CHANGELOG

   1 Change Log for Dev-Editor
   2 =========================
   3
   4 New in version 2.3.2 (2005-04-23)
   5 ---------------------------------
   6
   7  Copying a file out of a directory:
   8  ----------------------------------
   9  Fixed a really strange bug occuring only on Windows systems.
  10  Dev-Editor was not able to copy (or move) a file out of a directory if the
  11  path, the user entered in the corresponding dialogue, was beginning with "../".
  12
  13  Empty root directory causes incomplete HTML table:
  14  --------------------------------------------------
  15  Dev-Editor now does not create an incomplete HTML table if the root directory
  16  is completely empty or no files are matching against the current wildcard.
  17
  18  move() instead of rename():
  19  ---------------------------
  20  Dev-Editor now uses the move() function from the File::Copy module to move or
  21  rename files and directories. move() is more reliable than the rename()
  22  function.
  23
  24  No error message if reading of a directory failed:
  25  --------------------------------------------------
  26  If reading of a directory failed, no error message was shown. I thought this
  27  bug was fixed...
  28
  29  Template class updated:
  30  -----------------------
  31  The template class was updated to version 1.4a.
  32
  33 New in version 2.3.1 (2005-02-19)
  34 ---------------------------------
  35
  36  Handling of symbolic links changed:
  37  -----------------------------------
  38  For security reasons, I completely changed the handling of symbolic links:
  39  Symbolic links are now treated as files, no matter where they point to. The
  40  user is just allowed to see the path where the link points to, he is allowed to
  41  delete the link, to rename it and to overwrite it by renaming an other file.
  42  Nothing else is allowed.
  43  Accessing a symbolic link pointing to a directory caused also a very strange
  44  effect: It was possible to access this directory, but you could not access
  45  the objects in it.
  46  I had to do it in this way because of the very stupid behaviour of abs_path()
  47  from the Cwd module: This function is just able to detect the absolute path of
  48  directories.
  49  Hard links are not affected by this, because it is not possible to detect them
  50  (at least I don't know how to detect them).
  51
  52  Root directory must not be a symbolic link:
  53  -------------------------------------------
  54  Now, the root directory must not be a symbolic link.
  55  Sorry for this, I really would have liked to allow the root directory to be a
  56  symbolic link, but if I would allow this, Dev-Editor would not be able to
  57  create files in the root directory. I'm looking for an alternative...
  58
  59  Use Greenwich Mean Time:
  60  ------------------------
  61  You may now use Greenwich Mean Time (GMT/UTC) in dates instead of the local
  62  time.
  63  I don't know if anyone needs this, but it could be useful.
  64
  65  Handle errors produced by File::UseList:
  66  ----------------------------------------
  67  - Check if unlocking of the list of files in use was successful
  68  - Check if a file could be successfully added to the list of files in use
  69  - Check if a file could be successfully removed from the list of files in use
  70
  71  Saving to non-existing files:
  72  -----------------------------
  73  The file saving process was aborted if the user wanted to write text data using
  74  the edit function into a file that does not exists.
  75  The reason was that Dev-Editor thought that this non-existing file was a binary
  76  file.
  77
  78  Template class updated:
  79  -----------------------
  80  The template class was updated to version 1.4.
  81  This fixes the problem of the infinitive loops produced by incorrectly nested
  82  {IF} blocks.
  83
  84  Small changes:
  85  --------------
  86  - Files locked with the flock() function are now unlocked by the close()
  87    function due to security reasons (see
  88    http://forum.de.selfhtml.org/?t=101375&m=622582)
  89  - Changed the names of two error messages:
  90    dircopy -> dir_copy
  91    editdir -> dir_edit
  92  - Fixed various small errors in some template files
  93  - The regular expression used by file_name() and upper_path() to detect Windows
  94    drive letters was not case-insensitive
  95
  96 New in version 2.3 (2005-01-08)
  97 -------------------------------
  98
  99  Filter directory listing:
 100  -------------------------
 101  Dev-Editor is now able to filter the directory listing using DOS-style
 102  wildcards.
 103  I think that is a little bit incomplete, Dev-Editor should be able to
 104  "remember" the filter wildcard during the actions.
 105  The code for parsing DOS-style wildcards is from the File::DosGlob module by
 106  Gurusamy Sarathy.
 107
 108  flock():
 109  --------
 110  Dev-Editor now uses flock().
 111  flock() is called using a wrapper function which checks if it is really
 112  available.
 113
 114  check_path() broken on Windows:
 115  -------------------------------
 116  On Windows systems the check_path() routine was heavily broken (this routine
 117  checks if someone tries to access a path above the virtual root directory). It
 118  was possible to access files above the root directory by accessing a path with
 119  "..." or "...." or something like that as the last path component. This bug was
 120  caused by the rewrite of check_path() in Dev-Editor 2.2.
