CHANGELOG

   1 Change Log for Dev-Editor
   2 =========================
   3
   4 Version 3.1 (2009-05-12):
   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  Remote name for uploaded files:
  18  -------------------------------
  19  When uploading a file, you can now specify a name for the file on the server.
  20
  21  Prefilled form fields:
  22  ----------------------
  23  If you want to copy or rename/move a file or a directory or save a file using
  24  a different name, the form field for the new filename is prefilled with the
  25  old one. Additionally, the entered path is no more relative to the directory
  26  of the original file.
  27
  28  Hide dot files:
  29  ---------------
  30  When the new configuration option "hide_dot_files" is set to 1, every file or
  31  directory beginning with a "." is not shown in the directory listing. But you
  32  can still access the file / directory by typing its name into the "Go to
  33  directory/file" box.
  34  This option is also available in the user-dependent configuration.
  35
  36  Copyright note:
  37  ---------------
  38  In the header of each file, there is a now a copyright note and a reference to
  39  the Artistic License.
  40
  41  Template class updated:
  42  -----------------------
  43  The template class was updated to version 2.0.
  44
  45 Version 3.0.1 (2005-11-10):
  46 ===========================
  47
  48  Accessing files above the virtual root directory:
  49  -------------------------------------------------
  50  It was possible to access files and directories above the virtual root
  51  directory beginning with the same string as the root directory.
  52  For example:
  53  If your root directory is "/var/www/user1" it was possible to access
  54  "/var/www/user10", "/var/www/user11" and so on.
  55
  56 Version 3.0 (2005-10-18):
  57 =========================
  58
  59  Editing function changed:
  60  -------------------------
  61  - The concept of locking the file for other users before editing it is not very
  62    good, causes some problems and makes it difficult to add new features. So I
  63    decided to remove it.
  64  - When Dev-Editor shows the form for editing a file, it calculates the MD5
  65    checksum and places it in the editing form. Before saving the file, the MD5
  66    checksum is calculated again and compared to the submitted one. If the two
  67    sums don't match, Dev-Editor does not save the file and shows the editing
  68    form.
  69  - In the edit dialogue, there is also a new submit button allowing to continue
  70    editing the file after saving it.
  71  - Removed the possibility of encoding ISO-8859-1 HTML entities when saving a
  72    file. I don't know if anybody used this function.
  73
  74  Copy directories:
  75  -----------------
  76  Dev-Editor is now able to copy a directory.
  77
  78  Forbid file access:
  79  -------------------
  80  The administrator may now define a list of files the user is not allowed to
  81  access.
  82
  83  Individual configuration:
  84  -------------------------
  85  Now, Dev-Editor is able to switch some configuration values depending on the
  86  current HTTP Auth user.
  87  This is controlled by a separate configuration file containing sections like
  88  Windows INI files (thus the configuration file parser is now able to parse
  89  files containing sections in square brackets).
  90  You may overwrite the following configuration values:
  91  - fileroot
  92  - httproot
  93  - forbidden (you may also clear the default "forbidden" list)
  94
  95  Configuration files renamed:
  96  ----------------------------
  97  The extension of the configuration files is "conf" now.
  98
  99  Names of error messages changed:
 100  --------------------------------
 101  I changed the names of some error messages:
 102  binary        -> binary_file
 103  cmd_unknown   -> command_unknown
 104  dir_read_fail -> dir_read_failed
 105  create_ar     -> create_above_root
 106  not_exist     -> not_found
 107
 108  File names containing a "+" sign:
 109  ---------------------------------
 110  If a file name contained a "+" sign, Dev-Editor was sometimes not able to
 111  access the file, because the "+" was interpreted as a space.
 112
 113  Check octal numbers:
 114  --------------------
 115  Before changing the permissions of a file, Dev-Editor now checks if the user
 116  entered a valid octal number.
