Package: libpango1.0-udeb
Version: 1.44.7-3
Severity: grave
Tags: d-i
Justification: renders package unusable
X-Debbugs-Cc: debian-boot@lists.debian.org


In the “better late than never” department… I've completed a debugging session
that shows that upgrading libpango1.0-udeb from 1.42.4-8 to 1.44.7-3 hangs the
installer in various situations.

Interestingly, it doesn't *always* do that.

 - I know for sure this upgrade is responsible for the rescue mode
   breakage *under some locales* tracked at:

   e.g. getting a shell into the system to be rescued works fine in
   French or in German, but not in English (which hasn't any crazy fonts
   or glyphs compared to the two other ones).

 - It seems to a kind user performing many tests that this could be
   linked to the actual hardware configuration:

   (See the “For short […]” conclusion, it's priceless.)

   I'll be trying to get more results from Étienne.

 - I'm *not yet* certain this also triggers direct failures for Netinst
   images for several languages, tracked at:

   but I have a rather strong suspicion, as mentioned in:

   I'll try to confirm this in the next few days.

Chris Hofstaedtler provided some perf data, which might help figure out
what's happening for someone who's knowledgeable about pango internals:

Please keep debian-boot@lists.debian.org in the loop when replying, and
thanks for your help!

   [ Simon McVittie ]
   * Capture new-style GLib structured logging messages, ensuring that we
     stop losing messages generated by libraries using that structured
     logging (ie. GLib and Pango) instead of the old text-based logging
     (i.e. GTK 2) (Closes: #988589).
   * Postpone adding text to GtkTextView until GTK has done initial layout,
     to avoid running into an infinite loop that would result in only the
     title being displayed, and a hang of the installer (Closes: #988787).
     This fixes a number of scenarios including:
     - Hang before offering a shell in rescue mode [en] (Closes: #987377).
     - Hang immediately with Sinhala and other languages (Closes: #987449).
     - Hang in various places with Swedish (mirror selection or package
       manager configuration).
   [ Cyril Brulebois ]
   * Huge thanks to Simon McVittie for the incredible support!
   * Align the display of info messages (e.g. “Rescue mode”) to the right
     again, since Debian (logo and name) is back on the left side with the
     Homeworld theme.
   * Implement workaround to ensure info messages (e.g. “Rescue mode”) get
     displayed on the banner on the start-up screen (Closes: #882804).
