Therefore replace with " ". 2014.02.10 v.6.4 + Rely on desktop manager (e.g. Gnome) and user to perform disc mounting (discontinue internal mount commmand causing a fight with Gnome). + Update method used to find DVD/BlueRay devices. 2013.04.01 v.6.3.1 + Display online help file from menu Help > contents. 2012.11.01 v.6.3 + Replaced deprecated GTK functions with new versions. + Improved clarity of some GUI and report texts. 2012.03.17 v.6.2 + Bugfix: Some DVDs have a top directory with embedded blanks. These would not work because "\040" was being substituted. Fixed. 2012.02.01 v.6.1 + Dkopp was converted to use GTK3 and Cairo. It will no longer build or install on older Linux distros lacking these libraries. + Bugfix: /etc/mtab is no longer reliable for DVD mount status. Using /proc/mounts has improved the reliability of DVD mounting. + RPM packages are built using Fedora and rpmbuild instead of alien. 2011.10.20 v.6.0 + Code cleanup for compiler warnings from GCC 4.6 (Ubuntu 11.10). + Removed the use of GTK functions within threads. + DEB package is now made by dkpg and RPM is made from DEB via alien. 2011.08.17 v.5.9.2 + Compensation added for hung DVD/BD drive after growisofs is done. The drive can become unresponsive (ignores mount commands), but ejecting and reloading cures the problem and allows the verify operation to proceed. 2011.08.08 v.5.9.1 + The option was added to abort/retry/ignore errors from growisofs. Sometimes nothing is really wrong, or the error is temporary and will not recurr if the last operation is repeated after a short delay. Interference by Gnome auto-mount cannot always be stopped. These error statuses vary with new releases of the kernel, Gnome, and growisofs, and can also vary by DVD/BD hardware. 2011.08.01 v.5.9 + Mount logic changed to deal better with automatically mounted media. Gnome will mount the DVD/BD even if dkopp issues the mount command. Dkopp gets "broken pipe" status. This wierdness is simply accepted. 2011.05.01 v.5.8 + Packages are now built with Ubuntu 10.04 instead of 8.10. The default install location is now /usr/ instead of /usr/local/. + Growisofs always returns a bad status for Blue-Ray media, even though they are always OK (so far). The user message was changed to state that the media is likely OK and give the option to continue accordingly. The verify phase will determine the true media status afterwards. 2011.02.20 v.5.7 + For full backups, do not mount BD/DVD (stop meaningless error messages). + For incremental backup or verify: if mount fails, eject and mount again (try to recover from Gnome mount contention, "broken pipe" etc.) 2010.12.05 v.5.6 + Bugfix: quote DVD label to prevent failure from imbedded blanks. + Big backup job with multiple DVDs: add recovery from write or verify error: repeat a failed DVD in-sequence before starting the next one. + Workaround: "Unknown error 18446744073709551615" from the stat() function turns out not to be a real error and can be ignored. + An elementary man page was added. Details are in the user guide. 2010.09.13 v.5.5 + Bugfix: -script and -nogui failed to work if script is verify only. + Improved diagnostics and progress monitoring for -nogui option. 2010.08.21 v.5.4 + A button [root] was added to the toolbar. This restarts the application with root privileges if the queried password (sudo) is correct. 2010.07.15 v.5.3 + Dkopp was tested with Blue-Ray media, recordable (BD-R) and re-writeable (BD-RE). It works without modification (i.e. growisofs works). The job size reasonableness check was raised to 50 GB. The menus and docs were revised to indicate that BD as well as DVD media can be used. + Setting the DVD/BD mount point was removed from backup job edit and restore job edit. This is now done only in the dialog to select the DVD/BD drive and override the default mount point. 2010.05.24 v.5.2 Output formats for several reports were slightly improved. 2010.03.01 v.5.1 + Simplify how DVD labels and mount points are handled, in an attempt to play better with various DVD auto-mount environments. Ubuntu 9.10 auto-mounts DVDs that dkopp requests to mount, causing a small war. Ubuntu 10.04 creates /media/xxxx when a DVD with label xxxx auto mounts: the location is therefore variable. Dkopp now looks only for the DVD device and uses an existing mount point. If DVD auto-mounting is enabled, start dkopp after the auto-mount completes. Mount points in existing dkopp job files are now ignored and can be removed to avoid an innocuous diagnostic. You can use gconf-editor to prevent auto-mounting: keys are: /apps/nautilus/preferences/media_automount. + The mod time resolution on DVD files has recently changed from 0.001 to 1.0 seconds, and apparently only for hidden files (genisoimage?). Dkopp now regards mod time differences under 1 second as equivalent. 2009.12.26 v.5.0 + Support non-GUI mode for command-line / deferred execution (cron). (e.g. $ dkopp -nogui -run /.../my-dkopp.job) 2009.10.30 v.4.8 + Set file exclusion date to 1970.01.01 by default (older files cannot be date compared with disk files). + Avoid dialog to request DVD mount if a script file is running and verify that the DVD is present before continuing. + If DVD mount point is missing, create it and continue. + Unmount DVD: use mount point instead of device in umount command. 2009.07.13 v.4.7.1 fix compile errors introduced by gcc 4.4 2009.04.25 v.4.7 Another change in DVD mounting to get around newest Linux issue: DVD mount command can lock-up (hang) if a DVD is blank or newly formatted. Therefore, in the case of a full backup, a mount attempt is no longer made (this was done to show the label and any prior backup usage data). For incremental backups the mount is still required, so do not try an incremental backup with a blank DVD (which makes no sense anyway). 2009.04.12 v.4.6 + An additional file selection method is provided: include only files having a creation or modification date on or after a given date. + Inconsistencies in the handling of symlinks have been cleaned up (see the technical note in the user guide). + Bugfix: an excluded file that is also inaccessible or exceeds 4 GB in size caused a segment fault. 2009.03.30 v.4.5 + DVD speed factor was added to the job edit. The user may elect a lower speed than the default for the DVD medium, to increase DVD reliability and longevity. Leave blank or zero to use the default speed. + The Linux program "udevinfo" has recently become "udevadm info". Dkopp was modified to use whichever variant works. 2008.11.03 v.4.4 Detect if the DVD is already mounted and use as-is (set backup directory to match mount point). The dkopp backup job should use the same device name that Gnome (or other desktop) uses, e.g. /dev/scdo instead of /dev/sr0. Otherwise dkopp will try to redundantly mount the device. It is best to let the auto-mount complete before starting a backup job, to avoid a tug-of-war as dkopp tries to mount the device in parallel. 2008.06.01 v 4.3 + change from build script to conventional makefile + name change from dkop to dkopp 2008.04.20 v.42 + code changes for compatibility with recent gcc, c-lib, and GTK2 + changes to DVD mount logic to get around the latest driver flakeyness and mount interference from Gnome 2008.03.11 v.41 + added DVD eject and re-mount when DVD mount fails after growisofs - growisofs can leave the DVD totally unresponsive, causing verify after backup to fail. The backup is usually OK and verify will work normally after the DVD has been ejected and reloaded. - happens with DVD+R and -R, but not with DVD+RW (on my 2 computers) - this workaround works for my desktop but not for my notebook (but it does work if the DVD tray is manually pushed back in) 2008.02.04 v.40 + replace DVD eject between backup and verify with sleep(3) + mount. 2008.01.29 v.39 + separate build scripts for downloaders and package builders + code changes to get application directories from build script 2008.01.20 v.38 + ignore mount error if full backup (likely a blank DVD) + ignore failed eject command - some systems cannot do software eject 2008.01.01 v.37 + made several changes for 64-bit architecture compatibility, including sequence sensitivity of #include statements leading to runtime crash in gtk_dialog_new_with_buttons() + build script allows user choice of install location and desktop launcher 2007.12.11 v.36 + workaround for defective lib function strerror_r() and BSD compatibility 2007.12.10 v.35 + fix compile errors for 64-bit architecture + code cleanup for newest gcc compiler warnings + changed logic of verify thorough - now works independently of backup job + error messages to stderr are now captured and put on the screen 2007.11.20 v.34 + trap mkisofs / genisoimage errors not reported in growisofs status (can make a bad DVD look good) 2007.11.15 v.33 + new GTK requirement: if (! g_thread_supported()) g_thread_init(0); 2007.11.12 v.32 + stop propagation of DVD label suffix (dkop:A:A:A...) if same DVD is re-used for multiple full backups + locale related library changes 2007.10.15 v.31 + fix significant bug in thorough verify: files not compared 100% + list include and exclude records at the start of the history log file + don't lose comment records in job file + eliminate "end" record in job file (end is EOF) 2007.08.29 v.30 + move DVD label setting from job edit to separate menu item + DVD mount no longer overwrites a previously set backup job label 2007.08.23 v.29 + stop exotic files names with special characters like \r from trashing output formats + optional user input of DVD label + provide searchable backup log file (time/date, label, list of files) + query to find all backup DVDs containing desired files, using wildcards 2007.07.13 v.28 + accept job file on command line (without -job) (per Linux convention) + allow retry of a failed DVD within a multiple-DVD backup job + correct progress tracking for multiple-DVD jobs 2007.07.04 v.27 .27b + back to using bash for DVD mount (undocumented black magic works better) + follow Linux convention for application files in /home/user/.dkop/ or /root/.dkop/ (move your job files here for convenience) + improve clarity of command outputs and reports + allow show / hide of hidden files in job edit file chooser dialog 2007.05.28 v.26 + add file load and save convenience buttons to job edit dialog + increase file limit from 100K to 200K files (memory usage +15 MB) 2007.05.13 v.25 + replace menu and toolbar macros with new zfuncs functions 2007.04.25 v.24 + minor report improvements + add report: disk:DVD differences by directory + allow file size exceeding 2 GB 2007.04.08 v.23 + fix bug: thorough verify was checking files created after last DVD update + progress monitoring: backup displays file names being written to DVD + set margin for comparing file mod times to 1 ms instead of 1 sec. + remove new owner option from restore (don't duplicate Linux capability) + use c-lib functions for file restores instead of shell commands 2007.03.26 v.22 + detect mount EROFS status (read-only file system) and call it success 2007.03.26 v.21 + unmount DVD before eject (avoid drive hung busy with some Linux kernels) + use $ wodim -abort to reset hung-up DVD drives (newer Linux systems only) 2007.03.19 v.20 + clarify output from menu: DVD and mount point + use mount() function for DVD instead of shell - better status information 2007.02.02 v.19 + job editor: select DVD and mount point from list (instead of typing in) + incremental backup: eliminate duplicate differences report 2007.01.10 v.18 + use generic monospace font instead of Courier 10 (not always available) + rationalized menus and toolbar buttons for more conventional interface + removed Joliet file system from DVD: Windows XP can read standard DVD + converted dialogs to zdialog functions + added icons to toolbar buttons 2006.11.30 v.17 + added tool tips to buttons 2006.11.28 v.16 + added 3 sec. delay between backup and verify and between mount retries (DVD drive may still be busy after growisofs completes, causing following mount command to fail) (why is the driver so flakey?) + reorganized library functions into zfuncs.cpp and zfuncs.h + added "edit" button for faster access to backup job editor + corrected bug causing verify error for file names with trailing blanks 2006.11.01 v.15 + added menu: set DVD device and mount point independently of job file. + bug fix: report of disk-DVD differences was ignoring a manual DVD change. + GTK 2.6.10 issue: hidden files not shown in the file-chooser dialog.

