CHANGELOG

   1 Change Log for Dev-Editor
   2 =========================
   3
   4 Version 3.2 (201x-xx-xx):
   5 =========================
   6
   7  Unpacking archive files:
   8  ------------------------
   9  Dev-Editor is now able to unpack some types archive files. You may unpack
  10  archive files in directory listing or immediately after uploading it to the
  11  server.
  12  To achieve this, Dev-Editor relies on the Perl module Archive::Extract (core
  13  module since 5.10, I guess).
  14
  15  Disabling commands:
  16  -------------------
  17  Added new configuration option "disable_commands" for disabling commands of
  18  Dev-Editor.
  19
  20  Start directory:
  21  ----------------
  22  Added new configuration option "startdir" which defines the default directory
  23  instead of "/".
  24
  25  HTTP download:
  26  --------------
  27  You may now execute a HTTP download of a file.
  28
  29  Small changes:
  30  --------------
  31  - Added a checkbox for editing a file after creating it.
  32  - Changed the colour scheme in directory listing.
  33  - In directory listing, added links for (un-)selecting aa files.
  34
  35 Version 3.1 (2009-05-12):
  36 =========================
  37
  38  Removing multiple files:
  39  ------------------------
  40  In the directory listing, there are now checkboxes for selecting files and a
  41  button for removing them.
  42
  43  Better distinction of objects in directory listing:
  44  ---------------------------------------------------
  45  For a better distinction of the objects in directory listing, every second
  46  object has a grey background now.
  47
  48  Remote name for uploaded files:
  49  -------------------------------
  50  When uploading a file, you can now specify a name for the file on the server.
  51
  52  Prefilled form fields:
  53  ----------------------
  54  If you want to copy or rename/move a file or a directory or save a file using
  55  a different name, the form field for the new filename is prefilled with the
  56  old one. Additionally, the entered path is no more relative to the directory
  57  of the original file.
  58
  59  Hide dot files:
  60  ---------------
  61  When the new configuration option "hide_dot_files" is set to 1, every file or
  62  directory beginning with a "." is not shown in the directory listing. But you
  63  can still access the file / directory by typing its name into the "Go to
  64  directory/file" box.
  65  This option is also available in the user-dependent configuration.
  66
  67  Copyright note:
  68  ---------------
  69  In the header of each file, there is a now a copyright note and a reference to
  70  the Artistic License.
  71
  72  Template class updated:
  73  -----------------------
  74  The template class was updated to version 2.0.
  75
  76 Version 3.0.1 (2005-11-10):
  77 ===========================
  78
  79  Accessing files above the virtual root directory:
  80  -------------------------------------------------
  81  It was possible to access files and directories above the virtual root
  82  directory beginning with the same string as the root directory.
  83  For example:
  84  If your root directory is "/var/www/user1" it was possible to access
  85  "/var/www/user10", "/var/www/user11" and so on.
  86
  87 Version 3.0 (2005-10-18):
  88 =========================
  89
  90  Editing function changed:
  91  -------------------------
  92  - The concept of locking the file for other users before editing it is not very
  93    good, causes some problems and makes it difficult to add new features. So I
  94    decided to remove it.
  95  - When Dev-Editor shows the form for editing a file, it calculates the MD5
  96    checksum and places it in the editing form. Before saving the file, the MD5
  97    checksum is calculated again and compared to the submitted one. If the two
  98    sums don't match, Dev-Editor does not save the file and shows the editing
  99    form.
 100  - In the edit dialogue, there is also a new submit button allowing to continue
 101    editing the file after saving it.
 102  - Removed the possibility of encoding ISO-8859-1 HTML entities when saving a
 103    file. I don't know if anybody used this function.
 104
 105  Copy directories:
 106  -----------------
 107  Dev-Editor is now able to copy a directory.
 108
 109  Forbid file access:
 110  -------------------
 111  The administrator may now define a list of files the user is not allowed to
 112  access.
 113
 114  Individual configuration:
 115  -------------------------
 116  Now, Dev-Editor is able to switch some configuration values depending on the
 117  current HTTP Auth user.
