em-smart was forcibly re-displaying the screen upwards of 500 times
per screen of output. This caused the Eshell to feel quite slow when
the module was in use. By using fewer hooks and never explicitly
calling 'redisplay' (which was unnecessary) the performance issues go
away (bug#57367).
lisp/eshell/em-smart.el:
(em-smart-unload-hook, eshell-smart-unload-hook): Remove
'eshell-smart-scroll' instead of the now deleted
'eshell-refresh-windows'.
(eshell-smart-displayed, eshell-currently-handling-window)
(eshell-refresh-windows): Delete.
(eshell-smart-scroll-window): Rename to 'eshell-smart-scroll-windows'
and add a bunch of logic originally from 'eshell-refresh-windows'.
(eshell-smart-initialize): Don't add a hook onto
'window-scroll-functions'. Replace 'eshell-refresh-windows' with
'eshell-smart-scroll-windows'.
(eshell-smart-display-setup): Don't refresh windows.
(eshell-smart-redisplay): Rename to 'eshell-smart-scroll'. Delete
'eobp' case.

Move to...
* lisp/eshell/esh-util.el (eshell--region-p)

* lisp/eshell/em-cmpl.el (eshell-complete-parse-arguments): Fix edge
case when 'end' is at beginning of (possibly-narrowed) buffer.
* lisp/eshell/esh-arg.el (eshell-special-ref-alist) New variable...
(eshell-special-ref-default): ... New option...

(eshell-parse-special-reference): ... use them.
(eshell-insert-special-reference): New function.
(eshell-complete-special-reference): Reimplement to use a nested call
to Pcomplete.
(eshell-complete-buffer-ref): New function.

special ref type here.
(eshell-complete-process-ref): New function.
* doc/misc/eshell.texi (Bugs and ideas): Remove now-implemented idea.
* lisp/eshell/esh-proc.el (eshell-process-wait-seconds)
(eshell-process-wait-milliseconds): Make obsolete in favor of...
(eshell-process-wait-time): ... this, and...
(eshell-wait-for-process): ... use it.
* etc/NEWS: Announce this change (bug#66574).
This fixes a small regression from commit eef32d13da.
* lisp/eshell/esh-proc.el (eshell-reset): Declare here.
(eshell-reset-after-proc): Move implementation to...
(eshell--reset-after-signal): ... here...
(eshell-interrupt-process, eshell-kill-process eshell-quit-process)
(eshell-stop-process, eshell-continue-process): ... and call it.
* lisp/eshell/esh-util.el (eshell--unmark-string-as-output): New
function...
* lisp/eshell/esh-mode.el (eshell-mode): ... use it.
* test/lisp/eshell/eshell-tests.el (eshell-test/yank-output): New test
(bug#66469).
This really just generalizes Eshell's previous support for iterative
evaluation of a single current command to a list of multiple commands,
of which at most one can be in the foreground (bug#66066).
* lisp/eshell/esh-cmd.el (eshell-last-async-procs)
(eshell-current-command): Make obsolete in favor of...
(eshell-foreground-command): ... this
(eshell-background-commands): New variable.
(eshell-interactive-process-p): Make obsolete.
(eshell-head-process, eshell-tail-process): Use
'eshell-foreground-command'.
(eshell-cmd-initialize): Initialize new variables.
(eshell-add-command, eshell-remove-command)
(eshell-commands-for-process): New functions.
(eshell-parse-command): Make 'eshell-do-subjob' the outermost call.
(eshell-do-subjob): Call 'eshell-resume-eval' to split this command
off from its parent forms.
(eshell-eval-command): Use 'eshell-add-command'.
(eshell-resume-command): Use 'eshell-commands-for-process'.
(eshell-resume-eval): Take a COMMAND argument. Return
':eshell-background' form for deferred background commands.
(eshell-do-eval): Remove check for 'eshell-current-subjob-p'. This is
handled differently now.
