CEDET merge

CEDET merge

[Chong Yidong]

I have merged most of the CEDET branch into the trunk.  You may need to
bootstrap; please let me know if there are any build failures.

I have done what I can to clean up CEDET to conform to Emacs standards;
if you see anything I missed, please go ahead and make the change.

Currently, the interface to Semantic is via "M-x semantic-mode", and to
EDE via "M-x global-ede-mode"; these should install a "Development" menu
on the menu bar that can be used to enable further features.
Suggestions about improving this interface, and the CEDET integration in
general, are welcome.

(If you want to make bigger changes to the internals of CEDET itself,
please discuss first, because we need to coordinate that kind of change
with upstream.)

I've tried to byte-compile some packages like company-mode [1] and
JDE [2] with the CEDET included in Emacs, and they fail because some
files that they require have a different name now. For example:

   In toplevel form:
   company-semantic.el:21:1:Error: Cannot open load file: semantic-ia

Was this renaming of files really necessary? It breaks backwards
compatibility and imposes additional work on package authors and
distros.

Thanks.  I suggest to update ldefs-boot.el.

No one suggested any other solution to the filename problem.

Maybe we could get around this by adding a `cedet-compat' package that
loads everything everything in CEDET and provides all the old CEDET
feature names; then loading this file will provide everything a
third-party package needs to compile.

I see warnings about shadowing libraries, after bootstrapping:

  This site has duplicate Lisp libraries with the same name.
  If a locally-installed Lisp library overrides a library in the Emacs release,
  that can cause trouble, and you should probably remove the locally-installed

Thanks. I am working on Rudel, a library that requires CEDET, and this
should make the install process much easier.

Rudel uses eieio as well as inversion.el, fame.el, and working.el. The
last three of these are files from CEDET's common/ directory. From what
I can tell, fame.el and working.el were not included in the merge. Was
this intentional? What were the deciding factors in what to include?

Perhaps they could be offered using package.el if we decide to integrate
it into Emacs?

That's strange.  Does your load path include lisp/cedet/semantic after
bootstrapping, and if so is there a subdirs.el in lisp/cedet for some
reason?  It should not be there; I made a change in Makefile.in
specifically to prevent subdirs.el from being created in that directory.

The obvious solution is not to support CEDET on platforms with 8+3
filenames ...

Not sure if loading everything at once is a good idea. CEDET is huge.
But couldn't at least the old feature names be provided by the single
files? (As it was done for newsticker-*, for example.)

Yes, it includes cedet, cedet/semantic, cedet/semantic/wisent,
cedet/semantic/symref, cedet/semantic/decorate, cedet/semantic/bovine,
and cedet/semantic/analyze

> and if so is there a subdirs.el in lisp/cedet for some

Yes, there is.  It says this:

    (normal-top-level-add-to-load-path '("semantic" ))

There's also subdirs.el in cedet/semantic.

What change you made, and in what Makefile.in?

All I can say is that I ran `confugure' and `make -j6 bootstrap'.  And
I have the Bash history to prove that.

[Time passes...]  Ah, I think I see the problem: this subdirs.el is
very old, from 2 weeks ago.  I think it was created when you added the
directories in the CEDET branch, at which time they appeared (as
empty) on HEAD as well, and then make-subdirs created the file.  If I
delete that file, the problem is gone.

So maybe "make bootstrap" should delete all subdirs.el, as cleanup.

I'm no expert, but according to Eli, having files longer than 8+3 in the
tarball leads to problems unpacking the tarball on DOS, and other
problems on some versions of Windows:

We can do that, but how does this solve the problem?  The old `require'
calls still won't find the correct file (unless we implement feature
aliases or something like that).

Supporting such antediluvian platforms is nice as long as it's
possible without too much effort. But if it becomes too much of a
burden one should reconsider if it's worthwhile (IMHO).

The renaming also increases the differences between Emacs and XEmacs
and packages intended for both will have to add further case
distinctions.

It wouldn't solve it completely, but once the file is loaded the
feature (with the right name) will be present, and the third-party
package will run.

antediluvian. Windows. Well, maybe, but on which of the platforms on
which Emacs runs does it have the most users? Come the revolution, we
FOSSers can drop compatibility hacks but until then, comrades, I'm
afraid we'll have to keep making allowances for those still in chains.

Without the bootstrap, it failed to compile the cedet sources.  With a
make bootstrap, it just worked, out of the box.  :-)

Quick question.  Are there any CEDET manuals in this build?  I didn't
see any.

They need to go in doc/misc, but I haven't done that yet.  (They
probably need to be checked too.)

I'll do this over the next few days, unless someone would like to do it
for me (they can be found in the CEDET upstream repository).

I didn't include working.el (and fame.el, which is only there for
working.el) because I couldn't work out what advantage it brought over
the built-in progress reporter, which is a couple of hundred lines in
subr.el, already documented in the manual, and works fine.  This seems
too big a solution for a problem that's tangentially related to the rest
of CEDET, but maybe you can convince me otherwise.

As for the other omitted stuff, there are a couple of files in Semantic
not written by Eric that we don't have paperwork for yet (the Imenu
support and the Erlang and Python parsers).  Also the Srecode template
files and Semantic grammar files, which I haven't figured out where to
put (maybe a subdirectory in admin; any help with this task would be
appreciated).  And I may have overlooked some other things.

As far as I understand it, the 8+3 limitation is only relevant for
MS-DOS and very old (pre-NT?) MS-Windows versions. So users of recent
Windows should not be affected by it.

It seems you did not merge semantic/adebug.el, was this deliberate?

semantic/db-find.el claims that data-debug-insert-tag-list is defined
in data-debug.el, but it is not, it is defined in adebug.el, which is
not present in the trunk.

Your email has reminded me that I've wanted to rename semantic-adebug.el
to something more descriptive.  It was originally a semantic specific
tool which I generalized as a data-debug.el for most things in Emacs.

Not that I have a fabulous name in mind though.  "a" was just a vowel to
go along with "e" debug which is a bit lame.  It should probably be
semantic-datadebug.el to match up with eieio-datadebug.el.  (Using the
parlance of the CEDET suite on sourceforge.  For Emacs I guess it would
be semantic/datadebug.el.)

semantic/cedet/wisent/javat-wy.el has coding issues, because of this line:

     ("char" summary "Integral primitive type ('^@' to '\357\227\227')
(0 to 65535)")

so on Windows it is decoded as "=(Unix)" (i.e., no-conversion, LF),

Thanks a lot I'm very curious about this new features.

