CHANGELOG

   1 Change Log for Dev-Editor
   2 =========================
   3
   4 Version 3.x.x (200x-xx-xx):
   5 ===========================
   6
   7  Removing multiple files:
   8  ------------------------
   9  In the directory listing, there are now checkboxes for selecting files and a
  10  button for removing them.
  11
  12  Better distinction of objects in directory listing:
  13  ---------------------------------------------------
  14  For a better distinction of the objects in directory listing, every second
  15  object has a grey background now.
  16
  17  Prefilled form fields:
  18  ----------------------
  19  If you want to copy or rename/move a file or a directory or save a file using
  20  a different name, the form field for the new filename is prefilled with the
  21  old one. Additionally, the entered path is no more relative to the directory
  22  of the original file.
  23
  24  Hide dot files:
  25  ---------------
  26  When the new configuration option "hide_dot_files" is set to 1, every file or
  27  directory beginning with a "." is not shown in the directory listing. But you
  28  can still access the file / directory by typing its name into the "Go to
  29  directory/file" box.
  30  This option is also available in the user-dependent configuration.
  31
  32  Copyright note:
  33  ---------------
  34  In the header of each file, there is a now a copyright note and a reference to
  35  the Artistic License.
  36
  37  Template class updated:
  38  -----------------------
  39  The template class was updated to version 2.0.
  40
  41 Version 3.0.1 (2005-11-10):
  42 ===========================
  43
  44  Accessing files above the virtual root directory:
  45  -------------------------------------------------
  46  It was possible to access files and directories above the virtual root
  47  directory beginning with the same string as the root directory.
  48  For example:
  49  If your root directory is "/var/www/user1" it was possible to access
  50  "/var/www/user10", "/var/www/user11" and so on.
  51
  52 Version 3.0 (2005-10-18):
  53 =========================
  54
  55  Editing function changed:
  56  -------------------------
  57  - The concept of locking the file for other users before editing it is not very
  58    good, causes some problems and makes it difficult to add new features. So I
  59    decided to remove it.
  60  - When Dev-Editor shows the form for editing a file, it calculates the MD5
  61    checksum and places it in the editing form. Before saving the file, the MD5
  62    checksum is calculated again and compared to the submitted one. If the two
  63    sums don't match, Dev-Editor does not save the file and shows the editing
  64    form.
  65  - In the edit dialogue, there is also a new submit button allowing to continue
  66    editing the file after saving it.
  67  - Removed the possibility of encoding ISO-8859-1 HTML entities when saving a
  68    file. I don't know if anybody used this function.
  69
  70  Copy directories:
  71  -----------------
  72  Dev-Editor is now able to copy a directory.
  73
  74  Forbid file access:
  75  -------------------
  76  The administrator may now define a list of files the user is not allowed to
  77  access.
  78
  79  Individual configuration:
  80  -------------------------
  81  Now, Dev-Editor is able to switch some configuration values depending on the
  82  current HTTP Auth user.
  83  This is controlled by a separate configuration file containing sections like
  84  Windows INI files (thus the configuration file parser is now able to parse
  85  files containing sections in square brackets).
  86  You may overwrite the following configuration values:
  87  - fileroot
  88  - httproot
  89  - forbidden (you may also clear the default "forbidden" list)
  90
  91  Configuration files renamed:
  92  ----------------------------
  93  The extension of the configuration files is "conf" now.
  94
  95  Names of error messages changed:
  96  --------------------------------
  97  I changed the names of some error messages:
  98  binary        -> binary_file
  99  cmd_unknown   -> command_unknown
 100  dir_read_fail -> dir_read_failed
 101  create_ar     -> create_above_root
 102  not_exist     -> not_found
 103
 104  File names containing a "+" sign:
 105  ---------------------------------
 106  If a file name contained a "+" sign, Dev-Editor was sometimes not able to
 107  access the file, because the "+" was interpreted as a space.
