gnuclient: if TMPDIR was set and connect failed, try again with /tmp
2011-06-03 Aidan Kehoe <kehoea@parhasard.net>
* gnuslib.c (connect_to_unix_server):
Retry with /tmp as a directory in which to search for Unix sockets
if an attempt to connect with some other directory failed (which
may be because gnuclient and gnuserv don't share an environment
value for TMPDIR, or because gnuserv was compiled with USE_TMPDIR
turned off).

| 32 | |
| 442 | 33 ;; Dialog boxes are non-modal at the C level, but made modal at the |
| 34 ;; Lisp level via hacks in functions such as yes-or-no-p-dialog-box | |
| 35 ;; below. Perhaps there should be truly modal dialog boxes | |
| 36 ;; implemented at the C level for safety. All code using dialog boxes | |
| 37 ;; should be careful to assume that the environment, for example the | |
| 38 ;; current buffer, might be completely different after returning from | |
| 39 ;; yes-or-no-p-dialog-box, but such code is difficult to write and test. | |

124 spec &allow-other-keys) |
| 442 | 125 "Pop up a dialog box. |
| 126 TYPE is a symbol, the type of dialog box. Remaining arguments are | |
| 127 keyword-value pairs, specifying the particular characteristics of the | |
| 128 dialog box. The allowed keywords are particular to each type, but | |
| 129 some standard keywords are common to many types: | |
| 130 | |
| 131 :title | |
| 132 The title of the dialog box's window. | |
| 133 | |
| 134 :modal | |
| 135 If true, indicates that XEmacs will wait until the user is \"done\" | |
| 136 with the dialog box (usually, this means that a response has been | |
| 137 given). Typically, the response is returned. NOTE: Some dialog | |
| 138 boxes are always modal. If the dialog box is modal, `make-dialog-box' | |
| 139 returns immediately. The return value will be either nil or a | |
| 140 dialog box handle of some sort, e.g. a frame for type `general'. | |
| 141 | |
| 142 --------------------------------------------------------------------------- | |
| 143 | |
| 144 Recognized types are | |
| 145 | |
| 146 general | |
| 147 A dialog box consisting of an XEmacs glyph, typically a `layout' | |
| 148 widget specifying a dialog box arrangement. This is the most | |
| 149 general and powerful dialog box type, but requires more work than | |
| 150 the other types below. | |
| 151 | |
| 152 question | |
| 153 A simple dialog box that displays a question and contains one or | |
| 154 more user-defined buttons to specify possible responses. (This is | |
| 155 compatible with the old built-in dialog boxes formerly specified | |
| 156 using `popup-dialog-box'.) | |
| 157 | |
| 158 file | |
| 159 A file dialog box, of the type typically used in the window system | |
| 160 XEmacs is running on. | |
| 161 | |
| 162 color | |
| 163 A color picker. | |
| 164 | |
| 165 find | |
| 166 A find dialog box. | |
| 167 | |
| 168 font | |
| 169 A font chooser. | |
| 170 | |
| 171 print | |
| 172 A dialog box used when printing (e.g. number of pages, printer). | |
| 173 | |
| 174 page-setup | |
| 175 A dialog box for setting page options (e.g. margins) for printing. | |
| 176 | |
| 177 replace | |
| 178 A find/replace dialog box. | |
| 179 | |
| 180 mswindows-message | |
| 181 An MS Windows-specific standard dialog box type similar to `question'. | |
| 182 | |
| 183 --------------------------------------------------------------------------- | |
| 184 | |
| 185 For type `general': | |
| 186 | |
| 187 This type creates a frame and puts the specified widget layout in it. | |
| 188 \(Currently this is done by eliminating all areas but the gutter and placing | |
| 189 the layout there; but this is an implementation detail and may change.) | |
| 190 | |
| 191 The keywords allowed for `general' are | |
| 192 | |
| 193 :spec | |
| 194 The widget spec -- anything that can be passed to `make-glyph'. | |
| 195 :title | |
| 196 The title of the frame. | |
| 197 :parent | |
| 198 The frame is made a child of this frame (defaults to the selected frame). | |
| 199 :properties | |
| 200 Additional properties of the frame, as well as `dialog-frame-plist'. | |
| 863 | 201 :autosize |
| 202 If t the frame is sized to exactly fit the widgets given by :spec. | |
| 442 | 203 |
| 204 --------------------------------------------------------------------------- | |
| 205 | |
| 206 For type `question': | |
| 207 | |
| 208 The keywords allowed are | |
| 209 | |
| 210 :modal | |
| 211 t or nil. When t, the dialog box callback should exit the dialog box | |
| 212 using the functions `dialog-box-finish' or `dialog-box-cancel'. | |
| 213 :title | |
| 214 The title of the frame. | |
| 215 :question | |
| 216 A string, the question. | |