 118  This is controlled by a separate configuration file containing sections like
 119  Windows INI files (thus the configuration file parser is now able to parse
 120  files containing sections in square brackets).
 121  You may overwrite the following configuration values:
 122  - fileroot
 123  - httproot
 124  - forbidden (you may also clear the default "forbidden" list)
 125
 126  Configuration files renamed:
 127  ----------------------------
 128  The extension of the configuration files is "conf" now.
 129
 130  Names of error messages changed:
 131  --------------------------------
 132  I changed the names of some error messages:
 133  binary        -> binary_file
 134  cmd_unknown   -> command_unknown
 135  dir_read_fail -> dir_read_failed
 136  create_ar     -> create_above_root
 137  not_exist     -> not_found
 138
 139  File names containing a "+" sign:
 140  ---------------------------------
 141  If a file name contained a "+" sign, Dev-Editor was sometimes not able to
 142  access the file, because the "+" was interpreted as a space.
 143
 144  Check octal numbers:
 145  --------------------
 146  Before changing the permissions of a file, Dev-Editor now checks if the user
 147  entered a valid octal number.
 148
 149  Encoding of HTML entities:
 150  --------------------------
 151  - All HTML in output is now properly encoded
 152  - HTML::Entities is a little bit slow and does currently not support very much
 153    encodings. Now, we just encode the HTML control characters (<, >, & and ").
 154    This also means that Dev-Editor now does not require any CPAN module.
 155
 156  Template class updated:
 157  -----------------------
 158  The template class was updated to version 1.5.
 159
 160  Small changes:
 161  --------------
 162  - Don't show the "Copy" link if a file is not readable
 163  - Added checkboxes in the "Copy" and "Rename" dialogues for immediately
 164    overwriting an existing file
 165  - Preserve the directory listing filter if the user changes the directory using
 166    the input field at the bottom of the directory listing
 167
 168 New in version 2.3.2 (2005-04-23)
 169 ---------------------------------
 170
 171  Copying a file out of a directory:
 172  ----------------------------------
 173  Fixed a really strange bug occuring only on Windows systems.
 174  Dev-Editor was not able to copy (or move) a file out of a directory if the
 175  path, the user entered in the corresponding dialogue, was beginning with "../".
 176
 177  Empty root directory causes incomplete HTML table:
 178  --------------------------------------------------
 179  Dev-Editor now does not create an incomplete HTML table if the root directory
 180  is completely empty or no files are matching against the current wildcard.
 181
 182  move() instead of rename():
 183  ---------------------------
 184  Dev-Editor now uses the move() function from the File::Copy module to move or
 185  rename files and directories. move() is more reliable than the rename()
 186  function.
 187
 188  No error message if reading of a directory failed:
 189  --------------------------------------------------
 190  If reading of a directory failed, no error message was shown. I thought this
 191  bug was fixed...
 192
 193  Template class updated:
 194  -----------------------
 195  The template class was updated to version 1.4a.
 196
 197 New in version 2.3.1 (2005-02-19)
 198 ---------------------------------
 199
 200  Handling of symbolic links changed:
 201  -----------------------------------
 202  For security reasons, I completely changed the handling of symbolic links:
 203  Symbolic links are now treated as files, no matter where they point to. The
 204  user is just allowed to see the path where the link points to, he is allowed to
 205  delete the link, to rename it and to overwrite it by renaming an other file.
 206  Nothing else is allowed.
 207  Accessing a symbolic link pointing to a directory caused also a very strange
 208  effect: It was possible to access this directory, but you could not access
 209  the objects in it.
 210  I had to do it in this way because of the very stupid behaviour of abs_path()
 211  from the Cwd module: This function is just able to detect the absolute path of
 212  directories.
 213  Hard links are not affected by this, because it is not possible to detect them
 214  (at least I don't know how to detect them).
 215
 216  Root directory must not be a symbolic link:
 217  -------------------------------------------
 218  Now, the root directory must not be a symbolic link.
 219  Sorry for this, I really would have liked to allow the root directory to be a
 220  symbolic link, but if I would allow this, Dev-Editor would not be able to
 221  create files in the root directory. I'm looking for an alternative...
