- Subject: [PATCH 1/2] unzip: reduce file name size to 65535 to work with
- external minizip
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
-
- The external minizip project has changed the unzGetCurrentFileInfo()
- function to take a uint16_t as the filename size, instead of a uLong
- as in the original version in zlib.
-
- (Reported as https://github.com/nmoinvaz/minizip/issues/490 but it
- was 3½ years ago and might be too late to fix it now, although changing
- it back to a *larger* type is a lot safer than reducing the size, and
- perhaps they should.)
-
- This means that our 65536-byte buffer gets truncated to zero, as the
- compiler tells us when we build agaisnt the external minizip:
-
- domoticz/main/unzip_stream.h:140:50: warning: conversion from ‘long unsigned int’ to ‘uint16_t’ {aka ‘short unsigned int’} changes value from ‘65536’ to ‘0’ [-Woverflow]
- 140 | unzGetCurrentFileInfo(handler_, &info, path, sizeof(path), NULL, 0, NULL, 0);
- | ^~~~~~~~~~~~
-
- Reduce the buffer size to 65535 bytes instead.
