165 J\'ai fini par utiliser la fonction suivante:
166 [code=php]
167 function png_has_transparency($im) {
168 //Retrieve content from imagick object
169 $content = $im->getImageBlob();
170
171 //Detect 32bit png (each pixel has tranparency level)

178 //Loop on each row pixel

188 return true;
189 }
190
191 //Didn\'t found clue of transparency
192 return false;
193 }
194 [/code]
195
196 Cette fonction fonctionne avec les deux seules possibilitées : PNG 32bit et 8bit.
197
198 Le premier cas est un PNG 32bit avec transparence activé, on doit alors vérifier l\'opacité de chaque pixel savoir si l\'image a de la transparence ou non.
199
200 Le second cas est un PNG 8 bit, on a simplement à détecter un marqueur de transparence dans le contenu du fichier.
201
202 Dans cette configuration de fonction, on lit seulement une partie du PNG 32bit jusqu\'à détection d\'un pixel transparent ou on analyse le contenu jusqu\'à trouver un marqueur de transparence dans un PNG 8bit.
203
204 Les pires cas seront un PNG 32bit avec marqueur de transparence sans pixel transparent ou PNG 8bit sans marqueur de transparence.
205
206 Selon les probabilités de rencontrer les différents cas de transparence vous pouvez être intéressé pour renverser l\'ordre des tests de cette fonction.

225 I finished using the following function:
226 [code=php]
227 function png_has_transparency($im) {
228 //Retrieve content from imagick object
229 $content = $im->getImageBlob();
230
231 //Detect 32bit png (each pixel has tranparency level)
232 if (ord(substr($content, 25, 1)) & 4) {
233 //Fetch iterator
234 $p = $im->getPixelIterator();

236 //Loop on each row

238 //Loop on each row pixel

248 return true;
249 }
250
251 //Didn\'t found clue of transparency
252 return false;
253 }
254 [/code]
255
256 This function works with the only two transparency possibilities: 32bit and 8bit PNG.
257
258 The first case is a 32bit PNG with transparency enabled, we have then to check every pixel to detect if it has transparent part or not.
259
260 The second case is a 8bit PNG, then we only have to look the file content for transparency markers.
261
262 In this function configuration, we only read part of the file in 32bit PNG until we detect one transparent pixel or parse content until transparency marker is detected in 8bit PNG.
263
264 The worst case scenario will be 32bit PNG with transparency flag without transparency or 8bit PNG without transparency flag.
265
266 Depending on how likely you are to have transparency in each cases you might want to reverse the flow of this function.
267

281 'description' => 'J\'ai eu récemment à trouver comment mettre en cache les réponse d\'un webservice.
282 Voici la configuration varnish qui a répondu à mes besoins.',
283 'body' => 'J\'ai eu récemment à trouver comment mettre en cache les réponse d\'un webservice.
284
285 L\'API RESTfull du webservice sert de passerelle entre un API privé HATEOAS et un client générant plus de 500 000 requêtes par jour.
286
287 La première surprise est qu\'un client bien élevé, envoyant un en-tête Authorization: Bearer <token>, ne sera pas mis en cache par Varnish par défaut !
288
289 Forçons le fonctionnement standard avec l\'en-tête pour le préfixe de l\'uri de notre webservice:
290 [code=varnish]
291 sub vcl_recv {
292 # Force la mise en cache de la réponse même avec req.http.Authorization présent
293 if (req.http.Authorization) {
294 if (req.url ~ "^/webservice/uri/prefix/") {
295 return (lookup);
296 }
297 }
298 }
299 [/code]
300
301 Ce changement a des conséquences sur la sécurité, n\'importe qui autorisé à interroger Varnish sera en mesure de récupérer un résultat en cache sans s\'identifier.
302
303 Il peut être une bonne idée de valider la valeur de l\'en-tête Authorization avant de fournir le résultat en cache.
304
305 Notre webservice a trois réponses possibles :
306 [ul]
307 [li]200: les données en JSON[/li]
308 [li]404: données non trouvées[/li]
309 [li]410: données plus jamais disponibles[/li]
310 [/ul]
311
312 Mettons en cache les résultats selon le code de retour :
313 [code=varnish]
314 sub vcl_fetch {
315 if (req.url ~ "^/webservice/uri/prefix/") {
316 if (beresp.status == 404) {
317 set beresp.ttl = 7d;
318 }
319 if (beresp.status == 410) {
320 set beresp.ttl = 7d;
321 }
322 if (beresp.status == 200) {
323 set beresp.ttl = 24h;
324 }
325 }
326 }
327 [/code]
328
329 Avec cette configuration, on a divisé par 5 la quantité de demandes sur notre passerelle
330 pour le client qui n\'était pas en mesure de mettre en cache lui-même nos résultats.'
331 ),
332 'en' => array(
333 'title' => 'Caching webservice with varnish',

335 Here is the Varnish configuration fitting my needs.',
336 'body' => 'I recently had to find a way to cache a webservice anwsers.
337
338 The webservice is a RESTfull API serving as a gateway between a private HATEOAS API and a client generating more than 500 000 requests a day.
339
340 The first surprise is that if your well educated client, sending you a header Authorization: Bearer <token>, will not be cached by default by Varnish !
341
342 Let\'s force back the standard behaviour with this header for our webservice uri prefix:
343 [code=varnish]
344 sub vcl_recv {
345 # Force cache response even with req.http.Authorization set
346 if (req.http.Authorization) {
347 if (req.url ~ "^/webservice/uri/prefix/") {
348 return (lookup);
349 }
350 }
351 }
352 [/code]
353
354 This has security implication, now anyone allowed to request varnish will be able to retrieve a cached result without authentification.
355
356 It may be a good idea to validate the Authorization header value before serving the cached result.
357
358 Now, our webservice has three possibles answers :
359 [ul]
360 [li]200: the data in JSON[/li]
361 [li]404: data was not found[/li]
362 [li]410: data is not available anymore[/li]
363 [/ul]
364
365 Let\'s cache our results depending on the reponse code:
366 [code=varnish]
367 sub vcl_fetch {
368 if (req.url ~ "^/webservice/uri/prefix/") {
369 if (beresp.status == 404) {
370 set beresp.ttl = 7d;
371 }
372 if (beresp.status == 410) {
373 set beresp.ttl = 7d;
374 }
375 if (beresp.status == 200) {
376 set beresp.ttl = 24h;
377 }
378 }
379 }
380 [/code]
381
382 With this configuration, we divided by 5 the quantity of request on our gateway
383 from the client who was not able to cache our result himself.'