 117
 118  Encoding of HTML entities:
 119  --------------------------
 120  - All HTML in output is now properly encoded
 121  - HTML::Entities is a little bit slow and does currently not support very much
 122    encodings. Now, we just encode the HTML control characters (<, >, & and ").
 123    This also means that Dev-Editor now does not require any CPAN module.
 124
 125  Template class updated:
 126  -----------------------
 127  The template class was updated to version 1.5.
 128
 129  Small changes:
 130  --------------
 131  - Don't show the "Copy" link if a file is not readable
 132  - Added checkboxes in the "Copy" and "Rename" dialogues for immediately
 133    overwriting an existing file
 134  - Preserve the directory listing filter if the user changes the directory using
 135    the input field at the bottom of the directory listing
 136
 137 New in version 2.3.2 (2005-04-23)
 138 ---------------------------------
 139
 140  Copying a file out of a directory:
 141  ----------------------------------
 142  Fixed a really strange bug occuring only on Windows systems.
 143  Dev-Editor was not able to copy (or move) a file out of a directory if the
 144  path, the user entered in the corresponding dialogue, was beginning with "../".
 145
 146  Empty root directory causes incomplete HTML table:
 147  --------------------------------------------------
 148  Dev-Editor now does not create an incomplete HTML table if the root directory
 149  is completely empty or no files are matching against the current wildcard.
 150
 151  move() instead of rename():
 152  ---------------------------
 153  Dev-Editor now uses the move() function from the File::Copy module to move or
 154  rename files and directories. move() is more reliable than the rename()
 155  function.
 156
 157  No error message if reading of a directory failed:
 158  --------------------------------------------------
 159  If reading of a directory failed, no error message was shown. I thought this
 160  bug was fixed...
 161
 162  Template class updated:
 163  -----------------------
 164  The template class was updated to version 1.4a.
 165
 166 New in version 2.3.1 (2005-02-19)
 167 ---------------------------------
 168
 169  Handling of symbolic links changed:
 170  -----------------------------------
 171  For security reasons, I completely changed the handling of symbolic links:
 172  Symbolic links are now treated as files, no matter where they point to. The
 173  user is just allowed to see the path where the link points to, he is allowed to
 174  delete the link, to rename it and to overwrite it by renaming an other file.
 175  Nothing else is allowed.
 176  Accessing a symbolic link pointing to a directory caused also a very strange
 177  effect: It was possible to access this directory, but you could not access
 178  the objects in it.
 179  I had to do it in this way because of the very stupid behaviour of abs_path()
 180  from the Cwd module: This function is just able to detect the absolute path of
 181  directories.
 182  Hard links are not affected by this, because it is not possible to detect them
 183  (at least I don't know how to detect them).
 184
 185  Root directory must not be a symbolic link:
 186  -------------------------------------------
 187  Now, the root directory must not be a symbolic link.
 188  Sorry for this, I really would have liked to allow the root directory to be a
 189  symbolic link, but if I would allow this, Dev-Editor would not be able to
 190  create files in the root directory. I'm looking for an alternative...
 191
 192  Use Greenwich Mean Time:
 193  ------------------------
 194  You may now use Greenwich Mean Time (GMT/UTC) in dates instead of the local
 195  time.
 196  I don't know if anyone needs this, but it could be useful.
 197
 198  Handle errors produced by File::UseList:
 199  ----------------------------------------
 200  - Check if unlocking of the list of files in use was successful
 201  - Check if a file could be successfully added to the list of files in use
 202  - Check if a file could be successfully removed from the list of files in use
 203
 204  Saving to non-existing files:
 205  -----------------------------
 206  The file saving process was aborted if the user wanted to write text data using
 207  the edit function into a file that does not exists.
 208  The reason was that Dev-Editor thought that this non-existing file was a binary
 209  file.
 210
 211  Template class updated:
 212  -----------------------
 213  The template class was updated to version 1.4.
 214  This fixes the problem of the infinitive loops produced by incorrectly nested
 215  {IF} blocks.