 222
 223  Use Greenwich Mean Time:
 224  ------------------------
 225  You may now use Greenwich Mean Time (GMT/UTC) in dates instead of the local
 226  time.
 227  I don't know if anyone needs this, but it could be useful.
 228
 229  Handle errors produced by File::UseList:
 230  ----------------------------------------
 231  - Check if unlocking of the list of files in use was successful
 232  - Check if a file could be successfully added to the list of files in use
 233  - Check if a file could be successfully removed from the list of files in use
 234
 235  Saving to non-existing files:
 236  -----------------------------
 237  The file saving process was aborted if the user wanted to write text data using
 238  the edit function into a file that does not exists.
 239  The reason was that Dev-Editor thought that this non-existing file was a binary
 240  file.
 241
 242  Template class updated:
 243  -----------------------
 244  The template class was updated to version 1.4.
 245  This fixes the problem of the infinitive loops produced by incorrectly nested
 246  {IF} blocks.
 247
 248  Small changes:
 249  --------------
 250  - Files locked with the flock() function are now unlocked by the close()
 251    function due to security reasons (see
 252    http://forum.de.selfhtml.org/?t=101375&m=622582)
 253  - Changed the names of two error messages:
 254    dircopy -> dir_copy
 255    editdir -> dir_edit
 256  - Fixed various small errors in some template files
 257  - The regular expression used by file_name() and upper_path() to detect Windows
 258    drive letters was not case-insensitive
 259
 260 New in version 2.3 (2005-01-08)
 261 -------------------------------
 262
 263  Filter directory listing:
 264  -------------------------
 265  Dev-Editor is now able to filter the directory listing using DOS-style
 266  wildcards.
 267  I think that is a little bit incomplete, Dev-Editor should be able to
 268  "remember" the filter wildcard during the actions.
 269  The code for parsing DOS-style wildcards is from the File::DosGlob module by
 270  Gurusamy Sarathy.
 271
 272  flock():
 273  --------
 274  Dev-Editor now uses flock().
 275  flock() is called using a wrapper function which checks if it is really
 276  available.
 277
 278  check_path() broken on Windows:
 279  -------------------------------
 280  On Windows systems the check_path() routine was heavily broken (this routine
 281  checks if someone tries to access a path above the virtual root directory). It
 282  was possible to access files above the root directory by accessing a path with
 283  "..." or "...." or something like that as the last path component. This bug was
 284  caused by the rewrite of check_path() in Dev-Editor 2.2.
 285
 286  "." or ".." as end of a path:
 287  -----------------------------
 288  If you enter a path with "." or ".." as the last path component, Dev-Editor
 289  showed a really strange behaviour by allowing to enter a path like
 290  "something/." or "something/..". This was also caused by the (poor) rewrite of
 291  check_path(). The problem is fixed now.
 292
 293  Paths beginning with "/../" caused problems:
 294  --------------------------------------------
 295  When composing the temporary virtual path for a new file, don't call
 296  clean_path(). It is unnecessary and it also caused a problem if this path would
 297  begin with /../, because on UNIX systems, canonpath() removes /../ at the
 298  beginning of a path. So if a user wanted to create the file /../file.ext (but
 299  he wasn't allowed to), he created /file.ext.
 300
 301  Deny changing file properties in some cases:
 302  --------------------------------------------
 303  - Do not allow to change the properties of the root directory
 304  - Do not allow to change the properties of a file in use
 305
 306  Deny overwriting files:
 307  -----------------------
 308  - While processing a file upload, check if the user wants to replace a
 309    directory or overwrite a write-protected file
 310  - If the user wants to copy or rename a file, check if he wants to overwrite a
 311    write-protected file
 312  - Do not allow to upload a file if a file with the same virtual name is
 313    currently in use
 314
 315  Validate file uploads:
 316  ----------------------
 317  Dev-Editor now tries to validate a file upload by checking the handle created
 318  by the CGI module.
 319
 320  Improved configuration file parser:
 321  -----------------------------------
 322  - The parser now ignores lines like that:
 323       = Value
 324    Such lines could lead to properties with empty keys in the configuration
 325    hash.