Download the tar file (dkopp-N.N.tar.gz) to Desktop 2. Open a terminal window 3. $ cd Desktop # go to Desktop 4. $ tar -xzf dkopp-N.N.tar.gz # unpack to ./dkopp 5. $ cd dkopp # go there 6. $ make # build program 7. $ sudo make install # install program Missing dependencies will cause error messages in step 6. Install these from your repository and repeat step 6. Step 7 moves all files to the following locations: /usr/bin/dkopp binary executable /usr/share/dkopp/ icons, translations ... /usr/share/doc/dkopp/ user guide, README ... For step 7, use "sudo" or "su -c" to get root privileges. To run dkopp, the programs growisofs and either mkisofs or genisoimage are needed. These are normally included in Linux distributions. If needed, use your package manager to install them. The program wodim is also recommended (currently used only to reset a hung DVD drive). Normally dkopp is run as root so that DVDs can be mounted. Use "sudo dkopp" or "gksu dkopp". Please review the user guide (Help menu) before trying dkopp. NOTES FOR PACKAGE BUILDERS: If $PREFIX is defined, files go there instead of /usr. If $DESTDIR is also defined, files go to $DESTDIR$PREFIX. dkopp-6.5/doc/dkopp.man0000644000175000017500000000424712343020444013523 0ustar micomico.TH DKOPP 1 2010-10-01 "Linux" "Dkopp man page" .SH NAME Dkopp - copy files to DVD or BD (Blue-ray) media .SH SYNOPSIS \fBdkopp\fR [ \fB-job\fR | \fB-run\fR ] \fIjobfile\fR \fBdkopp\fR [ \fB-nogui\fR ] \fB-script\fR \fIscriptfile\fR .SH DESCRIPTION Dkopp copies files to backup DVD or BD media. It supports full or incremental backups and full or incremental media verification. .SH OVERVIEW Dkopp is a menu-driven GUI (GTK) program operating in its own window. Dkopp copies files and directories specified in a job file to DVD or BD media. Dkopp can copy all files to empty media (full copy), or only new and modified files to previously used media (incremental). Files and directories to include or exclude can be selected from the file system hierarchy using a GUI navigator. Specifications are saved in a job file which can be re-edited and re-used. Script files can be run in batch mode using the \-nogui option. Dkopp can be used to select and restore files previously copied, and owner and permission data is also restored. The DVD/BD media can also be accessed with file system tools like Nautilus. Dkopp supports the following functionalities: - Three backup modes: full, incremental, accumulate. - Three media verification modes: full, incremental, thorough. - Use write-once or re-writable DVD or BD media (but not CD). - Report disk:backup differences in detail or summary form. - Select and restore files from a backup copy (or use drag and drop). - Search log files to find media where specified files are saved. .SH OPTIONS Command line options: [ \fB-job\fR ] \fIjobfile\fR open job file for editing \fB-run\fR \fIjobfile\fR execute a job file [ \fB-nogui\fR ] \fB-script\fR \fIscriptfile\fR execute a script file .SH SEE ALSO The online user manual is available using the menu Help > contents. This manual explains Dkopp operation in great detail. Dkopp uses the batch programs \fBgrwoisofs\fR and \fBgenisoimage\fR. Dkopp is essentially a GUI front-end for these programs. .SH AUTHORS Written by Mike Cornelison dkopp-6.5/doc/copyright0000644000175000017500000000100012343020444013624 0ustar micomicoAuthor: Michael Cornelison Copyright: Copyright 2007-2014 Michael Cornelison The source program code can be found here: http://kornelix.com/tarballs License: You are free to distribute this software under the terms of the GNU General Public Licensel, either version 3 of the License, or (at your option) any later version.