Giving the ede part a quick try[0] I stumbled upon a bunch of problems:

- After enabling global-ede-mode mode first observation was, that the
  new Development-menu was not accessible when using the pseudo menu on
  an tty (haven't tested an graphical interface yet): <F10> shows
  `---Development' among the menu items, which cant be selected.

- After creating a new project of the type `automake' (ede-new) and
  adding a new target with one source file (plain hello world in c) I
  tried `ede-compile-target' which reviled an error in one provide form.
  This patch fixes it:

     ))
 
-(provide 'ede-srecode)

 ;;; ede-srecode.el ends here

- But after that fix compiling still fails.  Now with:

Any ideas?

The reason Rudel uses the CEDET one vs the built-in Emacs one is that it
needs a way to indicate that something is happening without knowing the
overall percentage of the task that is actually complete. I believe this
is commonly known as "pulsing" or a "spinner".

We could probably implement this as an addition to the built-in progress
reporter in subr.el; would this be a welcome feature?

The same happens on Unix, because the null byte forces the file to be
treated as binary.

Why, because the lines actually have CRLF Windows-style EOLs on your
machine?  Or for some other reason?  IOW, I don't see why
no-conversion should cause the file not to compile, and only on
Windows.  What am I missing?

Anyway, 2 ideas to work around this:

  . Replace the null byte with \000

  . Put "inhibit-null-byte-detection: t" in file-local variables.

Checking it out with CVS, yes, it has CRLF EOLs. In fact, editing it
all lines end with ^M.

Here's what I've come up with:

(defvar progress-pulse-values ["-" "\\" "|" "/"]
  "A vector of characters to use for pulsing progress reporters.")

(defun make-pulsing-progress-reporter (&optional message)
  "Return a pulsing progress reporter that display MESSAGE.
MESSAGE can contain all formatting characters accepted by
`format'. If message is nil, the string \"Working ...\" is
displayed.

Example:
(let ((rep (make-pulsing-progress-reporter \"Connecting\")))
  (dotimes (n 3)
    (sleep-for 0.1)
    (progress-reporter-pulse rep \"Connecting [new]\"))
  (dotimes (n 3)
    (sleep-for 0.1)
    (progress-reporter-pulse rep \"Connecting [synching]\"))
  (dotimes (n 3)
    (sleep-for 0.1)
    (progress-reporter-pulse rep \"Connecting [idle]\"))
  (progress-reporter-pulse rep \"Connecting \")
  (progress-reporter-done rep))"
  (cons nil ; total value is not known
    (vector nil 0 'dummy (or message "Working ... "))))

(defun progress-reporter-pulse (reporter &optional new-message)
  "Advance pulsing indicator of REPORTER. Display NEW-MESSAGE if given."
  (let* ((parameters (cdr reporter))
         (message    (or new-message (aref parameters 3)))
         (index      (aref parameters 1))
         (new-index  (mod (+ index 1) 4)))
    (aset parameters 1 new-index)
    (aset parameters 3 message)
    (let ((message-log-max nil)) ; No logging
      (message "%s %s"
               (aref progress-pulse-values new-index)
               message))))

The example in the docstring should make it clear how this works. It's
fairly close to how the existing progress reporter works, but it's got

I have my paperwork in. I could submit this as a patch if that's more

I think `make-progress-reporter' should do "pulsing" automatically if
min-value and max-value are null, instead of providing a new function.

"M-x semantic-mode" works, but if I do "M-x global-ede-mode", I get the
following error:

   Cannot open load file: ede/makefile-edit

If there are already source-file buffers when I do M-x global-ede-mode,
then I the error immediately, otherwise, it happens when I visit a
source file or directory.

I tried "make bootstrap" etc, with no improvement.

I get the following error with semantic-mode:

   (a) visit the following source file:

---- cut here ----
#include <stdio.h>

int main ()
{
  printf ("hello world\n");
  return 0;
}

   (b) do M-x semantic-mode

   (c) position point after "printf"

   (d) use the command: "C-c , j"
       (I don't even know what that command does, but it gets an error...)

The attached patch implements this. So make-progress-reporter will make
a pulsing reporter when min-value and max-value are not specified.

I made it so that you must use progress-reporter-pulse to update a
pulsing reporter, but I realized afterwards that it would be easy enough
to have progress-reporter-update check to see if the reporter is a
pulsing one or not and call the correct function underneath without the
caller having to think about it.

If you think this is a good idea I can make the change.

This problem is still there.  A question to all CEDET/EDE experts: is
this an bug or am I missing something?

I haven't had the opportunity to use the Emacs/CEDET merged version, but
I can provide some help here.  The Semantic configuration was setup to
be done in a .emacs file, or very early on, and all the necessary setup
is done in mode hooks after that.  If you load in a C file, then turn on
Semantic, then your current buffer will not have the right variables
setup.  In this case, it is a variable that tweaks the syntax table.

I think the right order would be

M-x semantic-mode

;; create the file

continue with above script.

I would guess that the new semantic-mode should either warn on
pre-existing buffers, or find a way to apply itself to pre-existing
buffers.  The standalone CEDET install works around this by the file
that loads CEDET doing these installs in your .emacs file.  The
assumption being that if you installed CEDET, you want this stuff on,
which is not the case for Emacs.

Chong Yidong said he hadn't figured out where to put the SRecode
templates.  Since EDE uses Srecode to templates to create Makefiles,
that is likely the problem.  The way SRecode looks up template files may
also not be compatible with where the templates will eventually live in
Emacs, so that would need to be updated.

Short term, you could get the templates from CEDET CVS in
cedet/srecode/templates and cedet/ede/templates and place them in
equivalent locations just under srecode.el and ede.el to get past this
until there is a home for SRecode Templates in Emacs.

hmm, didn't work -- or maybe I haven't fully understood what to do.
Here is what I tried:
- I checked out the current cedet head from CVS
- I copied the directory cedet/ede/templates to
  /usr/share/emacs/23.1.50/lisp/cedet/ede/templates and
  cedet/srecode/templates to
  /usr/share/emacs/23.1.50/lisp/cedet/srecode/templates

That didn't work, so I tried puting all *.srt files from
cedet/ede/templates directly under
/usr/share/emacs/23.1.50/lisp/cedet/ede/ (and same for
/usr/share/emacs/23.1.50/lisp/cedet/srecode/) but this didn't work
either....

What am I missing?

I've attached the patches that implement this. Pulsing reporters can use
progress-reporter-update like normal ones and can have their messages
changed using progress-reporter-force-update.

I must apologize for not actually trying out the Emacs integration.  It
is pumpkin throwing season which keeps me busy.  (see
www.punkinchunkin.com for the sport, or www.siege-engine.com for my
team.)