 121
 122  "." or ".." as end of a path:
 123  -----------------------------
 124  If you enter a path with "." or ".." as the last path component, Dev-Editor
 125  showed a really strange behaviour by allowing to enter a path like
 126  "something/." or "something/..". This was also caused by the (poor) rewrite of
 127  check_path(). The problem is fixed now.
 128
 129  Paths beginning with "/../" caused problems:
 130  --------------------------------------------
 131  When composing the temporary virtual path for a new file, don't call
 132  clean_path(). It is unnecessary and it also caused a problem if this path would
 133  begin with /../, because on UNIX systems, canonpath() removes /../ at the
 134  beginning of a path. So if a user wanted to create the file /../file.ext (but
 135  he wasn't allowed to), he created /file.ext.
 136
 137  Deny changing file properties in some cases:
 138  --------------------------------------------
 139  - Do not allow to change the properties of the root directory
 140  - Do not allow to change the properties of a file in use
 141
 142  Deny overwriting files:
 143  -----------------------
 144  - While processing a file upload, check if the user wants to replace a
 145    directory or overwrite a write-protected file
 146  - If the user wants to copy or rename a file, check if he wants to overwrite a
 147    write-protected file
 148  - Do not allow to upload a file if a file with the same virtual name is
 149    currently in use
 150
 151  Validate file uploads:
 152  ----------------------
 153  Dev-Editor now tries to validate a file upload by checking the handle created
 154  by the CGI module.
 155
 156  Improved configuration file parser:
 157  -----------------------------------
 158  - The parser now ignores lines like that:
 159       = Value
 160    Such lines could lead to properties with empty keys in the configuration
 161    hash.
 162  - Allow configuration options with empty values
 163  - If a option is defined twice, the line number of the second one is shown in
 164    the error message
 165
 166  Output changes:
 167  ---------------
 168  - More encoding of HTML entities
 169  - In directory listing, the "Edit" link of files in use were not greyed (very
 170    nasty)
 171  - Show the name of the lock file in error messages even if it has not been
 172    defined in the configuration file
 173
 174  Small internal changes:
 175  -----------------------
 176  - The file saving process is now completely centralized in File::Access
 177  - When generating a redirection header, check if we really have to create a
 178    query string
 179  - Fixed a bug occuring if the "curdir" CGI parameter had no trailing slash and
 180    the "newfile" parameter had no leading slash
 181  - Dev-Editor now takes more care of Windows drive letters
 182  - Trying to increase speed of the script by surrounding static values by single
 183    quotes
 184  - Code cleaning
 185
 186 New in version 2.2a (2004-11-29)
 187 --------------------------------
 188
 189  File uploads did not work:
 190  --------------------------
 191  Dev-Editor normally tests if it has enough permissions to upload a file to a
 192  directory. But the condition was missing and so Dev-Editor always aborted file
 193  uploads and didn't even display the dialogue.
 194
 195 New in version 2.2 (2004-11-27)
 196 -------------------------------
 197
 198  `chgrp` system command and numerical group names:
 199  -------------------------------------------------
 200  When changing the group, Dev-Editor is now using the `chgrp` system command.
 201  This allows to use numerical group names. Before, Dev-Editor handled numerical
 202  values as group IDs.
 203
 204  Checking root directory:
 205  ------------------------
 206  Dev-Editor now checks if the root directory exists and if it may be accessed.
 207  This fixed also bug where it was possible to access the physical root directory
 208  if Dev-Editor could not enter the virtual root directory.
 209
 210  Checking directory permissions:
 211  -------------------------------
 212  Dev-Editor does some simple checks of directory permissions now:
 213  - Inaccessible directories are greyed in directory listing. You cannot access
 214    them, but the actions are not disabled, because they may work.
 215  - Actions needing write access to a directory are aborted if Dev-Editor has no
 216    write access.
 217
 218  Access a directory structure similar to the root directory:
 219  -----------------------------------------------------------
 220  The path the user wants to access must now BEGIN with the root directory. The
 221  old check made it possible to access a directory structure outside the root
 222  directory similar to the root directory.
 223
 224  Changing mode of a directory with mode 000:
 225  -------------------------------------------
 226  It was not possible to change the mode of a directory with mode 000.
 227
 228  Upload only to directories:
 229  ---------------------------
 230  Dev-Editor now checks if the user really uploads a file to a directory.
 231
 232  Improved About dialogue:
 233  ------------------------
 234  - Dev-Editor now only shows the main group ID of the process user.
 235  - Dev-Editor also shows the current umask of the process.
