual, which I suggest you read.

Why is that?
The on-screen keyboard should be displayed whenever necessary.

Thanks.

The appropriate list for these questions is help-gnu-emacs@gnu.org,
which I've copied in.  That list is archived and is also gatewayed into
Usenet, so questions and answers sent there will benefit more people
than those directed to me personally.

I've never found it necessary, so patches welcome, I guess.  See
lisp/touch-screen.el.

That document has been moved to `java/INSTALL'.

Font shaping via HarfBuzz has been implemented and is now included in
all prebuilts for 64 bit architectures.  However, Emacs only supports
TrueType fonts, so I suggest installing the TrueType version Noto Sans
Arabic.

The procedure for installing fonts is described in (emacs)Android Fonts.

Emacs is now capable of running subprocesses regardless of system
restrictions, so you should be able to build

  https://github.com/termux/termux-packages/

with the prefix changed to `org.gnu.emacs', and to simply install
the resulting archives in Emacs's home directory.

Thanks for your interest in Emacs.  Fortunately, very little Android
specific knowledge is required to work on the Android port; a good
understanding of C and font scaling should be enough.

There it says we have to uninstall the current Android port and Termux. 

Really you mean we have to reinstall Termux from scratch with **ALL* packages we have installed for years? and their configurations and so on?

It is a request very heavy to follow..

Android doesn't allow updating packages with a different signature or
shared user ID.

If that's a concern, it's trivial to back up both files installed in
Termux:

  $ cd /data/data/com.termux
  $ tar cf /sdcard/termux.tar files

and the data from Emacs:

  $ cd /data/data/org.gnu.emacs
  $ tar cf /sdcard/emacs.tar files

before uninstalling both packages.

Hello,

Backing-up and restoring are described Termux-wiki,

https://wiki.termux.com/wiki/Backing_up_Termux

For me, it took an hour for tar and untar about 20GB data on
$PREFIX/{usr|home}.

Thanks,

OK, although there, the instructions look a bit different...

May be in Emacs we should have some documentation about this argument.

How to set up system package repositories is outside the scope of Emacs
documentation.

I have _really_ finished writing the Android port, and that includes a
new ``virtual filesystem'' component which enables Emacs to directly
edit (in contrast to merely reading) files and directories inside
document providers, such as network attached storage client programs.

No consensus was built the previous time we debated whether to include
this code or not, but with Emacs 29.1 out the door and master relatively
calm, I would like to revisit this subject.

I've already had gobs of people employ my inbox as a substitute for the
bug tracker, confirming my earlier apprehensions.  Furthermore, several
users have obtained my organizational e-mail by hook or by crook, and
used it for petty banter concerning design and UI decisions made there,
leading to unpleasant inquiries from my management regarding the
adequate use of organizational resources.  As such, I hold no continued
interest in _publishing_ updates to this port, unless it is clearly
presented as part of GNU Emacs instead of a one man show.  Judging by
the abundance of discourse misdirected at me, it seems to interest more
than a negligible portion of the Emacs user populace, some of whom use
the branch for its improved touch-screen support outside of Android.

Also, would someone ascertain if the branch still builds on MS Windows,
after the past few updates from Gnulib?

TIA.

There's no need to revisit, from where I stand.  It is quite clear
this community as a whole thinks that having the port as part of Emacs
is more important than the potential difficulties and issues it could
create.

Once Someone™ confirms that the MinGW and NS builds work on that
branch, you can go ahead and land the branch on master.  (But please
be sure to make a proper log message naming all the new files and
changes in existing ones, when you merge.)

And a huge thanks for working on this port.

Thanks everyone for your support as well.  And please, direct comments
and questions to the Emacs development lists, and _not_ my inbox.

Is asprintf used in any code that needs to be run in the MS-Windows
build of Emacs?  If not, then the easiest solution is to disable
building Gnulib's asprintf via nt/gnulib-cfg.mk.

configure?

No, the Gnulib folks added two new checks to vasnprintf.m4 reflecting
new C2X features, that weren't present the last time I fixed the Windows
build.

If MinGW doesn't support those directives, the above is not TRT, it
might cause future maintenance headaches.

I don't think MSVCRT.DLL's implementation of printf supports those, at
least not on all versions of Windows.

That doesn't answer my question, AFAICT.  In the current master we
have no uses of asprintf and vasnprintf, so I asked whether it is
needed on the branch, and if so, whether the MS-Windows build uses the
code where these two functions are called.

The way to override Gnulib tests that conclude that some libc function
should be replaced is not to override the feature test (unless that
feature is supported, but Gnulib doesn't know about it -- which can
only happen if we implement the library function inside Emacs).  The
way to override those is to exclude the relevant Gnulib modules from
the Windows build via nt/gnulib-cfg.mk.  If that is not appropriate,
i.e. if the Gnulib module _is_ actually required in the MS-Windows
build, then this is a Gnulib bug that should be reported to them and
fixed by them (but in that case you cannot merge the branch until the
Gnulib folks provide the fix).

Those flags are how Gnulib users are meant to disable the printf-posix
module, though.  Angelo, would you please provide your config.log?  It
would assist me in determining which printf features Gnulib is still
striving to replace.

It doesn't, but vfprintf-posix actually replaces all the printf
functions, not just (vasn)printf.  The replacement functions are not
necessary on Windows, however.