Anyway, the template directory is set up like this for EDE:

  (let* ((lib (locate-library "ede.el" t))
	 (ededir (file-name-directory lib))
	 (tmpdir (file-name-as-directory
		  (expand-file-name "templates" ededir))))
    (when (not tmpdir)
      (error "Unable to location EDE Templates directory"))

    (require 'srecode-map)
    (add-to-list 'srecode-map-load-path tmpdir)
    (srecode-map-update-map t)


but you could just do this in your basic setup by specifying a load path
for srecode directly, as in the code above reveals.

I've added the SRecode templates to etc/srecode.

Building in EDE should now work---provided Semantic is enabled from the
start.  We still need to provide a way for SRecode to call Semantic to
parse the template buffer, when Semantic is not currently enabled (this
functionality will be useful for other parts of Emacs too).

Semantic can parse files even if all the other related utilities are
never enabled.  As long as srecode-template-mode sets up the parser info
itself, and not in the new "semantic-mode", then it can use the Semantic
API to parse buffers during template compilation without interfering
with someones desire to not enable Semantic parsing and utilities in
other files, like C++ mode.

Thanks for your reply.  I have to admit, that I hardly read any more

This (and some digging in the content of srecode-map-load-path) brought
me a step further.  I copied all ede and srecode templates from the
cedet CVS to ~/.srecode/ which was in my srecode-map-load-path.

Now I get an different error on any attempt to rebuild a projects
makefile (which afaiu is also a part of compiling).  From *Messages*:

Is more information needed than that provided during ede-new and

How about this:

In the Emacs-integrated version of Semantic, we semantic-new-buffer-fcn
so that it runs the mode-dependent parser setup functions before doing
anything else.  This is as opposed to running the parser setup functions
from the mode-hooks, as your upstream code does, or in the body of
semantic-mode, as the Emacs version currently does.  So, when srecode
calls semantic-new-buffer-fcn, the right setup will take place.

What do you think?

I think I have failed to understand the above.

Does the Emacs integrated CEDET no longer use mode-local to call
semantic-new-buffer-fcn?  That could be good news.  The hooks available
in Emacs to detect a change in major mode for mode-local.el have been
challenging to get right, and I think they can still sometimes not work
right.

I did fail to explain in my paragraph above that mode-local.el would
need to be active for any files to be parse-able.  I was referring to
semanticdb, and semantic-idle features do not need to be enabled for
SRecode to be able to parse/compile template files.  As you point out,
the semantic-new-buffer-fcn does need to run, and the mode-local
settings need to be active for semantic to parse stuff.

Is there a desire to have srecode parse/compile template files while
leaving mode-local inactive?  Does mode-local get activated with
semantic-mode?  Perhaps I should check out a fresh copy of 
Emacs to better understand.  I've been worried of doing so because I
know I'll then need to also figure out how to enable my CEDET distro
shadowing the Emacs version, and I don't really want to do that work.

No, semantic-new-buffer-fcn is still called from mode-local.  I was
proposing to move the parser setup functions from the mode hooks into
semantic-new-buffer-fcn.  That way, we can parse an existing buffer
(e.g., a buffer that already exists by the time Semantic is enabled, or
a buffer that Srecode wants to parse without enabling Semantic
globally), simply by calling semantic-new-buffer-fcn.

With the latest changes to the CEDET integration this problem vanished,
too.  Now Makefile generation by EDE basically works.

However I still witness a bunch problems with my simple test cases.

Is it useful to report them here or should I wait for the CEDET
integration process to become more complete?

The doc header at the top of pulse.el mentions the function

While the feature specified which allows fcns such as goto-line to do a
pulse after the line has been gone to is certainly superfluous (I don't
use them), what would be he recommended way to make it possible to make
such changes w/out using advice?

I recognize that `beginning-of-defun' and friends discussed earlier
would be the model, but I can't imagine adding such replacement features
into every user facing command just in case.

For the pulse case, is there an interest in snazzing up the original
function list with pulsing, or is it too gratuitous to even contemplate?

I've checked the new code base with our test suite and fixed a bunch of
stuff. Everything's working now except for a few minor things, so I
think the branch is now ready for merging.

You can obtain a patch file from our 'to-emacs' branch (for details see
my last mail), but I've also attached it to this message so everyone can
check it easily. There's no ChangeLog yet, so if you want to check the
logs you still need our 'to-emacs' branch.

Please take a look at the issues I raised in my previous mail, since
they still apply (esp. regarding checking for papers).

Additionally, I've also regenerated the Elisp parsers from the updated
grammar files. This converted some more explicit copyright ranges like

Copyright (C) 2002-2004, 2007, 2010-2012  Free Software Foundation, Inc

to a simple range like this

Copyright (C) 2002-2012 Free Software Foundation, Inc.

Is this acceptable? Also, it removed the 'Author: David Ponce' line from
cedet/semantic/grammar.el, but I think it didn't make sense anyway since
it is a generated file (from admin/grammars/grammar.wy, where he's still
credited).

I left the grammars and parser generator in admin/grammars for now, but
IMO the generator bovine-grammar.el and wisent-grammar.el should
eventually be moved to their proper locations underneath lisp/. The main
grammar generation is already in lisp/semantic/grammar.el and hence was
in Emacs all the time; the two files above are just refinements for the
two different grammar styles.

This should read: cedet/semantic/grammar-wy.el.

Also, I should mention that this patch introduces two new files:
etc/srecode/c.srt and etc/srecode/ede-autoconf.srt, which will have to

If the former is the true statement, that the latter is not an

If we're talking about Emacs, "2002-2012" is a
true statement, is acceptable, and is what the
GNU coding standards currently recommend.
New versions of Emacs were published (at least via
a revision-control system) in all those years, and
there's a "NOTE ON COPYRIGHT YEARS" in the README
file that explains all this, so the GNU rules are being
followed for copyright years if the file says just
"2002-2012".

CEDET was not part of Emacs until 2009, so it depends on when/how CEDET
was released before that.

Unfortunately, I see now that I forgot to remove some defadvices. After
applying the patch, please remove the two defadvices for hideif from
semantic/bovine/c.el. We have to see if we somehow can implement this
feature using hooks, or maybe we have to remove the semantical
hideif-feature altogether.

Also, I merged lots of stuff from senator.el (including some defadvices)
which shouldn't land in Emacs. So for now, I would suggest to simply
revert senator.el after the patch is applied. I think Eric wanted to
remove senator.el at some point in time, but I guess we don't have a
good replacement yet...?

I've done the merge, omitting senator and the defadvices as you
suggested.

To replace the defadvice, it is acceptable to just change the code of
hif-defined and hif-lookup directly to refer to
semantic-c-takeover-hideif (if it is bound); no need to use a hook.
Feel free to submit a patch, or I'll get around to it when I have the
time.