 108
 109  Check octal numbers:
 110  --------------------
 111  Before changing the permissions of a file, Dev-Editor now checks if the user
 112  entered a valid octal number.
 113
 114  Encoding of HTML entities:
 115  --------------------------
 116  - All HTML in output is now properly encoded
 117  - HTML::Entities is a little bit slow and does currently not support very much
 118    encodings. Now, we just encode the HTML control characters (<, >, & and ").
 119    This also means that Dev-Editor now does not require any CPAN module.
 120
 121  Template class updated:
 122  -----------------------
 123  The template class was updated to version 1.5.
 124
 125  Small changes:
 126  --------------
 127  - Don't show the "Copy" link if a file is not readable
 128  - Added checkboxes in the "Copy" and "Rename" dialogues for immediately
 129    overwriting an existing file
 130  - Preserve the directory listing filter if the user changes the directory using
 131    the input field at the bottom of the directory listing
 132
 133 New in version 2.3.2 (2005-04-23)
 134 ---------------------------------
 135
 136  Copying a file out of a directory:
 137  ----------------------------------
 138  Fixed a really strange bug occuring only on Windows systems.
 139  Dev-Editor was not able to copy (or move) a file out of a directory if the
 140  path, the user entered in the corresponding dialogue, was beginning with "../".
 141
 142  Empty root directory causes incomplete HTML table:
 143  --------------------------------------------------
 144  Dev-Editor now does not create an incomplete HTML table if the root directory
 145  is completely empty or no files are matching against the current wildcard.
 146
 147  move() instead of rename():
 148  ---------------------------
 149  Dev-Editor now uses the move() function from the File::Copy module to move or
 150  rename files and directories. move() is more reliable than the rename()
 151  function.
 152
 153  No error message if reading of a directory failed:
 154  --------------------------------------------------
 155  If reading of a directory failed, no error message was shown. I thought this
 156  bug was fixed...
 157
 158  Template class updated:
 159  -----------------------
 160  The template class was updated to version 1.4a.
 161
 162 New in version 2.3.1 (2005-02-19)
 163 ---------------------------------
 164
 165  Handling of symbolic links changed:
 166  -----------------------------------
 167  For security reasons, I completely changed the handling of symbolic links:
 168  Symbolic links are now treated as files, no matter where they point to. The
 169  user is just allowed to see the path where the link points to, he is allowed to
 170  delete the link, to rename it and to overwrite it by renaming an other file.
 171  Nothing else is allowed.
 172  Accessing a symbolic link pointing to a directory caused also a very strange
 173  effect: It was possible to access this directory, but you could not access
 174  the objects in it.
 175  I had to do it in this way because of the very stupid behaviour of abs_path()
 176  from the Cwd module: This function is just able to detect the absolute path of
 177  directories.
 178  Hard links are not affected by this, because it is not possible to detect them
 179  (at least I don't know how to detect them).
 180
 181  Root directory must not be a symbolic link:
 182  -------------------------------------------
 183  Now, the root directory must not be a symbolic link.
 184  Sorry for this, I really would have liked to allow the root directory to be a
 185  symbolic link, but if I would allow this, Dev-Editor would not be able to
 186  create files in the root directory. I'm looking for an alternative...
 187
 188  Use Greenwich Mean Time:
 189  ------------------------
 190  You may now use Greenwich Mean Time (GMT/UTC) in dates instead of the local
 191  time.
 192  I don't know if anyone needs this, but it could be useful.
 193
 194  Handle errors produced by File::UseList:
 195  ----------------------------------------
 196  - Check if unlocking of the list of files in use was successful
 197  - Check if a file could be successfully added to the list of files in use
 198  - Check if a file could be successfully removed from the list of files in use
 199
 200  Saving to non-existing files:
 201  -----------------------------
 202  The file saving process was aborted if the user wanted to write text data using
 203  the edit function into a file that does not exists.
 204  The reason was that Dev-Editor thought that this non-existing file was a binary
 205  file.