 236  - Special chars in most values are now encoded to entities.
 237
 238  Added <label> tags:
 239  -------------------
 240  For a better usability in some browsers, I added <label> tags for the
 241  checkboxes and radio buttons in file edit and file upload dialogue.
 242
 243  Directory links in error messages:
 244  ----------------------------------
 245  Some error messages generated by the main program now contain a link to the
 246  root directory.
 247
 248  Bugs in HTML generation:
 249  ------------------------
 250  - If Dev-Editor could not read a directory, it did neither display an error
 251    message nor a directory link.
 252  - Some error messages had problems with {DIR} variables. Thus the variable in
 253    error.htm which will be replaced by a back link is now called "{BACK}".
 254  - When viewing a file, Dev-Editor inserts the contents of the file into the
 255    viewfile.htm template file AFTER parsing the "editable" {IF}-block, because
 256    Dev-Editor showed a very ugly behaviour when viewing this template file.
 257
 258  Code cleaning:
 259  --------------
 260  I tried to clean the source code of Dev-Editor a little bit. Some parts of the
 261  code were optimized.
 262
 263 New in version 2.1a (2004-10-22)
 264 --------------------------------
 265
 266  Changed file saving error handling:
 267  -----------------------------------
 268  Now we already unlock the file saving process, because if an error occurs
 269  during this process, the file keeps locked.
 270  This is not a perfect solution, there are still problems. I have to figure out
 271  another one.
 272
 273 New in version 2.1 (2004-10-14)
 274 -------------------------------
 275
 276  Overwrite files during file upload:
 277  -----------------------------------
 278  In file upload dialogue, there is a new checkbox which allows to overwrite
 279  files during file upload if they already exist.
 280
 281  Improved file saving:
 282  ---------------------
 283  The process of file saving has been improved:
 284  - Saving even works if the file has to be created first.
 285  - Dev-Editor is now checking if the user wants to write text data into a binary
 286    file.
 287  - If the user just entered spaces as filename (detection works for other
 288    commands using the "newfile" CGI parameter too), we use the original
 289    filename.
 290
 291  Don't copy a directory:
 292  -----------------------
 293  Dev-Editor now denies copying a directory.
 294
 295  Check before manually unlocking:
 296  --------------------------------
 297  Dev-Editor now checks if the file is really locked before displaying the
 298  dialogue for manually unlocking a file. If it is not locked, Dev-Editor returns
 299  to directory view. Dev-Editor also behaves in this way if it is trying to
 300  unlock a file.
 301
 302  Wrong error messages:
 303  ---------------------
 304  Something definitely went wrong when I remade the copy and the rename
 305  functions: They printed a wrong error message if the destination already
 306  existed and if it was a file.
 307
 308 New in version 2.0 (2004-08-10)
 309 -------------------------------
 310
 311  File uploads:
 312  -------------
 313  Dev-Editor is now able to process HTTP file uploads. The files may be
 314  transferred in ASCII or binary mode (similar to FTP).
 315
 316  Change mode and group:
 317  ----------------------
 318  Dev-Editor is now able to change the mode and the group of a file or a
 319  directory.
 320
 321  HTTPS support and non-default ports:
 322  ------------------------------------
 323  Dev-Editor is now able to detect a HTTPS connection and if the web server
 324  doesn't listen on the default ports (necessary for reloading Dev-Editor).
 325
 326  Do not allow removing or renaming the root directory:
 327  -----------------------------------------------------
 328  Dev-Editor now denies removing or renaming the root directory.
 329
 330  Renaming files outside the root directory:
 331  ------------------------------------------
 332  There was a bug which caused Dev-Editor not to rename files outside the root
 333  directory if they already exist.
 334
 335  Improved file editing:
 336  ----------------------
 337  When the user wants to save an edited file using a different file name,
 338  Dev-Editor now unlocks the original file and checks if a file with this
 339  different name already exists and if it is locked.
 340
 341  Improved file creating:
 342  -----------------------
 343  The routine which creates empty files had a race condition which could set
 344  files to 0 if they already exist.
 345
 346  Maximum size for files:
 347  -----------------------
 348  The administrator may now define a maximum size for files in the main
 349  configuration file. If the user wants to view or edit a file larger than this
 350  defined size, Dev-Editor denies file access (but the file can still be copied,
 351  renamed or removed).
 352
 353  Form for creating new files or directories:
 354  -------------------------------------------
 355  In directory listing, when clicking on the buttons next to the fields for
 356  creating new files and directories without entering a file or directory name,
 357  the user got an error message which is a little bit strange.
