Change Log

 New in version 3.1 (2009-05-12)

• Removing multiple files:
  In the directory listing, there are now checkboxes for selecting files and a button for removing them.
• Better distinction of objects in directory listing:
  For a better distinction of the objects in directory listing, every second object has a grey background now.
• Remote name for uploaded files:
  When uploading a file, you can now specify a name for the file on the server.
• Prefilled form fields:
  If you want to copy or rename/move a file or a directory or save a file using a different name, the form field for the new filename is prefilled with the old one. Additionally, the entered path is no more relative to the directory of the original file.
• Hide dot files:
  When the new configuration option hide_dot_files is set to 1, every file or directory beginning with a . is not shown in the directory listing. But you can still access the file / directory by typing its name into the Go to directory/file box.
  This option is also available in the user-dependent configuration.
• Copyright note:
  In the header of each file, there is a now a copyright note and a reference to the Artistic License.
• Template class updated:
  The template class was updated to version 2.0.

 New in version 3.0.1 (2005-11-10)

• Accessing files above the virtual root directory:
  It was possible to access files and directories above the virtual root directory beginning with the same string as the root directory.
  For example:
  If your root directory is /var/www/user1 it was possible to access /var/www/user10, /var/www/user11 and so on.

 New in version 3.0 (2005-10-18)

• Editing function changed:
  
  • The concept of locking the file for other users before editing it is not very good, causes some problems and makes it difficult to add new features. So I decided to remove it.
  • When Dev-Editor shows the form for editing a file, it calculates the MD5 checksum and places it in the editing form. Before saving the file, the MD5 checksum is calculated again and compared to the submitted one. If the two sums don't match, Dev-Editor does not save the file and shows the editing form.
  • In the edit dialogue, there is also a new submit button allowing to continue editing the file after saving it.
  • Removed the possibility of encoding ISO-8859-1 HTML entities when saving a file. I don't know if anybody used this function.
• Copy directories:
  Dev-Editor is now able to copy a directory.
• Forbid file access:
  The administrator may now define a list of files the user is not allowed to access.
• Individual configuration:
  Now, Dev-Editor is able to switch some configuration values depending on the current HTTP Auth user. This is controlled by a separate configuration file containing sections like Windows INI files (thus the configuration file parser is now able to parse files containing sections in square brackets). You may overwrite the following configuration values:
  • fileroot
  • httproot
  • forbidden (you may also clear the default forbidden list)
• Configuration files renamed:
  The extension of the configuration files is conf now.
• Names of error messages changed:
  I changed the names of some error messages:
  binary -> binary_file
cmd_unknown -> command_unknown
dir_read_fail -> dir_read_failed
create_ar -> create_above_root
not_exist -> not_found
• File names containing a "+" sign:
  If a file name contained a "+" sign, Dev-Editor was sometimes not able to access the file, because the "+" was interpreted as a space.
• Check octal numbers:
  Before changing the permissions of a file, Dev-Editor now checks if the user entered a valid octal number.
• Encoding of HTML entities:
  
  • All HTML in output is now properly encoded
  • HTML::Entities is a little bit slow and does currently not support very much encodings. Now, we just encode the HTML control characters (<, >, & and ").
    This also means that Dev-Editor now does not require any CPAN module.
• Template class updated:
  The template class was updated to version 1.5.
• Small changes:
  
  • Don't show the "Copy" link if a file is not readable
  • Added checkboxes in the "Copy" and "Rename" dialogues for immediately overwriting an existing file
  • Preserve the directory listing filter if the user changes the directory using the input field at the bottom of the directory listing

 New in version 2.3.2 (2005-04-23)

• Copying a file out of a directory:
  Fixed a really strange bug occuring only on Windows systems. Dev-Editor was not able to copy (or move) a file out of a directory if the path, the user entered in the corresponding dialogue, was beginning with ../.
• Empty root directory causes incomplete HTML table:
  Dev-Editor now does not create an incomplete HTML table if the root directory is completely empty or no files are matching against the current wildcard.
• move() instead of rename():
  Dev-Editor now uses the move() function from the File::Copy module to move or rename files and directories. move() is more reliable than the rename() function.
• No error message if reading of a directory failed:
  If reading of a directory failed, no error message was shown. I thought this bug was fixed...
• Template class updated:
  The template class was updated to version 1.4a.