 206
 207  Template class updated:
 208  -----------------------
 209  The template class was updated to version 1.4.
 210  This fixes the problem of the infinitive loops produced by incorrectly nested
 211  {IF} blocks.
 212
 213  Small changes:
 214  --------------
 215  - Files locked with the flock() function are now unlocked by the close()
 216    function due to security reasons (see
 217    http://forum.de.selfhtml.org/?t=101375&m=622582)
 218  - Changed the names of two error messages:
 219    dircopy -> dir_copy
 220    editdir -> dir_edit
 221  - Fixed various small errors in some template files
 222  - The regular expression used by file_name() and upper_path() to detect Windows
 223    drive letters was not case-insensitive
 224
 225 New in version 2.3 (2005-01-08)
 226 -------------------------------
 227
 228  Filter directory listing:
 229  -------------------------
 230  Dev-Editor is now able to filter the directory listing using DOS-style
 231  wildcards.
 232  I think that is a little bit incomplete, Dev-Editor should be able to
 233  "remember" the filter wildcard during the actions.
 234  The code for parsing DOS-style wildcards is from the File::DosGlob module by
 235  Gurusamy Sarathy.
 236
 237  flock():
 238  --------
 239  Dev-Editor now uses flock().
 240  flock() is called using a wrapper function which checks if it is really
 241  available.
 242
 243  check_path() broken on Windows:
 244  -------------------------------
 245  On Windows systems the check_path() routine was heavily broken (this routine
 246  checks if someone tries to access a path above the virtual root directory). It
 247  was possible to access files above the root directory by accessing a path with
 248  "..." or "...." or something like that as the last path component. This bug was
 249  caused by the rewrite of check_path() in Dev-Editor 2.2.
 250
 251  "." or ".." as end of a path:
 252  -----------------------------
 253  If you enter a path with "." or ".." as the last path component, Dev-Editor
 254  showed a really strange behaviour by allowing to enter a path like
 255  "something/." or "something/..". This was also caused by the (poor) rewrite of
 256  check_path(). The problem is fixed now.
 257
 258  Paths beginning with "/../" caused problems:
 259  --------------------------------------------
 260  When composing the temporary virtual path for a new file, don't call
 261  clean_path(). It is unnecessary and it also caused a problem if this path would
 262  begin with /../, because on UNIX systems, canonpath() removes /../ at the
 263  beginning of a path. So if a user wanted to create the file /../file.ext (but
 264  he wasn't allowed to), he created /file.ext.
 265
 266  Deny changing file properties in some cases:
 267  --------------------------------------------
 268  - Do not allow to change the properties of the root directory
 269  - Do not allow to change the properties of a file in use
 270
 271  Deny overwriting files:
 272  -----------------------
 273  - While processing a file upload, check if the user wants to replace a
 274    directory or overwrite a write-protected file
 275  - If the user wants to copy or rename a file, check if he wants to overwrite a
 276    write-protected file
 277  - Do not allow to upload a file if a file with the same virtual name is
 278    currently in use
 279
 280  Validate file uploads:
 281  ----------------------
 282  Dev-Editor now tries to validate a file upload by checking the handle created
 283  by the CGI module.
 284
 285  Improved configuration file parser:
 286  -----------------------------------
 287  - The parser now ignores lines like that:
 288       = Value
 289    Such lines could lead to properties with empty keys in the configuration
 290    hash.