* lisp/eshell/eshell.el (eshell-command): Wait for all processes to
exit when running synchronously.
* lisp/eshell/esh-mode.el (eshell-intercept-commands)
(eshell-watch-for-password-prompt):
* lisp/eshell/em-cmpl.el (eshell-complete-parse-arguments):
* lisp/eshell/em-smart.el (eshell-smart-display-move): Use
'eshell-foreground-command'.
* test/lisp/eshell/esh-cmd-tests.el
(esh-cmd-test/background/simple-command)
(esh-cmd-test/background/subcommand): New tests.
(esh-cmd-test/throw): Use 'eshell-foreground-command'.
* test/lisp/eshell/eshell-tests.el (eshell-test/queue-input): Use
'eshell-foreground-command'.
* test/lisp/eshell/em-script-tests.el
(em-script-test/source-script/background): Make the test script more
complex.
* test/lisp/eshell/eshell-tests.el
(eshell-test/eshell-command/pipeline-wait): New test.
* doc/misc/eshell.texi (Bugs and ideas): Remove implemented feature.
* lisp/eshell/esh-proc.el (eshell-subjob-messages): New variable...
(eshell-record-process-object)
(eshell-remove-process-entry): ... check it.
* lisp/eshell/em-script.el (eshell-source-file): Set
'eshell-subjob-messages' to nil.
* lisp/eshell/esh-cmd.el (eshell-do-subjob): Set
'eshell-subjob-messages' to t.
* test/lisp/eshell/em-script-tests.el
(em-script-test/source-script/background): New test.
In batch mode, SIGPIPEs can cause Emacs to abort (bug#66186).
* lisp/eshell/esh-io.el (eshell-output-object-to-target): Update
comment.
* test/lisp/eshell/esh-proc-tests.el
(esh-proc-test/pipeline-connection-type/middle)
(esh-proc-test/pipeline-connection-type/last): Use '(ignore)', since
that causes no output when called with no arguments, thus avoiding a
risky 'process-send-string'.
This lets us simplify the logic for how we reset
'eshell-current-command' and 'eshell-last-async-procs', as well as
improving correctness of Eshell command forms in a few esoteric
scenarios. Additionally, this helps set the stage for better support
of background commands in Eshell (bug#66164).
* lisp/eshell/esh-cmd.el (eshell-cmd-initialize): Remove addition to
'eshell-post-command-hook'; this is handled in 'eshell-resume-command'
and 'eshell-resume-eval' now.
(eshell-resume-command): Handle resetting the prompt as needed.
(eshell-resume-eval): Use 'unwind-protect' to ensure that we set
'eshell-last-async-procs' and 'eshell-current-comment' at the right
times.
(eshell-parse-command, eshell-trap-errors, eshell-manipulate): Use
'unwind-protect'.
(eshell-do-eval): Allow 'eshell-defer' to pass through
'unwind-protect' forms without actually calling the unwinding forms
(yet).
* lisp/eshell/esh-proc.el (eshell-kill-process-function)
(eshell-reset-after-proc): Make obsolete. The behavior is now handled
in 'eshell-resume-command'.
(eshell-gather-process-output, eshell-sentinel)
(eshell-interrupt-process, eshell-kill-process, eshell-quit-process)
(eshell-stop-process, eshell-continue-process): Run 'eshell-kill-hook'
directly.
* test/lisp/eshell/esh-cmd-tests.el (esh-cmd-test/throw): New test.
When checking if the other processes in our pipeline are "alive", we
also need to check whether their sentinels are finished. Otherwise,
we might proceed with command evaluation while one of the other
processes is still cleaning up.
* lisp/eshell/esh-proc.el (eshell-process-active-p): New function...
(eshell-wait-for-process)
* lisp/eshell/esh-cmd.el (eshell-resume-command): ... use it.
* lisp/eshell/esh-cmd.el (eshell--region-p): New function.
(eshell-with-temp-command, eshell-parse-command): Support
'(:file . FILENAME)' to use the contents of FILENAME.
