Req #73716 [Fbk]: PHP 7.1's CHCP switching in console should be optional

Edit report at https://bugs.php.net/bug.php?id=73716&edit=1 ID: 73716 Updated by: ab@php.net Reported by: anrdaemon at freemail dot ru Summary: PHP 7.1's CHCP switching in console should be optional Status: Feedback Type: Feature/Change Request Package: Output Control Operating System: Windows PHP Version: 7.1.0 Block user comment: N Private report: N New Comment: @anrdaemon, i'm really not sure about Far manager - it is a good software, and it also can support Unicode. Any program can update codepage at runtime, but that's not going to work well, especially if no TrueType font is used. Nevertheless, I've pushed a patch to support output_encoding different from the internal one, please test latest snapshots. There is no default behavior change. You can experience any kind of mojibake, if you work internally with the encoding different from the output, but that is your responsibility then. Yasuo, I've also asked teh reporter in bug #73716 to check the usecase with Japanese locale. To the times I was testing the multibyte implementation, I was able to verify it and it seems a quite weird issue with both codepage and the font. I guess, this can also fix issues with similar multibyte codepages, however i saw not reports yet. I'm going to document the crashing case in the UPGRADING, and also the changes done in this patch, if it goes well. Thanks.

Since half the > extensions can't be loaded. 1) I guess you installed half of extensions under multibyte pathname. Is this correct? 2) I suppose if you locate these extensions to single byte pathname, then they are loaded. Is this correct? 3) I use Windows version on occasion so I could be wrong, but doesn't multibyte pathname cause file access problem on older PHPs? 4) Your problem is code page change on Windows, so you are suggesting enable it like php --chcp some.php on Windows? (or --chcp-off to disable) 5) In case of abnormal exit, user may execute "chcp CODEPAGE". This could be documentation problem. Is this enough for you? ------------------------------------------------------------------------ [2016-12-13 19:29:46] anrdaemon at freemail dot ru "Extensions not loaded" with subsequent process interruption was how I first stumbled upon this issue. A worst case scenario, if you wish. I since found the way to reliable trigger it under normal circumstances. Asking for "reproduction with cmd" isn't fair, CMD itself doesn't update console buffer in realtime (nor is CMD strictly required to be present, to begin with… 99% of the time I don't use it at all, running PHP scripts straight from other programs though its association). ------------------------------------------------------------------------ [2016-12-13 18:31:29] ab@php.net So it doesn't load extension, while under Far manager? What is internal redirect? Preferably it should be reproducible with the pure cmd. Thanks. ------------------------------------------------------------------------ [2016-12-13 18:24:01] anrdaemon at freemail dot ru Reproduction case? Get Far manager (+FAR Commands plugin, which is part of standard package - farmanager.com/download.php ), start PHP 7.1 with internal redirect… view:<? php -d internal_encoding=utf-8 -r "sleep(3);" …observe console corruption for the duration of script execution. May be not the most self-container demonstration, but very much visual. Works equally well with CP437. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