 291  - Allow configuration options with empty values
 292  - If a option is defined twice, the line number of the second one is shown in
 293    the error message
 294
 295  Output changes:
 296  ---------------
 297  - More encoding of HTML entities
 298  - In directory listing, the "Edit" link of files in use were not greyed (very
 299    nasty)
 300  - Show the name of the lock file in error messages even if it has not been
 301    defined in the configuration file
 302
 303  Small internal changes:
 304  -----------------------
 305  - The file saving process is now completely centralized in File::Access
 306  - When generating a redirection header, check if we really have to create a
 307    query string
 308  - Fixed a bug occuring if the "curdir" CGI parameter had no trailing slash and
 309    the "newfile" parameter had no leading slash
 310  - Dev-Editor now takes more care of Windows drive letters
 311  - Trying to increase speed of the script by surrounding static values by single
 312    quotes
 313  - Code cleaning
 314
 315 New in version 2.2a (2004-11-29)
 316 --------------------------------
 317
 318  File uploads did not work:
 319  --------------------------
 320  Dev-Editor normally tests if it has enough permissions to upload a file to a
 321  directory. But the condition was missing and so Dev-Editor always aborted file
 322  uploads and didn't even display the dialogue.
 323
 324 New in version 2.2 (2004-11-27)
 325 -------------------------------
 326
 327  `chgrp` system command and numerical group names:
 328  -------------------------------------------------
 329  When changing the group, Dev-Editor is now using the `chgrp` system command.
 330  This allows to use numerical group names. Before, Dev-Editor handled numerical
 331  values as group IDs.
 332
 333  Checking root directory:
 334  ------------------------
 335  Dev-Editor now checks if the root directory exists and if it may be accessed.
 336  This fixed also bug where it was possible to access the physical root directory
 337  if Dev-Editor could not enter the virtual root directory.
 338
 339  Checking directory permissions:
 340  -------------------------------
 341  Dev-Editor does some simple checks of directory permissions now:
 342  - Inaccessible directories are greyed in directory listing. You cannot access
 343    them, but the actions are not disabled, because they may work.
 344  - Actions needing write access to a directory are aborted if Dev-Editor has no
 345    write access.
 346
 347  Access a directory structure similar to the root directory:
 348  -----------------------------------------------------------
 349  The path the user wants to access must now BEGIN with the root directory. The
 350  old check made it possible to access a directory structure outside the root
 351  directory similar to the root directory.
 352
 353  Changing mode of a directory with mode 000:
 354  -------------------------------------------
 355  It was not possible to change the mode of a directory with mode 000.
 356
 357  Upload only to directories:
 358  ---------------------------
 359  Dev-Editor now checks if the user really uploads a file to a directory.
 360
 361  Improved About dialogue:
 362  ------------------------
 363  - Dev-Editor now only shows the main group ID of the process user.
 364  - Dev-Editor also shows the current umask of the process.
 365  - Special chars in most values are now encoded to entities.
 366
 367  Added <label> tags:
 368  -------------------
 369  For a better usability in some browsers, I added <label> tags for the
 370  checkboxes and radio buttons in file edit and file upload dialogue.
 371
 372  Directory links in error messages:
 373  ----------------------------------
 374  Some error messages generated by the main program now contain a link to the
 375  root directory.
 376
 377  Bugs in HTML generation:
 378  ------------------------
 379  - If Dev-Editor could not read a directory, it did neither display an error
 380    message nor a directory link.
 381  - Some error messages had problems with {DIR} variables. Thus the variable in
 382    error.htm which will be replaced by a back link is now called "{BACK}".
 383  - When viewing a file, Dev-Editor inserts the contents of the file into the
 384    viewfile.htm template file AFTER parsing the "editable" {IF}-block, because
 385    Dev-Editor showed a very ugly behaviour when viewing this template file.
 386
 387  Code cleaning:
 388  --------------
 389  I tried to clean the source code of Dev-Editor a little bit. Some parts of the
 390  code were optimized.
 391
 392 New in version 2.1a (2004-10-22)
 393 --------------------------------
 394
 395  Changed file saving error handling:
 396  -----------------------------------
 397  Now we already unlock the file saving process, because if an error occurs
 398  during this process, the file keeps locked.
 399  This is not a perfect solution, there are still problems. I have to figure out
 400  another one.