Dkopp Introduction
Dkopp is a Linux utility program for copying files to recordable DVD or Blue-ray disk (BD). Dkopp is a free open source program licensed under the GNU General Public License v.3.

Three kinds of backup are available: full, incremental, and accumulate. A full backup copies all specified files and leaves no other files on the DVD/BD. An incremental backup adds only new or modified files to a prior dkopp copy, bringing it up to date. This is normally much faster than a full backup. Unmatched files on the DVD/BD are also deleted, so that the DVD/BD is left exacty matching the source files. An accumulate backup is like an incremental backup, but unmatched files are not deleted.

You select files to be copied using a GUI. You can navigate through the file system and select files or directories to include or exclude at any level in the hierarchy. These choices can be saved in a job file to automate recurring backups. If files are added or deleted within an included or excluded directory, the next dkopp run will include these changes automatically.

DVD/BDs can be verified three ways: full, incremental, and thorough. A full verify reads the entire DVD/BD and reports any files having read errors. An incremental verify reads only those files that have been newly written by a preceding incremental backup. This is usually much faster while still offering a high level of security. A thorough verify reads every file on the DVD/BD and makes a bytewise comparison with the corresponding disk files. This is normally unnecessary, but it provides an additional assurance that hardware and software are working correctly.

You can list all files in a backup job, or all files on a DVD/BD. You can search for specific files using wildcards. You can compare a DVD/BD with the corresponding backup job, listing all differences: files that have been created, deleted, or modified since the DVD/BD copy was made. This comparison can be done at three levels: a detailed list of files, a directory level summary, or a job level summary.

For disaster recovery or file transfer, dkopp has a file restore capability. You can select and restore DVD/BD files to their original directories or anywhere else.

An incremental backup updates a DVD/BD made with a prior full backup. This simplifies both backup and restore: you do not need to track full and incremental backup media, and you do not need to restore files from multiple media in correct sequence.

Searchable log files are generated with time/date, DVD/BD label, and files copied. You can search the log to find all DVD/BDs with copies of a desired file, using wildcards to simplify the search (e.g. find  */joeblow/*/planB* ).

A script file can be used to automate backups or run dkopp from a shell script. The GUI is not used in this case.

Incremental backup and verify can take less than a minute if the updated files are within 30 megabytes or so. For larger jobs, the DVD/BD speed determines the time required. With 4x DVD media, backup + verify runs about 150 megabytes per minute.

Dkopp is a graphical front end for the command-line programs growisofs and genisoimage. The added functionality is ease of use, espicially the easy way to specify the files to be copied.



Dkopp Concepts
The files in a backup job are specified with include and exclude statements. These have filespecs with optional wildcards placed almost anywhere. Examples:
   include /home/*                  # add user files
   include /root/*                  # add root files
   include /shared/*/documents/*    # add shared document files
   exclude */mp3/*                  # exclude files in mp3 directories
   exclude */.Trash/*               # exclude trash files

The first include adds all files owned by users in their home directories and sub-directories. The second include adds all files owned by root. The third include adds all files under the /shared  top directory that also have an intermediate directory named /documents. The two exclude statements exclude files within  /.Trash  and  /mp3  directories at any level.

GUI interface: The above statements are normally generated using a standard Gnome file selection dialog. The process is documented in the section on editing backup jobs.

file selection logic:
   loop:
       get next control statement. If no more, done.
       if include: add all matching files to backup file set.
       if exclude: remove all matching files from backup file set.
   loop-end

Note that excludes are effective only against prior includes. They have no effect on following includes, which are processed afterwards. See the section on editing backup jobs.

Restriction: include statements must include at least the first directory name (top-level) without wildcards (the GUI file-chooser does this automatically).

limitations:
    + max. 200,000 files in a backup job (compile time constant)
    + dkopp runs as root user (password is requested if not already root user)
    + supports DVD/BD media only (not CD media)
    + not useful for disk imaging (operating system backup)

After installing dkopp, please perform the first tryout exercise (below). This may be all you need at first (if you are like most people and RTFM is a bore). You can enhance your security and ultimately save time if you read this whole document.

Dkopp first tryout
The following short exercise will check that dkopp functions correctly on your system and help you become familiar with dkopp usage.

  1. Load a recordable DVD/BD and wait for the desktop icon to show up.

  2. Start dkopp (use the system menu or a terminal command: $ dkopp).
    Start as root user ($ sudo dkopp). If not, dkopp will request root user by itself.

  3. Select button: [ edit job ]

  4. Set the DVD/BD device ID (choose from list of available devices if more than one)

  5. Select full backup and full verify

  6. Erase the default backup job shown (select and delete, or use the  [ clear ]  button)

  7. Select the button  [ file chooser ]  at the bottom

  8. Navigate through the directories and select some files or directories to be copied
    + double-click a directory to open it and enable selection within that directory
    + select one or more files/directories, using left-mouse (or shift+left-mouse)
    + use the  [ include ]  button to include all selected items in the backup job
    + use the  [ exclude ]  button to exclude items previously included at a higher level
    + use the  [ include ]  button to include items previously excluded at a higher level
    + use the buttons at the top to go back up the directory hierarchy
    + use the  [ hidden ]  button to toggle the display of hidden files

  9. Select the  [ done ]  button when finished selecting files

  10. Inspect the generated include and exclude statements. These may be edited directly if desired (e.g. erase mistakes or redundancies, change the order, or make additions or revisions). Re-enter the file chooser dialog if wanted - new choices will be appended. Cycle between the editor and file chooser as much as needed

  11. Select button  [ OK ]  when done editing the job

  12. If errors are shown, select  [ edit job ]  and fix. Remember that exclude statements must follow relevant include statements - excludes are exceptions to prior includes, and includes may be exceptions to prior excludes.

  13. Select menu: Report > get backup files. Inspect the counts. Be sure the total byte count is within the DVD/BD capacity. Look for zero counts, indicating possible errors. Re-edit the job if needed.

  14. Select button: [ run job ]. The backup should begin.

  15. Verification should follow automatically. You will be asked to re-mount the DVD/BD.
    Check that the error count is zero when finished.

  16. Save the job file if desired: menu: File > save job

  17. Select button: [ quit ]  

  18. Next steps: play with incremental backups and reports




File Menu

open job

Open a previously saved backup job file for re-use (edit, run).
The default location for job files is /home/user/.dkopp (or /root/.dkopp).

open DVD/BD
Open the backup job file on the currently loaded DVD/BD.
This file was saved on the DVD/BD when the last backup job was run on that DVD/BD.

edit job
Opens an edit dialog for the current backup job (from the last job file opened, or from a prior edit).
If no file has been opened, internal default data will be used as a starting point.

show job
List the current backup job data and diagnose any errors.

save job
Save the current backup specifications in a job file.
Default is the same file that was last opened, but you may select any file.

run job
The current backup job is executed. Backup and verify modes are taken from the job.
Be sure to read the technical notes about DVD/BD mounting.

run DVD/BD
The backup job file stored on the DVD/BD is executed. Backup and verify modes are taken from the DVD/BD job. Whenever a backup is performed, the current job file (including any edits that were made) is copied to the DVD/BD.

Note: what is copied to the DVD/BD is the current job, not menu commands given manually. Thus, if you load a job file which specifies incremental backup, and then do a full backup using the menu command, the backup job stored on the DVD/BD will still specify incremental. To change the job written to the DVD/BD, edit the job before starting the backup.

quit
Exit program.