Attached is a patch of leftovers, consisting of a few whitespace
cleanups and file header fixes.  Please apply to the to-emacs branch or
wherever is appropriate.  Thanks.

Was removing the "Package-Version" header from eieio.el intentional?
It broke some ELPA packages.

Thanks for pointing this out.  I restored the headers.

David, could you restore the Version: headers upstream as well?  (These
headers are needed by ELPA packages which depend on CEDET components;
the ELPA system generates package versions from them.)  Patch attached.

Will do. I didn't know that ELPA depended on them; I thought they were

wisent-grammar.el would be renamed to lisp/cedet/semantic/wisent/grammar.el

bovine-grammar.el to lisp/cedet/semantic/bovine/grammar.el

I guess the functions `wisent-make-parsers' and `bovine-make-parsers'
and the variables they need could be put in a new file which stays in
admin/grammars, since you've added them specifically for the parser
generation in Emacs trunk.

I guess all that's left then is to add proper provide statements and
autoload cookies to the two above files (for the derived major modes and
for the additions to auto-mode-alist).

I think we can leave them in those files for now, until we fix the build
system to generate the parsers during the Emacs build process.

By the way, could you or Eric kindly write up a NEWS entry briefly
describing the major changes to CEDET since CEDET-1.0 / Emacs-24.2?

I'm also interested to hear about how close we are to having Emacs's
CEDET and the upstream CEDET actually in sync (and kept in sync via
a semi-automatic process).

Regarding the files which are both in Emacs and in CEDET: those are
pretty much in sync now except for some compatibility code we have to
keep for Emacs 23.1.. We also have some 'defadvice' hacks which we
obviously cannot merge. For getting rid of the defadvices, some changes
in Emacs core packages are needed, but I didn't have time to do that
before the freeze (for example, getting proper help buffers for EIEIO
classes and methods is pretty high on my TODO list).

There are still some packages which are only in CEDET upstream for
several reasons: They're either pretty new and not well tested, or are
in our 'contrib' directory and don't have proper papers, or because they
are a bit obscure (sorry Eric ;-) ) and well separated and hence would
better fit into ELPA. For example, I think Cogre (for generating UML
graphs) would be a good candidate for an ELPA package.

Also, we now have two additional branches in CEDET for doing merges to
and from Emacs; those are in fact "real" branches, meaning they have a
common history, and after the first batch of humongous merges they work
pretty painless now. The real work is in doing the 'diff|patch' thingy
from Emacs to CEDET, but I've written a package for that which makes
that fairly fast. All this should make it possible for me to do regular
merges from now on, like the Gnus/Org people do.

In addition, we are planning to move development of certain packages
completely to Emacs trunk. We already did that for Speedbar; the next
candidates are EIEIO and mode-local.

OK.  I expect the removal of defadvice will require some changes to the
core, so probably some discussions to agree on how to do it, right?

Adding those that can (i.e. that have the needed copyright paperwork) to
GNU ELPA would be great, yes.

Sounds good, thank you very much for that work.

Reminds me: we should start labeling the files not just with "who's the
maintainer" but also with "is there some external upstream".  Maybe by
adding a "Canonical-URL:" header for those externally-maintained files?

While we generally expect upstreams to take care of tracking the changes
we install, there are many cases where changes only make sense if
there's no external upstream.  E.g. switching from `cl' to `cl-lib',
where the upstream will probably not want to integrate this change
because they care about backward compatibility.

I have some approximate memory of which packages are externally
maintained and which don't, but it would help if I didn't have to rely
on that fuzzy memory.

I don't know why those manuals were not included during the first

Sure. I have some ideas on how to do the help buffer stuff for EIEIO,
but it doesn't make sense to discuss this during the freeze.

Cogre was written by Eric, but maybe others have contributed. We will
have to look that up.

I think a simple flag would suffice, so that those files are excluded
from large changes which break compatibility to older versions, like the
move to `cl-lib'.

Thanks. I forgot one thing: For generating a parser, Semantic must be
enabled. That means, if a user just loads a grammar and hits C-c C-c
without Semantic being enabled, he'll get a "bad input grammar"
error. We have actually the same problem with Srecode templates (see Bug
#9968).

I think it is clearly not a good idea to simply enable Semantic globally
in this case. Instead, we could enable it only for the current buffer by
putting

  (unless semantic-mode
    (require 'semantic)
    (semantic-new-buffer-fcn))

into bovine/wisent-grammar-mode and srecode-template-mode. I think this
should always work. Eric, please correct me if I'm wrong.

extract the relevant portions from there.

To revive this thread: I think the following manuals are currently
missing from Emacs:

- Srecode, as mentioned by Glen above
- Bovine and Wisent, which are now proper Emacs packages and hence their
  manuals should be present.

I've skimmed the logs and the Srecode docs were pretty much completely
written by Eric. Wisent and Bovine were written by David Ponce and
Eric. Also, Richard Y. Kim is credited in the AUTHOR line.

Thanks for following up. If everyone who wrote non-trivial portions of
these manuals has a copyright assignment, then I can't see any reason
not to include them in Emacs. For Richard Kim, it looks like anything
before 2010-1-8 is definitely fine.

Is it possible to update Java parts of CEDET in Emacs with the

CEDET Merge

[Edward John Steere]

Hello Everyone,

I've been working on a branch in upstream CEDET which brings it up to
date with the changes which have been made in Emacs core.  I started
this work with the intention of simplifying the merge process from CEDET
upstream into core so that users can benefit from improvements to CEDET
more easily.  I found that the divergence between the two versions of
CEDET has grown quite a bit and all of my work has been dedicated to
getting it to run on Emacs master (26?).

My branch now passes all of CEDETs tests when built against Emacs
@512e988.  I'd like to get these changes synchronised with Emacs core
and have my branch merged to upstream (i.e. CEDET on source forge).

This could be the first step with the second being a repackaging of
upstream so that it only contains the parts which are under active
development and can be installed via ELPA.

May I contribute my changes to a branch on the Savannah repository for
review/commentary?  (If yes, then It'll take a little bit of time to
merge the changes in my branch of CEDET back into Emacs core before I
actually push them up.)

Kind regards,

Edward Steere

It's great to hear that you have been working on this. I'm also very
interested in getting CEDET upstream and CEDET in emacs synchronized
again. Please see also this bug report:

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=23792

This also contains a patch for the emacs sources which I've come up
with half a year ago, but it's probably incomplete and even wrong in
places. But maybe we can compare what we did.

Do you have a git repository cloned from CEDET upstream which contains
your work somewhere? Or did you start by modifying the built-in CEDET
in emacs?