 216
 217  Small changes:
 218  --------------
 219  - Files locked with the flock() function are now unlocked by the close()
 220    function due to security reasons (see
 221    http://forum.de.selfhtml.org/?t=101375&m=622582)
 222  - Changed the names of two error messages:
 223    dircopy -> dir_copy
 224    editdir -> dir_edit
 225  - Fixed various small errors in some template files
 226  - The regular expression used by file_name() and upper_path() to detect Windows
 227    drive letters was not case-insensitive
 228
 229 New in version 2.3 (2005-01-08)
 230 -------------------------------
 231
 232  Filter directory listing:
 233  -------------------------
 234  Dev-Editor is now able to filter the directory listing using DOS-style
 235  wildcards.
 236  I think that is a little bit incomplete, Dev-Editor should be able to
 237  "remember" the filter wildcard during the actions.
 238  The code for parsing DOS-style wildcards is from the File::DosGlob module by
 239  Gurusamy Sarathy.
 240
 241  flock():
 242  --------
 243  Dev-Editor now uses flock().
 244  flock() is called using a wrapper function which checks if it is really
 245  available.
 246
 247  check_path() broken on Windows:
 248  -------------------------------
 249  On Windows systems the check_path() routine was heavily broken (this routine
 250  checks if someone tries to access a path above the virtual root directory). It
 251  was possible to access files above the root directory by accessing a path with
 252  "..." or "...." or something like that as the last path component. This bug was
 253  caused by the rewrite of check_path() in Dev-Editor 2.2.
 254
 255  "." or ".." as end of a path:
 256  -----------------------------
 257  If you enter a path with "." or ".." as the last path component, Dev-Editor
 258  showed a really strange behaviour by allowing to enter a path like
 259  "something/." or "something/..". This was also caused by the (poor) rewrite of
 260  check_path(). The problem is fixed now.
 261
 262  Paths beginning with "/../" caused problems:
 263  --------------------------------------------
 264  When composing the temporary virtual path for a new file, don't call
 265  clean_path(). It is unnecessary and it also caused a problem if this path would
 266  begin with /../, because on UNIX systems, canonpath() removes /../ at the
 267  beginning of a path. So if a user wanted to create the file /../file.ext (but
 268  he wasn't allowed to), he created /file.ext.
 269
 270  Deny changing file properties in some cases:
 271  --------------------------------------------
 272  - Do not allow to change the properties of the root directory
 273  - Do not allow to change the properties of a file in use
 274
 275  Deny overwriting files:
 276  -----------------------
 277  - While processing a file upload, check if the user wants to replace a
 278    directory or overwrite a write-protected file
 279  - If the user wants to copy or rename a file, check if he wants to overwrite a
 280    write-protected file
 281  - Do not allow to upload a file if a file with the same virtual name is
 282    currently in use
 283
 284  Validate file uploads:
 285  ----------------------
 286  Dev-Editor now tries to validate a file upload by checking the handle created
 287  by the CGI module.
 288
 289  Improved configuration file parser:
 290  -----------------------------------
 291  - The parser now ignores lines like that:
 292       = Value
 293    Such lines could lead to properties with empty keys in the configuration
 294    hash.
 295  - Allow configuration options with empty values
 296  - If a option is defined twice, the line number of the second one is shown in
 297    the error message
 298
 299  Output changes:
 300  ---------------
 301  - More encoding of HTML entities
 302  - In directory listing, the "Edit" link of files in use were not greyed (very
 303    nasty)
 304  - Show the name of the lock file in error messages even if it has not been
 305    defined in the configuration file
 306
 307  Small internal changes:
 308  -----------------------
 309  - The file saving process is now completely centralized in File::Access
 310  - When generating a redirection header, check if we really have to create a
 311    query string
 312  - Fixed a bug occuring if the "curdir" CGI parameter had no trailing slash and
 313    the "newfile" parameter had no leading slash
 314  - Dev-Editor now takes more care of Windows drive letters
 315  - Trying to increase speed of the script by surrounding static values by single
 316    quotes
 317  - Code cleaning
 318
 319 New in version 2.2a (2004-11-29)
 320 --------------------------------
 321
 322  File uploads did not work:
 323  --------------------------
 324  Dev-Editor normally tests if it has enough permissions to upload a file to a
 325  directory. But the condition was missing and so Dev-Editor always aborted file
 326  uploads and didn't even display the dialogue.
