This has been consistently passing in Jammy, so I'm going to set this to Fix Released.
https://autopkgtest.ubuntu.com/packages/libs/libsoup2.4/jammy/amd64 ** Changed in: libsoup2.4 (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libsoup2.4 in Ubuntu. https://bugs.launchpad.net/bugs/1945713 Title: Flaky test brotli/basic on focal amd64? Status in libsoup2.4 package in Ubuntu: Fix Released Bug description: The brotli/basic test case periodically fails. It appears that a few retriggers can result in a pass: https://autopkgtest.ubuntu.com/packages/libs/libsoup2.4/focal/amd64 The failures look like this in autopkgtest logs: ERROR:../tests/brotli-decompressor-test.c:59:test_brotli: assertion failed ((char*)out_bytes->data == contents): ("***\nU" == "***\n") I've replaced most of the text with '***' to highlight the difference is a 'U' character appended. The test case is essentially doing a decompression of 'brotli- data/compressed.br' and comparing that it matches 'brotli- data/uncompressed.txt'. I've done this manually using the brotli cli, and the files do indeed have the same content. I've also built the package and run the test case locally in a focal lxc container on amd64: $ cd libsoup2.4-gu/debian/libsoup2.4-tests/usr/libexec/installed-tests/libsoup-2.4 $ while : ; do ./brotli-decompressor-test | grep 'brotli/basic'; sleep 0.1; done I left that to run several hundred cycles but no failures reported at all. There are a bunch of instances of this failure, here's a few for reference: https://autopkgtest.ubuntu.com/results/autopkgtest-focal/focal/amd64/libs/libsoup2.4/20210602_152107_d1d56@/log.gz https://autopkgtest.ubuntu.com/results/autopkgtest-focal/focal/amd64/libs/libsoup2.4/20210531_201241_8b1be@/log.gz https://autopkgtest.ubuntu.com/results/autopkgtest-focal/focal/amd64/libs/libsoup2.4/20200508_211619_2aec8@/log.gz That last link is the earliest instance I've been able to find. You'll notice in the second two links they also have a failure "not ok 2 /ssl/tls-interaction", but the first link shows only the brotli failure. Interestingly, I've not found instances of this failure against other architectures than amd64, nor have I seen it on releases other than focal. No dice from googling for bug reports or other reports of test failures with libsoup2.4 + brotli. The test's code is doing this, basically: SoupBrotliDecompressor *dec = soup_brotli_decompressor_new (); do { result = g_converter_convert (G_CONVERTER (dec), in_buf, length, out_buf, sizeof out_buf, 0, &bytes_read, &bytes_written, &error); g_byte_array_append (out_bytes, out_buf, bytes_written); in_buf += bytes_read; length -= bytes_read; } while (result == G_CONVERTER_CONVERTED); soup_brotli_decompressor's code is here: https://gitlab.gnome.org/GNOME/libsoup/-/blob/master/libsoup/content- decoder/soup-brotli-decompressor.c But I'm not spotting anything that would obviously cause a 'U' to be randomly appended sometimes. And why 'U'? UINT? Unknown? User error? There are some interesting bug reports in GNOME about brotli in libsoup's bug tracker (e.g. #106, #146, #119, and #193), but none that match this.
