tutorial - Cómo configurar kdiff3 como herramienta de combinación para SVN

svn tutorial español

Question

Me gustaría poder resolver conflictos usando kdiff3, cuando SVN me notifica sobre el conflicto. ¿Cómo puedo configurarlo como una herramienta predeterminada para esto?

Answer 1

Encontré este script en algún lugar que no recuerdo. pero el autor es Michael Bradley.

Mi respuesta es similar a las respuestas de Jon Ander Ortiz Durántez. Entonces, si su respuesta no funciona, tienes una copia de seguridad. Una vez intenté algo como sugirió, pero siempre producía algún error con los parámetros hasta que encontré estos scripts que resolvieron todo.

Cree un archivo de script y establezca diff-cmd = /path/to/script.sh en su ~/.subversion/config

#!/bin/bash # Return an errorcode of 0 on successful merge, 1 if unresolved conflicts # remain in the result. Any other errorcode will be treated as fatal. # Author: Michael Bradley #NOTE: all output must be redirected to stderr with "1>&2" as all stdout output is written to the output file # Must be called by subversion in "~/.subversion/config" file # Add config : "diff-cmd = /path/to/script/myKdiff3.sh" VDIFF3="kdiff3" DIFF3="diff3" DIFF="kdiff3" promptUser () { read answer case "${answer}" in "M" ) echo "" 1>&2 echo "Attempting to merge ${baseFileName} with ${DIFF}" 1>&2 $VDIFF3 $older $mine $theirs --L1 $labelOlder --L2 $labelMine --L3 $labelTheirs -o $output 1>&2 bLoop=1 if [ -f $output ]; then if [ -s $output ]; then #output succesfully written bLoop=0 fi fi if [ $bLoop = 0 ]; then cat $output rm -f $output exit 0 else echo "Merge failed, try again" 1>&2 fi ;; "m" ) echo "" 1>&2 echo "Attempting to auto-merge ${baseFileName}" 1>&2 diff3 -L $labelMine -L $labelOlder -L $labelTheirs -Em $mine $older $theirs > $output if [ $? = 1 ]; then #Can''t auto merge rm -f $output $VDIFF3 $older $mine $theirs --L1 $labelOlder --L2 $labelMine --L3 $labelTheirs -o $output --auto 1>&2 bLoop=1 if [ -f $output ]; then if [ -s $output ]; then #output succesfully written bLoop=0 fi fi if [ $bLoop = 0 ]; then cat $output rm -f $output exit 0 else echo "Merge failed, try again" 1>&2 fi else #We can automerge, and we already did it cat $output rm -f $output exit 0 fi ;; "diff3" | "Diff3" | "DIFF3" ) echo "" 1>&2 echo "Diffing..." 1>&2 $VDIFF3 $older $mine $theirs --L1 $labelOlder --L2 $labelMine --L3 $labelTheirs 1>&2 ;; "diff" | "Diff" | "DIFF" ) echo "" 1>&2 echo "Diffing..." 1>&2 $DIFF $mine $theirs -L $labelMine -L $labelTheirs 1>&2 ;; "A" | "a" ) echo "" 1>&2 echo "Accepting remote version of file..." 1>&2 cat ${theirs} exit 0 ;; "I" | "i" ) echo "" 1>&2 echo "Keeping local modifications..." 1>&2 cat ${mine} exit 0 ;; "R" | "r" ) echo "" 1>&2 echo "Reverting to base..." 1>&2 cat ${older} exit 0 ;; "D" | "d" ) echo "" 1>&2 echo "Runnig diff3..." 1>&2 diff3 -L $labelMine -L $labelOlder -L $labelTheirs -Em $mine $older $theirs #Exit with return vaule of the diff3 (to write out files if necessary) exit $? ;; "S" | "s" ) echo "" 1>&2 echo "Saving for later..." 1>&2 cat ${mine} #Exit with return vaule of 1 to force writting of files exit 1 ;; "Fail" | "fail" | "FAIL" ) echo "" 1>&2 echo "Failing..." 1>&2 exit 2 ;; "H" | "h" ) echo "" 1>&2 echo "USAGE OPTIONS:" 1>&2 echo " [A]ccept Accept $labelTheirs and throw out local modifications" 1>&2 echo " [D]efault Use diff3 to merge files (same behavior as vanilla SVN)" 1>&2 echo " [Fail] Kills the command (not suggested)" 1>&2 echo " [H]elp Print this message" 1>&2 echo " [I]gnore Keep your locally modified version as is" 1>&2 echo " [M]erge Manually merge using ${VDIFF3}" 1>&2 echo " [m]erge Same as "M" but attempts to automerge if possible" 1>&2 echo " [R]evert Revert to base version (${labelOlder})" 1>&2 echo " [S]ave Same as ''I'' but writes out rold, rnew, and rmine files to deal with later" 1>&2 echo " [diff] Type ''diff'' to diff versions $labelMine and $labelTheirsthe before making a descision" 1>&2 echo " [diff3] Type ''diff3'' to diff all three versions before making a descision" 1>&2 echo "" 1>&2 ;; * ) echo "''${answer}'' is not an option, try again." 1>&2 ;; esac } if [ -z $2 ] then echo ERROR: This script expects to be called by subversion exit 1 fi if [ $2 = "-m" ] then #Setup vars labelMine=${4} labelOlder=${6} labelTheirs=${8} mine=${9} older=${10} theirs=${11} output=${9}.svnDiff3TempOutput baseFileName=`echo $mine | sed -e "s/.tmp$//"` #Prompt user for direction while [ 1 ] do echo "" 1>&2 echo "${baseFileName} requires merging." 1>&2 echo "" 1>&2 echo "What would you like to do?" 1>&2 echo "[M]erge [A]ccept [I]gnore [R]evert [D]efault [H]elp" 1>&2 promptUser done else L="-L" #Argument option for left label R="-L" #Argument option for right label label1=$3 #Left label label2=$5 #Right label file1=$6 #Left file file2=$7 #Right file $DIFF $file1 $file2 $L "$label1" $L "$label2" & #$DIFF $file1 $file2 & #wait for the command to finish wait fi exit 0

