327 | * Either the colormap must have changed (since the last close color | |
328 | * allocation or possibly while we were sorting the colormap), or the | |
329 | * color is allocated as Read/Write by some other client. (Note: X | |
330 | * _should_ allow clients to check if a particular color is Read/Write, | |
331 | * but it doesn't! :-( ). We cannot determine which of these scenarios | |
332 | * occurred, so we try the next closest color, and so on, until no more | |
333 | * colors are within closeness of the target. If we knew that the | |
334 | * colormap had changed, we could skip this sequence. | |
ea258ad3 | 335 | * |
cfbe03c9 JS |
336 | * If _none_ of the colors within closeness of the target can be allocated, |
337 | * then we can finally be pretty sure that the colormap has actually | |
338 | * changed. In this case we try to allocate the original color (again), | |
339 | * then try the closecolor stuff (again)... | |
ea258ad3 | 340 | * |
cfbe03c9 JS |
341 | * In theory it would be possible for an infinite loop to occur if another |
342 | * process kept changing the colormap every time we sorted it, so we set | |
343 | * a maximum on the number of iterations. After this many tries, we use | |
344 | * XGrabServer() to ensure that the colormap remains unchanged. | |
ea258ad3 | 345 | * |
cfbe03c9 JS |
346 | * This approach gives particularly bad worst case performance - as many as |
347 | * <MaximumIterations> colormap reads and sorts may be needed, and as | |
348 | * many as <MaximumIterations> * <ColormapSize> attempted allocations | |
349 | * may fail. On an 8-bit system, this means as many as 3 colormap reads, | |
350 | * 3 sorts and 768 failed allocations per execution of this code! | |
351 | * Luckily, my experiments show that in general use in a typical 8-bit | |
352 | * color environment only about 1 in every 10000 allocations fails to | |
353 | * succeed in the fastest possible time. So virtually every time what | |
354 | * actually happens is a single sort followed by a successful allocate. | |
355 | * The very first allocation also costs a colormap read, but no further | |
356 | * reads are usually necessary. | |