 327
 328 New in version 2.2 (2004-11-27)
 329 -------------------------------
 330
 331  `chgrp` system command and numerical group names:
 332  -------------------------------------------------
 333  When changing the group, Dev-Editor is now using the `chgrp` system command.
 334  This allows to use numerical group names. Before, Dev-Editor handled numerical
 335  values as group IDs.
 336
 337  Checking root directory:
 338  ------------------------
 339  Dev-Editor now checks if the root directory exists and if it may be accessed.
 340  This fixed also bug where it was possible to access the physical root directory
 341  if Dev-Editor could not enter the virtual root directory.
 342
 343  Checking directory permissions:
 344  -------------------------------
 345  Dev-Editor does some simple checks of directory permissions now:
 346  - Inaccessible directories are greyed in directory listing. You cannot access
 347    them, but the actions are not disabled, because they may work.
 348  - Actions needing write access to a directory are aborted if Dev-Editor has no
 349    write access.
 350
 351  Access a directory structure similar to the root directory:
 352  -----------------------------------------------------------
 353  The path the user wants to access must now BEGIN with the root directory. The
 354  old check made it possible to access a directory structure outside the root
 355  directory similar to the root directory.
 356
 357  Changing mode of a directory with mode 000:
 358  -------------------------------------------
 359  It was not possible to change the mode of a directory with mode 000.
 360
 361  Upload only to directories:
 362  ---------------------------
 363  Dev-Editor now checks if the user really uploads a file to a directory.
 364
 365  Improved About dialogue:
 366  ------------------------
 367  - Dev-Editor now only shows the main group ID of the process user.
 368  - Dev-Editor also shows the current umask of the process.
 369  - Special chars in most values are now encoded to entities.
 370
 371  Added <label> tags:
 372  -------------------
 373  For a better usability in some browsers, I added <label> tags for the
 374  checkboxes and radio buttons in file edit and file upload dialogue.
 375
 376  Directory links in error messages:
 377  ----------------------------------
 378  Some error messages generated by the main program now contain a link to the
 379  root directory.
 380
 381  Bugs in HTML generation:
 382  ------------------------
 383  - If Dev-Editor could not read a directory, it did neither display an error
 384    message nor a directory link.
 385  - Some error messages had problems with {DIR} variables. Thus the variable in
 386    error.htm which will be replaced by a back link is now called "{BACK}".
 387  - When viewing a file, Dev-Editor inserts the contents of the file into the
 388    viewfile.htm template file AFTER parsing the "editable" {IF}-block, because
 389    Dev-Editor showed a very ugly behaviour when viewing this template file.
 390
 391  Code cleaning:
 392  --------------
 393  I tried to clean the source code of Dev-Editor a little bit. Some parts of the
 394  code were optimized.
 395
 396 New in version 2.1a (2004-10-22)
 397 --------------------------------
 398
 399  Changed file saving error handling:
 400  -----------------------------------
 401  Now we already unlock the file saving process, because if an error occurs
 402  during this process, the file keeps locked.
 403  This is not a perfect solution, there are still problems. I have to figure out
 404  another one.
 405
 406 New in version 2.1 (2004-10-14)
 407 -------------------------------
 408
 409  Overwrite files during file upload:
 410  -----------------------------------
 411  In file upload dialogue, there is a new checkbox which allows to overwrite
 412  files during file upload if they already exist.