Backup Menu

full
The current backup file set is copied to the DVD/BD fully. All files are copied unconditionally. The DVD/BD is initialized to an empty status. For large jobs, additional DVD/BDs will be requested as needed. If growisofs aborts the job (declaring the DVD/BD to be "unknown type" or "not formatted"), the menu command  DVD/BD > format  may fix the problem. Be sure to read the technical notes about DVD/BD mounting.

Incremental
The current backup file set is copied to DVD/BD incrementally. New and modified files (since the DVD/BD was created or updated) are copied. Files that already match their corresponding disk files are not copied. Any "extra" DVD/BD files (not in the backup file set) are deleted. At the end, the DVD/BD is 100% identical to the backup file set, with the possible exception of files modified during the backup run. See the technical notes for more details about how matching files are recognized and skipped over.

accumulate
Same as incremental, but without DVD/BD file deletions.



Verify menu

full
All files on the DVD/BD are read and checked for errors. DVD/BDs need this extra level of protection, since poor media quality has been a problem. If errors are detected, clean off the fingerprints or discard the DVD/BD. If errors happen on more than 1% of your media, consider getting a new drive or changing media brands. Note that any CD or DVD or BD can be "full" verified - it does not have to be a dkopp backup disk.

incremental
New files on the DVD/BD are read and checked for errors. "New" means any files written by an immediately prior incremental or accumulate backup. Files not written are not checked.

thorough
All DVD/BD files are read and verified that there are no read errors. Those DVD/BD files that have a matching disk file (matching full path name and modification date/time) are bytewise compared to the disk file, and any files not matching are reported. There should be no differences. This verifies that all hardware and software (driver, file system, dkopp) are working correctly. DVD/BD files that are expected to be different (different mod times) are read and checked for errors, but not compared with the disk. Dkopp considers two files to have the same mod times if they differ by less than one second (the time resolution for files on DVD/BD media).

The following counts are reported at the end of the verify job:
     + total DVD/BD files and bytes
     + DVD/BD files having read errors (should be zero)
     + DVD/BD files having matching disk files (by name)
     + DVD/BD files having matching disk files (by name and mod time)
     + for the last category, the number of DVD/BD:disk compare errors (should be zero)



Report menu

get files for backup
The backup job include and exclude statements are listed, along with the file and byte counts that are added or removed by each statement. Look for zero counts, indicating a possible error. The disk directories are read and the list of files included in the backup job is saved in memory. This data is used to determine what files are different between the disk and DVD/BD and must be copied for an incremental backup. The file list is static and is not updated by disk activity. The list of "new" files that are checked with an incremental verify is also reset with this command.

diffs summary
Report the total number of files in each category:
   new             on disk, but not on the DVD/BD
   modified        on both, but not the same content
   deleted         on the DVD/BD, but not on disk
   unchanged       on both, with the same content
Differences between the disk and DVD/BD may be caused by disk updates (file additions, deletions, updates, or moves), or by changes to the job file itself.

diffs by directory
Each directory having differences between the disk and DVD/BD is reported, along with counts of new, modified, and deleted files. The total bytes for new and modified files is also given.

diffs by file
All files that are different between the disk and DVD/BD are listed in alphabetic sequence within groups for new, modified, and deleted files.

list files for backup
All files in the backup file set are listed in alphabetic sequence. Use this to check that the correct files are being backed-up.

list DVD/BD files
All files on the DVD/BD are listed in alphabetic sequence.

find files
Enter a search pattern with optional wildcards (e.g. /home/dir*name/file*name).  All matching file names on the disk (in the backup job file set) are listed. All matching file names on the DVD/BD are listed. All backup log files are also searched, and those containing the target file(s) are listed (by date / time and DVD/BD label). These files correspond to backup jobs, one-to-one. Use this method to locate all backup copies of a given file or group of files, sorted from oldest to newest. A file may be present in multiple log files for multiple incremental backups made to the same baseline full backup, but it actually exists only once on the DVD/BD, in its latest version.

view backup hist
All backup history log files are listed (up to 200). These correspond to backup jobs, one-to-one, and contain a list of files copied to the corresponding DVD/BD. The most recent 20 log files are put into a dialog for selection. Select one of these from the dropdown list, or modify the input to select an older file. The text editor gedit is invoked to display the log file. You can page up and down and search for strings using gedit.

Backup log file names are formatted as follows:  dkopp-hist-yyyymmdd-hhmm-label
Note that one DVD/BD having a full backup and one or more incremental backups will have a log file for each backup, showing those files copied for each backup. A file may be present in multiple log files for multiple incremental backups made to the same baseline full backup, but it actually exists only once on the DVD/BD, in its latest version.

save screen
The main window, where messages and reports are written, is saved in an ordinary text file.



Restore menu

setup DVD/BD restore
Specify the copy-from location (on the DVD/BD), the copy-to location (on disk), and the files to be restored. The copy-from location is the topmost DVD/BD directory of a tree of files to be restored.
  example:  /home/joeblow/documents    # note that mount point is omitted
The copy-to location is an existing disk directory where the tree of files will be copied-to.
  example 1:  /home/joeblow/documents
  example 2:  /home/joeblow/documents/restored
In example 1, the restored files will go back to the same place they were when backed-up. In example 2, they will go to a new place.

Files to be restored are specified the same way as in a backup job (see the section below on using the file selection dialog). Use the button  [ file chooser ]  to start the dialog.

If you need to restore multiple trees of files, you can do this in multiple runs, or you can simply begin the tree at a higher level and use the file selection dialog to specify multiple sub-trees.

list restore files
After performing the setup, use this function to list all matching files on the DVD/BD that will be restored, exactly where they will be restored. You should check this list carefully to be sure you are restoring the correct files to the intended locations.

restore files
When you are satisfied with the restore job specification, use this menu to perform the restore. You will see a running log of the activity. Use the kill button to stop the job if desired.



DVD/BD menu

set DVD/BD device
The DVD/BD device and mount point may be set independently of the backup job. The DVD/BD device and mount point for the current backup job is modified. No mounting is done.

set DVD/BD label
Set the DVD/BD label that will be used for a subsequent backup job. The default is to keep the same label that the DVD/BD already has. The DVD/BD mount command will show this label. If no label is assigned, "dkopp" is used.

mount DVD/BD
Mount a DVD/BD. You are asked to insert a DVD/BD and wait for the mount to complete. If the mounted DVD/BD has been used for dkopp before, the date-time of the last backup to this DVD/BD is displayed. Be sure to read the technical notes about DVD/BD mounting.

eject DVD/BD
The DVD/BD is unmounted and ejected.

reset DVD/BD
This does a hardware reset to the DVD/BD drive. This is sometimes useful if a drive gets locked-up and cannot be ejected using either the dkopp eject command or the tray button. This sometimes happens when there is a DVD/BD error or a backup is killed in mid-process. This may or may not work. If the DVD/BD drive remains hung after several minutes, the only resort is a reboot.

erase DVD/BD
Writes zeros to the entire DVD/BD surface. This takes 10+ minutes, depending on the DVD/BD drive speed and medium. This works only for rewritable media (DVD+RW or DVD-RW or BD-RE). DVD-R and BD-R media are write-once and cannot be erased. See the technical notes below for more about privacy and data protection.

format DVD/BD
This uses the dvd+rw-format utility to format a disk in a few minutes. The entire DVD/BD is not erased. See the technical notes below for more about privacy and data protection. If Backup > full refuses to start, this format command may fix the problem.