There is already:

OMIT_GNULIB_MODULE_vasnprintf = true
OMIT_GNULIB_MODULE_vasprintf = true
OMIT_GNULIB_MODULE_vfprintf-posix = true

within gnulib-cfg.mk, but fudging with the feature tests is also
necessary to generate the Gnulib stdio.h header correctly; absent that,
it tries to provide definitions for its printf replacements, which does
not work.

IIRC manipulating the feature tests in such a fashion was proposed by
one of the Gnulib developers when the W32 build was last tested in
March, but my memory of that is indistinct and I might've read this
elsewhere.

Then TRT is to disable the build of vfprintf-posix module on Windows.

OK, then I guess there's something else at work here.  In any case,
the information posted by Angelo clearly shows that asprintf.c is
being compiled, and that is strange if vfprintf-posix module is
disabled.  Maybe we also need

  OMIT_GNULIB_MODULE_asprintf = true

?

There's no module by that name; asprintf is a constituent of vasnprintf,
and that's already mentioned in gnulib-cfg.mk...

With both patches applied I'm able to build feature/android under
MSYS2/MinGW64.  I am trying a 32 bit build now.

When why is asprintf.c being compiled, if its module is disabled?
Disabling a module should disable the lib/Makefile rules that compile
the module.

What feature does the gl_cv_func_printf_sizes_c23 variable test?  Does
MinGW printf indeed support that feature?  If not, we are lying to the
configure script, and that is not TRT.

Because the Gnulib configury includes it within LIBOBJ:

AC_DEFUN([gl_REPLACE_VASPRINTF],
[
  AC_LIBOBJ([vasprintf])
  AC_LIBOBJ([asprintf])
  AC_REQUIRE([gl_STDIO_H_DEFAULTS])

whenever it detects that asprintf isn't present on the host system.

Gnulib doesn't support disabling these modules through Makefile options.

We are deceiving the configure script, but that's the only ``supported''
way to disable the printf* modules, as they aren't subject to the normal
Make-based controls in gnulib.mk.

That build also succeeded; I can run the resulting runemacs.exe from
MinGW32; it "works".

What is gl_REPLACE_VASPRINTF, and why is it set for MinGW?  Can that
be disabled somehow (without setting configure variables that test
specific features)?

Then we should ask them to add that, or help us solve this in another
proper way.

Paul and Bruno, can you please advise how to resolve this issue?  We
need to disable the compilation of these *printf modules on
MS-Windows, since the Windows build doesn't need them, and compiling
them causes compile-time errors.  The usual method of omitting a
module, like we do in nt/gnulib-cfg.mk, seems not to work in the above
case for some reason.

Another possible way forward is for Gnulib to modify asprintf.c so
that it does compile with MinGW (and then it will be left unused on
Windows in libgnu.a).

TIA

I'm sorry, but such a solution is not acceptable, as it will be a
maintenance headache, if and when we actually need these features in
Emacs.  We must find a cleaner solution.

Let's wait for the Gnulib folks to chime in and suggest better ways of
solving this.

On which version of MS-Windows did you test the 32-bit build?

And thanks for yours and Angelo's efforts in validating this branch.

gl_REPLACE_VASPRINTF is a macro that is expanded into configure.ac by
gnulib-comp.m4, and acts upon the results of the aformentioned printf
tests.

AFAIK, lying to configure _is_ the proper way for this specific
module...

I have Windows 10 Home (22H2) OS Build:19045.3271
On the off chance it helps, I have Windows Feature Experience Pack
1000.19041.1000.0

I launched Emacs (in my x64 bit environment) from:

MINGW32_NT-10.0-19045 Avalon 3.3.4-341.x86_64 2022-02-15 17:24 UTC x86_64 Msys

The last android branch builds on NS (macOS 10.13.6 HS).

Anyway I discovered an issue with this branch, both on Windows (yesterday build) and NS (today build), when upgrading packages.

 M-x list-packages
 U
 x

it fails: in the minibuffer I get

[y-or-n-p:] Symbol’s function definition is void: set-text-conversion-style


With current master it works as expected...

Before thinking about how to disable things, the first thought should
be how to fix the compilation error — since that's generally easier
and also may help other packages than Emacs.

This asprintf() declaration in mingw's <stdio.h> is guarded by
__USE_MINGW_ANSI_STDIO. I've checked the Emacs source code, and it
appears to set __USE_MINGW_ANSI_STDIO to 1, just like Gnulib does.

Therefore I need more info from the reporter (Angelo [1]), for analysis:

1) Please do "make -k V=1" twice and attach the log of the second run.
   (Logs without V=1 often hide important details. Also, I'd like to
   know whether the same error also occurs with vasprintf.c.)

2) Please attach the file config.status. I need to the see value of
   REPLACE_ASPRINTF and related variables.

3) Also, if you still have the output of 'configure' (the many
   "checking for ..." lines), it would be good if you could attach
   that as well.

4) Finally, please attach the C:/msys64/mingw64/include/stdio.h — because
   there are so many versions of mingw.

Thanks.

I had lost that source but 

wget https://git.savannah.gnu.org/cgit/emacs.git/snapshot/emacs-bfbdf4eb892935536fc665d6cc986fd669364263.tar.gz

seems the same source. It has the same failure.

The attached tarball contains:

- autogen_configure_output.log, which is the output of
  
    ./autogen
    ./configure

- make-k_V.eq.1-first_output.log, which is the output of the first `make -k V=1`
- make-k_V.eq.1-second_output.log, which is the output of the first `make -k V=1`
- config.status
- stdio.h (/mingw64/include/stdio.h)

Thanks. The REPLACE_*PRINTF values appear to be correct.