 326  - Allow configuration options with empty values
 327  - If a option is defined twice, the line number of the second one is shown in
 328    the error message
 329
 330  Output changes:
 331  ---------------
 332  - More encoding of HTML entities
 333  - In directory listing, the "Edit" link of files in use were not greyed (very
 334    nasty)
 335  - Show the name of the lock file in error messages even if it has not been
 336    defined in the configuration file
 337
 338  Small internal changes:
 339  -----------------------
 340  - The file saving process is now completely centralized in File::Access
 341  - When generating a redirection header, check if we really have to create a
 342    query string
 343  - Fixed a bug occuring if the "curdir" CGI parameter had no trailing slash and
 344    the "newfile" parameter had no leading slash
 345  - Dev-Editor now takes more care of Windows drive letters
 346  - Trying to increase speed of the script by surrounding static values by single
 347    quotes
 348  - Code cleaning
 349
 350 New in version 2.2a (2004-11-29)
 351 --------------------------------
 352
 353  File uploads did not work:
 354  --------------------------
 355  Dev-Editor normally tests if it has enough permissions to upload a file to a
 356  directory. But the condition was missing and so Dev-Editor always aborted file
 357  uploads and didn't even display the dialogue.
 358
 359 New in version 2.2 (2004-11-27)
 360 -------------------------------
 361
 362  `chgrp` system command and numerical group names:
 363  -------------------------------------------------
 364  When changing the group, Dev-Editor is now using the `chgrp` system command.
 365  This allows to use numerical group names. Before, Dev-Editor handled numerical
 366  values as group IDs.
 367
 368  Checking root directory:
 369  ------------------------
 370  Dev-Editor now checks if the root directory exists and if it may be accessed.
 371  This fixed also bug where it was possible to access the physical root directory
 372  if Dev-Editor could not enter the virtual root directory.
 373
 374  Checking directory permissions:
 375  -------------------------------
 376  Dev-Editor does some simple checks of directory permissions now:
 377  - Inaccessible directories are greyed in directory listing. You cannot access
 378    them, but the actions are not disabled, because they may work.
 379  - Actions needing write access to a directory are aborted if Dev-Editor has no
 380    write access.
 381
 382  Access a directory structure similar to the root directory:
 383  -----------------------------------------------------------
 384  The path the user wants to access must now BEGIN with the root directory. The
 385  old check made it possible to access a directory structure outside the root
 386  directory similar to the root directory.
 387
 388  Changing mode of a directory with mode 000:
 389  -------------------------------------------
 390  It was not possible to change the mode of a directory with mode 000.
 391
 392  Upload only to directories:
 393  ---------------------------
 394  Dev-Editor now checks if the user really uploads a file to a directory.
 395
 396  Improved About dialogue:
 397  ------------------------
 398  - Dev-Editor now only shows the main group ID of the process user.
 399  - Dev-Editor also shows the current umask of the process.
 400  - Special chars in most values are now encoded to entities.
 401
 402  Added <label> tags:
 403  -------------------
 404  For a better usability in some browsers, I added <label> tags for the
 405  checkboxes and radio buttons in file edit and file upload dialogue.
 406
 407  Directory links in error messages:
 408  ----------------------------------
 409  Some error messages generated by the main program now contain a link to the
 410  root directory.
 411
 412  Bugs in HTML generation:
 413  ------------------------
 414  - If Dev-Editor could not read a directory, it did neither display an error
 415    message nor a directory link.
 416  - Some error messages had problems with {DIR} variables. Thus the variable in
 417    error.htm which will be replaced by a back link is now called "{BACK}".
 418  - When viewing a file, Dev-Editor inserts the contents of the file into the
 419    viewfile.htm template file AFTER parsing the "editable" {IF}-block, because
 420    Dev-Editor showed a very ugly behaviour when viewing this template file.
 421
 422  Code cleaning:
 423  --------------
 424  I tried to clean the source code of Dev-Editor a little bit. Some parts of the
 425  code were optimized.