| 217 :buttons | |
| 218 A list, describing the buttons below the question. Each of these is a | |
| 219 vector, the syntax of which is essentially the same as that of popup menu | |
| 220 items. They may have any of the following forms: | |
| 221 | |
| 222 [ \"name\" callback <active-p> ] | |
| 223 [ \"name\" callback <active-p> \"suffix\" ] | |
| 224 [ \"name\" callback :<keyword> <value> :<keyword> <value> ... ] | |
| 225 | |
| 226 The name is the string to display on the button; it is filtered through the | |
| 227 resource database, so it is possible for resources to override what string | |
| 228 is actually displayed. | |
| 229 | |
| 230 Accelerators can be indicated in the string by putting the sequence | |
| 231 \"%_\" before the character corresponding to the key that will invoke | |
| 232 the button. Uppercase and lowercase accelerators are equivalent. The | |
| 233 sequence \"%%\" is also special, and is translated into a single %. | |
| 234 | |
| 235 If the `callback' of a button is a symbol, then it must name a command. | |
| 236 It will be invoked with `call-interactively'. If it is a list, then it is | |
| 237 evaluated with `eval'. | |
| 238 | |
| 239 One (and only one) of the buttons may be `nil'. This marker means that all | |
| 240 following buttons should be flushright instead of flushleft. | |
| 241 | |
| 242 Though the keyword/value syntax is supported for dialog boxes just as in | |
| 243 popup menus, the only keyword which is both meaningful and fully implemented | |
| 244 for dialog box buttons is `:active'. | |
| 245 | |
| 246 --------------------------------------------------------------------------- | |
| 247 | |
| 248 For type `file': | |
| 249 | |
| 250 The keywords allowed are | |
| 251 | |
| 252 :initial-filename | |
| 253 The initial filename to be placed in the dialog box (defaults to nothing). | |
| 254 :initial-directory | |
| 255 The initial directory to be selected in the dialog box (defaults to the | |
| 256 current buffer's `default-directory). | |
| 257 :filter-list | |
| 258 A list of (filter-desc filter ...) | |
| 259 :title | |
| 260 The title of the dialog box (defaults to \"Open\"). | |
| 261 :allow-multi-select t or nil | |
| 262 :create-prompt-on-nonexistent t or nil | |
| 263 :overwrite-prompt t or nil | |
| 264 :file-must-exist t or nil | |
| 265 :no-network-button t or nil | |
| 266 :no-read-only-return t or nil | |
| 267 | |
| 268 --------------------------------------------------------------------------- | |
| 269 | |
| 673 | 270 For type `directory': |
| 271 | |
| 272 The keywords allowed are | |
| 273 | |
| 274 :initial-directory | |
| 275 The initial directory to be selected in the dialog box (defaults to the | |
| 276 current buffer's `default-directory). | |
| 277 :title | |
| 278 The title of the dialog box (defaults to \"Open\"). | |
| 279 | |
| 280 --------------------------------------------------------------------------- | |
| 281 | |
| 442 | 282 For type `print': |
| 283 | |
| 284 This invokes the Windows standard Print dialog. | |
| 285 This dialog is usually invoked when the user selects the Print command. | |
| 286 After the user presses OK, the program should start actual printout. | |
| 287 | |
| 288 The keywords allowed are | |
| 289 | |
| 290 :device | |
| 291 An 'msprinter device. | |
| 292 :print-settings | |
| 293 A printer settings object. | |
| 510 | 294 :allow-selection |
| 295 t or nil -- whether the \"Selection\" button is enabled (defaults to nil). | |
| 296 :allow-pages | |
| 297 t or nil -- whether the \"Pages\" button and associated edit controls | |
| 298 are enabled (defaults to t). | |
| 299 :selected-page-button | |
| 300 `all', `selection', or `pages' -- which page button is initially | |
| 301 selected. | |
| 442 | 302 |
| 510 | 303 Exactly one of :device and :print-settings must be given. |
| 442 | 304 |
| 305 The function brings up the Print dialog, where the user can | |
| 506 | 306 select a different printer and/or change printer options. Connection |
| 442 | 307 name can change as a result of selecting a different printer device. If |
| 506 | 308 a device is specified, then changes are stored into the settings object |
| 442 | 309 currently selected into that printer. If a settings object is supplied, |
| 629 | 310 then changes are recorded into it, and, it is selected into a |
| 442 | 311 printer, then changes are propagated to that printer |
| 312 too. | |
| 313 | |
| 314 Return value is nil if the user has canceled the dialog. Otherwise, it | |
| 315 is a new plist, with the following properties: | |
| 510 | 316 name Printer device name, even if unchanged by the user. |
