# perf bash and zsh completion
License cleanup: add SPDX GPL-2.0 license identifier to files with no license Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

perf tools: Avoid confusion with preloaded bash function for perf bash completion Since some functions (e.g. '_get_comp_words_by_ref()') in perf bash completion script are originally taken from git bash completion script, these functions may be preloaded before perf bash completion script runs. In order to avoid repeating loading the same function twice, some test constraints are used before these function definitions in the perf bash completion script (e.g. 'type _get_comp_words_by_ref &>/dev/null ||'). The problem is that, if these functions in perf bash completion script are changed for some reason, perf will still use the preloaded bash functions rather than the customized functions of its own. As a result, the perf bash completion will behave incorrectly. To get rid of this problem, a flag can be defined to determine the proper situation. And to avoid overwriting the preloaded functions, the names of these functions in perf bash completion script should be renamed to the perf-customized ones. Example: Before this patch: $ type _get_comp_words_by_ref _get_comp_words_by_ref is a function _get_comp_words_by_ref () { local exclude flag i OPTIND=1; local cur cword words=(); local upargs=() upvars=() vcur vcword vprev vwords; while getopts "c:i:n:p:w:" flag "$@"; do case $flag in c) vcur=$OPTARG ;; i) vcword=$OPTARG ;; n) exclude=$OPTARG ;; p) vprev=$OPTARG ;; w) vwords=$OPTARG ;; esac; done; while [[ $# -ge $OPTIND ]]; do case ${!OPTIND} in cur) vcur=cur ;; prev) vprev=prev ;; cword) vcword=cword ;; words) vwords=words ;; *) echo "bash: $FUNCNAME(): \`${!OPTIND}': unknown argument" 1>&2; return 1 ;; esac; let "OPTIND += 1"; done; __get_cword_at_cursor_by_ref "$exclude" words cword cur; [[ -n $vcur ]] && { upvars+=("$vcur"); upargs+=(-v $vcur "$cur") }; [[ -n $vcword ]] && { upvars+=("$vcword"); upargs+=(-v $vcword "$cword") }; [[ -n $vprev && $cword -ge 1 ]] && { upvars+=("$vprev"); upargs+=(-v $vprev "${words[cword - 1]}") }; [[ -n $vwords ]] && { upvars+=("$vwords"); upargs+=(-a${#words[@]} $vwords "${words[@]}") }; (( ${#upvars[@]} )) && local "${upvars[@]}" && _upvars "${upargs[@]}" } As shown above, the _get_comp_words_by_ref is the preloaded function in fact, rather than the function defined in perf-completion.sh. So if we happen to change the function for some reason, the result will behave in a wrong state. After this patch: We can set preload_get_comp_words_by_ref="false" to not use the preloaded function. Instead, it will use the function defined in perf-completion.sh, which is renamed as __perf_get_comp_words_by_ref to avoid overwriting the preloaded function _get_comp_words_by_ref. $ type __perf_get_comp_words_by_ref __perf_get_comp_words_by_ref is a function __perf_get_comp_words_by_ref () { local exclude cur_ words_ cword_; if [ "$1" = "-n" ]; then exclude=$2; shift 2; fi; __my_reassemble_comp_words_by_ref "$exclude"; cur_=${words_[cword_]}; while [ $# -gt 0 ]; do case "$1" in cur) cur=$cur_ ;; prev) prev=${words_[$cword_-1]} ;; words) words=("${words_[@]}") ;; cword) cword=$cword_ ;; esac; shift; done } As shown above, the function __perf_get_comp_words_by_ref is loaded and can work this time. Note that we do not change the original behavior when those functions are not preloaded before perf bash completion script runs. In this case, although the flag is set to "true", the code will still change it to "false" to use the function defined in perf-completion.sh.