Help menu

contents
Display the help file (this file).

about
Display the dkopp program version and date.



Toolbar buttons

root
This button restarts dkopp with root privileges if your password (sudo) is correct.

edit job
Shortcut to the backup job editor (same as menu File > edit job)

run job  and  run DVD/BD
The current job, or the job on the DVD/BD, is executed.
Be sure to read the technical notes about DVD/BD mounting.

pause  and  resume
The currently running job or menu function may be paused and resumed.
Use this to inspect output on the fly.

kill job
The currently running function is killed. You may need to wait a while for the function to die and screen output to cease. If a backup job is killed, growisofs will gracefully exit in a few seconds, leaving the DVD/BD in an undetermined status.

clear
The main window, where messages and reports are written, is cleared.

quit
Exit the application. If the job file has been edited and not saved, you will be given an opportunity to save the changes.




Editing backup jobs (see screenshot below)

Select menu: File > edit job  or button: edit job

Fill-in the following items in the dialog box:
  DVD/BD device    /dev/sr0
  capacity GB      4.0
  write speed      4  (x 1.38 MB/sec)
  backup mode      check full / incremental / accumulate
  verify mode      check full / incremental / thorough
  file date from   leave default (1970.01.01) or input a later date

Select the DVD/BD device from the drop-down list of available devices. The DVD/BD capacity may be set from 1.0 to 50 GB (for double layer Blue-ray media). Full backups will be limited to this amount. The default of 4.0 GB leaves a leftover space of about 0.7 GB for incremental updates. See the technical notes for more details about this. Write speed is the speed factor to use for writing the DVD/BD medium. This is the "2x" or "4x" rating shown on the DVD/BD. Leave this blank or zero to use the default speed. You may select a lower speed than the default if needed to increase reliability (i.e. if the verify function reports errors). I have never needed this, but others have reported that some media and drive combinations are not reliable at the rated speed. "file date from" is an additional method for selecting files to copy. Files with a create or modification date older than this will be ignored.

File selection dialog
You may edit the backup file set (the include and exclude statements) directly in the text window. You may also use the [browse] button to get a standard file selection dialog, with additional buttons: hidden, include, exclude. The [hidden] button toggles the display of hidden files (file names with leading dots, like .gnome). Select one or more directories or files, using left-mouse or shift+left-mouse, then press the [include] or [exclude] button. The selected files/directories will be written into the text window as include or exclude statements. If you select a directory, the entry is modified to add a wildcard at the next level:
       selecting directory  /aaa/bbb/ccc   →   include /aaa/bbb/ccc/*

You may alternate between editing the text window and using the file-chooser dialog. When you are done, press [done] to accept. The include/exclude data will be validated to the extent possible. Go back and re-edit to fix any problems. To change the sequence, cut and paste in the text window. When you are done, use the report functions "get backup files" and "list backup files" to  verify that you have the correct files!

The include and exclude control statements allow precise control of the backup file set:
  include /aaa/bbb/*             # include file tree under /aaa/bbb/
  exclude /aaa/bbb/ccc/*         # exception: exclude /ccc/ subtree
  include /aaa/bbb/ccc/xxx.yyy   # exception: include file /ccc/xxx.yyy
The file-chooser dialog may be used to quickly converge on the desired results. The editor may also be used to make adjustments.

Because of wildcards, newly added files within the scope of existing include or exclude filespecs are automatically comprehended. In the above example, if a new file is added somewhere within the /aaa/bbb/ tree, it will be automatically included in the next backup job, unless of course it is in the excluded  /aaa/bbb/ccc/  subtree.

The  file > edit job  menu command (or toolbar button) pops up the middle box. This can be edited directly: click anywhere in the text area and start writing. The right box is the choose files dialog, which is started with the [browse] button. Choose files using the right box, and the middle box records your choices. You can navigate around the directory hierarchy and select any number of files or directories. The [hidden] button toggles the display of hidden files. Click the [include] or [exclude] button to get the selected files added to or removed from the backup list. Selecting a directory is an implied selection of all contained files, thus the selection appears as  directory/*  in the list of selected files. To make an exception, go down one level, choose files, and select the opposite [include] or [exclude] button. You can refine the file selections manually if desired. It is sometimes handy to use wildcards in the directories to make more general and compact selection criteria, e.g. 
   exclude *thunderbird*/Trash* 
will omit trashed mail even if the overlying directories change (they do) and even for multiple users (the leading wildcard includes "/home/*").

You can add comments, or disable an include / exclude line, by putting  #  in column 1.



Script Files

A script is a text file with a series of commands that can be run as a batch job. All dkopp menu commands can be scripted.

The format of the records in the script file is as follows:
   menu1 > menu2 > parameter    # comment
The menu names must match the interactive menu names exactly, including case.

To run a script file:   $ dkopp -script /pathname/scriptfile

You can also add the option  -nogui  for deferred execution. Dkopp will not create a window or ask for any inputs in this mode. You must leave a DVD/BD in the drive for dkopp to use later.

Here is a sample script file to get you familiar with the possibilities:
   File > open job > jobfile1
   Report > get backup files
   DVD/BD > mount DVD/BD
   Report > differences-detail        # report changed files
   Backup > incremental               # back them up
   Verify > full                      # verify all files
   Report > differences-counts        # should be zero
   File > save screen > dkopp.log     # save a log file
   DVD/BD > eject DVD/BD
   File > quit

The toolbar buttons may also be used, e.g.  
     button > pause    # press resume to continue
At this point you may use the menu interactively and then resume the script by pressing the resume button.

The command  exit  may be used to end the script file and return to interactive mode.
Script file EOF does the same thing.



Large Backup Jobs (more than one DVD/BD)

A full backup may be larger than one DVD/BD, and you will be asked to load additional DVD/BDs as needed. If a job is being run (rather than the menu backup > full) each DVD/BD will be verified (if specified in the job) before the next DVD/BD is requested. An attempt is made to fit all files derived from a single include  statement on the same DVD/BD, if possible. This allocation is made after excluded files have been removed from the backup file set. The job file written to each DVD/BD reflects the files actually copied to that DVD/BD, so that subsequent incremental updates may be done individually on each DVD/BD, e.g. as follows:
     File > open DVD/BD
     Backup > incremental
     Verify > incremental
Note that if an include statement is too big to fit on one DVD/BD, this strategy will not work as expected. The backup job file on the first DVD/BD will have the big include statement, but additional DVD/BDs used for this same include will not. If possible, break up the large include statement into smaller ones.



Technical Notes

Mounting DVD/BD media: Starting with v.6.4, dkopp no longer mounts DVD/BD disc itself, but outputs a popup message asking the user to do this. Insert the disc, wait for the desktop icon to show up, and then press the [OK] button in the popup dialog. The appearance of the desktop icon may or may not mean that the disc is actually mounted (this varies in the systems I test with). If dkopp responds with "waiting for mount ...", click the desktop icon to encourage the window manager to mount the disc. This change was made to relieve dkopp of the need to understand what Gnome and other window managers do about DVD/BD disc mounting.

DVD mount errors and growisofs errors: There are many of these, and they change with each new release of the kernel, Gnome, and growisofs (the command-line program used to write the DVD/BD). Often they are bogus errors that are not really errors, or they are temporary errors that will go away when the operation is tried again. Dkopp is unable to distinguish the difference. In the case of a full backup, the user is given a popup dialog with the options to abort the job, retry the full backup, or ignore the error and continue. If the backup job did not even get started, use retry. If the backup job seems to have completed, use ignore. Verify will detect later if any error actually happened.