| 317 from-page First page to print, 1-based. Returned if | |
| 318 `selected-page-button' is `pages'. | |
| 319 user, then this value is not included in the plist. | |
| 320 to-page Last page to print, inclusive, 1-based. Returned if | |
| 321 `selected-page-button' is `pages'. | |
| 322 copies Number of copies to print. Always returned. | |
| 323 selected-page-button Which page button was selected (`all', `selection', | |
| 324 or `pages'). | |
| 442 | 325 |
| 326 The DEVICE is destroyed and an error is signaled in case of | |
| 327 initialization problem with the new printer. | |
| 328 | |
| 510 | 329 See also the `page-setup' dialog box type. |
| 442 | 330 |
| 331 --------------------------------------------------------------------------- | |
| 332 | |
| 333 For type `page-setup': | |
| 334 | |
| 335 This invokes the Windows standard Page Setup dialog. | |
| 506 | 336 This dialog is usually invoked in response to the Page Setup command, |
| 337 and used to choose such parameters as page orientation, print margins | |
| 338 etc. Note that this dialog contains the \"Printer\" button, which | |
| 339 invokes the Printer Setup dialog so that the user can update the | |
| 340 printer options or even select a different printer as well. | |
| 442 | 341 |
| 342 The keywords allowed are | |
| 343 | |
| 344 :device | |
| 345 An 'msprinter device. | |
| 346 :print-settings | |
| 347 A printer settings object. | |
| 348 :properties | |
| 349 A plist of job properties. | |
| 350 | |
| 351 Exactly one of these keywords must be given. | |
| 352 | |
| 353 The function brings up the Page Setup dialog, where the user | |
| 354 can select a different printer and/or change printer options. | |
| 355 Connection name can change as a result of selecting a different printer | |
| 506 | 356 device. If a device is specified, then changes are stored into the |
| 442 | 357 settings object currently selected into that printer. If a settings |
| 629 | 358 object is supplied, then changes are recorded into it, and, it is |
| 442 | 359 selected into a printer, then changes are propagated to that printer |
| 360 too. | |
| 361 | |
| 362 :properties specifies a plist of job properties; | |
| 363 see `default-msprinter-frame-plist' for the complete list. The plist | |
| 364 is used to initialize the dialog. | |
| 365 | |
| 366 Return value is nil if the user has canceled the dialog. Otherwise, | |
| 367 it is a new plist, containing the new list of properties. | |
| 368 | |
| 506 | 369 NOTE: The margin properties (returned by this function) are *NOT* stored |
| 370 into the print-settings or device object. | |
| 371 | |
| 442 | 372 The DEVICE is destroyed and an error is signaled in case of |
| 373 initialization problem with the new printer. | |
| 374 | |
| 510 | 375 See also the `print' dialog box type. |
| 442 | 376 |
| 377 --------------------------------------------------------------------------- | |
| 378 | |
| 379 For type `mswindows-message': | |
| 380 | |
| 381 The keywords allowed are | |
| 382 | |
| 383 :title | |
| 384 The title of the dialog box. | |
| 385 :message | |
| 386 The string to display. | |
| 387 :flags | |
| 388 A symbol or list of symbols: | |
| 389 | |
| 390 -- To specify the buttons in the message box: | |
| 391 | |
| 392 abortretryignore | |
| 393 The message box contains three push buttons: Abort, Retry, and Ignore. | |
| 394 ok | |
| 395 The message box contains one push button: OK. This is the default. | |
| 396 okcancel | |
| 397 The message box contains two push buttons: OK and Cancel. | |
| 398 retrycancel | |
| 399 The message box contains two push buttons: Retry and Cancel. | |

| 431 -- To indicate the modality of the dialog box: | |
| 432 | |
| 433 applmodal | |
| 434 The user must respond to the message box before continuing work in | |
| 435 the window identified by the hWnd parameter. However, the user can | |
| 436 move to the windows of other applications and work in those windows. | |
| 437 Depending on the hierarchy of windows in the application, the user | |
| 438 may be able to move to other windows within the application. All | |
| 439 child windows of the parent of the message box are automatically | |
| 440 disabled, but popup windows are not. This is the default. | |
| 441 systemmodal | |
| 442 Same as applmodal except that the message box has the WS_EX_TOPMOST | |
| 443 style. Use system-modal message boxes to notify the user of serious, | |
| 444 potentially damaging errors that require immediate attention (for | |
| 445 example, running out of memory). This flag has no effect on the | |
| 446 user's ability to interact with windows other than those associated | |
| 447 with hWnd. | |
