BREAKING - Upgrade to upstream newlib 4.0.0 release #7708
Conversation
Includes 64 bit time_t and 5 years of updates. Binary incompatible with libraries which use time_t (due to the size difference). Recompiling with the new newlib should be sufficient for most libraries, assuming source is available.

Note that this requires a new toolchain (since GCC includes newlib), so be sure to run |
Upgrade to Newlib 4.0.0 tag. The toolchain should be rebuilt before any merge as it still contains a copy of newlib 3.3.0. Only 1 incompatibility seen with internal TZ structures requiring a minor patch to the core.

The CI caching doesn't pick up updated toolchain releases, so for now dieable it until get.py becomes a little smarter and allows for removing MD5-mismatched files.
Somewhere along the line the copy of libc in tools/sdl/libc was taken out of the build process. Files in there are not used, take add'l time to build and install on a toolchain release, and just cause confusion. Remove them.

Quiet impressed. With your latest commits Tasmota does compile successfull and it does start!! |

@Jason2866 one thing to be aware of, maybe related to the NTP stuff: If you've got a binary struct saved somewhere (say, with last time updated), the size of that struct will now change and you'll probably be interpreting garbage at that point (4->8 byte time_t).
LittleFS timestamp handling now working w/64-bit times. FAT should already be safe until 2107 per Wackypedia. |
The core was setting 64-bit times automatically on new file creation or updates, but would fail when attempting to read them back due to 64/32b confusion. Now attempt to read 64b time, and if that fails fallback to reading 32b time to allow both old and new FS to preserve timestamps.
@jjsuwa-sys3175 contributed three additional optimization .MD patches for GCC 10.2, as well as a slightly faster pgm_read_byte() macro. Rebuild the toolchain using these new changes.

iirc, changing 'key' will force it to use a different cache
it will be expired at some point, but it is not as clear as something like travis (rip)

Thx. I think generally we're OK and the un-done patch here was just a stopgap during development.
The original commenting-out was because the releases have a datestamp in them which ends up making all builds in a day conflict. So get.py would find gcc-20121101.tgz(from 9AM) in the cached dir and not try and d/l the newer one gcc-20121101.tgz(from 11AM). The cached version's MD5 would mismatch, so the build failed w/o a toolchain. Easy fix, drop the caching. W/everything coming from GH.com, anyway, the cache probably doesn't make much difference...

True, speeds on github are really good, so cache most of the time takes longer than just fetching the sources directly...
I think it also could be this 'template', making key depend on the .json so it is always new whenever toolchain is modified
key: ${{ runner.os }}-${{ hashFiles('package/package_esp8266com_index.template.json') }}

That's an awesome idea! Right now the cache will grow w/obsolete versions of the tools, but one based on the JSON would fix that problem.
Did you want the PR for this? OTW I can throw it together quickly.