Answer 2

El script de la respuesta de yvoyer funciona muy bien para mí, y estoy usando SVN 1.4. Creo que la respuesta anterior de Jon Ander Ortiz Durántez funciona para SVN 1.5 y posteriores, y esta secuencia de comandos funciona para versiones SVN anteriores a 1.5. Parece que hubo cambios en --diff-cmd y --diff3-cmd para la versión 1.5. Compare las secuencias de comandos en los siguientes 2 documentos SVN para ver algunas diferencias:

• svnbook.red-bean.com/en/ 1.4 /svn.advanced.externaldifftools &
• svnbook.red-bean.com/en/ 1.5 /svn.advanced.externaldifftools .

El guión de Michael Bradley es realmente útil ya que ahora si tengo un conflicto durante la svn update , entra en kdiff3 en lugar de aparecer en todo el archivo con los ">>>>>>>>" marcadores de conflicto que son tan difíciles de resolver si tienes confictos complejos. El diff3-cmd funciona tanto para fusión como para actualización.

Agrego diff3-cmd = /usr/local/bin/svndiff3 a ~/.subversion/config (o uso --diff3-cmd en la línea de cm) ya que escribí mi propia secuencia de comandos para enviar svn diff a sdiff y está especificado por --diff-cmd .

Este script está publicado en yolinux , y una versión ligeramente modificada (que maneja la fusión automática) se publica aquí Jawspeak .

Una solución que es más corta y funciona con versiones posteriores de SVN (probado en SVN 1.7.7):

Crear un script ~ / svn-merge-kdiff

#!/bin/bash

# Useful when something fails
LOG=~/svn-merge-kdiff-last-run.log
echo "arguments passed to $0: $@" > $LOG

# Now, don''t think you will get the $1, $2, etc... by referencing.
# At first, you have to copy it to an array
for i in $@; do
    args=( ${args[@]} $i )
done

echo "parsed args" >> $LOG
for i in ${args[@]}; do
    echo $i >> $LOG
done

# I keep it in case something changes
if [ "${args[1]}" == "-m" ] && [ "${args[2]}" == "-L" ] && [ "${args[3]}" == ".mine" ];then
    command="kdiff3 --L1 ${args[5]} --base ${args[9]} --L2 ${args[7]} ${args[10]} --L3 ${args[3]} ${args[8]} -o merged"
    $command
    if [[ $? -ne 0 ]]; then
        echo "$command failed" >> $LOG
        exit 1
    fi

    # You have to do this, otherwise after the merge you will see... empty file(?)
    cat merged

    rm merged
    exit 0
fi

exit -1

Enlazarlo a svn en ~ / .subversion / config

diff3-cmd = ~/svn-merge-kdiff

Answer 4

Vaya al archivo de configuración de Subversion ( /etc/subversion/config o ~/.subversion/config ), y configure la variable merge-tool-cmd con su herramienta favorita:

### Set merge-tool-cmd to the command used to invoke your external
### merging tool of choice. Subversion will pass 4 arguments to
### the specified command: base theirs mine merged
# merge-tool-cmd = merge_command

Aunque hay un problema con kdiff3 que no admite cuatro argumentos simples (SVN pasa cuatro argumentos simples a kdiff3, y no funciona), por lo general se llama con un script simple para traducir los argumentos, por ejemplo, "kdiff3caller":

#!/bin/sh
kdiff3 "$1" "$2" "$3" -o "$4"

Este problema y solución kdiff3 se explica aquí .