 426
 427 New in version 2.1a (2004-10-22)
 428 --------------------------------
 429
 430  Changed file saving error handling:
 431  -----------------------------------
 432  Now we already unlock the file saving process, because if an error occurs
 433  during this process, the file keeps locked.
 434  This is not a perfect solution, there are still problems. I have to figure out
 435  another one.
 436
 437 New in version 2.1 (2004-10-14)
 438 -------------------------------
 439
 440  Overwrite files during file upload:
 441  -----------------------------------
 442  In file upload dialogue, there is a new checkbox which allows to overwrite
 443  files during file upload if they already exist.
 444
 445  Improved file saving:
 446  ---------------------
 447  The process of file saving has been improved:
 448  - Saving even works if the file has to be created first.
 449  - Dev-Editor is now checking if the user wants to write text data into a binary
 450    file.
 451  - If the user just entered spaces as filename (detection works for other
 452    commands using the "newfile" CGI parameter too), we use the original
 453    filename.
 454
 455  Don't copy a directory:
 456  -----------------------
 457  Dev-Editor now denies copying a directory.
 458
 459  Check before manually unlocking:
 460  --------------------------------
 461  Dev-Editor now checks if the file is really locked before displaying the
 462  dialogue for manually unlocking a file. If it is not locked, Dev-Editor returns
 463  to directory view. Dev-Editor also behaves in this way if it is trying to
 464  unlock a file.
 465
 466  Wrong error messages:
 467  ---------------------
 468  Something definitely went wrong when I remade the copy and the rename
 469  functions: They printed a wrong error message if the destination already
 470  existed and if it was a file.
 471
 472 New in version 2.0 (2004-08-10)
 473 -------------------------------
 474
 475  File uploads:
 476  -------------
 477  Dev-Editor is now able to process HTTP file uploads. The files may be
 478  transferred in ASCII or binary mode (similar to FTP).
 479
 480  Change mode and group:
 481  ----------------------
 482  Dev-Editor is now able to change the mode and the group of a file or a
 483  directory.
 484
 485  HTTPS support and non-default ports:
 486  ------------------------------------
 487  Dev-Editor is now able to detect a HTTPS connection and if the web server
 488  doesn't listen on the default ports (necessary for reloading Dev-Editor).
 489
 490  Do not allow removing or renaming the root directory:
 491  -----------------------------------------------------
 492  Dev-Editor now denies removing or renaming the root directory.
 493
 494  Renaming files outside the root directory:
 495  ------------------------------------------
 496  There was a bug which caused Dev-Editor not to rename files outside the root
 497  directory if they already exist.
 498
 499  Improved file editing:
 500  ----------------------
 501  When the user wants to save an edited file using a different file name,
 502  Dev-Editor now unlocks the original file and checks if a file with this
 503  different name already exists and if it is locked.
 504
 505  Improved file creating:
 506  -----------------------
 507  The routine which creates empty files had a race condition which could set
 508  files to 0 if they already exist.
 509
 510  Maximum size for files:
 511  -----------------------
 512  The administrator may now define a maximum size for files in the main
 513  configuration file. If the user wants to view or edit a file larger than this
 514  defined size, Dev-Editor denies file access (but the file can still be copied,
 515  renamed or removed).
 516
 517  Form for creating new files or directories:
 518  -------------------------------------------
 519  In directory listing, when clicking on the buttons next to the fields for
 520  creating new files and directories without entering a file or directory name,
 521  the user got an error message which is a little bit strange.
 522  Now, the user will see a form for creating new files or directories.
 523
 524  Newlines are converted while reading:
 525  -------------------------------------
 526  Whenever Dev-Editor now reads a file for output, it converts any line separator
 527  to the system specific one.
 528
 529  Case-insensitive commands:
 530  --------------------------
 531  The commands are now case-insensitive, so the command "ShOw" is the same as
 532  "show".
 533
 534  About screen:
 535  -------------
 536  There is now a small "About" screen which shows some more or less useful
 537  information about Dev-Editor and the system.
 538
 539  Improvements for user interface:
 540  --------------------------------
 541  Made a lot of improvements for the user interface:
 542  - The directory listing is now built using tables.