 New in version 2.3.1 (2005-02-19)

• Handling of symbolic links changed:
  For security reasons, I completely changed the handling of symbolic links: Symbolic links are now treated as files, no matter where they point to. The user is just allowed to see the path where the link points to, he is allowed to delete the link, to rename it and to overwrite it by renaming an other file. Nothing else is allowed.
  Accessing a symbolic link pointing to a directory caused also a very strange effect: It was possible to access this directory, but you could not access the objects in it.
  I had to do it in this way because of the very stupid behaviour of abs_path() from the Cwd module: This function is just able to detect the absolute path of directories.
  Hard links are not affected by this, because it is not possible to detect them (at least I don't know how to detect them).
• Root directory must not be a symbolic link:
  Now, the root directory must not be a symbolic link.
  Sorry for this, I really would have liked to allow the root directory to be a symbolic link, but if I would allow this, Dev-Editor would not be able to create files in the root directory. I'm looking for an alternative...
• Use Greenwich Mean Time:
  You may now use Greenwich Mean Time (GMT/UTC) in dates instead of the local time.
  I don't know if anyone needs this, but it could be useful.
• Handle errors produced by File::UseList:
  • Check if unlocking of the list of files in use was successful
  • Check if a file could be successfully added to the list of files in use
  • Check if a file could be successfully removed from the list of files in use
• Saving to non-existing files:
  The file saving process was aborted if the user wanted to write text data using the edit function into a file that does not exists.
  The reason was that Dev-Editor thought that this non-existing file was a binary file.
• Template class updated:
  The template class was updated to version 1.4.
  This fixes the problem of the endless loops produced by incorrectly nested {IF} blocks.
• Small changes:
  • Files locked with the flock() function are now unlocked by the close() function due to security reasons (see http://forum.de.selfhtml.org/?t=101375&m=622582)
  • Changed the names of two error messages:
    dircopy -> dir_copy
editdir -> dir_edit
  • Fixed various small errors in some template files
  • The regular expression used by file_name() and upper_path() to detect Windows drive letters was not case-insensitive

 New in version 2.3 (2005-01-08)

• Filter directory listing:
  Dev-Editor is now able to filter the directory listing using DOS-style wildcards.
  I think that is a little bit incomplete, Dev-Editor should be able to "remember" the filter wildcard during the actions.
  The code for parsing DOS-style wildcards is from the File::DosGlob module by Gurusamy Sarathy.
• flock():
  Dev-Editor now uses flock().
  flock() is called using a wrapper function which checks if it is really available.
• check_path() broken on Windows:
  On Windows systems the check_path() routine was heavily broken (this routine checks if someone tries to access a path above the virtual root directory). It was possible to access files above the root directory by accessing a path with ... or .... or something like that as the last path component. This bug was caused by the rewrite of check_path() in Dev-Editor 2.2.
• . or .. as end of a path:
  If you enter a path with . or .. as the last path component, Dev-Editor showed a really strange behaviour by allowing to enter a path like something/. or something/... This was also caused by the (poor) rewrite of check_path(). The problem is fixed now.
• Paths beginning with /../ caused problems:
  When composing the temporary virtual path for a new file, don't call clean_path(). It is unnecessary and it also caused a problem if this path would begin with /../, because on UNIX systems, canonpath() removes /../ at the beginning of a path. So if a user wanted to create the file /../file.ext (but he wasn't allowed to), he created /file.ext.
• Deny changing file properties in some cases:
  
  • Do not allow to change the properties of the root directory
  • Do not allow to change the properties of a file in use
• Deny overwriting files:
  
  • While processing a file upload, check if the user wants to replace a directory or overwrite a write-protected file
  • If the user wants to copy or rename a file, check if he wants to overwrite a write-protected file
  • Do not allow to upload a file if a file with the same virtual name is currently in use
• Validate file uploads:
  Dev-Editor now tries to validate a file upload by checking the handle created by the CGI module.
• Improved configuration file parser:
  
  • The parser now ignores lines like that:
       = Value
    Such lines could lead to properties with empty keys in the configuration hash.
  • Allow configuration options with empty values
  • If a option is defined twice, the line number of the second one is shown in the error message
• Output changes:
  
  • More encoding of HTML entities
  • In directory listing, the Edit link of files in use were not greyed (very nasty)
  • Show the name of the lock file in error messages even if it has not been defined in the configuration file
• Small internal changes:
  