 413
 414  Improved file saving:
 415  ---------------------
 416  The process of file saving has been improved:
 417  - Saving even works if the file has to be created first.
 418  - Dev-Editor is now checking if the user wants to write text data into a binary
 419    file.
 420  - If the user just entered spaces as filename (detection works for other
 421    commands using the "newfile" CGI parameter too), we use the original
 422    filename.
 423
 424  Don't copy a directory:
 425  -----------------------
 426  Dev-Editor now denies copying a directory.
 427
 428  Check before manually unlocking:
 429  --------------------------------
 430  Dev-Editor now checks if the file is really locked before displaying the
 431  dialogue for manually unlocking a file. If it is not locked, Dev-Editor returns
 432  to directory view. Dev-Editor also behaves in this way if it is trying to
 433  unlock a file.
 434
 435  Wrong error messages:
 436  ---------------------
 437  Something definitely went wrong when I remade the copy and the rename
 438  functions: They printed a wrong error message if the destination already
 439  existed and if it was a file.
 440
 441 New in version 2.0 (2004-08-10)
 442 -------------------------------
 443
 444  File uploads:
 445  -------------
 446  Dev-Editor is now able to process HTTP file uploads. The files may be
 447  transferred in ASCII or binary mode (similar to FTP).
 448
 449  Change mode and group:
 450  ----------------------
 451  Dev-Editor is now able to change the mode and the group of a file or a
 452  directory.
 453
 454  HTTPS support and non-default ports:
 455  ------------------------------------
 456  Dev-Editor is now able to detect a HTTPS connection and if the web server
 457  doesn't listen on the default ports (necessary for reloading Dev-Editor).
 458
 459  Do not allow removing or renaming the root directory:
 460  -----------------------------------------------------
 461  Dev-Editor now denies removing or renaming the root directory.
 462
 463  Renaming files outside the root directory:
 464  ------------------------------------------
 465  There was a bug which caused Dev-Editor not to rename files outside the root
 466  directory if they already exist.
 467
 468  Improved file editing:
 469  ----------------------
 470  When the user wants to save an edited file using a different file name,
 471  Dev-Editor now unlocks the original file and checks if a file with this
 472  different name already exists and if it is locked.
 473
 474  Improved file creating:
 475  -----------------------
 476  The routine which creates empty files had a race condition which could set
 477  files to 0 if they already exist.
 478
 479  Maximum size for files:
 480  -----------------------
 481  The administrator may now define a maximum size for files in the main
 482  configuration file. If the user wants to view or edit a file larger than this
 483  defined size, Dev-Editor denies file access (but the file can still be copied,
 484  renamed or removed).
 485
 486  Form for creating new files or directories:
 487  -------------------------------------------
 488  In directory listing, when clicking on the buttons next to the fields for
 489  creating new files and directories without entering a file or directory name,
 490  the user got an error message which is a little bit strange.
 491  Now, the user will see a form for creating new files or directories.
 492
 493  Newlines are converted while reading:
 494  -------------------------------------
 495  Whenever Dev-Editor now reads a file for output, it converts any line separator
 496  to the system specific one.
 497
 498  Case-insensitive commands:
 499  --------------------------
 500  The commands are now case-insensitive, so the command "ShOw" is the same as
 501  "show".
 502
 503  About screen:
 504  -------------
 505  There is now a small "About" screen which shows some more or less useful
 506  information about Dev-Editor and the system.
 507
 508  Improvements for user interface:
 509  --------------------------------
 510  Made a lot of improvements for the user interface:
 511  - The directory listing is now built using tables.
 512  - When editing a file and the user wants to save a file using a different file
 513    name, the checkbox for saving the file using a different file name is
 514    activated using JavaScript.
 515  - In directory listing or when viewing a file, there is a new field for quickly
 516    jumping to a file or to a directory.