But from this error log:

In file included from C:/msys64/tmp/emacs-bfbdf4eb892935536fc665d6cc986fd669364263/nt/inc/ms-w32.h:389,

                 from ../src/config.h:3511,
                 from printf.c:18:
C:/msys64/mingw64/include/stdio.h:379:5: note: previous definition of 'printf' with type 'int(const char *, ...)'

it seems that nt/inc/ms-w32.h directly includes <stdio.h> from mingw, without
the interposed lib/stdio.h.

Do you have a lib/stdio.h in your build tree?

The MinGW build omits building the Gnulib's stdio module.  We did that
since 2017.  The exact reasons are probably lost in time, but I can
assure you they were real, and I wouldn't want to reintroduce them for
this particular reason.

Since the *printf family doesn't need to be replaced in the Emacs
build on MS-Windows, I'd rather we understood why the above causes
compilation errors.  Aren't Gnulib replacements for *printf functions
supposed to have prototypes compatible to the MinGW headers?

Judging from the headers Angelo provided, the issue lies in MinGW's
headers defining (not merely declaring) asprintf:

#ifdef _GNU_SOURCE
__mingw_ovr
__attribute__ ((__format__ (gnu_printf, 2, 3))) __attribute__((nonnull (1,2)))
int asprintf(char **__ret, const char *__format, ...)
{
  int __retval;
  __builtin_va_list __local_argv; __builtin_va_start( __local_argv, __format );
  __retval = __mingw_vasprintf( __ret, __format, __local_argv );
  __builtin_va_end( __local_argv );
  return __retval;
}

IMHO, the least risky solution remains disabling the vasprintf module
entirely.  We can revisit this problem when and if Emacs begins to rely
on ISO C2X and C99 features supplied by Gnulib.

Angelo replied "It seems no".

And that is the problem. The generated stdio.h, on this platform, is
supposed to contain macro definitions:
  #define asprintf rpl_asprintf
  #define printf __printf__
  #define vasprintf rpl_vasprintf
  #define vfprintf rpl_vfprintf

By omitting these macro definitions, there is a conflict between the
inline definition in mingw's <stdio.h> and the Gnulib replacement code.

It'd be worth a try nevertheless. Gnulib has changed a lot since 2017.

See above.

> Aren't Gnulib replacements for *printf functions
> supposed to have prototypes compatible to the MinGW headers?

No, Gnulib replacements always have different function names than
the system function (except for the 'free' function). The reason
is that there is so much variation in the prototypes of a function
(with or without 'restrict', with or without 'throw()' in C++,
with or without 'static' / 'inline'), that it would be extremely
fragile to attempt to get the exact same prototype as the system.

So, if you decided not to have a generated stdio.h, the simplest
solution seems to be:
  1) in the conf_post.h or nt/inc/ms-w32.h, include <stdio.h>
     (this is the one from the system),
  2) after this #include, add
     #define asprintf rpl_asprintf
     #define printf __printf__
     #define vasprintf rpl_vasprintf
     #define vfprintf rpl_vfprintf
     and add prototypes for these 4 functions.

I agree.  We wanted to do that from the get-go, but you said it was
somehow impossible, or didn't work?

That's the subject I'm trying to bring up with Bruno: presently, it's
still impossible to disable printf-related using the
`OMIT_GNULIB_MODULE_' Makefile options, only through manipulating test
results in mingw-cfg.site.

If someone wants to try that and report back, I won't mind.  But I
personally don't have time (nor the motivation, TBH).  There be
dragons: for example, Emacs on MS-Windows provides its own
implementation of fopen, because we want to support UTF-8 encoded file
names even when the system codepage is not (or cannot be) UTF-8.
Likewise with any other Gnulib replacement that accepts file names:
Emacs must be able to pass UTF-8 encoded file names on Windows,
because it supports non-ASCII file names without restrictions imposed
by the current system codepage.

I'd prefer to use the simpler machinery of OMIT_GNULIB_MODULE to
prevent the Emacs build from compiling asprintf.c and similar
replacements on MS-Windows.  Is that possible?  We do that with
several other Gnulib modules, see the file nt/gnulib-cfg.mk in the
Emacs repository.

Thanks.

Only Paul can answer this. The OMIT_GNULIB_MODULE mechanism is an Emacs
invention.

Gnulib's mechanism for avoiding modules is the --avoid=<modulename>
option to gnulib-tool. But that omits the module on *all* platforms.
Gnulib's preferred mechanism for tweaking the behaviour on a platform-
by-platform basis is to preset some gl_cv_* variables, so as to
shortcut specific configure tests.

I prefer not to preset gl_cv_* variables in this case, since they are
general enough tests of specific printf features, and if those
features will ever be really needed in Emacs, we want to be alerted to
that.  We only preset such variables when the corresponding features
are implemented in Emacs's own code (about which the configure script
cannot know), or when it is clear that the features will never be
useful in Emacs on Windows.

I don't follow this: even if these tests are left intact, how will they
serve to warn us of new dependencies introduced in Emacs?  The results
of the configure tests are irrespective of Emacs source code.

The results of those tests are logged in config.log.  When we preset
the variables, the tests are not performed and the results are not
recorded anywhere; you just see something like "(cached) yes".

And in addition, other tests for other Gnulib modules might depend on
the results of these tests.

If so, those Gnulib modules will also depend on the *-printf modules, by
all likelihood.  Our attention will be brought to the problem regardless
of how we chose to disable those modules.