I remember seeing your post a while ago, but had forgotten about it.
I'll take a look now.

I tried various approaches (with varying degrees of success) before
going for something rather brute force: I diffed every file in CEDET
from Emacs core to it's corresponding file in upstream (creating a diff
file per file-pair) and applied the changes to upstream by hand.

At the moment my changes are living on a private repository.  I'd like
to do some tidying up with regards to commits before I make them
available.  I'll get to work on that tomorrow.

Hi All,

Please may I have some advice.  I've been trying to get my change merged
into Emacs core locally, and have had little (read no) success.  These
are the approaches I've tried so far (not verbatim):

 1. git remote add ~/wip/cedet cedet && git merge
 --allow-unrelated-histories etc.
 2. git subtree (not the right model because Cedet mirrors the layout of
    sources in Emacs core)
 3. rm -rf ~/wip/emacs/lisp/cedet && cp ~/wip/cedet/lisp/cedet ~/wip/emacs/cedet

I've opted for option 3 because I realised that I'd already done the
merge in the other direction and now the state of that branch should be
exactly reflected in core.  However, when I try to bootstrap Emacs I get
errors when loading loaddefs.el in lisp/.  It complains about
eieio-defclass-autoload being undefined -- which is fair enough because
that's only autoloaded later, removing the class autoloads which caused
the autoloads to be added produces the same error for
ede-project-autoload.  In the interests of seeing how far I could go
before completely bombing out I removed this autoload as well and I was
confronted with another autoload error, this time in the `jka'
compression library (!?)

What follows is the error with a few lines before it for context (you
can substitute the void variable error with a similar function is void
error for an idea of how the previous two errors looked):

make[3]: Leaving directory '/home/edward/emacs/leim'

Did you try deleting loaddefs.el and running "make maintainer-clean"
before bootstrap?

If you did, and the problem persists, please show the offending parts
on loaddefs.el which trigger these errors.

Re: CEDET Merge

[Edward John Steere]

Hi Eli,

I did, but to be sure I just did a fresh copy across and ran:
"make maintainer-clean && make bootstrap" and it failed again with the
same error.

Here are the offenders for the first error (they come from a new module
in Cedet called cogre):

;;;### (autoloads nil "cogre" "cedet/cogre.el" (0 0 0 0))
;;; Generated autoloads from cedet/cogre.el

Search for that variable in all of the lisp directory and its
subdirectories.  What hits do you see?  Are any of them in cedet
directories?

Nope only hits when I grep recursively from lisp/ are in:

 - subr
 - jka-compr

Sure.

The plan is to start by getting the whole of Cedet compiling and
starting up in core and then taking a more deliberate approach to what
stays and goes.  I'm taking this approach because the alternatives
require a bit more historic knowledge of Cedet than I have.

Are you aware of a better approach?

The problem with this approach is that you loose lots of history for the
changes that are applied. In Emacs this is especially problematic
because of the copyright issues. So one will need at least a proper
ChangeLog, saying which authors changed which functions, but the Emacs
maintainers will have to say if that would suffice of if we need
authorship information for each line that is applied.

So the "Right Way" would be to apply the upstream commits that happened
since the last CEDET merge to the Emacs repo. I had a package for doing
that, but it was based on Bazaar, so that went they way of the
Dodo. It's called cedet-emacs-merge.el and is in the CEDET repo. I don't
think it makes sense to port it to git, because we actually agreed some
time ago to drop the CEDET repo altogether, so we would "only" need one
final one-way merge. It's been on my TODO list for ages, and I'm really
sorry that it still has not happened yet.

In my opinion, the first thing that should be done is to port the test
suite to Emacs, meaning the unit and integration tests for Semantic and
EDE, ripping out all tests for stuff that is not in Emacs. I already did
that for EIEIO, but for Semantic and EDE a lot is missing. It will make
it much easier to find regressions while doing the merge.

Alright.  It shouldn't be too difficult to merge with the commit history intact and I agree wrt the tests so I'll make a start of porting those tonight.

Wrt the files which are in upstream but not in core do you have any experience with what ought to be merged?  There are newly supported project types and databases which look like they should probably be merged, but there are still more sources.  If not all of it is appropriate for the merge then perhaps we could look at moving future development to one or many ELPA packages.

I'd like to help with this. Perhaps doing some of the merge work, or by
running tests; let me know.

Hi Stephe,

Great!  I could use all the help I can get :-)

Our main concern is to maintain the commit history and I think that my
original approach of merging to CEDET and then back creates too much
noise.  So I'm now considering a new approach and would value your
involvement if we can work out the details.

I think that the best way to go about this is to move everything in the
CEDET project into folders which mirror their destination in core.
Changes will be required for:
 - The grammar files, which need to be in admin/grammars
 - The tests, which need to be in test/manual/cedet
 - The documentation files, which need to move to doc/misc (and
   should probably be flattened.)

Once moved we commit, add CEDET as a remote of Emacs and merge
CEDET/master allowing unrelated histories.  We can delete any files
which fall outside of:
 - admin/grammars
 - test/manual/cedet
 - lisp/cedet
 - doc/misc

We should also delete any added Makefiles, EDE project files and bash
scripts.

This brings us to the topic of collaborating on this change.  I'm not
aware of any strategy for merging which allows for collaboration; so
I've come up with the following hack (comments/adjustments welcome):
 1. create a staging repository for CEDET and make the requisite folder
    structure changes in it
 2. create a branch in the Emacs project and merge allowing unrelated
    histories
 3. delete any files outside of our target folders and commit with
    unresolved conflicts
 4. push up the branch and divvy out files/folders for fixing conflicts
 5. commit and push as we go

If this sounds like something you'd like to be involved in then I'll
start with steps 1.->3. and follow up when I'm done.  If anyone has
a better idea then I'm listening.

(I considered moving the tests, but they have history too and we'd have
to start splitting commits to get them across w/o the rest of upstream
CEDET.  Additionally there's nothing preventing the tests from being run
with CEDET in Emacs core.  Just start it with --no-init add the test
folder to the load path, load the relevant test file and run it.)

Kind regards,

Edward Steere

That's great, thanks. You will need to remove quite some stuff from
there that is not in Emacs, like everything Java related, the Fortran
tests, ede/arduino, cogre...

I did take a look, and the last proper merge was done on Nov 10, 2014. I
think that was right before we switched to git. I also see now that I
did the merges differently than I remembered: I had an 'emacs' branch in
the CEDET repository which mimicked the file system layout from Emacs,
and merged the new CEDET commits there. Then I made one final diff and
committed that to Emacs. So in the end, the Emacs->CEDET merged were
commit-based, but CEDET->Emacs merges were done as one commit, and I
dimly remember that Stefan was OK with that as long as we provided
proper ChangeLogs. So I think it would be OK to do it this way again.