perf tools: Fix the bash completion problem of 'perf --*' The perf-completion.sh uses a predefined string '--help --version --exec-path --html-path --paginate --no-pager --perf-dir --work-tree --debugfs-dir' for the bash completion of 'perf --*', which has two problems: Problem 1: If the options of perf are changed (see handle_options() in perf.c), the perf-completion.sh has to be changed at the same time. If not, the bash completion of 'perf --*' and the options which perf really supports will be inconsistent. Problem 2: When typing another single character after 'perf --', e.g. 'h', and hit TAB key to get the bash completion of 'perf --h', the character 'h' disappears at once. This is not what we want, we wish the bash completion can return '--help --html-path' and then we can continue to choose one. To solve this problem, we add '--list-opts' to perf, which now supports 'perf --list-opts' directly, and its result can be used in bash completion now. Example: Before this patch: $ perf --h <-- hit TAB key after character 'h' $ perf -- <-- 'h' disappears and no required result After this patch: $ perf --h <-- hit TAB key after character 'h' --help --html-path <-- the required result Signed-off-by: Yunlong Song <yunlong.song@huawei.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1425032491-20224-8-git-send-email-yunlong.song@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

perf tools: Fix the bash completion problem of 'perf --*' The perf-completion.sh uses a predefined string '--help --version --exec-path --html-path --paginate --no-pager --perf-dir --work-tree --debugfs-dir' for the bash completion of 'perf --*', which has two problems: Problem 1: If the options of perf are changed (see handle_options() in perf.c), the perf-completion.sh has to be changed at the same time. If not, the bash completion of 'perf --*' and the options which perf really supports will be inconsistent. Problem 2: When typing another single character after 'perf --', e.g. 'h', and hit TAB key to get the bash completion of 'perf --h', the character 'h' disappears at once. This is not what we want, we wish the bash completion can return '--help --html-path' and then we can continue to choose one. To solve this problem, we add '--list-opts' to perf, which now supports 'perf --list-opts' directly, and its result can be used in bash completion now. Example: Before this patch: $ perf --h <-- hit TAB key after character 'h' $ perf -- <-- 'h' disappears and no required result After this patch: $ perf --h <-- hit TAB key after character 'h' --help --html-path <-- the required result Signed-off-by: Yunlong Song <yunlong.song@huawei.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1425032491-20224-8-git-send-email-yunlong.song@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

perf tools: Avoid confusion with preloaded bash function for perf bash completion Since some functions (e.g. '_get_comp_words_by_ref()') in perf bash completion script are originally taken from git bash completion script, these functions may be preloaded before perf bash completion script runs. In order to avoid repeating loading the same function twice, some test constraints are used before these function definitions in the perf bash completion script (e.g. 'type _get_comp_words_by_ref &>/dev/null ||'). The problem is that, if these functions in perf bash completion script are changed for some reason, perf will still use the preloaded bash functions rather than the customized functions of its own. As a result, the perf bash completion will behave incorrectly. To get rid of this problem, a flag can be defined to determine the proper situation. And to avoid overwriting the preloaded functions, the names of these functions in perf bash completion script should be renamed to the perf-customized ones. Example: Before this patch: $ type _get_comp_words_by_ref _get_comp_words_by_ref is a function _get_comp_words_by_ref () { local exclude flag i OPTIND=1; local cur cword words=(); local upargs=() upvars=() vcur vcword vprev vwords; while getopts "c:i:n:p:w:" flag "$@"; do case $flag in c) vcur=$OPTARG ;; i) vcword=$OPTARG ;; n) exclude=$OPTARG ;; p) vprev=$OPTARG ;; w) vwords=$OPTARG ;; esac; done; while [[ $# -ge $OPTIND ]]; do case ${!OPTIND} in cur) vcur=cur ;; prev) vprev=prev ;; cword) vcword=cword ;; words) vwords=words ;; *) echo "bash: $FUNCNAME(): \`${!OPTIND}': unknown argument" 1>&2; return 1 ;; esac; let "OPTIND += 1"; done; __get_cword_at_cursor_by_ref "$exclude" words cword cur; [[ -n $vcur ]] && { upvars+=("$vcur"); upargs+=(-v $vcur "$cur") }; [[ -n $vcword ]] && { upvars+=("$vcword"); upargs+=(-v $vcword "$cword") }; [[ -n $vprev && $cword -ge 1 ]] && { upvars+=("$vprev"); upargs+=(-v $vprev "${words[cword - 1]}") }; [[ -n $vwords ]] && { upvars+=("$vwords"); upargs+=(-a${#words[@]} $vwords "${words[@]}") }; (( ${#upvars[@]} )) && local "${upvars[@]}" && _upvars "${upargs[@]}" } As shown above, the _get_comp_words_by_ref is the preloaded function in fact, rather than the function defined in perf-completion.sh. So if we happen to change the function for some reason, the result will behave in a wrong state. After this patch: We can set preload_get_comp_words_by_ref="false" to not use the preloaded function. Instead, it will use the function defined in perf-completion.sh, which is renamed as __perf_get_comp_words_by_ref to avoid overwriting the preloaded function _get_comp_words_by_ref. $ type __perf_get_comp_words_by_ref __perf_get_comp_words_by_ref is a function __perf_get_comp_words_by_ref () { local exclude cur_ words_ cword_; if [ "$1" = "-n" ]; then exclude=$2; shift 2; fi; __my_reassemble_comp_words_by_ref "$exclude"; cur_=${words_[cword_]}; while [ $# -gt 0 ]; do case "$1" in cur) cur=$cur_ ;; prev) prev=${words_[$cword_-1]} ;; words) words=("${words_[@]}") ;; cword) cword=$cword_ ;; esac; shift; done } As shown above, the function __perf_get_comp_words_by_ref is loaded and can work this time.