It will be harder to figure out, at least.

Look, I'm the only person around here who had ever seriously worked
with these facilities, so please believe me when I say that some ways
are better than others, okay?

OK, but the Gnulib developers aren't inclined to introduce any changes
for us here.  So we've got to work with what we have, following practice
that already exists within mingw-cfg.site:

# We don't need fdopendir
ac_cv_func_fdopendir="not-needed"
gl_cv_func_fdopendir_works="no-but-not-needed-so-yes"

# Avoid gnulib replacement
gl_threads_api=posix
gl_cv_func_pthread_sigmask_return_works=yes
gl_cv_func_pthread_sigmask_unblock_works="not relevant"
gl_cv_func_pthread_sigmask_macro=no

Paul didn't chime in yet, so I'd like to wait for him to comment on
this.  I see no reason why we would be unable to omit these modules
like we do with others.

There are good reasons for those (and others like them).  fdopendir is
not a feature, it's an API that cannot work on Windows.  And the
pthreads stuff causes Emacs to depend on the pthreads DLL (which is
bad for distributing the binaries), and also replaces some
time-related structure definitions ('struct timespec', I think) with
pthread ones -- and these cannot be undone by omitting some Gnulib
modules.

Like I said: this stuff is done for very good reasons, and only after
careful consideration of the alternatives.  It worked for the last 10
years with almost no changes.

I don't either, but I hope we don't have to worry about it.

As I understand it the Android port uses Gnulib printf-posix and 
vasprintf-posix modules only because Android printf lacks support for 
"%td", "%jd" and "%ju". If this understanding is correct, how about if 
we go through the printf formats in the Emacs C source code, and replace 
all uses of "%jd" and "%ju" with "%"PRIdMAX and "%"PRIuMAX, and all uses 
of "%td" with "%"pT"d" where pT is an Emacs invention defined like this:

  #ifdef __ANDROID__
  # define pT "z"
  #else
  # define pT "t"
  #endif

That way, the Android branch wouldn't need to use the printf-posix and 
vasprintf-posix modules, and we wouldn't have to worry about the hassle 
of porting them into the Emacs world.

Admittedly this hack is not the Gnulib Way, but Emacs departs so far 
from the Gnulib Way that this one extra little thing shouldn't be that 
big of a deal.

Fine by me, if this keeps the Android port happy.

Most of those are not relevant for Android, right?

The only one which is relevant (in emacs.c) can be rewritten not to
use %n.

No need for the air-quotes, it is quite justified (and could probably be
backed up more empirically if someone went over something like the
Debian code-search).

In my many years of writing and reading C on all levels, I've seen %n
used outside of arbitrary memory write exploits at most a handful of
times.

Indeed, but the Proper Way is to use Gnulib.  I'd prefer we tried to
make it work.

Thank you for your input, but please keep irrelevant tangents out of
this discussion.  We want to merge the Android branch as soon as
possible, and converting this into yet another futile dispute about
security will get in the way of finding the best solutions.

If you can figure out why omitting those modules doesn't work, maybe
we could go that way as well.

I thought I did.  Paul, the issue lies in how AC_LIBOBJ is used to
include the files comprising the *printf modules.  The
OMIT_GNULIB_MODULE_xxx stuff cannot function unless gnulib.mk does so
instead.

You said that those files are included in the list of object files to
build if Gnulib configury detects that asprintf is missing, right?

Then I don't think I understand this, since (a) MinGW64 which Angelo
uses does have asprintf, and (b) we could use the configure variable
that records the existence of asprintf to override that, like we do
with other ac_cv_func_* variables.  But for some reason you didn't use
that variable (or any similar one) in your proposed patch, why?

So to me this issue is still not clear enough.

That's because my patch was an addendum to changes installed on the
feature/android branch months ago.  The diff between mingw-cfg.site on
the branch and on master is more illustrative:

diff --git a/nt/mingw-cfg.site b/nt/mingw-cfg.site

Both the check for vasprintf (Gnulib eschews testing for asprintf, since
asprintf is never present where vasprintf is not) and the checks for
printf features are overridden, because Gnulib also tries to replace
vasprintf if it discovers that the conventional printf functions will
need to be replaced.

No, that's not the case. Android *printf supports the 't', 'j', 'z' already
since 2009-03-04 (ca. Android 1.6).

I don't know what's the minimum supported Android version targetted by Po Lu
is, but for Android 4.3 you find the deficiencies listed in gnulib/m4/printf.m4:

dnl . = yes, # = no.
dnl
dnl                                  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
dnl   Android 4.3                    .  #  .  #  #  #  #  #  #  #  #  ?  .  #  .  #  .  #  .  .  .  #  .  .

Legend:
dnl 2 = checking whether printf supports size specifiers as in C23...
dnl 4 = checking whether printf supports infinite 'double' arguments...
dnl 5 = checking whether printf supports infinite 'long double' arguments...
dnl 6 = checking whether printf supports the 'a' and 'A' directives...
dnl 7 = checking whether printf supports the 'b' directive...
dnl 8 = checking whether printf supports the 'B' directive...
dnl 9 = checking whether printf supports the 'F' directive...
dnl 10 = checking whether printf supports the 'n' directive...
dnl 11 = checking whether printf supports the 'ls' directive...
dnl 12 = checking whether printf supports the 'lc' directive correctly...
dnl 14 = checking whether printf supports the grouping flag...
dnl 16 = checking whether printf supports the zero flag correctly...
dnl 18 = checking whether printf survives out-of-memory conditions...
dnl 22 = checking whether snprintf fully supports the 'n' directive...