> Wrt the files which are in upstream but not in core do you have any

Looking at the changes since Nov 10, 2014, there's the new ede/compdb
package. Otherwise, most of the changes are for Semantic and EDE, and
they are mostly by Eric and me, and it is not as much as I feared.

For now, new files should be ignored if possible, let's merge the core
files first. Then anybody can look at what else is still upstream and
create ELPA packages for it.

If you work on the test suite, I will try to merge the commits since Nov
2014.

Actually, there's one thing which really didn't get much attention
during all those years: the texi files. I'm not sure how much those
diverged between Emacs and CEDET upstream. It was always messy, since in
the initial merge not all docs were imported from upstream. So if you'd
like to take a look at the texi files, that'd be much appreciated.

Is that a good idea? If CEDET development is going to proceed inside 
Emacs from now on, why would you remove Java support?

Is it in a really bad shape?

I guess that's on SourceForge

I'm not clear what you are merging here. It should not be the whole of
CEDET; step 3 should be done first.

That gives us a shared base to work on.

Merging to the CEDET repo is not needed, since we will abandon it
anyway.

I think it will be less work to simply do the diff|patch game and fixing
a few paths along the way. Since the histories are unrelated, git cannot
really help you with the merges anyway.

I wouldn't worry too much about the history of the tests. The authorship
of the changes should be clear, but at least I don't care much for
granularity here.

Ok, I'll look at the texi files currently in SourceForge and Emacs
CEDET, and make recommendations.

CEDET's Java support was never in Emacs, and the CEDET repository will
not vanish, so we're not really removing anything. Anybody can port the
Java support to Emacs or ELPA later.

To my knowledge, nobody has been working on it for quite some time, so
I'd be surprised if it worked with today's typical Java code.

CEDET's Java support works pretty well actually. I use it every day for
my day job. It'd be great if it could be included (eventually if not
part of this) in Emacs-proper.

Of course it could be improved since it's a little out of date, but
it remains useful.

I can report the same thing: CEDET's Java support although dated in some
places is very good.  I've submitted patches which prevent the parser
from bombing out on diamond syntax and annotations as well as fixing
starry imports, but there are other areas where it's lacking,
e.g. support for static imports.

If we were to bring it up to standard and fix some debilitating
performance issues which crop up on larger projects then it would
compete with many of the projects which try to bring semantic Java
editing to Emacs with server programs.  (You can also work around the
performance problems with some hacks which limit search scope
aggressively but that's obviously not ideal.)

I don't understand what's preventing us from porting this and other
aspects of CEDET right away -- other than scope creep perhaps?  I would
advise against using upstream as a fallback though because:
 a) it's likely to receive even less attention after the merge;
 b) most of it doesn't work with the latest Emacs because of the changes
    to EIEIO in core;

Re: CEDET Merge

[Edward Steere]

Patching does sound easier.

Given that we might be moving from upstream entirely it might be worth it to keep the commit history if we can though.  I know that git won't make is easy.

If we do go with patching though, and the changes are going to appear in the changelog then how are we going to go about doing that?  Would we use the add-change-log command on all of the commits since the last merge?

One disadvantage of all of this is that git blame results would be more difficult to interpret because the change and author would be documented elsewhere.

Yes; let's get the current core CEDET merged first.

It would be best if the other useful parts of CEDET were made into ELPA
packages.

I'm happy to hear that Java support works for people. Last time I tried
it didn't even parse generics, but I don't code much in Java anymore so
I haven't tried recently.

My worry is indeed feature creep. The CEDET merge fell behind because I
couldn't keep up with the changes in Emacs, most notably the switch to
git and the extensive changes in EIEIO. The code base is very large and
complicated, so I'm against adding more code to Emacs core. Instead, we
should try to make it more modular and put support for certain languages
and project types into separate ELPA projects. This would also make it
easier to share maintainership of CEDET.

The problem with using git is that you will have to edit each commit
anyway, at least that's my experience. You usually need to fix up the
ChangeLog entries in the commit message to conform with the Emacs file
layout. Also, one needs to remove entries which touch files that are not
in Emacs, or which are from authors who haven't signed papers with the
FSF.

Things have gotten easier since the actual ChangeLog files get generated
from the commit message. I would try to manually commit the changes with
proper commit messages, so we would retain the history with the
exception of the date of the change, which would be from the day of the
merge.

Alright.  I'll get to work on porting the tests again and limit the
tests which I merge to those which will be relevant to the components
which will end up in core.

I couldn't agree more on this point.  I also think that many users are
itching to improve the aspects of CEDET which they use and that a move
like this would make strides in making the project accessible to those
kinds of contributions.  Let's get this merge done so that we can get
cracking on the ELPA projects too! :-)

This sounds like a lot of work and the outcome sounds right.

As I said in my previous email I'll make a start on the tests.

It's not that bad. 'format-patch' gives me a nice list of patches where
I can correct the paths with 'sed' and fix up the commit messages. It's
only about 100 patches, so I don't think it will take long.

Regarding the earlier point about retaining history "with the exception of the date of the change":

'git commit' takes an optional '--date' option:

   --date=<date>
     Override the author date used in the commit.

So even the date of each change could be correct.

Yes, 'git am' does that automatically. However, I always followed the
general rule that the generated ChangeLogs should have the date when the
change enters the Emacs repository, so I'm not sure if I should even
retain the original date?

AFAIK, Git records the "author date" separately from the "commit date",
so The Right Thing To Do is to use the fancy --date argument to provide
the "author date".  The ChangeLog can use the "commit date" if needed.

Yes, git tracks 'Author' and 'Committer', each with their own date. So
the ChangeLog generator script would need to use the name from 'Author'
with the date from 'Committer'. But does it actually do that? And
wouldn't it be pretty confusing to have dates in the ChangeLog that are
years apart from those in the git log?

If it doesn't, we can change it, so it's not a problem.

That's how things are, by design (tho you can tweak your "git log" to
also output the author date, if you want), so the confusion is not due
to the "--date" argument (and can be fixed after the fact if we decide
so, whereas retroactively fixing the author-date is a lot more
difficult).

I agree with David.  Making it easy to create and maintain different

That was the rule when ChangeLogs were hand-written, but since the
switch to generated ChangeLogs it does not (and cannot) apply.
Git does not record that date.

I suggest anyone working on a CEDET merge simply ignore such issues.

Git obviously does record the commit date, so there's no problem with
that rule.

The commit date has no relation to "the date when the change enters the
Emacs repository" (ie, was pushed to Savannah).