 543  - When editing a file and the user wants to save a file using a different file
 544    name, the checkbox for saving the file using a different file name is
 545    activated using JavaScript.
 546  - In directory listing or when viewing a file, there is a new field for quickly
 547    jumping to a file or to a directory.
 548  - Separated "Work with directory" and "Work with file" into different options
 549    in directory listing ("Copy", "Rename", "Delete", "Unlock"). The options also
 550    have their own dialogues.
 551  - In directory listing, there is a new link for viewing a file or a directory
 552    in the browser.
 553  - When viewing a file and if the file is editable, there is a new link to edit
 554    this  file.
 555  - Files and directories in directory listing are now sorted case-insensitively.
 556
 557  Configuration files:
 558  --------------------
 559  The settings of Dev-Editor are now stored in extern configuration files: There
 560  is one file for general settings, one for the error messages and one for the
 561  paths to the template files.
 562
 563  Templates:
 564  ----------
 565  The output of Dev-Editor is now controlled by template files. The source code
 566  became much cleaner :-)
 567
 568 New in version 1.2 (2003-12-29)
 569 -------------------------------
 570
 571  Removing directories:
 572  ---------------------
 573  Dev-Editor is now able to completely remove a directory.
 574
 575  "Work with directories":
 576  ------------------------
 577  In directory listing, next do a directory, there is a new link called "Work
 578  with directory". When you select this link, you get a form to remove or
 579  rename/move the directory.
 580  Additionally, the link "Do other stuff" was renamed to "Work with file".
 581
 582  Overwriting existing files:
 583  ---------------------------
 584  If you want to copy a file, and the destination file already exists, you will
 585  be asked to overwrite the file. If the destination points to a directory,
 586  copying will be aborted completely.
 587  If you want to rename a file or a directory, and the destination file already
 588  exists, you will be asked to overwrite the file. If the destination points to a
 589  directory, renaming will be aborted completely.
 590
 591  Confirmation for removing files:
 592  --------------------------------
 593  If you want to remove a file, a confirmation dialog will be displayed first.
 594
 595  Fixed open() calls:
 596  -------------------
 597  It seems that some systems don't support the FILEHANDLE,MODE,FILENAME version
 598  of open(). Now we don't use it any more.
 599
 600  Default permissions for mkdir():
 601  --------------------------------
 602  Set the permissions for mkdir() to 0777. I thought it is optional (as described
 603  in "perlfunc"), but some systems need it.
 604
 605 New in version 1.1 (2003-11-15)
 606 -------------------------------
 607
 608  Newlines are converted:
 609  -----------------------
 610  Any line seperator will now be converted to the system specific line seperator
 611  if you save a text file.
 612
 613  File permissions are checked:
 614  -----------------------------
 615  Dev-Editor now runs some simple checks on the file permissions when it creates
 616  a directory listing, tries to view or edit a file and when it copies a file.
 617
 618  Tool tips for file status:
 619  --------------------------
 620  In directory listing, when a file cannot be viewed or edited, a tool tip on the
 621  "View" or "Edit" link will show the reason why it is so.
 622
 623  File permissions are saved:
 624  ---------------------------
 625  When the user saves a text file, the file permissions were destroyed. The
 626  reason was that a temporary file was used, which was renamed to the originally
 627  file. Now this is fixed, but if saving of the file now fails, the file could be
 628  damaged...
 629
 630  Links in error messages:
 631  ------------------------
 632  Some error messages now contain a link to go back to the directory containing
 633  the file which caused the error.
 634
 635  Typos fixed:
 636  ------------
 637  There were a lot of typos in the output, the comments and the ReadMe file.
 638
 639  Dates fixed:
 640  ------------
 641  The dates of the last modification in the head comment of the files had the
 642  wrong format. They had the format MM-DD-YYYY, but they should have YYYY-MM-DD.
 643  Sorry, that was VERY embarassing...
 644
 645 New in version 1.0 (2003-10-08)
 646 -------------------------------
 647
 648  First public release:
 649  ---------------------
 650  This is the first public release of Dev-Editor.
 651
 652 ------------------------------------------------