This workaround is not needed, since the problem is not there, not for
Android and not for other platforms either: Gnulib's documentation lists
the platforms

  @item
  This function does not support size specifiers as in C99 (@code{hh}, @code{ll},
  @code{j}, @code{t}, @code{z}) on some platforms:
  AIX 5.1, HP-UX 11.23, IRIX 6.5, Solaris 9, Cygwin 1.5.24, mingw, MSVC 14.

AIX 5.1, HP-UX 11.23, IRIX 6.5, Solaris 9, Cygwin 1.5.24 are long obsolete,
mingw is dealt with by Emacs differently, and MSVC is not supported by
Emacs (AFAIU).

Isn't there some "summary" variable for printf, like
gl_cv_func_printf_works or some such, which is set if all of the above
variables are set?  I'd prefer to override summary if it exists,
rather than each one of the above function-testing variables
individually.

Perhaps we should ask Gnulib to allow disabling these in a more
convenient manner.

Then I would suggest to rewrite this instance without %n.

Rationale: I cannot guarantee that Gnulib will be able to support %n
in the long run. The "security-aware community" are filing CVEs here and
there; %n is among their targets (it has already been disabled from libc
on Ubuntu, macOS, and MSVC); and I don't know when they will discover
that Gnulib still enables it.

No, there is no such "summary" variable. And it would be overkill to
introduce one, because
  - Emacs is the only package that needs a certain Gnulib module on
    most platforms but wants to deactivate it on one particular platform.
    Other packages don't work this way.
  - The approach to set the variables individually in mingw-cfg.site
    is good enough. It occasionally needs updates, every N years or so,
    when some variable is added. But that's not a good enough justification
    for adding complexity to Gnulib.

Also, a "summary" variable would not fulfil the goal that you set out
yourself yesterday:
  "I prefer not to preset gl_cv_* variables in this case, since they are
   general enough tests of specific printf features, and if those
   features will ever be really needed in Emacs, we want to be alerted to
   that."

I perfectly understand this argument, that you want to be aware if the
mingw-cfg.site file for example pretends that Emacs does not need %b support,
in order to check the format strings to see whether that's indeed the case.
The individual gl_cv_* variables are the right instrument to achieve this
process.

There is a patch for this already in the OpenBSD ports tree:

Thanks, but unless they contribute the code to us, pointing to that
code here is actually discouraged: it makes harder for people to write
an independent implementation that cannot be possibly taken as a copy
of theirs.

Rewriting this without %n is basically trivial.

The decision whether Emacs's needs justify some additional complexity
in Gnulib is yours, of course (although I'd argue that Emacs is not
just any package), but please don't decide for the Emacs maintainers
whether this or that alternative is "good enough" for Emacs.  If we
reach out to Gnulib developers asking them for help in this matter, we
do that in good faith, and _after_ we considered the alternatives
which don't involve Gnulib changes (which are always preferable, for
obvious reasons).

Unless there's a misunderstanding, your understanding contradicts what
I wanted to convey in the quoited text.  The individual gl_cv_*
variables, if overridden by mingw-cfg.site, will completely shadow the
feature tests and will from that moment on make detecting any new
needs for that and dealing with those new needs our responsibility,
with nothing to aid us.  Which in practice means we could have a
broken port on Windows if some other functionality, which _is_ needed
on Windows, will become dependent on a test that we've overridden via
these variables.

Which is why I prefer to disable a module or a function replacement
without overriding the individual functionality tests which led to the
inclusion of the module and/or replacement of a function.  Disabling
the module or a function replacement just says that this
module/function is not needed or is implemented differently, without
saying anything about the respective functionalities.

Disabling functionality tests is only TRT when they are implemented in
Emacs's own code (and thus the configure script cannot possibly know
about them).  And even then we try to minimize the list of disabled
functionalities by telling the configure script as much as we can;
that is the reason why the configure script does this:

      *-mingw* )
                opsys=mingw32
                # MinGW overrides and adds some system headers in nt/inc.
                GCC_TEST_OPTIONS="-I $srcdir/nt/inc"

Then Gnulib should disregard their whims and move on.  If a program
employs %n incorrectly, and that exposes a security vulnerability as a
result, the fault lies with the authors of said program rather than
Gnulib.

Android 2.2.

That being said, I'm reluctant to remove the printf-posix module at this
stage of the port's development.  Emacs has undergone extensive testing
on all supported versions of Android with the Gnulib printf, and hardly
any at all without.

I think what Bruno tells us is that removing %n where it is not
strictly needed is a good way of eliminating the cause for both
problems.  We may not agree with CVEs against %n, but we won't keep %n
just because we disagree, right?

Is there a way of running specific Gnulib tests only on some
platforms (without setting the gl_cv_* variables)?

Everyone,

This conversation is fast on track to becoming unmanageable.  Since the
Gnulib developers believe that the solution presently in place on the
branch is acceptable, and it _does_ work to the best of our knowledge,
how about merging the branch and shelving this conjecture for the time
being?  Personally, I feel that it's unlikely that any other Gnulib
module we import will make use of the test results that are overridden,
as the printf modules are self-contained.  We can always assess the
impact of future changes to Gnulib when they are merged into Emacs.

Thanks.