Blank DVD/BDs: the first time a DVD/BD is used, do a full backup. A blank DVD/BD will not mount, but a full backup will still work and make the DVD/BD mountable thereafter.

Flakey DVD/BDs: drive and media combinations sometimes have compatibility problems, resulting in media errors. The newest drives (2006 and later) are much better at adjusting to media variations. I have had a few DVDs (<1%) that passed a dkopp verify and then became unreadable later, so make regular backups and avoid depending on a single DVD/BD.

Media errors: If the dkopp verify function runs into a read error, the DVD/BD drive may lock-up for a minute or more while retrying the failed read hundreds of times. Give the "kill" command and wait for the drive to give up. If the DVD/BD is dirty, clean it and try again. Otherwise throw it out.

Privacy and data protection: to protect your private data on discarded DVD/BDs, you should destroy them. A few seconds in a microwave oven will completely destroy the metallic recording layer (with spectacular visual effects). Do not inhale the fumes.

Command line arguments:
  $ dkopp -job jobfile                    # load job file
  $ dkopp  jobfile                        # load job file
  $ dkopp -run jobfile                    # load job file and run it
  $ dkopp -script scriptfile              # run script file
  $ dkopp -nogui -run jobfile             # run job in non-GUI mode
 
The -run and -script commands are intended for shell scripts. The -job command is more useful for a desktop launcher, leaving the user free to elect the backup mode or make other changes in the job before execution. If the jobfile name contains blanks, quotes are required, e.g.
    $ dkopp -job "my dkopp job"

The -nogui option will prevent dkopp from opening a window or asking for any interactive inputs. Use this for deferred operation (batch job). You must leave a DVD/BD in the drive for dkopp/growisofs to use.

Deleted DVD/BD files: growisofs is used to perform the file copies. It can replace existing DVD/BD files with new versions, but it does not delete files. For incremental backups, dkopp replaces deleted files with null files (zero length). Full backups do not have this issue, since the DVD/BD is initialized. If you recover files from a dkopp DVD/BD using a shell copy command with wildcards, or Nautilus drag-and-drop of an entire directory, you may get unwanted null files. If this happens, it is easy to get rid of them like this:
      $ rm -i $(find /dir1/.../dirN -empty)
(remove all empty files in a directory tree, with confirmation of each)
Note that if you use dkopp restore, these null files are invisible and are not restored.

Incremental backups: a DVD/BD file is considered identical to its corresponding disk file if their lengths and modification times are the same. Incremental backups exclude such files. If the modification times differ by less than 1 second they are considered equal (another way to look at this issue: file backup times may be wrong by up to 1 second). A thorough verify will read and compare the files unconditionally. File mod times on DVD/BD media have a 1 second resolution.

File names containing "=":  genisoimage requires that "=" in file names be replaced with "\=". The file-chooser dialog in dkopp file restore shows "\=" instead of "=", but the files will be correctly restored with "=" only.

Restoring file owner and permissions: The file system used for DVD/BD media does not support file owner and permissions, so dkopp writes a special file to the DVD/BD with this data. Restored files have original owner and permissions.

Special dkopp files on DVD/BD:
Directory /dkopp-data is written to the DVD/BD with three files:
     datetime        backup date-time and DVD/BD usage count
     filepoop         owner and permissions for all backed-up files and directories
     jobfile            a copy of the backup job specs last used on this DVD/BD
These are ordinary text files which you can view with an editor.

Special file types: pipes, devices, and sockets are not copied. Symlinks are copied as such. Both symlinks and their targets should be included in the backup or restore file set, since it makes no sense to copy one without the other. This normally happens by default, since symlinks typically link to files in the same directory. Symlinks are used commonly in system directories and in the hidden system files within a /home/user directory. For user files, there is no need for them.

Killing growisofs (killing a backup job in progress): this will sometimes leave the DVD/BD in a condition that growisofs refuses to deal with. If you decide to abort a backup job (e.g. to revise the job specs and start over), you may get this condition. You should retry a full backup on this DVD/BD. If growisofs still refuses, format the DVD/BD (dkopp menu), then try the full backup job again.

Duplicate files: If job file "include" statements overlap, resulting in duplicate files in the backup set, this is reported and the backup is terminated.

Microsoft Windows: DVD/BDs created with dkopp use the standard ISO-9660 file system, which can be read by Windows.

DVD/BD drive and media information: here are two useful commands:
  $ udevinfo -q all -n /dev/dvd      # DVD/BD drive information
  $ dvd+rw-mediainfo /dev/dvd        # DVD/BD media information

Incremental backups: new and updated files are written to a new "session" on the DVD/BD, along with new directory files which may reference data files in both the old and new sessions. Nothing is changed in the old sessions. Thus, incremental backups consume more space on the DVD/BD even if the corresponding disk files are not any bigger. For DVD+R, DVD-R and BD-R media (write once), only one full backup may be made, and as many incremental backups as can fit in the remaining space. For DVD+RW, DVD-RW and BD-RE media (rewritable), a new full backup will initialize the DVD/BD and recover all space. These DVD/BDs can be used until they wear out. I have exceeded 100 uses on a test DVD+RW medium and it still works fine.

Growisofs progress tracking: Growisofs (genisoimage) outputs a "% done" value every few megabytes. Dkopp uses this number to compute the current position in the list of files to be copied, and the resulting file is echoed to the main window. The update frequency is typically less than once per file, so some file names will be bypassed. Large files may stay on the screen for several update cycles. For full backups, the math is straightforward. For incremental backups, growisofs starts off with:
       % done = 100 * (initial DVD/BD bytes used) / (final DVD/BD bytes used)
Dkopp assigns this value to the first file in the backup list. The last file is assigned 100%, and the rest are interpolated using accumulated bytes.

Linux error codes: Linux error codes can be misleading. If an attempt is made to open a file that is already open and therefore locked, the error code translates to "no such file or directory". The error codes are the same for an attempt to mount an empty tray or a corrupted DVD/BD. The same is true for an attempt to mount a DVD/BD that is already mounted, or a blank DVD/BD. Dkopp outputs messages of its own that mention the multiple possibilities. Hopefully this will improve over time.

Backup history files: A history file is generated for every backup job run.
     location:      /home/username/.dkopp/   (or)   /root/.dkopp/  
     file name:    dkopp-hist-yyyymmdd-hhmm-label
The file name corresponds to the date and time of the backup and the DVD/BD label. A history file contains a list of all the files copied to that DVD/BD at that time. Thus, a DVD/BD used for a full backup and two incremental backups will have three corresponding history files, each one containing those files copied by the respective backup job. A full backup spanning multiple DVD/BDs will have multiple history files, one per DVD/BD. History files accumulate and are not automatically deleted. When 200 files are reached, the find files and view backup history reports produce warnings. Delete the oldest files or move them elsewhere. The 200 limit is a compile time constant: maxhist. This could be set much higher if desired (and if you have so many DVD/BDs before you re-use them).

DVD/BD label: The menu  DVD/BD > set DVD/BD label  is for an optional DVD/BD label input, which you can use as part of your media management system. A subsequent backup job will write this label to the DVD/BD, and the DVD/BD mount command will show the label. Recommendation: for full backups, set the label to match what is written on the DVD/BD (with a soft pen). For incremental backups, leave the label unchanged.

genisoimage errors: If a disk file is deleted after growisofs begins, the DVD/BD will be defective: directory entries for the missing files and all following files will point to garbage (which may even be readable). The error reported by genisoimage is ignored by growisofs. Dkopp scans growisofs output for the ignored errors and un-ignores them.