 401
 402 New in version 2.1 (2004-10-14)
 403 -------------------------------
 404
 405  Overwrite files during file upload:
 406  -----------------------------------
 407  In file upload dialogue, there is a new checkbox which allows to overwrite
 408  files during file upload if they already exist.
 409
 410  Improved file saving:
 411  ---------------------
 412  The process of file saving has been improved:
 413  - Saving even works if the file has to be created first.
 414  - Dev-Editor is now checking if the user wants to write text data into a binary
 415    file.
 416  - If the user just entered spaces as filename (detection works for other
 417    commands using the "newfile" CGI parameter too), we use the original
 418    filename.
 419
 420  Don't copy a directory:
 421  -----------------------
 422  Dev-Editor now denies copying a directory.
 423
 424  Check before manually unlocking:
 425  --------------------------------
 426  Dev-Editor now checks if the file is really locked before displaying the
 427  dialogue for manually unlocking a file. If it is not locked, Dev-Editor returns
 428  to directory view. Dev-Editor also behaves in this way if it is trying to
 429  unlock a file.
 430
 431  Wrong error messages:
 432  ---------------------
 433  Something definitely went wrong when I remade the copy and the rename
 434  functions: They printed a wrong error message if the destination already
 435  existed and if it was a file.
 436
 437 New in version 2.0 (2004-08-10)
 438 -------------------------------
 439
 440  File uploads:
 441  -------------
 442  Dev-Editor is now able to process HTTP file uploads. The files may be
 443  transferred in ASCII or binary mode (similar to FTP).
 444
 445  Change mode and group:
 446  ----------------------
 447  Dev-Editor is now able to change the mode and the group of a file or a
 448  directory.
 449
 450  HTTPS support and non-default ports:
 451  ------------------------------------
 452  Dev-Editor is now able to detect a HTTPS connection and if the web server
 453  doesn't listen on the default ports (necessary for reloading Dev-Editor).
 454
 455  Do not allow removing or renaming the root directory:
 456  -----------------------------------------------------
 457  Dev-Editor now denies removing or renaming the root directory.
 458
 459  Renaming files outside the root directory:
 460  ------------------------------------------
 461  There was a bug which caused Dev-Editor not to rename files outside the root
 462  directory if they already exist.
 463
 464  Improved file editing:
 465  ----------------------
 466  When the user wants to save an edited file using a different file name,
 467  Dev-Editor now unlocks the original file and checks if a file with this
 468  different name already exists and if it is locked.
 469
 470  Improved file creating:
 471  -----------------------
 472  The routine which creates empty files had a race condition which could set
 473  files to 0 if they already exist.
 474
 475  Maximum size for files:
 476  -----------------------
 477  The administrator may now define a maximum size for files in the main
 478  configuration file. If the user wants to view or edit a file larger than this
 479  defined size, Dev-Editor denies file access (but the file can still be copied,
 480  renamed or removed).
 481
 482  Form for creating new files or directories:
 483  -------------------------------------------
 484  In directory listing, when clicking on the buttons next to the fields for
 485  creating new files and directories without entering a file or directory name,
 486  the user got an error message which is a little bit strange.
 487  Now, the user will see a form for creating new files or directories.
 488
 489  Newlines are converted while reading:
 490  -------------------------------------
 491  Whenever Dev-Editor now reads a file for output, it converts any line separator
 492  to the system specific one.
 493
 494  Case-insensitive commands:
 495  --------------------------
 496  The commands are now case-insensitive, so the command "ShOw" is the same as
 497  "show".
 498
 499  About screen:
 500  -------------
 501  There is now a small "About" screen which shows some more or less useful
 502  information about Dev-Editor and the system.
 503
 504  Improvements for user interface:
 505  --------------------------------
 506  Made a lot of improvements for the user interface:
 507  - The directory listing is now built using tables.
 508  - When editing a file and the user wants to save a file using a different file
 509    name, the checkbox for saving the file using a different file name is
 510    activated using JavaScript.