I understand your POV, but I would like to give this discussion some
more time before we make the decision.  We do want to merge the
branch, but a day or two more while we discuss alternatives won't
change anything.

In other words, you want to use the printf-posix module on Android but
not on mingw.

Your question makes me think of a way to use a module on one platform
but not on another platform. Namely, the Emacs' invocation of gnulib-tool
already contains --conditional-dependencies (see emacs/lib/gnulib.mk.in).
Combine this with the feature explained in
https://www.gnu.org/software/gnulib/manual/html_node/Extending-Gnulib.html

1) Add a file emacs/gnulib-local/modules/printf-for-emacs with the following
   contents:

=========================================================================
Description:
POSIX compatible printf() function on selected platforms.

Depends-on:
printf-posix     [case "$host_os" in mingw*) false;; *) true;; esac]
=========================================================================

   What this does is to add a module with a conditional dependency to
   'printf-posix'.

2) In the gnulib-tool invocation, add the option --local-dir=../gnulib-local
   (so that it references the emacs/gnulib-local/ directory), and add
   the module 'printf-for-emacs' to the module list.

I believe this solution will work unchanged for 10 or 20 years.

Please don't post these changes here, unless their authors have agreed
(and signed the paperwork) necessary to distribute them with Emacs!

Now that we can be construed to have read them, we must go out of our
way to make our code dissimilar, should we ever want to perform the same
modification.

According to my reading of vasprintf.m4, if ac_cv_func_vasprintf=yes,
the rest of the tests, including adding asprintf to LIBOBJ, should not
have happened:

  AC_DEFUN([gl_FUNC_VASPRINTF],
  [
    AC_CHECK_FUNCS([vasprintf])
    if test $ac_cv_func_vasprintf = no; then  <<<<<<<<<<<<<<<<<<
      gl_REPLACE_VASPRINTF
    fi
  ])

Or, if we are using vasprintf-posix.m4 (are we?), then
gl_cv_func_vasprintf_posix should have done that:

  AC_DEFUN([gl_FUNC_VASPRINTF_POSIX],
  [
    AC_REQUIRE([gl_FUNC_VASPRINTF_IS_POSIX])
    if test $gl_cv_func_vasprintf_posix = no; then <<<<<<<<<<<<<<<<<<<
      gl_PREREQ_VASNPRINTF_WITH_POSIX_EXTRAS
      gl_REPLACE_VASNPRINTF
      gl_REPLACE_VASPRINTF
    fi
  ])

I see that gl_cv_func_vasprintf_posix is not in your patch to
mingw-cfg.site, so maybe adding that is all that's needed to avoid
overriding all the other gl_cv_func_printf_* variables?

PS: The differences between this approach and the OMIT_GNULIB_MODULE_*
approach (as far as I understand it) are:

* This approach uses only documented Gnulib features.
  Whereas the OMIT_GNULIB_MODULE_* approach hacks generated files and
  is thus more fragile.

* This approach has an effect on both the set of .m4 code executed by
  configure _and_ the generated Makefiles.
  Whereas the OMIT_GNULIB_MODULE_* approach does not change what happens
  at configure time, it only modifies the generated Makefiles.

Paul, please correct me if that is not correct?

There are invocations of gl_REPLACE_VASPRINTF from other places as well.
This is why we couldn't turn the AC_LIBOBJ invocation into a lib_SOURCES
augmentation in the module description. (It would yield duplicate symbols
at link time, in some circumstances.)

Yes (assuming it works: that remains to be seen).  But: (a) I'd like
to hear Paul's opinion on this solution, since he is the one who
routinely imports Gnulib into Emacs; and (b) I'd like to see if
setting gl_cv_func_vasprintf_posix=yes in mingw-cfg.site (in addition
to ac_cv_func_vasprintf, if needed) will disable the compilation of
the *printf modules and solve the problem in a way that is simple and
doesn't require introduction of any new infrastructure into Emacs.

Only 2 more, AFAICT, and we only care about those whose modules we

It's possible that I had misunderstood you. In fact, I don't fully

I'd like to view this question from the process point-of-view:

If some new functionality test is introduced in gnulib/m4/printf.m4,
be it
  (a) because a bug has been discovered on a non-mingw platform
      (such as recently the %lc bug), or
  (b) because a bug has been discovered on mingw, or
  (c) because a new ISO C or POSIX standard requires new functionalities
      (such as recently the support of %b),
what do you expect to see and do in Emacs?

In all three cases, we update the Gnulib documentation, but don't put
an entry into gnulib/NEWS.

Will you typically want to
  - review all format strings in Emacs, to see whether they are affected?
  - add some note to Emacs-internal coding guidelines, e.g. to the effect
    that %b should not be used?
  - review the mingw-specific *printf override, to see whether it
    needs a workaround (in case b) or an extension (in case c)?
  - or do nothing at all?

First, the above is only about the MinGW build of Emacs.  We don't
override Gnulib tests and their results on any other platforms
supported by Emacs and by Gnulib.  The reasons for this special
treatment of Gnulib on MinGW are:

 . Emacs supports old versions of Windows while Gnulib dropped their
   support, so we cannot use Gnulib functions which will fail on those
   older Windows versions (e.g., because Gnulib assumes some API to be
   always present which is not available on old Windows versions, or
   needs to be manually loaded from some DLL);
 . Emacs supports UTF-8 encoded file names by converting them to
   UTF-16 and using "wide" APIs to access such file, something Gnulib
   doesn't support AFAIK, except when the system codepage is UTF-8;
 . Emacs sometimes have special needs which require emulation of
   certain APIs in a way that is different from what Gnulib does
   (examples: getloadavg and ACL functions)

With the above in mind:

Not relevant to this discussion: non-MinGW platforms will get what
Gnulib provides.