| 448 taskmodal | |
| 449 Same as applmodal except that all the top-level windows belonging to | |
| 450 the current task are disabled if the hWnd parameter is NULL. Use | |
| 451 this flag when the calling application or library does not have a | |
| 452 window handle available but still needs to prevent input to other | |
| 453 windows in the current application without suspending other | |
| 454 applications. | |
| 455 | |
| 456 | |
| 457 In addition, you can specify the following flags: | |
| 458 | |
| 459 default-desktop-only | |
| 460 The desktop currently receiving input must be a default desktop; | |
| 461 otherwise, the function fails. A default desktop is one an | |
| 462 application runs on after the user has logged on. | |
| 463 help | |
| 464 Adds a Help button to the message box. Choosing the Help button or | |
| 465 pressing F1 generates a Help event. | |
| 466 right | |
| 467 The text is right-justified. | |
| 468 rtlreading | |
| 469 Displays message and caption text using right-to-left reading order | |
| 470 on Hebrew and Arabic systems. | |
| 471 setforeground | |
| 472 The message box becomes the foreground window. Internally, Windows | |
| 473 calls the SetForegroundWindow function for the message box. | |
| 474 topmost | |
| 475 The message box is created with the WS_EX_TOPMOST window style. | |
| 476 service-notification | |
| 477 Windows NT only: The caller is a service notifying the user of an | |
| 478 event. The function displays a message box on the current active | |
| 479 desktop, even if there is no user logged on to the computer. If | |
| 480 this flag is set, the hWnd parameter must be NULL. This is so the | |
| 481 message box can appear on a desktop other than the desktop | |
| 482 corresponding to the hWnd. | |
| 483 | |
| 484 | |
| 485 The return value is one of the following menu-item values returned by | |
| 486 the dialog box: | |
| 487 | |
| 488 abort | |
| 489 Abort button was selected. | |
| 490 cancel | |
| 491 Cancel button was selected. | |
| 492 ignore | |
| 493 Ignore button was selected. | |
| 494 no | |
| 495 No button was selected. | |
| 496 ok | |
| 497 OK button was selected. | |
| 498 retry | |
| 499 Retry button was selected. | |
| 500 yes | |
| 501 Yes button was selected. | |
| 502 | |
| 503 If a message box has a Cancel button, the function returns the | |
| 504 `cancel' value if either the ESC key is pressed or the Cancel button | |
| 505 is selected. If the message box has no Cancel button, pressing ESC has | |
| 506 no effect." | |

| 510 ;; ok, this is extremely tricky. normally a modal | |
| 511 ;; dialog will pop itself down using (dialog-box-finish) | |
| 512 ;; or (dialog-box-cancel), which throws back to this | |
| 513 ;; catch. but question dialog boxes pop down themselves | |
| 514 ;; regardless, so a badly written question dialog box | |
| 515 ;; that does not use (dialog-box-finish) could seriously | |
| 516 ;; wedge us. furthermore, we disable all other frames | |
| 517 ;; in order to implement modality; we need to restore | |
| 518 ;; them before the dialog box is destroyed, because | |
| 519 ;; otherwise windows at least will notice that no top- | |
| 520 ;; level window can have the focus and will shift the | |
| 521 ;; focus to a different app, raising it and obscuring us. | |
| 522 ;; so we create `delete-dialog-box-hook', which is | |
| 523 ;; called right *before* the dialog box gets destroyed. | |
| 524 ;; here, we put a hook on it, and when it's our dialog | |
| 525 ;; box and not someone else's that's being destroyed, | |
| 526 ;; we reenable all the frames and remove the hook. | |
| 527 ;; BUT ... we still have to deal with exiting the | |
| 528 ;; modal loop in case it doesn't happen before us. | |
| 529 ;; we can't do this until after the callbacks for this | |
| 530 ;; dialog box get executed, and that doesn't happen until | |
| 531 ;; after the dialog box is destroyed. so to keep things | |
| 532 ;; synchronous, we enqueue an eval event, which goes into | |
| 533 ;; the same queue as the misc-user events encapsulating | |
| 534 ;; the dialog callbacks and will go after it (because | |
| 535 ;; destroying the dialog box happens after processing | |
| 536 ;; its selection). if the dialog boxes are written | |
| 537 ;; properly, we don't see this eval event, because we've | |
| 538 ;; already exited our modal loop. (Thus, we make sure the | |
| 539 ;; function given in this eval event is actually defined | |
| 540 ;; and does nothing.) If we do see it, though, we know | |
| 541 ;; that we encountered a badly written dialog box and | |
| 542 ;; need to exit now. Currently we just return nil, but | |
