Django-compressor: El análisis de las URL de datos entre comillas puede producir citas incorrectas en compressor.filters.css_default.CssAbsoluteFilter

parece un duplicado de https://github.com/django-compressor/django-compressor/issues/827. la solución está en django-compressor 2.2, asegúrese de que está utilizando la última versión. si el problema persiste, volveremos a abrir, por supuesto :)

@karyon En realidad, estoy teniendo exactamente el mismo problema y estoy usando django-compressor 2.2.

bueno, mierda :) Lo echaré un vistazo en los próximos días con suerte.

@shezi , @ Hybridx24 , ¿qué versión de bootstrap exactamente? beta1?

De hecho, estoy usando Bootstrap 3.3.6, pero el problema se me ocurre cuando uso mi propio SVG personalizado (que funciona perfectamente antes de la compresión). Parece que, como dijo el OP, algo se está rompiendo dentro de background-image: url("data:image/svg+xml;...")

Estoy usando Bootstrap v4.0.0-alpha.6 y tengo el mismo problema. Sería bueno si pudieras arreglar esto

@ Hybridx24 , @Renatello , por favor @shezi en una prueba y en esa prueba, CSSAbsoluteFilter no lo cambia en absoluto.

Rendimiento esperado:
Desconocido, pero puede probar pegando código CSS base64 en la barra de URL y ver si funciona correctamente.

eso también se comprime bien para mí :( ¿podría darme su settings.py, un poco más de contexto del archivo css (idealmente todo) y la plantilla donde está incluyendo esto?

@karyon El CSS es en realidad solo una anulación de la flecha siguiente / anterior para swiper.js, por lo que el resto del código es en gran parte irrelevante. Todo lo que sé es que el CSS funciona perfectamente hasta que ajuste las etiquetas {% compress css %} alrededor de mi archivo swiper-overrides.css . El error que obtengo es:

RCSSmin también destruye la misma regla de Bootstrap 4, aunque de una manera diferente a la que supongo que hizo CssAbsoluteFilter ; el minificador elimina los espacios de los datos: URL. Entonces, si tiene problemas con una versión de django-compressor que ya tiene este error corregido, es posible que esté presionando ndparker / rcssmin # 8 en su lugar.

Releyendo esto y el # 910, me parece que el problema original (citas incorrectas) se ha solucionado y el problema restante (espacio en blanco eliminado) se describe en el # 910. gracias @ Hybridx24 , @jsma y @jameysharp.

Por lo que vale, me he encontrado con el mismo problema cuando se habilitó compressor.filters.css_default.CssAbsoluteFilter y comprimí Bootstrap 4.

@dwasyl ¿ RCSSmin también estaba habilitado? ¿Puede pegar la salida de pip freeze, la entrada css, la salida real y la salida esperada?

@karyon Lo siento, no había vuelto a este proyecto en un tiempo. Estoy usando CSSMin, pero no RCSSMin.

Lo que veo como mi valor sin comprimir es esto:
url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' width='30' height='30' viewBox='0 0 30 30'%3e%3cpath stroke='rgba(255, 255, 255, 0.5)' stroke-linecap='round' stroke-miterlimit='10' stroke-width='2' d='M4 7h22M4 15h22M4 23h22'/%3e%3c/svg%3e)

Luego, después de la compresión:
url("data:image/svg+xml,%3csvgxmlns='http://www.w3.org/2000/svg'width='30'height='30'viewBox='003030'%3e%3cpathstroke='rgba(255,255,255,0.5)'stroke-linecap='round'stroke-miterlimit='10'stroke-width='2'd='M47h22M415h22M423h22'/%3e%3c/svg%3e)

En la configuración, tengo:

COMPRESS_CSS_FILTERS = [
    'compressor.filters.css_default.CssAbsoluteFilter',
    'compressor.filters.cssmin.CSSMinFilter'
]

En cuanto a la congelación de PIP:

django-compressor==2.2
rcssmin==1.0.6

Gracias. que de hecho se parece al # 910.