>   (b) because a bug has been discovered on mingw, or

Depends whether this bug is relevant to Emacs, and whether the
relevant Gnulib functions are already used in Emacs on Windows.  If
the latter, we will simply use the updated Gnulib function.
Otherwise, it might need changes to Emacs's own code to work around or
fix the bug.

If this is needed in Emacs, and in code that is used in the MinGW
build, we'd need to wait until __USE_MINGW_ANSI_STDIO will support the
new functionality, or provide some workaround in Emacs's code, or
declare that the relevant feature doesn't work in the MinGW build.  A
good example of this is the time-related functions in Emacs: we don't
support time-zone specifications of the form "Asia/Seoul" because the
Windows time-zone functionality cannot grok that.

Some mix of the above, depending on the case.  But only for the MinGW
build.

Btw, the problem with printf* is exacerbated because Gnulib pulls in
the entire stdio.h when it needs to replace some printf*
functionality, and stdio is a huge header/module with some functions
that we cannot allow to override in Emacs, due to the aspects I tried
to describe above.  Fortunately, Emacs needs printf* in only a handful
of places, and for very narrow functionality.

On top of previous, I think.  In any case, you are supposed to be left
with just these two, under the "Don't build gnulib printf either"
comment:

  # Don't build gnulib printf either.
  ac_cv_func_vasprintf=yes
  gl_cv_func_vasprintf_posix=yes

Thanks.

OK. How do you reliably get notified about the relevant changes?
If you look at gnulib/ChangeLog and search for "mingw" or "Windows"
you will spot some of the relevant changes.

For more reliability, I would save the generated config.cache from a mingw
build somewhere, and compare the config.cache of newer builds with the
saved one. If you see an added gl_cv_* variable or an existing one
whose value has changed, you can raise your eyebrows. So, it makes
sense to override only the mimimum of gl_cv_* variables.

However, this approach would still have its potential gaps:
In case
> >   (b) because a bug has been discovered on mingw

Gnulib might stuff the new configure test into an existing AC_RUN_IFELSE
invocation and thus reuse an existing gl_cv_* variable. (Not for *printf,
but for other modules.) Say, gl_cv_foobar_works meant the absence of
bugs P and Q, and now it means the absence of bugs P, Q, and R. When
the override gl_cv_foobar_works=yes was added, it meant "our nt code
has workarounds for P and Q". Thus, you won't be alerted that you need
to add a workaround for R or remove the override gl_cv_foobar_works=yes.

If you were to build the corresponding gnulib tests as part of the Emacs
build (gnulib-tool option '--with-tests'), then we would have added a unit
test against bug R, and this test would fail, thus alerting you that
you need to do something.

Note: Since the gnulib-tool invocation includes many '--avoid' options,
some test failures are to be expected, until these tests are '--avoid'ed
as well.

I have not read those patches. I wrote the attached patch myself and 
installed it into the master branch, so we don't need to worry about 
printf %n for Android.

Although I don't know whether the attached patch is dissimilar to the 
OpenBSD patches that I haven't read, it's surely dissimilar emough, as 
the attached patch uses sprintf (safely) and the OpenBSD folks are 
allergic to sprintf.

Are you sure you did all the steps starting from autogen.sh and
running the configure script?

If yes, it means something else causes asnprintf.o to be added to
LIBOBJ.  What does the below show in the m4 directories (I think there
are two of them on the Android branch):

  $ grep 'gl_REPLACE_VASN\?PRINTF' *.m4

Thanks.

By watching the Gnulib updates and new Gnulib modules that get
imported and compiled into libgnu.a.

I do that as well, when I suspect some change could cause a

The foobar function (or its emulation) needs to do its job on
MS-Windows well enough for us to set gl_cv_foobar_works=yes.  If it
doesn't, and Gnulib discovers that first (unlikely, but possible), we
will have to pick that up in some way, either by watching Gnulib
updates, or via user complaints, or in some other way.

Luckily, this happens very rarely, IME, at least as far as things
related to Emacs on Windows are concerned.

Emacs doesn't (yet) have a facility to run Gnulib tests.

I understand the reluctance from the Android point of view. However, 
printf-posix imports 69 new source files to Emacs, and these files have 
not been tested extensively with Emacs on non-Android platforms. From 
the viewpoint of non-Android Emacs platforms, it's significantly less 
disruptive if merging the Android branch does not add 69 new source 
files that will require testing on these platforms.

And even from the Android viewpoint, no matter what we do to fix the 
problem some testing needs to be done anyway, as the fix is likely to 
affect Emacs in test-relevant ways.

So I propose that we merge the master branch into feature/android (to 
get the recent fix to stop using %n) and then apply the attached 
patches. The first and third patches are the actual idea. The second 
patch (compressed to save space) is automatically generated via 
admin/merge-gnulib, and consists of deleting the 69 source files.

The idea is to get feature/android merged quickly. We can revisit the 
use of Gnulib's printf-posix module later, as needed. With luck 
printf-posix won't be needed, as Emacs historically has avoided use of 
unusual printf features (for obvious portability reasons).

I think Paul makes a good point here about those modules not being
tested in Emacs on other platforms.  Avoiding addition of 69 files to
Emacs is also a non-trivial gain.