  • The file saving process is now completely centralized in File::Access
  • When generating a redirection header, check if we really have to create a query string
  • Fixed a bug occuring if the curdir CGI parameter had no trailing slash and the newfile parameter had no leading slash
  • Dev-Editor now takes more care of Windows drive letters
  • Trying to increase speed of the script by surrounding static values by single quotes
  • Code cleaning

 New in version 2.2a (2004-11-29)

• File uploads did not work:
  Dev-Editor normally tests if it has enough permissions to upload a file to a directory. But the condition was missing and so Dev-Editor always aborted file uploads and didn't even display the dialogue.

 New in version 2.2 (2004-11-27)

• `chgrp` system command and numerical group names:
  When changing the group, Dev-Editor is now using the `chgrp` system command.
  This allows to use numerical group names. Before, Dev-Editor handled numerical values as group IDs.
• Checking root directory:
  Dev-Editor now checks if the root directory exists and if it may be accessed.
  This fixed also bug where it was possible to access the physical root directory if Dev-Editor could not enter the virtual root directory.
• Checking directory permissions:
  Dev-Editor does some simple checks of directory permissions now:
  • Inaccessible directories are greyed in directory listing. You cannot access them, but the actions are not disabled, because they may work.
  • Actions needing write access to a directory are aborted if Dev-Editor has no write access.
• Access a directory structure similar to the root directory:
  The path the user wants to access must now begin with the root directory. The old check made it possible to access a directory structure outside the root directory similar to the root directory.
• Changing mode of a directory with mode 000:
  It was not possible to change the mode of a directory with mode 000.
• Upload only to directories:
  Dev-Editor now checks if the user really uploads a file to a directory.
• Improved About dialogue:
  • Dev-Editor now only shows the main group ID of the process user.
  • Dev-Editor also shows the current umask of the process.
  • Special chars in most values are now encoded to entities.
• Added <label> tags:
  For a better usability in some browsers, I added <label> tags for the checkboxes and radio buttons in file edit and file upload dialogue.
• Directory links in error messages:
  Some error messages generated by the main program now contain a link to the root directory.
• Bugs in HTML generation:
  • If Dev-Editor could not read a directory, it did neither display an error message nor a directory link.
  • Some error messages had problems with {DIR} variables. Thus the variable in error.htm which will be replaced by a back link is now called {BACK}.
  • When viewing a file, Dev-Editor inserts the contents of the file into the viewfile.htm template file after parsing the editable {IF}-block, because Dev-Editor showed a very ugly behaviour when viewing this template file.
• Code cleaning:
  I tried to clean the source code of Dev-Editor a little bit. Some parts of the code were optimized.

 New in version 2.1a (2004-10-22)

• Changed file saving error handling:
  Now we already unlock the file saving process, because if an error occurs during this process, the file keeps locked.
  This is not a perfect solution, there are still problems. I have to figure out another one.

 New in version 2.1 (2004-10-14)

• Overwrite files during file upload:
  In file upload dialogue, there is a new checkbox which allows to overwrite files during file upload if they already exist.
• Improved file saving:
  The process of file saving has been improved:
  • Saving even works if the file has to be created first.
  • Dev-Editor is now checking if the user wants to write text data into a binary file.
  • If the user just entered spaces as filename (detection works for other commands using the newfile CGI parameter too), we use the original filename.
• Don't copy a directory:
  Dev-Editor now denies copying a directory.
• Check before manually unlocking:
  Dev-Editor now checks if the file is really locked before displaying the dialogue for manually unlocking a file. If it is not locked, Dev-Editor returns to directory view. Dev-Editor also behaves in this way if it is trying to unlock a file.
• Wrong error messages:
  Something definitely went wrong when I remade the copy and the rename functions: They printed a wrong error message if the destination already existed and if it was a file.

