From fedora bug: https://bugzilla.redhat.com/show_bug.cgi?id=1323144 Description of problem: When connecting with spice-html5 to Fedora 23 Workstation VM and GDM is shown, the client becomes very unresponsive and the Version-Release number of selected component (if applicable): Master branch from github How reproducible: Open the example client and connect to a fedora 23 virtual machine. Steps to Reproduce: 1. Created a boxes machine in Fedora 23 2. Installed Fedora 23 workstation from official ISO 3. Updated packages 4. Opened spice-html5 example client webpage 5. Connected to localhost:5900 6. Wait for machine to boot to GDM Actual results: Very slow response and cursor not being shown Expected results: Acceptable responsiveness and cursor beign shown to know where we are clicking Additional info: The package Fleet Commander at https://github.com/fleet-commander/fc-admin uses an implementation of spice-html5 for connecting to virtual machines using libvirt/spice and we are having this problem too.

Created attachment 138433 [details] [review] 0001-Check-if-streams-array-exists-in-handle_draw_jpeg_on.patch -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - From b3dd9879786bfd9990d83b1d58581b94944cba14 Mon Sep 17 00:00:00 2001 From: Joel Purra <mig@joelpurra.se> Date: Thu, 29 Mar 2018 20:00:51 +0200 Subject: [PATCH 1/1] Check if streams array exists in handle_draw_jpeg_onload - - It seems `SpiceDisplayConn` does not always have the array `this.o.sc.streams` set. - - It also seems (stream?) images can be loaded before `streams` is set. - - Without `streams`, or the specific stream matching `this.o.id`, `this.o.sc.streams[this.o.id].frames_loading` cannot be accessed. - - The check for the specific stream woth `this.o.id` is already in place, this patch adds a check for `this.o.sc.streams` in `handle_draw_jpeg_onload`. - - There might be a better place to ensure that `this.o.sc.streams` is initialized; this quick fix saved my bacon today though. Might be related to, and perhaps fix: - - https://bugs.freedesktop.org/show_bug.cgi?id=94776 - - https://bugzilla.redhat.com/show_bug.cgi?id=1323144 Signed-off-by: Joel Purra <mig@joelpurra.se> - --- display.js | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/display.js b/display.js index 7719b23..dbeffea 100644 - --- a/display.js +++ b/display.js @@ -883,7 +883,7 @@ function handle_draw_jpeg_onload() var temp_canvas = null; var context; - - if (this.o.sc.streams[this.o.id]) + if ("streams" in this.o.sc && this.o.sc.streams[this.o.id]) this.o.sc.streams[this.o.id].frames_loading--; /*------------------------------------------------------------ - -- 2.16.2 -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEE8RgKxBDfUGwbqSwEHZ+L2wzvqUAFAlq9MtkACgkQHZ+L2wzv qUAjaA//fscPpzFbi3B+XMjl54n7iRoHgVofrV4jC3TE2ff7FsKvLMYOonKBF/fh k1ZH+bffHTZ1lWAjZX7J4e31wmxa/u8nsJejVDZcD5eQzL7OKgkFO4ZZdmY2ljNF qYZAKjEw17mC4XuHdHT6pF2vnvIR/rIBH/vhIs1KJRie8RHTT6K91m8GaBwS5QKG ejzPhS1TyBXlw/dl3AnA2aA2tRs39oDn/pnmsFSG74JpsMQDxi/QD6rh+bJ8NJJD 7qviZ7mOtE2dyauJMFedNkKHJWrONlrybdSbtFK/EZLODqrYVIe+EewOy7Aa6Sqx Ky2zdtavPWAt2G6PHH4VjTHDsEsdNEC6UsYucBxSMGQ8CKazZH1EqhKHoIDc7k/j meOvJZGb0kyPRN9zUe42sn4YOb0XwgmdzRlFHuIMg0hUYDQxjDkH1WNoDGSM1YMl Nc8kbDgSpssn0oij2Oi8p8M5/HPTG1Ck26gH0wmrMqsNuzvTCGFE52ikfdYP/5Og Am3iGV+ImZ8Lo6/vvMv6aihA/kKUC42NE+MrLHPMc5x+/q/f+pkRMS48Pxb1dWpO T7dY9l83+N5cbPoeQGQrtKmV1HpI4+JGWJzwSnq/9nAm8/XmpUFRY8Gtj2FHI9zP ZTM9mf9VqUJyDte/uKxgd/J4cWEFDs37GCxqKUr8JaFKZTzwRC4= =mGUG -----END PGP SIGNATURE-----
Experienced the same symptoms. - Using spice-html5 from macOS to connect to a Debian machine. - Can connect without a problem, and can see the Debian machine console login prompt. - Can not enter the username nor interact in any other way. Using the browser's developer console, I found an array reference error triggered again and again; luckily it was easy to fix. See patch (which I accidentally added as a comment with my pgp signature) before this comment.