 358  Now, the user will see a form for creating new files or directories.
 359
 360  Newlines are converted while reading:
 361  -------------------------------------
 362  Whenever Dev-Editor now reads a file for output, it converts any line separator
 363  to the system specific one.
 364
 365  Case-insensitive commands:
 366  --------------------------
 367  The commands are now case-insensitive, so the command "ShOw" is the same as
 368  "show".
 369
 370  About screen:
 371  -------------
 372  There is now a small "About" screen which shows some more or less useful
 373  information about Dev-Editor and the system.
 374
 375  Improvements for user interface:
 376  --------------------------------
 377  Made a lot of improvements for the user interface:
 378  - The directory listing is now built using tables.
 379  - When editing a file and the user wants to save a file using a different file
 380    name, the checkbox for saving the file using a different file name is
 381    activated using JavaScript.
 382  - In directory listing or when viewing a file, there is a new field for quickly
 383    jumping to a file or to a directory.
 384  - Separated "Work with directory" and "Work with file" into different options
 385    in directory listing ("Copy", "Rename", "Delete", "Unlock"). The options also
 386    have their own dialogues.
 387  - In directory listing, there is a new link for viewing a file or a directory
 388    in the browser.
 389  - When viewing a file and if the file is editable, there is a new link to edit
 390    this  file.
 391  - Files and directories in directory listing are now sorted case-insensitively.
 392
 393  Configuration files:
 394  --------------------
 395  The settings of Dev-Editor are now stored in extern configuration files: There
 396  is one file for general settings, one for the error messages and one for the
 397  paths to the template files.
 398
 399  Templates:
 400  ----------
 401  The output of Dev-Editor is now controlled by template files. The source code
 402  became much cleaner :-)
 403
 404 New in version 1.2 (2003-12-29)
 405 -------------------------------
 406
 407  Removing directories:
 408  ---------------------
 409  Dev-Editor is now able to completely remove a directory.
 410
 411  "Work with directories":
 412  ------------------------
 413  In directory listing, next do a directory, there is a new link called "Work
 414  with directory". When you select this link, you get a form to remove or
 415  rename/move the directory.
 416  Additionally, the link "Do other stuff" was renamed to "Work with file".
 417
 418  Overwriting existing files:
 419  ---------------------------
 420  If you want to copy a file, and the destination file already exists, you will
 421  be asked to overwrite the file. If the destination points to a directory,
 422  copying will be aborted completely.
 423  If you want to rename a file or a directory, and the destination file already
 424  exists, you will be asked to overwrite the file. If the destination points to a
 425  directory, renaming will be aborted completely.
 426
 427  Confirmation for removing files:
 428  --------------------------------
 429  If you want to remove a file, a confirmation dialog will be displayed first.
 430
 431  Fixed open() calls:
 432  -------------------
 433  It seems that some systems don't support the FILEHANDLE,MODE,FILENAME version
 434  of open(). Now we don't use it any more.
 435
 436  Default permissions for mkdir():
 437  --------------------------------
 438  Set the permissions for mkdir() to 0777. I thought it is optional (as described
 439  in "perlfunc"), but some systems need it.
 440
 441 New in version 1.1 (2003-11-15)
 442 -------------------------------
 443
 444  Newlines are converted:
 445  -----------------------
 446  Any line seperator will now be converted to the system specific line seperator
 447  if you save a text file.
 448
 449  File permissions are checked:
 450  -----------------------------
 451  Dev-Editor now runs some simple checks on the file permissions when it creates
 452  a directory listing, tries to view or edit a file and when it copies a file.
 453
 454  Tool tips for file status:
 455  --------------------------
 456  In directory listing, when a file cannot be viewed or edited, a tool tip on the
 457  "View" or "Edit" link will show the reason why it is so.
 458
 459  File permissions are saved:
 460  ---------------------------
 461  When the user saves a text file, the file permissions were destroyed. The
 462  reason was that a temporary file was used, which was renamed to the originally
 463  file. Now this is fixed, but if saving of the file now fails, the file could be
 464  damaged...
 465
 466  Links in error messages:
 467  ------------------------
 468  Some error messages now contain a link to go back to the directory containing
 469  the file which caused the error.
 470
 471  Typos fixed:
 472  ------------
 473  There were a lot of typos in the output, the comments and the ReadMe file.
 474
 475  Dates fixed:
 476  ------------
 477  The dates of the last modification in the head comment of the files had the
 478  wrong format. They had the format MM-DD-YYYY, but they should have YYYY-MM-DD.
 479  Sorry, that was VERY embarassing...
 480
 481 New in version 1.0 (2003-10-08)
 482 -------------------------------
 483
 484  First public release:
 485  ---------------------
 486  This is the first public release of Dev-Editor.
 487
 488 ------------------------------------------------