If you want a recent example of this, "make ChangeLog" and look at the
dates of "recent" concurrency entries. Some are years old.

Eg git log --fuller 0ccc5d8998a
Both git dates are 2012-08-15, but the correct date would be 2016-12-10:

It does when you commit locally before pushing.  And, as mentioned
here, there's the --date option to control that.

That doesn't mean we should drop the rule, just that some people are

I guess I'm not following this. For example, commit 
470e3028d8a741d97349faa8fdeb148d913a49d0 ("Fix the MS-Windows build") has a 
commit date of 2015-11-02 19:04:06 2015 +0200, and so "make ChangeLog" dates it 
2015-11-02. And yet this commit was merged into master on 2016-12-10, by you, as 
part of merge commit 2412a1fc05fe9f89b171d0781c2d530923f48adc ("Support 
concurrency in Emacs Lisp"). So when you say "some people are not always 
following rules", do you mean that you did this particular merge incorrectly? Or

Commit 2412a1f has its own log message (something unusual for merge
commits, AFAIK), so IMO this example exactly follows the rules as I
understand them.

Yes, that's a problem with long-living feature branches. It'd be nice if
'make ChangeLog' would use the commit date of the merge commit for all
commits that entered Emacs through a branch merge.

If that isn't easily possible, the person who does the merge could do a
filter-branch before merging, setting GIT_COMMITTER_DATE to the current
date (if 'make ChangeLog' would actually use the committer date, which
AFAICS it currently does not).

As I understand it, that's not easy since git does not prefer one branch to the 
other in a merge, so any scheme we come up with will be as likely to redate 
commits already in the master as to redate commits entering through the merge.

Something like that should work. We aren't doing that now, which causes problems 
like the confusion noted.

>(if 'make ChangeLog' would actually use the committer date, which
> AFAICS it currently does not).

gitlog-to-changelog uses %ct, not %at, for its 'git log' format, so 'make 
ChangeLog' should already be using committer date.

Having some difficulty pushing up my branch.  This is my first time
pushing up a branch on emacs.git.  My understanding is that team
membership is sufficient for access rights.

I'm getting a "connection reset by peer" error every time I try to push
as follows:

$ git push origin scratch/merge-cedet-tests
Counting objects: 2548, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (2336/2336), done.
fatal: sha1 file '<stdout>' write error: Connection reset by peer
fatal: The remote end hung up unexpectedly
error: failed to push some refs to 'git://git.savannah.gnu.org/emacs.git'

After reading a blog post I thought that it might have something to do
with the push being too large so I added the following to ~/.ssh/config
in the hopes that regular null packets would keep the connection alive.

Host git.savannah.gnu.org
  ServerAliveInterval 5

No luck though; so I tried pushing up only three commits and that failed
with the same message as well.

You are trying to push with the git protocol, not with ssh. You need to

I've just pushed up a fairly rough attempt at merging the tests in
scratch/merge-cedet-tests (it looks like tests were only ever merged to
Emacs once.)  I took the following approach:

 * I used git to format patches per test file.
 * changed the destination of the file in each patch to match the Emacs
   manual testing directory;
 * fixed any commit messages which failed the commit hook;
 * added a final commit to cleanup; which included the removal of
   duplicated test files not moved by the patching process and the
   removal of dependencies on language/project support which we're not
   merging

The consequence of this approach is that my branch will add 316 commits.
Many of the commit messages aren't up to scratch (they pass the commit
hook but don't match the requirements outlined in CONTRIBUTE).  I'm
going to have to spend some time fixing the rest of the commits.  I
wanted to ask whether we should consider squashing all 316 commits into
a "cedet-merge" commit since the changes are going to be documented in
the ChangeLog.

Finally; the tests don't run with the CEDET in Emacs.  The first failure
is caused by a missing SRecode template -- which I imagine David will
have added on his branch.  I haven't checked what happens when his and
my changes are merged.

There seems to be a misunderstanding here: The ChangeLog is generated
from the commit log and not written separately anymore.

I don't think it makes sense to fix up all the commits messages. The
commits you've merged go back to the beginning of CEDET, and I don't
think there's any sense it writing proper ChangeLogs for them now. They
are only tests, after all. However, it is very good that we have the
history on your branch, because it makes it much easier to check if all
authors have signed papers (last I asked, authors of non-trivial tests
were also required to have papers signed with the FSF).

In my opinion, once we have decided which tests to keep and fixed them,
we should squash them and commit it as a new test suite.

That's totally expected. I'll take a look at them.

Alright.  Out of interest: is there a command for generating all of the
entries for a commit range?  I'm only aware of C-x 4 a
(add-change-log-entry-other-window) which seems to generate a change log
entry for the current file and only for the latest commit.

Agreed.

I've just made some fixes to the tests this morning (I had messed up the
merge of ia-utest.el and missed the whole of the cpproot directory for
utests.)  With that change the tests run with my current Emacs (which
runs the modified CEDET that I created by merging Emacs-CEDET -> CEDET.)

To anyone who has pulled my branch, scratch/merge-cedet-tests, I'd just
ask that you git pull -f because I rewrote that branches history to
correct my mistake.

Re: CEDET Merge

[Edward John Steere]

> That's totally expected. I'll take a look at them.
>
> -David

I've just pushed another update to my branch which fixes another mistake
in ia-utest, adds an include for the unit test root file and adds test
resource files which I missed the first time round.  I've created a
local branch where I merged my branch to yours to see how we're doing.
Here's what I've found after running both the unit and integration
tests:

* Utests in Error

** EDE Security
(error "Corrupt object on disk")

This is an error caused by the changes to how EIEIO objects auto load.
They no longer include their parents as part of the auto load so all
classes and class parents which are read from file must have their
definitions loaded prior to de-serialising (this includes the entire
inheritance hierarchy for the target class).

I added the following requires to the body of `ede-proj-load' to rectify
this (it's a total hack though):

(require 'ede/proj-prog)
(require 'ede/proj-aux)
(require 'ede/proj-elisp)
(require 'ede/proj-scheme)
(require 'ede/proj-misc)
(require 'ede/proj-prog)
(require 'ede/proj-archive)
(require 'ede/proj-shared)
(require 'ede/proj-info)
(require 'semantic/ede-grammar)

Note that I haven't added this change here.

** Project Detection Tests
I think that this also has to do with the changes to how classes are
auto loaded, but I'm not sure.

Running ede: project detection tests ...
ERROR: (wrong-type-argument (or eieio-object class) nil obj)
Running ede: project detect linux extra ...
ERROR: (wrong-type-argument (or eieio-object class) nil obj)

** Test FMT
(error "Cannot open tests/test-fmt.el for format tests")

I debugged this one and it looks like it can't open test-fmt.el because
semantic mode isn't active in Emacs lisp.