* lisp/eshell/em-script.el (eshell-source-file): Call
'eshell-parse-command' and use backticks.
This regressed (I believe) due to 2ec41c174f.
* lisp/eshell/esh-cmd.el (eshell-resume-eval): Check for non-nil
'retval' instead of for a process list (nil is also a technically a
process list!).
* test/lisp/eshell/eshell-tests.el
(eshell-test/eshell-command/background-pipeline): Remove unnecessary
'copy-tree'.
(eshell-test/eshell-command/output-buffer/sync)
(eshell-test/eshell-command/output-buffer/async): New tests.
Now, 'eshell-debug-command' works more like 'format-message', which is
how we usually use it.
* lisp/eshell/esh-util.el (eshell-always-debug-command): New function.
(eshell-debug-command): Simplify. Update callers.
This should fix bug#59103, bug#65590, and bug#65601.
* lisp/eshell/esh-proc.el (eshell-sentinel): Set ':eshell-handles' to
nil when finished with I/O.
(eshell-wait-for-process): Wait until ':eshell-handles' is nil.
This will hopefully help resolve some timing issues with subprocesses
in Eshell. There's now much less chance of output going missing when
using redirects.
* lisp/eshell/esh-proc.el (eshell-gather-process-output): Set
':eshell-stderr-live'...
(eshell-sentinel): ... use it.
* lisp/eshell/esh-proc.el (eshell-sentinel): Only output abnormal
status when stderr is interactive.
* test/lisp/eshell/esh-proc-tests.el
(esh-proc-test/kill-process/redirect-message): New test.
This doesn't change anything right now, but it will prevent future
issues when we add the ability to resume suspended processes in
Eshell.
* lisp/eshell/esh-proc.el (eshell-sentinel): Check for "run" status
earlier.
Previously, we only waited until the tail process was finished, but
now, we wait for all of them. This is more consistent with other
shells, and prevents some cases of a process's output coming *after*
we continued past its pipeline.
* lisp/eshell/esh-cmd.el (eshell-resume-command): Simplify
conditionals, and check that all the foreground processes are dead
before resuming Eshell command.
* test/lisp/eshell/esh-cmd-tests.el
(esh-cmd-test/pipeline-wait/multi-proc): New test.
This has the extra benefit that Eshell now only considers a pipeline
to be done when *all* of its processes are done (previously, it
checked only the last one in the pipeline).
* lisp/eshell/esh-util.el (eshell-process-pair-p)
(eshell-make-process-pair): Rename to...
(eshell-process-list-p, eshell-make-process-list): ... these, and
handle lists of processes. Update callers.
* lisp/eshell/esh-cmd.el (eshell-head-process): Use 'car'.
(eshell-tail-process): Get the last element of the list.
(eshell-do-pipelines): Return a list of all processes in the pipeline.
(eshell-do-pipelines-synchronously): Return the result of the first
command (usually t or nil).
(eshell-execute-pipeline): Simplify.
(eshell-do-eval): Pass all processes to 'eshell/wait'.
This ensures that we supply Tramp with the local PATH so that it can
do its job of starting the local "ssh", or whatever the method uses
(bug#65551).
* lisp/eshell/esh-proc.el (eshell-gather-process-output): Add special
handling for remote processes.
* test/lisp/eshell/esh-proc-tests.el
(esh-var-test/remote/remote-path): New test.
By treating 'eshell-current-modifiers' as a hook, we can simplify much
of the code working with it and ensure that we call modifiers in a
more-correct order.
* lisp/eshell/em-dirs.el (eshell-expand-user-reference-1)
(eshell-expand-user-reference): Simplify. We now only get a single
argument.
(eshell-parse-user-reference):
* lisp/eshell/em-glob.el (eshell-add-glob-modifier):
* lisp/eshell/em-pred.el (eshell-parse-arg-modifier): Use 'add-hook'.
This lets us finally obsolete 'eshell-prompt-regexp', making it
simpler for users to customize their prompts.