 New in version 2.0 (2004-08-10)

• File uploads:
  Dev-Editor is now able to process HTTP file uploads. The files may be transferred in ASCII or binary mode (similar to FTP).
• Change mode and group:
  Dev-Editor is now able to change the mode and the group of a file or a directory.
• HTTPS support and non-default ports:
  Dev-Editor is now able to detect a HTTPS connection and if the web server doesn't listen on the default ports (necessary for reloading Dev-Editor).
• Do not allow removing or renaming the root directory:
  Dev-Editor now denies removing or renaming the root directory.
• Renaming files outside the root directory:
  There was a bug which caused Dev-Editor not to rename files outside the root directory if they already exist.
• Improved file editing:
  When the user wants to save an edited file using a different file name, Dev-Editor now unlocks the original file and checks if a file with this different name already exists and if it is locked.
• Improved file creating:
  The routine which creates empty files had a race condition which could set files to 0 if they already exist.
• Maximum size for files:
  The administrator may now define a maximum size for files in the main configuration file. If the user wants to view or edit a file larger than this defined size, Dev-Editor denies file access (but the file can still be copied, renamed or removed).
• Form for creating new files or directories:
  In directory listing, when clicking on the buttons next to the fields for creating new files and directories without entering a file or directory name, the user got an error message which is a little bit strange.
  Now, the user will see a form for creating new files or directories.
• Newlines are converted while reading:
  Whenever Dev-Editor now reads a file for output, it converts any line separator to the system specific one.
• Case-insensitive commands:
  The commands are now case-insensitive, so the command ShOw is the same as show.
• About screen:
  There is now a small "About" screen which shows some more or less useful information about Dev-Editor and the system.
• Improvements for user interface:
  Made a lot of improvements for the user interface:
  • The directory listing is now built using tables.
  • When editing a file and the user wants to save a file using a different file name, the checkbox for saving the file using a different file name is activated using JavaScript.
  • In directory listing or when viewing a file, there is a new field for quickly jumping to a file or to a directory.
  • Separated "Work with directory" and "Work with file" into different options in directory listing ("Copy", "Rename", "Delete", "Unlock"). The options also have their own dialogues.
  • In directory listing, there is a new link for viewing a file or a directory in the browser.
  • When viewing a file and if the file is editable, there is a new link to edit this file.
  • Files and directories in directory listing are now sorted case-insensitively.
• Configuration files:
  The settings of Dev-Editor are now stored in extern configuration files: There is one file for general settings, one for the error messages and one for the paths to the template files.
• Templates:
  The output of Dev-Editor is now controlled by template files. The source code became much cleaner :-)

 New in version 1.2 (2003-12-29)

• Removing directories:
  Dev-Editor is now able to completely remove a directory.
• "Work with directories":
  In directory listing, next do a directory, there is a new link called "Work with directory". When you select this link, you get a form to remove or rename/move the directory.
  Additionally, the link "Do other stuff" was renamed to "Work with file".
• Overwriting existing files:
  If you want to copy a file, and the destination file already exists, you will be asked to overwrite the file. If the destination points to a directory, copying will be aborted completely.
  If you want to rename a file or a directory, and the destination file already exists, you will be asked to overwrite the file. If the destination points to a directory, renaming will be aborted completely.
• Confirmation for removing files:
  If you want to remove a file, a confirmation dialog will be displayed first.
• Fixed open() calls:
  It seems that some systems don't support the FILEHANDLE,MODE,FILENAME version of open(). Now we don't use it any more.
• Default permissions for mkdir():
  Set the permissions for mkdir() to 0777. I thought it is optional (as described in perlfunc), but some systems need it.

 New in version 1.1 (2003-11-15)

• Newlines are converted:
  Any line seperator will now be converted to the system specific line seperator if you save a text file.
• File permissions are checked:
  Dev-Editor now runs some simple checks on the file permissions when it creates a directory listing, tries to view or edit a file and when it copies a file.
• Tool tips for file status:
  In directory listing, when a file cannot be viewed or edited, a tool tip on the "View" or "Edit" link will show the reason why it is so.
• File permissions are saved:
  When the user saves a text file, the file permissions were destroyed. The reason was that a temporary file was used, which was renamed to the originally file. Now this is fixed, but if saving of the file now fails, the file could be damaged...
• Links in error messages:
  Some error messages now contain a link to go back to the directory containing the file which caused the error.
• Typos fixed:
  There were a lot of typos in the output, the comments and the ReadMe file.
• Dates fixed:
  The dates of the last modification in the head comment of the files had the wrong format. They had the format MM-DD-YYYY, but they should have YYYY-MM-DD.
  Sorry, that was very embarassing...

 New in version 1.0 (2003-10-08)

• First public release:
  This is the first public release of Dev-Editor.