** Wisent Calculator
Running wisent calculator ...
ERROR: (void-function wisent-calc-utest)

This function doesn't seem to exist in either repo (?)

** Waiting for Key Press
Running working: wait-for-keypress ...
ERROR: (void-function working-wait-for-keypress)

This function doesn't seem to be in your branch.

** Interactive Test
(error "Invalid face" modeline)

I'm not sure where this face is defined, but it is indeed undefined
during the test.

** C Parser Tests
ERROR: (error "TAG INTERNAL DIFF: :prototype-flag :enum-type")
Running semantic: C parser (ERT) ... 
ERROR: (ert-test-failed ((should (test-c-check-tags-length actual 1)) :form (test-c-check-tags-length nil 1) :value nil :explanation "Wrong number of tags. Expected: 1, actual: 0."))
Running semantic: C preprocessor ... 
ERROR: (error #("Found: >> int EDEPART (int b) << Expected: >>  int C (int b) <<" 10 13 (face font-lock-type-face) 14 21 (face font-lock-function-name-face) 23 26 (face font-lock-type-face) 27 28 (face font-lock-variable-name-face) 47 50 (face font-lock-type-face) 51 52 (face font-lock-function-name-face) 54 57 (face font-lock-type-face) 58 59 (face font-lock-variable-name-face)))

Are the new grammar files being compiled included correctly?

** Analyser Tests
ERROR: (invalid-slot-name "#<semantic-scope-cache semantic-scope-cache>" :name)

Haven't looked any further into this failure.

** SRecode Tests
ERROR: (error "Entry #<srecode-utest-output srecode-utest-output> failed; expected: --[;; An includable  we could use.
Running srecode: fields ... 
ERROR: (error "Calculated size of #<srecode-field srecode-field> was not 5")
Running srecode: project ... 
ERROR: (error "Project template not found when in project")

Haven't looked into this one either.

* Itests
Break at first tag comparison (so they should get further when the
Utests are fixed.)

Let's start this month, I can make time for it.

As a first step: What information is needed about CEDET, to correctly inject
it into the distribution tarball? I'm betting it's slightly more than just a
list of files mapped to tarball locations.

You can use 'C-x 4 A' in a diff buffer. I usually do this:

. Do 'M-x vc-dir' and choose repository

. Hit 'D' to create a diff for the directory you want to create a
  ChangeLog for

. Hit 'C-X 4 A'

David, can you add that method to emacs.git/CONTRIBUTE? Right now it

Does anyone know if the changes were brought into Emacs?  It looks
like the merge branch got reasonably far:

Hi Charles,

To my knowledge these changes never made it into Emacs.  In fact, a few
things changed since my first email:
 - David Engster got involved (he's been responsible for merges in the
   past if I remember correctly).
 - I was informed that my branch included elements of CEDET which were
   not intended to reach core (COGRE being a good example).
 - We divided up the work of merging tests and merging CEDET and since
   David had experience with this work he went ahead with the core
   elements.

At the same time as we were working on the merge we also started
discussing the possibility of changing the way that CEDET is
distributed.  In particular, we discussed the use of ELPA as a
distribution channel.  I originally argued in favour of this move
because I think that it's widely regarded that upstream CEDET is
difficult to install and setup with Emacs.  I also believe that these
difficulties in installing and setting it up have hampered it's adoption
and development (although this is mostly a suspicion based on various
blog posts which I've read about CEDET and my own experience in getting
started with, and then using it).

There were objections to making CEDET a package.  These related to the
difficulties which the maintainers have experienced in the past with
regards to supporting multiple versions of Emacs.  After some discussion
I deferred to their wisdom.  I agreed to assist with bringing the parts
of CEDET which are currently in Emacs core up to date and with the idea
that remaining pieces should probably live on in ELPA as packages.
However, the discussion continued.  There was renewed talk of developing
CEDET (as well as other larger packages which are distributed with
Emacs) separately to Emacs and that these packages should be brought in
as part of the tarball preparation step during releases (and for what
it's worth I think that this would be a better situation if we could
work through the problems raised.)

I believe that where these developments ended was with David's objection
to eventually pulling CEDET out of core (to be developed in the
aforementioned way) because of the problems which he raised in
developing it separately to Emacs core.

The problem which I face, without the help of those more experienced
than I, is that I don't have enough context on how to resolve some of
the problems which arise as part of doing a partial merge of CEDET into
core.  I'm not an expert wrt to the CEDET project -- I'm a user and an
occasional hacker who has an understanding of the project and wants to
give back, help it grow and enjoy the benefits of this growth and
improvement to Emacs.

I would be happy to discuss possibilities for continuing this
development.

I think that CEDET has more potential than that which has been exploited
thus far.  I know that there are performance problems when working with
larger projects and I know that these aren't intractable, they would
require that we continue to develop it, reconsider some of the
mechanisms by which it operates and make better use of the tools
available to us in Emacs.

Kind regards,

Edward Steere

Can you say which parts of the merge caused difficulty?  I'd like to
help move the process along, if it's possible (though I'm also not a
frequent Elisp hacker).

Also, do you know which parts of CEDET were going to be offered as
ELPA packages?  You mentioned COGRE already -- were there any others?

That's great.  I'd be interested in collaborating with you.

I think that the biggest problem which I faced was in untangling the
dependencies which had been created between code in files which exist in
both core and upstream and some of the newer files which only exist in
upstream.  Some of these dependencies don't seem to be correct.  For
example; there is now an indirect link between the parser and java
support and not in the downwards direction but from the parser up to
java support (!?)

Others dependencies appear to be valid but exist between code which
should be merged and which shouldn't.  This made my approach of trying
to preserve history very challenging because I not only had to ensure
that the roots of patches from CEDET matched the correct destination in
their new home, but I also had to resolve conflicts where they diverged
and simultaneously remove dependencies where they were built up between
those parts which were destined for core and those which were not.

Dependency issues caused problems when trying to bootstrap Emacs on my
branch which had the whole of CEDET merged.  I did receive some help
from Eli at that point, but didn't get very far before David got
involved and started to drive that side of things.

Unfortunately, this vague description is the best I can do without
diving in again.

> Also, do you know which parts of CEDET were going to be offered as

What follows is a (possibly non-exhaustive) list of the parts of CEDET
which I don't think were intended to reach core (gathered by diffing
trees and combining that with what I remember).  This is based on the
premise that if it wasn't in core previously then it shouldn't be merged
-- which is what was agreed upon.  Looking at the list though this does
exclude a lot of good stuff.