* lisp/eshell/em-prompt.el (eshell-prompt-function): Update docstring.
(eshell-prompt-regexp): Make obsolete.
(eshell-prompt-initialize): Remove 'eshell-prompt-regexp' code.
(eshell-prompt-mode-map): Remap paragraph navigation commands to...
(eshell-forward-paragraph, eshell-backward-paragraph): ... these new
commands.
* lisp/eshell/em-prompt.el (eshell-next-prompt): Make N optional.
When navigating, first move to the end of the prompt. This makes the
subsequent navigation more predictable.
(eshell-previous-prompt): Mane N optional.
* test/lisp/eshell/em-prompt-tests.el
(em-prompt-test--with-multiline): Move to "Code" section.
(em-prompt-test/next-previous-prompt-with): Rename to...
(em-prompt-test/next-previous-prompt-1): ... this, and add additional
test cases. Update callers.
(em-prompt-test/forward-backward-matching-input-with): Rename to...
(em-prompt-test/forward-backward-matching-input-1): ... this, and
improve existing test cases.

Previously, these were enabled/disabled at byte-compilation time, but
we want to control them at runtime.
* lisp/eshell/esh-cmd.el (eshell-eval-command): Call

(pcomplete/eshell-mode/eshell-debug): Move from "esh-cmd.el" and
reimplement.
* lisp/eshell/eshell.el (eshell-command): Pass the original input to
'eshell-eval-command'.
* doc/misc/eshell.texi (Built-ins): Update documentation for
'eshell-debug'.
Previously, in a remote directory, '(eshell-get-path)' would return a
list of strings like "/ssh:localhost://usr/bin". While that shouldn't
break most things, it's not strictly correct either. See bug#65551.
* lisp/eshell/esh-util.el (eshell-get-path): Use 'concat' instead of
'file-name-concat'.
* test/lisp/eshell/esh-util-tests.el: Require 'tramp' and
'eshell-tests-helpers'.
(esh-util-test/path/get, eshell-util-test/path/get-remote): New tests.
If a process is busy writing output when 'eshell-sentinel' is called,
it might take a bit of time to finish up. Don't call
'eshell-kill-process-function' until we're really finished
(bug#59103).
* lisp/eshell/esh-proc.el (eshell-sentinel): Call
'eshell-kill-process-function' in 'finish-io'.
This should be functionally the same as the previous implementation in
most cases (which consulted its membership in 'eshell-process-list'),
but is more flexible. It's now possible to wait for processes that
aren't in 'eshell-process-list'.
Additionally, use 'process-live-p' instead of examining
'process-status' in a few places. This is simpler, and a bit more
correct too for certain types of processes (though it likely doesn't
matter in practice).
* lisp/eshell/esh-io.el (eshell-close-target)
(eshell-output-object-to-target)
* lisp/eshell/esh-proc.el (eshell-process-interact): Use
'process-live-p'.
(eshell-wait-for-process): Use 'process-live-p' and remove reference
to 'eshell-process-list'.
* lisp/eshell/em-hist.el (eshell-add-input-to-history): Refactor to
use 'pcase' and correct the logic for the 'erase' case.
* test/lisp/eshell/em-hist-tests.el: Require our test helpers.
(eshell-write-readonly-history): Rename to...
(em-hist-test/write-readonly-history): ... this.
(em-hist-test/add-to-history/allow-dups)
(em-hist-test/add-to-history/no-consecutive-dups)
(em-hist-test/add-to-history/erase-dups): New tests (bug#63360).
* lisp/eshell/esh-var.el (eshell-variable-aliases-list): Add "PAGER".
(eshell-var-initialize): Make 'comint-pager' buffer-local and bind it
in subcommands so that we can temporarily set it as necessary.
* test/lisp/eshell/esh-var-tests.el (esh-var-test/pager-var/default)
(esh-var-test/pager-var/set, esh-var-test/pager-var/unset)
