Currently packaged emacs-telega is v.0.8.03, the
telega-tdlib-max-version defined for that version is "1.8.0" [1]

The latest version of telega.el in master (defined as Version 0.8.44 in
metadata) [2]: it does support tdlib 1.8.4, but unfortunately uspream is
not releasing (via git tag) since v.0.8.03: should we use the commit
hash c547477be39298eabf8e67f0116a115771f2ee0b to upgrade emacs-telega to
the last upstream version?

Meanwhile, since tdlib now is only used by emacs-telega[-server] we
should temporary revert this commit, unless there are security concerns.

WDYT?

Thanks! Gio'

Hi Giovanni,

Thanks for investigating.  I think you're right.  Either reverting or
updating the emacs-telega package definition (needs to be tested still).

I'd revert it right away, since it's broken as of now.  I don't have
commit access.  Ludovic, could you please do it?

Thanks.

I also updated the related bug#57017: tdlib v.1.8.4 has not been
released yet (see bug#57017 for details), the last stable release of
tdlib is still 1.8.0, and consequently the last stable release of
emacs-telega is still 0.8.03 [1] that is compatible with thed tdlib
version

> I'd revert it right away, since it's broken as of now.  I don't have

unfortunately the bug is worst than I imagined: I was (easily) able to
switch my dedicated emacs profile to a previously running version (via
--switch-generation=) and started a new emacs named server

running "M-x telega" I get this in the **Messages** buffer:

--8<---------------cut here---------------start------------->8---

[6]telega-server: annullato
Error running timer ‘telega-server--idle-timer-function’: (error "telega-server is not running")

--8<---------------cut here---------------end--------------->8---

("annullato" means aborted)

this is the error I get in ~/.telega/telega-server.log:

--8<---------------cut here---------------start------------->8---

[ 0][t 4][1662729492.673026323][LogEvent.h:135][#1][!Td][&version() < static_cast<int32>(Version::Next)]	Wrong version 41

--8<---------------cut here---------------end--------------->8---

AFAIU when I ran telega with the new tdlib verson, the database got
upgraded and the new database version is not compatible with the old
tdlib library; there is an old (Mar 2021) telega.el issue that helped me
understand this one: https://github.com/zevlg/telega.el/issues/276

If I'm not getting it wrong, reverting the "offending" patch and
restoring tdlib to 1.8.0 is not enough for people like us who already
upgraded tdlib (and started telega), we need to restore from backups.

WDYT?

Happy hacking! Gio'


[1] I had a quich chat with Zajcev Evgeny on the telaga Telegram channel
and he confirmed that he is still not releasing a new version since he
is wating a new official tdlib release

Hi Giovanni,

Great investigation, thanks.

I'm a bit confused when you say "restore from backups".  Are you saying
that, for those who have already upgraded tdlib, it's not sufficient to
simply switching to an older generation?

I did it: i switched (--switch-generation=) my profile to a previous
generation (when emacs-telega was running) and telega-server
(automatically started by telega) is not starting anymore, with the
error I reported in my previous message

André please could you try to switch back to a previous profile
generation and test it, reporting the errors you get in Emacs *Messages*
buffer in ~/.telega/telega-server.log (unless you configured another
telega directory)?

Thanks, Gio'

Hi Giovanni,

I switched back to a previous profile generation and I was able to start
the telega server only after deleting all database files located at
~/.telega/.  Before doing that I was also getting errors.

Some things look off in in *Telega Root* buffer tough, and I can't use
emacs-telega as before.  I can't say it's working properly.

Does this make sense?  Can you reproduce what I've detailed?

Thanks.

Hi André

I was able to swith back to a previous profile generation and use
emacs-telega again, see below

current emacs-telega is still broken, AFAIK

the last few lines of ~/.telega/telega-server.log could have been
useful so we could compare them with mine, but nevermind

AFAIU just deleting the database files could not be enough since there
could be some "status" (other files in ~/.telega) giving problems

have you tryed renaming the whole ~/.telega folder to ~/.telega.BACKUP?

> Does this make sense?

Yes it makes sense

> Can you reproduce what I've detailed?

Yes, I renamed the telega folder as suggested above and started
emacs-telega;  I had to authenticate my desktop client again and now
AFAIU all is working as before

Hi Giovanni!

It's working for me too, following your steps!

So, I believe we're agreeing that the commit we referred to should be
reverted.  Correct?

Thanks.

Fine, so we have an easy procedure to "roll back" the telega-server
status folder; this means a new desktop application authentication that
will appear as a new "device" (probably followed by old "device"
deletion, for security) in Telegram, but AFAIU this is not a problem for
most of the users

IMHO yes, we should revert the tdlib upgrade /or/ keep a packaged
tdlib@1.8.0 used by emacs-telega v. 0.8.3

AFAIU soon (TM) a new release of emacs-telega should be published
(tagged) so eventually the next step could be to upgrade emacs-telega
(as soon as it is released)

Anyway, IMHO both tdlib and emacs-telega should be built from official
releases and not from specific commits, for users who wish to run
emacs-telega/tdlib from specific commits more recent than current
"stable", I propose to create tdlib-next and emacs-telega-next

[...]

If I don't get it wrong, I still have commit access to the guis repo so
I could revert the commit on tdlib, but I'd like to have an OK.

Ludo' WDYT please?

Thanks, Gio'

I think we can reintroduce tdlib 1.8.0 (in addition to the latest
version currently available) for use by emacs-telega; we’ll remove it
eventually when it becomes unnecessary.

Could you send a patch?

Note that I don’t use tdlib and emacs-telega, so I’ll apply whatever
seems appropriate to you.  :-)

Thanks,
Ludo’.

I just sent a patch: bug#58003

unfortunately I'm not able to compile emacs-telega, see the patch cover
letter for details

What about update emacs-telega to
0.8.44(https://github.com/zevlg/telega.el/commit/2d77c131856c9387a28dd6e4a15cef87029c3055)
?

I know the guidelines of Guix is package the stable release of software.
But I found that the telega in current Guix is partially broken(e.g.
messages with reactions is displayed as "TODO: messageUnsupported")

But the author of telega doesn't tag a release frequently. If we only
use the official release, it will be outdated.

I understand your needs but, as I already mentioned in a previous
message:

>> [1] I had a quich chat with Zajcev Evgeny on the telaga Telegram
>> channel and he confirmed that he is still not releasing a new version
>> since he is wating a new official tdlib release

so 0.8.44 is "unstable", as is "unstable" tdlib 1.8.4 as also reported
in bug#57017

what about to have emacs-telega /and/ tdlib packages using a stable
relase and adding emacs-telega-unstable and tdlib-unstable packages
using newer commits?

WDYT?