Since Emacs 30.1 will not be released any time soon, I think we will
have ample time to test it without the *printf modules, and find out
and fix any issues this could create.

So I suggest to give this solution a chance.

Thanks, Bruno, this sounds like a promising idea. I'll add it to my list 
of things to do for Emacs. I'm hoping that it isn't needed for merging 
the Android port, though, as it'll require some thinking and testing of 
its own.

I agree: this is certainly something to consider for the future, but
it is better kept separate from the prerequisites for merging the
Android branch.  The main "beneficiary" of migrating to this method is
the MinGW build (and the Gnulib import job), not the Android build.

So I think we need to set 3 more variables:

 gl_cv_func_printf_posix=yes
 gl_cv_func_vfprintf_posix=yes
 gl_cv_vasprintf_posix=yes

I did a quick try. Added manually the above lines to mingw-cfg.site file, reconfigured and 'make', but it fails as described..

Sorry, one typo and one more variable:

  gl_cv_func_printf_posix=yes
  gl_cv_func_vfprintf_posix=yes
  gl_cv_func_vasprintf_posix=yes
  ac_cv_func_vasnprintf

OK, it sounds like this part of the interface between Gnulib and Emacs
development works well enough in practice? If you agree, then I'm glad
nothing needs to be changed on the Gnulib side in that respect.

It works well enough, yes.  The number of times the build was broken
since we moved to using the Posix configury on Windows 10 years ago is
less than a dozen, I think.  Which is pretty fabulous, IMO.

Now:

$ tail nt/mingw-cfg.site
# Suppress configure-time diagnostic from unnecessary libxattr check,
# as xattr will not be supported here.
enable_xattr=no
# Don't build gnulib printf either.
ac_cv_func_vasprintf=yes

gl_cv_func_printf_posix=yes
gl_cv_func_vfprintf_posix=yes
gl_cv_func_vasprintf_posix=yes
ac_cv_func_vasnprintf


but I am afraid, it still fails...

I plan to quickly test this on some old versions of Android and ack.

Cursory inspection indicates that Emacs functions correctly without the
*printf modules on Android 2.3, 4.0.1 and 4.4, so I've ommitted the
modules and merged the branch to master, after removing the w32-specific
code that disables them.

Thanks for your help.

The last one should be

  ac_cv_func_vasnprintf=yes

Anyway, thank you for your efforts.

It works, since the printf module has been removed.

Actually, it's partially my fault: I made a mistake in my fix of
Eric's changeset.  I hope it's fixed now on master.

Thanks.  It looks like nt/gnulib-cfg.mk still names modules that were
eventually removed?  Could you please audit the modules added to
gnulib-cfg.mk and remove the lines that are no longer needed on
master?

Also, it looks like neither ENABLE_CHECKING nor GLYPH_DEBUG are being
defined in src/config.h in the non-Android builds, although I passed
the --enable-checking-'yes,glyphs' option to the configure script.
This has something to do with this snippet of configure.ac:

  AS_IF([test "x$XCONFIGURE" = "xandroid" \
	 && test "x$android_enable_checking" = "xyes"],
    [ac_enable_checking=yes])

  # There is little point in enabling checking in the build machine if
  # cross-compiling for Android.
  AS_IF([test -z "$with_android" || test -n "$XCONFIGURE"],[
    if test x$ac_enable_checking != x ; then
      AC_DEFINE([ENABLE_CHECKING], [1],
    [Define to 1 if expensive run-time data type and consistency checks are enabled.])
    fi

It generates the following code in configure:

  # This environment variable is used to signal that checking should be
  # enabled on Android.  When that happens, simply enable checking for
  # the cross-compiled Android binary.

  if test "x$XCONFIGURE" = "xandroid" \
	 && test "x$android_enable_checking" = "xyes"; then :  <<<<<<<<<<<<
    ac_enable_checking=yes
  fi

  # There is little point in enabling checking in the build machine if
  # cross-compiling for Android.
  if test -z "$with_android" || test -n "$XCONFIGURE"; then :  <<<<<<<<<<<<

    if test x$ac_enable_checking != x ; then

  $as_echo "#define ENABLE_CHECKING 1" >>confdefs.h

    fi

and I believe that those colons ':' after 'then' are the culprit.  But
my Autoconf-fu is not strong enough to see what has to be done to fix
this.

No, it was because the Android test was incorrect.  Now fixed.

Btw, I don't think I understand the "test -n" part here:

  # There is little point in enabling checking in the build machine if
  # cross-compiling for Android.
  AS_IF([test "$with_android" = no || test -n "$XCONFIGURE"],[
    if test x$ac_enable_checking != x ; then
      AC_DEFINE([ENABLE_CHECKING], [1],
    [Define to 1 if expensive run-time data type and consistency checks are enabled.])
    fi

It sounds like "test -n" there contradicts the comment: AFAIK non-zero
length of $XCONFIGURE means we _are_ cross-compiling, and the comment
says we don't want ENABLE_CHECKING in that case.

Or maybe I don't understand the comment?

Are you sure? Termux and Emacs for Android should be working together
without problem, together with Emacs inside of Termux.

I am a bit confused.. Do you mean that we do not have to reinstall Termux with the Emacs package which, as stated by Po Lu, would request that?

Really I am still using the original Emacs package which does not request to reinstall Termux. Usual I put files in /sdcard/Download and access them from Emacs with C-x C-f /sdcard/Download/foo (maybe also files in /sdcard/emacs_docs should work..)
