ijar's problem

[Uldiniad]

• Your Windows build number: Microsoft Windows [Version 10.0.17661.1001]

• Steps to reproduce:

1. git clone https://github.com/LineageOS/android_prebuilts_build-tools.git
2. cd android_prebuilts_build-tools/linux-x86/bin/
3. wget https://github.com/cs-au-dk/thor/raw/master/tools/jacocoant.jar
4. ./ijar jacocoant.jar

• What you're doing and what's happening:
  I'm attempting to run ijar on wsl and consistently get this output on .jar files
  ftruncate(fd_out, GetSize()): Invalid argument Aborted (core dumped)

• What's wrong / what should be happening instead:
  should successfully complete as on native Ubuntu

• Strace of the failing command, if applicable:

Some more repro steps would be useful.

@benhillis I've added the repro steps, I apologize that I can't make it much simpler than this.

Ref #2948 and #1771. Ben at the end of the day this is going to take downloading Lineage and having a long look. Fail here is ftruncate(fd_out, GetSize()): Invalid argument, which is a different mode than the others.

mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f63893e0000
openat(AT_FDCWD, "/home/Uldiniad/android/lineage/out/target/common/obj/JAVA_LIBRARIES/sdk_v8_intermediates/classes.jar.toc.tmp", O_RDWR|O_CREAT|O_TRUNC, 0644) = 4
ftruncate(4, 4891983)                   = 0
mmap(NULL, 4896079, PROT_WRITE, MAP_SHARED, 4, 0) = 0x7f6387600000
brk(0x7fffeb62b000)                     = 0x7fffeb62b000
[... more brks]
brk(0x7fffeb6b2000)                     = 0x7fffeb6b2000
ftruncate(4, 2394654)                   = -1 EINVAL (Invalid argument)
write(2, "ftruncate(fd_out, GetSize()): In"..., 47) = 47

I mean, for shorter repro it could be a matter of just cloning the repository containing the tool that fails. In this case ijar which is here: https://github.com/LineageOS/android_prebuilts_build-tools/tree/lineage-15.1/linux-x86/bin and run it against some test files.
Also, it is worth noting that I have a workaround (can be labelled workaround-available) on the OP, may help in finding the issue.
Also worth noting that both ijar and dex2oat are used on aosp as a whole. This is not isolated to lineage, I compile that rom because I prefer it to aosp.

Easiest repro on build 17134.48

git clone https://github.com/LineageOS/android_prebuilts_build-tools.git

cd android_prebuilts_build-tools/linux-x86/bin/

wget https://github.com/cs-au-dk/thor/raw/master/tools/jacocoant.jar

./ijar jacocoant.jar

ftruncate(fd_out, GetSize()): Invalid argument
Aborted (core dumped)

thanks @onomatopellan

@benhillis just wanted to note I've simplified the strace and the steps to reproduce on the OP as much as I could. should be simple to figure what's going on

[therealkenc]

should be simple

Indeed. #902
