Package: kcachegrind Version: 4:17.08.3-2 Severity: normal Dear Maintainer,
when opening a cachegrind file generated with valgrind, kcachegrind failed to open the file with the following message: Could not open file "cachegrind.out.2772". Check it exists and you have enough permissions to read it. strace showed that kcachegrind was able to open the file. The real reason, as it turned out, was that the commandline was very long (the result of expanding a directory full of tcpdumps with *, generating a 1MB command line). Manually editing the file to shorten the command line in the file made kcachegrind load the file. AFAICS, there are two bugs here: 1) kcachegrind giving a wrong and confusing error message (apparently, it was able to open the file just fine, but then failed to parse the contents). 2) kcachegrind not being able to parse the output of valgrind (which is the main purpose it was written for) Obviously, kcachegrind could use a better error message, and more importantly, should be able to parse the valgrind output. -- System Information: Debian Release: 9.5 APT prefers stable APT policy: (990, 'stable'), (500, 'unstable-debug'), (500, 'testing-debug'), (500, 'stable-updates'), (500, 'stable-debug'), (500, 'unstable'), (500, 'testing'), (1, 'experimental-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.14.73-041473-generic (SMP w/8 CPU cores) Locale: LANG=C, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=C (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/bash Init: systemd (via /run/systemd/system) Versions of packages kcachegrind depends on: ii kio 5.28.0-2 ii libc6 2.27-6 ii libkf5archive5 5.28.0-2 ii libkf5configcore5 5.28.0-2 ii libkf5configwidgets5 5.28.0-2 ii libkf5coreaddons5 5.28.0-2 ii libkf5i18n5 5.28.0-2 ii libkf5jobwidgets5 5.28.0-2 ii libkf5kiocore5 5.28.0-2 ii libkf5widgetsaddons5 5.28.0-3 ii libkf5xmlgui5 5.28.0-1 ii libqt5core5a 5.11.2+dfsg-3 ii libqt5dbus5 5.11.2+dfsg-3 ii libqt5gui5 5.11.2+dfsg-3 ii libqt5widgets5 5.11.2+dfsg-3 ii libstdc++6 8.2.0-8 Versions of packages kcachegrind recommends: ii graphviz 2.38.0-17 ii valgrind 1:3.13.0-2.1 Versions of packages kcachegrind suggests: ii kcachegrind-converters 4:16.08.3-1 ii khelpcenter 4:16.08.3-1 -- no debconf information