 511  - In directory listing or when viewing a file, there is a new field for quickly
 512    jumping to a file or to a directory.
 513  - Separated "Work with directory" and "Work with file" into different options
 514    in directory listing ("Copy", "Rename", "Delete", "Unlock"). The options also
 515    have their own dialogues.
 516  - In directory listing, there is a new link for viewing a file or a directory
 517    in the browser.
 518  - When viewing a file and if the file is editable, there is a new link to edit
 519    this  file.
 520  - Files and directories in directory listing are now sorted case-insensitively.
 521
 522  Configuration files:
 523  --------------------
 524  The settings of Dev-Editor are now stored in extern configuration files: There
 525  is one file for general settings, one for the error messages and one for the
 526  paths to the template files.
 527
 528  Templates:
 529  ----------
 530  The output of Dev-Editor is now controlled by template files. The source code
 531  became much cleaner :-)
 532
 533 New in version 1.2 (2003-12-29)
 534 -------------------------------
 535
 536  Removing directories:
 537  ---------------------
 538  Dev-Editor is now able to completely remove a directory.
 539
 540  "Work with directories":
 541  ------------------------
 542  In directory listing, next do a directory, there is a new link called "Work
 543  with directory". When you select this link, you get a form to remove or
 544  rename/move the directory.
 545  Additionally, the link "Do other stuff" was renamed to "Work with file".
 546
 547  Overwriting existing files:
 548  ---------------------------
 549  If you want to copy a file, and the destination file already exists, you will
 550  be asked to overwrite the file. If the destination points to a directory,
 551  copying will be aborted completely.
 552  If you want to rename a file or a directory, and the destination file already
 553  exists, you will be asked to overwrite the file. If the destination points to a
 554  directory, renaming will be aborted completely.
 555
 556  Confirmation for removing files:
 557  --------------------------------
 558  If you want to remove a file, a confirmation dialog will be displayed first.
 559
 560  Fixed open() calls:
 561  -------------------
 562  It seems that some systems don't support the FILEHANDLE,MODE,FILENAME version
 563  of open(). Now we don't use it any more.
 564
 565  Default permissions for mkdir():
 566  --------------------------------
 567  Set the permissions for mkdir() to 0777. I thought it is optional (as described
 568  in "perlfunc"), but some systems need it.
 569
 570 New in version 1.1 (2003-11-15)
 571 -------------------------------
 572
 573  Newlines are converted:
 574  -----------------------
 575  Any line seperator will now be converted to the system specific line seperator
 576  if you save a text file.
 577
 578  File permissions are checked:
 579  -----------------------------
 580  Dev-Editor now runs some simple checks on the file permissions when it creates
 581  a directory listing, tries to view or edit a file and when it copies a file.
 582
 583  Tool tips for file status:
 584  --------------------------
 585  In directory listing, when a file cannot be viewed or edited, a tool tip on the
 586  "View" or "Edit" link will show the reason why it is so.
 587
 588  File permissions are saved:
 589  ---------------------------
 590  When the user saves a text file, the file permissions were destroyed. The
 591  reason was that a temporary file was used, which was renamed to the originally
 592  file. Now this is fixed, but if saving of the file now fails, the file could be
 593  damaged...
 594
 595  Links in error messages:
 596  ------------------------
 597  Some error messages now contain a link to go back to the directory containing
 598  the file which caused the error.
 599
 600  Typos fixed:
 601  ------------
 602  There were a lot of typos in the output, the comments and the ReadMe file.
 603
 604  Dates fixed:
 605  ------------
 606  The dates of the last modification in the head comment of the files had the
 607  wrong format. They had the format MM-DD-YYYY, but they should have YYYY-MM-DD.
 608  Sorry, that was VERY embarassing...
 609
 610 New in version 1.0 (2003-10-08)
 611 -------------------------------
 612
 613  First public release:
 614  ---------------------
 615  This is the first public release of Dev-Editor.
 616
 617 ------------------------------------------------