_get_comp_words_by_ref -n =:, cur words cword prev
perf tools: Avoid confusion with preloaded bash function for perf bash completion Since some functions (e.g. '_get_comp_words_by_ref()') in perf bash completion script are originally taken from git bash completion script, these functions may be preloaded before perf bash completion script runs. In order to avoid repeating loading the same function twice, some test constraints are used before these function definitions in the perf bash completion script (e.g. 'type _get_comp_words_by_ref &>/dev/null ||'). The problem is that, if these functions in perf bash completion script are changed for some reason, perf will still use the preloaded bash functions rather than the customized functions of its own. As a result, the perf bash completion will behave incorrectly. To get rid of this problem, a flag can be defined to determine the proper situation. And to avoid overwriting the preloaded functions, the names of these functions in perf bash completion script should be renamed to the perf-customized ones. Example: Before this patch: $ type _get_comp_words_by_ref _get_comp_words_by_ref is a function _get_comp_words_by_ref () { local exclude flag i OPTIND=1; local cur cword words=(); local upargs=() upvars=() vcur vcword vprev vwords; while getopts "c:i:n:p:w:" flag "$@"; do case $flag in c) vcur=$OPTARG ;; i) vcword=$OPTARG ;; n) exclude=$OPTARG ;; p) vprev=$OPTARG ;; w) vwords=$OPTARG ;; esac; done; while [[ $# -ge $OPTIND ]]; do case ${!OPTIND} in cur) vcur=cur ;; prev) vprev=prev ;; cword) vcword=cword ;; words) vwords=words ;; *) echo "bash: $FUNCNAME(): \`${!OPTIND}': unknown argument" 1>&2; return 1 ;; esac; let "OPTIND += 1"; done; __get_cword_at_cursor_by_ref "$exclude" words cword cur; [[ -n $vcur ]] && { upvars+=("$vcur"); upargs+=(-v $vcur "$cur") }; [[ -n $vcword ]] && { upvars+=("$vcword"); upargs+=(-v $vcword "$cword") }; [[ -n $vprev && $cword -ge 1 ]] && { upvars+=("$vprev"); upargs+=(-v $vprev "${words[cword - 1]}") }; [[ -n $vwords ]] && { upvars+=("$vwords"); upargs+=(-a${#words[@]} $vwords "${words[@]}") }; (( ${#upvars[@]} )) && local "${upvars[@]}" && _upvars "${upargs[@]}" } As shown above, the _get_comp_words_by_ref is the preloaded function in fact, rather than the function defined in perf-completion.sh. So if we happen to change the function for some reason, the result will behave in a wrong state. After this patch: We can set preload_get_comp_words_by_ref="false" to not use the preloaded function. Instead, it will use the function defined in perf-completion.sh, which is renamed as __perf_get_comp_words_by_ref to avoid overwriting the preloaded function _get_comp_words_by_ref. $ type __perf_get_comp_words_by_ref __perf_get_comp_words_by_ref is a function __perf_get_comp_words_by_ref () { local exclude cur_ words_ cword_; if [ "$1" = "-n" ]; then exclude=$2; shift 2; fi; __my_reassemble_comp_words_by_ref "$exclude"; cur_=${words_[cword_]}; while [ $# -gt 0 ]; do case "$1" in cur) cur=$cur_ ;; prev) prev=${words_[$cword_-1]} ;; words) words=("${words_[@]}") ;; cword) cword=$cword_ ;; esac; shift; done } As shown above, the function __perf_get_comp_words_by_ref is loaded and can work this time.