DVD/BD media types:
   DVD+RW      good for many (hundreds?) of full and incremental backups
   DVD-RW      good for many (hundreds?) of full and incremental backups
   DVD+R       good for one full and many incremental backups
   DVD-R       good for one full and many incremental backups
   DVD-RAM     good for many (thousands?) of full and incremental backups
               (perportedly the most reliable media)
   BD-R        good for one full and many incremental backups
   BD-RE       good for many (?) full and incremental backups

This may be zero because of the long interval between timer updates. Accuracy comes from statistical sampling over many seconds, so that if the time spent in a monitored function is significant, it will be accounted for. The accuracy is better than 1% as long as the measured function or code block consumes a second or more of CPU time during the measurement period. The "fnum" argument (1-99) designates the function or code block being measured. cpu_profile_report() stops the timer thread and reports time consumed per function, using the "fnum" tags in the report. The functions cpu_profile_enter() and cpu_profile_exit() subtract the timer difference and add to a counter per fnum, so the added overhead is insignificant. They are inline functions defined as follows: enter: cpu_profile_timer = cpu_profile_elapsed; exit: cpu_profile_table[fnum] += cpu_profile_elapsed - cpu_profile_timer; ***************************************************************************/ volatile double cpu_profile_table[100]; volatile double cpu_profile_timer; volatile double cpu_profile_elapsed; volatile int cpu_profile_kill = 0; void cpu_profile_init() { void * cpu_profile_timekeeper(void *); for (int ii = 0; ii < 99; ii++) cpu_profile_table[ii] = 0; cpu_profile_elapsed = 0; start_detached_thread(cpu_profile_timekeeper,null); } void cpu_profile_report() { cpu_profile_kill++; printz("elapsed: %.2f \n",cpu_profile_elapsed); for (int ii = 0; ii < 100; ii++) { double dtime = cpu_profile_table[ii]; if (dtime) printz("cpu profile func: %d time: %.2f \n",ii,dtime); } } void * cpu_profile_timekeeper(void *) { timeval time0, time1; gettimeofday(&time0,0); while (true) { gettimeofday(&time1,0); cpu_profile_elapsed = time1.tv_sec - time0.tv_sec + 0.000001 * (time1.tv_usec - time0.tv_usec); zsleep(0.001); if (cpu_profile_kill) break; } cpu_profile_kill = 0; pthread_exit(0); } /**************************************************************************/ // Returns hard page fault rate in faults/second. // First call starts a thread that runs every 2 seconds and keeps a // weighted average of hard fault rate for the last few intervals. namespace pagefaultrate_names { int ftf = 1; int samples = 0; int faultrate = 0; double time1, time2; void * threadfunc(void *); } int pagefaultrate() // v.5.8 { using namespace pagefaultrate_names; if (ftf) { ftf = 0; start_detached_thread(threadfunc,0); time1 = get_seconds(); } return faultrate; } void * pagefaultrate_names::threadfunc(void *) { using namespace pagefaultrate_names; FILE *fid; char *pp, buff[200]; double pfs1, pfs2, fps, elaps; while (true) { sleep(2); time2 = get_seconds(); elaps = time2 - time1; time1 = time2; fid = fopen("/proc/self/stat","r"); if (! fid) break; pp = fgets(buff,200,fid); fclose(fid); if (! pp) break; pp = strchr(pp,')'); // closing ')' after (short) filename if (pp) parseprocrec(pp+1,10,&pfs1,11,&pfs2,null); fps = (pfs1 + pfs2) / elaps; faultrate = 0.7 * faultrate + 0.3 * fps; } printz("pagefaultrate() failure \n"); pthread_exit(0); } /************************************************************************** strField() cchar * strField(cchar *string, cchar *delim, int Nth) Get the Nth field in input string, which contains at least N fields delimited by the character(s) in delim (e.g. blank, comma).

A field with only blanks is returned as a single blank. The last field may be terminated by null or a delimiter.

However the .po files are used directly, and there is no need to merge and compile them into a binary format (.mo files). A translation file is one of: /translate-lc.po or *-lc_RC.po where "lc" is a standard language code and "lc_RC" a language and region code. The file may also be compressed with the file type .po.gz Translation files contain two record types: msgid "english text" msgstr "translation text" The text strings may continue on multiple lines, each such segment enclosed in quotes. The strings may contain C-format codes (%s %d etc.) and may contain escaped special characters (\n \" etc.). A text string may have a context part "context::string", where "context" is any short string, "::" is a separator, and "string" is the string to translate or the translation of a string. This is to handle the case where a single English string may need multiple translations, depending on context. The English string may be present multiple times in a .po file, each one marked with a different context and having a different translation. The context part is optional in the translation strings and is not displayed in the GUI. Initialize translations: int ZTXinit(cchar *lang) lang is "lc" or "lc_RC" or null (current locale will be used) Initializes the running application for the translation of text message strings for non-English locales. It reads a translation file which matches the English text strings in the source program to translated text strings for the user's locale. This file is uncompressed if necessary and copied into the user's files at /locales/translate-lc.po. This is done only if the file at is newer than the copy at . The local file is read and processed into a translation table for use by ZTX() and ZTX_translation_start(). lang: 2-character language code 'lc' ("de" "fr" "es" etc.) or 5-character language and region code 'lc_RC' ("de_AT" etc.) or null to use the current locale Status returned: 0 = OK, 1 = unable to process translation files. Translate a text string: cchar *translation = ZTX(cchar *english) english: text string which may have printf formats (%d %s ...) translation: the returned equivalent translation If the user language is English or if no translation is found, the input string is returned, else the translated string. example: program code: printf(ZTX("answer: %d %s \n next line"), 123, "qwerty"); A German .po file (translate-de.po) would have the following: msgid "" "answer: %d %s \n" " next line" msgstr "" "Antwort: %d %s \n" " nächste Zeile" ***************************************************************************/ namespace ZTXnames { FILE *fidr, *fidw; char buff[ZTXmaxcc], *ppq1, *ppq2; char *porec, *wporec; char Etext[ZTXmaxcc], Ttext[ZTXmaxcc]; // .po text: "line 1 %s \n" "line 2" char **etext, **ttext; // arrays, english and translations char **estring, **tstring; // merged, un-quoted, un-escaped int Ntext = 0; // array counts void ZTXgettext(char *text); char *ZTXmergetext(cchar *text); } // read and process .po file at application startup // prepare english strings and translations for quick access void ZTXinit(cchar *lang) // initialize translations { using namespace zfuncs; using namespace ZTXnames; int ii, err, Flocal = 0, Finstall = 0; time_t localdt = 0, installdt = 0; char localpo[200], installpo[200], ulocalesdir[200]; char *pp, poname[20], ponamexx[20]; struct stat statb; TRACE if (Ntext) { // free prior translation for (ii = 0; ii < Ntext; ii++) { zfree(etext[ii]); zfree(ttext[ii]); zfree(estring[ii]); zfree(tstring[ii]); } zfree(etext); zfree(ttext); zfree(estring); zfree(tstring); Ntext = 0; } etext = (char **) zmalloc(ZTXmaxent * sizeof(char *)); // english text and translations ttext = (char **) zmalloc(ZTXmaxent * sizeof(char *)); // (segmented, quoted, escaped) estring = (char **) zmalloc(ZTXmaxent * sizeof(char *)); // english strings and translations tstring = (char **) zmalloc(ZTXmaxent * sizeof(char *)); // (merged, un-quoted, un-escaped) if (lang && *lang) strncpy0(zlang,lang,6); // use language from caller else { // help Linux chaos pp = getenv("LANG"); // use $LANG if defined if (! pp) pp = getenv("LANGUAGE"); // use $LANGUAGE if defined if (! pp) pp = setlocale(LC_MESSAGES,""); // use locale if defined if (pp) strncpy0(zlang,pp,6); // "lc_RC" language/region code else strcpy(zlang,"en"); // use English } if (*zlang < 'a') strcpy(zlang,"en"); // use English if garbage printz("language: %s \n",zlang); if (strnEqu(zlang,"en",2)) return; // English, do nothing err = locale_filespec("userlocale","translate.po",localpo); if (! err) { Flocal = 1; // .po file was found in user area stat(localpo,&statb); localdt = statb.st_mtime; } err = locale_filespec("locale","translate.po",installpo); if (err) err = locale_filespec("locale","translate.po.gz",installpo); if (! err) { // install .po file was found Finstall = 1; stat(installpo,&statb); installdt = statb.st_mtime; } if (!

