330 | * closest to the target. If the allocation of this close color fails, | |
331 | * which almost never happens, then one of two scenarios is possible. | |
332 | * Either the colormap must have changed (since the last close color | |
333 | * allocation or possibly while we were sorting the colormap), or the | |
334 | * color is allocated as Read/Write by some other client. (Note: X | |
335 | * _should_ allow clients to check if a particular color is Read/Write, | |
336 | * but it doesn't! :-( ). We cannot determine which of these scenarios | |
337 | * occurred, so we try the next closest color, and so on, until no more | |
338 | * colors are within closeness of the target. If we knew that the | |
339 | * colormap had changed, we could skip this sequence. | |
340 | * | |
341 | * If _none_ of the colors within closeness of the target can be allocated, | |
342 | * then we can finally be pretty sure that the colormap has actually | |
343 | * changed. In this case we try to allocate the original color (again), | |
344 | * then try the closecolor stuff (again)... | |
345 | * | |
346 | * In theory it would be possible for an infinite loop to occur if another | |
347 | * process kept changing the colormap every time we sorted it, so we set | |
348 | * a maximum on the number of iterations. After this many tries, we use | |
349 | * XGrabServer() to ensure that the colormap remains unchanged. | |
350 | * | |
351 | * This approach gives particularly bad worst case performance - as many as | |
352 | * <MaximumIterations> colormap reads and sorts may be needed, and as | |
353 | * many as <MaximumIterations> * <ColormapSize> attempted allocations | |
354 | * may fail. On an 8-bit system, this means as many as 3 colormap reads, | |
355 | * 3 sorts and 768 failed allocations per execution of this code! | |
356 | * Luckily, my experiments show that in general use in a typical 8-bit | |
357 | * color environment only about 1 in every 10000 allocations fails to | |
358 | * succeed in the fastest possible time. So virtually every time what | |
359 | * actually happens is a single sort followed by a successful allocate. | |
360 | * The very first allocation also costs a colormap read, but no further | |
361 | * reads are usually necessary. | |