 517  - Separated "Work with directory" and "Work with file" into different options
 518    in directory listing ("Copy", "Rename", "Delete", "Unlock"). The options also
 519    have their own dialogues.
 520  - In directory listing, there is a new link for viewing a file or a directory
 521    in the browser.
 522  - When viewing a file and if the file is editable, there is a new link to edit
 523    this  file.
 524  - Files and directories in directory listing are now sorted case-insensitively.
 525
 526  Configuration files:
 527  --------------------
 528  The settings of Dev-Editor are now stored in extern configuration files: There
 529  is one file for general settings, one for the error messages and one for the
 530  paths to the template files.
 531
 532  Templates:
 533  ----------
 534  The output of Dev-Editor is now controlled by template files. The source code
 535  became much cleaner :-)
 536
 537 New in version 1.2 (2003-12-29)
 538 -------------------------------
 539
 540  Removing directories:
 541  ---------------------
 542  Dev-Editor is now able to completely remove a directory.
 543
 544  "Work with directories":
 545  ------------------------
 546  In directory listing, next do a directory, there is a new link called "Work
 547  with directory". When you select this link, you get a form to remove or
 548  rename/move the directory.
 549  Additionally, the link "Do other stuff" was renamed to "Work with file".
 550
 551  Overwriting existing files:
 552  ---------------------------
 553  If you want to copy a file, and the destination file already exists, you will
 554  be asked to overwrite the file. If the destination points to a directory,
 555  copying will be aborted completely.
 556  If you want to rename a file or a directory, and the destination file already
 557  exists, you will be asked to overwrite the file. If the destination points to a
 558  directory, renaming will be aborted completely.
 559
 560  Confirmation for removing files:
 561  --------------------------------
 562  If you want to remove a file, a confirmation dialog will be displayed first.
 563
 564  Fixed open() calls:
 565  -------------------
 566  It seems that some systems don't support the FILEHANDLE,MODE,FILENAME version
 567  of open(). Now we don't use it any more.
 568
 569  Default permissions for mkdir():
 570  --------------------------------
 571  Set the permissions for mkdir() to 0777. I thought it is optional (as described
 572  in "perlfunc"), but some systems need it.
 573
 574 New in version 1.1 (2003-11-15)
 575 -------------------------------
 576
 577  Newlines are converted:
 578  -----------------------
 579  Any line seperator will now be converted to the system specific line seperator
 580  if you save a text file.
 581
 582  File permissions are checked:
 583  -----------------------------
 584  Dev-Editor now runs some simple checks on the file permissions when it creates
 585  a directory listing, tries to view or edit a file and when it copies a file.
 586
 587  Tool tips for file status:
 588  --------------------------
 589  In directory listing, when a file cannot be viewed or edited, a tool tip on the
 590  "View" or "Edit" link will show the reason why it is so.
 591
 592  File permissions are saved:
 593  ---------------------------
 594  When the user saves a text file, the file permissions were destroyed. The
 595  reason was that a temporary file was used, which was renamed to the originally
 596  file. Now this is fixed, but if saving of the file now fails, the file could be
 597  damaged...
 598
 599  Links in error messages:
 600  ------------------------
 601  Some error messages now contain a link to go back to the directory containing
 602  the file which caused the error.
 603
 604  Typos fixed:
 605  ------------
 606  There were a lot of typos in the output, the comments and the ReadMe file.
 607
 608  Dates fixed:
 609  ------------
 610  The dates of the last modification in the head comment of the files had the
 611  wrong format. They had the format MM-DD-YYYY, but they should have YYYY-MM-DD.
 612  Sorry, that was VERY embarassing...
 613
 614 New in version 1.0 (2003-10-08)
 615 -------------------------------
 616
 617  First public release:
 618  ---------------------
 619  This is the first public release of Dev-Editor.
 620
 621 ------------------------------------------------
