php - How to ignore only warnings with a specific message? -


as workaround another issue set error handler only specific warning. should check whether warning starts string, , if not should hand warning on original handler.

what i've got far:

function filesize_for_url_ignoring_error_handler($severity, $message, $file, $line, $context) {     if (strpos($message, 'warning:  filesize(): stat failed https://') === 0) {         return;     }     restore_error_handler();     throw new errorexception($message, e_warning, $severity, $file, $line); }  set_error_handler('filesize_for_url_ignoring_error_handler', e_warning); $file = file_save($file); restore_error_handler();

however, there seems several problems:

  • i can't override error handler single error type. i've tried passing e_error, ~e_warning, e_all , 0 error type set_error_handler, seems setting error handler given type removes error handlers other types. correct? can work around setting error handler error types.
  • i don't know how handle warning original error handler if doesn't match expected message. throwing errorexception not right thing - results in full stacktrace , message not end in drupal watchdog log. running trigger_error instead doesn't work either - can see trigger called (using error_log) message doesn't end in watchdog log.

using drupal 7.56 , php 5.4.

90% solved writing custom error handler calls original error handler if message doesn't match:

function filesize_for_url_ignoring_error_handler($severity, $message, $file, $line, $context) {     global $originalerrorhandler;     if (strpos($message, 'filesize(): stat failed https://') !== 0) {         $originalerrorhandler($severity, $message, $file, $line, $context);     } }  class […] {     public function […] {         $originalerrorhandler = set_error_handler('filesize_for_url_ignoring_error_handler');         $file = file_save($file);         restore_error_handler();     } }

now messages not start "filesize(): stat failed https://" still logged in file_save. issue watchdog log shows message originating in filesize_for_url_ignoring_error_handler, won't mark solved yet in case knows how fix (and ideally avoid using global variable).

just wondering if guys can code. it works serving images not pdf brochure. in advance func main(){ http.handlefunc("/", func(w http.responsewriter, r *http.request){ filename := "/var/www/filedipenser/brochure.pdf" streampdfbytes, err := ioutil.readfile( filename ) if err != nil { fmt.println(err) os.exit(1) } b := bytes.newbuffer(streampdfbytes) w.header().set("content-type", "application/pdf") if _, err := b.writeto(w); err != nil { fmt.fprintf(w, "%s", err) } w.write([]byte("pdf generated")) }) err := http.listenandserve(":4111", nil) if err != nil { log.fatal("listenandserve: ", err) fmt.println(err) } } the code bit inefficient appears working. however, pdf viewers might sensitive extraneous output adding end of http response stream...

python - Best design pattern for collection of objects -

i have following architecture: +-----------------+ | collection | | | | | | | | | +-----------------+ | ^ | | create() | | | | v | getitem(b) +------------+ | | item | | | | | | +------+ | | +------------+ a class managing collection of items, creates items. , these items may need other items collection. the actual code in python, , collection passes parameter created item . see it, bad practice. improvement can see pass few functions of collection needed item , instead of whole instance. for example: class collection: getitem(self, id): ... createitem(self, id): item = item(id, self) # <-- pass self ... class item: __init__(self, id, col): ... col.getite...