For a GTK stock item referenced with a macro like GTK_STOCK_OPEN, use the corresponding text name, like "gtk-open". For a custom icon, use the icon's file name like "my-icon.png". The file is expected to be in get_zdatadir()/icons. The icon file may be any size, and is resized to 32x32 for use on the toolbar. If the file is not found, the stock icon "gtk-missing-image" is used (".png" and ".jpg" files both work). For a button with no icon (text label only), use 0 or null for the icon argument. For a menu separator, use the menu name "separator". For a toolbar separator, use the label "separator". For a title menu (no response function), set the response function to null. The response function for both menus and toolbar buttons looks like this: void func(GtkWidget *, cchar *) The following macro is also supplied to simplify the coding of response functions: G_SIGNAL(window,event,func,arg) which expands to: g_signal_connect(G_OBJECT(window),event,G_CALLBACK(func),(void *) arg) ***************************************************************************/ // create menu bar and add to vertical packing box GtkWidget * create_menubar(GtkWidget *vbox) // icon size removed { GtkWidget *wmbar; wmbar = gtk_menu_bar_new(); gtk_box_pack_start(GTK_BOX(vbox),wmbar,0,0,0); return wmbar; } // add menu item to menu bar, with optional response function GtkWidget * add_menubar_item(GtkWidget *wmbar, cchar *mname, cbFunc func) { GtkWidget *wmitem; wmitem = gtk_menu_item_new_with_label(mname); gtk_menu_shell_append(GTK_MENU_SHELL(wmbar),wmitem); if (func) G_SIGNAL(wmitem,"activate",func,mname); return wmitem; } // add submenu item to menu item, with optional response function GtkWidget * add_submenu_item(GtkWidget *wmitem, cchar *mlab, cbFunc func, cchar *mtip) { GtkWidget *wmsub, *wmsubitem; wmsub = gtk_menu_item_get_submenu(GTK_MENU_ITEM(wmitem)); // add submenu if not already if (wmsub == null) { wmsub = gtk_menu_new(); gtk_menu_item_set_submenu(GTK_MENU_ITEM(wmitem),wmsub); } if (strEqu(mlab,"separator")) wmsubitem = gtk_separator_menu_item_new(); else wmsubitem = gtk_menu_item_new_with_label(mlab); // add menu item with label only gtk_menu_shell_append(GTK_MENU_SHELL(wmsub),wmsubitem); // append submenu item to submenu if (func) G_SIGNAL(wmsubitem,"activate",func,mlab); // connect optional response function if (mtip) g_object_set(G_OBJECT(wmsubitem),"tooltip-text",mtip,null); // add optional popup menu tip v.5.2 return wmsubitem; } /**************************************************************************/ // create toolbar and add to vertical packing box int tbIconSize = 24; // valid during toolbar construction GtkWidget * create_toolbar(GtkWidget *vbox, int iconsize) { using namespace zfuncs; GtkWidget *wtbar; wtbar = gtk_toolbar_new(); // gtk_toolbar_set_style(GTK_TOOLBAR(wtbar),GTK_TOOLBAR_BOTH); // v.5.8 gtk_box_pack_start(GTK_BOX(vbox),wtbar,0,0,0); tbIconSize = iconsize; return wtbar; } // add toolbar button with label and icon ("iconfile.png") and tool tip // at least one of label and icon should be present GtkWidget * add_toolbar_button(GtkWidget *wtbar, cchar *blab, cchar *btip, cchar *icon, cbFunc func) { using namespace zfuncs; GtkToolItem *tbutton; GError *gerror = 0; GdkPixbuf *pixbuf; GtkWidget *wicon = 0; char iconpath[200]; if (blab && strEqu(blab,"separator")) { tbutton = gtk_separator_tool_item_new(); gtk_toolbar_insert(GTK_TOOLBAR(wtbar),GTK_TOOL_ITEM(tbutton),-1); return (GtkWidget *) tbutton; } if (icon && *icon) { // get icon pixbuf *iconpath = 0; strncatv(iconpath,199,zicondir,"/",icon,null); pixbuf = gdk_pixbuf_new_from_file_at_scale(iconpath,tbIconSize,tbIconSize,1,&gerror); if (pixbuf) wicon = gtk_image_new_from_pixbuf(pixbuf); } tbutton = gtk_tool_button_new(wicon,blab); // v.5.8 if (! wicon) gtk_tool_button_set_icon_name(GTK_TOOL_BUTTON(tbutton),"gtk-missing-image"); if (btip) gtk_tool_item_set_tooltip_text(tbutton,btip); gtk_tool_item_set_homogeneous(tbutton,0); gtk_toolbar_insert(GTK_TOOLBAR(wtbar),GTK_TOOL_ITEM(tbutton),-1); if (func) G_SIGNAL(tbutton,"clicked",func,blab); return (GtkWidget *) tbutton; } /**************************************************************************/ // create a status bar and add to the start of a packing box GtkWidget * create_stbar(GtkWidget *pbox) { GtkWidget *stbar; static PangoFontDescription *fontdesc; stbar = gtk_statusbar_new(); fontdesc = pango_font_description_from_string("Monospace 9"); gtk_widget_override_font(stbar,fontdesc); gtk_box_pack_start(GTK_BOX(pbox),stbar,0,0,0); gtk_widget_show(stbar); return stbar; } // display message in status bar int stbar_message(GtkWidget *wstbar, cchar *message) { static int ctx = -1; if (ctx == -1) ctx = gtk_statusbar_get_context_id(GTK_STATUSBAR(wstbar),"all"); gtk_statusbar_pop(GTK_STATUSBAR(wstbar),ctx); gtk_statusbar_push(GTK_STATUSBAR(wstbar),ctx,message); return 0; } /************************************************************************** Popup Menu popup = create_popmenu() create a popup menu mitem = add_popmenu_item(popup, label, func, arg, tip) add menu item to popup menu popup_menu(GtkWidget *widget, popup) popup the menu at mouse position GtkWidget *popup, *mitem cchar *label, *arg, *tip void func(GtkWidget *, cchar *arg) Call 'create_popmenu' and then 'add_popmenu_item' for each item in the menu.

(e.g. a 10 megapix image needs about 0.36 seconds) NULL is returned if the function fails for one of the following: - pixbuf not 8 bits/channel or < 3 channels - unable to create output pixbuf (lack of memory?)
